Schwannomas are neoplasms originating from Schwann cells, which are the cells forming nerve sheaths. These neoplasms generally involve peripheral nerves. They rarely affect the gastrointestinal tract and primary colon involvement is extremely rare. The objective of the present paper was to present a case of primary schwannoma of the sigmoid colon, unassociated with von Recklinghausen disease, t...

OBJECTIVE To develop quality indicators to measure asthma care in primary health care. METHOD A modified RAND was used, which included the systematic review of the literature in Embase, Cochrane and Pubmed Quality Agencies and Database. The work group identified the indicators, translated them into Spanish and resolved any duplicates. Each indicator is composed of several dimensions (access t...

primary-like and weakly primary-like submodules are two new generalizations of primary ideals from rings to modules. in fact, the class of primary-like submodules of a module lie between primary submodules and weakly primary-like submodules properly.  in this note, we show that these three classes coincide when their elements are submodules of a multiplication module and satisfy the primeful pr...

let r be a commutative ring and m be an r-module. we say that m is fully primary, if every proper submodule of m is primary. in this paper, we state some characterizations of fully primary modules. we also give some characterizations of rings over which every module is fully primary, and of those rings over which there exists a faithful fully primary module. furthermore, we will introduce some ...

BACKGROUND Access to echocardiography in primary care is limited, but is necessary to accurately diagnose heart failure (HF). AIM To determine the proportion of patients with a GP's diagnosis of HF who really have HF. DESIGN AND SETTING A cross-sectional study of patients in 30 general practices with a GP's diagnosis of heart failure, based on the International Classification of Primary Car...

BACKGROUND As primary care practices evolve into medical homes, there is an increasing need for effective models to shift from visit-based to population-based strategies for care. However, most medical teams lack tools and training to manage panels of patients. As part of a study comparing different approaches to panel management at the Manhattan and Brooklyn campuses of the VA New York Harbor ...

BACKGROUND Although it has been increasingly recognised that patient safety in primary care is important, little is known about the feasibility and effectiveness of different strategies to improve patient safety in primary care. In this study, we aimed to identify the most important strategies by consulting an international panel of primary care physicians and researchers. METHODS A web-based...
