Kidney outcomes in Shiga toxin-associated hemolytic uremic syndrome in childhood: A retrospective single-center study from 1999 to 2017: Kidney outcomes in typical hemolytic uremic syndrome in childhood.

Background: Shiga toxin-associated hemolytic uremic syndrome (STECHUS) is the main cause of acute kidney injury in children and may be responsible for adverse outcomes despite an apparent quiescent period.

Objective: To describe the medium- and long-term kidney outcomes of pediatric STECHUS in a French region.

Methods: A single-center, descriptive, retrospective study of STECHUS cases that occurred at Besançon University Hospital between 1999 and 2017 in children up to 17 years of age was conducted.

Guidelines for data-driven approaches to study transitions in multiscale systems: The case of Lyapunov vectors.

This study investigates the use of covariant Lyapunov vectors and their respective angles for detecting transitions between metastable states in dynamical systems, as recently discussed in several atmospheric sciences applications. In a first step, the needed underlying dynamical models are derived from data using a non-parametric model-based clustering framework. The covariant Lyapunov vectors are then approximated based on these data-driven models.

Neurodevelopmental consequences of early plasma sodium changes in very preterm infants.

Background: Sodium fluctuations in very preterm neonates and their neurodevelopmental consequences are not well described.

Methods: We assessed the changes in plasma sodium and glucose in the first days of life in very preterm neonates and studied the association of glucose-corrected plasma sodium fluctuations on neurodevelopmental outcomes. We included 147 consecutive neonates born before 29 weeks of gestation in our center and retrospectively obtained plasma sodium, glucose, and glucose-corrected sodium levels.

[Selective laser trabeculoplasty: results after a first and a second session, overall comparison and results for three indications].

Purpose: To compare the results obtained with SLT trabeculoplasty after an initial treatment (SLT-1) and after a second treatment (SLT-2). Subgroup analysis according to trabecular pigmentation and the existence of a high myopia.

Materials And Methods: Retrospective study of 77 patients, 152 SLT sessions performed in the Ophthalmology Department of Clermont-Ferrand University Medical Center, 118 SLT-1, 34 SLT-2.

[Case report of a 2-year-old child with palpebral rhabdomyosarcoma].

Rhabdomyosarcoma is an extremely virulent rare tumor whose early diagnosis considerably improves survival and visual prognosis. We report the case of a 2-year-old child with levator palpebrae superioris muscle rhabdomyosarcoma revealed by a sudden and isolated blepharoptosis. Initially, clinical and imaging investigations did not show any abnormality but a painful tumor with some hematoma quickly developed, so the investigations were repeated.

Assessment of topographic brachial plexus nerves variations at the axilla using ultrasonography.

Background: The aim of this study was to describe topographic variations in the arrangement of the four main brachial plexus nerves at the junction of the axilla and the upper part of the arm.

Methods: In 153 patients undergoing upper arm surgery using axillary block, we studied nerve arrangements with a three-step approach, combining: (A) cross-sectional ultrasound imaging using a 12 MHz linear ultrasound probe; (B) distal shift of the ultrasound scanhead from the axilla to the elbow joint following the paths of individual nerves; and (C) identifying the distal motor response to electrical nerve stimulation of each nerve. These results were then converted into a 12-section pie chart with the axillary artery (AA) as the axis.

[Interferon-related retinopathy in a man with chronic hepatitis C].

A 50-year-old diabetic man receiving insulin, and suffering from chronic hepatitis C treated with interferon alfa and ribavirin presented with an acute peripheral scotoma and retinopathy associated with interferon therapy. When the treatment was interrupted, all the clinical symptoms and the test abnormalities returned to normal. If the association of interferon alpha and ribavirin increase the incidence of retinopathy, diabetes, and hypertension are also risk factors.

[An optic nerve glioma in a 4-month-old child].

The optic nerve glioma is a relatively rare pathology in children and only a few cases have been described in infants. This paper reports the symptoms of this exceptional case in a 4-month-old child and reviews the differential diagnoses at this age. Finally, we discuss the diagnosis and therapeutic possibilities.

[Solitary plasmacytoma simulating pituitary adenoma].

A case of solitary plasmocytoma of the sphenoid is reported, masquerading as pituitary adenoma. At the time of surgery, the patient had no findings of multiple myeloma. The tumor was removed by trans-sphenoidal route and radiotherapy delivered.

[Choice of a central analgesic for anesthesia with spontaneous respiration].

The ventilatory effects of tramadol (T) and nefopam (N) are evaluated in anesthetized patients with enflurane in a closed circuit breathing system and compared with the effects of pentazocine (P). The following parameters tidal volume (VT), minute ventilation (V), CO2 (capnometry) occlusion pressure (OP), ventilatory response to hypercarbia are recorded after 30 minutes of anaesthesia, before and after repeated injections of the analgesics, P: 15 mg, N: 40 mg, T: 100 mg are injected I.V.

[Anesthesia programmed by enflurane].

A microcomputer type 6502 is the central unity of a volatile anaesthetic injector for use in a closed circuit breathing system. Estimated calculations for quantity of anaesthetic liquid are done in agreement with the formula of J.W.
