Pneumothorax*

Spontaneous testicular hemorrhagic necrosis is a rare disease usually associated with testicular torsion. Partially involved and suspicious testis tumor cases are also defined from orchiectomy specimens. Herein, a spontaneous hemorrhagic necrosis, without any testicular torsion, but with involvement of the whole testicle and epididymis, is reported. A 21 year old patient, who presented with a painless left testicular enlargement of several days duration was believed, based on physical examination, ultrasonography and elevation of serum LDH, to have a testicular tumor. Diagnosis was made only after radical orchiectomy and histopathological examination.

The relationship between the intestinal histopathology and number and position of intraepithelial lymphocytes (IEL) was observed chronologically in the small intestine of rats experimentally infected with Metagonimus yokogawai. Fifteen Sprague-Dawley rats were orally infected each with 3,000 metacecariae, and 3 were kept uninfected for controls. Three rats each were sacrificed on the day 5, 10, 15, 24 and 70 post-infection (PI) and samples of the small intestine, 5 cm, 10 cm, 20 cm and 70 cm posterior to the pylorus were taken. The samples were processed routinely and stained with Giemsa. The intestinal histopathology was severe during the day 5-15 PI and characterized by villous atrophy, crypt hyperplasia, and decrease of villus/crypt height ratio. After the day 24 PI, the intestinal lesions showed some tendency of recovery. The number of IEL increased at the early stage of infection, but decreased thereafter to a lower level than that of controls, with progression of the pathological changes. Then, the IEL number began to increase again after the day 24 PI. In control rats, the great majority of the IEL were located at the basal region of the epithelium. During the early stage of infection, however, a considerable proportion of IEL was found to have moved to the intermediate or apical region of the epithelium. From the above results, it is suggested that the change of IEL number and position during the course of M. yokogawai infection should be closely related to the progression and recovery of the intestinal histopathology.

PURPOSE: To recanalize the occlusive lesion of superficial femoral artery at origin site by retrograde approach via popliteal artery. MATERIALS AND METHODS: 15 patients, who were poor surgical candidates due to coronary artery disease and who had severe occlusive lesion of superficial femoral artery close to its origin with good distal runoffs to popliteal artery, were selected. Patients were all~men and range of age were from 53 years to 66 years (mean age:63 years). Range of lesion length were from 15cm to 30cm (mean length:22.4cm). Localization of popliteal artery was done with Doppler stethoscope or "road-map" DSA. The method of recanalization were transluminal endarterectomy catheter (TEC), TEC and angioplasty, thrombolysoangioplasty (TLA). RESULT: Retrograde puncture of popliteal artery were done in 15 patients successfully. TEC & PTA was performed in 9 patients, TEC only in 2 patients, and TLA & PTA in 2 patients. During the follow-up period of 5 months to 2 years reocclusion did not occurr in 10 patients except for 1 patient with poor cardiac output in whom it occured 1 day later. Remained 4 patients were lost in follow up. Any neurologic or vascular complication did not occur. CONCLUSION: Retrograde approach of superficial fernoral artery via popliteal artery in patients with difficult vascular intervention by common method provides a useful, alternative recanalization method.

Acute necrotizing encephalopathy is a recently established disease entity, proposed by Mizuguchi et al in 1995, that shows a characteristic symmetric and multifocal involvement of both thalamus, brainstem tegmentum, cerebral periventricular white matter, and cerebellar medulla. It is known to be prevalent in Japan and other Far Ease countries. The etiology of the acute necrotizing encephalopathy remains unknown. The typical course of acute necrotizing encephalopathy is the development of the irreversible neurologic symptoms related to brain lesions. The diagnosis can be made on the basis of the combination of a typical clinical profile and characteristic radiologic findings. We experienced a first case of acute necrotizing encephalopathy in a 9 month old boy in Korea. We report this case with the brief review of related literatures.
