Familial tyrosinaemia with eye and skin lesions. Presentation of two cases.
Two cases of tyrosinaemia with eye and skin lesions typical of the Richner-Hanhart syndrome are described. The patients are a 29- and 26-year-old brother and sister. They do not show neurological abnormalities or mental retardation. Parents are not consanguineous and family history is negative for similar conditions. The diagnosis of type II tyrosinaemia was based upon an increase of blood tyrosine (14-16mg/100 ml), tyrosinuria and absence of liver and kidney abnormalities. The treatment with a low tyrosine phenylalanine diet has resulted in a disappearence of the ocular manifestations while the cutaneous lesions are much improved.

A basis for estimation of consumption: literature values for selected food volatiles. Part I.
This paper is a compilation of quantitative data available on volatile compounds reported so far in 18 food items including some legume, cereals, grapes and cheeses as well as crab, lobster, cocoa and chocolate. No publications reporting quantitative data were found for five of these 18 food products, i.e. sultana grape, broad beans, cassava, oat and rye. About 440 volatile compounds have been assayed globally in the other 13 food products and more than 50% of them were found in grape or in grape juice. Levels of these volatile compounds in the selected foods were generally in the ppb range and less often in the low ppm range. Very high levels were found for some carboxylic acids in cheeses and cocoa and for some alcohols and acids as well as for ethyl acetate in grape juice.

A basis for estimation of consumption: literature values for selected food volatiles. Part II.
In this paper we present a compilation of quantitative literature data on volatile compounds in 15 food items including some brandies, meats, oils as well as vegetables, vinegar and potatoes. Levels of the volatile compounds identified (approximately 900) in this group of food items are generally in the ppm range. Carboxylic acids were present in much higher levels in plum brandy, vinegar, lamb and mutton (heated), whereas alcohols, esters and carbonyls aldehydes are particularly abundant in brandy.

Use of drugs among street children in Brazil.
The purpose of this study has been to assess drug consumption among children in five Brazilian state capitals during 1993. The sample was composed of street children who were given assistance in institutions, and data was collected by means of anonymous individual interviews. Five hundred sixty five boys and girls were interviewed: 74.3% reported having used drugs (not including alcohol and tobacco) at least once in their life. Solvents, followed by marijuana, were the most cited drugs. Important regional differences were observed concerning other drugs. Consumption of cocaine, including crack, seems restricted to the southeast region, whereas psychotropic medication was consumed more in the northeast of the country. Drug initiation among these children seems to be a consequence of street life and is part of their group lifestyle.

A study of the pharmacological actions of Dioclea grandiflora Martius ex Bentham.
Dioclea grandiflora Mart. ex Bent., known as Mucuna or Mucuna of stone, is a member of the Leguminosae family, popularly used for its possible effects on the Central Nervous System (CNS). Reports mention sedative, tonic, and also antiepileptic properties for this plant. In this paper a screening for CNS action was done with aqueous extracts of the seeds. This study was carried out using some animal models for the study of sedative, hypnotic, anxiolytic, anticonvulsive and neuroleptic activity. The results showed that Dioclea grandiflora Mart. ex Bent. demonstrates the general profile of a CNS depressant drug. However, the extract did not exhibit any of the specific profiles tested. Moreover, the results suggest a possible toxicity stemming from the popular or folk use of this plant.

Laparoscopic decapsulation of a large epidermoid splenic cyst in a child using the UltraCision LaparoSonic Coagulating Shears.
Splenic cysts are rare in pediatric surgery. Congenital epidermoid cysts are exceptional representing only 2.5% of all splenic cysts in childhood. Nowadays, considering the short- and long-term complications of splenectomy in children, the management of epidermoid cyst consists of partial splenectomy or decapsulation of the cystic wall. To our knowledge, the case reported in this article describes the first successful laparoscopic decapsulation of an epidermoid splenic cyst in an 10-year-old child using the UltraCision LaparoSonic Coagulating Shears (LCS). Follow-up at six months confirms no recurrence. Laparoscopic splenic decapsulation provides minimal access and small surgical trauma for treating the cyst while preserving splenic function. The use of UltraCision LCS makes the laparoscopy safely, expeditiously, with minimal blood loss and short hospital stay.

Initial experience with laparoscopic adrenal surgery in children: is endoscopic surgery recommended and safe for the treatment of adrenocortical neoplasms?
Through a review of 83 cases reported in literature, including our experience of two successful right laparoscopic adrenalectomies performed in a 3-year-old girl for androgen-secreting adenoma and in a 9-year-old male for pheochromocitoma, we have anaIyzed the indications, the techniques and the results of laparoscopic or retroperitoneoscopic adrenalectomy in children. Nineteen pheochromocytomas, 18 neuroblastomas, 15 adenomas, 12 ganglioneuromas, 9 hyperplasias, 2 carcinomas, 1 teratoma and 1 adrenogenital syndrome have been treated with excellent results (follow-up 1 month to 4 years) with no evidence of recurrence. The age range is from 1 month to 16 years with an equal female/male ratio. The tumor size range from 10 mm to 80 mm with approximately a mean of 40 mm. Sixty-three laparoscopies of which 54 lateral and 9 anterior have been performed versus 14 posterior retroperitoneoscopies. Regarding right adrenalectomy, 29 were laparoscopic and only 2 retroperitoneoscopic. With regards to left adrenalectomy, 23 were laparoscopic and 9 retroperitoneoscopic. Looking at bilateral lesions, these tumors were approached laparoscopically in 6 cases alternating both sides and 1 retroperitoneoscopically (this case was already operated on the other side). The operative time ranged from 25 minutes in newborn to 320 minutes in bilateral cases with an average of 120 minutes. Conversion rate is higher in retroperitoneoscopy (30%) (4 cases out of 13), than laparoscopy (6%) (4 cases out of 63). Specifically, for right retroperitoneoscopic adrenalectomy conversion rate was 100% (2 cases out 2), for left retroperitoneoscopic adrenalectomy 22.2% (2 cases out 9), for right laparoscopic adrenalectomy 6.8% (2 cases out of 29) and for left laparoscopic adrenalectomy 8.6% (2 cases out of 23). Only in 1 case were blood transfusions requested. Hospital stays ranged from 35 hours to 17 days with an average of 4 days. In conclusion the indications of endoscopic adrenalectomy in children are not different from those of traditional surgery and the well-known advantages of laparoscopic adrenal surgery should be applied to pediatric patients. It seems that there is no age and tumor size limits for a well-trained surgical team. Lateral transperitoneal approach is the most utilized with the child positioned in 90-degree flank decubitus. Laparoscopy is undoubtly preferred for right adrenalectomy (93% of cases), while for left adrenalectomy retroperitoneoscopy has been used in 39% of the cases. Considering the conversion rate and on the basis of our experience with adults, we recommend laparoscopic adrenalectomy for both right and left adrenal lesions, but we think that the pediatric surgeon should feel free to choose the approach in which he/she is more skilled. However, the best surgical result will be achieved if the pediatric and adult surgeon collaborate with their different experiences. Lastly, we suggest the use of new technological devices such as Ultracision Harmonic Scalpel which was a critical factor in our two successful right adrenalectomies.

Insulin glargine in patients with severe hepato-gastroenterology diseases and hyperglycemia receiving parenteral nutrition.
OBJECTIVE: The aim of this nonrandomized observational study is to verify and confirm whether it is possible to use insulin glargine (Lantus) subcutaneously in patients receiving parenteral nutrition (PN) and whether the analogue is capable of obtaining and maintaining good glycemic control without inducing hypoglycemia. MATERIALS AND METHODS: The sample is made up of 25 patients with severe hepato-gastroenterology diseases receiving parenteral nutrition, diagnosed diabetics and non-diabetics, who had previously been prescribed traditional insulin therapy. All were to be given subcutaneous insulin glargine at a dosage equal to the average of insulin/day administered in the preceding days spent receiving PN. RESULTS: Twenty-five consecutive patients, not stratified in any way, were judged eligible in the last six months of 2004 and first eight months of 2005. Four out of these 25 cannot be evaluated, either because (2/4) they did not begin or complete the treatment with Lantus or because the proper number of glycemic tests were not done (2/4); 21/25 patients, 84% of the sample with a mean age of 65.9 years (range 46-93 yr), finished the study and can be evaluated. The mean glycemic values after treatment with glargine were already better on the second day, and on the seventh day the difference was statistically significant. No hypoglycemias occurred which required medical intervention. CONCLUSIONS: This study confirms the possibility of using insulin glargine in patients receiving parenteral nutrition with hyperglycemia diagnosed diabetics or not diabetics.

[Sensitivity and specificity of antigliadine antibodies in the diagnosis of celiac disease in a population of children in Toscana].
The aim of this study was to determine the value of IgA and IgG antigliadin antibody test (AGA) for screening, diagnosis and follow-up of coeliac disease. A rapid, simple, sensitive and accurate immunosorbent assay (ELISA) was used to determine AGA IgA and IgG in the sera of patients with untreated coeliac disease (I stage), coeliac patients in gluten withdrawal, healthy controls, children with gastroenterological disorders other than coeliac disease and children with constitutional short stature. In the I stage of coeliac disease the AGA IgA gave a sensitivity of 90.9% and a specificity of 97.9%, the IgG assay resulted in a sensitivity of 100% and a specificity of 82.3%. AGA IgG resulted positive in 17.7% of control disease group, but it's interesting to remark that they had a mean level significantly lower than in coeliac patients. On gluten free diet the titres of AGA IgA returned to normal value in three months, while the AGA IgG showed a slower decrease.

[Hemolytic group B streptococcus in cervico-vaginal secretions].
The group B streptococcus can be an etiological agent of newborn's infections and vaginitis. Therefore, we evaluated the statistical incidence of this microorganism in vaginal swabs of 1403 non-selected subjects. We isolated this streptococcus in 12.3% samples and it was present in 26.3% of positive cultures. Our study confirms the elevate incidence of this microorganism and suggests the opportunity of this research in pregnancy monitoring and in gynaecological flogosis.

[Results of a screening project for congenital hypothyroidism in 4 years of experience].
A screening program for congenital hypothyroidism has been starting in Siena since November, 1977 with the Guthrie's test for PKU. According to the recommendations of the Committee of the European Thyroid Association the program were performed on capillary blood samples collected between the fourth and sixth days after birth on an adsorbent paper. The screening began with the measurement of T4 RIA (up to May, 1980), and T4 and TSH RIA (from may, 1980, to december, 1981). At december, 1981, 23.693 newborns have been screened. The recall rate was 2,5% up to may, 1980, and 0,11% from may, 1980 to december, 1981. Ten newborns with congenital hypothyroidism have been detected; the incidence is one in 2.400 live births. There were no cases of transient hypothyroidism and no cases of TBG deficiency. All patients are treated before the age of one month. The diagnosis is confirmed in seven cases at one year of life after stopterapy for one month. Our program confirm the high incidence of congenital hypothyroidism. Clinical control, based on physical and psychomotor development testing in seven patients treated confirmed that all infants are normal.

[Empty sella syndrome: a cause of GH deficiency?].
A deficiency of growth hormone (GH) was detected in a male child with "empty sella syndrome" (ESS). Association between ESS and defeciences of pituitary hormones has been previously reported in adult subjects. It seems likely that GH deficiency is be related to ESS in the case described in this paper. An appropriate evaluation of the endocrine system seems suitable in this condition, since ESS in childhood is not to be regarded only from neuroradiologic point of view.
