Fractures of tibial pilon are due to a high energy trauma. Associated skin complications are frequent as those of surgery
of this pattern. Thus we performed external fixation as treatment for these fractures. Authors report a retrospective study
of 17 closed fracture of tibial pilon, type C of Ruedi and Heim classification, treated by osteotaxis using external fixation
of Hoffman with osteosynthesis of fibula by screwed plate. Our patients are of a mean age of 34 years with 11 men and 6 women.
The right side was most frequently involved (12 patients). Skin injuries as phlyctena were seen in 6 patients. Delay of treatment
did not exceed 72 h. We performed a closed reduction of the fracture of tibial pilon after internal fixation of fibula by
screwed plate. Results were assessed after 24 months of study. Track pins infection was noted in three cases. Reduction was
usually good, despite one case of recurvatum, one case of valgus, one case of Sudeck’s atrophy, three cases of arthritis have
been noticed. Mobility decreased at about 30%. External fixation is a real alternative solution for treatment of these fractures
for which osteosynthesis is not suitable. It allows us to avoid skin complications despite mobility decreasing.

Background: Antinuclear antibodies (ANA) test is used to screen adults as well as children for connective tissue diseases (CTD) and autoimmune hepatitis. However, interpretation of ANA positivity can be delicate. Aim: to determine clinical significance and diagnosis utility of ANA positivity in children. Methods: Patients from a general pediatric department with ANA positive results were included (follow-up period of 2 years). ANA screening was performed by indirect immunofluorescence (IIF) on HEp-2 cells substrate (BioSystems®). In case of ANA positivity (cut-off: 1:80), the specificity was determined by IIF on Crithidia luciliea substrate (BioSystems®) and immunodot (Euroimmun®). Results: Among 102 ANA tests, 55 (53,9%) were positive. We recorded the data of 38 patients (age average: 9,5 years - sex ratio: 0.72). The most frequent signs were join pain (55,3%). ANA titer varied between 1:80 (39,5% of cases) and 1:1280 (2,6% of cases). Typing was negative in 89,5% of cases. The majority (42,1%) of children with positive ANA test had musculoskeletal diseases. The others (57,9%) had systemic lupus erythematosus(n=2), overlap syndrome(n=1), rheumatoid purpura(n=2), idiopathic thrombocytopenic purpura(n=1), coeliac disease(n=1) or non-autoimmune diseases/no confirmed diagnosis(n=15). Conclusions: ANA prevalence in children was relatively high. When the pretest probability is low, the positive predictive value for CTD or autoimmune hepatitis is low. However, depending on the clinical context, ANA detection can represent a supplement diagnostic tool for these diseases and/or can lead to a clinico-biological monitoring. 相似文献

The complexes: [CoL2](ClO4)2 (1), [FeL2](ClO4)2 (2), [NiL2](ClO4)2 (3) and [MnLCl2] (4), with L = diethyl-1,1′-(pyridine-2,6-diyl)bis(5-methyl-1H-pyrazole-3-carboxylate), were synthesized and fully characterized. Structural analysis revealed two distinct patterns influenced by the counter ions where L acts as a tridentate chelating ligand. The in vitro antitumor activity of L and L′ (diethyl 2,2′-(pyridine-2,6-diylbis(5-methyl-1H-pyrazole-3,1-diyl)) diacetate) as well as their metal complexes, was tested by the measurement of their cytostatic and cytotoxic properties towards the blood cancer mastocytoma cell line P815. We have also investigated their interactions with the antioxidant enzyme system. As a result, [MnL′Cl2] (1′) exhibited the strongest activity compared to reference cis-platin with no cytotoxicity towards normal cells PBMCs (Peripheral Blood Mononuclear Cells). On the other hand, the antioxidant enzyme activity showed that the efficiency of metal complex 1′ against P815 tumor cells was via the rise in the SOD activity and inhibition of CAT enzyme activity. This proof of concept study allows disclosure of a new class of molecules in cancer therapeutics.The complexes: [CoL2](ClO4)2 (1), [FeL2](ClO4)2 (2), [NiL2](ClO4)2 (3) and [MnLCl2] (4), with L = diethyl-1,1′-(pyridine-2,6-diyl)bis(5-methyl-1H-pyrazole-3-carboxylate), were synthesized and fully characterized. 相似文献

Shoulder-hand syndrome is a reflex sympathetic dystrophy which is usually associated with minor trauma, fracture or surgical procedures on bones, or follows peripheral nerve injury. In the present report, we describe a patient who developed sympathetic dystrophy which revealed a lung cancer. Reflex sympathetic dystrophy, therefore, should be considered an occasional manifestation of a paraneoplastic syndrome warranting a thorough search for underlying malignancy. 相似文献

Dermatomyositis and malignancy in Tunisia: a multicenter national retrospective study of 20 cases 总被引:5,自引:0,他引:5
Mebazâa A Boussen H Nouira R Rokbani L Ben Osman-Dhahri A Bouaouina N Laouani-Kechrid C Louzir B Zahaf A Kamoun MR 《Journal of the American Academy of Dermatology》2003,48(4):530-534
OBJECTIVE AND METHODS: The aim of our study was to report the epidemiologic, clinical, and biologic profiles of dermatomyositis (DM) associated with malignancy in patients from Tunisia. From January 1982 to January 2000, we collected retrospectively 20 case reports of DM associated with cancer from the different university hospital centers of Tunisia. Initial workup included anamnesis, clinical examination, cancer staging and classification, serum muscle enzymes (creatine phosphokinase, lactate dehydrogenase, aldolase, and transaminases), electromyography, and muscular biopsy. We calculated the median survival and mean value of all the variables. Comparisons of statistical tests were done with the Kruskal-Wallis test. RESULTS: Among the 130 DM cases of our study, 20 were associated with cancer (15.38%). The mean age of our patients was 49.6 years and the sex ratio (female/male) was equal to 3. Cancers were mainly those of the breast (35%) and nasopharynx (25%). DM followed a paraneoplastic course in 90% of the cases. The profile of seric muscular enzymes showed a significant statistical difference (P =.05) between a group of patients with severe muscular weakness and a group with moderate muscle weakness only for creatine kinase. The median survival was 36.5 months after diagnosis of DM and 48.6 months after that of cancer. The 5-year actuarial survival was 38% as related to cancer and 16% as related to DM. Mortality was 45%, in 90% as a result of cancer. CONCLUSIONS: In our study, nasopharyngeal carcinoma represents the second cancer associated with DM, after breast neoplasm, demonstrating the frequency of these 2 cancers in our country. Despite our reduced number of study samples, our study also suggests a relationship between severe muscle weakness and high seric muscle enzymes. 相似文献

The aim of this study is to specify the role of rapid tests in the screening of childhood urinary tract infection. During the period between july to december 1998, 572 urinary samples were collected from pediatric out-patient in H?pital d'Enfants de Tunis and aged from 1 month to 15 years. Only 75 samples (12.5%) were culture positive. The predictive value of leucocytes or nitrites test was 97.2%. These results allowed the use of rapid test in the screening of urinary tract infection in children. However, if clinical symptoms are present, the culture of urine must be associated to the rapid test. 相似文献
