The impact of hospital structure and restructuring on the nursing workforce.

OBJECTIVE: Health systems throughout much of the world have been subject to 'reform' in recent years as countries have attempted to contain the rapidly rising costs of health care. Changes to hospital structures (restructuring) have been an important part of these reforms. A significant impact of current approaches to restructuring is the loss of, or changes to, nursing management roles and functions. SETTING: Australian hospitals PRIMARY ARGUMENT: Little evaluation has been undertaken to determine the impact of hospital structure and organisational restructuring on the nursing workforce. CONCLUSIONS: There is some indication that nurses have experienced a loss of key management positions, which may impact on their capacity to ensure that adequate and safe care is provided at the ward level.     

Combined percutaneous antegrade and cystoscopic retrograde approach in the treatment of distal ureteric fistulae

Purpose To determine the efficacy of a cystoscopic approach, as definitive treatment of ureteral fistulae, after failure of antegrade ureteral stent insertion.Methods Of 43 ureter fistulae encountered over 4 years, 10 postoperative and/or postradiotherapy fistulae could not be stented via an antegrade approach alone. A cystoscopic approach was used, with the antegrade approach available as back-up, if necessary.Results In two patients the ureteral orifice could not be visualized cystoscopically, thus precluding the retrograde approach. In the eight remaining patients, the retrograde approach alone never allowed successful stenting. In six patients, combined antegrade and retrograde approaches permitted stent insertions. In three of those six patients, a complex catheterization procedure was necessary. In two patients the combined approach failed altogether. Therefore, 6 of 10 patients underwent a successful stenting procedure with the combined approach; all ultimately closed the fistula.Conclusion Antegrade stent insertion remains the treatment of choice for ureteral leaks. If the antegrade approach fails, the retrograde approach alone is not likely to be successful. Instead, a combination of both approaches often does succeed.     

An unusual case of bilateral auriculotemporal syndrome presenting to an allergist.

BACKGROUND: Auriculotemporal syndrome (AS) is an uncommon disorder that may present with facial erythema with chewing food. METHODS: We report a patient referred to an allergist to rule out allergy as a reason for food-associated bilateral facial flushing. She was subsequently found to have bilateral AS. RESULTS: The symptoms of AS may overlap those associated with food allergy. There are only a few published cases of bilateral AS. CONCLUSIONS: Allergists should be aware of bilateral AS and the clinical spectrum of this disorder as AS patients may be referred to allergists to rule out food allergy.     

Cystic pancreatic tumors: CT and sonographic assessment

Thirty-five CT scans and 23 sonograms of 45 pathologically proved pancreatic cystic neoplasms (16 microcystic adenomas, 17 mucinous [macrocystic] cystadenomas, and 12 mucinous [macrocystic] cystadenocarcinomas) in 43 patients were retrospectively and blindly reviewed. Radiologic findings and their usefulness in differentiating microcystic from mucinous subtypes were assessed. The number of cysts within the tumors (more than six in microcystic adenomas and six or fewer in mucinous cystadenomas and cystadenocarcinomas) and the diameter of the majority of cysts within the tumor (less than or equal to 2 cm in microcystic adenomas and greater than 2 cm in mucinous tumors) were the most helpful radiologic findings in differentiating tumor types. Calcification was present in 38% of microcystic adenomas, 18% of mucinous cystadenomas, and 8% of mucinous cystadenocarcinomas by CT. Calcification was not definitely identified on any of the sonograms. A central scar was identified in only two (13%) of 16 microcystic adenomas. Blind retrospective review was often able to correctly classify tumors as either microcystic (CT, 93%; sonography, 78%) or mucinous (CT, 95%; sonography, 93%). All tumors with a typical appearance on either CT or sonography were categorized correctly. Cystic pancreatic tumors may be difficult to prospectively separate from other types of pancreatic cysts. Assuming a cystic neoplasm is present, it often can be classified correctly as microcystic or mucinous (macrocystic) by using the above criteria.     

The heterogeneity of the long-term course of schizophrenia

Research has demonstrated considerable heterogeneity in the long-term course of schizophrenia. In the period preceding the onset of frank psychosis (onset), patients vary relative to the rapidity of onset, the presence or absence of associality, and the presence or absence of semipsychotic symptoms. Following the onset of psychosis (middle course), patients may suffer from episodic or unremitting psychosis, and may or may not exhibit the deficit syndrome. In late adult life (late course), patients vary relative to the presence or absence of an improvement in psychosis and social capability. The usual approach to the study of putative course subtypes is to define a subtype by a number of features; they may include features of more than one epoch. In addition, the course of psychosis has not been distinguished from enduring personality impairments in these subtypes. Another approach to defining putative course subtypes would be based on dichotomizing patients according to the presence or absence of a particular feature of a single epoch. This second approach has important advantages: the availability of larger study populations and a diminished liability for confounding due to the correlates of features other than those under scrutiny.
