OBJECTIVES: Previous studies reported that attention-deficit hyperactivity disorder (ADHD) resulted from a deficit of selective attention and sustained attention. In this study, we assessed the result of methylphenidate-induced changes of the cerebral frontal executive functions in patients with ADHD. METHODS: The subjects in this study consisted of 16 ADHD patients whose age ranged from 7 to 12. We used ADHD Diagnostic System (ADS) for the attention improvement, and the Stroop Test for the executive function response to pharmacotherapy with MPH. RESULTS: After pharmacotherapy with methylphenidate for 12 weeks, the study group showed improvement in the clinical aspects through Clinical Global Impression-Severity, ADHD-rating scale and Inattention/Overactivity With Aggression Conner's Parents Rating Scale. In the ADS test, only in auditory task there was a decrease of both the response time and the standard deviation of the response time significantly. In the Stroop Test, there was a decrease in the word task, color task and color-word task significantly. CONCLUSION: Our results show that psychostimulant medication improves neuropsychological function, including the cerebral frontal executive function. This study implies that we have to consider the improvement of executive function, as well as attention when evaluating the efficacy of treatment.

Solitary choroidal tubercle is rare disease nowadays although it was frequently reported in the old literatures. It is characterized by indefinite yellowish-white round nodule in the posterior pole of the eyeball in young adults with inactive disease. It is sometimes protruded toward vitreous cavity with retinal necrosis, vitreous opacity and cyclitis. Authors experienced a case of solitary choroidal tubercle which had been misdiagnosed as a malignant melanoma. We confirmed it by pathologic findings.

The renin-angiotensin system plays an important role in renal growth and development. Exposure of the fetus or neonate to angiotensin converting enzyme (ACE) inhibitors increases mortality, growth retardation, and results in renal anomalies. This study was designed to investigate the effects of ACE inhibition in the neonatal rat on the expression of genes known to modulate renal cellular proliferation, cell interactions, and extracellular matrix. Newborn rat pups were treated with enalapril (30mg/ kg/day) or vehicle for 14 days, and kidneys were removed for determination of mRNA for transforming growth factor-beta 1 (TGF- B1) and prepro epidermal growth factor (EGF). Enalapril treatment resulted in 40Yo mortality by day 14 as well as reduced body and kidney weight (P<0.05 vs vehicle group). Also enalapril decreased renal TGF-Bl and EGF mRNA expression (P<0.05). These results indicate that ACE inhibition in the developing kidney reduces the renal expression of critical growth factors, which may account for renal growth impairment.

We experienced a case of vitamin B12 unresponsive methlymalonic acidemia in a 4 day old female, who had poor feeding, dehydration with metabolic acidosis, and hyperammonernia and died at 7 days of age. Diagnosis was made by gas chromatography and mass spectrometry, and this case is probably a methylmalonyl CoA mutase apoenzyme deficiency type.

Peripheral neuroepithelioma (PNE) of soft tissue is a malignant neuroectodermal tumor arising from peripheral (nonautonomic) nerve. It may occur in both children and adults, and are highly aggressive neoplasms that rapidly give rise to metastatic disease and death. We exprienced a case of peripheral neuroepithelioma of soft tissue in the upper arm in a 18-year-old female. Cytologic features revealed small round cells with scanty cytoplasm occurring both singly and in clusters. The clusters frequently tended to form Homer-Wright rosettes. The cells had a round to oval nucleus with fine chromatin and in- conspicuous nucleoli in a hemorrhagic background.
