Background&Objective: The proper treatment for early-stage Hodgkin’s disease is controversial. The purpose of this study was to evaluate the therapeutic outcomes of various treatment strategies in supradiaphragmatic clinical early-stage Hodgkin’s disease. Materials&Methods: This retrospective study reviewed the medical records of 105 eligible patients (49 stage I, 59 stage II) who were treated at radiotherapy- oncology departments of Qaem and Omid hospitals in Mashhad (Iran) from April 1995 to April 2000. 26 patients had B symptoms and 5 had large mediastinal mass. Treatment of patients consisted of chemotherapy alone (43 cases), radiotherapy alone (46 cases, 40 mantle and 6 Total nodal irradiation) and combined modality (16 cases). Survival rates were calculated by Kaplan- Meier model. Log-rank test was used to compare the survival profile between groups. Results: The median age of patients was 25 years with a male to female ratio of 1.56: 1. In comparison with radiotherapy only group, Primary chemotherapy and combined modality groups had significantly more cases with unfavorable factors such as B symptoms, Large mediastinal mass, ESR>40 and stage II. For chemotherapy, combined modality and radiotherapy groups the 5-year progression free survival was 72.5%, 82.5% and 56.2% (P<0.05) and the 5-year disease specific survival was 82.9%, 91.6% and 82.5% respectively. Conclusion: Despite having more cases with unfavorable factors, patients who underwent chemotherapy or combined treatment had lower relapse rates compared to radiotherapy only group. However, there was not a significant difference in 5-year disease specific survival rates between these groups.

Background and Objective: Critical illness diaphragmatic neuromyopathy are significant  causes of weakness, morbidity and prolong mechanical ventilation among critically ill patients under mechanical ventilation. It is important determine the true initial time of neuromyopathic changes associated with critically ventilated patients. Based on new electrodiagnostic studies, electrophysiological studies of diaphragm and phrenic nerve, as an important muscle and nerve in ventilation, compared with other evaluating methods, have specific importance. This study was done to evaluate of the diaphragmatic myopathy onset time among mechanically ventilated patients using electrophysiological method.

Materials and Methods: This descripvtive study was performed on 56 mechanically ventilated patients in intensive care unit without primary neuromuscular disease in Tabriz Imam Khomeini hospital in West of Iran between 2004-06 years. Electromyography (EMG) and nerve conduction velocity test were performed in the 4^th and then in 4 days intervals.

Results: In 56 patients EMG and NCV performed at 4 and 8 days after mechanical ventilation, none of them had any evidence in favor of diaphragmatic myopathy. During the course of study, EMG were done on 24 patients in 12^th days , that in three of them (12.5%), mild myopathy were reported. From 18 patients, considered in 16^th days, only five (31.25%) of them showed mild myopathy. From 10 (100%) reminder patients, in 20^th day, all of them had mild to moderate myopathy.

Conclusion: According to these results, minimum duration of the diaphragmatic weakness onset time in mechanically ventilated patients with diverse causes in general critical care ward were 12 days and increased with prolonged time of mechanical ventilation.

Background and Objective: Trauma is the most common cause of death in all individuals between 1 and 44 years and the third most common cause of death regardless of age. The abdomen is the third most commonly injured region of the body. Some intra abdominal organ injured more than others, related to mechanism of injury, size and location of organ in abdominal cavity. This study was carried out to determine the prevalence of intra abdominal injuries due to penetrating trauma. Materials and Methods: This retrospective descriptive study was done on 114 patients admitted to 5 Azar hospital in Gorgan, Iran due to penetrating abdominal trauma during 2002-07. Gender, age, type of injury causes of trauma and hospitlalization period were obtained form patients files. Results: 92.1% of patients were male. The mean age of subjects was 24.8 years (9-70 years) with highest frequency between 20-24 years. Two (1.8%) deaths directly related to abdominal stab wounds related to hemorrhagic shock. The most common cause of penetrating abdominal injury was knife wound (78.9%). The mean time spent in hospital was 4.6±2.8 days. In 53 patients, cause of trauma were either related to pentration into peritoneum or passing through in. Small intestine injuries (14 %), rupture of diaphragm and concurrent lung injuries (7%) were the common damage organs. Conclusion: This study showed that the knife was the main cause of abdominal penetrate trauma and peritoneum was the most common damage tissue.
