All You Need To Know About Dermatology Laser Application Trends

 

INTRODUCTION

Over the past few decades, laser systems have been found extensive application in various clinical aspects of cosmetic surgery. From use in photocoagulation and vaporization of vascular malformations to removal of epithelial lesions, lasers have become an indispensable tool in surgery.

However, the thermal properties of laser treatment adversely affect the adjacent tissue, thus impacting wound healing and scar formation negatively. This problem has been addressed by the more selective and restrictive destruction of targeted tissue by the more recent laser systems like pulsed and Q-switched lasers matched to the target’s absorption characteristics.

These advances help in expanding the therapeutic spectrum of lasers in the field of cosmetic surgery and improvement in the quality of results achieved.

MODES OF OPERATION OF MEDICAL LASERS

Laser radiation used in dermatology work of the same basic principle but can be varied depending on the system used and the intended application keeping the three core variables in mind:

1. Wavelength

This can be tuned in dye lasers within a range by use of a single dye, the range can be broadened by exchanging the dye solution. Multiline regimen use is also possible with some lasers eg: Argon, Copper, etc.

2. Pulse Duration

The pulse duration is normally fixed in the Pulsed Q-switched lasers but the dose of radiation being delivered to a patient is dependent on other variables also like pulse energy, duration of exposure, and repetition rate.

3. Power

Mechanical and electrical shutters can be used to adjust the exposure time and CW systems help in the easy scaling of the power. Some systems also allow the beam to be scanned along the treated surface using acoustic and galvanometric or optic deflectors.

Three Dimensional Bone Printing

Bone restoration for patients is sometimes hard to be attained especially when there are infections or trauma, this had been a challenge to achieve in the past years. As there are complications to the conventional autografts or allografts, these challenges have led to the emerging of a new way to provide healthy bone tissues that are strong and patient-compatible. 

Three Dimensional Bone Printing technique is used for Patients requiring skeletal augmentation, for example, Facial asymmetry, Patients with facial trauma, Infections, Trauma, Congenital diseases.They are usually fit to be aided with three-dimensional bone printing procedure to restore normal human anatomy and function of the bone and the affected part.

Positron Emission Tomography Summary

Introduction to PET Scan

Positron Emission Tomography or PET is a method which is used to detect the cellular activity of a structure along with Magnetic Resonance Imaging (MRI) and Computerized Tomography (CT) it is used to create multidimensional color images of inside working of the human body. It shows not only what an organ looks like, but how it is functioning.

Working Principle of a PET Scanner 

PET scan uses a scanning device which detects the positron particles emitted from the target tissue or organ the radiotracers used in PET scans are made by attaching a radioactive atom to chemical substances that are used naturally by the particular organ or tissue during its metabolic process. For example, the radioactive element is applied to glucose which works as the primary source of energy for almost each and every organ of human body. The radionucleotide of glucose is called Fluorodeoxyglucose (FDG).

Innovations Treating Baby Jaundice

What is Jaundice?

Jaundice occurs when the body cannot discharge bilirubin, a substance that normally occurs when red blood cells are destroyed. The more the substance develops, the more yellowish is the skin of someone becomes.
In babies who have not yet developed the compounds that allow their bodies to eliminate bilirubin, jaundice is not simply normal, but can also cause permanent damage or even death. 

While first world nations have the innovation and the cash to treat babies, this treatment is often excessively expensive for those developing countries. The yellowness caused by the accumulation of the bile color bilirubin in the blood, influences around 60 percent of babies, and around 5 to 10 percent have jaundice sufficiently to require phototherapy.

The Heart Rate Observation System HeRO

HeRO Monitor

HeRO is an innovative checking structure giving another instrument to clinical evaluations of preemies that identify pulse anomalies in an infant youngster’s heart sooner than more prepared watching systems used as a piece of the NICU.

Research coordinated at a segment of the best neonatal serious care units a.k.a NICUs on the planet demonstrates that kids checked by the Heart Rate Observation System screen (HeRO) had a diminishing in mortality of 20 percent contrasted with those that were not on the screen.

Revolutionary Method Treating Diabetes

Diabetes Disorder

Diabetes mellitus is a chronic metabolic disorder characterized by high blood sugar levels, which result from defects in insulin secretion or action or both. Normally, blood glucose levels are tightly controlled by insulin, a hormone produced by the pancreas.[1] Diabetes can be either type 1 or type 2. 

Type 1 diabetes is also called as insulin dependent diabetes mellitus (IDDM) or juvenile onset diabetes mellitus. In type 1, the pancreas undergoes an autoimmune attack by the body itself and is rendered incapable of making insulin. Type 2 diabetes is referred as non-insulin dependent diabetes mellitus (NIDDM) or adult onset diabetes mellitus (AODM). 

In type 2 diabetes, the patient can still produce insulin but do so relatively inadequately for their body's needs.[2] Complications of diabetes may be acute or chronic. An acute complication of type 1 diabetes involves diabetic ketoacidosis (DKA) and type 2 involves hyperosmolar coma.

Chronic complications are related to blood vessels and are classified into Microvascular disease or Macrovascular disease. The microvascular disease involves eyes, kidneys, and nerves causing blindness, kidney failure, and nerve damage. Diabetes accelerates hardening and narrowing of the arteries (atherosclerosis), leading to strokes, coronary heart disease, and other large blood vessel diseases. These are referred to as macrovascular diseases.[3] Chronic low-grade inflammation, which is present in both type-1 and type-2 diabetes, contributes to the pathogenesis of insulin resistance. 

Proton Therapy Best Cancer Treatment

Introduction To Proton therapy 

Proton therapy is a radio beam therapy that is capable to deliver radiation through the skin with much-reduced pain compared to conventional radiation therapies. It is a technique which uses proton beam which is delivered to the tumor in a precise way where the surrounding tissue is left unharmed contrary to other procedures which damage the tissue to a smaller or greater extent.

A proton is a positively charged particle. At high energy, protons can destroy cancer cells.This technique may forever alter the nature of cancer treatment.

Proton Therapy Working procedure 

Protons are atoms that carry a positive charge, similar to X-Rays which contain photons and is used to treat benign as well as malignant tumors but the only difference here is that it delivers protons in a much more confined and precise way, After they enter the body, protons release most of their energy within the tumor region and, unlike photons, deliver only a minimal dose beyond the tumor boundaries the shape and size of the tumor is also not a big problem as the method divide the tumor into small pixels and the radiations are given on these small pixels.

How Single Photon Emission Computerized Tomography SPECT Works

SPECT Used in Cardiology Tests 

SPECT or Single Photon Emission Computerized Tomography also called SPET, in short, is an imaging technique using gamma rays and provides a three-dimensional information about the flow the blood to different organs of the body. It is usually presented as cross-sectional slices through the patient but can be freely reformatted or manipulated as required.

Advanced NICU Equipment

What is NICU

Infants needing basic therapeutic consideration are ordinarily admitted to the Neonatal Intensive Care Unit (NICU). These newborn children have a tendency to be preterm and have a low birth weight or potentially genuine medicinal conditions.

The blend of cutting-edge innovation and a prepared therapeutic group (counting neonatologists, medical caretakers, respiratory advisors, word related advisors, dieticians, and lactation experts) in the NICU adequately gives particular care to patients. Human services experts are frequently required to lead complex appraisals, execute profoundly escalated treatments, and make moment adjustments in light of the newborn child's reaction with a specific end goal to intercede before hazardous conditions arise.

Recent Advancements Within Bone Implants

Introduction

With increasing lifespans and improvement in the quality of life of elderly, joint replacements have started accounting for an increasing number of surgical orthopedic procedures.

In a landmark study done in the United States of America, it was concluded that one in every five adults suffers from arthritis.[1] The treatment for arthritis can be conservative or surgical depending on the severity of the case. However, this ratio puts into focus the magnitude of the problem and the dire need to come with more sustainable solutions for joint replacement therapy.

Evolution of biomaterials in Orthopedics

The last few decades have seen tremendous growth and improvement in the field of biomaterials with the evolution of 3 generations [2]. The first generation of bioinert materials, the second comprising of bioactive and biodegradable materials and the third consisting of materials with the ability to simulate the responses at a molecular level.
