Background: Breast implant illness (BII) is a rising concern among many patients. Although not fully understood, a connection between silicone breast implants and systemic diseases may be present. This connection may influence the types of breast surgeries performed.

Objectives: To evaluate changing trends in breast surgeries in Israel over time, with regard to implantation, explantation, and implant exchange surgeries.

Methods: In this ecological study, we presented data from four private medical centers in Israel regarding the number of breast implant surgeries performed in the years 2018–2019. Data were collected bi-yearly. The types of surgeries included breast implantation, explantation, and breast implant exchange.

Results: When we summed and compared the yearly data, we saw that the number of implantations in 2018 was 2267 (80.1% of breast implant procedures that year), and 1929 (68.9%) in 2019. The number of implant exchanges in 2018 and 2019 was 482 (17.0%) and 608 (21.7%), respectively. In 2018, 80 (2.8%) explantations were performed and 262 (9.4%) in 2019.

Conclusions: There appears to be a trend in the rise of implant removal surgeries in addition to a decrease in breast implantations. One possible reason may be patient concerns of BII. Another reason may be the increased public interest and discussion about systemic effects of breast implants. More research is needed in this field to achieve better understanding of the phenomenon, the reasons behind it, and the possible solutions and ways of treatment

Background: Hodgkin’s lymphoma is a distinct primary solid tumor of the immune system that shows wide variation in incidence among different geographic regions and among various races. It was previously suggested that susceptible people living in certain parts of Israel had a higher risk of HL[1] because of exposure to unidentified environmental factors in these regions. Compared with other parts of Israel, these regions were characterized by a higher proportion of Israeli-born Jews.

Objectives: To study time trends in the incidence rate of HL in Israeli-born Jews of all age groups during the years 1960–2005.

Results: A total of 4812 Jewish cases of HL were reported to the Israel Cancer Registry during the study period 1960–2005. There has been a persistent increase in the age-standardized incidence rate of HL, all subtypes pooled, in Israeli-born Jews in both men and women. The age distribution pattern in both genders was bimodal in all periods. The highest incidence was observed in the 20–24 year age group: for women (9.13 per 100,000 per year) during the period 1988–1996, and for men (6.60 per 100,000 per year) during the period 1997–2005.

Conclusions: The reported incidence level of HL in Israeli-born young adult Jews in Israel has increased in recent years to high levels compared with other western countries. Our findings suggest a cohort effect to unidentified factors affecting Israeli-born young adult Jews in Israel.

Background: A paradoxical secular trend of an increase in preterm births and a decrease in low birth weights has been reported in many developed countries over the last 25 years.

Objective: To determine if this trend is true for Israeli neonates, and to add new information on secular trends in crown-heel length and head circumference.

Methods: A hospital-based historic cohort design was used. Anthropometric data for 32,062 infants born at Rabin Medical Center in 1986–1987, 1994–1996, and 2003–2004 were collected from the hospital’s computerized registry and compared over time for absolute values and proportional trends.

Results: For the whole sample (gestational age 24–44 weeks) there was a significant increase in mean birth weight (by 41 g), crown-heel length (by 1.3 cm), and head circumference (by 0.1 cm) from 1986 to 2004 (P < 0.001). A similar trend was found on separate analysis of the post-term babies. Term infants showed an increase in mean length and head circumference (P < 0.001), but not weight, and moderately preterm infants (33–36 weeks) showed an increase in mean weight (81 g, P < 0.001) and mean length (1.0 cm, P < 0.001), but not head circumference. The proportion of post-term (42–44 weeks), preterm (24–36 weeks), very preterm (29–32 weeks), extremely preterm (24–28 weeks), low birth weight (< 2500 g) and very low birth weight (< 1500 g) infants decreased steadily and significantly over time (P < 0.002).

Conclusions: Babies born in our facility, term and preterm, are getting bigger and taller. This increase is apparently associated with a drop (not a rise) in the proportion of preterm infants. These results might reflect improvements in antenatal care and maternal determinants.
 

Mortality rates have been falling at all ages, even for very old cohorts, in most western countries as well as in Israel. The question remains open as to whether morbidity rates are also decreasing, especially for Israel’s elderly. While health is improving in almost all industrialized countries, the situation in Israel is not yet resolved. While the more recent cohorts of the young-old (65–74 years) are healthier than their predecessors, Israel’s old-old (75+) may still be lagging behind other countries with regard to improvements in health status. This phenomenon is not well understood but could be explained in part by the more severe formative experiences of many of Israel’s very elderly cohort.

Objectives: To analyze the incidence of mesothelioma in Israel during the years 1960-96, and to project its trend for the following years.

Methods: We conducted a population-based study of the incidence of mesothelioma reported to the Israel Cancer Registry during 1960-96. Time trends were analyzed from data on the annual import of asbestos to Israel, which may indicate the magnitude of past exposure. Based on these findings, trends in the incidence of mesothelioma in Israel were projected for the subsequent years.

Results: A total of 327 cases of mesothelioma were reported to the Israel Cancer Registry during the study period. The incidence in Jews was higher than in Arabs (age-standardized incidence rate 2.64 vs. 1.35 per million/year, respectively). Among the Jewish population, Israeli-born males and males born in Europe and America showed the highest incidence (ASR 4.23 and 4.15 per million/year, respectively). Israeli-born males were 20 years younger than Jewish males born elsewhere. The incidence was twice as high among males than females and increased sevenfold from its nadir (1.17 per million/year) in 1978--80 to its peak (8.5 per million/year) in 1993-96. During a similar period the incidence among females increased from 0.33 to 2.56 per million/year. The incidence in both sexes does not appear to level off. The large wave of immigration from the former Soviet Union that began in 1989 only partly accounts for the increased incidence in 1993-96. The time trend in the incidence of mesothelioma in both sexes parallels the use of asbestos in Israel, which peaked in the years 1976-78.

Conclusions: The incidence of mesothelioma in Israel has increased sharply in recent years, unrelated to a wave of immigration from East Europe, and is predicted to continue to rise for another 10-15 years.
