Pityriasis versicolor‐A Study of 200 Cases in a Tropical Skin Clinic: Pityriasis versicolor — Eine Untersuchung an 200 Fällen in einer tropischen Hautklinik

Summary: A study of pityriasis versicolor was done in a total of 100 each of males and females. Incidence of the disease was equally high during summer (April) and winter (October). The adolescents were affected mainly. General hygiene showed no relevance to the disease. The lesions commonly occurred over the upper trunk and face. Hands, feet and ears were rarely involved. Achromic, chromic and a combination of both the varieties were equally common. Follicular and palpable lesions were not uncommon. Various other clinical varieties have been observed and described. Acne vulgaris and dermatophytoses were the common associated dermatoses. Striae distensae was seen frequently, especially in young girls. Wet mount in KOH was positive in all cases. A definite correlation of sebum and probably androgens to the disease has been observed and discussed.

Histological Study in Tinea Capitis: Histologische Untersuchungen bei Tinea capitis

Summary: Histological studies in 50 cases of tinea capitis caused mainly by Trichophyton violaceum have shown three distinct varieties which correlated with their clinical types. Findings in the present and previous studies on tinea capitis correlate a higher incidence of the disease in noninflammatory types and a lower incidence in the inflammatory types. Existence of two different subspecies of T. violaceum is surmised from the present study.

Growth Pattern and Constituents of Dermatophytes in Varied Substrates: Wachstumsverhalten und chemische Zusammensetzung von Dermatophyten auf verschiedene Nährsubstanzen

Summary: Growth pattern of certain dermatophytes in varied substrates with their biochemical constituents have been studied. This study was carried out with isolates obtained from patients of Madras, India.

Entomophthoromycosis basidiobolae‐Successfully Treated with KI

Summary: Entomophthoromycosis basidiobolae in a 2½ year old female child is described with clinical, mycological and histopathological findings. Oral potassium iodide resolved the condition successfully.

Genetic Ichthyosis and Trichophyton rubrum Infection in Infants: Genetische Ichthyosen und Trichophyton‐rubrum‐Infektionen bei kleinen Kindern

Summary: Extensive and chronic tinea glabrosa in one infant and a chronic tinea manuum and tinea unguium in another due to Trichophyton rubrum infection have been described. X‐Linked ichthyosis vulgaris in the former and ichthyosis vulgaris (dominant) in the latter case were the associated conditions. The slow epidermal turnover and slow nail growth are the probable predisposing factors in these infants. It is emphasised that genetic ichthyotic disorders are more prone for T. rubrum infection.

Amino Acids in Dermatophytes under Varied Substrates: Aminosäuren in Dermatophyten auf verschiedenen Nährsubstraten

Summary: Amino acid patterns in the mycelia of 9 dermatophytes have been studied on minimal and complex media. A greater number of amino acids was detected in the mycelia of dermatophytes grown in complex medium than those grown in various minimal media. Their preference for protein and complex media is emphasised.

Sporotrichosis‐Like Mycetoma caused by Actinomadura Madurae

Summary: Actinomycotic mycetoma caused by Actinomadura madurae has been described with sporotrichosis like distribution along the regional lymphatic drainage. Complete remission occurred in 3 years with oral tetracycline.

Giant Cell Granuloma in Trichophyton rubrum Infection/Riesenzellgranulom bei Trichophyton rubrum Infektion

Summary: A case of giant cell granuloma caused by Trichophyton rubrum is reported. Clinically the fungus had elicited skin coloured flat topped papules and plaques. Fungal filaments were absent in these areas histologically though skin scales revealed mycelia in KOH mount and grew T. rubrum. The histological findings suggest that histiocytes and plasma cells were mainly involved in the defence against T. rubrum infection in this case.
