[Clinical Picture] Woe sushi: gastric anisakiasis

The Lancet - Sa, 13/10/2018 - 00:00
A 40-year-old man presented to our emergency department with acute upper abdominal pain 8 h after ingestion of sushi. During physical examination, he was found to have tenderness in the epigastric region. Abdominal CT showed diffuse thickening of the wall of the gastric body with surrounding fat stranding. Emergency gastroscopy identified a 15 mm long larva of the nematode Anisakis simplex penetrating the inflamed body of the stomach (figure). Disinfestation rapidly resolved the patient's symptoms.

[Series] Global epidemiology of use of and disparities in caesarean sections

The Lancet - Sa, 13/10/2018 - 00:00
In this Series paper, we describe the frequency of, trends in, determinants of, and inequalities in caesarean section (CS) use, globally, regionally, and in selected countries. On the basis of data from 169 countries that include 98·4% of the world's births, we estimate that 29·7 million (21·1%, 95% uncertainty interval 19·9–22·4) births occurred through CS in 2015, which was almost double the number of births by this method in 2000 (16·0 million [12·1%, 10·9–13·3] births). CS use in 2015 was up to ten times more frequent in the Latin America and Caribbean region, where it was used in 44·3% (41·3–47·4) of births, than in the west and central Africa region, where it was used in 4·1% (3·6–4·6) of births.

[Series] Short-term and long-term effects of caesarean section on the health of women and children

The Lancet - Sa, 13/10/2018 - 00:00
A caesarean section (CS) can be a life-saving intervention when medically indicated, but this procedure can also lead to short-term and long-term health effects for women and children. Given the increasing use of CS, particularly without medical indication, an increased understanding of its health effects on women and children has become crucial, which we discuss in this Series paper. The prevalence of maternal mortality and maternal morbidity is higher after CS than after vaginal birth. CS is associated with an increased risk of uterine rupture, abnormal placentation, ectopic pregnancy, stillbirth, and preterm birth, and these risks increase in a dose–response manner.

[Series] Interventions to reduce unnecessary caesarean sections in healthy women and babies

The Lancet - Sa, 13/10/2018 - 00:00
Optimising the use of caesarean section (CS) is of global concern. Underuse leads to maternal and perinatal mortality and morbidity. Conversely, overuse of CS has not shown benefits and can create harm. Worldwide, the frequency of CS continues to increase, and interventions to reduce unnecessary CSs have shown little success. Identifying the underlying factors for the continuing increase in CS use could improve the efficacy of interventions. In this Series paper, we describe the factors for CS use that are associated with women, families, health professionals, and health-care organisations and systems, and we examine behavioural, psychosocial, health system, and financial factors.
