Transfusion complications include ABO/Rh incompatibility, sepsis, febrile reaction, immunosuppression, and viral transmission. We experienced a case of anaphylactic reaction in a 40-year-old male scheduled for laminectomy. Anesthesia was induced by intravenous (I.V.) thiopental sodium and maintained with enflurane / N2O / oxygen. Vital signs were stable until 2 hours into surgery, when patient developed sudden profound hypotension (systolic pressure 60 mmHg) with tachycardia, skin flushing and bronchial wheezing shortly after infusion of only a few milliliters of 4th unit of whole blood. Blood transfusion was immediately stopped, anesthetic agents were discontinued, and 100% oxygen was administered. Rapid administration of I.V. fluids was begun and I.V. hydrocortisone along with pheniramine were administered. Patient was successfully treated and eventually discharged from the hospital. In conclusion, besides hemolytic transfusion reaction, anaphylactic transfusion reaction may cause severe hypotension. One should be aware of the potential for adverse effects including anaphylaxis, should recognize them immediately and treat them appropriately.

BACKGROUND: Ambulatory surgery has become popular because patients believe it allows them greater control over their business and personal lives and because third party payers find it reduces cost. This study was designed to compare the characteristics of induction and recovery as well as the safety of propofol with those of midazolam used for intravenous anesthesia in outpatient cystoscopy. METHODS: 56 healthy consenting outpatients were randomly assigned to receive either bolus of propofol (2 mg/kg, n=29) or midazolam (0.1 mg/kg, n=27) for anesthesia in outpatients cystoscopic procedure. All patients also received bolus of fentanyl 1ug/kg before induction and N-M blocking agent was not injected for maintenance of spontaneous respiration. Mean arterial pressure, HR and SpO2 were recorded and induction time (time to spontaneous eye closure), recovery time (time to response, time to orientation, time to ambulation) and adverse effects were evaluated. RESULTS: The results were as follows; 1) Both propofol and midazolam produced smooth induction, but caused significant respiratory depression. 2) The time of induction and postoperative recovery (time to ambulation) was faster in propofol than in midazolam. 3) There were less postoperative side effects (nausea, vomiting, dizziness) in propofol than in midazolam. 4) There were more cardiovascular depression in propofol than in midazolam. CONCLUSION: These results suggest 1) that propofol has significant advantage over midazolam in outpatient surgery, where early ambulation and discharge is desirable and 2) that both propofol and midazolam should be administered by expert anesthesiologist only when ventilatory assistant device with oxygen is immediately available.

A 44-year-old man showed recurrent paroxysmal amnesic attacks following viral encephalitis which, despite antiepileptic treatment, developed into status epilepticus. Interestingly, the amnesic attacks mainly consisted of amnesia for retrograde events. After recovery from status, he showed a persistent amnesia which was characterized as disproportionate retrograde amnesia for the past 20 years. We attribute the amnesic attacks in the acute stage to a transient epileptic amnesia and the profound retrograde amnesia in the chronic stage to status- or infection-related focal brain damage.

PURPOSE: Osteosarcoma is the most common primary malignant bone tumor in children and adolescents. Although survival rate of osteosarcoma patients has markedly improved, about 20-30% of patients still have a relapse. This study was aimed to find factors that influence postrelapse survival of osteosarcoma in childhood and adolescents. METHODS: Between 1985 and 2004, of 461 patients who were diagnosed and treated as osteosarcoma in Korean Cancer Center Hospital, 180 patients with recurrent osteosarcoma were retrospectively reviewed. We examined survival rates and analyzed prognostic factors, such as relapse site, post-relapse treatment methods, pathologic response to neoadjuvnat chemotherapy, metastasis at first diagnosis, and relapse free interval. RESULTS: The overall recurrence rate of patients with osteosarcoma was 39%. The 5-year and 10-year postrelapse survival rates in the recurrent osteosarcoma were 13% and 4%, respectively. The 5-year post-relapse survival rate was influenced by site of relapse (lung, 39%; local, 0%; lung & bone, 25%; others, 12%; P<0.05), relapse-free interval (<12 months, 13%; > or =12 months, 44%, P<0.05), and post-relapse treatment methods (with surgery, 38%; without surgery, 11%; P<0.05). CONCLUSION: The survival rate of recurrent case is very low after 10 years, so new second-line chemotherapy and active treatment is needed to increase survival. Aggressive surgery with the removal of recurrence sites combined with multi-agent chemotherapy could either cure patients with recurrent osteosarcoma or significantly prolong their survival.

Bickerstaff 's brainstem encephalitis (BBE) is characterized by acute ophthalmoplegia and ataxia. Some patients with BBE show mental changes, pyramidal signs and sensory disturbance. A forty-three year old woman was diagnosed as BBE in 1996. In 2000, she admitted again with complaints of ataxia and ophthalmoplegia. She was diagnosed as recurrent BBE and an overlap of Guillain-Barre syndrome (GBS). This is the first case of an overlap of BBE and GBS, as well as BBE in Korea.

BACKGROUND: We evaluated whether the time required for a seizure to spread contralaterally, interhemispheric propagation time (IHSPT) could be related to post-surgical outcome in temporal lobectomy. METHODS: We performed a retrospective study of 28 patients. All patients had previously undergone a phase I presurgical evaluation including MRI and video-EEG monitoring with scalp and sphenoidal electrodes, which strongly suggested the diagnosis of mesial temporal lobe epilepsy, but proved inadequate to lateralize the epileptogenic zone. All patients performed the video-EEG monitoring with bilateral subdural strip electrodes on their basal and mesial temporal area and unilateral temporal lobectomy with a minimum of 1-year follow up postoperatively. IHSPT was divided into two categories, 0~5.0 seconds, 5.1 seconds or longer. RESULTS: Sixteen patients (57.1%) were seizure free and 12 suffered persistent seizures. A prolonged IHSPT (> 5.0sec) significantly correlated with a favorable surgical outcome (P = 0.05). Hippocampal atrophy on MRI significantly correlated with prolonged IHSPT (P<0.05). CONCLUSIONS: Our result suggests that hippocampal atrophy on MRI and IHSPT can predict the surgical outcome and may be used as the selection criteria of temporal lobectomy for patients with intractable temporal lobe epilepsy.

PURPOSE: This study aimed to assess whether a young age at the time of diagnosis with osteosarcoma has value to predict the prognosis. MATERIALS AND METHODS: Sixty-seven children with stage II osteosarcoma were stratified according to the age of 10. There were 32 preadolescents (< or =10 years) and 35 adolescents (10 < age < or = 15 years). The patients were analyzed for their clinical characteristics, the histologic response to preoperative chemotherapy, event-free survival (EFS) and the patterns of relapse. RESULTS: After a median follow-up of 54 months (range: 6~153 months), the 5-year EFS of the preadolescent and adolescent groups was 64.5+/-9.3% and 58.2+/-9.1%, respectively, and age did not have any statistical significance for survival (p=0.55). Cox regression analysis revealed that both the serum level of alkaline phosphatase and the histologic response to preoperative chemotherapy were significantly related to survival of the 67 patients. Those patients aged less than 7 years responded poorly to preoperative chemotherapy and their rate of amputation was 43%. However, their 5-year EFS was not statistically different from the older patients (57.1+/-18.7 vs 67.7+/-6.3%, respectively, p=0.58). CONCLUSIONS: We could not find any statistical difference in the clinical characteristics and survival from osteosarcoma for the preadolescents and adolescents, so the current approach of having the same protocol for both groups of patients seems to be reasonable.

Emery-Dreifuss muscular dystrophy is characterized by 1) early contractures of the elbows, Achilles tendons, and postcervical muscles, 2) slowly progressive muscle wasting and weakness with a humeroperoneal distribution in the early stages, and 3) cardiomyopathy with conduction defects and risk of sudden death. The inheritance is usually X-linked recessive but can be autosomal dominant and recessive. We report a case of 28-year old woman who presented with dizziness, palpitation, and progressive muscular weakness. Her ECG revealed high degree AV block and muscle biopsy demonstrated diffuse degenerative change consistent with Emery-Dreifuss muscular dystrophy. She was diagnosed as autosomal dominant Emery-Dreifuss muscular dystrophy by characteristic clinical features, and findings of ECG, nerve conduction test, electromyography and muscle biopsy findings. A VVI-type permanent pacemaker was implanted.

BACKGROUND: Recent studies have suggested that the outcomes of the patients with acute renal failure (ARF) may related to delivered dose of dialysis. In such context, a number of investigators have reported about delivered dose of dialysis and its contribution to outcomes of ARF, using Kt/V. The purpose of the study was to evaluate actual delivered dose of dialysis in intermittent hemodialysis (HD) in critically ill ARF patients, clinical factors contributing delivery of dialysis dose, and relationship of delivered dialysis dose and survival. METHODS: Delivered and prescribed dose of dialysis, presented as Kt/V, were measured in ARF patients intermittent HD in intensive care unit of Inha University Hospital from January 1999, until December 1999, using single pool urea kinetic model. RESULTS: All subjects received intermittent HD of 6.4+/-4.8 times with mean of 225.6+/-40.4 min per session. Overall survival was 55.5%. Prescribed Kt/V in all subjects was 1.24+/-0.39, but actual delivered Kt/ V was 1.08+/-0.17. A mean delivered/prescribed Kt/V ratio was 87.1+/-43%. Duration of HD session (R= -0.547, p=0.019), Cleveland Clinic Foundation Severity Score (R=-0.486, p=0.041), and frequency of hypotensive episodes (R=-0.419, p=0.043) were significantly correlated with delivered/prescribed Kt/V ratio. Delivered dose was under 1.2 in 66.7% of the subjects. Survival rate of these patients was 50.0%, which was lower as compared to 66.6% of the patients with delivered dose over 1.2. Patients with low delivered dose (Kt/V<1.2) showed significantly low prescribed dose and short HD time (p<0.05). Delivered Kt/V was correlated with BUN at initiation of dialysis, HD duration, and prescribed Kt/V (p<0.05). Non-survivors showed significantly low initial serum creatinine, low CCF severity score, high frequency of hypotensive episodes, and less use of heparin (p< 0.05). Prescribed Kt/V was not different between survivors and non-survivor (1.22+/-0.30 vs 1.31+/-0.45), but delivered Kt/V (1.17+/-0.17 vs. 1.04+/-0.17; p<0.05) and delivered/prscribed Kt/V (95.9+/-22.6% vs. 73.9+/-15.6%; p<0.05) were significantly higher in survivors than in non-survivors. CONCLUSION: In ARF patients, the delivery of dialysis was significantly lower than as was expected. Delivered/prescribed Kt/V was about 87% and more than half of the patients received intermittent HD of Kt/V less than 1.2. Better survival was associated with higher delivered dose of dialysis. We need further prospective studies about the causal relationship between delivered dose of dialysis and outcomes in ARF patients.
