Some sociodemographic and diagnostic characteristics of military patients treated in the Department of Medical Oncology, Gülhane Military Medical Academy.

Today, chronic diseases have increased importance. Cancer, for which 10 million new cases are diagnosed around the world each year, is in the lead of such diseases. This study included military personnel with cancer who applied to the Department of Medical Oncology, Gülhane Military Medical Academy, in the period between 1998 and 2003, and it aims to describe some sociodemographic and diagnostic characteristics of the patients. The total number of cases was 938, which included both active duty and retired military personnel with diagnoses of cancer who were given medical care between 1998 and 2003 in the Department of Medical Oncology. For the study group, the five most common diagnoses were lung cancer, colorectal cancer, testicular cancer, non-Hodgkin's lymphoma, and Hodgkin's disease. Although the first three diagnoses among officers were lung cancer, testicular cancer, and Hodgkin's disease, those among retired officers were colorectal cancer, lung cancer, and prostate cancer. Among noncommissioned officers, the first three diagnoses were colorectal cancer, testicular cancer, and Hodgkin's disease for active duty patients and lung cancer, colorectal cancer, and gastric cancer for retired patients. In the group of privates, testicular cancer, Hodgkin's disease, and non-Hodgkin's lymphoma were the first three diagnoses. When we consider the characteristics of cancers, such as high costs of treatment, loss of manpower, and high mortality rates, prevention of cancers and early diagnosis are very important. Because the frequent types of cancers differed for groups according to age and occupation, those characteristics should be considered when cancer screening programs are being developed for the Armed Forces.

Correlation between hyperbaric oxygen exposure pressures and oxidative parameters in rat lung, brain, and erythrocytes.

OBJECTIVES: The oxygen toxicity risk of hyperbaric oxygen (HBO) treatment has long been of interest. However, there are no comprehensive articles describing the relationship between HBO protocols and oxidative parameters used clinically. The purpose of this study was to determine the effects of various HBO pressure modalities on the oxidative values of rat lung, brain, and erythrocytes. DESIGN AND METHODS: A total of 64 male Sprague-Dawley rats was randomly divided into 7 groups. Group A was used as a control. Groups C to G were subjected to 100% oxygen at a pressure of 1, 1.5, 2, 2.5, and 3 ATA (atmosphere absolute), respectively, for 2 h. Group B was exposed to normal atmospheric air at 3 ATA for the same duration. The rat's lung, brain, and blood were taken immediately after the exposure and thiobarbituric acid reactive substances (TBARS) and superoxide dismutase (SOD) levels were determined. RESULTS: Both TBARS levels and SOD activity increased concordantly with the pressure increase. Although a statistically significant change in TBARS levels started from 100% oxygen exposure at 1 ATA (normobaric), SOD activity was affected after 2 ATA. A significant correlation exists between exposure pressure and the aforementioned parameters. Ambient air exposure at 3 ATA did not affect any parameters besides the brain TBARS levels. CONCLUSIONS: It is clear that HBO exposure causes oxidative stress. The main reason for this effect seems to be exposure to pure oxygen, since pure high pressure has no significant effect on the aforementioned parameters. However, clinicians should use as low pressures as possible since all oxidative parameters appear to be directly proportional to the extent of HBO exposure.

How medical students use the computer and Internet at a Turkish military medical school.

The aim of this study was to determine how medical students use the computer and World Wide Web at a Turkish military medical school and to discuss characteristics related to this computer use. The study was conducted in 2003 in the Department of Public Health at the Gulhane Military Medical School in Ankara, Turkey. A survey developed by the authors was distributed to 508 students, after pretest. Responses were analyzed statistically by using a computer. Most of the students (86.4%) could access a computer and the Internet and all of the computers that were used by students had Internet connections, and a small group (8.9%) had owned their own computers. One-half of the students use notes provided by attending stuff and textbooks as assistant resources for their studies. The most common usage of computers was connecting to the Internet (91.9%), and the most common use of the Internet was e-mail communication (81.6%). The most preferred site category for daily visit was newspaper sites (62.8%). Approximately 44.1% of students visited medical sites when they were surfing. Also, there was a negative correlation between school performance and the time spent for computer and Internet use (-0.056 and -0.034, respectively). It was observed that medical students used the computer and Internet essentially for nonmedical purposes. To encourage students to use the computer and Internet for medical purposes, tutors should use the computer and Internet during their teaching activities, and software companies should produce assistant applications for medical students. Also, medical schools should build interactive World Wide Web sites, e-mail groups, discussion boards, and study areas for medical students.
