Systemic lupus erythematosus and strongyloidiasis: a multifaceted connection.

We describe a case of systemic lupus erythematosus complicated by strongyloidiasis. The parasitic infection appeared with diarrhoea, weight loss and peripheral eosinophilia in association with recurrence of polyarthritis, probably due to a flare of systemic lupus erythematosus. The literature about the coexistence of systemic lupus erythematosus and strongyloidiasis has been reviewed.

Moderate coffee consumption increases plasma glutathione but not homocysteine in healthy subjects.

BACKGROUND: The consumption of unfiltered coffee, containing bioactive diterpenes, causes an increase in plasma homocysteine concentration. A slight increase in plasma homocysteine is also caused by large quantities of filtered coffee. Coffee terpenes also raise plasma glutathione in mice. AIM: To verify the effect of Italian-style coffee consumption on the plasma concentration of glutathione and homocysteine in healthy subjects. METHODS: Twenty-two volunteers consumed five cups of coffee per day for 1 week and maintained their usual diet. Five subjects were enrolled as controls. The intervention trial was preceded and followed by seven coffee-free days. RESULTS: Plasma glutathione increased by 16% (P < 0.05) on coffee consumption, and returned to the original concentration after the washout period. The increase in plasma homocysteine concentration (13% after 1 week of coffee intake) was not significant. No differences in glutathione or homocysteine concentration were observed in the control group. No variation of plasma hydroperoxide concentration was detectable. CONCLUSIONS: A coffee intake regimen, representing the average consumption of coffee drinkers in Italy, increased the plasma concentration of glutathione, but no significant increase in the plasma homocysteine concentration was detected.

Non-alcoholic fatty liver disease in an area of southern Italy: main clinical, histological, and pathophysiological aspects.

BACKGROUND/AIMS: Studies on non-alcoholic fatty liver disease (NAFLD) have included chronic liver damage attributed to various causes. Our investigation was held to observe the main clinical, histological, and pathophysiological aspects of NAFLD in patients not exposed to any known cause of chronic liver disease. METHODS: We evaluated, in 84 in-patients (male/female, 66/18; median age, 36 years), the clinical and biochemical characteristics of NAFLD, and particularly its association with diabetes, dyslipidemia, hyperinsulinemia and/or with the increase of parameters of oxidative stress (blood levels of malonyldialdehyde, 4-hydroxynonenal and total plasma antioxidant capacity). RESULTS: Ninety percent of patients had an increased body mass index (BMI), 35% had dyslipidemia, 40% had sub-clinical diabetes (only 3% had overt diabetes), 60% had hyperinsulinemia, and more than 90% had enhanced levels of lipid peroxidation markers. In 48 patients who had consented to liver biopsy, we found: 14 with simple steatosis, 32 with steatohepatitis, and two with cirrhosis. CONCLUSIONS: Our data indicate that in our country, NAFLD may occur in young males with an increased BMI, with or without hyperinsulinemia, dyslipidemia and diabetes, generally associated with disorders of redox status, and that it may be differentiated from steatosis to steatohepatitis or cirrhosis only with a liver biopsy.

Bone age delay in Perthes disease and transient synovitis of the hip.

Patients with transient synovitis of the hip were found to have a bone age delay similar to the one found in patients in the active stages of Perthes disease. This finding led to a study on the relationship between the bone and chronologic ages in patients affected by either disease, in activity, and in the residual stage through to the end of growth. Bone age of all patients was established by means of a radiograph of both wrists and hands and the quantified data were compared with the Greulich and Pyle Atlas. All the patients in the active stage of both diseases revealed a bone age delay with different values and different time evolution but with some degree of overlapping between the thirtieth and seventieth months of age. The bone age delay persisted after healing of the respective disease and tended to diminish with time in an erratic way until the age of puberty when the bone and chronologic ages assume similar values. Transient synovitis of the hip usually occurs in only one hip.

Method for measuring antioxidant activity and its application to monitoring the antioxidant capacity of wines.

A novel method for measuring the antioxidant activity using N, N-dimethyl-p-phenylenediamine (DMPD) was developed. The radical cation of this compound gives a stable colored solution and a linear inhibition of color formation can be observed in the presence of 0. 2-11 microg of TROLOX. The experimental protocol, which is rapid and inexpensive, ensures sensitivity and reproducibility in the measure of antioxidant activity of hydrophilic compounds. The effectiveness of the DMPD method on real foods was verified by evaluating the antioxidant ability of wine samples coming from different areas of Campania, Italy. Antioxidant capacity of wines is strictly related to the amount of phenolic compounds. The results obtained by the DMPD method are very similar to those obtained on the same samples when the radical cation of 2, 2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) (Miller et al., 1996) was used.

Kabuki make-up (Niikawa-Kuroki) syndrome: clinical and radiological observations in two Sicilian children.

The Authors describe two patients aged 5 and 8, a female and a male, affected by a condition of polymalformations known as Kabuki make-up or Niikawa-Kuroki syndrome, having a neonatal incidence of 1:32,000 in Japan. There are two hypothesis about the apparent rarity of the syndrome in the rest of the world, including the Asian Continent: the first is that it exists, but is infrequently recognized outside Japan and the second is that it is really more frequent in those parts of the world, where ethnic exchanges are uncommon, as it happens in Japan.

Congenital dislocation of the knees--report on two cases treated without surgery and a review of the literature.

The author reports on two cases of congenital dislocation of the knees submitted to orthopaedic treatment. The early treatment and the relatively benign nature of the main deformity and of the associated phenomena appear to have contributed to the excellent results obtained after a six year follow-up. A review of the literature on the subject is given.

Value of the head-at-risk concept in assessing the prognosis in Legg-Calvé-Perthes disease.

Seventy-five hips affected by Legg-Calvé-Perthes disease were reviewed. Three therapeutic groups were defined: conservative treatment, marrow emptying of the femoral neck, and varus derotation femoral osteotomy. Results were analyzed according to head-at-risk concept. Patients with head not at risk had better results regardless of treatment. Results in other groups were worse, but improved significantly with varus derotation femoral osteotomy. In children greater than 9 years of age, the results were almost invariably poor, irrespective of head-at-risk designation.
