One Year Clinical Evaluation of White Spot Lesions with Newly Introduced Resin Modified Glass-Ionomer in Comparison to Resin Infiltration in Anterior Teeth: a split mouth randomized controlled clinical trial from Egypt / Avaliação clínica de um ano de lesões de mancha branca com iônomo de vidro modificado por resina recentemente introduzido em comparação à infiltração de resina em dentes anteriores: um ensaio clínico controlado randomizado de boca dividida do Egito

Objective: to compare the clinical performance of newly introduced resin modified glass ionomer varnish (Clinpro™ XT) versus resin infiltration in treatment of post-orthodontic white spot lesions. Material and Methods: Six participants (70 teeth) were enrolled with post-orthodontic white spot lesions. Randomization was performed according to patient selection for the sealed envelope containing which half will receive the control (resin infiltration (ICON, DMG) and the other will receive the intervention (resin modified glass-ionomer cement varnish (Clinpro™ XT, 3M)). Follow up was done after 1 day, 1 week, 1 month, and 3 months, 6 months and 12 months. The color was assessed by spectrophotometer while the degree of demineralization was measured by Diagnodent pen 2910. Patient satisfaction was assessed using (VAS) Visual analogue scale Results:Regarding color change, significant improvement in lightness for ICON group, while Clinpro™ XT group, the change was insignificant. The demineralization data revealed significant decrease in demineralization with resin infiltration after immediate application. Clinpro™ XT showed also significant decrease after immediate assessment and significant increase in demineralization in 6 and 12 months. Conclusion: Resin infiltration can be considered more as an alternative treatment rather than fluoride varnish. Clinpro™ XTis considered as a preventive protocol, provided that renewal application is needed after 3 months (AU)

Objetivo: comparar o desempenho clínico do recém-introduzido verniz de ionômero de vidro modificado por resina (Clinpro ™ XT) com a infiltração de resina no tratamento de lesões de manchas brancas pós-ortodônticas. Material e Métodos: Seis participantes (70 dentes) foram inscritos com lesões pós-ortodônticas de manchas brancas. A randomização foi realizada de acordo com a seleção do paciente para o envelope lacrado contendo qual metade receberá o controle (infiltração de resina (ICON, DMG) e a outra metade receberá a intervenção (verniz de cimento de ionômero de vidro modificado por resina (Clinpro ™ XT, 3M)). O acompanhamento foi feito após 1 dia, 1 semana, 1 mês e 3 meses, 6 meses e 12 meses. A cor foi avaliada por espectrofotômetro, enquanto o grau de desmineralização foi medido pela caneta Diagnodent 2910. A satisfação do paciente foi avaliada usando (VAS) Escala visual analógica. Resultados: Em relação à mudança de cor, houve uma melhora significativa na luminosidade para o grupo ICON, enquanto o grupo Clinpro ™ XT, a mudança foi insignificante. Os dados de desmineralização revelaram diminuição significativa da desmineralização com infiltração de resina após a aplicação imediata. O grupo Clinpro ™ XT também mostrou diminuição significativa após avaliação imediata e aumento significativo na desmineralização em 6 e 12 meses. Conclusão: A infiltração de resina pode ser considerada mais como uma alternativa de tratamento do que o verniz fluoretado. O Clinpro ™ XT é considerado um protocolo preventivo, uma vez que a renovação é necessária após 3 meses. (AU)

Impact of Prophylactic Bilateral Central Lymph Nodes Dissection in Patients with Papillary Thyroid Carcinoma; Short Term Outcome

Background:Papillary thyroid carcinoma is the most common thyroid carcinoma. There is a debate on prophylactic removal of central lymph nodes. Some authors advise it to avoid recurrence while other investigators condemn it due to its higher risk of recurrent laryngeal nerve injury and/or hypoparathyroidism. Aim of the Work:The aim of this study was to evaluate the safety and morbidity of central lymph nodes dissection during total thyroidectomy in the management of patients with papillary thyroid carcinoma. Patients and Methods: Twelve patients were confirmed by histopathological evaluation to have papillary thyroid examination. Total thyroidectomy was done through transverse neck incision followed by removal of bilateral central group of lymph nodes. Patients were examined postoperatively for recurrent laryngeal nerve injury or hypoparathyroidism. Follow up was done 6 months later with neck ultrasonography,thyroglobulin and antithyroglobulin antibodies. Results: Thirty four percent of the studied cases proved to have lymph nodes metastasis. temporary hypocalcemia occurred in only one patient in this study and was temporary. Recurrent laryngeal nerve affection happened in 17% of the studied cases and was reversible by medical treatment. No evidence of recurrence happened in the first 6 months after operation. Conclusion:The risk of postoperative recurrent laryngeal nerve injury or hypoparathyroidism is minimal after prophylactic CLND. Postoperative hypocalcemia and recurrent laryngeal nerve injury are usually reversible

Cytotoxic activity and phytochemical analysis of Arum palaestinum Boiss

Objective: To evaluate the in vitro cytotoxic activity of the fractionated extract as well as isolated compounds of Arum palaestinum Boiss. ( A. palaestinum) (black calla lily), and to identify the volatile components which may be responsible for the potential antitumor activity. Methods: A. palaestinum was collected from its natural habitats and subjected to phytochemical analysis for separation of pure compounds. In vitro cytotoxic activity was investigated against four human carcinoma cell lines Hep2, HeLa, HepG2 and MCF7 for the fractionated extract and isolated compounds. While, the diethyl ether fraction was subjected to GC-MS analysis as it exhibited the most potent cytotoxic effect to evaluate the active constituents responsible for the cytotoxic activities. Results: Four flavonoid compounds were isolated (luteolin, chrysoeriol, isoorientin, isovitexin) from the diethyl ether and ethyl acetate. The extracts and the pure isolated compounds showed a significant high antiproliferative activity against all investigated cell lines. The GC-MS analysis revealed the separation and identification of 15 compounds representing 95.01% of the extract and belonging to different groups of chemical compounds. Conclusions: The present study is considered to be the first report on the cytotoxic activities carried out on different selected fractions and pure compounds of A. palaestinum to provide evidences for its strong antitumor activities. In addition, chrysoeriol and isovitexin compounds were isolated for the first time from the studied taxa.

A case of cellulitis of the hands caused by a predatory bird attack

Many species have been drastically affected by rapid urbanization. Harris's hawks from their natural habitat of open spaces and a supply of rodents, lizards and other small prey have been forced to change their natural environment adapting to living in open spaces in sub- and peri-urban areas. Specific areas include playgrounds, parks and school courtyards. The migration of this predatory species into these areas poses a risk to individuals, and especially the children are often attacked by claws, talons and beaks intentionally or as collateral damage while attacking rodent prey. In addition, the diverse micro-organisms harbored in the beaks and talons can result in wound infections, presenting a challenge to clinical management. Here we would like to present a case of an 80-year-old man with cellulitis of both hands after sustaining minor injuries from the talons of a Harris's hawk and review the management options. We would also like to draw attention to the matter that, even though previously a rarity, more cases of injuries caused by birds of prey may be seen in hospital settings.

Clinical impacts of oral gastrografin follow through in adhesive small bowel obstruction [ASBO]. [a prospective randomized study]

Many studies have shown that Gastrografin can be used for diagnosis of adhesive small bowel obstruction [ASBO] and for assessing the need for surgical intervention .However; several the studies have reported conflicting results. Therefore the aim of this study is to assess the diagnostic and therapeutic effect of Gastrografin in ASBO. Altogether 110 patients with ASBO were randomized into control and Gastrografin groups. In the Gastrografin group, 100 ml of the dye was administered through a nasogastric tube. Obstruction was considered complete if the contrast failed to reach the colon on the 24-hour film. Patients with Gastrografin in the colon within 24 hours after dye administration were considered as partially obstructed and were submitted to non operative treatment. The patients were operated on if they developed signs of strangulation or failed to improve within 48 hours. The overall operative rate 14.5% in Gastrografin group versus 34.5% in control group: P = 0.04 .The time from admission to resolution of symptoms was significantly lower in Gastrografin group [19.5 vs. 42.6 hours: P = 0.001] and the length of hospital stay shorter in Gastrografin group [3.8 vs. 6.9 days 0.002] and in non operative patients [3.1 vs. 5.1 days]. Sensitivity, specificity, positive predictive value and negative predictive value for Gastrogrqfin follow-through as an indicator for operative treatment of ASBO were 87.5%, 100%, 100%, and 97.9% respectively. Oral Gastrografin helps in the management of ASBO. Oral Gastrografin is safe and reduces the operative rate and time of resolution as well as hospital stay

Early oral feeding in patients undergoing elective colonic anastomosis

Recent evidence seems to indicate that immediate postoperative feeding if feasible is safe after either laparoscopic surgery or laparotomy. This study is done to assess the safety, outcome of early oral feeding and shows factors affecting early postoperative feeding after colorectal procedures. Between June 2005 and April 2008, 120 consecutive patients underwent elective colonic anastomosis were then randomized into 2 groups. Early feeding group began fluid on the first postoperative day and regular feeding group were managed in the traditional way- nothing by mouth until the resolution of the ileus. The majority of patients [75%] tolerated the early feeding. The time to first passage of flatus [3.3 +/- 0.9 d vs. 4.2 +/- 1.2 d] and stool [4.1 +/- 1.2 d vs 4.9 +/- 1.2 d] were significantly sooner in group 1. Hospital stay is significantly shorter in early feeding group [4.2 +/- 0.2 d vs. 6.9 +/- 0.5 d]. Operative time and amount of blood loss had a significant impact on tolerability of early feeding while age, gender, type of operation, and previous abdominal operation had no significant impact. Early oral feeding after colorectal surgery is safe, tolerated by the majority of patients. Operative time and amount of blood loss has impact on the tolerability of early feeding

Clinical impacts of oral gastrografin follow through in adhesive small bowel obstruction [SBO]

Many published studies have shown that Gastrografin can be used for diagnosis post operative acute small bowel obstruction [ASBO] and assessing the need for surgical intervention. However, the studies have reported conflicting results hence the aim of our study to test this hypothesis. Altogather 100 patients with 117 episodes of ASBO were randomized into control and gastrografin groups in a double blinded fashion. Eight episodes in eight patients were excluded due to protocol violation. In Gastrografin group, 100 ml of the dye administered through a nasogastric tube and complete-obstruction has been considered if the contrast failed to reach the colon on the 24-hour film .Patients were operated on only if they developed signs of strangulation or failed to improve within 48 hours. Gasrografin group showed a significant decrease of both the time between admission and operation [P = 0.001] and that of hospital stay [P = 0.000]. The need for surgery was reduced but statistically insignificant [P = 0.225]. Oral Gastrografin helps in the management of ASBO
