Use of a tourniquet in the internal fixation of fractures of the distal part of the fibula. A prospective, randomized trial.

A prospective, randomized trial was undertaken to determine the rate of complications after the use of a tourniquet during open reduction and internal fixation of simple, closed fractures of the distal part of the fibula. Forty patients were operated on with use of a tourniquet (Group 1) and forty patients, without use of a tourniquet (Group 2). The average duration of the operation was significantly different between the two groups (41 +/- 9 minutes for Group 1 compared with 53 +/- 12 minutes for Group 2 [p = 0.026]). There were more complications in the patients in Group 1, two of whom had an isolated deep-vein thrombosis of the calf. The wound was possibly infected in eleven patients (seven in Group 1 and four in Group 2 [p < 0.05]) and frankly infected in three patients, all in Group 1 (p < 0.05). The plaster-of-Paris cast needed to be changed in three patients from Group 1. The patients in Group 1 returned to work an average of one week later than those in Group 2. The mean duration of follow-up was eighteen months (range, nine to thirty-two months). Given the lower prevalence of postoperative complications and the shorter time to recovery for the patients in Group 2, we believe that it is justified not to use a tourniquet in the operative treatment of simple, isolated fibular fractures.

Post-viral fatigue syndrome. A longitudinal assessment in varsity athletes.

Maximal oxygen uptake, anaerobic threshold (AT), isometric strength of the elbow flexor and knee extensor muscles, isometric strength endurance exhaustion time (prolonged contraction at 66% of maximal isometric strength), uphill sprinting exhaustion time were longitudinally studied in eight varsity endurance runners with post-viral fatigue syndrome (PVFS). Prolonged impairment of exercise performance is evident during the course of PVFS. Although maximal oxygen uptake (VO2max) had returned to pre-infection values 13 months after the viral illness (4.160 vs 4.0 L.min-1), AT was still significantly reduced [52 ml.kg-1.min-1, 18.6 km.hr-1, 176 bpm, and 82% of VO2max vs. 49.1 ml.kg-1.min-1 (p < 0.05), 175 bpm (NS), 17.2 km.hr-1 (p < 0.01) and 79% of VO2max (NS)]. Maximal isometric contraction strength of the upper limb remained constant (282 N vs. 274 N), while knee extensor muscles strength decreased significantly (730 N vs. 701 N, p < 0.05). Strength endurance was still significantly reduced by the end of the study (arm average pre-infection: 46.2 sec; end of study: 29.3 sec, p < 0.001; leg average pre-infection: 66.4 sec; end of study: 49.1 sec, p < 0.01). Up hill sprinting time was similarly reduced by the end of the study period (29.3 sec vs. 16.2 sec, p < 0.01). Both aerobic and anaerobic exercise variables are seriously affected by post-viral fatigue syndrome, and one year may not be sufficient to fully recover.

Mediopatellar synovial plica of the knee in athletes: results of arthroscopic treatment.

The long-term results (9-87 months) of the arthroscopic treatment of unilateral mediopatellar synovial plica of the knee in 102 athletes are reported. In all patients a large and/or fibrotic inflamed mediopatellar plica impinging on the femoral condyle on knee flexion was identified and trimmed. Chondromalacia patellae was detected in 38 patients. The impingement lesion was seen in 13 knees. In one patient, a minor tear of the lateral meniscus was trimmed, and one patient was found to suffer from a clinically asymptomatic partial tear of the anterior cruciate ligament. Isometric strength testing of the quadriceps revealed marked decrease at the second postoperative week, with subsequent gradual recovery. The results obtained justify arthroscopic treatment in a young, extremely active population.

Chronic peritoneal dialysis catheters in pediatric patients: experience of the Italian Registry of Pediatric Chronic Peritoneal Dialysis.

During the period 1986-1991, 140 pediatric patients [age < or = 15 years at the start of chronic peritoneal dialysis (CPD)], belonging to 15 dialysis centers, were enrolled in the Italian Registry of Pediatric Chronic Peritoneal Dialysis. Data on 188 peritoneal catheters were collected: 161 catheters were Tenckhoff (144 double-cuff, 17 single-cuff), and 27 were two-cuff Valli-type catheters. All catheters were surgically inserted; the entry site was in the midline in 84 cases and paramedian in 104. An omentectomy was performed in 78.8% of the cases. Apart from peritonitis, there were 161 catheter-related complications (103 exit-site infections, 17 leakages, 15 obstructions, 15 outer-cuff extrusions, 5 hemoperitoneum, 6 others) observed during 2687.5 dialysis-months, with an incidence of one complication every 16.7 dialysis-months. Fifty-five catheters (29.2%) were removed; infection (39 cases) was the main cause for removal, followed by obstruction (9 cases), dislocation, and outer-cuff extrusion (2 cases each). Actuarial survival of all catheters was 79.7% at 1 year, 66.6% at 2 years, 42.8% at 3 years, and 39.8% at 4 years. No difference in catheter survival was observed according to the entry site. When considering the age of the patients at catheter insertion, a difference close to statistical significance was found (p = 0.06).

Dynamic varus heel cup: a new orthosis for treating pes planovalgus.

Pes planovalgus is an extremely common deformity and still not completely understood. Its pathogenesis and the possibilities for treating it with shoe inserts are still under debate. While the controversy between abstentionists and interventionists remains a fact, since a certain number of flat feet persist into adult age and cause disability, a new type of orthosis is proposed. This has been tested on children affected with grade III pes planovalgus and with all the worst clinical, objective and prognostic parameters. The study was carried out with a control group using traditional Lelièvre insoles. The results were extremely good and correction was achieved in a significantly higher number of patients than in the control group.

Population based data on urinary excretion of calcium, magnesium, oxalate, phosphate and uric acid in children from Cimitile (southern Italy).

Population based data on 24-h urinary excretion of calcium, oxalate, magnesium, phosphate, uric acid and creatinine were collected from 220 children (aged 3-16 years) living in Cimitile, Campania, southern Italy. Mean excretion rates for 7 days were correlated with age, body weight, body mass index and height. The prevalence of hypercalciuria (greater than 4 mg/kg body weight) and of hyperoxaluria (greater than 60 mg/day) were 9.1% and 1.8%, respectively. The same 20 children were also identified as hypercalciuric when a calcium/creatinine ratio of greater than 0.15 was considered. No significant differences between boys and girls were found in the urinary excretion of the five constituents implicated in urolithiasis. The study data provide additional childhood reference values for urinary excretion of compounds related to stone formation.

Glucagon-independent renal hyperaemia and hyperfiltration after an oral protein load in Child A liver cirrhosis.

The work was designed to study the effects of a meat meal on glomerular filtration rate (GFR), renal plasma flow (RPF), and plasma concentrations of glucagon, insulin, growth hormone, renin, aldosterone, total amino acids, and NH3 in healthy humans (H) as well as in patients with Child A liver cirrhosis (LC). The meat meal produced renal hyperaemia and hyperfiltration without changes in the filtration fraction. Fractional Na excretion in urine increased significantly after the meat meal only in LC. Hyperinsulinaemia and hyperglucagonaemia were seen at baseline in LC and were not affected by the meat meal, whereas in H glucagon concentration increased significantly over baseline within 30 min from the meat meal and insulin within 60 min. Growth hormone concentration was normal at baseline in LC and increased significantly 120-180 min after the meal, whereas it was not affected in H. Renin and aldosterone were stable in both H and LC. Plasma amino acid concentration began to increase 60 min after the meat meal, when hyperfiltration was present. The data indicate that in human Child A cirrhosis of the liver renal haemodynamic response to a meat meal is independent of changes in glucagon.

Histochemistry of the triceps surae muscle in idiopathic congenital clubfoot.

The histochemical composition of the triceps surae muscle was investigated in 13 previously unoperated children (age 9-24 months) with unilateral idiopathic clubfoot. On both the normal and the affected side, the percentage of type I fibers was significantly higher than that of the other fiber types. The muscle biopsies from the clubfoot side showed an increase in their connective tissue content. The affected side showed a nonsignificant higher percentage of type I fibers, whereas the average capillary density and capillary to fiber ratio were significantly lower.

Five years' experience of the Italian Registry of Pediatric Chronic Peritoneal Dialysis.

The results of the first 5 years' experience of the Italian Registry of Pediatric Chronic Peritoneal Dialysis (CPD) (1986-1990) are presented. Patients of less than 15 years of age at start of dialysis were enrolled and clinical data collected until the age of 19. The number of the dialysis centres participating in the Registry increased from 7 in 1986 to 15 in 1990. The total number of patients on CPD was 119, the number of new patients per year ranged from 15 to 28 and the percentage of all dialysed children treated with CPD increased from 40% in 1986 to 49% in 1990. The age of patients at start of CPD was 8.5 +/- 4.9 years and 16% of them were under 2 years. Only CAPD was utilized in 1986, while CCPD/NPD accounted for 53% and 65% of the treated patients in 1989 and 1990, respectively. At 4 years, patient survival was 91.3% and technique survival 79.3%. A comparison between data of 48 patients on CPD and 34 on hemodialysis, who started dialysis in the period 1989-1990, showed that CPD was the most frequent form of initial therapy (56%) and was the treatment of choice for children younger than 4 years.

Dorsolumbar spine duplication.

We report a case of dorsolumbar spine duplication in a female patient. She had several vertebral anomalies, such as fused vertebrae, hemivertebrae and butterfly vertebrae, together with duplication of the spinal column in the lower thoracic and the whole lumbar tract. Clinically, she had no control of the sphincters, but her gait was only slightly affected. This is probably the third reported case of this rare anomaly.
