[Various scenarios for billing and remuneration of preoperative management of iron deficiency anemia in the German healthcare system]. / Verschiedene Szenarien zu Abrechnung und Kostenerstattung eines präoperativen Managements der Eisenmangelanämie im deutschen Gesundheitssystem.

More than 30% of all patients undergoing surgery suffer from preoperative anemia. Iron deficiency anemia is the most common type of anemia. The diagnostics and treatment of iron deficiency anemia can be carried out before patients undergo surgery as an alternative to blood transfusion and is an interdisciplinary task. This article gives an overview of various billing modalities and payment arrangements for management of preoperative anemia in the German healthcare system.

[Improvement of management of hypertension by implementation of alcohol screening and subsequent interventions in primary practice]. / Verbessertes Hypertonie-Management durch Alkohol-Screening und Folgeinterventionen in der Hausarztpraxis.

Hypertension and alcohol use are both part of the five most important risk factors for burden of disease in Western Europe, mainly because of their impact on non-communicable diseases (NCD). Both risk factors are prevalent with high overlap among patients in primary care. Implementation of a screening for alcohol among patients of hypertension in primary care followed by brief intervention for problem alcohol use or formal treatment for people with alcohol dependence could constitute an important step to reach the goals of the Global WHO Action Plan for Prevention and Control of NCD. In addition, such an intervention could improve the management of hypertension. In a working group of experts from clinical practice and research the rationale and potential barriers for this intervention were discussed and steps for implementation in primary care were developed.

Taste loss and recovery following radiation therapy.

Previous investigators have reported deficits in taste acuity in patients following radiation therapy for oropharyngeal cancer. In the present longitudinal study, 13 patients (mean age = 51.6 yrs) received conventional or hyperfractionated radiotherapy (63-76.8 Gy) for primary tumors of the oropharynx. One or both parotid glands and at least two-thirds of the tongue were included in the radiation field. Smell recognition and taste detection thresholds were determined at baseline, 1 month, 6 months, and 1 year post-radiation. Differences for smell recognition and the 4 taste qualities were assessed (independently) at the 4 time intervals, with a one-way ANOVA. Smell recognition was unaffected by radiation. There were significant elevations in thresholds for sweet (p < 0.005), salty (p < 0.005), bitter (p < 0.005), and sour (p< 0.001) during radiation therapy that were restored to baseline levels at 6 months and 1 year after radiation. This study demonstrated that radiation-induced taste deficits can be recovered by 6 months.

Salivary epidermal growth factor levels decrease in patients receiving radiation therapy to the head and neck.

OBJECTIVE: The objective of this study was to assess changes in salivary epidermal growth factor (EGF) in patients receiving radiation therapy to the head and neck and to determine whether salivary EGF levels correlate with the severity of radiation-induced oral mucositis. STUDY DESIGN: Thirteen patients and 18 control subjects were enrolled in the study. Saliva was collected before, during (weekly), and after radiation therapy. Salivary total protein (TP) and EGF concentrations were measured and correlated with the severity of oral mucositis. The variability in normalized EGF (ngEGF/mgTP) values and mucositis scores were analyzed with analysis of covariance, and the adjusted correlation coefficient was calculated. RESULTS: EGF levels decreased (P =.004), whereas TP levels increased over time (P =.039). A strong correlation was seen with decreasing normalized EGF values and more severe mucositis (P =. 0001). CONCLUSION: A strong negative correlation between normalized EGF and mucositis severity suggests a possible role for EGF in the progression of radiation-induced mucosal breakdown.

Comparison between saliva stimulants and a saliva substitute in patients with xerostomia and hyposalivation.

The purpose of this study was to assess patient preference and product efficacy of three non-prescription products for the symptomatic relief of xerostomia. The study group consisted of 80 individuals with a complaint of chronic (> six months) xerostomia and an unstimulated salivary flow rate of < 0.1 mL/min. The three products--a sorbitol/xylitol-sweetened chewing gum, a sorbitol-sweetened sour lemon lozenge, and a sorbitol/xylitol-sweetened artificial saliva substitute spray--were assigned in a permuted block randomization scheme. Each product was used for two weeks with an interval of one week between trials. The study did not identify any product to be statistically significant in terms of patient preference. Kruskal-Wallis testing revealed no statistical significance (P > 0.589) among the products. No product demonstrated marked efficacy in stimulating salivary output. ANOVA analysis followed by Tukey HSD testing revealed no significant difference between the baseline paraffin-stimulated mean flow rate and the gum- and lozenge-stimulated flow rates.

Myers-Briggs Type Indicator and dental school performance.

The Myers-Briggs Type Indicator (MBTI) was administered to 256 dental students, representing four classes, at the University of Florida College of Dentistry. The results of this psychological instrument were then correlated with overall dental school performance based on results from the National Dental Board Examinations Part I and II (NB-I, NB-II), yearly class rank, and specific academic difficulties as measured by the Student Performance Evaluation Committee. Introverted students were found to display a significantly increased performance on NB-I (p = .038) and NB-II (p = .044). They were also found, however, to demonstrate a progressively lower class rank over the four-year period than extroverted students and were more likely to experience major academic difficulties as well. Judging and sensing individuals were found to earn a higher class rank over the four-year period than perceiving and intuitive students, respectively. Perceiving students were found to exhibit major difficulties or were placed on probation more often than judging individuals. These results may prove useful in counseling students to recognize potential problems before they commence their dental education or to anticipate and address specific weaknesses during the course of their education.

The Cytobrush Plus cell collector in oral cytology.

The Cytobrush Plus cell collector (cytobrush) was compared with the wooden tongue depressor during oral exfoliative cytology. The degree of patient discomfort, the convenience to the clinician, and the quantity and distribution of epithelial cells collected were evaluated. Two-factor analysis of variance and parametric and nonparametric analyses were performed. Because of the favorable findings revealed in this study, we recommend that the cytobrush be considered for use when obtaining diagnostic cytologic smears from the oral mucosa.
