Role of Bariatric Surgery in Patients With Endometrial Cancer: A Case Report and Review of Literature.

Objective: The standard surgery for endometrial cancer can be deferred in some situations, including morbid obesity, comorbidities, and the patient's desire for fertility. One of the options to improve patients' circumstances is bariatric surgery. Case report: This study presented two patients with stage IA, grade I endometrioid endometrial adenocarcinoma. Both patients had morbid obesity and had comorbidities. In case 1, because of fertility preservation, and in case 2, because of severe comorbidities, hormone therapy was started, followed by bariatric surgery after counseling patients. Both patients had acceptable changes in body mass index during follow-up, so cancer surgery through laparoscopy was done. Both patients did not need adjuvant therapy; months after cancer surgery, there is no recurrence, and their body mass index is also decreasing. Conclusion: Bariatric surgery can improve outcomes in patients with morbid obesity who suffer endometrial cancer.

Acute Pericarditis as the Primary Presentation of COVID-19 Infection followed by Guillain-Barre Syndrome in a Healthy Young Man: A Case Report.

Background: Symptomatic COVID-19 infection most often presents as acute respiratory distress syndrome. Acute pericarditis and Guillain-Barré syndrome are rare extrapulmonary manifestations of this infection. Case Presentation: A 27-year-old man presented with chest pain, with negative troponin and typical electrocardiographic findings, resulting in a diagnosis of acute pericarditis. He had no respiratory symptoms, nor the chest computerized tomography (CT) scan findings of COVID-19, and his Polymerase chain reaction (PCR) was negative. One week later, he developed clinical symptoms of Guillain-Barre syndrome, along with respiratory manifestations of COVID-19. His repeat chest CT scan and PCR test confirmed COVID-19 infection. After 17 days of hospital stay, he improved clinically and was discharged. Conclusion: This is the first case of acute pericarditis as the primary presentation of COVID-19 in the absence of respiratory symptoms and a clear chest CT scan, followed by the development of Guillain-Barré syndrome and respiratory tract manifestations of COVID-19. Clinicians should be aware of the extrapulmonary presentation of COVID-19 infection.

T2* Magnetic Resonance Imaging Study of Pancreatic Iron Overload and its Relation With the Diabetic State in Thalassemic Patients.

The present study was performed to evaluate pancreatic hemosiderosis by means of magnetic resonance imaging (MRI) T2* and its relation to the diabetic state in thalassemic patients. One hundred thirty transfusion-dependent thalassemic patients from Zafar adult thalassemia clinic, Tehran, Iran, were enrolled in the study. Data such as age, type of thalassemia, age at diagnosis, transfusion duration, ferritin level, and fasting blood sugar results were gathered. Pancreatic MRI T2* was performed for all patients. One hundred four thalassemic patients with no sign of diabetes mellitus and 26 thalassemic patients with diabetes mellitus entered the study. Out of a total of 130 patients, 102 had pancreatic hemosiderosis. Among them, 23 of 26 diabetic patients (88.5%) and 79 of 104 nondiabetic patients (76%) showed pancreatic hemosiderosis, indicating no statistically significant difference between the 2 groups. The mean pancreatic MRI T2* relaxation time for all patients was 13.99±12.43 ms. The mean relaxation was 13.62±8.38 and 14.08±13.28 ms for diabetic and nondiabetic patients, respectively, showing no statistical difference (P=0.202). In conclusion, we did not find a significant difference between diabetic and nondiabetic thalassemic patients regarding the MRI T2* relaxation time readings or the rate of pancreatic hemosiderosis. We recommend performing studies with a higher sample size and including patients from different age groups to further evaluate the role of T2* MRI of pancreatic iron overload and its relation with the diabetic state in thalassemic patients.

Analysis of CYP17, CYP19 and CYP1A1 Gene Polymorphisms in Iranian Women with Breast Cancer.

Breast cancer (BC) is the most common cancer and the second cause of mortality in women all around the world. It is caused by several factors including genetic determinants, so that both genetic susceptibility factors and environmental factors are involved in the etiology. Significance of genes functioning in steroid hormone synthesis and metabolism are well established in breast cancer susceptibility. In this study, 134 women with BC and 135 normal controls were analyzed for their genotypes for the polymorphisms, rs743572, rs10046 and rs4646903, resided in CYP17, CYP19 and CYP1A1 genes, respectively. Significant differences in distributions of allele and genotype frequencies were found for the rs10046 polymorphism in CYP19 (p-value=0.01, OR (CI 95%) =1.59 (1.1-2.3), p-value=0.04, OR (CI 95%) =1.7 (1.1-2.5) respectively). For rs743,572 and rs 4646903 polymorphisms, no significant associations were observed. A significant association was observed between the rs10046 polymorphism of the CYP19gene and breast cancer in Iranian patients. Due to inconsistent previous results, more studies in different populations with larger sample sizes are indicated.

The effect of premenstrual syndrome and menstrual phase on postoperative pain.

BACKGROUND: Premenstrual syndrome (PMS) is a common finding in luteal phase of menstrual cycle resulting in several changes in woman life including pain sensation. OBJECTIVES: This study evaluated the alterations of postoperative pain sensation in those with and without a history of PMS. PATIENTS AND METHODS: A total of 140 women in in postoperative period were assigned to four groups regarding luteal or follicular phase of menstrual cycle and the history of PMS and were evaluated regarding scale of pain sensation and morphine demand in recovery room. To evaluate the difference among the groups, Mann Whitney U, Kruskal-Wallis, and Bonferroni tests were used. RESULTS: Patients with PMS presented higher pain sensation and analgesia request (P = 0.003). Patients in luteal phase showed less pain and analgesia request in two out of five studied outcomes (P = 0.075). CONCLUSIONS: The most comfortable postoperative women were those in luteal phase without history of PMS group.

Comparison of crude and age-specific incidence rates of breast, ovary, endometrium and cervix cancers in Iran, 2005.

BACKGROUND: Cancer accounts for 12.6% of total deaths in the world (just after heart disease). MATERIALS AND METHODS: Frequency and age-specific incidence rates of breast and gynecologic cancers in Iran are calculated based on the dataset of the National Cancer Registry of Iran in 2005. RESULTS: Gynecologic and breast cancer accounted for 7.6% and 25.6% of total cancer cases, respectively. Ovarian cancer was the most frequent gynecologic cancer followed by endometrium. Endometrial cancer revealed the highest age specific incidence rate followed by ovary (after 59 years). CONCLUSIONS: Regarding disease burden, breast and gynecologic cases account for 33.4% of total cancer patients. The age specific incidence rate is a useful guide in epidemiologic and future plans.

Comparison of Age- Standard Incidence Rate Trends of Gynecologic and Breast Cancer in Iran and Other Countries.

BACKGROUND: Female cancer, especially breast and gynecologic cancers are considered multistage disease, highly influenced by risk and protective factors and/or screening preventive modalities. Consequences of all these factors result in the trend of change over time. METHODS: In this comparative study, based on data of national cancer registry of Iran 2004 published by Iranian Ministry of Health, age - standard incidence rate (ASR) according to the world population was calculated in all reported gynecologic and breast cancers. Source of all subjects are pathologic based. In the next step, the calculated ASR of Iran and those of the other countries in 2004 were compared to GLOBOCAN ASR reports of 2008. RESULTS: In Iran ASR of breast cancer 2004 (24.93) changed to 18.4 in 2008. Ovarian cancer ASR of 2004, 3.07 was 3.1 in 2008. Endometrial cancer ASR in 2004 (2.29) was 1.7 in 2008. Cervical cancer ASR of 1.71 in 2004 was 2.2 in 2008. CONCLUSIONS: In Iran incidence trend of breast and endometrium are decreasing in the same direction of USA and Australia. Increasing trend of ovary and cervix ASR in Iran is in the inverse direction of USA and Australia which are decreasing. Future studies to find out the same trend or any changes, might develop these findings and improve consequent practical decisions based on results of this study and complementary future studies.

Age - specific incidence rate change at breast Cancer and its different histopathologic subtypes in Iran and Western countries.

OBJECTIVE: The aim of the present study was to determine the frequency and age-specific incidence rate of different histopathologic subtypes of breast cancer in Iran, and compare it to neighboring and Western countries and to discuss the probable effective main factors. METHODS: National data from cancer registry for 6265 female breast cancer patients were studied in 10 histopathologic groups. RESULTS: The most common tumor was ductal carcinoma (89%). The peak age - specific incidence rate of breast cancer in total, and for epithelial, non-epithelial and ductal carcinomas were all 50-59 years, and it decreased in older age. It is in contrast to US SEER report which shows the incidence increases in higher age. CONCLUSION: Three main factors including younger age of Iranian patients, probable more ERN tumors and different histopathological profile of breast cancer in Iran might be considered and studied to explain different slope of breast cancer after menopause compared to other countries.
