BACKGROUND In September 2012, the World Health Organization reported the first cases of pneumonia caused by the novel Middle East respiratory syndrome coronavirus (MERS-CoV). We describe a cluster of health care–acquired MERS-CoV infections. METHODS Medical records were reviewed for clinical and demographic information and determination of potential contacts and exposures. Case patients and contacts were interviewed. The incubation period and serial interval (the time between the successive onset of symptoms in a chain of transmission) were estimated. Viral RNA was sequenced. RESULTS Between April 1 and May 23, 2013, a total of 23 cases of MERS-CoV infection were reported in the eastern province of Saudi Arabia. Symptoms included fever in 20 patients (87%), cough in 20 (87%), shortness of breath in 11 (48%), and gastrointestinal symptoms in 8 (35%); 20 patients (87%) presented with abnormal chest radiographs. As of June 12, a total of 15 patients (65%) had died, 6 (26%) had recovered, and 2 (9%) remained hospitalized. The median incubation period was 5.2 days (95% confidence interval [CI], 1.9 to 14.7), and the serial interval was 7.6 days (95% CI, 2.5 to 23.1). A total of 21 of the 23 cases were acquired by person-to-person transmission in hemodialysis units, intensive care units, or in-patient units in three different health care facilities. Sequencing data from four isolates revealed a single monophyletic clade. Among 217 household contacts and more than 200 health care worker contacts whom we identified, MERS-CoV infection developed in 5 family members (3 with laboratory-confirmed cases) and in 2 health care workers (both with laboratory-confirmed cases). CONCLUSIONS Person-to-person transmission of MERS-CoV can occur in health care settings and may be associated with considerable morbidity. Surveillance and infection-control measures are critical to a global public health response.

The findings in our study supported the theory of primary weakness of the vein wall as a cause of varicosity. This weakness is due to intimal changes, disturbance in the connective tissue components and smooth muscle cells.

Laparoscopy is safe and readily establishes the diagnosis of peritoneal TB.

Two sibs with an infantile onset of hyperglycemia, recurrent hepatitis, renal insufficiency, developmental delay, and skeletal epiphyseal dysplasia are described. Clinical presentation and radiological features are suggestive of Wolcott-Rallison syndrome, a rare autosomal recessive disease. In both of our cases we found evidence of central hypothyroidism, which appears to be an associated feature of this syndrome. Hypothyroidism should be suspected and screened for in all cases of Wolcott-Rallison syndrome.

Background/Aim:Previous studies regarding the outcome of laparoscopic cholecystectomy (LC) in men have reported inconsistent findings. We conducted this prospective study to test the hypothesis that the outcome of LC is worse in men than women.Materials and Methods:Between 1997 and 2002, a total of 391 consecutive LCs were performed by a single surgeon at King Fahd Hospital of the University. We collected and analyzed data including age, gender, body mass index (kg/m2), the American Society of Anesthesiologists (ASA) class, mode of admission (elective or emergency), indication for LC (chronic or acute cholecystitis [AC]), comorbid disease, previous abdominal surgery, conversion to open cholecystectomy, complications, operation time, and length of postoperative hospital stay.Results:Bivariate analysis showed that both genders were matched for age, ASA class and mode of admission. The incidences of AC (P = 0.003) and comorbid disease (P = 0.031) were significantly higher in men. Women were significantly more obese than men (P < 0.001) and had a higher incidence of previous abdominal surgery (P = 0.017). There were no statistical differences between genders with regard to rates of conversion (P = 0.372) and complications (P = 0.647) and operation time (P = 0.063). The postoperative stay was significantly longer in men than women (P = 0.001). Logistic regression analysis showed that male gender was not an independent predictor of conversion (Odds ratio [OR] = 0.37 and P = 0.43) or complications (OR = 0.42, P = 0.42). Linear regression analysis showed that male gender was not an independent predictor of the operation time, but was associated with a longer postoperative stay (P = 0.02).Conclusion:Male gender is not an independent risk factor for satisfactory outcome of LC in the experience of a single surgeon.

Among 527 patients with thyroid disease who underwent surgery at our hospital during a 20-year period, 2 (0.4%) had tuberculous thyroiditis mimicking carcinoma. The first patient was a 44-year-old man with a solitary thyroid nodule and the second was a 24-year old man with a thyroid abscess. The unexpected diagnosis was made postoperatively and was based on histological findings in both patients. No primary focus was found elsewhere in either patient, and both responded to antituberculous chemotherapy. Although the diagnosis is usually based on examination of resected specimens, recent reports indicate that find-needle aspiration cytology is a cost-effective technique of diagnosing thyroid tuberculosis. A review of 35 cases reported in the English literature is also discussed.

Laparoscopy is a feasible and safe alternative to laparotomy for most patients with acute small bowel obstruction.

HighlightsGallstone ileus is a rare cause of small bowel obstruction usually in elderly females.Surgery is the mainstay treatment without a clear consensus about the best approach.This female underwent an uneventful total laparoscopic management of gallstone ileus.Laparoscopic enterolithotomy is safe, feasible and effective when performed by experienced surgeons.
