In the modern era, endoscopic retrograde cholangiopancreatography (ERCP) and therapeutic endoscopic ultrasound (EUS) are increasingly being performed in day-care settings. The safety of these procedures in elderly admitted patients has been established in previous studies, but evidence for the safety of day-care ERCP/therapeutic EUS is limited. We retrospectively analyzed the outcomes of day-care ERCP/EUS in patients more than 80 years of age. All procedures were done under total intravenous anesthesia (ketamine- and propofol-based) and the intra-procedural and immediate postprocedural complications (within 6 hours) were noted. Thirty patients (24 male and 6 female) were enrolled. The most common indication for the procedure was choledocholithiasis (46.6%), followed by malignant stenosis (30.0%) and benign strictures (20.0%). One patient had transient desaturation during the procedure and two patients had hypotension. The dreaded complications of bleeding, perforation, or pancreatitis did not occur in any patients, and none required admission. In conclusion, day-care therapeutic ERCP/EUS is safe and cost-effective in the oldest old patients.

Fusion of Medical Images using a Wavelet Methodology: A Survey
Satya Prakash Yadav,Sachin Yadav 대한전자공학회 2019 IEIE Transactions on Smart Processing & Computing Vol.8 No.4
Image compression or fusion is the concept of identifying in-depth parameters of disease variables, and requires output images that preserve all the viable and prominent information that is gathered from source images without any further introduction of artifacts or unnecessary distortions. Measurement of images for prospective evaluation and image fusion depends on various performance measures, such as structure similarity index, standard deviation, edge detection, correlation coefficient and high pass correlation, average gradient, root-mean-square error, peak signal-to-noise ratio, entropy, etc. This review discusses various medical image fusion modalities focused on Principal Component Analysis, Independent Component Analysis, and wavelet transform. An introduction to the usefulness of such modalities is presented, suggesting safe hybrid modality combinations that could greatly enhance the image fusion process. Novel trends in medical image fusion techniques to achieve a perfectly desired, quality image, the future prospects of an ideal technique for medical imaging, and recognition of diseases are covered.
CYP1A1 Gene Polymorphisms: Modulator of Genetic Damage in Coal-Tar Workers
Giri, Shiv Kumar,Yadav, Anita,Kumar, Anil,Dev, Kapil,Gulati, Sachin,Gupta, Ranjan,Aggarwal, Neeraj,Gautam, Sanjeev Kumar Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.7
Aim: It is well known that polycyclic aromatic hydrocarbons (PAHs) such as benzo (a) pyrene have carcinogenic properties and may cause many types of cancers in human populations. Genetic susceptibility might be due to variation in genes encoding for carcinogen metabolizing enzymes, such as cytochrome P-450 (CYP450). Our study aimed to investigate the effect of genetic polymorphisms of CYP1A1 (m1 and m2) on genetic damage in 115 coal-tar workers exposed to PAHs at their work place. Methods: Genetic polymorphisms of CYP1A1 were determined by the PCR-RFLP method. Comet and buccal micronucleus assays were used to evaluate genetic damage among 115 coal tar workers and 105 control subjects. Results: Both CYP1A1 m1 and CYP1A1 m2 heterozygous and homozygous (wt/mt+mt/mt) variants individually as well as synergistically showed significant association (P<0.05) with genetic damage as measured by tail moment (TM) and buccal micronuclei (BMN) frequencies in control and exposed subjects. Conclusion: In our study we found significant association of CYP1A1 m1 and m2 heterozygous (wt/mt)+homozygous (mt/mt) variants with genetic damage suggesting that these polymorphisms may modulate the effects of PAH exposure in occupational settings.
