Introduction: Anthracosis is known as the black lung disease and studies have shown relationships between the disease and lung carcinoma. In addition, the expression of CDH1 and EGFR genes can be used as the prognostic of anthracosis. The present study surveys the expression of CDH1 and EGFR genes in anthracosis patients and its relationship with non-small cells lung carcinoma. Methodology: Thirty anthracosis patients diagnosed by a specialist participated in the study. The subjects were asked to sign an informed letter of consent and then, to examine the expression of CDH1 and EGFR genes through real-time PCR, tissue samples were collected. Afterward, the relationship of expression of the biomarkers with tumor staging and cancer progress was examined. Results: Mean age of the patients was 48±10.5 years. As the reference gene, 18sRNA was adopted and comparison of mean CTs at the center and edges of lesions showed no significant difference. As to CDH1 gene at the center of lesions, 12 cases out of 30 were positive, which indicates 40% sensitivity; while at the edges, 20 cases out 30 were positive. Comparison of the positive rates of CDH1 gene at the center and edges of the lesions indicated a significant difference (P-value<0.001). Moreover and with regard to EGFR gene at the center of lesions, 19 cases out 30 were positive (sensitivity = 63.3%) and five cases out of 30 were positive at the edges of lesions (control). There was also a significant difference between the positive cases of EGFR gene at the center and edges of the lesions (P-value<0.001). Clearly, the positive cases of CDH1 at the edges were higher than that at the center, while in the case of EGFR gene, positive cases at the center were higher than that at the edges. It is notable that to obtan results with higher accuracy entails increasing the sensitivity level. Following similar studies and to have higher accuracy, the experiments were carried out with three iterations. Conclusion: In general, the results indicated a sort of relationship between anthracosis and lung carcinoma. To prove such relationship on a more solid ground, more studies with larger number of subjects are needed.

Introduction and objective: Anthracosis is a pneumoconiosis caused by coal dust. The term “pneumoconiosis” refers to an occupational lung disease caused by long-term inhalation of dust. To achieve more efficient diagnosis and treatment methods, changes in the expression of MUC1 and P16 genes in the patients with anthracosis and their relationship with none-small cells lung carcinoma were examined. Methodology: Thirty anthracosis samples (center of lesion) and thirty healthy samples (edges of lesion) were collected from anthracosis patients diagnosed by a specialist. The patients signed a written letter of consent beforehand. The expression of MUC1 and P19 biomarkers was measured through Real-Time PCR. The relationship of the expression of biomarkers with tumor staging and lung carcinoma stage was examined. Results: The two groups in the study were compared using t-test. P16 marker was positive at the center and edges of lesions in seven (out of 30) and 18 (out of 30) cases respectively. There was a significant difference between positive P16 markers at the center and edges of the lesions (p-value<0.001). MUC1 marker was positive at the center of lesions in 21 cases out of 30 (sensitivity = 70%) and it was positive at the edges of lesions in seven cases out of 30. In terms lesions (p-value<0.001). Conclusion: The results indicated a relationship between anthracosis and lung carcinoma. Clearly, the positive cases of P16 genes at the edges of lesions were higher than that at the center; while, the positive cases of MCU1 gene at the center of lesions were higher than that at the edges. Further studies with larger sample groups are needed to provide more evidences.

The study was designed to investigate the relationship of psychological well-being with depression and anxiety among heart patients.1 For this purpose, a sample of 200 patients was taken, including 100 men and 100 women, educated uneducated, employed and unemployed volunteers. The sample was taken from Nishtar Hospital, Combined military hospital and other private hospitals in Multan. The age range from 25 to 60 (mean age 43.085).2,3 Objective: To observe the effect of demographic variables (age, education, gender and source of finance) on psychological well-being and depression, anxiety in heart patients. Methods: 1. Low psychological well-being would be positively correlated with depression and anxiety. 2. Older age (above 50) heart patients would have low sense of psychological well-being as compared to younger age (above 35) heart patients. Results: Different statistical procedures were used to determine the relationship of psychological well-being with depression and anxiety among heart patients. Correlation was computed to see the relationship among variables. It was found that there is negative correlation between psychological well-being with depression and anxiety. Since the p-value in less than α (p-value < 0.01), so we reject null hypothesis Ho, and conclude that low psychological well-being is positively correlated with depression and anxiety. Conclusion: This study also finds out important findings on the role of stresses, feeling of worthlessness in depression and anxiety disorder. It is concluded that psychological well-being, depression and anxiety are not significant correlated with each other. Source of income or job and sex of the heart patients have significant effect on psychological well being. However there is no significant difference between men and women regarding the rate of depression and anxiety. Keywords: P-Value, Correlation, Null Hypothesis , Depression

Background: Black dust deposited in the lungs is called anthracosis. By damaging bronchial mucosa, anthracosis can affect the mucociliary cleaning function. Initial reports indicate that there is a relationship between anthracosis and pulmonary tuberculosis. Due to obstructive effects of anthracosis on distal airways and disruption in a proper sampling of bronchoalveolar lavage (BAL), other diagnostic methods are necessary for estimating the tuberculosis prevalence in these patients. The aims of this study was to evaluate tissue samples adjacent to an anthracotic plaque for acid-fast bacilli smear and culture. Methods: his is a cross-sectional analysis study on 100 patients referred to Shahid Sadoughi Hospital who required bronchoscopy and anthracotic plaque based on bronchoscopy results. Bronchial fluid lavage, two biopsy samples for culture, and a smear of Mycobacterium tuberculosis from the surrounding of these plaques were prepared. Data analyses were carried out using SPSS (version 18). Results: One-hundred patients og the age range 46-91years were studied. The patients with tuberculosis diagnosis based on the smear of BAL and bronchial tissue samples and culture of BAL and bronchial tissue samples were 7%, 13%, 6% and 8% respectively. The presence of granuloma in histopathology was seen in 15 patients infected with tuberculosis. (κ > 0.04, p-value <0.05). In patients with positive tuberculosis, culture of bronchoalveolar lavage was superior to other methods. Conclusions: Diagnostic value of BAL method and tissue biopsy in anthracosis patients with tuberculosis did not show a statistically significant difference. As compared with other methods, BAL culture was more positive. Therefore, tissue biopsy is not a good alternative to BAL.

Objectives: Cancer is one of the main causes of death in the world. Changes in the expression of CK19 and CEA genes in peripheral blood of OSCC patients were examined for early diagnosis. Methodology: The participants were 36 patients and 36 normal individuals. CK19 and CEA of blood serum were measured through Real-Time PCR. The relationship of the biomarkers with tumor staging and cancer development was examined. Results: Comparison of the two groups of participants using t-test indicated no significant difference in terms of mean age. CK19 marker was positive in 19 participants of the patients group (n=36), which meant the sensitivity of the marker was 53%. In addition, the marker was positive in eight participants of the normal group (n=36). CEA marker was positive in 26 participants of the patients group (n=36), which meant the sensitivity of the marker was 72%. Moreover, the marker was positive in 11 participants in the normal group (n=36). Conclusion: In general, the study introduced a screening test for early diagnosis of OSCC. To have evidences with more reliability, future studies should be carried out with larger sample groups.

Background: Neonatal hyperbilirubinemia is a common problem in neonates with an incidence of about 60% in term babies and 80% in preterm babies. It is the commonest cause of admission to the hospitals in the newborn period. Studies comparing the correlation between total serum bilirubin (SBR) and transcutaneous bilirubin (TcB) have yielded different results. So, we planned this study to find out relationship between TcB and SBR values.Methods: A hospital based prospective study was done during March 2016 to September 2016, in which a total of 120 newborns including term and preterm who were admitted with neonatal jaundice in NICU, Maharana Bhupal Hospital, Udaipur, Rajasthan were assessed in terms of age, sex and weight and investigated for both TcB and SBR. The sample size was calculated at a confidence interval of 90% and allowable error of 15%.Results: Out of total 120 study subjects, 59 (49%) were males and 61 (51%) were females, out of which 53 (44%) were preterm and 67 (56%) were term neonates. Mean TcB and SBR values at the time of admission has a mean difference of 2.52 mg/dl with a p-value <0.001 (significant) on the other hand TcB and SBR at 24 hr of admission has a mean difference of 1.57 with a p-value >0.001, which is non-significant. TcB and SBR at 48 and 72 hr of admission also has a mean difference which is also non- significant (p >0.001).Conclusions: From present study, we conclude that there is no significant difference between TcB and SBR values at 24, 48 and 72 hrs after starting phototherapy. The values of TcB are equally reliable as SBR values.

Abstract Background to evaluate the distribution of lingual foramina (LF) and their correlation with demographic characteristics and mandible width in a series of patients subjected to cone-beam CT (CBCT). Methods CBCTs were reviewed to assess the number of all LF, midline and lateral LF. We also assessed the relationship of the number of lateral LF with gender and mandibular width using the Chi Square test. A p value < 0.05 was considered statistically significant. Results 300 patients (180 males; age range: 21-87years) were included. The highest frequency per patient was of 2 LF (97/300, 32.3%), followed by 3 (81/300, 27%) and 4 (53/300, 17.7%). No LF were observed in 2/300 patients (0.7%), while the highest number was of 8 LF in one patient. The highest frequency of midline LF per person was of 2 LF (57.3%, 172/300), while the highest number per person was 5 LF in one patient (0.3%). The highest frequency of midline LF located above and below the genial tubercle was of 1 in 197/300 patients (65.7%) and in 169/300 patients (56.3%), respectively. Concerning lateral LF, the highest frequencies were of 0 (113/300, 37.7%) and of 1 (112/300, 37.3%). We did not observe any significant difference of the number of midline and lateral LF based on gender (P = .438 and P = .195, respectively) or mandible width (P = .069 and P = .114, respectively). Conclusions We have shown the high variability of number and anatomic distribution of LF in an Italian group of patients subjected to CBCT without reporting any association with gender and mandible width.

Abstract Abstract: Background: Head and neck Tumour (HNT) are tumour of the paranasal sinuses, the salivary glands and the upper aero¬digestive tract. EGF can stimulate cell proliferation, cell differentiation, cell growth, migration, and inhibit apoptosis. The aim of this study was to investigate the expression of EGFR in head and neck tumour. Method: EGFR expression was analyzed using quantitative real-time PCR (qRT-PCR) and immunohistochemical staining on tissue samples from a consecutive series of 150 head and neck tumour patients who underwent tumor resections between 2014 and 2018. Results: The relationship between EGFR expressions, clinicopathological factors, was investigated. qRT-PCR results showed that the EGFR expression was high in tumor tissue samples than in the normal head and neck tissues. High and low EGFR was compared with ages ≤40,>40 in the head and neck cancer of p- value 0.03. There was a significant difference between the histological differentiation of the malignant tumour with p values of 0.001, when well, moderate and poor was compared. There was a significant difference (p-value 0.012) between the I-II and III-IV tumour stages when the high level and low expression of EGFR were compared. Conclusion: Our data suggest that EGFR plays an important role in head and neck tumour progression and that its expression will provide baseline data to facilitate identification of new molecular targeting therapeutics. Keywords: EGFR, Head and neck tumour, Clinicopathological factors.
