Behcets disease is a chronic systemic disease of unknown etiology, which is characterized by the recurrent orogenital ulcers, eye involvement and skin manifestations. In addition to the major symptoms, it includes arthritis, vasculitis, neurologic manifestations and gastrointestinal lesions. We report a case of Behcets disease associated with intestinal ulcers. The patient, a 45-year-old female, who had been treated under the diagnosis of Behcets disease for 4 years, presented with swallowing difficulty, vaginal discharge and persistent right lower abdominal pain. Colonoscopic examination showed multiple ulcers on the ileocecal region which is reported as the most common site of gastrointestinal Behcets disease. Gastrointestinal evaluation can be useful in diagnosis of Behcets disease, especially in a patient with gastrointestinal symptoms.

BACKGROUND: Urticaria pigmentosa(UP) is primarily a disease of children. There have been no clinical studies of UP in Korea. OBJECTIVE: This study was performed to find the clinical characteristics of UP in Korean child-hood patients. METHOD: Twenty-nine cases of urticaria pigmentosa confirmed clinically and histopathologically were analyzed. RESULTS: The maculopapular type was the most common with the usual age of onset before the age of 6 months, and the lesions tended to be distributed in the central portion of the body. Darier sign was positive in 92% of the patients(24/26). No systemic involvements were detected in any of the patients with minimal associated symptoms. Seven patients of the maculopapular type and one patient of the multiple nodular type followed up for more than 2 years showed a tendency to improve or clear by the age of 6 years. CONCLUSION: Neonatal or infantile-onset patients of UP in Korean pediatric population were considered to have a benign clinical course and to require no aggressive therapy.

As sleep duration and quality are associated with various diseases, many devices have been developed to assess sleep. We reviewed the devices used to assess sleep and their performance, focusing on Fitbit, one of the most popular devices for tracking sleep. Although previous studies have reported conflicting results regarding Fitbit’s estimation of the sleep index, most studies have shown that it has acceptable accuracy and high sensitivity. Its performance could be affected by various factors such as participants’ sleep characteristics, sleep hours and stages, analysis methods, devices compared, device models and settings, and the dominanton-dominant wrist wearing the device. Therefore, these factors should be considered when using Fitbit to assess sleep patterns.
