The right atrium chronic overload is indicated by a P wave of more than:
|
Ans. a. 2.5 mm (Ref: Harrison 19/e p1453, 18/e p1832; Marc Gertsch's The ECG; A Two-Step Approach to Diagnosis';Ch-4)The right atrium chronic overload is indicated by a P wave of more than 2.5 mm."Normal atrial depolarization vector is oriented downward and towards the subject's left, reflecting the spread of depolarization from the sinus node to the right and then the left atrial myocardium. This vector points toward the positive pole of lead II and toward the negative pole of lead aVR. Normal P wave is less than 2.5 mm in lead II. If it is more than 2.5 mm, this indicate right atrial overload."- Harrison 19/e p1453, 18/e p1832Right Atrial Enlargement (P Pulmonale): Peaked, tall and narrow P waves in leads II, III and aVF in lung disease are called 'P pulmonale'. The presence of P pulmonale is taken as P wave of more than 2.5 mm in leads, II, III and aVF. Though many factors such as verticalization of the heart, increased residual volume and impaired lung function have been reported to be correlated with these changes in the P wave, right atrial overload (right atrial enlargement or increased right atrial pressure or both) is still thought to be responsible for P pulmonale in lung disease."- Maeda S, Katsura H. Chida K. Imai T. Kuboki K. Watanabe C, Kida K. Ohkawa S, Matsushita S, Ueda K and Kuramoto K. Lack of correlation between P pulmonale and right atrial overload in chronic obstructive airways disease. Br Heart J. 1991; 65:132-6."Right Atrial Enlargement (P Pulmonale): As the activation of the right atrium begins earlier than that of the left atrium, an increase of the right atrial (RA) vector does not prolong the P duration. P pulmonale is characterized by tall and sometimes pointed P waves in leads II, aVF and III. The amplitude of the P waves is 2.5 mm in at least one of these leads. In the opposite 'lead aVL, the P wave is completely negative. The P wave may be higher than normal and pointed in leads V1/V2 rarely in the other precordial leads."- Marc Gertsch's 'The ECG: A Two-Step Approach to Diagnosis';- Ch-4

Exposure to darkness leads to increased melatonin secretion. It is brought about by:
|
Ans. is 'b' i.e. increasing the serotonin N-acetyl transferase Ref Ganong 21st/e p 468, 20th/e p448First let's see the synthesis of melatonin from serotoninSerotonin| N. Acetyl transferase + Acetyl CoA N-Acetyl serotonin|Hydroxy indole - 0 methyl transferase + S-Adenosylmethionine Melatonin (N-acetyl-5-methoxytryptamine)Regulation of Melatonin SecretionIn humans and all other species studied to date, melatonin synthesis and secretion are increased during the dark period of the day and maintained at a low level during the day-light hours.The remarkable diurnal variation in secretion is brought about by training of the hypothalamus to the light-dark cycle via retino-hypothalamic nervesThe hypothalamus in turn cause norepinephrine secretion by the postganglionic sympathetic nerves (nervi conarii) that innervate the pineal glandThe norepinephrine acts via b adrenergic receptors in the pineal gland to increase intracellular cAMP, and the cAMP in turn produced a marked increase in N-acetyltransferase activity. This results in increased melatonin synthesis and secretionExposure to darkness|Retino hypothalamic fibres| supra chiasmatic nuclei in hypothalamus|Preganglionic sympathetic neurons in spinal cord| postganglionic sympatheticnerves (nervi conarii) arising in superior cervical ganglion|| norepinephrine secretion in pineal gland|| intracellular cAMP ||N-Acetyltransferase activity|| Hydroxyindole - O methyl transferase activity|| Melatonin

The patient has a thoracic outlet syndrome (TOS), which is an abnormal compression of the aeries, veins, or nerves in the neck. TOS is more common in adults than in children, and may occur in either sex. The compression may be caused by a cervical rib, the scalenus anticus muscle, or positional changes. The diagnosis is confirmed with an aeriogram. Nerve conduction studies do not distinguish TOS from cervical disc disease, since the nerves are also involved in TOS.

Comment on the diagnosis of this patient with hypokalemic periodic paralysis.
|
Ans. (c) Grave's disease.* Thyrotoxicosis is sometimes associated with a form of hypokalemic periodic paralysis; this disorder is particularly common in Asian males with thyrotoxicosis.* Lid retraction, causing a staring appearance, can occur in any form of thyrotoxicosis and is the result of sympathetic overactivity.* However, Graves' disease is associated with specific eye signs that comprise Graves' ophthalmopathy* Many scoring systems have been used to gauge the extent and activity of the orbital changes in Graves' disease. The "NO SPECS" scheme is an acronym derived from the following eye changes:0 = No signs or symptoms1 = Only signs (lid retraction or lag), no symptoms2 = Soft-tissue involvement (periorbital edema)3 = Proptosis (>22 mm)4 = Extraocular-muscle involvement (diplopia)5 = Corneal involvement6 = Sight loss

Metacarpophalangeal joints are most commonly affected in: March 2005
|
Ans. C: Rheumatoid Ahritis RA is characterized by diffuse cailage loss and erosion of bone and cailage. It stas in the synol membrane, with the initial processes of edema, neovascularization, and hyperplasia of the synol lining. Proliferation of synoviocytes and macrophages causes thickening of the synol lining and, together with lymphocytes, plasma cells, and mast cells, develops into pannus. Pannus is a sheet of invasive cellular tissue that is continuous with the synol lining. As a result of the higher propoion of synoviocytes and macrophages, pannus causes erosion of bone and cailage at the margin of joints. In the hands, the metacarpophalangeal (MCP), proximal interphalangeal (PIP), and thumb interphalangeal (IP) joints are most frequently involved. The distal interphalangeal (DIP) joints are involved only in the presence of a coexisting MCP or PIP disease. Tenosynovitis of the flexor tendons causes a reduction in finger flexion and grip strength. Nodular thickening in the tendon sheath may also produce a trigger finger. In osteoahritis and psoriatic ahritis, DIP is commonly involved.

A 25-year-old woman complains of low-grade fever, fatigue, and persistent rash over her nose and upper chest. She also notes pain in her knees and elbows. A skin biopsy shows dermal inflammation and granular deposits of IgG and C3 complement along the basement membrane at the epidermal/dermal junction. Urinalysis reveals microscopic hematuria and proteinuria. The ANA is positive. The development of thromboembolic complications (e.g., deep venous thrombosis) in this patient is commonly associated with elevated serum levels of antibodies to which of the following antigens?
|
1/3rd of patients with SLE possess elevated concentrations of anti-phospholipid antibodies. It predisposes these patients to thromboembolic complications (stroke, pulmonary embolism, deep venous thrombosis, and poal vein thrombosis). The clinical course of SLE is highly variable and typically exhibits exacerbations and remissions. The overall 10-year survival rate approaches 90%(Because of early detection & management). -Antibodies against clotting factors (choice C) or fibrinolytic enzymes (choice D) are not involved in the clotting tendency associated with SLE.

A first year psychiatric resident is interviewing a patient in psychiatry ward. On asking any question, patient starts giving long details and to the point that listener may get bored, but eventually patient answers the question. Which of the following abnormality the resident could find in this patient?
|
Ans. D. CircumstantialityCircumstantiality is indirect speech that is delayed in reaching the point but eventually gets there. Circumstantiality is characterized by an overinclusion of details. Verbigeration is a meaningless repetition of specific words or phrases. Blocking is an abrupt interruption in the train of thinking before a thought or idea is finished. After a brief pause, the person indicates no recall of what was being said or what was going to be said. It is also known as thought deprivation. Tangentiality is the inability to have a goal-directed association of thoughts. The patient never gets from the desired point to the desired goal. Word salad is an incoherent mixture of words and phrases.

Tzank smear in a case of pemphigus vulgaris shows
|
Tzanck smear is a very simple and rapid technique. For viral infections, samples should be taken from a fresh vesicle.The vesicle should be unroofed or the crust removed, and the base scraped with a scalpel or the edge of a spatula. The material is transferred to a glass slide.In the case of blistering disorders, the intact roof of a blister is opened along one side, folded back and the floor gently scraped. The material thus obtained is smeared onto a microscopic slide, allowed to air dry, and stained with Giemsa stain. Pemphigus vulgaris: It reveals multiple acantholytic cells (Tzanck cells). A typical Tzanck cell is a large round keratinocyte with a hyperophic nucleus, hazy or absent nucleoli, and abundant basophilic cytoplasm. The basophilic staining is deeper peripherally on the cell membrane ("mourning edged" cells) due to the cytoplasm's tendency to get condensed at the periphery, leading to a perinuclear halo. Herpes simplex, varicella, herpes zoster: multinucleated syncytial giant cells contain multiple nuclei Molluscum contagiosum: basophilic intracytoplasmic molluscum bodies (Henderson-Patterson bodies), the largest known inclusion bodies (30-35 m). Vaccinia, orf, milker's nodules and variola:[ eosinophilic cytoplasmic inclusion called a "Guarnieri body", Leishmaniasis:Cytology is very useful in detecting Leishman-Donovan (LD) bodies in early, untreated patients of leishmaniasis.

The most common type of Rhabdomyosarcoma is
|
Rhabdomyosarcoma, the most common soft-tissue sarcoma of childhood and adolescence, usually appears before age 20. It may arise in any anatomic location, but most occur in the head and neck or genitourinary tract, where there is little if any skeletal muscle as a normal constituent. Rhabdomyosarcoma is histologically sub classified into embryonal, alveolar, and pleomorphic variants. The rhabdomyoblast—the diagnostic cell in all types—contains eccentric eosinophilic granular cytoplasm rich in thick and thin filaments. Rhabdomyoblasts may be round or elongate; the latter are known as tadpole or strap cells, and may contain cross-striations visible by light microscopy.
Embryonal rhabdomyosarcoma is the most common type, accounting for 60% of rhabdomyosarcomas. It includes the sarcoma botryoides as well as spindle cell and anaplasticvariants. The tumor occurs in children younger than 10 years of age and typically arises in the nasal cavity, orbit, middle ear, prostate, and paratesticular region. This variant of rhabdomyosarcoma commonly has parental isodisomy of chromosome 11p15.5, which leads to overexpression of the imprinted IGFII gene. The sarcoma botryoides subtype develops in the walls of hollow, mucosal-lined structures, such as the nasopharynx, common bile duct, bladder, and vagina. Where the tumors abut the mucosa of an organ, they form a submucosal zone of hypercellularity called the cambium layer.

Hysterectomy when done through broad ligament causes injury to?

Adams Hillard page 582Ureter lies in the pararectal space in the medial leaf of broad ligament in pelvis, hence when dissecting through it during hysterectomy, its liable to get injured."During vaginal hysterectomy, the ureter can be traumatized at its entry point at the trigone""Uterine artery ligation consists of placing a no. 1 absorbable suture 2 to 3 cm medial to the uterine vessels through the myometrium and then through an avascular space in the broad ligament. To avoid injury to the ureter, it is important not to go too far lateral in the avascular space"Urinary injuries during hysterectomy:Urinary injuries during laparoscopy have a similar rate to open procedures (0.02-1.7%). Bladder injuries are more common than ureteral injuries and are recognized more frequently intraoperatively, About two-thirds of urinary injuries occur during laparoscopic-assisted vaginal hysterectomy.The most common sites of ureter injury during gynaecological surgeries:Where the ureters enters the pelvis, near the pelvic brim, during ligation of ovarian vesselsWhere the ureter crosses medial to the bifurcation of the iliac vessels during pelvic lymph node dissection3. Where the ureter crosses under the uterine vessels at the level of the broad ligament during ligation of the uterine vessels during hysterectomy

The most useful incision in the operating room for patients with penetrating pericardium injury is:
|
The subxyphoid incision is useful for determining if there is blood in the pericardium and if there is an intracardiac injury; however, exposure is extremely limited, and definitive repair can rarely be performed through the incision. Left (or right) anterior thoracotomy is easily performed, especially in the emergency room, and gives adequate exposure to certain areas of the heart. However, each has significant limitations in exposure. Either may be extended across the thoracotomy into the other side of the chest, thus producing a bilateral anterior thoracotomy. Exposure is excellent through this incision, and most injuries can be satisfactorily repaired through this approach. Most cardiac operations today are performed through median sternotomy incisions. If the patient is in the operating room, this incision is easily performed and always provides excellent exposure for all areas of the heart.

A study of persons developing skin lesions following sun exposure is conducted. The lesions are not found on skin protected from ultraviolet light. Biopsies of involved skin show immunoglobulin G deposition along the dermal-epidermal junction, along with vacuolization of the basal layer and a perivascular lymphocytic infiltrate. No other organ involvement is present. Which of the following diseases do these patients most likely have?
|
The more benign discoid lupus involves just skin, unlike systemic lupus erythematosus, but is still a form of type III hypersensitivity with antigen-antibody complex deposition along the basement membrane of the epidermis. The other listed options are not associated with sun exposure. Bullous pemphigoid lesions occur at the dermal-epidermal junction from antibody deposition targeting type XVII collagen as a component of hemidesmosomes. Dermatitis herpetiformis associated with celiac disease has IgA antibodies deposited at tips of dermal papillae. Dysplastic nevi develop in relation to mutations in genes encoding for growth control proteins. A toxic epidermal necrolysis is a severe form of erythema multiforme mediated by cytotoxic CD8+ cells targeting epidermal basal cells. Early lesions of discoid lupus erythematosus appear as well-demarcated scaly purple macules or papules and later expand into discoid plaques. Microscopically there is basal vacuolar degeneration, areas of epidermal atrophy, acanthosis, keratotic follicular plugging, basement membrane thickening, and superficial and deep perivascular lymphocytic infiltrate.

What is the normal cardiothoracic ratio in children?
|
"The cardiac silhouette occupies 50-55% of the chest width. Cardiomegaly is present when the cardiothoracic (CT) ratio is more than 55%".The CTR is measured on a PA chest x-ray and is the ratio of maximal horizontal cardiac diameter to maximal horizontal thoracic diameter (inner edge of ribs/edge of pleura). A normal measurement should be <0.5(50%).(Refer: Nelson's Textbook of Pediatrics, SAE, 1st edition, pg no. 2170)

A patient has multiple, pearly papules on the face. Biopsy shows a malignant tumor. Which of the following features would most likely be seen on microscopic examination?
|
The malignant skin tumor that forms "pearly papules" on sun-exposed skin is basal cell carcinoma. A characteristic feature of this tumor is palisading of the basal cell-like nuclei at the edge of clusters of cells penetrating into the dermis. Basal cell carcinomas almost never metastasize, but can be very locally destructive, and resection of large ones on the face may produce disfiguring scars. Viral cytoplasmic inclusions are a feature of the infectious lesion molluscum contagiosum. Keratin pearls are a feature of squamous cell carcinoma. Melanin and S-100 positivity with immunohistochemical stains are features of melanoma Ref: Robbins Basic Pathology, 8th Ed, page 852-855

Given technique is called as:
|
Crown-Down Technique
Numerous modifications of the original step-down technique have been introduced, including the description of the crown-down technique. The more typical step-down technique includes the use of a stainless steel K-file exploring the apical constriction and establishing working length.
In contrast, a crown-down technique relies more on coronal flaring and then determination of the working length later in the procedure.
The more typical crown-down, or double-flare technique consisted of an exploratory action with a small file, a crown-down portion with K-files of descending sizes, and an apical enlargement to size #40 or similar. The original technique included stepping back in 1-mm increments with ascending file sizes and frequent recapitulations with a small K-file and copious irrigation. It is further emphasized that significant wall contact should be avoided in the crown-down phase to reduce hydrostatic pressure and the possibility of blockage. Several studies demonstrated more centered preparations in teeth with curved root canals shaped with a modified double-flare technique and Flex-R files compared to shapes prepared with K-files and step-back technique.
A double-flare technique was also suggested for ProFile rotary instruments.

Ref: Textbook of pathology (Harash mohan)6th edition, page no.478 Just as there is clinical definition, there is histologic definition of chronic bronchitis by increased Reid index. Reid index is the ratio between thickness of the submucosal mucus glands (i.e. hyperophy and hyperplasia) in the cailage-containing large airways to that of the total bronchial wall . The increase in thickness can be quantitatively assessed by micrometer lens. The bronchial epithelium may show squamous metaplasia and dysplasia. There is little chronic inflammatory cell infiltrate. The non-cailage containing small airways show goblet cell hyperplasia and intraluminal and peribronchial fibrosis.

An 18-year-old woman has eaten homemade preserves. Eighteen hours later, she develops diplopia, dysarthria, and dysphagia. Which of the following is the most likely causative organism?
|
The incubation period of C. botulinum toxin is 18-36 hours but ranges from a few hours to days. There are no sensory symptoms. Foodborne botulinum is associated primarily with home-canned food. Severe foodborne botulinum can produce diplopia, dysarthria, and dysphagia; weakness then can progress rapidly to involve the neck, arms, thorax, and legs. There is usually no fever. Nausea, vomiting, and abdominal pain can precede the paralysis or come afterward.

Anteversion of uterus is maintained by
|
(D) Round ligaments[?]POSITIONS OF UTERUS:Anteversion of uterus: Long axis of uterus is bent forward on long axis of vagina, In most women.Also, long axis of body of uterus is bent forward at level of internal as with long axis of cervix (anteflexion of uterus). Thus, in erect position and with bladder empty, uterus lies in an almost horizontal plane.Fundus and body of uterus are bent backward on vagina so that they lie in rectouterine pouch (pouch of Douglas). Uterus is therefore retroverted. If body of the uterus is, in addition, bent backward on cervix, it is also retroflexed.Angle of Anteflexion is 125degStructures assist in keeping the uterus in position:Sustainer structures: Urogenital diaphragm, Levator ani muscle, Perineal bodySuspensory Structures:Pubocervical ligament, Cardinal ligament (parametrium)Uterosacral ligamentRound ligament of UterusStructures assist in keeping the uterus in Antever- s ion-anteflexion:Cardinal ligament (parametrium):Supports Anteversion, the uterine angle between cervix & body.-Between Vagina & CervixRound Ligament of Uterus:Maintains Anteflexion of the uterus (a position where the fundus of the uterus leans ventrally).-During Pregnancy it gives support to the anteversion as well.Angle of Anteversion 90deg: Maintained by Round & uterosacral ligaments.It has even more significant role during pregnancy. When the uterus grows during pregnancy, the round ligaments can stretch causing pain.#. Position:!. Non pregnant uterus is within the pelvis.!. It is anteverted & anteflexed in position.!. Long axis of cervix is bent on long axis of vagina this is called Anteversion.!. Body of uterus is bent forwards over cervix at the isthmus and is known as Anteflexion.#. Pubocervical ligament:!.
