Needs of caregivers of the patients with dementia.

This study was conducted to isolate the needs families express both for medical and psychological care, and for educational and social support in 112 caregivers of patients affected by moderate to severe dementia (mini mental state examination=MMSE score: 9+/-7) consecutively recruited at our Memory Clinic, to develop approaches as individualized as possible. The medical needs caregivers express are mainly relative to a better knowledge of the disease (78%) and the exact diagnosis (65%); the education-related needs are mainly relative to the acquisition of communicational skills (83%) and the optimal handling of cognitive (77%) and behavioral disorders (81%); the psychological ones mainly concern the area of assistance induced emotional stress management (37%) and the elaboration of feelings such as anxiety, rage and guilt (49%). Variance analysis shows a correlation between emotional caregivers' needs and the subjective and objective burdens they carry. Despite the attention to the role families play in caring for patients with a diagnoses of moderate to severe dementia, caregivers still express low levels of illness-consciousness and high levels of psychological discomfort. A lot more ought to be done in order to provide better information about the disease, about appropriate cognitive and behavioral disorder management skills, and about viable psychological support.

Fatigue in adult coeliac disease.

BACKGROUND: Fatigue is reported by many adults at the moment of diagnosis of coeliac disease and during follow-up. AIM: To evaluate the prevalence, characteristics and associations of fatigue in adult coeliac disease patients. METHODS: The investigated sample comprised adults from Campania, Italy. A total of 130 coeliac disease patients were consecutively recruited in both treated (59 on gluten-free diet) and untreated conditions (71 on normal diet). The control group was made up of 80 healthy controls. Coeliac disease patients and healthy controls underwent laboratory tests, a set of questionnaires for studying fatigue: visual analogue scale for fatigue, chronic fatigue syndrome questionnaire, fatigue severity scale and a modified version of the Zung self-rating depression scale. RESULTS: Coeliac disease patients showed a significantly lower body mass index than controls (P = 0.0001), lower serum iron (P = 0.04). The entire cohort of coeliac disease patients reported greater modified version of the Zung self-rating depression scale score (P = 0.001), greater visual analogue scale for fatigue score (P = 0.0001) and greater chronic fatigue syndrome questionnaire score (P = 0.0001) compared with healthy controls. Coeliac disease patients on a gluten-free diet had a significantly higher modified version of the Zung self-rating depression scale score than coeliacs on a normal diet (P = 0.001). The prevalence of pathological modified version of the Zung self-rating depression scale score was 17% in all coeliac disease patients and 0% in healthy controls. A significant correlation was found between modified version of the Zung self-rating depression scale score and fatigue scale scores in coeliacs on a normal diet. Presence/absence of gastrointestinal symptoms did not show any significant correlation with modified version of the Zung self-rating depression scale score and fatigue scale scores. In coeliacs on a gluten-free diet, modified version of the Zung self-rating depression scale and fatigue scales scores did not significantly differ from coeliacs on a normal diet and were not related to dietetic compliance. CONCLUSION: In coeliacs, fatigue is a common finding, which ameliorates with the gluten-free diet and is strictly correlated to depression although coeliacs on a gluten-free diet showed more frequent and more severe depression symptoms than coeliacs on a normal diet.

Substituted tetraazaacenaphthylenes as potent CRF1 receptor antagonists for the treatment of depression and anxiety.

Two isomers of the hexahydro-tetraazaacenaphthylene templates (1 and 2) are presented as novel, potent, and selective corticotropin releasing factor-1 (CRF1) receptor antagonists. In this paper, we report the affinity and SAR of a series of compounds, as well as pharmacokinetic characterization of a chosen set. The anxiolitic activity of a selected example (2ba) in the rat pup vocalization model is also presented.

Helicobacter pylori impairs iron absorption in infected individuals.

BACKGROUND: Infection with Helicobacter pylori is recognised as a major risk factor for chronic gastritis, peptic ulcer disease and gastric cancer. The association between H. pylori infection and iron deficiency anaemia has been established. Multiple mechanisms have been advocated to explain the relationship between H. pylori and iron status and their association might reduce iron deposit. AIM: Aim of this study was to investigate whether H. pylori infection affects iron absorption. METHODS: The study was designed on a prospective basis. Fifty-five subjects underwent upper gastrointestinal endoscopy and biopsy to investigate the presence of H. pylori and, when this was positive, also search of serum anti-CagA was performed. Tests included an oral iron absorption test with the administration of 1 mg/kg of Fe2+. Iron levels were measured before and 2 h after iron administration (delta iron). H. pylori-positive subjects were administered antibiotic therapy for 1 week and, 2 months later, the oral iron absorption test was repeated and urea-breath test was first performed. RESULTS: H. pylori-positive subjects had lower serum level of ferritin and lower delta iron compared to H. pylori-negative subjects. That difference is significant in anaemic women and is independent of the presence of serum anti-CagA antibodies. After H. pylori eradication iron absorption test was similar to those of non-infected subjects. CONCLUSION: H. pylori infection impairs iron uptake. That mechanism, together with others, may contribute to the depletion of iron in infected patients.

Abnormal esophageal acid exposure is common in morbidly obese patients and improves after a successful Lap-band system implantation.

BACKGROUND: The relation between gastro-esophageal reflux disease (GERD) and obesity is controversial. The laparoscopic adjustable gastric band (LAGB) procedure is effective for morbid obesity. Its indication in the presence of GERD, however, is still debated. This study aimed to investigate esophageal symptoms, motility patterns, and acid exposure in morbidly obese patients before and after LAGB placement. METHOD: For this study, 43 consecutive obese patients were investigated by a standardized symptoms questionnaire, stationary manometry and 24-h ambulatory pH-metry, and 16 patients with abnormal esophageal acid exposure were reevaluated 18 months after LAGB placement. RESULTS: Symptom scores and abnormal esophageal acid exposure were found to be significantly higher, Lower Esophageal Sphincter (LOS) pressure was significantly lower in obese patients than in control subjects. After LAGB, esophageal acid exposure was significantly reduced in all but two patients, who presented with proximal of gastric pouch dilation. CONCLUSIONS: There is a high prevalence of GERD in the obese population. Uncomplicated LAGB placement reduces the amount of acid in these patients with abnormal esophageal acid exposure.

Proximal stomach function in systemic sclerosis: relationship with autonomic nerve function.

Gastrointestinal involvement is frequent in patients with systemic sclerosis (SSc); however, studies on the proximal stomach and its regulation are lacking. It has been hypothesized that the primary event in the pathogenesis of gastrointestinal involvement in SSc is an early neural lesion. This study investigates proximal stomach function and its relation to autonomic nerve function in SSc. Twenty SSc patients classified in to clinical subsets, underwent measurement of proximal stomach function with and without glucagon by electronic barostat and an assessment of autonomic nerve function. SSc patients were not significantly different from 11 controls for gastric compliance (59.5+/-5.0 vs 47.7+/-4.2 ml/mm Hg, P = 0.1). The pressure-volume curves in each participant with and without glucagon were significantly different (P < 0.001). A significant positive association was found between gastric compliance and autonomic nerve function (P < 0.05). The change in gastric compliance during glucagon administration was significant-associated with autonomic function (P < 0.05). The perception cumulative scores did not differ between SSc patients and control subjects (P = 0.2). In conclusion, proximal stomach function is associated with autonomic nerve function in SSc patients. This confirms the frequent association of motility disorders with autonomic dysfunction in SSc.

Treatment of morbid obesity and gastroesophageal reflux with hiatal hernia by Lap-Band.

BACKGROUND: Esophageal reflux is common in obese patients. Hiatal hernia is considered a potential contraindication to placement of a Lap-Band. METHODS: Esophageal investigation in patients who were candidates for a Lap-Band included clinical evaluation of symptoms (scoring system), endoscopic and radiologic evaluation, 24-h pH test, and stationary manometry. Patients with gastroesophageal reflux (GER) with or without hiatal hernia underwent the Lap-Band procedure. RESULTS: GER was diagnosed in 12/40 morbidly obese patients, 11 of whom received a standard Lap-Band (3 patients were radiologically diagnosed with transient hiatal hernia). One patient with a large hiatal hernia underwent closure of the diaphragmatic esophageal hiatus, and the Lap-Band was positioned similarly to an Angelchik prosthesis. All but 1 patient who was lost at follow-up were symptom-free (range 1-24 months). CONCLUSION: GER with or without hiatal hernia is not a contraindication for obese patients undergoing a Lap-Band procedure. It accomplishes by a single operation satisfactory treatment of these two disturbing diseases.

Substituted analogues of GV150526 as potent glycine binding site antagonists in animal models of cerebral ischemia.

A series of analogues of the indole-2-carboxylate GV150526, currently in clinical trials as a potential neuroprotective agent for the control of the cerebral damage after stroke onset, was designed based on previous studies dealing with the electronic features of the north-east region of the glycine binding site associated with the NMDA receptor. In particular, the substitution of the para position of the terminal phenyl ring of GV150526 with suitable hydrophilic groups resulted in the identification of a new class of glycine antagonists. These compounds exhibited nanomolar in vitro affinity to the glycine binding site, high receptor selectivity, and outstanding in vivo potency. In particular, 3-[(E)-2-[(4-ureidomethylphenyl)aminocarbonyl]ethenyl]-4, 6-dichloroindole-2-carboxylic acid was found to be highly effective in the middle cerebral artery occlusion (MCAo) model in the rat, an animal model of focal ischemia, when given both prior to and after the occlusion of the middle cerebral artery. Notably, a significant neuroprotective effect was seen in this model postischaemia, when the administration of this compound was delayed up to 6 h from the occlusion of the middle cerebral artery, further confirming the wide therapeutic window seen for GV150526A.

Sexual behaviour in untreated and treated coeliac patients.

BACKGROUND: Sexual behaviour is often altered in chronic illness. AIM: To evaluate sexual behaviour in coeliac patients before and after treatment with a gluten-free diet. PATIENTS: Fifty-five adults with coeliac disease and 51 age- and sex-matched healthy controls. METHODS: Routine clinical and laboratory work-up was used for diagnosis of coeliac disease. Age of first sexual intercourse, prevalence of individuals who were sexually active, frequency of intercourse, reduction in sexual desire, difficulty in attaining orgasm, pain during intercourse, and prevalence of individuals defining themselves as satisfied with their sexual life were investigated by an anonymous, self-administered questionnaire administered before and after one year's treatment with a gluten-free diet in coeliac patients, and only once in controls. Analyses included clinical conditions, demographic and socio-economic data. RESULTS: Compared with controls, untreated coeliac patients had a significantly lower frequency of intercourse and a lower prevalence of individuals satisfied with their sexual life. Patients with overt and subclinical coeliac disease did not show significant differences for any indices of sexual behaviour. Compared with untreated conditions, coeliac patients after one year of treatment had improved values for all indices of sexual behaviour: differences were significant for frequency of intercourse and prevalence of individuals satisfied with their sexual life. CONCLUSION: Untreated coeliac disease, even in its subclinical presentation, is associated with disorders in sexual behaviour which are improved by the dietary treatment.

Esophageal impairment in adult celiac disease with steatorrhea.

OBJECTIVE: A high prevalence of reflux esophagitis in celiac children and gut motor disorders in adult patients have been described. The aim of this study is to investigate the prevalence of esophageal symptoms and the esophageal motility pattern in adult celiac patients before and after gluten-free diet. METHODS: In 22 consecutive adult celiac patients, before and after gluten-free diet, and in controls we calculated an esophageal symptom score regarding heartburn, regurgitation, dysphagia, and chest pain, and performed esophageal manometry using a constantly perfused multilumen catheter. RESULTS: Patients were divided into two groups: with and without steatorrhea. Before gluten-free diet, the prevalence of esophageal symptoms was 45.5 % in all patients, but was significantly higher in patients with steatorrhea than in those without and in 44 control subjects (80% vs 16.7% and 27%, p < 0.05). Lower esophageal sphincter pressure was 17.5+/-5.3 in all patients, but was significantly lower in patients with steatorrhea than in patients without steatorrhea and 11 controls subjects (13.1+/-4.1 vs 21.0+/-2.9 and 20.7+/-3.7 mm Hg (mean+/-SD, p < 0.05). After the diet, the prevalence of esophageal symptoms diminished in all patients (9% vs 45.4%, p < 0.05) and lower esophageal sphincter pressure, measured in 13 patients, increased (19.0+/-3.7 vs 15.7+/-5.3 mm Hg, p < 0.05). CONCLUSION: Adult celiac patients with steatorrhea present a higher prevalence of esophageal symptoms and a lowered lower esophageal sphincter pressure compared with celiac patients without steatorrhea and control subjects, but these phenomena can be reverted to control levels by gluten-free diet.

Small volume isosmotic polyethylene glycol electrolyte balanced solution (PMF-100) in treatment of chronic nonorganic constipation.

The present multicenter double-blind placebo-controlled trial evaluates the therapeutic effectiveness of small-volume daily doses of an isosmotic polyethylene glycol (PEG) electrolyte solution in the treatment of chronic nonorganic constipation. After a complete diagnostic investigation, patients still constipated at the end of a four-week placebo-treatment run-in period were enrolled and randomized to receive either placebo or PEG solution 250 ml twice a day for the following eight weeks. Patients were assessed at four and eight weeks of treatment, and they reported frequency and modality of evacuation, use of laxatives, and relevant symptoms daily on a diary card. Oroanal and segmental large-bowel transit times were assessed with radiopaque markers during the fourth week of the run-in period and the last week of the treatment period. During the study period, dietary fiber and liquids were standardized and laxatives were allowed only after five consecutive days without a bowel movement. Of the 55 patients enrolled, five dropped out, three because of adverse events and two for reasons unrelated to therapy; another two were excluded from the efficacy analysis because of protocol violation. Of the remaining 48 patients (37 women, age 42 +/- 15 years, mean +/- SD), 23 were assigned to placebo and 25 to PEG treatment. In comparison to placebo, PEG solution induced a statistically significant increase in weekly bowel frequency at four weeks and at the end of the study (PEG: 4.8 +/- 2.3 vs placebo: 2.8 +/- 1.6; P < 0.002) and a significant decrease in straining at defecation (P < 0.01), stool consistency (P < 0.02), and use of laxatives (P < 0.03). Oroanal, left colon, and rectal transit times were significantly shortened by PEG treatment. There was no difference between controls and PEG-treated patients as far as abdominal symptoms and side effects were concerned. In conclusion, PEG solution at 250 ml twice a day is effective in increasing bowel frequency, accelerating colorectal transit times, and improving difficult evacuation in patients with chronic nonorganic constipation and is devoid of significant side effects.

Celiac disease and pregnancy outcome.

OBJECTIVES: This study investigated the effect of gluten-free diet on pregnancy outcome and lactation in 125 women affected with celiac disease. METHODS: The study has been designed as a case-control study and a before-after study. RESULTS: In the case-control study, comparison of 94 untreated with 31 treated celiac women indicated that the relative risk of abortion was 8.90 times higher (95% confidence limits: 1.19/66.3), the relative risk of low birth weight baby was 5.84 times higher (90% confidence limits: 1.07/31.9), and duration of breast feeding was 2.54 times shorter (p < 0.001) in untreated mothers. Abortion, low birth weight of baby, and duration of breast feeding did not significantly relate to the severity of celiac disease among untreated women. In the before-after study, 12 pregnant celiac women in either treated or untreated condition were compared. Results indicated that the gluten-free diet reduced the relative risk of abortion by 9.18 times (95% confidence limits: 1.05/79.9), reduced the number of low birth weight babies from 29.4% down to zero (p < 0.05), and increased duration of breast feeding 2.38 times (p < 0.10). Both case-control and before-after studies indicated that threatened abortion and premature delivery did not significantly relate to treatment of celiac disease. CONCLUSIONS: The high incidence of abortion, of low birth weight babies, and of short breast-feeding periods is effectively corrected by gluten-free diet in women with celiac disease.

[Description of a case of Cotard's syndrome]. / Sindrome di Cotard. Descrizione di un caso.

The authors report the case of a male 61-year-old patient with Cotard's syndrome. Onset occurred three years ago with depressive symptoms that did not show the specific features of the syndrome, but failed to respond fully to treatment with tricyclic antidepressants. A probable later recurrence was characterised by elements typical of Cotard's syndrome. Treatment with tricyclic and serotoninergic antidepressants was ineffective. Encephalic NMR showed multiple ischemic foci and signs of cortical atrophy. Three years after the onset of depressive symptoms Cotard's syndrome is virtually unchanged and shows ingravescent mental deterioration.

[Sexual dysfunction in men and epilepsy]. / Disfunzioni sessuali maschili ed epilessia.

Sexual dysfunctions may represent a symptomatological aspect of epilepsy or it may be a consequence of the pharmacological therapy. This kind of trouble is frequently associated to primary generalized epilepsy and focal secondary epilepsy. In our investigation we considered a group of 30 males during treatment with drugs like phenobarbital, carbamazepine and valproate, at the "Center for the Study and the Treatment of Epilepsy", University of Turin, using a sexological and psychosomatic questionnaire. The purpose was the analysis of the sexuality in relation to a specific kind of epilepsy or to a particular drug.

Gender and clinical presentation in adult celiac disease.

BACKGROUND: Celiac disease may present in various forms. This study aimed to investigate whether gender affects the clinical presentation of the disease in adult celiac patients from the Mediterranean area. METHODS: This study retrospectively analyzes data collected in all adult patients with celiac disease (n = 195) seen during the past 13 years at the Gastrointestinal Unit of the Federico II University of Naples, Italy. RESULTS: In these series of patients the ratio of women to men was 3.33. Age at diagnosis was lower in women that in men (p < 0.05). Except for asthenia, all signs and symptoms were more frequent in women than in men. Hypochromic anemia was the most commonest finding in women and was 40% more frequent in women than in men (p < 0.001). Dyspepsia was twice as frequent in women as in men (p < 0.05); genital disorders were reported by 44% of women and by no men. Recent weight loss or low body mass index was the commonest finding in men. About 60% of men and women reported diarrhea; among patients without diarrhea, the prevalence of hypochromic anemia differed between sexes (p < 0.05), occurring in about 80% of women. CONCLUSION: This study shows that the clinical presentation of celiac disease is not the same in men and women. The disease is not only more frequent in women than in men but is also more severe and more rapid. The data also suggest the need to look for celiac disease in patients with unexplained hypochromic anemia.

Long term treatment with omeprazole 20 mg three days a week or 10 mg daily in the prevention of duodenal ulcer relapse.

BACKGROUND: The aim of this study was to compare omeprazole 10 mg o.m. (daily) with omeprazole 20 mg o.m. on Friday to Sunday inclusive (weekend) in the prevention of duodenal ulcer relapse over a 6-month period. METHODS: After an open healing phase (4 to 8 weeks) with omeprazole 20 mg o.m., 81 patients entered the follow-up phase. Forty-two were randomized in a double-blind double-dummy technique, to omeprazole 10 mg o.m., and 39 to omeprazole 20 mg at weekends. At 3 and 6 months or on symptomatic relapse the patients underwent endoscopy with gastric biopsies (quantitative assessment of argyrophilic and gastrin cells), symptom evaluation, and laboratory screening with fasting serum gastrin. RESULTS: Five patients in the 10 mg group and four in the weekend group were lost to follow-up. The estimated relapse rates over six months in the two groups receiving 10 mg daily or 20 mg at weekends were 19% and 31%, respectively (95% CI of percentage difference: -33% to 8%: intention-to-treat analysis, P = N.S.). During the follow-up phase, symptoms tended to be milder in the omeprazole 10 mg daily group compared to the weekend group. Gastrin levels increased significantly during the healing phase but then stayed almost constant in the omeprazole 10 mg group, and significantly decreased with weekend treatment. The median number of argyrophilic cells showed a slight but statistically significant increase in the omeprazole 10 mg daily group, but did not change in the weekend group. Both the healing and long-term therapies were well tolerated. CONCLUSIONS: Our data do not show a clear difference between the two treatment regimens, but there was a tendency towards a lower recurrence rate with omeprazole 10 mg daily compared with 20 mg weekend therapy.

[Esaprazole vs sulglicotide in the treatment of dyspeptic patients with chronic superficial gastritis of the antrum]. / Esaprazolo vs sulglicotide nel trattamento di pazienti dispeptici portatori di gastrite cronica superficiale dell'antro.

Fifty dyspeptic patients with histologically proven chronic superficial antral gastritis were treated for 6 weeks, in a randomized single-blind study, with esaprazole (450 mg bid) or sulglicotide (200 mg tid). Both drugs significantly improved the symptomatic score after 3 and 6 weeks (p less than 0.01), and the percentual rate of improvement was similar in the two groups studied. Similarly, both treatments significantly reduced the inflammation of gastric mucosa. Drugs were ineffective in clearing Helicobacter pylori from the antral mucosa (as assessed by the urease test, performed at entry and after 6 weeks). No side effects occurred after esaprazole or sulglicotide administration. The results of the present study suggest that esaprazole, a new gastroprotective drug, may have a role in the therapy of dyspeptic patients with chronic superficial gastritis.

Clinical efficacy and safety of cisapride and clebopride in the management of chronic functional dyspepsia: a double-blind, randomized study.

The clinical efficacy and the safety of chronic oral administration of cisapride, a new gastrointestinal prokinetic agent, (10 mg tid) and clebopride (0.5 mg tid) was assayed in 48 outpatients affected with functional dyspepsia, in a randomized double-blind study. Each of the drugs induced a significant reduction in dyspeptic symptoms after 2 and 4 weeks (p less than 0.001). Two patients, given clebopride, dropped out of the study because of severe side effects during the first week of treatment. Mild adverse reactions were reported in 6 out of 23 cisapride-treated patients and in 10 out of 20 clebopride-treated patients who completed the study. The most common side effect of cisapride was diarrhoea and that of clebopride was drowsiness. Cisapride appears to be as effective as clebopride in reducing dyspeptic symptoms and seems to induce less severe side effects.
