PURPOSE: Moyamoya disease is a primary vascular disease characterized by stenosis that is followed by occlusion of the intracranial portion of the internal carotid artery and other vessels of the circle of Willis. Since there has not been any specific reports about clinical manifestation in children, we plan to study on clinical manifestation through these patients who have moyamoya disease. METHODS: We have reviewed our case of moyamoya disease in patients admitted to Yonsei University College of Medicine and analyzed their age & sex distribution as well as clinical manifestations, together with brain CT and angiographic findings. RESULTS: The results were as follows: 1) Fifty cases of moyamoya disease were encounted during a 10-year period. 2) The male to female ratio was 1:2.3 and mean age was 6.3 years old. 3) The most common chief complaint on admission was hemiparesis followed by convulsion. 4) 42 patients(84%) showed infarction on brain CT and only 5 patients(10%) showed hemorrhage. Most common lesion was frontal lobe. 5) Bilateral occlusion of the internal carotid arteries was most common site of lesions on cerebral angiography.

Nine-month-old female infant was seen with a 7-month history of a nodule on the right temporal scalp, which had gradually increased in size. Stroking of the lesion resulted in urtication and blistering and there were no other cutaneous lesions. The histology showed subepidermal bulla formation and a dense infiltration of mast cells in the papillary and reticular dermis. We present an infant with solitary mastocytoma on the scalp, a rare site.

Attention-deficit/hyperactivity disorder (ADHD) leads to functional decline in academic performance, interpersonal relationships, and development in school-aged children. Early diagnosis and appropriate intervention can significantly reduce the functional decline caused by ADHD. Currently, there is no established biological marker for ADHD. Some studies have suggested that various indicators from the quantitative electroencephalogram (QEEG) may be useful biological markers for the diagnosis of ADHD. Until the 2010s, theta/beta ratio (TBR) was a biomarker candidate for ADHD that consistently showed high diagnostic value. However, limitations of TBR have recently been reported. Studies have demonstrated that phase-amplitude coupling, especially theta phase-gamma amplitude coupling, are related to cognitive dysfunction and may assist in the diagnosis of ADHD. As yet, the underlying mechanism is not clearly established, and the clinical efficacy of these biomarkers needs to be proven through well-controlled studies. Based on the heterogeneous characteristics of ADHD, subgrouping through QEEG plays a key role in diagnosis and treatment planning. Sophisticated, welldesigned studies and meta-analyses are necessary to confirm these findings.

Heterotopic pregnancy is defined as coexistence of intrauterine and ectopic pregnancy. The reported incidence of heterotopic pregnancy, which is normally rare, is particularly high (1%) after IVF treatment. It is important to have a high index of suspicion for the occurrence of heterotopic pregnancies because only 40% to 84% of cases can be diagnosed with transvaginal ultrasound at the initial presentation. Edwards syndrome occurs in 8,000 newborns and the incidence is much higher in elderly gravidas. We report a case of heterotopic pregnancy following IVF-ET resulting in 16 weeks of intrauterine pregnancy with fetal Edwards syndrome, and tubal pregnancy with a brief review of literature.

OBJECTIVE: The aim of this study is to review 6 years' experience of peritoneal inclusion cysts at our hospital. METHODS: A retrospective study of 13 cases of peritoneal inclusion cysts between Jan. 1, 1996 and Dec. 31, 2001 was carried out and then clinical feature, radiologic finding, and treatment method were compared with previous reports. RESULTS: Most of patients were premenopausal. Chief complaints were lower abdominal pain or palpable abdominal mass, and so forth. The majority of patients had history of lapalotomy. Peritoneal inclusion cyst was diagnosed by ultrasonogrphy and CT. Most specific finding is that normal ovary is seen in the cysts. In the past, operation was the main treatment method. Recently sclerotherapy was introduced and available. CONCLUSION: Because peritoneal inclusion cyst is benign and uncommon disease, it had not been interesting part. So, preoperative diagnosis rate was low and surgical resection was main treatment method. Preoperative diagnosis rate has been higher after it's clinical feature and specific radiologic findings were reported. Recently, conservative treatment may substitute for operation.

Objective: Diagnosis of anxiety has relied primarily on self-report. This study aimed to investigate the neural correlates of anxiety with quantitative electroencephalography (qEEG) focusing on the state and trait anxiety defined according to the Research Domain Criteria framework existing across the differential diagnosis, rather than focusing on the diagnosis. Methods: A total of 41 participants who visited a psychiatric clinic underwent resting state EEG and completed the State-Trait Anxiety Inventory. The absolute power of six frequency bands were analyzed: delta (1–4 Hz), theta (4–8 Hz), alpha (8–10 Hz), fast alpha (10–13.5 Hz), beta (13.5–30 Hz), and gamma (30–80 Hz). Results: State anxiety scores were significantly negatively correlated with absolute gamma power in frontal (Fz, r=-0.484) and central (Cz, r=-0.523) regions, while trait anxiety scores were significantly negatively correlated with absolute gamma power in frontal (Fz, r= -0.523), central (Cz, r=-0.568), parietal (P7, r=-0.500; P8, r=-0.541), and occipital (O1, r=-0.510; O2, r=-0.480) regions. Conclusion The present study identified the significantly negative correlations between the anxiety level and gamma band power in fronto-central and posterior regions assessed at resting status. Further studies to confirm our findings and identify the neural correlates of anxiety are needed.

PURPOSE: The purpose of this study was to evaluate the usefulness of diffusion-weighted imaging (DWI) for the differential diagnosis of various intracranial cystic lesions. MATERIALS AND METHODS: This study included 19 patients (13 males, 6 females) with a mean age of 42.5 years. The final histopathological diagnoses for 14 patients were pyogenic brain abscess (n=3), glioblastoma (n=3), ependymoma (n=1), anaplastic astrocytoma (n=1), pilocytic astrocytoma (n=1), hemangioblastoma (n=2), arachnoid cyst (n=1), epidermoid (n=1) and schwannoma (n=1). The other cases of metastasis (n=4) and arachnoid cyst (n=2) were diagnosed on the basis of clinical, laboratory and imaging data. DWI imaging studies were performed with a 1.5 T MR system. A single shot spin echo EPI pulse sequence was applied. B values were set at 0 and 1000 sec/mm2. The apparent diffusion coefficient (ADC) were calculated from the ADC map of 10 different cystic brain lesions. Conventional MR imaging included T2WI, T1WI, FLAIR and contrast enhanced T1WI. We analyzed the location, nature, signal intensity on DWI, and the enhancement pattern of the lesions. RESULTS: All of the 3 cases of brain abscess, 1 of 4 cases of metastasis and 1 case of epidermoid showed hyperintensity on DWI. The mean ADC value of brain abscess (2 cases) was less than 1.15 (0.13x10-3 mm2/s). The mean ADC values of the other cystic lesions (8 cases) were variable, ranging from 2.840.66 to 3.100.16 (10-3 mm2/sec). CONCLUSION: DWI and ADC values were useful in the differential diagnosis of various intracranial cystic lesions, but some metastatic tumors may mimic a brain abscess on DWI. Therefore, a clinical correlation is mandatory.
