[Pyogenic psoas abscess: six cases and review of the literature].

PURPOSE: Psoas abscess is a rare disease in developed countries. Its diagnosis is difficult and any delay could lead to a worsen prognosis. The aim of this study is to determine the best diagnostic and therapeutic practices. METHODS: A retrospective study of psoas abscess that occurred during six months was performed. RESULTS: Six cases of secondary psoas abscess are reported. They were associated with spondylodiscitis in three cases, arthritis and gynaecologic infection in the three remaining cases. Anatomic diagnosis was performed by tomodensitometry. Microbiologic diagnosis was obtained by blood culture or direct puncture of the abscess. Antibiotics were associated with percutaneous drainage in two cases, with simple puncture in one case, and with surgery in one case. A local improvement w observed in all cases. The oldest patients presented the worst complications which were not directly caused by the abscess. CONCLUSION: Physicians must be aware of psoas abscess because of their increasing incidence. Despite the fact that digestive pathologies are the main cause of secondary psoas abscess, bone infections, particularly spine infections, should be taken into consideration. Tomodensitometry guided puncture or percutaneous drainage are of diagnostic and therapeutic interest. Infectious samples must be taken before starting antibiotics, which have to be efficient against Gram negative bacillus, anaerobes and Staphylococcus aureus. Surgery must be quickly performed when the primary infection localisation need it, in case of voluminous abscess or when antibiotics and drainage are inefficient.

[Acute nonalcoholic nonbiliary pancreatitis. Difficulties in diagnosis and possibility of nicotine toxicity].

INTRODUCTION: The possibility of nicotine toxicity, although rare, should be considered in cases of acute edematous pancreatitis. CASE: A 30-year-old woman was hospitalized to identify the cause of an initial episode of acute edematous pancreatitis. The observation of native anti-DNA and antiphospholipid antibodies suggested lupus pancreatitis and/or an antiphospholipid syndrome, both subsequently ruled out. The final diagnosis was nicotine poisoning induced by the combination of a nicotine patch and tobacco smoking. CONCLUSION: Although a nicotine patch has never been reported in connection with an episode of acute pancreatitis before, this case suggests that such an event might be a rare complication of an overdose of nicotine.

[Elevation of serum lactate dehydrogenase. Diagnostic, prognostic and evolutive values].

OBJECTIVE: Determination of serum lactate dehydrogenase (LDH) levels is an usual practice. However, its place in the diagnosis process is not clear. We have collected serum LDH levels superior to 2-fold the normal rate and we tried to determine their diagnostics interest and, predictive and progressive values. METHODS: Retrospective study during 3 months in hospitalized adults. LDH levels were measured by spectrophotometry (Normal rate: 313-618 UI/L). RESULTS: 196 cases with LDH level elevations higher than 1236 UI/L were analyzed. The etiology of LDH level elevations were was benign in 60% of cases, malignant in 36% and, undetermined in 5%. There was no difference in between average values of LDH level average values of benign and malignant etiology (2708 vs 2842 UI/l). LDH rates and high LDH level elevations were not helpful for in the diagnosis process (a variety of 43 etiology was able to elevate increased LDH rates). In 45% cases, LDH level was 2 to 3-fold the normal rate; in 47.5% cases, 3 to 10-fold normal rate, and in 7.5% cases, superior to 10-fold normal rate. LDH elevations superior to 10-fold the normal rate were caused by benign etiology in 11 cases and malignant disease in 4 cases. A level superior to 10-fold the normal rate was not helpful in determining to determine the benign or malignant characteristics of the initial disease. However, LDH rate superior to 10 normal rate was a pejorative predictive criteria (hospitalization in intensive careunity in 73% of cases and mortality rate of 53%). During follow up of a neoplasia or malignant hemopathy follow up, several LDH measurements LDH level determinations were determined in for a small number of patients. LDH level normalizations is are attributable to efficientan effective treatment; LDH level elevations are associated with a therapeutic failure echappment. Evolution in LDH levels evolution was influenced by progression in neoplasia and malignant hemopathy evolution and also by various several treatments such as like blood transfusions, growth factors, radiotherapy and chemotherapy. CONCLUSION: LDH level elevation, however whatever its rate, don't seem to do not help in differentiating have interest to differentiate benign from malignant diseases. However, an elevation LDH elevation higher than 10-fold the normal rate is a pejorative predictive criteria, since because the mortality rate is superior toupper than 50%. During follow-up of in the neoplasia and malignant hemopathy follow up, so long as they are measured at distance from treatment, variations in LDH levels are a good marker of evolution, rate variations represent an evolutive marker conditionally the level determination would be realize remote several treatment.

Mazabraud syndrome in two patients: clinical overlap with McCune-Albright syndrome.

Mazabraud syndrome is a rare sporadic disorder, mainly characterized by bone fibrous dysplasia and intramuscular myxomas. We report here two new cases of Mazabraud syndrome. One of our patients (Patient 1) also had café-au-lait spots and multinodular goiter suggestive of McCune-Albright syndrome. We review the 37 previously reported cases with Mazabraud syndrome and discuss the 6/37 patients with criteria of Mazabraud and McCune-Albright syndromes. Based on the clinical overlap between the two syndromes, we tested the GNAS1 gene in blood leukocytes and skin fibroblasts of Patient 1, but found no evidence of an activating mutation in the GNAS1 gene.

[Early signs of systemic disease in patients taking minocycline chlorhydrate].

BACKGROUND: Search for etiology in young subjects with joint disease must take into consideration causes other than reactional arthropathy or systemic disease. CASE REPORTS: Two young subjects consulted for joint pain involving various joints. Physical examination did not reveal any other abnormality. Serum tests were positive for antinuclear antibodies and/or showed moderately and persistently elevated transaminases. History taking revealed that these subjects had been taking minocyclin chlorhydrate for several months, or even years, for acne. Joint pain subsided with drug withdrawal and serum tests returned to normal. DISCUSSION: Long-term treatment with minocylin chlorhydrate should always be included in the search for an etiology in patients presenting joint pain.

Rheumatic disorders developed after hepatitis B vaccination.

OBJECTIVE: To obtain an overview of rheumatic disorders occurring after hepatitis B vaccination. METHODS: A questionnaire was sent to rheumatology departments in nine French hospitals. Criteria for entry were rheumatic complaints of 1 week's duration or more, occurrence during the 2 months following hepatitis B vaccination, no previously diagnosed rheumatic disease and no other explanation for the complaints. RESULTS: Twenty-two patients were included. The observed disorders were as follows: rheumatoid arthritis for six patients; exacerbation of a previously non-diagnosed systemic lupus erythematosus for two; post-vaccinal arthritis for five; polyarthralgia-myalgia for four; suspected or biopsy-proved vasculitis for three; miscellaneous for two. CONCLUSIONS: Hepatitis B vaccine might be followed by various rheumatic conditions and might trigger the onset of underlying inflammatory or autoimmune rheumatic diseases. However, a causal relationship between hepatitis B vaccination and the observed rheumatic manifestations cannot be easily established. Further epidemiological studies are needed to establish whether hepatitis B vaccination is associated or not with an incidence of rheumatic disorders higher than normal.

[Eosinophilic ascites and urticaria].

INTRODUCTION: The finding of eosinophilic ascites is unusual. It requires the search for the main etiology, i.e., parasitic or malignant disease, vasculitis or hypereosinophilic syndrome. The diagnosis of exclusion is either mucosal, muscular or serous eosinophilic gastroenteritis. This last type, the most unusual--as less than 50 cases have been documented until now--is associated with eosinophilic ascites. EXEGESIS: We report a new case of serous eosinophilic gastroenteritis that occurred in a 23-year-old woman. This case was unusual because of its clinical history, as abdominal pain fits (along with the occurrence of ascites) were associated with urticaria fits. The lack of eosinophils in both the blood counts and the various digestive biopsies were unusual too. The disease evolution was favorable with corticosteroid therapy; however, a minimal dose of 8 mg/day was necessary to control the disease symptoms. CONCLUSION: Because of its association with urticaria fits, this case emphasizes the need for differential diagnosis in patients with hypereosinophilic syndrome and food allergy.
