Environ Sci Pollut Res Int 2021 Apr 1. Epub 2021 Apr 1.

Department of Environmental Health Engineering, School of Public Health, Tehran University of Medical Sciences, Tehran, Iran.

This study aimed to determine the effect of land-use changes on the non-carcinogenic health risk of nitrate ion exposure of underground drinking water resources in Shiraz (Iran). To this end, 175 chemical samples for the nitrate analysis were regularly taken from 35 drinking water wells of Shiraz from 2013 to 2017, and their results were zoned using GIS. Hazard quotient (HQ) induced by nitrate ion exposure was determined in four age groups: infants, children, adolescents, and adults. Area changes of four types of land-use, including residential, agricultural and green space, industrial, and bare land within a radius of 400 m of drinking water wells, were determined using the GIS and Google Earth software. Then, all data was imported to Matlab 2018 for statistical analysis. The results showed that mean nitrate concentration increased by 2.5 mg L from 2013 to 2017. According to the zoning map, 5 and 11.4% of the area in 2013 and 2017, respectively, exceeded the drinking water standard set by nitrate (i.e., 50 mg/L). Air temperature and precipitation variations also influenced nitrate concentrations and HQ changes (R = 0.67). Children's age group was the most vulnerable, and during the study period, this vulnerability was an increasing trend, so that the HQ from 0.93 in 2013 to 0.97 in 2017 has increased. The rate of land-use changes in agricultural, industrial, bare, and urban was -1.8%, 1.3%, -4.6%, and 2.1%, respectively, and the highest correlation was observed between HQ and Diff.l residential land use (R = 0.55). According to the results, the most influential factor in HQ was air temperature (R = 0.66), and urban land-use change (R > 0.44). To sum up, this study's results showed that land-use changes, especially urban and residential development, significantly affect groundwater nitrate concentration and its degree of HQ. Moreover, increasing temperature and decreasing annual precipitation can also increase the severity of this risk.

4-chlorophenol removal by air lift packed bed bioreactor and its modeling by kinetics and numerical model (artificial neural network).

Sci Rep 2021 Jan 12;11(1):670. Epub 2021 Jan 12.

Department of Environmental Health Engineering, Shiraz University of Medical Science, Shiraz, Iran.

4-chlorophenol (4-CP) is a hazardous contaminant that is hardly removed by some technologies. This study investigated the biodegradation, and physical 4-CP removal by a mixed microbial consortium in the Airlift packed bed bioreactor (ALPBB) and modeling by an artificial neural network (ANN) for first the time. The removal efficiency of ALPBB was investigated at 4-CP(1-1000 mg/L) and hydraulic retention time (HRT)(6-96 hr) by HPLC. The results showed that removal efficiency decreased from 85 at 1 to 0.03% at 1000 mg/L, with increasing 4-CP concentration and HRT decreasing. BOD/COD increased with increasing exposure time and concentration decreasing, from 0.05 at 1000 to 0.96 at 1 mg/L. With time increasing, the correlation between COD and 4-CP removal increased (R = 0.5, HRT = 96 h). There was a positive correlation between the removal of 4-CP and SCOD by curve fitting was R = 0.93 and 0.96, respectively. Moreover, the kinetics of 4-CP removal follows the first-order and pseudo-first-order equation at 1 mg/L and other concentrations, respectively. 4-CP removal modeling has shown that the 2:3:1 and 2:4:1 were the best structures (MSE: physical = 0.126 and biological = 0.9)(Rphysical = 0.999 and Rphysical = 0.999) and (Rbiological = 0.71, and Rbiological = 0.997) for 4-CP removal. Also, the output obtained by the ANN prediction of 4-CP was correlated to the actual data (R = 0.9997 and R = 0.59). Based on the results, ALPBB with up-flow submerged aeration is a suitable option for the lower concentration of 4-CP, but it had less efficiency at high concentrations. So, physical removal of 4-CP was predominant in biological treatment. Therefore, the modification of this reactor for 4-CP removal is suggested at high concentrations.

Effect of land use on cultivable bioaerosols in the indoor air of hospital in southeast Iran and its determination of the affected radius around of hospital.

Environ Sci Pollut Res Int 2021 Mar 22;28(10):12707-12713. Epub 2020 Oct 22.

Department of Environmental Health Engineering, Shiraz University of Medical Science, Shiraz, Iran.

This study aimed to evaluate the effect of land use on hospital bioaerosols and determine the effective radius. The concentration of fungi and bacteria in indoor and outdoor air was determined by the 0800NIOSH. Then land uses were determined by Google earth within a range of 0.5-5 km around three hospitals. Data were analyzed by using Spearman correlation, and a t test was used to determine differences between groups. Data were recorded in Excel and entered into Matlab for analysis. The results of the study showed that the concentration of fungi and bacteria was higher in the indoor and outdoor hospital B (bacteria = 343-43, fungi = 106-291 CFU/m) (P = 0.04). Maximum land use was also found in hospitals A and B related to urban and bare, while in hospital C, they were urban and bare. Mathematical modeling has shown that the trend of land-use variation over different radii consisted of the Gaussian model (in hospital B) and Fourier series (in hospitals A and C). Besides, there was a positive correlation between the bare and fungal and bacterial concentrations. Finally, the most effective bare radius of application on the indoor and outdoor fungi was 4 and 5 km, respectively (R = 0.99). The effective radius for reducing fungi and bacteria by creating green space was 0.5 and 3 km from the hospital center (R = - 0.99, R = - 0.8). Based on these results, land use is an effective factor in airborne fungi and bacteria in hospitals. Therefore, their control and management of land use during 5 km is necessary to reduce pollution.

The impact of agricultural and green waste treatments on compost quality of dewatered sludge.

Environ Sci Pollut Res Int 2019 Dec 7;26(35):35757-35766. Epub 2019 Nov 7.

Department of Environmental Health, School of Public Health, Shahid Sadoughi University of Medical Sciences, Yazd, Iran.

Composting is one of the environmentally desirable methods for the management of sewage sludge. In this process, the organic matters were decomposed by microorganisms. However, different treatments can improve their qualities. This study aimed to investigate the effect of two agricultural waste wheat straw (WS) and green waste eucalyptus tree leaves (ETL) treatments on the quality of the compost produced from dewatered sewage sludge. So that, the variation trend of heavy metals, temperature, moisture, PH, and C/N ratio was considered during the composting process. The results showed that the variation of some parameters in WS and ETL such as temperature (24.68 ± 0.26 and 23.41 ± 1.35), moisture (4.5 ± 2.64 and 7.66 ± 2.51), pH (5.66 ± 0.35 and 5.97 ± 0.41), and C/N ratio (250 ± 4.08 and 60 ± 3.21) was suitable in both windrows, respectively. Likewise, trend of mineralization was suitable in both masses, because TVS (43 to 78 mg/g DW for WS and 45 to 69 mg/g DW for ETL) and TDS (21 to 55 mg/g DW for WS and 2.6 to 38 mg/g DW for ETL) decreased and increased, respectively, in the composting process. While fecal coliform (2.72 MPN/g DW) and EC (2.4mmho/cm) at WS was more than Iran's agricultural standard. As a consequence, although the quality of both masses was suitable and similar, there are some limitations for using treated compost by WS in agricultural lands due to higher levels of EC, fecal coliforms, and manganese. Therefore, quality of dewatered sludge treated compared with ETL is higher than WS. Furthermore, improvement process and application of some pretreatments are necessary for decreasing the heavy metals.

Ecotoxicol Environ Saf 2019 Apr 17;171:798-804. Epub 2019 Jan 17.

Environmental Science and Technology Research Center, Department of Environmental Health Engineering, School of Public Health, Shahid Sadoughi University of Medical Sciences, Yazd, Iran. Electronic address:

To manage the pistachio de-hulling waste (PW), investigated the co-composting process using a mixture of PW and cattle manure (CM) (5.5:10 dry weight) as well as PW and municipal dewatering sewage sludge (DSS) (1:10 dry weight) at the laboratory scale for 60 days. Compost toxicity was evaluated using the seed germination index (GI). The maximum temperatures in co-composting processes of PW+CM (51.9 °C) and PW+DSS (49.9 °C) were reported on the seventh day. The increase of temperature was higher in PW+CM and remained in the thermophilic phase for five days. In both reactors, the pH rates decreased, increased, and finally remained neutral. The C/N ratio decreased in both reactors, but the reduction rate was faster in the PW+DSS reactor. Sodium (Na%) and potassium (K%) contents were increased, while the concentrations of Cu, Zn, Fe, and Mn were decreased during the processes. The numbers of parasite eggs in the final composts of the reactors containing PW+CM and PW+DSS were zero and 8 Number/4gDW, respectively. The amounts of Salmonella were zero in the final products of reactors containing PW+CM and PW+DSS. The results of GI showed that the final compost of PW+CM process was not toxic for the plants, whereas the PW+DDS final compost was toxic. In conclusion, the co-compost product of the PW+CM reactor had higher quality than the PW+DSS reactor. So, it is suitable for PW management.

Acta Microbiol Immunol Hung 2019 Mar 11;66(1):91-101. Epub 2018 Sep 11.

4 Department of Laboratory Sciences, Golestan Hospital, Ahvaz Jundishapur University of Medical Sciences , Ahvaz, Iran.

Shigella spp. are a major cause of bacillary dysentery, particularly among children in developing countries such as Iran. This study aimed to investigate the presence of two important Shigella enterotoxins (ShET-1 and ShET-2), encoded by the set and sen genes, respectively, by polymerase chain reaction (PCR) assay among Shigella species isolated from children affected by shigellosis in Ahvaz, southwest of Iran. In this cross-sectional study, from June 2016 to April 2017, altogether 117 Shigella isolates were collected from fecal specimens of children aged <15 years with diarrhea in Ahvaz, southwest Iran. All isolates were identified by standard microbiological and molecular methods. The presence of enterotoxin genes was determined by PCR. The most prevalent isolate was Shigella flexneri (47.9%), followed by Shigella sonnei (41%) and Shigella boydii (11.1%), respectively. Shigella dysenteriae was not detected in patients' samples. The frequencies of set1A, set1B, and sen genes were 5.1% (6/117), 15.4% (18/117), and 76.9% (90/117), respectively. This study provides initial background on the prevalence and distribution of the Shigella enterotoxin genes in Shigella isolates in southwest of Iran. In addition, this study revealed a high prevalence of sen enterotoxin gene in Shigella species.

Immunohistochemical study of C-kit expression in subtypes of renal cell carcinoma.

Turk J Urol 2018 Jan 8;44(1):31-35. Epub 2018 Jan 8.

Student Research Committee, Tabriz University of Medical Sciences, Tabriz, Iran.

Objective: Renal cell carcinomas (RCCs) include about 2% of adult neoplasms and 90-95% of all renal tumors. Mostly, it is possible to distinguish RCC subtypes using hematoxylin-eosin staining. However, overlapping morphologic features cause some difficulties in making a precise diagnosis. In order to render an accurate diagnosis, additional methods such as immunohistochemical staining for c-kit have been recommended. In this study, we aimed to investigate c-kit gene expression in various subtypes of RCC.

Material And Methods: We reviewed 65 diagnosed RCC cases. Formalin- fixed, paraffin- embedded specimens were available for the cases. The expression of c-kit was evaluated using immunohistochemistry. The correlation between c-kit expression and clinicopathological parameters including patients' age and gender in addition to grade, stage, and size of the tumor were investigated.

Results: Six cases of 39 clear cell types (15.4%), 8 of 13 papillary types (61.5%), 11 of 12 chromophobe types (91.7%), and no sarcomatoid type were positive for c-kit expression. Based on chi-square test results, there was a significant relationship between RCC subtypes and c-kit expression (p=0.001). There was no significant correlation between age, sex, grade, stage, and size of the tumor and c-kit expression.

Conclusion: The expression of c-kit in RCC may have diagnostic significance in subtypes of RCC especially papillary and chromophobe subtypes of RCC.

Research Center for Health Sciences, Institute of health, Shiraz University of Medical Sciences, Shiraz, Iran.

Fungi are one of the bioaerosols in indoor air of hospitals. They have adverse effects on staff and patients. The aim of this study was to investigate the effects of three incubation temperature on the density and composition of airborne fungi in an indoor and outdoor space of hospital. Sabouraud dextrose agar was used for culture the fungi. For improvement of aseptic properties, chloramphenicol was added to this medium. The density of airborne fungi was less than 282 CFU/m. The highest density was detected in emergency room and the lowest of them was in neonatal intensive care unit (NICU) and operation room (OR). Results showed that fungi levels at 25 °C were higher than 37 and 15 °C (p = 0.006). In addition, ten different genera of fungi were identified in all departments. The predominant fungi were Fusarium spp., Penicillium spp., Paecilomyces spp., and Aspergillus niger. Moreover, the density and trend of distribution of Fusaruim spp. in the indoor space was directivity to outdoor space by ventilation system. The present study has provided that incubation temperature had effect on airborne fungi remarkably. We are suggested that more studies would be conducted on incubation temperature and other ambient factors on airborne fungi.

Idiopathic granulomatous mastitis: dilemmas in diagnosis and treatment.

Electron Physician 2017 Sep 25;9(9):5375-5379. Epub 2017 Sep 25.

M.Sc. Student of Epidemiology, Student Research Committee, Urmia University of Medical Sciences, Urmia, Iran.

Background: Idiopathic granulomatous mastitis (IGM) is a benign rare inflammatory disease of the breast. Due to its uncommon etiology, diagnosis and treatment is still unknown. Selection of a standard method for diagnosing idiopathic granulomatous mastitis is sophisticated. In view of non-definitive clinical and imaging finding, histopathology is the cornerstone of definitive diagnosis.

Objective: To determine and help solve the dilemma of treatment and diagnosis of idiopathic granulomatous mastitis.

Methods: This historical cohort study was conducted on 48 patients who referred to the general surgery clinic of Imam Khomeini Hospital of Urmia, were diagnosed with IGM and were histopathologically selected by census using the registry system, in Urmia city, Iran, during 2010-2015 so that medical reports, ultrasonography (US) and mammography (MMG) findings, follow-up information and recurrence rate were obtained from records. The data were analyzed using SPSS software version 18 and descriptive statistics were used.

Results: According to records, 68.75% of patients (n=33) had palpable mass, 45.83% of patients (n=22) had breast pain and swelling, erythema and 20.83% of patients (n=10) had purulent drainage. Of the 48 patients 12 (25%) had mammography, which revealed the following findings: mass with irregular border in 6 patients, skin thickness in 2 cases (4.16%), and parenchymal asymmetry in 4 cases (8.33%). Minimum follow-up was 24 (range 24-56) months.

Conclusions: According to our findings, histopathology of the disease is fundamental for correct diagnosis. Steroid therapy as a therapeutic method such as prednisolone was an effective and applicable choice in the treatment of idiopathic granulomatous mastitis by decreasing in inflammation.

Characterization of Oxacillinase and Metallo-β-Lactamas Genes and Molecular Typing of Clinical Isolates of Acinetobacter baumannii in Ahvaz, South-West of Iran.

Jundishapur J Microbiol 2016 May 13;9(5):e32388. Epub 2016 Feb 13.

Microbiology Department, Qazvin University of Medical Sciences, Qazvin, IR Iran.

Background: Carbapenem resistant Acinetobacter baumannii is an important nosocomial pathogen associated with a variety of infections.

Objectives: The current study aimed to characterize the antimicrobial susceptibility, analyze the prevalence of oxacillinase and metallo-β-lactamase (MBL) genes and molecular typing of clinical isolates of A. baumannii.

Materials And Methods: A total of 124 non-repetitive isolates of A. baumannii were collected from various clinical specimens in two teaching hospitals in Ahvaz, south-west of Iran. Antimicrobial susceptibility test was carried out by disk diffusion method. The minimum inhibitory concentrations (MICs) of imipenem, meropenem, colistin and tigecycline were determined using E-test. To screen for MBL production, double disk synergy (DDs) test and MBL E-test were performed. The presence of bla OXA-23-like, bla OXA-24-like, bla OXA-51-like, bla OXA-58-like, bla VIM, bla IMP and bla SPM genes was assessed by polymerase chain reaction (PCR). To identify clonal relatedness, all isolates were subjected to repetitive sequence-based PCR (rep-PCR).

Results: Based on disk diffusion results, the highest rate of resistance was observed in rifampin (96.8%). Colistin and polymyxin-B were the most effective agents in vitro. According to the MIC results, the rate of resistance to imipenem, meropenem, colistin and tigecycline were 78.2%, 73.4%, 0.8% and 0, respectively. Metallo-β-lactamase production was positive in 42.3% and 79.4% of the isolates by DDs test and E-test, respectively. All isolates (100%) carried bla OXA-51-like gene. According to the results of multiplex PCR, bla OXA-23-like and bla OXA-24-like genes were detected in 85.6% and 6.2% of carbapenem resistant isolates, respectively. No bla OXA-58- like, bla VIM, bla IMP and bla SPM were detected. By rep-PCR, carbapenem resistant isolates were separated into six genotypes (A to F). Genotype A (30.9%) was the most prevalent (P value < 0.001). Genotypes B and C were found in 28.9% and 26.8% of the isolates, respectively.

Conclusions: The rate of carbapenem resistant A. baumannii isolates were high in this study. Since, bla OXA-58-like or MBL genes were not detected, it seems that resistance to carbapenems is related to bla OXA-23-like and bla OXA-24-like. Moreover, bla OXA-23-like was the most prevalent oxacillinase (OXA) gene. Most of the isolates belonged to one of the four dominant genotypes indicating clonal dissemination in the hospitals under study. In order to control the spread of carbapenem-resistant A. baumannii, infection- control strategies are needed.

EXPRESION OF P53 IN OVARAN EPITHELIAL TUMOURS AND ITS CORRELATION WITH HISTOPATHOLOGICAL PARAMETERS.

J Ayub Med Coll Abbottabad 2016 Jan-Mar;28(1):3-6

Background: Ovarian cancers are the leading cause of death among gynaecologic neoplasms. The most common form of ovarian tumours is surface epithelial tumours divided as benign, borderline and malignant. Of particular interest are borderline tumours, because the pathologist may rely on some what vague morphologic criteria. The aim of this study was to evaluate the correlation of tumour suppressor protein P53 with macroscopic and microscopic criteria of ovarian surface epithelial tumours and distinction of borderline from malignant tumours.

Methods: We studied 109 ovarian neoplasms including 74 benign, 8 borderline and 27 malignant ovarian epithelial tumours during March 2006-March 2011 in Urmia University of Medical Sciences. Immuno-histochemical staining for P53 performed on paraffin blocks and quantified with 12- point weighted score proposed by W.Y chan.

Results: Mean P53 weighted scores in benign, borderline and malignant tumours were 0.20 ± 0.63, 0.76 ± 0.89 and 3.79 ± 4.20, respectively. There was significant difference between malignant and borderline tumours (p = 0.002) and between malignant and benign ones (p = 0.000). None of 11 immuno-reactive benign and 4 borderline tumours showed P53 expression in > 50% of tumour cells, but 11 out of 15 immuno-reactive malignant tumours (73.3%) expressed p53 in > 50% of tumour cells. P53 score significantly increases with mitotic count (p = 0.000) and solidification of the tumour (p = 0.001). There was no significant correlation with size (p = 0.277), papillary structures (p = 0.062) and grade (p = 0.578).

Conclusion: According to our results, P53 staining can be used as a helpful method in distinction of borderline from malignant ovarian epithelial tumours, especially in the manner that expression in > 50% of cells favouring malignancy.

Primary Cutaneous Leiomyosarcoma in a Young Patient Previously Misdiagnosed as Pleomorphic Fibroma.

Iran J Pathol 2015 ;10(1):69-73

Dept. of Pathology, Faculty of Medicine, Urmia University of Medical Sciences, Urmia, Iran.

Cutaneous leiomyosarcoma is a relatively rare tumor accounts for about 2-3% of superficial soft tissue sarcomas. It occurs more frequently in males in fifth and sixth decades with a predilection for extremities. We report a 27 years old male with cutaneous leiomyosarcoma of thigh, previously diagnosed as pleomorphicfibroma. The tumor composed of pleomorphic spindle shaped cells with blunt ended nuclei and high mitotic activity. Smooth muscle actin was positive. In this case, the young age of the patient and previous misdiagnosis of the tumor are interesting. Subtle histologic features of low grade leiomyosarcoma can be a pitfall in diagnosis and so affects the optimal management of the patient as it occurred in previous sample of this case.

J Pak Med Assoc 2013 Jan;63(1):111-3

Department of Pathology, Faculty of Medicine, Urmia University of Medical Sciences, Urmia, Iran.

Renal cell carcinoma (RCC) is a malignant lethal tumour with high potential of metastasis. However, metastasis from RCC to the skin is much less common. It is virtually a sign of poor prognosis. We represent a 42 years old man with bilateral RCC of clear cell type followed by metastasis to the scalp one month later. In this case the relatively young age of the patient, bilaterality of RCC and occurance of skin metastasis in the absence of recurrent kidney tumour are interesting.
