Managing hyperemesis gravidarum: a multimodal challenge

Up to 90% of pregnant women experience nausea and vomiting. When prolonged or severe, this is known as hyperemesis gravidarum (HG), which can, in individual cases, be life threatening. In this article the aetiology, diagnosis and treatment strategies will be presented based on a selective literature review. Treatment strategies range from outpatient dietary advice and antiemetic drugs to hospitalization and intravenous (IV) fluid replacement in persistent or severe cases. Alternative methods, such as acupuncture, are not yet evidence based but sometimes have a therapeutic effect

Osseous metaplasia of the endometrium

PubMedID: 22766572Osseous metaplasia of the endometrium is very rare finding, and usually these cases presented with secondary infertility. Other symptoms are pelvic pain, dyspareunia, menstrual irregularities, vaginal discharge and the passage of bony fragments in menstrual blood. Suspicious lesion could see by hysterosalpingography or by ultrasonography; however, conclusive diagnosis and treatment tool is hysteroscopy. The aetiology is unknown, but theories include retained fetal bone and osseous metaplasia of endometrial tissue. We present a patient with osseous metaplasia who had treated with hysteroscopy

Storing tooth segments for optimal esthetics

Objective: A fractured whole crown segment can be reattached to its remnant; crowns from extracted teeth may be used as pontics in splinting techniques. We aimed to evaluate the effect of different storage solutions on tooth segment optical properties after different durations. Study design: Sixty central incisor crowns were divided into 6 groups (n = 10); Group 1 was kept dry; Groups 2, 3, 4, 5, and 6 were placed in an isotonic solution, water, milk, saliva, and casein-phosphopeptide–amorphous-calcium-phosphate (CPP–ACP), respectively, for 30 min, 12 h, 1 day, 1 week, and 3 weeks. Color values were measured using a colorimeter. Data were analyzed with Kruskal–Wallis tests, Mann–Whitney U-tests, and Friedman Wilcoxon tests with Bonferroni stepwise corrections (p 0.01). Comparing ΔE* values, Group 6 was significantly different from the other groups for all durations (p < 0.01), except Group 4. Conclusions: A CPP–ACP complex solution seems a good choice for tooth fragment storage. Milk and saliva solutions may cause perceptible color changes if tooth fragments are stored for 3 weeks before use

ABC Algorithm based Fuzzy Modeling of Optical Glucose Detection

This paper presents a modeling approach based on the use of fuzzy reasoning mechanism to define a measured data set obtained from an optical sensing circuit. For this purpose, we implemented a simple but effective an in vitro optical sensor to measure glucose content of an aqueous solution. Measured data contain analog voltages representing the absorbance values of three wavelengths measured from an RGB LED in different glucose concentrations. To achieve a desired model performance, the parameters of the fuzzy models are optimized by using the artificial bee colony (ABC) algorithm. The modeling results presented in this paper indicate that the fuzzy model optimized by the algorithm provide a successful modeling performance having the minimum mean squared error (MSE) of 0.0013 which are in clearly good agreement with the measurements
