[Eumycetoma due to Fusarium chlamydosporum : Case report und review of the literature]. / Eumyzetom durch Fusarium chlamydosporum : Fallbericht und Literaturübersicht.

Eumycetomas are chronic purulent infections by (mold) fungi that affect the skin and subcutaneous tissue and are associated with a granulomatous inflammatory reaction. An affection of deeper structures is possible and can lead to amputation. In most cases, the distal lower limbs are affected. The clinically similar actinomycetoma is caused by gram-positive, filamentous bacteria. Both diseases are subsumed as mycetomas and have been classified by the World Health Organization as "neglected tropical diseases". Eumycetomas are endemic in the "Trans-African Belt". Pathophysiologically, there is an inoculation of the respective, partially ubiquitous pathogens into the skin through microtrauma during barefoot walking. Characteristic criteria in histology are grains which correspond to microcolonies of the pathogen in vivo. In addition to culturing the pathogen, further molecular diagnostics should be pursued. Imaging procedures are usually necessary before major surgery. The treatment is difficult and lengthy and the use of systemic antifungals in combination with an operative approach is the first-line treatment. Itraconazole continues to be the gold standard. In refractory cases terbinafine can be used as a second-line therapy. Wearing sturdy footwear is an effective prophylaxis. Although preventable and treatable, eumycetoma, as a disease of the poor, remains endemic and is associated with considerable morbidity and socioeconomic burden. This is the first report on a eumycetoma in a patient from Sudan due to Fusarium chlamydosporum. Treatment with oral terbinafine for 1.5 years was successful.

A patient-centric approach to quality control and dosimetry in CT including CBCT.

One measurement and an algebraic formula are used to calculate the incident air kerma (Ka,i) at the skin after any CT examination, including cone-beam CT (CBCT) and multi-slice CT (MSCT). Empty scans were performed with X-ray CBCT systems (dental, C-arm and linac guidance scanners) as well as two MSCT scanners. The accumulated Ka,i at the flat panel (in CBCT) or the maximum incident air kerma at the isocentre (in MSCT) were measured using a solid-state probe. The average Ka,i(skin), at the skin of a hypothetical patient, was calculated using the proposed formula. Additional measurements of dose at the isocentre (DFOV) and kerma-area product (KAP), as well as Ka,i(skin) from thermoluminiscence dosimeters (TLDs) and size-specific dose estimates are presented for comparison. The Ka,i(skin) for the standard head size in the dental scanner, the C-arm (high dose head protocol) and the linac (head protocol) were respectively 3.33 ±â€¯0.19 mGy, 15.15 ±â€¯0.76 mGy and 3.23 ±â€¯0.16 mGy. For the first MSCT, the calculated Ka,i(skin) was 13.1 ±â€¯0.7 mGy and the TLDs provided a Ka,i(skin) between 10.3 ±â€¯1.1 mGy and 13.8 ±â€¯1.4 mGy. Estimation of patient air kerma in tomography with an uncertainty below 7% is thus feasible using an empty scan and conventional measurement tools. The provided equations and website can be applied to a standard size for the sake of quality control or to several sizes for the definition of diagnostic reference levels (DRLs). The obtained incident air kerma can be directly compared to the Ka,i from other X-ray modalities as recommended by ICRU and IAEA.

Pathogenesis and clinical presentation of rosacea as a key for a symptom-oriented therapy.

Rosacea is a common chronic inflammatory skin disorder that typically occurs in adults and affects the face. Synonyms of rosacea include "acne rosacea", "couperose" and "facial erythrosis", in German also "Kupferfinne" and "Rotfinne". The disorder is characterised by a chronic and flaring course and is caused by a genetically predisposed, multifactorial process. A higher incidence is seen in people with fair skin and a positive family history. The characteristic rosacea symptoms manifest primarily, but not exclusively centrofacially, with forehead, nose, chin and cheeks significantly affected. Based on the various main symptoms a classification of the individual clinical pictures can be performed. However, a classification often does not reflect the clinical reality, since the various symptoms commonly coexist. The present review provides an introduction on pathogenesis and clinical manifestations of rosacea and prefers a symptom-oriented therapy approach.

Rosazea-Management: Update über allgemeine Maßnahmen und topische Therapieoptionen.

Obwohl bislang für die Rosazea keine kurative Therapie besteht, können verschiedene Optionen zur Behandlung der Symptome und zur Vorbeugung von Exazerbationen empfohlen werden. Neben Selbsthilfemaßnahme wie der Vermeidung von Triggerfaktoren und einer geeigneten Hautpflege sollte das Rosazea-Management bei Patienten mit erythematöser und leichter bis schwerer papulopustulöser Rosazea die Anwendung topischer Präparate als First-Line-Therapie umfassen. Da Überlappungen der charakteristischen Rosazea-Symptome im klinischen Alltag die Regel sind, sollte die medikamentöse Therapie auf die individuellen Symptome zugeschnitten werden; auch eine Kombinationstherapie kann erforderlich sein. Zu den für die Behandlung der Hauptsymptome der Rosazea zugelassenen Wirkstoffen gehören Brimonidin gegen das Erythem sowie Ivermectin, Metronidazol oder Azelainsäure gegen entzündliche Läsionen. Ihre Wirksamkeit wurde in zahlreichen validen, gut kontrollierten Studien belegt. Darüber hinaus existieren verschiedene nicht zugelassene topische Behandlungsmöglichkeiten, deren Wirksamkeit und Sicherheit noch in größeren, kontrollierten Studien zu untersuchen ist.

State of the art: systemic rosacea management.

Based on numerous trials, oral tetracyclines and most commonly their second-generation derivative doxycycline have become the main pillar in systemic rosacea treatment. However, the only preparation that has been approved so far in this setting is 40 mg doxycycline in an anti-inflammatory dosage and with a modified release formulation. With the introduction of this once-daily, non-antibiotic dosing of doxycycline, oral therapy is more commonly prescribed as first-line treatment in moderate to severe papulopustular rosacea. In addition, topical and oral strategies are often used in combination due to the more substantial improvements compared to monotherapy. Although several other non-approved oral agents like macrolides, isotretinoin, and carvedilol have been evaluated for systemic treatment and showed promising results, yet the experience with these drugs in rosacea is limited, and thus they should be reserved for special situations.

Aktueller Stand der systemischen Rosazea-Therapie.

Basierend auf den Daten zahlreicher Studien sind orale Tetracycline - und hier insbesondere Doxycyclin als Tetracyclin der zweiten Generation - die Grundpfeiler der systemischen Rosazea-Therapie. Bisher ist dafür jedoch nur Doxycyclin 40 mg in antientzündlicher Dosierung mit veränderter Wirkstofffreisetzung zugelassen. Seit Einführung der Therapie mit Doxycyclin einmal täglich in nicht antibiotischer Dosierung wird die orale Therapie häufiger als Erstbehandlung bei mittelschwerer bis schwerer papulopustulöser Rosazea verschrieben. Oft wird diese Behandlung aufgrund der besseren Wirksamkeit im Vergleich zur Monotherapie auch mit einer topischen Behandlung kombiniert. Obwohl in der Systemtherapie weitere, nicht zugelassene Wirkstoffe wie Makrolide, Isotretinoin und Carvedilol mit viel versprechenden Ergebnissen untersucht wurden, ist die vorliegende Erfahrung bisher begrenzt, so dass diese Substanzen speziellen Situationen vorbehalten bleiben sollten.

Pathogenese und Klinik der Rosazea als Schlüssel für eine symptomorientierte Therapie.

Rosazea ist eine häufige chronisch-entzündliche Hauterkrankung, die typischerweise bei Erwachsenen vorkommt und das Gesicht betrifft. Synonyme der Rosazea sind Acne rosacea, Kupferfinne, Rotfinne, Couperose und Rosacea. Die Erkrankung ist durch einen chronischen und schubartigen Verlauf gekennzeichnet und wird durch ein genetisch prädisponiertes, multifaktorielles Geschehen bedingt. Ein vermehrtes Auftreten wird bei hellem Hauttyp und positiver Familienanamnese verzeichnet. Die charakteristischen Rosazea-Symptome manifestieren sich vorwiegend, aber nicht ausschließlich zentrofazial, wobei Stirn, Nase, Kinn und die Wangen maßgeblich betroffen sind. Dabei werden unterschiedliche Hauptsymptome voneinander unterschieden, anhand derer eine Klassifikation der verschiedenen klinischen Bilder vorgenommen werden kann. Eine Klassifizierung wird oftmals jedoch nicht der klinischen Realität gerecht, da die verschiedenen Symptome häufig gemeinsam auftreten. Diese Übersichtarbeit führt in die Pathogenese und Klinik der Rosazea ein und plädiert für einen symptomorientierten Therapieansatz.

Rosacea Management: Update on general measures and topical treatment options.

Although there is presently no cure for rosacea, there are several recommended treatment options available to control many of the symptoms and to prevent them from getting worse. In addition to self-help measures like avoidance of trigger factors and proper skin care, rosacea management should include topical medications as one of the first-line choices for patients with erythematous and mild to severe papulopustular rosacea. Since mixed forms of characteristic rosacea symptoms are more common, medical treatment must be symptom-tailored for each individual case and will often involve a combination therapy. Approved topical agents for the major symptoms of rosacea encompass brimonidine for erythema and ivermectin, metronidazole or azelaic acid for inflammatory lesions, all of which have shown their efficacy in numerous valid, well-controlled trials. In addition, there are several other, not approved topical treatments which are possible options that require further validation in larger well-controlled studies.

Prevalence of rosacea in the general population of Germany and Russia - The RISE study.

BACKGROUND: There is an unmet need for general population-based epidemiological data on rosacea based on contemporary diagnostic criteria and validated population survey methodology. OBJECTIVE: To evaluate the prevalence of rosacea in the general population of Germany and Russia. METHODS: General population screening was conducted in 9-10 cities per country to ensure adequate geographic representation. In Part I of this two-phase study, screening of a representative sample of the general population (every fifth person or every fifth door using a fixed-step procedure on a random route sample) was expedited with use of a questionnaire and algorithm based on current diagnostic criteria for rosacea. Of the subjects that screened positive in the initial phase, a randomly selected sample (every third subject) t`hen underwent diagnostic confirmation by a dermatologist in Part II. RESULTS: A total of 3052 and 3013 subjects (aged 18-65 years) were screened in Germany and Russia respectively. Rosacea prevalence was 12.3% [95%CI, 10.2-14.4] in Germany and 5.0% [95%CI, 2.8-7.2] in Russia. The profile of subjects with rosacea (75% women; mean age of 40 years; mainly skin phototype II or III, majority of subjects with sensitive facial skin) and subtype distribution were similar. Overall, 18% of subjects diagnosed with rosacea were aged 18-30 years. Over 80% were not previously diagnosed. Within the previous year, 47.5% of subjects had received no rosacea care and 23.7% had received topical and/or systemic drugs. Over one-third (35% Germany, 43% Russia) of rosacea subjects reported a moderate to severe adverse impact on quality of life. CONCLUSION: Rosacea is highly prevalent in Germany (12.3%) and Russia (5.0%). The demographic profile of rosacea subjects was similar between countries and the majority were previously undiagnosed.

Eumycetoma and actinomycetoma--an update on causative agents, epidemiology, pathogenesis, diagnostics and therapy.

Mycetoma is a chronic putrid infection of the cutaneous and subcutaneous tissue concerning predominantly the feet, and more rarely other body parts. Mycetoma can be caused by both fungi (eumycetoma) and bacteria (actinomycetoma). Mode of infection is an inoculation of the causative microorganism via small injuries of the skin. The clinical correlate of both forms of mycetoma is tumescence with abscesses, painless nodules, sinuses and discharge. The latter is commonly serous-purulent and contains grains (filamentous granules) which can be expressed for diagnostic purposes. Distinctive for both eumycetoma and actinomycetoma, are the formation of grains. Grains represent microcolonies of the microorganism in vivo in the vital tissue. The most successful treatment option for eumycetomas offers itraconazole in a dosage of 200 mg twice daily. This triazole antifungal is considered as 'gold standard' for eumycetomas. Alternatively, the cheaper ketoconazole was widely used, however, it was currently stopped by the FDA. Actinomycetomas should be treated by the combination of trimethoprim-sulphamethoxazole (co-trimoxazole 80/400 to 160/800 mg per day) and amikacin 15 mg/kg body weight per day. Mycetomas are neglected infections of the poor. They are more than a medical challenge. In rural areas of Africa, Asia and South America mycetomas lead to socio-economic consequences involving the affected patients, their families and the society in general.

[Male circumcision from an infectiological point of view]. / Zirkumzision des Mannes aus infektiologischer Sicht.

BACKGROUND: In May 2012 a German regional court (Cologne) declared circumcision on religious grounds in minor boys an illegitimate bodily harm. This led to substantial political and religious discussions, because Jews as well as Muslims consider circumcision as an indispensable element of their religion. Still in 2012 a "circumcision law" was passed by the Federal Council of Germany, which continues to allow circumcision in boys "performed under strict medical conditions". OBJECTIVE: How male circumcision is assessed in terms of infectiology (pros and cons)? METHOD: Electronic databases were searched for articles about the infection risks of foreskin surgery, and the efficacy of circumcision in reducing the risks of sexual transmission of HIV, herpes viruses, HPV, treponema pallidum, chlamydia, hemophilus ducrey and Neisseria gonorrhoeae. RESULTS: Contra circumcision: The highest risk of neonatal circumcision is hemorrhage (35 %). Among infections surgical wound infection (10 %), meatitis urethrae (8-20 %) and urinary tract infections (2 %) are frequent (depending on the surgical technique). Severe complications like penile necrosis or lethal sepsis are rare (1:20,000). Pro circumcision: Circumcised boys have a reduced risk for urinary tract infections in childhood (1:10). Compared to uncircumcised men circumcised adults have a 50-60 % reduced risk of becoming infected with viral sexually transmitted infections (STIs; HIV, HPV and HSV). This advantage of circumcision is also discussed for the transmission of bacterial STIs (e.g. syphilis and chancroid), but the analysis of different clinical studies is still controversial. DISCUSSION AND CONCLUSION: Neonatal circumcisions (and circumcision in early childhood) are irreparable interventions in the physical integrity, with very few medical indications. The risk of complications is dependent on the education of the circumciser (ritual, medical), analgesia and hygiene. Circumcisions should be performed under optimal surgical and hygienic conditions in informed and self-determined young men only. In adolescents and adults circumcision reduces the risk of the transmission of viral STIs (HIV, HSV, HPV) and there is also probably some effect on the sexual transmission of treponema pallidum and hemophilus ducreyi (insufficient, controversial data). The role of circumcision as an effective procedure to reduce the transmission of STIs is still under discussion, because important additional factors like sexual risk behavior (e.g. unprotected sexual intercourse, promiscuity) have a strong influence on STI epidemiology.

Treatment of recalcitrant facial verrucae vulgares with sinecatechins (greentea catechins) ointment.

BACKGROUND: Facial verrucae vulgares are benign, but disfiguring skin manifestations of human papilloma virus infection. They are found as verrucae planae juveniles in young adults, but also as common warts in immunocompromised or atopic patients. OBJECTIVE: To find an alternative, non-surgical treatment for a young man with atopic dermatitis and facial warts, who had not responded to 5-FU ointment, waterfiltered infrared A (wIRA) irradiation and topical retinoids. METHODS: Topical treatment with a sinecatechins 10% ointment (Veregen(TM) ) as approved for genital warts thrice daily for 3 weeks in a 34-year-old man with atopic dermatitis RESULTS: Complete remission of all facial warts was achieved within 20 days. Few side-effects were observed (initially some light skin irritation only). CONCLUSION: In this case, topical sinecatechins proved to be a well-tolerated and effective alternative to treat recalcitrant facial warts without surgery.

[Diagnosis and therapy of genitoanal ulcers of infectious etiology]. / Diagnostik und Behandlung genitoanaler Ulzera infektiöser Genese.

BACKGROUND/OBJECTIVES: In this review article the diagnostic and therapeutic principles of genital ulcers of infectious etiology are highlighted. Besides frequent causative infections rare but relevant diseases in the differential diagnosis are discussed in detail. MATERIAL AND METHODS: A Pubmed literature search was carried out, guidelines from different task groups and clinical experiences are presented. RESULTS: Infections with herpes simplex virus (first) and syphilis (second) are still the most common causes of infectious genital ulcers. An endemic occurrence, previously rare in Europe, has been observed in recent years. Particular risk groups, such as men who have sex with men (MSM), sex workers or sex tourists are affected. Even less common locations, such as the mouth or the rectum, lymphogranuloma venereum (LGV) and atypical clinical symptoms (e.g. pelvic pain in pelvic lymphadenopathy with LGV) must be considered in the differential diagnosis. CONCLUSION: In recent years sexually transmitted infections (STI) have shown a significant increase in western industrialized nations. In all cases with unclear findings in the genital and anal areas (and also in the oral cavity) STI diseases must be reconsidered in the differential diagnosis.

[Topical therapy of rosacea]. / Topische Therapie der Rosazea.

Metronidazole and azelaic acid are the only topical medications approved for rosacea. All other topical treatments for rosacea and its special forms are used off-label. Topical steroids are not indicated in rosacea, because of their side effects (induction of steroid rosacea, high risk of facial skin atrophy, and high risk of rebound after cessation of therapy). Topical as well as systemic steroids are allowed only as initial and short term therapy for acute forms of rosacea (e.g. rosacea fulminans). Papular and pustular rosacea is the major indication for topical therapy. Sebaceous gland and connective tissue hyperplasia in glandular-hypertrophic rosacea as well as erythema in erythematous rosacea do not respond well to topical measures. A new active substance, the alpha-2-adrenoreceptor agonist brimonidine, will be approved soon for the topical treatment of erythema in rosacea. All severe forms of rosacea should initially be treated with a combination of topical and systemic agents. After improvement of the clinical symptoms, topical treatment alone is usually adequate to maintain the control.
