Positive diagnosis of diabetes is currently easy, but typing diagnosis of diabetes still remains a challenge for every clinician. It is currently accepted that types of diabetes apart from T1D and T2D can expand and include several forms of diabetes mellitus;From gestational diabetes, to all forms of secondary diabetes mellitus due to medications, intercurrent disease but also infections, and finally monogenic diabetes, whose diagnosis is not always easy to establish. The aim is to reveal the difficulties that clinicians may face in the process of etiological diagnosis regarding the suspicion of this type of monogenic diabetes, through the study of 2 cases, in which MODY type diabetes was suspected. Today we recognize 17 different genetic mutations that can all lead to MODY diabetes, the most common mutation of which is GCK coding for the glucokinase, the real sensor of pancreatic Beta-cell. The truly stable glycemic profile, with an A1C ranging between 7% and 7.5%, confirmed with a TIR always above 70% and a good MAGE, but also the rarity of degenerative complications and pharmacological therapeutic abstention which can last for years, these would be the most striking clinical characteristics of a GCK MODY.

Objective To explore if the addition of adjuvant chemotherapy with paclitaxel and carboplatin to radiotherapy confers an advantage for overall survival （OAS）, and progression free survival （PFS）; to assess the incidence of relapses over standard pelvic radiotherapy; and to evaluate the related toxicity in high-risk stage I-II endometrial carcinoma Methods Medical records were reviewed to identify high-risk stage I-1I endometrial carcinoma cases treated in the Clinical Oncology and Nuclear Medicine department between 2002 and 2008 with adjuvant radiotherapy alone （arm Ⅰ）（57 patients） or with sequential carboplatin （AUCS-6） and paclitaxel （135-175 mg/m^2） with radiotherapy （arm Ⅱ）（51 patients）. Radiotherapy was performed through the four-field box technique at doses of 45-50 Gy （1.8 Gy/day × 5 days/week）. Results The toxicity was manageable and predominantly hematologic with a grade 3 neutropenia and thrombocytopenia in 9.8% and 6% of the patients in arm Ⅰ and arm Ⅱ, respectively, without febrile neutropenia. All patients experienced hair loss. Chernoradiotherapy arm was associated with a lower incidence rate of relapse （9.8% vs. 22.7%）. After a median follow-up period of 48 months, the 5-year OAS and PFS rates for chemoradiotherapy-treated patients were significantly more favorable than those who did not receive chemotherapy （P=0.02 and 0.03, respectively）. In arm I, the OAS and PFS rates were 73.7% and 66.7% compared with those in arm II, whose rates were 90.2% and 84.3%. Conclusions Adjuvant chemoradiation with paclitaxel and carboplatin improved the survival rates and decreased the recurrence rates in patients with high-risk stage Ⅰ-Ⅱ endometrial carcinoma. Chemotherapy was associated with an acceptable rate of toxicity. However, a prospective study with a larger number of patients is needed to define a standard adjuvant treatment for high-risk stage Ⅰ-Ⅱ endometrial carcinoma.

In this paper, the Adomian’s decomposition method has been developed to yield approximate solution of bacterial chemotaxis model of fractional order in a semi-solid medium. The fractional derivatives are described in the Caputo sense. The method introduces a promising tool for solving many linear and nonlinear fractional differential equations.

Background: This study discusses the effect of obesity on the number of lymph nodes harvested during systematic LND and the LND-related complications in ovarian cancer patients. Methods: This retrospective study enrolled women with ovarian cancer who were consecutively subjected to open surgical resection that included systematic LND (pelvic and para-aortic) in the Oncology Center in Mansoura University (OCMU) during the period between January 2012 and June 2017. Patients were categorized according to the recommendations of World Health Organization by their BMI as non-obese (BMI 30.0 kg/m2) and obese (BMI ≥ 30.0 kg/m2). Results: Seventy-seven women with ovarian cancer were enrolled in the study according to our inclusion and exclusion criteria. 43 females (55.8%) were grouped as obese and 34 (44.2%) as non-obese. Lymph nodes retrieved in total and in different stations separately (pelvic and para-aortic) were all similar among patients in both groups. LND-related intraoperative complications were observed in 8 patients (18.6%) in the obese group and 3 patients in the non-obese group (8.8%) (P = 0.347). Hospital stay was the same in the two groups with a median of 4 days (IQR 3 - 5). Postoperative complications occurred in 13 patients (30.2%) in the obese group and only in one patient (3%) in the non-obese group (P = 0.004). Conclusion: Obese ovarian cancer patients may safely undergo comprehensive staging involving extensive lymph node dissection in open surgeries without significant increase in the rates of intraoperative complications. Whereas, postoperative complications (wound infection and thromboembolic events) tend to occur at higher rates with obese patients. Trial registration: This study was retrospectively registered and approved at faculty of Medicine Mansoura University, Egypt with IRB approval number R.18.02.46.

Background: Frozen section (FS) has a valuable role in the diagnosis of ovarian tumors. It is considered a pivotal point in guiding the surgical therapy, particularly in premenopausal women. In postmenopausal women, it may be required as well to avoid unnecessary surgical staging in benign ovarian tumors. Aim: This study aims to evaluate the accuracy of intraoperative frozen section in ovarian neoplasms in postmenopausal women. Materials and Methods: A retrospective analysis was done for intraoperative FS for suspected ovarian neoplasms. The study was conducted in Oncology Center, Mansoura University from March 2008 to December 2014. The frozen and paraffin section reports were compared, and overall accuracy, sensitivity, specificity, positive and negative predictive values were determined. Results: The study included 105 patients and the overall accuracy of FS in determining malignancy was 81.7%. The sensitivity for malignant tumors was 75.32% with specificity of 100%. For benign tumors, the sensitivity and specificity were 100% and 93%, respectively. Borderline tumors had the lowest sensitivity of 100% with specificity of 95.19%. Conclusion: The present study concurs that frozen section is an accurate test for diagnosis of benign and malignant tumors in postmenopausal women thus determining the extent of surgery done for them. On the other hand, accuracy rates for borderline tumors are low.

The ethanol, chloroform and acetone extracts of five species from Acacia (Acacia albidia stems, Acacia mellifera aerial parts, Acacia nubica aerial parts, Acacia seyal var. seyal stems and Acacia tortilis aerial parts) were investigated for their antimicrobial activity against two standard bacterial strains of Gram +ve bacteria (Staphylococcus aureus (ATCC 25923)), Gram -ve bacteria (Pseudomonas aeruginosa (ATCC 27853)) and standard fungi Candida albicans (ATCC 90028) using the agar-plate well diffusion method. The chloroform extract was inactive compared to ethanol and acetone extracts. But ethanol extracts showed the maximum antimicrobial activity against the test organism. Amongst the plant species screened, ethanol extract of Acacia seyal stems showed maximum inhibitory activity (38 mm) and (37 mm) against Staphylococcus aureus and Candida albicans, respectively. The ethanol, chloroform and acetone extracts of Acacia mellifera (aerial parts) did not show any activity against the test organisms. Cholorophorm and acetone extracts via DPPH, the radical scavenging activities were found to be 91 ± 0.03, 88 ± 0.01 and 85 ± 0.04, respectively. The results of phytochemical screening showed that all extracts of studied plant contain flavonoids, saponins, terpenoids, steroids, alkaloids, phenols and tannins.
