Partial Hydatidiform Mole in an Ectopic Tubal Pregnancy.

Fallopian tubal molar pregnancy is extremely rare, and the main diagnostic tool is the post-operative histopathological diagnosis, as the pre-operative diagnosis is difficult. We report a case of ectopic partial molar pregnancy in the right fallopian tube of a 35-year-old lady that was sent for routine histopathological examination with the clinical diagnosis of ectopic pregnancy and the histopathology report revealed an unusual result.

Bariatric surgery and cardiovascular outcome.

BACKGROUND: Obesity is recognized as a classic risk factor for atherosclerosis and subsequent cardiovascular disease (CVD). Weight loss after bariatric surgery has been associated with reduced CV mortality and total mortality in obese patients. Our aim was to study the impact of bariatric surgery on CV risk profile, cardiac structure, and function postoperatively. RESULTS: This prospective longitudinal study included 100 morbidly obese patients at final analysis. All patients were subjected to full clinical, laboratory, and echocardiographic examination at baseline and 6 months after bariatric surgery. The mean age of study population was 37.2 ± 10.49 with BMI of 47 ± 6.82. Females represented 84%. Sleeve gastrectomy and Roux-en-Y gastric bypass were performed in 79% and 21%, respectively. Surgery-related mortality and morbidity were 0.94% and 4.7%, respectively. After 6 months, there were significant decreases in BMI, heart rate, SBP, DBP, and Framingham risk score (P < 0.0001). The prevalence of risk factors decreased as follows: hypertension 24% vs. 12%, P = 0.0005; DM 21% vs. 11%, P = 0.002; dyslipidemia 32% vs. 7%, P < 0.0001; and metabolic syndrome 54% vs. 26%, P < 0.0001. Highly significant (P < 0.0001) decrease in fasting PG and 2 h PP-PG, HbA1c, ASL, ALT, fasting total cholesterol, LDL, TG, and increase in HDL were observed after bariatric surgery. There were significant shortening in QTc interval (P = 0.009), decrease in LV dimensions and LV mass index (P < 0.0001), and increase in LV EF% (P = 0.0003). BMI at follow-up showed significant positive correlation with age, Framingham risk score, and preoperative BMI (r = 0.289, P = 0.0036; r = 0.37, P = 0.0054; and r = 0.31, P = 0.0081, respectively). CONCLUSION: In addition to enabling patients to achieve a substantial weight loss, bariatric surgery provides a myriad of health benefits. Weight reduction was associated with a favorable improvement in cardiovascular risk profile, cardiac structure, and function.

Food Tolerance After Laparoscopic Sleeve Gastrectomy with Total Antral Resection.

BACKGROUND: Among the controversial points in laparoscopic sleeve gastrectomy (LSG) is how much of the antrum to be resected. This study aimed to evaluate food tolerance after preservation or resection of the antrum during LSG. METHODS: Prospective randomized study included 50 patients scheduled for LSG. Participants were randomly allocated into one of two groups. In antral resection (AR-LSG) group (n = 25), resection started 2 cm from the pylorus. In antral sparing (AS-LSG) group (n = 25), it started 6 cm from the pylorus. Percentage of excess weight loss (%EWL) and percentage of excess BMI loss (%EBL) were evaluated after 3 and 6 months. Quality of life (QOL) was evaluated by using the Bariatric Analysis and Reporting Outcome System (BAROS). Food tolerance was assessed using the Quality of Alimentation questionnaire. Primary outcome measure was food tolerance and %EWL. RESULTS: Food tolerance was significantly better in the antral sparing group compared to the antral resection group after 3 and 6 months. The two groups were comparable in %EWL and BMI change after 3 and 6 months. Six months after surgery, the majority of patients had a very good quality of life, with no significant difference between the two groups (p = 0.877). There was no significant difference between the two groups in operative time, intraoperative blood loss, and hospital stay. CONCLUSIONS: Preservation of the pyloric antrum during LSG is associated with significantly better food tolerance and comparable effect of weight loss up to 6 months postoperatively when compared with total antral resection.

Comparative assessment of gastric emptying in obese patients before and after laparoscopic sleeve gastrectomy using radionuclide scintigraphy.

Radionuclide scintigraphy provides a standard physiologic evaluation of gastric emptying (GE) after laparoscopic sleeve gastrectomy (LSG). This operation can be associated with motor gastric dysfunction and abnormal GE. The aim of this study was to evaluate the short-term effect of LSG on GE quantitative indices for liquids and solids compared with preoperative results. Forty obese patients were divided into two equal groups, the liquid and solid groups. Tc-sulfur colloid GE scintigraphy was performed on all patients submitted to LSG before and after surgery (1-4 weeks for liquids and 4-6 weeks for solids). The quantitative indices included half emptying time (T1/2) and percentage gastric retention at 15, 30, and 60 min for liquids and at 30, 60, 90, and 120 min for solids. A modified technique was used to label a boiled egg in order to be tolerated by the patients. T1/2 was significantly enhanced after LSG compared with baseline (25.3±4.4 vs. 11.8±3.0 min for liquids and 74.9±7.1 vs. 28.4±8.3 min for solids, respectively, P<0.001). The percentage of gastric retention in operated patients was significantly less than that at baseline for liquids at 15, 30, and 60 min (33.9±5.6, 17.7±3.9, and 7.5±2.8% vs. 69.4±10.5, 55.6±14.95, and 26.1±4.7%, respectively, P<0.001), as well as for solids at 30, 60, 90, and 120 min (42.0±11.1, 20.8±6.1, 11.0±5.9, and 3.8±2.7% vs. 79.9±8.7, 67.4±12.2, 37.0±10.9%, and 13.8±4.4%, respectively, P<0.001). The significant acceleration of GE of liquids and solids after LSG may have contributed to weight loss in the immediate postoperative period (4-6 weeks). It remains to be determined whether the weight loss will continue beyond that period.

Modifications induced by gamma irradiation to Makrofol polymer nuclear track detector.

The aim of the present study was extended from obtaining information about the interaction of gamma rays with Makrofol DE 7-2 track detector to introduce the basis that can be used in concerning simple sensor for gamma irradiation and bio-engineering applications. Makrofol polymer samples were irradiated with 1.25 MeV (60)Co gamma radiations at doses ranging from 20 to 1000 kG y. The modifications of irradiated samples so induced were analyzed using UV-vis spectrometry, photoluminescence spectroscopy, and the measurements of Vickers' hardness. Moreover, the change in wettability of irradiated Makrofol was investigated by the contact angle determination of the distilled water. UV-vis spectroscopy shows a noticeable decrease in the energy band gap due to gamma irradiation. This decrease could be attributed to the appearance of a shift to UV spectra toward higher wavelength region after irradiation. Photoluminescence spectra reveal a remarkable change in the integrated photoluminescence intensity with increasing gamma doses, which may be resulted from some matrix disorder through the creation of some defected states in the irradiated polymer. The hardness was found to increase from 4.78 MPa for the unirradiated sample to 23.67 MPa for the highest gamma dose. The contact angle investigations show that the wettability of the modified samples increases with increasing the gamma doses. The result obtained from present investigation furnishes evidence that the gamma irradiations are a successful technique to modify the Makrofol DE 7-2 polymer properties to use it in suitable applications.
