The writers performed Sbarbaro type total hip replacement arthroplasty on two cases with degenerative arthriris of both hips complicated by avascular necrosis of the femoral head. In each case, the procedure was carried out on the worse hip, while in one case a standard femoral head prosthesis was inserted to the less severely involved hip. The Sbarbaro type prosthesis consists of a modified Austin Moore head component and an acetabular cup with tynes that fix the metal to the acetabulum and does not require the use of cement. The initial results in both cases, evaluated by the method of D'Aubigne and Postel, are as follows; Grade 5 for pain(pain both slight or intermittent), Grade 5 for motion(very good or 161 to 210 degrees), and Grade 5 for ability to walk(very good; no cane or crutch but a slight limp).

Laboratory and clinical evidence indicates a potentially important role for barbiturates in the management of brain injury and intracranial hypertension. The present report describes our experience with the thiopental and mannitol therapy in 30 consecutive patients who were over 20mmHg of intracranial pressure(ICP) in severe head injuries and the other comatous conditions. The anothers have analyzed the effects of thiopental on outcome in comatous 30 patients by continuous monitoring of ICP. High dose barbiturate therapy was induced with an intravenous bolus of thiopental, 40mg/kg and the infusion of barbiturates intermittently continued until control of the ICP(below 20mmHg) was obtained. In those patients responding to thiopental, the daily mannitol requirement was reduced from 3.5 to 0.5mg/kg/day. Our overall results are presented; 1) In patients with intracranial mass lesions only very high ICP(>40mmHg) on barbiturate management was significantly associated with a poor neurological deficit and outcome from injury, while the patients with any increased in ICP above 20 to 29mmHg was associated with a moderate neurological disability and better outcome with thiopental and mannitol treatment. 2) In patients with surgical mass lesion ICP between 20 to 29mmHg was significantly associated good neurological picture and outcome, but the patients in ICP above 40mmHg, had a 75% motality. 3) Decreases in ICP over 20mmHg were seen in 75%of the patient who had managed with thiopental and mannitol. 4) Thiopental responders have returned to a good recovered and minimal deficit, but thiopental nonresponsiveness was associated with a completely unfavorable outcome:5 deaths, 1 vegetative survior.

The adenoid cystic carcinoma in the orbit is rare, but is the most common in the malignancy of the orbit. The clinical signs are proptosis with displacement of the globe downward and inward, limitation of ocular movements and diplopia. The diplopia and ocular pain is due to the tumor metastasis to the extraocular mescle and nerve sheath. The authors have experienced a case of adenoid cystic carcinoma in the right orbit in a 72-year-old man.

BACKGROUND: We investigated the relationship between endothelial dysfunction and diabetic retinopathy (DR) in patients with type 2 diabetes. METHODS: We used a cross-sectional design to examine 167 patients with type 2 diabetes mellitus. All patients underwent biochemical and ophthalmological examination. We assessed endothelial dysfunction by a flow-mediated vasodilation method of the brachial artery. Changes in vasodilation (flow-mediated vasodilatation, %FMD) were expressed as percent change over baseline values. RESULTS: The mean+/-standard deviation of patient age was 54.1+/-8.6 years. The %FMD was significantly lower in patients with DR than without DR. The prevalence of retinopathy decreased across increasing tertiles of %FMD. After adjusting for patients' age, sex, diabetes duration, use of insulin, use of antihypertensive, antiplatelet, and lipid lowering medications, systolic blood pressure, fasting plasma glucose, 2-hour plasma glucose, glycated hemoglobin, and urinary albumin excretion, participants with a reduced %FMD were more likely to have DR (odds ratio, 11.819; 95% confidence interval, 2.201 to 63.461; P=0.004, comparing the lowest and highest tertiles of %FMD). CONCLUSION: Endothelial dysfunction was associated with DR, which was most apparent when the endothelial dysfunction was severe. Our study provides insights into the possible mechanism of the influence of endothelial dysfunction on the development of DR.

Anomalous origin of left coronary artery from pulmonary artery (ALCAPA) is a rare congenital cardiovascular anomaly. The mortality rate among infants and children without operation has been eighty to ninety-five percents and few patients survive till teen-age or adulthood. This anomaly was detected during elective coronary angiogram in a 32 year-old female patient with atypical chest pain. Reversible ischemia was demonstrated on myocardial 201Tl-SPECT. Coronary angiogram revealed anomalous origin of left coronary artery from pulmonary artery.

Cluster headache attacks can be successfully treated with oxygen. We report four patients with episodic cluster headache were treated with oxygen therapy from one or two oxygen concentrators. Oxygen therapy with two oxygen concentrators seems to be effective in reduction or cessation of pain of cluster headaches. Patients expressed excellent satisfaction to oxygen therapy with two oxygen concentrators. Oxygen concentrators can be considered as an effective and safe alternative of oxygen cylinder for patients with cluster headache.

Background: and Purpose Oxygen treatment is the first-line acute treatment for cluster headaches (CHs), but this can be impeded by insurance coverage and oxygen-tank maintenance. Oxygen concentrators filter nitrogen from ambient air to produce oxygen-rich gas, and can therefore be an alternative to conventional oxygen therapy using a tank. We investigated the effectiveness and safety of using two home oxygen concentrators and compared them with using oral zolmitriptan for the acute treatment of CHs. Methods: Forty patients with episodic CHs in an active cluster period were enrolled in this randomized, crossover, multicenter study. Two attacks during the cluster period were treated using oxygen delivered by connecting two home oxygen concentrators, whereas the other two attacks were treated using oral zolmitriptan (5 mg) in a random sequence. The primary endpoint was substantial pain reduction (0 or 1 on a five-point rating scale from 0 to 4 points) at 15 min after treatment. Results: In total, 125 attacks among 32 patients were randomized and treated (63 attacks using oxygen and 62 using zolmitriptan) according to the study protocol. More attacks treated using oxygen reached the primary endpoint than did those treated using zolmitriptan (31.7% [20/63] vs. 12.9% [8/62], p=0.013). After 30 min, 57.1% of the patients who received oxygen and 38.7% who received zolmitriptan reported pain relief (p=0.082). All patients treated using oxygen reported an improvement in pain, and 61.3% preferred oxygen while only 9.7% preferred zolmitriptan. No adverse events occurred during the oxygen treatment. Conclusions Oxygen treatment administered using two home oxygen concentrators resulted in better pain relief than oral zolmitriptan in patients with episodic CHs. Our results suggest that home oxygen concentrators are capable of efficiently supplying oxygen in a similar manner to using an oxygen tank.

BACKGROUND: Vascular endothelial growth factor (VEGF) plays an important role in angiogenesis, including stimulating the proliferation and migration of vascular smooth muscle cells (VSMCs). It has been known that diabetes is associated with accelerated cellular proliferation via VEGF, as compared to that under a normal glucose concentration. We investigated the effects of selective blockade of a VEGF receptor by using anti-Flt-1 peptide on the formation and hyperplasia of the neointima in balloon injured-carotid arteries of OLETF rats and also on the in vitro VSMCs' migration under high glucose conditions. MATERIAL AND METHOD: The balloon-injury method was employed to induce neointima formation by VEGF. For 14 days beginning 2 days before the ballon injury, placebo or vascular endothelial growth factor receptor-1 (VEGFR-1) specific peptide (anti-Flt-1 peptide), was injected at a dose of 0.5 mg/kg daily into the OLETF rats. At 14 days after balloon injury, the neointimal proliferation and vascular luminal stenosis were measured, and cellular proliferation was assessed by counting the proliferative cell nuclear antigen (PCNA) stained cells. To analyze the effect of VEGF and anti-Flt-1 peptide on the migration of VSMCs under a high glucose condition, transwell assay with a matrigel filter was performed. And finally, to determine the underlying mechanism of the effect of anti-Flt-1 peptide on the VEGF-induced VSMC migration in vitro, the expression of matrix metalloproteinase (MMP) was observed by performing reverse transcription-polymerase chain reaction (RT-PCR). RESULT: Both the neointimal area and luminal stenosis associated with neointimal proliferation were significantly decreased in the anti-Flt-1 peptide injected rats, (0.15+/-0.04 mm2 and 36.03+/-3.78% compared to 0.24+/-0.03 mm2 and 61.85+/-5.11%, respectively, in the placebo-injected rats (p<0.01, respectively). The ratio of PCNA(+) cells to the entire neointimal cells was also significantly decreased from 52.82+/-4.20% to 38.11+/-6.89% by the injected anti-Flt-1 peptide (p<0.05). On the VSMC migration assay, anti-Flt-1 peptide significantly reduced the VEGF-induced VMSC migration by about 40% (p<0.01). Consistent with the effect of anti-Flt-1 peptide on VSMC migration, it also obviously attenuated the induction of the MMP-3 and MMP-9 mRNA expressions via VEGF in the VSMCs. CONCLUSION: Anti-Flt-1 peptide inhibits the formation and hyperplasia of the neointima in a balloon-injured carotid artery model of OLETF rats. Anti-Flt-1 peptide also inhibits the VSMCs' migration and the expressions of MMP-3 and MMP-9 mRNA induced by VEGF under a high glucose condition.

BACKGROUND AND OBJECTIVES: Glucose-insulin-potassium (GIK) fluid infusion may improve the myocardial energy metabolism in the ischemic condition. A prospective randomized clinical trial was designed to determine whether a GIK fluid infusion can reduce the ventricular remodeling in acute myocardial infarction. SUBJECTS AND METHODS: For the patients with acute myocardial infarction, during thrombolytic therapy with urokinase, GIK fluid (26% glucose 1000 mL, 50 IU insulin, and 80 mmol KCl) was administered for 24 hours. The ventricular volumes and function were evaluated by echocardiography during the admission period, at 6 months and at 12 months following discharge. RESULTS: This trial was done prospectively for 2 years in 73 patients; the GIK group included 41 patients and the control group included 32 patients. The median value of "the pain to door time" was 195 minutes in the GIK group and it was 120 minutes in the control group (p=NS). The wall motion score was 1.52+/-0.39 in the GIK group and it was 1.39+/-0.35 in the control group. The left ventricular volumes, ejection fractions, cardiac indices and the globular indices showed no significant difference between the two groups. The side effects of the GIK fluid were mild phlebitis in 6 patients (14.6%) and congestive heart failure in 5 patients (12.2%). CONCLUSION: This trial could not verify the beneficial effects of administering GIK fluid on the ventricular remodeling after acute myocardial infarction. The limitations of this trial were as follows: "the pain to door time" was too long and the severity of the myocardial infarction was mild. Low rates for the echocardiogrphy follow-up and the randomization failure in a few patients were also noted.
