Investigating the Factors Affecting the Development of Biliary Pancreatitis and Their Relationship with the Type and Severity of Complications.

BACKGROUND Pancreatitis is an inflammation of the pancreatic tissue. Gallstones are known to be the most common cause of acute pancreatitis, especially in eastern countries, including Iran. Pancreatitis, in its course, can cause complications for the patient. Different systems have been identified as predictors of the severity of acute pancreatitis. As a result, we decided to examine the factors influencing the severity of biliary pancreatitis and their relationship with the complications in Iranian society. METHODS The present study is a cross-sectional, analytical study that was performed retrospectively on 160 patients with biliary pancreatitis. The main and dependent variable in this study is the severity of pancreatitis, which is divided into two groups of complications (local complications and systemic complications) and without complications. The necessary information was extracted from the patients' files and evaluated with SPSS software version 22. RESULTS Based on the results of single-variable analysis, there was a significant relationship between the patient's age, sex, Ranson and CRP criteria, and complication of the disease. In the univariate analysis, no significant statistical relationship was found between patients' BMI(Body Mass Index), CBD (common bile duct) size, serum alkaline phosphatase level, gallstone size, and FBS(Fasting blood sugar), and the complications of the disease, based on the multivariate analysis results. CONCLUSION The results of this study showed that four variables of the female sex, stone size, CRP, and high score of Ranson criteria act as independent risk factors in the development of complicating biliary pancreatitis.

Extra-adrenal, non-functional adrenocortical carcinoma presenting with acute abdomen: a case report.

BACKGROUND: Adrenocortical carcinoma is a rare malignancy, with 43% being non-functional. These may arise from adrenal rest anywhere in the embryonic pathway of the adrenal glands. In the context of extra-adrenal and retroperitoneal tumors, the exact pathologic diagnosis is challenging. The case reported here, to the best of our knowledge, is the seventh reported case of extra-adrenal non-functional adrenocortical carcinoma. CASE PRESENTATION: We report a case of extra-adrenal non-functional adrenocortical carcinoma in a 15-year-old Persian boy who presented with an acute abdomen. He underwent surgical resection. Pathologic findings based on immunohistochemistry and cellular morphology confirmed adrenocortical carcinoma. He was treated with mitotane for 24 months. During a follow-up period of 30 months, no recurrence or metastases were found. CONCLUSION: Despite the rarity of extra-adrenal adrenocortical carcinoma, presentation with an acute abdomen may occur, and the tumor may be found anywhere in the adrenal embryonic pathway. On the other hand, tumor behavior and prognosis in children may be different from what we expect in adults.

Laparoscopic Heller Myotomy for Achalasia: Experience from a Single Referral Tertiary Center.

BACKGROUND Achalasia is the most well known esophageal motility disorder. Laparoscopic Heller myotomy (LHM) is the most effective treatment for achalasia. The aim of this study was to review our results on LHM for achalasia. METHODS In this cross-sectional study all patients undergoing LHM between 2015 and 2017 were studied. The myotomy was followed by an anterior or posterior partial fundoplication. All patients were followed up for at least six months. RESULTS We conducted this prospective study on 36 consecutive patients who underwent LHM over 3 years. The mean age of the patients was 36.64 ± 13.47 years. 30 patients (83.3%) underwent Toupet and 6 patients (16.7%) received Dor fundoplication. 11 patients (30.6%) developed reflux after the procedure. According to the Eckardt Symptom Scoring (ESS), the symptoms improved in 74.2% of the patients and remained unchanged in 25.8% of the patients. Analysis of the ESS, indicated a significant change in regurgitation and retrosternal pain, dysphagia, and weight loss after the surgery (p = 0.001, p = 0.002, p = 0.046, and p = 0.001, respectively). CONCLUSION LHM with anterior or posterior partial fundoplication is safe and achieves a good outcome in the treatment of achalasia, especially in patients who have not responded to other methods while no serious complication was reported despite several prior endoscopic interventions.

Clinical outcome of thymectomy in myasthenia gravis patients: A report from Iran.

Background: Myasthenia gravis (MG) is an autoimmune disease affecting acetylcholine postsynaptic receptor of voluntary muscles. Thymectomy is done in these patients and is a mainstay in the treatment of MG; however, the long-term result of surgery is still controversial. This study dealt with the investigation of the results of thymectomy in treatment, recovery and control of the symptoms of these patients. Methods: This study was performed through a retrospective method in patients suffering from MG who underwent trans-sternal thymectomy between 2011 and 2016. We conducted thymectomy, excision of mediastinal mass and contents of tissues between the right and left phrenic nerves for all patients. Then, the effect of various variables including age, sex, time interval between onset of disease and surgery, thymus pathology and the dosage of drug on clinical response after surgery was determined using various statistical tests. Results: 47 patients including 26 men and 21 women with the mean age of 33.0 ± 4.6 years have been investigated. The mean age of patients was 36.2 and 29.7 in men and women respectively (P = 0.041). Spiral chest computed tomography (CT) scan was present in 47 patients demonstrating mediastinal mass in 40 (85.1%) patients. Also, our pathological results showed thymic cells in aortopulmonary window contents of 4 patients. According to the results, the younger age of patients at the time of surgery, shorter time between diagnosis and thymectomy, being a woman and non-thymoma pathology were along with better clinical outcomes after thymectomy. Conclusion: Our study shows better clinical results of thymectomy in patients with normal chest CT scan and normal or atrophic thymus in pathologic reports. Generally, it seems that performing thymectomy in a shorter time interval after diagnosis of MG is beneficial. Moreover, in MG patients who do not suffer from thymoma, it is along with positive results.

Clavicular Chondrosarcoma: A Case Report and Brief Review of the Literature.

Clavicular bone tumors occur in less than 0.5 percent of bone tumors. Primary chondrosarcoma is very rare even among clavicle tumors. The main symptom is a touchable mass in 69 % of patients. Dedicated centers using FNA and cytology can reach a correct diagnosis in 94% of cases. Treatment planning is done using simple X-ray, CT-scan, shoulder MRI, chest CT-scan and whole body technetium scan. Treatment of choice for primary chondrosarcoma of clavicle is surgical resection.

Esophageal Perforation in a Patient With Kidney Transplantation.

Esophageal perforation is a rupture of the esophageal wall, caused by iatrogenesis in 56% of cases. Perforation of the esophagus remains a challenge, and its incidence has increased as the use of endoscopic procedures has become more frequent. We report a 54-year-old woman with esophageal perforation 8 days after kidney transplantation. She had received a gastrointestinal consultation prior to her transplantation. This report highlights the fact that perforation may occur after any organ transplantation, especially during the initial 2 weeks after transplantation, when mycophenolate mofetil and cyclosporine as well as and high doses of corticosteroid are administered. If there is a delay in passage and a swallowing difficulty, high doses of immunosuppressive drugs are likely to cause ulceration and perforation. Preventive strategies including intravenous steroids for the first 2 to 3 weeks and divided doses of pills should be considered for such patients.

Pulmonary blastoma: a case report and brief review of the literature of tumor-induced hypoglycemia.

BACKGROUND: Tumor induced hypoglycemia (TIH) is a rare clinical entity that can be caused by different mechanisms such as secretion of various substances, autoimmune disorders, massive tumoral infiltration of liver, and pituitary or adrenal glands destruction by tumors. Furthermore, any type of neoplasms can cause TIH. CASE PRESENTATION: The patient presented with a case of classic biphasic pulmonary blastoma (CBPB) with hypoglycemia. Chest CT scan showed 2 huge masses in the right hemi-thorax and multiple smaller masses located in the left hemi-thorax. The patient underwent surgery, and was referred to an oncologist for adjuvant therapy. CONCLUSION: CBPB is a rare primary lung tumor with poor prognosis. They are classically large, symptomatic tumors with lymph node metastasis. Surgical resection at early stages has been more effective than other treatments; however, there is no standard treatment in unresectable cases. Adjuvant treatments have been temporarily effective.
