As Kelsey stated “Four out of five individuals will have a significant complaint of back painat one time or another in their lives and impairment of the spine are the most frequent cause of time lost from work”., low back pain affects the quality of life for just about everyone, medical and economic impacts of low back pain are enormous. Nevertheless, neither the government not industry has been seriously involved in the study of the cause, prevention, and management of back pain. The purpose of this study was to review and analysis the clinical materials of low back painand draw differences, if any, between discogenic and stenotic low back pain. Three hundreds and fourty nine cases suffering from low back pain and/or sciatic pain, excluded fresh traumatic and inflammatory conditions of the spine, have been admitted and treated at Dept. of orthopaedic surgery, Eul-Ji General Hospital, Dae-Jeon from May, 1981 to April, 1984. They were consisted of H.N.P. (172 cases), Spinal stenosis (61 cases), Spondylolisthesis (42) cases), Degenerative joint Disease of the spine (48 cases), and Others (26 cases). Among them, two hundred and twenty six cases who were followed more than four months were mainly subjectecl to this study.

Tufted hair follliculitis is a localized, inflammatory and exudative disease of the scalp characterized by a tufted appearance of the scalp hairs emerging from single follicular openings, and may result in permanent and irreversible scarring alopecia. We report two cases of tufted hair folliculitis in a 53-year-old woman and a 47-year-old man. They had several areas of scarring alopecia with multiple bundles of hairs emerging from single follicular orifices. Histopathologic findings were typical for tufted hair folliculitis. The patients were treated successively with oral antibiotics and with topical application of clindamycin.

Thyroid dysfunction has heen reported as a side effect of alpha-interferon(IFN) therapy. The incidence of thyroid disorders was 1.2-12%' duripg 1FN therapy for chronic active hepatitis. We experienced a case of hypothyroidism developed after IFN therapy in a 48 year-old man with chronic hepatitis B. Baseline thyroid function before IFN therapy was normal and thyroid auioantibodies were also negative. High tiers ol' antimicrosomal antibody and anti-thyroglobulin antibody appeared and severe hypothyroidism followed at 6 months after starting the IFN therapy.

Somatosensory evoked potentials(SSEP's) are commonly employed to monitor cerebral and spinal cord function in patients with various lesions in the nervous system. In this study, we evaluated SSEP's as a means of measuring not only neurophysiological function but also the alteration of blood folw in the territory of cerebral ischemia. We examined SSEP's and regional cerebral blood flow(rCBF) in the bilateral suprasy1vian gyri following unilateral middle cerebral artery(MCA) occlusion in 15 cats(Group II). The duration of arterial occlusion was 30 minutes followed by 1 hour of recirculation. Five additional cats served as sham-operated groups(Group I). The animals in Group II were divided into 2 subgroups according to the change of the observed rCBF in the ipsilateral hemisphere. Immediately after MCA occlusion, rCBF decreased from around 50 to 14mg/100g/min. Decreased rCBF was remained below 20ml/100g/min throughout the ischemic period in 6 cats(Group IIb), and in the remaining 9 cats, the decreased rCBF was increasing during ischemia although the blood flow was subnormal(Group IIa). The recovery of rCBF during recirculation was faster in Group IIa than in Group IIb. In Group IIa and IIb, there was a significant slowing of the interpeak latency between dorsal column nuclei(Fz) and the major negative deflection(MN) (P<0.05) in the ipsilateral hemisphere and a precipitous decrease in the amplitude of the ipsilateral P1-MN complex immediately after occlusion(P<0.05). In Group IIb the suppressed SSEP's did not show any recovery during ischemia, and recovered late during recirculation. In Group IIa the suppressed SSEP's tended to recover during recirculation. In Group IIa the suppressed SSEP's tended to recover during ischemia and recovered early during recirculation. SSEP's were not completely abolished throughout the experiment in any experimental grup. The relationship between the changes in rCBF and amplitude of SSEP's in the ipsilateral hemisphere was significant(r=0.943, P<0.05) during occlusion of the middle cerebral artery in Group IIa. However there was not any other relationship in the other groups or among other wave components. These results indicate that the suppression of SSEP's and their failure to recover during focal cerebral ischemia correlate with the lack of collateral circulation. Furthermore, SSEP's can be useful means to evaluate the reversibility of cerebral ischemia, which may be decided by existence of collateral circulation. And it appers that the time threshold for abolition of SSEP's is more than 30 minutes in focal cerebral ischemia in the cat.

BACKGROUND AND OBJECTIVES: The vascular endothelial growth factor (VEGF), a heparin binding growth factor specific for endothelial cells, is both a potent enhancer of vascular permeability and an angiogenic growth factor. The purpose of this study was to investigate the semi-quantitative expression levels of multiple VEGF mRNA splicing variants in endotoxin-induced otitis media with effusion (OME) of rat. MATERIALS AND METHODS: We instilled endotoxin and saline as a control into the middle ear cavity of the rat, and middle ear mucosa were taken at 0 h, 1 h, 3 h, 6 h, 12 h, 1 d, 3 d, 7 d, and 14 d. The levels of splicing variants of VEGF transcripts were evaluated by semi-quantitative RT-PCR. RESULTS: Expression of VEGF164 mRNA and VEGF120 mRNA was first identified at 1 h after endotoxin instillation and was dramatically increased between 6 h and day 1 and then progressively decreased by day 7. Expression level of VEGF120 mRNA was 1.34+/-0.27 fold higher than that of VEGF164, and the expression level of VEGF164 was 3.89+/-0.97 fold higher than that of VEGF188. CONCLUSION: These results suggest that VEGF may be primarily responsible for the increased vascular permeability in OME and that it seems to play a significant role in the pathogenesis of OME.

PURPOSE: Diagnosis of a hemodynamically significant patent ductus arteriosus (PDA) that should be treated is difficult to determine by clinical and echocardiographic examination. The purpose of this study is to clarify the usefulness of diastolic flow velocity (DFV) of the left pulmonary artery (LPA) determined by echocardiography in the assessment of significant PDA in preterm infants. METHODS: Clinical and echocardiographic findings, including DFV in LPA, of PDA were evaluated at 24 hours, 48-72 hours of age and after indomethacin treatment in thirty-nine infants ranging from 25 to 34 gestational weeks of age. DFVs of the study group (N=13) with significant PDA were compared with those of healthy control group (N=26) without significant PDA. RESULTS: DFVs in healthy preterm infants were high in the first few days and were significantly decreased after spontaneous ductal closure. DFVs in preterm infants with significant PDA who underwent indomethacin treatment were significantly higher than that of healthy control infants. After indomethacin treatment, DFVs in this study group remained high with continuing significant PDA and markedly decreased with disappearance of significant PDA. Until ductus arteriosus closed, DFVs showed a significant correlation with the magnitudes of ductal shunt. A cutoff value for DFV of 30 cm/sec showed a sensitivity of 77% and a specificity of 92% as a predictor of significnat PDA in preterm infants. CONCLUSION: Measurement of DFV in LPA by echocardiography is a useful method for assessing the significnat PDA which may require treatment in preterm infants.

Rudimentary meningocele, also known as a 'variant of primary cutaneous meningioma' or 'acoelic meningeal hamartoma', is an unusual developmental anomaly in which meningothelial elements are found in the skin. A 8-month-old girl has a well-circumscribed, alopecic, atrophic patch on the midline of the occipital area since birth. Histologically, pseudovascular spaces lined with flattened or cuboidal cells were seen in the papillary and upper reticular dermis without collagen bodies. These flattened or cuboidal cells were positive for vimentin, but negative for EMA, immunohistochemically. Radiographic finding of the scalp revealed no underlying bony defect.

Infantile acropustulosis is characterized by recurrent crops of pruritic vesicopustules that are found primarily on the distal extremities of infants. Herein we report a 20-month-old female baby, who had a past history of scabies, with recurrent episodes of 1-2 mm sized, intensely pruritic vesicopustules on both hands and feet. The mite smear for scabietic mites, Gram stain for bacteria, and KOH smear for dermatophytes of lesion were all negative. Tzank test of the vesicle revealed many neutrophils. She was treated with dapsone (2mg/kg/day) and the pruritic vesicles and pustules had disappeared by 48 hours.
