Obstructive sleep apnoea in people with Type 1 diabetes: prevalence and association with micro- and macrovascular complications.

AIMS: Few reports have assessed the relationship between Type 1 diabetes and sleep disorders. The purposes of our study were to determine the prevalence of obstructive sleep apnoea in Type 1 diabetes and to compare the clinical profile of people with Type 1 diabetes with or without obstructive sleep apnoea. METHODS: In this cross sectional study of 67 consecutive people with Type 1 diabetes, we performed polysomnography as part of their yearly check-ups. RESULTS: In our cohort, with a mean BMI of 25.8 ± 4.7 kg/m(2), the prevalence of obstructive sleep apnoea [apnoea-hypopnoea index (AHI) > 10/h] was 46%. Severe obstructive sleep apnoea (AHI ≥ 30/h) was present in 19% of the patients. We found no significant differences in age, sex, body mass index, HbA1c or Epworth sleepiness scale score between people with or without obstructive sleep apnoea. People with obstructive sleep apnoea had a longer course of diabetes mellitus (P < 0.01) and a higher prevalence of retinopathy (P < 0.01), neuropathy (P = 0.05), cardiovascular disease (P < 0.01) and hypertension (P < 0.01). The occurrence of macrovascular complications was independently associated with the presence of OSA [odds ratio (OR) 8.28; 95% confidence interval (CI), 1.56-43.97; P = 0.013] and the duration of diabetes (OR 1.08; 95% CI, 1.02-1.15; P = 0.01). Moreover, retinopathy was independently associated with OSA (OR 4.54; 95% CI, 1.09-18.82; P = 0.04) and the duration of diabetes (OR 1.09; 95% CI, 1.04-1.15; P = 0.001). CONCLUSIONS: The prevalence of obstructive sleep apnoea was high in people with Type 1 diabetes. Obstructive sleep apnoea was independently associated with macrovascular complications and retinopathy. Obesity and excessive daytime sleepiness were uncommon in this population.

[A young woman with granulomatous mastitis: a corynebacteria may be involved in the pathogenesis of these disease]. / Mastite granulomateuse récidivante chez une jeune femme: rôle potentiel de "corynebacterium kroppenstedtii".

INTRODUCTION: The granulomatous mastitis is an inflammatory pseudotumor of the breast of which evolution benign but likely to generate important morphological after-effects among young women. This anatomoclinic entity of dubious etiology until these last years poses a problem of differential diagnosis with other etiologies of granulomatosis and especially with inflammatory carcinoma of the breast. The infectious theory is actually based on solid arguments and mainly explains the physiopathology of this affection. INTERPRETATION: A 26 years old young woman developed an inflammatory tumor of the left breast of which the catch of load by surgery and an antibiotherapy had shown trailing local continuations and of the esthetic after-effects. One year later, a very inflammatory repetition on the level of the right breast was dealt with in a different way: by steroids and immunomodulating drugs associated with iterative punctures with the purulent collections, the objective being to be less dilapidating that left side. The initial answer was rather favorable and encouraging but the purulent reappearance bulky granulomas with sinus way made reconsider the therapeutic attitude and antibiotics were undertaken after description of a lipophilic corynebactery in the material of puncture (Corynebacteria kroppenstedtii). The effectiveness of the amoxicilline introduced on the data of the antibiogram was undeniable. CONCLUSION: This observation illustrates the therapeutic and diagnostic difficulties of an exceptional affection. Potentially accessible to antibiotics it generally requires a joint surgical assumption of responsibility, at the same time to ensure the histological diagnosis but also with a therapeutic aim. The interest of steroids and the immunomodulation by methotrexate is debatable, these treatments cannot however be conceived without antibiotherapy and sometimes surgery.

Altered 40 S ribosomal subunits in omnipotent suppressors of yeast.

The five suppressors SUP35, SUP43, SUP44, SUP45 and SUP46, each mapping at a different chromosomal locus in the yeast Saccharomyces cerevisiae, suppress a wide range of mutations, including representatives of all three types of nonsense mutations, UAA, UAG and UGA. We have demonstrated that ribosomes from the four suppressors SUP35, SUP44, SUP45 and SUP46 translate polyuridylate templates in vitro with higher errors than ribosomes from the normal stain, and that this misreading is substantially enhanced by the antibiotic paromomycin. Furthermore, ribosomal subunit mixing experiments established that the 40 S ribosomal subunit, and this subunit only, is responsible for the higher levels of misreading. Thus, the gene products of SUP35, SUP44, SUP45 and SUP46 are components of the 40 S subunit or are enzymes that modify the subunit. In addition, a protein from the 40 S subunit of the SUP35 suppressor has an altered electrophoretic mobility; this protein is distinct from the altered protein previously uncovered in the 40 S subunit of the SUP46 suppressor. In contrast to the ribosomes from the four suppressors SUP35, SUP44, SUP45 and SUP46, the ribosomes from the SUP43 suppressor do not significantly misread polyuridylate templates in vitro, suggesting that this locus may not encode a ribosomal component or that the misreading is highly specific.

[Acute disulfiram intoxication with severe neurological sequaelae and presenting misleading psychiatric deficiency]. / Intoxication aiguë au disulfirame avec séquelles neurologiques graves et présentation psychiatrique déficitaire trompeuse.

Disulfiram self poisoning is exceptional. The authors report on the case of such an intoxication related to the ingestion of a potentially lethal dose of this drug (30 g) and draw the attention on the following points: 1) The initial signs may be misleading because they include both psychiatrics and neurological signs such as phonation abnormalities, myoclonias and tetraparesia. 2) The evolution is unforseeable with the possible occurrence of severe psychological and motricity sequaelae, associated with bilateral and symetric injuries of the putamen, the palladium and the basal nuclei on CT-scan (or MRI). The pathophysiologic al mechanisms of theses signs are discussed, and the need for disulfiram in the care of alcoholic patients seeking for withdrawal as well.

[Lyme disease disclosed by disabling amyotrophy]. / Maladie de Lyme révélée par une amyotrophie invalidante.

The Lyme disease, which was first found in Lyme, USA, in 1975 is an infectious multi-system disorder whose agent, the Borrelia Burgdorferi, was identified in 1983. Various disease manifestations have been reported since them. We report a case of Lyme disease manifestation in the muscle revealed by serious amyotrophy in the scapular muscles, in the neck and in the trunk with scapula alata accompanied by noctural lumbago which is resistant to non steroïd anti-inflammatory drugs. Electromyography showed patterns of the myogenic type in the serrate anterior and infraspinous muscles on both sides and patterns of the neurogenic peripheral type in the lower extremities. The histological, immunohistochemical and electron-microscopal studies of the muscle biopsy have been without any pathological result. Creatine kinase and aldolase proved normal. Serological antibodies were not significantly increased. A positive diagnosis was obtained by lumbar puncture which showed lymphocytic meningitis, by demonstrating specific antibodies in the cerebrospinal fluid and by Western Blot antibodies analysis. Efficacy of the antibiotic therapy has resulted in a rapid regression of the symptoms, which is a further confirmation of the previous diagnosis.

[Yellow nail syndrome. Apropos of 2 cases. Review of the literature]. / Syndrome des ongles jaunes. A propos de deux cas. Revue de la littérature.

The yellow nail syndrome is a clinical syndrome without specific biological parameters. It is characterized by the following threesome of symptoms: nail abnormalities, primary lymphedema, and pleuropulmonary manifestations. In most cases lymphography shows abnormalities of the lymphatic vessels and spirometry shows a restrictive defect and rarely obstructive disorders. Pathogenesis of this syndrome is still unknown. It is, however, remarkable that the yellow nail syndrome may occur in association with other diseases, the most frequent of which are cancer affections and immune disorders. We report two cases of the yellow nail syndrome which were associated with cancer (neoplasm of the larynx and breast).

[Von Recklinghausen's disease associated with pancreatic somatostatinoma]. / Maladie de Von Recklinghausen associée à un somatostatinome pancréatique.

INTRODUCTION: Pancreatic somatostatinoma is a rare entity and its association with Von Recklinghausen's disease has only been described on two occasions. We report a new observation, with clinical and evolving status differing from those described in isolated cases of somatostatinoma. OBSERVATION: A 28 year-old man presenting with familial Von Recklinghausen's disease, had suffered for 10 years from paroxysmic abdominal pain. He was hospitalized for intense pain. Imaging revealed a retroperineal tumoral formation. Following duodenopancreatectomy, somatostatinoma was diagnosed. Diffuse metastatic miliary was revealed and multiple glandular metastases. DISCUSSION: Other than the rarity of the morbid association (pancreatic somatostatinoma and Von Recklinghausen's disease) described, this case is particular in that the patient was very young, symptomatology was unapparent and tumoral evolution was minimal.

[Campylobacter fetus meningitis in adults]. / Méningite à Campylobacter fetus chez l'adulte.

Campylobacter fetus is an uncommon cause of meningitis in the adult. We report a case observed in an 84-year-old man with alcoholic cirrhosis. The patient presented fever, jaundice and a state of mental confusion. Blood and cerebrospinal fluid cultures identified Campylobacter fetus sensitive to several antibiotics. Ciprofloxacine-ceftriaxone combination replaced the antibiotics prescribed empirically prior to identification and led to regression of the fever and normal mental status within 4 days. Spinal tap on day 7 showed 20 white cells, 85% lymphocytes and normal protein level. Unfortunately, the patient later developed edema and ascitis with major jaundice. Oligo-anuria could not be controlled and the patient died two weeks after admission. Campylobacter fetus meningitis is predominantly seen in men, mean age of onset 50 years. Clinical signs are not specific and diagnosis can only be obtained on the basis of cerebrospinal fluid results. Adapted antibiotics are required.

[Budd-Chiari syndrome with inferior vena cava stenosis]. / Un syndrome de Budd-Chiari par sténose cave inférieure.

BACKGROUND: Stenosis of the inferior vena cava is a rare cause of Budd-Chiari's syndrome. We report on such a case related to a specific cause with a dramatic improvement after endovascular treatment. CASE REPORT: A 53-year old woman was admitted to hospital because she demonstrated circulatory collapse, inferior limbs edema and post-prandial epigastralgia. These signs were related to the occurrence of a stenosis of the sus-hepatic segment of the inferior vena cava related to the presence of the distal part of a catheter. An angioplasty with the insertion of a stent was followed by a total recovery with a one-year survey. CONCLUSION: Angioplasty with the insertion of a stent should be considered in a Budd-Chiari syndrome related to the stenosis of the inferior vena cava. This option should be evaluated with reference to classic surgical techniques.

[Recurrent nerve palsy due to Lyme disease: report of two cases]. / Paralysie du nerf récurrent au cours d'une maladie de Lyme : à propos de deux observations.

INTRODUCTION: Neuroborreliosis can be a difficult diagnosis which requires epidemiologic, clinical and biologic arguments. CASE REPORTS: We report two patients who presented with a recurrent laryngeal nerve palsy with positive Lyme serology and favorable outcome after antibiotic therapy. In one case, a lymphocytic meningitis with intrathecal production of specific antibodies was evidenced. CONCLUSION: Recurrent laryngeal nerve palsy is an uncommon manifestation of neuroborreliosis. Lyme serology is an important tool when neurologic disorder occurs because of an atypical course of Lyme disease.
