There is still an international need to develop broad-spectrum sunscreen products with an adequate UVB/UVA balance, while the approved filters available in the UVA are scarce. Currently, one of the few UVA filters approved in the United States and Europe is tert-butylmethoxydibenzoylmethane (BMDM, avobenzone). However, this compound is unstable from aphotochemical point of view and cannot be used in combination with certain sunscreens. In this paper, we investigate the photochemical behavior of a set of dibenzoylmethanes and chalcones. In particular, we carry out their absorption and emission spectra, evaluate their photochemical degradation, and study their generation of free radicals and singlet oxygen photoproduction. Two compounds resultedin having the basic properties of UVA filters (2′-hydroxy-4-methoxychalcone and 2′-hydroxy-4-methoxydibenzoylmethane). Further studies are proposed, such asformulating the compoundsinto emulsions or other commoncosmetic presentations, as well as combining them with broadly-used UVB filters. We have also considered the need to establish its toxicological profile.

Malignes Melanom − Früherkennung, Diagnostik und Nachsorge

Zusammenfassung

Hintergrund

Das maligne Melanom ist eine häufige Hautkrebsart mit einer sehr hohen Mortalität. In Europa versterben jährlich etwa 22.000 Menschen daran, davon etwa 2700 Patienten alleine in Deutschland. Die Inzidenz zeigt seit Jahren eine steigende Tendenz. Bedeutende Risikofaktoren für die Entstehung eines malignen Melanoms sind die Anzahl der melanozytären Nävi am Körper, eine positive Familienanamnese für Melanom und genetische Prädisposition.

Ziel

In dieser Arbeit soll auch dem Nichtdermatoonkologen eine Übersicht über die Diagnostik, Behandlung, Stadieneinteilung und Nachsorge des malignen Melanoms vermittelt werden.

Material und Methoden

Es wurde eine selektive Literaturrecherche in Medline über Pubmed erstellt und mit eigenen Erfahrungen der Autoren ergänzt.

Ergebnisse

Es werden 4 klinische Formen des Melanoms unterschieden: superfiziell spreitende Melanome (SSM), Lentigo-maligna-Melanome (LMM), akral-lentiginöse Melanome (ALM) und noduläre Melanome (NM). Diese unterscheiden sich sowohl in ihrem klinischen Erscheinungsbild, ihrer Lokalisation und Entwicklung und letztlich auch ihrer Prognose, die für das ALM und NM am ungünstigsten ist. Zur Diagnosesicherung und zur klinischen und pathologischen Stadieneinteilung ist eine operative Erstversorgung von kutanen Melanomen unerlässlich. Ab einer Tumordicke nach Breslow über 1 mm wird die diagnostische Exzision des Wächterlymphknotens (WLK) empfohlen. Bei Befall des WLK sollte zunächst eine Ausbreitungsdiagnostik mittels Schnittbildgebung erfolgen. Ist eine Exzision und Nachexzision und ggf. die WLK-Biopsie erfolgt, wird eine stadiengerechte Ausbreitungsdiagnostik empfohlen. Die empfohlene Nachsorge des malignen Melanoms gestaltet sich stadienadaptiert und entsprechend der aktuellen Leitlinie.

Comparative Post-operative Pain Analysis Between Coblator Assisted and Bipolar Diathermy Tonsillectomy in Paediatric Patients

Abstract

Tonsillectomy is one of the commonly performed otolaryngological operations. Despite a range of different techniques post-operative pain remains a major side-effect of this operation. Coblation assisted tonsillectomy is a latest technique of tonsillectomy. This technique is said to be associated with less intra-operative bleeding and less postoperative morbidity. We conducted a study in 100 patients to compare the pain scores between coblation assisted and bipolar diathermy tonsillectomy by FLACC score and Wong Baker scale score. The data so collected was statistically analysed using a t test and p values were calculated. The p value was highly significant (p < 0.001) for both scores in coblation assisted tonsillectomy 6 h postoperatively and on 1st postoperative day (p < 0.05). On 7th post-operative day however there was no significant difference in post-operative pain score using FLACC score in both groups but Wong baker scale scores were still significant. We concluded that post-operative pain was less with coblator assisted tonsillectomy as compared to bipolar diathermy tonsillectomy at least in early post-operative period.

Lymphedema following cancer therapy: overview and options

Abstract

This summit focusing on lymphedema following cancer therapy was held during the 7th International Symposium on Cancer Metastasis through the Lymphovascular System. It was unique for the inclusion of patients with lymphedema joining physicians, therapists, healthcare professionals, and researchers to highlight what is known and more importantly what is unknown about the current state of research and treatment in the United States. The session opened with an introduction to lymphedema and then explored the incidence of multiple cancer-related lymphedemas, imaging tools and techniques useful for the diagnosis of lymphatic system abnormalities, and the new findings concerning the genetics of cancer-related lymphedema. It closed with a review of advocacy for patients and healthcare professionals and both conservative and surgical treatment options, followed by a panel discussion and questions. The session provided important information and updates which will be of value for improving the rehabilitation and overall support of patients with cancer-related lymphedema.
