Edema is an excessive accumulation of fluid in the interstitial spaces or body cavities. There are several types and causes of edema. Cardiac edema is caused by congestive heart failure which increases venous pressure and hydrostatic pressure, pulling fluid from blood vessels into tissues. Renal edema can be caused by nephritic syndrome which causes salt and water retention, or nephrotic syndrome which decreases plasma protein levels. Hepatic edema manifests as ascites and is caused by portal hypertension or low plasma proteins in conditions like liver cirrhosis. Pulmonary edema can result from left heart failure or inflammation while cerebral edema includes cytotoxic edema from cell injury or vesogenic edema from blood brain barrier disruption.Edema & Haemorrhage by Girish Kumar K, has 30 slides with 5815 views.

Edema and haemorrhage were presented. Edema is the abnormal accumulation of fluid in tissues, and can be localized or generalized. It can be transudate or exudate depending on protein content. Haemorrhage is bleeding from blood vessels. Bleeding can be arterial, venous, or capillary. Arterial bleeding is bright red and emitted in a jet; venous bleeding is darker and steady; capillary bleeding is bright red and oozing. Bleeding can be primary, reactionary, or secondary depending on timing relative to injury or surgery. The causes, effects, and types of edema and haemorrhage were described.Gas gangrene by Praful SonnePatil, has 16 slides with 22872 views.

This document discusses gas gangrene, a rapidly spreading, potentially fatal infection caused by Clostridium bacteria. It enters the body through wounds or injuries contaminated with soil or feces and releases toxins that cause tissue death. Symptoms include severe pain, swelling, brownish fluid draining from wounds with a foul odor, skin discoloration, and palpable gas in muscles. Diagnosis involves examining wound fluid under a microscope. Treatment requires urgent debridement of dead tissue, antibiotics like penicillin, oxygen therapy, and possibly amputation of infected limbs to save the patient's life. Homeopathic remedies like Arsenicum, Crotalus, and Secale may provide additional support.Small vessel vasculitis by iyad07, has 52 slides with 4606 views.

Gas gangrene is caused by gas-producing bacteria such as Clostridium perfringens infecting crushed or puncture wounds in an anaerobic environment. It leads to localized muscle death and tissue necrosis. Symptoms include pain, fever, and swelling at the wound site with a foul odor. The infection can spread rapidly without prompt treatment which includes intravenous antibiotics, debridement of dead tissue, and possibly amputation of an affected limb. Untreated gas gangrene has high mortality rates due to sepsis and organ failure.Gangrene & amputation by Priyatham Kasaraneni, has 180 slides with 20632 views.

1) Gangrene is defined as macroscopic necrosis of tissues, and can be dry, wet, or gas gangrene. Dry gangrene is caused by reduced blood flow and progresses slowly, while wet gangrene develops rapidly due to blocked blood flow and favors bacterial growth. Gas gangrene is caused by Clostridium bacteria.
2) Amputation involves surgically removing a body extremity and is indicated for conditions like gangrene, trauma, tumors, and vascular insufficiency. The goals are to remove all infected tissue, achieve wound healing, and provide a stump that can accommodate a prosthesis.
3) Factors in determining the amputation level include the zone of injury, adequate tissue margins, circulationLymphangitis by Priya , has 13 slides with 3966 views.

Clinical features include characteristics of the site, size, shape, edges, floor, base, discharge, pain levels, and surrounding lymph nodes. Investigations may include hematological and biochemical tests, imaging, and biopsies. Management principles focus on determining the underlying cause, correcting comorbidities, adequate drainage and debridement, treating any infection, and using appropriate dressings to promote healing.Healing and repair by dinesh, has 40 slides with 38417 views.
Healing and repair dinesh Healing occurs through regeneration or scar formation depending on the cell and injury type. Wound healing follows two main pathways: primary intention for clean surgical wounds where edges are approximated, or secondary intention for wounds with separated edges and more tissue death. The process involves inflammation, granulation tissue formation, re-epithelialization, wound contraction and ECM deposition. Several local and systemic factors can delay healing including infection, poor blood supply, drugs, and nutritional deficiencies.

Diabetic foot + gangrene
Diabetic foot + gangrenegroup7usmkk Diabetic foot complications are a major source of morbidity and health care costs. They result from a complex interplay of ischemia, ulceration, infection, and Charcot's joint due to diabetes-related changes. Hyperglycemia leads to nonenzymatic glycosylation of proteins and tissues, formation of advanced glycosylation end products, and accelerated atherosclerosis. This causes peripheral vascular disease, neuropathy, and foot deformities which impair sensation and blood flow, making the feet susceptible to infection, ulceration, and gangrene. Charcot's joint is a destructive foot arthropathy caused by loss of sensation from diabetic neuropathy.
