Experience of King Abdullah Medical City in Placement of Inferior Vena Cava Filter Prior to Bariatric Surgery in Extremely High-Risk Patients for Thromboembolic Events.

INTRODUCTION: Bariatric surgery is used to treat morbid obese patients. Venous thromboembolism (VTE) is considered to be one of the leading causes of postoperative morbidity and mortality. Therefore, inferior vena cava filter (IVCF) is used to minimize the risk of VTE in high-risk patients. MATERIALS AND METHODS: Medical information was collected for the preoperative, operative and postoperative stages for all patients underwent bariatric surgery at KAMC from March 2013 to July 2017. RESULTS: Five cases with IVCF were included in this study. Age ranged from 35 to 66 years old; 4 (80%) were female. Preoperative body mass index ranged from 42 to 64 kg/m2. Postoperative findings were reported. CONCLUSION: IVCF seems to be beneficial for patients undergoing bariatric surgery.

Dengue fever. Clinical features of 567 consecutive patients admitted to a tertiary care center in Saudi Arabia.

OBJECTIVES: To delineate the clinical features and outcomes of dengue infection and to guide clinician of early diagnosis and identification of risks factors for dengue hemorrhagic fever. Methods: This study is a retrospective cross-sectional. Clinical records of 567 patients with a confirmed diagnosis of dengue infection, admitted to a single hospital in Jeddah, Saudi Arabia, between January 2010 and  June 2014 were reviewed.  Results: Dengue infection was most common in adult males. Sixty-eight percent of infections were in Saudi nationals. In addition to the diagnostic clinical features, leucopenia and thrombocytopenia were typical of dengue infection. Approximately 4.1% of adult patients and 7.1% of pediatric patients developed dengue hemorrhagic fever (DHF). Abdominal pain and vomiting were more common in patients developing DHF. Mean platelet count was lower in adult, but not pediatric patients developing DHF. Peak alanine aminotransferase (ALT) was higher in adult and pediatric patients developing DHF. Three patients died, 2 of them developed DHF. Ninety-eight percent of adult patients and 92% of pediatric patients made a full recovery. Conclusions:   Dengue infection is common in Jeddah.  Abdominal pain and vomiting, thrombocytopenia, and elevated ALT are typical of severe infection, which is more likely to be associated with significant morbidity and mortality.
