Multicenter Study of Robotic Thyroidectomy: Short-Term Postoperative Outcomes and Surgeon Ergonomic Considerations

Background  

Robotic thyroidectomy (RT) has recently emerged as a viable approach to thyroid surgery, resulting in better functional and cosmetic outcomes than afforded by open thyroidectomy (OT). The present multicenter study assessed the perioperative outcomes of RT and compared physician perspectives on the musculoskeletal ergonomic parameters associated with OT, endoscopic thyroidectomy (ET), and RT.     

Neurogenic Detrusor Overactivity in Patients With Spinal Cord Injury: Evaluation and Management

Lower urinary tract dysfunction can have a significant impact on patients with spinal cord injury. Over the years, many treatment options have become available. This article reviews the assessment and management of neurogenic detrusor overactivity, with a particular focus on articles from the recent literature. Recent guidelines on the subject will be discussed. Management options include antimuscarinics and bladder emptying measures, botulinum toxin A, and neuromodulation in refractory cases and surgery for intractable cases. Recent and relevant publications in these areas will be summarized and discussed.     

Cricopharyngeal myotomy for primary cricopharyngeal dysfunction caused by a structural abnormality localized in the cricopharyngeus muscle: Report of a case

Primary cricopharyngeal dysfunction (PCD) is a rare idiopathic disorder of the upper esophageal sphincter (UES), characterized by oropharyngeal dysphagia, frequent aspiration, and narrowing at the level of the UES. Cricopharyngeal myotomy (CPM) has been used to treat oropharyngeal dysphagia of different causes including anatomic, neuromuscular, iatrogenic, inflammatory, neoplastic, and idiopathic; however, the indications for CPM and predictors of its outcome are not clearly defined. We report a case of PCD with hypertonic UES caused by a structural abnormality localized in the cricopharyngeus muscle, visualized as a cricopharyngeal bar, which we treated successfully by CPM, achieving long-term relief.     

Wnt5a as an Effector of TGFβ in Mammary Development and Cancer

Wnt5a is a member of the Wingless-related/MMTV-integration family of secreted growth factors, which are involved in a wide range of cellular processes. Wnt signaling can be broadly divided into two categories the canonical, ß-catenin-dependent pathway and the non-canonical ß-catenin-independent pathway. Wnt5a is a non-canonical signaling member of the Wnt family. Loss of Wnt5a is associated with early relapse of invasive breast cancer, increased metastasis, and poor survival in humans. It has been shown that TGF-ß directly regulates expression of Wnt5a in mammary gland and that Wnt5a mediates the effects of TGF-ß on branching during mammary gland development. Here we review the evidence suggesting Wnt5a acts as an effector of TGF-ß actions in breast cancer. It is suggested that the tumor suppressive functions of TGF-ß involve Wnt5a-mediated antagonism of Wnt/ß-catenin signaling and limiting the stem cell population. Interactions between TGF-ß and Wnt5a in metastasis appear to be more complex, and may depend on specific cues from the microenvironment as well as activation of specific intracellular signaling pathways.     

Alternative Therapies for the Treatment of Chronic Prostatitis

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a prevalent disease for which there is no standardized therapy. Traditional treatments have included antibiotics, α-blockers, and anti-inflammatories, but those have not proven to be efficacious therapies through many clinical trials. Alternative therapies, such as phytotherapy, acupuncture, and pelvic floor physical therapy, have grown in popularity for the treatment of CP/CPPS. As clinicians continue to explore these alternative therapies, there is an accumulation of strong evidence demonstrating the success of these alternative therapies.     

Predictable Factors for Lymph Node Metastasis in Early Gastric Cancer—Analysis of Single Institutional Experience

Introduction  

Prediction of lymph node metastasis in early gastric cancer (EGC) is very important to decide treatment strategies preoperatively. The aim of this study was to evaluate factors that predict the presence of lymph node metastasis and to indentify the differences between mucosal and submucosal gastric cancers.     

Pulmonary valve preservation in Tetralogy of Fallot with a mildly hypoplastic annulus-should we do it?

Background  

The decision to preserve the pulmonary valve during intracardiac repair of Tetralogy of Fallot [TOF] is traditionally based on the intra-operative measurement of pulmonary annulus by a Hegar dilator as per Rowlatt’s table. We sought to evaluate if there can be flexibility in not using a transannular patch repair in Indian population with mildly hypoplastic pulmonary annulus.     

Adenocarcinoma in an intrapancreatic accessory spleen: Report of a case

We report a case of adenocarcinoma in an intrapancreatic accessory spleen (IPAS). A 78-year-old woman presented with abdominal discomfort, and investigations revealed an elevated serum carbohydrate antigen 19-9 level, to 161.8 U/ml (normal, <37 U/ml). Ultrasonography showed a heterogeneous echogenic tumor with a vascular hilum. Computed tomography showed a heterogeneously enhanced tumor, 8 cm in diameter, adjacent to the pancreatic body, accompanying a feeding artery arising from the splenic artery, and a drainage vein flowing into the splenic vein. We performed a distal pancreaticosplenectomy. The tumor was surrounded by a fibrous capsule and was in contact with the pancreatic body. Histological examinations revealed invasive growth of adenocarcinoma in a structure identical to the spleen. The results of both radiological and histological examinations suggested that the tumor originated from an intrapancreatic accessory spleen. Extensive examinations revealed no other malignancy, based on which we concluded that the adenocarcinoma was primary. Surgical intervention is strongly recommended when a malignancy in an IPAS cannot be ruled out.     

Bone Mineral Density in Young Women on Methadone Substitution

Little is known about bone mineral density (BMD) in patients with heroin addiction and subsequent methadone substitution. The goal of this study was to compare bone mass density of young HIV-negative women on long-term methadone treatment to a local group of young healthy women. Eleven women (aged 20–29) with previous heroin dependence and current methadone substitution (20–140 mg, median 60, daily) for 1.5–9 (median 3) years were compared to 30 healthy women (aged 20–28). Participants were examined with dual-energy X-ray absorptiometry of the lumbar spine (L2–L4), of the total proximal hip area, and of the femoral neck. Patients and controls had neither current nor lifetime underweight condition, had comparable ages at menarche, and did not differ significantly in current body mass index (21.9 ± 4.0, respectively, 20.5 ± 1.5 kg/m²) in spite of a largely unhealthy lifestyle (cigarette, alcohol, and cocaine consumption in patients). Patients’ total-hip parameters were marginally lower than those of controls (BMD P = 0.054, T score P = 0.049), whereas the femoral neck and lumbar spine parameters did not differ significantly between the two groups. Long-term methadone substitution in HIV-negative women seems to slightly affect bone mass density.
