Risk of Reopening of the Mesenteric Defects After Routine Closure in Laparoscopic Roux-en-Y Gastric Bypass: a Single-Centre Experience.

Purpose: Small bowel obstruction (SBO) due to internal hernias (IH) is a well-recognised complication after laparoscopic Roux-en-Y gastric bypass (LRYGB). Routine closure of the mesenteric defects (MDs) is recommended to reduce the risk of IH and subsequent SBO. However, data about the rates of reopening of the MDs after LRYGB is scarce.

Macrophage activation syndrome triggered by active systemic lupus erythematosus : Successful treatment by interleukin-1 inhibition (anakinra).

This article presents a case of fulminant macrophage activation syndrome (MAS) as a rare complication of active systemic lupus erythematosus in a 33-year-old female patient. Initial presentation showed severe lupus disease exacerbation with renal involvement, hemolytic anemia, and neuropsychiatric changes. Early therapy focused on broad immunosuppression (high-dose corticosteroids and cyclophosphamide); however, disease remission could not be achieved.

Magma transport in sheet intrusions of the Alnö carbonatite complex, central Sweden.

Magma transport through the Earth's crust occurs dominantly via sheet intrusions, such as dykes and cone-sheets, and is fundamental to crustal evolution, volcanic eruptions and geochemical element cycling. However, reliable methods to reconstruct flow direction in solidified sheet intrusions have proved elusive. Anisotropy of magnetic susceptibility (AMS) in magmatic sheets is often interpreted as primary magma flow, but magnetic fabrics can be modified by post-emplacement processes, making interpretation of AMS data ambiguous.

The Scent of Blood: A Driver of Human Behavior?

The scent of blood is potentially one of the most fundamental and survival-relevant olfactory cues in humans. This experiment tests the first human parameters of perceptual threshold and emotional ratings in men and women of an artificially simulated smell of fresh blood in contact with the skin. We hypothesize that this scent of blood, with its association with injury, danger, death, and nutrition will be a critical cue activating fundamental motivational systems relating to either predatory approach behavior or prey-like withdrawal behavior, or both.

Acetazolamide sensitive tissue calcification and aging of klotho-hypomorphic mice.

Unlabelled: Klotho, a protein expressed mainly in the kidney, is required for the inhibitory effect of FGF23 on renal 1,25(OH)2D3 formation. Klotho counteracts vascular calcification and diverse age-related disorders. Klotho-hypomorphic mice (kl/kl) suffer from severe vascular calcification and rapid aging.

[Surgical treatment of 3- and 4-part fractures of the humeral head using a polyaxial-locking plate: results and patient satisfaction].

Introduction: In recent years, new angle-stable plate implants with polyaxial screw direction were developed with the aim of an improved treatment of displaced 3- and 4-part fractures of the proximal humerus. There are only a few studies available about polyaxial implants in the treatment of 3- and 4-part proximal humerus fractures. Therefore, the aim of this study was to evaluate clinical results and complications of open reduction and internal fixation of displaced 3- and 4-part fractures using a polyaxial plate.

Clinical outcome and complications using a polyaxial locking plate in the treatment of displaced proximal humerus fractures. A reliable system?

Introduction: The surgical treatment of displaced proximal humeral fractures (ORIF) is a perpetual challenge to the surgeon. For this reason, the principle of polyaxiality was developed to provide an improved primary stability of the fracture through better anchorage of the screws, especially in osteoporotic bone. The aim of this study was to present clinical results with the polyaxial locking plate in the operative treatment of proximal humerus fractures in order to determine whether the technique of polyaxiality leads to better functional outcome and lower complication rates in comparison to monoaxial plates in the literature.

Recording of peak endocardial acceleration in the atrium.

Background: The important role played by peak endocardial acceleration (PEA or sonR) in hemodynamic monitoring of cardiac resynchronization therapy (CRT) was recently highlighted in several studies with the sensor embedded in a right ventricular (RV) lead tip. This study examined the short- and long-term reliability of a right atrial (RA) sonR sensor.

Methods: RA and RV sonR signals were measured from RA and RV leads respectively, at implant and up to 12 months of follow-up, in 19 recipients of either single chamber pacemakers or CRT systems.

Incomplete bundle-branch block and ST-segment elevation: syndrome associated with sustained monomorphic ventricular tachycardia in patients with apparently normal heart.

This paper reports on three cases of patients with an apparently normal heart admitted for sustained monomorphic ventricular tachycardia. The only abnormal finding showed in the electrocardiogram (ECG) in sinus rhythm that exhibited an entity associated with incomplete right bundle-branch block and persistent ST-segment elevation. The ECG entity was variable and disappeared transiently.

[Syncope and fainting in patients with a cardiac pacemaker].

When a patient with a cardiac pacemaker presents with syncope or faintness, one's first thought should be failure of the pacemaker. If the abnormality is not apparent, the patient needs a full cardiological investigation, including "active" electrocardiographic recordings: magnet test, programming, or even Holter monitor should be performed in order to exclude the responsibility of the pacemaker. Modern pacemakers can fail and cause syncope, especially if they have been inadequately or incorrectly regulated.

[Tachycardia and ensuing electrosystole].

The benign or severe nature of a ventricular extrasystole depends on a number of parameters which involve the pathophysiological mechanism of the extrasystole: re-entry, exaggerated normal or abnormal automatism and therefore the presence or absence of an underlying cardiac disease. The prognosis depends directly on the morphology, the number and the characteristics of the arrhythmia. Various investigations are often necessary to evaluate this prognosis, including 24 hour Holter monitoring, stress test and electrophysiological investigations.

[Physiologic stimulation: the future or a passing phase?].

Pacing techniques achieving normal AV synchrony are termed "physiologic". All rely on an atrial pacing or/and pacing system usually coupled with ventricular pacing. The major advantage is haemodynamic, usually related to the varying ventricular pacing rate obtained with atrial sensing systems only.

[A chronological linkage technic of records and use of the obtained information. Application to the functional control of cardiac stimulators].

The application of information processing to the study of the evolution of the patient's state requires the constituting of a file which contains the values of different items as functions of time. There are many methods for doing this and most of them appeal to the construction of a complex database. The technique presented in the paper paper tries at first to constitute, for each patient, some records, of which every one corresponds to a determined "operation' (the term "operation' is taken in the wide sense; example: consultation, surgical intervention,.

[French evaluation of cardiac stimulation].

A national enquiry into the problems related to definitive cardiac pacemakers, carried out in 1975, has yielded certain essential findings: the number of first-time implantations of pacemakers has been increasing by about 20% per annum; 92% of electrodes are currently implanted by an endocavitary technique, thoracotomy having now practically been abandoned; 90% of pacemakers implanted in 1975 were threshold models, inhibited by a QRS complex; the indications have become progressively wider, and are essentially related with the various forms of bradycardia, most frequently those due to atrio--ventricular block. In 1976, we have now reached a figure of about 200 new implantations of pacemakers per million inhabitants; those using lithium are increasingly superceding the mercury and isotope models.
