BACKGROUND: Cardiopulmonary resuscitation (CPR) is one of the most important medical procedures. However, we could not find any survival rates from in-hospital cardiopulmonary resuscitation in Korea. The objective of this study was to report outcomes according to a Utstein template for in-hospital CPR and to use this report as basic material to enhance our CPR skills and outcome. METHODS: We reviewed all medical records of arrest cases in our hospital in 2001, which were coded as CPR, care for arrest, defibrillation/cardioversion, and Ambu. The data was summarized and analyzed in Utstein style. Most of the data was described in percentage, and the t-test was used to compare survival rate by sex. A P-value below 0.05 was considered significant. RESULTS: In 2001, 218 patients was resuscitated in our hospital and 53 patients (24.3%) survived after CPR. Their mean survival was 10 days. Twenty-seven victims died within the first 24 hours after resuscitation. Nobody was discharged alive from our hospital. The time interval from collapse to CPR was 1.7 minutes, to intubation, 5.62 minutes, to epinephrine injection 7.4 minutes and to defibrillation, 23 minutes. Glascow coma scale and cerebral performance category were less than 8 and 4 for a majority of patients. CONCLUSIONS: In our hospital, we had a low survival rate and quality of life. To improve outcome, we should prepare a better education program and more equipment and well-trained personnel for CPR.

Background: Sweet syndrome is characterized by tender erythematous plaques and nodules with predominantly dermal neutrophilic infiltrates. Sweet syndrome is relatively rare in children and adolescents. To date, only a few cases have been reported in Korean literature. Objective: The aim of this study was to investigate the clinical and histopathological features of Sweet syndrome in Korean children and adolescents. Methods: A retrospective study was conducted on 15 pediatric patients (aged ＜18 years) who were diagnosed with Sweet syndrome between 1991 and 2019. We reviewed the clinical and histopathological features of Sweet syndrome. Results: The age of the 15 patients ranged from 4 months to 17 years. Among the 15 patients with Sweet syndrome, nine patients were females and six patients were males. Most patients (80%) had lesions on the upper extremities. Fever and tenderness (60%) were the most commonly associated symptoms. Transient infections such as upper respiratory infection or gastroenteritis were the most common identifiable cause, observed in 40% of patients. Histopathologically, dermal neutrophilic infiltration was observed in all patients. All patients were treated with systemic corticosteroids and showed a good response, although 26.7% of the patients experienced symptom recurrence.During the follow-up period, there were no incidences of any complications or extracutaneous manifestations in the patients. Conclusion In contrast to previous reports of pediatric Sweet syndrome, female predominance was observed in this study. Transient infection was the most common factor. All patients responded well to systemic corticosteroid therapy without complications or extracutaneous manifestations during the follow-up period.

Milia are benign primary or secondary keratinous cysts. Multiple eruptive milia (MEM) and milia en plaque (MEP) are rarely reported. A 21-year-old male presented with multiple skin-colored papules on the abdomen and both acral regions, and erythematous plaques featuring similar papules on the wrist and the dorsa of the feet. A biopsy confirmed MEP and he was diagnosed with both MEM and MEP. We thus report a rare case of simultaneous MEM and MEP.

Perforating granuloma annulare (PGA), a rare variant of granuloma annulare, is characterized by transepidermal elimination of altered collagen that clinically manifests an umbilicated papule with a central crust. It can be confused with papulonecrotic tuberculid (PNT) because of their similar appearance. Unlike PGA, PNT is usually related to tuberculosis infection with a typical histologic finding of wedge-shaped dermal necrosis. Here, we report the first Korean case of PGA mimicking PNT both clinically and histologically. A 43-year-old Korean woman presented with erythematous papules localized on the extensor surface of her limbs for one year. Some of these papules had a central umbilication or a crust. Regarding comorbidity, she had latent tuberculosis diagnosed with QuantiFERON®-TB Gold test about five months ago. She was on antituberculous medication. Initially, a diagnosis of papulonecrotic tuberculid accompanied by latent tuberculosis was considered. However, despite taking the antituberculous medication for five months, her skin lesions were not improved. Biopsy specimen from her arm lesion showed wedge-shaped area of necrosis in the dermis. Additionally, there were multiple focal mucin depositions and palisading granulomatous inflammation throughout the dermis. A diagnosis of PGA was made and she was treated with topical corticosteroid. After two weeks of applying topical corticosteroid, most of her skin lesions disappeared, leaving some hyperpigmented scars.

Porokeratosis is a rare epidermal disorder characterized by annular or linear hyperkeratotic plaques with slightly raised thread-like borders, and in most cases, atrophic centers. Disseminated superficial porokeratosis and disseminated superficial actinic porokeratosis (DSAP), which primarily involve sun-exposed areas, are common types of porokeratoses. Histologically, a column of parakeratotic cells, a so-called cornoid lamella, is a hallmark of porokeratosis. Porokeratosis is considered to result from the inability to eliminate an abnormal keratinocyte clone induced by genetic factors and various stimuli, including sunlight, artificial ultraviolet light, viral infections, immunosuppressive conditions (hematologic malignancies, organ transplants, or autoimmune disease), and immunosuppressive therapies. Here, we report a 59-year-old Korean woman with DSAP that developed after narrowband ultraviolet B (NB-UVB) therapy for psoriasis. Our case emphasizes the occurrence of DSAP due to NB-UVB that is able to induce local immunosuppression at the irradiated site; the pathogenesis of DSAP remains unclear.

Lenalidomide is an immunomodulatory drug used for the treatment of multiple myeloma. Several cases of hematological, gastrointestinal, and cutaneous side effects have been reported for this drug. A 67-year-old patient with multiple myeloma had initially been treated with bortezomib, but the treatment was discontinued due to neurological side effects. The chemotherapeutic regimen of this patient was changed to lenalidomide. Ten days later, erythema and pruritus developed on the entire body. The lenalidomide dose was subsequently reduced and the patient was additionally treated with topical steroids. Because lenalidomide is supplied by the Korean Orphan Drug Center, physicians have limited experience with the drug, and hence, its side effects tend to be underestimated. In addition, the Korean literature lacks reports on such cases. We describe herein a case of lenalidomide-induced drug eruption presenting as a pruritic rash covering the whole body.
