One common mode of entry for the microorganisms is into an area of periapical inflammation by way of the blood stream; an anachoretic effect.
It is conceivable also that these microorganisms may enter the periapical tissues by direct immigration through the pulp chamber and root canal of a tooth with an open cavity. The lesion produced is essentially a tuberculous periapical granuloma or tuberculoma. These lesions were usually painful and sometimes involve a considerable amount of bone by relatively rapid extension.

8bcfe52e-721e-419b-b49e-3dc053045196 | Clinical features of rheumatic fever are all except- | Cardiomegaly | Joint pains | ST segment elevation | Increased PR interval | 0 | multi | Ref: R Alagappan - Manual of Practical Medicine 4th Edition.pg no:146-147 Rheumatic Fever Acute, recurrent, inflammatory disease, mainly of children (aged 5-15 years), typically occurring 1-5 weeks after group A streptococcal infection. Pathophysiology 1. Cross reactivity of host antistreptococcal antibodies to cardiac antigens 2. Microbe initiated autoimmune reactivity. Jones Criteria for Diagnosis of Rheumatic Fever Major Criteria Carditis Pancarditis, seen in 50-60% of patients, develops within the first 2 weeks of rheumatic fever. Pericarditis is evidenced by presence of a pericardial rub, myocarditis by tachycardia, soft S1, presence of S3 and CCF and endocarditis by the presence of Carey-Coombs' murmur (mitral diastolic murmur). Ahritis (60-75%) Flitting and fleeting type of polyahritis involving large joints with no residual deformity is seen in 60-75% of patients and occurs early in rheumatic fever. Jaccod's ahritis: Ulnar detion of 4th and 5th finger with flexion at metacarpophalangeal joints is the only residual deformity seen in rheumatic polyahritis. Subcutaneous Nodules Non-tender nodules are seen over bony prominences like elbows, shin, occiput, spine in 3-5% of patients and occur 3-6 weeks after onset of rheumatic fever. Patients who have subcutaneous nodules almost always have carditis. Erythema Marginatum (< 5% and evanescent) Macular lesions with an erythematous rim and central clearing in a bathing suit distribution are seen in < 5% of patients and occur early in rheumatic fever. Chorea (Sydenham's Chorea) (2-30%) A neurological disorder with rapid, involuntary and purposeless non-repetitive movements with a self limiting course of 2-6 weeks is more common in females and is a late manifestation of rheumatic fever. Minor Criteria Clinical 1. Fever 2. Ahralgia 3. Previous history of rheumatic fever or rheumatic hea disease. Laboratory 1. Acute phase reactants (leucocytosis, raised ESR, C-reactive protein) 2. Prolonged PR interval in ECG (> 0.2 sec). WHO Criteria Jones major and pa of the minor criteria except prior history of rheumatic fever/rheumatic hea disease and C-reactive protein. Essential Criteria Evidence for recent streptococcal infection as evidenced by: 1. Increase in ASO titre a. > 333 Todd units (in children) b. > 250 Todd units (in adults). 2. Positive throat culture for streptococcal infection. 3. Recent history of scarlet fever. Two major (or) one major and two minor criteria, in the presence of essential criteria, is required to diagnose Acute Rheumatic Fever. A Positive Rheumatic Fever history is usually elicited in only 50% of patient with Rheumatic Hea Disease. Valve Involvement in Rheumatic Hea Disease Mitral valve alone 50% Aoic valve alone 15-20% Mitral and Aoic valves together 35-40% Mitral, Aoic and Tricuspid valves 2-3% Pulmonary valve is viually never involved. In RHD, mitral valve is most commonly involved followed by involvement of the aoic valve as the pressure gradient across the mitral valve is the greatest, followed by that across the aoic valve. So, the mitral valve is more susceptible to develop pathological changes than the aoic valve. | Medicine | C.V.S |

4b5598b2-e166-4a6b-bd05-9debb46d2d87 | The placenta secretes a hormone that is utilized in the early detection of pregnancy. This hormone is: | Endothelial growth factor (EGF) | Human chorionic gonadotropin (hCG) | Human chorionic somatotropin (HCS) | Relaxin | 1 | single | The synthesis and secretion of hCG begins about day 6 of pregnancy, presumably from the trophoblast cells. Pregnancy tests utilize the measurement of hCG for detection of the embryo. Endothelial growth factor (EGF) is synthesized by the cytotrophoblast cells in the early placenta, then is synthesized by the syncytiotrophoblast cells later (6-8 week old placenta). EGF maintains the trophoblast. Relaxin is synthesized by decidual cells at the time of paurition and acts to "soften" the cervix and pelvic ligaments. IGF act similarly to EGF by stimulating differentiation of the cytotrophoblast cells. HCS is synthesized by syncytiotrophoblast cells and will promote general growth. It is essential in the stimulation of mammary duct proliferation in development of the breast during pregnancy. Ref: Barrett K.E., Barman S.M., Boitano S., Brooks H.L. (2012). Chapter 22.

Usually red blood cells are a standard size of about 6-8 pm in diameter. Certain disorders, however, cause a significant variation in cell size. Higher RDW values indicate greater variation in size. Normal reference range in human red blood cells is 11.5-14.5%. If anemia is observed, RDW test results are often used together with mean corpuscular volume (MCV) results to determine the possible causes of the anemia. It is mainly used to differentiate an anemia of mixed causes from an anemia of a single cause. Deficiencies of Vitamin Bl2 orfolate produce a macrocytic anemia (large cell anemia) in which the RDW is elevated in roughly two- thirds of all cases; however, a varied size distribution of red blood cells is a hallmark of iron deficiency anemia, and as such shows an increased RDW in virtually all cases. In the case of a mixed iron and B!2 deficiency, there will normally be a mix of both large cells and small cells, causing the RDW to be elevated. An elevated RDW (red blood cells of unequal sizes) is known as anisocytosis. An elevation in the RDW is not characteristic of all anemias; anemia of chronic disease,hereditary spherocytosis, acute blood loss, aplastic anemia (anemia resulting from an inability of the bone marrow to produce red blood cells), and certain hereditary hemoglobinopathies (including some cases of thalassemia minor) all may present with a normal RDW* The human erythrocyte is a biconcave disc, 7-2 pm in diameter, and has a thickness of 2-4 pm at the periphery and 1 mm in the centre* More than 90% of the weight of erythrocytes consists of haemoglobin.

This is an example of which of the following types of mutation? | Deletion | Frameshift | Inseion | Missense | 3 | single | Missense mutations are those in which a single base change (point mutation) results in a codon that encodes for a different amino acid residue. The effects of these types of mutations can range from very minor or even undetectable to major, depending on the impoance of the altered residue to protein folding and function. Nonsense mutations are also point mutations in which the affected codon is altered to a stop (nonsense) codon, resulting hi a truncated protein. Frame shift mutations are due to one or two base "pair inseions or deletions such that the reading frame is altered. These mutations generally lead to truncated proteins as well, since in most protein coding regions the unused reading frames contain numerous stop codons. | Biochemistry | null |

Carotid sinus is a little bulge at the root of internal carotid artery, located just above the bifurcation of the common carotid artery. It is innerv ated by the sinus nerve, a branch of glossopharyngeal (IX cranial) nerve. Aortic arch (aortic sinus) also contains mechenoreceptors (stretch receptors) which are similar to carotid sinus receptors. However, their afferent nerve fibers travel in the aortic nerve, a branch of Vagus (X cranial) nerve. o The sinus nerve (from carotid sinus) and aortic nerve/vagal fibers (from aortic sinus) are together called 'Sino- aortic nerves'. They, together, are also refered to as 'Buffer nerves' because they are the afferents of cardiovascular reflexes that buffer abrupt changes in blood pressure. o Baroreceptors are highly sensitive to any change in mean blood pressure. Sinoaortic nerves (buffer nerves) normally discharge rhythmically, synchronous with the pressure fluctuation during systole and diastole. They respond to BP changes between 70 mm Hg and 150 mm Hg. When BP rises, baroreceptors are stimulated and their afferents (through sinoaortic nerves) stimulate nucleus of tractus solitarus (NTS) which inturn inhibits the pressor area of VMC, i.e., Rostral ventrolateral medula (RVLM). This results in decreased sympathetic outflow and therefore decreases in vasomotor tone and vasodilation. Vasodilation brings down the BP. Thereby helping hemostasis. Activated NTS also stimulates nucleus ambiguous (cardioinhibitory center) of medulla, which increases parasympathetic (vagal) output, through vagus, that decreases heart rate. Reduction in heart rate reduces the cardiac output, which also reduces BP. Baroreceptor stimulation also weekly inhibits respiration, o When BP falls, for instance while changing the posture from lying down to standing, reverse change takes place. When a person stands up, his blood is pooled in the veins of lowrer limbs by the effect of gravity. Central venous pressure and venous return decrease, which causes a fall in stroke volume. Hence the systolic BP falls. As a result, the discharge rate of baroreceptors decreases leading to a decrease in the inhibitory' influence on the pressor area of VMC. Hence vasomotor tone increases, leading to vasoconstriction, and consequently an increase in BP. Simultaneously, the nucleus ambiguous of the vagus is also inhibited, increasing the heart rate and consequently stroke volume and eventually BP. Thus fall in BP due to change of posture is very brief (Transient). | Unknown | null |

Like salivary secretion, the stomach actually readies itself to receive the meal before it is actually taken in, during the so-called cephalic phase that can be influenced by food preferences. The gastric secretions arise from glands in the wall of the stomach that drain into its lumen, and also from the surface cells that secrete primarily mucus and bicarbonate to protect the stomach from digesting itself, as well as substances known as trefoil peptides that stabilize the mucus-bicarbonate layer. The glandular secretions of the stomach differ in different regions of the organ. The most characteristic secretions derive from the glands in the fundus or body of the stomach. These contain two distinctive cell types from which the gastric secretions arise: the parietal cells, which secrete hydrochloric acid and intrinsic factor; and the chief cells, which produce pepsinogens and gastric lipase. The acid secreted by parietal cells serves to sterilize the meal and also to begin the hydrolysis of dietary macromolecules. Intrinsic factor is impoant for the later absorption ofvitamin B12 or cobalamin. Pepsinogen is the precursor of pepsin, which initiates protein digestion. Lipase similarly begins the digestion of dietary fats.REF: GANONG&;S REVIEW OF MEDICAL PHYSIOLOGY, KIM BARRETT, HEDDWEN BROOKS, SCOTT BOITANO, SUSAN BARMANTWENTY THIRD EDITIONPAGE NO:432 | Physiology | G.I.T |

Ghrelin is structurally related to motilin and, together, they represent a novel family of gut-brain regulatory peptides. In addition to having a powerful effect on the secretion of growth hormone, ghrelin stimulates energy production and signals directly to the hypothalamic regulatory nuclei that control energy homeostasis. The study of ghrelin has extended our understanding of how growth is controlled and has shown that the stomach is an impoant component of this system. | Physiology | General physiology |

Initially the kidney compensate for metabolic alkalosis by reabsorbing hydrogen and chloride ions in exchange for sodium, potassium and bicarbonate. But gradually as the body stores of sodium and especially potassium become depleted, kidney starts retaining these ions in exchange of hydrogen ions, thus the urine becomes acidic and metabolic alkaline state is further aggravated. | Surgery | null |

He has a generalized erythematous macular rash, and over the next day, develops gangrene of his left leg. Which of the following is the most likely organism? | Corynebacterium diphtheriae | Streptococcus group C | Neisseria gonorrhoeae | Streptococcus group A | 3 | single | Streptococcus group A can cause a toxic shock-like syndrome, and has been increasing in frequency in North America. Streptococcal toxic shock-like syndrome was so named because of its similarity to staphylococcal toxic shock syndrome. The illness includes fever, hypotension, renal impairment, and the respiratory distress syndrome. It is usually caused by strains that produce exotoxin. It may be associated with localized infection as well; the most common associated infection is a soft tissue infection such as necrotizing fasciitis. The mortality is high (up to 30%), usually secondary to shock and respiratory failure. The rapid progression of the disease and its high mortality demand early recognition and aggressive treatment. Management includes fluid resuscitation, pressor agents, mechanical ventilation, antibodies, and, if necrotizing fasciitis is present, surgical debridement. | Medicine | Infection |
