Sinus node dysfunction complicating viper bite.

Viper venom toxicities comprise mainly bleeding disorders and nephrotoxicity. Cardiotoxicity is a rare manifestation of viper bite. We describe the case of a previously healthy 35-year-old man who developed coagulopathy and sinus node dysfunction following a viper bite.

Coronary artery disease in patients undergoing cardiac surgery for non-coronary lesions in a tertiary care centre.

Background: The objective of the present study was to determine the prevalence of coronary artery disease (CAD) in patients undergoing surgery for various valvular as well as non-valvular cardiac pathologies.

Methods: Patients with various valvular and non-valvular pathologies were selected. All patients with age ≥ 40 years and an indication for open heart surgery underwent pre-operative coronary angiogram and were included in the study.

Persistent left superior vena cava draining into left atrium as a cause of persistent systemic desaturation after surgery.

Persistent left superior vena cava (LSVC) is a rare congenital anomaly which usually produces no physiologic derangements if it drains into the right atrium via the coronary sinus, but it may cause significant desaturation when it drains into the left atrium (LA). Failure to diagnose LSVC communicating with the LA preoperatively may lead to serious consequences. We are describing an interesting case of a boy who presented with systemic desaturation due to an undetected LSVC after having undergone corrective surgery for atrioventricular canal defect.

Successful percutaneous removal of broken mitral valvuloplasty coiled tip guidewire.

Complications related to hardware malfunction during balloon mitral valvuloplasty (BMV) are rarely met in catheterization laboratory. However, the consequences can be grave including death. We report an extremely rare complication of fracture of BMV coiled tip guidewire, which was successfully retrieved percutaneously with a relatively simple technique.

Endocrine complications in long-term survivors after allogeneic stem cell transplant.

As survival rates continue to increase after allogeneic stem cell transplant (allo-SCT), the associated long-term complications of transplant need to be taken into consideration. Here, we review the endocrine and metabolic complications associated with transplant survivors, including diabetes, dyslipidemia, hypertension, cardiovascular disease, hypogonadism, vitamin D deficiency, osteoporosis, thyroid disease, adrenal dysfunction, and pituitary disorders, and provide a brief summary of evaluation and treatment of these conditions.

Clinical markers implying the need for treatment in women with gestational diabetes mellitus.

Objective: To assess the association of the point-of-care hemoglobin A1c (POC A1C), fasting blood glucose (FBG), and BMI with fetal macrosomia and the need for medication in women with gestational diabetes (GDM).

Methods: POC A1C, FBG, and BMI values at GDM diagnosis and fetal weight at delivery were obtained for women identified from a prospective patient registry. These outcomes were compared between women who did not require medication for GDM and women who did require medication.

Oral cavity metastasis of renal cell carcinoma: a case report.

Introduction: Despite being reported rarely, renal cell carcinoma is the third most frequent neoplasm to metastasize to the head and neck region preceded only by breast and lung cancer. Little information exists regarding the presentation and work-up of metastatic renal cell carcinoma in the oral cavity.

Case Presentation: We report the case of a 63-year-old Caucasian man presenting with an oral cavity lesion that was painful and that had grown substantially over several months.

Adenoid cystic carcinoma of the parotid gland with temporal bone invasion.

Objective: To present our series of 16 patients with adenoid cystic carcinoma (ACC) of the parotid gland with temporal bone invasion.

Patients: All patients treated at our institution between July 1988 and July 2004 with parotid gland ACC with temporal bone invasion.

Interventions: Preoperative radiographic assessment with combined surgical and radiation therapy treatment.
