Abstract
Studies were undertaken to evaluate content of IgG, IgM, C3, C4, CH50 and proteines of sera from 53 drug addicts by immunological methods. Results shows an increase of IgG and no significant variatrion in the level of other Ig(S). In the same time we have seen an augmentation of gamma globuline in the protein electrophoresis pattern. The level of C3 and C4 of complement component rest unchanged.

Abstract
One hundred and sixty preterm deliveries were done at our center in (1996-97). Classification according to etiology shows that 30% of these deliveries were due to PROM, and 13.75% had to be induced secondary to underling fetal or maternal indication, in 35.6% there were maternal or fetal pathology, and in 20.6% there were no recognized reason (idiopathic). The various etiologic factors were evaluated in 160 term deliveries as control group. The preterm deliveries had significantly higher rate. There were 40 cases of perinatal mortality that included 77% of total perinatal mortality in (1996-97). Acute lack of neonatal intensive care unit in Iran requires closer attention in the future.

Abstract
Background: Several typical and atypical findings have been observed in Covid-19 high-resolution computer tomography (HRCT). To our knowledge, there is no study investigating the relationship between the presence of nodules in Covid-19 patients and the patient's condition. Therefore, the present study assessed the frequency of pulmonary nodules in Covid-19 patients according to their condition.
Methods: This cross-sectional study assessed the medical images of the patients referred to three university-affiliated centers (Nemazi, Ali Asghar and Shahid Faghihi Hospital) to perform Covid-19 HRCT from April to September 2020. The centers have been named H1, H2, and H3. Patients who were referred to these centers had good, poor, and fair conditions, respectively. The history of patients was assessed carefully. Patients' demographic information, nodule shape, number, size, location, presence of cavitation, and GGO around the nodule were assessed and recorded.

Results: Overall, 20576 patients (mean age=46.75±16.64 years old) were included in the study. Only 2.1% of cases had solid nodules. Most of them (96.76%) were accompanied by a GGO (halo sign), and only 10.42% were associated with a cavity. The good condition, patients showed significantly more solid nodules (3.46%) than others. In size of the nodules in good-condition patients (1.8 cm) is significantly larger than in fair-condition (1.22 cm) or poor condition patients (1.15 cm). 79.86%, 12.5%, and 7.64% of nodules were multiple, dual/triple, and single, respectively.
Conclusion: The frequency of nodules in the HRCTs of good-condition patients was significantly higher than in fair- or poor-conditionpatients; they also had more multiple and larger-sized nodules. The Pearson-coefficient test also revealed a small negative correlation between the presence of nodules and the patient's condition. It seems the presence of nodules indicates higher immunity to viral infections. In the follow-up, it was revealed that people who had nodules were not hospitalized in the ICU. Further study is needed to prove this point.

Abstract
Background: Osteoid osteoma is a painful benign osteoblastic lesion occurring mainly in the long bones. On the one hand, some studies have declared that post-treatment CT cannot determine the success or failure of radiofrequency ablation, on the other hand, some studies have stated that imaging follow-up can be helpful or even mandatory in some cases. The present study aims to evaluate Osteoid Osteoma's imaging features before or after radiofrequency ablation with or without curettage and during the follow-up period.
Methods: In this retrospective and cross-sectional study, we reviewed twenty seven Osteoid Osteoma patients with radiofrequency ablation who were assessed via drilling with or without curettage from March 2015 to December 2019 at Nemazi Hospital, Shiraz University of Medical Sciences.
Results: Radiofrequency ablation with drilling was used in 22(81.5%) patients, and for the rest 5(18.5%), radiofrequency ablation with curettage and drilling was performed as a treatment procedure. The overall clinical success rate was 92.6%(25/27), with a low complication rate (7.4%). The mean diameter of nidus in pre/pos treatment was 3.46±2.02 and 2.22±1.75 mm, respectively. Femur 12(44.4%) was the most common bone in the patients. Significant differences between pre/post treatment follow up examinations in nidus size (P=0.03), nidus diameter (P=0.02), bone and calcification size (P=0.005) were detected. Additionally, it depicts that the mean values of tumor size and cortical thickening decreased after treatment.
Conclusion: It is noteworthy that the present study had some limitations, including the small sample size and the relatively short follow-up period. There is no significant difference between radiofrequency ablation after drilling and curettage in treating Osteoid Osteoma. It is concluded that although there was a significant difference in pre/post-treatment imaging, there is no need for continuous imaging follow-up in treated patients without clinical complications such as pain to mitigate radiation dose risks and healthcare expenses. |
