- Retention of intravenously or orally administered 47Ca in the human body are described by a two-parameter function. It is then sufficient to make only a few whole-body measurements to determine the retention function, avoiding faeces sampling and stool markers. Seven days after intake the non-absorbed calcium was excreted and the model agreed with the measured relative retention. Absorption of calcium could then, in some cases (e.g. comparative studies), be described by relative retention at the 7th day after intake. Copyright (C) 2000 Elsevier Science Ltd.

- Background: Pre-hospital delay in myocardial infarction (MI) patients' is of great concern. The total ischemic time, i.e., between symptom onset and reperfusion therapy is the most important factor to achieve best possible outcome. One reason for patient delay is choice of first medical Contact (FMC), still not everyone contact the emergency medical services. A previous Swedish cross-sectional multicentre study found that every fifth patient with an evolving ST elevated MI (STEMI) contacted an advisement tele-nurse intended for non-life-threatening situations as FMC. This caused a median difference in delay of 38 min from symptom onset to diagnosis. Advisement tele-nursing is an expanding actor in the Swedish healthcare system, as in some other Western nations.Purpose: The aim was to explore the communication between tele-nurses and callers when MI patients called a national health advisement number as FMC.Method: This study had a qualitative approach. We received access to 30 authentic calls. The recordings lasted between 0:39 minutes to 16:44 minutes, transcribed verbatim and analysed with content analysis. The following questions were applied to the transcript: (1) How do the callers communicate their symptom and context (2) How do the tele-nurses respond and which level of care was directed (3) Do the callers get an advice and what action do they take.Result: One third of the callers were female, aged 46–89 years, six were diagnosed with NSTEMI and 24 with STEMI. All tele-nurses were females. The calls followed a structure of three phases, opening-, orienting- and end-phase. The first phase was non-interfered, where the caller communicated their context and/or symptoms and tele-nurses adopt an active listening position, followed by two interactive phases. Four categories defined the interaction in the communication, indecisive, irrational, distinct or reasoning. The different interactions illustrated how tele-nurses and callers assessed and elaborated upon symptom, context and furthermore expressed the process in the dialogue. Type of interaction was pivotal for progress in the call and had impact on the communicative process either sufficient in reaching a mutual understanding or not. An indecisive or irrational interaction could increase risk of acute care not being recommended. A non explicit explanation, why it is of importance to seek acute care could lead caller to ignore the advice.Conclusion: Both communicative and medical skills are needed to identify level of urgency. Our study suggests that the interaction in the communication categorised in four types, indecisive, irrational or distinct or reasoning can mislead level of care directed as well as a disability to express the need of acute care. This knowledge adds new perspective and hopefully will our findings be useful to deepen our knowledge in identifying MI patients and in a broader sense improve educational efforts and diminsh delay.

- Summary Background Disperse dyes (DDs) are the most common sensitizers among textile dyes, but there is little knowledge of the clinical relevance of positive patch test reactions. Objective To investigate if patient-reported textile-related skin problems can be explained by contact allergy to eight different DDs and/or to chemically related substances, by occupation or by atopic constitution, and if the skin problems are influenced by age or sex. Methods A questionnaire on textile-related skin problems was answered by 858 of 982 consecutively patch tested patients in Malmö, Sweden and in Leuven, Belgium. The baseline series used for patch testing was supplemented with a textile dye mix (TDM) consisting of the eight DDs and with the separate dyes. The association between textile-related skin problems and contact allergy to the DDs and other risk factors was investigated using multiple logistic regression analysis. Results Eighteen per cent of the patients suspected textiles as a cause of their skin problems. Atopic constitution and female sex were risk factors for skin reactions. Synthetic materials were the most common textiles to give skin problems. A significant association was found between self-reported textile-related skin problems and contact allergy to para-phenylenediamine (PPD) [adjusted odds ratio (OR) 2.1; 95% confidence interval (CI) 1.0-4.3]. A similar, but more imprecise, adjusted OR was found for TDM (OR 1.9; 95% CI 0.57-5.6). Contact allergy to black rubber mix was too rare to be evaluated. Conclusions Contact allergy to PPD was a more prevalent indicator for skin reactions to textiles than the TDM used in this study.

- Background: Patients with hand eczema often describe symptoms such as pain, clumsiness and difficulty flexing their fingers, thus impairing the function of the hand. Objective: The aim of this study was to investigate whether hand eczema is associated with a measurable impairment of hand strength and dexterity. We also studied the relationship between hand function and the ability to perform activities of daily living (ADL), pain level and quality of life measured with the Dermatology Life Quality Index (DLQI). Methods: Twenty-one participants with ongoing hand eczema were examined with well-established methods for measuring hand grip strength, pinch strength and dexterity. A questionnaire was designed to investigate perceived ability to perform ADL. The participants were also asked to grade their current pain level, and the DLQI was used to assess the participants' quality of life. A group of 12 participants was reinvestigated when healed. Results: The participants demonstrated a significant improvement in all functional tests when healed. There was a strong correlation between ADL and both dexterity and hand grip strength. There was also a strong correlation between ADL and pain. All participants reported some difficulty performing ADL. Conclusions: Our results suggest that ongoing hand eczema may lead to a measurable decrease of strength and dexterity of the hand, leading to an impairment of the ability to perform ADL and consequently to a poorer quality of life.
