An inguinal hernia occurs when tissue, such as part of the intestine, protrudes through a weak spot in the abdominal muscles. The resulting bulge can be painful, especially when you cough, bend over or lift a heavy object. However, many hernias do not cause pain.
An inguinal hernia isn't necessarily dangerous. It doesn't improve on its own, however, and can lead to life-threatening complications. Your doctor is likely to recommend surgery to fix an inguinal hernia that's painful or enlarging. Inguinal hernia repair is a common surgical procedure.
Thoracentesis is a procedure in which a needle is inserted into the pleural space between the lungs and the chest wall. This procedure is done to remove excess fluid, known as a pleural effusion, from the pleural space to help you breathe easier. It may be done to determine the cause of your pleural effusion. Some conditions such as heart failure, lung infections, and tumors can cause pleural effusions.
In order to be able to look at tissues under a microscope, we need to first stain them with the right technique. Learn the main staining techniques used in histology today on our full video: https://khub.me/aux9w

As you probably know, histology is the study of the microscopic anatomy of cells and tissues. So we use staining methods to visualize and distinguish the different parts of cells and tissues since cells and their structures are usually transparent or colorless. The types of dyes used to color cells and their components can either be specific to particular structures, chemical groups or even molecules, and it can also be non-specific in which case most of the cell is stained in the same way.
When staining tissue samples, dyes that are used are either acidic or basic or a combination of the two. And why is that, you might be asking. Well, cellular structures such as nucleic acids or proteins have charged groups which are known as phosphate groups or carboxyl groups, just to name a couple. The dyes used in histology are colored organic compounds which also have a charge. Acidic dyes carry a negative charge and so they bind to positively-charged cell structures.
In the full version of this tutorial, we will cover some of the most common types of dyes used in histological staining of cells and their structures:
- basic dyes vs acidic dyes vs neutral dyes;
- hematoxylin and eosin;
- PAS - staining;
- Golgi method;
- Toluidine blue;
- Masson's trichrome;
- Osmium tetroxide;

The goal of surgical clipping is to isolate an aneurysm from the normal circulation without blocking off any small perforating arteries nearby. Under general anesthesia, an opening is made in the skull, called a craniotomy. The brain is gently retracted to locate the aneurysm. A small clip is placed across the base, or neck, of the aneurysm to block the normal blood flow from entering. The clip works like a tiny coil-spring clothespin, in which the blades of the clip remain tightly closed until pressure is applied to open the blades. Clips are made of titanium and remain on the artery permanently.

One of a series of films we produced to help patients, their families and carers learn more about some of the most common tests and procedures used to diagnose and treat blood diseases. Patients who have previously undergone these tests helped us to design the videos. Each film clearly explains what the procedure involves and addresses common issues and concerns including: Why your doctor recommended this procedure What you need to do to prepare What you can expect during the procedure What you need to do afterwards Not every patient will be referred for all of these tests and practice may differ slightly depending on where you are treated.
Ascites, the collection of fluid within the peritoneal space is caused due to a variety of causes including cirrhosis, cardiac causes, sinusoidal obstruction syndrome, tubercular peritonitis and pancreatitis, amongst others. Most commonly, the cause of ascots may be cirrhosis , which in turn, is most frequently causes by alcohol use, hepatitis C and non-alcoholic steatohepatitis. At the heart of the ascitic fluid analysis is the serum albumin ascitic gradient, the differential diagnosis of which has been discussed in detail in this presentation. Both low SAAG and high SAAG ascites have been dealt with in some depth, with a brief overview of the management of these conditions

Barrett's esophagus is a complication of chronic (long lasting) and usually severe gastrointestinal reflux disease (GERD), but occurs in only a small percentage of patients with GERD. Criteria are needed for screening patients with GERD for Barrett's esophagus. Until validated criteria are available, it seems reasonable to do screening endoscopies in GERD patients who cannot be taken off acid suppression therapy after two to three years. The diagnosis of Barrett's esophagus rests upon seeing (at endoscopy) a pink esophageal lining that extends a short distance (usually less than 2.5 inches) up the esophagus from the gastroesophageal junction and finding intestinal type cells (goblet cells) on biopsy of the lining. There is a small but definite increased risk of cancer of the esophagus (adenocarcinoma) in patients with Barrett's esophagus.
