Abstract
Levamizole hydrochloride (C11H12 N2 S.HCl) is a drug capable of being rapidly absorbed from the gastrointestinal tract and is also rapidly eliminated from plasma. It has a modulating effect on the immunesystem, and may be used in treatment of parasitic diseases and infections. Because of its toxicity to liver and its rapid clearance from plasma, this drug must be formulated in such a way so as to decrease its necessary dosage and thus its toxic effect on the liver while improving or at least maintaining its present tolerance to disintegrating factors in the surrounding and its ability to efficiently reach its target tissues (the immune system). Therefore, the liposomal form of levamizole hydrochloride can be helpful in achieving the stated goals. In this study, first a preparation of a multilayer liposome with hydrophilic coating was done. For this purpose, a mixture of phosphate buffer (soudium and potassium phosphate I, 4 mmol, pH =7.4) ethanol and lipid (100 mg phosphatidyl choline, extracted from soya) was used (buffer 200 mg, ethanol 80 mg, lipid 100 mg). Also levamizole hydrochloride with half a solubility in water was used. The above solutions from levamizole containing liposomes under a few cycles of freeze-thawing method (20-60°C). Ultracentrifugation (45 min, 60.000 rpm) was used to determining the extent of drug encapsulation in this method we can calculate the percent encapsulation using a control. In our method this percentage was calculated to be 92.7%.

Abstract
Opioids are increasingly being recognized as the primary treatment for cancer pain management. Optimal treatment of cancer pain involves assessing its characteristics, considering different management strategies, evaluating side effects and adverse drug reactions and establishing the most appropriate therapeutic regimen. This study was designed to review the current status of pain management for advanced cancer cases using opioid analgesics.
Materials and Methods: A questionnaire was used to collect data on demographics, disease characteristics, and opioids use indicators in 700 cases of advanced cancer patients.
Results: A total of 700 cancer cases, 42 percent females and 58 percent males, between 17-80 years age range (Mean age of 57.25) were studied retrospectively. Cancers of breast (21 percent), colorectal (12 percent), lung (7 percent), stomach (7 percent) and bone either primary or metastatic (6 percent ) in women and stomach (17 percent), lung (12 percent), colorectal (11 percent), prostate (9 percent ), and bone (8 percent ) in men were the most common causes of opioids prescription in study group respectively. Advanced primary cancer (in 52 percent), bone metastasis (in 32 percent), and treatment complications (in 7 percent ) were considered as physical basis for pain in patients. Morphine (by injection), Opium (by oral intake) and methadone (injection and/or oral) were the most common opioids prescribed. Using equianalgesic conversion chart, the daily dosages and therapeutics schedules of morphine administration were as follows:
43 percent received 21-30 mg. in 2-4 divided doses
27 percent received >30 mg. in 3-5 divided doses
21 percent received 11-20 mg. in 2-3 divided doses
9 percent received 5-10 mg. in 1-2 divided doses
Conclusion: Pain management of cancer patients is not adequate and opioid use is not rational. New educational and managerial strategies are needed to optimize cancer pain treatment in routine medical practice. To overcome current barriers, WHO stepwise model for cancer pain control and palliative care is recommended. Publishing Standard Treatment Guidelines for different levels of health care system is another recommended approach to optimize cancer pain.

Abstract
Background: Pulmonary involvement is a common and serious complication of rheumatoid arthritis. This cross sectional study sought to determine the prevalence of pulmonary disease in patients with rheumatoid arthritis on the basis of history, physical examination, chest X-ray and PFT.
Materials and Methods: 103 patients (81 Women, 22 Men) fulfilling the ACR (American College of Rheumatology) criteria for RA (Rheumatoid arthritis) were consecutively included in a cross sectional study. Detailed medical (including respiratory symptoms and the disease activity symptoms) and drug and occupational histories and smoking were obtained. All patients underwent a complete pulmonary and rheumatologic examination and conventional chest radiography. All patients underwent PFT that comprised spirometry and body plethysmography.Results for PFTs were expressed as percentage of predicted values for each individual adjusted for age, sex, and height.
Results: On the basis of history: Their mean age was 43.3 ± 2.6 years (range: 17-74) and the mean duration of the disease was 69.3 ± 15.6 months. Rheumatoid factor was positive in% 61.2. No patients were 0.5Pack/Year smoker in whole life. Prevalence of pulmonary involvement based on radiographic and pulmonary function test detected in 41 patients (39/7%). The most frequent respiratory clinical finding was dyspnea (33%), (NYHA grade I in 17.5% and NYHA grade II in 15.5%), Cough (with or without sputum) in 13.6 %, Crackle was the most sign in pulmonary examination (5.8%). Chest X-ray was abnormal in 13.3 % that the most common finding in this study was reticulonodular pattern in 20 patients (19.4 %), and pleural effusion detected in 7 patients (6.7%). PFT was abnormal in 30 patients (29.1 %). A significant decrease of FEF 25%-75% below 1.64 SD. Small airway involvements was the most abnormal finding of PFT. No relation between rheumatoid arthritis disease activity (ESR>30, Morning stiffness>30', Anemia, thrombocytosis) with pulmonary disease was seen.
Conclusion: This study suggests a high prevalence of lung involvement in patients with rheumatoid arthritis.Therefore we recommend a complete investigation in patients with RA with any respiratory symptom.

Abstract
Background: Bacterial meningitis is a fatal disease with high mortality and morbidity that needs emergency management. But due to nonspecific signs and symptoms it&aposs diagnosis in children is difficult. Recently procalcitonin has been used for diagnosis of serious bacterial infections like bacterial meningitis. We conducted a prospective study in children for evaluation of procalcitonin in differential diagnosis of acute bacterial and viral meningitis.
Materials and Methods: In a prospective process research, we measured CSF procalcitonin levels in 43 children older than two months referred to Markaz Tebbi hospital. According to the results of universal PCR the patients were divided into two groups: bacterial meningitis (n=11) and nonbacterial meningitis (n=32). To analysis the results, Mann-Whitney test was used.
Results: CSF procalcitonin level in bacterial meningitis was significantly higher than viral meningitis (1.72±0.9 ng/ml and 0.71±0.04ng/ml respectively,Pvalue= 0.00). A serum procalcitonin level >0.5 ng/ml had high sensitivity and specificity ( 90.1% and 97.1% respectively) in the diagnosis of bacterial meningitis.
Conclusion: CSF procalcitonin level seems to be a valuable marker in differentiating between bacterial and viral meningitis.

Abstract
Background and Aim: With the introduction of long term subcutaneous administration of Deferoxamine there has been a decline in the morbidity and mortality of transfusion-dependent beta thalassemia patients. But parenteral iron chelation therapy is still a burden and a major reason for unsatisfactory compliance and places an additional psychological burden on the patients. There are some factors contributing to low compliance in these patients. To evaluate compliance to Deferoxamine and barriers of non adherence and assessment the prevalence of depression and it’s association with compliance.
Materials and Methods: 205 patients with major thalassemia in children medical center older than 6 years old were included. They were classified in 3 groups by compliance index (CI: No. of days of treatment per one month/No. of treatment days prescribed by physician). CI>75 % was considered good ,CI< 50-75%: moderate,CI<50%:weak and 3d group the patients without compliance. For assessment of depression: Beck Depression questionnaires were given to the patients older than 18 years old and Children Depression Inventories (CDI)“kovacs” were given to the rest
Results: Of 205 patients (110 females (54%) and 95 males (46%)), 13.3% were non compliant, 14% had poor compliance, 62.7% had good compliance. Females were more compliant than males (P=0.034). Compliance improved in older age groups meaningfully (P=0.037). There was negative association between compliance and serum ferritin level (P=0.02). 22% of children and 12% of Adults had severe depression according to the questionnaires. There was no association between compliance and depression. The most prevalent problem rgarding Desferal injection was local reactions in injection site (83%).
Conclusion: As oral chelation therapies are not used routinely, more investigations regarding the noncompliance must be considered and this method of chelation therapy must be encouraged. Compliance is a multifactorial problem, so the solution to which requires close interaction between the patient, the family and community.

Abstract
Background: This prospective phase III study was designed to compare the activity of two combinations chemotherapy drugs in advanced gastric adenocarcinoma
Methods: In a double blinded clinical trial, From Jan. 2002 to Jan. 2005, ninety patients with advanced gastric adenocarcinoma were randomly assigned to 1) Cisplatin and continuous infusion of 5FU and Epirubicin (ECF), and 2) Cisplatin and continuous infusion of 5FU with Docetaxel (TCF). Reduction in tumor mass, overall survival (OS), time to progression (TTP), and safety were measured outcome.
Results: About 90% of patients had stage III or IV disease and the most common sites of tumor spread were peritoneal surfaces, liver and Paraaortic lymph nodes in either group. The objective clinical response rate (more than 50% decreases in tumor mass) was 38% and 43% in ECF and TCF group respectively. Global quality of life increased (p=0 002) and symptoms of pain and insomnia decreased after chemotherapy. Patients in TCF had more grade one or two skin reactions, neuropathy and diarrhea. Fourteen patients underwent surgery. Complete microscopic (R0) resection had done in two of ECF and six of TCF tumors (p=0.015). Two cases in TCF group showed complete pathologic response. Median TTP was nine months and 10 months in ECF and TCF group respectively. Median OS was 12 months in both groups.
Conclusion: Although there wasn’t statistically significant difference regarded to clinical response or survival between two groups, TCF showed more complete pathologic response.

Abstract
Background: Recent studies have raised the issue of an increased incidence of polycystic ovaries (PCO) and menstrual disturbances in women with epilepsy treated with valproate (VPA). It seems that antiepileptic drugs, especially valproate, may have a functional role in altering the endocrine system of child-bearing women with epilepsy. We conducted this study to investigate the association of VPA and ovarian structural/menstrual disorders in epileptic women.
Methods: In this cross-sectional study, we compared a total of 64 epileptic patients, aged 16-45 years, 32 of whom had been taking VPA alone and 32 were on other antiepileptic drugs for a minimum duration of six months. Ovarian sonography was performed and body mass index (BMI) calculated for all subjects. We also recorded the presence of menstrual disturbances in both groups.
Results: Fifteen (46%) of the VPA subjects had PCO compared to 7 (21.9%) of the other group. In the VPA group, four (12.5%) had oligomenorrhea, one (3.1%) amenorrhea and 13 (40.6%) had irregular menstrual cycles. However, from the other group, two (6.3%) subjects had oligomenorrhea and seven (21.9%) had irregular menstrual cycles amenorrhea was not present in the non-VPA treated patients. Mean BMI was 22.5 kg/m2 among the VPA subjects and 20.1 kg/m2 in the non-VPA subjects.
Conclusions: This study supports the association of PCO and high BMI with VPA treatment. The frequency of menstrual disturbances did not differ significantly between the two groups.

Abstract
Background: Systemic scleroderma (SSc) is a generalized
connective tissue disorder of unknown origin which most notably is
characterized by skin thickening and organ damage. Endothelin-1
(ET-1) antibody plays a role in skin fibrosis. The
aim of this study was to determine the prevalence and correlation of different
manifestations of SSc with ET-1
plasma levels.
Methods: This cross-sectional analytical study was conducted on 95
patients (91 women and four men)
with scleroderma in 2006. The patients had
been referred to the Rheumatology Clinic of Shariati Hospital in Tehran, Iran.
The demographic data and signs and symptoms were entered in a questionnaire and
endothelin-1 concentrations were measured.
Results: The mean age of the patients was 38±12.29 years.
Diffuse cutaneous SSc (dcSSc)
was diagnosed in 52 and limited cutaneous
SSc (lcSSc)
in 43 patients. Raynaud's phenomenon (91%)
was the most common manifestation in the patients. The relationship between the
resorption of terminal phalanges due to fibrosis with the plasma concentration
of Endothelin-1 was statistically significant (p=0.001).
Pitting ulcers had significant relationships with endothelin-1 concentrations
too (p<0.05). No other significant relationships
were found between the other manifestation of the disease and Endothelin-1
concentration.
Conclusion: In
this study, Reynaud's phenomenon was the most frequent sign in patients with
scleroderma. Thus, it could serve as a tool for the diagnosis of scleroderma.
As there were no significant relationships between the other manifestations of
scleroderma with endothelin-1, a cohort study with a
larger sample size is suggested.

Abstract
Background : Chemotherapy-induced nausea (CIN) in the anticipatory and acute phase is the most common side effect in cancer therapy. The purpose of this study was to investigate the effect of ginger capsules on the alleviation of this problem.
Methods : This randomized, double-blind, placebo-controlled clinical trial was performed on 80 women with breast cancer between August till December 2009 in Imam Khomeini Hospital, Tehran, Iran. These patients underwent one-day chemotherapy regime and suffering from chemotherapy-induced nausea. After obtaining written consent, samples were randomly assigned into intervention and control groups. Two groups were matched based on the age and emetic effects of chemotherapy drugs used. The intervention group received ginger capsules (250 mg, orally) four times a day (1 gr/d) and the same samples from the placebo group received starch capsules (250 mg, orally) for three days before to three days after chemotherapy. To measure the effect of capsules a three-part questionnaire was used, so the samples filled every night out these tools. After collecting the information, the gathered data were analyzed by statistical tests like Fisher’s exact, Kruskal-Wallis and Chi-square using version 8 of STATA software.
Results : The mean ± SD of age in the intervention and placebo groups were 41.8 ± 8.4 and 45.1 ± 10 years, respectively. Results indicated that the severity and number of nausea in the anticipatory phase were significantly lower in the ginger group compared with placebo group (P=0.0008, P=0.0007, respectively). Also, the intensity (P=0.0001) and number (P=0.0001) of nausea in the acute phase were significantly lower in the ginger group. On the other hand, taking ginger capsules compared with placebo did not result in any major complications.
Conclusion: Consuming ginger root powder capsules (1 gr/d) from three days before chemotherapy till three days after it in combination with the standard anti-emetic regimen can help to reduce the anticipatory and acute nausea.

Abstract
Background: Ritalin has properties similar to amphetamines and is therefore used arbitrarily. The purpose of this study was to investigate the effect of ritalin on liver histology and some liver enzymes in streptozotocin-safe and diabetic rats.
Methods: This experimental study was conducted in September 2012 at Islamic Azad University, Damghan Branch, Iran. In this research, 80 male rats were divided into 8 groups of 10 rats, which included: control group consisting of healthy rats and experimental groups 1, 2 and 3 (healthy+ritalin), which ritalin was taken as daily gavage 2.5 mg/kg, as well as control group (diabetic) and experimental group 4, 5 and 6 (diabetic+ritalin) after 2 months of diabetic ritalin at doses of 2.5 and 5 mg/kg as daily gavages up to 30 days. At the end of the prescribed day, the rats were anesthetized and after sampling from the heart, samples were taken from the liver and samples were delivered to the laboratory.
Results: Significant decrease in albumin levels of experimental groups compared to control group (P<0.05) and significant increase in aspartate transaminase and alanine aminotransferase enzymes in all experimental groups compared to control group was observed. The rat liver tissue study showed that rats that had been exposed to different doses of riatalin for 30 days, had fibrosis around the arteries (2+), moderate to weak fibrosis, and infiltration of inflammatory cells around the arteries. In experimental groups (diabetic+ritalin), hepatocyte columns have no regularity compared to control.
Conclusion: Oral consumption of ritalin caused a disturbance in the balance of liver enzymes and elevated serum albumin levels in healthy and diabetic rats. In the experimental groups (healthy ritalin) and (diabetic+ritalin), the higher the dose of the drug, the increased levels of liver enzymes as compared to the diabetic group. Severe degrees of tissue alteration are observed in the group (diabetic+ritalin). The texture of the tissue in the group (diabetic+ritalin) disappeared and appeared in the texture of the disintegration.

Familial adenomatous polyposis is characterized by over 100 colorectal adenomas in the colorectum. The disease equally affects both sexes, with an incidence estimated at 1.14025-1.8300. The disease is premature in people with familial adenomatous polyposis. Patients suffering from familial adenomatous polyposis have a range of extra-intestinal diseases such as papillae, gastric, small intestine, and duodenal polyps; cutaneous wounds (lipomas, fibromas, and epidermoid cysts); desmoid tumors; osteomas; nephroderma retinal pigment epithelium, including hepatoblastoma and thyroid cancers; and pancreas, biliary system, and brain cancer. Familial adenomatous polyposis is characterized by >100 polyps in the colon that are often observed on the left side of the colon and rectum. A germline mutation in the adenomatous polyposis coli gene that can be clinically and genetically diagnosed is responsible for this disease. Several methods are available for testing the adenomatous polyposis gene. Whole-gene sequencing of all adenomatous polyposis coli exons and exon-intron boundaries with maximum sensitivity for determining adenomatous polyposis coli mutations is not affordable. Another method, the protein shortening assay, correctly identifies 80% of the mutations in families who show familial adenomatous polyposis and is less expensive than complete gene sequencing. The application of a COX-2 inhibitor for chemical prevention is limited in patients showing familial adenomatous polyposis because of cardiovascular toxicity. Aspirin does not negatively impact cardiovascular diseases and is even used as primary pharmacotherapy in patients who demonstrate cardiovascular risk factors. After 55.7 months of the diagnosis in hereditary CRC carriers, the incidence of cancer can be decreased by a dose of 600 mg/day aspirin for 25 months. After diagnosis, patients should undergo prophylactic proctocolectomy or ileoanal pouch. Undiagnosed patients having a family history of FAP must be referred to a genetic counselor and enrolled in optimal genetic and clinical surveillance programs. Recent advancements in endoscopic technology, e.g. high-resolution endoscopy, double-balloon endoscopy, and capsule endoscopy have enabled the comprehensive study of the gastrointestinal tract. Despite the limited evidence, more studies on these novel endoscopic technologies may modify the surveillance strategies for FAP patients.

Abstract
Background: Non-traumatic bone fractures are considered a pathologic condition with various etiologies, including cancer metastases, osteoporosis, and long-term corticosteroid consumption, which can affect people's quality of life. The main aim of this study was to investigate the etiology of pathological bone fractures in patients who were referred to the Hospital.
Methods: In this cross-sectional study, all patients with non-traumatic pathological fractures were included from March 2015 to February 2019 at Imam Khomeini hospital in Urmia city. Data analysis was calculated by chi-square test using SPSS.ver.17.
|
Results: A total of 168 patients participated in this study, of which 108 patients (64.3%) were female, and 60 patients (35.7%) were male with a mean age of 58.6±21.1 with a minimum and maximum age of 7 and 90 years old, respectively. According to the results, the most common etiologies consist of osteoporosis (33.3%), metastatic carcinoma (28.6%), and primary tumor (11.3%), respectively. Regarding the anatomical site involved, vertebrae (57.1%) and the neck of the proximal femur (27.4%) were detected as the most frequent sites with fractures, respectively. Moreover, a significant relationship was found between the fracture etiologies and demographics data (age and gender) (p<0.001). In this regard, osteoporosis and metastatic carcinoma were reported as the most common fracture etiologies in females and males. In addition, intertrochanteric-subtrochanteric (7.7%), distal femur (4.8%), intertrochanteric (1.2%), and acetabulum (1.2%) were considered other sites of fracture with less frequency. It is worth noting that for patients with ages less than fifty years old (<50 years old), commonly reported fracture etiology was the primary osteosarcoma, while in patients with ages more than fifty (>50 years old), osteoporosis was defined as the main fracture etiology.
Conclusion: Together, the present study results showed that osteoporosis and metastatic carcinoma were the most critical etiology of fractures, and there was a statistical correlation between demographic characteristics (such as gender and age) and pathological fracture etiologies. According to the statistical results, the most common sites exposed for fractures were also the vertebral and proximal femur.
