The results of percutaneous radiofrequency rhizotomy of lumbar spinal facets in 46 patients followed at least three months (mean 15 months) are reported and compared with those reported previously. Satisfactory pain relief three months after the procedure was achieved in 36.4 percent of patients without operations and in 41.7 percent of patients with operations other than fusion.No patient had previously undergone fusion.Treatment of low-back pain by using radio-frequency thermocoagulation of spinal facets is a simple, safe, and well-tolerated procedure. It can be used to relief of pain in spite of decreasing rates of success within the follow-up period. 相似文献

Hydatid cysts of central nervous system are rare and comprise only 2% to 3% of all hydatid cysts reported. Orbital localization is very uncommon and has been reported less than 1 % of all hydatid diseases. The primary treatment of hydatid disease is surgical. The most important complication of the surgical treatment is secondary hydatidosis due to spillage of the cyst contents. Because of the difficulties of the orbital localization, total extirpation of the cysts without rupture is almost impossible. Preventing spontaneous rupture of the cysts during surgery and postoperative antihelmintic treatment should be taken into consideration in these cases.This study includes four cases who underwent surgery for orbital hydatid cysts. Radiological characteristics, operative technique and postoperative medical therapy are discussed. 相似文献

Extracorporeal septoplasty is a radical solution for the severely deviated nose. The major problems associated with this
procedure are fixation of the septal cartilage graft and dorsal irregularities. Extracorporeal septoplasty was performed in
combination with open rhinoplasty in 17 patients with severe nasal deformities. In this technique septum was totally removed
through the columellar incision of open rhinoplasty, corrected outside, and replaced as a free ``L' shaped cartilage graft.
The cartilage graft was fixated to the upper lateral cartilages to restore the natural relations of the anatomical structures.
Additional rhinoplastic manipulations were also performed. The follow-up period was up to 18 months. The overall result was
successful in all patients. Nasal deviation did not recur and secondary revisions were not needed for any patient during follow-up. 相似文献

In this study we have investigated the negative influence of CO2 and Nd-YAG laser irradiation on rapid cranial regeneration and whether it has any use in certain types of craniosynostosis.
Twenty-two newborn rats were used in the study. Both CO2 and Nd-YAG laser irradiation, which was applied to free bony edges after, suturectomies, resulted in a significant decrease
in skull regeneration. Histopathological examinations revealed severe degeneration caused by both types of laser energies. 相似文献

Background and aims The aim of this study is to evaluate the predictive accuracy of different scoring systems on surgery for perforated peptic
ulcer referred to an academic department of general surgery in a tertiary reference center.
Patients and methods Seventy-five consecutive patients (Male/female ratio = 64:11; mean age, 44 years; range, 16–85) with perforated peptic ulcer
disease were investigated. Disease severity scores and mortality predictions were calculated using the collected data during
admission. Discrimination and calibration characteristics of each system, namely, the acute physiology and chronic health
evaluation II and III, the simplified acute physiology score II, and the mortality probability models (MPM) II, were determined
by using the area under receiver operating characteristics curve and the Hosmer–Lemeshow goodness-of-fit test, respectively.
Results Among the 75 patients included, there were eight (10.6%) mortalities. All systems had a reliable power of discrimination and
calibration. Among the systems tested, MPM II was the best performing as far as discrimination and calibration characteristics
were considered. The parameters of MPM II system that were related to systemic perfusion of the patient were significantly
positive in patients who died compared to those who survived.
Conclusions MPM II that predicted mortality at admission is better than the other systems in predicting mortality. Results also indicate
the importance of maintenance of systemic perfusion of the patient at the early phases of peptic ulcer perforation. 相似文献

Since it covers the lateral wall of the mastoid air system, the suprameatal triangle is of importance to otologic surgeons
during mastoidectomy. Because of this clinical importance, topographic anatomy of the suprameatal spine and depression was
studied on Anatolian skulls. In all, 363 male and 231 female skulls were studied. The most prevalent type of suprameatal spine
resembled a crest and was found in both sexes on the right (77.6%) and left (80%) sides. The absence of a suprameatal depression
was significantly higher in females (right 9.1%; left 8.7%) than in males (right 1.7%; left 2.5%). Suprameatal depressions
were mostly shallow in female subjects, but were mostly observed in males to be at a medium depth or deep.

Either oral, intravenous or subcutaneous 1.25 (OH)2 cholecalciferol is used in the therapy of hyperparathyroidism, which is a serious complication in patients on haemodialysis.
We studied a total of 30 patients (10 women and 20 men) and divided them into two groups depending on the different types
of dialysis membranes used. In the poly sulfone group, mean age was 43.7±0.97 years and the average dialysis period lasted
29.9±1.23 months. For the 15 cases in which we used cuprophane membrane the mean age was 40.2±1.31 years and the average dialysis
period lasted 16.2±0.86 months. The calcium level of the dialysate in both groups was 1.5 mmol/l.
According to the study protocol, the determined oral calcitriol dose was 0.07 mg/kg and it was administered intermittently.
After one month on high dose calcitriol therapy, treatment was continued with a maintenance dose of 0.03 mg/kg for a further
six months. As a phosphate binding agent, daily 3 g calcium carbonate was administered.
Before starting this treatment protocol, patients went on a 1 mg/day calcitriol therapy, although the mean PTH level was 424.63
pg/ml and the mean serum alkaline phosphatase level was 290.2 U/l. During the pretreatment period, levels of PTH, alkaline
phosphatase, ionized calcium, and total calcium remained significantly within normal limits as a result of the new therapy
protocol applied.
PTH and phosphorus clearance rates were compared in the patient groups in which different dialysis membranes had been used.
PTH and phosphorus clearances were 15.2±3 ml/min and 239.1±19.2 ml/min, respectively, in the polysulfone membrane group, and
1.1±0.3 ml/min and 112.8±9.88 ml/min, respectively, in the cuprophane membrane group (p<0.05). 相似文献

Three patients who had chronic osteomyelitis of the calcaneus were treated with radical debridement of all involved soft tissue and bone and obliteration of dead space with a pull-through abductor hallucis brevis muscle flap. Two patients had calcaneal osteomyelitis without soft tissue loss resulting from previous comminuted calcaneal fractures while a third patient had a large soft tissue defect and calcaneal osteomyelitis resulting from a destructive infection. All of the patients had undergone several surgical procedures for treatment of the osteomyelitis with histories ranging 18 months to 30 months. Following treatment with the pull-through muscle flap there has been no recurrence over the longterm (>two years). We believe that radical removal of all contaminated tissue and immediately coverage with a muscle flap provides an effective single stage treatment of chronic calcaneal osteomyelitis. 相似文献
