Delirium is a syndrome characterized by impairement of consciousness, disorientation, disturbance of sleep-wake cycle, memory impairement, disturbance of perception. It is induced by many causes, which are CNS diseases(head trauma, vascular disease, brain tumor, etc), medical diseases(metabolic disorder, endocrine disturbance, cardiovascular disease) and drugs(anticholinergics, anticonvulsant, antipsychotics, cimetidine etc). Transdermal scopolamine which is usually used to prevent motion sickness has anticholinergic property, and so it can induce delirium. The authors report two cases of delirium induced by transdermal scopolamine. The cases shared common characteristics which were as follows : 1. All of two patients were elderly women. 2. Delirium symptom was abruptly occurred during trip after attaching scopolamine patches. 3. Delirium symptom was rapidly improved within 2-3 days. It is important to educate for both users and managers about directions for transdermal scopolamine patch usage to prevent delirium. And careful history taking is needed to diagnose delirium induced by transdermal scopolamine accurately.

Neurofibromatosis is an autosomal dominant disorder caused by a mutation of a tumor supressor gene on the long arm of chromosome 17. There are two types of neurofibromatosis, and development of neurofibroma is one of clinical diagnostic criteria for neurofibromatosis. The clinical signs of neurofibromatosis include as skin lesions, bone deformities, and tumors involving central nervous system. About 25% of neurofibromatosis involves oral neurofibroma. Radiographically, oral neurofibroma is well-defined unilocular radiolucency, which involves mandibular canal, mandibular foramen and mental foramen. When a lesion is small and approachable, complete resection, including 1cm of marginal connective tissue, is feasible. However, there are studies reporting that the recurrence rate after surgical resection is high and frequent recurrence may even increase the risk of malignant transformation. This case reports a patient with neurofibromatosis type I, accompanying oral neurofibroma, who shows a favorable result after surgical resection of the oral lesion.

Hunter syndrome (mucopolysaccharidosis type II, MPS II) is a X-linked lysosomal storage disease caused by a deficiency in the lysosomal enzyme, iduronate-2-sulfatase (IDS), leading to accumulation of glycosaminoglycans within lysosomes of many organs and tissues. Since the enzyme replacement therapy was approved and available in the treatment of MPS I, II, VI, early diagnosis and early therapy can bring the better prognosis of disease and the better quality of life in patients. We described a 2.5 year old child presented with frequent otitis media and developmental delay including speech impairment, who was diagnosed as Hunter syndrome with IDS NM_000202.5:c. 263G>A(p.Arg88His) mutation.

An accurate quantitative biomechanical evaluation for the spasticity caused by the disorder of central nervous system was made in this study. A sudden leg dropper was designed to generate objective testing environment at every trial. 3-dimensional motion analysis system(Elite. B.T.S. Italy) was used to measure kinematic data which were angle. and angular velocity of a lower limb. A program was developed to analyze the kinematic data of lower limb motion. and dynamic EMG data at the same time. To evaluate spasticity quantitatively. total 26 parameters including 14 parameters newly driven were analyzed, and statistical analysis were made for bilateral correlations. Results showed possibility to make accurate quantitative and objective evaluation for spasticity with various new parameters using new devices and program.

Intractable hiccups are those which persist for more than one month and can often occur in patients with disorders of the central nervous system, such as stroke, epilepsy, or brain tumor. An 80-year-old male patient undergoing conservative hemodialysis for diabetic nephropathy, recently developed paralysis and dysphagia due to central nervous system complications including stroke and epilepsy. He was admitted to the ◯◯ Oriental Medicine Hospital, and treated with herbal medicine (Gyulpijugyeo-tang, Jeonssiigong-san, and Ijin-tang) and electrical acupuncture for 30 days. No side effects were observed during hospitalization. The frequency and duration of hiccups were measured daily and found to reduce, and the effect persisted during his admission. The patient took no other nervous system drugs. In conclusion, Korean medicine like gyulpijugyeo-tang and acupuncture can be effective for patients with intractable hiccups who cannot use alternative drugs or treatment, because of other complications.

Background: Cognitive deficit by hypoxia and/or hypercapnia is one of neuropsychological impairments frequently observed in patients with chronic obstructive pulmonary disease (COPD). The degree of cognitive deficit is variable among patients with similar level of hypoxia and/or hypercapnia, although a cause of this individual difference is well not known. COPD can be divided into two characteristic clinical entities including predominant emphysema and predominant bronchitis. This study was designed to evaluate the individual difference in cognitive deficit respond to hypoxia and/or hypercapnia in patients with COPD. Method: Sixteen patients with COPD (9 emphysema-dominant and 7 bronchitis-dominant) participated in this study. On admission arterial blood gas analysis and trail-making B (TMB) test for the evaluation of cognitive function were done in all patients. Mean TMB scores and the correlations between TMB scores and arterial blood gases were compared between two clinical groups. Results: 1) Mean TMB scores and arterial blood gases between two clinical groups were not different. 2) There was a tendency to be higher TMB score in hypoxemia, acidemia, and hypercapnia. However these findings were not statistically significant. 3) In emphysema-dominant group, $PaCO_2$ was mostly well correlated with TMB score (r=0.693). 4) In bronchitis-dominant group, arterial pH was mostly well correlated with TMB score (r=-0.526). Conclusion: Our data suggest that the individual difference in cognitive deficit respond to hypoxia and/or hypercapnia in patients with COPD may be dependent on their clinical entities, and arterial blood gases mostly well correlated with cognitive function that may be different according to their clinical entities.

Alcohol is so-called "a magic bullet" affecting on the various organs and central and peripheral nervous systems and causes mental illness as well as physiological and psychological dependence. Also, alcohol problem is related with serious social problems including family violence, suicide, loss of job and crimes. Because alcohol use disorder is a common cause of consultation and liaison in general hospital, we could consider alcohol use disorder of one of psychosomatic disorder. Thus, I reviewed the prevalence, rate of consultation, and general consultant and treatment issues in treating patients with substance use disorder in a psychosomatic medicine.

This study was designed to determine whether cognitive impairment was evident in patients with SLE. Also, it aimed to examine the association of cognitive impairment with other clinical variables. The subjects consisted of 20 patients with mildly active SLE and 20 healthy controls. Methods : A total of 20 SLE patients and 20 normal controls completed a computerized neuropsychological test battery using Vienna Test System. These included Cognitrone test, Continuous attention test, Corsi block tapping test, Standard progressive matrices. Also, neuro-behavioral cognitive status examination was done. The symptom severity of depression was measured with Beck Depression Inventory, Hamilton Depression Rating Scale, and current medications were documented. Disease activity was rated using the SLE diasease activity index (SLEDAI). Results : SLE patients had poorer performance than normal controls on the tests of Cognitrone, attention, nonverbal IQ and memory, independent of age, education, disease activity, steroid use and depression status. Conclusion : Cognitive dysfunction was not uncommon in ambulatory SLE patients as measured by standardized neuropsychological tests. It seemed to occur independently of various clinical variables. These findings would suggest that cognitive dysfunction in SLE may be explained by reflecting subclinical central nervous system(CNS) involvement, rather than coexisting psychological distress due to chronic illness or side effect of medication.

Purpose: This study was to investigate the clinical manifestations of FTT in children. Methods: From March 1997 to July 1999, clinical observations were made on patients with FTT who had visited to Samsung Medical Center. Detailed histories and through physical examinations were taken, and when suspected organic FTT, basic laboratory studies were done. Results: Upon the review of medical records, we investigated the clinical manifestations of 74 children, aged 1 month and 13 year 1 month. The causes of FTT were composed of either physiologic (47.8%) or pathologic (52.2%) ones. Among the physiologic FTT, were there familial short stature (FSS, 14.5%), intrauterine growth retardation (IUGR, 14.5%), constitutional growth delay (CGD, 11.6%), idiosyncrasy and prematurity. Among pathologic causes, neurologic disorders (20%) are the most common causes of FTT, and then follow by GI (13.4%), allergic and infectious disorders in decreasing order. The data showed that average caloric intake in patients with FTT was 76,2% of recommended amount. FTT patients with CGD, IUGR, and idiosyncrasy had tendency to take small foods. The FTT children with prematurity, IUGR and pathologic FTT, were short and thin for their ages. However FTT children with CGD and FSS had tendency to be thin with relatively normal heights for their ages, in comparison with those of the children with prematurity, IUGR and pathologic FTT. Conclusion: The diagnosis of FTT was easily obtained with simple and through medical history, physical examination, and minimal laboratory tests. In this study, organic FTT was more prevalent than physiologic one. This results indicate that early intervention is mandatory, because children may develop significant long-term sequelae from nutritional deficiency.
