OBJECTIVES: Delirium is a disorder defined as a sudden disturbance in thinking, speaking, acting and sleep pattern due to altered level of consciousness and cognitive function. The objective of this study is to analyze characteristics and therapeutic methods of the delirious patients during the recent 5 years, and provide basic data for further studies and investigation regarding delirium in the occurrence and treatment. METHODS: We retrospectively reviewed medical records of 475 patients who were consulted for delirium in Kyunghee University Medical Center from January 2007 to December 2011. RESULTS: During the 5 years, among the 475 patients who were diagnosed as delirium, men were more common(61.7%). The most commonly consulted reason and cause were sleep disturbance(80.8%) and post-operational delirium(30.9%), respectively. The medication prescription percentage was 76.6% and was significantly increased year after year. Ratio of using antipsychotics were 76.4% among prescribed medication and the most frequently prescribed antipsychotic drug was quetiapine(46.8%). Other specialists commonly misdiagnosed delirium when the patient was previously diagnosed as dementia(6.8%). CONCLUSIONS: In our study, post-operational delirium was the most commonly referred reason and the percentage of medication prescription tended to increase. Patients with history of dementia were more easily misdiagnosed as diseases other than delirium. Our study suggests that we should evaluate symptoms, causes, reasons of consultation, management tendency of delirium. We should also closely observe changes in sleep patterns and establish the prevention strategies for post-operational delirium and therapeutic bases for pharmacotherapy.

The abnormalities in Hypothalamic-pituitary-adrenal(HPA) axis are associated with many psychiatric symptoms including depression. We present a report of a 71 year old man who was admitted to the psychiatric department presenting symptoms of headache, avolition, loss of energy, psychomotor retardation, poor appetite, insomnia, anxiety resulting from adrenal insufficiency and hypopituitarism. Hypothyroidism and electrolyte disturbance were managed and headache, insomnia, anxiety, GI symptoms were improved. But he remained in anergic state. After discharge, he was readmitted to infection department with high fever and drowsy mentality. Adrenal insufficiency was recognized and he was treated with corticosteroid replacement therapy. Finally his diagnosis was made as panhypopituitarism and overall symptoms were resolved. In this case, we showed how the atypical symptoms resulting from hypopituitarism develop and progress. Hypothyroidism, adrenal insufficiency, and growth hormone deficiency resulting secondarily from panhypopituitarism were associated with various nonspecific symptoms such as loss of energy, fatigue, insomnia, weight loss, decreased appetite etc. In clinical situation, differential diagnosis with depression is needed when clinicians were met a patient with these nonspecific symptoms. It is important that laboratory tests and differential diagnosis with endocrine diseases should be conducted, especially in geriatric patients with nonspecific symptoms like anergia, fatigue, poor appetite and so on.

PURPOSE: There were many studies on the distributions of the retinal ganglion cells(RGC) in the experimental model of the retinal ischemia. RGC was known to be more sensitive to the ischemic injury than the other types of the retinal cells. So, we would identify the changes of the retinal ganglion cell morphologies and distribution after the iatrogenic retinal ischemia induced by intraocular pressure(IOP) elevation. METHODS: Eight pigmented and six white rabbits were used and retinal ischemia was induced by increasing IOP higher than 120 mmHg for 60 minutes. Electroretinogram were recorded at 6 days or 13 days, and histologic findings were observed at 7 or 14 days. RESULTS: After 7 days, RGC densities decreased, cytoplasmic staining disappeared, and the intranuclear hyperpigmentation was noted. RGC densities decreased significantly at 14 days. In the vertical retinal section, some flattening of retinal ganglion cell layer and inner plexiform layer was observed. Changes in the cellular morphologies were prominent. CONCLUSIONS: It may be more appropriate to examine both the retinal whole-mount and the vertical tissue section for the estimatation of the changes of retinal ganglion cell layer in the pressure-induced retinal ischemia.

A total of 23 human fetal hearts from 18 to 40 weeks of gestation were provided for histologic and morphometric studies. The fetuses were the products of spontaneous or artificial abortions and were found to have no congential anomalies or associated lesions at autopsy. Maxima thickness of the left anterior, left lateral, left posterior, right anterior, right lateral, right posterior ventricular wall, and of the interventricular septal wall were measured and the left / right wall thickness ratio was calculated. The cross-sectional area of each ventricle parallel to the base of the heart at about 3-5mm below from the origin of the aorta was measured under drawing attachment-equipped light microscope with the application of point counting or cut-and-weigh method. Data were analyzed by the Anderson-ell ABSTAT dBASE ll statistical package program. The ventricular wall consisted of endocardium, myocardium and epicardium. The myocardium showed epithelial character by stratification of barrel-shaped myocardial cells, but the epithelial character progressively changed to as in adult myocardial tissue from the myocardial area close to the epicardium with increasing fetal age. However, any significant histologic difference between the left and the right ventricular wall at the same fetal age was not found. The growth pattern of both ventricular wall, the interventricular septal wall, and of the cross sectional area were linear (p<0.01). However, there was no significant difference in the wall thickness between the left and right ventricle at the same fetal age, and the left / right thickness ratio was nearly constant with increasing fetal age. The cross sectional area was greater in the right than in the left ventricle in the fetuses after 18 weeks of gestation (p<0.01), and there was no significant difference in the morphometric values between point counting and cut-and-weigh method (p>0.1).

The objectives of this study were to investigate the efficacy and dose-effect relationship for glycopyrrolate in the suppression of the oculocardiac reflex, and to compare glycopyrrolate with the reported equivalent dose of atropine. Glycopyrrolate 5 and 7.5ug/kg and atropine 10 and 15ug/kg were studied in 40 paediatric patients to assess more fully the dose of glycopyrrolate required for adequate prevention of the oculocardiac reflex. The results obtained were summarized as follows: 1) The increase in the mean heart rate 5 min after the test drug was statistically significant in all of the four groups. 2) Both drugs showed a dose-related response for reduction in slowing of heart rate after rectus muscle traction. 3) There is great individual variation in response to muscle traction within each group, no group being fully protected from marked slowing in heart rate. 4) The frequency of arrhythmias with low doses of both drugs was more than in high doses with both drugs.

Erythromelanosis follicularis faciei et coli is a pigmentary disorder of unknown cause originally described by Kitamura et al in 1960. We describe two cases of erythromelanosis follicularis faciei et colli occured in adolescence. Clinical features of these patients were consistent with the clinical changes described in previous cases having clinical triad of erythema, hyperpigmentation and follicular papules. This pigmentary disorder may not be an uncommon disease, however it might be neglected from the concern of the dermatologists.

Emphysematous cholecystitis is an uncommon condition which may mimic acute cholecystitis. But it differs from acute cholecystitis in its relatively greater frequency in men and diabetics and has graver prognosis. The condition is diagnosed by demonstration of air in lumen,wall of gallbladder and/or pericholecystic space using a variety of radiographic techniques: simple abdominal radiography, ultrasonography and CT scanning. One illustrative case is presented herein and the pertinent literature is reviewed.
