Systemic complications of esophageal lichen planus.

Lichen planus is an uncommon inflammatory mucocutaneous disorder affecting the skin and its appendages, as well as oral and genital mucosa. Involvement of the esophageal mucosa is rare and causes significant morbidity, with dysphagia and risk of long-term complications, such as esophageal strictures and stenosis. Esophageal lichen planus is an underreported condition in the spectrum of lichenoid tissue reactions, presenting the risk of systemic manifestations. We describe a patient with severe, long-standing esophageal lichen planus, which had led to marked weight-loss, malnutrition syndrome and chronic respiratory distress due to recurrent aspiration pneumonia. Diagnosis was confirmed by the presence of concomitant muco-cutaneous lesions and characteristic endoscopic and histological findings. Systemic therapy with cyclosporine A and micronutrient supplementation led to rapid clinical improvement. Early diagnosis of esophageal lichen planus as well as effective systemic immunosuppressive treatment is crucial in order to prevent short- and long-term complications.

Giant cell arteritis and polymyalgia rheumatica after influenza vaccination: report of 10 cases and review of the literature.

Giant cell arteritis (GCA) and polymyalgia rheumatica (PMR) are inflammatory rheumatic diseases common in people over the age of 50 years. Herein, we report 10 cases of previously healthy subjects who developed GCA/PMR within 3 months of influenza vaccination (Inf-V). A Medline search uncovered additional 11 isolated cases of GCA/PMR occurring after Inf-V. We discuss the role of individual susceptibility, the potential function of immune adjuvants as triggers of autoimmunity post-vaccination, and the correlation of our observation with the 'ASIA' syndrome, i.e. autoimmune/inflammatory syndrome induced by adjuvants and including post-vaccination phenomena.

Seroprevalence of Helicobacter pylori in children with type 1 diabetes mellitus in Sardinia.

A few studies have reported an increased prevalence of Helicobacterpylori (HP) infection in diabetic subjects, which may be one of the causes of gastrointestinal symptoms and chronic atrophic gastritis frequently seen in diabetes of long duration. We determined the prevalence of HP infection in children and adolescents with Type 1 diabetes mellitus (T1DM) in the area of Sassari (northern Sardinia, Italy), which is characterized by an ethnically homogenous population at high risk of T1DM. HP IgG and IgA titres were measured in 138 patients with T1DM and 138 age-matched healthy controls. The percentage of infected subjects did not differ between T1DM patients (29.7%) and controls (32.6%). Globally, infected subjects were more than 1 yr older (13.0 +/- 2.7 yr) than non-infected ones (11.8 +/- 2.9 yr), independently of the presence of T1DM; in most HP-positive subjects infection was asymptomatic, and only 2 subjects in each group reported clinically relevant symptoms. HP-positive and HP-negative diabetic patients had the same duration of the disease (5.6 +/- 3.5 vs 5.5 +/- 3.6 yr) and received very similar doses of insulin (0.94 +/- 0.27 vs 0.96 +/- 0.4 IU/kg/d), whereas mean HbA1c was significantly lower in HP-positive patients (7.8 +/- 1.6% vs 8.6 +/- 1.7%,p=0.02). We conclude that the prevalence of HP infection is not higher in Sardinian children with T1DM as compared to controls of similar age, and the overall clinical impact of HP infection in terms of gastrointestinal symptoms and diabetic control seems to be low.

High prevalence of lactose absorbers in Northern Sardinian patients with type 1 and type 2 diabetes mellitus.

BACKGROUND: Increased intestinal lactase activity has been shown to occur in alloxan and streptozotocin diabetic rats. OBJECTIVE: The objective of this study was to determine whether increased intestinal lactase activity is present in humans with diabetes mellitus. DESIGN: We assessed the capacity to digest lactose by measuring breath-hydrogen production after oral administration of lactose in 50 patients with type 1 diabetes, 50 patients with type 2 diabetes, and 50 healthy control subjects from Sassari, Sardinia, Italy, a population characterized by a low prevalence of lactase persistence (lactose absorbers). RESULTS: Fourteen percent of control subjects were lactose absorbers, compared with 48% of patients with type 1 diabetes and 52% of patients with type 2 diabetes (P < 0.005). The odds ratio of lactase persistence in patients with type 1 diabetes was 5.3 (95% CI: 2.0, 14.0) and in patients with type 2 diabetes was 5.5 (95% CI: 2.1, 14.5). CONCLUSIONS: Diabetes is associated with increased intestinal lactase activity in humans. Consequently, there is a greater exposure to glucose and galactose in diabetic patients with high lactose consumption. This may explain the association between diabetes and the risk of cataract.

[The Studer orthotopic ileal neobladder: patient compliance]. / Neovesciche ileali ortotopiche sec. Studer: "compliance" del paziente.

Radical cystectomy represents the gold standard for locally advanced bladder cancer. Orthotopic neobladder is considered the surgical option which may offer the least modification of body image and the best life condition to the unfortunate patient requiring radical cystectomy. Objective of this study was to investigate long term clinical outcome of orthotopic ileal bladder substitute with special reference to late complications and patient compliance. Twenty male patients 48 to 71 years old (mean age 59.8 + 7.4 years) underwent radical cystectomy and Studer orthotopic ileal neobladder for invasive carcinoma of the bladder. Before surgery all patients filled in a phycometric test for evaluating their knowledge capacity; after surgery they underwent a course of biofeedback and instructed to avoid overfilling of the neobladder with timed micturitions and a regular regimen of fluid intake. Pressure flow study was included in the routine follow-up carried out at six months and then yearly. Seventeen patients (85%), with a good knowledge capacity, reported a good compliance to the modified life style imposed by the bladder substitute, they all were dry during the day with 3 to 5.5 hour interval between micturitions; fourteen of these patients were continent at night with timed micturitions every 3-4 hours (mean: 3.2); an average cystometric capacity of 450 ml was found in these patients with no residual urine; three patients (18%) had incontinence episodes once or twice a week during the night; no decompensation of the neobladder, significant ureteral reflux or dilatation were reported; elongation of the afferent loop was found in one patient following small bowel resection for ileal volvulus. Three patients (15%), with a reduced knowledge capacity, who did not follow the suggested life style: fluid intake was irregular, micturitions were not timed during both day and night time, had residual urine larger than 400 ml. and incontinence episodes requiring pads; nevertheless no dilation of the upper urinary tract was found. Our experience suggests that careful compliance of patients to the new life style imposed by the orthotopic neobladder is of importance to avoid its decompensation. The possible causative role of gastrointestinal hormones such as enteroglucagon (EG) and peptide tyrosine-tyrosine (PYY) in the elongation of the afferent limb of the Studer neobladder is proposed. In conclusion, we believe that orthotopic ileal neobladder is an ideal surgical option on in the young, educated and cooperative patients.

IDDM and early infant feeding. Sardinian case-control study.

OBJECTIVE: To further investigate the association between the type of feeding in infancy and the development of IDDM. RESEARCH DESIGN AND METHODS: We have carried out a case-control study in the area of Sassari (northern Sardinia, Italy), which is characterized by an ethnically homogenous population at high risk of IDDM. The study subjects comprised 100 IDDM patients and 100 control subjects, matched for sex and age and selected from children admitted at the Department of Pediatrics of the University of Sassari. Diabetic children (53 boys, 47 girls) had been diagnosed between 1983 and 1994, and their age at diagnosis ranged between 1 and 15 years. Information on feeding patterns during the 1st year of life was collected through questionnaires administered to the mothers. The questionnaire was designed to evaluate the duration of complete or partial breast-feeding and the age at which dietary products containing cow's milk were introduced into the diet. RESULTS: A larger proportion of the diabetic children rather than the control children had been breast-fed, and the risk of IDDM among children who had not been breast-fed was below unity (odds ratio [OR] 0.41; 95% CI 0.19-0.91). No clear difference was observed between diabetic and control subjects in the duration of breast-feeding (medians: 3 and 2 months, respectively), even if, overall, the data suggested a slight increase in the risk of IDDM with longer duration of breast-feeding (OR 1.10; 95% CI 0.99-1.22 per month). Although a larger proportion of control children rather than diabetic children had been given cow's milk-derived formula and solid food before the age of 3 months, there was no time-risk relationship. CONCLUSIONS: Our data do not support the existence of a protective effect of breast-feeding on the risk of IDDM, nor do the data indicate that early exposure to cow's milk and dairy products has any influence on the development of IDDM in a high-risk population.

Accidental exposure to daily long-acting gonadotrophin-releasing hormone analogue administration and pregnancy in an in-vitro fertilization cycle.

A case of successful pregnancy in an in-vitro fertilization cycle, in spite of an accidental exposure to daily long-acting gonadotrophin-releasing hormone analogue administration, is reported. The patient underwent two intracytoplasmic sperm injection cycles with thawed epididymal spermatozoa, in which, due to a pharmacist's mistake, ovarian stimulation was carried out by a combination of long-acting gonadotrophin-releasing hormone agonist (leuprolide depot) and gonadotrophins. A successful singleton pregnancy was achieved after intrauterine embryo transfer with the birth of a healthy boy after 38 weeks. We describe the circumstances and results of this clinical case, as well as reviewing the literature.
