Integration of monitoring and motor-training units for a tele-rehabilitation service.

A tele-rehabilitation system has been designed for general use. The service can extend the rehabilitation treatment of patients affected by neurological diseases such as stroke or multiple sclerosis to their home, while under the control, supervision and responsibility of a hospital. Part of the initial work involved identifying the functional blocks of a tele-rehabilitation service. There are three parties involved in the tele-rehabilitation service: the health provider (the central unit of the system), the health operator (the medical unit of the system, generally a therapist) and the home platform (a central console with a high level of modularity). Tele-rehabilitative services that are easy to use could radically change the routine care and rehabilitation process.

Ocular changes associated with Giardia lamblia infection in children.

BACKGROUND: The protozoan disease giardiasis can cause ocular complications, including "salt and pepper" retinal changes. METHODS: Ophthalmic examinations were performed in 141 children (mean age 4.7 (SD 2.0) years) with active or past giardiasis diagnosed on the basis of microscopic examination of stool specimens or duodenal secretions--53 were newly diagnosed and untreated (group A), 50 had active infections in spite of metronidazole therapy (group B), and 38 had been successfully treated, with negative stool specimens for 1-3 years (group C). 300 children with no evidence of giardiasis were used as controls. RESULTS: Salt and pepper retinal changes (with normal electroretinographic findings) were diagnosed in 28 (19.9%) of the patients with giardiasis (11 from group A, 10 from group B, and seven from group C), including five pairs of siblings. In all subgroups, the children with retinal changes were consistently younger than those with normal retinas. In eight cases, the lesions could be visualised only with direct ophthalmoscopy. CONCLUSION: Our findings indicate that asymptomatic, non-progressive retinal lesions are particularly common in younger children with giardiasis. This risk does not seem to be related to the severity of the infection, its duration, or the use of metronidazole but may reflect a genetic predisposition.

[Clinical comparison of different replacement milk formulas in children with allergies to cow's milk proteins. 24-month follow-up study]. / Comparazione clinica di differenti formule di latte sostitutivo in bambini con allergia alle proteine del latte vaccino. Follow-up a 24 mesi.

The elective treatment for allergy to cow's milk protein is the elimination of these proteins from the diet. The present study with a follow-up of over two years took the form of a comparison between different replacement formulas based on soya (group A), hydrolysate of soya and bovine collagen (group B), and hydrolysate of casein (group C), randomly administered to 55 children (30 males and 25 females, aged between 2-48 months) with documented allergy to cow's milk proteins, but with different clinical symptoms. Tests to evaluate the acquisition of clinical tolerance to cow's milk proteins were performed using a day-hospital regime every 6 months. Sensitivity reactions were observed in 22% of cases in group A, 8% in group B and 37.5% in group C. It is worth underlining that 5 of the 6 children with reactions to soya protein then showed an excellent tolerance to hydrolysate of soya when it was administered subsequently until tolerance was achieved. Weight and statutory growth was uniformly good in all three groups. A high percentage of children achieved tolerance after 24 months (72%); the mean time taken to acquire clinical tolerance was 11.6 +/- 4.8 in group A, 11.6 +/- 6.02 in group B, and 14 +/- 5.6 in group C. No correlation was found between the type of initial symptoms, age at onset, method of response to first challenge and the time taken to acquire tolerance.

Analysis of polyunsaturated fatty acids in newborn sera: a screening tool for atopic disease?

It has been demonstrated that patients with atopic disease have anomalies of fatty acid composition, as a result of altered metabolism or abnormal incorporation of fatty acids into the tissues. In the present study, in 57 newborns 'at risk' for atopic disease, the polyunsaturated fatty acid (PUFA) levels were found to be lower in cord blood in infants who subsequently developed atopic disease than in non-atopics. In all babies, levels of arachidonic acid and dihomo-gamma-linolenic acid in sera at 1 and 3 months of age were lower than those in cord blood. These changes were more marked in children who subsequently developed atopic disease, and in those who, independently of signs and/or symptoms of atopic disease, were formula-fed. A comparison between IgE and PUFA levels revealed no significant differences at any tested time interval. In conclusion, our data suggest that in children 'at risk' for atopy, PUFA levels may be predictive of atopic disease.

Methylprednisolone bolus: a novel therapy for severe atopic dermatitis.

Seven children suffering from severe atopic dermatitis, unresponsive to standard therapy, received an iv bolus dose of methylprednisolone (20 mg/kg/day) for three days. Immunological parameters were evaluated before and after treatment. At the end of bolus therapy both skin lesions and itching improved for several months in five of seven patients. No side effects were observed, but a significant and transient lymphopenic response occurred, with lower CD4+ than CD8+ lymphocyte counts. Our data suggest that this therapy may be a novel and safe therapeutic approach in severe atopic dermatitis.

Value of the 24 hour intraoesophageal pH monitoring in children.

Twenty four hour oesophageal intraluminal pH probe studies were performed in 114 children (range age: one month-12 years) referred for symptoms or signs compatible with gastroesophageal reflux. Forty five patients had reflux disease alone, 69 had evidence of oesophagitis which was assessed endoscopically and histologically. Recordings were also performed in 63 control patients. The occurrence of reflux was analysed for the total study period and particularly while awake, asleep, fasting, and during postcibal periods. Oesophageal acid exposure time and the number of reflux episodes lasting greater than five minutes during the total study period provided the best discrimination between patients and controls; however, 20% and 30% of all reflux patients had both normal (with 2 SD of control) acid exposure time and number of long lasting reflux episodes, respectively. Patients with oesophagitis had significantly more acid reflux than those with simple uncomplicated disease during postcibal, fasting, awake periods, but not during sleep; however, increasing severity of oesophagitis was not associated with increasing acid exposure. The ability of the intraluminal oesophageal pH test to discriminate patients with various degrees of reflux disease decreased if only postprandial pH variables were taken into account. We conclude that: (1) the 24 hour intraoesophageal pH monitoring may present false negative results that limit overall sensitivity of the test; (2) the presence of oesophagitis does not seem to be associated with increased oesophageal acid exposure during sleep; (3) limiting the pH recording to postprandial periods reduces the discriminatory power of the test.

Effects of cisapride on parameters of oesophageal motility and on the prolonged intraoesophageal pH test in infants with gastro-oesophageal reflux disease.

The effect of cisapride, a new gastrointestinal prokinetic drug, on oesophageal motility and acid reflux was studied in 14 children with gastro-oesophageal reflux disease, receiving either placebo or cisapride 0.15 mg/kg intravenously. Cisapride significantly (p less than 0.01) increased the lower oesophageal sphincter pressure (+124%), the amplitude (+84%) and duration (+24%) of oesophageal peristaltic waves, whereas the placebo treatment did not produce any changes. Subsequently, all 14 children underwent 24 hour oesophageal pH-monitoring before and after four weeks of treatment with oral cisapride 0.2 mg/kg tid given in addition to postural therapy and thickened feedings. The 24 hour intraoesophageal pH recordings and symptomatic scores were compared with those of 10 control patients treated only by postural therapy and thickened feedings. When compared with baseline pH data, cisapride significantly reduced the oesophageal acid exposure time, the mean duration of each reflux episode, the duration of the longest reflux episode and the number of long lasting reflux episodes; the number of reflux episodes was not influenced. The effect of cisapride was marked and consistent during fasting and sleep periods. Oesophageal acid exposure was reduced more significantly in patients given cisapride (-61%) than in controls (-24%; p less than 0.001). Symptom improvement was greater after four weeks of cisapride treatment (score reduction: 61%) than after postural and dietary therapy alone (score reduction: 42%; p less than 0.01). No adverse effects occurred. These findings suggest that cisapride is a valuable drug in the management of gastro-oesophageal reflux disease in children.

Esophageal aperistalsis due to reflux esophagitis: a report of two cases.

Two small infants with gastroesophageal reflux disease and esophagitis are reported. Esophageal manometry revealed in both patients severe abnormalities consisting of aperistalsis and simultaneous low-amplitude motor waves. In one of the patients, defective relaxation of lower esophageal sphincter was also noted. Short-term intensive treatment with H2 antagonists resulted in symptomatic and endoscopic improvement as well as in manometric normalization. It is suggested that severe esophagitis may affect control mechanisms of esophageal motility, resulting in loss of coordination and decreased amplitude of contractions.

[Treatment of chronic functional constipation in children by administration of vegetable fiber (Dicoman 5)]. / Trattamento della stipsi cronica funzionale del bambino con somministrazione di fibre vegetali ("Dicoman 5").

Chronic functional constipation is a common clinical disorder in pediatric age. Thirteen children with functional constipation were treated by administration of vegetable fibres together with a toilet training program, for two months. In each patient anorectal manometry showed presence of inhibitory anal reflex and diagnosis of constipation was confirmed by a prolonged gastrointestinal transit time measured by radio-opaque markers. In all patients there was a significant improvement in both stool frequency and intestinal transit time; furthermore, a normalization of anorectal motility variables was observed at rectal manometry. No changes in the blood levels of nutritional parameters were seen in any patient. It is concluded that vegetable fibres represent an effective treatment of functional chronic constipation in children.
