Purpose: The purpose of this study was to prepare guidelines for the treatment of COVID-19-positive hip fractures based on the treatment experience of patients with COVID-19-positive hip fractures admitted to a COVID-19-dedicated hospital. Materials and Methods: A retrospective analysis was performed on COVID-19-positive elderly hip fracture patients treated at a COVIDdedicated hospital when the number of domestic COVID-19 infections increased rapidly. The treatment results were analyzed by comparing the complications of patients who underwent surgery at a COVID-dedicated hospital and those who did not, the time taken from surgery to surgery, and the number of visits to medical institutions. Results: The average surgery time for COVID-19 hip fracture patients in the author’s hospital was 3.74 days from the date of injury, and it took an average of 12.8 days for surgery at other hospitals. The average number of patients who visited medical institutions was 3.33 locations in the group who did not undergo surgery at the author’s hospital, which was significantly higher than the 2.83 locations in the group who had surgery. Among the patients unable to undergo surgery, no patient could not undergo surgery due to serious reasons. Conclusion The explosive increase in COVID-19 infections has delayed the time of surgery for COVID-19-positive elderly patients with hip fractures and increased the transfer rate of medical institutions, even for relatively non-dangerous causes. Clear criteria for treatment and effective policies are needed to prevent delay delays in treatment.

Despite the well-known bleeding diathesis in patients with end-stage liver disease, inappropriate hypercoagulation is also emerging as a major concern. Pulmonary thromboembolism (PTE) is a major cause of perioperative morbidity and mortality during liver transplantation (LT). Flat-line thromboelastography is reported to predict PTE during LT. In this case, a 52-year-old woman with hepatocellular carcinoma underwent living-related LT. During the pre-anhepatic phase, one unit of apheresis platelets was transfused because of thrombocytopenia (32,000 /ml). After 20 minutes, blood pressure became unstable and circulatory collapse suddenly developed. In the middle of cardiopulmonary resuscitation, transesophageal echocardiography was immediately conducted, which revealed flail thrombi in the right atrium. Rotational thromboelastometry (ROTEM) conducted at that time was surprisingly flat in 4 channels, contradictory to the finding of hypercoagulation. This finding lead to a management dilemma during LT. Flattening in ROTEM requires caution in interpretation of severe hypocoagulation or ongoing PTE.

BACKGROUND/AIMS: Superficial esophageal squamous cell carcinoma (SESCC) is being increasingly detected during screening endoscopy. Endoscopic submucosal dissection (ESD) allows for en bloc and histologically complete resection of lesions. This study assessed the technical feasibility and long-term outcomes of ESD for SESCCs. METHODS: Between January 2005 and August 2012, 27 patients with 28 SESCCs underwent ESD at Pusan National University Hospital. The en bloc and pathologically complete resection rates, complication (perforation and bleeding) rate, incidence of esophageal stricture after ESD, and overall and disease-specific survival rates were evaluated. RESULTS: The en bloc and pathologically complete resection rates were 93% and 83%, respectively. No significant bleeding occurred, and perforation with mediastinal emphysema was observed in two patients (7%). Post-ESD stricture occurred in two patients (7%) who had mucosal defects involving more than three-fourths of the esophageal circumference. During a mean follow-up of 23 months, local tumor recurrence was seen in two of four lesions with pathologically incomplete resection; one was treated by re-ESD, and the other was treated by surgical esophagectomy. The 5-year overall and disease-specific survival rates were 84% and 100%, respectively. CONCLUSIONS: ESD seems to be a feasible, effective curative treatment for SESCCs. All patients should be closely followed after ESD.

A coronary arteriovenous fistula consists of a communication between a coronary artery and a cardiac chamber, a great artery or the vena cava. It is the most common anomaly that can affect coronary perfusion. Bilateral involvement of coronary fistula, however, constitutes an uncommon subgroup of coronary arteriovenous fistulas. We report a case which shows a rare occurrence of bilateral coronary arteriovenous fistula coexistent with atrial septal defect and pulmonic stenosis.

BACKGROUND: The advantages of horizontal, over vertical, sectioning of scalp biopsies allow morphometric analysis of follicular structures. OBJECTIVE: In this study, we performed the morphometric analysis of alopecia areata and androgenetic alopecia in Koreans using the horizontal sectioning method. METHODS: Paird, 4-mm punch biopises were taken from the margin of alopecic patch from 21 alopecia areata patients or the frontal lesion of 13 androgenetic alopcia patients, and from clinically normal occipital scalp of all subjects. RESULTS: The general histopathological features were consistent with the known descriptions, but the data on exact follicular counts showed striking differences compared with those from Caucasians. 1. In alopecia areata, numbers of vellus hairs (3.2+/-2.9) and follicular stellae (1.6+/-1.6) was increased significantly (p<0.05) compared with counts from normal occipital scalp (vellus hairs 1.1+/-1.3; follicular stellae 0.5+/-0.8). Anagen/telogen percent ratio was decreased in lesions (64.2%:35.8%) compared with normal occipital scalp (94.0%:5.7%). 2. In androgenetic alopecia, numbers of vellus hairs (4.1+/-3.7) and follicular stellae (4.4+/-3.4) was increased significantly (p<0.05) in the lesion compared with the normal occipital scalp (vellus hairs 1.1+/-1.3; follicular stellae 1.0+/-1.2). Mild decrease of anagen/telogen percent ratio was observed in lesions (86.5%:13.5%) compared with normal occipital scalp (93.5%:6.5%). CONCLUSION: Our results suggest that horizontal sectioning of scalp biopsies is a useful diagnostic method but differences in follicular counts should be considered in interpreting the morphometric data in Koreans.

Intramural pregnancy is one of the rarest forms of ectopic pregnancy. The pathologic diagnosis of the intramural ectopic pregnancy requires that the myometrium surrounds the products of conception separated from the endometrial cavity or fallopian tubes. Because the early diagnosis is very difficult, most cases are found after the onset of complications such as a uterine rupture or hemoperitoneum. The previous histories of curettage, cesarean section, myomectomy, salpingectomy and manual removal of the placenta are known as possible etiology of the intramural pregnancy. We have recently experienced a case of intramural pregnancy after 10 times of curettages and are reporting with a brief review of the literatures.

PURPOSE: The increased tolerability of enteric-coated mycophenolate sodium (EC-MPS), compared to mycophenolate mofetil, among kidney transplant recipients has the potential to facilitate cyclosporine (CsA) minimization. Therefore, a prospective trial to determine the optimum EC-MPS dose in CsA-based immunosuppression regimens is necessary. MATERIALS AND METHODS: A comparative, parallel, randomized, open-label study was performed for 140 patients from four centers to compare the efficacy and tolerability of low dose CsA with standard dose EC-MPS (the investigational group) versus standard dose CsA with low dose EC-MPS (the control group) for six months in de novo kidney transplant recipients. Graft function, the incidence of efficacy failure [biopsy-confirmed acute rejection (BCAR), death, graft loss, loss to follow-up], and adverse events were compared. RESULTS: The mean estimated glomerular filtration rate (eGFR) of the investigational group at six months post-transplantation was non-inferior to that of the control group (confidence interval between 57.3 mL/min/1.73m² and 67.4 mL/min/1.73 m², p<0.001). One graft loss was reported in the control group, and no patient deaths were reported in either group. The incidence of BCAR of the investigational group was 8.7%, compared to 18.8% in the control group (p=0.137), during the study period. There were no significant differences (p>0.05) in the incidence of discontinuations and serious adverse events (SAE) between the groups. CONCLUSION: CsA minimization using a standard dose of EC-MPS kept the incidence of acute rejection and additional risks as low as conventional immunosuppression and provided therapeutic equivalence in terms of renal graft function and safety issues.

OBJECTIVE: The Korean College of Neuropsychopharmacology developed a Korean treatment algorithm for obsessive-compulsive disorder (OCD) to aid clinical decisions. The goal of this preliminary study was to encourage clinical practitioners to treat patients using cognitive-behavioral therapy. METHODS: We sent a questionnaire to 34 leading experts on OCD to investigate their opinions about treating patients with OCD using cognitive-behavioral therapy. RESULTS: Of the 34 experts, 12 responded to the survey. The responses indicated that most patients with obsessive-compulsive disorder should be offered cognitive-behavioral therapy, incorporating intensive and sufficient cognitive therapy with response prevention. CONCLUSION: These results may provide information about the application of cognitive-behavioral therapy to treat obsessive-compulsive disorder.
