An 82-year-old woman visited the hospital with the chief complaint of dyspnea on light exertion. Computed tomography (CT) showed a coronary artery aneurysm and coronary arteriovenous fistulas. The pulmouary flow/systemic flow (Qp/Qs) ratio was 1.4, and the left-to-right shunt rate was 31%.Two anomalous vessels were identified. One arose from the right coronary artery, formed an aneurysm, and drained into the coronary sinus, while the other originated from the distal circumflex branch and drained directly into the coronary sinus...

BACKGROUND: In patients with non-expandable lung, removal of pleural fluid can result in excessively negative pleural pressure, which is associated with chest discomfort, pneumothorax, and re-expansion pulmonary oedema. Pleural manometry is widely used to safeguard against pressure-related complications during thoracentesis despite little evidence to support the approach. We investigated whether monitoring of pleural pressure with manometry during thoracentesis could protect against complications compared with assessment of symptoms alone...

An environmentally friendly method of etching a stainless steel plunger wire, to replace the conventional hydrofluoric acid approach, was developed for plunger-in-needle liquid phase-microextraction (PIN-LPME). The one-step etching procedure was performed by immersing the plunger wire in a ferric chloride-hydrochloric acid (FeCl3 -HCl) solution. The etched wire was then used for LPME as the organic solvent holder. After solvent coating, the wire was directly exposed to a water sample for extraction of polycyclic aromatic hydrocarbons (PAHs), which were then subjected to thermal desorption in the injector of a gas chromatograph for gas chromatography-mass spectrometric (GC-MS) analysis...

BACKGROUND Auricular hematomas are well-known among wrestlers and other contact sports participants, but spontaneous auricular hematomas are rare. The differential diagnosis for acute spontaneous auricular swelling is limited. In addition to infectious causes, antecedent trauma, and bleeding complications, angioedema should also be considered. Although rare, acute non-traumatic auricular hematomas need urgent surgical intervention if they are large. CASE REPORT A 37-year-old male presented to the Emergency Department (ED) with the complaint of acute pain and swelling to his left ear 30 minutes prior to arrival...

Importance: Resistance of gram-negative bacilli to carbapenems is rapidly emerging worldwide. In 2016, the World Health Organization defined the hospital-built environment as a core component of infection prevention and control programs. The hospital-built environment has recently been reported as a source for outbreaks and sporadic transmission events of carbapenemase-producing gram-negative bacilli from the environment to patients. Objective: To assess risk after the identification of an unexpected, severe, and lethal hospital-acquired infection caused by carbapenemase-producing Pseudomonas aeruginosa in a carbapenemase-low endemic setting...

Introduction: The study of the Sentinel Lymph Node (SLN) in Melanoma is a procedure that aims the identification of the first node to which the affected cutaneous sector drains in order to avoid unnecessary lymphadenectomies. The present study documents the frequency of identification of SLN; the relationship between positive SLN (PSLN) and recurrence, between the Breslow index (BI) and PSLN, and between BI and disease recurrence. Method: We analyzed the records of 148 patients with melanoma stages I and II undergoing lymphatic mapping and GC biopsy from 1999 to 2017 in a third level institution in Córdoba, Argentina...

Background: Acute pancreatitis represents one of the most frequent digestive pathologies worldwide, which can be complicated as an infected necrotizing acute pancreatitis, that may require treatment with necrosectomy and open abdomen with the risk that this leads to the appearance of intestinal fistula and giant incisional hernias difficult to manage. Clinical case: A 35-year-old woman underwent laparoscopic cholecystectomy for acute cholecystitis, which was re-admitted due to jaundice and abdominal pain 3 days after her hospital discharge...

We demonstrated that hand washing resulted in frequent dispersal of gram-negative bacilli from colonized sink drains in hospitals to cover gowns and hands. A plastic drain cover reduced but did not eliminate the risk for contamination. This mechanism of dispersal could result in contamination of healthcare personnel and patients.

Background and Aims: GI tract perforations and anastomotic dehiscence are increasingly effectively being repaired endoscopically; however, well-known and long-held surgical principles must still be honored. One important principle is that significant extraluminal contamination must be washed out, debrided, and drained in conjunction with repair of the defect if the wound is to effectively heal and resolve. Here we describe the use of endoscopic washout and debridement of extraluminal contamination at the time of luminal defect closure in a 7-patient series at our institution, with video demonstration of 2 patients in the series...

Introduction: Despite the advantages and expanded indications of video-assisted thoracoscopic surgery, the open surgical approach is commonly preferred for the surgical treatment of rib lesions. Such an approach could lead to disadvantageous results such as increased postoperative pain and prolonged hospital stay. Despite all these handicaps, thoracoscopic resection of isolated rib resection has been reported in a small number of publications. Aim: To compare the clinical outcomes of patients with isolated benign rib pathologies treated with either minimally invasive or open surgery...

Chronic subdural hematoma (CSDH) is one of the most common neurosurgical conditions. Despite ongoing efforts, recurrence and reoperation rates after surgical treatment remain high. We synthesize scientific evidence on the treatment of CSDH with biophysical principles and then propose a simple and effective surgical technique aiming to reduce the recurrence rate. Under local anesthesia, one burr hole is placed in the area above the maximum hematoma thickness. One drain is inserted into the dorsal direction to the deepest point of the hematoma cavity, and a second drain is inserted frontally into the highest point...

InP based HEMTs are of great importance, due to their enormous potential in a high-speed modern microwave circuit, power amplifier, and low noise amplifier applications. Therefore, an accurate non-linear equivalent circuit model of HEMTs is very important for an accurate circuit design. This paper presents improved characterization and accurate modelling of drain current derivatives of InP based HEMTs devices. The proposed model is simple, easy to extract, and suitable for implementation in simulation tools...

Stormwater is increasingly being valued as a freshwater resource in arid regions and can provide opportunities for beneficial reuse via aquifer recharge if adequate pollutant removal can be achieved. We envision a multi-unit operation approach to capture, treat, and recharge (CTR) stormwater using low energy, cost-effective technologies appropriate for larger magnitude, less frequent events. Herein, we tested nutrient, metal, and trace organic contaminant removal of a pilot-scale CTR system in the laboratory using biochar-amended woodchip bioreactors following eight months of aging under field conditions with exposure to real stormwater...

Previous studies showed that Echinococcus granulosus infection reduces allergic airway inflammation in experimentally infected hosts and the cystic fluid of E. granulosus is known to activate regulatory T (CD4+ CD25+ Foxp3+ T, Treg) cells. To evaluate the effects of cystic fluid of E. granulosus on allergic airway inflammation, we investigated the regulation of the inflammatory reaction by cystic fluid using an allergic airway inflammation animal model. Cystic fluid was administered to C57BL/6 mice seven times every other day, after which allergic airway inflammation was induced using ovalbumin and aluminum...

Imperfections in the crystal lattice, such as defects, grain boundaries, or dislocations, can significantly affect the optical and electrical transport properties of materials. In this study, we report the effect of mid-gap trap states on photocurrent in 10 atomic layered 2H-MoTe2. Our study reveals that the photocurrent is very sensitive to the number of active traps, which can be controlled by Vgs. By fitting the measured transient drain current, our estimation shows that the trap state density is approximately 5 × 1011 cm-2...

Hepatic angiomyolipoma (AML) is a rare stromal tumor composed of variable admixtures of thick-walled vessels, smooth muscles and adipose tissue. One of the specific radiological findings of hepatic AML is an early drainage vein noted via enhanced computed tomography (CT). We report a case of hepatic AML showing early drainage veins into both the hepatic and portal vein. The case involved a 46-year-old woman who was referred to our hospital because of a giant hepatic tumor. CT revealed well-enhanced 14 cm and 1 cm tumors in the left and right lobes, respectively...
