OBJECTIVE: Placental site trophoblastic tumor (PSTT) is rare and is characterized by a slow growth. The objective of this report is to present a case of PSTT associated with irregular vaginal spotting that occurred 1 year after normal vaginal delivery. CASE REPORT: This report provides interesting ultrasound, hysteroscopy, and histology findings of PSTT. It is difficult to make a clinical diagnosis of PSTT at an early stage. Without the use of immunohistochemical analysis, PSTT may evade histological detection...

: : Trauma-induced heterotopic ossification (HO) occurs after severe musculoskeletal injuries and burns, and presents a significant barrier to patient rehabilitation. Interestingly, the incidence of HO significantly increases with repeated operations and after resection of previous HO. Treatment of established heterotopic ossification is challenging because surgical excision is often incomplete, with evidence of persistent heterotopic bone. As a result, patients may continue to report the signs or symptoms of HO, including chronic pain, nonhealing wounds, and joint restriction...

BACKGROUND: Pediatric primary spinal tumors (PST) are fairly uncommon, with little available data regarding incidence and outcomes. MATERIALS AND METHODS: We conducted a retrospective review of the 22 consecutive patients less than 18 years old diagnosed with PST between March 1997 and May 2011 and treated at Chang Gung Children Hospital. All patients had undergone magnetic resonance imaging (MRI) for pre-operative evaluation and operations for PST. The extent of tumor removal was assessed by surgical report by the neurosurgeon or by post-operative MRI if available...

BACKGROUND: In 2009, NorthShore University HealthSystem adapted the World Health Organization Surgical Safety Checklist (SSC) at each of its 4 hospitals. Despite evidence that SSC reduces intraoperative mistakes and increase patient safety, compliance was found to be low with the paper form. In November 2013, NorthShore integrated the SSC into the electronic health record (EHR). The aim was to increase communication between operating room (OR) personnel and to encourage best practices during the natural workflow of surgeons, anesthesiologists, and nurses...

Errors are a part of life. With human errors accounting for approximately 50% of quality incidents and related problems within the pharmaceutical industry, the need to improve human performance in manufacturing operations is obvious. The purpose of this article is to describe error-proofing ways of structuring and writing knowledge documents, procedures, batch records, as well as practices for structuring, conducting, and documenting training to assure competence. These practices are recommended for adoption to shift the current 'training for compliance' paradigm to a 'training for competence' paradigm...

BACKGROUND: Understanding the dynamics of insecticide resistance in African malaria vectors is crucial for successful implementation of resistance management strategies in the continent. This study reports a high and multiple insecticide resistance in Anopheles funestus from southern Ghana which could compromise the Malaria Operational Plan in this country, if not tackled. Adult Anopheles mosquitoes were collected in Obuasi and Adawukwa, in southern Ghana. Plasmodium infection rates, susceptibility to the main insecticides used in public health and the molecular basis of insecticide resistance were established...

To describe the procedure, efficacy, and utility of single-incision laparoscopic-assisted stoma creation (SILStoma) for transverse colostomy. Using single-incision laparoscopic surgery, we developed a standardized technique for SILStoma. Twelve consecutive patients underwent SILStoma for transverse colostomy at Osaka Medical Center for Cancer and Cardiovascular Diseases from April 2013 to March 2016. A single, intended stoma site was created with a 2.5-3.5 cm skin incision for primary access to the intra-abdominal space, and it functioned as the main port through which multi-trocars were placed...

The histone methyltransferase SET8, whose expression is regulated by miR-502 though the binding site in the 3' UTR of SET8, implicated in cancer development. Single nucleotide polymorphism (SNP) of rs16917496 located in the miR-502 and SET8 binding site was analyzed in esophageal squamous cell carcinoma (ESCC) patients, the SET8 C/C genotype was independently associated with longer post-operative survival by multivariate analysis (relative risk, 2.250; 95% CI, 1.041-4.857; p = 0.039). Moreover, the reduced SET8 expression mediated by SET8 C/C genotype was associated with longer ESCC survival...

Background The medial sural vessels have been used extensively as donor vessels in free tissue transfer; however, there is sparse literature detailing their use as recipient vessels. The few existing reports involve small numbers of patients and describe operative approaches that are unnecessarily cumbersome. We explored our experience in free tissue transfer to the medial sural vessels and share a simplified operative approach to this recipient site. Methods A retrospective review was performed of all patients who underwent free tissue transfers to the medial sural vessels between December 2012 and December 2015 at a single institution...

In the presence of a diarylborinic acid catalyst, glycosyl methanesulfonates engage in regio- and stereoselective couplings with partially protected pyranoside and furanoside acceptors. The methanesulfonate donors are prepared in situ from glycosyl hemiacetals, and are coupled under mild, operationally simple conditions (amine base, organoboron catalyst, room temperature). The borinic acid catalyst not only influences site-selectivity via activation of 1,2- or 1,3-diol motifs, but also has a pronounced effect on the stereochemical outcome: 1,2-trans-linked disaccharides are obtained selectively in the absence of neighboring group participation...

BACKGROUND: Repeated surgery can be a measure of failure of the primary surgery. Future reoperations might be avoided if the cause is recognized and procedures or devices modified accordingly. Reoperations result in costs to both patient and the health care system. This paper proposes a new classification system for reoperations in end-stage ankle arthritis, and analyzes reoperation rates for ankle joint replacement and arthrodesis surgeries from a multicenter database. METHODS: A total of 213 ankle arthrodeses and 474 total ankle replacements were prospectively followed from 2002 to 2010...
