Intractable epilepsy and craniocerebral trauma: analysis of 163 patients with blunt and penetrating head injuries sustained in war.

Post-traumatic epileptic seizure is a common complication of brain trauma including military injuries. We present clinical characteristics and correlates of post-traumatic epilepsy in 163 head-injured veterans suffering from intractable epilepsy due to blunt or penetrating head injuries sustained during the Iraq-Iran war. The medical records of 163 war veterans who were admitted by the Epilepsy Department of the Shefa Neuroscience Center between 2005 and 2009 were retrospectively reviewed. The mean follow-up period after developing epilepsy was 17.2 years. The time interval between the trauma and the first seizure was shorter and the seizure frequency was higher in epileptic patients suffering from penetrating head trauma. There was no difference in seizure type between epileptic patients traumatised by blunt or penetrating injury. Patients with seizure frequency of more than 30 per month mostly had simple partial seizure. Frontal and parietal semiologies were observed more frequently in patients with penetrating trauma, whereas patients with blunt trauma showed a higher temporal semiology. The most common brain lesion observed by CT scan was encephalomalacia followed by porencephaly and focal atrophy. There was no association between intracerebral retained fragments and different characteristic features of epilepsy. Patients with military brain injury carry a high risk of intractable post-traumatic epilepsy decades after their injury, and thus require a long-term medical follow-up.

Taxane-based regimens as a risk factor for chemotherapy-induced amenorrhea.

OBJECTIVE: The objective of our study was to show the impact of different chemotherapy regimens on the incidence of amenorrhea (chemotherapy-induced amenorrhea [CIA]) in premenopausal women of various ages with breast cancer. METHODS: This is a follow-up study of 226 premenopausal women with breast cancer who had received one of three chemotherapy regimens: conventional (cyclophosphamide/methotrexate/5-fluorouracil), anthracycline based, and anthracycline-taxane based. They were evaluated for the incidence of CIA in the follow-up clinic of the Iranian Center for Breast Cancer. A statistical analysis using SPSS software was performed, and logistic regression and Cox regression model were used to determine the risk factors for CIA. RESULTS: Of the 226 women with a median age of 40 years (range, 26-56 y) who participated in this study, 154 (68.1%) developed CIA. In 101 (65.6%) of these women, CIA was established. CIA was present in 52.5% of the women who had been treated with conventional regimens (cyclophosphamide/methotrexate/5-fluorouracil), 66.7% of the women who had been treated with anthracycline, and 78.7% of the women who had been treated with anthracycline-taxane. Therefore, the frequency of CIA was significantly higher in the taxane-based chemotherapy group than in the other groups (P = 0.015). Although a slightly higher incidence of CIA in women with hormone-insensitive tumors (estrogen receptor negative and progesterone receptor negative) versus hormone-sensitive tumors (estrogen receptor positive and progesterone receptor positive) who had been treated with combination regimens was observed, no statistically significant difference was found (P = 0.629). Of all of the risk factors that were evaluated in the study, anthracycline-taxane-based regimens (odds ratio, 4.059; 95% CI, 1.6-9.8) and age older than 40 years (odds ratio, 3.5; 95% CI, 1.9-6.6) were the most important factors in the development of CIA. CONCLUSIONS: The type of chemotherapy and the age of the woman at the onset of breast cancer are the most important risk factors in CIA. Taxane-based regimens induced more CIA than did other regimens.

Breast cancer in Iran: an epidemiological review.

Breast cancer is one of the most frequent malignancies among Iranian women, however; the epidemiological aspects of breast cancer among Iranian patients are uncertain. A literature review of the published articles from January 1998 to December 2005 was conducted using different search engines: MEDLINE, Scientific information data base of Academic Center for Education, Culture and Research, and over 2000 issues of 94 Persian medical journals. The headings "Breast Cancer,""Breast Tumor,""Breast Malignancy," and "Breast Carcinoma" were combined with the word "Iran" to execute the search. In all, 85 full papers were reviewed. These findings showed that participants ranged from 15 to 84 years old, with those 40-49 being the most prevalent. The incidence of breast cancer in women was 22 per 100,000. The prevalence in this same population was 120 per 100,000. Stage I was diagnosed in 18%, stage II in 57% and stage III in 25% of the cases. About 72% of the patients were diagnosed with a tumor over 2 cm. Sixty-three percent of the patients had lymph node involvement at the diagnostic time. Infiltrative ductal carcinoma was found to be the most common at 77% and lobular carcinoma the least at 5%. This review indicates that the epidemiological aspects of breast cancer in Iran are relatively well-studied. Shortcomings in study of its clinical aspects are evident and need to be a central part of upcoming investigations.
