Subdural hematomas are often life-threatening when acute but chronic subdural hematomas, however, have better prognosis if properly managed. Chronic subdural hematomas are common in the elderly due to shrinkage of brain tissue, but in young patient mostly associated with head injury. It is seen also in young having various coagulopathies associated with blood disorders or drug-induced, but it is very rare. Propylthiouracil (PTU) is an oral medication that is used in treatment of hyperthyroidism approved by FDA in July 1947. This medication may rarely cause very serious blood disorders (such as a low number of red cells, white cells, and platelets), especially during the first few months of treatment. We are reporting a rare case of PTU-induced thrombocytopenia leading to chronic subdural haematoma, which presented with established papilledema and signs of raised ICP in a hyperthyroid female and she responded well to surgical management.

A 55-year-old female known case of essential hypertension and diabetes was brought to the Emergency Department in a drowsy state with cardiogenic shock. At presentation systolic BP was 70 mm Hg, pulse rate was 44/min and random blood sugar was 239 mg/dl. Troponin I was 8.07. Electrocardiography showed junctional rhythm and bradycardia. Ejection Fraction (LVEF) was 15% - 20%. Coronary angiography was done which revealed single vessel disease in LAD with anomalous origin of RCA from midsegment of LAD. Patient was immediately taken up for Off-pump Coronary Artery Bypass Grafting (OPCAB). Right saphenous vein graft was harvested and anastomosed proximally to aorta and distally to LAD on beating heart using Medtronic Octopus heart stabilizer and coronary shunts. Wound closed in layers after achieving complete hemostasis. Patient was taken off ventilatory support on first post-operative day and discharged in a stable condition on fourth post-operative day. Post-operative Echocardiography showed LVEF increased from 15% - 20% at time of admission to 38% and 52% after 3 months and 12 months of surgery respectively.

Devices participating in mobile ad hoc networks (MANET) are expected to strictly adhere to a uniform routing protocol to route data packets among themselves. Unfortunately, MANET devices, composed of untrustworthy software and hardware components, expose a large attack surface. This can be exploited by attackers to gain control over one or more devices, and wreak havoc on the MANET subnet. The approach presented in this paper to secure MANETs restricts the attack surface to a?single module?in MANET devices a trusted MANET module (TMM). TMMs are deliberately constrained to demand only modest memory and computational resources in the interest of further reducing the attack surface. The specific contribution of this paper is a precise characterization of simple TMM functionality suitable for any distance vector based routing protocol, to realize the broad assurance that “any node that fails to abide by the routing protocol will not be able to participate in the MANET”.
