Efectividad del té verde en el tratamiento de periodontitis crónica / Greentea effectiveness in chronic periodontitis treatment

El té verde ha mostrado un amplio rango de efectos fisiológicos y farmacológicos. En los últimos años se han llevado a cabo estudios sistemáticos principalmente por investigadores japoneses en los cuales se evidenciaron las acciones antimicrobianas útiles y variadas que poseen los extractos de té. El objetivo de este trabajo fue determinar, mediante el uso de registros cuantificables, la efectividad clínica y microbiológica del té verde en el tratamiento de las periodontitis crónicas. Fueron evaluados 50 pacientes de ambos sexos, con diagnóstico de periodontitis crónica y con un mínimo de tres bolsas periodontales por cuadrante con profundidad de sondaje ≥ 5 mmy pérdida de inserción ≥ 2 mm por proximal, que concurrieron a la Cátedra de Periodoncia de la Facultad de Odontología de la Universidad Nacional de Rosario, Argentina. Las variables clínicas consideradas fueron Indice Gingival (Loe y Silness, 1963), Sangrado al Sondaje (Val del Verden, 1979), Profundidad de sondaje con sonda milimetrada tipo Marquis y Nivel de inserción epitelial vertical. Para determinar la eficacia microbiológica del tratamiento se extrajeron muestras de placa subgingival con conos de papel estéril del fondo de las bolsas periodontales. Se sembró en medio de Agar Schlaeder – sangre enriquecido con 1% de hemina y vitamina K en atmósfera anaeróbica a 37°C durante 5 días. La tipificación fue realizada con el método comercial semi-automatizado Api 20 A Biomerieux – France. El uso de extracto de té verde asociado a la terapia periodontal mecánica ha sido sensiblemente eficaz en la reversión de estas variables en el tratamiento de la periodontitis crónica, si bien su uso asociado o no al raspaje y alisamiento radicular no mostró diferencias significativas respecto del raspaje y alisamiento como monoterapia para el control de la flora anaeróbica en esta patología (AU)

Green tea has been shown to have a wide range of physiological and pharmacological effects. In recent years, systematic studies performed mainly by Japanese researchers have evidenced the wide range of very useful antimicrobial properties of tea extracts. The aim of the present study was to quantitatively evaluate the clinical and microbiological efficacy of green tea in the treatment of chronic periodontitis. Fifty male and female patients who attended the Department of Periodontics, Faculty of Dentistry, National University of Rosario, Argentina, and had been diagnosed with chronic periodontitis were included in the study. The selected patients had at least 3 periodontal pockets per quadrant, depth on probing ≥ 5 mm and proximal attachment loss ≥ 2 mm. The clinical endpoints assessed were Gingival Index (Loe y Silness, 1963), Bleeding on Probing (Val del Verden, 1979), Depth on Probing with a Marquis type probe and Level of Vertical Epithelial Attachment. Samples of subgingival plaque were obtained with sterile paper cones from the bottom of the periodontal pockets to evaluate microbiological efficacy. The samples were seeded in Agar Schlaeder medium – blood enriched with 1% hemine and vitamin K in anaerobiosis at 37°C for 5 days. Typification was performed employing the commercial semi-automatic method Api 20 A Biomerieux – France. The use of green tea extract coupled to mechanical periodontal therapy for chronic periodontitis was efficient in controlling these variables. However, when it was used coupled to root scaling and planing it did not significantly improve the control of anaerobic flora as compared to scaling and planing used alone (AU)

[Intestinal intussusception: easy diagnosis in the 21st Century? Outcome of five years experiences]. / Invaginazione intestinale: una diagnosi facile nel 21 degrees secolo? Outcome degli ultimi 5 anni.

UNLABELLED: Intussusception is an entity well codify in pediatric surgery, with guidelines well defined since years in terms of imaging and procedures. MATERIAL: From January '99 to Dec. '03, 25 children were admitted to the Department of Pediatric Surgery of the Children's Hospital of Milan. All the aspects related to the pathology have been evaluated in the study. RESULTS: 25 patients have been studied. 23/25 presented severe pain, 19/25 normal bowel movements in the last 3 hours and in 9/25 a mass were detected at clinical examination.19/25 were submitted to laparotomy after failure of reduction through barium enema, and in 17/19 a manual reduction were performed. Only 2 patients required a bowel resection with primary anastomosis. The analysis of the delay of diagnosis, the delta-T between beginning of the symptoms and first medical evaluation was of 16,23 h. (3-72), and the delta-T between the first evaluation and diagnosis was 18,7 h. The interval between diagnosis and surgery was of 4,3. CONCLUSION: Authors believe that intussusception still represent a challenge for medical and surgical emergency team, supported by the data in literature. Imaging procedures must not be constricted in case of minimal suspicions of intestinal intussusception.
