Research progress on occupational exposure and protection from acquired immunodeficiency syndrome in stomatological departments / 华西口腔医学杂志

Acquired immunodeficiency syndrome (AIDS) is an infectious disease caused by human immunodeficiency virus (HIV). The disease is highly infectious, quickly spreads, and has a high fatality rate. Hence, it is a major concern in public health, and an important subject in the prevention and treatment of infectious diseases. The medical staff of stomatological departments, which handle the diagnosis and treatment of oral diseases, are at particularly high risk of occupational exposure to HIV/AIDS. This study summarizes the HIV/AIDS epidemic status, disease transmission routes, oral lesions in HIV/AIDS patients, occupational exposure, and occupational protection in stomatological departments.

Influences of water supply sources of dental comprehensive treatment platform on intra-pipeline water quality / 医疗卫生装备

Objective To investigate the impacts of water supply on water quality in the pipeline of the dental comprehensive treatment platform to contribute to pollution control.Methods Totally 8 platforms from the stomatological department underwent 2-a detection and tracing.The water sources included tap water,distilled water and filtered water,and the discharge water went through sampling and bacteriological analysis before and after disinfection.Results The mean numbers of colonies by tap water,distilled water and filtered water were (472±385),(380±372) and (446±382) cfu/ml respectively,and the qualification rates by tap water,distilled water and filtered water were 33.3％,45.8％ and 37.5％ respectively.All the colonies numbers were limited within 0 and 60 cfu/ml with the qualification rate being 100％ after disinfection.Conclusion Water source cannot relieve bacterial infection effectively,and disinfection eliminates bacteria and improves water quality in the pipeline of the dental comprehensive treatment platform.

Eficacia del extracto fluido de Vimang® en el tratamiento de pacientes con alveolitis / Effectiveness of the American extract of Vimang® in the treatment of patients with alveolitis

Se realizó un ensayo clínico de fase III en 118 pacientes con alveolitis, atendidos en la consulta estomatológica del Hospital General Docente "Dr. Juan Bruno Zayas Alfonso" de Santiago de Cuba, para evaluar la eficacia del extracto fluido de Vimang® en el tratamiento de ellos. La muestra se dividió en 2 grupos (experimental y control), distribuidos aleatoriamente; los integrantes del primero, tratados con el mencionado extracto; y los del segundo, con Alvogyl. Los resultados del estudio fueron validados mediante el estadígrafo de Ji al cuadrado. Se concluye que el extracto fluido de Vimang® fue eficaz para eliminar la alveolitis en menor tiempo y sin reacciones adversas, por lo cual se recomendó generalizar su uso.

The sample was divided in 2 groups (experimental and control group), randomly distributed; the members of the first one was treated with the aforementioned extract; and those of the second group with Alvogyl. The results of the study were validated by means of the X² test. It is concluded that the fluid extract of Vimang® was effective to eliminate alveolitis in shorter period and without adverse reactions, reason why it was recommended to generalize its use.

Manifestaciones bucales del liquen plano / Oral manifestations of the lichen planus

Se efectuó un estudio descriptivo y transversal de 102 pacientes con liquen plano bucal, atendidos en la consulta estomatológica del Policlínico de Especialidades del Hospital Provincial Docente Clinicoquirúrgico "Saturnino Lora Torres" de Santiago de Cuba, a fin de evaluar las alteraciones celulares epiteliales, así como relacionarlas con el diagnóstico y las formas clínicas de dicha enfermedad. A los afectados se les realizó biopsia para obtener las muestras de tejido lesionado, las cuales fueron fijadas y procesadas con la técnica de inclusión en parafina. Esta afección tuvo mayor frecuencia después de la segunda década de la vida y prevaleció en los pacientes de piel blanca. La región topográfica más afectada fue la mucosa de carrillo. Los hallazgos más relevantes en el estudio microscópico correspondieron al infiltrado inflamatorio en banda y la degeneración vacuolizante de la capa basal del epitelio.

A descriptive and cross-sectional study of 102 patients with oral lichen planus, assisted in the stomatological department from the Specialties Polyclinic of "Saturnino Lora Torres" Clinical Surgical Teaching Provincial Hospital in Santiago de Cuba was carried out in order to evaluate the epithelial cellular alterations, as well as to relate them with the diagnosis and the clinical forms of this disease. Biopsies were carried out to those affected to obtain the samples of damaged tissue, which were fixed and processed with the paraffin inclusion technique. This affection had higher frequency after the second decade of life and it prevailed in the white skinned patients. The most affected topographical region was the cheek mucous. The most relevant findings in the microscopic study corresponded to the band-like inflammatory infiltrate and the vacuolizing degeneration of the epithelium basal layer.
