BACKGROUND: Renal and bladder ultrasound (RBUS) is recommended in evaluation of children after an initial, febrile urinary tract infection. Although it is not uncommon to observe debris within the bladder lumen on sonography, the significance of this finding is uncertain. Debris may be interpreted as an indication of ongoing infection, but there have been no studies to date investigating the association of bladder debris with a positive culture. OBJECTIVE: The aim of this study was to evaluate the association of bladder debris noted at the time of RBUS with positive urine culture results obtained from a catheterized specimen, among patients undergoing RBUS and voiding cystourethrogram (VCUG) on the same day...

Hepatocellular carcinoma (HCC) is a common malignant tumor worldwide, with high morbidity and mortality. Chronic infection with hepatitis B virus (HBV) is a major risk factor for the development of hepatocellular carcinoma and the majority (~80%) of hepatocellular carcinoma patients in China exhibit co-morbidity with HBV-associated liver cirrhosis. The goal of reliable early diagnostic and prognostic techniques for HBV-associated HCC remains unrealized. The aim of the present study was to explore the efficacy of serum high-sensitivity C-reactive protein (hs-CRP) tests in the early diagnosis of HCC in patients with HBV-associated liver cirrhosis...

Traditional wound care methods include wound infection control, adequate nutritional supplements, education of changing position every 2-3 h to avoid tissue hypoxia, vacuum assistant closure, debridement, skin graft, and tissue flap. Electric current stimulation, ultrasound, laser, and hydrotherapy have emerged as adjuvant therapies. However, most, if not all, of these therapies are expensive, and the treatment results are variable. The development of the active methods to improve wound healing is mandatory...

OBJECTIVE: Dirofilariasis is a parasitic infection caused by filarial nematodes belonging to the genus Dirofilaria. Human dirofilariasis due to Dirofilaria repens has been widely reported from European countries. Sri Lanka is the most affected country in Asia with an infection rate of almost 60% in dog population. However, human infection of D. repens remains undiagnosed and many of the cases are not scientifically documented. Therefore, the objective of the present investigation is to document the presence of dirofilariasis infections in humans...

Ramesh Babu, Sujit Chowdhary
The primary goal in the management of a child with urinary tract infection (UTI) is to prevent recurrence of UTI and acquired renal damage. Approximately 15% of children develop renal scarring after a first episode of febrile UTI. Vesico-ureteric reflux (VUR) is diagnosed in 30-40% of children imaged after first febrile UTI. The 'top-down' approach involving ultrasound and dimercaptosuccinic acid scan (DMSA) first after an appropriate interval following UTI, can help in avoiding voiding cystourethrogram (VCUG), an invasive test with higher radiation exposure...

BACKGROUND: Pleural empyema is a well-known complication of pneumonia. If treatment is delayed, empyema may increase morbidity and mortality in affected patients. Therefore, the identification of empyema biomarkers in parapneumonic pleural effusion is desirable. Previous research has suggested complement activation products as candidate empyema markers. OBJECTIVE: To compare the levels of complement activation products C3a, C5a, and C5b9 in pleural effusion induced by Staphylococcus aureus (SA), Streptococcus pneumoniae (SP), or turpentine (control)...

BACKGROUND: Ultrasound has been applied in fruit pre-washing processes. However, it is not sufficient to protect fruit from pathogenic infection throughout the entire storage period, and sometimes ultrasound causes tissue damage. The goal of this study was to investigate the effects of calcium chloride (10 g L(-1) ) and ultrasound (350 W at 40 kHz), separately and in combination, on fruit quality, antioxidant status, tissue Ca(2+) content and distribution along with cell wall metabolism at 20 °C for six days...

Preterm birth (PTB) is one of the major health-care challenges of our time. Being born too early is associated with major risks to the child with potential for serious consequences in terms of life-long disability and health-care costs. Discovering how to prevent PTB needs to be one of our greatest priorities. Recent advances have provided hope that a percentage of cases known to be related to risk factors may be amenable to prevention; but the majority of cases remain of unknown cause, and there is little chance of prevention...

Introduction: Biofilms are recognized as a significant deterrent to wound healing and to the management of exposed or infected surgical implants. Biofilms can be disrupted by a variety of enzymatic and mechanical interventions. This experiment was designed to determine whether direct-contact low-frequency ultrasound has the ability to clear biofilms and what then happens to the released bacteria. Methods:Staphylococcus epidermidis biofilm was grown on the surfaces of metallic discs composed of titanium and stainless steel, comparable with the alloys used in surgical implants...

When acute mastoiditis occurs in cochlear implant recipients, it can progress to subsequent retroauricular abscess due to the absence of the external mastoid cortex resulting from mastoidectomy performed for cochlear implantation. The management goal is to control infection while preserving the implanted device. A 2-year-old boy with cochlear implants developed acute mastoiditis and a subsequent retroauricular abscess. The patient underwent a surgical intervention based on the diagnosis made utilizing gray-scale and power Doppler sonography...

The Centers for Disease Control and Prevention guidelines for the prevention of catheter-related bloodstream infections suggest using "a subclavian site, rather than an internal jugular or a femoral site, in adult patients." This recommendation is based on evidence of lower rates of thrombosis and catheter-related bloodstream infections in patients with subclavian central venous catheters (CVCs) compared to femoral or internal jugular sites. However, preference toward a subclavian approach to CVC insertion is hindered by increased risk of mechanical complications, especially pneumothorax, when compared to other sites...

PURPOSE: Trigger finger is a common condition with a lifetime prevalence of 2%. Corticosteroid injection is a treatment often considered as a first-line intervention with reported cure rates between 60% and 90% in observational cohorts. Nevertheless, open surgery remains the most effective treatment with reported cure rates near 100%. Head-to-head trials on these treatments are limited. We investigated the efficacy of open surgery compared with ultrasound-guided corticosteroid injections...

BACKGROUND: Currently, both the step-up approach, combining percutaneous drainage (PD) and video-assisted retroperitoneal debridement (VARD), and endoscopic transgastric necrosectomy (ETN) are mini-invasive techniques for infected necrosis in severe acute pancreatitis. A combination of these approaches could maximize the management of necrotizing pancreatitis, conjugating the benefits from both the experiences. However, reporting of this combined strategy is anecdotal. This is the first reported case of severe necrotizing pancreatitis complicated by biliary fistula treated by a combination of ETN, PD, VARD, and endoscopic biliary stenting...
