Airbag-Associated Ocular Trauma

Airbags have received widespread recognition as an effective means of enhancing automobile safety. They are particularly effective in frontal and front angle collisions which otherwise would be fatal or cause serious injuries. Inflation of the bag helps protect the driver and front-seat-passenger from hitting the steering wheel, dashboard or windshield. In frontal crashes airbags have reduced driver deaths, hospital admission rates, and incidence of brain injury. On the other hand, an increasing variety of airbag-associated organ injuries has been reported, including blunt ocular and chemical trauma. 2 cases of ocular trauma due to airbags which resulted in choroidal rupture with disastrous outcome in terms of visual acuity are presented. Since the very first report in May 1991 of airbag-associated ocular trauma until June 1996, there has apparently been only 1 case of choroidal rupture due to airbag-associated trauma, presented in 1 sentence of a brief report. Although airbag-related eye trauma may be relatively infrequent, the severity of the injuries incurred, especially when the posterior segment of the eye was involved, warrants research on new airbag design that minimizes the risk of ocular injury. Meanwhile all cases of airbag-associated ocular trauma should be reported, so that medical staff, the general population and car manufacturers will become more aware of this medical issue.

Benign cecal ulcer is a rare lesion, usually diagnosed during operation for suspected acute appendicitis or peritonitis of unknown origin. In the past, right hemicolectomy was recommended as the treatment of choice because of the difficulty in differentiating malignant lesions from benign cecal ulcers. However, in recent reports a more conservative approach has been suggested, consisting of selective colectomy followed by frozen section biopsy. This approach is aimed at preventing unnecessary excision of the colon and conserving the ileocecal valve. We present a 47-year-old woman operated for right lower quadrant peritonitis, believed to be due to acute appendicitis. On exploration, a biopsy-proven benign cecal ulcer was found and resected.

Erythromycin is considered the drug of choice in the treatment of streptococcal pharyngitis in patients allergic to penicillin. However, in recent years several publications, especially in Finland and Italy, showed high resistance rates of S. pyogenes isolates to erythromycin and other new macrolides. To evaluate the situation in Israel, we checked the MIC of isolates from patients with tonsillitis during 1996. E-test results showed an MIC-50 of 0.23, 0.13 and 0.47 mcg/ml for erythromycin, clarithromycin and roxithromycin, respectively and a MIC-90 of 0.37, 0.23 and 0.78 mcg/ml. Only 2 isolates (2.1%) were partially or completely resistant to all 3 antibiotics. We conclude that empiric therapy with macrolides in Israel is still a viable option and can be recommended in S. pyogenes tonsillitis for patients allergic to penicillin.

Occupational Accidents and Eye Injuries

To determine the prevalence of occupation-related eye injuries, we analyzed the records of 24,632 patients treated at our emergency surgical department over a 3-year period. Occupational accidents accounted for 17.6% of such cases. A third of them (1374 patients) were referred to the ophthalmic emergency room for further examination. In 89% (1223) of these, at least 1 pathological ocular finding was detected, and 8.3% (114) of them were hospitalized. Penetrating eye injuries were found in 5.2%(72). The commonest eye injury was corneal foreign body found in 42.8%.

We determined spermatogenic patterns of seminiferous tubules in azoospermic infertile men and evaluated the prevalence of bilateral testicular homogeneity. 185 azoospermic men underwent bilateral testicular fine-needle aspiration (TFNA) in which each testis was punctured at 3 different positions. Aspirated material was stained and classified according to the most mature spermatogenic cell type present or whether only Sertoli cells were present. 35.7% had spermatozoa in their testes, 36.2% had spermatogenic maturation arrest, and 28.1% had only Sertoli cells in their seminiferous tubules. In 15.6% of all patients, the diagnosis in 1 testis differed from that in the other. In only 73.2% of those with testicular spermatozoa was it bilateral. In the remaining 26.9%, only Sertoli cells, spermatocytes or spermatids were found as the most mature cell type in the other testis. The study definitely indicates that fertilization with retrieved testicular spermatozoa should not be offered to azoospermic patients without prior evaluation of the seminiferous tubue spermatogenic pattern in both testes.

Retrospective analysis of a series of 32 motorcyclists admitted after road accidents was performed. 62% were injured on scooters with 50 cc engine capacity and most of the combined injuries occurred in this group. Most crashes occurred at road junctions.Riders of scooters with larger engine capacities tended to wear protective garments as opposed to riders with smaller engines. There was no correlation between engine capacity and severity of injury. We conclude that motorcyclists should receive special education, especially as to behavior on entering road junctions. We recommend that taxes on protective garments should be lowered in order to encourage motorcyclists to use them.

Disappointing Response of Chronic C Hepatitis to Interferon

From February 1990 to August 1995 we treated 58 patients with chronic hepatitis C using alfa-interferon, 3 million units 3 times weekly for 6 months. Of the 48 patients with adequate follow-up, 34 did not respond to treatment at all. 10 patients responded, but within a few months hepatic enzymes again increased. These 2 groups can be considered failures of interferon treatment. In 4 patients enzymes remained normal for the duration of follow-up, (10-34 months). Even in this small group, 1 patient had a positive test for HCV RNA after completion of treatment. A partial explanation of our disappointing results may be the high prevalence of a subtype of C hepatitis-subtype 1b, which has recently been reported in Israel. This strain is particularly resistant to interferon. The means to define subtypes were not, and as far as we know are not yet available in Israel. Various groups have attempted to improve the outcome of treatment of hepatitis C, which in other hands too was still far from satisfactory. Thus, regimens of interferon utilizing higher doses and longer periods of treatment are being evaluated, as well as the addition of Ribavirin, which hopefully will improve results.

Separation of Conjoined Twins: The Anesthesiologist's Perspective

Managing anesthesia care for separation of conjoined twins poses a special challenge for the anesthesia team. Early preparation, thorough understanding of the anatomical and the physiological consequences of this complex anomaly, as well as careful coordination with the teams of surgeons, nurses and operating room personnel are mandatory to assure successful separation of the conjoined twins. It is recommended that the mother be transferred to and the babies be delivered at a tertiary care medical center, like the Children's Hospital. Special attention is devoted during the surgical procedure to cardiovascular stability, drug disposition, fluid balance and temperature control. The multidisciplinary team approach makes this complex surgery a success. When postoperative survival cannot be guaranteed for both twins, close contact and consultation is mandated with the parents, medical personnel and religious and legal advisors.

The medical records of 24,632 patients treated in our surgical emergency service over a 3-year period were reviewed to determine the frequency and characteristics of ocular trauma caused by motor vehicle accidents (MVA). MVA-related injuries accounted for 13.9% of all visits to the service and involved 1106 of the patients (33%), of whom 77% were young males. At least 1 pathological finding was found in 858 (77.6%) and 169 (15.2%) were admitted. 16 patients sustained very severe ocular injuries which resulted in poor vision.
