Penile doppler ultrasound provides real-time evaluation of cavernosal vascular flow dynamics. Purpose of our study was to evaluate and compare the baseline penile ultrasound and color doppler vascular parameters in patients of ED to see if there was any significant difference between patients of psychogenic and vasculogenic ED (diagnosed on post Papaverine injection color doppler) without the use of intracavernosal Papaverine injection. To best of our knowledge such detailed comparison of baseline penile ultrasound and doppler parameters have not been published in literature. Methods: We have prospectively studied 32 patients of ED who underwent ultrasound, and color doppler pre-and post-papaverine intracavernosal injection. Baseline pre papaverine diameters of right and left cavernosal arteries were measured on grey scale ultrasound. Peak systolic velocity (PSV), end diastolic velocity (EDV) and resistive index (RI) of right and left cavernosal arteries were measured on color doppler before and after injecting intracavernosal papaverine injection. Patients were divided into normal study group (psychogenic ED), arterial insufficiency and venous leakage groups (vasculogenic ED) on the basis of post papaverine color doppler findings. Results: Eighteen patients showed normal study, 11 showed arterial insufficiency and 3 patients had venous leakage on post Papaverine injection color doppler. When base line prepapaverine vascular diameters and color doppler parameters were compared statistically, no significant difference was detected between and within these study groups. We have also compared Ed duration and IIEF scores among various study groups and found statistically significant difference between and within the groups. Conclusion: Use of a vasoactive agent like Papaverine with color Doppler is must to diagnose the vasculogenic ED.","PeriodicalId":14010,"journal":{"name":"International Journal of Medical and Dental Sciences","volume":"15 1","pages":"1981-1994"},"PeriodicalIF":0.0,"publicationDate":"2021-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89346874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results of surgical repair are disappointing with recurrence rates of suture repair being in the range of 5–63% depending upon the type of repair used, with better results using mesh implantation. In extreme cases a large hernial defect exists with a “loss of abdominal domain”. In addition, the approximated rectus muscles under tension become hypoper fused leading to atrophy and increased chances of recurrence. For the management of such large hernias, interest has been generated in the “ Component Separation Technique ”. This technique relaxes abdominal wall by translation of muscular layers without severing the innervation and blood supply, with or without the mesh augmentation. This can accommodate for defects up to 25–30cm in the waistline. However, wound complications are frequent and reported in up to half of the patients. Thus, the study was planned in view of the potential benefits of “CST” and its capability to restore lost abdominal domain. Methods: The study was conducted on 20 patients with “Large Incisional Hernia” with defect size >5cm or with a surface area >50cm 2 operated upon with component separation. Outcome was measured over a follow up period of three months in terms of recurrence and other local complications. Result: There were 20 patients [3 men and 17 women; 70% cases above the age of 50years]. Mean defect size was 9.5cm [range = 6–20cm]. Average body mass index was 28.97kg/m 2 [range = 22–37kg/ m 2 ]. Mean duration of hospital stay was 9 days [range = 5–21 days]. Early complications occurred in 15% (3/20) cases and post-operative abdominal compartment or recurrence was not reported over a follow up period of 3 months.

Materials and Methods: 232 dental students from 4 colleges in North India completed a survey comprising 11 polar questions about their perception of contemporary restorative dental practice and their curriculum update regarding the same. Further, the collected data was tabulated and finally extracted data was subjected to descriptive analysis using Chi-square test. Results: All 11 questions showed statistically significant responses. Only 15.5% of students thought that the current curriculum of restorative dentistry was adequate. Moreover, only 20.7% of the respondents were confident about using rubber dam for isolation. About 93.1% felt that the quality of their composite restorations was not at par with those seen on social media. A clear majority of 91.4% felt that the maximum uploads of restorative dentistry involved composite restorations. A huge number of 91.45% did not use rubber dam for isolation in composite restorations. 79.3% students felt that the current curriculum is not teaching them about the various instruments, and developing their skills about instrumentation and operative procedures of composite restorations matching the trending composite practices.

Localized infections sometimes progress to systemic infections, while ‘spontaneous’ bacteraemia also occur without an evident septic focus, particularly in chronic debilitated immunocompromised patients. Emergence of drug resistance to penicillins and penicillinase-resistant penicillins (i.e., oxacillin and methicillin) is a globally recognized problem. Methicillin Resistant Staphylococcus aureus isolates are also important with respect to the range of nosocomial infections it causes, leading to an increase in the hospital expenditure and mortality or morbidity rate. The increased prevalence of such resistant strains has narrowed down the list of available therapeutic options. Therefore, information regarding the prevalence of S. aureus infections in a health care setting and determining its current antibiotic resistance profile becomes crucial in selecting appropriate treatment regime. Therefore, the current study was done in the department of Microbiology to determine the prevalence of S. aureus infections and the antibiotic resistance pattern of S. aureus isolates from various clinical specimens at our tertiary care hospital in North India. Materials and Methods: A one year prospective study was carried out in the Department of Microbiology, at a tertiary care hospital in North India where non-duplicate strains of S. aureus isolated from various clinical specimens received in the Microbiology laboratory were studied. All S. aureus isolates were subjected to Antibiotic Susceptibility Testing using Kirby Bauer’s disk diffusion method on Mueller Hinton Agar plates in accordance to CLSI guidelines. The antibiotics tested included Penicillin (10U), Amoxicillin-clavulanic acid (20/10μg), Sulphamethoxazole-trimethoprim (1.25/23.75μg), Ciprofloxacin (5μg), Erythromycin (15μg), Clindamycin (2μg), Vancomycin (30μg), Teicoplanin (30μg) and Linezolid (30μg). Results: A total of 23,699 clinical specimens were processed in the laboratory while conducting this study, from which 1233 clinical isolates of S. aureus were identified and processed further. Among all clinical specimens, pyogenic samples (63.1%) yielded maximum number of S. aureus strains followed by blood samples (29.9%) and urine samples (4.8%). S. aureus infection was more evident in hospitalized 71.2% patients than in OPD patients 28.8%. Seasonal variation was also seen in isolation of S. aureus , with a higher percentage of isolates obtained during summer season than during winter season. On antibiotic susceptibility testing, 49.6% strains were Methicillin Resistant. Majority of the isolates were found resistant to Penicillin (92.1%), followed by Erythromycin (59%).
