INTRODUCTION
The traditional practices of topically treating dermatological conditions with plant-derived medicines predate the cultures of ancient Egypt and remain vital today in the industrialized cultures of both the United States and Europe. Recent scientific studies lend support to some of the claims of herbal practitioners for the safety and efficacy of many herbal remedies. Dermatologists are largely unfamiliar with herbal remedies and may harbor some misconceptions.

RVT is a clotting process that originates in the venous radicles and progresses into the main renal vein and vena cava. In Germany, the minimum incidence of symptomatic neonatal RVT between 1992 and 1994 was 2.2 per 100,000 live births. Zigman et al reported an incidence of 2.3 cases/year in Canada. Review of the literature in PubMed, African Journal online and Embasse showed no reports from Africa and Japan.

UN is a two-hour-old male admitted into the Special Care Baby Unit (SCBU) of the University of Port Harcourt Teaching Hospital, Port Harcourt, Nigeria due to macrosomia, birthweight of 4.6 kg. He was the fourth child of a mother who had one other live child and two miscarriages (para Г mother). He was delivered by normal vertex after a 40-week gestation. The pregnancy was initially supervised in a private clinic from two months until eight months and thereafter in our hospital. She developed glycosuria at six months of gestation; however, the fasting blood sugar was normal (FBS 4.6 mmol/L). The mother was not a known diabetic and had no family history of diabetes. Her first delivery was a male weighing 4.2 kg at birth. There was no gestational diabetes in that pregnancy. There was a positive history of big babies in the mother’s family. Her younger sister delivered a third child who weighed 5.2 kg.

INTRODUCTION
Renal vein thrombosis (RVT) is a multifactorial disease that predominantly affects newborn infants. It may follow maternal diabetes, asphyxia, hypertonic dehydration, congenital heart disease, acute blood loss, shock, presence of an indwelling umbilical venous catheter and sepsis. A review of the literature showed that RVT of the newborn might be of unknown etiology and probably occurs before birth. Genetic mutations, such as factor V Leiden, is a risk factor especially for in utero RVT. Other risk factors include prolonged central venous cannulation, hereditary thrombophilia, trauma, burns, and Wilms tumor. In the adult and children it is often a silent complication of the nephrotic syndrome, the hypercoagulability of which may be an important factor in the pathogenesis of the thrombosis.

The expansion of Medicaid and the creation of SCHIP between 1997 and 2002 effectively increased public health insurance coverage of both children and adults. Uninsurance rates were reduced significantly for black, Hispanic and white children in low-income families. Black and white adults experienced no change in uninsurance during this period. The share of Hispanic adults without health insurance, however, increased significantly. Compared to black or white adults, Hispanic adults gained less in the expansion of public coverage, for which many Hispanic adults were (or believed themselves to be) ineligible due to restrictions on benefits for nonciti-zen immigrants. Hispanic adults were also the only group to see a drop in employer-sponsored coverage. Immigrants are less likely to be offered employer-sponsored health insurance than native-born workers, and the proportion of Hispanic adults born outside the United States increased during this period.

Public health insurance coverage of adults rose by about one percentage point between 1997 and 2002 (Table 2). Despite this gain, the proportion of adults without health insurance was 17.0 in each year. Hispanic adults did not share in the overall increase in public coverage and were the only group to experience a decline in employer-sponsored health insurance. Consequently, uninsurance among Hispanic adults rose by four percentage points between 1997 and 2002, pushing their already high uninsurance rate to 40.7%.

To measure health insurance coverage, the NSAF asks about multiple sources of coverage and follows with a verification question to confirm lack of coverage among those who do not identify a source. Coverage is measured at the time of the survey, defined using a hierarchy, and then grouped into four categories: employer-sponsored insurance (including coverage through the military); Medicaid, SCHIP or another state program; other (including coverage through private insurance, Medicare or other coverage of an unspecified type); and uninsur-ance. The estimates presented here differ slightly from those presented in the work of Zuckerman and Kenney, Haley and Tebay, which include 18-year-olds as children and not as adults.
