Chauffers fracture involves what ?
|
Chauffeur&;s fracture, also known as Hutchinson fracture, is a type offracture of the forearm, specifically the radial styloid process. The injury is typically caused by compression of the scaphoid bone of the hand against the styloid process of the distal radius.

"French paradox" is -
|
The French paradox is a catchphrase first used in the late 1980s, that summarizes the apparently paradoxical epidemiological observation that French people have a relatively low incidence of coronary hea disease (CHD), while having a diet relatively rich in saturated fats,in apparent contradiction to the widely held belief that the high consumption of such fats is a risk factor for CHD. The paradox is that if the thesis linking saturated fats to CHD is valid, the French ought to have a higher rate of CHD than comparable countries where the per capita consumption of such fats is lower. The French paradox implies two impoant possibilities. The first is that the hypothesis linking saturated fats to CHD is not completely valid (or, at the extreme, is entirely invalid). The second possibility is that the link between saturated fats and CHD is valid, but that some additional factor in the French diet or lifestyle mitigates this risk--presumably with the implication that if this factor can be identified, it can be incorporated into the diet and lifestyle of other countries, with the same lifesaving implications observed in France. Both possibilities have generated considerable media interest, as well as some scientific research. It has also been suggested that the French paradox is an illusion, created in pa by differences in the way that French authorities collect health statistics, as compared to other countries, and in pa by the long-term effects, in the coronary health of French citizens, of changes in dietary patterns which were adopted years earlier. In 1991, Renaud extended his studies in panership with then junior researchers, cardiologist Michel de Lorgeril and dietician Patricia Salen. The three enhanced Renaud's study, with their paper concluding that: a diet based on southwestern Mediterranean cuisine; which is high in omega-3 oils, antioxidants and includes "moderate consumption" of red wine; created lower cases of cancer, myocardial infarction and cardiovascular disease; paly through increasing HDL cholesterol whilst reducing LDL cholesterol Ref Davidson 23rd edition pg 529

A 64-year-old man with heart failure is recently started on 80 mg/day of furosemide. He now feels weak and tired, but notes that his heart failure symptoms have improved.

Hypokalemia results in prolongation of the QU interval. The delayed repolarization in hypokalemia is best expressed at QU rather than QT prolongation since it can be difficult to separate the T wave from the U wave. In severe cases, the ST segments become depressed. Quinidine, even in therapeutic doses, can cause similar ECG findings. This is felt to be a risk factor for ventricular arrhythmias, including Torsades des pointes.

Diagnostic criteria for Bulimia nervosa are all EXCEPT
|
(B) Presence of other psychiatric disorders # BULIMIA NERVOSA (BN) is an eating disorder characterized by eating binges typically followed by efforts to purge calories through self-induced vomiting, laxative and/or diuretic abuse, prolonged fasting, or excessive exercise. Fear of weight gain leads to the characteristic purging behavior, but BN is centered around the practice of binge eating.> The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), describes diagnostic criteria for BN and includes the following:> Recurrent episodes of binge eating, characterized by the following:> Eating an amount of food, in a discrete period of time, that is larger than most people would eat during a similar period of time under similar circumstances.> A perceived lack of control over eating during the episode of binge eating> Recurrent inappropriate compensatory behavior used to prevent weight gain> Occurrence of binge eating and inappropriate compensatory behaviors, on average, at least twice a week for 3 months> Self-evaluation unduly influenced by body shape and weight> Does not occur exclusively during episodes of anorexia nervosa.

All are true about Amoebic liver abscess except: March 2007
|
Ans. B: Alcoholics are susceptible to develop amoebic liver abscess Amebic liver abscess is the most frequent extraintestinal manifestation of Entamoeba histolytica infection. This infection is caused by the protozoa Ehistolytica, which ascends the poal venous system. The right lobe (posterior superior quadrant) of the liver is more commonly affected than the left lobe. This has been attributed to the fact that the right lobe is supplied predominantly by the superior mesenteric vein, whereas the left lobe is supplied by the splenic vein. Histologic Findings of abscess The abscess contains acellular proteinaceous debris and is surrounded by a rim of amebic trophozoites invading tissue. The abscess contains a chocolate-colored fluid that resembles anchovy paste and consists predominantly of necrotic hepatocytes. Complications Pleuropulmonary infection is the most common complication. Cardiac involvement results following the rupture of an abscess involving the left lobe of the liver. It usually is associated with very high moality. Intraperitoneal rupture occurs in 2-7% of patients. Left lobe abscesses are more likely to progress to rupture because of their later clinical presentation. Bacterial superinfection can occur.

A radiologist notes the presence of fine, radiographically dense crystals in the tissues of a knee joint. This patient most likely has which of the following types of ahropathy?
|
Radiographically dense calcium pyrophosphate dihydrate (CPPD) crystals are deposited in cailage and joint soft tissues in pseudogout, which can involve the knees, wrists, elbows, shoulders, or ankles. If the patient is asymptomatic because the deposition is primarily within cailage, the condition is sometimes called chondrocalcinosis. In its more severe form, the joint involvement can clinically resemble rheumatoid ahritis. Neither gonococcal ahritis, osteoahritis, nor rheumatoid ahritis are associated with crystal formation. The monosodium urate crystals deposited in joints in gouty ahritis are not radio-opaque. Ref: Wyatt C., Kemp W.L., Moos P.J., Burns D.K., Brown T.G. (2008). Chapter 19.

von Willebrand disease is a defect of
|
Primary hemostasis: the formation of the platelet plug.Disruption of the endothelium exposes subendothelial von Willebrand factor (vWF) and collagen, which promote platelet adherence and activation. Activation of platelets results in a dramatic shape change as well as the release of secretory granules. Within minutes the secreted products recruit additional platelets, which undergo aggregation to form a primary hemostatic plug.Defects of primary hemostasis (platelet defects or von Willebrand disease) often present with small bleeds in the skin or mucosal membranes. These bleeds typically take the form of petechiae, minute 1 to 2 mm hemorrhages, or purpura, which are slightly larger (>=3 mm) than petechiae. Mucosal bleeding associated with defects in primary hemostasis may take the form of epistaxis (nosebleeds), gastrointestinal bleeding, or excessive menstruation (menorrhagia).Ref: Robbins and Cotran Pathologic; 9th edition; Chapter 4; Hemodynamic Disorders, Thromboembolic Disease, and Shock; Page no: 122

Thiopentone is ultrasho acting barbiturate. Thiopentone does not produce analgesia and may even produce antianalgesia by reducing the pain threshold. Thiopentone has rapid onset of action (within 30 s) due to high lipid solubility and high non ionized fraction (60%). And ultra-sho duration of action (within 20 mins) due to rapid redistribution. Thiopentone does not completely suppress airway responses to laryngoscopy and intubation and may lead to bronchospasm in asthmatics. Thiopentone is cerebro protective: It reduces CSF volume by facilitating its absorption. It decreases CBF and cerebral blood volume, thus lowering intracranial pressure. It also has anticonvulsant propey which is advantageous in neurosurgical patients who are at increased risk of seizures.

Gastric emptying is decreased by all of the following EXCEPT:
|
Acidity of the chyme, hyper- or hypo-osmolarity of the duodenal contents, irritation of the duodenal mucosa, protein or fat breakdown products in duodenum are the factors sensed by the duodenal receptors. Gastric emptying will then be decreased, by a combination of neural and hormonal signals. Neural signals would be enterogastric reflexes in the ENS; they are triggered by the acidic chyme in the duodenum. Hormonal signals would be in the form of CCK, Secretin, G.I.P. released from duodenal mucosa. Fat in the duodenum is very potent inhibitor of gastric emptying; it causes CCK release. Hormonal factors decrease the gastric motility and cause constriction of pyloric sphincter. Other effects include: fundic relaxation, inhibition of antral motor activity. Gastrin, in physiological amounts, is known to increase gastric motility.

Which of the following is a harmful: March 2009
|
Ans. A: Alpha Paicle The radiation one typically encounters is one of four types: alpha radiation, beta radiation, gamma radiation, and X-radiation. Neutron radiation is also encountered in nuclear power plants and high-altitude flight and emitted from some industrial radioactive sources. A Alpha radiation is a heavy, very sho-range paicle and is actually an ejected helium nucleus. Some characteristics of alpha radiation are: Most alpha radiation is not able to penetrate human skin. Alpha-emitting materials can be harmful to humans if the materials are inhaled, swallowed, or absorbed through open wounds. A thin-window Geiger-Mueller (GM) probe can detect the presence of alpha radiation. Instruments cannot detect alpha radiation through even a thin layer of water, dust, paper, or other material, because alpha radiation is not penetrating. Alpha radiation travels only a sho distance (a few inches) in air, but is not an external hazard. Alpha radiation is not able to penetrate clothing. Examples of some alpha emitters: radium, radon, uranium, thorium. Alpha paicle has poor penetration but maximum ionizing power and is most damaging. B. Beta radiation is a light, sho-range paicle and is actually an ejected electron. Some characteristics of beta radiation are: Beta radiation may travel several feet in air and is moderately penetrating. Beta radiation can penetrate human skin to the "germinal layer," where new skin cells are produced. If high levels of beta-emitting contaminants are allowed to remain on the skin for a prolonged period of time, they may cause skin injury. Beta-emitting contaminants may be harmful if deposited internally. Most beta emitters can be detected with a survey instrument and a thin-window GM probe (e.g., "pancake" type). Examples of these difficult-to-detect beta emitters are hydrogen-3 (tritium), carbon-14, and sulfur-35. Clothing provides some protection against beta radiation. Examples of some pure beta emitters: strontium-90, carbon-14, tritium, and sulfur-35. Beta paicle has moderate penetration, moderate ionizing power and is moderate damaging. C. Gamma radiation and X-rays are highly penetrating electromagnetic radiation. Some characteristics of these radiations are: Gamma radiation or X-rays are able to travel many feet in air and many inches in human tissue. They readily penetrate most materials and are sometimes called "penetrating" radiation. X-rays are like gamma rays. X-rays, too, are penetrating radiation. Sealed radioactive sources and machines that emit gamma radiation and X-rays respectively constitute mainly an external hazard to humans. Gamma radiation and X-rays are electromagnetic radiation like visible light, radiowaves, and ultraviolet light. Dense materials are needed for shielding from gamma radiation. Clothing provides little shielding from penetrating radiation, but will prevent contamination of the skin by gamma-emitting radioactive materials. Gamma radiation is easily detected by survey meters with a sodium iodide detector probe. Gamma radiation and/or characteristic x rays frequently accompany the emission of alpha and beta radiation during radioactive decay. Examples of some gamma emitters: iodine-131, cesium-137, cobalt-60, radium-226, and technetium-99m. Gamma paicle are most penetrating, minimum ionizing power and is least damaging

A 42 year old paraplegic woman has a neurogenic bladder and requires an indwelling urinary catheter. She develops a urinary tract infection and is seen by a urologist, who orders abdominal x-rays and an intravenous pyelogram. The radiographic studies demonstrate a very large stone that fills and follows the contours of the renal pelvis. The stone is most likely composed of which of the following?
|
Staghorn calculi, such as described in the question, are associated with infection by urea-splitting bacteria (notably Proteus species) and are composed of magnesium ammonium phosphate (struvite). They are more common in women than men, and are far more common in patients requiring chronic bladder catheterisation. Calcium-containing stones are typically seen in patients with hypercalciuria without hypercalcemia; one-fifth of patients with this type of stone have hyperuricosuria. Cholesterol is found in gallstones, not kidney stones. Cystine stones are rare; they may be seen in patients with cystinuria, an autosomal recessive disorder of amino acid metabolism.

Congenital Cataract Surgery Treatment of choice: Lens aspiration by manual SICS technique or by phaco-emucification technique. Lensectomy can be done in total cataract with retinal detachment or ROP or any congenital retinal condition where lens aspiration can't be done. IOL should be put in every child above 2 yrs of age and even in less than 2 year of age, less than 6 month avoid putting IOL. A unilateral cataract has to be operated asap.(within days) Note- Bilateral dense cataracts-removed early that is within 6 weeks of bih to prevent stimulus deprivation amblyopia.

What is the ideal treatment for a 55-years-female with Simple hyperplasia of the endometrium with Atypia?
|
Management of Atypical Endometrial Hyperplasia:
"Hysterectomy is the best treatment for women at any age with atypical endometrial hyperplasia because the risk of concurrent subclinical invasive disease is high."
Williams Gynae 1st ed p 691
"In presence of atypia, response to progesterone therapy is poor and the relapse rate is high. Nearly one-third of them will progress to cancer and one-fourth may already have associated undiagnosed cancer. In women approaching or post menopause, hysterectomy is a safer choice in those with complex or atypical hyperplasia."
Jeffcoate 7th/ ed p 425
So Remember: Best management of atypical hyperplasia is hysterectomy.
Also, Know Management of Endometrial Hyperplasia:
Management depends on the patient's age and the presence or absence of cytological atypia.
Non-atypical hyperplasia:
Premenopausal women: Progesterone therapy-
options: - Medroxyprogesterone acetate for 21 days a month daily for 3 months.
Progesterone-containing IUCD.
Postmenopausal women
Simple hyperplasia without atypia - Generally followed without therapy.
Complex hyperplasia without atypia - Cyclical/continuous progesterone therapy.
These patients should be followed annually by endometrial biopsy.
Atypical hyperplasia:
The ideal treatment is a hysterectomy
Premenopausal women willing to preserve fertility - High dose progesterone therapy after full information of risk of undiagnosed cancer or progression to cancer. In these cases periodic TVS and endometrial biopsy is necessary.

A 40 year old woman presents with a three day history of irritation, pain, and watery discharge of her left ear. She has just returned from holiday, where she admits to using her towel, aificial nails, and ear buds to try to allete itching in her ear. What is the likely diagnosis?
|
Inflammation of the ear canal with or without infection is the charecteristic of acute otitis externa. If symptoms are recurrent or if they last longer than three months, the condition is classed as chronic otitis externa. Acute otitis externa can also be classified according to its cause. These are split into three main groups: Infective (bacterial, fungal, and viral), Non-infective dermatitis (allergic, eczematous, and irritant), and Mixed infective and non-infective Exacerbating factors include: Warm humid climates, swimming, frequent hair washing (especially if in the bath), and inseion of foreign bodies can introduce bacterial infection and cause local trauma to the ear canal, making infection more likely. Prolonged use of hearing aids may also predispose to infection.

Following anterior dislocation of the shoulder, apt develops weakness of flexion at the elbow and lack of sensation over the lateral aspect forearm; nerve injured is -
|
The most common complication of anterior dislocation of the shoulder is axillary (circumflex) nerve injury.
There is consequent paralysis of the deltoid muscle, with a small area of anaesthesia at the lateral aspect of the upper arm.
However, in this question, the sensation is lost on the lateral aspect of the forearm (not arm). The lateral side of the forearm has sensory supply from the lateral cutaneous nerve of foreign, a branch of musculocutaneous nerve. The musculocutaneous nerve also supplies the biceps brachii (a flexor of elbow joint).
Therefore, musculocutaneous nerve injury will cause sensory loss over the lateral aspect of the forearm with the weakness of flexion at the elbow.
As occasionally other branches of brachial plexus (other than axillary nerve) can also be injured, the answer to this question is a musculocutaneous nerve.

Least common organ affected in blast injury is -
|
Ans. is 'c' ie., Muscles * An explosion is a phenomenon resulting from sudden release of energy which is then dissipated by a blast wave, by translocation of objects, or by the generation of heat.* Injuries in explosion occur due to four factors:-1) Blast or shock wave# When an explosion occurs, the explosive material produces a large volume of gas and releases a large amount of energy. It produces a 'shock wave' which spread concentrically from the site of explosion.# The injuries depend on the enviornment in which blast occurs:-i) Air blast (most common):* Explosion occurs in air. There is barotrauma to airfilled hollow organs. Tympanic membrane (ear drum) is most sensitive and most commonly injured. Lung is the second organ to be injured and is the most commonly injured hollow organ and most common cause of life threatening injury.* Other parts injured are middle ear, cochlea, eyes, bowels, mesentery, omentum and brain. Homogenous solid organs like liver and muscles are usually not affected.ii) Under water blast (explosion under water):* Gastrointestinal tract is injured most commonly. Lungs are also injured.iii) Solid blast:* Explosive is detonated near a rigid/solid structure and wave of energy spreads through it. If people are in contact with that rigid structure, injuries take place.* The injuries are mostly skeletal; fracture of legs and vertebral column are more common. GIT damage is more common than lung.2) Flame or hot gases# Burns or burning of body may occur.3) Flying missiles (debris)# Flying pieces of explosive debris may be driven through air against the skin causing bruises, abrasions, lacerations, and ragged perforations.4) Anoxia# Various gases liberated during explosion may cause anoxia, e.g. carbon monoxide, nitrous oxide, nitric oxide, HCN and SO2

A 58-year-old postmenopausal woman on estrogen replacement complains of recent onset of spotting. A bimanual pelvic examination is unremarkable. Most likely diagnosis?
|
Any postmenopausal woman who has been on unopposed estrogen and who is now experiencing vaginal bleeding is suspect for either endometrial hyperplasia or endometrial cancer. Endometrial hyperplasia is the end result of prolonged estrogenic stimulation of the endometrial mucosa. Morphologic forms of hyperplasia include cystic, adenomatous, and atypical hyperplasia. In cystic hyperplasia (simple hyperplasia), there are large, dilated glands lined by actively mitosing epithelial cells. Adenomatous hyperplasia refers to branching of the glands with papillary infolding or outpouchings (sometimes referred to as complex hyperplasia). Atypical hyperplasia has more glandular crowding and nuclear atypia than the latter condition and has the highest risk for progressing into carcinoma in situ and endometrial carcinoma. Endometrial carcinoma is the most common invasive cancer of the female genital tract. As with endometrial hyperplasia, the risk factors for endometrial cancer primarily relate to hyperestrinism and include obesity, nulliparity, diabetes, hypeension, infeility, breast cancer, low fiber/high fat diet, early menarche or late menopause, and tamoxifen. The most common clinical presentation is vaginal bleeding (90%) in a postmenopausal woman.

VivaxRef: Microbiology by Ananthanarayan and Paniker 8th ed. 1694* Duffy antigen/chemokine receptor (DARC) also known as CD234, is a protein that in humans is encoded by DARC gene.* The Duffy antigen is located on the surface of red blood cells.* The Duffy antigen protein is also the receptor for the human malarial parasites Plasmodium vivax.* Polymorphisms in this gene are the basis of the Duffy blood group system.Clinical Significance of Duffy Antigen* Asthma: There appears to be a correlation with both total IgE levels and asthma and mutations in the Dufly antigen.* Malaria: On erythrocytes the Duffy antigen acts as a receptor for invasion by the human malarial parasites P. vivax and P. knowles.* Duffy negative individuals whose erythrocytes do not express the receptor are believed to be resistant to merozoite invasion.* HIV infection: The absence of the DARC receptor appears to increase the susceptibility to infection by HIV. HIV-1 appears to be able to attach to erythrocytes via DARC* Lung transplantation: The Duffy antigen has been implicated in lung transplantation rejection.* Multiple myeloma: An increased incidence of Duffy antigen has been reported in patients with multiple myeloma compared with healthy controls* Pneumonia: The Duffy antigen is present in the normal pulmonary vascular bed. Its expression is increased in the vascular beds and alveolar septa of the lung parenchyma during suppurative pneumonia.* Prostate cancer: Experimental work has suggested that DARC expression inhibits prostate tumor growth. The reasons for this increased risk are not known.* Sickle cell anemia: Duffy antigen-negative individuals with sickle cell anaemia tend to suffer from more severe organ damage than do those with the Duffy antigen.

Not true about red degeneration of myomas is :
|
Ans. is b i.e. Immediate Surgical intervention is required Lets see each option one by one. Red Degeneration of fibroid commonly occurs during pregnancy. (Option "a" is thus correct) The pathogenesis of fibroid is obscure but the initial change appears to be one of sub acute necrosis which is presembly due to an interference with its blood supply. Some say that aerial or venous thrombosis is the basis of this and the lesion is the result of infarction. (Option "c" is thus correct). Red degeneration should be managed conservatively with bed rest and analgesics to relieve the pain. (option "d" is thus correct) There is no need for surgical intervention.

Fulminant hepatic failure can be caused by
|
The first modern halogenated volatile anesthetic, halothane, was introduced in 1955. Clinical exposure to halothane is associated with two distinct types of hepatic injury. Subclinical hepatotoxicity occurs in 20% of adults who receive halothane. It is characterized by mild postoperative elevations in alanine aminotransferase and aspaate aminotransferase, but is reversible and innocuous. Anaerobic halothane reduction by CYP2A6 to a 2-chloro-1,1,1-trifluoroethyl radical is thought to mediate this mild hepatic injury. The fulminant form of hepatotoxicity, commonly known as halothane hepatitis, is characterized by elevated alanine aminotransferase, aspaate aminotransferase, bilirubin, and alkaline phosphatase levels, massive hepatic necrosis following the administration of halothane. Halothane hepatitis is rare (1 in 5000 to 35,000 administrations in adults), but is fatal in 50% to 75% of these cases. Because of the potential for fatal hepatitis, halothane is no longer used in adult patients in many countries. Halothane hepatitis is caused by a hypersensitivity reaction associated with the oxidative metabolism of halothane. The highly reactive trifluoroacetyl chloride metabolite of halothane oxidation can react with nearby liver proteins. In most patients who developed hepatic necrosis after halothane anesthesia, antibodies against TFA-modified proteins were detected, suggesting that the hepatic damage is linked to an immune response against the modified protein, which acts as a neoantigen. Accordingly, patients who develop halothane hepatitis often have a history of prior exposures to halothane or other volatile anesthetics, together with symptoms suggestive of immune reactivity, such as fever, rash, ahralgia, and eosinophilia. A current hypothesis is that TFA-protein adducts induce a cytotoxic T cell reaction in sensitized individuals, which leads to liver damage. However, the immune responses observed in halothane hepatitis might not mediate liver injury. Ref: Miller's anesthesia 8th edition Ref: Morgan & Mikhail's clinical anesthesiology 6e

HUS is common in children under 2 years of age. (But may also occur in older children).
It usually follows an episode of acute gastroenteritis.
The prodrome is usually of abdominal pain, diarrhoea and vomiting.
Shortly thereafter, signs and symptoms of acute hemolytic anaemia, thrombocytopenia and acute renal failure ensue.
Sometimes neurological findings also occur (But usually absent and differentiates HUS from TTP).

Oxygen-hemoglobin dissociation curve is shifted to right in the following conditions:
Decrease in partial pressure of oxygen.
Increase in partial pressure of carbon dioxide (Bohr effect).
Increase in hydrogen ion concentration and decrease in pH (acidity).
Increased body temperature.
Excess of 2,3-diphosphoglycerate (DPG) in RBC. It is also called 2,3-biphosphoglycerate (BPG). DPG is a byproduct in Embden-Meyer-hof pathway of carbohydrate metabolism. It combines with β-chains of hemoglobin. In conditions like muscular exercise and in high attitude, the DPG increases in RBC. So, the oxygen-hemoglobin dissociation curve shifts to right to a great extent.
