BACKGROUND: In our previous report, we observed the increaseed epidermal glucose concentrations and decreased hexokinase actiuities of diabetic patients which were ciimpared to those of normal individuals. And we considered that, there were some derrangement of lipid metabolism and glycolysis of diabetic epidermis. OBJECTIVES: This study wns planed to prove the above possible changes of lipid metabolism and glycolysis of diabetic epidermis. METHODS: The epidermal enzymatic activties of glucose-6-phophate dehydrogenase(G6PDH), phosphofructokinase(PFK), 1-glycerophosphate dehydrogenase(GOPDH) and b-hydroxybutyryl CoA dehydrogenase(HBDH) were assayed in the skin samples obtained friom diabetic patients and normal individuals by the fluorometric: method. RESULTS: Teh epidermal PFK activities of diabetic patients were decreased(3.49+1.35(mmole/hr/kg dry weight)) compared to that of normal individuals(5.00+0.56(mmcle/hr/kg dry weight))(p<0.05). The epidermal HBDH activities of diabetic patients were decreised(0.28+0.10(mole/hr/kg dry weight)) compared to that of normal individuals(0.49+0.20(mole/hr/kg dry weight)(p<0.01). The mean epidermal G6PDH activity of diabetic patients was decreasec. compased to that of normal individuals, but there was no statisical significance. The mean epidermal 3OPDH activittes of diabetic patients and normal individual; showed no significant difference. CONCLUSION: We consider that the decreased epidermal HBDH actiities of diabetic patients can decrease keton body formatiori, and the abnormal glycolysis can exist in the diabetic epidermis because the decreased enzymatic activities of diabetic epidermal PFK may decrease the velocity of glycolysis.

BACKGROUND AND OBJECTIVES: The present study aimed to compare receptive and expressive language development in children who have undergone simultaneous bilateral cochlear implantation (SCI) and those who have undergone bimodal stimulation (unilateral CI+ hearing aid). SUBJECTS AND METHOD: In a retrospective analysis of clinical data, 15 pediatric patients who have received SCI and nine patients who have received bimodal stimulation (BM group) were enrolled. CI was performed for all patients at 24 months of age. Category of Auditory Performance (CAP) scores, Infant-Toddler Meaningful Auditory Integration Scale (IT-MAIS) scores, and developmental quotients (DQ) for expressive and receptive language were compared between the groups at 12 month of follow-up. The Percentage of Consonants Correct (PCC) of children evaluated at 4 years old was also compared. RESULTS: At 12 months of follow-up, significantly greater improvements in CAP scores (Δ4.25±0.5) were noted in the SCI group compared to the BM group (Δ3.56±0.88, p=0.041). Significantly greater improvements in IT-MAIS scores were also noted in the SCI group (Δ36.17±4.09) than in the BM group (Δ30.17±2.91, p=0.004). The DQ of receptive language was higher in the SCI group than in the BM group (87.6±15.4% vs. 75.5±12.0%, p=0.023) at 12 months of follow-up. Moreover, early SCI was associated with better receptive language skills. PCC index of children at 4 years old was higher in the SCI group than in the BM group (88.5±13.2% vs. 62±15.8%, p=0.014). Earlier SCI was associated with even greater improvements. CONCLUSION: Bilateral SCI is associated with significant improvements in language development when compared with bimodal stimulation. Earlier SCI was associated with better outcomes.

Chronic rhinosinusitis (CRS) is a complex inflammatory disorder that affects between 2% and 16% of adults in the United States, with estimated healthcare costs between 4 and 12 million USD. Viruses are a common etiologic factor for URIs, are frequently identified in the sinuses of patients with CRS, and trigger CRS exacerbations. Therefore, investigating the role of viruses provides an opportunity to identify their role in the pathogenesis of CRS. In this review, we identified the viruses frequently isolated in patients with CRS, as well as their associated immunologic responses and contributions to inflammation. Rhinovirus, parainfluenza virus, influenza virus, and respiratory syncytial virus are the viruses commonly found in patients with CRS. This information allows us to target pathways early in the pathogenesis of CRS, thereby playing a significant role in slowing the progression of this chronic disease.

The loss of neuronal cells in the central nervous system may occur in many neurodegenerative diseases. Alzheimer's disease is a common senile disease in people over 65 years, and it causes impairment characterized by the decline of mental function, including memory loss and cognitive impairment, and affects the quality of life of patients. However, the current therapeutic strategies against AD are only to relieve symptoms, but not to cure it. Because there are only a few therapeutic strategies against Alzheimer's disease, we need to understand the pathogenesis of this disease. Cell therapy may be a powerful tool for the treatment of Alzheimer's disease. This review will discuss the characteristics of Alzheimer's disease and various available therapeutic strategies.

Etretinate(Ro 10-9359), an aromatic analogue of vitamin A acid, has been known to be effective in the treatment of psoriasis, Darier's disease, pityriasis rubra pilaris, ichthyosis, and palmoplantar keratoderma when administered orally. In this experiment, we compared the therapeutic and side effects between a group with high dose therapy(initially 75mg of etretinate a day) and an another group with low dose therapy(initially 40mg of etretinate a day). We also observed whether the pretreatment followed by combined treatment with vitamin E could potentiate the therapeutic effect as well as reduce the side effects of oral etretinate. This experiment comprised 102 moderate to severe psoriatic patients. The following results were obtained from this experiment. 1. Fifty-six among 92 patients(61%) who were treated with etretinate for more than 4 weeks showed good to excellent therapeutic effect. 2 The high dose therapy was more effective, but showed more side effects than low dose therapy. 3 Vitamin E did not potentiate the effect of etretinate. In low dose therapy, the pretreatment followed by combined treatment with vitamin E showed a tendency to reduce the side effects of etretinate.

A 18-year-old male soccer player had painful triggering and occasional locking of the great toe caused by entrapment of the flexor hallucis longus tendon within the flexor sheath posterior to the right medial malleolus. After other treatment modalities failed, the condition was relieved by a surgical procedure that removed the nodule on the flexor hallucis longus tendon and the ganglion under flexor retinaculum. Tendon rupture was not found, although there was tendinitis.

PURPOSE: We assessed the results of open treatment of anterior impingement syndrome of the ankle in elite level soccer players and concomitant injuries were idenfied. MATERIALS AND METHODS: We retrospectively reviewed twenty one elite level soccer players diagnosed with anterior impingement syndrome who underwent open debridement between January 1997 and January 2002. All were men and the mean age at the operation was 21 years (range 16 to 27). The mean follow-up duration was 31 months (13 to 71). Concomitant abnormalities were idenfied through physical examination, bone scan and MRI. On a preoperative lateral radiograph, patients were classified according to McDermott's stage. Anteromedial or anterolateral approach was used at the operation and osteophyte was removed with osteotome and rongeur. When chronic ankle instability was accompanying, we performed Modified Brostrom-Gould procedure and for osteochondral lesion, multiple drilling was applied. The Ogilvie-Harris scoring system was used as a clinical scale to evaluate pain, swelling, stiffness and limitation of activity. The results were scored as excellent (15 to 16 points), good (13 to 14) and otherwise unsatisfactory. The time to return to full activity including sports activity was determined. RESULTS: Eighteen of twenty one patients had an excellent outcome. Three patients were graded unsatisfactory and two of them abandoned their career due to the persistence of residual pain. Concomitant abnormalities were found including twelve cases of chronic ankle instability, three cases of osteochondral lesion and two cases of flexor hallucis longus tendinitis. CONCLUSION: Open debridement was successfully applied to the elite level soccer player with anterior impingement syndrome of the ankle. Considerable coexistence of other abnormalities such as chronic ankle instability may encourage us to consider additional operative procedure.

BACKGROUND: Improvement in antiviral therapies have been accompanied by an increased frequency of non-Acquired Immune Deficiency Syndrome (AIDS) defining malignancies, such as glioblastoma multiforme. Here, we investigated all reported cases of human immunodeficiency virus (HIV)-positive patients with glioblastoma and evaluated their clinical outcomes. A comprehensive review of the molecular pathogenetic mechanisms underlying glioblastoma development in the setting of HIV/AIDS is provided. METHODS: We performed a PubMed search using keywords “HIV glioma” AND “glioblastoma,” and “AIDS glioma” AND “glioblastoma.” Case reports and series describing HIV-positive patients with glioblastoma (histologically-proven World Health Organization grade IV astrocytoma) and reporting on HAART treatment status, clinical follow-up, and overall survival (OS), were included for the purposes of quantitative synthesis. Patients without clinical follow-up data or OS were excluded. Remaining articles were assessed for data extraction eligibility. RESULTS: A total of 17 patients met our inclusion criteria. Of these patients, 14 (82.4%) were male and 3 (17.6%) were female, with a mean age of 39.5±9.2 years (range 19–60 years). Average CD4 count at diagnosis of glioblastoma was 358.9±193.4 cells/mm3. Tumor progression rather than AIDS-associated complications dictated patient survival. There was a trend towards increased median survival with HAART treatment (12.0 vs 7.5 months, p=0.10) CONCLUSION: Our data suggests that HAART is associated with improved survival in patients with HIV-associated glioblastoma, although the precise mechanisms underlying this improvement remain unclear.

Observational studies and laboratory research support cardioprotective effects of menopausal hormone treatment (MHT). However, cardioprotective effects of MHT were not confirmed by randomized clinical studies that were made up of subjects who were well-beyond the time of menopausal symptoms and were of advanced chronological age when they began hormone treatment (HT). The differences in study outcomes most likely reflect age-related differences in cardiovascular risk factors such as hypertension and metabolic syndromes. As well, data from the randomized clinical trial (RCT)s confirmed the presence of actual cardiovascular disease (CVD) in many of the RCT subjects prior to beginning HT. Therefore, beginning MHT early seems crucial since older women are at greater risk for the presence of risk factors and sub-clinical CVD. Older women also are possible targets of hormonally related thrombosis because of their underlying vascular disease. The need for early prophylaxis is convenient since most women seek treatment for symptoms within the first few years of menopause. This review addresses issues regarding optimization of the initiation of MHT for cardioprotection.
