“…The only commonality between these studies and ours is the frequency of skin mycoses, which, in addition to bacterial infections, was the second leading cause of infectious skin changes in our patients. This is not surprising since mycoses, especially in the form of tinea manuum and tinea pedis, are very common in the general population with a lifetime prevalence of 6.5-14% 37,38 and 15-25%, 39 respectively.…”

Objective The few psychodermatological studies of primary psychiatric populations so far suggest that parasitic-infectious skin diseases are the most common dermatological comorbidity in more than 70% of psychiatric patients, which should be studied here in a large data bank outside dermatological treatment facilities.Methods In a descriptive-explorative and retrospective study, more than 17,000 patients with primary psychiatric disorders were examined to investigate dermatological comorbidities.Results The proportion of patients with primary mental disorders and additional dermatological disease was 1.24% (n=212). Here, psoriasis (35.4%) and atopic dermatitis (22.6%) were the most frequent dermatological diseases among these 212 patients. Infectious-parasitic skin diseases were present in 13.2% of comorbid patients. The most common mental disorder was a depressive illness, seen in 42.5% (n=90) of patients.Conclusion Our results confirmed the frequent association of depression with psoriasis and atopic dermatitis, indicating the need for the early detection and treatment of such comorbid patients. In contrast, psychiatric inpatients do not appear to suffer from predominantly infectious-parasitic dermatoses.

“…Clinical signs of onychomycosis include thickened, discolored and crumbling nails that may be partially detached from the nail bed . The manifestation of clinical signs is the determining factor that prompts the clinician to perform mycological testing; however, infectious organisms may be present on the skin and in toenails despite the absence of clinical signs of foot or nail infection …”

“…3 The manifestation of clinical signs is the determining factor that prompts the clinician to perform mycological testing; 4 however, infectious organisms may be present on the skin and in toenails despite the absence of clinical signs of foot or nail infection. 5 Previous studies have investigated the presence of fungal organisms in the normal-appearing toenails of patients with dermatophytosis. Davies reported that 9Á0% of 3955 normal, healthy-looking nail samples from patients infected with T. rubrum were either KOH-and/or culture-positive for the fungus.…”

“…Indeed, the average humidity of the fourth interdigital area in the summer was 80%, average maximum humidity was 84%, maximum humidity was 91% and average dew point was 31°C. A humid environment is important for the development of tinea infections; 25,26,28,30,31,33 however, high humidity was not the major factor contributing to the development of tinea manuum, tinea corporis and tinea capitis, 31 but rather the high-temperature and high-humidity environment. Based on these studies, the following three factors can be considered necessary for tinea development: an environment with high temperature and high humidity (temperature and humidity), sufficient dermatophyte adhesion time (time) and fine scratches on the skin or nails (injury).…”

In addition, the length of time that footwear is worn is also thought to be a risk factor for TP.…”

The relation between tinea pedis and the internal environment of footwear has not been scientifically proven. This study aimed to determine whether the internal environment of footwear affects the incidence of tinea pedis and tinea unguium. This cross‐sectional, observatory study involved 420 outpatients who were categorized into non‐tinea, tinea pedis or tinea unguium groups based on mycological analysis. External climatic conditions, and temperature, humidity and dew points inside the patients’ footwear were recorded. Univariate and multivariate analyses were used to determine independent risk factors for tinea pedis and tinea unguium. A significant correlation was found between high temperature/high humidity and dew point of the internal environment of the footwear and the season. Furthermore, those who wore footwear with internal environments characterized by high temperature, high humidity, high‐temperature/high‐humidity and high dew point values had a significantly higher incidence of tinea pedis. The internal dew point correlated with the incidence of tinea pedis, whereas the external temperature correlated with the incidence of tinea unguium. The internal humidity and dew point of footwear as well as the frequency with which footwear with a high‐temperature/high‐humidity internal environment were worn was significantly higher in men than in women. In conclusion, the internal environment of footwear is a risk factor for tinea pedis, and this environment is affected by the season. Moreover, the frequency of tinea pedis among men is related to the internal environment of footwear. The dew point is an appropriate index for evaluating temperature and humidity in relation to tinea pedis.
