Recently, in Korea, the importance of preparation and use of injectable drugs has been emphasized due to successive fatal accidents caused by injection infections. Parenteral nutrition (PN) has also been identified as a cause of infection. Cases of infection due to PN have been reported not only in Korea, but also abroad, and contamination occurs mainly during the preparation of PN. Because sterile preparation and compounding of injections are very important for infection control and patient safety, this article reviews the major guidelines outlined thus far. The Korea Ministry of Food and Drug Safety in 2006 published guidelines and the KSHP (Korean Society of Health-System Pharmacists) recently issued guidelines for the aseptic preparation of injections. In addition, as US guidelines, the ASHP (American Society of Health-System Pharmacists) guidelines and United States Pharmacopeia (USP) < 797 > are also reviewed. The recent guidelines published by the KSHP have significance in that they were adopted in accordance with the domestic reality, even though they conform to foreign guidelines, and are expected to be guidelines for hospital pharmacists performing aseptic preparation work. In addition, the Korea Ministry of Health and Welfare is considering appropriate guidelines for the safe management of medications, training staff for infection prevention and strengthening staff capacity. Furthermore, the gradual expansion of aseptic compounding facilities and human resources, as well as the provision of adequate medical costs are also considered. Based on the establishment and standardization of injectable drugs compounding guidelines for Korean hospitals, it is believed that if human resources and facilities are supported and medical charges are improved, it will be possible to expect the safer preparation and use of injections.

Background: Folliculitis decalvans and dissecting cellulitis are types of primary neutrophilic cicatricial alopecia characterized by permanent hair loss. Clinicopathological differentiation is poorly described in literature. Objective: This study aimed to determine the clinicopathological distinction between folliculitis decalvans and dissecting cellulitis. Methods: A retrospective review was conducted in 45 patients diagnosed with dissecting cellulitis and folliculitis decalvans between 2011 and 2021. We reviewed the clinical features using electronic medical records, clinical photographs, and histopathologic features. Results: Clinically, middle-aged men with folliculitis decalvans showed polytrichia (80%) and papulopustules (55%), while young men with dissecting cellulitis had deeply seated nodules (84%). Histopathologically, follicular plugging was more frequently observed in dissecting cellulitis (80%) than in folliculitis decalvans (50%). There was a difference in the depth of inflammation between the two types. Conclusion A difference in clinical manifestations was observed according to the depth of inflammation. These findings may contribute to the differential diagnosis of primary neutrophilic cicatricial alopecia.

Purpose: This longitudinal cohort study aimed to evaluate the relationship between osteonecrosis of the jaw and pulp and periapical disease in patients who were administered bisphosphonates. Methods: Using data from a nationwide cohort, we examined the association among dental caries, pulp and periapical disease, and osteonecrosis of the jaw in women aged >50 years who received bisphosphonates for more than 1 year between 2002 and 2015.Because of ambiguities in the diagnosis of osteonecrosis of the jaw in population-based data, we operationally defined and categorized the condition into established and potential osteonecrosis of the jaw. Results: Pulp and periapical disease significantly increased the development of both established and potential osteonecrosis of the jaw (hazard ratio, 2.21; 95% confidence interval, 1.40–3.48; and hazard ratio, 2.22; 95% confidence interval, 1.65–2.98, respectively). Root canal treatment did not have any influence on the development of osteonecrosis of the jaw. Conclusions Pulp and periapical disease may be a major risk factor for osteonecrosis of the jaw. The study findings suggest that patients should undergo regular dental examinations to detect pulp and periapical disease before or during the administration of bisphosphonates and that root canal treatment should be considered to decrease the risk of osteonecrosis of the jaw.

Biliary enteric fistula is an abnormal pathway often caused by biliary disease. It is difficult to diagnose the disease because patients have nonspecific symptoms. A 67-year-old woman presented with hematemesis and melena. She was diagnosed with Dieulafoy lesion on the gastric antrum and underwent endoscopic hemostasis using hemoclips. Follow-up upper gastrointestinal endoscopy revealed an abnormal opening on a previous treated site that was suggestive of biliary enteric fistula. Abdomen simple X-ray and abdominal dynamic CT scan showed pneumobilia and cholecysto-gastric fistula. The patient had cholecystectomy and wedge resection of the gastric antrum, followed by right extended hemicolectomy because of severe adhesive lesion between the gallbladder and colon. She was diagnosed with cholecysto-gastro-colic fistula postoperatively. We report on this case and give a brief review of the literatures.

PURPOSE: To investigate mid-term clinical outcomes of various methods of scapholunate reconstruction for chronic scapholunate instability. METHODS: We retrospectively reviewed 11 patients diagnosed as chronic scapholunate instability, from 2005 to 2013 and followed up for more than one year after surgery. 7 patients were treated with Garcia technique of triple ligament reconstruction, 2, bone-ligamemt-bone repair, and 2, dorsal capsulodesis. Mean age was 42 years (range, 23-61 years). The right side was involved in 6 patients, and the left in 5. The follow-up period averaged 42 months (range, 13-125 months). The postoperative functional outcomes were assessed with Modified Mayo wrist score (MMWS), disability of the arm, shoulder and hand (DASH) score and range of motion. The postoperative radiologic results were analyzed with the change of scapholunate angle and distance. RESULTS: The mean MMWS score improved from 65 preoperatively to 77 postoperatively (p=0.072). The mean DASH score improved from 29.4 (range, 18.3-43.3) preoperatively to 12.7 (range, 0-38.3) postoperatively (p=0.003). The dorsiflexion increased from 67° to 78°, the volar flexion decreased from 51° to 45°, the supination increased from 69° to 88°, and the pronation increased from 62° to 66°. The SL angle changed from 55° preoperatively to 51° postoperatively, the mean SL distance changed from 3.4 mm preoperatively to 1.7 mm postoperatively. CONCLUSION: The chronic scapholunate instability is amenable to various techniques and postoperative functional outcomes improved satisfactory.

Nodular hidradenoma is a relatively infrequent benign tumor that shows differentiation from or toward the structure of the eccrine sweat gland. We report a case of nodular hidradenoma with apocrine differentiation in a 74-year old female who had an asymptomatic, 3.5x2.7x1.0cm-sized, smooth-surfaced, round, erythematous to bluish tumor mass with cystic grape-like nature on the right thigh for 3 years. Histological findings showed a well-circumscribed tumor composed of solid portions with fusiform basophilic cells and clear round cells, cystic spaces, tubular lumina, squamoid feature and decapitation secretion.

Background: Aimed to report the prevalence and predisposing factors affecting subscapularis muscle atrophy and fatty infiltration (MAFI) in patients without a subscapularis tear, and to analyze the effect of this condition on surgical outcomes. Methods: Between 2020 and 2022, 153 patients (mean age 58.1 ± 10.2 years; 84 men and 69 women) who underwent repair of posterosuperior cuff tears, with no subscapularis tears identified during arthroscopy were retrospectively analyzed. Baseline characteristics, preoperative and follow-up (6 months) magnetic resonance imaging findings, arthroscopic findings, and clinical outcomes (>1 year) were recorded. Results: The prevalence of subscapularis MAFI (Goutallier grade 1 or 2) was 73.9% (113/153), of which the prevalence of Goutallier grade 2 was 23.5% (36/153). From multivariable logistic regression analysis, female sex (odds ratio [OR], 5.6; 95% CI, 1.7–18.6; P=0.005), older age (OR, 1.1; 95% CI, 1.0–1.1; P=0.052), advanced supraspinatus MAFI by Goutallier grade (OR, 3.2; 95% CI, 1.5–6.9; P=0.004), and synovitis (OR, 2.8; 95% CI, 1.1–7.9; P=0.030) were identified as independent predisposing factors for subscapularis MAFI. However, patients with preoperative subscapularis MAFI exhibited similar final range of motion, pain and function, and belly press strength compared to those without preoperative subscapularis MAFI. Conclusions Subscapularis MAFI is frequently observed conditions even in the absence of subscapularis tears, and this condition could be affected by supraspinatus MAFI, female sex, older age, and synovitis. However, because subscapularis MAFI does not affect the surgical outcome, surgeons need not be concerned about this condition when repairing posterosuperior rotator cuff tear.Level of evidence: IV.
