Assessment of Iodine Deficiency and Goitre Incidence in Parts of Yewa Area of Ogun State, Southwestern Nigeria

This study was carried out to determine the occurrence, prevalence and contributing factors to the incidence of goitre in Yewa north local government area of Ogun state, southwestern Nigeria. To achieve these objectives, soil, water, and cassava tubers were collected from four villages – Igbogila, Egua, Sawonjo and Imoto and from Lagos (about 250 m to the ocean) as a reference location, in order to determine their iodine concentrations. The results of the analyses indicated a soil mean iodine range of 2.1–5.8 μg g⁻¹; a cassava mean iodine value of 2.3–3.5 μg g⁻¹ and a drinking water mean iodine value of generally <1.0 μg L⁻¹ in all the four villages. These values of iodine in soil and water of the four villages are considered low when compared with the soil iodine value of 7.4 μg g⁻¹ and water iodine value of 6.1 μg L⁻¹ obtained from Lagos. The limestone unit of the study area remains an inhibiting factor in the bioavailability of the iodine because of its alkalinity. Statistical analysis has shown that there was significant difference between iodine concentration in the soils and the drinking water, and a correlation between the soil iodine and organic matter content at p < 0.05. The correlation between soil iodine and granulometric fractions occurred at p < 0.01. Potential goitrogens in the commonly consumed cassava products might also have contributed to the prevalence of goitre in the study area. Both the females and the adults (i.e., less mobile groups) were found to be vulnerable to goitre development in these villages.

Unexpected ultrasonographic prenatal diagnosis of autosomal dominant polycystic kidney disease

The prenatal diagnosis of autosomal dominant polycystic kidney disease (ADPKD) is now being reported with increasing frequency. We report three cases and review 12 cases of ADPKD diagnosed in the fetus by ultrasonographic findings. Increased echogenicity and renal enlargement are the main ultrasonographic signs of ADPKD. Renal cysts are uncommon. Diagnosis is easy in a family with a positive ADPKD history. Conversely, there may be no apparent family history, as in our three cases and three cases from the literature. We consider the problems of unexpected diagnosis, family investigation, and the prognosis of ADPKD in children with prenatally diagnosable forms.

Radiographic,haematological, and biochemical findings in a fetus with Caffey disease

An early case of prenatal Caffey disease is reported. Ultrasound examination performed at 20 weeks showed major angulations of long bones, but both ultrasound scan and X-rays failed to make the differential diagnosis between Caffey disease and lethal osteogenesis imperfecta. A cordocentesis allowed us to find important biological abnormalities. The pregnancy was terminated after the rapid development of hydrops fetalis. The definitive diagnosis of Caffey disease was obtained by special X-ray and pathological study.
