We report a patient with Sjögren's syndrome and multiple gastrointestinal manifestations who successfully responded to therapy with ursodeoxycholic acid. Our patient had sialoadenitis with dry mouth, dry eyes, arthralgia, chronic pancreatitis, sclerosing cholangitis, and pulmonary inflitrations. The first signs of disease were the symptoms of chronic pancreatitis followed by icterus, caused by extrahepatic bile duct obstruction. Sclerosing cholangitis was diagnosed by liver biopsy and endoscopic retrograde cholangiography. Sialoadenitis, causing dry mouth, was verified by buccal biopsy. Pulmonary infiltrations were seen on standard chest x-ray, and also shown by high-resolution computed tomography examination. Obstructive icterus and even pulmonary infiltration responded successfully to treatment with ursodeoxycholic acid. 相似文献

The effectiveness of THA (an anticholinesterae) on scopolamine (0.4 mg/kg) and nucleus basalis (NB) lesion-induced change in neocortical spectral electroencephalography (EEG) were investigated. Scopolamine increased the amplitudes of all the spectral components in waking-immobility. In the movement-related EEG spectral values, only the alpha power was increased. THA 7.5 mg/kg, but not THA 3 mg/kg, could reverse scopolamine-induced amplitude change. NB lesioning increased delta and theta amplitudes, but decreased beta amplitude. Delta amplitude was increased during movement recordings in NB-lesioned rats. THA 7.5 mg/kg and pilocarpine 10 mg/kg, but not THA 3 mg/kg, could partially reverse the increase of delta and theta amplitudes induced by NB lesions. However, the beta power decrease could not be restored with cholinomimetics. This study demonstrates that quantitative EEG activity analysis may reflect the THA-induced restoration of the function of the cholinergic nucleus basalis. 相似文献

Vigabatrin (gamma-vinyl GABA; GVG) is a new antiepileptic drug (AED) that increases the level of the inhibitory transmitter, gamma-aminobutyric acid (GABA) in the brain. We evaluated the effect of GVG on the EEG of normal rats. GVG was administered intraperitoneally (i.p.) at a dose of 100 mg/kg once a day for 12 days. EEG was recorded at baseline, on the fourth day, at the end of the 12-day GVG period and 10 days after discontinuation of GVG. GVG increased the amplitude of delta (1-4 Hz) and theta (4-8 Hz) frequency bands and resulted in slowing of the peak frequency (Fp) and mean frequency (Fm) in both the frontal and occipital cortex, especially during waking-immobility. EEG changes normalized within 10 days after the last GVG injections. The results suggest that a relationship may exist between the EEG changes and increase in GABA levels with GVG. 相似文献

We have performed a two-stage study to analyse the association of polymorphism on chromosome 2q33 with multiple sclerosis (MS). In all, 17 markers were analysed in stage-1 in 134 Finnish MS families and the observed associations were tested in stage-2 in 186 MS families. We did not find previously reported allelic or haplotype associations with CTLA4. We obtained a weak signal of two distinct predisposing genes, one proximal the other distal of CTLA4. The putative proximal gene was associated with the marker rs3977 in families lacking HLA-DR2 (P=0.02 and 0.02) and the other distal gene was associated with D2S1271 in families from a high-risk region in western Finland (P=0.02 and 0.01). Based on the >3 cM distance and the lack of linkage disequilibrium between these loci, we conclude that the two association signals are independent. Our results provide preliminary evidence for two distinct MS susceptibility genes on 2q33 outside of CTLA4. 相似文献

In a Finnish kindred consisting of 192 descendants from two marriages of a male ancestor born in 1868, the lumbar spines of 105 of the 170 living members were X-rayed. Spondylolysis was found in 22 individuals. In addition, six of them had spondylolisthesis, four had spina bifida occulta, and two had a transitional lumbar/sacral vertebra. Seven members of the kindred without spondylolysis had spina bifida occulta and 10 had transitional lumbar vertebrae.
The pedigree is consistent with autosomal dominant inheritance and incomplete (about 75 %) penetrance for spondylolysis. It raises the question of a common aetiology for several congenital disturbances in the formation of lumbar vertebrae and possibly supports the concept of a variable expressivity of a "spondylolysis gene". 相似文献

Forty consecutive pregnant patients with insulin-dependent (Type I) diabetes mellitus were randomized at the end of the first trimester for treatment with conventional insulin therapy (CIT) or continuous subcutaneous insulin infusion therapy (CSII). Nine patients randomized into the CSII group declined the pump treatment. The mean glycosylated haemoglobin (Hb AIc) decreased (p less than 0.001) both in the CIT and the CSII groups with no difference between the groups. Some deterioration in retinopathy was found in 2/18 patients in the CIT group, in 5/13 in the CSII group, and in 3/9 of those who declined the pump treatment. The proportion of patients whose retinopathy progressed did not differ significantly between the groups, and in the majority the deterioration was mild. However, two patients in the CSII group developed acute ischaemic retinopathy, which progressed to proliferative stage in spite of laser treatment. In these two cases the decrease in the Hb AIc level was among the greatest and fastest in the study. These data suggest that a rapid near normalization of glycaemic control by CSII during pregnancy can accelerate the progress of retinopathy in poorly controlled diabetic patients. 相似文献

BACKGROUND AND AIMS: The aim of this retrospective study was to compare the relative costs of treating simple and spiral wedge (requiring closed reduction under anaesthesia) tibial shaft fractures in a plaster cast or with intramedullary locking nail. MATERIAL AND METHODS: The material consisted of 26 fractures treated in a plaster cast and 51 fractures treated with an intramedullary locking nail. The costs caused by the direct costs (treatment, hospitalisation, and outpatient appointments) as well as indirect costs (lost productivity) were taken into account. Costs caused by complications were also included in the analysis. RESULTS: Mean direct costs per patient were FIM 22920 and FIM 26952 and mean overall costs per patient were FIM 120486 and FIM 82224 in plaster cast and intramedullary locking nailing groups, respectively (FIM 1 = USD 0.19). The higher mean overall costs of the plaster cast group were attributable to the longer sick leave periods in this group (218 days in plaster cast group and 124 in intramedullary nailing group). CONCLUSION: Plaster cast treatment of simple and spiral wedge tibial shaft fractures requiring closed reduction under anaesthesia is more expensive to society than operative treatment with intramedullary locking nail. 相似文献

Detection of severe acute pancreatitis by contrast-enhanced magnetic resonance imaging 总被引:3,自引:0,他引:3

The aim of the study was to assess the ability of MRI to differentiate between the two forms of severity of acute pancreatitis
(AP), which is important for the detection of patients who require intensive monitoring and therapy. The second objective
was to evaluate whether the distinction would be possible regardless of the MRI equipment. Magnetic resonance imaging was
performed before and after intravenous administration of a gadolinium (Gd) chelate at 1.0 T using the breath-hold multislice
rapid gradient-echo turbo fast low-angle shot (FLASH) sequence in 14 patients, and at 1.5 T with the 2D FLASH(50) sequence
with fat saturation in 18 patients with acute pancreatitis early in the course of the disease. The patients were classified
according to the Atlanta classification system as having the mild (MAP) or severe (SAP) form of the disease. At 1.0 T with
use of a body coil, contrast-enhanced MRI failed to distinguish mild from severe pancreatitis. At 1.5 T with a phased-array
body coil, the signal intensities of the patients with SAP were statistically significantly lower than those of the MAP group.
Our initial clinical experience suggests that MRI with a sufficient magnetic field gradient strength may be useful for separating
the two forms of acute pancreatitis in their early phases.

OBJECTIVE: The aims of the study were to determine whether the caregivers of discharged patients with schizophrenia were satisfied with their situation in general and with psychiatric services in particular and to examine the factors associated with caregiver satisfaction. METHODS: The data were drawn from a national project designed to study the treatment and life situation of deinstitutionalized schizophrenia patients in Finland. The patients were discharged from psychiatric hospitals in 1986, and both the patients (N=775) and their caregivers (N=545) were interviewed after a three-year follow-up. RESULTS: One-fifth of the caregivers were dissatisfied with the situation in general, and one-third were dissatisfied with the psychiatric services the patient received. Caregivers were more likely to be dissatisfied with the situation if they lived with the patient and if the patient's functional state was poor or the patient's use of services, particularly medication and rehabilitation, was low. Caregivers were likely to be dissatisfied with the psychiatric services if the patient had severe psychotic symptoms and poor "maintenance of grip on life" or if the patient was given less psychiatric care and rehabilitation or used more social services. CONCLUSIONS: The satisfaction of caregivers of persons with mental illness appears to have two dimensions. First, caregivers need to be accepted and treated as active partners in the patients' care and rehabilitation. Second, the burden on the families of persons with mental illness can be alleviated with long-term rehabilitation and care to help patients gain as high a functional state as possible. 相似文献
