A 25-year-old male presented with difficulty in walking, loss of vision, and seizures. A clinical possibility of craniospinal meningeal pathology was considered. On computed tomography (CT) scan and magnetic resonance imaging, there was an enhancement of leptomeninges with few ring-enhancing lesions in both frontal lobes and right frontoparietal region. He was evaluated for low backache and occipital headache 2½ years earlier and was found to have communicating hydrocephalus on CT scan. He underwent ventriculoperitoneal shunt and was followed up with CT scans...

Nichole E Brinkman, G Shay Fout, Scott P Keely
Enteroviruses are RNA viruses that are responsible for both mild gastroenteritis and mild respiratory illnesses as well as debilitating diseases such as meningitis and myocarditis. The disease burden of enteroviruses in the United States is difficult to assess because most infections are not recorded. Since infected individuals shed enterovirus in feces and urine, surveillance of municipal wastewater can reveal the diversity of enteroviruses circulating in human populations. Therefore, monthly municipal wastewater samples were collected for 1 year and enteroviruses were quantified by reverse transcriptase quantitative PCR and identified by next-generation, high-throughput sequencing...

Qingchun Ge, Gary Lee Amy, Tai-Shung Chung
Forward osmosis (FO) has demonstrated its merits in hybrid FO seawater desalination. However, FO may have a potential for other applications if suitable draw solutes are available. In this study, a series of novel draw solutes based on oxalic acid (OA)-transitional metal complexes are presented. Influential factors of FO performance have been systematically investigated by varying the transitional metals, cations of the complex draw solutes as well as the experimental conditions. Compared to NaCl and other recently synthesized draw solutes, the OA complexes show superior FO performance in terms of high water fluxes up to 27...

Erin T Landis, Rita O Pichardo-Geisinger
Alopecia areata is a form of nonscarring hair loss which occurs in pediatric and adult patients, with presentation varying from round or ovoid patches of alopecia to alopecia totalis or universalis. While frustrating for patients, it can also be frustrating for clinicians to treat, as there is no definitive treatment. Dermatologists are very familiar with the use of methotrexate for psoriasis and other inflammatory skin diseases, and this medication is generally well tolerated in children. This study present a case series reviewing the efficacy of methotrexate in our pediatric patients with alopecia areata, making use of a retrospective chart review design from 2011-2016...

Hem-o-lok clips have been widely used in laparoscopic or robot-assisted surgery. We report a case of an incidentally discovered Hem-o-lok migration into the bladder after laparoscopic radical prostatectomy. The patient was a 75-year-old man with localized prostate cancer who underwent laparoscopic radical prostatectomy in July 2009. At 3 postoperative years, follow-up ultrasonography revealed a small round mass in the bladder. No lower urinary tract symptoms were reported, and urinalysis results had never indicated hematuria or pyuria...

We show experimental evidence of the acoustically-assisted micromanipulation of small objects like solid particles or blood cells, combining rotation and translation, using high frequency surface acoustic waves. This was obtained from the leakage in a microfluidic channel of two standing waves arranged perpendicularly in a LiNbO3 piezoelectric substrate working at 36.3 MHz. By controlling the phase lag between the emitters, we could, in addition to translation, generate a swirling motion of the emitting surface which, in turn, led to the rapid rotation of spherical polystyrene Janus beads suspended in the channel and of human red and white blood cells up to several rounds per second...

S. dandelenae sp. nov. is described from the west coast of South Africa and occurs at depths of 80-500 m among unconsolidated sediments. Specimens can reach 40 cm in length and in some areas off South Africa, up to 18 tons/km2 can be collected in a single demersal trawl. Morphologically, the sponge is straw yellow, massive with rounded lobes and has a velvety surface: it is characterized by subradiate, irregular reticulation of bundles of tylostyles and tylostrongyles. Specimens of S. dandelenae sp. nov. have three size classes of tylostyles with the largest tylostyle lengths being 516 μm (441-614 μm), medium tylostyle lengths being 352 μm (307-422 μm) and the shortest tylostyle lengths being 215 μm (153-288 μm)...

A pathobiological study was conducted using Vibrio parahaemolyticus (VP) strain isolated from vibriosis affected shrimp (Penaeus vannamei) farms in Kancheepuram and Thiruvallur districts of Tamil Nadu during August 2014 to February 2015. The isolate was identified based on the morphological, physiological, biochemical and molecular characters. LD50 value with intramuscular injection was determined as 2.6 × 10(4) cfu/shrimp and sequential pathology was studied giving 6.1 × 10(3) cfu/shrimp (LD25). Total plate count (TPC) and total Vibrio count (TVC) in water, pond sediment, haemolymph, muscle, HP and gut were found significantly (P < 0...

The Republic of Ireland has a national eradication programme for bovine viral diarrhoea virus (BVDv) based on tissue-tag testing of calves to identify persistently infected animals (PIs). It has been proposed that serological testing of a sample of home-bred young stock would be a more cost effective surveillance mechanism than continued tissue-tag testing in herds which have previously been found to be BVD-free. These animals would have to be at least 6 months of age to avoid interference from maternal antibodies in test results...

The source and significance of residual low-level viremia (LLV) during combinational antiretroviral therapy (cART) remain a matter of controversy. It is unclear whether residual viremia depends on ongoing release of HIV from the latent reservoir or if viral replication contributes to LLV. We examined the relationship between adherence and LLV. Adherence was estimated by pharmacy refill and dichotomized as ≥95% or <95%. Plasma HIV-RNA was determined, with an ultrasensitive test having a limit of detection of 3 copies/mL at least 2 times over the follow-up period...

We report the result of treatment of 69 complex clasped thumbs in 39 patients with distal arthrogryposis. The mean age at surgery was 30 months. Surgical reconstruction included skin augmentation of the first web using modified dorsal rotation advancement flap (Abdel-Ghani flap), a la Carte release of tight structures of the first web, and chondrodesis of the thumb metacarpophalangeal joint. The mean follow-up was 4 years. We prefer chondrodesis because of the presence of global instability, abnormal joint structure, abnormal articular surfaces, and inefficient muscles for transfer...

This study describes which clinical ethics approaches are available to support healthcare personnel in clinical practice in terms of their construction, functions and goals. Healthcare personnel frequently face ethically difficult situations in the course of their work and these issues cover a wide range of areas from prenatal care to end-of-life care. Although various forms of clinical ethics support have been developed, to our knowledge there is a lack of review studies describing which ethics support approaches are available, how they are constructed and their goals in supporting healthcare personnel in clinical practice...

BACKGROUND: Upper gastrointestinal subepithelial tumors (SETs) may harbor potential malignancy. Although it is well recognized that large SETs should be resected, the treatment strategy remains controversial. Compared to surgical resection, endoscopic resection has many advantages such as less invasive, shorter hospital stay, lower costs, and better quality of life. However, Endoscopic resection of large SETs in the cardia is challenging. The purpose of this study was to evaluate the safety and efficacy of endoscopic submucosal dissection (ESD) in the treatment of such SETs...

BACKGROUND: Accomplishing infection prevention and control (IPC) in health facilities in Sub-Saharan Africa is challenging. Owing to poor IPC, healthcare workers (HCWs) were frequently infected during Sierra Leone's Ebola epidemic. In late 2014, IPC was rapidly and nationally scaled up. We carried out workshops in sampled facilities to further improve adherence to IPC. We investigated HCW experiences and observed practice gaps, before and after the workshops. METHODS: We conducted an uncontrolled, before and after, mixed-methods study in eight health facilities in Bo and Kenema Districts during December 2014 and January 2015...
