Abstract

Bovine fibropapilloma and papilloma occur in different parts of the skin of animals. Bovine Papillomavirus (BPV) is an oncogenic virus making benign tumor lesion of together mucosal and cutaneous tissue in cattle. In order to confirm the clinical diagnosis; the study planned to make the molecular detection of BPV (DNA) using Polymerase Chain Reaction (PCR) from skin lesions and the phylogenetic analysis. Thirty-eight samples of skin lesions were collected from cattle clinically suspected to be infected with bovine papilloma virus from herds in Al-Qadisiyah Governorate in 2016, the primary clinical diagnosis depended on the morphological appearance and features of the lesion. Deoxyribonucleic Acid (DNA) was extracted from skin lesions; the DNA was examined by PCR technique using specific primer to BPV-1 /L gene-1. Twenty-two samples out of 38 (57,9%), which were collected from different regions in Al-Qadisiyah Governorate, were positive. The sequences of four positive samples of DNA product amplification of (BPV) type-1, L1 gene confirmed the PCR results. These samples had the DNA presented in four accession numbers KY662042-1, KY662043-1, KY662040-1 and KY662041-1. This study proofed that cutaneous bovine papillomatosis related with BPV-1 infection in the cattle herds has affinity to solid skin rather than other epithelial and mucosal tissue.

يحدث الورم الليفي الحليمي في أجزاء مختلفة من الجلد من الحيوانات، إن فيروس الثألول هو فيروس مسرطن يصنع آفة ورمية حميدة من الغشاء المخاطي والأنسجة الجلدية في الأبقار. تم إعداد هذه الدراسة للكشف الجزيئي للفايروس باستخدام تفاعل البلمرة المتسلسل من الآفات الجلدية المأخوذة من قطعان الأبقار في محافظة القادسية عام 2016. وثم تحليل التسلسل في هذه الدراسة حيث جمعت ثمان وثلاثين عينة من الآفات الجلدية في الأبقار التي يشتبه سريرياً بأنها مصابة بفيروس الورم الحليمي البقري، وقد اعتمد التشخيص السريري الأساسي على المظهر الشكلي وملامح هذه الآفة. تم استخراج الحمض النووي الرايبوزي من الآفات الجلدية، وتم فحص الحمض النووي عن طريق تقنية تفاعل السلسة المتبلمرة باستخدام بادئات محدد لجين BPV-1/L. كانت هناك اثنتان وعشرون عينة موجبة للفحص من أصل 38 عينة (بنسبة إصابة 57,89%) جمعت من مناطق مختلفة في محافظة القادسية. وقد أظهر تسلسل أربع عينات إيجابية من تضخيم حمض DNA للجين BPV type-1، L1 لتأكيد نتائج PCR. كانت هذه العينات تحمل الحمض النووي في أربعة أرقام مسجلة KY662042-1 و KY662043-1 و KY662040-1 و KY662041-1. وقد أثبتت هذه الدراسة أن الورم الحليمي الجلدي البقري المرتبط بالعدوى BPV-1 في قطعان الماشية له صلة بالجلد فقط بدلاً من الأنسجة الظهارية والأنسجة المخاطية الأخرى.

Abstract

background: A variety of non-neoplastic and neoplastic conditions involving the nasal cavity, paranasal sinuses, and nasopharynx. Most patients present with complaints of nasal obstruction. Other symptoms include nasal discharge, epistaxis, and disturbances of smell, oral symptoms, facial swelling, orbital symptoms, and ear symptoms. The presence of unilateral symptoms or pathology is regarded with caution as sinonasal neoplasms which may also present during their early stages with subtle symptoms that mimic an inflammatory pathology.Objectives: The aim of the study was to analyze the histopathologic diagnosis of patients with unilateral nasal mass and identify their different clinical presentations.Methods: A cross sectional prospective study was carried out on 34 consecutive patients with unilateral sinonasal mass at Al-Hussein Teaching Hospital and Maythem Al-Tammar Private Hospital, Karbala between April to August 2015 focusing on patient’s age, sex, and complaints. . Clinical examinations and proper investigations were carried out for all patients. Biopsy was taken from all cases for histopathologic examination to confirm diagnosis.Results: Out of total 34 patients with unilateral sinonasal masses 25 (73.5%) were males and 9 (26.5%) were females (M: F=2.8:1). The age range was 7 to 60 years with a mean age of 29.2 years. Twenty two patients were found to have non-neoplastic unilateral conditions (64.7%), while 12 patients had neoplastic unilateral conditions (35.3%). Inflammatory nasal polyp was the most common condition in non-neoplastic group (59.9%). Inverted papilloma was the commonest benign neoplastic condition (17.7%), 3 cases of non-Hodgkin’s lymphomas (8.9%) represents the commonest malignant neoplasms among malignant neoplastic group and single case of adenoid cystic carcinoma.Conclusions: Sinonasal masses have various differential diagnoses that otolaryngologists have to consider this variability in diagnosis and treatment. Nasal obstruction is the most common symptom while epistaxis and extranasal symptoms like facial pain, dental and orbital complaints were found to be higher in the neoplastic conditions. The clinician must have a high index of suspicion to rule out a neoplastic etiology in all cases of unilateral nasal mass.

Abstract

Background: Chronic obstructive pulmonary disease (COPD) is a common disease and it accounts for over 10% of all hospital medical admission. Cigarette smoking is the most important risk factor. Pulmonary arterial hypertension (PHT) is a common complication of COPD and the increase in pulmonary artery pressure is often mild to moderate. The presence of pulmonary arterial pressure and its severity is readily and reliably determined by transthoracic echocardiography in majority of COPD patients.
Patients and Methods: This study included 55 patients with mean age 65.6 ±8.2 years .The mean duration of symptoms was 18 ±10 months. 32 patients (58%) were current smoker, 18 patients (33%) were ex-smoker and 5 patients (9%) were non smoker. The mean intensity of smoking for smoker was 49.5 ± 22.2 pack- years. For all patients, history, clinical examination, ECG, CXR, and routine blood tests were done. For all patients pulmonary function tests were done and patients were classified according to GOLD criteria into 4 stages. Echocardiography was done for all patients; ventricular and atrial dimensions were taken, and using Doppler technique to detect tricuspid and pulmonary regurgitation, estimation of pulmonary artery systolic and/or diastolic pressure using special formulas was undertaken.Results: Tricuspid regurgitation (TR) jet was found in 70.9% of patients with COPD. Increased pulmonary artery systolic pressure was found in 51% of patients with TR (36% of total patients) and increased pulmonary vascular resistance was found in 48.7% of patients with TR (34.5% of total patients). There were significant associations between echo findings of increasing RV size, TR, increased pulmonary arterial pressure and pulmonary vascular resistance with decrease in FEV1, FEV1/VC and oxygen saturation. There was no significant association with decrease in vital capacity.Conclusions: There is a high prevalence of pulmonary arterial hypertension with increasing severity of chronic obstructive pulmonary disease.

Abstract

Background: Molecular DNA hybridization has confirmed more than 120 different human papilloma virus (HPV) genotypes. A small group of them have high- risk oncogenic potential. Many studies have described an association of such high risk-HPV genotypes with a variety of esophageal benign tumors as well as malignant squamous cell carcinomas.Patients and Methods: A total number of 90 tissue specimens were collected from 50 patients with esophageal squamous cell (SCC), adenocarcinoma (AC) and carcinoma in situ (CIS); 20 patients with squamous acanthosis (SA); and 20 individuals with apparently-healthy esophageal tissues (AHET). The molecular detection methods for HPV detection and genotyping were performed by in situ hybridization using cocktailed- and specific high- risk HPV DNA probes, respectively.
Results: The overall percentage of HPV in the total group of esophageal carcinoma was 20%.The percentage of HPV DNA in the subgroup of SCC and AC was 26.7% and 13.3%, respectively,. However, neither HPV DNA was detected in CIS subgroup nor in both control groups (SA and AHET).The overall genotyping results showed that HPV 18 constituted the majority of the detected high-risk oncogenic HPV genotypes, followed by HPV 16 then HPV 31/33.<.Conclusions: Despite the low prevalence of HPV infection and rarity of invasive esophageal carcinoma in the general Iraqi population, the detection of high percentage of such high oncogenic risk- HPV genotypes in these carcinomas indicating for a relevant importance in esophageal carcinogenesis.

Abstract

Summary:Background: Molecular DNA hybridization has confirmed more than 120 different human papilloma virus (HPV) genotypes. A small group of them have high- risk oncogenic potential. Many studies have described an association of such high risk-HPV genotypes with a variety of oral lesions including squamous cell carcinoma, leukoplakia, and lichen planus. .Materials and Methods: A total number of 42 tissue specimens, representing 27 patients with oral lichen planus and 15 apparently-healthy oral tissues, were included in this study. The molecular methods for HPV detection and genotyping were performed by in situ hybridization(ISH) using cocktailed- and specific high- risk HPV DNA probes, respectively.Results:The overall percentage of HPV in the total group of patients with oral lichen planus (OLP) was 33.3 %. Negative HPV DNA- ISH reactions were detected in all tissues of the control group. The overall genotyping results revealed HPV 16- DNA in all HPV- positive oral lichen planus tissues , while none of these OLP tissues showed ISH reactions for HPV 18-DNA or HPV 31/33-DNA.Conclusions: The significant incidence of such high oncogenic HPV genotype in those patients with oral precancerous lesions could have a relevant importance along its pathogenesis and the multi-steps oral carcinogenesis , HPV-16-associated oral lichen planus that has mostly previliged the site of cheek mucosa represents a herald indicator for spread of such sexually important transmitted infection among Iraqi general population.Key Words: Oral lichen planus; Human Papilloma Virus; In Situ Hybridization

Abstract

ABSTRACT:BACKGROUND:Among most basic and clinical investigations for detection and genotyping HPV, only In Situ Hybridization (ISH) is effective in studing the relation of HPV genome to that histopathological entity. Tumor Infiltrating Lymphocytes (TILs) represent the local cellular immune response against both cervical cancer and the associated HPV.OBJECTIVE:This study is aimed to investigate ISH in detection and genotyping of HPV and immunohistochemical (IHC) study in phenotyping of TILs in Iraqi women with different grades of cervical neoplasia.MATERIALS AND METHODS:This retrospective research included a total number of 129 cervical tissue blocks , 64 with invasive and 27 with pre-invasive cervical neoplasia,12 with condylomata acuminata,11 with chronic cervicitis and 15 with apparently- healthy cervices .Molecular detection and genotyping of HPV DNA were performed by using ISH whereas immunophenotyping was done by IHC using monoclonal antibodies for that specific CD markers representing some of TILs.RESULTS:The overall prevalence of HPV DNA in total group of invasive cervical neoplasia was 28.4% , 12 out of 48(25%) with squamous cell carcinoma(SCC) and 8 out of 16(50%) with adenocarcinoma (AC). HPV 16 constituted (58.3%) of HPV- positive invasive cervical SCC , where as HPV 31/33 and lastly HPV 18 constituted (25%) and (16.7%) , respectively .In AC group, HPV 16, 18, 31/33 occupied 50% , 25% , 12.5% of this group, respectively .The prevalence of HPV DNA in pre-invasive cervical neoplasia group was 22.2%. While no case with HPV 18 was detected , HPV 16 and HPV 31/33 genotypes occupied 40% and 60% , respectively .Although CD3+,CD4+and CD8+ lymphocytes showed high mean values , significant differences present only between HPV DNA- positive tissue blocks and control group (p<0.05) . The CD20+and CD56+ lymphocytes showed low mean values.Compared to control group,however,statistical analysis showed significant differences (p<0.05) regarding CD20+ and non-significant regarding CD56+ lymphocytes .CONCLUSION:Using ISH proved more powerful and sensitive tool in revealing precised effects of HPV in cervical neoplasia compared to histopathological examination .High mean values of CD4+ and CD8+ versus low mean values of CD20+ and CD56+ lymphocytes could reflect an important and specific role of these cellular responses against HPV viruses during initiation and progression of HPV-associated cervical cancers.

Abstract

Background: Via molecular DNA hybridization, more than 120 different genotypes of human papilloma virus havebeen confirmed. Many studies have described an association of high risk-HPV genotypes and overexpression ofmutated P53 gene with a variety of oral benign tumors as well as malignant squamous cell carcinomas. This studyaimed to: 1) Determine the prevalence of HPV DNA in archival tissue specimens with a range from apparentlyhealthy tissue to invasive oral S.C.C by using one of the recent versions of insitu hybridaization. 2) Define thegenotypes of the obtained HPV and to find out rational significance and relation of such genotypes to the severity ofunderlying lesions. 3) Study the correlation of over expressed products of mutant p53 genes with HPV-negative andHPV-related oral cancers.Materials and methods: A total number of 72 tissue specimens were collected from 41 patients with oral squamouscell (OSCC) and 31 individuals with apparently-healthy oral tissues (AHOT). The molecular detection methods for HPVdetection and genotyping were performed by in situ hybridization using cocktailed- and specified high- risk HPV DNAprobes, respectively. Immunohistochemical method was used to demonstrate the prevalence of P53 overexpressionin those oral cancers.Results: Among oral OSCC group, 16 archived tissue blocks were found to contain HPV DNA related to thecocktailed HPV genotypes. This result constituted 39% of the total oral SCC screened for HPV DNA. HPV-18 positiveoral SCC tissue blocks constituted (68.75%) whereas HPV genotypes 16& 31/33 constituted (43.75%) & (12.5%),respectively. Mixed infection of HPV genotypes was found in 31.3%. Interestingly, HPV DNA detection wasdocumented in 3.2% of those appeared as healthy tissues on histopathological examinations. Among oral SCCgroup, 22(53.7%) showed over expression of P53 tumor suppression gene. Interestingly, the co-occurrence of mutatedP53 overexpression and high oncogenic risk HPV genotypes was documented in 75% of Iraqi patients with OSCC.Conclusions: The significant prevalence of high oncogenic HPV genotypes detection in those patients with OSCCindicates a herald marks for the spread of such important sexually transmitted infection among Iraqi generalpopulation. Both of mutated p53 genes as well as high-oncogenic risk HPV genotypes could play an important role inoral carcinogenesis.
