Background: Statin-induced myalgia is defined as muscle pain without elevation of serum creatine phosphokinase levels and is a well-known complaint among statin users. Chronic pain syndromes affect a high percentage of the population. These pain syndromes may confound the reports of statin-induced myalgia.

Objectives: To compare the occurrence of chronic pain among patients on statin therapy who developed myalgia with those who did not.

Methods: This study included 112 statin-treated patients, who were followed at the lipid center at Sheba Medical Center. Fifty-six patients had a diagnosis of statin-associated muscle symptoms (SAMS) and 56 did not. Verified questionnaires were used to assess the diagnoses of fibromyalgia, pain intensity, functional impairment, anxiety, and depression in the study population.

Results: Patients with statin myalgia were more likely to fulfil the diagnostic criteria for fibromyalgia than patients without statin myalgia (11 [19.6%] vs. 0, respectively). Patients in the SAMS group exhibited higher levels of anxiety and depression compared with the control group. Female sex, higher scores on the Brief Pain Inventory pain intensity scale, and a Hamilton rating scale level indicative of an anxiety disorder were found to be significant predictors for fibromyalgia in patients presenting with statin myalgia.

Conclusions: A significant percentage of patients diagnosed with statin myalgia fulfilled the diagnostic criteria for fibromyalgia depression or anxiety disorder. Detection of these patients and treatment of their primary pain disorders or psychiatric illnesses has the potential to prevent unnecessary cessation of effective statin therapy.

Background: Previous studies led to the recommendation to schedule planned elective cesarean deliveries at or after 39 weeks of gestation, and not before 38 weeks. The question is whether this practice is appropriate in face of possible risks to the newborn should the pregnancy have to be ended by cesarean section before the scheduled date.

Objectives: To compare the outcomes of newborn infants who were delivered on their scheduled day by elective cesarean section versus those who required delivery earlier.

Methods: This single-center retrospective study was based on medical records covering a period of 18 months. We compared the neonatal outcomes of 272 infants delivered by elective cesarean section as scheduled (at 38.8 ± 0.8 weeks gestation) and 44 infants who had to be delivered earlier than planned (at 37.9 ± 1.1 weeks). 

Results: We found no morbidity directly related to delivery by cesarean section before the scheduled date. There were no significant differences in the need for resuscitation after delivery. Although more of the infants who were delivered early were admitted to intensive care and overall stayed longer in the hospital (5.8 ± 7.3 vs. 3.9 ± 0.8 days, P < 0.02), their more severe respiratory illness and subsequent longer hospitalization was the result of their younger gestational age. Transient tachypnea of the newborn was associated with younger gestational age at delivery in both groups.

Conclusions: We suggest continuing with the current recommendation to postpone elective cesarean singleton deliveries beyond 38–39 weeks of gestation whenever possible.

Objectives: To evaluate factors that might influence the decision of pregnant women to choose chorionic villous sampling for prenatal testing.

Methods: The study group comprised 239 women referred for prenatal diagnosis who elected to undergo CVS[1]. The data were analyzed according to indication, ethnic group and religion.

Results: Among women undergoing CVS because of advanced maternal age and because of anxiety, we noted a significantly high proportion of unbalanced families, i.e., with three or more children of the same gender and deviated gender ratio. We found a significant excess of males among the Jewish families and a significant excess of females among the non-Jewish families. Jews were over-represented in the monogenic group while Christian Arabs were over-represented in the maternal age/anxiety group.

Conclusions: The proportion of women who chose CVS for prenatal diagnosis varied according to indication, ethnic group and religion. The data in this study indicate that CVS may have been utilized for balancing families with ≥ 3 or more children of the same sex. Christian Arabs chose CVS more often than the other groups. Jewish women may have utilized CVS for family balancing of both sexes, while non-Jews may have utilized CVS for balancing families with ≥ 3 daughters.
