BACKGROUND: The Adult Congenital Heart Association (ACHA) is dedicated to supporting patients with congenital heart disease. To guide patients to qualified providers and programs, it maintains a publicly accessible directory of dedicated adult congenital cardiac programs. We analyzed the directory in 2006 and 2015, aiming to evaluate the growth of the directory as a whole and to evaluate the growth of individual programs within the directory. We also hope this raises awareness of the growing opportunities that exist in adult congenital cardiology and cardiac surgery...

BACKGROUND: The reported malignancy rates of thyroid nodules that appear suspicious on ultrasound (US) but yield benign fine-needle aspiration (FNA) cytology results range from 13.6% to 56.6%. However, the malignancy risk of nodules that are discordant on US and core-needle biopsy (CNB) pathological findings has not been evaluated. This study evaluated the malignancy risk associated with thyroid nodules that are suspicious on US but yield benign CNB results. METHODS: Between July 2008 and November 2011, 1309 patients with 1313 thyroid nodules underwent US-guided CNB...

Prosthetic joint infection is a devastating complication of arthroplasty surgery that can lead to debilitating morbidity for the patient and significant expense for the healthcare system. With the continual rise of arthroplasty cases worldwide every year, the revision load for infection is becoming a greater financial burden on healthcare budgets. Prevention of infection has to be the key to reducing this burden. For treatment, it is critical for us to collect quality data that can guide future management strategies to minimise healthcare costs and morbidity / mortality for patients...

BACKGROUND: Port-site infection (PSI) is a prevailing, chronic, nagging, treatment refractory complication of laparoscopic surgery (LS). It neutralizes the advantages of minimally invasive surgery and increases morbidity, treatment cost of patient, leading to loss of confidence on operating surgeon. PSIs are preventable with appropriate preoperative, intraoperative, and postoperative measures. Atypical mycobacterium is most commonly associated with nonhealing postlaparoscopic wound infections, causing outbreaks or sporadic cases worldwide...

BACKGROUND: A better understanding of the blood supply of the femoral head is essential to guide therapeutic strategies for patients with femoral neck fractures. However, because of the limitations of conventional techniques, the precise distribution and characteristics of intraosseous arteries of the femoral head are not well displayed. QUESTIONS/PURPOSES: To explore the characteristics and interconnections of the intraosseous vessel system between different areas of the femoral head and the possible blood supply compensatory mechanism after femoral neck fracture...

REVIEW
Darcy E Broughton, Kelle H Moley
The worldwide upward trend in obesity has been dramatic, now affecting more than 20% of American women of reproductive age. Obesity is associated with many adverse maternal and fetal effects prenatally, but it also exerts a negative influence on female fertility. Obese women are more likely to have ovulatory dysfunction due to dysregulation of the hypothalamic-pituitary-ovarian axis. Women with polycystic ovarian syndrome who are also obese demonstrate a more severe metabolic and reproductive phenotype. Obese women have reduced fecundity even when eumenorrheic and demonstrate poorer outcomes with the use of in vitro fertilization...

Correct localization of the needle is of vital importance to guarantee successful puncture. The complexity of real US data increases the difficulties. A multi-scale random sample consensus (MS-RANSAC) algorithm is proposed in this paper to locate the needle in complicated 3D US data. The algorithm uses the radius difference between needle and other tubular human tissues to extract the correct needle location. The performance of classic RANSAC and MS-RANSAC are compared using three different datasets. Results show that MS-RANSAC can locate needle correctly in complicated condition where classic RANSAC cannot...

According to the US Center for Disease Control, cancer deaths are the second most common cause of mortality in both adults and children. Definitive treatment of solid tumors involves surgical resection with or without systemic chemotherapy and radiation. The advent of local drug delivery presents a unique treatment modality that can offer substantial benefits in cancer management. Local drug delivery offers targeted drug delivery to cancer tissues while minimizing side effects of the medications. Three main phases in solid tumor management exist for the treating physician: initial diagnosis with tissue biopsy, surgical resection with or without chemotherapy, and management of metastatic disease...

BACKGROUND: The low rate of progression associated with the potential complications of thyroidectomy makes active surveillance an increasingly recommended management in low-risk papillary microcarcinomas of the thyroid (PMT). The objective of this study was to report the results of fine needle aspiration (FNA) of nodules ≤ 1 cm with highly suspicious appearance on ultrasonography (US) in patients who are potential candidates for active surveillance. METHODS: We revised thyroid nodules ≤ 1 cm with highly suspicious appearance on US in patients without known distant metastases, suspicion of extrathyroid extension, or suspicious lymph nodes on US...

Importance: In 2014, the US Department of Health and Human Services decided that its 1981 exclusion of transsexual surgical treatments from Medicare coverage was based on outdated, incomplete, and biased science and did not reflect current evidence or standards of care, and the exclusion was therefore lifted. As a direct result of this decision, surgeons nationwide are seeing an increase in consultations for surgical therapy to help transgender and gender-nonconforming individuals. Although some clinicians may have the technical training for such surgical procedures, in many cases, they may not have a full understanding of the complex and comprehensive care required to provide optimal health care for transgender individuals...

Virtual surgical planning technology in head and neck surgery is witnessing strong growth. In the literature, the validity of the method from the point of view of accuracy and clinical utility has been widely documented, especially for bone modelling. To date, however, with its increased use in head and neck oncology, and consequently the increased need for bone and soft tissue reconstruction, is important to carry out the virtual programme considering not only bone reconstruction but also all aspects related to the reconstruction of soft tissue using composite flaps...

Renal cell carcinoma accounts for 3% of adult solid malignant tumours. Approximately 25% of the patients present with metastatic disease at presentation. In the era of immunotherapy (interferon alpha-2b and interleukin-2), studies showed significant survival benefit with cytoreductive nephrectomy (CRN) followed by interferon alpha-2b than interferon alpha 2-b alone. Introduction of targeted therapies (vascular endothelial growth factor receptor-tyrosine kinase inhibitors, mammalian target of rapamycin inhibitors) in 2005 generated a great interest in the management of metastatic renal cell carcinoma (mRCC) as these drugs exhibited tumour shrinkage in the primary tumour as well as in the metastatic site/s...

In recent years, brachial plexus anesthesia techniques for upper limb surgery have been used more and more commonly on children; however, the patient is typically under deep sedation or general anesthesia. For eligible, cooperative children, surgery can also be performed using regional blocks while the patient is awake. We present 5 cases in which Ultrasound (US)-guided infraclavicular brachial plexus blocks (ICB) were used on children for hand or forearm surgery. Surgical anesthesia was achieved in all patients and surgery was completed uneventfully using brachial plexus anesthesia, without need for deep sedation...

Image-guided spinal surgery is becoming increasingly popular because it allows surgeons to achieve minimal invasiveness and maximum precision in the performed procedures. We present our initial experience with two cases operated on using O-arm-based spinal navigation at the Clinic of Neurosurgery in St George University Hospital, Plovdiv, Bulgaria. In the first case, we performed removal of extradural spinal tumor of the sixth thoracic vertebra and O-arm-navigated pedicle screw fixation. In the second case, we performed O-arm-navigated corpectomy of the fifth cervical vertebra and anterior spinal reconstruction and fusion with titanium expandable mesh and cervical plate in connection with degenerative narrowing of the cervical spinal canal that lead to clinically manifested myelopathy...
