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;

Shoulder Examination OSCE (Old Version) - Dr Gill
Shoulder Examination OSCE (Old Version) - Dr Gill DrPhil 221 Views • 2 years ago

Shoulder Clinical Examination - Medical School Clinical Skills - Dr Gill

Personally, I find the shoulder examination the most complex examination possibly as there are so many variations and special tests. Some of which overlap and some will relate specifically to a patients presentation.

Often in a medical school syllabus, only select special tests will be used. In this shoulder exam demonstration, we include the Hawkins-Kennedy Test looking for impingement. This is dovetailed with examination for bicipital tendonitis as this is another possible cause of impingement type symptoms.

This shoulder upper limb exam follows the standard "Look, Feel, Move" orthopaedic exam approach, and overall order as set out in MacLeods Clinical Examination

Watch further orthopaedic examinations for your OSCE revision:

Knee Examination

Hip Joint Clinical Examination

________

Please note that there is no ABSOLUTE way to perform a clinical examination. Different institutions and even clinicians will have differing degrees of variations - the aim is the effectively identify medically relevant signs.

However during OSCE assessments. Different medical schools, nursing colleges, and other health professional courses will have their own preferred approach to a clinical assessment - you should concentrate on THEIR marks schemes for your assessments.

The examination demonstrated here is derived from Macleods Clinical Examination - a recognized standard textbook for clinical skills.

How to Deliver a Baby in Breech Presentation ?
How to Deliver a Baby in Breech Presentation ? samer kareem 22,225 Views • 2 years ago

A breech birth occurs when a baby is born bottom first instead of head first. Around 3-5% of pregnant women at term (37–40 weeks pregnant) will have a breech baby. Most babies in the breech position are born by a caesarean section because it is seen as safer than being born vaginally.

Spontaneous Breech Delivery Childbirth
Spontaneous Breech Delivery Childbirth Mohamed 21,969 Views • 2 years ago

A breech birth is the birth of a baby from a breech presentation. In the breech presentation the baby enters the birth canal with the buttocks or feet first as opposed to the normal head first presentation.

There are either three or four main categories of breech births, depending upon the source:

* Frank breech - the baby's bottom comes first, and his or her legs are flexed at the hip and extended at the knees (with feet near the ears). 65-70% of breech babies are in the frank breech position.

* Complete breech - the baby's hips and knees are flexed so that the baby is sitting crosslegged, with feet beside the bottom.

* Footling breech - one or both feet come first, with the bottom at a higher position. This is rare at term but relatively common with premature fetuses.

* Kneeling breech - the baby is in a kneeling position, with one or both legs extended at the hips and flexed at the knees. This is extremely rare, and is excluded from many classifications.

As in labour with a baby in a normal head-down position, uterine contractions typically occur at regular intervals and gradually cause the cervix to become thinner and to open. In the more common breech presentations, the baby’s bottom (rather than feet or knees) is what is first to descend through the maternal pelvis and emerge from the vagina.

At the beginning of labour, the baby is generally in an oblique position, facing either the right or left side of the mother's back. As the baby's bottom is the same size in the term baby as the baby's head. Descent is thus as for the presenting fetal head and delay in descent is a cardinal sign of possible problems with the delivery of the head.

In order to begin the birth, internal rotation needs to occur. This happens when the mother's pelvic floor muscles cause the baby to turn so that it can be born with one hip directly in front of the other. At this point the baby is facing one of the mother's inner thighs. Then, the shoulders follow the same path as the hips did. At this time the baby usually turns to face the mother's back. Next occurs external rotation, which is when the shoulders emerge as the baby’s head enters the maternal pelvis. The combination of maternal muscle tone and uterine contractions cause the baby’s head to flex, chin to chest. Then the back of the baby's head emerges and finally the face.

Due to the increased pressure during labour and birth, it is normal for the baby's leading hip to be bruised and genitalia to be swollen. Babies who assumed the frank breech position in utero may continue to hold their legs in this position for some days after birth.

A tissue is a group of cells that has a similar structure and acts together to perform one or more specific functions. In this tutorial, we will introduce you to the 4 main types of tissues in the human body: epithelial tissue, connective tissue, muscle tissue and nervous tissue. Epithelial tissue creates protective boundaries and is involved in the diffusion of ions and molecules, whereas connective tissue underlies and supports other tissue types.

Muscle tissue contracts to initiate movement in the body and nervous tissue transmits and integrates information through the central and peripheral nervous systems.

In this video tutorial we will take a closer look at the histology of the main cells and tissues under the microscope.

Why is laparoscopic surgery done?
Why is laparoscopic surgery done? Surgeon 41 Views • 2 years ago

Laparoscopic surgery is minimally-invasive (keyhole) surgery and it is performed through very small incisions, using a camera to guide the surgeon during the procedure. Miss Sarah Mills, a top colorectal surgeon, explains why laparoscopic surgery is performed over alternative methods.

Fetal Surgery for CCAM and the EXIT Procedure (6 of 10)
Fetal Surgery for CCAM and the EXIT Procedure (6 of 10) Surgeon 71 Views • 2 years ago

If a fetal lung lesion is causing heart failure, fetal surgery may be performed to remove the CCAM before birth. http://fetalsurgery.chop.edu

N. Scott Adzick, MD, Mark Johnson, MD, and Holly Hedrick, MD, experts from the Center for Fetal Diagnosis and Treatment at Children’s Hospital of Philadelphia, explain when fetal intervention for CCAM is recommended, the various approaches that may be used to treat the most complex fetal lung lesions before birth, and how these procedures are performed.

One concern with fetal lung lesions is that they take up space in the chest. If the lung mass grows and pushes the heart and other organs out of place, it can lead to complications such as fetal hydrops (heart failure in the fetus). If this happens, a fetal surgery procedure may be performed to remove the CCAM before birth.
In other cases, an EXIT procedure may be performed to partially deliver the baby, so the team can remove the mass before the baby is fully delivered.

In this video series, parents, nurses and doctors from Children’s Hospital of Philadelphia’s Center for Fetal Diagnosis and Treatment talk about the different types of fetal lung lesions like congenital cystic adenomatoid malformation (CCAM) and bronchopulmonary sequestration (BPS), the importance of accurate diagnosis and monitoring, and the most advanced treatment options currently available. They also discuss follow-up care and long-term outcomes for babies diagnosed with fetal lung lesions.
