- PURPOSE: To evaluate a program initiated in 1987 by the Swedish Melanoma Study Group aiming to provide preventive surveillance to kindreds with hereditary cutaneous melanoma and dysplastic nevus syndrome. PATIENTS AND METHODS: Overall, 2,080 individuals belonging to 280 melanoma families were followed for 14 years between 1987 and 2001 at 12 participating centers. Data were registered in a central database. RESULTS: Among 1,912 skin lesions excised during follow-up, 41 melanomas were removed in 32 individuals. Of these, 15 (37%) were in situ melanomas and 26 (63%) invasive melanomas. The median tumor thickness of invasive melanomas was 0.5 mm. Ulceration was absent in 24 of 26 invasive melanomas (92%) and 12 (46%) lacked vertical growth phase. Compared with melanomas in the general Swedish population, the melanomas identified in these kindreds during follow-up had better prognostic characteristics. All melanomas except one were diagnosed in families with two or more first-degree relatives with melanoma. Diagnosis of melanoma occurred in three of eight kindreds with germline CDKN2A mutations, supporting that families with such mutations are at increased risk for melanoma development. Of the 32 individuals who developed melanoma during follow-up, 21 (66%) had had at least one previously diagnosed melanoma. CONCLUSION: This study shows that a coordinated program aimed at detecting and offering skin surveillance in kindreds with hereditary cutaneous melanoma results in a low incidence of melanomas during the follow-up period and that the tumors that do arise have favorable prognostic characteristics.

A new combined multicompartmental model for apolipoprotein B-100 and triglyceride metabolism in VLDL subfractions

- The use of stable isotopes in conjunction with compartmental modeling analysis has greatly facilitated studies of the metabolism of the apolipoprotein B (apoB)-containing lipoproteins in humans. The aim of this study was to develop a multicompartment model that allows us to simultaneously determine the kinetics of apoB and triglyceride (TG) in VLDL(1) and VLDL(2) after a bolus injection of [(2)H(3)]leucine and [(2)H(5)]glycerol and to follow the catabolism and transfer of the lipoprotein particles. Here, we describe the model and present the results of its application in a fasting steady-state situation in 17 subjects with lipid values representative of a Western population. Analysis of the correlations showed that plasma TG was determined by the VLDL(1) and VLDL(2) apoB and TG fractional catabolic rate. Furthermore, the model showed a linear correlation between VLDL(1) TG and apoB production. A novel observation was that VLDL TG entered the circulation within 21 min after its synthesis, whereas VLDL apoB entered the circulation after 33 min. These observations are consistent with a sequential assembly model of VLDL and suggest that the TG is added to a primordial apoB-containing particle in the liver.

Guidelines on the use of photodynamic therapy for nonmelanoma skin cancer: an international consensus. International Society for Photodynamic Therapy in Dermatology, 2005

- Topical photodynamic therapy (PDT) is used to treat nonmelanoma skin cancers, such as actinic keratoses, Bowen's disease, and basal cell carcinoma (superficial and nodular). This article presents up-to-date, practical, evidence-based recommendations on the use of topical PDT using 5-aminolevulinic acid or methyl aminolevulinate for the treatment (and prevention) of nonmelanoma skin cancers. A systematic literature review was conducted (using MEDLINE), and recommendations were made on the basis of the quality of evidence for efficacy, safety/tolerability, cosmetic outcome, and patient satisfaction/preference. Topical PDT is highly effective in the treatment of actinic keratoses, Bowen's disease, superficial and thin nodular basal cell carcinomas, with cosmesis typically superior to that achieved with existing standard therapies. PDT may also be a means of preventing certain nonmelanoma skin cancers in immunosuppressed patients.

Percutaneous absorption of the sunscreen benzophenone-3 after repeated whole-body applications, with and without ultraviolet irradiation
- 2006

- BACKGROUND: Benzophenone-3 (BZ-3; 2-hydroxy-4-methoxybenzophenone, oxybenzone) is commonly used to absorb ultraviolet (UV) radiation. BZ-3 penetrates the skin and can be found in the urine. The amount varies between 0.4% and 2%. This seems to be the main metabolic pathway in rats. OBJECTIVES: To investigate the total amount of BZ-3 excreted in the urine after repeated topical whole-body applications of a sunscreen and to see if UV radiation has any effect on the amount excreted. METHODS: Twenty-five volunteers applied a commercially available sunscreen containing 4% BZ-3 morning and night for 5 days. Their urine was measured during those 5 days and during a further 5 days after the last application. They were divided into groups A (unirradiated) and B. Group B received UV radiation according to skin type: UVA between 400 and 707 J cm(-2), and UVB between 0.46 and 2.0 J cm(-2). BZ-3 in urine was analysed with a high-performance liquid chromatography method. RESULTS: The volunteers excreted 1.2-8.7% (mean 3.7%) of the total amount of BZ-3 applied. There was no significant difference between the two groups (P < 0.99, t-test). CONCLUSIONS: We show that a large amount of BZ-3 is absorbed. BZ-3 is accumulated in the body as the volunteers excreted BZ-3 5 days after the last application.

Photostability of commercial sunscreens upon sun exposure and irradiation by ultraviolet lamps
- 2007

Ingår i: BMC Dermatol. - 1471-5945. ; 7

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Sunscreens are being widely used to reduce exposure to harmful ultraviolet (UV) radiation. The fact that some sunscreens are photounstable has been known for many years. Since the UV-absorbing ingredients of sunscreens may be photounstable, especially in the long wavelength region, it is of great interest to determine their degradation during exposure to UV radiation. Our aim was to investigate the photostability of seven commercial sunscreen products after natural UV exposure (UVnat) and artificial UV exposure (UVart). METHODS: Seven commercial sunscreens were studied with absorption spectroscopy. Sunscreen product, 0.5 mg/cm2, was placed between plates of silica. The area under the curve (AUC) in the spectrum was calculated for UVA (320-400 nm), UVA1 (340-400 nm), UVA2 (320-340 nm) and UVB (290-320 nm) before (AUCbefore) and after (AUCafter) UVart (980 kJ/m2 UVA and 12 kJ/m2 of UVB) and before and after UVnat. If theAUC Index (AUCI), defined as AUCI = AUCafter/AUCbefore, was > 0.80, the sunscreen was considered photostable. RESULTS: Three sunscreens were unstable after 90 min of UVnat; in the UVA range the AUCI was between 0.41 and 0.76. In the UVB range one of these sunscreens was unstable with an AUCI of 0.75 after 90 min. Three sunscreens were photostable after 120 min of UVnat; in the UVA range the AUCI was between 0.85 and 0.99 and in the UVB range between 0.92 and 1.0. One sunscreen showed in the UVA range an AUCI of 0.87 after UVnat but an AUCI of 0.72 after UVart. Five of the sunscreens were stable in the UVB region. CONCLUSION: The present study shows that several sunscreens are photounstable in the UVA range after UVnat and UVart. There is a need for a standardized method to measure photostability, and the photostability should be marked on the sunscreen product.

The hatching larva of the priapulid worm Halicryptus spinulosus

Tidskriftsartikel (refereegranskat)abstract
- Despite their increasing evolutionary importance, basic knowledge about the priapulid worms remains limited. In particular, priapulid development has only been partially documented. Following previous description of hatching and the earliest larval stages of Priapulus caudatus, we here describe the hatching larva of Halicryptus spinulosus. Comparison of the P. caudatus and the H. spinulosus hatching larvae allows us to attempt to reconstruct the ground pattern of priapulid development. These findings may further help unravelling the phylogenetic position of the Priapulida within the Scalidophora and hence contribute to the elucidation of the nature of the ecdysozoan ancestor.
