[Non traumatic penetrating atherosclerotic ulcer of the thoracic descending aorta without associated intramural hematoma:a case report]

Penetrating atheromatous ulcer is the condition in which ulceration of an aortic atherosclerotic lesion penetrates the internal elastic lamina into the media. Differentiation of penetrating atheromatous ulcer from other causes of acute aortic syndrome such as intramural haematoma and aortic dissection is difficult. The main symptom is a severe, acute chest pain radiating to the inter-scapular area, similar to classical acute aortic dissection of the thoracic aorta. In present article a case of a 52 years old woman with long- standing retrosternal chest pain and with penetrating atherosclerotic aortic ulcer in descending aorta was reported. Unlike the predominant picture of this disease, associated intramural hematoma was not seen

Multiple mobile clots in right atrium and ventricle following insertion of temporary pace maker :a case report

Temporary pace marker [TPM] usually has been used in emergency conditions. Insertion of TPM is accompanied with vein thrombosis and pulmonary Emboli. TPM was inserted via right femoral vein in 73 years male due to complete heart block. Thereafter, he was suffered from deep vein thrombosis. Echocardiography revealed multiple mobile clots in right atrium, ventricle and impending pulmonary thromboemboli following insertion of permanent pacemaker. Despite of contraindication for the application of thrombolytic agents due to surgical incision for permanent pacemaker and presence of patent foramen oval, the patient survived from massive pulmonary thromboemboli and death due to rapid diagnosis and on time treatment with anticoagulation agents without performing surgery

[ effect of combining essences of myrtus communis and melissa officinalis in the treatment of minor aphta]

Minor aphta has a high incidence in the populations ranging from 2-50%. In spite of its frequency and severity of discomfort, there is not an absolute treatment for it. So, the main objective of this study was to evaluate the efficacy of a herbal medicine in the control of Minor aphta. In this double-blind, randomized study 137 patients with Minor aphta [with not more than four days from the onset] were selected and then placed into one of the groups of A [solution containing 5 percent Myrtus communis and Melissa officinalis in ethanol 80] and B [solution containing 10 percent Myrtus communis and Melissa officinalis in ethanol 80] or C [placebo containing ethanol 80]. Mean duration for complete recovery in minor aphta was 3.5 days in group A, 7.5 days in group B and 7.3 days in group C. There significant statistical differences the three groups [p<0.0005]. The results of this study revealed that using a combination of Myrtus Communis and Melissa Officinalis plants was effective in the treatment of recurrent aphtous stomatits [RAS]. In order to obtain the accurate concentrations of the ingredients of this compound, further studies are necessary

[Trace back of thalassemic patients with positive HCV markers to their donors in adult thalassemia center]

Transfusion transmitted infection is one of the most important transfusion reactions. In this study, we tried to find new cases of HCV in thalassemic patients having referred to Adult Thalassemia Clinic after 1996 and to trace them back for sources of infection. This was a descriptive study in which all patients were studied; census method of data collection was used. Those patients with no test record before 1996 that appeared to be positive in their first test attempt were not considered a new HCV positive case. The new cases were just those whose past negative HCV Ab test results changed into positive in new test. For data analysis, SPSS version 14 was used. Out of 395 file records, 274[69.4%] were thalassemia major, and 110 [27.8%] intermediate. We had 109 HCV positive cases [27.5%] out of whom 21 were those infected after 1996. Out of the latter, 5 had complete medical records by which 54 blood donors were identified; however, only 37 [68.5%] were traced and found to be negative for HCV Ab. Noteworthy that 81% of these safe donors were shown to be repeated donors. Since there had been one or more donors whose donations had been administered to each patient with no possibility for them to be traced, we were not able to prove the transmission of HCV from donors to recipients. Other possibilities including hospital transmission, patient to patient transmission, and transmission by nurses involved in blood administration should be taken into account

[Effects of whey protein supplementation on hematological parameters after resistance exercise in healthy young athletes]

Physical activity causes changes in hematological parameters in athletes which finally result in cessation off their exercises, an issue that should be given attention. There is limited data available about the effects of protein supplements, containing amino acids and other useful substances, on hematological parameters of resistance to exercise in athletes. This study was carried out to investigate the effect of whey protein supplementation, after resistance to exercise in healthy athletes. In this clinical trial, changes of hematological parameters were studied after one month exercise training and whey protein supplementation in 32 healthy volunteers [16 treated cases 16 control placeboes]. Each day, whey protein supplemental 6.6 g/day] and placebo [same dose, starch] were consumed between meals, by the volunteers. Every one exercised with 80% 1RM, basically on stationary circuit principal, for one hour a day, five days a week. Before and after beginning of study, fasting blood specimens were taken and WBC, RBC, HGB, HCT, MCV, MCH, MCHC, PLT and percent of white blood cells were measured separately. Statistical analyses were carried out using Student t- test and paired t-test [SPSS version 15]. Levels of WBC, RBC, HGB, HCT, PLT, MCHC in two groups significantly [P<0.05] decreased, but there was no difference between two groups. MCV increased in the groups, but again there was no difference between them. MCH and percent of lymphocytes were unchanged in both groups. In the supplement group, the percentages of the neutrophils and other white blood cells showed no significant changes, but in the placebo group, there were significantly increased and decreased, respectively. However there was no significant difference between the two groups in the percentage of white blood cells, separately. The present study showed that one month of Whey protein supplementation with 6.6 g/day is ineffective on hematological parameters changes after resistance to exercise. Further studies, with different dosages and longer periods of time are recommended
