A 43 year-old female patient suffered the sudden onset of pulsatile tinnitus in the left ear 2 months ago. The tinnitus did not subside spontaneously and remained unchanged. The patient had no history of head trauma or surgery of the head and neck. The character of the tinnitus was pulsatile, and it was synchronous with the heart beat. Audiologic examinations were performed and all of the results were normal. Computed tomography with angiography was performed and evidence of an arterio-venous fistula (AVF) was found. 4-vessel angiography was performed to confirm the dural AVF between the external carotid artery and sigmoid sinus. Embolization of the feeder-vessels was done under a fluoroscope and 70% of the fistula flow was controlled after embolization and the tinnitus totally subsided during the embolization.

Porocarcinoma (PC) and basal cell carcinoma (BCC) are distinct skin cancers. Few studies have documented the occurrence of two concurrent types of skin cancers, and to the best of our knowledge, this represents the inaugural report of such a coexisting lesion arising from a capillary malformation. Herein, we report a case of concurrent PC and BCC presenting with capillary malformation. A 93-year-old woman visited our hospital with a protruding mass in her right nasal ala that appeared as a capillary malformation. A biopsy was performed on the skin lesion, and BCC was diagnosed. A wide excision was performed. Permanent biopsy revealed that the skin lesion was a PC with basal cells and squamous differentiation. The safety margin of the deep tissue margin was < 0.1 cm; however, considering the advanced age of the patient, further excision was deemed to not possess any benefits. This case illustrates the importance of recognizing the possibility of multiple skin cancers, even in patients with benign lesions such as capillary malformations. The rarity of this presentation highlights the importance of thorough investigation and histopathological examination of skin lesions in guiding appropriate surgical excision.

Objectives: ：This study aims to confirm the effectiveness of a school-based very-short-term dialectical be-havior therapy-skills training (DBT-ST) program for preventing self-harm among children and adolescents, considering factors such as age, sex, self-harm history, and methods of program implementation. Methods: ：The study was conducted from September 2021 to December 2023, targeting 1,012 elementary and middle school students in the Chungcheong region. Changes in responses to the Depressed Mood Questionnaire(RDQ), the Difficulties in Emotion Regulation Scale-16 (DERS-16), ‘future self-harm possibility’ scores wereanalyzed and compared before and after the program, based on age, sex, self-harm history, and methods of program implementation. Results: ：Overall, participants showed a decrease in the ‘rumination(RDQ) scale’ (t=10.49, p<0.001), ‘reversescored distraction (RDQ)’ (t=10.67, p<0.001) and the total DERS-16 (t=5.56, p<0.001) as well as a decrease in ‘future self-harm possibility’ score (t=4.26, p<0.001). Both elementary and middle school students showed decrease in ’rumination (RDQ)’ and distraction (RDQ), but only middle school students showed a decrease in theDERS-16 and most sub-scales. Regardless of sex, self-harm history, or methods of program implementation, adecrease in ’rumination (RDQ)’, distraction (RDQ) and the total DERS-16 scale and most sub-scales decreased. Conclusions ：Our program appears to be effective as a primary prevention program for preventing self-harm among children and adolescents in a school setting.

Fournier’s gangrene (FG) is a rare but life-threatening bacterial infection affecting the genital and perianal areas, often associated with high morbidity and mortality rates. Although pressure sores, injuries caused by prolonged pressure on the skin, are considered a risk factor for FG, they are rarely the direct cause of the condition. This case report presents a 65-year-old male with paraplegia and a chronic ischial pressure sore who presented with FG. The patient was treated with prompt surgical debridement and antibiotic therapy, followed by wound reconstruction using a local advancement flap. This enabled a successful outcome, with no further wound issues observed for 6 months. Early diagnosis, imaging modalities, prompt surgical intervention, and appropriate antibiotic therapy are essential for the successful management of FG. This case emphasizes the importance of recognizing the possibility of FG arising from pressure sores and highlights the critical role of early surgical intervention.
