Abstract
Cardiopulmonary resuscitation (CPR) is one of the most important skills that every body must know it in medical services. In educational hospitals, the (Newly-arrived residents are in first cell for management of victims, specially in emergency rooms and at nights. Their knowledge and ability for successful CPR have a direct relation with prevalence of total mortality and morbidity. This research has assessed the knowledge and attitude of the new residents about CPR, and for answering to this question: "Is the CPR workshops necessary for all of the new residents in the beginning of their courses". All of the 506 new residents were examined simultaneously in 2 separate years with a questionnaire consist of 50 questions about their CPR secence and skills and 8 questions about their attitude in CPR. These informations were analyzed by SPSS and EPI6 softwares. The mean correct answers were 55%±11.8. The best results were about arrythmias (68.6%) and airway management (63.6%) and the worst were about IV access (43.1%) and pediatric CPR (31.5%). These findings were similar in 2 sequential years. Their knowledge had significant relation with sex (P=0.002), their original university (P=0.031), their residency course (P=0.024) and their residency reception scores (P<0.001). Males and knowledge more than females. The max scores were from Kerman (62%) and Beheshti universities (60.5%) and the min score were from Hamadan (48%) and Kashan universities (37%). The orthopedic (62.5%) and urologic residents (61.6%) had the most knowledge and the gynecology residents (53.8%) had the least. The knowledge had no relation with the time of graduation. About their attitude in CPR: Their knowledge was moderate (65.8%), their abilities was moderate (58%) and their education about CPR in MD course had been low (51.5%). Their references for education had been individual studies (74.6%), CPR workshop had not been condected in the most universities (92.7%). knowledge about CPR is low (55.8%) and must be 100%. In advanced centers, continuous educations in CPR is essential. Residents with low scores have accepted in courses that have more CPR situations. Difference in knowledge of residents from different universities, show the different educations. Primary knowledge was low and after years, this is lower. Attitude of residents show the low knowledge, low ability, low education in MD, courses.

Abstract
Background: Premature coronary artery disease (CAD) has a familial predisposition and
occurrence. We determined the prevalence of CAD and related risk factors in individuals
with a history of premature CAD in their first-degree relatives.
Methods: This study included 700 healthy individuals with a history of premature CAD
in their parents or siblings in Tehran Heart Center in 2003-2004. History of smoking,
diabetes mellitus (DM) or hypertension was taken. Fasting levels of blood sugar (FBS),
triglycerides (TG), cholesterol, LDL and HDL were measured. Noninvasive studies for
CAD were performed with resting echocardiography (ECG) and ECG with exercise
tolerance test (ETT). Patients with positive findings for ischemia in these tests underwent
a myocardial perfusion scan and if positive proceeded to coronary angiography.
Results: The mean age of our subjects was 35.2 (15-65) years. DM was found in 5.3%,
smoking in 14.7%, hypertension in 20.6%, cholesterol above 200 mg/dl in 39.9%, TG
above 150 mg/dl in 58.6%, LDL above 130 mg/dl in 38% and HDL below 40 mg/dl in
32.6%. In addition, 6.4% had ECG changes and 3% echocardiographic abnormalities in
favor of ischemia. ETT was positive in 7.3% and myocardial perfusion scan in 2.1%.
Coronary angiography showed 50-70% stenosis in eight patients (1.1%) and >70% in
four patients (0.6%).
Conclusion: High cholesterol, TG and LDL and low HDL were found among our
subjects. Risk factor determination in these individuals may prove to be beneficial.
Noninvasive tests for CAD yield low true-positive results and are not recommended in
the population as a whole. In certain subgroups, including those with persons older than
40 years and diabetic patients, these tests may be useful.

Abstract
Background: Several randomized controlled trials have demonstrated the safety and efficacy of drug eluting stents (DES) in selected groups of patients with less complicated diabetes. We conducted this study to determine how an unselected group of diabetic patients in Iran fare following DES implantation.
Methods: Data were collected on 147 consecutive diabetic patients who underwent percutaneous coronary intervention (PCI) with the implantation of at least one DES at the Tehran Heart Center from June 2003 to September 2005. Clinical follow-up was performed by timely scheduled visits at one, four and nine months following DES implantation. Nine months of follow-up was completed for 94.5% of the patients. The primary endpoint was the occurrence of major adverse cardiac events (MACE), which include cardiac death, myocardial infarction and target vessel revascularization (TVR). In-hospital complications were the secondary endpoint.
Results: A total of 158 coronary artery lesions were treated with DES in 147 diabetic patients (mean age = 56.4±8.92 years, 57.1% were men). During the nine-month follow-up, MACE occurred in 3.4% of patients, with a myocardial infarction rate of 1.4% and TVR rate of 1.4%. Considering one patient who underwent TVR due to acute stent thrombosis following angioplasty (during hospitalization) the total number of TVR reached 3 (2%). Only one patient (0.7%) died of cardiac death, which occurred after the procedure and before discharge. In-hospital complications occurred in six patients (4.1%) five patients suffered from myocardial infarction.
Conclusions: PCI with DES seems to be safe and effective in diabetic patients. However, more studies with larger study populations and longer follow-up are required to confirm this issue.

Abstract
Background: Hypomagnesemia is commonly encountered in patients with a wide variety of diseases including subarachnoid hemorrhage (SAH), cardiovascular emergencies, head trauma, migraine attacks, seizure and preeclampsia. It seems to be associated with a poor clinical outcome. This study considers the prevalence and temporal distribution of hypomagnesemia after aneurysmal SAH and its correlation with the severity of SAH, delayed cerebral ischemia (DCI) as well as the neurological outcome after a period of three months.
Methods: Between 2003 and 2008, 60 patients were admitted to the emergency ward of Imam Khomeini Hospital with acute SAH. Serum magnesium levels were measured during the first 72 hours, days 4-7, and second and third weeks after SAH. The three-month outcome was assessed according to the Glasgow Outcome Scale (GOS). Clinical SAH grading was performed according to the criteria of the World Federation of Neurological Surgeons (WFNS) and the patients were allocated to "Good" (GOS = 4, 5) and "Poor" (GOS= 1-3) outcome groups. The prevalence of hypomagnesemia was assessed in both patient groups. Fisher exact test was used to analyze data.
Results: Hypomagnesemia occurred in 22% of patients during the first 72 hours after SAH. It was associated with more prevalent DCI (p<0.05), whereas low serum magnesium levels during days 4-7 17% of patients) and the second week (22% of patients) after SAH were correlated with poor clinical outcome (p<0.05). No correlation was found between first 72 hour-hypomagnesemia and poor clinical outcome at three months.
Conclusion: Hypomagnesemia occurs after aneurysmal SAH and it may predict the occurrence of DCI, while low serum magnesium levels during days 4-7 and within the second week of event predict poor clinical outcome at three months. Treatment of this electrolyte disturbance may have a favourable effect on the clinical outcome of patients with aneurysmal SAH.

Abstract
Background: Since the systemic steroids are introduced in Pemphigus Vulgaris treatment, the prognosis of disease improved significantly. This study was designed to evaluate determining factors in the prognosis of pemphigus vulgaris in Iranian patients.
Methods: In this study, 119 patients with documented pemphigus vulgaris who had presented to Razi Hospital from 2001 until 2003 were included. These patients had presented for the first time and treated with prednisolone and Azathioprine. Morality rate, minor and major relapses and duration of first remission had been defined as prognostic criteria and correlation between them and other demographic variables and disease characteristics were investigated.
Results: The majority of patients (84.1%) were followed for more than one year. The major recurrence and minor recurrence occurred in 28(23.5%) and 65(54.6%) of patients respectively, no case of mortality was observed. In patients who received treatment six months or less after onset of disease the frequency of major recurrence was less than the others. 18(17.8%) vs. 12(41.4%), (p=0.009). Duration of primary remission more than one year was detected in most of the patients (64.7%). In patients with less than 10 initial cutaneous lesions, period of primary remission was longer than the other patients. (p=0.009). Shorter duration of primary remission were noted in older patients (age>50) in comparison with younger patients (age≤50, p=0.04).
Conclusions: Male gender, old age, interval more than 6 months between onsets of symptoms to initial treatment and more than 10 skin lesions on admission, are associated with poor prognosis of pemphigus vulgaris.

Abstract
Background: Scorpion envenomation is considered as one of the Public Health problems in some countries in the world including Iran. Annually, approximately 30,000 scorpion stings happen in Iran from which 12% belongs to Hemiscorpius lepturus (special small closely spaced, bead-shaped jointed tail, similar in the shape to a cows tail, and is locally called ‘‘gaodim'' (Gao, cow dim, tail)) with 95% mortality. The main treatment is antiserum therapy which is produced in horse and is the only way to neutralize the venom. Due to the anaphylactic shock of the horse antiserum in some of the stung patients other source of antiserum is recommended. In this study the ability of produced camel antiserum in neutralizing the scorpion venom of Hemiscorpius lepturus was performed in Balb/c model.
Methods: Camel is an animal model that genetically is compatible with human genome utilized in this research to produce antiserum against scorpion venom. Two camels were used for immunization with the venom of Hemiscorpius lepturus. ELISA method was used to confirm the immunity. Antiserum was produced and used for neutralizing test. The precipitated antiserum with saturated ammonium sulfate (SAS) was also used to perform the neutralizing test in mice.
Results: The results indicated that the amount of 200 µl of antiserum and 400 µl of SAS antiserum were able to neutralize the amount of 1 LD100 of the venom and the survived the mice from death.
Conclusion: The result indicated that camel antiserum against scorpion venom is capable to neutralize the crude venom in mice model. Due to the safety of camel serum in human, it is suggested that the produced antiserum in camel can be substitute with the traditional horse antiserum in scorpion stung patients.

Background: Breast
cancer is the most common form of hereditary cancer worldwide and is an
important cause of morbidity and mortality. Approximately 5-10% of breast
and ovarian cancers are
due to the highly penetrating germline mutations in cancer predisposing genes. Two genes, BRCA1 and BRCA2, account for
at least half of these cases. The demand for BRCA1 and BRCA2 mutation screening is rapidly
increasing as their identification will affect the medical management of people
at increased risk for the disease. Therefore, the aim of this study was to
investigate BRCA1/2 mutations in 100 high risk Iranian families.
Methods: One hundred families who met the
minimal risk factors for breast/ovarian cancer were screened among
the families referred to Kawsar Human Genetics Research
Center for the diseases in 2009-2011. The entire coding sequences and each
intron/exon boundaries of BRCA1/2 genes were screened for by direct
sequencing and MLPA in both patients and the controls.
Results: In the present study, we could detect
the following novel mutations:
p.Gly1140Ser, p.Ile26Val,
p.Leu1418X, p.Glu23Gln,
p.Leu3X, p.Asn1403His,
p.Asn1403Asp, p.Lys581X,
p.Pro938Arg, p.Thr77Arg,
p.Leu6Val, p.Arg7Cys,
p.Leu15Ile, p.Ser177Thr,
IVS7+83(-TT), IVS8 -70(-CATT),
IVS2+9(G>C), IVS1-20(G>A),
IVS1-8(A>G), p.Met1Ile,
IVS2+24(A>G), IVS5-8 (A>G),
IVS2(35-39)TTcctatGAT,
IVS13+9 G>C in BRCA1
and p.Glu1391Gly, p. Val1852Ile,
IVS6-70(T>G), 1994-1995
(InsA) in BRCA2.
Conclusion: Ten mutations seemed to be pathogenic and the disease-causing
mutations were seen in 16% of the families. In addition, from the
total number of substitutions and reassortments (42), 80% related to BRCA1 and 20% to mutations in BRCA2 genes.

Abstract
Background: Neonatal seizures can have many causes. Determining the underlying cause of neonatal seizures is very important in determining the prognosis, outcome, and treatment strategies. In this study, we have evaluated the frequency of Magnetic resonance imaging (MRI) findings in neonates younger than 6 months who had been referred to Shiraz Namazi hospital with seizures to determine the prevalence of various causes of seizures.
Methods: This was a retrospective study, that was performed on 199 neonates younger than 6 months of age who were hospitalized due to seizures in hospitals affiliated with Shiraz medical sciences from 21st March 2018 to 20 March 2019. Patient data were extracted by statistics and health information system and imaging data and its reports were extracted from picture archiving and communication system. The data were statistically analyzed by SPSS V26.
Results: In this study, 199 infants under the age of 6 months were examined, of which 124 (62.3%) were boys and 75 (37.7%) were girls. 97 infants (48.7%) were less than one month old and 102 ones (81.3%) were in the age group of 1-6 months. It should be noted that in terms of gender, 57.3% (71) of male infants and 49.3% (37) of female infants had abnormal MRI findings. 54.3% of patients had abnormal MRI findings and 45.7% had normal MRI. The most common abnormal finding was hypoxic-ischemic encephalopathy (HIE), which was the most common cause of seizures in 21.1% of neonates, followed by infection with 12.5% and cerebral hemorrhage with 11% of prevalence. Other important abnormal findings included hydrocephalus, structural abnormalities, venous sinus thrombosis, brain atrophy, developmental abnormality, etc. There was a combination of radiological findings in 18.56% of neonates.
|
Conclusion: This study showed that hypoxic-ischemic encephalopathy is the most common cause of neonatal seizures. Considering that in this study, a significant percentage (54.3%) of the neonates had abnormal brain MRI, this finding indicates the importance of performing this radiological procedure in the diagnosis, prognosis, and duration of treatment in neonatal seizures.

Abstract
Background: CT is the gold standard method for diagnosing kidney and urinary tract stones. This imaging technique delivers radiation dose to patients, which increases the risk of cancer, especially in patients who need frequent assessment. The aim of this study was to compare the diagnostic ability of ultrasound in Iran compared to CT for diagnosing kidney stones in patients with colic pain.
Methods: The data of this cross-sectional retrospective study was gathered from the patients who were admitted to a University-affiliated hospital, Shiraz University of Medical Sciences from March 2019 to September 2019 suspected of nephrolithiasis and performed CT were collected along with their ultrasound reports. To compare sonography and CT, sensitivity, specificity, and positive and negative predictive values were calculated and the diagnostic percentage difference between the two modalities was evaluated. The diagnostic efficiency of ultrasound in stones of different sizes and locations was also evaluated.
Results: The sensitivity, specificity, and positive and negative predictive values of ultrasound in the initial diagnosis of stones were 83.47%, 62.15%, 85.94% and 57.58%, respectively. Ultrasound diagnosis was not significantly different from CT p=23 actually ultrasound diagnoses were different from CT in only 2.11% of cases. Ultrasound was the most successful in detecting bladder and urethra stones larger than 10 mm.
|
Conclusion: The results of this study showed that although ultrasound is less sensitive than CT in the diagnosis of nephrolithiasis, the use of ultrasound could be useful as a primary diagnostic test in patients with suspected nephrolithiasis. The important point is that the strategy of starting the evaluation with ultrasound, and performing additional imaging if necessary, leads to a reduction in the radiation dose of patients with nephrolithiasis. These patients have to do this procedure many times to diagnose and follow up the disease and clearly the offered method leads to reduction of the radiation absorbed dose and the possible effects of radiation, which is in line with the principle of ALARA, the basic principle of radiation protection.

Abstract
Background: The image quality is paramount in interpreting the hepatic dynamic CT scan. A poor quality image results in repeating the procedure, which is very time-consuming for the patient and staff, and besides, it is not cost-efficient. This study intended to determine the correlation between image quality and the Hounsfield unit (HU) of the liver and its vessels in the arterial and venous phase to define the acceptable range of HUs for hepatic CT images.
Methods: The image quality of 146 dynamic CT scans was assessed by qualitative and quantitative methods at Namazi Hospital of Shiraz University of Medical Sciences from September 2019 to August 2021. Two radiologists performed the qualitative evaluation. They categorized the image qualities into three groups; poor, acceptable, and high quality. For quantitative assessment of image quality, the Hounsfield unit of the aorta, hepatic vein, main portal vein, right anterior, right posterior, and left lateral lobe of the liver were evaluated in both arterial and venous phases.
|
Results: According to the results of the qualitative evaluation of image quality, 59.6%, 17.8%, and 22.6% of triphasic CT scans had good, acceptable, and poor quality, respectively. There was a significant relationship between image quality and Hounsfield units of all ROIs in the arterial phase (P<0.005). Also, a significant relationship was observed between the Hounsfield units of the portal vein right on the anterior and posterior segments of the liver (P<0.03) in the venous phase.
Conclusion: In a high quality triphasic CT scan, the Hounsfield unit of different parts in the arterial phase should be as follows: aorta 310±78, portal vein 150±40, hepatic vein 44±7, right posterior and anterior and left lateral segments of liver 77±11, 77±7 and 78±12. Hounsfield units of the portal vein, hepatic vein, and right posterior and anterior segments of the liver in the venous phase should be 155±27, 167±30, 111±19, and 112±16, respectively.

Abstract
Background: Fine needle aspiration biopsy (FNAB) is usually used to distinguish the malignant and benign nodules. Applying a biopsy needle evokes a sense of fear and pain in the patients. Although some studies refute the usefulness of local anesthesia (LA) prior to fine needle aspiration biopsy, it is still debatable. This prospective cross-sectional study intended to evaluate the effect of LA prior to fine needle aspiration biopsy on pain and anxiety considering nodule size.
Methods: Amongst the patients who were referred to Shiraz Shahid Fagihi Hospital for Thyroid fine needle aspiration biopsy from August 2017 to January 2018, 114 patients participated in this study. LA was performed for 41 patients, and 73 underwent the thyroid nodule fine needle aspiration biopsy without LA. Patients' pain and anxiety were scored using the visual-analog-score and Spielberger anxiety scale. The nodules were categorized into five groups. Pain and anxiety of patients were compared considering their nodule sizes to assess the effects of LA in the reduction of pain and anxiety considering the nodule size.
|
Results: The patients undergoing LA had a mean age of 44.69 years old and average body mass index (BMI) of 26.7, the patients who performed thyroid nodule fine needle aspiration biopsy without LA had a mean age of 48.17 years old with an average BMI of 26.0. The patients with the maximum nodule size of<10 mm, experienced more pain during the fine needle aspiration biopsy without LA, but there was no significant difference between the S/T-anxiety of these patients. There was no significant difference between the pain and anxiety scores of the patients with larger nodules.
Conclusion: The more pain experienced by the patients with the smallest nodules can be attributed to the need for more needle manipulation due to the small nodule size and less precision while piercing the needle into the nodule. Thus, it can be suggested that in patients with a small nodule size, less than 10mm, usage of LA prior to fine needle aspiration biopsy can reduce the pain significantly.

Abstract
Background: Chronic low back pain (CLBP) is one of the most common spine disorders, which is seen in 65-80% of people. Knowing the normal patterns of spine and pelvic parameters is very helpful in determining the susceptible subjects for CLBP.
Methods: This study was conducted in healthy people during April 2017 until April 2018 in Golestan hospital of Ahvaz. Inclusion criteria include; Age group 20-65 years, no history of surgery, spine disorders, and having normal radiographs were performed. People who have complained of back pain in the last three months, neuromuscular disease, lumbosacral anomalies, kyphosis and obvious scoliosis, history of spine surgery and vertebral fracture, were excluded. A 36-inch radiology stereotype was prepared in the standing position. Pelvic and spine parameters that were investigated in this research included the following, Pelvic incidence, Pelvic tilt, Sagittal Vertical Axis, T9 Sagittal Angle, Thoracic Kyphosis, Lumbar Lordosis, and Sacral Slope. All data were analyzed with SPSS software, version 24 (SPSS Inc., Chicago, IL, USA).
|
Results: 50 participants including 27(54%) men and 23(46%) women with an average age of 33±12.5 years and BMI of 25±5.5 kg/m2 were examined. After examining the vertebral and pelvic parameters, it was found that PI is significantly higher in women than in men (P=0.02). It was also found that with increasing age, the amount of Pelvic incidence also increases (P=0.043), so that in people over 60 years of age, the amount of pelvic incidence is significantly higher than other people (P<0.05). Further analyzes showed that BMI has a direct effect on the amount of Thoracic Kyphosis (P=0.03) and Lumbar Lordosis (P=0.04). Thus, the highest amount of Lumbar Lordosis and Thoracic Kyphosis was seen in people with BMI 30-34.9 Kg/m2.
Conclusion: The findings of the present study showed that spine and pelvis indices have an important effect on the occurrence of CLBP. Hence, it is highly recommended to check these parameters in asymptomatic people, especially in older people.

Abstract
Background: Prostate enlargement is a common issue amongst men, which causes significant side effects for aging men. Regarding the high prevalence of prostate enlargement and opium addiction and its derivatives, assessing the relationship between opium use with prostate enlargement may be an exciting issue.
Methods: This was a cross-sectional study. There were two groups; the case group contained men with a history of at least one year of opium abuse. The control group was men in the same age range referred to university-affiliated hospitals for ultrasonography for other reasons except for prostate problems. The prostate size and demographic information of patients were recorded. The prostate volume of more than 20 ml was considered as an enlarged prostate.
|
Results: 212 males participated in the study from December 2018 to March 2019 at Namazi Hospital of Shiraz University of Medical Sciences, including 78 drug abuse patients (mean age=39.08±6.52 years old) in the case group and 134 (mean age=40.69±6.28 years old) in the control group. The mean prostate size in the addict group was significantly higher than in the healthy group (P=0.005). There was a significant correlation between the size of the prostate and the age in both groups. However, there was no correlation between prostate size and body mass index.
Conclusion: Due to a decrease in the sexual desire of addicted people, we first expected to face smaller prostates in addicted men; however, the study results proved the opposite. One explanation can be that the decreased libido increases the likelihood of fluid accumulation in the prostate, this might lead to chronic inflammatory reactions, hypertrophy, and prostate hyperplasia. Therefore, a more comprehensive study is needed to investigate the interaction between the drug and prostate tissue. Finally, it can be concluded that addiction to opium and its derivatives can increase the chance of prostate enlargement. Due to the lack of previous studies in this field, it seems necessary to conduct additional studies with larger sample sizes and control confounding factors.

Abstract
Background: Traumatic Spinal Cord Injury (TSCI) is one of the catastrophic events, the rate of which has been growing compared to the past decades. Complications caused by TSCI have a wide spectrum and can range from complete paralysis to numbness of the limbs. Additional to the injury severity and disability of the patient, the recovery rate depends on the treatment strategies. Despite extensive efforts and research in this field, there are still few treatment options for TSCI patients. Controversial results have been reported, however, spinal cord decompression is the only certainty for the treatment of these patients. In the present study, patients with thoracic and lumbar fractures were undergone decompression, less and more than 24 hours, and the recovery rate (RR) was compared after 6 months.
Methods: In this study, patients with lumbar and thoracic fractures who were referred to the neurosurgery department of Ahvaz Golestan Hospital during May 2019 to December 2021 were included. Decompression was performed at the fracture level as a total and at the upper and lower levels of the fracture as a partial decompression. To evaluate fine motor movements, picking up a small object with toes and following a rectangular path were used. Also, the gross motor movements, upper and lower proximal and distal muscle forces were measured.
| Results: 160 patients including 133 men (83.1%) and 16.9% women (27) with 36±12 years mean age were included. The most fracture location was lumbar (53.1%), followed by the thoracic (43.1%) and fractures in both regions (3.8%). The most injured vertebras were L1 (27.5%) and T12 (18.8%). Six months later, 61.9% of patients had a good score for removing a small object with toe, of which 67.5% belonged to patients with<24 hours surgery (P=0.01). Also, RR for ability to follow a rectangle (P=0.017) and lower limit gross motor were significantly better in patients with<24 surgery (P=0.02). However, no significant difference was found between the two groups for improved sensations (P<0.05). |
Conclusion: This study showed that decompression<24 hours in TSCI is associated with a significant improvement in lower fine movements.

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. |
