Clinical Trial Observational Study
Predicting effective remifentanil concentration in 95% of patients to prevent emergence cough after laryngomicroscopic surgery.
Smooth emergence or cough prevention is a clinically important concern in patients undergoing laryngomicroscopic surgery (LMS). The purpose of this study was to estimate the effective concentration of remifentanil in 95% of patients (EC95) for the prevention of emergence cough after LMS under propofol anesthesia using the biased coin design (BCD) up-down method. A total of 40 adult patients scheduled to undergo elective LMS were enrolled. ⋯ Compared with patients receiving lower concentrations of remifentanil, the incidence of hypoventilation before extubation and extubation time were significantly higher in those receiving remifentanil Ce of 3.0 ng/mL. However, hypoventilation incidence after extubation and staying time in the recovery room were comparable between the 2 groups. Using a BCD method, the EC95 of remifentanil Ce for the prevention of emergence cough was estimated to be 2.92 ng/mL (95% CI: 2.72-2.97 ng/mL) after LMS under propofol anesthesia.

Neurofibromatosis, including type 1 and type 2, is inherited dominant disease that causes serious consequences. The genetic mechanism of these diseases has been described, but germline mutation of checkpoint 2 kinase gene, together with other DNA repair related genes, has not been fully elucidated in the context of neurofibromatosis. ⋯ This is the first article to describe CHEK2 mutation in both NF1 and NF2. This article highlights a possible role of CHEK2, in association with other germline genetic mutations, in tumorigenesis of NF1 and NF2.

Case Reports
Obstructive bronchitis and recurrent pneumonia in esophageal achalasia in a child: A CARE compliant case report.
Esophageal achalasia is characterized by impaired relaxation of the cardia and dilation of the intrathoracic part of the esophagus. We describe the late presentation of achalasia in an 11-year old girl. ⋯ Late presentation of achalasia in children can mimic respiratory and gastrointestinal diseases. Laparoscopic Heller myotomy combined with Dor fundoplication is feasible and advisable in children suffering from achalasia of the cardia.

Observational Study
Male patients with rheumatoid arthritis have an increased risk of osteoporosis: Frequency and risk factors.
Most previous research investigating osteoporosis in rheumatoid arthritis (RA) has focused on female patients and there is a lack of data regarding clinical characteristics of osteoporosis in male patients with RA. The aim of this study was to compare the frequency of osteoporosis between male patients with RA and healthy patients, and to identify the risk factors for osteoporosis and low bone mineral density (BMD) in male patients with RA. We conducted a retrospective, cross-sectional study including 76 South Korean male patients with RA aged over 50 years and 76 age-matched male healthy individuals. ⋯ In multivariable logistic regression models, BMI ≤ 22 kg/m (odds ratio = 3.43, P = .043) and DAS28-ESR > 3.2 (odds ratio = 3.85, P = .032) were independent risk factors for osteoporosis at either site in male patients with RA. Our data demonstrate that male patients with RA had a 2.1 times higher risk for osteoporosis compared with healthy individuals. This suggests that appropriate management of osteoporosis in patients with RA is crucial not only for postmenopausal women but also for men aged over 50 years, especially those with low BMI and higher disease activity.

Case Reports
Endoscopic resection of a giant colonic lipoma with endoloop-assisted unroofing technique: A case report.
Colonic lipomas are uncommon benign submucosal adipose tumorsthat are usually asymptomatic. Large lipomas can cause symptoms require treatment in principle. We report 1 case of giant colonic lipoma removed with endoloop-assisted unroofing technique instead of conventional surgical bowel resection. ⋯ Endoscopic resection with endoloop-assisted unroofing technique remains a viable option for giant lipomas; however, postoperative intestinal obstruction caused by shedding mass should be noted.
