The 1 should not be because although the clinical picture is suggestive, it does not present lymphocytosis. What points to dengue, in addition to the clinical signs, is the plateletopenia.

In this case I believe that the correct answer is 5. The 1 should not be because although the clinical picture is suggestive, it does not present lymphocytosis. It does not seem to be an allergic exanthema from the clinical picture. And certainly she does not have symptoms or clinical signs compatible with malaria or typhoid fever. What points to dengue, in addition to the clinical signs, is the plateletopenia.

A 32-year-old woman has traveled to Cuba from where she arrived three days ago. The day after her return, she goes to her family doctor for high fever, intense arthromyalgia and headache that had started before the return trip and he prescribes her paracetamol. Three days later and with no improvement, he presented in the morning with a generalized pruritic maculo-papular rash, which was more intense on the lower limbs where it developed into petechiae, for which he went to the emergency department. There is no relevant data in the EC except platelets 75000/mm3 (htco 36%, leukocytes 4100 79% neutrophils). What is the most likely diagnosis?

Philip J. Rosenthal, MD A 5-year-old American girl presents with a 1-week history of intermittent chills, fever, and sweats. She had returned home 2 weeks earlier after leaving the USA for the first time to spend 3 weeks with her grandparents in Nigeria. She received all standard childhood immunizations, but no additional treat-ment before travel, since her parents have returned to their native Nigeria frequently without medical consequences. Three days ago, the child was seen in an outpatient clinic and diagnosed with a viral syndrome. Examination reveals a lethargic child, with a temperature of 39.8°C (103.6°F) and splenomegaly. She has no skin rash or lymphadenopathy. Ini-tial laboratory studies are remarkable for hematocrit 29.8%, platelets 45,000/mm3, creatinine 2.5 mg/dL (220 μmol/L), and mildly elevated bilirubin and transaminases. A blood smear shows ring forms of Plasmodium falciparum at 1.5% parasit-emia. What treatment should be started?

First case of imported chikungunya infection in Croatia, 2016.

In recent years, several European countries reported cases of imported chikungunya infection. We present the first imported clinically manifested chikungunya fever in Croatia. A 27-year-old woman returned to Croatia on 21 March 2016, after she stayed in Costa Rica for two months where she had noticed a mosquito bite on her left forearm. Five days after the mosquito bite she developed severe arthralgias, fever and erythematous papular rash. In next few days symptoms gradually subsided. After ten days she felt better, but arthralgias re-appeared accompanied with morning stiffness. Two weeks after the onset of the disease she visited the infectious diseases outpatient department. The physical examination revealed rash on the trunk, extremities, palms and soles. Laboratory findings showed slightly elevated liver transaminases. Serological tests performed on day 20 after disease onset showed a high titer of chikungunya virus (CHIKV) IgM and IgG antibodies which indicated CHIKV infection. CHIKV-RNA was not detected. Serology to dengue and Zika virus was negative. The patient was treated with nonsteroid anti-inflammatory drugs and paracetamol. Her symptoms ameliorated, however, three months later she still complaint of arthralgias. The presented case highlights the need for inclusion of CHIKV in the differential diagnosis of arthralgia in all travelers returning from countries with documented CHIKV transmission.

Fever in returning travelers: a case-based approach.

Overall, 3% to 19% of travelers to the developing world will return to the United States with fever or will develop fever within weeks of their return. When evaluating the returning traveler with fever, it is important to know which pretravel immunizations the patient received; which medications he or she took during travel; the likely pathogen exposures during travel; and the incubation interval between travel and onset of fever. A physical examination that includes a search for focal findings may narrow the list of possible infections. Fever compatible with a common illness that occurs in the United States (e.g., mononucleosis) should always be considered. If the patient has fever without a focus and a tropical infection is suspected, malaria, dengue fever, and typhoid fever are common causes. These infections may appear clinically similar, with symptoms of fever, headache, muscle pain, joint pain, and malaise, and decreased white blood cell and platelet counts. Malaria can usually be diagnosed with a thin blood smear. Dengue fever is a clinical diagnosis. Serologic testing for dengue virus immunoglobulin M and G and virus detection tests can be performed to confirm the diagnosis, but are not immediately available. Typhoid fever can usually be diagnosed with a blood, urine, or stool culture.

[Meningococcemia: Different Serotypes in the Same Region].

Meningococcal infections are important health problems causing high morbidity and mortality. Neisseria meningitidis have 13 serogroups. A, B, C, Y and W135 are the most common causes of invasive disease among those serogroups. The distribution of the serogroups differs according to the geographical regions and the age groups. In this case report, two cases of meningococcemia infected with serogroup C and Y of N.meningitidis rarely seen in our country were presented. First case was a two and a half year-old female patient who has admitted to our pediatric emergency unit with fever and rash spreading from lower extremities to her body. The patient had diffuse purpuric rash with generalized weakness and tendency to sleep at admission. The patient has been suspected as meningococcemia because of the skin rash, tendency to sleep and hypotension. Antibiotics treatment was started immediately and lumber puncture was performed. In blood tests, leukocyte count: 3600/mm3 (61% neutrophils), hemoglobin: 11.1 g/ dl, platelet count: 127.000/mm3 , C-reactive protein: 10 mg/dl, erythrocyte sedimentation rate: 6 mm/ hour, prothrombin time: 28.8 seconds (normal value= 11-16), prothrombin activity: 36%, international normalized ratio (INR): 2.13 (normal value= 1-1.5), activated partial thromboplastin time: 57.7 seconds (normal value= 25-35 sec), fibrinogen: 246 mg/dl (normal value= 200-400 mg/dl) and in cerebrospinal fluid protein: 21 mg/dl and glucose: 62 mg/dl were found. There were eight cells in the microscopic examination. Skin rashes were increased and the patient became hypotensive. No microorganisms were isolated in blood and cerebrospinal cultures. N.meningitidis serogroup C was isolated from the cerebrospinal fluid of the patient using polymerase chain reaction (PCR). The patient suffered from immune-mediated arthritis in the sixth day of treatment and nonsteroidal anti-inflammatory drugs were given. The patient has recovered with antibiotics, fresh frozen plasma and inotropic treatment. Second case was a 13 year-old male patient who has admitted three days after the first case with a pre-diagnosis of malignancy because of pancytopenia and fever. The patient had generalized weakness and a few petechial purpuric rashes at the facial region at admission. After the admission general status of the patient has worsened rapidly and he has died as a result of cardiovascular arrest. Blood tests in admission showed leukocyte count: 6000/mm3 (79% neutrophils), hemoglobin: 17.3 mg/dl, platelet count: 16.000/mm3 , C-reactive protein: 8.63 mg/dl, prothrombin time: 92.6 seconds, prothrombin activity: 10%, INR: 6.78, activated partial thromboplastin time: 231.5 seconds. Cerebrospinal fluid obtained from postmortem lumbar puncture showed no growth (protein: 95 mg/dl, glucose: 35 mg/dl) and N.meningitidis serogroup Y was detected by PCR. Two meningococcemia cases caused by two different serogroups which are rarely seen in our region in recent years were presented at the same time period in the same hospital. This case report pointed out that surveillance has a great importance in such diseases.

The spotted traveller.

A 23 year old university student comes to see you with a febrile illness and a rash. She has just returned from a 6 week holiday in South East Asia having visited Thailand, Vietnam, Hong Kong and the Philippines. Prior to going away she went to a travel clinic, was appropriately immunised and given malaria prophylaxis which she has taken assiduously. Her symptoms have been present for about 3 days and consist of severe retro-orbital headache, diffuse myalgias, fevers and chills, and anorexia. The rash appeared the day before on her trunk and is now beginning to involve her arms with a slight papular element. She also has conjunctival haemorrhages and is febrile with a temperature of 38.9 degrees C. A full blood count done urgently does not show any malaria parasites but does reveal a low platelet count of 85,000 x 10(6)/L.

[Post-infectious systemic vasculitis: recovery without corticotherapy].

In the most cases the causes of systemic vasculitis are unknown and treatment is symptomatic (corticosteroids often associated with immunosuppressive agents). We report three cases of systemic vasculitis associated with infections for which dramatic improvement was observed without cortico-therapy (in two patients). CASE REPORT 1: A previously overweight 72-year-old woman was admitted because of a one-year history of fever, fourteen kilogram weight loss, vascular purpura, and polyneuropathy. Abnormal laboratory values included inflammatory syndrome [erythrocyte sedimentation rate (ESR): 80mm/first hour, thrombocytosis: 500,000/microliter, hypereosinophilia (1200/microliter) and positive perinuclear anti-neutrophil cytoplasmic antibodies (p-ANCA) [anti-myelo-peroxydase antibodies: 30 U (normal < 7)]. Neuromuscular biopsy showed necrotizing vasculitis involving small and medium arteries. Further studies revealed a florid diverticulosis of the colon and no other severe visceral involvement. Treatment was started then with sigmoidectomy. Within six weeks her general condition improved dramatically without corticotherapy: regression of all systemic manifestations, the ESR normalized, and p-ANCA became negative. Ten months later she was still asymptomatic. CASE REPORT 2: An 50-year-old-man developed a progressive fifteen-kilogram weight loss (within 2 months), severe polyneuropathy of all four limbs. His ESR was 120 mm/first hour, and C-reactive protein 200 mg/l. Neuromuscular biopsy showed necrotizing vasculitis affecting small vessels in the nerve and no immune deposits. Stomatologic examination revealed a multiple foci of dental infections. The extraction of all these foci of infections associated with antibiotics improved dramatically all systemic manifestations (within eight weeks), once more without corticotherapy. Eight months later the patient remained asymptomatic. CASE REPORT 3: A 30-year-old-woman was admitted because of five-week history of fever, myalgias, polyarthritis, and cutaneous nodules in her limbs. Abnormal laboratory values included inflammatory syndrome, proteinuria of 0.7 g/day, and a significant rise in Chlamydia trachomatis antibodies titres from 1/64 to 1/256 over a 5 week period. She had a previous history of genital condyloma. The prednisone initialed (0.5 mg/kg/day) twelve days prior to admission was gradually reduced (stopped within 2 months) and treatment with doxycycline (200 mg/day) was initiated. Within six weeks of antibacterial treatment we assisted to a total regression of the initial clinical manifestations and laboratory values became normalized. Ten months later she remained asymptomatic. In systemic vasculitis, investigations in a search of foci of infections are of dual interest: possible etiologic agent like our case reports (strong evidence for an infectious association) and, from a therapeutic perspective, we must identify the microbes behind vasculitis syndromes, since treatment with corticosteroids may have serious consequences if the patient has an active infectious disease.

[Travel Related Fever and Rash: Two Cases of Dengue Fever].

The frequency of travel-related infections in the world has increased due to the easily and widespread use of travel facilities in the 21st century. Vector-borne diseases are an important part of infectious diseases. Dengue fever is one of the travel-related infections that has been reported increasingly in recent years through the development of diagnostic methods. The aim of this report was to present two Dengue fever cases originating from travel. There was a story of mosquito bite during a trip to Sri Lanka travel in our first case. The patient was 30 years old and maculopapular rash appeared on the fifth day of contact. Three days after the onset of the rash, she has admitted to our clinic, complaining with fever and chills. Increased leukopenia and muscle enzymes were detected in the laboratory analysis. Real-time reverse transcriptase polimerase chain reaction (RT-PCR) was positive in the serum sample. The patient was followed up with supportive care and discharged by improvement. The second case, a 24-year-old male, had a story of mosquito bite during his trip to Malaysia. After the patient complained of fever, chills, fever, nausea, vomiting and muscle pain, the Dengue virus (DENV) NS1 antigen test performed in this country was found to be positive. In the second case, there was no maculopapular rash and laboratory analysis showed an increase in leukopenia, thrombocytopenia and muscle enzymes. RT-PCR positivity was detected in the serum sample. The patient was followed up with supportive treatment and discharged with cure. DENV infections are caused by DENV which is common in the tropical areas of the world. There are four DENV-1, DENV-2, DENV-3 and DENV-4 serotypes. DENV infections can present different clinical manifestations such as asymptomatic disease, viral syndrome, Dengue haemorrhagic fever, and Dengue shock syndrome. Dengue fever is often accompanied by arthritis, maculopapular rash and high fever. Our cases were defined as Dengue fever according to this definition. In the diagnosis of the disease, it is necessary first to be suspicious of the disease and the travel history must be questioned. In the definitive diagnosis, virus isolation, antigen, nucleic acid detection and serological tests are used. The virus can be isolated from blood, serum, urine and tissues. In the first five days after beginning of the symptoms associated with DENV infections, serum RT-PCR and Dengue NS1 antigen test may be positive.

[Two travellers suffering from typhus].

Endemic typhus, caused by Rickettsia typhi, belongs to the typhus group of the rickettsioses. The disease is prevalent worldwide and is probably an underestimated cause of illness accompanied by fever in travellers, due to its frequently mild presentation and resemblance to diseases like typhoid- or dengue fever. Broad-spectrum antibiotics are not effective in the treatment of endemic typhus, but the disease is responsive to doxycycline. A 57-year-old man and a 36-year-old woman, who had returned from Indonesia and Nepal and Tibet, respectively, both presented with fever, malaise, headache and arthromyalgia, and both developed a skin rash. A diagnosis of typhoid- or dengue-fever was suspected at first. The first patient improved after empirical treatment with doxycycline, the second recovered following treatment with azithromycin. Blood cultures and viral serology remained negative. Additional serology showed evidence of infection with R. typhi. Both patients made a complete recovery. Endemic typhus should be included in the differential diagnosis of illness accompanied by fever in travellers, especially if blood cultures remain negative and no improvement is seen with broad-spectrum antibiotics.

First Iranian imported case of dengue.

Dengue fever, a mosquito-borne flavivirus infection, is endemic in Southeast Asia. Currently, incidences have been increasing among adults. There have been no published reports of dengue fever from Iran. Widespread connection between different countries may predispose them for acquisition of infection. The patient was a 58-year-old Iranian woman with acute unexplained high-grade fever for 4 days, associated with skin rash, after returning from Southeast Asia. CBC showed WBC = 1600/mm(3) and platelet count 99,000/mm(3). The patient also had hematuria. ELISA immunoglobulin M (IgM) antibodies to dengue and serum RT-PCR for dengue virus was positive. The patient managed with conservative treatment and due to good general condition and improvement specific antiviral treatment was not started. She became afebrile at the 3(rd) day of hospitalization and discharged with good general condition on fourth day. She was afebrile after two weeks follow-up. Dengue fever has been increasing among adults. It should be suspected, when a patient presents with acute febrile illness and skin rashes returning from endemic region. Conservative treatment may be conducted in uncomplicated cases.

The Biggest Loser Asia (season 1)

The next day, Damietta was suffering from a high fever. Despite taking medication and getting a dose of antibiotics from the doctor the night before, her condition still does not improve. The doctor becomes concerned that Damietta could be suffering from Dengue fever and decides that it is best to send her to the hospital for a blood test. Both teams experienced a rigorous bootcamp-style training in the mud and rain for their last chance workout. At the weigh-in, since Damietta still has not returned from the hospital, she was automatically excluded from the weigh-in, evening out the numbers between the blues and reds. Once again Tony needed 2 kg. He lost 5 and The Blue Team eventually won 27-23.

[Comparison of symptoms and clinical and laboratory findings in the first and last weeks of typhoid fever].

In this study we examined the clinical and laboratory findings of 80 in-patients. There is an important difference between sexes (p greater than 0.05). Comparison of ages showed that 7-30 age is more vulnerable than the older group. We found clinical symptoms of fever, chills, headache, abdominal pain, disturbances in bowel function, nausea, vomiting, anorexia, and lassitude in the first two weeks more frequently when compared with the 3rd, 4th, 5th weeks of illness (p less than 0.001). Where physical finding of rose spots, discordant pulse rate are important in the first two weeks (p less than 0.001). Abdominal discomfort is an important symptom both in the first two and in the last three weeks (% 40.3 and % 36 respectively). Hepatomegaly and splenomegaly, were found more frequently in the last three weeks. According to laboratory findings of anemia, leukopenia, increased erythrocyte sedimentation rate and positive blood and feces cultures there is no important difference between the first two and last three weeks (p greater than 0.05). Increase in polynuclear leucocytes is important for the first two weeks, and increase in lymphocytes is important in the last three weeks (p less than 0.001). Positivity of group agglutination tests is 57%, in the first two weeks and 83% in the last three weeks. This difference is found to be important.

[A Case of Dengue Fever and Subsequent Long-lasting Depression Accompanied by Alopecia in a Japanese Traveler Returning from Bali, Indonesia].

Recovery from dengue fever is generally rapid and uneventful. However, recuperation is often prolonged and may be accompanied by noticeable depression. We present herein on a traveler to Indonesia who developed long-lasting depression after the classic symptoms of dengue fever such as fever, arthralgia, and macropapular rash had resolved. A previously healthy 42-year old japanese woman presented to the Travel Clinic of Seirei Yokohama Hospital with complaints of 4 days of fever, joint aches, bone pain, and a macropapular rash on her torso. She had returned from Bali 5 days previously. During her 1-week stay, one day was spent in rural, mountainous areas where she was exposed to several mosquito bites. The 1st serum sample collected 4 days after the disease onset gave positive result in the rapid dengue IgM antibody test and the rapid dengue NS1 antigen immunechromatographic test. The DENV-1 genome was detected with RT-PCR. Her 13-year old son, who had accompanied her, was also diagnosed as having dengue fever and he recovered without event. The Above-mentioned symptoms resolved within one week. However, the patient suffered from prolonged depression. She also noticed loss of hair 3 months after the disease onset Administration of a Serotonin-Noradrenalin Reuptake Inhibitor and a minor tranquillizer required to allow her requied to lead a normal life. Although she gradually felt better, it took approximately 2 years until she had recovered completely without taking any antidepressant and minor tranquillizer. It is a well-known fact in endemic countries that dengue fever could have an significant impact on the patients' mental well-being. However, it appears that physicians in non-endemic countries are not fully aware of the prolonged depression, which can occur subsequent to the acute illness. Follow-up consultations of returing travelers who have recoverd from dengu fever should be arranged to monitor their mental and emotional states closely.

Adult-onset Still's Disease as a Differential Diagnosis in Prolonged Fever: Diagnosis and Treatment Experience.

Adult onset Still's disease is a rare systemic disease that may involve many organs and may mimick many disease such as infection, autoimmune disease, and also malignancy. The diagnostic approach and treatment strategies have not been well established due to its rarity; however, there are some diagnostic criteria that may help. We present a case of 36-year old man who experienced high prolonged fever which firstly thought as infection. He also had unilateral wrist and knee joint pain and maculopapular rash. Laboratory examination showed high leukocytes count with elevated polymorphonuclear neutrophil count, high platelet count, high ferritin level, and negative results of many infection markers (typhoid antibody, procalcitonin, malaria test, blood culture, urine culture, IgM pneumonia, ASTO, syphilis test, antiHIV, HBsAg, antiHCV, etc). Chest X-ray, joint X-ray, ultrasonography, and echocardiography showed normal result. The patient was then diagnosed with Adult-onset Still's disease and received intravenous methylprednisolone and the fever was disappeared in 3 days. Six months later the arthralgia appeared again, methotrexate was administered and the pain was then relieved.

Kikuchi-Fujimoto disease: an unusual presentation of meningitis in a returning traveller.

A 19-year-old, previously healthy woman developed a pruritic erythematous maculopapular rash on her bilateral palms and wrists, right-sided tender cervical lymphadenopathy and nightly fevers and headaches 5 days after returning from a 1-month trip to Cambodia. She presented 2 weeks after her trip due to ongoing nightly fevers to a maximum of 38.8°C. She was given empiric doxycycline for possible rickettsial disease, though an extensive infectious workup returned without positive findings. Lumbar puncture was performed on hospital day 4, and spinal fluid analysis was consistent with aseptic meningitis. On hospital day 5, core biopsy and fine-needle aspiration were performed on the largest anterior cervical lymph node. Her fever curve gradually improved, and she was discharged on hospital day 6. Results of the lymph node biopsy were finalized 5 days after discharge and were compatible with Kikuchi's lymphadenitis. Symptoms had completely resolved on follow-up with infectious disease and rheumatology.

[The 451(th) case: intermittent rash, fever and headache].

A 29-year-old woman was admitted to the Department of Rheumatology, Peking Union Medical College Hospital due to intermittent rashes, fever and headache. Palpable purpura were symmetrically distributed on the extremities and trunk. Other manifestations included headache with nausea and vomiting. Elevated white blood cell (WBC) count, platelet (PLT) count, erythrocyte sedimentation rate (ESR) and C-reactive protein were the main laboratory findings. Antinuclear antibodies and antineutrophil cytoplasmic antibodies were negative. Examination of the cerebrospinal fluid (CSF) revealed high intracranial pressure, while routine cytology and biochemical tests of CSF were normal. Head MRI scan and PET-CT did not detect remarkable findings. A diagnosis of systemic vasculitis was confirmed by the biopsy of skin lesion which showed inflammatory infiltration of the muscular vessel wall. Combination therapy of corticosteroids and cyclophosphamide lead to a rapid improvement in clinical symptoms and laboratory parameters. The patient was in stable remission till 6 month follow-up.

Blackwater Fever in Pregnancy With Severe Falciparum Malaria: A Case of Imported Malaria From Nigeria to the United Kingdom During the COVID-19 Pandemic.

We present the case of imported malaria in pregnancy to the United Kingdom (UK) from Nigeria, where a 28-year-old primigravida presented to our maternity assessment unit (MAU) with complaints of pyrexia, rigors and passing dark coloured urine. She gave a travel history of recent migration from Nigeria 10 days before presenting to our emergency department. She initially became unwell five days after her arrival with general malaise and myalgia. On day six, she developed lower abdominal pain and observed that her urine was dark in colour. This prompted her to contact her general practitioner (GP). Treatment for a urinary tract infection was initiated by the GP after a phone consultation in keeping with COVID-19 contingency guidance, and the patient was prescribed antibiotics for three days. She presented to the emergency department two days after completing the course of antibiotics where she complained of worsening pelvic pain, reduced foetal movements and passing black urine. She was treated as suspected COVID-19 and red flag sepsis. Obstetric review led to investigation and diagnosis of severe malaria in pregnancy, which was accompanied by blackwater fever (BWF). The patient recovered after three doses of artesunate. An ultrasound scan of the foetus revealed a congenital cardiac anomaly, which had not been detected in an earlier scan. There was no evidence of congenital malaria in the neonate after delivery. There are several novel aspects in this case as maternal mortality in severe <iPlasmodium falciparum</i can be significantly high. Those who survive the disease in pregnancy are also known to develop several complications such as intrauterine death and preterm labour. There was also the component of blackwater fever, which is a rare event associated with severe malaria, and it also has a mortality rate. Significant in her medical history was a diagnosis of the sickle cell trait, and we postulate that this feature gave an added protection from the complications of severe malaria in pregnancy as well as blackwater fever.

Infectious disease capsules: a pox on your house.

A 31-year-old, previously healthy white man presented to the emergency department with complaints of malaise, fevers, shortness of breath, a non-productive cough, and a "rash." His physical exam revealed a temperature of 100.2F, a pulse of 129 bpm, respiratory rate of 14 BPM, and blood pressure of 140/74 mm Hg. He was alert, oriented, and in no distress. His oropharynx was dry, his neck was supple, and cervical lymphadenopathy was absent. He had tachycardia, bilateral wheezes, and rhonchi with prolonged expirations. There was a diffuse vesicular eruption enveloping his entire body with involvement sparing his palms and soles (Figures 1 and 2). Laboratory values showed a hemoglobin of 16.0 g/dL and a white blood cell count of 7100 cells/pL, with 39%neutrophils, 23% bands, and 35% lymphocytes. His platelet count was mildly decreased to 86,000 x 103/pL. Chest radiograph revealed bilateral diffuse interstitial infiltrates. A diagnosis of acute varicella-zoster virus pneumonia (varicella pneumonia) was made, and the patient was started on IV acyclovir (10 mg/kg every 8 hours). Upon further questioning, the patient stated that his daughter had been diagnosed with "chickenpox" 7 days ago. The patient had numerous exposures to chickenpox in the past but had never developed clinical expressions of varicella. He was not at risk for HIV infection, not having multiple sexual partners, IV drug abuse, or blood transfusions. During the 1 day of in-hospitalization, his fever abated and the pulmonary signs diminished. Following discharge, IV acyclovir was replaced by valacyclovir to complete a 7-day course of therapy.

Two contrasting post-zoster dermatomal phenomena.

A 29-year-old, normotensive, nondiabetic man presented with a 9-day history of a scaly, pruritic eruption involving the right chest, axilla, and arm. He had a history of herpes zoster involving the same areas about 4 weeks ago. The present eruption started after the herpetic lesions had healed. Examination revealed scaly, erythematous plaques and papules involving the right side of the chest, axilla, and arm in a dermatomal pattern (figure 1). Removal of the scales revealed underlying bleeding points (positive Auspitz sign). The rest of the body, including scalp, palms, soles, and nails, were normal. There was no history suggestive of psoriasis in any family member. Systemic examination and routine investigations were noncontributory. A clinical diagnosis of psoriasis was made and confirmed by histopathologic examination of a skin biopsy sample. The patient was prescribed a topical clobetasol cream and oral levocetirizine. The eruption resolved completely after 3 weeks. A 43-year-old normotensive, nondiabetic woman presented with a 2-day history of fever, arthalgias, and generalized erythematous dermatitis. Five days ago, the patient had a toothache for which she was prescribed injectable ampicillin. After receiving ampicillin for 3 days, she developed fever, myalgias, and arthalgias, which was followed several hours later by an erythematous eruption. The dermatitis started on the trunk and, over a period of several hours, progressed to involve the face and limbs. The eruption was slightly pruritic. History revealed herpes zoster 7 months ago involving left thoracic dermatomes, for which the patient was treated with valacyclovir (1 g thrice a day x 7 days) and analgesics. There was no history of post-zoster neuralgia. On examination, the patient was febrile (oral temperature 102 degrees F), her heart rate was 118 beats per minute, and her blood pressure was 110/70 mm Hg. Cutaneous examination revealed an erythematous, maculopapular dermatitis involving the face and limbs in a bilaterally symmetrical pattern; the palms and soles were also bilaterally involved. The whole of the trunk was involved with erythematous and, in places, violaceous, maculopapular eruption except for a small area on the left side corresponding to T8 and T9 thoracic dermatomes (Figure 2). Complete blood cell counts revealed eosinophilia (9%) and liver function tests, kidney function tests, random blood sugar, routine urine examination, and blood and urine cultures were noncontributory. Histopathologic examination of lesional skin biopsy revealed an intense mononuclear cell infiltration with many eosinophils and an interface dermatitis with hydropic degeneration of basal keratinocytes, while in the spared area, only slight lymphocytic infiltration was present in a perivascular distribution. Based on the history and examination, a diagnosis of ampicillin-induced drug dermatitis was made. The ampicillin was stopped and the patient was put on a short course of oral prednisolone, antipyretics, and topical calamine. The patient was afebrile in 2 days and the eruption resolved completely in 8 days.

[Human granulocytic ehrlichiosis, a tick-borne disease].

A 69-year-old male presented at a first-aid department in Connecticut (USA) with severe headache, fever and myalgia of three days' duration. Just before he became ill, an engorged tick had been noted on his back and removed. Laboratory results included a decreased white cell count and platelet count and elevated transaminases. So-called morulae consisting of microorganisms were detected in a peripheral blood smear of the day of admission. Treatment for human granulocyte ehrlichiosis with doxycycline for two weeks resulted in prompt and full recovery and after four weeks repeat laboratory tests were all within normal limits. Human granulocyte ehrlichiosis should be considered in a patient with a recent tick bite who develops fever, headache and myalgias, in the presence of leukopenia or thrombocytopenia, even in Western Europe.

A fever from the tropics.

Shirley is a 42 year old woman who has rung you 5 days after returning from a 3 week resort holiday in Malaysia and Thailand. You saw her before her trip and administered a hepatitis A vaccine and advised her that she did not require anti malarial drugs as she was only going to large cities and beach resorts. She says she has had a high fever, headache and body aches for several days and that she feels exhausted, but is well enough to come to the surgery. When you see her later that morning, she looks fairly well, although she is moving rather gingerly. She says she has been resting, is drinking lots of fluids, has some anorexia, but no other significant symptoms. Examination reveals a temperature of 38 degrees C and she has a fine morbilliform rash on her body, limbs and neck. There are no other abnormal findings.

[Fever, headache, diarrhea].

A 26-year-old man suddenly developed fever, headache, pain in the lower extremities, diarrhoea, and lymphadenopathy on the way back from Thailand. Subsequently, leukopenia, thrombocytopenia, coagulation abnormality and a morbilliform exanthema were noted. With symptomatic treatment the patient could be dismissed in good health after nine days. The diagnosis of Dengue and Campylobacter jejuni/coli infection could be verified serologically by a rising antibody titer and by a positive stool culture respectively.

Vertical transmission of dengue: first case report from Bangladesh.

We report a case of vertical transmission of dengue infection in a new born from Bangladesh. The mother was primigravida with an uneventful antenatal period except the fever she developed at 37 weeks of gestation. She underwent cesarean section for decreased fetal movement. The fever lasted for 7 days and was associated with intense bodyache, and a positive tourniquet test. She did not experience any hemorrhages including from the surgical wound. Her platelet count fell at its lowest to 100,000/mm3. She had bilateral mild pleural effusions and positive anti-dengue antibodies (both IgG and IgM). She received symptomatic treatment. The baby was deeply meconium stained and was resuscitated by a pediatrician. His postnatal period went well until day-3 of life when he developed fever and respiratory distress. There were no signs of meconiun aspiration syndrome (MAS) and the septic work up was negative. The platelets count fell to its lowest of 40,000/mm3 on day-3 and day-5 of his illness. Anti-dengue antibodies (both IgG and IgM) were positive with a nearly four-fold rise of IgM antibodies in the convalescent sera. The boy was treated with platelet transfusions and was discharged on day-6 after becoming ill. This report emphasizes that in a dengue epidemic or when dengue is endemic (which Bangladesh has experienced recently), a pregnant woman with fever, myalgia and/or bleeding manifestations should raise a high suspicion that the baby may develop the disease, and both the mother and baby should be closely followed-up. Viral isolation could not be done due to the unavailability of the test.

[Hemorrhagic dengue and vertical transmission to the newborn: a case report and literature review].

To describe the case of a patient with term pregnancy and infection with hemorrhagic dengue and vertical transmission to the newborn. Thirty-two year old patient with pregnancy at 38 weeks was admitted with fever 2 days earlier (38 degrees C). During her stay she continued with fever of 39 degrees C and platelets of 85,000/mm3. Serology for dengue NS1 antigen was reported positive. Labor was induced getting a new-born, male, 3,220 g, who breathed and cried at birth. During the postpartum period continued with fever, malaise, retro-ocular pain, generalized rash in upper and lower limbs, bleeding gums and petechial on the soft palate and thrombocytopenia of 5,000/mm3, later. At 8 days of stay, platelet concentration increased to 42,000/mm3 without requiring platelet concentrates and she was discharged after ten days in hospital with platelets of 94,000/mm3. The 4th day of extra-uterine live (EUL), neonate shows generalized rash over the trunk; The 5th day starts with 38 degrees C fever and thrombocytopenia (78,000/mm3). Dengue serological tests reported positive for Ag NS1 and negative for Abs IgM and IgG. Neonate was admitted to NICU, he continued with a decrease in platelet of 14,000/mm3- and ecchymotic areas by pressure and veno-punction sites. Four platelet concentrates were transfused. At 10th day of EUL platelet count was reported with 387,000/mm3. In an endemic area, such as Sinaloa state, in a pregnant woman with fever and thrombocytopenia, we should be alert to possibility of a DV infection and its complications. Although rare, such as this case, infection can be transmitted to fetus (vertical transmission) and produce a primary congenital dengue, even in its severe hemorrhagic types.

What is that rash?

A healthy 15-month-old girl presented to the emergency department with a 24-hour history of fever and rash. The initial blanching rash developed into non-blanching areas with associated leg swelling. She had received no recent medications, had no known drug allergies and no unwell contacts.On examination, she was feverish at 38.6°C, capillary refill time was <2 s with warm peripheries, heart rate 169 bpm and blood pressure 94/59 mm Hg. A palpable purpuric rash was evident on all four limbs and face (figure 1) although the trunk was spared. Her legs were tense and oedematous to the knee.edpract;103/1/25/EDPRACT2016311782F1F1EDPRACT2016311782F1Figure 1Rash at presentation.Initial investigations: Haemoglobin level: 131 g/L, white cell count: 16.6×10<sup9</sup/L, neutrophils: 11.1×10<sup9</sup/L and platelets: 407×10<sup9</sup/LCoagulation screen: normalC reactive protein level: 20 mg/LLactate level: 1.7 mmol/LIntravenous ceftriaxone was commenced following blood culture and meningococcal PCR.

Diffuse rash and cough in elderly woman with a UTI.

A 66-year-old woman came into the emergency department with a diffuse rash and a cough. She had a rash on the palms of her hands, which had developed the day before, but had improved a bit. She also had a rash on her feet, legs, and lower abdomen, which had developed that morning. She said that over the previous 2 days she had had a fever, dry cough, and some difficulty breathing. Her past medical history was significant for asthma, diabetes, hypertension, and osteoarthritis. Her medications included atenolol, celecoxib, metformin, pioglitazone, and an albuterol inhaler, as needed. In addition, she was on the ninth day of a 10-day course of nitrofurantoin for acute cystitis. She was allergic to ampicillin and erythromycin. On physical exam, she had a fever of 101.5 degrees Fahrenheit. On lung examination, she had diffuse wheezes and mild bibasilar crackles. Examination of her skin revealed a nonpainful, nonpruritic, erythematous, maculopapular rash located on the palms and legs, as well as on her lower abdomen. Chest radiograph showed mild opacification in the bases of the lungs. What is your diagnosis?

[Relapsing fever after travelling in the tropics; a story with a twist].

Relapsing fever is an infectious disease caused by Spirochaetes. The presentation is characterised by recurrent episodes of fever. At the end of her trip through South Africa and Botswana, a 54-year-old woman had symptoms of fever and dry cough. Back in the Netherlands, physical examination at the emergency department did not reveal any abnormalities besides fever. Laboratory investigation found thrombocytopenia and elevated infection markers. Thick blood smear revealed the presence of Spirochaetes. Following a working diagnosis of 'relapsing fever', the patient was treated with doxycycline. There was no Jarisch-Herxheimer reaction. At a follow-up outpatient appointment two weeks later, the patient had fully recovered. Relapsing fever is a rare disease without specific symptoms. The diagnosis is therefore easily overlooked. Untreated, mortality is high. During episodes of fever, the diagnosis can be established with a thick blood smear.

Crimean-Congo hemorrhagic fever with hepatic impairment and vaginal hemorrhage: a case report.

Crimean-Congo hemorrhagic fever is a tick-borne disease described in more than 30 countries in Europe, Asia, and Africa. Albania is located in the southwestern part of the Balkan Peninsula. In 1986, the first case of Crimean-Congo hemorrhagic fever was registered, and cases of patients with hemorrhagic fever are rising, and most of them present in a serious condition, when the mortality rate is very high. In districts like Mirdite, Lezhe, Gjirokaster, Skrapar, Erseke, and Kukes, there is delineated human-to-human transmission. We report the case of a 32 year-old Albanian woman from a rural area of Albania. She was hospitalized at the Infectious Diseases Service, for a severe influenza-like illness of 4 days duration. Our patient had been bitten by a tick while working in her garden. She presented with nausea, vomiting, headache and muscle pain. A physical examination found a high fever of 40 °C, an enlarged liver, petechia, and vaginal bleeding; flapping tremor and fetor hepaticus were found as a sign for hepatic encephalopathy; and confusion and disorientation were observed in her neurological examination. Her platelet and white blood cell counts were very low, while her aspartate aminotransferase and alanine aminotransferase levels were very high. She was transferred to the intensive care unit because of her worsening condition. Serological and C-reactive protein test results for Crimean-Congo hemorrhagic fever were positive. She was treated with oral ribavirin and discharged with normal parameters. People in high-risk professions in the endemic areas should be informed and trained on the risk of Crimean-Congo hemorrhagic fever as a matter of urgency. Vaginal bleeding is not always a gynecological problem. In Albania, these places are the mountainous areas, so people who have traveled to these areas and who have symptoms after a tick bite are advised to contact their doctors.

[Henoch-Schönlein purpura associated with pulmonary tuberculosis].

A 34-year-old man was admitted to our hospital because of cough and fever. Chest radiograph showed multiple cavities mainly on the right lung. His sputum was positive for acid-fast bacilli on smear, and he was treated with daily isoniazide, rifampicin and streptomycin. Antituberculous treatment was successfully performed, so acid-fast bacilli of his sputa disappeared on smear and culture. Five months later, he developed a purpuric lesions over both legs accompanied by low grade fever and arthralgia, but proteinuria and abdominal pain could not be observed. Laboratory findings showed a normal platelet count and a normal bleeding time. High levels of serum IgG, IgA, C3 and C4 were evident. ASLO and ASK titer were elevated and they markedly increased within two weeks. A direct invasion of the vessel wall by tubercle bacilli is deniable because antituberculous treatment was successfully continued. Henoch-Schönlein purpura was diagnosed judging from these findings. High levels of ASLO and ASK suggest a preceding streptococcal infection for developing purpura but a possible infectious focus could not be identified. He was treated with 15 mg of prednisolone daily for two weeks and the lesion was subsided. The effect of prednisolone suggests that a subsequent antigen-antibody interaction caused by a streptococcal infection may participate in the formation of the purpura.

The DRESS syndrome: the great clinical mimicker.

The life-threatening DRESS (drug rash with eosinophilia and systemic symptoms) syndrome is characterized by the presence of at least three of the following findings: fever, exanthema, eosinophilia, atypical circulating lymphocytes, lymphadenopathy, and hepatitis. This syndrome is difficult to diagnose, as many of its clinical features mimic those found with other serious systemic disorders. This idiosyncratic reaction occurs most commonly after exposure to drugs such as allopurinol, sulfonamides, and aromatic anticonvulsants such as phenytoin, phenobarbital, and carbamazepine. We describe a 44-year-old woman who was brought to the emergency department with new-onset hemorrhagic stroke. She was admitted to the intensive care unit where she received supportive care that included clonidine and hydralazine for blood pressure control and phenytoin for seizure prophylaxis. On hospital day 21, the patient developed signs and symptoms of severe sepsis. Despite receipt of broad-spectrum antibiotics (vancomycin and piperacillin-tazobactam) and supportive care, the patient's clinical condition worsened with progressive jaundice, severe oliguria, and labile blood pressures. All cultures revealed no growth, and her chest radiograph remained clear. Several days after the onset of her fever, the patient developed several hematologic abnormalities including thrombocytopenia, with schistocytes present on a peripheral smear. She also had an elevated lactate dehydrogenase level. A provisional diagnosis of thrombotic thrombocytopenic purpura was made; however, the patient then developed severe facial edema, nearly global erythroderma, and severe exfoliative dermatitis. A punch biopsy of the skin was compatible with the DRESS syndrome. Phenytoin, vancomycin, and piperacillin-tazobactam were discontinued, and the patient was started on systemic corticosteroids, with rapid resolution of her fever and eosinophilia and progressive improvement in her skin rash and multiorgan system dysfunction. Use of the Naranjo adverse drug reaction probability scale indicated a probable relationship (score of 5) between the patient's development of DRESS syndrome and treatment with phenytoin. Clinicians should have a high index of suspicion for the DRESS syndrome in patients being treated with aromatic anticonvulsants who develop a sepsis-like syndrome. Furthermore, considering the potential severe effects associated with phenytoin, the risks and benefits should be carefully evaluated before using this agent for seizure prophylaxis.

[Pyrexia and hemoptysis for eight days in a school-age child].

A girl was diagnosed with intravenous immunoglobulin (IVIG)-resistant Kawasaki disease (KD) due to pyrexia and hemoptysis for eight days. The girl was a school-age child with major clinical manifestations of pyrexia, skin rash, enlargement of bilateral cervical lymph nodes, conjunctival hyperaemia, red and cracked lips and strawberry-like tongue, followed by swelling of both hands and feet. Laboratory examination showed significant increases in white blood cell count, platelet count, C-reactive protein, erythrocyte sedimentation rate and liver enzymes, a significant reduction in albumin, and the presence of aseptic pyuria. After the first course of IVIG treatment, the girl still had recurrent pyrexia, with hemoptysis on day 2 after admission, and lung CT showed uneven luminance and patchy shadow. The symptoms were quickly alleviated after the second course of IVIG treatment combined with methylprednisolone and aspirin treatment. KD is a febrile disease characterized by multiple systemic vasculitis in childhood and can involve various organ systems such as the heart, lungs, kidneys and the nervous system. Therefore, it is necessary to carefully monitor and recognize the rare symptoms of KD, and early recognition of pulmonary complications of KD can avoid delay in diagnosis, prevent the development of more serious complications, and help with early treatment and disease recovery.

[Sandfly fever-a "neglected" disease].

A 45-year-old woman presented at the outpatient department of a center for tropical diseases with fever, diarrhea, headache, myalgia, malaise, and an itchy papular rash. She had been on holiday with her family for 11 days in a mountain village in northern Cyprus. The place was infested with a lot of small, stinging flies or mosquitoes. She and her family became sick after they returned home. The physical examination was normal apart from the rash on the inside of the extremities. Significantly elevated transaminases and a slightly increased C‑reactive protein level were found in the blood examination. Considering the country of travel, the report of the "stinging flies" and the clinical presentation, sandfly fever was also taken into account as a differential diagnosis for the hepatitis. Antibodies to the sandfly fever Sicilian virus (SFSV) were detected. They showed the typical dynamics during the course of the illness and thus "pappataci fever" was diagnosed. The case report and a short review of up-to-date literature is meant encourage consideration of phlebovirus infection as a possible differential diagnosis in travelers or refugees suffering from severe febrile hepatitis and rash or aseptic viral meningitis after their stay in the Mediterranean area.
