Erythema elevatum diutinum associated with celiac disease: response to a gluten-free diet.

An 11-year-old girl with a history of insulin-dependent diabetes mellitus had erythema elevatum diutinum (EED) associated with a celiac disease related to a possible kidney disease. Dapsone did not improve the skin manifestations. However, the lesions disappeared after a gluten-free diet was begun. To our knowledge, this report describes the first case of EED in a patient with celiac disease.

Seasonal variations in plasma luteinizing hormone and testosterone levels in the European badger Meles meles L.

Although active spermatogenesis occurs throughout the year in the male European badger Meles meles L., seasonal fluctuations of testicular activity were observed. The present study compared the pattern of luteinizing hormone (LH) and testosterone (T) secretions throughout the annual cycle. LH secretion was investigated by means of a heterologous radioimmunoassay using anti-ovine LH beta antiserum and canine reference standard. Seasonal and nycthemeral changes in LH and T secretions were observed. During the year a period of maximal values for both hormones is well correlated with the breeding. Moreover, episodic LH releases occurs during the period of minimal testosterone values, indicating resumption of hypothalamo-pituitary activity well before the breeding period.

[Diagnostic errors in nephroblastoma].

We review 37 patients diagnosed of Wilms' tumor at the Clinica Infantil "La Fe", in the last ten years, looking at the misdiagnosed cases. In two children, histological study showed a multilocular renal cyst. We also report a case previously diagnosed as being a multicystic kidney; the histological study revealed, however, a cystic partially differentiated nephroblastoma. No case of extrarenal tumors was present in the misdiagnosed patients. We comment the difficulties to make a correct diagnosis when confronted with the above mentioned entities and before histological data are available.

[Pharmacologic evaluation of penicillin in children with meningococcal meningitis].

Levels of penicillin both in blood and CSF are determined in 11 children with meningococcal meningitis. Authors compare these values with MIC. The therapeutic pattern was 500.000 Ul/Kg/day of benzylpenicillin, in six doses, with a single initial doses of 200.000 Ul/Kg. The results recommend not to use a lower doses in order to assure a permanently efficient penicillin concentration.

Plasma progesterone levels during delayed implantation in the European badger (Meles meles).

There was a biphasic pattern of progesterone secretion during the year. Delayed implantation was characterized by low concentrations from February to June, a significant (P less than 0.001) increase during July, August and September, and a return to low levels in October-November. A second significant increase (P less than 0.001) was observed in December and early January just before the presumed time of implantation.
