BACKGROUND: The lungs are considered the second-most frequent location for hydatid cyst in human. The current retrospective hospital-based study aimed to assess the epidemiological data, clinical presentation, and treatment outcomes of lung hydatid cyst in patients who underwent surgery for this disease in Fars province, southern Iran.
METHODS: In this retrospective study, hospital records of 224 pulmonary hydatid cyst patients were assessed in two main university-affiliated hospitals in Fars Province, southern Iran. Clinical features of patients, epidemiological data, cyst features, surgical interventions, and treatment outcomes were reviewed and analyzed.
RESULTS: A total of 224 hydatid cyst cases of the lung were reviewed. Male patients accounted for the majority of cases (60.4%). The average age of the patients was 31.13 (± 19.6), ranging from 2 to 94 years old. Of the 224 patients, 145 (75.9%) cases had only one single cyst and mostly 110 (53.9%) located in the right lung. Also, 6 (2.9%) cases had cysts in both lungs. The lower lobe of the lungs was the most common location of the hydatid cyst. The average size of lung hydatid cyst was 7.37 cm (SD = 3.86; rang: 2-24) while for the cyst areas was 42.87cm2 (SD = 52.76; range: 2-488). Regarding the surgical method, 86 (38.6%) cases were operated by lung resection surgery while 137 (61.4%) cases had lung preserving one. The chief complaints of the patients were cough (55.4%) and dyspnea (32.6%). Relapse was documented in 25 (11.16%) of cases.
CONCLUSIONS: Lung hydatid cyst is a common infection in southern Iran. Lung preserving surgery is the method of choice for the management of hydatid cyst. Relapse, which was not uncommon in our study, is a challenging feature of hydatid cyst management.

BACKGROUND Celiac disease is a common disorder but there are few studies comparing the clinical features of the disease in adults, adolescents and children. METHODS Demographic and clinical characteristics of all patients with celiac disease referred to the Celiac Clinic were evaluated and compared in different age groups. RESULTS Of 3416 participants, 473 patients were included. 302 (63.8%) were women and 171 (36.2%) were men. Overall, 325 (68.7%) and 411 (86.9%) patients had gastrointestinal (GI) and non-GI manifestations, respectively. The most common symptom in adults was psychiatric problems (66.5%), while abdominal discomfort was the most common symptom in adolescents (45.2%) and children (53.8%). According to age groups, GI manifestations were seen in 79 (66.4%), 119 (59.8%), and 127 (81.9%) children, adolescents, and adults, respectively. Adults had significantly more GI manifestations than the other groups (PR 1.167; 95% CI: 1.094- 1.244; p < 0.001). Non-GI manifestations were seen in 90 (75.6%), 174 (87.4%), and 147 (94.8%) children, adolescents, and adults, respectively. Adults had significantly more non-GI manifestations than the other groups (PR 1.112; 95% CI: 1.060-1.168; p < 0.001). CONCLUSION Our study showed that there were significant differences in the clinical features of celiac disease between the different age groups. Considering these results may help plan for future studies.

Canine visceral leishmaniasis (CVL) is endemic in the southern parts of Iran. The current study aimed at molecular and serological evaluation of zoonotic visceral leishmaniasis in dogs in Fars province, southern Iran. Blood samples were collected from 60 dogs in the three villages in Fars Province. Serum samples were tested for antibodies against L. infantum by direct agglutination test (DAT). DNA was extracted from each dog\'s buffy coat and tested by PCR, targeting the Leishmania ITS-2 region. From a total of 60 studied dogs, 25 (41.7%) were female, and 35 (58.3%) were male. Dogs\' age ranged from 1 to 7 years, with a mean age of 2.97 (±1.4) years. Anti-Leishmania antibodies were detected in sera samples of 28 (46.7%) dogs, (titre ≥ 1:320). Out of 28 seropositive cases, 13 (46.4%) were female, and 15 (53.6%) were male. Association between seropositivity and dogs\' clinical signs was statistically significant (p < .05). Leishmania DNA was detected in the buffy coat of 3 of 60 studied dogs which were all seropositive by DAT. The PCR products were sequenced and molecular analysis showed that two of the isolates were Leishmania infantum, and one was L. tropica. The high proportion of seropositive dogs indicates the important role of these animals in the epidemiology of the disease in the region. Infected dogs with or without signs, especially those that are molecularly positive, can act as an active reservoir of the disease in the area.

This Study was designed to answer the question: what are the intervention goals of women for ceasing to smoke. The present research was part of a larger study and was a pioneering systematic research conducted between September 23, 2018 and September 26, 2019 through an intervention mapping in southern Iran among professional hookah Smoking (HS) women. In order to know more about the HS among women, the behavioral and environmental correlates of HS/cessation and the determiners or fundamental causes of these factors were extracted via a systematic review and a local qualitative study. As the results revealed, the expected outcomes of the educational program concerning hookah cessation were achieved. As the realization of these outcomes requires certain changes to the behavioral and environmental dimensions, in the next step, the intervention goals of hookah cessation were identified. As the results showed, four behavioral factors involved in the unhealthy HS behavior were individual HS, Being in the Company of hookah smokers, Visiting tempting and contaminated places and Physical and mental dependence on HS (habit), In addition, four effective environmental factors were found at different interpersonal, organizational, community and policy levels. These include, respectively: recommendation and motivation for cessation by influential figures, care providers\' poor inadequate knowledge and skill, Easy acceptance of hookah in society, and the lack of effective rules. Knowledge, awareness, social norms, Motivation to comply, skill and self-efficacy, habit, were among the determining factors of hookah cessation. Employment of a systematic is based on evidence and cooperation and is guided by a assessing the needs of the target population. Such a method can suggest more purposive and relevant intervention goals so as to cease HS. The aim would be to intervene in the purposes of the above-mentioned change, as compared in predetermined interventions, and increase the chances of HS cessation among women.

Celiac disease (CD) is an immune mediated inflammatory enteropathy, triggered by gluten exposure in HLA-DQ2 and/or -DQ8 genetics. The presentation of celiac disease in children is changing, with increase in non-classical symptoms. We aim to evaluate the clinical presentations of celiac disease amongst children, diagnosed with CD.
In this cross sectional study, we investigated the clinical features of 130 celiac patients at hospitals affiliated with Shiraz University of Medical Sciences. We used their hospital charts and conducted an interview with patients and their parents to find out demographic data, symptoms, laboratory, and histopathology findings for Marsh grading.
Celiac disease was detected more amongst females (63.8%). We found that 5.4% of the patients had BMI more than 95th percentile. The most common GI symptoms were abdominal pain, flatulence and constipation. Also, the most common extra intestinal manifestation included bone pain, long term fatigue and anemia. Flatulence, chronic diarrhea, and paresthesia were observed more amongst male participants. The most common comorbidities were type 1 diabetes mellitus and hypothyroidism.
The most common gastrointestinal symptoms amongst our patients were abdominal pain, flatulence and constipation. Furthermore, the most common extra intestinal manifestations included bone pain, long term fatigue and anemia. The most associated comorbidities with CD in our children were type 1 diabetes mellitus and hypothyroidism.

BACKGROUND: Viral hepatitis is a global public health problem affecting millions of people worldwide, causing thousands of deaths due to acute and persistent infection, cirrhosis, and liver cancer. Providing updated serologic data can improve both surveillance and disease control programs. This study is aimed to determine the seroprevalence of markers for viral hepatitis (A, B, C, D and E) and the epidemiology of such infections in the general population of southern Iran\'s Hormozgan province.
METHODS: Between 2016 and 2017, a total of 562 individuals with ages ranging from 1 to 86 years, who visited governmental public laboratories for routine check-ups, were tested for the presence of serological markers to hepatitis virus types A to E using enzyme-linked immunosorbent assays.
RESULTS: The overall anti-hepatitis A virus (HAV) antibody seroprevalence was 93.2% (524/562). The prevalence of anti-hepatitis E virus (HEV) antibodies was 15.8% (89/562) among which 1.6% (9/562) of the seropositive individuals also had evidence of recent exposure to the virus (IgM positivity). Two and a half percent (14/562) were positive for hepatitis B surface (HBs) antigen, whereas 11.6% (65/562) tested positive for anti-hepatitis B core (HBc) antibodies. Among anti-HBc positive patients, 11% (7/65) had HBs Ag and 5% (3/65) were positive for anti-hepatitis D virus (HDV) antibodies. The prevalence of anti-hepatitis C virus (HCV) antibodies was 0.7% (4/562). The seroprevalence of anti-HAV, HEV IgG, anti-HBc antibodies, and HBs Ag increased with age.
CONCLUSIONS: The present study confirms a high seroprevalence of HAV infection among the examined population and reveals high levels of endemicity for HEV in the region. Planned vaccination policies against HAV should be considered in all parts of Iran. In addition, improvements on public sanitation and hygiene management of drinking water sources for the studied area are recommended.

UNASSIGNED: To epidemiologically assess the accidents and incidents in the injured pedestrians referred to Shahid Rajaee Hospital, Shiraz in order to provide basic preventive strategies and reduce injuries and fatalities caused by traffic accidents in pedestrians.
UNASSIGNED: This cross-sectional study was conducted on 5840 injured pedestrians referred to Shahid Rajaee Hospital, Shiraz from 2009 to 2014. The baseline characteristic including the demographic and clinical information, the mechanism of injury, injury severity score (ISS) and outcome determinants. We also recorded the outcome measures and the mortality. Multivariate logistic regression analysis was performed to investigate the factors related to mortality rate and Length of Stay (LOS) in hospital.
UNASSIGNED: In our study, the history of 5840 injured pedestrians was analyzed. The mean age of the patients was 41.32 ± 19.21 years. Multivariate logistic regression indicated that mortality increased with age. Moreover, the odds of mortality was more in patients with Injury Severity Score (ISS) between 16 and 24 [OR: 12.94, 95% CI (3.78-32.66), p=0.001] and injuries in the head and neck [OR: 7.92, 95% CI (4.18-14.99), p=0.020]. LOS in hospital was also higher in patients with ISS > 25 [OR: 16.65, 95%CI (10.68-25.96), p=0.001].
UNASSIGNED: Pedestrians have always been one of the most vulnerable road users. Our study indicated that the adverse consequences and mortalities in pedestrians increased with age. Hence, approaches are required to improve primary prevention programs and reduce deaths and injuries due to this major public health problem.

We obtained two blood samples from relapsing fever patients residing in Jask County, Hormozgan Province, southern Iran in 2013. Sequencing of a partial fragment of glpQ from two samples, and further characterization of one of them by analyzing flaB gene, and 16S-23S spacer (IGS) revealed the greatest sequence identity with East African borreliae, Borrelia recurrentis, and Borrelia duttonii, and Borrelia microti from Iran. Phylogenetic analyses of glpQ, flaB, and concatenated sequences (glpQ, flab, and IGS) clustered these sequences amongst East African Relapsing fever borreliae and B. microti from Iran. However, the more discriminatory IGS disclosed a unique 8-bp signature (CAGCCTAA) separating these from B. microti and indeed other relapsing fever borreliae. In southern Iran, relapsing fever cases are mostly from localities in which O. erraticus ticks, the notorious vector of B. microti, prevail. There are chances that this argasid tick serves as a host and vector of several closely related species or ecotypes including the one we identified in the present study. The distribution of this Borrelia species remains to be elucidated, but it is assumed to be endemic to lowland areas of the Hormozgan Province, as well as Sistan va Baluchistan in the southeast and South Khorasan (in Persian: Khorasan-e Jonobi) in the east of Iran.

Introduction Lupus nephritis (LN) is one of the most common complications of systemic lupus erythematous (SLE) responsible for an increase in mortality and morbidity. This study was conducted to evaluate the outcome for LN patients and factors that correlate with their outcome. Materials and methods We included 80 patients with proved LN and more than three-years follow up at Shiraz University of Medical Sciences. We prepared a data gathering sheet for each patient and extracted the data from patients\' file records which existed in the hospital. Results The mean age of patients was 36.6 ± 10.6 years, and 88.3% of patients were women. Men develop remission less than women (three men (33.3%) vs 49 women (72.1%), p = 0.014). Chronic kidney disease (GFR < 60) developed in 14.2% of our patients, and 7.8% progressed to end stage renal disease (ESRD). We found a significant relation between initial creatinine (Cr), GFR, and urine 24 hour protein with developing ESRD ( p = 0.002, 0.039, < 0.001, respectively). Also we found that hypertensive patients are at risk of developing ESRD 0.4 times more than normotensive patients ( p = 0.047, CI: 0.131-0.985). Lack of remission was significantly associated with ESRD progression ( p = 0.025). Conclusion There is a strong agreement among studies that initial Cr, hypertension and lack of remission are associated with poor outcome in LN patients. As a result we must observe hypertensive patients and patients with increased Cr more carefully. Also, we should consider changing treatment in patients who do not develop remission. In spite of dominancy of women in SLE, men are likely to have poorer outcomes.

OBJECTIVE: To update current situation of the cutaneous leishmaniasis (CL) in Kazerun County, southwest of Iran and to analyse the epidemiological aspects of the disease during 2005-2015.
METHODS: Data on CL were obtained from the Health Center of Kazerun County, and then were analysed and mapped using SPSS and Arc GIS 10.3.
RESULTS: A total of 700 cases of CL were recorded during the study period with an overall decreasing trend from 2005 to 2015. More than 60% of the patients were inhabitants of rural areas and males were infected more than females. Although there was not a significant difference between gender, job categories, residence and CL infection (P > 0.05), age groups were significantly different (P < 0.05). But there was no significant correlation between monthly cases of the disease with average temperature (P > 0.05). Most of the acute lesions were found to be present on the hand, leg and face, respectively. The average CL incidence in the study area was calculated as 24.9/100000 population. A hot spot for the disease was found in southern part of the area (P < 0.05).
CONCLUSIONS: This study revealed that CL is present in Kazerun country. Thus, effective monitoring and sustained surveillance system is crucial in counteracting the disease, and if possible, to eliminate it.
