Background: Pterygium is a common disease in Israel. Different surgical techniques are used to manage it with varying degrees of success.

Objectives: To evaluate the efficacy and safety of a conjunctival autograft after excision of pterygium.

Methods: Excision followed by conjunctival autograft was used to treat 40 eyes of 40 patients with pterygium. The surgical results were evaluated retrospectively. Follow-up continued for a median of 296 days (range 6±1,056); 26 cases were followed for more than 100 days (average 418 days) and comprised the study cohort. All reported procedures were performed consequentially and by one surgeon in the Tel Aviv Sourasky Medical Center, Israel between 1 June 1997 and 31 March 2000.

Results: There were two recurrences of pterygium (2/26, 7.7%) 2 months postoperatively. There were no major complications. Super-ficial corneal vessels (without concurrent fibrosis) appeared in 10 of 17 cases sutured with nylon, but none occurred in any of the seven grafts sutured with vicryl (P = 0.068). The average LogMAR-corrected visual acuity of the study group improved slightly, from 6/16.5 to 6/11 (P = 0.003).

Conclusions: Excision of pterygium with a conjunctival autograft is a safe and effective operation, with no procedure-specific added surgical risks. The relatively long surgical time and microsurgical methods required to perform the procedure properly have hindered its acceptance as the mainstream approach to pterygium management. Long-term follow-up is needed for better discernment of the surgical results in Israel.
 

Background: The threat to the individual’s physical integrity and well-being as well as to those of significant others, the disruption of normal patterns of life, and property losses make wartime a highly stressful condition.

Objectives: To assess the level of psychological distress in primary care attenders in a district of Jerusalem (Gilo) that experienced long-term exposure to gunfire.

Methods: A self-administered questionnaire exploring emotional distress (anxiety and depression symptoms), fire exposure, patterns of help-seeking behavior, and prescription of sedative or hypnotic drugs was administered to a sample of 125 consecutive attenders to a general practitioner during a 10 week period in the autumn of 2001. Eighty-four attenders residing in Gilo were compared with 41 attenders residing in neighborhoods that had not been under fire. T-tests and Mann-Whitney two-sample tests were used to determine statistical significance of differences.

Results: The mean distress score was significantly higher among the Gilo residents than among their counterparts in other neighborhoods (1.1 ± 0.8 vs. 0.8 ± 0.5, t = 1.73, P <0.01); 15.5% of the former reported probable clinically significant distress. Emotional distress was associated with periods of intensive gunfire exposure, psychological care-seeking behavior, and the prescription of sedative or hypnotic drugs. No significant differences in distress levels were found between those living in zones of Gilo that were at differential gunfire risk, nor between those whose houses and cars were or were not damaged.

Conclusions: War-related life events would seem to be associated with elevated emotional distress. A motivated primary care physician could easily and reliably ascertain the attenders’ psychological status and identify those requiring psychological support. These identification and intervention stages are facilitated if the specialized services are community-based.

Background: As air travel increases and the number of commercial and non-commercial flights rises so does the number of aircraft accidents. The improved safety standards of the aviation industry result in a growing number of survivors of aircraft crashes, but there are no management guidelines for the treatment of aircraft crash survivors.

Objectives: To present our experience in treating five survivors of a light aircraft crash that occurred in August 1995 near Jerusalem.

Results: All five survivors sustained vertebral column injuries, which was the only injury in most of the survivors. We discuss the mechanism of injury.

Conclusions: Investigation of injuries’ pattern in survivors of aircraft crash is important for establishing management protocols in trauma centers.
 

Background: Each winter influenza activity is a major cause of morbidity and mortality both in Israel and worldwide.

Objectives: To identify the influenza viruses active in Israel during the winter season and to assess the extent of influenza morbidity.

Methods: Information was collected on a population of 18,684 individuals enrolled in two community clinics in central Israel. It included the total number of visits for acute respiratory infection – including influenza and influenza-like illness (ARI/flu-like) – during a 20 week surveillance period (23 November 1997 to 27 March 1998) and the percent of influenza virus isolates in nasopharyngeal specimens from a sample of patients with ARI/flu-like collected on a weekly basis during the same period.

Results: A total of 5,947 visits for ARI/flu-like were recorded among 18,684 enrolled patients in two community clinics (18.1%). The progressive increase in the number of visits for ARI/flu-like reached a peak on week 2/98 with 597 visits and a rate of 31.95 visits per 1,000 population. After this, a decrease to the initial values was evident by week 12/98. Most affected patients were in the age groups 5–14 and 65 years and over, with a rate of 733.5 and 605.3 visits per 1,000 population, respectively. Influenza virus was isolated from 92 of the 426 nasopharyngeal specimens (21.6%). The most commonly detected strain was A/Sydney/5/97(H₃N₂) like (77.2%). The peak rate of isolates was recorded at the beginning of January (01/98).

Conclusions: A/Sydney/5/97(H₃N₂) like-strain was the dominant influenza virus. Its presence did not prevent the simultaneous activity of influenza A/H₁N₁ virus. The dynamic of the clinical disease as expressed by the weekly visit rate for ARI/flu-like was similar to the temporal pattern of the virological findings. The extent of morbidity suggests moderate epidemic activity.
 

Background: Previous studies have documented an increased incidence of cardiac mortality and sudden death during winter months.

Objectives: To evaluate seasonal variation in sudden death in a hot climate such as the desert region of southern Israel.

Methods: We analyzed the files of 243 consecutive patients treated for out-of-hospital sudden death by the Beer Sheva Mobile Intensive Care Unit during 1989-90. Daily, monthly and seasonal incidence of sudden death was correlated with meteorological data, including temperature, heat stress, relative humidity and barometric pressure.

Results: The seasonal distribution of sudden death was 23% in spring, 21% in summer, 25% in autumn and 31% in winter (not significant). In patients with known heart disease there were more episodes of sudden death in cold weather (<15.4°C) than hot (>34.2°C) (16 vs. 3, P<0.05). Resuscitation was less successful in cold compared with hot weather (28 vs. 11, P<0.05). Of patients older than 65 years, 11 sustained sudden death when heat stress was below 12.4°C compared to 2 patients when heat stress was above 27.5°C (P=0.05).

Conclusion: Despite the warm desert climate, there were more cases of sudden death in older patients and in those with known heart disease during the winter season and on particularly cold days.
