Background
Minimally invasive techniques for hallux valgus have been widely used to treat mild to moderate hallux valgus deformities. The purpose of this study was to evaluate the clinical and radiographic outcomes of distal linear metatarsal osteotomy (DLMO), which is one of the minimally invasive techniques, for severe hallux valgus.Methods
95 patients (141 feet) with severe hallux valgus underwent DLMOs. Lateral soft tissue release (LSTR) was performed at the same time for the cases selected by an original manual test. The satisfaction level, the Japanese Society of Surgery of the Foot (JSSF) hallux scale score, and weight-bearing radiographs of the foot were assessed preoperatively and after more than 24 months. In addition, the clinical and radiographic outcomes were compared among three groups divided by the kind of LSTR: no LSTR; manual correction; and open release through skin incision.Results
Although the first metatarsal bone was significantly shortened, dorsiflexed, and elevated on postoperative radiographs, the rate of satisfaction was 87.2% (123/141), and the mean JSSF hallux scale score improved significantly from 60.4 (44–73) to 90.4 (65–100). The mean hallux valgus and intermetatarsal angles also improved significantly from 45.5° (40.0–60.0°) to 10.3° (?28.0–40.9°) and from 19.9° (14.0–28.7°) to 8.3° (?1.6–18.5°), respectively. Delayed union (18 feet), metatarsalgia (16 feet), recurrence (22 feet), and hallux varus (22 feet) were observed, and they were more obvious in DLMO combined with open release through a skin incision.Conclusions
DLMO combined selectively with LSTR is an effective procedure for correcting severe hallux valgus. However, the indication for open release with DLMO should be considered carefully. 相似文献73.

This study was undertaken to determine the value of Doppler ultrasonography in the early evaluation of therapeutic efficacy
of hepatocellular carcinoma after transcatheter arterial embolization (TAE). Fifty-two nodules in which tumor vascularity
had been detected by Doppler ultrasonography before TAE were examined in 41 patients. Doppler signals were evaluated 1 week
after TAE, and the results were compared with tumor vascularity as determined by dynamic magnetic resonance imaging (dynamic
MRI), which was used as the gold standard. The sonographic signal disappeared in 41 (79%) of the 52 nodules and remained in
11 (21%). All nodules in which intratumor vascularity had been detected showed positive stain to dynamic MRI. Four of 41 nodules
in which the sonographic signal disappeard showed positive stain on dynamic MRI. The Sensitivity of Doppler ultrasonography
was 73%; specificity, 100%; and accuracy, 92%. Flow signal in deeply (≥5 cm) located small (<3 cm) nodules tended to be more
difficult to detect. We conclude that Doppler ultrasonography warrants use after TAE in the early evaluation as a specific
and noninvasive imaging technique. 相似文献

SYNOPSIS
Two patients with paranasal sinusitis, who showed cluster headache like symptoms rather than typical sinusitis symptoms, are reported. A possible mechanism of the cluster headache like symptoms is discussed. The importance of paranasal radiological study of patients with cluster headache like symptoms is emphasized. These cases seem to support a neuronal pathogenesis of the cluster headache syndrome. 相似文献

In migraine, the role of platelets is regarded as an important factor. We investigated plasma beta-thromboglobulin (BTG), platelet factor 4 (PF4), and 5-hydroxytryptamine (5-HT) in migraine patients and muscle contraction headache (MCH) patients during headache-free periods. The mean values of the plasma BTG, PF4, and 5-HT concentrations in the migraine group and the MCH group were significantly higher than those in healthy controls. The mean value of the plasma BTG concentration was significantly higher in the migraine group than in the MCH group, but the differences in the mean plasma PF4 and 5-HT concentrations between the two groups were not significant. Continuous platelet activation exists in both MCH patients and migraine patients. From the biochemical point of view, we have provided evidence for a similarity between migraine and MCH. 相似文献

The microbicidal activities of superoxidized water (electrolysed strong acid water [ESAW] or electrolysed weak acid water [EWAW]), ozonated water, 0.05% chlorhexidine and 2% glutaraldehyde were tested against seven strains of clinical micro-organism isolates. Following incubation of bacterial suspensions in ESAW and EWAW for 10 s, the number of micro-organisms was reduced below the detection limit. The microbicidal activities of ESAW and EWAW were similar to that of glutaraldehyde, and superior to ozonated water and 0.05% chlorhexidine. The microbicidal activities of ESAW, EWAW and ozonated water were markedly diminished in the presence of albumin. Microbial contamination of upper gastrointestinal endoscopes was detected after 90 endoscopic procedures, but treatment of the endoscope with ESAW, EWAW or ozonated water eradicated the microbes. These results indicate that ESAW and EWAW are effective disinfectants after mechanical cleaning of upper gastrointestinal endoscopes, and can, therefore, be used in the endoscopy unit. 相似文献

The aim of the present study was to investigate whether CYP2C19 polymorphism status and gastric emptying are related to healing in patients with gastric ulcers. We studied the CYP2C19 status in seven patients with proton pump inhibitor (PPI)-resistant ulcers, 21 with PPI-sensitive ulcers and 46 healthy volunteers using polymerase chain reaction restriction fragment length polymorphism to detect CYP2C19m1 mutation in exon 5 and CYP2C19m2 mutation in exon 4. Gastric emptying was evaluated using the 13C-acetate breath test. The frequency of phenotypes, indicated by genotypes, did not differ significantly between the three patient groups. The peak time of 13C excretion in patients with PPI-resistant ulcers was significantly longer than that of patients with PPI-sensitive ulcers and healthy volunteers. Our results suggest that rate of gastric emptying, but not CYP2C19 polymorphism, is likely to be an important factor in the delayed healing of patients with PPI-resistant gastric ulcer. 相似文献

Klinefelter syndrome is a condition in which a male patient has one Y chromosome and one or more extra X chromosomes. It is the most common sex chromosome disorder. Klinefelter syndrome is distinguished by many clinical features, such as infertility, high gonadotropin and low testosterone levels, increased height, and sparse body and facial hair. We report the case of a 32‐year‐old man who visited our hospital complaining of male infertility. Semen analysis showed azoospermia, and chromosomal analysis revealed a 47,XY,i(X)(q10) karyotype, which is a rare variant of Klinefelter syndrome. No spermatozoon was found on microdissection testicular sperm extraction, and the testis biopsy histology showed only Sertoli cells and hyalinised seminiferous tubules. 47,XY, i(X)(q10) has an additional isochromosome made of the long arm of the X chromosome, which shares some features of classical Klinefelter syndrome in many aspects, but patients are usually shorter than average height and have normal intelligence. In addition, to the best of our knowledge, no successful sperm extractions from 47,XY, i(X)(q10) patients were reported in the literature. The reports of patients who have undergone microdissection testicular sperm extraction are very rare. Further reports and studies of this chromosomal abnormality are needed. 相似文献

Chest wall tumors are uncommon, but intercostal hemangioma is even more so: There have been only a handful of reports on it
to date. We report on a 32-year-old man with a left-side chest wall mass detected on a chest roentgenogram and computed tomography
scans. The tumor was completely resected by means of video-assisted thoracic surgery. Two years after the surgery, the patient
is doing well with no evidence of recurrence. 相似文献
