A prospective study was carried out on the efficacy of a circular grip which we devised to facilitate a non-sterile intermittent catheterization. The series included 16 females, the mean follow-up time being 7 months. Most patients were suffering from neurogenic bladder disorders and bladder retention after operation. All of them used the circular grip during intermittent catheterization and continued to undergo intermittent catheterization. The technique of the use of the circular grip during intermittent catheterization was usually learnt easily and provided reassurance to the patient and family about intermittent catheterization.

PURPOSE: We retrospectively evaluated the 45 patients who underwent the original Raz procedure and anterior vaginal wall sling(AVWS) operation for stress urinary incontinence(SUI) with or without cystocele. MATERIALS AND METHODS: Transvaginal bladder neck suspension was performed in 14 patients, 4-corner bladder and bladder neck suspension in 16 patients, anterior vaginal wall sling in 14 patients, and 6-corner suspension in one patient. Of 16 patients who underwent 4-corner operation, 11 had grade 2 cystocele, and 5 had grade 3 cystocele. RESULTS: Mean age was 49 years and mean parity was 2.7. Duration of symptom was 58.5 months in average. Patients with grade l was 27%(12), grade ll was 69%(31) and grade lll was 4%(2). Mean operation times were 92. 1minutes in Raz bladder neck suspension, 90.9minutes in 4-corner bladder and bladder neck suspension, and 76.2minutes in anterior vaginal wall sling. The duration of follow up was 20 months in average. Urinary incontinence was completely disappeared in 40 patients(91%), and significantly improved in 3 patients(7%), but one patient(2%) underwent Raz BNS was recurred. Complications include a case of severe bleeding requiring intraoperative transfusion, 2 cases of prolonged retention, 2 cases of do novo urgency and 2 cases of persistent weak urinary stream. CONCLUSIONS: Our midterm result for Raz BNS and 4-corner operation was good(96.7%) and short term result for AVWS was excellent(100%). We think that original Raz BNS may be used in patients with mild SUI without ISD. And, long term follow-up for AVWS operation is required to determine persistence of the good results in patients with moderate to severe SUI.

Background: Although the older adult population in Korea is growing, few studies have investigated the profile of late-onset vitiligo (onset at 50 years of age or above) to date. Objective: The present study aimed to describe the clinical characteristics and course of patients with late-onset vitiligo in Korea. Methods: The present single-center retrospective study included 132 patients with late-onset vitiligo from January 1, 2009 to November 30, 2022. We analyzed patient demographics and vitiligo characteristics. Further, we evaluated the progress of late-onset vitiligo using the Vitiligo Area Severity Index (VASI) score. Results: The study included more females (n=83, 62.9%) than males (n=49, 37.1%), with an average age of onset 60.9±7.4 years. The average duration of the disease before presentation was 15.0±27.3 months. A family history of vitiligo was identified in eight patients (6.1%), and seven patients (5.3%) had associated autoimmune diseases.Acrofacial vitiligo was the most common type (n=56, 43.1%), and the head and neck area were the commonly affected site at disease onset (n=93, 70.5%). The Koebner phenomenon was observed in seven patients (5.3%), and chemical-induced vitiligo was suspected in three patients (2.3%). Treatment was administered to 131 patients (99.2%). The VASI score decreased in 93 patients (83.0%), with an average decline rate of 58.56%. Conclusion Late-onset vitiligo tends to be of the acrofacial vitiligo subtype in the Korean population. Patients demonstrated a strong desire to treat vitiligo, and treatment response was promising. Further larger-scale studies to elucidate the characteristics and progression of late-onset vitiligo may be needed.

Actinomycosis is a chronic suppurative and granulomatous disease caused by gram-positive bacteria, the Actinomyces, which normally resides in the mouth cavity and large bowel. Actinomyces and other bacterial species are concomitantly, on occasion, found, having been designated "companion microbes". Designing a therapeutic regimen that includes coverage for "companion microbes" during the initial treatment course is reasonable. Primary hepatic actinomycosis, which was not found in possible source or associated disease and was coinfected with alpha-strepotcoccus, has not yet been reported in Korea. We report a case of primary hepatic actinomycosis coinfected with alpha-streptococcus presenting fever, chill, right upper quadrant abdominal pain as chief complaints in a 63-year-old woman. Primary hepatic actinomycosis was confirmed by identification of the sulfur granule, which was obtained by ultrasonography-guided percutaneous needle aspiration and biopsy.

Atypical fibroxanthoma (AFX) is a rare fibrohistiocytic tumor usually observed on ultraviolet light-exposed areas of the body, such as the face or scalp in elderly individuals. Despite its clinically benign course, AFX presents with malignant features on histopathological evaluation. A 12-year-old male adolescent presented with a 3-month history of an asymptomatic, skin-colored, oval-shaped nodule on his right thigh. Histopathological examination showed a dermal tumor adjacent to the epidermis, without epidermal invasion. The tumor was composed of numerous pleomorphic spindle cells and large atypical histiocytes with abundant vacuolated cytoplasm and pleomorphic nuclei. Immunohistochemical analysis revealed tumor cells, which were immunopositive for vimentin, CD68, CD10 and immunonegative for desmin, pan-cytokeratin antibody (AE1/AE3), and S-100. Therefore, the patient was diagnosed with AFX. We report a rare case of AFX that occurred on the thigh (an unusual site) in an adolescent (an uncommon age group). Immunohistochemical analysis is important in patients with suspected AFX, regardless of the patient’s age and site of lesion, for accurate diagnosis to differentiate this condition from other diseases with a similar presentation.

The cutaneous appearance of transient or persistent livedo reticularis is characterized by violaceous, mottled, ring-shaped interconnecting lesions that form a reticular or net-like pattern. It can occur physiologically in response to cold exposure, such as in cutis marmorata, but can also be induced by pathological conditions such as vascular obliterans or venodilation. We report two cases of livedo reticularis that occurred on the lower limbs of two patients post ChAdOx1 nCoV-19 vaccination. As the patients had no other likely causes of livedo reticularis, the reticular skin lesions were suspected to occur in association with the ChAdOx1 nCoV-19 vaccination. Livedo reticularis is an uncommon adverse reaction, with few cases being reported post ChAdOx1 nCoV-19 vaccination.
