The objective of our psychopathological analyses is to shed light on the position of irritable mood (dysphoria) in psychiatric diagnostics and nosology. In today's most commonly applied classification systems, the ICD-10 and the DSM-IV, dysphoria is mentioned mostly in the context of diagnostic criteria of personality and affective disorders. Other authors have emphasized the importance of dysphoric states in organic psychoses and delusional disorders. Summarizing the various publications on the nosological position, dysphoria is a nosological nonspecific syndrome which may occur in the course of all psychiatric disorders and illnesses. According to the results of our psychopathological analyses, the pathogenesis of dysphoria has to be considered as a multidimensional circular process in which various mental, physical and social factors act as predisposing, triggering and disorder-maintaining factors. Stressors induced by particular experiences and perceptions and by impaired health may lead to a dysphoric state if adequate coping mechanisms are missing. Dysphoria itself usually leads to a deterioration in the mental and physical state of the patient, and shows a clear impact on the patient's social network. The reactions of people close to the patient combined with the impaired mental and physical conditions of the patient cause the circle to restart. As contemporary diagnostic entities do not refer to pathogenesis, classical categorical diagnostics cannot provide the basis for effective pathogenesis-oriented therapy. A change of paradigm in diagnostics from a categorical to a dimensional approach thus becomes necessary. Following a dimensional diagnostic approach based on a dynamic model of vulnerability, a precise differential diagnosis of the complex constellation of conditions and their interactions becomes necessary in order to develop effective treatment strategies. Disorder-maintaining factors determine the treatment of the acute symptomatology, whereas predisposing and triggering factors serve as the basis for the prophylactic treatment. 相似文献

The paper at hand presents an investigation of the tensile behavior of high-strength, strain-hardening cement-based composites (HS-SHCC), reinforced with a single layer of continuous, two-dimensional textile made of ultra-high molecular weight polyethylene (UHMWPE). Uniaxial tension tests were performed on the bare UHMWPE textiles, on plain HS-SHCC, and on the hybrid fiber-reinforced composites. The bond properties between the textile yarns and the surrounding composite were investigated in single-yarn pullout experiments. In order to assess the influence of bond strength between the yarn and HS-SHCC on the tensile behavior of the composites with hybrid fiber reinforcement, the textile samples were analyzed both with, and without, an additional coating of epoxy resin and sand. Compared to the composites reinforced with carbon yarns in previous studies by the authors, the high elongation capacity of the UHMWPE textile established the higher strain capacity of the hybrid fiber-reinforced composites, and showed superior energy absorption capacity up to failure. The UHMWPE textile limited the average crack width in comparison with that of plain HS-SHCC, but led to slightly larger crack widths when compared to equivalent composites reinforced with carbon textile, the reason for which was traced back to the lower Young’s modulus and the higher elongation capacity of the polymer textile. 相似文献

Behcet's disease is a chronic relapsing multisystem disorder of unknown etiology. Neurological complications are frequent, occurring in 10 to 49% of cases. We report 4 cases with Behcet's disease (3 females and 1 male) who had symptomatic intracranial hypertension due to cerebral venous sinus thrombosis within a mean delay of 2 years. The mean age at onset was 31 years and the mean age on referral was 39.5 years. The predominant manifestation in our series were headache, papilledema, seizures and pyramidal syndromes. CT Scan showed non specific abnormalities in all of them and the sinus venous thrombosis was confirmed by MRI in 3 cases. The authors emphasize on the importance of MRI with angio MRI for the diagnosis, the outcome and the evaluation of the cerebral venous thrombosis after treatment. 相似文献

The actinomycosis is a chronic suppurative granulomatosis disease. It is owed to a bacillus gram positive; actinomycès israelli. The cervical and thoracic localizations are most frequent. The digestive localization represents 20% of cases. It interest very rarely the pelvis and the genital tracts. We bring back the observation of a patient old of 30 years admitted for mass abdominal. To the exam, the patient had a sensibility of the left hypochondriac area and we found a mass of 6 cm of diameter. To the rectal touch, we found a mass in the bag of Douglas. The echography and the computed tomography revealed a collection under the spleen and a pelvic collection. A rectotomy is performed. The bacteriological study isolates actinomycès israelli. The collection under the spleen is drained under radiological control. Actinomycès israelli is also recovered in the pus brought back by the puncture. The patient is treated by Penicillin. The patient had a favourable evolution. No etiology is found at this patient. For this observation, the collection was accessible to a drainage permitting the diagnosis and the treatment of the actinomycosis while avoiding a mutilated surgery. 相似文献

OBJECTIVES: To evaluate the type and incidence of gastrointestinal manifestations secondary to scorpion envenomation and their prognostic significance. PATIENTS AND METHODS: All patients admitted to our ICU for scorpion envenomation were included in this retrospective chart review of a 13-year period (1990 - 2002). RESULTS: During the study period, 951 patients were admitted for scorpion envenomation and 72 (7.6%) died. Ages ranged from 0.5 to 90 years with a mean of 14.7 +/- 17.4 years. Gastrointestinal symptoms were present in 700 patients (73.6%): nausea in 24 (2.5%), vomiting in 687 (72.2%) and diarrhea in 41 patients (4.3%). At univariate analysis, the presence of diarrhea was associated with a fatal outcome (P < 0.05). Diarrhea was also correlated with other indicators of severe envenomation and poor prognosis: respiratory failure (P = 0.01), neurological failure (P < 0.0001), liver failure (P < 0.0001) and low blood pressure requiring catecholamine support (P = 0.02). The multivariate analysis showed that young age (age less than 5 years), fever > 38.5 degrees C, neurological failure and pulmonary edema were independent factors of severity. Digestive disorders were more frequent in children and in this subgroup diarrhea appeared to be associated with poor outcome. In a subset of patients for whom data were available, fatal cases demonstrated significantly higher liver enzymes levels on admission. CONCLUSION: In Tunisia, gastrointestinal symptoms are often observed in severe scorpion envenomations, especially in young patients. In children, diarrhea and elevated liver enzymes are associated with poor prognosis. 相似文献

BACKGROUND: This study aimed to determine predictive factors of mortality after posttraumatic brain injury. METHODS: A retrospective study conducted over a 3-year period (1997-1999) involved 437 adult patients with head injury admitted to the intensive care unit of a university hospital in Sfax, Tunisia. Basic demographic, clinical, biologic, and radiologic data were recorded at admission and during the intensive care unit stay. RESULTS: This study included 393 men (90%) and 44 women with a mean age of 36 +/- 17 years. Traffic accidents were the main cause of trauma (85.6%). In 58% of the cases, the injury was serious (Glasgow Coma Score, <8). The mean simplified acute physiology score was 39 +/- 15, and the mean Injury Severity Score was 34.5 +/- 17. Of the 437 patients, 127 (29.1%) died. According to multivariate analysis, the factors that correlated with a poor prognosis were age older than 40 years (p < 0.01), simplified acute physiology score exceeding 40 (p < 0.001), Glasgow Coma Score lower than 7 (p = 0.03), intracranial mass lesion (p = 0.02), a cerebral herniation (p < 0.001), diabetes insipidus (p < 0.001), and blood sugar level higher than 10 mmol/L (p < 0. 001). CONCLUSIONS: In Tunisia, head injury is a frequent cause of hospitalization, comprising 14.4% of all adult admissions. It is observed most often among young patients involved in traffic accidents. The short-term prognosis is poor, with a high (29%) mortality rate, and determined by demographic, clinical, radiologic, and biologic factors. Prevention is highly advised. 相似文献
