Grice extra-articular subtalar arthrodesis has been performed as either a temporizing or a definite procedure in young children to correct the dynamic hindfoot valgus deformity without affecting subsequent growth of the foot. Fifty eight extra-articular subtalar arthrodesis in thirty patients, performed at Seoul National University Children's Hospital from setpember 1985 to June 1989, were retrospectively reviewed to evaluate the clinical and radiographic results. There were 52 valgus feet in 26 patients and 6 varus feet in 4 patients secondary to cerebral palsy, meningomyelocele, congenital snomalies, and other neuromuscular diseases. In many instances, additional tendon surgeries were also required to correct deformities or achieve the muscle balance. The review consisted of personal interview, physical examination, and radiological assessment. On physical examination, preoperative hindfoot valgus deformty(mean: 14.3°clinically) was well corrected, postoperative hindfoot valgus ranging from neutral to valgus 5°clinically in 35 of 52 cases(67.3%). Correction of the lateral talocalcaneal angle on standing lateral radiographic view averaged 8.5 degrees(from 57.3 degrees preoperatively to 37.6 degrees postoperatively). In valgus feet, there were 3 cases with mild pain around the ankle joint. There were 5 cases of graft resorption and 2 cases of nonunion. Graft failure was more frequent when the proximal end of the graft was directed anterior to the weight bearing axis. With original Grice subtalar arthrodesis, satisfactory results were obtained in 34 of 52(65.4%) hindfoot valgus feet. In 6 varus feet, there were 1 undercorrection and 2 recurrence of varus deformity. We re-emphasize the importance of strict operative technique to obtain satisfactory results. We also believe that Grice procedure may be used for the correction of subtalar instability in selected cases of varus foot before muscle baancing procedures.

BACKGROUND: The authors have developed a Digital image chart(DIC) and digital Radiotherapy Record System (DRRS). We have evaluated the DIC and DRRS for reliability, usefulness, ease of use, and efficiency. METHOD AND MATERIALS: The basic design o f the DIC and DRRS was to build an digital image database of radiation therapy patient records for a more efficient and timely flow of critical image in formation throughout the department. This system is a subunit of comprehensive radiation oncology managemert system (C-ROMS) and composed of a picture archiving and communication system (PACS), radiotherapy information database, and a radiotherapy imaging database. The DIC and DRRS were programmed using Delphi under a Windows 95 environment and is capable of displaying the digital images of patients identification photos, simulation films, radiotherapy setup, diagnostic radiology image... Gross lesion photos, and radiotherapy planning isodose charts with beam arrangements. Twenty-three clients in the department are connected by Ethernet (10 Mbps) to the central image server (Sun Ultra-sparc 1 workstation). RESULTS: From the introduction of this system in February 1998 through December 1999, we have accumulated a total of 15,732 individual images for 2,556 patients. We can organize radiation therapy in; paperless environment in 120 patients with breast cancer. Using this system, we have succeeded in the prompt, accurate, and simultaneous access to patient care information from multiple locations throughout the department. This coordination has resulted in improved operational efficiency within the department. CONCLUSION: The authors believe that the DIC and DRRS has contributed to the improvement of radiation oncology department efficacy as well as to time and resource savings by providing necessary visual information throughout the department conveniently and simultaneously. As a result, we can also achieve the paperless and filmless practice of radiation oncology with this system.

OBJECTIVE: The objective of this study is to examine the effects of cranioplasty on the cerebral hemodynamics and cardiac function. METHODS: Twenty seven patients who had undergone cranioplasty were included in this study. Arterial blood flow velocities were assessed by transcranial doppler ultrasonography and the cerebral blood flow(CBF) measurements by perfusion computed tomography. Cardiac functions were evaluated using the echocar-diogram. RESULTS: The blood flow velocity on the cranioplasty side was decreased from 50.5+/-15.4cm/sec to 38.1+/-13.9cm/sec at the middle cerebral artery(MCA) and from 33.1+/-8.3cm/sec to 26.4+/-6.6cm/sec at the internal carotid artery(ICA)(p<0.05). On the opposite side, it was decreased from 61.9+/-15.7cm/sec to 48.7+/-16.9cm/ sec at the MCA and from 31.8+/-7.3cm/sec to 24.5+/-7.1cm/sec at the ICA(p<0.05). The evaluation of cardiac functions revealed that the stroke volume was increased from 64.7+/-18.3ml/beat to 73.3+/-20.4ml/beat(p< 0.05) ; the heart rate was decreased from 91.4+/-14.7beat/min to 82.2+/-15.1beat/min(p<0.05). CBF was increased from 39.1+/-7.2ml/100g/min to 44.7+/-8.9ml/100g/min on the cranioplasty side(p<0.05). CONCLUSION: Cranioplasty can remove the atmospheric pressure on the brain and may decrease the blood flow velocity and increase the CBF as well as improve the cardiac function. The authors insist that a skull defect should be corrected as quickly as possible after neurological stabilization of patients.

Drug-induced immune hemolytic anemia (DIIHA) is a rare side effect of drugs. DIIHA may cause a systemic inflammatory response that results in acute multi-organ failure and death. Ceftizoxime belongs to the class of third generation cephalosporins, which are the most common drugs associated with DIIHA. Herein, we present a case of a 66-year-old man who developed fatal DIIHA after receiving a second dose of ceftizoxime. He was admitted to receive photodynamic therapy. He had a history of a single parenteral dose of ceftizoxime 3 months prior to admission. On the day of the procedure — shortly after the infusion of ceftizoxime — the patient's mental status was altered. The blood test results revealed hemolysis. Oliguric acute kidney injury developed, and continuous renal replacement therapy had to be applied. On the suspicion of DIIHA, the patient underwent plasmapheresis. Diagnosis was confirmed by a detection of drug-dependent antibody with immune complex formation. Although his hemolysis improved, his liver failure did not improve. He was eventually discharged to palliative care, and subsequently died.

OBJECTIVE: Massive intracerebral hemorrhage (ICH) and major infarction (MI) are devastating cerebral vascular diseases. Decompression craniectomy (DC) is a common treatment approach for these diseases and acceptable clinical results have been reported. Author experienced the postoperative intracranaial pressure (ICP) trend is somewhat different between the ICH and MI patients. In this study, we compare the ICP trend following DC and evaluate the clinical significance.METHODS: One hundred forty-three patients who underwent DC following massive ICH (81 cases) or MI (62 cases) were analyzed retrospectively. The mean age was 56.3±14.3 (median=57, male : female=89 : 54). DC was applied using consistent criteria in both diseases patients; Glasgow coma scale (GCS) score less than 8 and a midline shift more than 6 mm on brain computed tomography. In all patients, ventricular puncture was done before the DC and ICP trends were monitored during and after the surgery. Outcome comparisons included the ictus to operation time (OP-time), postoperative ICP trend, favorable outcomes and mortality.RESULTS: Initial GCS (p=0.364) and initial ventricular ICP (p=0.783) were similar among the ICH and MI patients. The postoperative ICP of ICH patients were drop rapidly and maintained within physiological range if greater than 80% of the hematoma was removed. While in MI patients, the postoperative ICP were not drop rapidly and maintained above the physiologic range (MI=18.8 vs. ICH=13.6 mmHg, p=0.000). The OP-times were faster in ICH patients (ICH=7.3 vs. MI=40.9 hours, p=0.000) and the mortality rate was higher in MI patients (MI=37.1% vs. ICH=17.3%, p=0.007).CONCLUSION: The results of this study suggest that if greater than 80% of the hematoma was removed in ICH patients, the postoperative ICP rarely over the physiologic range. But in MI patients, the postoperative ICP was above the physiologic range for several days after the DC. Authors propose that DC is no need for the massive ICH patient if a significant portion of their hematoma is removed. But DC might be essential to improve the MI patients’ outcome and timely treatment decision.

PURPOSE: To report a case of maculopathy after exposure to a high-voltage spark. CASE SUMMARY: A 40-year-old male patient visited our clinic complaining of visual disturbance in both eyes 1 day after exposure to a high voltage arc discharge. His best corrected visual acuity was 4/20 in both eyes. On fundus examination, a yellowish retinal scar was observed at the foveal area. The spectral domain optical coherence tomography (SD-OCT) showed inner segment/outer segment line disruption. The best corrected visual acuity was 4/20 in both eyes and SD-OCT showed a remaining inner segment/outer segment line disruption after 3 years. CONCLUSIONS: Maculopathy can result from exposure to a high voltage arc discharge exposure.

PURPOSE: In order to avoid functional disability that may be caused by radical excision or amputation in extremity soft tissue sarcomas, authors employed limb-conserving surgery together with extemal radiation therapy plus interstitial brachytherapy. MATERIALS AND METHODS: From June 1995 to Febrary 1997, 10 extremity soft tissue sarcoma patients were treated with limb-conserving surgery and external radiation therapy plus interstitial brachytherapy. In six patients, whose histologic diagnoses were made at the time of surgery, wide or marginal excision and interstitial brachytherapy was done 4 weeks before postoperative external radiation therapy. In four patients whose histologic confinnations were done before definitive treatment, preoperative external radiation therapy was given 4 weeks before surgery and interstitial brachytherapy. The types of surgery were wide excision in five patients, and marginal excision in five patients. Gross or microscopic residual was left at the surgical resection margins in four patients. The brachytherapy dose ranged from 17.5 Gy to 24 Gy and external beam radiation did from 40 Gy to 45 Gy. RESULTS: With the median follow-up duration of 21.5 months(range: 13 to 29 months); one local recurrence, and three new distant metastases were observed. There were three patients with wound complications attributable to the current treatment regimen. CONCLUSION: Satisfactory local tumor control may be achievable with limb-conserving surgery and external radiation therapy plus brachytherapy in patients with extremity soft tissue sarcomas, while more caution should be used to avoid wound problems.

A 42-year-old man with Erdheim-Chester disease (EC) is presented. This is the first case of this disease reported in Korea. The patient complained of knee pain and plain roentgenogram of the bilateral legs revealed diffusely increased density, coarsened trabecular pattern, and cortical thickening in the diaphysis, and metaphysis as well as epiphysis. Magnetic resonance imaging revealed that the lesions showed low signal intensity on T1-weighted images and heterogeneously low and high signal intensity on T2-weighted images. Histological examination of the biopsy specimen showed a xanthogranulomatous lesion consisting aggregations of foamy histiocytes and Touton-type giant cells. Immunohistochemical staining showed positive reaction to anti-S-100 and lysozyme in the cytoplasm of the giant cells.
