Paranoia is a self-inflicted mental torture of which the sufferer himself is unaware. A paranoiac is perpetually guarded and suspicious, convinced that he is being persecuted by all who inhabit his deluded world.

Here we analyze results from three recent papers (2009, 2011, 2012) by Dr. Jens Förster from the Psychology Department of the University of Amsterdam. These papers report 40 experiments involving a total of 2284 participants (2242 of which were undergraduates). We apply an F test based on descriptive statistics to test for linearity of means across three levels of the experimental design. Resul...

Hernia of Morgagni is congenital defects in the diaphragm. They are mostly asymptomatic and present with vague symptoms when they do so. A high index of suspicion is required for timely diagnose of this condition. Here we present the case of a 65-year-old male patient presented to our institute with constipation for the past six months. Chest radiology raised the suspicion of a hernia which was...

The radiological finding of a calcified intracranial lesion commonly represents a slow growing benign mass. Brain metastases originating from colorectal cancers are rare, occurring in approximately 2-3% of patients. Therefore the presence of a calcified brain lesion in a patient with a positive oncological history requires a high index of suspicion for brain metastases. Presented herein is a ca...

The literature on adrenal gland tumour in HIV-infected patients is scarce. We report a 46-year-old Malay man with HIV and Hepatitis C infection presenting with a large nonfunctioning adrenal tumour. Computed tomography showed a large right adrenal tumour with heterogeneous enhancement and central necrosis. A high index of suspicion of a malignant tumour or pheochromocytoma led us to surgical re...

A retrospective study was made of 100 consecutive dedicated per-oral small bowel examinations. 33% of the studies were abnormal, of which almost half were due to Crohn's disease. When grouped according to clinical suspicion, 73.5% of those studies with a high index of clinical suspicion were abnormal. In the abnormal group a correct diagnosis was made in 90%, with two false positives. In the no...
