Rhabdomyolysis due to severe hypokaliemia in a Crohn's disease patient after budesonide treatment.

Patients with Crohn's disease may experience several non-digestive complications, including muscle disorders. Rabdomyolysis has rarely been reported in patients with inflammatory bowel disease, however a number of factors may cause muscular damage in this setting. We report the case of a young woman with Crohn's disease who developed a severe, symptomatic skeletal muscle damage associated with severe hypokaliemia. Reversal of the potassium levels to normal ranges led to clinical resolution. The possible causes that might have lead to hypokalemia development and subsequent rhabdomyolysis are discussed with special emphasis for the potential causative role of medical treatment, especially budesonide for which similar side effects have been previously reported. Physicians should be aware that hypokalemia is possible in the setting of Crohn's disease and muscle damage can present as a complication.

Evaluating a community-based mental health service focusing on severe mental illness. The Verona experience.

OBJECTIVE: To describe the development of a community-based mental health service, the patterns of care provided by this new service established in 1978 and its costs. METHOD: The South-Verona Psychiatric Case Register, the South-Verona Outcome Project and studies designed to assess costs provided process and outcome data. RESULTS: This paper summarizes descriptive statistics as well as the results of some evaluative studies conducted over the last 25 years in Verona, Italy. It reports patterns of care provided over the years by this new, comprehensive community-based service, targeted to the severely mentally ill but available also to all other residents in the area who need mental health care. CONCLUSION: Developing community-based mental health care requires a series of coordinated actions that need to be pursued over a long period of time. Service evaluation, including costs assessment, is an important part of this exercise.

Dose-finding study of weekly docetaxel, anthracyclines plus fluoropyrimidines as first-line treatment in advanced breast cancer.

BACKGROUND: The efficacy and safety of prolonged fluoropyrimidines, either intravenously or orally, prompted their integration with taxanes and anthracyclines in the treatment of advanced breast cancer (ABC). We conducted three subsequent dose-finding studies on first-line chemotherapy in ABC with anthracyclines, either epirubicin (E) or doxorubicin (A), and docetaxel (T), both given on days 1 and 8 every 3 weeks, plus continuous infusion (CI) 5-fluorouracil (F) or capecitabine (X). PATIENTS AND METHODS: Sixty-two patients (37% dominant visceral disease, 48% locally advanced disease, 45% two or more sites involved), received different doses of T (60--80 mg/m(2)), A (40--50 mg/m(2)) or E (60--90 mg/m(2)) and X (1,650 and 2,000 mg/m(2)), or CI F at a fixed daily dose of 200 mg/m(2). Cardiac function was monitored at baseline and then every four cycles by echocardiography. RESULTS: The median number of cycles per patient with all regimens was four (range one to eight). Haematological and gastrointestinal toxicity defined the maximum tolerated doses, at T-80/E-90 mg/m(2) with TEF, T-70/A50/X-2,000 mg/m(2) with TAX and T-70/E-80/X-1,650 mg/m(2) with TEX. Two patients treated with TEF developed transient cardiac toxicity (dilatative cardiomyopathy and coronary subtotal stenosis requiring stenting) after cumulative E doses of 400 mg and 1,100 mg/m(2), respectively. Fifty-nine patients were evaluable for response; the overall response rates (ORR) were comparable between regimens (54% with TEF, 71% with TAX and 86% with TEX), with an 81% ORR in 31 patients with locally advanced disease. CONCLUSIONS: The addition of fluoropyrimidines to weekly, intermittent ET is well tolerated and active in ABC.

Role of the "National Reference Centre for Genetically Modified Organisms (GMO) detection" in the official control of food and feed.

The National Reference Centre for Genetically Modified Organisms (GMO) detection was established in 2002 within the Istituto Zooprofilattico Sperimentale Lazio e Toscana, with the aim of providing scientific and technical support to the National Health System and to the Ministry of Health within the scope of the regulation of GMO use in food and feed.The recently adopted EU legislation on GMOs (Regulation CE no. 1829/2003 and no. 1830/2003) introduced more rigorous procedures for the authorisation, labelling and analytical control of food and feed consisting, containing or derived from GMOs. The National Reference Centre, besides its institutional tasks as one of the laboratories of the Italian National Health System, collects and analyses data and results of the national official control of GMOs; carries out scientific research aimed at developing, improving, validating and harmonising detection and quantification methods, in cooperation with other scientific institutions, the Community Reference Laboratory and within the European Network of GMOs laboratories (ENGL); collaborates with the Ministry of Health in the definition of control programmes and promotes educational and training initiatives. Objectives defined for 2004-2006, activities in progress and goals already achieved are presented.

Campylobacter jejuni enterocolitis presenting as inflammatory bowel disease.

We report a case of Campylobacter jejuni enterocolitis presenting as inflammatory bowel disease in a 19-year old woman. After a useless course of corticosteroids, ceftazidime and metronidazole, she was successfully treated with erythromicin. Campylobacter species represent an important cause of gastroenteritis in children and adults. The rate of Campylobacter isolation is 5-6 per 100,000 persons. This rate, however, grossly understimates the actual number of Campylobacter infections. In most cases, Campylobacter enteritis is a self-limiting disease, rarely associated with severe complications. Our case demonstrates the difficulty in distinguishing inflammatory bowel disease (Crohn's disease or ulcerative colitis) at onset from atypical infectious colitis. Unfortunately, corticosteroids (necessary for the treatment of inflammatory bowel disease) may exacerbate infectious etiologies. Campylobacter jejuni should be ruled out when assessing inflammatory bowel diseases at onset (as during flare-ups), especially if corticosteroids or immunosuppressive therapies are required.

Genetic variation atapolipoprotein E locus in Ethiopia: an E5 variant corresponds to two different mutant alleles: E*5 (Glu212Lys) and E*5 (Gln204Lys; Cys112Arg).

A previous investigation on apolipoprotein E polymorphism in the Ethiopian population highlighted the presence of a further variant allele named E*5 in addition to the three common alleles. The variant is considered rare elsewhere but has a frequency of more than 1% in this population. Now characterized by gene sequencing and restriction isotyping in many members of the families of the original carriers, the variant isoform has actually been found to be determined by two different gene mutations. Effectively rare in Ethiopians, one of the two, E5 (Gln204Lys, Cys 112Arg), has never been described before. The other, E5 (Glu212Lys), previously described in a subject of Turkish origin, is present at the polymorphic level only in the Ethiopian population. No subjects bearing these variants had anomalous lipid or apolipoprotein patterns. In the course of the present investigation both have been found to occur as rare variants in the southern Italian population as well. The occurrence of the two variants in the populations of Ethiopia and of the Mediterranean basin could be explained by taking into account the relevant Caucasoid contribution to the Ethiopian gene pool.

[Physiopathologic approach in esophageal motor disorders: from the diagnosis to therapeutic implications].

Motor disorders are an important chapter in esophageal pathology; from a clinical point of view, these disorders are characterised by dysphagia, non-cardiac chest pain, pyrosis and regurgitation. It is important to underline that chest pain and dysphagia are not specific to motility disorders; in fact, they are also present in other pathologies like peptic or infective esophagitis. In order to attribute these symptoms to a functional cause, it is first of all is necessary to exclude an organic pathology; this can be done with the help of radiological and endoscopical examination when the symptoms are dysphagia, pyrosis and regurgitation, or with electrocardiography or angiography, when the symptom is chest pain. The functional pathology is marines studied by manometric and pH-metric techniques. The manometric technique represents an important instrument for diagnosing esophageal motor disease. The aim of this study, after a review of the literature, is to describe the principal esophageal motor disorders and the physiopathological approach, that have important implications in diagnosis and therapy.

Determinants of subjective quality of life in patients attending community-based mental health services. The South-Verona Outcome Project 5.

OBJECTIVE: Investigate the relationship of various domains of quality of life (QoL) with socio-demographics, clinical and social characteristics, service use and satisfaction in a representative sample of patients in contact with the South-Verona community mental health service. METHOD: Measures included: Lancashire Quality of Life Profile (LQOLP), demographics, diagnosis and service utilization data from the Case Register, Brief Psychiatric Rating Scale (BPRS), Disability Assessment Schedule (DAS), Global Assessment of Functioning (GAF) and Verona Service Satisfaction Scale (VSSS). Analyses were conducted using a block-stratified multiple regression model. RESULTS: Demographics, diagnosis, psychopathology, disability, functioning and service use together explained different amounts of variance in each LQOLP domain, but always less than 14%. VSSS explained more variance than any other indicator in health (13.1%), social relations (12.1%), leisure/participation (9.1%), and general wellbeing (9.0%). CONCLUSION: Different domains of QoL are predicted by different indicators. In some important domains, self-perceived satisfactory and effective care might have an impact on the QoL of patients.

Quality of life in patients with schizophrenia in five European countries: the EPSILON study.

OBJECTIVE: To compare subjective quality of life (QOL) and objective QOL indicators in patients with schizophrenia from five European sites: Amsterdam, Copenhagen, London, Santander and Verona. METHOD: A representative sample of 404 patients with schizophrenia, in contact with mental health services, was randomly selected and evaluated with the Lancashire Quality of Life Profile (EU). RESULTS: The level of satisfaction in certain domains, religion, family and social relations appears to be associated with local style of living and culture while work, finances, and safety were more independent from local variations. In addition to the severity of symptoms, frequency of contacts with family, friendship and age appear as predictors of QOL, all of them influenced by the characteristics of the surroundings. CONCLUSION: The centres participating in the study presented differences in subjective measures of QOL, objective indicators and also in service provision and styles of living.

Congenital absence of the inferior vena cava: a rare risk factor for idiopathic deep-vein thrombosis.

Congenital absence of the inferior vena cava (AIVC) is a rare vascular defect, commonly reported as a fortuitous finding. The presence of AIVC in patients with DVT is underestimated because AIVC cannot be detected by compression B-mode ultrasonography. By use of computed tomography, we diagnosed four cases of AIVC in young patients with idiopathic DVT over a 5 year period. Based on the occurrence of DVT in patients below 30 years in our area during the same period, we estimate that AIVC is present in about 5% of cases of DVT in young patients. Computed tomography or angiography should be used for the diagnosis of idiopathic DVT in young patients.

Subjective and objective dimensions of quality of life in psychiatric patients: a factor analytical approach: The South Verona Outcome Project 4.

BACKGROUND: Both subjective and objective information is necessary to assess quality of life (QOL). AIMS: To explore the role of subjective and objective QOL dimensions and their cross-sectional and longitudinal predictors. METHOD: The relationship between QOL, as measured by the Lancashire Quality of Life Profile (LQL), and demographic variables, diagnosis, psychopathology, disability, functioning, affect balance, self-esteem, service use and service satisfaction was investigated at two points in time, using factor analysis and multiple regression techniques. RESULTS: One subjective and two objective LQL factors with strong face validity were identified. Cross-sectional predictors of the subjective factor were primarily subjective measures; longitudinally, few predictors of this factor were identified. The cross-sectional and longitudinal predictors of the objective factors were primarily demographic and observer-rated measures. CONCLUSIONS: Subjective and objective data are distinct types of information. Objective measures may be more suitable in detecting treatment effects. Subjective information is necessary to complete the QOL picture and to enhance the interpretation of objective data.

Polymorphisms in the apolipoprotein E gene regulatory region in relation to coronary heart disease and their effect on plasma apolipoprotein E.

In a previous study which examined the distribution of apolipoprotein E genotypes and plasma levels in a sample of male coronary heart disease (CHD) patients and controls, we found a significant excess of the genotypes carrying APOE*4 allele in CHD men (18.2%) vs. controls (9.6%) and an association between the APOE*4 allele and the lowest concentrations of apoE. In the present investigation, we re-examined in the same samples two recently identified polymorphisms in the promoter region of APOE, -491A/T and -427T/C, which may alter the level of apoE expression. No differences in the distributions of the -491A/T genotypes and alleles were observed between cases and controls (-491*A = 0.760 and 0.757 respectively). Polymorphism -427T/C showed in CHD patients an excess of -427*C allele (patients vs. controls = 0.123 vs. 0.074) and corresponding genotypes that was marginally significant. Stratification of the samples according to the presence/absence of APOE*4 showed that the excess of the -427*C allele concerned only CHD patients not carrying APOE*4 allele (patients vs. controls = 0.133 vs. 0.061; p=0.017). This result suggests that the presence of -427*C allele could represent a risk for developing CHD in subjects with E2/E2, E3/E2, and E3/E3 genotypes. Studies carried out on patients with Alzheimer's disease demonstrated that -491A/T and -427T/C polymorphisms affect the level of plasma apoE. In the present study, carried out on CHD patients and controls, the genetic variation at -427 and -491 sites of the APOE regulatory region had no apparent effect on apoE plasma concentration.

Phenotypic APC resistance in carriers of the A20210 prothrombin mutation is associated with an increased risk of venous thrombosis.

We hypothesized that increased prothrombin levels associated with G20210A prothrombin gene mutation could affect the results of activated protein C (APC) resistance phenotype and increase the risk of venous thrombosis (VT). The increasing addition of purified prothrombin in plasma of 90 normal subjects resulted in a parallel significant increase of APC resistance. Significantly different mean n-APC-SR in 879 GG20210 subjects compared to 27 heterozygous carriers of isolated G20210A mutation was observed (1.0 +/- 0.12 vs. 0.95 +/- 0.11; P = 0.02) in a random sample of 906 normal population subjects. Twenty-seven families with VT and isolated G20210A mutation consecutively diagnosed during 1998-1999 were evaluated. Mean n-APC-SR was significantly lower in the 80 G20210A carriers compared to 58 GG 20210 relatives investigated, even after sex and age adjustment (0.92 +/- 0.08 vs. 1.05 +/- 0.13; P < 0.0001). A strong relationship between plasma prothrombin level and n-APC-SR was observed in the families. When n-APC-SR values were grouped in tertiles, the odds ratio for VTE, after exclusion of the index cases and adjustment for 20210 status, for subjects in the lowest tertile (n-APC-SR 0.73-0.90) was 4.58 (95% CI 0.78-26.88) compared to upper tertile (n-APC-SR 1.01-1.30). In conclusion, in subjects with G20210A mutation APC resistance is significantly increased, correlates with plasma prothrombin level and the carriers with the lowest APC resistance values have an increased risk of VTE.

The perception of needs for care in staff and patients in community-based mental health services. The South-Verona Outcome Project 3.

OBJECTIVE: The present study aims to assess needs for care rated by patients and staff and their agreement on needs assessment in a community-based mental health service by using the Camberwell Assessment of Need (CAN). METHOD: The Italian version of the CAN was used in a sample of 247 patient-staff pairs. RESULTS: Patients and staff showed poor agreement on both the presence of a need and on whether need had been met or not. Higher disability predicted a higher number of patient-rated needs, while higher disability, higher number of service contacts and patient unemployment predicted a higher number of staff-rated needs. Lower global functioning predicted higher disagreement in patients and staff ratings of needs. CONCLUSION: Patients and staff show different perceptions of needs for care and therefore multiple perspectives should be taken into account for planning and providing effective needs-led mental health care.

Second malignancies in patients with essential thrombocythaemia treated with busulphan and hydroxyurea: long-term follow-up of a randomized clinical trial.

We have previously demonstrated that hydroxyurea (HU) reduces the rate of vascular complications in patients with essential thrombocythaemia (ET) at high risk of thrombosis. However, the relatively short follow-up (median 27 months) did not enable the evaluation of the risk of developing secondary malignancies. In this study, we report the long-term outcome of the 114 patients included in the trial: 56 patients randomized to receive HU and 58 patients to receive no cytoreductive therapy. Before randomization, 15 patients had been treated with busulphan. During the observation period, 29 patients (50%) shifted from the control to the HU group mainly because of thrombosis. Median follow-up was 73 months (range 3-94). Analysis was by intention to treat and, when indicated, by treatment. When analysed by intention to treat, 46 out of 54 patients (85%) originally randomized in the HU group are alive, compared with 49 of 58 patients (84%) in the control group [not significant (n.s.)]. Five patients (9%) in the HU group and 26 patients (45%) in the control group had thrombosis (P < 0.0001). Seven patients (13%) in the HU group developed secondary acute leukaemia, myelodysplastic syndromes or solid tumours, compared with only one of the control group patients (1.7%) (P = 0.032). The occurrence of secondary malignancies was also analysed by treatment: none of the 20 patients who had never been treated with chemotherapy developed neoplasia vs. three of the 77 patients given HU only (3.9% n.s.) and five of the 15 patients given busulphan plus HU (33% P < 0. 0001). This study showed that: (a) HU reduced the risk of thrombosis in ET patients; (b) the sequential use of busulphan and HU significantly increased the risk of second malignancies; and (c) overall survival was not affected by HU therapy.
