A child attending classes in a preschool is noted by his teacher to have several skin lesions on his arms. The lesions are pustular in appearance and some have broken down and are covered with a yellow crust. Which of the following protects the most likely etiologic agent of this child's infection from phagocytosis and provides serologic specificity? | Streptococcus pyogenes, or Group A Streptococcus (GAS), produces a number of virulence factors. The M protein (d) is the organism's most important antiphagocytic factor, and it conveys serologic specificity-over 100 serotypes are now known. In the early stages of growth, the bacteria have hyaluronic acid (b) capsules. This capsule (similar to human hyaluronic acid structure) is rapidly destroyed by the organism's own hyaluronidase. Also known as spreading factor, hyaluronidase plays a role in GAS cellulitis. Erythrogenic toxin (a) is a superantigen produced by some strain of GAS lysogenized by a bacteriophage carrying the toxin gene; it causes the rash of scarlet fever. A second superantigen, streptococcal pyrogenic toxin, causes streptococcal toxic shock syndrome. Streptolysin O (e) an oxygen-labile hemolysin is useful for identification of the organism and is antigenic so antistreptolysin antibodies can be used to diagnosis rheumatic fever, a sequelae of GAS infection. Lipoteichoic acid (c) is a component of the cell wall that is involved in binding of the bacterium to host fibronectin. | 4 | Erythrogenic toxin | Hyaluronic acid | Lipoteichoic acid | M protein | Microbiology | General | 1c08940a-38cf-4615-8775-d996b78e4b63 | single |

A pharma agent wants to introduce vaccine for 1 yr old and see its efficacy. The study design should be ? | Ans. is 'c' i.e., Field trial Experimental epidemiology (Epidemiological Experiments) Experimental epidemiology is also called trial. Broadly speaking, a trial refers to putting something to a test. This allows the term to be used in reference to a test of a treatment for the sick or a test of a preventive measure intended to ave illness, injury or disease. Therefore, the defining feature of an experimental study is its ability to allocate or assign interventions or treatment to experiment unit. In simple words, the study of a treatment (Drugs, surgical intervention) or preventive measure (e.g. vaccination) on living subjects is known as experimental study or trial. Assignment of treatments may be based on Randamization - In randomized controlled trials Non-randmization trails There are following types of experimental trials Clinical trials: Used to evaluate treatment for people who are ill (e.g. a clinical trial of a chemotherapeutic agent) Field trails: Used to evaluate interventions to prevent disease in healthy people (e.g. a field trial of a vaccine). Community trial: Used to evaluate community-wide intervention (e.g. a community trail of the effects of fluoridation of public water supply). Animal Study: When clincial trails are done on animals (instead of human) is called animal study. In an experimental study, the investigator assign individuals in experimental group and reference group and then follows the two groups for the outcome of interests. Therefore, experimental study is prospective study. Before staing any experimental study the approval of ethics committee is required. The poocol of study is submitted to ethics committee and ethics committee gives approval to the studies which are ethical. So, all experimental studies are considered ethical (after taking approval of ethics committee). There are fewer ethical restrains on experimental study in animals than in human. | 3 | Coho study | Clinical trial | Field trial | None | Social & Preventive Medicine | null | 6ce4ac1f-be93-4956-a030-8c1ec6c3c04f | multi |

Insulin deficiency is the main precipitating factor. Diabetic ketoacidosis can occur in persons of all ages, with 14 percent of cases occurring in persons older than 70 years, 23 percent in persons 51 to 70 years of age, 27 percent in persons 30 to 50 years of age, and 36 percent in persons younger than 30 years. The case fatality rate is 1 to 5 percent . Appropriate treatment includes administering intravenous fluids and insulin, and monitoring glucose and electrolyte levels. Cerebral edema is a rare but severe complication that occurs predominantly in children.

A 23-year-old female presents with pelvic pain and is found to have an ovarian mass of the left ovary that measures 3 cm in diameter. Grossly, the mass consists of multiple cystic spaces. Histologically, these cysts are lined by tall columnar epithelium, with some of the cells being ciliated. What is your diagnosis of this ovarian tumor, which histologically recapitulates the histology of the fallopian tubes? | The surface epithelial tumors of the ovary are derived from the surface celomic epithelium, which embryonically gives rise to the Mullerian epithelium. Therefore these ovarian epithelial tumors may recapitulate the histology of organs derived from the Mullerian epithelium. For example, serous ovarian tumors are composed of ciliated columnar serous epithelial cells, which are similar to the lining cells of the fallopian tubes. Endometrioid ovarian tumors are composed of nonciliated columnar cells, which are similar to the lining cells of the endometrium. Mucinous ovarian tumors are composed of mucinous nonciliated columnar cells, which are similar to the epithelial cells of the endocervical glands. Other epithelial ovarian tumors are similar histologically to other organs of the urogenital tract, such as the clear cell ovarian carcinoma and the Brenner tumor. Clear cell carcinoma of the ovary is similar histologically to clear cell carcinoma of the kidney, or more accurately, the clear cell variant of endometrial adenocarcinoma or the glycogen-rich cells associated with pregnancy. The Brenner tumor is similar to the transitional lining of the renal pelvis or bladder.

Based on immune response - On the basis of immune response, antigens can be divided into : - i) T-cell dependent antigens ii) T-cell in dependent antigens i) T-cell dependent antigens Most of the protein antigens are T-cell dependent. Their immune response is dependent on T-cell activation. After exposure, these antigens are presented to T-cells (helper T-cells) by antigen presenting cells. These primed T-cells then secret cytokines that induce B-cells to produce antibody against that paicular antigen. T-cell dependent reaction has memory response, i.e., subsequent exposure to same antigen result in :? a) A more rapid production of antibodies b) Produced in greater amounts c) Produced for a longer period of time. T-cell independent antigens carbohydrate (Polysaccharide) antigens are T- cell independent. Their immune response does not require activation of T-cells. These antigens directly stimulate B-cells without processing by antigen presenting cells. There is no memory response Protein antigen Carbohydrate antigen * More immunogenic * Less immunogenic * T-cell dependent * T-cell independent * No tolerence * Immunological tolerance occurs * Induce Production of all type of antibodies * Induce production of IgM and IgG only * Memory response is seen * No memory response * Require processing by antigen presenting cells. * Do not require processing * Quickly metabolized * Slowly metabolized | 2 | It has lower immunogenicity | Memory response is seen | Cause polyclonal B cell stimulation | Does not require stimulation by T cells | Microbiology | null | f6e61575-9cad-4440-ab4c-f273c31b13ae | multi |

Substrate level phosphorylation is seen in reaction catalyzed by which enzyme of citric acid cycle? | The reaction involves a substrate level phosphorylation whereby a high energy phosphate is generated from the energy trapped in the thioester bond of succinyl CoA. The enzyme is succinate thiokinase (step 5, Fig.18.2). A molecule of GDP is phosphorylated to GTP and succinate is formed. The GTP can be conveed to ATP by reacting with an ADP molecule: GTP + ADP - GDP + ATPRef: DM Vasudevan, Page no: 218 | 2 | Pyruvate kinase | Succinate thiokinase | Phosphoglycerate kinase | All of the above | Biochemistry | Enzymes | e8a897f9-4bd7-487d-9ee7-be26482cb916 | multi |
Rickets is due to -a) Loss of calcium in urineb) Increased mobilisation of calcium from bonec) Decreased absorption of calciumd) Loss of phosphate in Urine | Rickets is a metabolic disorder characterized by deficient mineralization of bone.

The following statements regarding insulin resistance in diabetic patients are true except: | Insulin resistance in diabetic patients has been defined as insulin requirement of more than 2 U/kg/day for control of hyperglycemia or prevention of ketosis for more than 3 days in the absence of any complications. Stressful conditions (when there is excess of glucocorticoids and other hyperglycemic hormones) like trauma, surgery, and infections can oppose insulin action and produce short-term insulin resistance. In few patients, it may be due to development of antibodies of the IgG type to minor contaminants or to some components (e.g. Zinc, protamine, etc.,) added to insulin, hence it is less commonly seen with purer preparations of insulin or with human insulin (huminsulin).
In case the resistance persists, a short-term course with prednisolone (immunosuppressant) may bring down the insulin requirement. | 1 | It is more common with huminsulin | It may occur in the presence of infections | It may be due to antibodies to insulin | Use of glucocorticoids may be useful in severe cases | Pharmacology | null | 6ffef378-d11a-4ab9-b1fc-80c896ffddfb | multi |
