We aimed to evaluate the frequency of various species among BSIs and SSIs at Tehran Heart Center, Tehran, Iran. Methods: Patients with localized or systemic infections that became evident 48 hours or more after hospitalization were included. Data were prospectively collected in 4 intensive care units (ICUs), 5 cardiac care units (CCUs), 7 post-CCUs, and 5 surgical wards during two consecutive years in 2008 and 2009. Approximately 18414 coronary angiography and 7393 open-heart surgeries were done within this period. Antimicrobial susceptibility testing was performed by the Kirby–Bauer disk diffusion method, in accordance with the Clinical and Laboratory Standards Institute (CLSI) guidelines. Results: Among 212 detected patients with SSI and/or BSI in the year 2008, 138 had hospital acquired infection (HAI) and 74 had non–HAI while these figures for 2009 was 165/270 and 105/270, respectively. <em>Staphylococcus aureus</em> (21.5%) and <em>Entrobacter </em>spp<em>.</em> (16.5%) were two most common pathogens responsible for hospital acquired BSIs while <em>S. aureus</em> (20.6%) and <em>S. epidermidis</em> (20.6%) were corresponding isolates responsible for community acquired BSIs. <em>Staphylococcus aureus</em> (53.3%) and <em>Escherichia coli</em> (11.0%) were the two most common pathogens responsible for hospital acquired SSIs in the year 2008, while <em>S. aureus</em> (49.0%) and <em>S. epidermidis</em> (11.0%) were the most frequently reported hospital acquired SSIs in 2009. Conclusions: Making rational decisions about hospital infection control plans may reduce infection rates for bacteria with antimicrobial resistance. https://ijp.iranpath.org/article_8246_fa77afcb5ca08c4683a86127c9c0a766.pdfFarname Inc in collaboration with Iranian Society of PathologyIranian Journal of Pathology1735-53038420131001Diagnostic Accuracy of Frozen Section in Comparison With Fine Needle Aspiration Cytology in Thyroid Lesions – A Prospective Study2192268247ENMahesh KumarDept. of Pathology Pratima Institute Medical Sciences, Karimnagar, A.P , IndiaRatnakar PotekarDept. of Pathology, BLDE University’s Shri BM Patil Medical College, Bijapur , Karimnagar, IndiaBalasaheb Ramling YelikarDept. of Pathology, BLDE University’s Shri BM Patil Medical College, Bijapur , Karimnagar, IndiaVijayalaxmi PatilDept. of Pathology, BLDE University’s Shri BM Patil Medical College, Bijapur , Karimnagar, IndiaMahesh KarigoudarDept. of Pathology, BLDE University’s Shri BM Patil Medical College, Bijapur , Karimnagar, IndiaPankaj PandeDept. of Pathology, BLDE University’s Shri BM Patil Medical College, Bijapur , Karimnagar, IndiaJournal Article20121215Background and Objectives: Thyroid gland because of its superficial location is amenable to direct physical examination. Clinical assessment of thyroid lesions by means of physical examination, thyroid scans and ultrasonography is not completely reliable. Fine needle aspiration cytology (FNAC) is the most cost-effective, safe and an initial diagnostic test in the pre-operative evaluation of thyroid lesions. Many surgeons use intraoperative frozen section biopsies to confirm the diagnosis of FNAC and guide the extent of thyroidectomy. Therefore, the objective of the present study was to assess the diagnostic accuracy of frozen section in comparison with fine needle aspiration cytology and histopathology in thyroid lesions.
Materials & Methods: Fine needle aspiration cytology and frozen section (FS) were evaluated in 59 patients. FNAC was classified as benign, malignant and suspicious, and FS was classified as benign, deferred and malignant. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy were calculated for both FS and FNAC.
Results: Out of 59 patients, 3 were positive for malignancy, 51 were benign, and five were suspicious on FNAC. Over all accuracy of fine needle aspiration cytology was 93%. Five were positive for malignancy, 50 were benign and 4 were “deferred” in frozen section. Over all accuracy of frozen section was 96%.
Discussion: Fine needle aspiration cytology can be used primarily to select patient for surgery and frozen section can be employed to plan the extent of surgery. Frozen section had a good accuracy, sensitivity and negative predictive value compared to fine needle aspiration cytology.

The ‛squash’ or ‛crush’ technique has been universally employed in the intraoperative diagnosis of CNS tumors. The aim of our study was to evaluate the accuracy of squash preparation in diagnosing CNS tumors by comparing with histopathology.
Methods: This was a descriptive study which included 63 patients with CNS tumors from whom most of the samples were collected by craniotomy. Squash smears were made and stained with H&E, Papanicolaou & May-Grunwald Giemsa stains. Paraffin sections were made from formalin fixed tissue sent separately.
Results: Of 63 cases, squash cytology diagnosis correlated with histopathology in 56 cases with a diagnostic accuracy of 88.9%. A 100% accuracy was seen in pilocytic astrocytoma, anaplastic astrocytoma, glioblastoma, ependymoma, anaplastic ependymoma, choroid plexus papilloma, schwannoma, hemangioblastoma, craniopharyngioma, prolactinoma and metastases. Of the 7 cases which did not correlate with histopathology, one was a sampling error, 4 were diagnostic errors and 2 were instances of grading discrepancy.
Conclusion: Squash preparations are a highly effective tool in the rapid intraoperative diagnosis of CNS tumors. It is a simple, reliable, cost effective procedure which in most cases can help the operating surgeon to come to a correct decision regarding the further management of the patients.

We investigated the incidence of COX-2 expression in patients and assessed interactions between COX-2 and clinical features of cancer and expression of HER2/neu, estrogen receptor (ER), and progesterone receptor (PR).
Methods: COX-2 expression was investigated by immunohistochemistry in 29 patients’ specimens diagnosed as primary breast cancer between 2006 and 2008 at the Fatemieh Hospital, Semnan, Iran. Relationship between COX-2 expression and age, histological grade, histological type, nodal status, and hormone receptor status were evaluated.
Results: We used IHC method although it was not a quantitative study. Its expression depends on quality of antibody, staining and selection of analyzed region. COX-2, HER-2, ER, and PR were detected in 89.7%, 51.7%, 82.8%, and 79.3% of samples, respectively. Elevated COX-2 expression was not associated with size and grade of tumor, while mean numbers of involved lymph nodes was significantly higher in those with elevated expression of COX-2 (<em>P</em> = 0.001). There were no significant correlations between COX-2 expression and HER-2, ER, and PR receptors.
Conclusion: Only tumor tissue was analyzed and did not compare to normal tissue. Elevated COX-2 expression can be found in most patients with breast cancer and has a crucial role in tumor differentiation regarding degree of lymph node involvement. It seems that correlation between COX-2 and other oncogens and hormonal receptors might be influenced by geographical and racial factors, so, assessment of these relationships in each patient's population may be necessary.

Fine needle aspiration biopsy (FNAB) is one of the methods of breast biopsy which is fast, easy and cost effective. The aim of this study was to evaluate the concordance rate between pathologic results of sonography or stereotaxy guided FNAB and guided core needle biopsy (CNB) in the evaluation of breast lesions.
Materials & Methods: During December 2010 until March 2011, 36 female patients with 37 breast lesions referred to FNAB and CNB with the guide of sonography in 35 lesions and with the guide of stereotaxy in 2 lesions. The kappa statistic used to calculate the concordance coefficient.
Results: The concordance rate between guided – FNAB and guided – CNB was 93% with using kappa coefficient. In 5 patients, subjected to breast surgery, malignancy was reported as well as in guided-FNAB or guided-CNB.
Conclusion: Because of high concordance between these two techniques in the assessment of breast lesions, guided FNAB is recommended in the first step. Guided-CNB can be reserved for lesions with insufficient pathology results by guided-FNAB.https://ijp.iranpath.org/article_8250_bde83401b8f1bb18fdeea1e250215392.pdfFarname Inc in collaboration with Iranian Society of PathologyIranian Journal of Pathology1735-53038420131001DNA Load Analysis Using Real Time PCR In Comparison With Immunohistochemical Findings of Dry Type Cutaneous Leishmaniasis; Before and After Treatment by Imiquimode,Glucantime and Combination of Both Drugs2472548251ENShahriar DabiriDept. of Pathology, Leishmania Research Center, Afzalipour Medical School, Kerman University of Medical Science, Kerman, Iran0000-0002-5922-3976Hassan Manafi AnariDept. of Pathology, Afzalipour Medical School, Kerman University of Medical Science, Kerman, IranSimin Shamsi MeymandiDept. of Dermatology, Afzalipour Medical School, Kerman University of Medical Science, Kerman, IranReza Fotouhi ArdakaniDept. of Biotechnology, Pasteur Institute of Iran, Tehran, Iran & Shahid-Sadoughi University of

This study was conducted to compare the effect of different treatments on parasite DNA load following therapies using Real-Time PCR method.
Materials and Methods: Fifteen patients were divided into three groups under therapy with intralesional meglumine antimoniate, topical imiquimod and combination of both drugs. After obtaining consent from patients, punch biopsies were taken before and after treatment .To compare the amount of DNA load a relative quantitative Real-Time PCR method was designed and set up using <em>Leishmania tropica</em> ITS (internal transcribed spacer) gene. After doing PCR, the obtained results were analyzed using 2^-ΔΔC<sub>T</sub> method and relativity of DNA load before and after treatment were calculated.
Results: The highest falling of DNA load was for imiquimod (mean 4/7 cases), glucantime (mean 2/2 cases) and combination therapy (mean 2/4). From clinical point of view combination therapy had the best response. On the other hand, the overall IHC findings showed good response based on decreased CD1a epidermal, increased CD1a dermal, decreased CD68 macrophages and increased CD3 and CD20 of dermis.
Conclusion: We set up a new method to compare <em>Leishmania</em> DNA load using the stable human gene of beta actin for normalization. We concluded that imiquimod was immune modulator and had synergistic effects on the best parasitocidal drug of glucantime for better response.

In this study establishment of immunohistopathological changes of dendritic cells and other immune effector cells in lupus nephritis comparing with non-lupus nephritis was performed.
Materials & Methods: Renal needle biopsies of 35 cases of lupus nephritis and 35 cases of other causes of persistent proteinuria were compared for immunohistochemistry for plasmacytoid (CD123), myeloid (CD11c) dendritic cells, macrophages (CD68) and lymphocytes (CD4) markers. Statistical analysis of the data was performed using Spearman and Pearson correlation or ANOVA and <em>t</em>- student test (<em>P</em> < 0.05).
Results:Significant difference of glomerular and interstitial spaces for presence of myeloid-plasmacytoid dendritic cells and lymphocytes except macrophages between lupus nephritis and other causes of persistent proteinuria have found (<em>P</em><0.001). Positive significant correlations were observed between glomerular presentation of myeloid dendritic cells and chronicity index but not with other markers in lupus nephritis (<em>P</em> <0.001). Statistically significant changes between presence of all markers and activity index were not observed (<em>P</em> >0.05).
Conclusions<em>:</em> The myeloid dendritic cells might have synergistic role with other immune cells in pathogenesis and progression or chronicity of lupus nephritis.https://ijp.iranpath.org/article_8252_f6910978fbf5381b9122bd9a3a0b46bc.pdfFarname Inc in collaboration with Iranian Society of PathologyIranian Journal of Pathology1735-53038420131001Pedunculated Chorangioma of Placenta - an Extremely Rare Case Report2632668253ENJawahar RamasamyDept. of Pathology, Pondicherry Institute of Medical Science, Pondicherry, IndiaRenu G’Boy VargheseDept. of Pathology, Pondicherry Institute of Medical Science, Pondicherry, IndiaJournal Article20120725Pedunculated chorangioma is extremely rare type of chorangioma.

Patients usually present with sudden onset multiple nodules and plaques, most often involving the skin and subcutaneous tissue of trunk and lower limbs. Here we report an unusual case of de novo (without any history of prior anti-leprotic therapy) HL, arising as multiple nodules in the face. The histopathology of the lesion showed collection of spindled macrophages in the dermis, oriented in a storiform-like pattern. A possibility of HL was considered and the diagnosis was confirmed by performing a modified ZN stain (Wade-Fite stain) on the biopsy material, which revealed the presence of acid-fast bacilli (AFB) with a bacillary index of 6. Then the patient was put on multibacillary multi-drug chemotherapy and was thereby cured.
