True Statement about silicosis -a) Produces pleural plaqueb) Associated with tuberculosisc) Lower lobe infiltrationd) Hilar adenopathy
Silicosis Silicosis is a lung disease caused by inhalation of crystalline silicon dioxide (silica). Currently, it is the most prevalent occupational disease in the world. Silicosis is a slowly progressive disease, usually presenting after decades of exposure as slowly progressive nodular fibrosing pneumoconiosis. Silica occurs in both crystalline and amorphous forms but crystalline forms are much more fibrogenic. The crystalline form are quartz, crystobalite. Silicosis is characterized in its early stages by nodules in the upper zones of the lung. As the disease progresses these nodules may coalesce into hard collagenous scars. Fibrotic lesions occur in the hilar lymph node and pleura. Sometimes thin sheets of calcification occur in the lymph nodes and are seen radiographically as egg shell calcification i.e. (calcium surrounding a zone lacking calcification. It the disease continues to progress, expansion and coalescence of lesions produce progressive massive fibrosis. Histologically the lesions of silicosis consists of concentric layers of hyalinized collagen surrounded by a dense capsule of more condensed collagen. Examination of the nodules by polarized microscopy reveals the birefringent silica particles. Silicosis is associated with an increased susceptibility to TB. It is postulated that silicosis results in depression of cell mediated immunity and the crystalline silica may inhibit the ability of pulmonary macrophages to kill phagocytosed mycobacteria. Nodules of silicotuberculosis often display a central zone of caseation.

Retinitis pigmentosa patients doesn't have:-
Not all, but many studies have found that patients with retinitis pigmentosa tend to have lower blood levels of DHA (Docosa Hexaenoic Acid, o3, 22:6), an omega -3 fatty acid found in the photoreceptor cells. ADDITIONAL READING ON DHA: Also known as Cervonic acid. This is having 22 C and 6 double bonds (Docosa means 22, Hexaenoic means 6 double bonds). These days health drinks (bournvita, horlicks) are foified with DHA, as it is impoant for the brain and retina development in infants and children. Decreased amounts lead to increase risk of Retinitis Pigmentosa. DHA is present in high concentration in sperms, retina, cerebral coex. Constant source of DHA is breast milk. Synthesized to a limited extent from a-linolenic acid or obtained directly from fish oils.

Zero order kinetics is followed by all of the following drugs EXCEPT
Zero order (linear) kinetics; The rate of elimination remains constant irrespective of drug concentration, Clearance decreases with increase in concentration, or a constant amount of the drug is eliminated in unit time, e.g. ethyl alcohol, methanol. The elimination of some drugs approaches saturation over the therapeutic range, kinetics changes from first order to zero order at higher doses. As a result plasma concentration increases dispropoionately with an increase in dose, as occurs in case of phenytoin, tolbutamide, theophylline, warfarin, aspirin, digoxin Barbiturates follow first order kinetics.

Capilary Refill time in child with shock is ?
1. Capillary refill time (C) * The accepted upper normal time is < 3 sec. * A study of 469 preterm and term healthy neonates at 1-7 days of age demonstrated significant site and observer variations when C was measured on the chest, forehead, palm, and heel. * C is more reliable when measured on the chest but not the forehead, palm or heel. A positive predictive value of C for SBF was found only when the refill time was over 6 s. When the refill time is this long, the clinician generally does not need to press the skin to know that something is wrong. Press on the finger for five seconds using moderate pressure at an ambient temperature of 20-25 degrees Celsius. A capillary refill time of three seconds or more should be considered abnormal. ... Normal capillary refill time is usually 2 seconds or less. Reference: GHAI Essential pediatrics, 8th edition

A 60-year-old man is hit by a pickup truck and brought to the emergency department with a blood pressure of 70/0 mm Hg. Peritoneal lavage showed no blood in the abdomen. The blood pressure is elevated to 85 systolic following the administration of 2 L of Ringer's lactate. An x-ray showed a pelvic fracture. What is the next step in management?
Early external fixation of the pelvis has been shown to reduce bleeding and mortality in patients in shock consequent to pelvic fractures. An unstable patient should not be sent for a CT scan. Selective angiography with embolization of the bleeding vessel may also be helpful in these patients. Laparotomy usually results in uncontrollable pelvic bleeding.

The most effective buffer system in the blood which is controlled by respiration is:
The bicarbonate buffer system is one of the most effective buffer systems in the body because the amount of dissolved CO2 is controlled by respiration (ie, it is an "open" system). Additional control of the plasma concentration of HCO3- is provided by the kidneys. Additional factors that make the carbonic-acid-bicarbonate system such a good biological buffer: The reaction CO2 + H2O ? H2CO3 proceeds slowly in either direction unless the enzyme carbonic anhydrase is present. There is no carbonic anhydrase in plasma, but there is an abundant supply in red blood cells, spatially confining and controlling the reaction. The presence of hemoglobin in the blood increases the buffering of the system by binding free H+ produced by the hydration of CO2 and allowing for movement of the HCO3- into the plasma.

What is the mechanism of acute rheumatic fever
Cross reactivity with endogenous antigen Acute Rheumatic fever results from immune response to group A streptococci. - The main factor responsible for virulence in infection with streptococcal A group is "M" protein. - The body mounts an immune response against streptococci A organism by producing antibodies directed against the "M" protein. Antibodies directed against the "M" protein of streptococci have been shown to cross react with self antigens in the hea. - The streptococcal M protein and the human myocardium appears to be identical antigenically. - Epitopes present in the cell wall membrane and the A,B,C repeat regions of the "M" protein are immunologically similar to molecules in human myosin. tropomysin, keratin actin, laminin, vimentin. - "This molecular mimicry is the basis for autoimmune response that leads to Acute Rheumatic fever".

Ans. (d) Reticulocyte count(Ref: Robbins 9th/pg 645-648)This is a tricky question as the initial investigation looks like B12 /folate levels, as the patient has macrocytosis.But remember, Macrocytosis can also be seen in hemolytic anemia, as newer RBC precursors released are larger in size.So the initial investigation should be reticulocyte countIf reticulocyte % is low it can be macrocytic anemia & if there is reticulocytosis, then it can be a case of hemolytic anemia.

The earliest immunoglobulin to be synthesized by the fetus is -
Option 1, 3, 4 IgM: IgM is the first immunoglobulin to be synthesized by a neonate in about 20 weeks of age. 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)

Granulomatous inflammation is a characteristic feature of Type IV hypersensitivity reaction against tubercle bacilli. When ceain non degradable antigen such as tubercle antigen is present, the initial perivascular mononuclear cell monocyte infiltrate is replaced by macrophages over a period of 2-3 weeks. The accumulated macrophage then undergo morphological transformation into epithelial like cells and are then referred to as epithelioid cells. A microscopic aggregation of epithelioid cells, usually surrounded by a collar of lymphocytes, is referred to as granuloma. And this pattern of inflammation is called granulomatous inflammation.Ref: Robbins Pathologic Basis of Disease, 6th Edition, Pages 204-6

It can be done in disease involving all or few layers of cornea eg keratoconus, pseudophakic bullous keratopathy, Fuchs endothelial & other dystrophies. An ideal graft size is 7.5 mm; grafts smaller than this may 1/t high astigmatism. Grafts 8.5 mm are prone to postoperative anterior synechiae formation, vascularization and increased intraocular pressure. - PKP has long been the gold standard for treatment of endothelial dysfunction. The limitations of PK include However, because of recent advances & lack of these limitations, endothelial keratoplasty is rapidly gaining popularity. It takes 6 months to many years for the refraction to stabilize 10-15% of patients typically require a hard contact lens for best vision and final mean refractive cylinder of 45D is common PKP incision cuts all corneal nerves, so the inclination to blink and produce tears is reduced postoperatively. This, together with prolonged presence of corneal sutures, increases the risk that ocular surface complications will interfere with recovery. PKP wound never heals back to the full strength of a virgin cornea, so a PKP eye is forever at increased risk of loss from a traumatic injury. Paial Thickness /Lamellar Keratoplasty (LKP) - It is a procedure in which a paial thickess graft of donor tissue is used to provide tectonic stability and /or optical improvement. - It may be of 2 types: anterior LKP and posterior LKP. - In anterior LKP, the transplanted tissue does not include corneal endothelium. This procedure avoids endothelial rejection and thus donor tissue may be obtained from older eyes. Indications for anterior LKP mainly include anterior corneal pathology in which the posterior cornea is unaffected - In deep LKP and posterior LKP, the diseased corneal endothelium is replaced while keeping the anterior corneal surface intact. - Because the donor endothelium is not used, the criteria for anterior LKP are less stringent than those used in PKP; the tissue does not need to be as fresh as that used in PKP. Corneal stroma may be used upto 7 days postmoem (whereas, Posterior LKP has same criteria as PKP) . Endothelial Keratoplasty (EK) i.e. posterior lamellar keratoplasty/ Descemet's Stripping endothelial Keratoplasty involves selective removal of dysfunctional recipient corneal endothelium and replacement with donor tissue consisting of posterior stroma and healthy endothelium. EK is performed through a small incision and spares the majority of host cornea so corneal strength and surface topography are minimally altered & technique is essentially refractive neutral. Fuhermore, corneal innervaton is retained and corneal sutures are not required. So corneal surface complications are minimal. The small incison allows rapid healing and rapid visual recovery after surgery. While fewer patients may achieve 20/20 vision after EK compared with PKP, overall the visual results are more predectible. - DSEK increases corneal thickness because posterior donor stroma is implanted without removal of any recipient stoma. In general, younger patients are likely to achieve better visual acuity after DSEK than older patients (even when have no retinal problems). Whereas PKP was often post phoned until after retirement or at least until visual problems were quite disturbing, EK is now being performed earlier, when visual problems begin to interfere with daily activities, such as reading or driving Infact, it is preferable to perform EK before long standing corneal edema 1/ anterior stromal scarring, because the anterior stroma is not replaced in EK.

Triple negative breast cancer- What is true -
Ans. is 'b' i.e., There are no receptors postitve for ER, PR and HER2 NEU o Triple-negative breast cancer refers to any breast cancer that does not express the genes for estrogen receptor (ER), progesterone receptor (PR) or Her2/neu. This makes it more difficult to treat since most chemotherapies target one of the three receptors, so triple-negative cancers often require combination therapies. Triple negative is sometimes used as a surrogate term for basal-like; however, more detailed classification may provide better guidance for treatment and better estimates for prognosis.o Triple-negative breast cancers comprise a very heterogeneous group of cancers. There are conflicting information over prognosis for the various subtypes but it appears that the Nottingham prognostic index is valid and hence general prognosis is rather similar with other breast cancer of same stage, except that more aggressive treatment is required. Some types of triple-negative breast cancer are known to be more aggressive with poor prognosis, while other types have very similar or better prognosis than hormone receptor positive breast cancers. Pooled data of all triple-negative subtypes suggest that with optimal treatment 20-year survival rates are very close to those of hormone positive cancer.o Triple-negative breast cancers have a relapse pattern that is very different from hormone-positive breast cancers: the risk of relapse is much higher for the first 3-5 years but drops sharply and substantially below that of hormonepositive breast cancers after that. This relapse pattern has been recognized for all types of triple-negative cancers for which sufficient data exists although the absolute relapse and survival rates differ across subtypes

A 67 year old lady is brought in by her 6 children saying that she has gone senile. Six months after her husband's death she has become more religious, spiritual and gives lots of money in donation. She is occupied in too many activities and sleeps less. She now believes that she has a goal to change the society. She does not like being brought to the hospital and is argumentative on being questioned on her doings. The diagnosis is:-
Kindly don't get confused with the fact that the symptoms are following husband's death. Even negative life events can precipitate manic episode. This patient has increased religiosity, overspending, increased activity levels, decreased sleep, new interests and goals and lack of insight. All these symptoms are suggestive of mania.

The most important regulator of serum 1,25 (OH)2 vitamin D concentration is:
A major function of parathyroid hormone is to act as a trophic hormone to regulate the rate of formation of 1,25(OH)2 vitamin D. The mechanism by which parathyroid hormone exerts this effect may be secondary to its effects on phos­phorus metabolism. Other hormones, including prolactin and estrogen, also may playa role in stimulating the production of 1,25(OH)2 vitamin D.

Ans. is 'c' i.e., Nonenzymatic degradation The unique feature of atracurium is inactivation in plasma by spontaneous nonenzymatic degradation (Hofmann elimination) in addition to that by alkaline ester hydrolysis. Consequently its duration of action is not altered in patients with hepatic / renal insufficiency or hypodynamic circulation Preferred muscle relaxant for such patients as well as for neonates and the elderly.o Atracurium is metabolised to laudanosine that is responsible for seizures. It can cause histamine release Hypotension & bronchoconstriction.
