[The Munchausen syndrome: a diagnosis not to be forgotten in urology].

INTRODUCTION: Among the manifestations of Münchausen's syndrome, "neurological" forms may exist. OBSERVATION: We present the case of a patient presenting with urinary retention following treatment for urinary incontinence. The patient had injected himself with infected urine collected from his catheter, in order to create septicemia. COMMENTS: Nephritic colitis, false gall stones, addition of fecal matter or of food and saliva in the urine or the bladder, neurogenic bladder and urinary infections have all been reported as possible manifestations of Münchausen's syndrome. Diagnosis of this syndrome is often delayed and laborious, after repeated hospitalisations, examinations and often aggressive treatment. Its therapeutic management is difficult. Patients, despite proof, deny their deceit and refuse psychiatric care.

Acute selenium poisoning.

Reports of acute human selenium toxicity are rare. We report 2 new cases. One patient ingested a mouthful of selenic acid (30 g/L); he only suffered mild gastrointestinal disturbances. Serial measurements of plasma selenium concentrations were performed. The first plasma level was obtained 3 h after ingestion and was the highest (931 micrograms/L); plasma concentrations subsequently decreased with a half-life of 17.5 h. The second patient ingested 1.7 g of sodium selenite. He suffered severe gastroenteritis, had transient electrocardiographic changes and developed a slight elevation of serum bilirubin. The first serum concentration measurement was performed 3 h after ingestion; the selenium level was 2.716 micrograms/L. These data are compared to those from other published cases. The prognostic significance of the blood selenium concentration is discussed.

[Contribution of gradient-echo MRI in the study of subacromial pathology: correlation between surgery and arthrography].

30 asymptomatic volunteer subjects and more than 400 patients with suspected rotator cuff lesions were examined by MRI at 0.5 T using T2*-PD weighted gradient echo (T2-GEI) sequences. Its superiority over T2 spin echo imaging was established in previous studies. The results were compared to those of surgery in 87 cases and arthrography in 233 cases (associated with CT arthrography in 70 cases). In the operated patients, T2-GEI and arthrography correctly diagnosed 49 complete ruptures (CR). T2-GEI was found to be superior to arthrography for defining the real extent of the rupture, the degree of tendon retraction and the local muscular trophicity, essential information to define the therapeutic indications. In contrast, among 22 lesions of the long biceps tendon, correctly demonstrated by arthrography or CT arthrography, 5 intracapsular lesions were not detected by MRI. MRI was able to detect 8 lesions of the anterior labrum associated with a CR not demonstrated by arthrography. Lastly, among the 18 cases of partial inferior rupture (PIR), 6 partial superficial ruptures and 14 cases of inflammatory changes, correctly diagnosed by MRI, only 8 PIR were also demonstrated by arthrography. For the non-operated patients investigated by the two modalities (146 cases), T2-GEI and arthrography were concordant in 43 cases. In contrast, 103 intact cuffs on arthrography showed features on T2-GEI compatible with tendinopathy without rupture, bursitis and degenerative changes. In the absence of very fine surgical or histological correlations for these small lesions, it is impossible, at the present time, to determine the real sensitivity and specificity of MRI.

[Infections caused by Mycobacterium africanum].

Mycobacterium africanum is a bacterial species that was singled out in 1969. Its biochemical and cultural characteristics are intermediary between those of Mycobacterium tuberculosis and Mycobacterium bovis. This bacteria is responsible for tuberculosis in both western and central Africa. We can distinguish between four different types dependent upon the geographical origins of the patients. The extent of this case, with multiple cutaneous and visceral lesions, could not be explained by a past or associated disease or by an immunological defect, be it congenital or acquired.

[Arthroscopy in the treatment of primary acute pyogenic arthritis of the knee in adults. Apropos of 12 cases].

Twelve arthroscopies have been performed in the treatment of acute septic arthritis of the knee. This gave an early visualisation of the cartilaginous and synovial lesions and treatment by lavage, drainage and irrigation of the joint. Using this technique, all the patients were cured of the infection and only one patient showed ultimate limitation of movement of the knee. Arthroscopy made it possible to confirm the diagnosis and to treat the arthritis effectively at an early state and to reduce the mortality and poor functional results of arthrotomy.
