Background: Stroke is a major cause of death in the western world, and carotid endarterectomy has been shown to be effective in treating both symptomatic and asymptomatic carotid stenosis. Carotid stenting is a relatively new form of treatment for carotid stenosis and few studies have looked specifically at asymptomatic patients.
Objectives: To retrospectively examine short- and long-term results in the treatment of asymptomatic carotid artery stenosis with surgery or stenting.
Methods: We retrospectively collected data of all patients with asymptomatic carotid stenosis treated by carotid artery stenting or carotid endarterectomy in our department from 2006–2007. The primary endpoints were stroke, myocardial infarction, or death during the periprocedural period; or any ipsilateral stroke, restenosis, or death within 4 years after the procedure.
Results: The study comprised 409 patients who were treated by either stenting or surgery. There was a low morbidity rate in both treatment groups with no significant difference in morbidity or mortality between the treatment groups in both in the short-term as well as long-term.
Conclusion: Both treatment methods have a low morbidity and mortality rate and should be considered for patients with few risk factors and a long life expectancy. Treatment method should be selected according to the patient's individual risk factors and imaging data.

Background: Concerns about metformin-associated lactic acidosis (MALA) prohibit the use of metformin in a large subset of diabetic patients, mostly in patients with chronic kidney disease. Increasing evidence suggests that the current safety regulations may be overly restrictive.
Objectives: To examine the association between chronic metformin treatment and lactate level in acute illness on the first day of admission to an internal medicine ward.
Methods: We compared diabetic and non-diabetic hospitalized patients treated or not treated with metformin in different sets of kidney function.
Results: A total of 140 patients participated in the study, 54 diabetic patients on chronic metformin treatment, 33 diabetic patients without metformin and 53 patients with no diabetes. Most participants were admitted for conditions that prohibit metformin use, such as heart failure, hypoxia and sepsis. Average lactate level was significantly higher in the diabetes + metformin group compared to the diabetes non-metformin group. Metformin treatment was not associated with higher than normal lactate level (hyperlactatemia) or low pH. No patient was hospitalized for lactic acidosis as the main diagnosis.
Conclusions: Chronic metformin treatment mildly increases lactate level, but does not induce hyperlactatemia or lactic acidosis in acute illness on the first day of admission to an internal medicine ward. These data support the expansion of metformin use.

Background: Both high and insufficient weight gain during pregnancy have been associated with adverse outcomes for mothers and their offspring.
Objectives: To describe self-reported weight gain during pregnancy, assess the concurrence of this weight gain with issued recommendations, and investigate associations between lifestyle factors and weight gain.
Methods: In this cross-sectional study, 109 pregnant women hospitalized in one gynecological and obstetrics department completed questionnaires related to weight gain and lifestyle factors such as smoking, diet and exercise. Recommended weight gain was defined by the American Congress of Obstetricians and Gynecologists and was compatible with the Ministry of Health guidelines in Israel.
Results: Fifty-three (49%) participants reported weight gain above the recommendation, 31 (28%) met the recommendations and 25 (23%) reported weight gain below the recommendations. Characteristics associated with high weight gain included past smoking and/or age above 36 years and/or body mass index (BMI) above 25 kg/m2. Only 34 women (31%) reported seeking professional nutritional counseling during pregnancy. An increased tendency to consult a nutritionist was reported among diabetic women.
Conclusion: Only a minority of women gained the recommended weight during pregnancy. High BMI and/or a history of smoking and/or older age were associated with weight gain above recommendations. Particular effort should be directed toward counseling women at high risk of weight gain during pregnancy.

Background: It is a challenge to diagnosis Clostridium difficile colitis.
Objectives: To determine, among patients who developed nosocomial diarrhea, whether serum procalcitonin (PCT) can distinguish between C. difficile toxin (CDT)-positive and CDT-negative patients.
Methods: This prospective study included 50 adults (>18 years) who developed diarrhea during hospitalization, 25 with a positive fecal test for CDT (study group) and 25 CDT negative (control group).
Results: Baseline demographic and underlying illnesses were similar in both groups. Duration of diarrhea was 6 ± 4 days and 3 ± 1 in the study and control groups, respectively (P = 0.001). Mean blood count was 20 ± 15 and 9.9 ± 4, respectively (P = 0.04). CRP level was higher in the study than in the control group (10.9 ± 7.4 and 6.6 ± 4.8, P = 0.028). PCT level was higher in the study group (4.4 ± 4.9) than the control group (0.3 ± 0.5, P = 0.102). A PCT level > 2 ng/ml was found in 7/25 patients (28%) and 1/25 (4%), respectively [odds ratio 9.33, 95% confidence interval (0.98 to 220), P = 0.049]. Multivariate analysis showed that only duration of diarrhea and left shift of peripheral leucocytes were significant indicators of CDT (P = 0.014 and P = 0.019, respectively). The mortality rate was 12/25 (48%) vs. 5/25 (20%), respectively (P = 0.04).
Conclusions: We found a non-significant tendency to higher PCT levels in patients with CDT-positive vs. CDT-negative nosocomial diarrhea. However, a PCT level > 2 ng/ml may help distinguish between these patients.
