Background: Melanin pigmentation of the gingiva occurs in allethnicities. Excessive pigmentation is an esthetic concern thathas increased awareness about depigmentation procedures. Thepurpose of the present study was to correlate the skin color andgender with the intensity and distribution of gingival melaninpigmentation in a group of South Indians for treatment strategies.Method: Two hundred m...

Anorexia nervosa is a psychiatric eating disorder with multisystemic complications. Several dermatologic abnormalities have been described but an association with purpura is rare. We report two cases of anorexia nervosa presenting with diffuse reticulate purpura over the trunk and extremities. The skin lesions resolved after the patients’ nutritional status improved. We emphasize that the diffu...

Treatment of HEp-2 cell cultures with highly purified human gamma interferon before infection resulted in the reduction of Chlamydia trachomatis (L2/434/Bu) infectious particle yield. Electron microscope studies showed that interferon did not affect chlamydial conversion to reticulate bodies but influenced the extent of maturation to elementary bodies. High interferon concentrations (greater th...

The usual assumption that species have evolved from a common ancestor by a simple branching process--where each branch is genetically isolated--has been challenged by the observation of frequent hybridization between species in natural populations. In fact, most plant species are thought to have hybrid origins. This reticulate pattern of species evolution has posed problems in the definition of...

Epidermolysis bullosa simplex with mottled pigmentation (EBS-MP) is a rare subtype of EBS. It characterized by non-cicatricial blisters, mainly at the distal extremities, and progressive hyperpigmentation. Its clinical features depend on age diagnosis, variations have been described even within family members. Blisters usually appear birth or in early infancy, tend to decrease age, only occasio...

Sera from 10 women with Chlamydia trachomatis culture positive cervicitis and sera from six men with C trachomatis positive non-gonococcal urethritis were studied for the presence of IgG, IgM, and IgA antibodies to polypeptides of C trachomatis elementary bodies and reticulate bodies using immunoblotting techniques. All the sera with IgG, IgM, or IgA immunoglobulins specific to C trachomatis re...

introduction: melanin pigmentation in the oral mucosa occurs as a result of several reasons one of which is smoking. cigarette smoke induces numerous side effects in the people who do not smoke, but are in the same environment. the aim of this study was to evaluate the role of parental smoking on pigmentation of their children's oral mucosa. materials and methods: this study was carried out as ...

statement of the problem: melanin pigmentation of the gingiva is a crucial esthetic problem. a variety of methods have been used for gingival depigmentation. purpose: the purpose of this study was to compare the results of two treatment modalities: scalpel technique and cryotherapy with liquid nitrogen in treatment of gingival pigmentation. materials and method: twenty patients with chief compl...
