Although pyogenic liver abscess (PPLA) fatalities are decreasing owing to early diagnosis and effective treatments, PPLA-associated complications still exist. The purpose of this study was analyze the characteristic features initial presentations final outcomes PPLA caused by different pathogens.This retrospective collected analyzed information regarding in patients diagnosed with at admitted Changhua Christian Hospital from January 1 December 31, 2010.During period, we records a total 134...

Obstructive sleep apnea/hypopnea syndrome (OSAHS) is characterized by repeated airflow partial reduction or complete cessation due to upper airway collapse during sleep. OSAHS can induce frequent awake and intermittent hypoxia that associated with hypertension cardiovascular events. Full-channel Polysomnography (PSG) the gold standard for diagnosing OSAHS; however, this PSG evaluation process unsuitable home screening. To solve problem, a measuring module integrating abdominal thoracic...

It is well known that elementary particles in the real <a:math xmlns:a="http://www.w3.org/1998/Math/MathML"><a:mrow><a:mn>3</a:mn><a:mo>+</a:mo><a:mn>1</a:mn></a:mrow></a:math>-dimensional world are either bosons or fermions, without exception, and not both. Here, we show a quantized current-biased Josephson junction (CBJJ), as an artificial macroscopic “particle,” can serve boson fermion combination, depending on amplitude of biased dc current. By using high vacuum two-angle electron beam...

Laparoscopic greater curvature plication (LGCP) is a new bariatric procedure that similar to laparoscopic sleeve gastrectomy (LSG) in it uses restrictive mechanism. Comparative studies between LGCP and LSG were still limited. The aim of this study was compare the clinical outcomes two procedures based on same conditions. From January 2012 December 2015, 260 patients with morbid obesity underwent single center. Data patient demography, operation time, complications, hospital stay, body mass...

Laparoscopic repairs for perforated peptic ulcer (PPU) are likely to fail in patients with shock, gastric outlet obstruction, or large perforations. This prospective study was performed evaluate a revised approach of laparoscopic repair endoscopic assistance treat these patients. Between April 2001 and February 2002, 30 consecutive PPU were enrolled this study. The mean age 43.1 +/- 12.2 years. Male female ratio 27:2. One patient excluded from due obstruction. other 29 managed according...

To compare the long-term outcomes and survival rates of patients with end stage renal disease (ESRD) caused by lupus nephritis who received three different modalities replacement therapy, including hemodialysis (HD), peritoneal dialysis (PD), kidney transplantation (KT). We retrospectively analyzed 94 ESRD nephritis. Among these, 42 HD, 12 PD, 40 underwent KT. The adverse events, data cause mortality were recorded. mean age at onset was younger in KT group than HD group. Arteriovenous...

Obesity increases the risk of prolonged emergence from general anesthesia due to delayed release anesthetic agents body fat. This trial aimed evaluate effects sevoflurane and desflurane along with depth monitoring on time in obese patients. Adults a mass index ≥ 30 kg·m-2 undergoing laparoscopic sleeve gastrectomy at medical center were randomized into four groups: or without M-Entropy guidance ratio 1:1:1:1. In groups, dosage was adjusted achieve response state entropy values between 40 60...

According to the statistical distribution laws, all elementary particles in real 3+1-dimensional world must and only be chosen as either bosons or fermions, without exception not both. Here, we experimentally verified that a quantized current-biased Josephson junction (CBJJ), an artificial macroscopic "particle", can served boson fermion, depending on its biased dc-current. By using high vacuum two-angle electron beam evaporations, fabricated CBJJ devices calibrated their physical parameters...

Pelvic Organ Prolapse (POP) is a disabling and chronic condition that affects women of all ages. organs can protrude outside the body through vagina due to weakness in pelvic floor. POP patients both physically psychologically. Most with suffer from at least one other floor disorder, such as incontinence. organ prolapse increases nationwide, namely, anterior, posterior middle compartments prolapse. Plenty different kits had created recent years for reconstruction surgery. Among those...
