Exploration of the injured brachial plexus is very hard due to the close approximation with other vital structures and the anatomic complexity. It is essential to identify the exact level and type of traumatic brachial plexus injury (BPI) to decide the appropriate surgical approach for the injury and to infer the postoperative prognosis. However, it can be difficult to image the brachial plexus because of the anatomic properties. The purpose of this study is to analyze the diagnostic value of MRI according to various planes of the level and the type of the traumatic BPI. In sixty patients with traumatic BPI, whose diagnosis was confirmed by clinicopathological and surgical findings, the preoperative MRI films were reread retrospectively. Brachial plexus injuries were divided into two groups of preganglionic BPI and postganglionic BPI, and then postganglionic BPI was divided into 3 subgroups of Zone I, Zone II and Zone III by major adjacent structures such as scalenus anterior muscle and pectoralis minor muscle. The accuracy of MRI was investigated with the confirmed diagnosis on axial, sagittal and coronal planes. In preganglionic BPI, the accuracy of MRI was 96% on axial plane and it was statistically significant compared to sagittal and coronal planes. In postganglionic BPI, the accuracy of MRI was 100% on sagittal plane and 86% on coronal plane in Zone I, but it was not significant statistically. In Zone II and III the accuracy of MRI were 89% and 80% on sagittal plane, and 61% and 60% on coronal plane, but it was not significant statistically. In conclusion, the MRI can provide useful guidance to diagnose preganglionic and postganglionic BPI. Axial imaging is considered better for preganglionic lesion and sagittal imaging for postganglionic BPI, but it demands further study on larger number of subjects with traumatic RPI.

A clinical observation of the bladder and urethral injuries was made in the army hospital from Jan. to Dec 1968. The results were obtained as follow; 1. The bladder and urethral injuries were 2.3% of all patients treated in the hospital in the last year. 2 The bladder and urethral injuries were 23 cases of the automobile accidents, excluding 3 cases of expulsive injuries and 2 cases of falling accidents 3. The bladder and urethral injuries associated with fracture of pelvic bone were 32.1%, especially 80% in the pubic ramus fracture. 4. The incidence of urethral injury was higher than bladder injury. 5. The complications were urethral stricture (80%). impotence and etc.

The antepartum death of one fetus in twin pregnancy is a rare obstetric complcation. If one fetus in twin pregnancy died in uterus remote from term and another fetus did not, the dead fetus will be compressed between the uterine wall and the membrane of living fetus, becomes a fetus compressus or fetus papyraceous. The primary maternal threat when the fetuses undelivered is disseminated intravascular coagulation. Concern for the surviving fetus after death of its co-twin is balanced between the risks of preterm birth and those involving exposure to events in utero that may threaten its well-being. Recently we experienced a case of twin pregnancy complicated by the death of one fe- tus, we report this case with concerned literatures.

In order to assess the efficiency of Percoll gradient centrifugation(PGC) as a method of sperm selection, we have examined morphological characteristics of spermatozoa from 40 teratozoospermic patients attending the Infertility Clinic of Inchon Gil Gerneral Hospital. Patients were divided into three groups according to percentage normal morphology in the fresh sample : group A(n=5), < 5% normal morphology : group B(n=21), 5~14% normal morphology : and group C(n=14), > 14% normal morphology. Morphology slides were perpared using Diff-Quik staining techniques and evaulated by Kruger strict criteria, under oil immersion at a magnification of X 1000, specific defects, head, neck and tail were assesed individualy. The results were as follows. 1. Following PGC, sperm samples with enhanced morphology were recovered for all groups. 2. For group A, PGC did not select a sample with significantly improved morphological characteristics. 3. Usually, sperm defects affected by PGC was head and neck. No significant difference was found for tail abnormality. In conclusion, Percoll gradient centrifugation is an efficient sperm preparation technique when the semen sample exhibits teratozoospermia, especially head or neck abnormality. However, in sample with < 5% normal form or tail abnormality, There is not significant improvement following PGC.

Fluorescein angiography (FAG) has been widely used in the diagnostic evaluation of choroidal tumors. Indocyanine green angiography (ICGA), which permits better visualization of choroidal vasculature than FAG, has been recently introduced into clinical practice. FAG and ICGA of 13 patients with choroidal tumors were assessed. These included 4 patients with choroidal nevus,4 with malignant melanoma, 2 with metastatic choroidal tumor,and 3 with choroidal hemangioma. In choroidal nevus, ICGA showed persistent hypofluorescence with clear delineation of the lesion in the late phase. Characteristic fluorescein angiographic feature of choroidal melanoma was hyperfluorescence in the late phase. However, the fluorescence of melanoma varied from hypo-,to hyperfluores- cent in the late phase of the ICGA. In choroidal metastatic tumor, FAG showed the typical pinpoint hyperfluorescence in the early phase and the diffuse leakage with serous detachment in the late phase. ICGA showed the hypofluo- rescence throughout the whole phases. In choroidal hemangioma, FAG and ICGA showed complete dye filling of the hemangioma with more denser hyperfluorescence in the early phase than in the late phase. In all patients, the lesion was better defined on the ICGA than on the FAG. This study suggests that ICGA combined with FAG may be useful in differentiating various choroidal tumors.
