Alireza Rajaei, Pooneh Dehghan, Zahra Farahani
Open Journal of Pathology (OJPathology) , 2015, DOI: 10.4236/ojpathology.2015.52010
Abstract: Background: Microcirculation is affected in diabetes mellitus and Microvascular abnormalities cause persistent diabetic complications. The aim of this study was nailfold capillaroscopic assessment to describe the pathological changes (morphological and structural) in capillary of a large series of patients with type 1 and 2 diabetes. Methods: A cross-sectional study was carried out in a Nailfold Capillaroscopy Center (Tehran-Iran) between 2011 and 2014. The study included 235 types 1, 2 diabetic patients. All patients underwent 10 nailfolds capillaroscopy examinations. Microvascular architecture, disturbances capillary distribution, capillary morphology, capillary density, efferent/afferent limb ratio, subpapillary venular plexus, and morphological abnormalities were evaluated. Conclusions were stated as normalor scleroderma pattern. Results of patients’ capillaroscopic images were recorded and analyzed quantitatively and qualitatively. P value < 0.05 was considered as statistical significance. Results: of all participants with mean age 59.91 ± 12.39, 183 cases (77.9%) were female and 52 (22.1%) were male. Tortuosity of capillaries was more often observed in our subjects (235 cases) followed by angiogenesis (171 cases). Normal and early scleroderma patterns were observed in 195 (83.0%) and 40 cases (17.0%). Based on P values, altered micro vascular architecture, capillary distribution and capillary morphology were more frequent in patients with scleroderma pattern in comparison to patients with normal pattern (P value < 0.05). Morphological abnormalities except from neo formation capillary and mega capillary were also significantly more common in patients with scleroderma pattern than patients in counterpart group (P value < 0.05). Conclusion: Nailfold capillaroscopy as a non-invasive, diagnostic and prognostic method may potentially affect on diabetes outcome and control.

Abstract: Premature infant is an infant who was born before the end of 37th weeks of pregnancy. Approximately 9.6% of infants are premature and they can be at risk for hospitalization. This study has done for evaluation of awareness and knowledge of parents about problems of premature infants in Neonatal Intensive Care Unit (NICU). This was a descriptive study with 160 parents whose premature infants were admitted to NICU (Tehran-Iran, 2009-2011). Data were collected by a questionnaire for evaluation of awareness and knowledge of parents about problems of prematurity, and then analyzed by using descriptive analytic statistical methods and SPSS software. Based on the results, there was a significant relation between age and the total score of questionnaire (P = 0.022, R = 0.18). Mothers had higher awareness and knowledge than fathers (P < 0.05). The most awareness in parents was about doing of hygienic principle when they entered to NICU and about the importance of regularly and continuous attendance in ward. Awareness and knowledge of parents about problems of their premature infant were related to their age and being a mother or father. Parents had little knowledge about some NICU principles and premature infant’s needs and care.

Open Journal of Obstetrics and Gynecology (OJOG) , 2015, DOI: 10.4236/ojog.2015.55038
Abstract:

Background: Risk management is improving quality of health care services and creating a safer system of care. We determined the main maternal and fetal risks in five Hospitals (Tehran-Iran) to offer some practical strategies to decline obstetric adverse events and provide better pregnancy outcome. Methods: A descriptive, cross-sectional study was carried out in 5 Iranian hospitals (2011-2012).Twelve Obstetricians/perinatalogists and midwives from 5 hospitalswho were in charge of Maternity Units, were our assistants in these hospitals. We organized a secretariat including Obstetricians/perinatalogists and midwives. The principles of Obstetrics Risk Management were introduced to them in a 2 days’ workshop. Then the delegates from each hospital were asked to report the most common obstetrical complications of their hospitals. The main results were 24 complications. Then for sorting these risks we asked them to do scoring of the 24 complication with 1 - 10 grading in 4 aspects of probability of occurrence, possibility of prevention, priority of interventions and short term response to interventions. Post partum haemorrhage, labor management problems, and neonatal hypothermia got the highest scores in these regards, and then these 24 items were categorized in 2 groups of risk assessment and hospital management. Finally based on Risk Management Rules in Clinical Governance, the complications analysis was done with use of failure mode, effects analysis and practical strategies to decline obstetrical adverse events were suggested. Results: We understood all reported complications had common infrastructural problems: defects in Risk Assessment and Hospital Management Policies. We focused on basic infrastructural management in these 2 main subjects and in these two: our main problems were related to staff management and hospital management issues. Conclusion: Since managerial and staff dependent problems were our main problems, these two should be considered as our main priorities in risk management program.

Open Journal of Pediatrics (OJPed) , 2015, DOI: 10.4236/ojped.2015.54043
Abstract: Background: Respiratory distress syndrome (RDS) or hyaline membrane disease (HMD) is the most common cause of neonatal morbidity and mortality in preterm infants. We aimed to determine the frequency of RDS among 3 groups of preterm infants and the value of some related factors. Methods: A cross-sectional, descriptive analytical investigation was carried out in the NICU ward of Akbarabadi Hospital (Tehran-Iran) during spring 2011. Newborns’ data were collected and assessed by using their hospital medical records. Seventy-three preterm infants with gestational age < 34 weeks were hospitalized in the NICU. All participants were divided into 3 groups: extremely preterm (<28 weeks), very preterm (28 to <32 weeks) and moderate preterm (32 to 34 weeks). Frequency of RDS and some related factors were compared among 3 groups. Results: RDS was observed in 65.6% of all participants; however frequency of RDS was not different between three groups. An inversely correlation was found between gestational age and mortality rate (p = 0.05). In regard to Betamethasone administration prior to birth, this interval was significantly longer in alive neonates in comparison to infants who died (p < 0.05). Conclusion: RDS was frequent in preterm neonates with gestational age < 32 weeks. Time of Betamethasone administration prior to birth can significantly influence on neonatal mortality rate.

Abstract: Background: Myeloperoxidase staining is used to differentiate leukemias since several decades. Despite implementation of flow cytometric, cytogenetic and molecular techniques for identification of leukemic blasts, histochemical stains such as myeloperoxidase stain are persistently used for better classification of leukemias. The myeloperoxidase staining is a time consuming and hazardous procedure. The present report describes a sensitive, rapid and easy method for assessment of peroxidase activity. Materials and Methods: Bone marrow aspiration slides were stained with Dako product: Code number: K3467 containing DAB chromogen (3,3-diaminobenzidine in chromogen solution) and substrate buffer (Imidasole-HCL buffer, PH 7.5 containing hydrogen peroxide and an anti microbial agent) in a rapid procedure taking only ten minutes time. The staining needs no material preparation steps. Neutrophils in the slide are taken as positive control or another normal smear was costained to be used as control. All cases were followed up with flow cytometry and cytogenetic studies. Result: The reaction product of this stain is brown and granular. Promyelocytes and myelocytes are the most strongly staining cells with positive (primary) granules. Lymphoblasts are negative. The result of classification of leukemias with this technique was in concordance with flow cytometric immunophenotyping. Discussion: Many practical techniques have been described using benzidine as an indicator for myeloperoxidase staining. Benzidine is a carcinogenic material and its usage is severely restricted in laboratory. Formerly we prepared requisite materials for myeloperoxidase staining by hazardous ways (boiling), but we decided to apply ready to use 3,3-diaminobenzidine (DAB), which is used in final step of immunohistochemistry stains. Conclusion: Use of 3,3-diaminobenzidine (DAB) is highly recommended for myeloperoxidase staining, while the result is extraordinary and fully compatible with flow cytometry and the method is safe and rapid.

Abstract: A 34-year-old woman presented with tamponade and right pleural effusion. After drainage of pericardial and pleural fluid, Computed Tomography (CT) angio was done and massive effusion in lateral of Right Atrium (RA) was reported, but Transesophageal Echocardiography (TEE) revealed large intrapericardial mass with pressure effect on RA and Right Ventricle (RV), so thoracotomy was done and malignant carcinoma of thymus was reported. Malignant carcinoma of thymus has unusual presentations and cardiac involvement as first presentation is uncommon and should be considered.TEE has important role in recognizing and defining tumor.

Hayat Journal of Faculty of Nursing & Midwifery , 2012,
Abstract: Background & Objective: Hospitals and healthcare centers, like any other organizations, have some common norms and beliefs called as organizational culture. Organizational culture plays a key role in organization's and staffs' performances. Nurses' perspectives on the organizational culture affect the way they play their role in. This study aimed to investigate the role of organizational culture from perspectives of nurses working in selected hospitals at Tehran University of Medical Sciences. Methods & Materials: In this cross-sectional study, 230 nurses working in different wards of selected hospitals of Tehran University of Medical Sciences were recruited to the study. Data were collected using a demographic characteristics checklist as well as the nurse and organizational culture questionnaire extracted from the Robbins criteria. Data were analyzed using descriptive statistical indexes, independent t-test, Pearson correlation coefficient and regression in the SPSS v.17. Results: Results showed that the existing organizational culture in the selected hospitals was in a moderately good level from nurses' perspectives. From the scores obtained for various dimensions of the organizational culture, the highest and lowest scores were for control (44.2%) and conflict tolerance (31.8%), respectively. Conclusion: The level of the organizational culture from the nurses' perspectives might lead them to decrease the quality of their performance. Optimizing the organizational culture can improve nurses' performance and motivate them to increase their quality of work.

Abstract: Background: The implantable cardioverter defibrillators (ICDs) are increasingly being used as a treatment modality for life threatening tachyarrhythmia. The purpose of this study was to compare the frequency of complications and mortality between single-chamber and dual-chamber ICD implantation in Shahid Rajaie cardiovascular center. Methods and results: Between January 2000 and December 2004, 234 patients received ICD by a percutaneous transvenous approach and were followed for 33 ± 23 months. The cumulative incidence of complications was 9.4% over the follow-up period. There was no significant difference in overall complication rate between single chamber (VR) and dual chamber (DR) ICD groups in the follow-up period (P= 0.11). The risk of complications did not have any statistically significant difference in secondary versus primary prevention groups (P=0.06). The complications were not associated with the severity of left ventricular systolic dysfunction (P=0.16).The frequency of lead-related complications was higher in dual chamber ICDs in comparison with single chamber ICDs (P=0.02). There was no significant difference in mortality between different sex groups (P=0.37), different indications for ICD implantation (P=0.43) or between VR and DR ICD groups (P= 0.55). Predictors of mortality were NYHA class III or more (P<0.001), age >65 years (P=0.011) and LVEF<30% (P<0.001). The mortality in patients with CAD and DCM were significantly higher than those with other structural heart diseases (P=0.001). Conclusions: Close monitoring of patients during the first 2 month after ICD implantation is recommended because the majority of complications occur early after the procedure.

Abstract: Background and Aim: Learning disability(LD) is one of the most prevalent problems among elementary school children. Approximately 10 percent of all elementary school children suffer from this problem. It has been determined that learning disability is predominantly accompanied with subtle impairment in central auditory nervous system. The main idea of this study was to evaluate middle latency auditory evoked potential (MLAEPs) in learning disabled children. Materials and Method: This cross-sectional study investigated middle latency auditory evoked potential in children with learning disability (n = 31) compared to normal children (n = 31). Latencies and amplitudes of MLAEPs results with different stimulus intensity and binaural stimulation were compared between two groups. Results: Compared to control group, learning disabled children exhibited smaller amplitudes for all the components except the right ear Na and Pa. There is no significant difference between two groups for latencies of the components. Conclusion: It seems that middle latency auditory evoked potential may be useful in diagnosis and evaluation of learning disabled children although more investigation is required.
