Nervous System | f96036bf-c381-4797-bf2e-68aebe5329d1 | Ans. a (Middle meningeal artery). (Ref: B & L, Surgery, 25th/ 303).Extradural haematoma (EDH)# It is a neurosurgical emergency. An EDH is nearly always associated with a skull fracture and is more common in young male patients. The skull fracture is asso- ciated with tearing of a meningeal artery and a haematoma accumulates in the space between bone and dura. The most common site is temporal, as the pterion is not only the thinnest part of the skull but also overlies the largest meningeal artery - the middle meningeal.# An EDH may also occur in other regions such as frontal as well as in the posterior fossa. They are not always arte- rial: disruption of a major dural venous sinus can result in an EDH. The force required to sustain a skull fracture can be surprisingly small - a fall from standing or a single blow to the head.# The classical presentation of an EDH, occurring in less than one-third of cases, is initial injury followed by a lucid interval when the patient complains of a headache but is fully alert and orientated with no focal deficit. After minutes or hours a rapid deterioration occurs, with contralateral hemiparesis, reduced conscious level and ipsilateral pupillary dilatation as a result of brain compression and herniation.FEATUREEDH (EXTRADURAL HEMATOMA)SDH (SUBDURAL HEMATOMA)Incidence1-4%10-20%EtiologyLacerated middle meningeal artery/ dural sinus in 70 to 85% cases.Stretching, tearing of bridging cortical veins.AgeAnyOlder peoplefractureSeen in 85-95% cases-LocationBetween skull & dura.95% supratentorialCrosses dural attachments but not sutures.Between dura & arachnoid95% supratentorialCrosses suture but not dural attachmentBilateral5%15%CT- Biconvex (lentiform shape)- 2/3 hyperdense (- 1/3 mixed density)- Displace greywhite interfacea) Acute SDH: Crescentic & hyperdenseb) Subacute SDH: May be nearly isodense with cortex neo-membrane, underlying vessels may enhance.c) Chronic SDH: Hypodense with enhancing membrane.

This is so because action alobe does not amount to guilt unless if is accompanied by a guilty mind. And, a child of that tender age cannot have a guilty mind or criminal intention with which the act is done. This presumption, however, is only confined to offenses under the IPC but not to other Acts, e.g., the Railway Act.83A child above seven and under twelve years of age is presumed to be capable of committing an offence it he has obtained sufficient maturity to understand and judge the nature and consequences of his conduct on that occasion. The law presumes such maturity' in a child of that age unless the contrary is proved by the defence.89A child under 12 years of age cannot give valid consent to suffer any harm which can occur from an act done in good faith and for its benefit, e.g., a consent for an operation. Only, a guardian can give such consent.87A person under 12 years of age cannot give valid consent, whether express or implied, to suffer any harm which may result from an act no intended or not known to cause death or grievous hurt e.g. consent for a wrestling contest.84Nothing is an offence which is done by a person who at the time of doing it, by reason of unsoundness of mind, is uncapable of knowing the nature of act (i.e. it is wrong or contrary to law).85,86Drunkness and criminal responsibilityQ | Forensic Medicine | {

Bacteriology | 4f18ef6e-5055-4a92-b508-642d9489bee3 | Mycobacterium are slender rods that sometimes show branching, filamentous forms resembling fungal mycelium. In liquid cultures, they form a mould like a pellicle. they do not stain readily, but once stained, resist decolourisation with dilute mineral acids, due to the presence of mycolic acid in their cell wall. They are called acid-fast bacilli. Mycobacterium are slow-growing, aerobic, non-motile, non-capsulated and non-sporing.

As such, it can allow for the rapid identification and quantification of populations of WBC in any given patient sample based on the characteristic immunophenotype of the population subset.Also know:Flow cytometry can be a vital investigational tool for the hospitalist. It can be used in the initial workup of a new leukocytosis to identify a malignant versus a benign reactive cause. Flow cytometry also has direct uses in nonmalignant hematologic conditions, such as in the determination of CD4/CD8 count ratios in HIV-associated lymphocytopenia or in the diagnosis of rarer conditions such as paroxysmal nocturnal hemoglobinuria and Langerhans cell histiocytosis.

Colposcopic findings may be used for assigning a stage to the tumour for instance FIGO stage HA. - Chest radiograph and electrocardiographic studies are used to determine cardiopulmonary disease paicularly in oder patients. Pulmonary function studies can be impoant especially for evaluating patients who are candidates for extensive surgery. Remember CT scan, MRI lymphangiography and PET scan may offer information helpful for treatment planning but these findings do not change the FIGO stage of the disease. Pelvic examinations and clinical staging as defined by FIGO cannot detect metastasis such as paraaoic lymph node metastasis. Consequently there is growing body of literature showing the superiority of cross-sectional imaging computed Tomography (CT) and magnetic resonance imaging (MRI) over clinical staging in delineating the extent of the disease in patient with cervical cancer. The official FIGO guidelines do not incorporate the use of either CT or MRI findings into the staging of cervical cancer. This is due to the FIGO guideline that staging methods should be universally available so that staging can be standardized means of communication between different institutions wordwide. | Surgery | {

Metabolism of lipid | da1622c6-0278-437f-872c-c897f740b90d | KETOSIS Under ceain metabolic conditions associated with a high rate of fatty acid oxidation, liver produces considerable quantities of compounds like acetoacetate and bbb-OH butyric acid, which pass by diffusion into the blood. Acetoacetate continually undergoes spontaneous decarboxylation to produce acetone. These three substances are collectively known as "ketone bodies" (or "acetone bodies"). Sometimes also called as "ketones", which is rather a misnomer. KETONE BODY FORMATION IN LIVER (KETOGENESIS) Enzymes are mitochondrial: Steps 1. Aceto-acetyl-CoA: Aceto-acetyl-CoA is the staing material for ketogenesis. This can arise in two ways: (a)Directly during the course of b-oxidation of fatty acids, or (b)As a result of condensation of two C-2 units, i.e. 'active acetate' (acetyl-CoA) by reversal of thiolase reaction. 2. Formation of Acetoacetate: Acetoacetate is the first ketone body to be formed. This can occur in two ways: a) By deacylation: Acetoacetate can be formed from aceto-acetyl-CoA by simple deacylation catalysed by the enzyme aceto-acetyl-CoA deacylase. SECTION FOUR when excessive amount of ketone bodies are formed, the The above does not seem to be the major pathway deacylation reaction is not enough to cope up. (b) Second pathway: Formation of acetoacetate intermediate production of "bbb-OH-bbb-methyl glutaryl CoA" (HMG-CoA). Present opinion ours the HMG-CoA pathway as the major route of ketone body formation. Steps Involves two steps: * Condensation of aceto-acetyl-CoA with another molecule of acetyl-CoA to form b-OH-b methyl glutaryl-CoA (HMG-CoA) catalysed by the enzyme HMG-CoA synthase (mitochondrial enzyme). *HMG-CoA is then acted upon by an another enzyme, HMG-CoA Lyase, which is also mitochondrial enzyme, to produce one molecule "acetoacetate" and one molecule of acetyl-CoA (Fig. 25.10). Note *Both the enzymes HMG-CoA synthase and HMG-CoA Lyase are mitochondrial and must be available in mitocondrion for ketogenesis to occur. *Both the enzymes are present in liver cells mitochon- dria only. *A marked increase in activity of HMG-CoA Lyase has been noted in fasting. *HMG-CoA is a committed step. Cholesterol also can be formed by "HMG-CoA reductase". 3. Formation of Acetone: As stated earlier, acetone is formed from acetoacetate by spontaneous decarboxy- lation (Non-enzymatic). 4.Formation of b-OH Butyrate: Acetoacetate once formed is conveed to b-OH-butyric acid; the reaction is catalysed by the enzyme b-OH-butyrate dehydro- genase, which is present in liver and also found in many other tissues. b-OH-butyrate is quantitatively the predominant ketone body present in blood and urine in KetosisRef: Textbook of Medical Biochemistry Dr (Brig) MN Chatterjea Rana Shinde, page no: 425,426 | Biochemistry | {

Abdomen & Pelvis | 3cf75233-8038-4c9d-be24-cb4f28f100c8 | The afferent fibers mediating the pain from the head of the pancreas run initially with the greater thoracic splanchnic nerves. The greater splanchnic nerves arise from sympathetic ganglia at the levels of T5 to T9 and innervate structures of the foregut and thus the head of the pancreas. Running within these nerves are visceral afferent fibers that relay pain from foregut structures to the dorsal horn of the spinal cord. Also entering the dorsal horn are the somatic afferents from that vertebral level, which mediate pain from the body wall. Intercostal nerves T1 to T12 provide the terminal part of the pathway to the spinal cord of visceral afferents for pain from the thorax and much of the abdomen. Therefore, pain fibers from the pancreas pass by way of the splanchnic nerves to the sympathetic chains and then, by way of communicating rami, to ventral rami of intercostal nerves, finally entering the spinal cord by way of the dorsal roots. The phrenic nerve innervates the diaphragm and also carries visceral afferents from mediastinal pleura and the pericardium, but it does not carry with it any visceral afferent fibers from the pancreas. The vagus nerve innervates the pancreas with parasympathetic fibers and ascends all the way up to the medulla where it enters the brain. It has no visceral afferent fibers for pain.

Ear | b4de3125-ce37-4e6e-84fa-faf1f81e56d8 | Gelle's test: It is also a test of bone conduction and examines the effect of increased air pressure in ear canal on the hearing. Normally, when air pressure is increased in the ear canal by Siegel's speculum, it pushes the tympanic membrane and ossicles inwards, raises the intralabyrinthine pressure and causes immobility of basilar membrane and decreased hearing, but no change in hearing is observed when ossicular chain is fixed or disconnected. Gelle's test is performed by placing a vibrating fork on the mastoid while changes in air pressure in the ear canal are brought about by Siegel's speculum. Gelle's test is positive in nor- mal persons and in those with sensorineural hearing loss. It is negative when ossicular chain is fixed or disconnected.

Atherosclerosis (Senile gangrene) Seen in elderly people over 50 years of age. Thus because of age factor we can rule out atherosclerosis. Myocardial infaction Age factor again helps in ruling it out as MI is generally seen in elderly, though its incidence is increasing in young, but it cannot be a more common cause than Buerger's disease. Buerger's (Thromboangitis obliterans) Usual victims of this ds are young men below 40 yrs of age, who are smokers (ds is not seen in females and nonsmokers). Buerger ds is the inflammatory reaction in the aerial wall with involvement of the neighbouring vein and nerve, terminating in thrombosis of the aery. It characterstically involves small and medium sized aeries (plantars, tibial and radial aery) Both upper and lower extremities are affected. In lower extremity the ds. occurs beyond the popliteal aery. In upper extremity the ds occurs beyond the brachial a. Early in the course of Buergers ds the superficial veins are involved producing the characterstic migratory, recurrent superficial thrombophlebitis. An imp difference with atheroselerosis is that, atherosclerosis is a disease of large sized aeries, buergers is a ds of small aeries. | Surgery | {

Gluteus MaximusThe superior gluteal nerve arises from the sacral plexus in the pelvis and is formed by the dorsal branches of the ventral rami of L4, L5; S1. It enters the gluteal region through the greater sciatic notch above the piriformis in company with superior gluteal artery. Here it curves upward and forward, runs between the gluteus medius and the minimus, and supplies both of them. It then comes out by passing between the anterior borders of these muscles and supplies the tensor fasciae latae from its deep surface. It also provides an articular twig to the hip joint. | Anatomy | {

Chemotherapy | 9fd049a3-b32a-4f2d-badb-206e46dd84c6 | Amphotericin B (AMB): It is obtained from Streptomyces nodosus. Chemistry and mechanism of action The polyenes possess a macrocyclic ring, one side of which has several conjugated double bonds and is highly lipophilic, while the other side is hydrophilic with many OH groups. A polaraminosugar and a carboxylic acid group are present at one end in some. They are all insoluble in water and unstable in aqueous medium. The polyenes have high affinity for ergosterol present in fungal cell membrane: combine with it, get inseed into the membrane and several polyene molecules together orient themselves in such a way as to form a &;micropore&;. The hydrophilic side forms the interior of the pore through which ions, amino acids and other watersoluble substances move out. The micropore is stabilized by membrane sterols which fill up the spaces between the AMB molecules on the lipophilic side-constituting the outer surface of the pore. Thus, cell permeability is markedly increased. New amphotericin B formulations In an attempt to improve tolerability of i.v. infusion of AMB, reduce its toxicity and achieve targeted delivery, 3 new lipid formulations of AMB have been produced. (a) Amphotericin B lipid complex (ABLC): Contains 35% AMB incorporated in ribbon like paicles of dimyristoyl phospholipids. ( b ) Amphotericin B colloidal dispersion (ABCO). Disc shaped paicles containing 50% each of AMB and cholesteryl sulfate are prepared as aqueous dispersion (c) Lpi osomal amphotericin B (small unilamellar vesicles SUV): Consists of 10% AMB incorporated in uniform sized (60-80 nM) unilamellar liposomes made up of lecithin and other biodegradable phospholipids. The special features of these preparations are: * They, except ABCD, produce milder acute reaction (especially liposomal formulation) on i.v. infusion. * They can be used in patients not tolerating infusion oi conventional AMB formulation. * They have lower nephrotoxicity. * They cause minimal anaemia. * The liposomal preparation delivers AMB paicularh* to reticuloendothelial cells in liver and spleen-----especialh valuable for kala azar and in immunocompromised patients. However, some preparations, especially ABLC and ABCD, produce lower AMB levels and their clinical efficacy relative to conventional formulations appear to be lower. Though none of the above formulations is more effectivein deep mycosis than conventional AMB, the liposomal AMB reduces equivalent blood levels, has similar clinical efficacy with less acute reaction and renal toxicity. It thus apears more satisfactory. ESSENTIALS OF MEDICAL PHARMACOLOGY K.D.TRIPATHI SIXTH EDITION PAGE NO:757,758,759 | Pharmacology | {

For this purpose the organ should be perfused with organ preservative solution twice before it is transplanted to the recipient. The first perfusion is done just after the abdomen is opened at laporotomy and the second perfusion is done just after the organ has been removed from the donor. Commonly used preservative solutions include UW solution (University of Wisconsin) and Eurocollins solution. After removal from the donor, the organ is placed in two sterile bags and stored at 0-4degC by immersion in ice while they are transpoed to the recipient centre Ref srb's manual of surgery 5e p993 , Internet | Anatomy | {
