From Jan. 1987 to May 1994, we carried out cementless total hip arthroplasties using hydroxyapatite-coated Omnifit system, and among these, 63 cases in 49 patients were followed up more than 24 months. The average Harris Hip Score was 46.3 points preoperatively, 95.4 points at POD 1 year and 96.2 points at POD 2 years. Two patients (3%) complained thigh pain at POD 2 years. On the radiologic findings, endosteal bone formation was noted in 34 cases (53,9 %), radiolucent lines were seen at the non-coating region of distal stem in 41 cases (65.3%), which were less than 2mm and not progressive. Cortical hypertrophy was noted in 5 cases (8.4%), and calcar atrophy was observed in 31 cases (49 %).

Transient osteoporosis of the hip is a self-limited condition of uncertain etiology and pathogenesis that affects young and middle aged adults. Even its clinical features are similar to the features of osteonecrosis the prognosis and clinical end result are quite different. So differential diagnosis between the two is very important. We present a case of transient osteoporosis of the hip in middle aged man, which was completely reeovered after conservative treatment.

BACKGROUND: Methemoglobinemia(MetHb) induced by dapsone overdose is not uncommon in Korea, especially in rural area. For treatment of dapsone-induced methemoglobinemia, methylene blue(MB) and activated charcoal(AC) should be used. To date, no reports have compared the amount of MB used between MB alone with MB & AC combined group(MB+AC). And also between moderate (MetHb<35%) and severe (MetHb>35%) intoxicated group defined by initial MetHb level. Authors hypothesized that less amount of MB can be used if MB and AC was used together and larger amount of MB is necessary to reduce MetHb level to asymptomatic level in severely intoxicated group. METHODS: From Jan 1990 to Dec 1996, a total of 54 patients who received treatment for dapsone intoxication were subject of study, The study was done retrospective chart analysis for initial MetHb level, total amount of MB and AC. Wilcoxon rank sum test and Chi-sqiare test was used to compare the total dosage of MB used for each group. Linear regression analysis was used between initial MetHb and the total amount of MB. Results were considered statistically significant when p<0.05. RESULTS: For MB alone and MB+AC group, the differences in total amount of MB used were statistically significant with mean dosage of 7.14+/-1.1mg/kg and 4.28+/-0.7mg/kg, respectively. And total amount of MB used between moderate and severe intoxicated group, the differences were statistically significant with mean dosage of 5.16+/-1.1mg/kg vs. 10.98+/-1.9mg/kg, respectively. There was significant correlation between initial MetHb level (X) and the amount of methylene blue (Y), Y=0.3X-2.42 (r2=0.41, p=0.0001) in MB alone, Y=0.186X-1.95(r2=0.21, p=0.034) in MB+AC respectively. CONCLUSION: For methemoglobinemia induced by dapsone, total amount of MB can be reduced especially in severe Intoxicated group if AC use was combined in treatment modality. There was significant correlationship between initial MetHb level and total amount of MB used.

5.PROP1 Gene Analysis in Korean Children with Hypopituitarism.

Journal of Korean Society of Pediatric Endocrinology 2009;14(1):52-59
PURPOSE:Mutations of the PROP1 (Prophet of PIT1) gene lead to combined pituitary hormone deficiency (CPHD), which is characterized by a deficiency of growth hormone (GH), thyroid stimulating hormone (TSH), luteinizing hormone (LH)/follicle stimulating hormone (FSH), prolactin (PRL) and adrenocorticotropic hormone (ACTH). We studied the PROP1 mutations in Korean children with hypopituitarism. METHODS:Twelve patients with congenital hypopituitarism were recruited from the Ajou University Hospital, Korea. The pituitary phenotype ranged from isolated growth hormone deficiency (IGHD) to CPHD. Clinical data, including endocrine and neuroradiological data were obtained from the medical records, and the DNA was collected and screened for mutations within PROP1 using polymerase chain reaction (PCR). The PCR products were sequenced directly. RESULTS:Nine patients had abnormal pituitary gland and three patients showed normal pituitary gland in magnetic resonance imaging (MRI). Endocrinologically, seven patients had IGHD and five had CPHD. Three of CPHD had GHD and hypogonadotrophic hypogonadism and the other two had GHD, central hypothyroidism, and ACTH deficiency. We identified no mutations in the PROP1 gene. However, three known polymorphisms were identified: The 27T->C (Ala9Ala) and the associated IVS1+3A->G in exon 1 were found in 25% of patient alleles sequenced. The 424G->A (Ala142Thr) in exon 3 change was identified in 4% of those sequenced. CONCLUSION:This study corresponds to the previous reports that PROP1 mutations are rare in sporadic cases of CPHD. The low mutation frequency in Korean patients may be due to ethnic-specificity or other candidate genes causing this disease. It is necessary to study PROP1 gene and the involved genes in more Korean patients.

It has been postulated that seminal plasma contains a potent immunosuppressive factor(s) which play a critical role h preventing sensitization of females to sperm antigens after insemination. It has been shown that human seminal plasma (HuSePl) inhibited phytohemagglutinin(PHA) and Concanavalin A(ConA) induced blast transformation of normal peripheral blood lymphocytes. To analyze protein fractions of HuSePl and to observe suppression of cell-mediated immune response by each fraction, the authors performed the Sephadex G-100 chromatography and the lymphocyte transformation with parameters of purified PHA(PHA-P) and pokeweed mitogen(PWM) stimulation test. The results were as follows; 1. Sephadex G-100 chromatography of HuSePl yielded five fractions(Fr. 1-5). 2. The molecular weight of each fraction, assessed by sodium dodecyl sulfate polyacrylamide gel electrophoresis(SDS.PAGE), was from 14,000 daltons(D) to more than 85,000 D in Fr. 1, 42,000 D and 33,000 D in Fr. 2, 43,000 D in Fr. 3, 20,000 D in Fr. 4 and 19,000 D in Fr. 5. 3. The mean percentages .of suppression in PHA-P stimulation test by fractions isolated from HuSePl in male (n=I3) were 59.8+10.1% in Fr. 1, 59.5+23.0% in Fr. 2, 84.2+9.4% in Fr. 3, 60.9+/-2l.4% in Fr. 4, 49.4+/-23.2% in Fr. S(F=6.=8, P <0.01) and in female (n=13) were 64.6+/-11.7 % in Fr. 1, 65.4+13.1% in Fr. 2, 82.9+9.2% in Fr. 3, .55.4+21.5% in Fr. 4, 59.2+/-26.0% in Fr. 5(F=4.76, P <0.01). 4. The mean percentages of suppression in PWM stimulation test by fractions isolated from HuSePl in male (n=11) were 15.8+/-17.1% in Fr. 1, 45.1+18.6% in Fr. 2, 80.4+2.7% in Fr. 3, 61.7 + 4.2 % in Fr. 4, 63.5+/-12.8% in Fr. 5(F=38.91, P<0.01) and in female (n=11) were 9.5+/-15.3% in Fr. 1,32.9+/-20.5% in Fr. 2, 78.7+4.5% in Fr. 3,59.9+/-10.0% in Fr. 4, 55.3+15.2% in Fr. 5(F =39.65, P <0.01). 5. The sex difference was not significant in PHA and PWM stimulation test with each fraction (P>0.05). The results revealed that the Fr. 3 has the strongest suppressive effect on lymphocyte transformation activity and these observations support the concept that a local immune response against sperm in the female reproductive tract is actively suppressed by a component in seminal plasma.
