“…Cultures were examined daily during a period of 14 days. Malassezia yeasts were identified as pale ochre‐brown waxy or crumbly colonies with a smooth surface 3,8 . Presumptive Malassezia colonies were subcultured on Sabouraud's glucose agar (SGA; Acumedia, Baltimore, MD, USA) to confirm their lipophilic character 3 …”

Pityriasis versicolor is a common superficial mycoses of the skin. It is now recognized that the causative organisms of this infection are different species of Malassezia. The aim of this study was to determine the distribution of Malassezia species in patients with pityriasis versicolor in Adana, Turkey. In total, 97 patients positive for Malassezia elements, namely, yeast cells and short hyphae in microscopic examination, were included in the study. All samples were inoculated in plates containing modified Dixon's medium. However, only 44 of the patients (45.4%) showed Malassezia spp. in culture. Malassezia globosa (47.7%) was the most commonly isolated species followed by Malassezia furfur (36.4%) and Malassezia slooffiae (15.9%). Mixed Malassezia species were not isolated. In conclusion, M. globosa was found to be the predominant PV isolate in Adana, Turkey.

“…[28] In boys aged 8 months to 18 years (mean 6.4 years), fungus incidence was 44% in uncircumcised boys, compared to 18% in circumcised boys. [29] The fungal species were as follows: Malassezia globosa , Malassezia furfur , Malassezia slooffiae , C. albicans , Candida tropicalis , and Candida parapsilosis . All were present in uncircumcised infants, but none in circumcised infants.…”

Penile inflammatory skin conditions such as balanitis and posthitis are common, especially in uncircumcised males, and feature prominently in medical consultations. We conducted a systematic review of the medical literature on PubMed, EMBASE, and Cohrane databases using keywords “balanitis,” “posthitis,” “balanoposthitis,” “lichen sclerosus,” “penile inflammation,” and “inflammation penis,” along with “circumcision,” “circumcised,” and “uncircumcised.” Balanitis is the most common inflammatory disease of the penis. The accumulation of yeasts and other microorganisms under the foreskin contributes to inflammation of the surrounding penile tissue. The clinical presentation of inflammatory penile conditions includes itching, tenderness, and pain. Penile inflammation is responsible for significant morbidity, including acquired phimosis, balanoposthitis, and lichen sclerosus. Medical treatment can be challenging and a cost burden to the health system. Reducing prevalence is therefore important. While topical antifungal creams can be used, usually accompanied by advice on hygiene, the definitive treatment is circumcision. Data from meta-analyses showed that circumcised males have a 68% lower prevalence of balanitis than uncircumcised males and that balanitis is accompanied by a 3.8-fold increase in risk of penile cancer. Because of the high prevalence and morbidity of penile inflammation, especially in immunocompromised and diabetic patients, circumcision should be more widely adopted globally and is best performed early in infancy.

“…Penile candidiasis was reported in 7.7% of uncircumcised men versus 4.9% of circumcised men in a large Australian survey . In boys aged 8 months to 18 years (mean 6.4 years), the prevalence of fungal infection was 44% in uncircumcised boys versus 18% in circumcised boys . The fungal species were, in order of decreasing prevalence: Malassezia globosa , M. furfur , M. slooffiae , C. albicans , C. tropicalis , and C. parapsilosis .…”

Objective To systematically evaluate evidence against male circumcision (MC). Methods We searched PubMed, Google Scholar, EMBASE and Cochrane databases. Results Database searches retrieved 297 publications for inclusion. Bibliographies of these yielded 101 more. After evaluation we found: Claims that MC carries high risk were contradicted by low frequency of adverse events that were virtually all minor and easily treated with complete resolution. Claims that MC causes psychological harm were contradicted by studies finding no such harm. Claims that MC impairs sexual function and pleasure were contradicted by high‐quality studies finding no adverse effect. Claims disputing the medical benefits of MC were contradicted by a large body of high‐quality evidence indicating protection against a wide range of infections, dermatological conditions, and genital cancers in males and the female sexual partners of men. Risk‐benefit analyses reported that benefits exceed risks by 100‐200 to 1. To maximize benefits and minimize risks, the evidence supported early infant MC rather than arguments that the procedure should be delayed until males are old enough to decide for themselves. Claims that MC of minors is unethical were contradicted by balanced evaluations of ethical issues supporting the rights of children to be provided with low‐risk, high‐benefit interventions such as MC for better health. Expert evaluations of case‐law supported the legality of MC of minors. Other data demonstrated that early infant MC is cost‐saving to health systems. Conclusions Arguments opposing MC are supported mostly by low‐quality evidence and opinion, and are contradicted by strong scientific evidence.
