Multiple squamous cell carcinomas of the skin during long-term treatment with hydroxyurea.
Hydroxyurea is a chemotherapeutic agent used extensively for myeloproliferative disorders. Cutaneous side effects have been described during long-term hydroxyurea treatment. We described the occurrence of multiple squamous cell skin carcinomas in a patient treated with hydroxyurea for chronic myelogenous leukemia. The lesions were removed and the hematological therapy switched to busulfan. In a previously reported case, the development of cutaneous epithelial cancers required the discontinuation of hydroxyurea, in addition to the surgical excision of the neoplastic lesions. Since squamous cell carcinoma is a malignant cutaneous neoplasm that can metastatize, the surveillance of skin changes is advisable during hydroxyurea treatment.

Multicystic encephalomalacia in term infants.
The terms "multicystic encephalomalacia" and "subcortical leucomalacia" (SCL) are used to describe the presence of areas of necrosis that develop into cystic lesions inside the brain. These lesions are generally due to severe asphyxia and/or hypotension. The designation SCL can also be used to describe the extent and the seat of the lesion in the brain or to distinguish subcortical lesions from periventricular and/or combined ones. In this study we give an account of our experience with eight newborns admitted to our neonatal intensive care unit, who presented clinical-neurological alterations and encephalomalacic lesions whose presence was documented by ultrasonography.

[Lead concentrations in breast milk of women living in urban areas compared with women living in rural areas].
In the last twenty years a great interest has grown up about the accumulation of lead in the environment, because many studies have found relationship between exposure to low lead doses and neuropsychological impairment of children. The Authors have measured and then compared the lead content of milk from women living in city-areas and women living in rural areas, not having professional lead exposure. 34 samples of women milk from the rural areas and 20 samples from the city areas were examined: the lead mean concentration of the rural areas milk samples was 45.62 microgr/l with a range from 0 to 425 microgr/l; the mean concentration of the city areas samples was 126.55 microgr/l with a range from 1 to 472 microgr/l. The data were compared with the Student t-test and the difference was statistically significant at p = 0.01. The Authors examine the correlations between environmental lead accumulation and increased lead concentration in woman milk, laying stress on the possible hazard to health and neuropsychological development of children, mostly of those living in urban areas with heavy road traffic and industrial activity.

[Osteochondrodysplasia: nosologic assessment and report of 6 clinical cases].
Osteochondrodysplasias represent an important group of disease affecting cartilage and/or bone. The clinical evidence of disarmoniuous low stature, of a disproportion between trunk and limbs length, of a big skull can suggest this diagnosis and the necessity to carry out all the instrumental investigations. The diagnostic suspect can be placed, some time, already in the neonatal period. The complexity of problems regarding the osteochondrodysplasias bearer child and his family requires a multidisciplinary approach. The Authors present a personal experience of six cases of osteochondrodysplasias observed in a period of fifteen years.

[An ovarian mass in childhood: a case report].
Ovarian tumors are a very heterogeneous group of neoplasms that rarely occur in pediatric age. When it happens, they are usually very malignant germ cell tumors such as embryonal carcinoma, endodermal sinus tumor or choriocarcinoma. We describe a case of a 14 years old girl who came to our observation because of an abdominal enlargement without others symptoms. The abdominal palpation revealed a big, round, painless mass from pelvic to epigastric region. A specific and accurate diagnosis was made by ultrasound. The histological examination of the surgical removed mass revealed a mucous cystadenoma that's a benign epithelial ovarian tumor.

[The lead concentration in the converted and special-formula milks used in infant feeding].
In the last years a strict correlation between chronic exposure to low lead doses and neuropsychological impairment in first childhood is often reported in literature. The authors have measured and than compared the lead content of milk-based formulas, of special-formulas (hypoallergenic-protein formulas, lactose-free formulas, proteic-hydrolysate formulas) and soya formulas. 20 samples of milk-based formula, have been measured along with, 22 samples of special formula and 14 samples of soya formula. Lead mean concentration in milk-based formula was 73 +/- 139.11 microgr./l, whereas 23.95 +/- 13.76 microgr./l and 22.57 +/- 13.42 were measured in special formula and soya formula respectively. These results were compared with Student t-test and no significative difference was found. Lead mean concentration of milk-based formula was higher than that of special formula or soya formula. The authors hope milk-formula industry to have a more specific control on lead milk content for children feeding. In order to avoid possible toxic injuries in little infants, industry should certainly pay more attention both in supplying and in technological management of milk.

Follicular mucinosis successfully treated with isotretinoin.
We describe the case of a 33-year-old Caucasian male with follicular mucinosis successfully treated with isotretinoin. Follicular mucinosis is a primary idiopathic disease or a secondary, lymphoma-associated dermatosis. An effective standard therapy for this disease is unknown. In our case, isotretinoin led to a dramatic improvement of the skin lesions in about two weeks. To the best of our knowledge, the benefits of isotretinoin in the treatment of follicular mucinosis have never been reported previously. The efficacy of this drug could be mediated by a regulatory effect on the infiltrating cells and/or by a modulation of the target organ (skin) response to the infiltrating cells.
