Ganglioneuroma: To Operate or Not to Operate

European Journal of Pediatric Surgery, 2013
Ganglioneuroma (GN) is a benign, differentiated variety of neurogenic tumor. It is often asymptomatic and may be diagnosed by serendipity. Surgical removal is the treatment of choice. However, it has been suggested that postoperative complications and sequelae might outweigh the benefits of this approach. The purpose of the present study was to examine

Current Concepts in the Operative Management of Acromioclavicular Dislocations: A Systematic Review and Meta-analysis of Operative Techniques

American Journal of Sports Medicine, 2018
Background: Acromioclavicular (AC) instability is a frequent injury affecting young and athletic populations. Symptomatic, high-grade dislocations may be managed by a myriad of operative techniques that utilize different grafts to achieve reduction ...

Impact of hospital volume on operative mortality for major cancer surgery.

Journal of the American Medical Association (JAMA), 1998
CONTEXT Hospitals that treat a relatively high volume of patients for selected surgical oncology procedures report lower surgical in-hospital mortality rates than hospitals with a low volume of the procedures, but the reports do not take into account ...

Operations and Operatives

2014
Operation RUVANDIZ-SCHLUCHT (ROWANDUZ GORGE) is said to have been a detailed scheme originally submitted to Hans-Otto Wagner of Abwehr II in 1941 by Paul Leverkuehn of KONO in Istanbul for a 2–3-man parachute team to carry out the demolition of bridges on the 185 km-long, strategic asphalt road, known even today as the Hamilton Road, constructed by the

Pituitary Incidentaloma: to Operate or Not to Operate ?

Acta Chirurgica Belgica, 2012
The wide use of sophisticated imaging techniques has led to the discovery of asymptomatic pituitary lesions, which are called 'incidentalomas'. Their global prevalence averages 10% whereas that of macroadenomas (> 10 mm) is less than 1%. The most frequently encountered lesions are non-functioning adenomas followed by Rathke's cleft cysts. Physiological

Operations on Closure Operators

1995
Despite the powerful continuity condition, the notion of closure operator is very general. It is therefore important to provide tools for improving a given operator. Fortunately, there is a natural lattice structure for closure operators that allows us to distinguish between properties stable under meet (idempotency, hereditariness, productivity), and ...

Operations with Hyponormal Operators

1989
It is the aim of the present chapter to collect some of the operations which preserve the class of hyponormal operators. We have already seen in Example II.2.1 that the square of a hyponormal operator may not be hyponormal. Thus the analytic functional calculus is excluded from these operations.

Operations with monotone operators and the monotonicity of the resulting operators

Monatshefte für Mathematik, 2015
In this paper we provide estimates for the parameters of monotonicity of two composed operators as well as for the sum of two operators. The estimates are given in terms of the parameters of monotonicity of the involved operators and they produce examples of h-monotone operators which are not Minty–Browder monotone. As an application to these estimates
