Early Detection of Osteoporosis by Dual Energy X-ray Absorptiometry.

Background And Objective: An early detection of osteoporosis through DEXA procedure will not only improve the disease management practices but also would help in impeding national productivity losses by mass screening and awareness. Our objective was to measure efficacy of DEXA procedure in early detection of osteoporosis and prevention of its complications.

Methods: This case series observational study was designed to confirm the bone mineral density by dual energy x-ray absorptiometery (DEXA).

Plasma homocysteine in patients of migraine without aura.

Background: Few studies have studied the role of homocysteine in migraineurs and have produced conflicting results. The MTHFR C677T genotype has been associated with increased risk of migraine in selected clinical samples. We assessed the association of the MTHFR C677T variant with migraine, the corresponding homocysteine levels and their correlation.

Metabolic investigations in patients with hepatitis B and C.

Aim: To investigate the similarities and dissimilarities in patients with hepatitis B and hepatitis C, clinically and metabolically.

Methods: Fifty patients with hepatitis B virus and hepatitis C virus infection were included in this study, along with fifty healthy controls for comparison purposes. Intravenous blood (10 mL) samples from patients and healthy subjects were collected and made to clot before serum was separated and immediately levels of the enzymes, alkaline phosphatase (ALK), creatinine phosphokinase (CPK), lactate dehydrogenase (LDH), serum glutamate oxaloacetate transaminase (s-GOT) and serum glutamate pyruvate transaminase (s-GPT) were determined by a kit method.

Clinical characteristics of 226 college-going female migraineurs in Lahore, Pakistan - putting ICHD-2 to the road test.

The International Headache Society (IHS) criteria-based questionnaires were given to 647 college-going females (faculty and students) of selected universities in Lahore, Pakistan. Forty five (7%) were diagnosed with Migraine with Aura (MWA), 181 (28%) with Migraine without Aura (MWOA) and 421 (65%) as NMH (non-migrainous headache). We found 'Photophobia and Phonophobia' as the most common headache-associated symptoms, and 'Stress' and lack of sleep' as the most commonly reported triggers of MWA (44%) and MWOA (38%).

Surgical site infection rate and associated risk factors in elective general surgery at a public sector medical university in Pakistan.

This prospective study aimed to determine the surgical site infection (SSI) rate and associated risk factors was carried in a general surgical ward at Liaquat University Hospital Jamshoro. A total of 460 patients requiring elective general surgery from July 2005 to June 2006 were included in this study. All four surgical wound categories were included.
