Pars interarticularis fracture is a common finding in young soccer players with low back pain. Spondylolysis in young adults involves a defect of the pars interarticularis, occurring as a result of repeated hyperextension and rotation. Here, we describe the case of a 26-year-old male elite soccer player who was diagnosed with L3 spondylolysis 2 years previously. He visited Incheon Himchan Hospital again because of low back pain. Radiographs showed consecutive spondylolysis at the L3 and L4 levels. Physicians should be aware that repeated performance of athletic movements, such as those during soccer, might lead to consecutive levels of spondylolysis.

Objective: We evaluated the protective effect of dexamethasone (DX) administration on brain damage produced in a perinatal model of cerebral hypoxia-ischemia in the rat. Since hyperglycemia has been shown to reduce hypoxic-ischemic brain injury (HI) in immature tar, we investigated the role of glucocorticoid-induced hyperglycemia in the neuroprotective mechanism of DX. Methods: Hypoxic-ischemic brain injury in 7-day-old rats was induced by right common carotid artery occlusion and 2 hours of 8% oxygen. Pups received 3 doses of DX (0.5mg/kg/d intraperitoneally) 48 hours, 24 hours and immediately before HI (Dx1)(n=12), a single dose of DX 24 hours(DX2)(n=16), 3 hours (DX3)(N=10)or immediately before HI (DX4)(n=14), a single dose of DX immediately after HI (DX5) (n=9), 3 doses of DX immediately, 24 hours and 48 hours after HI (DX6) (n=14) and a single dose of DX 24 hours before HI with insulin (0.5U/kg, subcutaneously, 1.5 hours before HI)(IN)(n=8). Control pups (n=15) received a single dose of normal saline 24 hours before HI. Blood glucose was estimated before hypoxia, 1 hour and 2 hours after hypoxia using glucometer in DX 1~4. IN and control rats. Pups were killed at 14 days of age for determination of mortality during HI, gross cerebral infarction and right cerebral hemisphere atrophy. We measured the diameter of each cerebral hemisphere and cortical thickness from a coronal section at the dorsal hippocampus level, and expressed the % atrophy from the change in the right vs left hemisphere diameter. Results: The mortality that occurred during and after HI was similar in all groups. The incidence of gross cerebral infarction was 0.0%, 0.0%, 75.0%, 83.3%, 87.5%, and 90.0% in DX 1~6, respectively, 0.0%in IN, and 100.0% in control group. There was a significant difference (p<0.001)in the incidence of gross cerebral infarction of DX1, DX2, IN vs control group. The mean % atrophy was 5.4 +/- 2.2, 4.9 +/- 1.8, 21.7 +/- 8.1, 29.7 +/- 5.0, 37.4 +/- 5.5, 33.4 +/- 9.3 in DX 1~6, respectively, 1.5 +/- 1.1 in IN, and 29.1 +/- 3.4 (mean+/-SEM) in control group. There was a significant difference in % atrophy of DX1, DX2, IN vs control group. Before hypoxia, there was no significant difference in blood glucose between saline, all DX, and DX with insulin treated groups. But after hypoxia, pups in DX1 and Dx2 were more hyperglycemic compared to DX 3~4, IN, or saline treated groups. Conclusions: Dexamethasone administration in the neonatal period protects the brain during the subsequent periods of hypoxia-ischemia in rats and glucocorticoid-induced hyperglycemia does not explain the neuroprotective effects dexamethasone.

OBJECTIVE: The authors present eight cases of immediate post-operative epidural hematomas(EDHs) adjacent to the craniotomy site, describe clinical details of them, and discuss their pathogenesis. METHODS: Medical records of eight cases were retrospectively reviewed and their clinical data, operation records, and radiological findings analyzed. Any risk factors of the EDHs were searched. RESULTS: In 5 of 8 cases, adjacent EDHs developed after craniotomies for the surgical removal of brain tumors. Three cases of adjacent EDHs developed after a pterional approach and neck clipping of a ruptured anterior communicating artery aneurysm, a ventriculoperitoneal shunt, and a craniotomy for a post-traumatic EDH, respectively. In all eight cases, brain computed tomography (CT) scans checked immediately or a few hours after the surgery, revealed large EDHs adjacent to the previous craniotomy site, but there was no EDH beneath the previous craniotomy flap. After emergent surgical removal of the EDHs, 7 cases demonstrated good clinical outcomes, with one case yielding a poor result. CONCLUSION: Rapid drainage of a large volume of cerebrospinal fluid or intra-operative severe brain collapse may separate the dura from the calvarium and cause postoperative EDH adjacent to the previous craniotomy site. A high-pressure suction drain left in the epidural space may contribute to the pathogenesis. After the craniotomy for brain tumors or intracranial aneurysms, when remarkable brain collapse occurs, an immediate postoperative brain CT is mandatory to detect and adequately manage such unexpected events as adjacent EDHs.

OBJECTIVE: A 10-year retrospective lumboperitoneal(LP) shunt surgery was reviewed in order to verify the several prognostic factors including the etiology, the findings of brain computed tomography(CT) and/or magnetic resonance imaging(MRI), and the effect of lumbar drainage which have been implicated in the result of LP shunt. PATIENTS AND MEHTODS: A series of 32 patients who underwent LP shunt surgery between March 1988 and May 1998 for the management of communicating hydrocephalus was reviewed. RESULTS: The etiology of communicating hydrocephalus was subarachnoid hemorrhage(SAH) in 19 cases(59.4%), head trauma in 10 cases(31.2%), intracerebral hemorrhage in 2 cases(6.3%), meningitis in 1 case(3.1%), tumor in 1 case(3.1%), and idiopathic in 2 cases(6.3%). The mean follow-up period was 1.2 years(range, 2 week to 8.5 year). Among them, twenty four patients(75%) were clinically improved after shunt operation. The result of LP shunt was not related to the etiologies and many findings of brain CT/MRI such as ventricular index, Evan's index, periventricular low density, obliteration of cerebral sulci and cortical atrophy. However, the result of LP shunt was significantly related to the effect of preoperative lumbar drainage(p=0.0184). CONCLUSION: This result suggests that the effect of preoperative lumbar drainage has a significant role in predicting the result of LP shunt in patients with communicating hydrocephalus.

Several prognostic factors have been implicated in survival prolongation in patients with metastatic brain tumors. Among these, surgery has been regarded as very significant one with respect to life prolongation and improving the quality of survival in such patients. From August 1982 through July 1996, a series of 31 patients with metastatic brain tumors among 785 patients with operated brain tumors, whose medical records, X-rays and follow-ups were avilable, was studied retrospectively to evaluate the beneficial effects of surgery. Despite the limitations inherent to the retrospective study and limited number of patients, we divided these patients into two groups to find out any statistical differences in terms of survival and quality of survival among them: 1) Conservative group(8 nonoperated patients: 5 patients with biopsy or partial resection): 13, and 2) Surgical treatment group(17 totally resected patients: one patient with subtotal resection): 18. The quality of survival was assessed by Karnofsky performance(KP) scale before and after each treatment. The survival of the patients in the surgical treatment group was longer than the conservative treatment group(14.5 months/10 months), but this was not statistically significant(p value: 0.3305). However, improvement of quality of survival, in terms of KP scale, was significantly higher in the surgical treatment group(p value: 0.0027). Although confounded by the lack of controlled, randomized study and limitations of retrospective study, aggressive surgery can be regarded to have a significant role in improving the quality of survival in patients with metastatic brain tumors.

OBJECTIVE: The purpose of this study is to characterize the distribution of posterior inferior cerebellar artery (PICA) aneurysm, the computed tomography (CT) patterns of hemorrhage, and the clinical presentation thereof. METHODS: We reviewed the records 1050 patients with intracranial aneurysms treated at our institution between January 1999 and November 2003. Upon clinical review of radiological data and postoperative reports, we found 20 patients with PICA aneurysms. RESULTS: The incidence of PICA aneurysms was 1.9% of all intracranial aneurysms. The location of PICA aneurysms varied. Of the 20 PICA aneurysm cases, ruptured aneurysms accounted for 18 cases. Review of only these ruptured cases resulted in the following observations : Subarachnoid hemorrhage (SAH) was presented in 94.4% of cases. Isolated infratentorial and supratentorial SAH was present in 7 cases (38.9%) and 2 cases (11.1%), respectively. SAH involving the infratentorial and supratentorial region was present in 8 cases (44.5%). Intraventricular hemorrhage (IVH) with or without associated SAH was seen in 77.8% of cases, whereas isolated IVH was seen in only one case. Perimedullary large hematoma was present in 50% of cases, while the hematoma was consistently thicker on the aneurysm side. Hydrochephalus was present in 16 cases (88.9%). Although patients' postoperative outcomes were excellent or good in 70% of the above cases, initial angiograms failed to reveal ruptured PICA aneurysms in 3 cases. CONCLUSION: PICA aneurysm is rare in most aneurysm cases. However, awareness of a possibility of PICA aneurysm and its features are still nonetheless important. IVH and hydrocephalus are commonly presented with a ruptured PICA aneurysm and complete vertebral angiography is a required to recognize this condition.

Dieulafoy lesion is an uncommon cause of gastrointestinal bleeding, reported to be only 2% of acute or chronic upper gastrointestinal bleeding episodes. Bleeding occurs from a small mucosal erosion involving an unusually large submucosal artery in an otherwise normal mucosa. It is associated with massive, life threatening hemorrhage and is difficult to diagnosis. In most cases the lesion is encountered in the proximal stomach, antrum, duodenum, colon and rectum. In particular, extragastric Dieulafoy lesion is an extremely rare source of intestinal bleeding. In Korea, no case of bleeding from a Dieulafoy lesion of the small intestine has been previously reported. We experienced one case of bleeding from a jejunal Dieulafoy lesion, which was confirmed by the pathologic examination of the resected specimen, and report here.
