There is controversy regarding etomidate because some text books (miller) consider it safe, while other (Lee, Wylie), consider it unsafe :-
Miller (7th/e 1115) has given etomidate amongst the safe drugs.
Lee and Wylie have opinion different to Miller :-
"Etomidate is potentially porphyriogenic in animal models and at least one crisis has followed its use in human subjects, although its safe use has also been reported, on balance, etomide should be considered unsafe".
─ Wylie
"Etomidate should probably be avoided because it is potentially porphyrinogenic in animals, although reports in humans are conflicting".
─ Lee
Anyways, whatever opinion about etomidate, the answer of this question is thiopentone for sure as there is no confusion about contraindication of barbiturates in porphyria. |

Anoxia means "lack of oxygen". It may be: (1) Anoxic anoxia: In this type, oxygen cannot reach the blood, because of lack of oxygen in the lungs. This occurs: (a) from breathing in a contaminated atmosphere, e.g., from exposure to the fumes in wells and tanks, or from exposure to sewer gas, (b) from mechanical interference with the passage of air into or down the respiratory tract, e.g., in smothering, choking, hanging, strangulation, drowning, traumatic asphyxia and ceain forms of acute poisoning. (2) Anaemic anoxia: In this type, oxygen-carrying capacity of the blood is reduced, e.g., acute massive haemorrhage, poisoning by carbon monoxide, chlorates, nitrates, coaltar derivatives. (3) Stagnant anoxia: In this type, impaired circulation results in a reduction of oxygen delivery to the tissues, e.g., hea failure, embolism and shock. ( 4) Histotoxic anoxia: In this type, the enzymatic processes by which the oxygen in the blood is used by the tissues are blocked, e.g., acute cyanide poisoning.

In children, GFRmeasured by inulin clearance is 110 ml/min/1.73m2 until 2 years of age in both sexes, and then it progressively decreases. After age 40, GFR decreases progressively with age, by about 0.4 - 1.2 mL/min per yearRef: Ganong&;s review of medical physiology; 24th edition; page no; 679 |

In the kidney there are two countercurrent mechanisms : - i) Countercurrent multiplier at the loop of Henle which generate high medullary osmotic pressure gradient; and ii) Countercurrent exchanger at vasa recta of medullary capillaires, which helps to maintain the medullary osmotic pressure gradient.Countercurrent multipliero The loop of Henle gives the nephron a peculiar shape. The descending limb, in which the tubular fluid flows towards the hairpin bend (downwords) and the ascending limb, in which the tubular fluid flows 'upwards' lie close to each other. Two such tubes with fluid flowing through them in opposite directions provide an opportunity for the countercurrent multiplication.o The thick ascending limb of loop of Henle is impermeable to water but it actively reabsorbs NaCl. The thin descending limb of loop of Henle is relatively impermeable to solutes but highly permeable to water. The most important cause of the high medullary osmolarity is active transport of sodium0 and co-transport of potassium, chloride and other ions out of the thick ascending limb of loop of Henle0 into the medullary interstitium. Most important among all these is NaCl0, for maintenance of high medullary interstitium.o Consider the Na* is continuously flowing in from glomerulus into the tubule. However, most of the Na+, instead of flowing out, gets trapped in a circular path and recycles between the ascending and descending limbs of the loop of Henle. Consequently, the Na* concentration becomes very high at the tip of the loop.Role of ureao Urea also contributes to the osmalority of medullary interstitium0, especially when the kidney is forming maximally concentrated urine. The medullary region ofthe collecting duct is permeable to urea. Diffusion ofurea from these ducts into the medulla increases the osmolarity of medullary' interstitium. Under the influence of ADH, the permeability of medullary collecting ducts to urea further increases. Moreover. ADH makes these collecting ducts also permeable to water and outward diffusion of wrater. That increases the urea concentration within the duct. That leads to further diffusion of more urea out of duct along concentration gradient. Thus urea makes an important contribution to the genesis of high osmolarity in the renal medulla.Countercurrent exchangero If the blood flowrs through the hyperosmolar medulla as shown in figure A below', it would equilibrate with medullary interstitium and carry away the solutes concentrated in the medulla. However, what actually happens is shown in figure 'BT below. Vasa recta is U shaped (as is the loop of Henle). As the vasa recta dips into the hyperosmolar medulla, the blood equilibrates with the surrounding interstitium and becomes hyperosmolar. Thereafter, as the vasa recta loops around and ascends towards the cortex, the osmolarity of the blood keeps decreasing as it equilibrates with the surrounding interstitium. By the time vasa recta leaves the medulla, the blood in it has the same osmolarity as when it entered the medulla. In other words, the solutes concentrated in the medulla are not wrashed away by the blood flowing through the medulla,o Since the blood flowing through the medulla equilibrates completely with the medullary' inerstitium, the amount of solutes carried away by the blood is flow limited. Hence, the slow rate of blood flow through the vasa recta contributes to the conservation of medullary hyperosmolarity. Conversely, a high blood flow rate through the medulla reduces the medullary hyperosmolarity'. |

Hemoglobin concentration o The rate of HbS polymerization is strongly dependent upon the hemologbin concentration per cell i.e., MCHC. o Higher HbS concentration increase the probability that aggregation and polymerization will occur during any given period of time. o Thus, intracellular dehydration, which increases the MCHC, faciliatates sickling. o Conversly, conditions that decrease MCHC reduce disease severity e.g., when sickle cell anemia occurs with athalassemia 3. Deoxygenation with HbS o Polymerization of HbS occurs only in deoxygenated state. o A decrease in pH reduces the oxygen affinity of hemoglobin, thereby increasing the fraction of deoxygenated HbS at any given oxygen tension and augmenting the tendency of sickling. 4. The length of time red cell are exposed to low oxygen tension. o Normal transient times for red cells passing through capillaries are not sufficient for significant aggregation of deoxygenated HbS to occurs. o Hence, sickling of red cells is confined to microvascular beds where blood flow is sluggish. o This is normally the case in spleen and bone marrow which are predominantly affected by sickle cell disease. |

It may be classified as neck pain (cervical), middle back pain (thoracic), lower back pain (lumbar) or coccydynia (tailbone or sacral pain) based on the segment affected. The lumbar area is the most common area affected. An episode of back pain may be acute, subacute or chronic depending on the duration. The pain may be characterized as a dull ache, shooting or piercing pain or a burning sensation. Discomfort can radiate to the arms and hands as well as the legs or feet, and may include numbness or weakness in the legs and arms.
The majority of back pain is nonspecific and idiopathic. Common underlying mechanisms include degenerative or traumatic changes to the discs and facet joints, which can then cause secondary pain in the muscles and nerves and referred pain to the bones, joints and extremities. Diseases and inflammation of the gallbladder, pancreas, aorta and kidneys may also cause referred pain in the back. Tumors of the vertebrae, neural tissues and adjacent structures can also manifest as back pain.
Back pain is common; approximately nine of ten adults experiencing it at some point in their lives, and five of ten working adults experience back pain each year. Some estimate that as many of 95% of people will experience back pain at some point in their lifetime. It is the most common cause of chronic pain and is a major contributor to missed work and disability. For most individuals, back pain is self-limiting. Most people with back pain do not experience chronic severe pain but rather persistent or intermittent pain that is mild or moderate. In most cases of herniated disks and stenosis, rest, injections or surgery have similar general pain-resolution outcomes on average after one year. In the United States, acute low back pain is the fifth most common reason for physician visits and causes 40% of missed work days. It is the single leading cause of disability worldwide.
Classification
Back pain is classified in terms of duration of symptoms.
Acute back pain lasts <6 weeks
Subacute back pain lasts between 6 and 12 weeks.
Chronic back pain lasts for greater than 12 weeks.
Causes
There are many causes of back pain, including blood vessels, internal organs, infections, mechanical and autoimmune causes. Approximately 90 percent of people with back pain are diagnosed with nonspecific, idiopathic acute pain with no identifiable underlying pathology. In approximately 10 percent of people, a cause can be identified through diagnostic imaging. Fewer than two percent of cases are attributed to secondary factors, with metastatic cancers and serious infections, such as spinal osteomyelitis and epidural abscesses, accounting for approximately one percent.
Nonspecific
In as many as 90 percent of cases, no physiological causes or abnormalities on diagnostic tests can be found. Nonspecific back pain can result from back strain or sprains, which can cause peripheral injury to muscle or ligaments. Many patients cannot identify the events or activities that may have caused the strain. The pain can present acutely but in some cases can persist, leading to chronic pain.
Chronic back pain in people with otherwise normal scans can result from central sensitization, in which an initial injury causes a longer-lasting state of heightened sensitivity to pain. This persistent state maintains pain even after the initial injury has healed. Treatment of sensitization may involve low doses of antidepressants and directed rehabilitation such as physical therapy.
Spinal disc disease
Spinal disc disease occurs when the nucleus pulposus, a gel-like material in the inner core of the vertebral disc, ruptures. Rupturing of the nucleus pulposus can lead to compression of nerve roots. Symptoms may be unilateral or bilateral, and correlate to the region of the spine affected. The most common region for spinal disk disease is at L4–L5 or L5–S1. The risk for lumbar disc disease is increased in overweight individuals because of the increased compressive force on the nucleus pulposus, and is twice as likely to occur in men. A 2002 study found that lifestyle factors such as night-shift work and lack of physical activity can also increase the risk of lumbar disc disease.
Severe spinal-cord compression is considered a surgical emergency and requires decompression to preserve motor and sensory function. Cauda equina syndrome involves severe compression of the cauda equina and presents initially with pain followed by motor and sensory. Bladder incontinence is seen in later stages of cauda equina syndrome.
Degenerative disease
Spondylosis, or degenerative arthritis of the spine, occurs when the intervertebral disc undergoes degenerative changes, causing the disc to fail at cushioning the vertebrae. There is an association between intervertebral disc space narrowing and lumbar spine pain. The space between the vertebrae becomes more narrow, resulting in compression and irritation of the nerves.Spondylolithesis is the anterior shift of one vertebra compared to the neighboring vertebra. It is associated with age-related degenerative changes as well as trauma and congenital anomalies.
Spinal stenosis can occur in cases of severe spondylosis, spondylotheisis and age-associated thickening of the ligamentum flavum. Spinal stenosis involves narrowing of the spinal canal and typically presents in patients greater than 60 years of age. Neurogenic claudication can occur in cases of severe lumbar spinal stenosis and presents with symptoms of pain in the lower back, buttock or leg that is worsened by standing and relieved by sitting.
Vertebral compression fractures occur in four percent of patients presenting with lower back pain. Risk factors include age, female gender, history of osteoporosis, and chronic glucocorticoid use. Fractures can occur as a result of trauma but in many cases can be asymptomatic.
Infection
Common infectious causes of back pain include osteomyelitis, septic discitis, paraspinal abscess and epidural abscess. Infectious causes that lead to back pain involve various structures surrounding the spine.Osteomyelitis is the bacterial infection of the bone. Vertebral osteomyelitis is most commonly caused by staphylococci. Risk factors include skin infection, urinary tract infection, IV catheter use, IV drug use, previous endocarditis and lung disease.
Spinal epidural abscess is commonly caused by severe infection with bacteremia. Risk factors include recent administration of epidurals, IV drug use or recent infection.
Cancer
Spread of cancer to the bone or spinal cord can lead to back pain. Bone is one of the most common sites of metastatic lesions. Patients typically have a history of malignancy. Common types of cancer that present with back pain include multiple myeloma, lymphoma, leukemia, spinal cord tumors, primary vertebral tumors and prostate cancer. Back pain is present in 29% of patients with systemic cancer. Unlike other causes of back pain that commonly affect the lumbar spine, the thoracic spine is most commonly affected. The pain can be associated with systemic symptoms such as weight loss, chills, fever, nausea and vomiting. Unlike other causes of back pain, neoplasm-associated back pain is constant, dull, poorly localized and worsens with rest. Metastasis to the bone also increases the risk of spinal-cord compression or vertebral fractures that require emergency surgical treatment.
Autoimmune
Inflammatory arthritides such as ankylosing spondylitis, psoriatic arthritis, rheumatoid arthritis and systemic lupus erythematosus can all cause varying levels of joint destruction. Among the inflammatory arthritides, ankylosing spondylitis is most closely associated with back pain because of the inflammatory destruction of the bony components of the spine. Ankylosing spondylitis is common in young men and presents with a range of possible symptoms such as uveitis, psoriasis and inflammatory bowel disease.
Referred pain
Back pain can also be referred from another source. Referred pain occurs when pain is felt at a location different than the source of the pain. Disease processes that can present with back pain include pancreatitis, kidney stones, severe urinary tract infections and abdominal aortic aneurysms.
Risk factors
Heavy lifting, obesity, sedentary lifestyle and lack of exercise can increase the risk of back pain. Cigarette smokers are more likely to experience back pain than are nonsmokers. Poor posture and weight gain in pregnancy are also risk factors for back pain. In general, fatigue can worsen pain.A few studies suggest that psychosocial factors such as work-related stress and dysfunctional family relationships may correlate more closely with back pain than do structural abnormalities revealed in X-rays and other medical imaging scans.
While back pain physical effects can range from muscle aching to a shooting, burning, or stabbing sensation. It can radiate pain down the legs and have pain increased by bending, twisting, lifting, standing, or walking. While the physical effects of back pain are always at the forefront back pain also has other psychological effects. Back Pain has been linked to depression, anxiety, stress, and avoidance behaviors due to mentally not being able to cope with the physical pain. “Both acute and chronic back pain can be associated with psychological distress in the form of anxiety (worries, stress) or depression (sadness, discouragement). Psychological distress is a common reaction to the suffering aspects of acute back pain, even when symptoms are short-term and not medically serious [35]’( (IASP, 2021)
Diagnosis
Initial assessment of back pain consists of a history and physical examination. Important characterizing features of back pain include location, duration, severity, history of prior back pain and possible trauma. Other important components of the patient history include age, physical trauma, prior history of cancer, fever, weight loss, urinary incontinence, progressive weakness or expanding sensory changes, which can indicate a medically urgent condition.Physical examination of the back should assess for posture and deformities. Pain elicited by palpating certain structures may be helpful in localizing the affected area. A neurologic exam is needed to assess for changes in gait, sensation and motor function.
Determining if there are radicular symptoms, such as pain, numbness or weakness that radiate down limbs, is important for differentiating between central and peripheral causes of back pain. The straight leg test is a maneuver used to determine the presence of lumbosacral radiculopathy, which occurs when there is irritation in the nerve root that causes neurologic symptoms such as numbness and tingling. Non-radicular back pain is most commonly caused by injury to the spinal muscles or ligaments, degenerative spinal disease or a herniated disc. Disc herniation and foraminal stenosis are the most common causes of radiculopathy.Imaging of the spine and laboratory tests is not recommended during the acute phase. This assumes that there is no reason to expect that the patient has an underlying problem. In most cases, the pain subsides naturally after several weeks. People who seek diagnosis through imaging are typically less likely to receive a better outcome than are those who wait for the condition to resolve.
Imaging
Magnetic resonance imaging (MRI) is the preferred modality for the evaluation of back pain and visualization of bone, soft tissue, nerves and ligaments. X-rays are a less costly initial option offered to patients with a low clinical suspicion of infection or malignancy, and they are combined with laboratory studies for interpretation.
Imaging is not needed for the majority of patients with back pain. In cases of acute back pain, MRI is recommended for those with major risk factors or clinical suspicion of cancer, spinal infection or severe progressive neurological deficits. For patients with subacute to chronic back pain, MRI is recommended if minor risk factors exist for cancer, ankylosing spondylitis or vertebral compression fracture, or if significant trauma or symptomatic spinal stenosis is present.Early imaging studies during the acute phase do not improve care or prognosis. Imaging findings are not correlated with severity or outcome.
Laboratory studies
Laboratory studies are employed when there are suspicions of autoimmune causes, infection or malignancy. Laboratory testing may include white blood cell (WBC) count, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP).
Elevated ESR could indicate infection, malignancy, chronic disease, inflammation, trauma or tissue ischemia.
Elevated CRP levels are associated with infection.
Red flags
Imaging is not typically needed in the initial diagnosis or treatment of back pain. However, if there are certain "red flag" symptoms present, plain radiographs (X-ray), CT scan or magnetic resonance imaging may be recommended. These red flags include:
History of cancer
Unexplained weight loss
Immunosuppression
Urinary infection
Intravenous drug use
Prolonged use of corticosteroids
Back pain not improved with conservative management
History of significant trauma
Minor fall or heavy lift in a potentially osteoporotic or elderly individual
Acute onset of urinary retention, overflow incontinence, loss of anal sphincter tone, or fecal incontinence
Saddle anesthesia
Global or progressive motor weakness in the lower limbs
Prevention
Moderate-quality evidence exists that suggests that the combination of education and exercise may reduce an individuals risk of developing an episode of low back pain. Lesser-quality evidence points to exercise alone as a possible deterrent to the risk of the condition.
Management
Nonspecific pain
Patients with uncomplicated back pain should be encouraged to remain active and to return to normal activities.
The management goals when treating back pain are to achieve maximal reduction in pain intensity as rapidly as possible, to restore the individuals ability to function in everyday activities, to help the patient cope with residual pain, to assess for side effects of therapy and to facilitate the patients passage through the legal and socioeconomic impediments to recovery. For many, the goal is to keep the pain at a manageable level to progress with rehabilitation, which then can lead to long-term pain relief. Also, for some people the goal is to use nonsurgical therapies to manage the pain and avoid major surgery, while for others surgery may represent the quickest path to pain relief.Not all treatments work for all conditions or for all individuals with the same condition, and many must try several treatment options to determine what works best for them. The present stage of the condition (acute or chronic) is also a determining factor in the choice of treatment. Only a minority of people with back pain (most estimates are 1–10%) require surgery.
Nonmedical
Back pain is generally first treated with nonpharmacological therapy, as it typically resolves without the use of medication. Superficial heat and massage, acupuncture and spinal manipulation therapy may be recommended.
Heat therapy is useful for back spasms or other conditions. A review concluded that heat therapy can reduce symptoms of acute and subacute low-back pain.
Regular activity and gentle stretching exercises is encouraged in uncomplicated back pain and is associated with better long-term outcomes. Physical therapy to strengthen the muscles in the abdomen and around the spine may also be recommended. These exercises are associated with better patient satisfaction, although they have not been shown to provide functional improvement. However, one review found that exercise is effective for chronic back pain but not for acute pain. Exercise should be performed under the supervision of a healthcare professional.
Massage therapy may provide short-term pain relief, but not functional improvement, for those with acute lower back pain. It may also offer short-term pain relief and functional improvement for those with long-term (chronic) and subacute lower pack pain, but this benefit does not appear to be sustained after six months of treatment. There do not appear to be any serious adverse effects associated with massage.
Acupuncture may provide some relief for back pain. However, further research with stronger evidence is needed.
Spinal manipulation appears similar to other recommended treatments.
"Back school" is an intervention that consists of both education and physical exercises. There is no strong evidence supporting the use of back school for treating acute, subacute, or chronic non-specific back pain.
Insoles appear to be an ineffective treatment intervention.
While traction for back pain is often used in combination with other approaches, there appears to be little or no impact on pain intensity, functional status, global improvement or return to work.
Medication
If nonpharmacological measures are ineffective, medication may be administered.
Non-steroidal anti-inflammatory drugs (NSAIDs) are typically attempted first. NSAIDs have been proven more effective than placebo, and are usually more effective than paracetamol (acetaminophen).
Long-term use of opioids has not been tested to determine whether it is effective or safe for treating chronic lower back pain. For severe back pain not relieved by NSAIDs or acetaminophen, opioids may be used. Opioids may not be better than NSAIDs or antidepressants for chronic back pain with regard to pain relief and gain of function.
Skeletal muscle relaxers may also be used. Their short-term use has been proven effective in the relief of acute back pain. However, the evidence of this effect has been disputed, and these medications do have negative side effects.
For patients with nerve root pain and acute radiculopathy, there is evidence that a single dose of steroids, such as dexamethasone, may provide pain relief.
Epidural corticosteroid injection (ESI) is a procedure in which steroid medications are injected into the epidural space. The steroid medications reduce inflammation and thus decrease pain and improve function. ESI has long been used to both diagnose and treat back pain, although recent studies have shown a lack of efficacy in treating low back pain.
Surgery
Surgery for back pain is typically used as a last resort, when serious neurological deficit is evident. A 2009 systematic review of back surgery studies found that, for certain diagnoses, surgery is moderately better than other common treatments, but the benefits of surgery often decline in the long term.Surgery may sometimes be appropriate for people with severe myelopathy or cauda equina syndrome. Causes of neurological deficits can include spinal disc herniation, spinal stenosis, degenerative disc disease, tumor, infection, and spinal hematomas, all of which can impinge on the nerve roots around the spinal cord. There are multiple surgical options to treat back pain, and these options vary depending on the cause of the pain.
When a herniated disc is compressing the nerve roots, hemi- or partial- laminectomy or discectomy may be performed, in which the material compressing on the nerve is removed. A mutli-level laminectomy can be done to widen the spinal canal in the case of spinal stenosis. A foraminotomy or foraminectomy may also be necessary, if the vertebrae are causing significant nerve root compression. A discectomy is performed when the intervertebral disc has herniated or torn. It involves removing the protruding disc, either a portion of it or all of it, that is placing pressure on the nerve root. Total disc replacement can also be performed, in which the source of the pain (the damaged disc) is removed and replaced, while maintaining spinal mobility. When an entire disc is removed (as in discectomy), or when the vertebrae are unstable, spinal fusion surgery may be performed. Spinal fusion is a procedure in which bone grafts and metal hardware is used to fix together two or more vertebrae, thus preventing the bones of the spinal column from compressing on the spinal cord or nerve roots.If infection, such as a spinal epidural abscess, is the source of the back pain, surgery may be indicated when a trial of antibiotics is ineffective. Surgical evacuation of spinal hematoma can also be attempted, if the blood products fail to break down on their own.
Pregnancy
About 50% of women experience low back pain during pregnancy. Some studies have suggested that women who have experienced back pain before pregnancy are at a higher risk of experiencing back pain during pregnancy. It may be severe enough to cause significant pain and disability in as many as one third of pregnant women. Back pain typically begins at approximately 18 weeks of gestation and peaks between 24 and 36 weeks. Approximately 16% of women who experience back pain during pregnancy report continued back pain years after pregnancy, indicating that those with significant back pain are at greater risk of back pain following pregnancy.Biomechanical factors of pregnancy shown to be associated with back pain include increased curvature of the lower back, or lumbar lordosis, to support the added weight on the abdomen. Also, the hormone relaxin is released during pregnancy, which softens the structural tissues in the pelvis and lower back to prepare for vaginal delivery. This softening and increased flexibility of the ligaments and joints in the lower back can result in pain. Back pain in pregnancy is often accompanied by radicular symptoms, suggested to be caused by the baby pressing on the sacral plexus and lumbar plexus in the pelvis.Typical factors aggravating the back pain of pregnancy include standing, sitting, forward bending, lifting and walking |

Temporal arteritis is an inflammatory disease of medium-sized blood vessels that happens especially with advancing age. AAION occurs in about 15-20 percent of patients with temporal arteritis. Damage to the blood vessels supplying the optic nerves leads to insufficient blood supply (ischemia) to the nerve and subsequent optic nerve fiber death. Most cases of AAION result in nearly complete vision loss first to one eye. If the temporal arteritis is left untreated, the fellow eye will likely suffer vision loss as well within 1–2 weeks. Arteritic AION falls under the general category of anterior ischemic optic neuropathy, which also includes non-arteritic AION. AION is considered an eye emergency, immediate treatment is essential to rescue remaining vision.
An exhaustive review article published in March 2009 described the latest information on arteritic and non-arteritic ischemic optic neuropathy, both anterior (A-AION and NA-AION) and posterior (A-PION, NA-PION, and surgical).
Symptoms
There are several constitutional symptoms of temporal arteritis that may aid in diagnosis of AAION such as jaw claudication (spasms of the jaw muscle), scalp tenderness, unintentional weight loss, fatigue, myalgias and loss of appetite |

The child has a normal karyotype of 46, XY, but DNA analysis shows that he has inherited both of his number 15 chromosomes from his father. These findings are most likely to be indicative of which of the following genetic mechanisms? and explain in detail? | This child has features of Angelman syndrome, and the DNA analysis shows uniparental disomy. The Angelman gene encoded on chromosome 15 is subject to genomic imprinting. It is silenced on the paternal chromosome 15, but is active on the maternal chromosome 15. If the child lacks maternal chromosome 15, there is no active Angelman gene in the somatic cells. This gives rise to the abnormalities typical of this disorder. The same effect occurs when there is a deletion of the Angelman gene from the maternal chromosome 15. The other listed options do not occur in uniparental disomy. |

It can cause miscarriage or stillbirth.
It can also cause serious and progressive visual, hearing, motor, cognitive, and other problems in a child.
Most infected infants appear healthy at birth.
They often do not develop symptoms until months, years, or even decades later in life.
Infants with severe congenital toxoplasmosis usually have symptoms at birth or develop symptoms within the first six months of life.
Symptoms may include:
Premature birth — as many as half of infants with congenital toxoplasmosis are born prematurely, abnormally low birth weight, eye damage, jaundice, yellowing of the skin and whites of the eyes, diarrhea, vomiting, anemia, difficulty feeding, swollen lymph nodes, enlarged liver and spleen, macrocephaly, an abnormally large head, microcephaly, an abnormally small head, skin rash, vision problems, hearing loss, motor and developmental delays, hydrocephalus, a buildup of fluid in the skull, intracranial calcifications, evidence of areas of damage to the brain caused by the parasites, seizures, mild to severe mental retardation.

The left ventricle, however, is still normally activated by the left bundle branch. These impulses are then able to travel through the myocardium of the left ventricle to the right ventricle and depolarize the right ventricle this way. As conduction through the myocardium is slower than conduction through the Bundle of His-Purkinje fibres, the QRS complex is seen to be widened. The QRS complex often shows an extra deflection that reflects the rapid depolarisation of the left ventricle followed by the slower depolarisation of the right ventricle.
Incomplete right bundle branch block
Incomplete right bundle branch block (IRBBB) is an conduction abnormality in the right bundle branch block. While a complete RBBB has a QRS duration of 120 ms or more, an incomplete block has a wave duration between 110 and 120 ms |

Ultrasound failed to show any abnormality. The ideal management will be to: and explain in detail? | Ans. b. Finger guided core biopsy (Ref: Schwartz 9/467; Sabiston19/2035-2037; Bailey 26/818, 25/846)Most breast lesions in pregnancy are benign but biopsy should be done to rule out malignancy. Core-needle biopsy with or without ultrasound guidance is a safe and reliable method for obtaining tissue."Fewer than 25% of the breast nodules developing during pregnancy and lactation will be cancerous. Ultrasonography and needle biopsy are used in the diagnosis of these nodules. Open biopsy may be required. Mammography is rarely indicated because of its decreased sensitivity during pregnancy and lactation; however, the fetus can be shielded if mammography is needed. --Schwartz 9/467"Because of the changes in the breast tissue with pregnancy, imaging modalities may be difficult to interpret. If used with appropriate shielding, mammography carries a limited risk to the fetus. Mammography has a high false-negative rate due to the increased density of the fibroglandular breast tissue, however.: so it has limited usefulness in the evaluation of the pregnant patient. Ultrasonography can safely be performed as an initial evaluation or in conjunction with mammography. Ultrasound is able to distinguish solid from cystic lesions in 97% of patients and is helpful in guiding fine-needle aspiration or biopsy Although MRI does not use ionizing radiation, the two main risks to the fetus from the magnetic field and electromagnetic radiation are heating and cavitation. With other reliable imaging modalities available, MRI is not currently recommended for breast imaging in the pregnant patient.

The test is carried out on the milk accepted for pasteurization. It is based on the observation that bacteria growing in milk bring about a decrease in colour impaed to the milk. In conducting the tests definite quantities of methylene blue are added to 10 ml of milk and the sample is held at a uniform temperature of 37 deg C until the blue colour has disappeared. The milk which remains blue the longest is considered to be the best quality milk. The test thus serves as s confirmation of heavy contamination and compared with direct counts of bacteria, it saves time and money. {Reference: Park&;s textbook of community medicine 23 rd edition.

IgM is not transpoed across the placenta; hence, the presence of IgM in the fetus or newborn indicates intrauterine infection. The first immunoglobulin produced in response to an antigen is IgM. after 3 monts of bih class switching is staed and then other class of immunoglobulins are synthesised. IgM is secreted as a pentamer and is composed of five H2L2 units (similar to one IgG unit) and one moleculeof a J chain.. It is the most efficient Because its interaction with antigen can involve all 10 binding sites, it has the highest binding capacity and cross-linking of all the immunoglobulins. Option 2 IgG is the only immunoglobulin class to cross the placenta and therefore is the most abundant immunoglobulinin newborns.( this is not the the first to be synthesised in newborn) |

It is used for a number of diseases including rheumatic disorders such as rheumatoid arthritis and systemic lupus erythematosus, skin diseases such as dermatitis and psoriasis, allergic conditions such as asthma and angioedema, preterm labor to speed the development of the babys lungs, Crohns disease, cancers such as leukemia, and along with fludrocortisone for adrenocortical insufficiency, among others. It can be taken by mouth, injected into a muscle, or applied to the skin topically in cream, lotion, or liquid forms.Serious side effects include an increased risk of infection, muscle weakness, severe allergic reactions, and psychosis. Long-term use may cause adrenal insufficiency. Stopping the medication suddenly following long-term use may be dangerous. The cream commonly results in increased hair growth and skin irritation. Betamethasone belongs to the glucocorticoid class of medication. It is a stereoisomer of dexamethasone, the two compounds differing only in the spatial configuration of the methyl group at position 16 (see steroid nomenclature).Betamethasone was patented in 1958, and approved for medical use in the United States in 1961. The cream and ointment are on the World Health Organizations List of Essential Medicines. It is available as a generic medication. In the United States, the pills and injectable solutions are more expensive than the cream.
Medical uses
Betamethasone is a corticosteroid that is available as a pill, by injection, and as an ointment, cream, lotion, gel, or aerosol (spray) for the skin, and a foam for the scalp. When given by injection, anti-inflammatory effects begin in around two hours and last for seven days.It is used as a topical cream to relieve skin irritation, such as itching and flaking from eczema. It is used as a treatment for local psoriasis, as betamethasone dipropionate and salicylic acid, or as the combination calcipotriol/betamethasone dipropionate. Betamethasone sodium phosphate is used orally and via injection with the same indications as other steroids. Many betamethasone-based pharmaceuticals include the steroid as the valerate ester.
In a randomized controlled trial betamethasone was shown to reduce some of the ataxia (poor coordination) symptoms associated with ataxia telangiectasia (A-T) by 28-31%.Betamethasone is also used to stimulate fetal lung maturation in order to prevent infant respiratory distress syndrome (IRDS) and to decrease the incidence and mortality from intracranial hemorrhage in premature infants.
A cream with 0.05% betamethasone appears effective in treating phimosis in boys, and often averts the need for circumcision. It has replaced circumcision as the preferred treatment method for some physicians in the British National Health Service.
Side effects
Euphoria
Depression
Adrenal suppression
Hypertension
Groupings of fine blood vessels becoming prominent under the skin, petechiae
Excessive hair growth (hypertrichosis)
EcchymosesProlonged use of this medicine on extensive areas of skin, broken or raw skin, skin folds, or underneath airtight dressings may on rare occasions result in enough corticosteroid being absorbed to have side effects on other parts of the body; for example, by causing a decrease in the production of natural hormones by the adrenal glands.
Betamethasone is also used prior to delivery of a preterm baby to help prepare the lungs for breathing. However, because betamethasone crosses the placenta, which is required for its beneficial effects, it may also be associated with complications, such as hypoglycemia and leukocytosis in newborns exposed in utero.
When injected into the epidural space or the spine, it may cause serious side effects like loss of vision, stroke, and paralysis.
Forms
Betamethasone is available in a number of compound forms: betamethasone dipropionate (branded as Diprosone, Diprolene, Celestamine, Procort (in Pakistan), and others), betamethasone sodium phosphate (branded as Bentelan in Italy) and betamethasone valerate (branded as Audavate, Betnovate, Celestone, Fucibet, and others). In the United States and Canada, betamethasone is mixed with clotrimazole and sold as Lotrisone and Lotriderm. It is also available in combination with salicylic acid (branded as Diprosalic) for using in psoriatic skin conditions |

It was patented in 1987 and approved for medical use in 2003. It is available in Japan, South Korea and in India. In the US, it received FDA approval in 2009.Kowa Pharmaceuticals, a subsidiary of Kowa Company, is the owner of the American patent to pitavastatin.
Medical uses
Like the other statins, pitavastatin is indicated for hypercholesterolaemia (elevated cholesterol) and for the prevention of cardiovascular disease.
A 2009 study of the 104-week LIVES trial found pitavastatin increased HDL cholesterol, especially in patients with HDL lower than 40 mg/dL, who had a 24.6% rise, in addition to greatly reducing LDL cholesterol 31.3%. HDL improved in patients who switched from other statins and rose over time. In the 70-month CIRCLE observational study, pitavastatin increased HDL more than atorvastatin.It has neutral or possibly beneficial effects on glucose control |

A: Hypokalemic hyponatremic alkalosis The vomiting of hydrochloric acid results in hypochloraemic alkalosis but, initially sodium and potassium levels may be relatively normal, but later on bicarbonate is excreted along with sodium and so, with time, the patient becomes progressively hyponatremic and more profoundly dehydrated. Because of dehydration, a phase of sodium retention follows and potassium and hydrogen are excreted in preference. This results in the urine becoming paradoxically acidic and hypokalemia ensues |
