We investigated the morphology of the scalp hair shaft from the base to the distal end of the newborn hair and the ratio of the longitudinal axis diameter of the scale exposed to the surface of the hair to the diameter of the hair by scanning electron microscopy(SEM). Neonatal hair was observed to taper from the area adjacent to the scalp toward the end of the hair. In this study, as the thickness of the hair increases, the ratio of the long axis diameter of the exposed scale becomes relatively small, but the long axis diameter of the exposed scale on the surface of the hair is similar in length regardless of the thickness of the hair. In conclusion, it was confirmed that the major axis diameter of the scales exposed to the surface of fine or thick hair does not change significantly.

Netherton's syndrome is an unusual disorder which consists of triad of ichtyosiform dermatosis, multiple defects of hair shaft and an atopic diathesis. The finding of bamboo hair is pathognomic in Netherton's syndrome and the ichthyosiform dermatosis may consist of either ichtyosis linearis circumflexa or congenital ichthyosiform erythroderma. Often, variability in the clinical features leads to a delay in diagnosis in many cases. We report a case of Netherton's syndrome diagnosed in the neonatal period. The patient presented with severe ichthyosis and confirmed microscopically distinctive bamboo hair.

A diagnosis of iodine-deficient goiter was confirmed in newborn piglets that were born hairless edematous, and with markedly enlarged thyroid gland. Clinically, most of the piglets were born dead, extreme weakness or dying within a few hours of birth. Gestation periods were prolonged for 3-7 days. Histopathologically, hair follicles were scarce and reduced in size, contained slender hairs, and revealed a shallow penetration into the hypodermis that showed severe diffuse edema. Thyroid glands had severely hyperplastic follicles and poorly staining colloid. The follicles were irregular in size and shape depending on varying amounts of lightly eosinophilic and granular colloid in the lumen. The iodine content of the diet fed to the sows and plasma total thyroxine and triiodothyronine concentration of sows were very low. This is a first report for iodine-deficient goiter in newborn piglets in Korea.

Serum levels of human placental lactogen have been measured by hemagglutination-inhibition reaction in 67 normal pregnant state and in 15 postpartum 24 hour state, HAIR is less sensitive and reliable method than radioimmunoassay, but simple, rapid, less expensive and fairly accurate, so it is more helpful in screening of large antenatal population with or without high risk complications. 1) Sensitivity of HPL-HAIR test kit was $0.1{\mu}g$/ml of H.P.L. serum level and had no cross reaction to HCG or male serum or non-pregenant female or newborn infant, 2) H.P.L. value was around $2{\mu}g$/ml until 24th week of pregnancy and rose to $6{\sim}8$ ${\mu}g$/ml continuously until about 36th week of pregnancy and then slightly decreased or stationary. 3) H.P.L. value in postpartum 24 hour state was undetectable. 4) There was poor correlation between maternal serum H.P.L. value at term and baby weight.

Klinefelter syndrome is the most common chromosomal abnormality, with a 47, XXY karyotype and typical clinical findings of infertility, hypogonadism, reduced body hair, gynecomastia, tall stature, and incresed gonadotropins and decreased testosterone levels. In addition to this classic description, several other diseases have been discribed in Klinefelter syndrome such as unilateral renal aplasia, autoimmune disease, diabetes mellitus, sexual precoxity, renal cell carcinoma, intravesical ureterocele, and osteoporosis. The incidence is 1 in 400-1,000 of the population and urological abnormalities are not common. However a case of Klinefelter syndrome associated with multicystic dysplastic kidney has not been not reported up to date. Therefore, we describe a 1-day-year old baby boy who presented with Klinefelter syndrome with unilateral multicystic kidney dysplastic disease, plus with a brief review of the literature.
