Postmenopausal virilization secondary to a large ovarian cystadenoma with stromal hyperthecosis.

Ovarian cystadenomas may present in a functional manner. Biochemical workup of seemingly benign ovarian lesions should be considered in the appropriate clinical context.

Do delays in surgery affect outcomes in patients with inter-trochanteric fractures?

Objective: To study the differences in outcomes of early versus delayed surgery in patients with intertrochanteric fractures.

Methods: The retrospective chart review was conducted at Aga Khan University Hospital, Karachi, and comprised data of patients who underwent surgery for intertrochanteric hip fractures from 2005 to 2010. A gap of >48hours between the event and the surgery was considered a delayed procedure and its impact on outcome was assessed.

Laparoscopic-assisted percutaneous endoscopic gastrostomy tube insertion in the immediate post-partum period for head and neck cancer.

Percutaneous endoscopic gastrostomy (PEG) tube placement serves as a well-tolerated and efficacious technique for long-term enteral access in patients with medical conditions precluding oral food intake. The nutritional optimisation of patients with oral cancer is mostly achieved via PEG tube placement. However, certain special situations, such as pregnancy and the immediate post-partum period, may render the placement of PEG tubes to be a challenge.

Near complete aortic transection and its successful repair using a novel cardiopulmonary bypass technique.

The case of a 38-year old female, victim of a road traffic accident who presented with a near complete aortic transection is presented. An emergent repair employing cardiopulmonary bypass was attempted in the operating room. Anticipating a high-risk of compromise to cerebral perfusion from air micro-emboli, the bypass was attempted with an innovative approach involving the successful cannulation of the pulmonary artery and descending aorta.

Dynamic hip screw fixation for inter-trochanteric fractures: determinants of outcomes.

Objective: To evaluate factors associated with revision of dynamic hip screw implant in patients undergoing the procedure for the fixation of intertrochanteric fractures.

Methods: The retrospective study was conducted at the Aga Khan University Hospital, Karachi, and comprised records of patients who had undergone dynamic hip screw fixation surgery between 2008 and 2012. Medical records and data for all patients were obtained from the medical records office.

Abdominal gunshot wounds-a comparative assessment of severity measures.

Background: Penetrating abdominal trauma is a common feature of trauma treated in low- and middle-income countries (LMICs). The penetrating abdominal trauma index (PATI) and the injury severity score (ISS) are severity-measures most often used to gauge injury severity. It remains unclear which measure better accounts for the severity of sustained injuries.

Angiographic embolization for major trauma in a low-middle income healthcare setting--A retrospective review.

Introduction: Interventional radiology (IR) provides a range of adjunctive techniques to assist with hemorrhage control after trauma that can be employed pre- or post-operatively. The role of IR in lower-middle income countries (LMICs) remains unexplored. This study describes the use of adjunctive angioembolization (AE) in severely injured patients following its recent implementation at an urban trauma center in a LMIC.

National estimates of predictors of outcomes for emergency general surgery.

Background: Identifying predictors of mortality and surgical complications has led to outcome improvements for a variety of surgical conditions. However, similar work has yet to be done for factors affecting outcomes of emergency general surgery (EGS). The objective of this study was to determine the predictors of in-hospital complications and mortality among EGS patients.

Impact of a predefined hospital mass casualty response plan in a limited resource setting with no pre-hospital care system.

Introduction: Pre-hospital triage is an intricate part of any mass casualty response system. However, in settings where no such system exists, it is not known if hospital-based disaster response efforts are beneficial. This study describes in-hospital disaster response management and patient outcomes following a mass casualty event (MCE) involving 200 victims in a lower-middle income country in South Asia.

Obesity and the need for bariatric surgery in Pakistan.

After establishing a foothold in the West, the pandemic of obesity now threatens to spin out of control in the developing nations of Asia and the Indian subcontinent. Like many of its neighbors, Pakistan has witnessed an unprecedented growth in the number of overweight and obese individuals in its population, and obesity is proving to be an issue of considerable public health concern. Conventional medical therapies for obesity and related complications have proven to be less than effective, especially in the population of the southeast, which appears to be inherently predisposed to developing obesity-related complications.

Hip fracture surgery: does type of anesthesia matter?

Background: Hip fracture surgery is a common procedure, and the geriatric population with its multiple comorbid conditions is at most at risk of developing anesthesia-related complications. Data on the impact of type anesthesia on postoperative morbidity and mortality is limited. The effects of regional and general anesthesia on postoperative outcomes need to be clearly elucidated.

A randomized, double-blind, placebo-controlled trial of oral montelukast in acute asthma exacerbation.

Background: Leukotriene receptor antagonists (LTRAs) are well established in the management of outpatient asthma. However, there is very little information as to their role in acute asthma exacerbations. We hypothesized that LTRAs may accelerate lung function recovery when given in an acute exacerbation.

Resident work hour reforms: implications regarding hip fracture surgery.

Background: Resident work hour reforms were developed by Aga Khan University Postgraduate Medical education committee in the year 2005. These reforms were implemented by the section of Orthopedics in winter 2006. We designed this study to determine if there is a difference in morbidity and mortality following Dynamic Hip Screw (DHS) fixation for intertrochanteric fracture patients before and after implementation of work hour reforms.

Pulmonary talcosis 10 years after brief teenage exposure to cosmetic talcum powder.

Pulmonary talcosis is a rare but debilitating variant of pneumoconiosis often presenting with isolated non-specific symptoms of progressive exertional dyspnoea or cough. Occupational exposure to talc dust and intravenous drug abuse are well-recognised aetiological factors with only a few cases related to cosmetic talc exposure being reported to date. The authors report a case of a young woman in whom a mere 4 month ritual of inhaling cosmetic talcum powder led to full-blown pulmonary talcosis being diagnosed 10 years later.
