Introduction: Secondary lymphedema is one of the major important long-term complications of breast cancer treatment. The aim of this study is to determine patient- and treatment-related risk factors of lymphedema in breast cancer patients. Patients and Methods: Patients, who had been operated on for primary breast cancer at Akdeniz University Hospital and followed regularly between August 1984 and December 2009 were included in the study. In order to evaluate the arm swelling objectively, measurements were performed with a flexible tape measure for both arms, and limb volume was calculated using a truncated cone volume formula. Participants, whose volume difference between the two arms was ≥5%, were considered as lymphedema-positive patients. The SPSS program (SPSS inc. Chicago, IL) was used for statistical analysis. Results: The mean age of 455 patients was 50.6 years and the median follow-up time was 53 months. Lymphedema was found in 124 (27%) patients. Most of the patients with a history of postoperative wound infection (52%) and lymphangitis (57%) had lymphedema ( p =0.003 and p =0.002, respectively). Addition of radiation therapy increased lymphedema risk 1.83 times ( p =0.007). The mean duration of the axillary drainage and number of the removed lymph nodes were 7.8 days and 19, respectively. The rate of lymphedema in patients with early stage breast cancer was less than patients with advanced breast cancer (24% and 35.3%, respectively, p =0.018). Most of the patients (92%) with lymphedema had a high body mass index (BMI ≥25 kg/m 2 ), and obesity was another important factor for lymphedema ( p <0.001). Conclusions: The most important treatment and patient-related risk factors for breast cancer-related lymphedema were obesity (≥25 kg/m 2 ), axillary lymph node dissection, postoperative radiotherapy, wound infection, history of lymphangitis, and duration of axillary drainage. Elimination or prevention of these risk factors may reduce the incidence of lymphedema.

Loss of gastrointestinal motility occurs for patients who experience abdominal surgery and in order to avoid postoperative nausea and vomiting a period of fasting is commonly practiced. This study presents a system which acquires bowel sound signals by means of a devised stethoscope, performs real-time signal processing and notifies clinicians if bowel activity is present. The idea behind this practice is to provide enough time for intestinal motility to return to normal and benefit from early feeding in order to shorten hospital stay. Research findings indicate that a detection algorithm using statistical approach is suitable for real time monitoring in noisy clinical environments.

Adrenal incidentalomas (AI) are adrenal masses that are discovered during radiological examinations conducted for other reasons. In this study, we focused on the pathological and radiological properties of nonfunctional AI(NFAI) and the association with malignancy risk in our clinical series. A total of 186 patients underwent adrenalectomy between 2010 and 2017; of these, 76 (40.8%) patients with non-functional AI were included in the current study. The radiological and pathologic characteristics of these AIs were retrospectively analyzed to determine the malignancy rate. There were 22 (28.9%) male and 54 (71.1%) female patients with nonfunctional AI included in this study. The median age was 55 (range: 24-85) years. Of the patients included, 37 (48.6%) had AI on the left and 39 (51.3%) had AI on the right adrenal gland. Sixty-one (80.2%) cases were treated laparoscopically, four (5.3%) required conversion to open surgery due to intraoperative difficulties such as bleeding and adhesions, and 11 (14.4%) were managed with open adrenalectomy. The rate of malignancy in the tumors with diameters of 6 cm was found to be 0%, 2.9%, and 13.6%, respectively. Determining the ideal cutoff value for surgical indication in an NFAI is challenging. Besides the malignancy risk, the rate of silent pheochromacytomas must be taken into account in the surgical decision.

Background: There is little knowledge with regard to the management of intestinal failure in countries where home care services and dedicated intestinal rehabilitation centers are limited. This study presents a single-center experience of treating adult-type short bowel syndrome (SBS) with serial transverse enteroplasty (STEP). Methods: Medical records were retrospectively reviewed from November 2009 to April 2018 on patients with adult-type SBS. All patients underwent STEP, and a representative quota sample of control patients treated with conventional measures were included. Clinico-demographic characteristics including baseline and post-treatment information about the orientation of bowel alignment and nutritional status were evaluated. Results: The mean patient age was 51.1 ± 16.2 in the STEP group and 57.6 ± 12.7 in the control group (P = .304). The median small bowel length was 60 cm (interquartile range (IQR): 40-90) in the STEP group (before the lengthening) and 90 cm (IQR: 70-100) in the control (at the initiation of intestinal rehabilitation) (P = .035). Durations of median follow-up were 18 months (IQR: 14-58) and 10 months (IQR: 3-14), respectively (P = .019). In the STEP group, the mean increase in bowel length after STEP was 37.3 ± 11.6 cm, and at their follow-up 7 patients (64%) had successfully progressed to enteral autonomy. In the control group, only 3 patients (27%) were successful. Mean time to wean parenteral nutrition was 45 ± 54 days, and the mean increase in enteral calorie intake was 1.79 ± 1.60-fold after lengthening in the STEP group. Conclusions: STEP is an easy-to-perform procedure in the surgical rehabilitation of adult-type SBS. When performed simultaneously with reconnection surgery, it may offer a cost-effective and comprehensive solution to the treatment strategy in middle income settings.
