We examined all ceftriaxone-resistant Escherichia coli isolates obtained from clinical samples during 16 months (1 Dec. '97 - 31 Mar. '99). A total of 97 resistant isolates from 36 patients were obtained, mostly from urine specimens. Of these patients, 35/36 were over 75 years old, most lived in nursing homes, were dependent on nursing in their daily lives, and were incontinent and/or had indwelling catheters.

All 97 isolates had similar susceptibility profiles: resistant to ciprofloxacin, gentamicin, ampicillin, amoxycillin/clavulanate, tricarcillin/clavulanate, aztreonam, and cefuroxime; decreased susceptibility to ceftazidime and cefepime; and susceptible to imipenem and meropenem. Double-disc tests indicated that all strains produced extended spectrum beta-lactamase(s). All the isolates belonged to 1 of 3 E. coli serotypes: 79 were 0153:H31, 13 were 0142:H10, and 5 were 0102:H6.

Pre-induction sports participation of 392 elite infantry recruits was evaluated for correlation with incidence of stress fractures (SF) during 14 weeks of basic training. 23.7% developed lower extremity stress fractures. 72% of the recruits had participated in sports on a regular basis during the 2 years prior to induction. Their fitness as examined by the Bar-Or induction fitness test, was significantly better than that of those who had not trained. 14.9% of the soldiers who had previously participated in ball games (primarily basketball) as an only sport suffered stress fractures, compared to 31.0% of those whose only sport was running (p<0.005).

Training for only 6 months prior to induction had no effect on the incidence of SF. The reason for the difference between ball games and running is probably related to the higher strains and strain rates developed during ball games and to their multidirectional nature, as compared to running.

These findings suggest that participation in a pre-induction program that includes activities that create strains, such as basketball, can reduce incidence of SF in infantry recruits. The training period has to last at least 2 years.

The records of 537 patients with 750 maxillofaciafractures were reviewed and analyzed. 55 (10.2%) had sport-related injuries and the rest were due to othercauses. The sport-related group was predominantly male (ratio 9:1) with a mean age of 24.5 years. The mandible was most commonly injured (52.5%), followed by the zygomatic complex (32.8%). The incidence of complicated mid-facial fractures was only 2.8%, and of comminuted fractures 9%. This distribution of injuries is most likely due to the relatively low-energy of trauma associated with many sport activities. The relatively low mean age of the patients, most of whom had full dentition, allowed for conservative treatment of most of the mandibular fractures, using closed reduction.

Injuries were caused by 11 different sports. The highest incidence was soccer (45%), followed by skating (15%), basketball (9%) and horse-riding (9%). Contact sports were the cause of injuries in 72.2%, with the highest incidence of trauma due to impact with another player (60%). Better protection of the oral and maxillofacial region is needed, especially during high-contact sport.

Rupture of Pectoralis Major Muscle: Operative Treatment of an Uncommon Sport Injury

Rupture of the pectoralis major muscle in an athlete is rare, but is said to be common in weight lifters. The muscle usually ruptures at the musculotendinous junction during forceful contraction of the muscle in adduction, forward flexion and internal rotation of the arm. We describe an athlete who suffered such a major tear during a rugby game. It was treated surgically and after adequate rehabilitation, athletic activities were resumed.

Primary Subclavian Vein Thrombosis after Intensive Physical Exertion

Subclavian vein thrombosis accounts for approximately 1-2% of recorded deep venous thromboses. It may be primary or secondary, and insertion of a central venous catheter is the most common cause of secondary subclavian vein thrombosis. Traumas, anatomic abnormalities and carcinoma are important additional risk factors for secondary thrombosis. Primary thrombosis of the subclavian veins is known as Paget-Schroetter syndrome. New criteria for its diagnosis include a history of increased upper extremity use prior to onset of symptoms, the presence of a venographically demonstrated thrombus and absence of any definable causes. We describe a 42-year-old woman with a history of intensive physical exertion admitted with swelling, pain and difficulty moving her arm. The diagnosis of primary subclavian vein thrombosis was established from the history of physical effort, results of Doppler ultrasound, and exclusion of other causes of subclavian vein thrombosis. This case suggests that primary subclavian vein thrombosis should be considered in young patients with subclavian vein thrombosis after exclusion of secondary disease.

Suprascapular Nerve Entrapment in a Basketball Player

Rehabilitation Unit and Dept. of Neurology, Western Galilee Hospital, Nahariya

A basketball player was shown to have a suprascapular nerve lesion without any history of shoulder girdle trauma. This acute neuropathy, never previously described in basketball players, is a result of repeated micro-trauma, due to nerve traction over the coracoid notch during violent movement ("dunking" most probably). Clinically, he was unable to abduct his arm and had some difficulty in external rotation. He developed atrophy in both the supra- and the infraspinatus muscles. Nerve conduction latency to the supraspinatus muscle was 8.0 ms, and to the infraspinatus, 8.5 ms. The compound muscle action potential registered in the supraspinatus was 1.224 mV, and in the infraspinatus, 1.237 mV. After 3 weeks of inactivity, recovery was spontaneous and practically complete.
