Bilateral lower extremity arterial thromboembolism mimicking conversion disorder

Thromboembolic causes of acute limb ischemia are not frequent; however, an immediate true therapy is needed to save the extremity. Here we presented a case with bilateral lower extremity arterial thromboembolism mimicking conversion disorder. Conversion disorder and acute arterial embolism can be confronted in different patterns. This case proved us that anamnesis can be misleading and manipulating to evaluate patients. Furthermore, our report may potentially highlight the inadequacies in the guidelines for diagnosis.     

Evaluation of Serum microRNA Let-7c and Let-7d as Predictive Biomarkers for Metastatic Pancreatic Cancer

Background:First-line treatments for metastatic pancreatic cancer are chemotherapy regimens consisting of 5-fluorouracil or gemcitabine; however, there are no biomarkers to help determine which patients might benefit from which treatment regimens. We aimed to show that microRNAs let-7c and 7d can be used as independent predictive biomarkers for metastatic pancreatic cancer.Methods:A total of 55 patients who had first-line chemotherapy with FOLFIRINOX or gemcitabine + capecitabine were included. Patients were divided into groups based on let-7c and let-7d levels and chemotherapy treatment as let-7c-7d high FOLFIRINOX, let-7c-7d high gemcitabine + capecitabine, let-7c-7d low FOLFIRINOX, and let-7c-7d low gemcitabine + capecitabine. Blood samples were taken from patients before chemotherapy for microRNA let-7c and 7d analysis. MicroRNA isolation was performed using a miRNeasy Serum/Plasma Kit and identified using spectrophotometric measurements. After isolation, microRNA was converted to cDNA using a microRNA cDNA Synthesis Kit with poly (A) polymerase tailing. The expression of microRNA was examined using quantitative real-time polymerase chain reaction.Results:The overall survival of patients who received FOLFIRINOX treatment with a high let-7c-7d level was statistically significantly longer than those who received gemcitabine + capecitabine with a high let-7c-7d level. In addition, patients with low let-7c expression receiving FOLFIRINOX progressed significantly 2.104 times earlier than patients with high let-7c expression receiving FOLFIRINOX.Conclusion:The serum MicroRNA let-7c level was found to be an independent predictive biomarker in the FOLFIRINOX treatment group.     

Comparison of short- and long-term outcomes of bariatric surgery methods: A retrospective study

The present study is intended to retrospectively compare the short- and long-term outcomes of 3 different treatment methods in patients undergoing bariatric surgery and the variances in weight and nutritional parameters during the preoperative and postoperative periods. In this study, 534 patients who underwent laparoscopic sleeve gastrectomy (LSG), laparoscopic Roux-En-Y gastric bypass (LRYGB), and laparoscopic one anastomosis gastric bypass (LOAGB) between 2014 and 2021 were included. The sociodemographic and biodemographic characteristics of these patients, their weight losses and nutritional changes in the preoperative and postoperative periods, operative times, hospital stays, complications, and morbidity and mortality rates were retrospectively compared. There was a statistically significant difference between the surgical methods in the percentages of excess weight loss and total weight loss in the 1st and 3rd months. There were significant differences in the homeostasis model assessment of insulin resistance, folic acid, vitamin D, iron, ferritin, and parathyroid hormone levels (P < .05). All 3 techniques were found to be successful in facilitating weight loss at the end of the first year. LRYGB and LOAGB were found to be superior to LSG in terms of remission from diabetes during the first 6 months, whereas LSG was superior to the other methods in terms of nutritional deficiencies. Despite being more advantageous in terms of operative time, LSG and LOAGB were disadvantageous compared with the LRYGB technique because of the higher rates of leakage and mortality in the LSG technique and the higher rate of bile reflux in the LOAGB technique.     

Evaluation of the Cardiovascular Risk in Patients with Subclinical Cushing Syndrome Before and After Surgery

Background The widespread use of ultrasound, computerized tomography, and magnetic resonance imaging has led to an increase in the number of incidental adrenal masses identified. Asymptomatic incidentally discovered adrenal masses may indicate that subclinical Cushing syndrome (SCS) is not uncommon. We aimed to evaluate the cardiovascular risk of patients with SCS before and after surgery. Methods An autonomous cortisol-producing tumor was detected in 11 of 94 patients with adrenal incidentaloma between 1995 and 2005. Twenty-eight patients suffering from classical Cushing syndrome (CS) associated with unilateral adrenocortical adenoma, who were treated at our department in the same period, served as a control group. Cardiovascular risk factors such as blood pressure, body mass index, and lipid profile were evaluated before and 1 year after surgery. Results The frequency of hypertension (61% versus 63%), obesity (46% versus 55%), diabetes mellitus (50% versus 36%), hypercholesterolemia (39% versus 36%), and low HDL cholesterol (28% versus 36%) were not significantly different between CS and SCS patients, respectively. Adverse cardiovascular risk profile improved 1 year after adrenalectomy in both groups, although the changes were not significant with respect to body mass index, frequency of diabetes, and hyperlipidemia in SCS patients. But frequency of systolic/diastolic hypertension decreased significantly in this group. Conclusions These findings indicate that the increased incidence of cardiovascular risk factors commonly observed in classical CS, is also present in SCS. Unilateral adrenalectomy does not always lead to significant improvements in cardiovascular risk profile in SCS.     

Endometriotic umbilical port site metastasis after laparoscopy

We present the case of a 40-year-old woman who had been previously operated for endometrioma 2 years ago by laparoscopy, with the complaint of an umbilical mass with cyclical pain pattern. The dark-colored mass was excised and pathology report revealed it to be an endometriotic implant.     

Fetal MRI of a severe Dandy-Walker malformation with an enlarged posterior fossa cyst causing severe hydrocephalus

We present a case of severe Dandy-Walker malformation with enlarged posterior fossa cyst extruding through the incisura of the tentorium and causing severe hydrocephalus. A posterior fossa malformation was suspected by ultrasonography and was further evaluated by fetal magnetic resonance imaging (MRI). Fetal MRI demonstrated that there were no associated anomalies and the decision was made to continue with labor instead of terminating the pregnancy. The precise diagnosis and absence of associated anomalies revealed by MRI aided in parent counseling and obstetrical management.     

Thyroid metastasis of malignant melanoma

Clinically significant metastases to the thyroid gland are very rare; however, they can present as the initial malignancy. The authors report a 53-year-old man who underwent surgery for malignant melanoma 5 years earlier, and recently presented with a thyroid nodule that turned out to be a metastasis of the primary malignancy. Fine-needle aspiration showed malignant cells, but was unable to indicate that their origin was malignant melanoma. Total thyroidectomy was the therapy chosen for the patient.
