Carbon monoxide poisoning is one of the most serios health problems in Korea, because we have been encountered with the highest incidence of CO poisoning in the world due to the unique heating system in home called "ondal". We opened Hyperbaric chamber unit in the Seoul National University Hospital last Jan, 1969. We have treated 848 patients as of Sept. 30., 1972, around 44 months period. We collected the informations on the environmental conditions of the place where CO intoxication actually occurred by filling up the questionaire from 505 patients. The following finding were obtained. 1. Age distribution showed that the highest incidence was found in the younger age group between age of 10 to age of 29 in both sex. 2. Sex ratio of the patients was 1:1.14. 3. The socio-economic level of the patient was relatively low. 4. Housewife & housemaid were the major victims of the intoxication in the female patients & in the case of the male patient, occupational backgrounds were diverse. 5. Many patients form the middle class experienced the intoxication bu sleeping at newly built room. 6. Many intoxication has been occurred in the structure of houses where communicating doors are existing between living room & kitchen. 7. All findings obtained taught us again that CO poisoning is the serious by-product of the national fuel policy which put emphasis on the use of coal & socio-economic status is very important parameter in this hazards.

Compliance of epileptic patients is one of the most important factors for adequate therapy. Recently, it had been shown that the variability of three serial measurement of the serum levels of antiepileptic drug(AED) may be used as an indication of the degree of compliance. Coefficient variation(CV) of serum drug levels calculated by only one AED had been used to determine the compliance in epileptic patients who took multiple AEDs. We attempted to evaluate the CV of AEDs and then find the objective clue of compliance and the compatible therapeutic planing according to CV. Ninety seven epileptic patients of outpatients department of the Gyengsang National University Hospital were entered to this study. All patients were taking medication at least for 6 months without any changes of drug regimen. Patient's information was acquired by reviewing the chart and interview with questionnaire. With these informations, we determined the compliance of the patients. Antiepileptic serum levels were measured three times at intervals of at least two to four weeks apart, and their CV was calculated. We compared the CV between the compliant and non-compliant group in each AED(phenytoin, carbamazepine , valproic acid) and three drugs in the compliant group. The mean CVs of phenytoin, carbamazepine and valproic acid in the compliant group were 18.3+/-13.0, 15.2+/-10.2 and 23.8+/-8.9, respectively(mean+/-SD). The mean of CV in the compliant and the non-compliant group were 17.9+/-10.9 and 38.8+/-27.2, respectively. The CVs of the compliant group were significantly lower than those of the non-compliant group(p<0.05). However, CVs had no significant difference between three antiepileptic drugs. This study showed that CVs of AEDs were not different between each AEDs, even though they possess different pharmacokinetic properties. Therefore, the CV of one AED can be used in determining the compliance of the epileptics who are taking multiple AEDs.

BACKGROUND AND PURPOSE: Neuropathological studies have demonstrated that multiple system atrophy (MSA) produces selective atrophy of the putamen with sparing of the caudate nucleus, while both structures are spared in idiopathic Parkinson's disease (PD). In this study we evaluated the clinical efficacy of using putaminal atrophy in brain MRI to differentiate MSA and PD. METHODS: We measured the putamen/caudate volume ratio on brain MRI in 24 patients with MSA and 21 patients with PD. Two clinicians who were blinded to the patients' diagnoses and to each other's assessments measured the volume ratio using a computer program. RESULTS: The measured volume ratios of the two investigators were highly correlated (r=0.72, p<0.0001). The volume ratio was significantly lower in MSA (1.29+/-0.28) than PD (1.91+/-0.29, p<0.0001). Setting an arbitrary cutoff ratio of 1.6 resulted in about 90% of patients with MSA falling into the group with a lower ratio, whereas more than 80% of patients with PD belonged to the other group. CONCLUSIONS: The present results demonstrate that putaminal atrophy in MSA as measured on brain MRI represents an effective tool for differentiating MSA from PD.

Postoperative epidural hematoma (EDH) usually present with neurological deficit. Massive EDH presenting with only severe pain without neurological deficit are rare. Atypical presentations of postoperative EDHs may lead to delayed diagnosis and treatment. We present three such cases after posterior cervical spine surgery. Three patients presented with severe neck pain and spasms without motor deficits several days after posterior cervical decompressive procedures. Imaging studies identified compressive EDHs at the surgical site with severe compression of the spinal cord. All were treated with emergent decompression, with resulting improvement of symptoms and pain relief without further neurological sequelae. In conclusion, postoperative EDHs after posterior cervical spine surgery may result in minimal neurological deficit. Our report reminds surgeons to keep this possibility in mind when patients complain of unusually severe neck pain and spasms after posterior cervical spine surgery.

INTRODUCTIONRight siting has been actively advocated to mitigate rising healthcare costs as well as to free up tertiary resources for the provision of care to more complex patients, research and education. There are, however, concerns that in a block budget setting right siting will reduce patient volumes, thus impacting on subsequent funding allocations and also patient revenues. We sought to determine through modelling and simulation the financial and volume impacts of right siting of endocrinology outpatients in a large tertiary hospital in Singapore.

MATERIALS AND METHODSData were collected prospectively on patient casemix including complexity (complex defined as requiring specialist care), time required for consultations and revenues garnered. The data were used to simulate 2 scenarios: right siting of all simple cases with freed up resources directed to research and teaching (research scenario) and right siting of all simple cases with replacement by complex cases (service scenario).

RESULTSThe department sees an estimated 33,000 outpatients per year with a total annual outpatient revenue of $8.6 million. The research scenario would see a decline in patient volume to 11,880 cases per year which would result in a corresponding decrease in revenue of $5 million and freeing up of 2.8 hours/ week for each staff. The service scenario yields a drop in patient volume of 9500 per annum and a drop in revenue of $1.9 million.

CONCLUSIONRight siting reduces tertiary care patient volumes and revenues and may discourage right siting efforts. A viable business model for the tertiary institutions is needed to facilitate support for right siting.

INTRODUCTIONIt is difficult to counsel the anterior cruciate ligament (ACL) deficient patient considering surgical reconstruction on the likelihood of eventual return to sports as information on this is lacking, especially in the Asian context. We wanted to determine how many of our patients who had ACL surgery returned to their previous levels of sports, 5 years after their surgery. For those that had not returned to their previous levels of sports, we wanted to identify their reasons for not doing so.

MATERIALS AND METHODSBased on our inclusion criteria of a minimum 5-year follow-up after primary ACL reconstruction, 146 patients were identified for assessment. Sixty-four patients were successfully recalled. The mean age of our patients was 24.8 years (range, 18 to 40). The patients completed the Lysholm Knee, Tegner activity and the Subjective International Knee Documentation Committee (IKDC) questionnaires. Clinical examination of the operated knee was performed according to the Objective IKDC evaluation form and with a KT-1000 arthrometer.

RESULTSThe mean Lysholm score was 85.2 and the mean subjective IKDC score was 79.5. 81.2% of our patients had normal or nearly normal knees (IKDC A or B) with the remaining 18.8% at IKDC grade C. The mean side-side difference for anterior translation using the KT-1000 arthrometer was 1.2 mm. The median pre-injury Tegner activity level was 7 and the median 5-year post-surgery Tegner activity level was 6. Nineteen patients did not return to their pre-injury sports levels because of social reasons and were excluded. From the remaining 45 patients, 28 patients (62.2%) returned to their previous level of sports and 17 patients (28.8%) did not return to their previous level of sports. Of whom, 9 (20%) said that they did not return due to fear of re-injury and the remaining 8 (17.8%) said they had not returned because of knee instability and pain. At 5 years, the subgroup of patients who had returned to sport had the best scores: Lysholm (88.5), subjective IKDC (84.6) and IKDC Grade A&B (89.3%). When we compared this with the subgroups that did not return to sport because of fear of re-injury and because of an unstable knee, we found that the difference in knee outcome scores between these 3 groups were statistically significant.

CONCLUSIONSixty-two per cent of our patients returned to their previous level of sport at 5 years after ACL reconstruction. Fear of reinjury is an important psychological factor for these patients not returning to sports. Our results would allow the attending surgeon to counsel the ACL deficient patient who is considering surgical reconstruction the likelihood of eventual return to sports.
