BACKGROUND: In patients with leprosy, paralysis of the facial nerve results in the lower eyelid ectropion and lagophthalmos as a sequela even when the leprosy is cured. Paralytic ectropion causes many functional and cosmetic eye problems, leading to blindness if left untreated. OBJECTIVE: The purpose of this retrospective study is to evaluate the efficacy of surgical correction of paralytic ectropion, the lateral tarsal strip, in patients with leprosy. METHODS: Between 2010 and 2015, 40 Korean patients (44 eyelids) with paralytic ectropion who had visited Korean Hansen Welfare Association Hospital were treated with the lateral tarsal strip. Four-point patients' global assessment scale, local complications, and recurrence were assessed at the end of follow-up period. The average follow-up period was 12 months. RESULTS: In the 44 eyelids, recurrence was observed in 5 cases (5/44, 11.4%). There were no serious postoperative complications except mild size discrepancy of both eyes. Most patients were satisfied with the results and mean satisfaction scale was 2.6/3. CONCLUSION: The lateral tarsal strip is a simple, safe, and effective treatment method for the dermatologic surgeon to correct paralytic ectropion of mild to moderate degree in patients with leprosy.

Background: The coronavirus disease 2019 (COVID-19) omicron (B.1.1.529) variant reduced the risk of severe disease compared with the original strain and other variants, but it appeared to be highly infectious, which resulted in an exponential increase in confirmed cases in South Korea. As the number of confirmed cases increased, so did the number of pediatric patients’ hospitalization. This study aims to evaluate the frequency and clinical features of febrile seizure associated with the COVID-19 omicron variant in children. Methods: We retrospectively reviewed the medical records of children aged under 18 years with febrile seizure who were tested for COVID-19 from February 2020 to April 2022 at Ajou University Hospital, South Korea. Based on the dominant variants, we divided the period into the pre-omicron (from February 2020 to December 2021) and omicron periods (from January 2022 to April 2022) and compared the clinical characteristics between the two. Also, we compared the clinical characteristics of febrile seizure between COVID-19 positive and negative group during the omicron period. Results: Among the 308 children, 211 patients (9.2 patients/months) and 97 patients (24.3 patients/months) were grouped into pre-omicron and omicron periods, respectively.Compared with the pre-omicron period, patients in the omicron period showed significantly higher mean age (pre-omicron vs. omicron, 22.0 vs. 28.0 months; P = 0.004) and COVID-19 positive results (pre-omicron vs. omicron, 0.5% vs. 62.9%; P < 0.001). As the COVID-19 confirmed cases in the omicron period increased, the number of COVID-19 associated febrile seizure also increased. In the omicron period, 61 children were confirmed to be positive for COVID-19, and COVID-19 positive group showed statistically significant higher mean age (positive vs. negative, 33.0 vs. 23.0 months; P= 0.003) and peak body temperature than the negative group (positive vs. negative, 39.1°C vs. 38.6°C; P = 0.030). Despite the lack of significance, COVID-19 positive group showed longer seizure time, multiple seizure episodes, and higher prevalence of complex febrile seizure. Conclusion The frequency of COVID-19 associated febrile seizure increased in the omicron periods. In addition, in this period, children with febrile seizure diagnosed with COVID-19 had a higher mean age and higher peak body temperature.

Multiple myeloma (MM) can be defined as a malignancy with monoclonal plasma cell proliferation. A 66-year-old man presented with pruritic erythematous to purplish plaque grouped nodule with black pigmentations and purpura on the right forearm. The patient was diagnosed with MM about five years prior to the visit at our hospital. Erythematous plaque on his right arm grew rapidly in size over one month and appeared about seven months after the fracture surgery. Skin biopsy showed multiple plasma cell infiltration with monoclonality for lambda light chain, which was consistent with cutaneous plasmacytoma. The patient refused to be treated and died two months later. We herein report an interesting case of cutaneous plasmacytoma at the surgical site of fracture repair.

BACKGROUND: Tranexamic acid (TXA), a plasmin inhibitor, has been used orally or via intradermal injection to treat melasma; however, there are limited studies regarding efficacy and safety of topical application of TXA. OBJECTIVE: The purpose of this study is to evaluate the efficacy and safety of topical tranexamic acid in treatment of melasma. METHODS: We enrolled 25 female volunteers with melasma in a split-face trial lasting 10 weeks. Patients were instructed to apply cream containing tranexamic acid on only the right side of their face every night without application on the other side. The pigmentary index (PI) using API-100 and Melasma Area and Severity Index (MASI) were measured at 0, 5, and 10 weeks. Patient satisfaction questionnaires and safety evaluation by a dermatologist were performed at each follow-up visit. RESULTS: Twenty-five patients completed the study, and we noted reduction in both, mean MASI and PI scores. The mean MASI score was 7.75±5.10 at baseline, 6.72±4.25 at week 5, and 6.26±3.76 at week 10 p=0.008). The mean PI score on the right side of the face was 40.56±22.51 at baseline, 29.96±16.62 at week 5, and 26.88±15.97 at week 10. The PI on the right side of the face decreased by 26.1% (p<0.001) at week 5 and 33.7% (p<0.001) at week 10 compared to the baseline. Mean PI score on the unaffected side of the face was 40.56±22.60 at baseline, 37.48±17.79 at week 5, and 34.68±16.44 at week 10, although this reduction was not statistically significant (p=0.146). Only mild irritation occurred in two patients, no other serious adverse events were noted, and patients were generally satisfied with their results. CONCLUSION: Topical TXA can be considered a safe and effective option in the treatment of melasma.

Segmental neurofibromatosis is a rare form of neurofibromatosis that is characterized by neurofibromas and/or café au lait macules, limited to one region of the body. The neurofibromas of segmental neurofibromatosis are most commonly occupied by either a cervical or a thoracic dermatome. Segmental neurofibromatosis on the face is extremely rare, and only 10 cases have been described so far. Herein, we report a case of segmental neurofibromatosis on the V1 dermatome for its rarity and unusual location.

Kaposi's sarcoma is a multifocal proliferative vascular tumor involving the skin and other organ and psoriasis is a chronic cutaneous disease with papules and plaques with white scale. Development of Kaposi's sarcoma in psoriasis patients has been reported rarely. A 71-year-old man presented with multiple brownish to violaceous plaques on both feet and arms which were found 4 months ago. The biopsy confirmed Kaposi's sarcoma. The patient was diagnosed with psoriasis vulgaris 10 years ago and Kaposi's sarcoma lesions developed between psoriatic plaques. We herein report a rare case of simultaneous occurrence of Kaposi's sarcoma and psoriasis vulgaris which need quite different treatment.
