Roadmap on computational methods in optical imaging and holography [invited].

Unlabelled: Computational methods have been established as cornerstones in optical imaging and holography in recent years. Every year, the dependence of optical imaging and holography on computational methods is increasing significantly to the extent that optical methods and components are being completely and efficiently replaced with computational methods at low cost. This roadmap reviews the current scenario in four major areas namely incoherent digital holography, quantitative phase imaging, imaging through scattering layers, and super-resolution imaging.

Early and Long-Term Morbidity and Mortality Following Pancreaticoduodenectomy for Periampullary Tumors in Elderly Patients.

Aim: The growing elderly population is facing an increasing risk of cancers, consequently raising the pancreatic cancer surgery rate. This study aimed to determine whether advanced age is a risk factor for morbidity and mortality following pancreaticoduodenectomy (PD) for periampullary tumors.

Materials And Methods: The present study included 90 patients who underwent PD for periampullary tumors.

The effect of simultaneous administration of occipital nerve block and cervical myofascial trigger point injection (MTrPI) on headache parameters in chronic migraine patients.

Background And Aim: Peripheral myofascial mechanisms have been identified as contributors to migraine pathophysiology. The specific comorbid relationship between migraine and cervical trigger points may exacerbate the occurrence and severity of migraine attacks. Trigger point injections (TPIs) are frequently employed to address headaches and alleviate migraine symptoms.
