A 77-year old man living in Kyunggi-Do, Korea was surgically treated at Seoul National University Hospital on April 1981, because of acute abdomen. At laparotomy, a 1.77m long adult Taenia saginata was found both in gallbladder and in common bile duct to cause acute gangrenous cholecystitis. The relevant literature were reviewed and possible mechanisms of the disease were discussed.

Experimental allergic encephalomyelitis (EAE) has been a well established animal model of postvaccinatal demyelinating diseases occurring in humans. Therefore elucidation of its pathogenesis would be very critical for the understanding of various human demyelinating diseases including multiple sclerosis. This study was performed to characterize the infiltrating cells in inflammatory sites and analyze the nature of the damage of blood brain barrier in experimental allergic encephalomyelitis. Experimental allergic encephalomyelitis was produced by administering homologous spinal cord homogenate together with complete Freund's adjuvant in guinea pigs. Immunostainings on guinea pig IgG, IgM, IgA and muramidase were performed by peroxidase-antiperoxidase or indirect immunofluorescent methods. The blood-brain barrier change was assessed by administering fluorescent Evans blue. Following results were made. In juvenile animals, both clinical findings and histopathologic changes were first noted by 3 weeks after injection and progressed during the whole experimental period. However, these findings were delayed in onset and low in incidence in adult animals. The clinical and pathologic changes started from the caudal portions and extended rostrally. The blood-brain barrier (BBB) was damaged and progressed starting also from the caudal portion of the spinal cord. The BBB changes were more severe in young animal than adult animals. Those changes preceded th histologic alterations. It is suggested that the BBB susceptibility is responsible for the caudal onset of histologic changes. Although the lesion has been thought to be induced by T-cell mediated hypersensitivity, infiltrating cells consisted mainly of muramidase positive histiocytes. A few immunoglobulin positive B cells or plasma cells could also be demonstrated in the lesion. The former usually infiltrated the parenchyme and the latter remained around the small or medium-sized vessels.

BACKGROUND: Fear of dental treatment is a very real problem for many people. Very young patients or children that are mentally or physically handicapped have various problems that preclude routine dental treatment in the office and require general anesthesia for extensive dental restoration. In America, outpatient operations are performed in thousands of dental offices annually, but there is no report about outpatient general anesthesia in Korea. METHOD: A review of forty children treated under outpatient general anesthesia for extensive dental treatment between 1994 and 1996 inclusive was carried out to assess the patient selection, anesthetic method, recovery time and complication. RESULTS: The mean age was 8.4 years, and twenty-five percent of the patients were autism. The length of the postoperative observation period before discharge was 3.2 hours, and postoperative fever was major complication. CONCLUSION: For extensive dental treatment in handicapped children, we suggest that outpatient general anesthesia can provide reasonably safe treatment, while reducing its expense and requiring less hospital bed space.

Scrub typhus (Tsutsugamushi disease)is an acute febrile systemic illness caused by Rickettsia tsutsugamushi that is transmitted to humans by the bite of larval-stage trombiculid mites (chiggers). The authors analyzed chest radiographic findings of scrub typhus in 160 patients in Ulsan area. One hundred and eight (67.5%) of160 patients showed abnormal findings which included lung lesions in 108 patients (67.5%), cardiomegaly in 37 patients (23.1%), lymphadenopathy in 25 patients (15.6%) and pleural effusion in 11 patients (6.9%). Among the lung lesions, interstitial patterns were seen in 107 patients (66.9%), mostly fine or medium reticulonodular, and air-space patterns in 14 patients(8.8%) and combined interstitial and air-space patterns in 13 patients (8.1%). Sixty-four patients(40%) had combined chest radiographic findings. The typical chest radiographic findings of scrub typhus would be helpful in evaluation of the causes of acute febrile illness that occur during late fall in the endemic area.

Various neurotransmitters have been proposed as possible mediators of penile erection. Especially, norepinephrine and serotonin might have a important role in sexual arousal and penile erection. And it could be hypothesized that the psychogenic impotence is associated with the depletion or imbalance of norepinephrine and serotonin from evidences such as the symptomatic manifestation of depression and the antidepressant-induced sexual dysfunction. The authors investigates the association of norepienphrine and serotonin with psychogenic impotence. The psychogenic impotent group(PIG) consisted of twenty-three patients with psychogenic impotence and the controlled group(CG) consisted of twenty-seven patients without psychogenic impotence. PIG had no organic cause accounting for their erectile dysfunction. The Beck Depression Inventory(BDI) and the State-Trait Anxiety Inventory(STAI) were applied to each subject to assess mood, state anxiety(SA) and trait anxiety(TA). Plasma norepinephrine level from systemic blood and 5-hydroxyindoleacetic acid(HIAA) levels from 24-hours urine were measured in each subject. The mean score of BDI of PIG was significantly higher than that of CG(p=0.015). PIG had a tendency of higher TA compared with CG(p=0.054). And also SA was higher in PIG, bud did not show significant difference(p=0.193). The level of norepinephrine was significantly lower in patient with psychogenic impotence(p=0.000). And the level of 24-hours urine 5-HIAA was lower in PIG but did not show significant difference(p=0.494). Although the authors did not exclude depressive disorders in PIG, the present findings suggest that psychogenic impotence might have higher depressive mood and trait anxiety, and be associated with the depletion of norepinephrine in systemic blood.
