Background This study identifies the incidence of appendiceal Enterobius vermicularis (E.v) infestation in all the patients undergoing appendectomy and evaluates the relationship between E. v infestation of the appendix and the acute appendicitis. Method ology: All the routinely examined appendectomy specimens received in the pathology laboratory of a referral hospital over a three year period of time were reviewed for the existence of E. v. These cases were evaluated for clinico-laboratory characterization. Results Out of 1150 appendectomies for clinical acute appendicitis picture, 31 (2.7%) cases revealed E. v infestation. The age ranged from 6 to 42 years old but more than 80% of the E. v infected cases were children. Twenty four cases (77.4%) did not show any other appendiceal pathology, six cases showed lymphoid hyperplasia and only one case showed concomitant histological acute inflammatory process. Conclusion E. v infestation is an incidental finding during histopathology examination of appendectomy specimens for patients with clinical diagnosis of acute appendicitis, however there is no relation between the existence of E. v and occurrence of acute appendicitis which is the main indication for appendectomy, so further studies are recommended to reach out earlier diagnosis to eliminate the unnecessary surgical intervention. Also surgeons should consider E. v as a differential diagnosis when removing a normal looking appendix to take the necessary precautions for minimizing any chance of contamination and sending all the normal looking appendectomy specimens for histopathology examination.

Background: The surgical operation of Bariatric is taken into consideration to be the best treatment for excessive obesity. The prime requirement for the broad usage of bariatric surgical treatment is the durability. This study compares the weight variation up to five years between patients treated by RYGB (Roux-en-Y Gastric Bypass) and non-surgical methods. Methods: The current work is a retrospective cohort study which was performed on one hundred patients who subjected to RYGB surgical treatment and matched severely obese controls that had not treated by bariatric surgery in the period from 2011 to 2015 and completed five years follow up. Results: The differences between the two study groups were significant according to their loss in weight within a five years record. More than 90% of Patients were satisfied inside the RYGB group versus a percent of 4% in Non-surgical Matches group with a great significant difference. Conclusion: The concluded results confirm that bariatric surgical treatment is the handiest and giving the best results in reducing enormous excess weight in patients with sharp obesity. These effects provide additional proof of the valuable combination between direct loss of weight by surgery and long-term methods. Highlights

Background Bariatric surgical operation is taken into consideration to be the handiest remedy for extreme obesity. Durability is the main requirement for the broad usage of bariatric surgery. According to several factors, the present work tries to match the SG and RYGB techniques. Methods This is a retrospective work that studied 200 morbid obese patients randomized and categorized into two groups according to the treatment method: the laparoscopic sleeve gastrectomy (LSG) and LRYGB groups, within the period from 2014 to 2019 and matched weight dissipation, complications, quality of life, and adverse events. Results BMI had a mean value of 39.66 ± 3.770 kg/m2 in the RYGB group versus 39.38 ± 3.648 kg/m2. No significant differences were found according to comorbidity, height, and weight. There was no significant difference between the study groups according to complications and morbidity—no recorded unexpected histopathology results in the excised LSG specimens. Conclusion There was no significant change in weight dissipation, fluctuations in comorbidities, increase in Quality of Life (QoL), and complications for pathological obesity patients according to the treatment methods of laparoscopic SG (sleeve gastrectomy) and RYGB at 2-years postoperative follow-up.

Background. Although hyperfunctioning thyroid disorders were thought to be protective against malignancy, some recent studies reported a high incidence of incidentally discovered cancer in patients with hyperfunctioning benign thyroid disorders. We performed this study to estimate the incidence and predictors of malignant thyroid disease in patients with toxic nodular goiter (TNG). Patients and Methods. The data of 98 patients diagnosed with TNG were reviewed (including toxic multinodular goiter SMNG and single toxic nodule STN). The collected data included patients age, gender, systemic comorbidities, family history of thyroid malignancy, previous neck radiation, type of disease (multinodular or single), size of the dominant nodule by the US, operative time, and detection of significant lymph nodes during operation. Based on the histopathological analysis, the cases were allocated into benign and malignant groups. Results. Malignancy was detected in 21 patients (21.43%). Although age distribution was comparable between the two groups, males showed a significant increase in association with malignancy. Medical comorbidities and family history of cancer did not differ between the two groups. However, TMNG showed a statistically higher prevalence in the malignant group. Operative data, including operative time and lymph node detection, were comparable between the two groups. On regression analysis, both male gender and TMNG were significant predictors of malignancy. Conclusion. The presence of thyroid hyperfunction is not a protective factor against malignancy, as malignancy was detected in about 1/5 of cases. Male gender and TMNG were significant risk factors of malignancy in such patients.
