Schwannomas are soft tissue sarcomas arising from neurilemma of Schwann cells in peripheral nerves, and is the most frequent type of benign tumor found in these nerves. We report a case of a Schwannoma of the ulnar nerve in the elbow joint, and along this report, give a review of the literature. A 46-year-old male patient was hospitalized with complaints of swelling and pain in the left elbow and a tingling sensation and hypoesthesia of the fourth and fifth fingers. Physical examination of the patient showed he was positive for Tinel's sign, and magnetic resonance imaging results demonstrated the presence of a Schwannoma. Subsequent biopsy and excision of the Schwannoma was carried out. The suspected mass, which had a clear margin separating it from the healthy nerve of the medial left elbow, was removed along with its 2 x 2 x 3 cm capsule after a histological diagnosis of a Schwannoma was made. Pathophysiological results confirmed the excised mass as a Schwannoma. Schwannoma of the ulnar nerve within the elbow joint is rare and differential diagnosis is difficult. Therefore, treatment can only proceed after the presence of Schwannoma has been confirmed by physical and radiological examinations.

Purpose:
This study compared the short- and long-term clinical outcomes of laser hemorrhoidoplasty (LH) vs. conventional hemorrhoidectomy (CH) in patients with grade II/III hemorrhoids.
Methods:
PubMed/Medline and the Cochrane Library were searched for randomized and nonrandomized studies comparing LH against CH in grade II/III hemorrhoids. The primary outcomes included postoperative use of analgesia, postoperative morbidity (bleeding, urinary retention, pain, thrombosis), and time of return to work/daily activities.
Results:
Nine studies totaling 661 patients (LH, 336 and CH, 325) were included. The LH group had shorter operative time (P<0.001) and less intraoperative blood loss (P<0.001). Postoperative pain was lower in the LH group, with lower postoperative day 1 (mean difference [MD], –2.09; 95% confidence interval [CI], –3.44 to –0.75; P=0.002) and postoperative day 7 (MD, –3.94; 95% CI, –6.36 to –1.52; P=0.001) visual analogue scores and use of analgesia (risk ratio [RR], 0.59; 95% CI, 0.42–0.81; P=0.001). The risk of postoperative bleeding was also lower in the LH group (RR, 0.18; 95% CI, 0.12– 0.28; P<0.001), with a quicker return to work or daily activities (P=0.002). The 12-month risks of bleeding (P>0.999) and prolapse (P=0.240), and the likelihood of complete resolution at 12 months, were similar (P=0.240).
Conclusion
LH offers more favorable short-term clinical outcomes than CH, with reduced morbidity and pain and earlier return to work or daily activities. Medium-term symptom recurrence at 12 months was similar. Our results should be verified in future well-designed trials with larger samples.

INTRODUCTIONThe present study aimed to assess the demographic, socioeconomic, medical and lifestyle factors associated with the progression of a threatened miscarriage to a complete miscarriage in the first trimester.
METHODSA prospective cohort study was conducted on 157 women who presented with vaginal bleeding in the fifth to tenth week of gestation. Cox regression analysis was used to determine the risk factors for progression to a complete miscarriage within 16 weeks of gestation.
RESULTSOf the 139 women included for data analysis, 36 (25.9%) had a miscarriage, mostly within two weeks of presentation. The results of our study showed that women aged ≥ 34 years were more likely to miscarry (hazard ratio [HR] = 1.95). Compared to women whose partner was 20-30 years of age, women whose partner was ≥ 41 years of age also had a higher likelihood of experiencing a miscarriage (HR = 8.33). However, the presence of nausea (HR = 0.33) and a high stress score (i.e. ≥ 17) on the Perceived Stress Scale (HR = 0.49) were associated with a reduced likelihood of miscarriage.
CONCLUSIONOlder pregnant women experiencing a threatened miscarriage should be counselled about their higher risk of miscarriage, especially if they have an older partner.

In 2010, the Asian Society of Cardiovascular Imaging (ASCI) provided recommendations for cardiac CT and MRI, and this document reflects an update of the 2010 ASCI appropriate use criteria (AUC). In 2016, the ASCI formed a new working group for revision of AUC for noninvasive cardiac imaging. A major change that we made in this document is the rating of various noninvasive tests (exercise electrocardiogram, echocardiography, positron emission tomography, single-photon emission computed tomography, radionuclide imaging, cardiac magnetic resonance, and cardiac computed tomography/angiography), compared side by side for their applications in various clinical scenarios. Ninety-five clinical scenarios were developed from eight selected pre-existing guidelines and classified into four sections as follows: 1) detection of coronary artery disease, symptomatic or asymptomatic; 2) cardiac evaluation in various clinical scenarios; 3) use of imaging modality according to prior testing; and 4) evaluation of cardiac structure and function. The clinical scenarios were scored by a separate rating committee on a scale of 1–9 to designate appropriate use, uncertain use, or inappropriate use according to a modified Delphi method. Overall, the AUC ratings for CT were higher than those of previous guidelines. These new AUC provide guidance for clinicians choosing among available testing modalities for various cardiac diseases and are also unique, given that most previous AUC for noninvasive imaging include only one imaging technique. As cardiac imaging is multimodal in nature, we believe that these AUC will be more useful for clinical decision making.
