Successful pregnancy and delivery after simultaneous islet-kidney transplantation.

Allogeneic islet of Langerhans transplantation is a recognized beta-cell replacement therapy for patients affected by type 1 diabetes mellitus. Type 1 diabetes mellitus is a condition associated with an increased risk of adverse outcomes for pregnant women and fetuses. We report the case of a 29-year-old woman with type 1 diabetes mellitus, who underwent successful allogeneic islet transplantation with simultaneous kidney transplantation.

[The role of thyroid ultrasonography in the diagnostic approach to thyroid diseases].

Echography is of increasing importance and is considered of value in the diagnostic approach to thyroid diseases. It is particularly useful for assessment of precise measurements of the thyroid gland and to the clinical physician when he has to judge the benign or malignant nature of nodular lesions, as a complement to fine-needle aspiration-biopsy.

Corrosion behavior of nickel-containing alloys in artificial sweat.

The corrosion resistance of various nickel-containing alloys was measured in artificial sweat (perspiration) using the Tafel extrapolation method. It was found that Ni, CuNi 25 (coin alloy), NiAl (colored intermetallic compounds), WC + Ni (hard metal), white gold (jewelry alloy), FN42 and Nilo Alby K (controlled expansion alloys), and NiP (electroless nickel coating) are in an active state and dissolve readily in oxygenated artificial sweat. By contrast, austenitic stainless steels, TiC + Mo2C + Ni (hard metal), NiTi (shape-memory alloy), Hastelloy X (superalloy), Phydur (precipitation hardening alloy), PdNi and SnNi (nickel-containing coatings) are in a passive state but may pit under certain conditions.

The effect of rectal and nasal administration of salmon calcitonin in normal subjects.

In order to ascertain the blood levels and the biologic responses obtained after administration of two noninjectable forms of salmon calcitonin (SCT) (i.e., a nasal spray and a suppository), two doses of 200 IU each were administered at 3 hour intervals nasally to 8 normal subjects, and rectally to 9 normal subjects.
