RESUMEN

AIM: Investigation of the compatibility of work and family life for physicians in the Munich metropolitan area. METHODS: Survey of a representative sample of 1,800 physicians using a questionnaire. RESULTS: Men were less satisfied (7% very satisfied vs. 21%) with compatibility between work and family life than women. The group least satisfied overall was hospital-based physicians (p=0.000, chi-square=122.75). Women rather than men cut back their career due to children, perceived their professional advancement as impaired, desisted from establishing private practice or quit hospital employment altogether. Respondents strove for flexible childcare and makeshift solution if the established service failed. Most did not have that at their disposal. Hospital-based physicians wished for predictable working hours, and would like to have a say in the structure of their schedule. For the majority this was not the case. While for 80% it would be important to participate in the definition of their working hours, this was only possible in 17%. 86% found the opportunity to work part-time important, but many doctors (more than 30%) did not have that option. The biggest help for office-based physicians would be an expedited procedure by the Bavarian Association of Statutory Health Insurance Physicians (KVB) when applying for a proxy. The second most important would be the ability to hand over on-call duties. 36% of respondents felt that compatibility of work and family life was best achieved outside of patient care, during residency 42% believed this to be the case. Only 6% of physicians felt the best compatibility to be achieved in a hospital. Among the physician owners of practices, 34% considered their model to be the best way to reconcile both aspects of life. CONCLUSION: More flexible options for childcare and more influence on the definition of working hours are necessary in order to better reconcile work and family life. For office-based physicians it must be made easier to find a substitute. Currently, especially women consider children as hindering their careers. Hospitals are perceived as extremely unfavorable workplaces for achieving compatibility between work and family life.

RESUMEN

Although topical antifungal therapies for treating onychomycosis are available, the cure rate is unsatisfactorily low with a simultaneously high risk of recurrence. One reason might be the formation of dormant fungal cells by the pathogen, known as spores, which can survive in the affected nail keratin, thereby evading the effect of antifungal drugs. In this in vitro study, the ability of amorolfine and four other antimycotics (ciclopirox, bifonazole, terbinafine and fluconazole) to kill microconidia of the dermatophyte Trichophyton rubrum, chlamydospores of the dermatophyte Epidermophyton floccosum and blastospores of the yeast Candida albicans was extensively studied as these fungi occur predominantly in onychomycosis. The effectiveness of all five antimycotics depended on the drug concentration and the incubation time: a concentration of 10-1000 times the minimum inhibitory concentration against growing hyphae cells is needed to exert a sporicidal action. Amorolfine and ciclopirox showed the same sporicidal efficacy and kinetics for all three varieties of spores. Both were more effective than fluconazole and bifonazole against microconidia and chlamydospores as well as slightly more potent against chlamydospores and blastospores than terbinafine after 4 days of incubation and at concentrations of ≥10 µg ml(-1). Finally, sporicidal activity on the tested strains was demonstrated for all five different antimycotics used for onychomycosis treatment.

RESUMEN

The expansive use of immunosuppressive medications in fields such as transplantational medicine and oncology, the higher frequency of invasive procedures in an ageing population and the HIV/AIDS pandemic have increased the frequency of systemic fungal infections. At the same time, increased resistance of pathogenic fungi to classical antifungal agents has led to sustained research efforts targeting alternative antifungal strategies. In this review, we focus on two promising approaches: cationic peptides and the targeting of fungal virulence factors. Cationic peptides are small, predominantly positively charged protein fragments that exert direct and indirect antifungal activities, one mechanism of action being the permeabilization of the fungal membrane. They include lysozyme, defensins and cathelicidins as well as novel synthetic peptides. Among fungal virulence factors, the targeting of candidal secreted aspartic proteinases seems to be a particularly promising approach.

RESUMEN

Identification of dermatophytes is usually based on morphological characteristics determined by time-consuming microscopic and cultural examinations. An effective PCR-ELISA method has been developed for rapid detection of dermatophyte species directly from clinical specimens within 24 h. Isolated genomic DNA of skin scrapings and nail samples from patients with suspected dermatophyte infections is amplified with species-specific digoxigenin-labelled primers targeting the topoisomerase II gene. The subsequent ELISA procedure with biotin-labelled probes allows a sensitive and specific identification of the five common dermatophytes -Trichophyton rubrum, T. interdigitale, T. violaceum, Microsporum canis and Epidermophyton floccosum. PCR-ELISA, based on the new polyphasic species concept, was assessed using 204 microscopy-positive samples in two university mycological laboratories in Munich and Tübingen, and 316 consecutive specimens - regardless of mycological findings - in a dermatological practice laboratory in Neu-Ulm. One of the five dermatophytes was confirmed by PCR-ELISA in 163 of 204 (79.9%) of the clinical samples from the university hospitals found positive using microscopy. Culture was positive for dermatophytes in 59.8% of the same cases. A significant difference between these two methods could be demonstrated using the McNemar test (P < 0.005). Analysis of specimens from Neu-Ulm confirmed the results in a dermatological practice laboratory as 25.0% of the specimens had positive PCR results, whereas only 7.3% were positive according to culture. Direct DNA isolation from clinical specimens and the PCR-ELISA method employed in this study provide a rapid, reproducible and sensitive tool for detection and discrimination of five major dermatophytes at species level, independent of morphological and biochemical characteristics.

RESUMEN

BACKGROUND: About 30-50 % of rosacea patients have ocular involvement. The symptoms range from a foreign-body sensation to conjunctivitis or blepharitis and may even include severe corneal ulcerations. Systemic treatment is generally with tetracycline. Side effects can occur with the usual antimicrobial dose. PATIENTS AND METHODS: In a retrospective study, seven patients were evaluated who had been treated for ocular rosacea with a sub-antimicrobial dose of doxycycline 40 mg in a slow-release form (Oraycea). The responses were evaluated on the basis of clinical findings. RESULTS: Seven patients with an average age of 63 took slow release doxycycline 40 mg every day for at least two months. In five patients, other systemic drugs had already failed. All patients experienced a clear improvement in their ocular rosacea after an average of 2.29 months of treatment. One patient had complete clearance and another had almost complete clearance. None of the patients experienced side effects. CONCLUSIONS: A sub-antimicrobial dose of slow release doxycycline 40 mg daily is an effective long-term therapy for ocular rosacea. It is not associated with the side effects of long-term antibiotic therapy or the risk of resistance.

RESUMEN

INTRODUCTION: Daily parallel application of adapalene and nadifloxacin has been determined to be effective and well tolerated in patients with acne vulgaris in randomized, controlled clinical studies. Here, the authors report the results from a large, prospective, uncontrolled, multicentric, noninterventional study under real-life conditions in Germany. The effect of treatment on acne severity, safety, and, for the first time, health-related quality of life (HRQoL) was investigated. METHODS: Of the 292 patients (safety collective: 231 adults, 61 adolescents) who had at least grade 4 acne vulgaris on the face as per the Leeds Revised Acne Grading (LRAG), 273 (efficacy collective: 213 adults, 60 adolescents) were treated with adapalene 0.1% cream or gel and nadifloxacin 1% cream for the defined minimum of 28 days. Patients were evaluated for acne severity, acne-related facial symptoms, HRQoL, overall assessment of therapy, and safety. RESULTS: After the median treatment duration of 37 and 38 days (adults and adolescents, respectively), 93.4% and 85.0% of adults and adolescents, respectively, exhibited a sustained decrease in acne severity. The LRAG decreased by at least 3 scores in 29.1% and 24.6% of female and male adults, respectively. HRQoL improved in 67.9% and 63.5% of adults and adolescents, respectively (median improvement in the Dermatology Life Quality Index scores per patient of 3.0 [female adults], 1.0 [male adults], and 2.0 for all adolescents in the Children's Dermatology Life Quality Index). Female adults were more impaired in terms of HRQoL compared to male adults. The 2 best overall efficacy ratings were provided by physicians in 79.3% and 69.5% and by patients in 68.5% and 58.3% of adult and adolescent cases, respectively. The treatment was well tolerated, as reflected in the low number of 9 mild adverse events (AEs), all of which resolved without treatment. However, 4 patients terminated the study prematurely due to AEs. CONCLUSION: In this study, the parallel use of adapalene and nadifloxacin for at least 5 weeks resulted in a rapid improvement in acne severity, an increase in HRQoL, and a good safety profile. Therefore, it represents a promising treatment option that offers the possibility of flexible therapy adjustment.

RESUMEN

Sertaconazole nitrate is a broad-spectrum antifungal agent indicated in the United States for the treatment of tinea pedis interdigitalis. The objective of this subgroup analysis was to evaluate the safety and efficacy of sertaconazole nitrate cream 2%, specifically in participants with tinea pedis interdigitalis (ie, fungal skin disease of the toe web) of dermatophyte origin. A total of 92 participants were included in this analysis. The primary end points were eradication of the pathogen (confirmed by fungal culture results) and reduction in total clinical score (TCS) of at least 2 points. Secondary end points included reducing signs and symptoms and reporting adverse events (AEs). After 4 weeks of treatment, 88.8% (79/89) of evaluable participants achieved success on the primary end points. Most participants also demonstrated substantial improvement in signs and symptoms after 4 weeks of treatment: 63.7% (58/91) were free of erythema, 33.0% (30/91) were free of desquamation, and 91.2% (83/91) were free of itch. The rate of reported AEs was low (8.7% [8/92]), and none were considered serious. These findings indicate that sertaconazole nitrate cream 2% is highly safe and effective in the treatment of tinea pedis interdigitalis.

RESUMEN

Discussing aesthetic issues and their management with patients is a growing area of dermatologic practice. Sometimes treatment options within one's own discipline are rapidly discussed, without a clear idea of the various aspects of the face which all combine to produce beauty and attractiveness. We review various features leading to the impression of beauty and attractiveness. Familiarity with these concepts should facilitate a broader discussion with the patient on the aspects of beauty and attractiveness beyond the borders of one's own discipline and also lead to multidisciplinary treatment options. We also examine the question how much the personality of the beholder himself is involved in the perception of attractiveness and beauty (of the person sitting opposite to him). The "ideal" face has an average profile with slightly protrusive and full lips. Attractiveness increases with average features and symmetry. Moreover, particular features such as the scheme of childlike characteristics combined with aspects of maturity and expression make a female face appear especially beautiful. Which attributes contribute to attractiveness of a man's face are controversial. Clear male signals such as a strong chin are likely not to increase attractiveness.

RESUMEN

To optimize the treatment of acne in Germany, the German Society of Dermatology (DDG) and the Association of German Dermatologists (BVDD) initiated a project to develop consensus-based guidelines for the management of acne. The Acne Guidelines focus on induction therapy, maintenance therapy and treatment of post-acne scarring. They include an evaluation of the most commonly used therapeutic options in Germany. In addition, they offer detailed information on how to administer the various treatments and on contraindications, adverse drug reactions, and drug interactions, taking into account gender and special conditions such as pregnancy and lactation. The Acne Guidelines were developed following the recommendations of the Association of Scientific Medical Societies in Germany (AWMF). The treatment recommendations were developed by an expert group and finalized by an interdisciplinary consensus conference. The first choice treatments for acute acne according to acne type are as follows: 1) comedonal acne: topical retinoids; 2) mild papular/pustular acne: fixed or sequential combinations of BPO and topical retinoids or of BPO and topical antibiotics; 3) moderate papular/pustular acne: oral antibiotic plus BPO or plus topical retinoid, or in a fixed combination 4) acne papulo-pustulosa nodosa and acne conglobata: oral antibiotic plus topical retinoid plus BPO or oral isotretinoin. For maintenance treatment: topical retinoid or its combination with BPO. Particular attention should be paid to compliance and quality of life. Additional treatment options are discussed in the main body of the text.

RESUMEN

BACKGROUND: In Roman medicine, face packs, plasters, unguents, and peelings were part of the therapy of dermatological diseases, but also served cosmetic purposes. Ancient medical textbooks inform us about the ingredients for these applications. Beyond medical literature, other genres contain information about dermatological applications. The Roman poet Ovid (43 BC-17 AD) wrote a didactic poem recording five recipes for topical applications for female faces (Medicamina faciei femineae). Researchers debate the relation of Ovid's poem to Roman medicine: Does the poem contain therapeutical or cosmetical information, or is it mere belles lettres? AIMS: The objective of the paper is to conduct a medico-historical classification of Ovid's poem by determining whether the ingredients of Ovid's recipes were thought to be effective by the authors of Roman medical textbooks. METHODS: First, translation and identification of the ingredients were carried out. Second, comparison of the ingredients' functions regarding the therapy of dermatological diseases in two important Roman medical textbooks was realized. For this purpose, several commentaries on the text of Ovid were used and a keyword search in Roman medical textbooks was performed. RESULTS: Ovid's five recipes contain 23 ingredients. All ingredients can be found in medical textbooks. We find that 14 of these ingredients serve cosmetic purposes, 17 serve the therapy of dermatological diseases, and 13 serve both. CONCLUSION: Ovid's recipes contain drugs that were considered effective by the authors of Roman medical textbooks. These drugs were recommended both for therapeutic and cosmetic purposes by the same authors. Therefore, Ovid's didactic poem is not mere belles lettres, but contains serious medical and cosmetical information. As far as we know, it is the first Roman text that contains dermatological recipes.

RESUMEN

Antimycotic nail lacquers are effective and safe for the treatment of onychomycosis. To assess the efficacy of three topical agents we studied the minimum inhibitory and fungicidal concentration of amorolfine, bifonazole and ciclopiroxolamine. Amorolfine showed the most effective fungistatic and fungicidal activity in vitro against seven clinical Trichophyton rubrum nail isolates, followed in descending order by ciclopiroxolamine and bifonazole. To mimic a nail infection more appropriately, the nail minimum fungicidal concentration (Nail-MFC) was determined in an onychomycosis model. Amorolfine and ciclopiroxolamine had Nail-MFCs ranging from 2-32 microg/ml and 16-32 microg/ml, respectively. In contrast, bifonazole was unable to kill T. rubrum in this model. Statistical analyses of the results show a significant difference between the two treatments with amorolfine and ciclopiroxolamine (P<0.001). For amorolfine a mean concentration of 12.28 microg/ml (95%-CI=[8.66, 17.41]) was sufficient to kill all strains, while for ciclopiroxolamine about twice that concentration was needed, i.e., 24.13 microg/ml (95%-CI=[17.06, 34.13]). The individual sensitivity of six of the seven T. rubrum strains was higher for amorolfine. These data demonstrate that both amorolfine and ciclopiroxolamine effectively kill T. rubrum growing on nail powder and suggest a better cidal action for amorolfine. Further investigation would be required to determine if these in vitro data can partially explain the clinical observation of significantly higher cure rates in onychomycosis following a therapy with an amorolfine-containing nail lacquer formulation.

RESUMEN

Proteolytic activity is an important virulence factor for Candida albicans (C. albicans). It is attributed to the family of the secreted aspartic proteinases (Saps) from C. albicans with a minimum of 10 members. Saps show controlled expression and regulation for the individual stages of the infection process. Distinct isoenzymes can be responsible for adherence and tissue damage of local infections, while others cause systemic diseases. Earlier, only the structures of Sap2 and Sap3 were known. In our research, we have now succeeded in solving the X-ray crystal structures of the apoenzyme of Sap1 and Sap5 in complex with pepstatin A at 2.05 and 2.5 A resolution, respectively. With the structure of Sap1, we have completed the set of structures of isoenzyme subgroup Sap1-3. Of subgroup Sap4-6, the structure of the enzyme Sap5 is the first structure that has been described up to now. This facilitates comparison of structural details as well as inhibitor binding modes among the different subgroup members. Structural analysis reveals a highly conserved overall secondary structure of Sap1-3 and Sap5. However, Sap5 clearly differs from Sap1-3 by its electrostatic overall charge as well as through structural conformation of its entrance to the active site cleft. Design of inhibitors specific for Sap5 should concentrate on the S4 and S3 pockets, which significantly differ from Sap1-3 in size and electrostatic charge. Both Sap1 and Sap5 seem to play a major part in superficial Candida infections. Determination of the isoenzymes' structures can contribute to the development of new Sap-specific inhibitors for the treatment of superficial infections with a structure-based drug design program.

RESUMEN

The family of secreted aspartic proteinases (Sap) encoded by 10 SAP genes is an important virulence factor during Candida albicans (C. albicans) infections. Antagonists to Saps could be envisioned to help prevent or treat candidosis in immunocompromised patients. The knowledge of several Sap structures is crucial for inhibitor design; only the structure of Sap2 is known. We report the 1.9 and 2.2 A resolution X-ray crystal structures of Sap3 in a stable complex with pepstatin A and in the absence of an inhibitor, shedding further light on the enzyme inhibitor binding. Inhibitor binding causes active site closure by the movement of a flap segment. Comparison of the structures of Sap3 and Sap2 identifies elements responsible for the specificity of each isoenzyme.

RESUMEN

BACKGROUND: Based on the results of numerous preclinical and clinical studies, sertaconazole can be considered a safe and effective drug for the treatment of fungal skin infections. OBJECTIVE: The objective of the study was to compare the efficacy of a solution containing 2% sertaconazole with the well established 2% sertaconazole cream formulation in patients with tinea corporis, tinea pedis interdigitalis, or a corresponding candidosis. METHODS: This was a prospective, open-label, randomized, controlled, parallel-group, multicenter, noninferiority therapy study. Patients received either sertaconazole solution or cream twice daily for 28 days. The full analysis set comprised 160 patients in the solution group and 153 patients in the cream group. The primary efficacy parameter was a combination of culture test result and total clinical score. Efficacy was defined by eradication of the pathogen and reduction of the total clinical score between pretreatment and the final visit. RESULTS: Efficacy was documented in 90.6% of patients using the solution and 88.9% of those using the cream (full analysis set). No adverse events occurred. CONCLUSION: Solution and cream formulations of 2% sertaconazole applied for 28 days were associated with comparable efficacy and safety in the treatment of fungal skin infections.

RESUMEN

BACKGROUND: Photodynamic therapy (PDT) has been developed into a widely used method to treat actinic keratoses and basal cell carcinoma. OBJECTIVE The objective was to assess the efficacy of PDT in the treatment of actinic cheilitis of the lower lip. METHODS: In this prospective, uncontrolled study at a university dermatology department, 15 patients with actinic cheilitis received two sessions of PDT of the lower lip at an interval of 1 week using methylaminoxopentanoate and red light. Clinical and histopathologic evaluation was performed 3 months after therapy. RESULTS: Complete clinical cure was observed in 47% (7/15) and partial cure in another 47% (7/15) of the patients. By histopathologic analysis, residual disease was found in 62% (8/13). Cosmetic results and patients' satisfaction were good to excellent in most cases. Local pain was sufficiently controlled by local anesthesia. CONCLUSION: PDT can be an effective noninvasive method to treat actinic cheilitis of the lower lip.

RESUMEN

Cellulite or so called orange peel skin affects 80-90 % of all females. It is not considered as a pathological condition but as aesthetically disturbing dimpling of the skin seen most commonly on the thighs and buttocks. Despite its high prevalence, there have been only a few scientific investigations into the pathophysiology of cellulite reflected in the medical literature. A lack of knowledge regarding specific aetiopathogenetic factors and pathogenesis at large currently limits treatment options. The preferred hypotheses about the origin of cellulite include: gender specific dimorphic skin architecture, altered connective tissue septae, vascular changes and inflammatory processes. The most widely discussed management options include: attenuation of aggravating factors, physical procedures including laser therapy and application of topical incorporating actives. The latter approach has been evidence-based with respect to caffeine liposomal cream and retinol cream.

RESUMEN

The current investigation aimed to develop a valid specific field test to evaluate anaerobic physical performance in Aerobic Gymnastics athletes. We first designed the Specific Aerobic Gymnast Anaerobic Test (SAGAT), which included gymnastics-specific elements performed in maximal repeated sprint fashion, with a total duration of 80-90 s. In order to validate the SAGAT, three independent sub-studies were performed to evaluate the concurrent validity (Study I, n=8), the reliability (Study II, n=10) and the sensitivity (Study III, n=30) of the test in elite female athletes. In Study I, a positive correlation was shown between lower-body Wingate test and SAGAT performance (Mean power: p = 0.03, r = -0.69, CI: -0.94 to 0.03 and Peak power: p = 0.02, r = -0.72, CI: -0.95 to -0.04) and between upper-body Wingate test and SAGAT performance (Mean power: p = 0.03, r = -0.67, CI: -0.94 to 0.02 and Peak power: p = 0.03, r = -0.69, CI: -0.94 to 0.03). Additionally, plasma lactate was similarly increased in response to SAGAT (p = 0.002), lower-body Wingate Test (p = 0.021) and a simulated competition (p = 0.007). In Study II, no differences were found between the time to complete the SAGAT in repeated trials (p = 0.84; Cohen's d effect size = 0.09; ICC = 0.97, CI: 0.89 to 0.99; MDC95 = 0.12 s). Finally, in Study III the time to complete the SAGAT was significantly lower during the competition cycle when compared to the period before the preparatory cycle (p < 0.001), showing an improvement in SAGAT performance after a specific Aerobic Gymnastics training period. Taken together, these data have demonstrated that SAGAT is a specific, reliable and sensitive measurement of specific anaerobic performance in elite female Aerobic Gymnastics, presenting great potential to be largely applied in training settings.

RESUMEN

The transition of Candida albicans from a yeast to a hyphal form is controlled by several transcriptional factors, including the key regulators Cph1 and Efg1, and is considered an important virulence attribute. These factors, especially Efg1, regulate the expression of hyphal-associated genes e.g. SAP4-SAP6. In order to investigate the relevance of these transcriptional regulators for hyphal-independent SAP genes, recently constructed cph1 and efg1 single mutants and a cph1/efg1 double mutant lacking these factors were tested during interaction with oral epithelium and polymorphonuclear neutrophils. In contrast to the parental wild-type strain and the cph1 mutant, the efg1 and the cph1/efg1 mutants did not produce hyphal forms in all experiments and were less capable of damaging epithelial cells and neutrophil granulocytes. The attenuated epithelial lesions of these mutants were correlated not only with reduced expression of the hyphal-associated gene SAP4, but also with the lack of SAP1 and SAP3 expression previously shown to be important for oral infections. An efg1 mutant strain carrying a plasmid-borne copy of the EFG1 gene regained hyphal growth, damage of keratinocytes, granulocytes and the expression of SAP1 and SAP3. Although efg1 and cph1/efg1 mutants did not produce germ tubes during infection, expression of the hyphal-associated genes SAP5 and SAP6 was not completely abolished. A reduced capacity to stimulate an epithelial immune response manifested by a delayed onset of IL-1beta, IL-8 and TNF expression was only observed in the cph1/efg1-infected tissue. These results provide further evidence for a combined regulation of different virulence factors, such as dimorphism and expression of SAP genes. Furthermore, it could be demonstrated that the lack of Efg1 also caused reduced expression of hyphal-independent SAP genes. Both the EFG1 and the CPH1 gene products are necessary for adequate induction of an immune response.
