INTRODUCTION: Congenital Zika Syndrome (CZS) has been associated with microcephaly and other central nervous system abnormalities including areas that have been implicated in the control of the lower urinary tract. As such, this descriptive case series has aimed to investigate whether CZS is linked with neurogenic bladder. Identifying such an association is paramount in the effort to recognize CZS complications that have putative treatment options that could mitigate the impact of CZS in infected children...

PURPOSE: To evaluate the correlation between the presence of bladder debris on ultrasound and urinalysis results in the emergency department setting. METHODS: Adult patients presenting to the emergency department with an ultrasound of the bladder and a urinalysis performed within 24 h of the ultrasound were included in this retrospective study. Two radiologists in consensus evaluated for the presence or absence of debris within the bladder. Urinalysis results were recorded including continuous variables (specific gravity and pH) and categorical variables (presence of occult blood, bilirubin, ketones, glucose, protein, urobilinogen, nitrite, leukocyte esterase, white blood cells, and red blood cells)...

BACKGROUND: Trigger finger is a common clinical disorder, characterised by pain and catching as the patient flexes and extends digits because of disproportion between the diameter of flexor tendons and the A1 pulley. The treatment approach may include non-surgical or surgical treatments. Currently there is no consensus about the best surgical treatment approach (open, percutaneous or endoscopic approaches). OBJECTIVES: To evaluate the effectiveness and safety of different methods of surgical treatment for trigger finger (open, percutaneous or endoscopic approaches) in adults at any stage of the disease...

BACKGROUND: Both mesh and suture repair are used for the treatment of umbilical hernias, but for smaller umbilical hernias (diameter 1-4 cm) there is little evidence whether mesh repair would be beneficial. In this study we aimed to investigate whether use of a mesh was better in reducing recurrence compared with suture repair for smaller umbilical hernias. METHODS: We did a randomised, double-blind, controlled multicentre trial in 12 hospitals (nine in the Netherlands, two in Germany, and one in Italy)...

The relation between hepatitis B virus (HBV) infection and fatty liver has been addressed by several observational studies, but their results remain controversial. To date, no study has precisely investigated the association of current and past HBV infection with the risk of nonalcoholic fatty liver disease (NAFLD) in the Chinese population. Therefore, we conducted a hospital-based case-control study in southwestern China to clarify this issue. A total of 631 newly ultrasound-diagnosed NAFLD cases and 2357 controls were selected from 123243 consecutive patients admitted to a tertiary-care hospital between January 2015 and December 2016...

OBJECTIVE CSF shunt infection requires both surgical and antibiotic treatment. Surgical treatment includes either total shunt removal with external ventricular drain (EVD) placement followed by new shunt insertion, or distal shunt externalization followed by new shunt insertion once the CSF is sterile. Antibiotic treatment includes the administration of intravenous antibiotics. The Hydrocephalus Clinical Research Network (HCRN) registry provides a unique opportunity to understand reinfection following treatment for CSF shunt infection...

The treatment of cancer using nanomedicines is limited by the poor penetration of these potentially powerful agents into and throughout solid tumors. Externally controlled mechanical stimuli, such as the generation of cavitation-induced microstreaming using ultrasound (US), can provide a means of improving nanomedicine delivery. Notably, it has been demonstrated that by focusing, monitoring and controlling the US exposure, delivery can be achieved without damage to surrounding tissue or vasculature. However, there is a risk that such stimuli may disrupt the structure and thereby diminish the activity of the delivered drugs, especially complex antibody and viral-based nanomedicines...

Viral hepatitis infection is a major global issue and a leading cause of liver disease and associated deaths. Over time, patients infected with hepatitis B (HBV) or C virus (HCV) develop cirrhosis and, eventually, hepatocellular carcinoma (HCC). For this reason, they need to be constantly monitored. Current Asian guidelines recommend the determination of serum alpha-fetoprotein (AFP) together with liver ultrasounds every six months to detect HCC nodules. However, both methods have several limitations, and other biomarkers have been studied for monitoring cirrhosis, including SCCA-IgM, an immune-complex formed by Squamous Cell Carcinoma Antigen and IgM...

The genus Onchocerca encompasses parasitic nematodes including Onchocerca volvulus, causative agent of river blindness in humans, and the zoonotic Onchocerca lupi infecting dogs and cats. In dogs, O. lupi adult worms cause ocular lesions of various degrees while humans may bear the brunt of zoonotic onchocercosis with patients requiring neurosurgical intervention because of central nervous system localization of nematodes. Though the zoonotic potential of O. lupi has been well recognized from human cases in Europe, the United States and the Middle East, a proper therapy for curing this parasitic infection in dogs is lacking...

BACKGROUND: Ascaris lumbricoides is one of the most common intestinal infections in developing countries, including Kosovo. In contrast to migration to the bile duct, migration of the worm to the gallbladder, due to the narrow and tortuous nature of the cystic duct, is rare. When it does occur, it incites acalculous cholecystitis. CASE PRESENTATIONS: This case series describes a 16-month-old Albanian girl, a 22-month-old Albanian girl, a 4-year-old Albanian girl, and a 10-year-old Albanian boy...

Splenic cysts are a rare entity in the Western population and are either true cysts (primary, 25%) or pseudocysts (secondary, 75%) complicating trauma, haemorrhage or infarction. Congenital or simple splenic cysts are the commonest primary cysts and surgery is recommended for cysts larger than 5 cm as these are prone to infection, bleeding or rupture and for symptomatic or complicated cysts. Splenic preservation techniques using the laparoscopic approach are the most prevalent. We present a case of a giant painful simple splenic cyst treated with laparoscopic de-capsulation with application of a new technique for achieving vascular control, whereby control of the splenic pedicle was achieved using a Nylon tape...

HIV-infected patients show high risk of fracture. The aims of our study were to determine the prevalence of vertebral fractures (VFs) and their associations with vitamin D in HIV patients. 100 patients with HIV infection and 100 healthy age- and sex-matched controls were studied. Bone mineral density was measured by quantitative ultrasound at the non-dominant heel. Serum osteocalcin and C-terminal telopeptide of collagen type 1 served as bone turnover markers. Bone ultrasound measurements were significantly lower in patients compared with controls (Stiffness Index (SI): 80...

A healthy woman volunteered to participate as "healthy control" in a study. An increased level of procalcitonin (PCT) was detected and remained elevated on follow-up measurements. As calcitonin levels were elevated as well, thyroid ultrasound was performed which revealed nodes in both thyroid lobes, one of them showing metabolic activity in positron emission tomography-computed tomography scan. To exclude a malignant thyroid cancer despite the negative findings in a fine needle aspiration the patient underwent thyroidectomy and a medullary thyroid carcinoma (MTC) was detected in the right lobe...

PURPOSE: The traditional technique of placing a peripheral intravenous (IV) catheter is successful in most cases on inpatient wards. However, when the traditional method fails, a central venous catheter may be placed to maintain IV access. These catheters are associated with risks including central line-associated bloodstream infection. METHODS: We evaluated the effectiveness and acceptability of an ultrasound-guided peripheral IV service to reduce the number of newly placed central venous catheters on an inpatient ward...

RATIONALE: Inflammatory myofibroblastic tumor (IMT) is an uncommon mesenchymal neoplasm, and its presence in a grafted liver is exceedingly rare. PATIENT CONCERNS: A 54-year-old woman was admitted to our hospital with a half-month history of intermittent melena. She had undergone deceased-donor liver transplantation (LT) for hepatitis B virus related liver cirrhosis without hepatocellular carcinoma 5 months previously. DIAGNOSIS: Laboratory examination showed impaired liver and renal functions and Epstein-Barr virus (EBV) infection, but tumor markers within normal ranges...

OBJECTIVE: Because of advances in technology and experience of the operator, endovascular aneurysm repair (EVAR) has supplanted open repair to treat abdominal aortic aneurysm (AAA). The low 30-day mortality and morbidity of EVAR make the endovascular approach particularly suitable for patients at high surgical risk. However, endoleak or endograft migration requiring secondary intervention or open surgical conversion is a limitation of EVAR. The Nellix system (Endologix, Inc, Irvine, Calif) has been designed to seal the entire AAA to overcome these limitations with EVAR...

BACKGROUND: Targeted temperature management (TTM) contributes to improved neurological outcome in adults who have been successfully resuscitated after cardiac arrest with shockable rhythm. Endovascular cooling catheters are widely used to induce and maintain targeted temperature in the ICU. The aim of the study was to compare the risk of complications with cooling catheters and standard central venous catheters. MATERIALS AND METHODS: In this prospective single-centre cohort study, we included all patients admitted to an intensive care unit for successfully resuscitated cardiac arrest that required endovascular TTM (Coolgard®, Zoll™ Medical corporation, MA, USA), between August 2012 and November 2014, inclusive...
