Which of the following is an example of precipitation reaction? | Precipitation is a method for detecting an antigen-antibody reaction. When antigen and antibody combine in the proper propoions, a visible precipitate is formed. Optimum antigen-antibody ratios can be produced by allowing one to diffuse into the other, most commonly through an agar matrix (immunodiffusion). Counterimmunoelectrophoresis (CIE) is a type of precipitation reaction where immunodiffusion carried out in an electrophoretic field. Both the speed and the sensitivity of immunodiffusion are improved by CIE. Ref: Ray C.G., Ryan K.J. (2010). Chapter 4. Principles of Laboratory Diagnosis of Infectious Diseases. In C.G. Ray, K.J.

An orbital tumor has the following characteristics: Retrobulbar location within the muscle cone, well defined capsule, presents with slowly progressive proptosis, easily resectable, occurs most commonly in the 2" to 4th decade. The diagnosis is: | Cavernous hemangioma Cavernous hemangioma is the most common benign, intraconal tumor in adults. Hemangiopericytoma is also retro bulbar intraconal lesion. found in adults but is a rare tumor. Moreover owing to its tendency to invade the adjacent tissues, its margins are less distinct than cavernous hemangioma. Rest 2 options i.e. Dermoid and Capillary hemangiomas are primarily extraconal lesions. Cavernous hemangioma Cavernous hemangioma is the most common orbital vascular tumor in adults. Patients are typically middle aged (2nd to 4th decade) Present with slowly progressive painless proptosis Mostly its intraconal (>80%) but may also be extraconal. Cavernous hetnangiomas possess a distinct fibrous pseudo capsule and therefore on CT and MR appear well defined masses. Cavernous hemangioma is easily resectable as it is: - well encapsulated - does not have a prominent aerial supply (in contrast to capillary hemangioma) Capillary hemangioma Capillary hemangiomas occur primarily in infants. The tumor often increases in size for 6 to 10 months and then gradually involutes. Mostly extraconal, commonly occur in superior nasal quadrant. Capillary hemangiomas in and around the orbit may have an aerial supply from either the external carotid or internal carotid aeries. These tumors are capable of profuse bleeding. On CT and MR these lesions appear fairly well marginated to poorly marginated. Hemangiopericytomas Hemangiopericytomas are rare, slow growing vascular neoplasms that arise from the pericytes of Zimmermann, which normally envelop capillaries. About 50% cases are malignant. On CT and MR the orbital hemangiopericytoma, in contrast to cavernous hemangioma, appear less distint owing to its tendency to invade the surrounding tissues. Angiography may differentiate the tumors from cavernous hemangioma, meningioma, and schwannoma. - Hemangiopericytomas usually have an early florid blush - Cavernous hemangiomas show late minor pooling of contrast, or often appear as avascular masses - Meningiomas may show multiple tumor vessels and a late blush - Schwannomas may show no tumor blush. Dermoid Dermoid and epidermoids are the most frequent development cysts of the orbit. They result from the inclusion of ectodermal elements during closure of the neural tube. The dermoid contains one or more dermal adnexal structures such as sebaceous glands and hair folliclels. Dermoids are extraconal lesions. mostly located at the superior temporal quadrant of the orbit. On CT or MR demonstration offat within the lesion is almost diagnostic of dermoid. | 4 | Hemangiopericytoma | Dermoid | Capillary hemangioma | Cavernous hemangioma | Ophthalmology | null | 17b2a788-0342-4b41-b506-ae1957474ad2 | single |

Following can lead to osteomalacia EXCEPT- | Calcium is the most abundant cation in the body and powerful homeostatic mechanisms control circulating ionised calcium levels . The WHO's dietary guidelines for calcium differ between countries, with higher intakes usually recommended in places with higher fracture prevalence. Between 20% and 30% of calcium in the diet is absorbed, depending on vitamin D status and food source. Calcium requirements depend on phosphorus intakes, with an optimum molar ratio (Ca:P) of 1 : 1. Excessive phosphorus intakes (e.g. 1-1.5 g/day) with a Ca:P of 1 : 3 have been shown to cause hypocalcaemia and secondary hyperparathyroidism Calcium absorption may be impaired in vitamin D deficiency and in malabsorption secondary to small intestinal disease. Calcium deficiency causes impaired bone mineralisation and can lead to osteomalacia in adults.

A 30-year-old man has had cramping abdominal pain and bloody diarrhea for the past 4 days. On physical examination, there is diffuse tenderness on palpation of the abdomen. Bowel sounds are present. There are no masses and no organomegaly. A stool culture is positive for Shigella flexneri. The episode resolves spontaneously within 1 week after onset. Six weeks later, he has increasingly severe lower back pain. Physical examination now shows stiffness of the lumbar spine and tenderness of the sacroiliac joints. He is treated with nonsteroidal anti-inflammatory agents. Two months later, the back pain recurs, and he complains of redness of the right eye and blurred vision. Serologic testing for which of the following is most likely to be positive in this patient? | This patient developed enteritis-associated arthritis affecting the lumbar and sacroiliac joints several weeks after Shigella dysentery. He subsequently developed conjunctivitis and, most likely, uveitis. This symptom complex is a classic representation of a cluster of related disorders called seronegative spondyloarthropathies. This cluster includes ankylosing spondylitis, reactive arthritis, psoriatic arthritis, and enteropathic arthritis (as in this case). A common feature is a very strong association with the HLA-B27 genotype. Despite some similarities with rheumatoid arthritis, these patients invariably have a negative test result for rheumatoid factor. Urethritis caused by Chlamydia trachomatis can trigger reactive arthritis, another form of seronegative spondyloarthropathy. Such infection precedes the onset of arthritis, however. There is no relationship between infection with Borrelia burgdorferi, the causative agent of Lyme disease, and reactive arthritis in individuals testing positive for HLA-B27. Similarly, Epstein-Barr virus infection is not a trigger for these disorders. | 4 | Borrelia burgdorferi | Chlamydia trachomatis | Epstein-Barr virus | HLA-B27 | Pathology | Osteology | 44efcde8-dadc-4ad5-9072-142f27d84768 | single |

In most instances, the periphery of periapical inflammatory lesions is ill defined, showing a gradual transition from the surrounding normal trabecular pattern into the abnormal bone pattern of the lesion. In chronic cases, the new bone formation may result in a very dense sclerotic region of bone, obscuring individual trabeculae.

Sepsis of index finger will spread to? | Ans. a (Thenar).Deep thenar space infection occurs in the potential space between the palmar aponeurosis and the fascia overlying adductor policis, which contains not only the flexor pollicis longus tendon plus the neurovascular (NV) bundles to the thumb, but also the NV bundle on the radial side of the index plus the flexor tendons of the index. Therefore, a deep thenar space infection can involve both the thumb and the index finger.The pollical sheath extends distally almost to its insertion, and that part of the common sheath for the little finger usually does likewise. The ring, middle, and index fingers are provided with digital sheaths that usually extend proximally no further than the necks of their metacarpal bones, leaving a gap of 1 to 3 cm below the common sheath. Hence infection of the synovial sheaths of the thumb or little finger may spread along tendon sheaths readily into the palm and even into the forearm.Also remember:Hypothenar musclesMuscle Origin Insertion InnervationActionAbductor digiti minimi Pisiform}Medial side of}} Abducts little fingerFlexor digiti minimi brevis}Hooks of hamate}proximal phalanxDeep branch of ulnarFlexes little fingerOpponens digiti minimi Front of 5th metacarpal Draws 5th metacarpal forwardPalmaris brevis Medial border of palmar aponeurosis Skin on medial side of hand Superficialbranch of ulnarDeepens hollow of palm & protects ulnar nerve & arteryThenar MusclesMuscles Origin Insertion InnervationActionAbductor pollicis brevis}Flexor ratinaculum}Lateral sesamoid &} Abducts thumb Flexes thumbFlexor pollicis brevis}& tubercle of trapezium}base of proximal phalanx}Recurrent branch of medianRotates 1st metacarpalOpponens pollicis Lateral side of 1st metacarpal- mediallyAdductor pollicis Capitate, trapezoid, base of 2nd metacarpal {oblique head) & front of 3rd metacarpal (transverse head) Medial sesamoid & base of proximal phalanx Deep branch of ulnarAdducts thumb | 1 | Thenar | Mid-palmar | Hypothenar | All of the above | Anatomy | Upper Extremity | 4172a596-6779-4263-94e9-d940ecd9894a | multi |

Most common location of accessory spleen | Accessory spleen, in other words supernumerary spleens, splenunculi, or splenules, results from the failure of fusion of the primordial splenic buds in the dorsal mesogastrium during the fifth week of fetal life. Incidence of accessory spleen in the population is 10%-30% of patients in autopsy series and 16% of patients undergoing contrast enhanced abdominal CT. Although the most common location for an accessory spleen is splenic hilum (75%) and pancreatic tail (25%) , it can occur anywhere in the abdomen including gastrosplenic or splenorenal ligaments, wall of stomach or bowel , greater omentum or the mesentery, and even in the pelvis and scrotum. Accessory spleen usually measures 1 cm in diameter, but its size varies from a few milimeters to centimeters. Also the number of accessory spleens can vary from one to six . Accessory spleens are usually incidentally detected and asymptomatic, but in case of unexpected locations, accessory spleen can be of clinical impoance.

Leaving (or forgetting) an instrument or sponge in the abdomen of the patient during a surgery and closing operation is: | Ans. d (Criminal negligence). (Ref. Textbook of FMT by Parikh 6th ed. 1.46)Contributory negligencea common law defence to a claim or action. It applies to a situation where a plaintiff claimant has, through their own negligence, caused or contributed to the injury they suffered. For example where a pedestrian crosses a road carelessly and is hit by a driver who is also driving carelessly.Comparative negligencea system of apportioning recovery for a tort based on a comparison of the plaintiff's negligence with the defendant's. It contrasts with the doctrine of contributory negligence, which disallows recovery by a plaintiff whose actions in some way, however small, contributed to the tort.Criminal negligencedefined as careless, inattentive, neglectful, willfully blind, or in the case of gross negligence what would have been reckless in any other defendant. For example, leaving (or forgetting) an instrument or sponge in the abdomen of the patient during a surgery and closing the operation contributes to criminal negligence.Corporate manslaughtera term for an act of homicide committed by a company. In general, a legal person is in the same position as a natural person, and may be convicted for committing virtually all offences, under English criminal law.

In a pregnant female, there is decreased requirement of the spinal anaesthetic agent because of all of the following except – | A smaller dose of local anaesthetic is nedded to produce the same level of neuraxial block in pregnant women compared with nonpregnant women.
The causes may be :-
Compression of the inferior vena cava by the pregnant uterus causes "distension or engorgment" of the epidural venous plexus. This decreases the volume of the epidural space and also the volume of the CSF per spinal segment. Therefore a given dose of epidural or intrathecal local anaesthetic will produce a greater degree of demiatomal involvement.
Pregnant women exhibit increase susceptibility to local anaesthetics.
