Eighty three rickets could be diagnosed at our department during eight years from August of 1969 to July of 1977. Among them fourteen children, whose radiographs and clinical description were precise with well-documented follow-up study of more than one year, were subjected to this analysis. Evaluation of the healing and correction of the lower leg deformity in these rachitic children obtained the following results. 1. Among fourteen rachitic children, thirteen patients (26 legs) showed varus and one patient (2 legs) showed valgus deformity. 2. Mean mechanical tibio-femoral angle showed shift from the initial 16.1°±5.3° to 5.5°+4.0° at final visit, which indicated the gradual correction of the deformity with the advance of the ages of children. The follow-up study after three years in this series showed that the correction became almost complete. 3. At the epiphyseo-metaphyseal region of the distal femur, the initial angle showed two distinct trends of change. The initial varus angle more than 7 or 8 showed the decrease at the later follow-up study, while the initial angle less than 7 or 8 showed the increase. 4. The epiphyseo-metaphyseal region of the proximal tibia showed the minimum change of angle. Mean angle of deviation from the vertical line was 3.7°±2.9° at first visit and 2.6°± 2.4°at final visit. The least degree of varus and the trend toward valgus observed in this region may refiect its compensatory activity against the varus deformity of the leg as a whole. 5. The epiphyseo-metaphyseal region of the distal tibia showed the maximum degree of varus at both initial and final check although the greatest degree of correction was attained. The initial mean varus angle of 23.9°±9.2° became 12.9°±7.1° at final visit. 6. The results of this study have shown that the correct evaluation of the rcchitic leg deformity is possible with measurement of the mechanical tibio-femoral angle and that the deviation angle of each epipyseo-metaphyseal region is preferable.

PURPOSE: To report a case of endophthalmitis associated with Vibrio vulnificus septicemia. METHODS: Vibrio vulnificus septicemia patient was referred to us in consultation for abrupt onset left visual loss, severe periorbital swelling and conjunctival injection. RESULTS: Left eye showed suppurative intraocular inflammation. With a clinical impression of V. vulnificus endogeneous endophthalmitis, culture for causative organisms and intravitreal antibiotics injection were done. Two days later, we performed pars plana lensectomy, pars plana vitrectomy, intravitreal antibiotics, SF6 gas injection. Intraocular inflammation was subsided after operation, and the anatomical structure of the eyeball was preserved CONCLUSIONS: Immediate ophthalmologic examination is mandatory for ruling out endophthalmitis when Vibrio species septicemia patient complains of ophthalmic symptoms, such as blurred vision or ocular pain. When clinicians diagnose endophthalmitis, make an effort to identify causative organisms. When bacterial infection is suspected, inject antibiotics intravitreously or vitrectomy must be done as faster as possible.

PURPOSE: To investigate the change of the Beta adrenergic system in the rat visual cortex and superior colliculus after visual deprivation during a critical period of postnatal development. METHODS: The changes of beta 1 and beta 2 adrenergic receptor mRNA were investigated by using northern blot analysis in the rat visual cortex and superior colliculus. The right eyelid of visually deprived rat was sutured at the 10th postnatal days. After visual deprivation for 4 weeks, the rat were sacrificed and the visual cortex and superior colliculus tissues were removed for analysis. RESULTS: Beta 1 and beta 2 adrenergic receptor mRNA expression was decreased in the contralateral visual cortex to the deprived eye. In the superior colliculus, beta 2 adrenergic receptor mRNA expression increased in both sides, but a much greater increase was shown in the ipsilateral superior colliculus than the contralateral side. CONCLUSIONS: These results suggests that visual deprivation during a critical period of postnatal development influences the beta adrenergic system in the rat visual cortex and superior colliculus.

PURPOSE: To report one case of neurilemoma of the bulbar conjunctiva with a review of the relevant literature. CASE SUMMARY: A 15-year-old girl presented with a bulbar conjunctival mass in the right eye. There were no other medical or ophthalmologic problems. The patient wanted to remove the mass for cosmetic reasons. We performed an excisional biopsy and simple wound closure. The mass was composed of bipolar spindle shaped cells that were arranged in bundles and fascicles in dense fibrous tissue. Immunohistochemical staining for the S-100 protein was positive. Two months after mass excision, there was no evidence of recurrence. CONCLUSIONS: We successfully treated a case of bulbar conjunctival neuriliemoma by simple excision.

PURPOSE: To determine the place and the limit of the arthroscopic management of septic gonitis. MATERIALS AND METHODS: Twenty-five patients were treated for pyogenic gonitis. The duration of symptoms prior to arthroscopic debridement was 10.2 days(range, one to 45 days). The surgical treatment consisted in a arthroscopic irrigation with debridement of infected necrotic tissue, and the medical treatment consisted in a intravenous antibiotics for an average duration of 10.3 days, followed by oral treatment for 3 weeks. RESULTS: The average follow up was 23.7 months(15 to 37). Twenty-three out of 25 patients had regained their activity as painless full range of motion. CONCLUSION: Arthroscopic drainage is a valuable procedure for the treatment of the septic gonitis. Arthroscopic drainage is a method that has proved effective, with minimal morbidity, in attempts to cure septic arthritis of the knee.

BACKGROUND AND OBJECTIVES: Previous studies have demonstrated an association between several single nucleotide polymorphisms and atrial fibrillation (AF). We hypothesized that the phenotypes of AF patients were associated with common AF susceptibility alleles. SUBJECTS AND METHODS: A total of 659 patients (57±9 years, 76% male) with AF who underwent catheter ablation and 659 age, and sex-matched controls were genotyped for the common AF susceptibility alleles rs2200733 and rs6843082 at 4q25, rs2106261 at ZFHX3, and rs13376333 at KCNN3. The phenotypes of AF patients, including electroanatomical characteristics of the left atrium and recurrence after ablation, were compared. RESULTS: The rs2200733 variant allele carriers have larger left atrium volume (128.5±40.7 vs. 113.5±29.2 mL, p=0.020), longer PR interval (185.9±32.6 vs. 174.8±21.9 ms, p=0.018), and higher amplitude of negative P-wave terminal force in Lead V₁ (0.07±0.04 vs. 0.05±0.04 mV, p=0.015) on electrocardiography than those without the variant allele. When the patients were assigned to three groups according to the number of variant alleles (Group A: no variant, n=15; Group B: 1 variant, n=158; Group C: 2 variants, n=439), incremental prognostic value, according to the number of variant alleles, was demonstrated (Log Rank p=0.015). Multivariate Cox regression analysis showed that persistent AF (OR 1.677, 95% CI 1.176-2.381, p=0.004) and the number of variants (OR 1.552, 95% CI 1.099-2.222, p=0.015) were independent predictors for recurrence of AF. CONCLUSION: This study showed the common AF susceptibility alleles at 4q25 and ZFHX3 are associated with electroanatomical characteristics of the left atrium and the clinical outcomes of catheter ablation in Korean patients with AF.

PURPOSE: The purpose of this study was to investigate the frequency, site and characteristics of motion artifact of ascending aorta mimicking dissection. MATERIALS AND METHODS: The authors evaluated postcontrast CT scans of 60 cases in 60 patients without symptoms of aortic dissection or aortic disease. A Toshiba 900S scanner was used, with 1 cm slice thickness and 1 sec scan time. Streak artifacts, and those relating to extra-aortic vascular structure or pericardial effusion were excluded from this study. RESULTS: Crescent-shaped motion artifacts were seen in 54 cases (90%), and occurred from 1 cm to 4 cm above the level of the aortic valve; between men and women, there was no significant difference in frequency. In each case, the artifact was seen at 1 to 5 (mean 2.9) levels. Its pattern was symmetric in 31 of 60 cases (51%), and at 15 other sites, symmetric artifacts were seen between the SVC and ascending aorta. At the margin of the aortic circumference, the direction of the artifact was left anterior-right posterior in 23.9% of cases, and anterior median-posterior median in 20.8%. CONCLUSION: On CT, motion artifact of ascending aorta occurs frequently. Findings relating to location, symmetric pattern and characteristic direction of artifact may be helpful in the differential diagnosis of aortic dissection and aortic motion artifact.

Multiple myeloma can usually be identified by non-traumatic vertebral fracture or signs of recurrent infection. Without these clinical signs, detection is unlikely. We briefly report a case of extraosseous multiple myeloma presenting as repeated intracranial bleeding and relapsing high fever. In doing so, we highlight the importance of subtle changes in laboratory findings. A 67-year-old man presented with spontaneous acute epidural hematoma, and hematoma evacuation was performed at the same site 3 times. A radiologic work-up failed to reveal any osseous lesions and he made a gradual recovery. In the meantime, he suffered unexplained fever up to 39oC despite normal chest and abdominal radiograms. Blood chemistry showed mild leukocytosis, high ESR and CRP, and a slightly elevated globulin. On his 15th hospital day, immunoglobulin studies confirmed the diagnosis of multiple myeloma. He was treated in the ICU for difficult breathing and uncontrolled fever. In spite of intensive critical care, his leukocyte count fell to below 2,000 and he died on postoperative day 28. Apparently normal laboratory and radiologic findings can hamper swift discovery and ultimate management of multiple myeloma. When there is unexplained repeated intracranial bleeding and accompanying fever, the possibility of hidden malignancy should be assessed to avoid delaying or missing treatment.

BACKGROUND: Currently, combined spinal-epidural anesthesia (CSE) is frequently administered, especially in obstetrics and orthopedic surgery. The aim of this study is to determine the appropriate concentration of bupivacaine to use with epidural volume extension that is suitable for total knee replacement during CSE. METHODS: Eighty patients (ASA physical status I and II) scheduled for totalknee replacement were randomly allocated to four groups of 20 patients each: All patients intrathecally received 2 ml of 0.5% hyperbaric bupivacaine. After fixation of spinal anesthesia, the groups received the following treatments. Group S patients received a 10 ml administration of normal saline for 15 min followed by a continuous 10 ml/hr epidural infusion. Group B1 patients received a 10 ml administration of 0.125% bupivacaine for 15 min followed by a continuous 10 ml/hr epidural infusion. Group B2 patients received a 10 ml administration of 0.25% bupivacaine for 15 min followed by a continuous 10 ml/hr epidural infusion. Group B3 patients received a 10 ml administration of 0.5% bupivacaine for 15 min followed by a continuous 10 ml/hr epidural infusion. RESULTS: The incidence of intraoperative movement in group S and group B1 patients were significantly greater than the incidence for group B2 and B3 patients. The incidence of intraoperative pain in group S patients was significantly greater than for patients in any of the other groups. CONCLUSIONS: We conclude that it is necessary to administer more than a 0.25% concentration of epidural bupivacaine load and provide continuous administration after a spinal block during total knee replacement.
