OBJECTIVES: The course of Alzheimer's disease is often complicated by psychiatric symptoms including depression, delusion and hallucination. And these psychiatric symptoms may be due to neuropathological changes of the disease itself. This study examined whether psychiatric symptoms in Alzheimer's disease are associated with cerebral perfusion using single photon emission computed tomography (SPECT). METHODS: Supratentorial transaxial perfusion measurements were obtained in frontal, anterior temporal, posterior temporoparietal and occipital cortical areas in both hemispheres, in a baseline population of 29 mild to moderately impaired AD patients. We interviewed all the patients and their primary caregivers to assess their current and past psychiatric functioning. To compare the SPECT findings, all the patients were divided into two groups by presence of depression, delusion, hallucination and illusion, of which symptoms were explored separately. RESULTS: The patients with hallucination had hypoperfusion of both the posterior temporoparietal and the occipital regions of interest, compared with scans of the patients without hallucination. And in other symptom profiles, there was no difference in SPECT findings between the patients with symptoms and without symptoms. CONCLUSION: Psychotic patients with Alzheimer's disease had a pattern of cerebral perfusion deficits, which is different from that of nonpsychotic patients. This finding suggests that specific patterns of cerebral dysfunction probably be related to the specific psychiatric symptoms in Alzheimer's disease.

Herpes zoster oticus (Ramsay Hunt syndrome) is characterized by facial nerve paralysis associated with vesticular eruptions and cochleovestibular symptoms. Many evidences have supported that it is caused by the reactivation of latent varicella-zoster virus in the geniculate ganglion. Recently we experienced a case 49-year-old man presented severe vertigo and a vesicular eruptions of auricle and external ear canal. It is an unusual variant of herpes zoster oticus that involves only vestibular nerve without facial nerve palsy and hearing loss. We believe this case results from reactivation of latent varicella zoster virus in the vestibular ganglion and report with a review of literatures.

In recent trends of popularized sports and increased industrial hazards, we need the therapeutic modality in clinical setting, as a training and testing device for sports practicians, and as a method for scientific examination of post-operative status of muscles and joint function for orthopedist. Isokinetic exercise with Cybex II overcomes many biomechanical factors and can be used for fatigued patients by control of resistance. We examined internal rotator and external rotator muscle force of the shoulder joint, in order to acquire the isokinetic normative data of the shoulder for clinical use. The result were as follows 1. Strength and Power decreased as ages getting old, and there was significantdiminishbetween5th decade and 6th decade. 2. Power endurance did not decrease significantly as ages getting old. 3. The mean values of strength and power in internal rotator were higher than external rotator.

Accompanying to the development of the knowledgment of mechanism and pathology of recurrent dislocation of the shoulder, accurate diagnostic tools to detect that pathology have been developed. During the period from May 1990 to May 1992, we treated 28 cases of recurrent anterior dislocation of the shoulder. Twenty-eight cases were examined with C.T. arthrography before the operation. Among the 28 cases, we identified the Bankart lesion in 20 cases by C.T. arthrography, and in 21 cases intraoperatively. We concluded that the C.T. arthrography is an accurate method for confirming the clinical diagnosis of recurrent dislocation of the shoulder and to be helpful in detecting the Bankart lesion and its severity or pathologic findings.

PURPOSE: Sexual dysfunction has been reported to be frequent in patients with acute myocardial infarction. One aim was to correlates the erectile function with the severity of coronary arterial disease in the acute myocardial infarction patients. MATERIALS AND METHODS: A total of 57 men, median age 55.7 years (range 29 to 81), with acute myocardial infarction who had received coronary angiography were evaluated about their erectile function with 15-item questionnaire, the International Index of Erectile Function (IIEF). History of vascular risk factors such as smoking, diabetes mellitus, and hypercholesterolemia were obtained. We compared the erectile function score to the number of occluded coronary vessels or patients age. RESULTS: One coronary vessel was involves in 16 patients (28.1%), more than 2 coronary vessels were involved in 25 patients (43,9%) while 16 patients (28.1%) showed free of occlusion. Seventy-four percent of patients claimed abnormal erectile function, mild erectile dysfunction in 19 patients (33.3%), moderate in 9 patients (15.8%), severe in 14 patients (24.6%). Erectile function score decreased significantly according to increasing in the number of coronary vessels involved (p<0.05) and in patients age (p<0.01). CONCLUSIONS: There was a significant correlation between erectile function and the severity of the coronary arterial disease in acute myocardial infarction patients. The age of patients also had a negative effects on the erectile function.

Estriol excreation was studied in 216 normal and 61 pathologic pregnancies. The 95% fiducial limits of the normal excretion of estriol, within which 95% out of 100 future determinations in normal pregnancies are expected to fall, were established. The estriol curve in normal pregnancy in this study agrees well in its general shape with those presented by previous investigators who used different chemical methods of determination. The estriol values in pathologic pregnancies with preeclampsia. intrauterine fetal death and antepartum hemorrage have been analyzed. The clinical significance of estriol determinations during pregnancy was discussed.

The field of artificial intelligence (AI) is rapidly advancing, and AI models are increasingly applied in the medical field, especially in medical imaging, pathology, natural language processing, and biosignal analysis. On the basis of these advances, telemedicine, which allows people to receive medical services outside of hospitals or clinics, is also developing in many countries. The mechanisms of deep learning used in medical AI include convolutional neural networks, residual neural networks, and generative adversarial networks. Herein, we investigate the possibility of using these AI methods in the field of craniofacial surgery, with potential applications including craniofacial trauma, congenital anomalies, and cosmetic surgery.
