A comparison of pre-emptive analgesic efficacy of diflunisal and lornoxicam for postoperative pain management: a prospective, randomized, single-blind, crossover study.

Diflunisal and lornoxicam are currently available non-steroidal anti-inflammatory drugs (NSAIDs) that have been shown to be effective to various degrees in pain relief when administered either pre-emptively or postoperatively. The pre-emptive analgesic efficacy of diflunisal 1000 mg was compared with that of lornoxicam 16 mg in 40 ASA I patients undergoing surgical removal of bilateral impacted third molars. The impacted third molar teeth on one side were removed at the first surgical appointment using one of the two drug regimens being assessed and the teeth on the contralateral side were removed at a second appointment using the alternate drug regimen; all operations were performed by the same surgeon. Acetaminophen up to 2000 mg daily was provided as rescue medication. The postoperative rescue analgesic consumption was recorded and pain scores were evaluated with a visual analogue scale at 2, 4, 6, 12 and 24h postoperatively. No statistically significant differences were found between groups with respect to rescue analgesic consumption and postoperative pain scores. Pre-emptive administration of both NSAIDs proved to be effective in the management of pain following the surgical removal of impacted third molar teeth.

The effect of anesthetic technique on early postoperative renal function after donor nephrectomy: a preliminary report.

General and regional anesthesia may both be used successfully in donor nephrectomy although the use of regional anesthesia is rare. We compared the remaining kidney function during general (n = 10) versus combined spinal-epidural (n = 10) anesthesia for donor surgery. Blood biochemistry data were collected preoperatively and postoperatively, while renal function was assessed by scintigraphy and urine levels of microalbumin, creatinine, Na, K, Ca and creatinine clearance rate were measured/calculated in 24-hour urine samples collected preoperatively and on postoperative day 2. There were no differences preoperatively and on postoperative day 2 with respect to glomerular filtration rate, microalbuminuria, or creatinine clearance rate (P > .05 for all). There were also no differences between the groups with respect to other scintigraphic findings preoperatively and on postoperative day 2 (P > .05 for all). The results suggest that general or combined spinal-epidural anesthesia for donor nephrectomy have similar effects on the remaining donor kidney function.

Single-stage open reduction through a medial approach and innominate osteotomy in developmental dysplasia of the hip.

We treated 15 hips (15 patients) with developmental dysplasia by a single-stage combination of open reduction through a medial approach and innominate osteotomy. The mean age of the patients at the time of operation was 20 months (13 to 30). The mean follow-up period was 9.6 years (4 to 14). At the final follow-up, 14 hips were assessed clinically as excellent and one hip as good. Radiologically, ten hips were rated as class I, four as class II and one as class III according to the criteria of Severin. No avascular necrosis was seen. No patient required subsequent surgery. Our results indicate that satisfactory results can be obtained with the single-stage combination of open reduction by the medial approach and innominate osteotomy for developmental dysplasia of the hip in a selected group of children older than 12 months. To our knowledge, no similar combined technique has been previously reported.

Regional versus general anesthesia for donor nephrectomy: effects on graft function.

Various general and regional anesthesia methods are used successfully in living-donor kidney transplantation. This study compared kidney graft function after general versus combined spinal-epidural anesthesia for donor nephrectomy. The study groups included recipients who received grafts from donors who had undergone nephrectomy under general anesthesia (GA group; n=10), and recipients who received grafts from donors who had combined spinal-epidural anesthesia (CSE group, n=10). Standard continuous epidural anesthesia was administered during all transplantations. Graft function was assessed using scintigraphy and Doppler ultrasonography on days 3 and 7. Urine levels of microalbumin, creatinine, and creatinine clearance rate were measured/calculated in 24-hour urine samples collected on postoperative days 3 and 7. There were no differences on either day 3 or day 7 with respect to glomerular filtration rate, microalbuminuria, or creatinine clearance rate (P >.05 for all). There were also no differences between the groups with respect to other scintigraphic findings on day 3 or day 7 (P >.05 for all). Ultrasonography on day 7 showed significantly higher mean peak systolic flow in the main renal artery in the CSE group than in the GA group (P=.035). The results suggest that GA and CSE for donor nephrectomy have similar effects on kidney graft function in recipients.

Aneurysmal bone cyst of the sternum: a case report of successful treatment with radiotherapy.

An unusual case of a lytic, expanding lesion of the manubrium with histological diagnosis of aneurysmal bone cyst in a 13-year-old girl is presented. After a recurrence following primary surgery, the patient was treated successfully by external beam radiotherapy. A total dose of 25.2 Gy was delivered using conventional fractionation (1.8 Gy day(-1)) to the whole sternum. She remains recurrence- and symptom-free 46 months after the end of the treatment. This is the sixth patient with primary aneurysmal bone cyst in the sternal region, the first paediatric patient for this location, and the first case of its kind treated exclusively by radiotherapy ever reported in the literature. The histopathological, radiological and clinical findings of the patient are presented, relevant literature is reviewed, and radiotherapeutic management of such lesions is discussed.

Reduced jugular venous oxygen saturation during rewarming from deep hypothermic circulatory arrest: cerebral overextraction?

Deep hypothermic circulatory arrest may impair cerebral cellular functions, and physiological parameters following circulatory arrest may deviate from the normal. The intention of this study was to monitor jugular venous oxygen saturation during cardiopulmonary bypass before and after deep hypothermic circulatory arrest. Jugular venous oxygen saturation were obtained on 18 patients by using a retrograde jugular vein catheter during replacement of the ascending aorta. Indications for operations were ascending aortic dilatation (n=15) and acute aortic dissection (n=3). Hypothermic cardiopulmonary bypass (233+/-60 min), cardioplegic arrest (105+/-37 min) and circulatory arrest (22+/-7 min) were utilized during the operations. Jugular venous oxygen saturation increased during hypothermia and decreased during rewarming. Compared with cooling, jugular venous oxygen saturation during the initial part of rewarming were significantly lower (87+/-5% vs. 97+/-1%, 89+/-4% vs. 95+/-2%, 81+/-4% vs. 87+/-5% at 16, 20 and 24 degrees C respectively, p<0.05). One patient required re-exploration because of bleeding. All patients were found neurologically normal before being discharged from the hospital (mean 14+/-7 days). In conclusion, jugular venous oxygen saturation is inversely related to the body temperature in patients undergoing hypothermic cardiopulmonary bypass. Significantly decreased jugular venous oxygen saturation during the initial part of rewarming may signify an increased cerebral extraction of oxygen.

Three-headed reversed palmaris longus muscle: a case report and review of the literature.

The palmaris longus muscle (PLM) is extremely variable both in number and form. We present the first reported case of three-headed reversed PLM in a 36-year old woman. The relevant literature is reviewed. Variations of the muscles of the forearm and specifically the PLM are not uncommon. However, different rates are given for the types and agenesis of PLM. In one study, the incidence of agenesis was 12.8% and other anomalies were 9%. 15 cases of reversed PLM have been reported in the literature. In our case, the three-headed PLM was resected. The patient's symptoms resolved and at 1-year follow-up she remains symptom-free.

Effects of inactivated influenza virus vaccination on bronchial reactivity symptom scores and peak expiratory flow variability in patients with asthma.

Even though annual influenza vaccinations are recommended by many authorities, some doctors may be reluctant to vaccinate asthmatic patients because of the risk of inducing bronchial reactivity and exacerbating the asthma. In this study we investigated the effect of inactivated trivalent influenza vaccine on airway reactivity symptom scores and peak expiratory flow (PEF) variability in 24 patients with mild stable asthma. Baseline spirometry and methacholine challenge tests were performed on all patients. Patients were then asked to record their peak expiratory flow every morning and evening, complete daily symptom score charts (morning tightness, daytime asthma, cough, and night asthma), and note bronchodilator usage for 1 week. After baseline measurements, the patients were allocated to inactivated vaccine and placebo in a random and single-blind manner. The lung function measurements and methacholine challenge tests were repeated 1 week after vaccination and placebo administration at the same time of day. PD20 (mg/mL) methacholine doses were 3.06+/-3.0 mg/mL before vaccination, 2.96+/-3.2 mg/mL after vaccination, and 2.76+/-2.91 mg/mL after placebo administration. There were no significant changes in PD20 methacholine after influenza vaccination (p>0.05). There were also no significant changes in symptom scores, bronchodilator usage, and PEFR after vaccination (p>0.05). None of the patients experienced significant local or systemic side effects after vaccination. Immunization with inactivated influenza vaccine does not induce clinical exacerbations of asthma or airway hyperreactivity in patients with mild asthma.

Replantation in children.

The rates of survival of the amputated part and the functional outcomes were studied retrospectively after 13 replantations and 12 revascularizations in 25 children. The ages of the patients ranged from 2 to 15 years (mean, 6.4 years). The average duration of follow-up was 4.2 years (range, 2 to 7 years). The survival rate was higher after revascularization (94.6%) than after replantation (84.6%). Sensory recovery of all digits was satisfactory. The mean growth rate of replanted digits relative to contralateral digits was 80%. Functional results were rated as excellent in 11 cases, good in 8 cases, moderate in 2 cases, and poor in 1 case. In order to prevent functional and growth disturbances and due to cosmetic reasons, replantation or revascularization should definitely be tried for children.
