ABSTRACT Adverse effects may occur in 10.4% of patients receiving terbinafine therapy, with cutaneous reactions in 2.7%. We describe the development of psoriasis in four patients who took oral terbinafine. Two patients had plaque-type psoriasis that flared 12 and 17 days, respectively, after starting terbinafine. Another patient developed pustular-type psoriasis de novo after 27 days of terbinafine therapy. The fourth patient was a psoriatic with stable plaque disease who experienced a pustular flare after taking terbinafine for 21 days. We are aware of only one report in the literature in which a patient developed pustular psoriasis de novo after 5 days of terbinafine therapy. In all patients the psoriasis cleared or lessened after discontinuation of terbinafine and institution of antipsoriatic therapy.

    ABSTRACT: Onychomycosis is a common condition in the adult population. It has been reported to be more prevalent in association with some specific diseases including psoriasis. This study using combined histomycology and cultures was performed on nail clippings collected from thickened dystrophic toenails in 233 eligible psoriatic patients. Onychopathies associated with psoriasis were more numerous in men. Their prevalence increased up to the age of 40 and remained stable thereafter. A total of 42/233 cases were diagnosed as onychomycoses. These infections were more prevalent in middle-aged men. The identified infectious agents (35/42 cases) frequently corresponded to dermatophytes, but Candida albicans was also implicated, particularly in women.

    ABSTRACT: It remains unclear whether or not creating gaps in planted forests can increase the plant species composition, structure, and biodiversity, and also whether it can be helpful for restoring planted forests (to a more natural state). Based on a comparison of species composition and structure among forest patches, small gaps (4–25m2), medium gaps (25–150m2) and large gaps (150–450m2), we found that (1) creating gaps enhanced vascular plant diversity. Both the species richness and Shannon diversity indices of small, medium and large gaps were significantly higher than in the understory. The pattern of increasing diversity of vascular plants with gap creation could be partly attributed to the emergence of novel shade intolerant species in gaps. (2) Creating gaps favored the colonization and regeneration of native species. Gap size influenced not only the emergence and density of individuals of different species, but also the emergence of different life form types. Small gaps promoted the regeneration of some shrub species, such as Ostryopsis davidiana, Rosa hugonis, and Forsythia suspense, leading to these species becoming canopy dominants early on in succession. The medium and large gaps favored the growth of tree species, such as Populus davidiana and Betula platyphylla (early successional stage), and Quercus liaotungensis and Pinus tabulaeformis (later successional phase). (3) The canonical correspondence analysis showed that plant species composition and distribution were mainly influenced by gap size and slope aspect, and that the recorded plant species could be divided into three life forms (trees, shrubs and herbs) on the biplot diagram. (4) Finally, creating gaps provided opportunities not only for native pioneer species in the early successional stage, but also for climatic climax species to grow to canopy dominants in later successional phases, suggesting that a more natural forest will develop with plant succession. Gap size plays an important role in plant regeneration, and it could be used to produce desired successional communities in near natural management for planted forests.

    ABSTRACT: Ein 65-jähriger Patient stellte sich mit umschriebenen graubraunen Pigmentierungen im Bereich des Gesichts vor. Vorangegangen war eine Onychomykosetherapie mit Terbinafin, unter welcher sich erste Hautveränderungen bereits nach 4 Wochen manifestierten. Weitere Medikamente nahm der ansonsten gesunde Patient nicht ein. Histologisch zeigten sich im oberen und tiefen Corium Makrophagen mit feinen, melaninartig reagierenden Pigmentgranula. In der Literatur sind als kutane Nebenwirkungen einer Therapie mit Terbinafin insbesondere urtikarielle und ekzematöse Hautveränderungen beschrieben, seltener können auch schwere kutane Unverträglichkeitsreaktionen auftreten. Hyperpigmentierungen als Folge einer Therapie mit Terfenadin sind bislang nicht beschrieben worden. Klinisch ähnliche graubraune Hyperpigmentierungen waren unter der Therapie mit Minozyklin, Amiodaron, trizyklischen Antidepressiva oder Schwermetallen zu beobachten. Dieser Fallbericht zeigt, dass an eine medikamentenbedingte Hyperpigmentierungen auch gedacht werden sollte, wenn für diese Nebenwirkung nicht bekannte Pharmaka eingenommen werden.
