ABSTRACT Hoarseness of voice is one of the commonest symptoms found in ENT clinics. The present study is to assess etiopathology of hoarseness of voice at our center. The diagnostic potential of laryngeal endoscopy for different laryngeal lesions and its correlation with histopathology is also done. In this retrospective study 126 patients were included. The commonest etiology for hoarseness of voice was found to be chronic laryngitis (51.6%) followed by malignancy (27.8%) and vocal cord paralysis (15.1%). Vocal abuse (33.3%) and smoking (29.4%) were found to be leading predisposing factors. Positive predictive value of laryngeal endoscopy for detecting malignant lesions was found to be 86.5%. Fibreoptic laryngoscopy is a good tool for preliminary evaluation of hoarseness of voice. However, direct laryngoscopy should not be delayed if a diagnosis cannot be made by fibreoptic laryngoscopy KEYWORDS Hoarseness, Laryngeal endoscopy, Voice, Etiolopathology

This prospective study was done in the Department of Radio diagnosis Govt. Medical College, Kozhikode. A total of 65 patients who were referred to our department with clinical suspicion of endometrial lesions and incidentally detected endometrial lesions on ultrasonography underwent transvaginal ultrasound and subsequent Imaging evaluation of pelvis MRI has very high sensitivity (95%) and specificity (98%) and is almost as accurate (97%) as histopathology in differentiating benign from malignant lesions. Addition of DWI with ADC mapping to conventional MRI increases its accuracy even more. However there is inherent limitation to MRI in detecting carcinoma in situ and micrometastasis.

Improvements in multislice computed tomography (MSCT) angiography of the coronary vessels have enabled the minimally invasive detection of coronary artery stenoses, while quantitative coronary angiography (QCA) is the accepted reference standard for evaluation thereof. Sixteen-slice MSCT showed promising diagnostic accuracy in detecting coronary artery stenoses haemodynamically and the subsequent introduction of 64-slice scanners promised excellent and fast results for coronary artery studies. This prompted us to evaluate the diagnostic accuracy, sensitivity, specificity, and the negative und positive predictive value of 64-slice MSCT in the detection of haemodynamically significant coronary artery stenoses. Thirty-seven consecutive subjects with suspected coronary artery disease were evaluated with MSCT angiography and the results compared with QCA. All vessels were considered for the assessment of significant coronary artery stenosis (diameter reduction ≥ 50%). Thirteen patients (35%) were identified as having significant coronary artery stenoses on QCA with 6.3% (35/555) affected segments. None of the coronary segments were excluded from analysis. Overall sensitivity for classifying stenoses of 64-slice MSCT was 69%, specificity was 92%, positive predictive value was 38% and negative predictive value was 98%. The interobserver variability for detection of significant lesions had a κ-value of 0.43. Sixty-four-slice MSCT offers the diagnostic potential to detect coronary artery disease, to quantify haemodynamically significant coronary artery stenoses and to avoid unnecessary invasive coronary artery examinations.

Abstract Background There are many causes of pleural disease including variable benign and malignant etiologies. DWI is a non-enhanced functional MRI technique that allows qualitative and quantitative characterization of tissues based on their water molecules diffusivity. The aim of this study was to evaluate the diagnostic value of DWI-MRI in detection and characterization of pleural diseases and its capability in differentiating benign from malignant pleural lesions. Results Conventional MRI was able to discriminate benign from malignant lesions by using morphological features (contour and thickness) with sensitivity 89.29%, specificity 76%, positive predictive value 89%, negative predictive value 76.92%, and accuracy 85.37%. ADC value as a quantitative parameter of DWI found that ADC values of malignant pleural diseases were significantly lower than that of benign lesions (P < 0.001). Hence, we discovered that using ADC mean value of 1.68 × 10-3 mm2/s as a cutoff value can differentiate malignant from benign pleural diseases with sensitivity 89.3%, specificity 100%, positive predictive value 100%, negative predictive value 81.2%, and accuracy 92.68% (P < 0.001). Conclusion Although DWI-MRI is unable to differentiate between malignant and benign pleural effusion, its combined morphological and functional information provide valid non-invasive method to accurately characterize pleural soft tissue diseases differentiating benign from malignant lesions with higher specificity and accuracy than conventional MRI.

Abstract Background Asymmetric breast density is a potentially perplexing finding; it may be due to normal hormonal variation of the parenchymal pattern and summation artifact or it may indicate an underlying true pathology. The current study aimed to identify the role of diffusion-weighted imaging (DWI) and the apparent diffusion coefficient (ADC) values in the assessment of breast asymmetries. Results Fifty breast lesions were detected corresponding to the mammographic asymmetry. There were 35 (70%) benign lesions and 15 (30%) malignant lesions. The mean ADC value was 1.59 ± 0.4 × 10–3 mm2/s for benign lesions and 0.82 ± 0.3 × 10–3 mm2/s for malignant lesions. The ADC cutoff value to differentiate between benign and malignant lesions was 1.10 × 10–3 mm2/s with sensitivity 80%, specificity 88.6%, positive predictive value 75%, negative predictive value 91%, and accuracy 86%. Best results were achieved by implementation of the combined DCE-MRI and DWI protocol, with sensitivity 93.3%, specificity 94.3%, positive predictive value 87.5%, negative predictive value 97.1%, and accuracy 94%. Conclusion Dynamic contrast-enhanced MRI (DCE-MRI) was the most sensitive method for the detection of the underlying malignant pathology of breast asymmetries. However, it provided a limited specificity that may cause improper final BIRADS classification and may increase the unnecessary invasive procedures. DWI was used as an adjunctive method to DCE-MRI that maintained high sensitivity and increased specificity and the overall diagnostic accuracy of breast MRI examination. Best results can be achieved by the combined protocol of DCE-MRI and DWI.

New Finding

A ten-year retrospective study has been undertaken on a group of ten haemophiliacs for whom previous haematological and radiological data was available. Radiological and clinical assessment of their knees and elbows (40 joints) have been correlated to the accurate recording of all haemarthroses suffered by these joints. There is a statistically significant association between the number of haemarthroses and the radiological change in the joint, as determined by a radiological scoring system. The knees, but not the elbows, show a significant association between number of haemarthroses and deterioration in clinical function. Several bleeds can occur in a haemophilic joint without necessarily causing permanent radiological change; this new finding in adults may be due to modern therapy.

The Mean

Objective: This study aims to determine the incidence, age, gender, sites and histological patterns of pediatric and adolescent oral lesions in a Sudanese population. Methods: A 7-year (2011 to 2017) retrospective analysis of pediatric and adolescent oral lesions in children younger than 18 years was carried out in Prof Ahmed Sulieman histopathology laboratory at the faculty of dentistry, university of Khartoum Results: within the study period, there were 479 pediatric and adolescence patients. There was male predilection for the lesions (53.9%). The mean age was 11.59±4.219 years. The mandible (n=139, 29%), followed by the maxilla (n=131, 27%) were the most common sites. The benign tumors (n=181, 37.7%) the most common lesions, and ameloblastoma was the commonest benign lesion. Conclusion: the results of the current study are in agreement with those reported in the literature concerning the most prevalent lesions in the pediatric and adolescence population. Most lesions were benign, and malignant lesions comprise only a very small part of the sample.
