5 year old Boy with something coming out of the anus with pedicle attached to rectal/ anal wall and bright red bleeding- most common diagnosis -
|
Ans. is 'a' i.e., Juvenile rectal Polyp * Juvenile polyps are the most common type of childhood polyp, occurring in up to 1% of preschool children. They are usually solitary polyps found in the rectum which most commonly present with rectal bleeding.* These are hamartomatous polyps, which are usually pedunculated but can be sessile.* "The typical child with a juvenile polyp is 4 to 6 years of age, presents with intermittent painless rectal bleeding with bowel movements."- Rudolph's Pediatrics* Juvenile polyps are usually are not premalignant.* Because the gross appearance of these polyps is identical to adenomatous polyps, these lesions should also be treated by polypectomy.

|
Ref Robbins 9/e p259 Familial (Hereditary) Amyloidosis A variety of familial forms of amyloidosis have been described; most are rare and occur in limited geographic areas. The best-characterized is an autosomal recessive condition called familial Mediterranean fever. This is a febrile disorder characterized by attacks of fever ccompanied by inflammation of serosal surfaces, includ- ing peritoneum, pleura, and synol membrane. This dis- order is encountered largely in persons of Armenian, Sephardic Jewish, and Arabic origins. It is associated with widespread tissue involvement indistinguishable from reactive systemic amyloidosis. The amyloid fibril proteins are made up of AA proteins, suggesting that this form of amyloidosis is related to the recurrent bouts of inflamma- tion that characterize this disease. The gene for familial Mediterranean fever is called pyrin and encodes a protein that is a component of the inflammasome (Chapter 2). Patients have gain-of-function mutations in pyrin that result in constitutive overproduction of the pro- inflammatory cytokine IL-1 and persistent inflammation. In contrast with familial Mediterranean fever, a group of autosomal dominant familial disorders is characterized by deposition of amyloid predominantly in the peripheral and autonomic nerves. These familial amyloidotic poly- neuropathies have been described in kindreds in different pas of the world--for example, in Pougal, Japan, Sweden, and the United States. As mentioned previously, the fibrils in these familial polyneuropathies are made up of mutant forms of transthyretin (ATTRs).

|
There are two large cutaneous veins running up the arm. Both veins take origin from the dorsal venous arch of the hand and run up the lateral and medial sides of the arm. On the medial side (near the 5th digit) there is the basilic vein. On the lateral side (by the thumb), there is the cephalic vein. Since the infection is on the thumb side of the forearm, the correct answer is the cephalic vein. The median antebrachial vein runs down the center of the anterior forearm. The median cubital vein connects the cephalic vein to the basilic vein in the cubital fossa.

A pelvis characterized by an anteroposterior diameter of the inlet greater than the transverse diameter is classified as:
|
Ans. C. AnthropoidBy tradition, pelvis are classified as belonging to one of four major groups. The gynecoid pelvis is the classic female pelvis with a posterior sagittal diameter of the inlet only slightly shorter than the anterior sagittal diameter. In the android pelvis, the posterior sagittal diameter at the inlet is much shorter than the anterior sagittal diameter, limiting the use of the posterior space by the fetal head. In the anthropoid pelvis, the anteroposterior (AP) diameter of the inlet is greater than the transverse diameter, resulting in an oval with large sacrosciatic notches and convergent side walls. Ischial spines are likely to be prominent. The platypelloid pelvis is flattened with a short AP and wide transverse diameter. Wide sacrosciatic notches are common. The pelves of most women do not fall into a pure type and are blends of one or more of the above types.

In transtentorial herniation, a pa of the brain is displaced from the supratentorial to the infratentorial compament through the tentorial opening. It results in all of the following, EXCEPT:
|
The uncus (on the medial aspect of the temporal lobe) herniates under the tentorium cerebelli. The uncus can compress the oculomotor nerve (CN III), compromising the parasympathetic fibers and resulting in ipsilateral pupillary dilation with associated ophthalmoplegia ("down and out"). Cheyne-Stokes respirations are commonly seen with mesial temporal transtentorial herniation. If the uncus is forced fuher medially, it compresses the cerebral peduncle, producing contralateral hemiparesis. After the brain herniates, the patients are decerebrate and comatose, have fixed and dilated pupils, and eye movements are absent. Ref: Cowan J.A., Thompson B. (2010). Chapter 36. Neurosurgery.

Which of the following is the skeletal muscle relaxant of choice in liver and renal disease ?
|
Atracurium is degraded by both pH and temperature dependent Hofmann elimination (autolysis) and by ester hydrolysis; it therefore does not require a dosage adjustment in patients with renal or hepatic failure. However, acidosis and severe hypothermia decrease the rate of drug metabolism and should prompt dose reduction. Mivacurium is a sho-acting benzylisoquinoline with an onset of action comparable to atracurium but with one-third its duration of action, because of rapid hydrolysis by plasma pseudocholinesterase. However, patients with renal or hepatic insufficiency may have depressed pseudocholinesterase activity leading to delayed elimination. Vecuronium is an aminosteroid compound with an intermediate duration of action. It is hepatically metabolized to three active metabolites, all of which are eliminated by the kidney.

Higher secondary attack rate means, more numbers of susceptible contacts are developing the disease after exposure to primary case. So, higher the SAR higher is the communicability (infectiousness) of disease.

(Refer: AK Khurana Comprehensive Ophthalmology, 6th edition, pg no. 248) Phacomorphic glaucoma is an acute secondary angle-closure glaucoma caused by:Intumescent lens i.e., swollen cataractous lens due to rapid maturation of cataract or sometimes following traumatic rupture of the capsule is the main cause of phacomorphic glaucomaAnterior subluxation or dislocation of the lensSpherophakia (congenital small spherical lens) Phacomorphic glaucoma is the term used for secondary angle-closure glaucoma due to lens intumescence. The increase in lens thickness from an advanced cataract, a rapidly intumescent lens, or a traumatic cataract can lead to pupillary block and angle closure.

Tripod fracture is the name given for
|
Zygoma fracture is also known as tripod fracture. Clinical features of zygoma fracture Considerable swelling over zygomatic arch is common and makes clinical diagnosis more difficult. Flattening of malar prominence. Step-deformity of infraorbital margin. Anaesthesia in the distribution of infraorbital nerve. Trismus, due to depression of zygoma on the underlying coronoid process. Oblique palpebral fissure, due to the displacement of lateral palpebral ligament. Restricted ocular movement, due to entrapment of inferior rectus muscle. It may cause diplopia. Periorbital emphysema, due to escape of air from the maxillary sinus on nose-blowing. The mucosa of the maxillary sinus may be lacerated and cause epistaxis on that side. Fracture of the zygoma may or may not be painful to palpation and running a finger along the zygomatic arch may give a feel of a depressed fracture or a small dimple. The cheek may appear flattened compared to symmetry with the opposite side. This may be obvious immediately following trauma or several days later once swelling has subsided.

Peritoneal recesses These are small pockets of the peritoneal cavity enclosed by small, inconstant folds of peritoneum. These are best observed in fetuses and are mostly obliterated in adults. Sometimes they persists to form potential sites for internal hernias and strangulation.
