A reflection of Africa's cardiac surgery capacity to manage congenital heart defects: a perspective

Congenital heart defects (CHDs) are birth abnormalities that may drastically alter the structure and functionality of the heart. For 70% of infants with congenital disorders to survive or maintain a better quality of life, surgery is necessary. Over 500 000 of the 1.5 million CHD cases reported annually, or 1% of all live births, occur in Africa, according to the WHO. A surmounted 90% of these patients are from Africa, and as a consequence, 300 000 infants die annually as a result of poor care or difficulty accessing adequate healthcare. However, the high prevalence of CHDs, precipitated by a plethora of aetiologies worldwide, is particularly pronounced in Africa due to maternal infectious diseases like syphilis and rubella amongst the pregnant populace. In low- and middle-income countries, especially in Africa, where foreign missions and organizations care for the majority of complicated cardiac surgical patients, access to secure and affordable cardiac surgical therapy is a substantial issue. Interventions for CHDs are very expensive in Africa as many of the continent's domiciles possess low expenditures and funding, thereby cannot afford the costs indicated by associated surgical treatments. Access to management and healthcare for CHDs is further hampered by a lack of trained surgical personnel, specialized tools, infrastructure, and diagnostic facilities in Africa.

A serial section study of visually normal posterior pelvic peritoneum from baboons (Papio cynocephalus, Papio anubis) with and without spontaneous minimal endometriosis

OBJECTIVES

To determine if microscopic endometriosis exists in visually normal pelvic peritoneum from baboons with and without endometriosis.

DESIGN

Observational histologic study at Institute of Primate Research, Nairobi, Kenya.

SUBJECTS

Seventeen baboons including 13 adult females (5 with histologically proven endometriosis, 8 with a normal pelvis) and 4 juveniles (1 female and 3 males).

INTERVENTIONS

Diagnostic laparoscopy with identification of visually normal pelvic peritoneum before euthanasia, followed by laparotomy with excision of a large area (at least 4 x 6 cm or 24 cm2 per animal, 408 cm2 surface in all baboons) of this visually normal-appearing peritoneum.

MAIN OUTCOME MEASURE

Presence of microscopic endometriosis (endometrial glands and stroma) in serial sections of visually normal pelvic peritoneum.

RESULTS

Two adjacent glandular structures compatible with endometriosis were found in normal peritoneum obtained during menses from one female baboon without macroscopic disease. Microscopic endometriosis was not detected in the other female primates with or without macroscopic disease or in male animals.

CONCLUSION

Microscopic endometriosis was found in only 1 of 14 female baboons (prevalence 7%; 95% confidence interval 0% to 33%) with visually normal pelvic peritoneum. These findings suggest that, with the paucity of human data available, more studies are needed before concluding that massive microscopic disease exists in visually normal-appearing peritoneum of women.
