The case report literature on ulcus vulvae acutum Lipschütz (UVAL) is scant, and specific guidelines on its diagnosis and treatment are lacking. Our study's aim was to perform a systematic literature review of UVAL in order to formulate a diagnostic and therapeutic algorithm. Using the PRISMA criteria, we searched PubMed and MEDLINE for the terms ‘ulcus vulvae acutum’, ‘Lipschütz ulcer’ and ‘acute genital ulcer AND vulva’. We extracted relevant data on ‘type of article’, ‘patients’ age’, ‘amount and localization of ulcers’, ‘presence of flu‐like symptoms’, ‘prior sexual contacts’, ‘diagnostic workup’ (including histology, blood count and serology such as Epstein–Barr virus testing) and ‘treatment/outcome’. Data were meta‐analysed and comparative analyses were discussed in order to create a diagnostic algorithm and recommendations for management. Twenty‐one publications reporting a total of 60 cases of UVAL were included for analysis. On this basis, we formulated a diagnostic and therapeutic algorithm defined by two major and four minor criteria. The major criteria were (i) acute onset of one or more painful ulcerous lesions in the vulvar region and (ii) exclusion of infectious and non‐infectious causes for the ulcer. The minor criteria were (i) localization of ulcer at vestibule or labia minora, (ii) no sexual intercourse ever (i.e. patient was a virgin) or within the last 3 months, (iii) flu‐like symptoms and/or (iv) systemic infection within 2–4 weeks prior to onset of vulvar ulcer. Use of a symptom‐based treatment algorithm based on our proposed major and minor criteria will improve the diagnosis and management of UVAL.

An observational, exploratory, cross-sectional study was performed to assess whether the presence of atypical naevi (AN) in adolescents is associated with psychological and psychovegetative stress parameters. Fifty-one students of a secondary school in Graz, Austria, completed a defined test procedure consisting of an initial period of rest, a standardised mental stress task, another period rest and a questionnaire, the change-sensitive symptom list (ASS-SYM). Electrocardiogram and blood pressure were recorded continuously. The study population was divided in two groups: probands without AN (NAN, n = 33), and probands with at least one AN (n = 18). We found higher values for the AN group in all scales of ASS-SYM, reaching statistical significance in the dimensions "nervousness and mental tension" (p = 0.025), "psychophysiological dysregulation" (p = 0.020), burden of pain" (p = 0.023) and "general symptoms and problems" (p = 0.031). Regarding physiological parameters, the AN group showed higher vegetative strain reflected in heart rate and heart rate varibility during the periods of rest as well as a reduced baroreceptor sensitivity. On the basis of our results, the presence of AN in adolescents seems to be associated with a higher vegetative arousal. Additionally, participants with AN complained significantly more often about stress-associated general psychological symptoms and problems.

SummaryBackground Incomplete resorption of fructose results in increased colonic hydrogen production and is a frequent cause of abdominal symptoms. The only treatment available is diet. Aim To study whether orally administered xylose isomerase (XI), an enzyme that catalyses the reversible isomerisation of glucose and fructose, can decrease breath hydrogen excretion in patients with fructose malabsorption. Methods Patients received 25 g fructose in 100 mL water together with either placebo or XI capsules. Primary endpoint was the reduction in breath hydrogen excretion, as assessed by the area under the breath hydrogen curve over 4 h (AUC). A secondary endpoint was the reduction in abdominal pain, bloating and nausea assessed on a visual analogue scale (VAS, range: 0–10). A P value

Heparins are widely used for the prophylaxis and treatment of venous thromboembolism. Several types of immunologically mediated reactions to heparins are reported, among them delayed-type hypersensitivity reactions with erythematous, infiltrated itchy plaques at injection sites. We describe a female patient, whose localized reaction from dalteparin was followed by a generalized rash presenting as acute generalized exanthematous pustulosis. Subcutaneous provocation testing showed cross-reactions to enoxaparin, certoparin, reviparin, nadroparin, danaparoid, fondaparinux, but not to pentosan polysulfate. The danaparoid and in a lesser extent the nadroparin patch showed pustules. Within the next day, a generalized rash developed. The upper aspect of her trunk was highly affected and showed discrete pustules. Despite the fact that low molecular-weight heparins are widely prescribed, this is, to our knowledge, the first observation of a pustular drug eruption attributable to this class of substances.

The increase in minimum inhibitory concentrations (MICs) of cephalosporins for Neisseria gonorrhoeae has given rise to concerns regarding potentially untreatable gonococcal infections. The goal was to ascertain the prevalence of gonorrhea in a Viennese patient group and determine resistance patterns. Another objective was to evaluate resistance profiles and MIC values of gonococcal isolates in an Austria-wide surveillance project.From 1999 to 2014, 350,000 individuals were tested for gonococci at the Viennese Outpatient Clinic. In addition, from 2010 to 2014, the MICs of recommended antibiotics was determined in 3,584 gonococcal isolates, initially by agar dilution and breakpoint determination, and, from 2012 onwards, by Etest®.During the observation period, the prevalence of gonorrhea increased eightfold, with a significantly greater number of quinolone, penicillin, and tetracycline- resistant strains. In gonococcal strains isolated from across Austria, there was an increase in cefixime and ceftriaxone MICs toward breakpoints. Twenty-one isolates showed cefixime resistance, and while there was an increase in azithromycin resistance from 0.9 % (2013) to 3.2 % (2014), no resistance to ceftriaxone was observed.Currently, there is no imminent risk of untreatable gonorrhea in Austria. However, continuing the use of gonococcal cultures as a diagnostic tool for establishing resistance profiles is essential in order to monitor trends in the development of Neisseria (N.) gonorrhoeae resistance.

Background: Anogenital warts are a common sexually transmitted disease caused by human papillomaviruses. Despite the fact, that imiquimod and podophyllotoxin represent common topical agents, direct comparative studies lack. This work compares the effectiveness and safety of self-applied imiquimod 5% cream and podophyllotoxin 0.5% solution. Methods: Within 2 years, consecutive patients presenting with untreated anogenital warts were included in a randomized, open label trial. The primary endpoint was complete clearance at the end of treatment (4 weeks after the start with podophyllotoxin, 16 weeks after the start of imiquimod therapy). Side effects were evaluated as a secondary endpoint. Results: A total of 45 patients, 7 women and 35 men, of whom 5 were circumcised, concluded the treatment and were eligible for evaluation. The rates of clearance of baseline warts among treatment groups were 72% (95% confidence interval [CI], 52%-86%) in the podophyllotoxin group and 75% (95% CI, 53%-98%) in the imiquimod group. Statistically, clearance rates were identical (P = 1). The differences in side effects between treatment groups were statistically not significant (P = 0.24). Conclusions: The current study, a direct comparison of both, confirms the previously obtained mathematical data, that imiquimod 5% cream and podophyllotoxin 0.5% solution have an identical beneficial effect on anogenital warts and are associated with identical and acceptable side effects. Both substances constitute effective and safe treatments of untreated anogenital warts in immunocompetent individuals.

Background Acne is an important health issue with a major psychological impact in addition to the physical problems it causes. Objectives To investigate the superiority of mobile teledermatology in the care of patients with high-need facial acne in comparison to outpatient services with particular attention to treatment efficacy, safety, and patient compliance. Further, patient satisfaction with remote care was evaluated. Methods Sixty-nine consecutive patients (f: 25, m: 44, median age: 19 years, range: 13–37 years) were randomly allocated to either the teleconsultation (TCA) or the outpatient consultation (OCA) arm of the trial to receive isotretinoin treatment in weight and severity-dependent dosages over 24 weeks. Acne grading was performed by one examiner using the Global Acne Severity Scale (GEA) and the total lesion counting (TLC). Results Due to noncompliance issues, 17 of 69 (24.6%) patients were excluded from the study, of who 10 had been assigned to the TCA (10/34; 29.4%) and 7 to the OCA (7/35; 20%). Both, in the TCA (GEA-score: ∆ = 2.25; TLC: ∆ = 89.08) and in the OCA (GEA-score: ∆ = 2.0; TLC: ∆ = 91.21) excellent and almost equivalent therapeutic outcomes were achieved. In the TCA, however, less patients experienced adverse reactions (P = 0.55). Even though additional live supervision would have been appreciated in some teledermatology cases, patients were satisfied with the mobile service and no consultation request was created. Conclusion Mobile teledermatology is an efficient, safe and well-accepted tool among patients with high-need acne constituting at least a valuable adjunct to outpatient care services. Further larger studies would be useful to confirm our findings.

Background According to current guidelines, skin testing for hymenoptera venom allergy should be performed in a stepwise manner, maintaining 15- to 20-min intervals between the injections of venom. Given the long-winded procedure of sequential skin testing, we retrospectively explored the safety of simultaneous intradermal testing. Methods Four hundred and seventy-eight consecutive patients with a convincing history of an anaphylactic reaction after a hymenoptera sting were tested. All venom concentrations (0.02 ml of 0.001, 0.01, 0.1, and 1.0 μg/ml of honey bee and wasp venom) were administered simultaneously to the skin. Results Four hundred and seventy-two (98.7%) patients tolerated the simultaneous intradermal test without any side-effects. Only three subjects (0.6%) had a presumed allergic reaction during the test; another three reactions were considered vasovagal. Conclusion Our skin test protocol with four simultaneously injected concentrations of two hymenoptera venoms is safe and permits the investigator to draw rapid conclusions about the individual's sensitization pattern.

An observational, questionnaire-based, cross-sectional study was performed to assess whether differences in coping behaviour (positive and negative strategies) between patients with either a recent diagnosis of malignant melanoma (MM) or with benign dermatological disease, were predictive of the diagnosis. Coping strategies were assessed with the German version of the stress-coping questionnaire (SVF 120) in 46 inpatients for whom surgery was planned at the Department of Dermatology, Medical University of Graz, Austria. Subjects were divided into two groups: patients with non-metastatic MM, and patients with benign dermatological diseases (controls). The risk for the diagnosis "melanoma" decreased with higher values of "situation control" (p = 0.007) and increased with higher values of resignation (p = 0.035) and trivialisation (p = 0.039). More-over, the risk for having a MM with thickness > 1 mm decreased in patients with higher values in positive coping strategies (p

OBJECTIVES: The term histamine intolerance stands for a range of symptoms involving various effector organs after the consumption of histamine-rich food. Our intention was to objectify and quantify histamine-associated symptoms and to analyse whether oral administration of the histamine-degrading enzyme diamine oxidase (DAO) caused a reduction of symptoms. PATIENTS AND METHODS: Four Austrian centres participated. Patients suspected to be histamine intolerant were recruited. The first step consisted in the open oral provocation of these patients with 75 mg of liquid histamine. Patients who developed symptoms were tested in a randomised double blind crossover provocation protocol using histamine-containing and histamine-free tea in combination with DAO capsules or placebo. Main and secondary symptoms (strongest and weaker symptoms based on a ten-point scale) were defined, the grand total of all symptoms of the individual provocation steps was determined and changes in symptoms after administration of DAO were measured. RESULTS: Thirty nine patients reacted to the open histamine provocation and were enrolled in the blinded part. Here, both the main and secondary symptoms were not reproducible. Subjects reacted sometimes unexpectedly and randomly. Regarding the total symptom scores, the differences between the three treatment groups were statistically significant. The intake of DAO demonstrated a statistically significant reduction of histamine-associated symptoms compared to placebo (P = 0.014). CONCLUSIONS: Oral provocation with 75 mg of liquid histamine failed to reproduce histamine-associated single symptoms in many patients. One may suggest that histamine-intolerant subjects reacted with different organs on different occasions. As a consequence, reproducibility of single symptoms alone may not be appropriate to diagnose histamine-intolerance whereas a global symptom score could be more appropriate. The fact, that the intake of DAO capsules compared to placebo led to a statistically significant reduction of total symptom scores, may indirectly point in the same direction.

Perianal dermatitis is probably the most common cutaneous disorder of the genitoanal area. Studies on the epidemiology of causative factors are rare.Over a 4-year period we prospectively studied 126 patients with a presumptive diagnosis of anal eczema. The diagnostic algorithm comprised medical history, inspection, microbiology, laboratory chemistry, patch tests, proctoscopy, and biopsy if appropriate.The age range was 7-82 years and the majority of patients were male (57.1%). Periods of anal symptomatology ranged from 6 days to 120 months and most of the patients (51.6%) had complaints for more than 12 months. The clinical diagnosis in 68 patients (54%) was: intertrigo/candidiasis (42.9%), atopic dermatitis (6.3%), pruritus ani (5.6%), psoriasis (3.2%), skin atrophy from steroid use (2.4%), lichen sclerosus et atrophicus (n = 2), herpes simplex (n = 1), and condylomata acuminata (n = 1). Contact eczema was suspected in 58 patients (46%), but 25 of these (43.1%) showed no contact sensitization.The majority of patients with symptoms of anal eczema suffer from intertrigo/candidiasis, and relevant, causative contact sensitization may be found in only some of them. Patch-testing is a valuable investigative tool only when the patients' own products are included in the test series. Most patients suffer from their perianal complaints for more than 12 months, therefore diligent evaluation is warranted.

Objective Hypobaric hypoxia, physical and psychosocial stress may influence key cardiovascular parameters including blood pressure (BP) and pulse pressure (PP). We investigated the effects of mild hypobaric hypoxia exposure on BP and PP reactivity to mental and physical stress and to passive elevation by cable car. Methods 36 healthy volunteers participated in a defined test procedure consisting of a period of rest 1, mental stress task (KLT-R), period of rest 2, combined mental (KLT-R) and physical task (bicycle ergometry) and a last period of rest both at Graz, Austria (353 m asl) and at the top station Dachstein (2700 m asl). Beat-to-beat heart rate and BP were analysed both during the test procedures at Graz and at Dachstein and during passive 1000 m elevation by cable car (from 1702 m to 2700 m). Results A significant interaction of kind of stress (mental vs. combined mental and physical) and study location (Graz vs. Dachstein) was found in the systolic BP (p = .007) and PP (p = .002) changes indicating that during the combined mental and physical stress task sBP was significantly higher under hypoxic conditions whereas sBP and PP were similar during mental stress both under normobaric normoxia (Graz) and under hypobaric hypoxia (Dachstein). During the passive ascent in cable car less trivialization (psychological coping strategy) was associated with an increase in PP (p = .004). Conclusion Our data show that combined mental and physical stress causes a significant higher raise in sBP and PP under hypoxic conditions whereas isolated mental stress did not affect sBP and PP under hypoxic conditions. PP-reaction to ascent in healthy subjects is not uniform. BP reactions to ascent that represents an accumulation of physical (mild hypobaric hypoxia) and psychological stressors depend on predetermined psychological traits (stress coping strategies). Thus divergent cardiovascular reactions can be explained by applying the multidimensional aspects of the biopsychosocial concept.
