Abstract
Kaposi sarcoma (KS) is a vascular proliferative tumor caused by human herpesvirus 8. At present, the treatment of KS is difficult and refractory. Here, we report a 68-year-old man who was diagnosed with a classical KS with tinea pedis and onychomycosis, infected by Trichophyton rubrum, and treated with itraconazole and thalidomide after locational excision of several bigger nodules. The lesions were relieved during treatment, and recurred after discontinuation. Retreatment still achieved good effect and the therapy was tapered down after control. After the whole course of treatment, the skin lesions subsided significantly without obvious adverse reactions, which showed that itraconazole combined with thalidomide may be another effective and safe treatment for KS in some cases.

Abstract
BACKGROUND AND OBJECTIVE Naftifine, an allylamine, is highly effective against tinea pedis and exhibits relatively greater affinity to skin and nail beds, possibly due to its high lipophilicity. To study the efficacy and safety of naftifine 2% gel in an Indian population, a phase III multicentre double-blind, comparative, parallel-group study was conducted in comparison with miconazole 2% gel in patients with interdigital tinea pedis, with mild to moderate symptoms. PATIENTS AND METHODS Patients presenting with mild to moderate signs and symptoms of interdigital tinea pedis and mycologically confirmed tinea infection were randomised to either naftifine hydrochloride 2% gel (n = 112) or miconazole 2% gel (n = 112) in 1:1 ratio. All patients were treated for 2 weeks with a follow-up of up to 12 weeks. Study evaluations were done at the end of 2, 6, and 12 weeks. The primary efficacy endpoint was the proportion of patients achieving clinical cure at week 6 (± 4 days) and secondary endpoints were the mycological cure at week 6 and week 12 and complete cure at week 12. RESULTS At the end of week 6, clinical cure was 54.55% and 50.00% in the naftifine and miconazole groups (p = 0.4960), respectively, and it was increased to 78.18% and 76.36% in the naftifine and miconazole group (p = 0.7455) at the end of week 12. Mycological and clinical cure were similar in the naftifine and miconazole groups at week 6 and week 12. The safety and tolerability profiles of both treatments were similar. CONCLUSIONS Naftifine 2% gel was efficacious and safe for the treatment of mild to moderate interdigital tinea pedis. Its clinical effectiveness was comparable to that of miconazole 2% gel.

Abstract
BACKGROUND Tinea pedis is the most common dermatophyte infection. Treatment is critical to alleviate pruritic symptoms, to reduce the risk for secondary bacterial infection, and to limit the spread of infection to other body sites or other individuals. The objective of this study was to compare the abilities of econazole nitrate topical foam, 1% and ketoconazole cream (2%) to reduce pruritus, thus improving quality of life, and to determine patient preference for the foam product versus the cream product in patients with interdigital tinea pedis. STUDY DESIGN A single-center, investigator-blinded, observational pilot study was conducted to compare econazole nitrate topical foam (1%) to ketoconazole cream (2%). In this split-body study, 20 subjects received both econazole nitrate topical foam and ketoconazole cream and applied the medications daily to either the right or left foot for 14 days. Improvements in patient quality of life (pruritus) and patient preference were measured using the pruritus visual analog scale (VAS), Skindex-16, and patient preference questionnaires. RESULTS Nineteen subjects completed the study and one subject was lost to follow-up. Reductions in VAS scores of econazole nitrate topical foam were significantly greater than those of ketoconazole cream, indicating the superiority of the econazole nitrate foam in reducing pruritus. Skindex-16 data showed significant reductions in total scores and individual domains, including patient symptom, emotional, and functional domains, by the final visit. Since each subject received both medications the questionnaire was not medication-specific. Responses to patient preference questionnaires showed that econazole nitrate topical foam,1% was rated as "good" or "excellent" in all measures assessed. One adverse event was noted. CONCLUSION In patients with interdigital tinea pedis, application of econazole nitrate topical foam 1% twice daily for two weeks was clinically effective and significantly superior to ketoconazole cream 2% in reducing pruritus.

Abstract
In this study, we investigated the role of successive potassium hydroxide (KOH) tests for the diagnosis of tinea pedis with different clinical presentations. The study included 135 patients with 200 lesions that were clinically suspicious for tinea pedis. Three samples of skin scrapings were taken from each lesion in the same session and were examined using a KOH test. This study offers an inexpensive, rapid, and useful technique for the daily practice of clinicians and mycologists managing patients with clinically suspected tinea pedis.

Abstract
Fungal infection of the nails is an increasingly recognized disease in infants and children. However, it can be difficult to distinguish clinically from other nail dystrophies. In addition, many mistakenly believe that onychomycosis does not occur in childhood. Under-recognition of this infectious disorder therefore occurs. Although many consider "nail fungus" a trivial cosmetic concern, it can lead to discomfort, risk of secondary infection, and a more significant health threat in immunocompromised or diabetic individuals. It should always be considered in the differential diagnosis of nail plate disorders in children as it is one of the more common causes.</p> <p>Here we review the latest data on prevalence of the disease, reasons for its relatively low incidence compared with adults, and important predisposing factors. It is important to confirm the clinical diagnosis of onychomycosis in children, and affected individuals should be examined for concomitant tinea pedis. As familial disease often occurs, it is important to check parents and siblings as well for onychomycosis and tinea pedis.</p> <p>Treatment of onychomycosis is challenging, and recurrence appears to be more common in children than in adults. Prolonged systemic antifungal therapy is commonly required. However, pediatric practitioners and parents alike hesitate when asked to treat young children with a systemic drug that requires laboratory monitoring and can have systemic toxicities. Due to their thinner, faster-growing nails, children are theoretically more likely to respond to topical monotherapy than adults, and therefore good candidates for topical antifungal therapy.</p> <p>The clinical data on the use of topical antifungals in pediatric onychomycosis is scarce. We review data that exist from case reports and small clinical trials. New topical antifungals are now available that afford better nail penetration and additional delivery routes to the site of infection. Pediatric trials are now on-going, and should clarify the usefulness of these agents in children.

Abstract
Econazole nitrate topical foam, 1%, is indicated for the treatment of interdigital tinea pedis caused by <em>Trichophyton rubrum, Trichophyton mentagrophytes,</em> and <em>Epidermophyton floccosum</em> in patients 12 years of age and older. The symptom of itch or pruritus was evaluated in two randomized, double-blind, parallel-group, vehicle-controlled, multicenter Phase III studies in which econazole foam was compared with foam vehicle in subjects with interdigital tinea pedis. A thin, uniform layer of study treatment was applied once daily to all clinically affected interdigital regions of both feet for four weeks. At baseline, at least 69% of all subjects had moderate to severe itch. Throughout the duration of both studies, numerically econazole foam was numerically superior to vehicle in achieving absence of itch. After the cessation of treatment, from day 29, itching continues to improve until day 43 in the active treatment group, whereas there is no evident continued improvement within the vehicle foam groups. At day 43, in the active treatment groups, 83% in Study 1 and 71% in Study 2 achieved complete absence of itching. Using less stringent criteria, for the econazole nitrate foam arm, achieving no itch or mild itch (0 or 1), in Study 1, 95% and 86.8% in Study 2 achieved this outcome. Tolerability of the products was excellent with few treatment-related adverse events. In summary, econazole foam decreased the burden of itch as early as day 8 in patients with interdigital tinea pedis, and this improvement continued after cessation of treatment. <br /><br /> <em>J Drugs Dermatol.</em> 2016;15(9):1111-1114.

Abstract
In recent years, new topical antifungals have emerged for the treatment and management of tinea pedis, but all have been investigated and approved for the treatment of interdigital tinea pedis. Moccasin tinea pedis has not been recognized by governing bodies as a definable and treatable disease entity separate from interdigital tinea pedis at this time. Thus, creating randomized, controlled clinical trials to investigate moccasin tinea pedis is a challenge without an agreed upon definition of the disease state, treatment regimen, and treatment course. Considering systemic therapy issues and the lack of data from large trials demonstrating safety and efficacy in the topical management of this clinical presentation, an unmet need has been created for a topical antifungal agent that can treat moccasin tinea pedis. Naftifine 2% gel, an allylamine, was studied in a clinical trial that enrolled patients who had interdigital or both interdigital and moccasin-type tinea pedis. In the moccasin group, the primary efficacy endpoint of complete cure at week 2 (end of treatment) was 1.7% (gel) vs 0.9% (vehicle) and week 6 (four weeks post-treatment) was 19.2% (gel) vs 0.9% (vehicle). Naftifine 2% cream in combination with urea 39% also showed improvement in hyperkeratotic moccasin tinea pedis.

Abstract
Tinea pedis is a frequently encountered dermatophytosis affecting the superficial skin of the feet, primarily of adults. The prevalence of tinea pedis has increased over the last several decades due to an increase in multiple risk factors. Infection from dermatophytes is most common, but infection from other fungi can also result in tinea pedis. Four distinct clinical presentations occur: interdigital, moccasin, vesicular, and acute ulcerative types. A variety of physical exam findings can help the clinician identify patients with tinea pedis.

Abstract
Tinea infections are caused by dermatophytes and are classified by the involved site. The most common infections in prepubertal children are tinea corporis and tinea capitis, whereas adolescents and adults are more likely to develop tinea cruris, tinea pedis, and tinea unguium (onychomycosis). The clinical diagnosis can be unreliable because tinea infections have many mimics, which can manifest identical lesions. For example, tinea corporis can be confused with eczema, tinea capitis can be confused with alopecia areata, and onychomycosis can be confused with dystrophic toenails from repeated low-level trauma. Physicians should confirm suspected onychomycosis and tinea capitis with a potassium hydroxide preparation or culture. Tinea corporis, tinea cruris, and tinea pedis generally respond to inexpensive topical agents such as terbinafine cream or butenafine cream, but oral antifungal agents may be indicated for extensive disease, failed topical treatment, immunocompromised patients, or severe moccasin-type tinea pedis. Oral terbinafine is first-line therapy for tinea capitis and onychomycosis because of its tolerability, high cure rate, and low cost. However, kerion should be treated with griseofulvin unless Trichophyton has been documented as the pathogen. Failure to treat kerion promptly can lead to scarring and permanent hair loss.

Abstract
The aim of this study was to determine the prevalence of dermatomycosis and the risk factors in those who perform their prayers in the mosques in the city center of Adana Province. The diagnosis of dermatomycosis was made on the basis of direct microscopy and/or culture in addition to clinical findings. Among 461 subjects, 136 (29.5%) had tinea pedis, 23 (5.0%) had tinea unguium, and 21 (4.5%) had both infections simultaneously, with a resulting total of 180 (39.0%) cases of dermatomycosis. The causative agents by frequency were: Trichophyton rubrum (67.0%), T. mentagrophytes var. interdigitale (31.1%), and Candida albicans (1.9%). The prevalence of the foot dermatomycosis was found to be high among those who practiced ablution 3-5 times a day and did not dry their feet immediately, who used rubber shoes, and/or who shared their shoes. Pedal dermatophyte infection seems to be a major problem among the adult Muslim male population regularly attending mosques especially in 5th and 6th decades of life.

Abstract
The diagnosis of tinea pedis is usually confirmed by microscopy and culture of skin scrapings. Isolating dermatophytes by fungal culture gives more reliable proof of infection and has the advantage of identifying the causative organisms. Nevertheless, culture examination is complementary to microscopy and is not routinely performed because it is time- and cost-consuming. Herein, we propose a new culturing method, the 'finger-sampling method', for collecting dermatophytes from patients' toe webs using the examiner's fingertip as a sample collection tool. Using this method, four toe webs of a foot can be examined at one time on one culture dish. Every toe web of 50 patients with untreated tinea pedis were examined, and dermatophytes were grown from 83 out of 107 (78%) KOH positive toe webs. The isolation ratio by the finger-sampling method was comparable to that by traditional slant culture of skin scrapings performed by skilled practitioners. Culture results were also positive in 19 out of 53 (36%) diseased but KOH negative toe webs and in 38 (16%) normal toe webs, suggesting the existence of unidentified infection. Additionally, we confirmed the efficacy of this method for detecting dermatophyte attachment on the healthy toe web skin of volunteers who had just been exposed to contaminated areas, i.e. Japanese public baths or a bath mat stepped on by a patient disseminating dermatophyte propagules.

Abstract
Disorders of the dermis and the nails on the feet are common. Despite the simplicity of the skin and nail disorders of the foot, they can be debilitating and impact the patient's ability to ambulate and perform activities of daily living. Diagnosis in most cases is confirmed on physical examination alone. Diligent care of skin and nail disorders can prevent further pathology involving the deeper structures of the foot and allow the patient to fully participate in their usual activities.

Abstract
Infective skin conditions represent a significant element of the caseload for sea-going and shore-side clinicians. They are common within the wider military setting due to the frequent requirement to live in close proximity to others in conditions which favour the spread of skin and soft tissue infections (SSTI). Within the UK civilian population, 24% of individuals see their family doctor for skin conditions each year, accounting for 13 million primary care consultations annually. Of these, almost 900,000 were referred to dermatologists in England in 2009-2010 and resulted in 2.74 million secondary care consultations. Several recent articles have highlighted the problem of Panton-Valentine Leukocidin Staphylococcus aureus (PVL-SA) infection and carriage in sailors on submarines, and soldiers deployed to Afghanistan. However, the majority of published articles relate to land-based military personnel. This article aims to provide an overview of the most common infective skin conditions presenting among Naval personnel (based on the authors' experience), illustrated by several case studies, together with an approach to their diagnosis and management.

Abstract
Diabetes mellitus affects all socioeconomic and age groups and its incidence is rapidly increasing worldwide. The diabetic foot complication represents one of the most complex and serious complications in these patients. Fungal infections can also contribute to the severity of the diabetic foot. The aim of the present study was to evaluate the prevalence of foot skin and toenail mycosis in a group of 75 patients with diabetic foot complication and in a matched control group. Diabetic patients showed onychomycosis in 53.3% and foot skin mycosis in 46.7% of the cases, with a prevalence of both fungal infections significantly higher than that observed in the control group. At least one type of these fungal infections was present in 69.3% of diabetic subjects with a highly significant difference compared to control group (P<0.001). Trichophyton rubrum and Trichophyton interdigitale were the most common species responsible of both nail and skin infections. Candida spp, Fusarium spp, Aspergillus spp and other moulds. were found in about 1/3 onychomycosis. Previous toe amputation was significantly associated with both skin and nail mycosis. The present study confirms that both tinea pedis and onychomycosis have a high prevalence in subjects suffering from diabetic foot complication, and that the problem of fungal infections of the foot in diabetic subjects is still highly underestimated. Consequently, there is an important clinical rationale for careful mycological examination of diabetic foot and an adequate treatment tailored for each individual patient according to the fungal species involved.

Abstract
Persistent superficial skin infection caused by multiple fungi is rarely reported. Recently, a number of fungi, both opportunistic and persistent in nature were isolated from the foot skin of a 24-year old male in Malaysia. The fungi were identified as Candida parapsilosis, Rhodotorula mucilaginosa, Phoma spp., Debaryomyces hansenii, Acremonium spp., Aureobasidium pullulans and Aspergillus spp., This is the first report on these opportunistic strains were co-isolated from a healthy individual who suffered from persistent foot skin infection which was diagnosed as athlete's foot for more than 12 years. Among the isolated fungi, C. parapsilosis has been an increasingly common cause of skin infections. R. mucilaginosa and D. hansenii were rarely reported in cases of skin infection. A. pullulans, an emerging fungal pathogen was also being isolated in this case. Interestingly, it was noted that C. parapsilosis, R. mucilaginosa, D. hansenii and A. pullulans are among the common halophiles and this suggests the association of halotolerant fungi in causing persistent superficial skin infection. This discovery will shed light on future research to explore on effective treatment for inhibition of pathogenic halophiles as well as to understand the interaction of multiple fungi in the progress of skin infection.

Abstract
Interdigital erosions are frequently due to tinea pedis. However, other infectious conditions, such as candidiasis, erythrasma or bacterial infections, can generate lesions that cannot be differentiated at the clinical level. Microbiological tests are therefore necessary. This clinical case shows a man with interdigital lesions of 10 months of evolution that are not responding to antifungal treatment.

Abstract
BACKGROUND Itchy maceration of the toe webs is common in warm and humid weather. Some cases do not respond to treatment for tinea or eczema. METHODS Patients with foot intertrigo with a poor response to antifungal or antiinflammatory treatment from 2004 to 2009 were included in this study. Their general characteristics were recorded. Bacterial and fungal cultures as well as potassium hydroxide preparations were performed. RESULTS We recorded 32 episodes of foot bacterial intertrigo in 17 patients. The disease was more common in men (82%) and the mean age of the patients was 59 years. The main clinical finding was maceration of the toe webs. The majority of bacterial cultures grew mixed pathogens (93%). Pseudomonas aeruginosa, Enterococcus facealis and Staphylococcus aureus were the most common pathogens. Autoeczematization was present in 50% of the 32 disease episodes. CONCLUSION Foot bacterial intertrigo is not a rare condition and can easily be confused with interdigital tinea or eczematous dermatitis. Proper identification of bacterial organisms is critical for early effective antibiotic therapy. Patients should be instructed about proper foot hygiene, which is important to prevent recurrent infections.

Abstract
The aim of this study was to determine the frequency of tinea pedis and manuum (dermatophyte infections of the hands and feet) in adults in rural areas of Turkey, the risk factors and self-administered treatment options. A total of 2,574 people living in a rural area were enrolled in the study. Participants were asked demographic data, hygienic habits in a questionnaire. KOH preparations and culture were performed from suspicious lesions. Medical and alternative therapy methods and former dermatophytosis diagnosis history were taken from the respondents with suspicious lesions. Microbiological samples were taken from 285 (11.1%) participants. Culture was positive in 109 (4.2%) of those. The most common agent was Trichophyton rubrum. The predisposing factors were found as age older than 40, male gender and obesity. Forty-nine (44.9%) of patients had taken a medical therapy, 56 (51.4%) had performed non-medical methods (cologne, Lawsonia inermis-Henna and softener creams). Patient's education about the treatment compliance is important.

Abstract
AIM Observational study of all incident Tinea pedis cases, realised from 2001 to 2007 at the Dermatology Clinic of the University of Cagliari, Italy, which is the main reference centre for dermatologic diseases in central southern Sardinia. METHODS All patients referred for foot inflammatory pathologies were included in the study. Samples of all clinically visible lesions were taken for mycological examination (20% KOH and culture). When lesions were absent samples were also taken from the IV inter-digital space of both feet to identify eventual sane carriers. Detailed anamneses investigated work, life habits, sports and predisposing conditions such as hyperhidrosis and previous pathologies of the feet. RESULTS The study enrolled 1568 patients, of which 918 (510 male-408 female) presented clinical manifestations whereas other 650 (426 male-224 female) were asymptomatic. Tinea pedis was diagnosed in 232 (14.79%), 163 male-69 female aged between 11 and 78 years, all in the group with clinical manifestations. The identified dermatophytes were Trichophyton mentagrophytes 115 cases (49.56%), Trichophyton rubrum 110 cases (47.42%) and Epidermophyton floccosum 7 cases (3.08%). Mycological exams in patients without clinical signs were always negative for dermatophytes, while rare colonies of Candida albicans were identified in 3 cases (0.46%). CONCLUSION Tinea pedis represents a common public health problem, which occurs mainly in male ageing from 16 to 45 years, when working and leisure activities are at their maximum. The absence of dermatophytes identification in 650 asymptomatic patients suggests that the sane carrier condition is a very rare event.

Abstract
The data about the prevalence of onychomycosis in patients with psoriasis is contradictory. In this study, we investigated the prevalence of onychomycosis and tinea pedis in patients with psoriasis compared to control group. A total of 60 patients with psoriasis (27 male, 33 female; mean age: 40.8 +/- 17.6 years) and 60 subjects without psoriasis (27 male, 33 female; mean age: 42.8 +/- 17.3 years) who were admitted to dermatology outpatient clinics of our hospital were included to the study. Scrapings from both normal and abnormal toenails as well as toewebs were examined using microscopy and fungal culture. Foot dermatomycosis was diagnosed in 6 (5 onychomycosis and 1 tinea pedis) patients with psoriasis (10%) and in 8 (5 onychomycosis and 3 tinea pedis) control subjects (13.3%) (p > 0.05). The only dermatophyte fungi isolated in both patients with psoriasis and control group were Trichophyton rubrum (75%) and Trichophyton interdigitale (25%). Onychomycosis was more predominant in male psoriatic patients (p = 0.01). Both distero-lateral subungual onychomycosis (DLSO) and total dystrophic onychomycosis were detected in patients with psoriasis, however, DLSO, was the only clinical type in the control group. Pitting is the most typical lesions in nails in patients with psoriasis (p = 0.04). The use of common showers play a role in transmission of foot dermatomycosis (p = 0.04). In this study, psoriasis was not found as a risk factor for onychomycosis. However, onychomycosis is a major problem in psoriatic nails, and mycological methods would be useful in differential diagnosis. Since dermatomycosis is still an important public health problem, it may be controlled by education of the patient about proper foot hygiene and avoiding walking barefooted in shower areas.

Abstract
Posterior ankle and heel pain is common among athletes. The most common injury in this region is that of the Achilles tendon. However, besides the Achilles tendon, pain can originate from a retrocalcaneal bursitis, posterior impingement syndrome, os trigonum syndrome, or flexor hallucis longus tenosynovitis. These pathologies often caused by overuse, but can also occur after trauma. With careful examination, and the help of MRI imaging, the distinction can be made among these pathologies and the more common Achilles tendon problems. Like most overuse injuries, the majority of cases of retrocalcaneal bursitis, posterior impingement, flexor hallucis longus tenosynovitis respond to conservative treatment. However, when this fails, open or arthroscopic surgery can be proposed. Arthroscopy is less aggressive than open surgery, with the added advantage of less patient morbidity, less post-operative pain, and early functional rehabilitation. It is becoming the surgery of choice, especially among athletes.

Abstract
The common dermatophyte genera Trichophyton, Microsporum, and Epidermophyton are major causes of superficial fungal infections in children. These infections (e.g., tinea corporis, pedis, cruris, and unguium) are typically acquired directly from contact with infected humans or animals or indirectly from exposure to contaminated soil or fomites. A diagnosis usually can be made with a focused history, physical examination, and potassium hydroxide microscopy. Occasionally, Wood's lamp examination, fungal culture, or histologic tissue examination is required. Most tinea infections can be managed with topical therapies; oral treatment is reserved for tinea capitis, severe tinea pedis, and tinea unguium. Topical therapy with fungicidal allylamines may have slightly higher cure rates and shorter treatment courses than with fungistatic azoles. Although oral griseofulvin has been the standard treatment for tinea capitis, newer oral antifungal agents such as terbinafine, itraconazole, and fluconazole are effective, safe, and have shorter treatment courses.

Abstract
Propolis is a beehive product known for its anti-inflammatory properties. With its growing use, propolis-induced contact dermatitis is increasing. While the dermatitis mostly occurs on areas directly exposed to propolis, our case presented an additional eczema at a site distant from the primary propolis-induced contact dermatitis twice in the same individual. We diagnosed it as an autosensitization dermatitis associated with propolis-induced allergic contact dermatitis.

Abstract
Generally, diabetic patients are more susceptible to skin infections. Although the overall incidence of skin mycoses in diabetics is not higher as compared with healthy population, diabetics seem to suffer from certain types of mycoses more frequently. They are not only tinea pedum and onychomycosis, but also candidoses (especially candidal balanitis). In older patients, sole tinea is often overlooked. Nevertheless, it impairs integrity of skin and lets in bacterial infections causing diabetic foot and aggravates nail infections. Onychomycosis in diabetics is far from being a cosmetic problem only. On the contrary, it is potentially a very dangerous disease. Hypertrophic and deformed nails damage adjacent skin and their pressure can result in decubital ulceration of neighbouring fingers or nail beds. This condition can even lead to finger gangrene. Therapy of onychomycosis in diabetics and seniors should be specific: the most effective therapeutic procedure proved to be the combination of systemic treatment with terbinafine and atraumatic chemical ablation with subsequent local treatment.

Abstract
OBJECTIVE To assess the role of foot dermatomycosis (tinea pedis and onychomycosis) and other candidate risk factors in the development of acute bacterial cellulitis of the leg. METHODS A case-control study, including 243 patients (cases) with acute bacterial cellulitis of the leg and 467 controls, 2 per case, individually matched for gender, age (+/-5 years), hospital and admission date (+/-2 months). RESULTS Overall, mycology-proven foot dermatomycosis was a significant risk factor for acute bacterial cellulitis (odds ratio, OR: 2.4; p < 0.001), as were tinea pedis interdigitalis (OR: 3.2; p < 0.001), tinea pedis plantaris (OR: 1.7; p = 0.005) and onychomycosis (OR: 2.2; p < 0.001) individually. Other risk factors included: disruption of the cutaneous barrier, history of bacterial cellulitis, chronic venous insufficiency and leg oedema. CONCLUSIONS Tinea pedis and onychomycosis were found to be significant risk factors for acute bacterial cellulitis of the leg that are readily amenable to treatment with effective pharmacological therapy.

Abstract
BACKGROUND The purpose of this study was to evaluate a possible association between tinea pedis (interdigital mycosis) and hyperhidrosis by a case-control-study. PATIENTS AND METHODS 30 otherwise healthy patients (age 22-56 years, 30% female) with mycologically proven tinea pedis and 51 control patients were included. RESULTS 53.3% of the patients with tinea pedis and 33.3% of the control-patients had focal hyperhidrosis defined by gravimetry (definition as > or =30 mg sweat/min) (p-value=0.08). To control for possible confounding variables a multivariate analysis was performed including possible risk factors such as gender, regular visits in sauna and/or swimming pools. Multivariate analysis found a 3.5-fold increased risk for patients with tinea pedis to have hyperhidrosis. CONCLUSION The study supports an association between tinea pedis or interdigital mycosis and focal plantar hyperhidrosis and therefore lends credence to the treatment of hyperhidrosis in patients with tinea pedis.

Abstract
Tinea pedis is a dermatophytic infection with a high prevalence in adults and also occasionally observed in children. We report here two cases of bullous tinea pedis, one due to Trichophyton rubrum in a 6-year-old child and the second due to T. interdigitale in a 10-year-old child. We suggest that, despite the low prevalence of this infection in childhood, a potassium hydroxide test and a culture for fungi should always be performed when a child is examined for an inflammatory eruption of the feet.

BACKGROUND The ideal method for diagnosing onychomycosis is unclear. Mycological investigation is currently the method of choice, although there is a false-negative culture rate of at least 30%. OBJECTIVES To establish a clinical diagnostic aid which may be used alongside laboratory-based mycological tests and in epidemiological studies. METHODS Patients with nail disease (n = 209) were enrolled in the study. The examining clinician completed a questionnaire containing four historical questions and 21 questions related to the clinical findings. All patients had samples taken for mycological analysis. The gold standard for the diagnosis of onychomycosis was a positive result on both direct microscopy and culture of nail samples. Following exclusions, questionnaire responses from 169 patients were analysed using Stata. Multiple logistic regression with forward stepwise selection of variables was performed. RESULTS Both microscopy and culture results were positive in 32% of cases and negative in 42%. Dermatophytes formed the majority of isolates. Four parameters were found to be significantly related to positive mycology results: a history of tinea pedis in the last year, scaling on one or both soles, white crumbly patches on the nail surface, and an abnormal colour of the nail plate. CONCLUSIONS Our results have shown one historical feature and three clinical features to be strongly associated with onychomycosis. The questionnaire has been revised to include only these stems and is being tested further with the aim of achieving a binary definition.

Abstract
BACKGROUND This study examined the incidence of culture-proven tinea pedis in patients who presented with a foot rash clinically suspected to be tinea pedis. METHODS Cultures were taken from 874 patients in 4 dermatology clinics across the country. The incidence of patients with positively cultured tinea pedis was compared with the total number of patients in the study. RESULTS The surprisingly low percentage of patients correctly diagnosed with tinea pedis was determined to be 32%. The remaining 68% of patients either had a nonfungal foot dermatitis or tinea pedis with false-negative cultures. CONCLUSIONS This study demonstrates the need for fungal cultures when patients present with scaling feet as well as the importance of a broad differential diagnosis to ensure timely and appropriate therapy.

Abstract
BACKGROUND The spectrum of organisms causing dermatophytoses is changing continuously. PATIENTS/METHODS Two strains of Trichophyton mentagrophytes var. nodulare are characterized mycologically; both were isolated for the first time in our laboratory within the past 2 years from patients with tinea pedis. RESULTS Distinctive features of Trichophyton mentagrophytes var. nodulare are a bright yellow-orange pigmentation of the thallus, a marked exudation of pigment, and the development of nodular bodies. Trichophyton mentagrophytes var. nodulare is an anthropophilic variety of Trichophyton mentagrophytes causing tinea and onychomycosis. CONCLUSIONS Trichophyton mentagrophytes var. nodulare has been found only very rarely in Germany and is relatively unknown. An increased awareness of this dermatophyte is needed in order to track its possible spread.

Abstract
UNLABELLED BACKGROUND Tinea pedis (athlete's foot) is the most common fungal infection in the general population. Ciclopirox, a broad-spectrum hydroxypyridone antifungal, has proven efficacy against the organisms commonly implicated in tinea pedis; Trichophyton rubrum, T.mentagrophytes and Epidermophyton floccosum. OBJECTIVE Two multicenter, double-blind, clinical studies compared the efficacy and safety of ciclopirox gel with that of its vehicle base in subjects with moderate interdigital tinea pedis with or without plantar involvement. METHODS Three hundred and seventy-four subjects were enrolled and randomized to one of two treatment groups: ciclopirox gel 0.77%, or ciclopirox gel vehicle, applied twice daily for 28 days, with a final visit up to day 50. The primary efficacy variable was Treatment Success defined as combined mycological cure and clinical improvement >/= 75%. Secondary measures of effectiveness were Global Clinical Response, Sign and Symptom Severity Scores, Mycological Evaluation (KOH examination and final culture result), Mycological Cure (negative KOH and negative final culture results) and Treatment Cure (combined clinical and mycological cure). RESULTS At endpoint (final post-baseline visit), 60% of the ciclopirox subjects achieved treatment success compared to 6% of the vehicle subjects. At the same time point, 66% of ciclopirox subjects compared with 19% of vehicle subjects were either cleared or had excellent improvement. Pooled data showed that 85% of ciclopirox subjects were mycologically cured, compared to only 16% of vehicle subjects at day 43, 2 weeks post-treatment. CONCLUSIONS Ciclopirox gel 0.77% applied twice daily for 4 weeks is an effective treatment of moderate interdigital tinea pedis due to T. rubrum, T. mentagrophytes and E. floccosum and is associated with a low incidence of minor adverse effects.

Abstract
Routine care of the legs and feet in the elderly is important in helping to prevent infections, malignancies, and further deterioration. The lower extremities are of particular interest because of the increasing amount of diseases and disorders involving the legs and feet. Foot disorders in the elderly are associated with poor choices in footwear, structural changes, brought on by aging, and inadequate knowledge about prevention and treatment. Conservative treatments along with gait modification provide positive long-term results, although sometimes surgery is necessary for severe foot disorders. Onychomycosis and other nail disorders commonly infect the elderly despite the wide variety of treatment options. The increase in malignancy formation in the elderly is caused by the increase in the elderly population and inadequate treatment of leg ulcers and other chronic lesions. Aging is associated with many dermatologic changes; many of the disorders and diseases of the lower extremities can be managed if detected and treated early. Proper awareness of the signs, symptoms, and care is important.
