Establishing a nurse-based psychiatric CL service in the accident and emergency department of a general hospital in Germany.

INTRODUCTION: Patients with mental health problems in accident and emergency departments (A&E) are frequent users and often difficult to handle. Failure in managing these patients can cause adversities to both patients and A&E staff. It has been shown that nurse-based psychiatric consultation-liaison (CL) services work successfully and cost effectively in English-speaking countries, but they are hardly found in European countries. The aim of this study was to determine whether such a liaison service can be established in the A&E of a German general hospital. We describe structural and procedural elements of this service and present data of A&E patients who were referred to the newly established service during the first year of its existence, as well as an evaluation of this nurse-led service by non-psychiatric staff in the A&E and psychiatrists of the hospital's department of psychiatry. SUBJECTS AND METHODS: In 2008 a nurse-based psychiatric CL-service was introduced to the A&E of the Königin Elisabeth Herzberge (KEH) general hospital in the city of Berlin. Pathways for the nurse's tasks were developed and patient-data collected from May 2008 till May 2009. An evaluation by questionnaire of attitudes towards the service of A&E staff and psychiatrists of the hospital's psychiatric department was performed at the end of this period. RESULTS: Although limited by German law that many clinical decisions to be performed by physicians only, psychiatric CL-nurses can work successfully in an A&E if prepared by special training and supervised by a CL-psychiatrist. The evaluation of the service showed benefits with respect to satisfaction and skills of staff with regard to the management of psychiatrically ill patients. CONCLUSION: Nurse-based psychiatric CL-services in A&E departments of general hospitals, originally developed in English-speaking countries, can be adapted for and implemented in a European country like Germany.

Cross-sectional survey of disturbed behaviour in patients in general hospitals in Leeds.

AIM: To describe the prevalence and nature of disturbed behaviour, in the general hospital setting. METHOD: A cross-sectional survey was conducted, from July to October 2006, in all adult inpatient wards within the six general hospitals in Leeds of patients presenting with disturbed behaviour in the preceding 7 days. Disturbed behaviour was defined as behaviour interfering with care of the patient or with that of other patients, or behaviour that placed the patient, the staff or others at risk. Anonymised data were collected using a semi-structured questionnaire. RESULTS: All of the 87 hospital wards were studied, containing a total of 1773 beds. 42 male and 26 female patients (n = 68) were identified by nursing staff as patients with disturbed behaviour in the time period covered, with 33 patients being 65 years of age). An almost equal proportion of the younger and older patient groups placed themselves or others at risk. In the majority of cases, aggressive behaviour by patients was directed towards staff rather than other patients. 60 patients required additional staff time due to the disturbed behaviour, 34 required additional medication, and 22 patients were referred to liaison psychiatry. CONCLUSIONS: Disturbed behaviour presents in the general hospital in less than 4% of patients, both above and below the age of 65 years, but consumes a disproportionate amount of resources. Responses required to manage this include additional medication, additional staff time or other interventions. The quantity and nature of disturbed behaviour in the general hospital have implications for effective service provision and development.

Stressful life events and difficulties and onset of breast cancer: case-control study.

OBJECTIVE: To determine the relation between stressful life events and difficulties and the onset of breast cancer. DESIGN: Case-control study. SETTING: 3 NHS breast clinics serving west Leeds. PARTICIPANTS: 399 consecutive women, aged 40-79, attending the breast clinics who were Leeds residents. MAIN OUTCOME MEASURES: Odds ratios of the risk of developing breast cancer after experiencing one or more severe life events, severe difficulties, severe 2 year non-personal health difficulties, or severe 2 year personal health difficulties in the 5 years before clinical presentation. RESULTS: 332 (83%) women participated. Women diagnosed with breast cancer were no more likely to have experienced one or more severe life events (adjusted odds ratio 0.91, 95% confidence interval 0.47 to 1. 81; P=0.79); one or more severe difficulties (0.86, 0.41 to 1.81; P=0.69); a 2 year severe non-personal health difficulty (0.53, 0.12 to 2.31; P=0.4); or a 2 year severe personal health difficulty (2.73, 0.68 to 10.93; P=0.16) than women diagnosed with a benign breast lump. CONCLUSION: These findings do not support the hypothesis that severe life events or difficulties are associated with onset of breast cancer.

Algodystrophy after Colles fractures is associated with secondary tightness of casts.

We describe a direct method of measuring the tightness of plaster casts. Tightness was measured weekly in 23 consecutive patients with Colles' fractures. Six had objective signs of algodystrophy nine weeks after the fracture. In these patients the plaster cast was significantly tighter during the first three weeks than in patients who did not develop algodystrophy. The complex relationship between these findings is discussed.

Perioperative blood transfusion increases the risk of recurrence in colorectal cancer.

A retrospective study was conducted on 519 patients undergoing curative resection for colorectal carcinoma between 1969 and 1980. Recurrence was diagnosed in 214 patients (41.2 percent), 179 of whom (34.5 percent) had received blood transfusions and 35 of whom (6.7 percent) had not (P less than .001). Exclusion of the right-sided colonic tumors still showed that recurrence was more common in transfused than nontransfused patients (135 [47.2 percent] vs. 25 [22.5 percent]; P less than .001). Recurrence in patients transfused only during surgery (N = 201) was higher than in nontransfused patients (P less than .001) and, similarly, all patients transfused during surgery (N = 297) had an increased risk (P less than .001). Among patients with rectal cancer, transfusion increased the risk of recurrence in those treated by abdominoperineal resection (P less than .02), but this was not the case in those treated by sphincter-saving resection (P = .2). Hierarchical log linear analysis of all dependent factors (Dukes' stage, histologic grade, age, sex, site, elective, or emergency procedure) showed that Dukes' stage and blood transfusion had the most significant effects on the development of recurrence (chi 2 = 54.04, df = 6, P less than .0001 and chi 2 = 13.93, df = 3, P less than .003). The risk of recurrence following curative surgery for colorectal cancer is markedly increased by blood transfusion on the day of operation.

D-penicillamine induced myasthenia gravis. Its relevance for the anaesthetist.

The case of a 57-year-old woman with rheumatoid arthritis is presented to illustrate the rare occurrence of a myasthenic syndrome induced by D-penicillamine, which led to prolonged (5.25-h) postoperative apnoea necessitating artificial ventilation.

Dextromethorphan and codeine: comparison of plasma kinetics and antitussive effects.

Plasma kinetics of dextromethorphan (as dextrorphan ) and codeine were investigated after acute oral doses in 8 patients with pathological cough; after which the patients participated in an acute dose-response study of the antitussive effects of each drug administered as syrups. Maximum plasma codeine concentrations averaged 384 ng.ml-1 (s.d. +/- 78.3) occurring between 0.75 and 2h after ingestion of 60 mg codeine phosphate; in comparison mean peak plasma dextrorphan levels were 386 ng.ml-1 (s.d. +/- 107.2) and 388 ng.ml-1 (s.d. +/- 101.3) respectively, after administration of 60 mg dextromethorphan syrup and tablet formulations. Bioavailability of dextromethorphan tablets was comparable to syrup. No correlation emerged between instantaneous plasma concentrations of either dextrorphan or codeine and antitussive responses; however, peak antitussive effect was significantly related to log dose with both drugs. Antitussive effects of 30 mg codeine phosphate and 60 mg dextromethorphan hydrobromide did not differ significantly; both were superior to 30 mg dextromethorphan hydrobromide and placebo.

Ventricular fibrillation following high potency intravenous vitamin injection.

A 67-year-old woman developed ventricular fibrillation following Parenterovite injection. Subsequent post-mortem revealed normal coronary arteries. It is postulated that the high potency vitamin injection caused the arrhythmia.

Endometrial factors under treatment with oestrogen and oestrogen/progestogen combinations.

In a continuing prospective study, uterine curettage was undertaken on sixty-four patients attending a Menopause Clinic prior to consideration of gonadal hormone therapy. Two of these patients (3.1%) were found to have endometrial hyperplasia, and subsequently they were not given gonadal hormone therapy. Sixty-two patients with normal endometrium at pre-treatment curettage received cyclical oestrogen regimens or sequential oestrogen/progestogen treatments. Four (30.8%) of the thirteen patients in receipt of cyclical 'high-dose' oestrogens developed cystic glandular hyperplasia, whereas none of the patients taking either cyclical 'low-dose' oestrogens (thirty patients) or cyclical-sequential oestrogen/progestogen regimens (nineteen patients) developed endometrial hyperplasia. Among the patients with a normal endometrium, both before and during cyclical gonadal hormone therapy, regular withdrawal bleeding was experienced by thirty-two patients (51.6%). Breakthrough bleeding occurred in nine (14.5%), while twenty-one patients (33.9%) had no vaginal bleeding. Of the four patients with normal endometrium at pre-treatment curettage who subsequently developed endometrial hyperplasia during cyclical 'high-dose' oestrogen therapy, regular withdrawal bleeding was experienced by two patients, and in one of these breakthrough bleeding also occurred. Furthermore, in the four patients who developed endometrial hyperplasia, this condition occurred within six months in two patients and within 9 and 10 months respectively in the remaining two. In the nineteen patients receiving cyclical sequential oestrogen/progestogen regimens, all had regular withdrawal bleeding, while one patient had breakthrough bleeding during sequential therapy. It is concluded that in those climacteric patients who present with severe menopausal symptoms which necessitate the administration of high-dose oestrogen regimes it is necessary either to undertake both pretreatment uterine curettage or to add a progestogen to the oestrogen in a sequential regimen.

Clinical therapeutic evaluation of methylcysteine hydrochloride in patients with chronic obstructive bronchitis: a balanced double-blind trial with placebo control.

A double-blind, between-patient, placebo controlled trial was carried out to investigate the effects of methylcysteine hydrochloride in patients with chronic obstructive bronchitis. After a 2-week washout period on placebo, 30 patients were allocated at random to treatment for 6 weeks with either methylcysteine (1200 mg daily in Week 1, 800 mg daily in Week 2, then 600 mg daily) or with identical placebo tablets on the same regimen. During the post-treatment period, all patients returned to a single-blind placebo regimen (6 tablets daily) for a further 14 days. Assessments were made at the start, at regular intervals during the trial, and at the end of the post-treatment period, of subjective and objective measures of clinical response, and measurements of pulmonary function and certain physico-chemical properties of sputum. The results showed that methylcysteine increased sputum volume, reduced the viscidity of sputum, and significantly improved the subjective assessments of ease of expectoration and severity and frequency of cough, leading to a definite improvement in the patients' clinical state. No side-effects of clinical significance were reported and no abnormalities were found in any of the haematological, hepatic and renal function tests carried out.
