Narrow Band Imaging and White Light Colonoscopy for Detection of Polyps / 대한소화기내시경학회지

BACKGROUND/AIMS: Narrow band imaging (NBI) is a new technique that is expected to improve the detection rate of colorectal polyps, but results have been inconsistent. The aim of this study was to compare the polyp miss rate and the characteristics of missed colorectal polyps using white light (WL) and NBI. METHODS: 62 patients were randomized into two groups. In the first group (NBI first, NBIF), a colonoscopic examination of each segment (cecum-ascending, transverse, descending, and rectosigmoid colons) was performed first with NBI followed by a re-examination of the same segment using WL. An opposite sequence was applied for the other group (white light first, WLF). RESULTS: 67 polyps were found in the first examination, and 31 polyps were found on the re-examination, resulting in a polyp miss rate of 31.6%. The polyp miss rate was 39% for WLF and 23% for NBIF (p>0.05). Seventy-four small polyps (<5 mm) were found, and miss rates for NBIF and WLF were 20% and 46%, respectively (p=0.01). The polyp miss rate at the rectosigmoid was 11% for NBIF and 54% for WLF (p=0.01). CONCLUSIONS: The polyp miss rate was not significantly different between NBI or WL when a colonoscopy was performed. NBI resulted in a lower polyp miss rate for small (<5 mm) and rectosigmoid polyps than WL.

A Case of Cyclic Vomiting Syndrome Responding to Gonadotropin-Releasing Hormone Analogue

Cyclic vomiting syndrome (CVS) is a disorder characterized by recurrent episodes of incapacitating nausea and vomiting interspersed with symptom free periods. Common triggers of cyclic vomiting include noxious stress, excitement, fatigue and menstrual period. Here, we report a case of cyclic vomiting syndrome in adult patient characterized by stereotypical vomiting attack, occurring in every menstruation period. Recurrent vomiting episodes began 6 years ago and we treated this patient with subcutaneous injection of goserelin, a gonadotropin-releasing hormone analogue (GnRHa) and oral estrogen. After 4 months of therapy, she was symptom free for the following 5 years, even with the resumed normal menstruation. Recurrence of vom - iting attack with same pattern occurred 1 month before readmission. Treatment with intravenous lorazepam aborted vomiting, but could not prevent recurrences of vomiting and epigastric pain. We treated the patient with GnRHa and oral estradiol again which effectively prevented recurrence of the symptoms.

A case of recurrent Kikuchi-Fujimoto disease with SLE / 대한내과학회지

Kikuchi-Fujimoto disease (KFD) is a rare self-limiting necrotizing lymphadenitis found mainly in young women. Patients typically present with lymphadenopathy and often with a high temperature. The etiology of the disease remains unknown, but various viral infection and autoimmune processes have been postulated to be the cause. One theory proposes that KFD may be a self-limiting form of systemic lupus erythematosus (SLE). This theory is strongly supported by the fact that microscopic features of KFD can be very similar to those found in lupus lymphadenitis. The diagnosis of KFD can precede, postdate or coincide with the diagnosis of SLE. No treatment is usually needed and relapse, although possible, is uncommon. Our case describes a young woman, originally diagnosed as having SLE, who subsequently developed recurrent KFD with axillary lymphadenopathy and fever.

A Case of Acute Leukoencephalopathy in a Patient with Systemic Lupus Erythematosus / 대한류마티스학회지

Up to 70% of patients with systemic lupus erythematosus (SLE) are afflicted with neurologic manifestations. However, there are only a few reports documenting acute leukoencephalopathy in SLE. We describe a 20-year-old woman who was recently diagnosed as SLE, suffering from headache, fever and arthritis. She developed an acute onset of consciousness disturbance with seizure followed by prolonged coma, which recovered completely after 1 month of steroid therapy. Her brain MRI showed diffuse high signal intensity in the periventricular and subcortical white matter on T2-weighted and FLAIR images, whereas cerebral cortex, basal ganglia, and thalamus were spared. Acute leukoencephalopathy may be recognized as a subtype of lupus involving the central nervous system.

A Case of Overlap Syndrome of Dermatomyositis and Sjogren's Syndrome associated with IgA Nephropathy / 대한류마티스학회지

An "overlap syndrome" is used to describe patients who have two or more well-defined connective tissue diseases such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), systemic sclerosis (SSc), and polymyositis. Their coexistence is defined clinically and often by specific serologic tests. We report a case of dermatomyositis associated with IgA nephropathy that had overlapping features of Sjogren's syndrome. This dermatomyositis and Sjogren's overlap is a rarely reported overlap syndrome worldwide.

A Case of Fetal Alcohol Syndrome with Secondary Amenorrhea / 대한내분비학회지

Alcohol ingestion during pregnancy can be damaging to embryonic and fetal development. A specific pattern of malformation, identified as Fetal alcohol syndrome, has been documented in 1~2 of every 1,000 live infant births Fetal alcohol syndrome is characterized by growth deficiency, facial abnormalities, cardiac defects, minor joint and limb abnormalities, as well as central nervous system dysfunction, including microcephaly, mental retardation and abnormal neurobehavioral development. However, there are few reports of fetal alcohol syndrome associated with hormonal abnormality or amenorrhea. Recently, a case of secondary amenorrhea, which developed in a 19-year-old woman with fetal alcohol syndrome, was experienced at our institute, but the exact cause of the amenorrhea was difficulty to find. Herein, this case is reported, with a review of the literature.
