Histiocytosis X(Langerhans cell histiocytosis) is a rare prolifertive disorder of Langerhans cells that includes Lettere-Siwe disease, Hand-Shiiller-Christian his ase and eosinophilic granuloma. Since many authors have reported in anintermediate and poarl classified form histiocytosis X has a namenclatural had nosologic problem. We report a case benign cutaneous variant of histiocytisis X. A four-month-old boy had shown multiple skin-colour papules on the trunk, head and nik for one month. Extensive in- vestigations failed to detcct any systemic involvement. The clixron microscopic findings of the skin biopsy specimen were Qefinitely diagnostic for histiocytosi. X Since he did not sbow evidence of internal organ involvernent and any further progression of he skin lesion, no therapy was given. Over the next two months the disease underwent spontane us and complete remission.

STUDY DESIGN: We report two cases of symptomatic spinal epidural lipomatosis (SEL) associated with long-term use of steroid medication OBJECTIVES: The purpose of this study was to assess the clinical characteristics, diagnosis and treatment of symptomatic spinal epidural lipomatosis. SUMMARY OF LITERATURE REVIEW: Spinal epidural lipomatosis is a condition in which excess adipose tissue is deposited circumferentially about the spinal cord in the epidural space. It can present neurologic symptoms including back pain, radiculopathy or cauda equina. Magnetic resonance imaging is the most helpful dignostic means and should be used initially if suspected. Treatment is decompressive laminectomy and debulking of fat. MATERIALS AND METHODS: Two cases of lumbar epidural lipomatosis with neurologic symptoms were discussed and evaluated by physical examination, postmyelography CT and MRI. RESULTS: Two cases were treated with decompressive laminectomy and debulking of fat. Increased accumulation of the fatty tissue was seen predominently in posterior and posterolateral epidural space of the spinal canal, displacing and compressing the lumbar spinal cord anteriorly. Both gross and histologic evaluation revealed overgrowth of unencapsulated normal appearing fat consistent with spinal epidural lipomatosis. One case was demonstrated gradual improvement in symtoms after operation but the other was died due to medical problems. CONCLUSION: The authors reviewed the literature and reported the results of operative treatment of patients with lumbago, radicular pain and intermitent claudication caused by epidural lipomatosis of lumbar spine and degenerative spinal stenosis.

The purpose of this study was to evaluate the association between glycated hemoglobin (HbA1c) and all-cause mortality in type 2 diabetes mellitus. We conducted a community-based prospective cohort study of 352 type 2 diabetic patients aged 30-92 who participated in a community diabetes complications screening program in Gokseng-gun, Jeollanamdo, Korea. HbA1c levels were categorized as <6.5%, 6.5-6.9%, 7.0-7.9%, 8.0-8.9% and ≥9.0%. Patients were followed up on for a mean of 6.9 years. The Cox proportional hazards model was used to evaluate the relationship between HbA1c levels and all-cause mortality. During the mean follow-up period of 6.9 years, 77 patients (21.9%) died. A J-shaped association was found between HbA1c and all-cause mortality, with the lowest mortality at 6.5-6.9% of HbA1c levels. Compared to patients with HbA1c of 6.5-6.9%, patients with <6.5%, 7.0-7.9%, 8.0-8.9% and ≥9.0% had an adjusted hazard ratio (95% confidence interval) for all-cause mortality of 1.71 (0.76-3.84), 1.23 (0.53-2.82), 1.32(0.51-3.44) and 2.66 (1.01-7.02), respectively. We found a J-shaped association between glycated hemoglobin and all-cause mortality in Korean type 2 diabetic patients.

Background: This study was to investigate the cancellation rate and trend of orthopedic surgeries during the novel coronavirus disease 2019 (COVID-19) pandemic. Moreover, we assessed the psychologic status of orthopedic healthcare workers, and investigated the details of the preventive surgeries underwent in COVID-19-positive patients. Methods: For 3 months after January 20, 2020, cancellation rates of elective surgeries were investigated, and the number of elective surgeries conducted in the same period over the last two years was compared. Four different questionnaires were used to investigate psychologic status among the orthopedic health care workers. We compared the outcomes according to occupation (physician or nurse), and type of work (faculty staff or resident physician). Outcomes according to occupation and type of work were compared. Preventive surgeries underwent in patients who could not wait for the results of the COVID-19 diagnosis were investigated. Results: Spine and hip surgery had relatively lower cancellation rates, and elective surgeries were significantly reduced. During the initial pandemic, the cancellation rate of orthopedic elective surgeries was significantly higher than in the same period of the previous year and was different for each subdivision depending on the degree of pain or disability. The psychological outcomes were within the normal range and there were no significant differences between groups. After preventive surgery, all medical staff involved in the operation tested negative. Conclusion During the COVID-19 pandemic, the cancellation rate of orthopedic elective surgeries was significantly higher than in the same period of the previous year. Orthopedic health care workers did not seem to have significant psychological distress. As a result of the preventive surgery in specialized facilities, all the medical staff who participated in the operation tested negative.

BACKGROUND: The rate of rise of left ventricular(LV) systolic pressure, dp/kt, and the peak ejection rate(PER) of LV may be more accurate indices for assessing LV systolic function than ejection fraction(EF). Both can be easily obtained by noninvasive methods, M-mode echo/phonocardiography and automated border detection(ABD) echocardiography, respectively. Mean dp/dt by M-mode echo/phonocardiography and PER by ABD echocardiography were compared with mean dp/dt by Doppler echocardiography. METHODS: Twenty-one adult patients who had normal sinus rhythm, mitral regurgitant signals by continuous wave Doppler echocardiography and an apical 4 chamber view of LV in which at least 75% of the endocardium was clearly visualized were selected for our study. The off-line estimation of LV end-diastolic volume (1) were performed by the method of disc, after manually tracing the endocardial border on the apical 4 chamber view and EF was calculated. M-mode echocardiography of the aortive valve and phonocardiography were simultaneously recorded on the strip chart to measure the isovolumic contraction time(dtM). A blood pressure (2) and LV end-diasolic pressure(LVEDP) was assigned 20mmHg in patients with Q wave myocardial infarction or EF< or =40% and 10mmHg in others. The mean dp/dtM during isovolumic contraction time was calculated as (aortic diastolic pressure-LVEDP)/dtM and was compared with the Doppler-derived mean rate of LV pressure rise(dp/dtDoppler) over the time period between velocities of 1 and 3m/sec on the ascending slope of the Doppler velocity spectrum. ABD system was used to measure the changes in LV volume and PER on the apical four chamber view. PER was compared with mean dp/dtDoppler. RESULTS: Mean dp/dtM positively correlated with mean dp/dtDoppler(r=0.73, p<0.001), but the limits of agreement between two methods were somewhat wide(-659-937mmHg/sec). PER also positively correlated with dp/dtDoppler and EF(r=0.73, p<0.001 ; r=0.80, p<0.001). CONCLUSIONS: Mean dp/dtM by M-mode echo/phomocardiography and PER by ABD echocardiography may be useful indices for assessing LV systolic function.

The authors experienced 52 patients with myasthenia gravis who were diagnosed at the Department of Neurology, Yeungnam University Hospital from August 1985 to January 1996. The following results were obtained through diagnostic evaluation and treatment. 1. The ratio of male to female was 1:1.7 and the most prevalent age group was second decade. 2. The most common initial presentation symptom was ocular(71.2%) and the peak incidence group was stage I (69.3%) according to the modified Osserman's classification. 3. In 16 patients(30.8%), it took more than a year to diagnose due to symptoms which were relapsed and remitting. 4. Of 52 patients, 2 cases were associated with thyroid disease(3.8%) and 2 with insulin-dependent diabetes mellitus(3.8%). 5. All of those who received anticholinesterase and corticosteroid therapy were improved with the exception of 5 cases which were improved after thymectomy and/or plasmapheresis.

We investigated HBV markers in serum and cerebrospinal fluid of 50 subjects with neurologic disorders or other disorders, who visited Dept. of neurology, college of medicine, Yeungnam University, from April-1 to August-31 1994 and were performed cerebrospinal fluid analysis to investigate the detection rate of HBV markers in cerebrospinal fluid and the possibility of neurologic disorders associated with HBV infection. The results were as follows. The positivity of HBsAg and. HBV prevalence rate in serum were 6(12.04) and 37(74.0%). Thf, number of patient with HBsAg, only anti-HBV and no markers were 6(12.0%), 31(62.0%) and 13(26.0%), respectively. The positivity of HBsAg and HBV prevalence rate in cerebrospinal fluid were 3(6%) and 18(36.0%). The number of patient with HBsAg, only anti-HBV and no markers were 6(100.0%), 12(38.7%) and 0(0.0%) respectively. The number of patient with virus associated diseases(VAD) and non virus associated diseases(NVAD) were 26(52%) and 24(48%). The HBV prevalence rate in serum of VAD and NVAD groups were 88.5% and 58.3% (p<0.05). The HBV prevalence rate in CSF of VAD and NVAD groups were 53.8% and 16.7%(p<0.05). The HBV prevalence rate in serum and CSF of VAD and NVAD groups were 60.9% and 28.6%
