Reconstruction of the alveolar cleft: effect of preoperative extraction of deciduous teeth at the sites of clefts on the incidence of postoperative complications

Our objective was to find out if the extraction of deciduous teeth at the sites of clefts 3-8 weeks before alveolar bone grafting (ABG) would reduce the number of postoperative complications. Chart reviews were reviewed retrospectively of patients who had had ABG from March 2006 to June 2009. To reduce variables only healthy, non-syndromic, cooperative patients were included. Eleven patients had had their deciduous teeth extracted at the cleft sites 3-8 weeks before ABG and 10 patients had had the extractions done intraoperatively at the same time as ABG. There was a single case of postoperative infection and no wound dehiscence in the preoperative extraction group, and there were no delays in postoperative orthodontic treatment. In the intraoperative group there were 3 cases of local wound infection and 6 cases of minor dehiscence, and orthodontic treatment was delayed for 3-6 months in all patients with complications. All patients had successful ABG, eruption of teeth, and orthodontic treatment; but patients who had their deciduous teeth at the cleft sites extracted preoperatively had fewer wound complications than patients whose extractions were done at the same time as the ABG.     

Impact of Aggressive Histology and Location of Primary Tumor on the Efficacy of Surgical Therapy for Peritoneal Carcinomatosis of Colorectal Origin

Background

Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemoperfusion (HIPEC) for peritoneal carcinomatosis (PC) of colorectal origin increases survival (OS) compared to systemic chemotherapy alone. Signet ring histology demonstrates aggressive behavior with poor survival. We sought to determine whether CRS/HIPEC increases survival in this subset of patients.

Methods

We reviewed 67 patients with PC of appendiceal (AP, n = 37) or colorectal origin (CRC, n = 30) with signet cell histology from a prospective database between May 2001 and August 2011. Survival analysis and multivariate Cox regression were used to determine prognostic factors for survival.

Results

Complete CRS (CC-0/1) was achieved in 77 % (CRC) and 73 % (AP) of patients. Progression-free survival (PFS) and OS were 9 and 12 months in CRC and 12 and 21 months in AP patients. In the CRC group, univariate predictors of poor survival included female gender, age, American Society of Anesthesiologists score, preoperative albumin, completeness of cytoreduction, and morbidity. In a multivariate Cox regression model, incomplete cytoreduction (CC-2/3) and female gender were joint significant predictors of poor survival. In the AP group, significant univariate predictors of poor survival included higher EBL and PCI score. In a multivariate Cox regression model, blood loss of >500 ml and a body mass index of <25 kg/m² were joint significant predictors of poor survival.

Conclusions

AP signet cell tumors demonstrate a more favorable outcome than CRC signet cell tumors after CRC/HIPEC for carcinomatosis, suggesting an underlying difference in biology. CRS/HIPEC does not confer survival benefit in colorectal signet ring carcinomatosis unless complete cytoreduction can be achieved, whereas appendiceal signet ring carcinomatosis may benefit, regardless of resectability.     

Diabetes mellitus,metabolic syndrome,and physical activity among Ethiopians: A systematic review

Background and aimsThe incidence of diabetes mellitus (DM) is increasing worldwide, and there is growing appreciation for the impact of limited physical activity on the disease. This study aimed to determine whether the current research on DM in Ethiopia has sufficiently identified and focused on the importance of limited physical activity according to the Global Physical Activity Questionnaire (GPAQ) in the disease etiology.MethodsThis was a systematic review, performed according to the PRISMA checklist. We searched primary studies of diabetes, diabetes-related complications, determinants, and magnitude of related morbidities in Ethiopia in PubMed, Medline, and ISI Web of Science databases. Reviews, editorial communications, reports, and letters were excluded.ResultsAmong 363 articles that were identified from all databases, 28 were included. It was found that 39% of the studies measured and included limited physical activity as a predisposing lifestyle factor in diabetes, while 17.86% either did not report or did not include this variable at all. Although 42.86% of the studies identified limited physical activity as an etiological factor in diabetes, it was not measured according to the GPAQ guidelines.ConclusionsThese data suggest that Ethiopian researchers do not give sufficient attention to the role of physical activity and its definition per GPAQ as a preventative factor for reducing the severity of diabetes symptoms. We suggest that physical activity research and promotion should be advocated in Ethiopia, and that researchers should seek advice on how to re-frame their work in the future.     

Percutaneous transluminal coronary angioplasty of a right coronary artery arising from the left main coronary artery

Angioplasty of anomalous coronary arteries presents unique technical challenges. Correct guiding catheter selection is important to ensure adequate access to the anomalous vessel and to provide support to cross the lesion. A case of successful PTCA of a lesion in an anomalous right coronary artery arising from the left main coronary artery is presented. © 1993 Wiiey-Liss, Inc.     

Impact of elevated glycosylated hemoglobin on hospital outcome and 1 year survival of primary isolated coronary artery bypass grafting patients

Objective

It is unknown whether adequacy of diabetic control, measured by hemoglobin A1c, is a predictor of adverse outcomes after coronary artery bypass grafting.

SSRIs for Hot Flashes: A Systematic Review and Meta-Analysis of Randomized Trials

Background

Hot flashes are the most commonly reported vasomotor symptom during the peri- and early post-menopausal period.

Objectives

To systematically review, appraise and summarize the evidence of the impact of different SSRIs on peri-menopausal hot flashes in healthy women in randomized, controlled trials.

Methods

A comprehensive literature search was conducted of MEDLINE?, EMBASE, the Cochrane Central Register of Controlled Trials, Web of Science and Scopus through March 2013. Two independent reviewers selected studies and extracted data. Random effects meta-analysis was used to pool outcomes across studies, and Bayesian mixed treatment methods were used to rank SSRIs in terms of effectiveness.

Results

We included a total of 11 randomized controlled trials with good methodological quality enrolling 2,069 menopausal and post-menopausal women (follow-up 1–9 months, mean age 36–76 years, mean time since menopause 2.3–6.6 years). Compared with placebo, SSRIs were associated with a statistically significant decrease in hot flash frequency (difference in means ?0.93; 95 % CI ?1.46 to ?0.37; I² = 21 %) and severity assessed by various scales (standardized difference in means ?0.34; 95 % CI ?0.59 to ?0.10; I² = 47 %). Adverse events did not differ from placebo. Mixed treatment comparison analysis demonstrated the superiority of escitalopram compared to other SSRIs in terms of efficacy.

Conclusion

SSRI use is associated with modest improvement in the severity and frequency of hot flashes but can also be associated with the typical profile of SSRI adverse effects.
