Psoriasis confined strictly to vitiligo areas – a Koebner‐like phenomenon?

Vitiligo and psoriasis are both common skin disorders. However, psoriasis strictly confined to pre-existing vitiligo areas is rare and suggests a causal relationship. We report here on two patients with a strict anatomical colocalization of vitiligo and psoriasis. The histopathological examinations showed typical changes for both diseases together with a dense infiltrate of CD4+ and CD8+ T cells. By immunohistochemistry, intracytoplasmatic granzyme B and tumour necrosis factor alpha (TNF-alpha) were detected within the T-cell population, suggesting the functional activity of these cells and the creation of a local T helper 1 (Th1)-cytokine milieu. Additionally, in one patient we could identify anti-melanocytic T cells by tetramer staining and enzyme-linked immunospot (ELISPOT) analysis. These skin-infiltrating lymphocytes might trigger, by the local production of Th-1 cytokines such as TNF-alpha and interferon-gamma (IFN-gamma), the eruption of psoriatic plaques in patients with a genetic predisposition for psoriasis.     

Aktualisierte Kurzfassung der Leitlinien zur Pr?vention, Diagnostik und Therapie der nosokomial erworbenen Pneumonie

Hintergrund:  

Die nosokomiale Pneumonie gehört zu den häufigsten nosokomialen Infektionen und ist die häufigste auf der Intensivstation. Die nosokomiale Pneumonie ist mit einer signifikanten Mortalität und Morbidität assoziiert, und ihr Auftreten verschlechtert die Prognose des Patienten deutlich. Nach der Definition der DRGs auch im deutschen Krankenhaussystem ist die nosokomiale Pneumonie überwiegend Sache des Krankenhauses und kann somit nicht nur das Ergebnis der Patientenbehandlung, sondern auch das finanzielle Ergebnis des Krankenhauses beeinträchtigen.     

Tubal manometry: the question of normal values, values in chronic mesotympanic purulent middle ear infections

We investigated tubal function by equalization manometry in 68 patients with unilateral traumatic perforation of the tympanic membrane, and in 116 patients with chronic mesotympanic suppuration (85 dry and 31 discharging ears). Our criterion of normal tubal function is the ability to equalize a difference in pressure of +/- 30 hPa by means of at most 7 swallowings. This result was achieved in only 25% of the dry perforations and in none of the patients with discharging ears. Normal tubal function may only be expected in 25% of patients with chronic otitis media.     

Intraoperative radiotherapy (IORT) is an option for patients with localized breast recurrences after previous external-beam radiotherapy

Background  

For patients suffering of recurrent breast cancer within the irradiated breast, generally mastectomy is recommended. The normal tissue tolerance does not permit a second full-dose course of radiotherapy to the entire breast after a second breast-conserving surgery (BCS). A novel option is to treat these patients with partial breast irradiation (PBI). This approach is based on the hypothesis that re-irradiation of a limited volume will be effective and result in an acceptable frequency of side effects. The following report presents a single center experience with intraoperative radiotherapy (IORT) during excision of recurrent breast cancer in the previously irradiated breast.     

The Family System Test (FAST)

The impact of a cancer diagnosis upon a family has become a focus of clinical interest, but few scientific studies have been completed in this area. The objectives of this pilot study were twofold: first, to test the applicability of the Family System Test (FAST) in families (n=5) with a young adult member with cancer and secondly to evaluate patterns of interactions within these families. Results show that the FAST is applicable and useful to evaluate the different perceptions of hierarchy and cohesion - two essential variables - within these families. The great majority of family members represented their relationships as balanced (i.e., cohesive and moderately hierarchical). However, contrary to nonclinical families, fathers had a less positive view than mothers and patients: fathers more often perceived family and parenteral relations as unbalanced, and also more often perceived a reversal of hierarchy and a cross-generational coalition within the family. Implications for future research and clinical care are discussed.     

Ischemic necrosis of the lunate. The value of nuclear spin tomography in comparison to conventional roentgen studies

Conventional radiographs do not always make it possible to confirm a diagnosis of ischemic necrosis of the lunate in the early stages of disease. For these doubtful cases MRI is justifiable in addition, to diagnose or to rule out ischemic necrosis of the lunate.
