Non-typhi Salmonella enterica urinary tract infections.

OBJECTIVE: Non-typhi Salmonella enterica urinary tract infections (UTIs) are not frequent and rarely reported in the literature. We aimed to characterize clinical presentations and risk factors for the infection. PATIENTS AND METHODS: We performed a retrospective study of non-typhi Salmonella enterica strains isolated from urine cytobacteriological examinations (UCBE) collected between January 1, 1996 and October 30, 2014 and analyzed by the microbiology laboratories of the university hospitals of the western part of Île-de-France and of Paris, France. RESULTS: Twenty UCBEs positive for non-typhi Salmonella enterica were analyzed. The sex ratio was 0.53 and the average age of patients was 57 years. Clinical presentations were acute pyelonephritis, acute cystitis, and prostatitis. Eight cases of bacteremia were identified. Diarrhea was observed in half of patients, either before the UTI or simultaneously. No patient required to be transferred to the intensive care unit. Immunodeficiency and/or diabetes were observed in eight patients. Three patients presented with a uropathy. Prescribed antibiotics were third generation cephalosporins and fluoroquinolones. The average treatment duration was 20 days. A spondylitis and a purulent pleurisy were observed and deemed related to the UTI. Patient outcome was always favorable following treatment prescription. CONCLUSION: Non-typhi Salmonella enterica UTIs are rare. They are mainly observed in elderly patients presenting with immunodeficiency or an underlying urological disorder.

[Sleepiness and sleep apnea syndrome. Analysis of 188 questionnaires (102 patients and 86 controls)]. / Somnolence et syndrome d'apnées du sommeil. Analyse de 188 questionnaires (102 malades et 86 témoins).

A questionnaire was given to 102 obstructive sleep apnea patients and 86 controls. A somnolence index was defined by averaging the scores of the answers to eleven questions concerning sleepiness. This index separated patients and controls (P < 0.0001). It was correlated with the apnea + hypopnea index (r = 0.32, P < 0.001), the body mass index (r = 0.45, P < 0.001) and with an objective measurement of sleepiness obtained from a modified multiple sleep latency test (r = -0.54, P < 0.001). Depending upon the current occupation, the tendency to fall asleep decreased in the following order: watching TV, passenger in a means of transport, reading, attending a show, attending a meeting, driving a car, and eating. This order is the same in patients and controls, irrespective of their "overall sleepiness". Thus, the circumstances of falling asleep are indicative of the severity of sleepiness.

[[Emergency pediatric EEG in mental confusion, behavioral disorders and vigilance disorders: a retrospective study]. / L'EEG d'urgence en pédiatrie dans les troubles de la vigilance, la confusion mentale et les troubles du comportement: étude rétrospective.

Recording of electroencephalogram (EEG) is of value to estimate vigilance states in children as in adults. In order to determine the diagnostic and prognostic value of emergency EEG in case of mental confusion, behavioral disorders and vigilance disorders in childhood, we conducted a retrospective study in 397 children (aged 2 months to 16 years). EEG was recorded less than 24 hours after an emergency consultation for acute confusion or acute behavioral disorder (n = 106) or after admission to the intensive care unit for comatose stage (n = 291). EEG gave diagnostic indications mainly in case of convulsive pathology or hepatic encephalopathy. In comatose children, we established a 4-stage EEG scale of increasing severity. This classification was compared to EEG scales already published in the literature and appeared very similar to that from Pampiglione and Harden, established in 150 children after cardiac arrest. A highly poor prognostic value was associated with burst-suppression post-anoxic patterns and with isoelectric records signaling brain death. Our classification of emergency EEG patterns is mainly helpful in these two situations, but does not exclude strict and repeated clinical and EEG follow-up in other cases, as a relatively preserved initial EEG may later deteriorate.

[Indications of electroencephalogram in the newborn]. / Indications de l'électroencéphalogramme en période néonatale. Recommandations du groupe de neurophysiologie clinique de l'enfant.

The electroencephalogram (EEG), an easy-to-use and non invasive cerebral investigation, is a useful tool for diagnosis and early prognosis in newborn babies. In newborn full term babies manifesting abnormal clinical signs, EEG can point focal lesions or specific aetiology. EEG background activity and sleep organization have a high prognostic value. Tracings recorded over long period can detect seizures, with or without clinical manifestations, and differentiate them from paroxysmal non epileptic movements. The EEG should therefore be recorded at the beginning of the first symptoms, and if possible before any seizure treatment. When used as a neonatal prognostic tool, EEG background activity is classified as normal, abnormal (type A and type B discontinuous and hyperactive rapid tracing) or highly abnormal (inactive, paroxysmal, low voltage plus theta tracing). In such cases, the initial recording must be made between 12 and 48 h after birth, and then between 4 and 8 days of life. Severe EEG abnormalities before 12 h of life have no reliable prognostic value but may help in the choice of early neuroprotective treatment of acute cerebral hypoxia-ischemia. During presumed hypoxic-ischemic encephalopathy, unusual EEG patterns may indicate another diagnosis. In premature newborn babies (29-32 w GA) with neurological abnormalities, EEG use is the same as in term newborns. Without any neurological abnormal sign, EEG requirements depend on GA and the mother's or child's risk factors. Before 28 w GA, when looking for positive rolandic sharp waves (PRSW), EEG records are to be acquired systematically at D2-D3, D7-D8, 31-32 and 36 w GA. It is well known that numerous and persistent PRSW are related to periventricular leukomalacia (PVL) and indicate a bad prognosis. In babies born after 32 GA with clinically severe symptoms, an EEG should be performed before D7. Background activity, organization and maturation of the tracing are valuable diagnosis and prognosis indicators. These recommendations are designed (1) to get a maximum of precise informations from a limited number of tracings and (2) to standardize practices and thus facilitate comparisons and multicenter studies.

Decrease in haematocrit with continuous positive airway pressure treatment in obstructive sleep apnoea patients.

Previous preliminary results have shown an overnight decrease in haematocrit and red cell count after the first night of treatment with nasal continuous positive airway pressure (CPAP) in obstructive sleep apnoea (OSA) patients. The present study was designed to confirm these preliminary data, and to analyse the long-term effects of CPAP. The haematocrit and red cell count (RCC) were measured in 80 OSA patients on two consecutive mornings, after an untreated night and after a CPAP treatment night. The haematocrit and RCC significantly decreased with CPAP (from 44.0 +/- 0.5 to 42.4 +/- 0.4%, p less than 0.0001 and from 4.769 +/- 0.051 to 4.597 +/- 0.052 x 10(12) red cells.l-1, p less than 0.0001, respectively). Neither the decrease in haematocrit nor the decrease in RCC were correlated with the decrease in urine volume or flow which occurred with CPAP. Thirty five of these patients remained untreated for 45 +/- 4 days, before home treatment with CPAP was initiated. The haematocrit and RCC had returned to values close to those before initial treatment and decreased again after the first treatment night. Twenty one of the patients were re-evaluated after at least one year of home treatment with CPAP, again on two consecutive nights either with CPAP or untreated. The follow-up, post-CPAP haematocrit and RCC were slightly and nonsignificantly higher than after the baseline CPAP night, but still lower than after the baseline untreated night (p less than 0.02). After the untreated follow-up night, no significant change in haematocrit was observed.(ABSTRACT TRUNCATED AT 250 WORDS)

Acute inflammatory demyelinating polyradiculopathy in children: clinical and electrodiagnostic studies.

Clinical and electrophysiological features in 43 children with acute inflammatory demyelinating polyradiculoneuropathy (AIDP) were retrospectively studied. More than one-third of these children were less than 3 years old. Some distinctive clinical features specific to adults or to children were identified. Initial symptoms such as ataxia and severe limb or back pain were more frequent in children. By using the criteria suggested here, according to our neurophysiological findings, the diagnosis of AIDP could be proposed as early of the first days of illness in 90% of the children and is confirmed during the second week. The neurophysiological evolution was very similar in children and adults except that recovery occurred sooner in children. Prognosis was better in childhood (complete recovery in all but 2 patients with minor disabilities).

Nocturnal pollakiuria is a symptom of obstructive sleep apnea.

An increased urine excretion has been reported in obstructive sleep apnea (OSA) patients, but it is not clear whether it results in an increased number of nocturnal micturitions. The present study was aimed at investigating the frequency of nocturnal micturitions in OSA patients using a standardized questionnaire prospectively given to 102 OSA patients and 86 healthy male subjects. The frequency of nocturnal micturitions was significantly greater in the OSA patients than in the healthy subjects (more than 70% of the OSA patients with an apnea+hypopnea index > 50 reported nocturnal micturitions more than twice a week versus less than 25% of the healthy subjects, p < 0.0001). The number of nocturnal micturitions was also greater in the OSA patients than in the healthy subjects. There was an effect of age on the frequency of nocturnal micturitions; however, when age-matched subsamples were considered, there was still a significant difference between OSA patients and healthy subjects. In a subgroup of 25 OSA patients reevaluated after at least 1 year of home treatment with nasal continuous positive airway pressure the reported frequency of nocturnal micturitions had significantly decreased (p < 0.001). These results suggest that investigations aimed at establishing a diagnosis of OSA should be part of the work-up of patients complaining of nocturnal pollakiuria.
