Successful Sealing of Post-COVID-19 Bronchopleural Fistula with Computed Tomography Scan-Guided Percutaneous Cyanoacrylate Glue Injection: A Case Series.

Bronchopleural fistula (BPF), a sinus tract between the bronchial system and the pleural space, is associated with COVID-19 and can lead to pneumothorax, which increases the mortality rate. Due to the analytical status of COVID-19 patients, sealing the BPF necessitates the least minimal invasive treatment. Herein, we demonstrated a technique of sealing post-COVID-19 BPF with direct injection of cyanoacrylate glue under the guidance of a computed tomography scan. Following glue injection, the BPF was completely sealed in all four patients. In conclusion, in COVID-19 patients with small and distal BPF, percutaneous glue injection is recommended for BPF closure.

Evaluation of the prevalence of asthma and chronic obstructive pulmonary disease among opium users, and cigarette smokers and comparison with normal population in Kharameh: a cross-sectional study.

BACKGROUND: Recent studies have suggested that opium use may increase mortality from pulmonary diseases. However, there are limited comprehensive studies regarding the prevalence of Asthma and Chronic Obstructive Pulmonary Disease (COPD) among tobacco and opium users has been published. We aimed to determine the prevalence of respiratory disease among tobacco and opium users. METHODS: This cross-sectional study of tobacco and opium users and matched controls was conducted in the Kharameh Cohort, Fars, Iran. The prevalence of COPD and asthma, along with the participants demographical and spirometry data were examined. RESULTS: The average age of participants was 57 ± 8 years. Never smokers had a significant higher BMI (26.6 vs. 24.8), FEV1 (91% vs. 82%) and FVC (96% vs. 88%) values compared to participants with a positive smoking status. There was a statistical difference in the prevalence of COPD, asthma, and asthma COPD overlap (ACO) based on the participants smoking status, with the highest prevalence among opium and cigarette smokers, followed by opium users alone. Based on multivariate analysis, higher age, lower BMI, lower education than under diploma, cigarette smoking and opium use were significantly correlated with higher COPD prevalence; while lower age, cigarette smoking and opium use were significantly correlated with higher asthma prevalence. Illiterate participants had a significantly higher prevalence of COPD (23.6%), asthma (22%), and ACO (7.9%) among the educational groups. Regarding the prevalence of asthma, the higher socio-economic group had the lowest prevalence. CONCLUSIONS: Opium and tobacco users had a significantly higher prevalence of respiratory diseases, along with lower lung function tests based on spirometry evaluation.

Serum levels of erythropoietin in patients with chronic obstructive pulmonary disease and anemia.

The important association of erythropoietin (EPO) serum levels and chronic obstructive pulmonary disease (COPD) with anemia has been inadequately studied and remains a controversial issue. We aimed to shed light on this matter by comparing EPO levels in anemic and non-anemic COPD patients, along with a review of published literature. This cross-sectional study was conducted on COPD patients referred to the pulmonary clinic of Shahid Faghihi Hospital and Motahari clinic, Shiraz, Iran, for one year. We measured complete blood count, red blood cell indices, serum iron, TIBC and ferritin levels, serum EPO levels, and body mass index. Among 35 patients in this study, 28 males and 7 females were enrolled with a mean age of 54.57 ± 8.07 years. The average Forced expiratory volume in first second (FEV1) was 37.26 ± 7.33% and FEV1/FVC was 0.46 ± 0.12. Mean EPO levels were 30.29 ± 2.066 mU/mL. No statistically significant association was observed among erythropoietin levels and Hb, COPD severity, and age. There was no significant difference in EPO levels between anemic and non-anemic patients. EPO level, against the traditional expectation, didn't increase in COPD patients. EPO production also didn't compensate for the anemia of chronic disease which considers as a common comorbid disorder in these patients.

Evaluation of the appropriate use of chest CT-Scans in the diagnosis of hospitalized patients in shiraz teaching hospitals, Southern Iran.

PURPOSE: During recent years, overuse of medical imaging especially computed tomography has become a serious concern. We evaluated the suitable usage of chest computed tomography (CT)-scan, in patients hospitalized in emergency and medical wards of two teaching hospitals of Shiraz University of Medical Science. METHODS: Medical records of 216 patients admitted in two major teaching hospitals (Namazi and Shahid Faghihi), who had undergone chest radiography and at least one type of chest CT were investigated. The clinical and paraclinical manifestations were independently presented to three pulmonologists and their opinion regarding the necessity and type of CT prescription were documented. Also, the patient's history was presented to an expert chest radiologist and asked to rate the appropriateness of chest CT according to American colleague of radiologist (ACR) criteria. RESULTS: In 127 cases (59%), at least 2 out of 3 pulmonologists had the same opinion on the necessity of performing CT scan regardless of CT scan type, in 89 cases (41%) the same CT type and in 38 (17.5%) cases other CT type was supposed. Based on ACR criteria, of total prescribed CTs, 49.5% were "usually not appropriate" and 31.5% of cases were "usually appropriate". Among 109 pulmonary CT angiography, 54 (49.5%) was usually not appropriate base on ACR criteria, which was the most frequent inappropriate requested CT type. CONCLUSION: Considering the high rates of inappropriate utilization of chest CT scan in our teaching hospitals, implementation of the standard guideline at a different level and consulting with a pulmonologist, may prevent unnecessary chest CTs prescription and reduce harm to patients and the health system.

Prevalence of tobacco smoking and its socioeconomic determinants: Tobacco smoking and its determinants.

INTRODUCTION: The epidemic tobacco use is a public health concern worldwide. This study aimed to evaluate the prevalence of tobacco use and its socioeconomic determinants in the city of Shiraz, Iran. METHODS: In total, 5873 adults aged 20 and older were included in this study from the city of Shiraz, Iran, from June to October 2015. The sampling was conducted using the stratified random sampling method. Active cigarette, hookah, and second-hand smokers were labeled as tobacco users in this study. Past smokers and non-smokers were labeled as non-tobacco users. The participants' socioeconomic status (SES) was determined based on their self-reported level of education, occupation, income, and residence. RESULTS: In this study, 35.4% of the participants were tobacco users. The prevalence of active cigarette, active hookah, dual-users, and secondhand smokers was 13.3%, 8.3%, 0.4%, and 13.4%, respectively. The prevalence of tobacco use was highest among individuals with primary education level (40.9%), manual jobs (46.4%), lowest income level (38.1%), and those living in the suburban areas (36.4%). In multivariate analysis, the most socioeconomic factors related to tobacco usage were lack of academic education, manual job, and low-income level. CONCLUSIONS: Tobacco control efforts should be more focused on vulnerable groups of cigarette and hookah users in the southwest of Iran. Moreover, SES and reduction of health-related disparities and inequality should be considered a crucial concern in this regard.

The effect of atorvastatin on inflammatory markers in sulfur mustard gas induced bronchitis: a randomized double-blinded, placebo-control clinical trial.

BACKGROUND: This study was performed to evaluate the anti-inflammatory effect of atorvastatin in patients with chronic bronchitis, exposed to sulfur mustard gas. METHODS: In this randomized double-blinded clinical trial we recruited patients with chronic bronchitis after exposure to sulfur mustard gas. Ninety men 45-75 years old diagnosed with chronic bronchitis after exposure to mustard gas during the Iran-Iraq war, were randomly assigned to receive either atorvastatin (40 mg) or placebo once a day for 3 months. The interleukin 6 (IL-6), tumor necrosis factor α (TNF-α), procalcitonin, highly sensitive CRP and COPD assessment test (CAT) score was compared at baseline and after 12 weeks. RESULTS: After consuming atorvastatin for 12 weeks, IL-6 level (mean difference [95%CI]; 0.2 [- 0.05, 0.5]), TNF-α (mean difference [95%CI]; - 0.07 [- 0.2, 0.07]), high sensitive CRP (mean difference [95%CI] - 0.1 [- 1.2, 0.9]), and procalcitonin (mean difference [95%CI]; 0.003 [- 0.02, 0.03]) did not change significantly. However, in the placebo group, only IL-6 (mean difference [95%CI]; 0.6 [0.2, 1.05]) decreased significantly after 12 weeks, but levels of high sensitive CRP (mean difference [95%CI]; - 0.3 [- 1.4, 0.8]) TNF-α (mean difference [95%CI]; - 0.2 [- 0.34, - 0.06]) and procalcitonin (mean difference [95%CI]; 0.02 [- 0.001, 0.04]) did not change significantly. After 12 weeks, the mean differences in TNF- α, IL-6 level, high sensitive CRP, procalcitonin, and CAT score did not significantly differ between the two groups. CONCLUSIONS: The administration of 40 mg atorvastatin for 3 months did not significantly change the inflammatory markers or the quality of life of patients exposed to mustard gas with chronic bronchitis.

The interactions of folate with the enzyme furin: a computational study.

Entrance of coronavirus into cells happens through the spike proteins on the virus surface, for which the spike protein should be cleaved into S1 and S2 domains. This cleavage is mediated by furin, a member of the proprotein convertases family, which can specifically cleave Arg-X-X-Arg↓ sites of the substrates. Here, folate (folic acid), a water-soluble B vitamin, is introduced for the inhibition of furin activity. Therefore, molecular insight into the prevention of furin activity in the presence of folic acid derivatives is presented. To this aim, molecular docking, molecular dynamics (MD) simulations, and binding free energy calculations were performed to clarify the inhibitory mechanism of these compounds. In this regard, molecular docking studies were conducted to probe the furin binding sites of folic acid derivatives. The MD simulation results indicated that these drugs can efficiently bind to the furin active site. While the folic acid molecule tended to be positioned slightly towards the Glu271, Tyr313, Ala532, Gln488, and Asp530 amino acids of furin at short and long ranges, the folinic acid molecule interacted with Glu271, Ser311, Arg490, Gln488, and Lys499 amino acids. Consequently, binding free energy calculations illustrated that folic acid (-27.90 kcal mol-1) has better binding in comparison with folinic acid (-12.84 kcal mol-1).

A First Case of Acute Cerebellitis Associated with Coronavirus Disease (COVID-19): a Case Report and Literature Review.

Novel coronavirus (severe acute respiratory syndrome-coronavirus-2: SARS-CoV-2), which originated from Wuhan, China, has spread to the other countries in a short period of time. We report a 47-year-old male who was admitted to our hospital due to suffering from progressive vertigo and ataxia for 7 days prior to the admission. Neurological examination revealed cerebellar dysfunction, and brain magnetic resonance imaging (MRI) depicted edema of the cerebellar hemisphere associated with leptomeningeal enhancement. Cerebrospinal fluid (CSF) analysis showed mild lymphocytic pleocytosis, elevated protein, and lactate dehydrogenase. SARS-CoV-2 RNA was detected in the oropharyngeal/nasopharyngeal and CSF specimens. As a result, treatment with lopinavir/ritonavir was initiated, and patient symptoms and signs improved significantly during the course of hospitalization. To the best of our knowledge, this is the first case of acute cerebellitis associated with COVID-19 disease which is reported in the literature so far.

Smoking Water-Pipe, Opium Use and Prevalence of Heart Disease: A Cross-sectional Analysis of Baseline Data from the Pars Cohort Study, Southern Iran.

BACKGROUND: Associations between hookah and opium use and an increased risk of ischemic heart disease (IHD) have been suggested in a few studies, but more research is needed on the nature of these associations. We aimed to investigate the association between hookah and opium use and the prevalence of IHD in a population with relatively high prevalence of these exposures in Iran. METHODS: Using baseline data from the Pars Cohort Study (PCS), a prospective study of individuals aged 40-75 years in Fars province, southern Iran, we calculated adjusted and crude odds ratios (ORs) and corresponding 95% confidence intervals (CIs) for the independent association of hookah and opium use with prevalence of IHD. RESULTS: Of 9248 participants, 10.2% (95% CI: 9.5, 10.9) had self-reported IHD. Prevalence of ever use of hookah and opium was 48.9% (95% CI: 44.6, 53.6) and 10.2% (95% CI: 8.3, 12.5) among those with IHD, and 37.0% (95% CI: 35.7, 38.3) and 8.1% (95% CI: 7.5, 8.7) among those without IHD, respectively. Adjusted OR for the association with prevalence of IHD was 1.26 (95% CI: 1.08, 1.46) for hookah use and 1.71 (95% CI: 1.30, 2.24) for opium abuse. No dose-response association was found between hookah and prevalence of IHD. CONCLUSION: Hookah and opium abuse were associated with prevalent IHD in this study. Although more research is needed on these associations, particularly in prospective settings, reducing hookah and opium use could potentially reduce IHD risk.

The effectiveness of a traditional Persian medicine preparation in the treatment of chronic cough: A randomized, double-blinded, placebo-controlled clinical trial.

OBJECTIVES: The roots and rhizomes of licorice (Glycyrrhiza glabra L.) are used in traditional Persian medicine for the treatment of numerous diseases. A chronic cough is a non-specific reaction to irritation anywhere in the respiratory system. It usually lasts for more than eight weeks. The current study aimed to evaluate the effect of a modified traditional Persian medicine preparation, licorice pastille, in healing a chronic cough. METHODS: Through a randomized, double-blinded, placebo-controlled clinical trial was performed in a respiratory disease clinic in Shiraz, Iran; between October 2016 and December 2017. Seventy participants with a chronic cough took part in the trial. The outcome measures were as the daily cough scores (the score being logged via patient symptoms, diary, and the visual analogue scale) and the quality of life measure of chronic cough according to the Leicester Cough Questionnaire. RESULTS: At baseline, there were no significant differences in the demographic or clinical (cough score) characteristics between the two groups. There was complete adherence to protocol in both groups but, the drop-out rate was 4 patients in the placebo and 6 ones in the intervention groups. The results at the end of the trial (Week 2) and follow-up (Week 4) demonstrated the efficacy of the licorice pastille in terms of the cough severity score against the placebo group. This item showed a significant decrease in the intervention group (1.2 ±â€¯0.93) comparing to the placebo one (1.8 ±â€¯1.03) at follow-up time. No major side effects were reported during the study and follow-up time. CONCLUSIONS: Licorice pastille could be a promising choice in the treatment of a chronic cough of unknown origin.

Adherence to the algorithmic approach for diagnosis of pulmonary embolism: A teaching hospital experience, Shiraz, Iran.

BACKGROUND: We evaluated to see if the algorithmic approach of pulmonary embolism (PE) [Wells' score, followed by D-dimer test and computed tomography pulmonary angiography (CTPA)] is appropriately followed in teaching hospitals of Shiraz, Iran. METHODS: From October 2012 to October 2013, we prospectively calculated Wells' score for all patients who underwent CTPA with clinical suspicion to PE; patients with low probability who had not checked the D-dimer or had low level of D-dimer were considered as non-adherent to the guideline and those with high level of D-dimer or high probability of Wells' score were labeled as adherent to the PE guideline. CTPA scans were independently reported by two radiologists. RESULTS: During study period, 364 patients underwent CTPA to rule out PE, of which 125 (34.3%) had Wells' score > 4 (high probable risk) and 239 had Wells' score ≤ 4. Amongst low probable risk patients (Wells' score ≤ 4), only 32 patients had undergone the D-dimer test (23 patients had high level of D-dimer). Based on the algorithmic approach, patients with suspected PE, patients with high probability (125 patients), and patients with low probability with elevated D-dimer level (23 patients) were considered as adherent to the PE guideline; consequently, the total adherence to PE guideline was 148 out of 364 (40.6%). CONCLUSION: We followed the algorithmic approach guideline in about 40.0% of cases; however, we should pay more attention to the algorithmic approach in patients with suspected PE.

Asthma and its related socioeconomic factors: The Shiraz Adult Respiratory Disease Study 2015.

OBJECTIVE: This study aimed to explore the association between the prevalence of asthma and the socioeconomic factors using data from the Shiraz Adult Respiratory Disease Study, 2015(SARDS). METHODS: The SARDS was conducted from June to October 2015 among adult subjects of the general population of Shiraz, Iran. Current asthma was defined as the presence of at least 1 of the following factors in the preceding 12 months: (1) being awakened by an attack of shortness of breath, coughing, or chest tightness without any identifiable cause; (2) having an asthma attack; (3) currently using medication for asthma; or (4) having wheezing or whistling in the chest not associated with a cold or the flu. Information on individual socioeconomic status was derived from self-reported education level, occupation, income, and residence location. A value of P < .05 was considered statistically significant. RESULTS: A total of 4582 respondents aged 20-60 years were included in the analysis. The overall prevalence of adult asthma was 7.8%. The prevalence of asthma was higher significantly among female and subjects with higher body mass index, allergic rhinitis, smokers, jobless, and individuals who live in suburban areas. In the adjusted logistic regression model, being jobless (odds ratio [OR], 2.256; 95% confidence interval [CI], 1.123-4.535) and living in a suburban area (OR, 1.735; 95% CI, 1.058-2.845) were the most significant socioeconomic predictive factors for adult current asthma. CONCLUSIONS: It can be concluded that lower socioeconomic status is associated with higher adult current asthma prevalence. Target interventions are necessary to reduce disparities in healthcare systems.

Evaluation of Adherence to American Society of Health-System Pharmacists Guidelines: Stress Ulcer Prophylaxis in Shiraz, Iran.

Overuse of stress ulcer prophylaxis has a considerable cost burden on patient and healthcare systems. This study aimed to determine the adherence level of stress ulcer prophylaxis use with American Society of Health-System Pharmacists guidelines in a teaching hospital in Shiraz, Iran. From March to September 2013, we enrolled all eligible patients admitted to the general medical wards of Shahid Faghihi Hospital, Shiraz, Iran. According to American Society of Health-System Pharmacists guidelines, patients who had at least one major or two minor risk factors for stress ulcers and received stress ulcer prophylaxis were labeled as adherent, others were considered nonadherent. During the study period, 441 patients enrolled, of which 257 (58.3%) were women. The mean ±SD age of patients was 54.7 ± 20 years. The mean ±SD length of hospital stay for patients was 11.3 ± 6 days. Overall, 354 patients (80.2%) received proton pump inhibitors as stress ulcer prophylaxis. There were 127 patients who properly received stress ulcer prophylaxis. Total adherence to American Society of Health-System Pharmacists guidelines in our hospital was 28.8%. We observed a high frequency of unnecessary use of stress ulcer prophylaxis in hospitalized, noncritically ill patients with inappropriate continuation after discharge.

Assessing the Performance of a Medical Intensive Care Unit: A 5-year single-center Experience.

Patient care in the Intensive Care Unit (ICU) is complex and expensive, serving to provide optimal outcome as well as the adequate use of resources. Our objective was to determine variables associated with admission practices, processes of care, and clinical outcomes for critically ill patients. Admission records of a 10-bed ICU were gathered during a 5-year period. Variables such as average length of stay, bed turnover, bed occupancy rate, and turnover interval were evaluated. Of the 1719 patients evaluated, 54% were men. Mortality was highest between 10 pm and 2 am. There was no significant difference in ICU mortality during different days of the week. We showed that nonoffice hour admissions were not associated with poorer clinical outcomes, and significant differences in ICU mortality and ICU length of stay were not seen. Moreover, hospital mortality rates were not significantly higher for patients admitted to our ICU on weekends, at nights, or any day of the week.

Changing Epidemiology of Common Cancers in Southern Iran, 2007-2010: A Cross Sectional Study.

We have evaluated the ever changing epidemiology of cancers in Fars province, Iran since the re-establishment of Fars cancer registry. Based on the collected data from all related sources in Fars province from 2007-2010 we calculated the cancer age-standardized rates per 100,000 person-years (ASRs). The results are presented as incidence rates of cases by site according to the International Classification of Diseases for Oncology (ICD-O), sex, age, crude rate, and ASRs. In women the total ASR was 41.70 per 100,000 from 1985-1989 which had increased to 55.50 and 95.46 during 1998-2002 and 2007-2010. The incidence of breast cancer in women during 2007-2010 was about two and four times higher than 1998-2002 and 1985-1989. The incidence of colorectal cancer in women during 2007-2010 was about three and five times higher than 1998-2002 and 1985-1989. In men the total ASR was 62.9 per 100,000 in 1985-1989 that increased to 64.50 and 101.48 during 1998-2002 and 2007-2010. Although stomach cancer was the most common cancer among men during 1985-1989 and 1998-2002, but in recent study bladder cancer was the most common cancer among men in Fars province. The incidence of colorectal cancer in men during 2007-2010 was about three times higher than 1998-2002 and 1985-1989. This study shows growing incidence of cancer in southern Iran. The colorectal cancer in both genders had increased and its pattern is similar to western countries. In men, bladder and prostate cancers had a growing rate and the incidences of these cancers in the present study were greater than stomach cancer.

Adherence to the Global Initiative for Chronic Obstructive Lung Disease guidelines for management of COPD: a hospital-base study.

BACKGROUND AND AIMS: To determine the level of adherence to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines, we compared our inpatient management of exacerbations of chronic obstructive pulmonary disease (COPD) to these guidelines. METHOD: This cross-sectional descriptive study was conducted from January 2011 to April 2012 in a 360-bed teaching hospital in Shiraz, Iran. We recorded the management data for 96 consecutive patients with COPD exacerbation. SPSS 11.5 software (SPSS Inc., Chicago, IL, USA) was used for all statistical analyses. RESULTS: The mean (standard deviation) age of our patients was 67.3 (14) years, and more than 75% of them were men. Adherence for starting antibiotics was 84.4%. Most of our patients (82.3%) received oxygen therapy, for a level of adherence to GOLD recommendations of 74%. Nearly 95% received a short-acting bronchodilator, and 12.5% received a long-acting bronchodilator. Adherence to the guidelines was 19.8% for oral and 61.4% for inhaled steroids. Adherence to the guidelines was 49% for starting N-acetylcysteine, 77.1% for antitussives and 13.5% for xanthine derivatives (aminophylline and theophylline). The overall adherence to GOLD guidelines was 67.2% at our hospital. CONCLUSION: The level of adherence to GOLD guidelines for the management of COPD exacerbation was suboptimal at our teaching hospital. Further improvements in adherence to these guidelines are needed.

Evaluation of the Effect of Nebulized N-Acetylcysteine on Respiratory Secretions in Mechanically Ventilated Patients: Randomized Clinical Trial.

BACKGROUND: The purpose of our study was to evaluate an inexpensive and available method to reduce mucous impactions in mechanically ventilated patients. METHODS: This randomized clinical trial was conducted on 40 mechanically ventilated patients aged 15-90 years. The patients were randomly allocated into two arms; 20 cases and 20 controls. The cases received N-acetylcysteine via their nebulizers, and the control group received normal saline three times a day for one day. We measured the density of respiratory secretion, plateau and peak airway pressures, and O2 saturation at baseline, 12 and 24 hours later. RESULTS: Although the mean secretion density was significantly lower in the NAC group (F (1, 38)=8.61, P=0.006), but a repeated measures ANOVA with a Greenhouse-Geisser correction determined that the effect of NAC on mean secretion density did not differ significantly between time points (F (1, 38)=3.08, P=0.087). NAC increased O2 saturation significantly between time points (F (1.92, 73.1)=4.6, P=0.014). The plateau airway pressures were relatively stable throughout the study in the normal saline and NAC groups (F (1.95, 37.1)=0.67, P=0.513). The peak airway pressure did not change significantly during the study in the normal saline and NAC groups (F (1.52, 56.4)=0.91, P=0.384). CONCLUSION: Considering the limitations of the study, nebulized NAC in mechanically ventilated patients was not effective more than normal saline nebulization in reducing the density of mucous plugs. The peak and plateau airway pressures were relatively stable throughout the study in both groups. TRIAL REGISTRATION NUMBER: IRCT201104276312N1.

Pulmonary Embolism with Abdominal Pain and ST Elevation: A Case Report.

Pulmonary embolism is considered as a great masquerader due to its frequent nonspecific signs and symptoms. Typically pulmonary embolism is under-diagnosed or over-diagnosed. In this study a patient with pulmonary embolism is reported in which the patient exhibited two unusual manifestations namely; right upper quadrant abdominal pain and ST-T elevation in anterior precordial leads. Due to the fact that the patient did not display typical pulmonary embolism symptoms and its major risk factors, extensive workup to discern the cause was carried out. The examination included abdominal sonography, kidney ureter and bladder Computed Tomography scan (CT-scan) and coronary angiography. Eventually after a six-day delay, pulmonary embolism was diagnosed by spiral chest CT scan. This case and several other similar reports underlines the fact that while various other common causes may exist for right upper abdominal pain, one should always consider pulmonary embolism as a possible cause especially when backed up with ECG finding.

Data coverage of a cancer registry in southern Iran before and after implementation of a population-based reporting system: a 10-year trend study.

BACKGROUND: Cancer registries help to decrease the burden of cancers by collecting accurate and complete data. We aimed to measure the completeness of coverage of information recorded between 2000 and 2009 in a cancer registry program in Fars province, southern Iran. METHODS: The cancer registry program run by Shiraz University of Medical Sciences was investigated in two periods: pathology-based data from 2000 to 2007 and population-based data from 2007 to 2009. Completeness of yearly coverage was measured as the number of reported cases of cancer in each year divided by estimated cases based on 107.3 new cases per 100 000 individuals. The percentage of complete data registration (patient's name, age, gender, address, phone number and father's name) and correct cancer encoding was calculated for each year and compared to the maximum acceptable error rate for each item. RESULTS: A total of 29 277 non-duplicate cancer records were studied. Completeness of coverage varied from 22.68% in 2000 to 118.7% in 2008. Deficiencies in patients' demographic data were highest for name in 2002 (0.09%), age in 2006 (2.36%), gender in 2001 (0.06%) and father's name in 2001 (52.5%). Incomplete address (99.7%) and missing phone number (100%) were most frequent in 2000, and deficiencies in encoding information were highest in 2008 (6.36%). CONCLUSIONS: The cancer registry program in Fars province (southern Iran) was considered satisfactory in terms of completeness of coverage and information about age. However, it was deficient in recording patients' phone number and address, and father's name. The error level for cancer encoding was unacceptably high. Enhancing hardware and software resources, education and motivation in all public and private sectors involved in the cancer registry program, and greater attention to epidemiological research are needed to increase the quality of the cancer registry program, including its completeness.
