The document provides guidance on descriptive terms used in dermatology to describe skin conditions, including location, color, shape and configuration of lesions. It discusses common skin diseases like atopic dermatitis, psoriasis, acne, and skin cancers. Emergency dermatology conditions are also covered such as angioedema, Stevens-Johnson syndrome, necrotizing fasciitis, and impetigo.
Erythema (from the Greek erythros, which means "redness") is skin or mucous membrane redness induced by hyperemia (increased blood flow) in superficial capillaries. It can occur as a result of any skin damage, infection, or inflammation. Nervous blushes are an example of erythema that is not related to any disease.
Cutaneous manifestations of internal malignancy and paraneoplastic syndromes gamal sultan
cutaneous manifestations are extremely valuable marker because they may well be the presenting manifestation of an underlying neoplasm.
Increased clinician awareness could prove beneficial for the patient by promoting earlier screening and diagnosis, as well as increased intervention measures, thereby significantly affecting the chances of survival and/or improving the quality of life of the patient

Eczema is not a single illness, but rather a name for a group of diseases connected due to similar symptoms. Skin rashes and autoimmune disorders can be described in this way.
Usually, dryness appears on hands, elbows, feet, knees, and the face. Rashes on contaminated areas start to itch and become even more inflamed when scratched. This illness is not infectious, but it is long-lasting.
Moreover, its intensity may change during the lifespan. Some children may overgrow the allergy while others remain highly vulnerable. The current disease can cause additional illnesses. Symptoms and intensity of skin inflammation are specific to each patient.
There is a variety of eczema types. Besides the most popular case, atopic dermatitis, there are about six other disease
variants, different in their methods of treatment and side effects.
All of them should be identified with the help of a specialist to ensure a specific approach for each case. Atopic dermatitis is the most widely spread type of disease. It is common among children and is often associated with asthma and hay fever.
Other types can be triggered by contact with an allergic substance, stress, improper moisturizing, insect bites, temperature shifts, pressure, and even genetic predisposition.
Each case is different in its look and side effects. The only common thing for them is that they are types of sore and dry skin that should not be scratched.
There is no single opinion regarding the cause of eczema. According to the latest research, various types of illnesses are caused by their different principles. Particularly, for the children of eczema-ill parents, the probability of developing the illness is much higher.

The lecture is prepared by Dr. Umme Kulsum Munmun, Assistant Professor for the 4th year students of Chandpur Medical College, Chandpur, Bangladesh. This was previously delivered to 4th year students of Cumilla Medical College. It contains a short description of the common diseases of skin and their pathology. Hopefully this will be helpful for all undergraduate medical students.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Editor's Notes
Primary genetic defect in skin barrier function (filaggrin).
Care of a patient with SJS/TEN requires:
Cessation of suspected causative drug(s) – the patient is less likely to die and complications are less if the culprit drug is stopped no later than the day that blisters/erosions appear
Hospital admission – preferably immediately to an intensive care and/or burns unit as this improves survival, reduces infection and shortens hospital stay
Nutritional and fluid replacement (crystalloid) by intravenous and nasogastric routes – reviewed and adjusted daily
Temperature maintenance – as body temperature regulation is impaired
Pain relief – as pain can be extreme
Sterile handling and reverse isolation procedures
Skin care:
topical antiseptics e.g. silver nitrate or chlorhexidine, (but not silver sulfadiazine as it is a sulfa drug)
dressings such as gauze with petrolatum or non-adherent nanocrystalline-containing gauze
biosynthetic skin substitutes can reduce pain
avoid using adhesive tapes
preferable not to remove the dead skin; leave the blister roof as a ‘biological dressing’
daily examination and skin culture to detect bacterial infection
Eye care:
daily assessment by ophthalmologist,
frequent eye drops/ointments (antiseptic, antibiotic, cortisone)
Mouth care:
mouthwashes
topical oral anaesthetic
Lung care:
may include aerosols, bronchial aspiration, physiotherapy
may require intubation and mechanical ventilation if trachea and bronchi are involved
Urinary catheter because of genital involvement and immobility
Psychiatric support for extreme anxiety and emotional lability
Physiotherapy to maintain joint movement and reduce risk of pneumonia
Regular assessment for infection including of skin, mucous membranes, catheter sites:
Staphylococcal infection is common; gram negative infection may also arise
appropriate antibiotic should be given if infection develops
prophylactic antibiotics are not recommended and may even increase the risk of sepsis
