1.A Case of Transcatheter Coil Embolization of Diffuse Pulmonary Arteriovenous Malformation.
Journal of the Korean Pediatric Society 2001;44(9):1036-1040
This is a case report of multiple coil embolization for the diffuse pulmonary arteriovenous malformations(PAVM). PAVMs are direct communications between pulmonary arteries and pulmonary veins, resulting in an anatomic right-to-left shunt that may cause paradoxical embolization to may occur, resulting in neurologic complications such as stroke or cerebral abscess. The treatment of choice for solitary PAVMs was limited to surgical resection or ligation of the PAVM but, multiple PAVMs present a difficult management problem, since surgical resection is not feasible in most instances. The coil embolization is a safe and effective treatment of multiple PAVMs. Our exprience was of a 5-year-old boy who had cyanosis and clubbing of his finger, and was diagnosed with multiple PAVMs by chest CT and pulmonary angiography. The coil embolization was peformed, thirteen vessels were successfully occluded and no complication in placement of coils occured. Embolization therapy should be performed in all cases of PAVMs to prevent neurologic complications.

PURPOSE: The purpose of this study was to evaluate the morphologic changes of the injured hepatic acini following ligation of common bile duct and to investigate the pathophysiologic process of hepatic failure and biliary liver cirrhosis in the extrahepatic cholestasis. MATERIALS AND METHODS: The common bile ducts of 18 rabbits were ligated partially. The rabbits were killed and selective microangiography was carried out with infusion of barium suspension via portal vein 4 to 24 weeks after ligation. Selective microangiography was also carried out in two normal rabbits. The microangiographic findings were evaluated and correlated with histopathologic features. RESULTS: The sinusolds of the liver acinus showed distortion, varying degrees of luminal widening, and irregularities in architecture. Terminal branches of the portal vein (TPV) showed increased number of branches, luminal narrowing, tortuosity, distortion, and beaded appearance. Peribiliary plexi were found as thin curvilinear, barium-filled structures along the wall of the dilated bile duct. The microangiographic findings were well correlated with histopathologic findings. The grades of microangiographic and histopathologic findings were poorly correlated with the duration of the ligation of CBD. CONCLUSION: Changes in microvasculature of the liver acinus following partial ligation of common bile duct were demonstrated by microangiography. Although the microvascular changes were evoked secondary to the injury, they might have some active roles in the pathophysiologic process in the liver.

Clinical and Bacteriological studies were carried out on 57 cases of infants and children with shigellosis who were cared from January, 1976 to December, 1980 in our hospital. The results were as follows: 1. The age distribution revealed the range between 6 months and 5 years(85% of all) with sex ratio of 30(53%) of male and 27(47%) of female, 1.1:1. 2. The peak incidence was noted in summer, althought there were occurrence throughout the year, even in winter. 3. On bacteriological studies, Shigellan flexneri was isolated most frequenty(90%) and Shigella sonnei was the next(8.8%). 4. Only 8.3% of Shigella strains were resistant to ampicillin between 1976 and 1977 but resistance increased to 76.7% in 1980. Gentamicin and Kanamycin which are aminoglycosiides were quite effectived but their use was limited becauseof their nephrotoxicity. 5. The average duration from the onset to the clinical improvement including stool character in the 32 ampicillin treated patients was 3.6 days and in the 25 rifampin treated patients was 2.2 days. Rifampin was effective in eradicating the shigella stralins and stool cultures taken at 7th therapeutic day remained negative in all 25 rifampin treated patients but yielded growth of shigella strains in 13 ampicillin treated patients. There was no doubt that rfaimpin was superior to ampicillin for bacillary dysentry. 6. One of these 57 cases was expired and motality rate was 1.8%.

OBJECTIVE: The goal of this study was to examine the colposcopic findings underlying referred cytologic abnormalities classified according to the Bethesda system. Further determine the strength of correlations between the referral smear performed at colposcopy, and the histologic diagnosis. METHODS: The charts of 462 patients who had referred to our hospital due to abnormal cytology at another hospitals from Jan. 1997 to Dec. 2001 at Soonchunhyang University Chunan Hospital were retrospectively reviewed. According to the necessities, repeat Pap, colposcopy-guided biopsy and conization was done. Results were compared both with referral Pap. One way ANOVA and chi-square test were used for statistical analysis. RESULTS: The results were as follows. 1. Mean age of the patients was 46.3 +/- 3.7 years. 2. Mean interval between referral smear and repeat smear or colposcopy was 3-82 days. 3. The agreement between referral and repeat Pap smears was 48.4%, no AGUS smears were conformed by repeat cytology and abnormal referral smears reverted to negative in 36.7%: 28.6% for the women with ASCUS, 50% with AGUS, 60% with LSIL, 36.4% with HSIL, and 13% with cancer. 4. The likelihood of a negative colposcopy guided biopsy of referral Pap smears was 14.3% for the women with ASCUS, 50% with AGUS, 25% with LSIL, 15.4% with HSIL, and 0% with cancer and more severe lesion than LSIL was found in 71.4% with ASCUS, 100% with AGUS, 68.8% with LSIL, 84.6% with HSIL, 100% with cancer. 5. The likelihood of a negative colposcopy guided biopsy of repeat Pap smears was 9.1% for the women with ASCUS, 50% with LSIL, 9.5% with HSIL, and 0% with cancer and more severe lesion than LSIL was found in 90.9% with ASCUS, 50% with LSIL, 90.5 with HSIL, 100% with cancer. 6. The likelihood of a negative conization of referral Pap smears was 12.5% for the women with ASCUS, 33.3% with AGUS, 0% with LSIL, 16.4% with HSIL, and 0% with cancer and more severe lesion than LSIL was found in 87.5% with ASCUS, 66.6% with AGUS, 100% with LSIL, 83.6% with HSIL, 100% with cancer. CONCLUSION: The agreement of referral smears with colposcopic biopsy and conization was 54.3% and 51.9%, respectively. Since the cytology classified according to the Bethesda system does not accurately predict histologic diagnosis, cytologic findings should not be used to determine treatment. Further we should use other methods as colposcopy, punch biopsy and conization to determine treatment.

OBJECTIVE: The objective of this study was to investigate the morphologic characteristics between the vertebral body and the regions of the cervical and thoracic spinal cords where each rootlets branch out. METHODS: Sixteen adult cadavers (12 males and 4 females) with a mean age of 57.9 (range of 33 to 70 years old) were used in this study. The anatomical relationship between the exit points of the nerve roots from the posterior root entry zone at each spinal cord segment and their corresponding relevant vertebral bodies were also analyzed. RESULTS: Vertical span of the posterior root entry zone between the upper and lower rootlet originating from each spinal segment ranged from 10-12 mm. The lengths of the rootlets from their point of origin at the spinal cord to their entrance into the intervertebral foramen were 5.9 mm at the third cervical nerve root and increased to 14.5 mm at the eighth cervical nerve root. At the lower segments of the nerve roots (T3 to T12), the posterior root entry zone of the relevant nerve roots had a corresponding anatomical relationship with the vertebral body that is two segments above. The posterior root entry zones of the sixth (94%) and seventh (81%) cervical nerve roots were located at a vertebral body a segment above from relevant segment. CONCLUSION: Through these investigations, a more accurate diagnosis, the establishment of a better therapeutic plan, and a decrease in surgical complications can be expected when pathologic lesions occur in the spinal cord or vertebral body.

An anomalous systemic arterial supply to the normal basal segments of the left lower lobe without sequestration is a rare congenital anomaly. It differs from classical bronchopulmonary sequestration in that the involver lung retains a normal connection to the bronchial tree, although some place this entity exists within the broad framework of pulmonary sequestration. We experienced a case of a woman who presented with a nodular lesion on a chest X-ray. Contrast-enhanced CT diagnosed her as having an anomalous systemic arterial supply to the normal basal segments of the left lower lobe. This case is reported with a brief literature review.

To identify the corresponding cord segment for each root at the level of conus medullaris, a dissecting microscopic study was carried out on the spinal cord of 14 adult cadavers. We measured following contents:1) the longitudinal extent of the medullary segment of origin of each root:2) the distance from the lowest rootlet of the conus to the highest portion of the medullary segment of each root:3) the distance from the conus tip to the lowest portion of the medullary segment of each root:4) the morphological features of root-spinal cord juncton, intrathecal anastomoses, and others. We measured on the basis of the last rootlet ecause of no clear distinction between the conus and filum terminale. Our values showed considerable variation from one case to another. The average length of the whole lumbar and sacral segment was 50 mm and 30 mm, respectively. The S-1 root was the largest. Intrathecal intersegmental anastomoses were found in all cases examined, and usually consisted of small caliber rootlets connecting the spinal roots of adjacent segments. We emphasize the importance of microsurgical structure of conus medullaris when performing an operation of dorsal root entry zone or myelotomy for the relief or spasticity or intractable pain of lower extremities.

PURPOSE: To determine clinical outcome in cases of traumatic intraventricular hemorrhage(TIVH) according to the mechanisms and amount of hemorrhage seen on initial CT. MATERIALS AND METHODS: We retrospectively reviewed the initial CT findings of 61 patients with TIVH. The mechanisms of TIVH were analyzed on the basis of the following CT findings: Type I; large intracerebral hematoma extending to adjacent ventricle; Type II: hemorrhagic and/or non-hemorrhagic diffuse axonal injury in the thalamus and basal ganglia; Type III: multiple small hemorrhagic lesions in the septum pellucidum, fornix, corpus callosum, and periventricular region, which may be due to inner cerebral trauma, Type IV: evidence of hypoxic brain injury, and Type V: TIVH with contusion and small subdural or epidural hematomas. The amount of TIVH was classified according to the Graeb score. We analyzed these mechanisms on the basis of CT findings, and for prognosis, correlated these with clinical outcomes and the Glasgow coma score. RESULTS: Prognosis was good in types V and III and poor in type I and II(p=0.001). In patients with a Graeb score of 4 or less, the clinical outcome was better than in those with a Graeb score above 5(p=0.03). Patients with a lower initial Glasgow coma score had poor outcomes(p=0.001). CONCLUSION: The hemorrhage mechanism in patients with TIVH could be important for estimating clinical outcome, especially during the early phase. In patients with type V or III TIVH, clinical outcome was better than in those with type I or II.

A 59-year-old man was admitted because of progressive proximal muscle weakness over 4 months. Serum creatine kinase was markedly increased and electromyography revealed myopathic pattern. Muscle biopsy showed nonspecific myopathic changes. No inflammatory change was shown. Thyroid function tests revealed very low thyroxine and low triiodo-L-thyronine, whereas thyroid-stimulating hormone was greatly increased as well as serum anti-thyroglobulin and microsome antibodies. The patient had hypothyroid myopathy due to Hashimoto's thyroiditis, which improved with L-thyroxine replacement.
