Abstract:

Objectives:

A prospective randomized study designed to compare results of intra-operative applications of povidone-iodine with those of hydrogen peroxide during surgery for hydatid cysts.

Methods:

This study includes 160 patients with pulmonary and/or hepatic univesicular hydatid cysts. Group A consisted of 80 patients for whom we used hydrogen peroxide; Group B consisted of 80 patients for whom we used povidoneiodine. Each cyst was examined both macroscopically and microscopically to identify effects of the used scolicidal agent on the wall. Post-operatively, patients received Albendazole as a scolicidal drug for one year. Follow up times ranged between 48 and 84 months. Chest x-rays and abdominal ultrasound examinations were performed every six months to detect any recurrences.

Results:

There was no peri-operative mortality in either of the two groups. Group A: one case of postoperative prolonged air-leak and two cases of wound infection. No recurrences were reported. Mean hospital stay was 5.5 ± 1.1 days. Group B: two cases of prolonged air leak, three cases of persistent cough and hemoptysis, one developing broncho-pleural fistula that healed (air leak ceased after 19 days), two cases of wound infection, one had subphrenic abscess, nine cases of recurrences, one on the diaphragmatic pleura, two with deep chest wall cysts at sites of thoracostomy tubes, four intraperitonial recurrences, two in the same liver lobe. Recurrences occurred in 11% of the subjects (9/80; p value = 0.028). Mean hospital stay was 9.6 ±1.5 days.

On histologic examination of Group A, the cyst wall lost its integrity, luster and viability and became friable. In Group B the cyst wall maintained most of its luster, integrity, viability and did not become friable.

Conclusions:

Hydrogen peroxide is a more effective and safer scolicidal drug than povidone-iodine as shown by the differences in mean duration of hospital stay and postoperative recurrence rate significance.

"It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor."


Jacques Descotes
(Centre Antipoison-Centre de Pharmacovigilance, France)

"Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community."


Patrice Talaga

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."


Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."


Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."


Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."


Richard Reithinger
(Westat, USA)

"Not only do open access journals greatly improve the access to high quality information for scientists in the developing world, it also provides extra exposure for our papers."

"Open Access 'Chemistry' Journals allow the dissemination of knowledge at your finger tips without paying for the scientific content."


Sean L. Kitson
(Almac Sciences, Northern Ireland)

"In principle, all scientific journals should have open access, as should be science itself. Open access journals are very helpful for students, researchers and the general public including people from institutions which do not have library or cannot afford to subscribe scientific journals. The articles are high standard and cover a wide area."


Hubert Wolterbeek
(Delft University of Technology, The Netherlands)

"The widest possible diffusion of information is critical for the advancement of science. In this perspective, open access journals are instrumental in fostering researches and achievements."


Alessandro Laviano
(Sapienza - University of Rome, Italy)

"Open access journals are very useful for all scientists as they can have quick information in the different fields of science."


Philippe Hernigou
(Paris University, France)

"There are many scientists who can not afford the rather expensive subscriptions to scientific journals. Open access journals offer a good alternative for free access to good quality scientific information."


Fidel Toldrá
(Instituto de Agroquimica y Tecnologia de Alimentos, Spain)

"Open access journals have become a fundamental tool for students, researchers, patients and the general public. Many people from institutions which do not have library or cannot afford to subscribe scientific journals benefit of them on a daily basis. The articles are among the best and cover most scientific areas."


M. Bendandi
(University Clinic of Navarre, Spain)

"These journals provide researchers with a platform for rapid, open access scientific communication. The articles are of high quality and broad scope."


Peter Chiba
(University of Vienna, Austria)

"Open access journals are probably one of the most important contributions to promote and diffuse science worldwide."


Jaime Sampaio
(University of Trás-os-Montes e Alto Douro, Portugal)

"Open access journals make up a new and rather revolutionary way to scientific publication. This option opens several quite interesting possibilities to disseminate openly and freely new knowledge and even to facilitate interpersonal communication among scientists."


Eduardo A. Castro
(INIFTA, Argentina)

"Open access journals are freely available online throughout the world, for you to read, download, copy, distribute, and use. The articles published in the open access journals are high quality and cover a wide range of fields."


Kenji Hashimoto
(Chiba University, Japan)

"Open Access journals offer an innovative and efficient way of publication for academics and professionals in a wide range of disciplines. The papers published are of high quality after rigorous peer review and they are Indexed in: major international databases. I read Open Access journals to keep abreast of the recent development in my field of study."
