BACKGROUND: Currently, different types of treatments for pathological scars are available, however, to date, there is no established method of measurement to objectively assess therapeutic outcome. Treatment success is usually evaluated clinically by the physician and patient. Non-invasive imaging techniques, such as HD-OCT (high-definition optical coherence tomography), may represent a valuable diagnostic tool to objectively measure therapeutic outcome. OBJECTIVES: To compare HD-OCT with ultrasound and subjective evaluation tools, such as questionnaires...

Equids can be infected by a range of skin-dwelling filarial nematodes, including four species of the genus Onchocerca. Current literature on equine onchocercosis is fragmentary and often limited to isolated case reports. The present study aimed to describe a clinical case of equine onchocercosis caused by Onchocerca boehmi (Supperer, 1953) (syn. Elaeophora boehmi) in an 8-year-old gelding Belgian show jumper from northern Italy. The horse was presented with a firm and painless mass on the proximal third of the right metacarpal region...

BACKGROUND: In patients with intrathoracic lymphadenopathy, differentiating tuberculosis from sarcoidosis is often difficult. We hypothesized that Xpert MTB/RIF assay, a semi-automated hemi-nested PCR would help in this regard. OBJECTIVE: To evaluate the performance of Xpert MTB/RIF in the differential diagnosis of tuberculosis and sarcoidosis. METHODS: This was a retrospective analysis of patients with intrathoracic lymphadenopathy who underwent endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration (TBNA), and were diagnosed as either tuberculosis or sarcoidosis...

The aim of this study was to identify skin properties that may be used to predict the development of a skin tear (ST) among elderly patients. A prospective cohort study was conducted among elderly patients aged 65 and older (N = 149) at a long-term medical facility in Japan over an 8-month period. Skin properties at baseline were measured on the forearm using a 20-MHz ultrasound scanner, which measured the thickness of the dermis layer and low-echogenic pixels, and skin blotting method, which evaluated the levels of collagen type IV, matrix metalloproteinase-2 and tumour necrosis factor-alpha...

Granular cell tumors (GCTs) are soft tissue neoplasms that originate from Schwann cells. They occur predominantly in the oral cavity, skin, and breast tissues. Gastrointestinal GCTs are very rare, accounting for only eight percent of all GCTs, most of which are located in the esophagus. Endoscopic ultrasound has been a breakthrough in diagnosing GCTs because it provides precise information on the depth of tumor invasion, thus narrowing the differential diagnosis of subepithelial lesions in the esophagus. However, the definitive diagnosis requires histological confirmation of the lesion...

BACKGROUND: Excess adiposity and adiposity-related inflammation are known risk factors for cardiovascular disease in adults; however, little is known regarding the determinants of adiposity-related inflammation at birth. OBJECTIVES: The aim of this study was to investigate the association between maternal pre-pregnancy BMI and newborn adiposity and inflammation. METHODS: Paired maternal (28-week gestation) and infant (umbilical cord) blood samples were collected from a population-derived birth cohort (Barwon Infant Study, n = 1074)...

INTRODUCTION: The development of cutaneous neoplasms at immunization sites following vaccination is uncommon, and only few have been reported in the literature worldwide. We report an unusual case of an ulcerated giant dermatofibroma that developed as a chronic nonhealing plaque in the immunization scar of a young boy after vaccination. CASE REPORT: A 13-month-old Chinese boy presented with an unusual skin reaction on the vaccination site at the right anterolateral thigh following a routine intramuscular injection of '5-in-1' (diphtheria, tetanus, pertussis, polio and Haemophilus influenzae B) vaccine at 4 months of age...

High-frequency 3-D ultrasound imaging is an informative tool for diagnosis, surgery planning and skin lesion examination. The purpose of this article was to describe a semi-automated segmentation tool providing easy access to the extent, shape and volume of a lesion. We propose an adaptive log-likelihood level-set segmentation procedure using non-parametric estimates of the intensity distribution. The algorithm has a single parameter to control the smoothness of the contour, and we describe how a fixed value yields satisfactory segmentation results with an average Dice coefficient of D = 0...

INTRODUCTION: Femoral nerve block (FNB) is considered as a major advance in anterior cruciate ligament (ACL) reconstruction as it reduces the need for parenteral opioids. However, the incidence of transient or even permanent neurological deficits due to the FNB is estimated at 1.94% after knee surgery. The primary objective of this study was to compare local infiltration analgesia (LIA) to FNB during ACL reconstruction procedures. The study hypothesis was that LIA was not less effective than FNB on early postoperative pain...

INTRODUCTION: Incisional biopsy may not always provide a correct classification of histologic subtypes of basal cell carcinoma (BCC). High-frequency ultrasound (HFUS) imaging of the skin is useful for the diagnosis and management of this tumor. OBJECTIVES: The main aim of this study was to compare the diagnostic value of HFUS compared with punch biopsy for the correct classification of histologic subtypes of primary BCC. We also analyzed the influence of tumor size and histologic subtype (single subtype vs...

Inspired by the application of ultrasonic cavitation based mechanical force (CMF) to open small channels in natural soft materials (skin or tissue), it is explored whether an artificial polymer network can be created, in which shape-changes can be induced by CMF. This concept comprises an interconnected macroporous rhodium-phosphine (Rh-P) coordination polymer network, in which a CMF can reversibly dissociate the Rh-P microphases. In this way, the ligand exchange of Rh-P coordination bonds in the polymer network is accelerated, resulting in a topological rearrangement of molecular switches...

INTRODUCTION: Introducer needle tip is not clearly visible during the real-time ultrasound (US)-guided central vein cannulation (CVC). Blind tip leads to mechanical complications. This study was designed to evaluate whether real-time US-guided CVC with a marked introducer needle is superior to the existing unmarked needle. METHODOLOGY: Sixty-two critically ill patients aged 18-60 years of either sex were included in the study. The patients were randomized into two groups based on whether a marked or unmarked introducer needle was used...

BACKGROUND: Endoscopic endonasal approaches (EEA) are an alternative for removing challenging nasopharyngeal or skull base lesions. In some cases, a nasoseptal flap (NSF) is not always available and such complex procedures may lead to carotid arteries exposition and/or dura mater (DM) wide opening. Meticulous carotid coverage and DM reconstruction are crucial for preventing early and delayed complications. METHOD: We propose a step-by-step description of the pedicled temporoparietal fascia flap (TPFF) technique, with a focus on its pitfalls, advantages and limits...

Penile augmentation has been reported in the literature by injecting various materials. This study reports our experience in management of penile augmentation complications associated with selfpenile injection of silicone liquid. After a careful ultrasound study, the penile skin was excised through a circumferential sub-coronal incision and dissected with the silicon mass. Histology was well-compatible with silicone granulomas. The patient was discharged after 24 hours. Ultrasonography has permitted preoperatively to determine if the plane between the indurated inflammatory tissue and the Buck's fascia was preserved for the complete surgical excision of affected tissue...

BACKGROUND: Regional epidural analgesia is considered the gold standard for pain treatment in labour but the epidural catheter placement may be a difficult procedure because of the difficulty in anatomical landmarks palpation. These difficulties increase in pregnant women. Pre-procedure neuroaxial ultrasound may facilitate the procedure. METHODS: Prospectic randomized controlled study conducted in the Labour Ward. We randomized two groups of women undergoing epidural analgesia: Group A (28 patients), with loss of resistance technique and Group B (30 patients) with US assisted procedure...
