Bone infection
This document discusses various types of bone infections including osteomyelitis. It describes acute suppurative osteomyelitis as a rapidly destructive inflammatory bone lesion caused by bacteria. Chronic suppurative osteomyelitis results from unresolved acute osteomyelitis and involves bone destruction. Diffuse sclerosing osteomyelitis is characterized by pain, inflammation and bone sclerosis or destruction. Focal sclerosing osteomyelitis occurs in response to localized dental infections. Proliferative periostitis involves periosteal bone formation in response to chronic infections. Alveolar osteitis or "dry socket" results from loss of a blood clot following tooth extraction.
Chronic osteomyelitis
Chronic osteomyelitis is a bone infection lasting over 6 weeks. It is characterized by recurrent inflammation, draining sinuses, and dead bone. Common causes are Staphylococcus aureus and other bacteria. Over time, the infection causes bone necrosis and formation of sequestra - dead bone pieces. Surgical treatment aims to thoroughly debride infected tissue, remove sequestra, and reconstruct the bone defect. Antibiotic therapy and soft tissue coverage are also important for treatment. Complications can include pathological fractures, deformity, and malignant transformation if not properly treated.
Chronic infections of jaw (oral infections)
1. Chronic infections or inflammatory diseases of the jaw bones can cause osteomyelitis, an inflammatory process that involves the bone marrow, cancellous bone, cortex, and periosteum.
2. Acute pyogenic osteomyelitis is usually caused by mixed bacterial infections spreading from odontogenic sources and presenting with pain, swelling, tooth mobility and tenderness, fever, and lymphadenopathy.
3. Chronic osteomyelitis can develop from an acute infection or be primary due to subvirulent microorganisms. It is characterized by periods of low-level pain and discharge, bone enlargement from new bone formation, and radiographic findings of radiolucencies overlaying radiopacities
Chronic Osteomyelitis
This document discusses chronic osteomyelitis, including its causes, pathology, presentations, examinations, investigations, differential diagnoses, and treatments. It can develop following acute osteomyelitis or be caused by tuberculosis or fungi. Pathology involves spread of pus within bone leading to bone death and cavities. Presentations include discharging sinuses and bone fragments. Investigations include x-rays showing bone changes and cultures of pus. Surgical treatments aim to remove dead bone and tissue. Complications include exacerbations, growth abnormalities, and fractures. It also discusses Garre's osteomyelitis and Brodie's abscess as specific types.
Chronic osteomyelitis2
This document discusses chronic osteomyelitis, a bone infection that lasts longer than 6 weeks. It describes the pathogenesis, presenting complaints, diagnosis, investigations, treatment, and complications of chronic osteomyelitis. There are three main types: secondary to acute osteomyelitis, Garre's osteomyelitis, and Brodie's abscess. Diagnosis involves clinical examination and radiological confirmation showing bone changes. Treatment primarily involves surgery to remove dead bone tissue followed by antibiotics. Complications can include exacerbations, bone deformities, and pathological fractures.
Osteomyelitis (Dentistry)
Osteomyelitis is an inflammation of the bone marrow that typically begins in the cancellous bone and spreads to cortical bone and periosteum. It is caused by a failure of microcirculation in cancellous bone and establishment of infection. While it can affect the maxilla, osteomyelitis more commonly impacts the mandible due to its blood supply originating from the inferior alveolar artery. Osteomyelitis of the mandible is usually preceded by odontogenic infections or mandible fractures and is more likely to occur in immunocompromised individuals. It is treated through surgical debridement, antibiotic administration, and stabilization of mandible fractures.
Osteomyelitis
Osteomyelitis is an inflammatory condition of bone tissue that is typically caused by bacterial infection. It begins in the bone marrow and can spread to involve the cortical bone and periosteum if left untreated. Key factors in its progression include impaired blood flow and immune function. It is classified as either suppurative (characterized by pus formation) or non-suppurative. Suppurative osteomyelitis may be acute or chronic, while non-suppurative types include chronic diffuse sclerosing osteomyelitis and Garre's sclerosing osteomyelitis. Treatment involves long-term antibiotic therapy along with surgical debridement to improve blood supply and support healing.

It concludes by differentiating osteomyelitis from related conditions like apical periodontitis and peri
Infective bone diseases
1) Osteomyelitis is a bone infection that can occur from bacteria spreading through the bloodstream, surrounding tissue, or directly exposing the bone through injury. Staphylococcal species are the most common pathogens in jaw osteomyelitis.
2) Chronic osteomyelitis is classified based on factors like recurrence, location, and presence of pus. It presents with pain, swelling, fever and bone changes on imaging like moth-eaten appearance and sequestration.
3) Treatment involves correct diagnosis through history, exams, imaging and biopsy. It may require surgical interventions like debridement and reconstruction as well as long-term antibiotics based on culture and sensitivity results.
Chronic Osteomyelitis
This document discusses chronic osteomyelitis, including its causes, symptoms, diagnosis, and treatment. It defines chronic osteomyelitis as a persistent bone infection caused by bacteria that form biofilms and evade the host immune system and antibiotics. Diagnosis involves imaging tests like X-ray, CT, MRI, and PET scans to identify dead bone fragments (sequestra) and determine the infection's extent. Treatment requires extensive surgical debridement to remove all infected and dead bone, along with long-term antibiotics and management of any underlying health issues predisposing to infection.
Osteomyelitis
Osteomyelitis is an infection of bone that has been described since ancient times. It is commonly caused by Staphylococcus aureus bacteria entering the bone hematogenously. Acute osteomyelitis typically affects the metaphysis of long bones in children. Chronic osteomyelitis results from untreated acute infection and is characterized by sequestered necrotic bone. Treatment involves antibiotics, drainage of pus, and surgical debridement or removal of infected bone.

Quittor IN EQUINES
Quittor describes a chronic, purulent inflammation of the collateral cartilage of the distal phalanx that often results in abscess formation and draining tracts near the coronary band. It is most commonly seen in the lateral cartilage of the forelimb and is usually caused by direct trauma that damages the blood supply to the cartilage. Diagnosis involves identifying recurrent swelling and draining tracts over the affected cartilage along with pain on hoof testing. While antibiotics and drainage may help control symptoms, surgical excision of the diseased cartilage provides the best treatment and prognosis when all infected tissue can be successfully removed.
Osteomyelitis
Osteomyelitis is inflammation of bone and bone marrow that is usually caused by bacterial infection. Acute hematogenous osteomyelitis is the most common type seen in India, typically affecting the distal femur or proximal tibia in children. Staphylococcus aureus is the main causative organism.

osteomylitis
Osteomyelitis is an infection of the bone that can be acute, chronic, or secondary to other infections. It is commonly caused by bacteria reaching the bone via the bloodstream and lodging in the metaphysis. Symptoms include pain, swelling, fever, and inflammation near the infected bone. Diagnosis involves blood tests showing infection and imaging studies like x-rays or bone scans. Treatment depends on illness duration but generally involves antibiotics, rest, splinting, and rehydration. Complications can include sepsis, chronic osteomyelitis, pyogenic arthritis, pathological fractures, and growth disturbances of the bone.
Chronic osteomyelitis
Chronic osteomyelitis is a persistent bone infection that can develop from acute osteomyelitis if the infection is not properly treated. It is characterized by the formation of dead bone (sequestra) surrounded by infected tissue. Treatment requires extensive surgical debridement to remove all infected and dead bone, followed by long-term antibiotics and procedures to fill dead space and promote healing. Complications can include continued infection, bone deformities, fractures and joint stiffness if not adequately addressed.
Osteomyelitis
Osteomyelitis is a severe bone infection caused by bacteria such as Staphylococcus aureus. The bacteria can enter the bone directly via injury or surgery or indirectly by spreading from another infected site. Symptoms include bone pain, swelling, and fever. Diagnosis involves medical history, physical exam, imaging tests, and bone biopsy to identify the bacteria. Treatment consists of antibiotics, immobilization, and sometimes surgery to remove infected bone. Nursing care focuses on pain management, immobilization, ensuring proper use of assistive devices, and educating patients on long-term treatment and self-care of osteomyelitis.

Osteomyelitis has been recognized since ancient times. It is an infection of bone that can be caused by bacteria, fungi, or other microbes entering through the bloodstream or directly through trauma. The most common type is acute hematogenous osteomyelitis, which typically affects children under 15 and presents as a rapidly destructive infection of the metaphysis of long bones. Staphylococcus aureus is the primary causative organism. Diagnosis involves blood tests, imaging like x-rays, ultrasound, bone scans or MRI, and tissue sampling. Treatment involves antibiotics along with surgical drainage and debridement if abscesses form or the infection fails to respond to antibiotics alone. Chronic osteomyelitis can develop if not properly
Chronic osteomyelitis
This document provides information on chronic osteomyelitis, including types, pathology, diagnosis, and treatment. It notes that chronic osteomyelitis is usually caused by delayed or inadequate treatment of acute osteomyelitis, which allows spread of infection and bone death. Key features include sequestra (dead bone), involucrum (dense bone overlying sequestra), sinus tracts, and irregular thickened bone visible on x-ray. Treatment involves surgery to remove dead bone and tissue along with antibiotics to eliminate infection. Complications can include exacerbations, growth abnormalities, fractures, or rarely malignant changes in long-standing cases.
BONE INFECTIONS.pptx
Osteomyelitis is an infection of bone that can be acute, subacute, or chronic depending on duration of symptoms. Acute osteomyelitis typically involves the metaphysis and is caused by bacteria like Staphylococcus aureus entering through breaks in skin or bloodstream. It causes inflammation, pus formation, and bone necrosis. Treatment involves antibiotics, surgery if abscess forms, and immobilization. Chronic osteomyelitis results from inadequate treatment of acute osteomyelitis and is characterized by bone destruction, cavities containing pus and bone fragments, and draining sinuses. Surgical debridement along with long-term antibiotics is usually required to treat chronic osteomyelitis.

2) It can be classified as acute (less than 2 weeks), subacute (2-6 weeks), or chronic (over 6 weeks) based on duration of symptoms. It can also be classified based on mechanism of infection such as exogenous (from outside trauma/surgery) or hematogenous (from another infectious site).
3) Staphylococcus aureus is the most common pathogen. Risk factors
Chronic maxillofacial infections
Chronic osteomyelitis is a bone infection that lasts for over 3 months. It can develop from acute infections becoming chronic due to highly resistant host factors, sub-virulent microbes, or less numerous microbes. Common causes are odontogenic infections, fractures, trauma, and hematogenous spread. Symptoms include pain, swelling and draining sinuses. Radiographically, there may be moth-eaten bone destruction, sequestra, and periosteal reaction over time. Treatment involves draining any abscesses, debriding necrotic tissue, identifying the pathogen, and long-term antibiotics.
OSTEOMYELITIS .pptx
This document provides an overview of the management of osteomyelitis. It begins by defining osteomyelitis as a suppurative bone infection caused by pyogenic organisms. It then covers the classification, etiology, pathogenesis, clinical presentation, diagnosis and treatment of both acute and chronic osteomyelitis. For acute osteomyelitis, the document highlights hematogenous spread as the main mechanism and emphasizes the importance of Staphylococcus aureus. It also outlines the pathophysiology, presentations, investigations and management including antibiotics and possible surgery. For chronic osteomyelitis, it discusses predisposing factors, classification systems, surgical debridement approaches and the goals of long-term treatment and limb salvage.
Myositis ossificans
This document discusses myositis ossificans, a condition where bone forms in muscle tissue or other soft tissues. It presents two main types - non-hereditary myositis ossificans, which usually occurs after trauma in adolescents and young adults, and myositis ossificans progressiva (also called fibrodysplasia ossificans progressiva or stone man syndrome), a rare genetic disorder where muscle and connective tissues are gradually replaced by bone. The document outlines the etiology, clinical features, diagnosis, histopathology, and treatment of both conditions. Surgical excision may be indicated if the condition causes intolerable pain, neurological compression, or limited range of motion.

Appraoch to autoimmune diseases.pptx
This is an approach to the basis of the common antibodies and the associated diseases, called autoimmune diseases.
Hydatidiform mole/ VESICULAR MOLE
- Hydatidiform mole is a benign tumor of the placenta that has malignant potential. It is more common in Asian women and those over 35.
- Complete moles are diploid and paternal in origin, while partial moles are triploid with both paternal and maternal chromosomes. Complete moles have no fetus while partial moles may have an abnormal fetus.
- Diagnosis is made through ultrasound showing cystic spaces and very high HCG levels. Management involves surgical evacuation followed by monitoring of HCG levels to detect malignant changes, as 20% of complete moles may develop into gestational trophoblastic neoplasia.
Mediators of inflammation
This document summarizes the key mediators involved in the inflammatory response. It discusses how chemical mediators called cytokines, chemokines, lipids like prostaglandins and leukotrienes, amines such as histamine, peptides, complement proteins, and nitric oxide are released from cells to coordinate and regulate inflammation. These mediators act through receptors on target cells to produce effects like increased vascular permeability, leukocyte migration, pain, and fever responses. The document also outlines the innate and acquired immune responses mediated by cells like phagocytes, natural killer cells, and antibodies.
Psoriasis
1. Psoriasis is a chronic, inflammatory skin disease characterized by well-defined, red, scaly plaques located over extensor surfaces and scalp.
2. It has a genetic predisposition and can be triggered by environmental factors such as trauma, infection, drugs, and stress.
3. Treatment involves topical therapies for mild disease and systemic therapies such as phototherapy, retinoids, methotrexate, and biological agents for more severe disease.
Hypertensive disorders in pregnancy
This document discusses hypertensive disorders in pregnancy, specifically pre-eclampsia. It defines pre-eclampsia and lists risk factors. Diagnosis involves high blood pressure and proteinuria. Classification ranges from mild to severe. Complications for the mother include seizures, stroke, liver or kidney damage. Management involves controlling blood pressure, preventing seizures with magnesium sulfate, and delivering the baby to resolve symptoms. Close monitoring of the mother and baby postpartum is important.
Parasitic infestations
This document summarizes various parasitic infestations and their clinical features. It discusses papular urticaria caused by sensitivity to insect antigens, scabies caused by the mite Sarcoptes scabiei, and different types of pediculosis caused by head lice, body lice, and crab lice. It also mentions other conditions like myiasis, pulicosis, tungiasis, cimicosis, blister beetle dermatitis, spider bites, demodicidosis, larva migrans, leishmaniasis, and lymphatic filariasis. For each condition, it provides details on the causative organism, clinical manifestations, distribution of lesions
Neurocutaneous disorders
This document summarizes several neurocutaneous disorders including neurofibromatosis type 1 and 2, tuberous sclerosis, and Sturge-Weber syndrome. It describes the neurological, cutaneous, and other system involvement for each disorder including common symptoms such as seizures, tumors, and skin lesions. Diagnostic criteria involving clinical findings are provided. The summary focuses on the key features and manifestations across body systems involved in these genetic neurocutaneous conditions.
Mullerian anomalies
This document discusses Mullerian anomalies/defects, which range from agenesis to duplication of the tubes, uterus, cervix and upper vagina. It covers the classification system used (AFS), incidence, etiology, genetics, embryogenesis, clinical features, diagnosis using imaging modalies like HSG, USG and MRI, and management of various anomalies like unicornuate uterus, didelphys, bicornuate, septate and arcuate uterus. Complications in reproduction from each anomaly and outcomes of treatments like metroplasty are also summarized. Diethylstilbestrol exposure related abnormalities are briefly discussed.
TOXOPLASMA GONDII AND STRONGYLOIDES
Toxoplasma gondii is a coccidian parasite transmitted through contact with infected cat feces or consumption of undercooked meat. It typically causes mild or asymptomatic infections but can cause severe brain and eye damage in fetuses, infants, and immunocompromised individuals. Strongyloides stercoralis is a nematode transmitted through skin contact with soil. It resides in the small intestine and can cause chronic diarrhea but also disseminate and cause potentially fatal infections in malnourished or immunosuppressed individuals. Both parasites are diagnosed through examination of infected tissues and confirmed with serological tests.
JVP - A SHORT REVIEW
The jugular venous pulse reflects right atrial pressure and is best examined in the right internal jugular vein. It normally displays three positive waves and two negative troughs related to atrial filling and emptying. Abnormalities can indicate conditions that elevate or lower right atrial pressure such as heart failure, tamponade, constriction. Specific wave changes suggest problems like tricuspid regurgitation or stenosis. The jugular venous pulse is a useful physical exam finding for cardiovascular assessment.
HEART MURMURS
Heart murmurs can be produced by turbulence in blood flow caused by abnormalities in heart valves or structures. A murmur is described by its timing in the cardiac cycle, location, intensity, quality, and radiation pattern.
A mid-systolic murmur is the most common murmur and can be caused by ventricular outflow obstructions like aortic stenosis, dilation of the aorta/pulmonary trunk, accelerated flow, or innocent murmurs from normal anatomical variations. Diastolic murmurs include early diastolic murmurs like aortic regurgitation and high-pressure pulmonary regurgitation, and mid-diastolic murmurs caused by stenosis of the mitral or tricuspid valves. Flow murmurs
Development of male and female reproductive system
The document describes the development of the male and female reproductive systems from the indifferent stage through sexual differentiation. It covers the development of the gonads (testes and ovaries), genital ducts, and external genitalia. Some key points include:
- The gonads initially develop as indifferent gonads before differentiating into testes or ovaries depending on the presence of the SRY gene on the Y chromosome.
- The genital ducts also initially develop in an indifferent stage before the mesonephric ducts develop into male structures like the epididymis and vas deferens, while the paramesonephric ducts develop into female structures like the uterus and fallopian tubes.
- External
Forceps delivery and vacuum extraction
Forceps delivery is an operative vaginal delivery procedure that uses obstetric forceps to assist in the extraction of the fetal head. Forceps have curved blades that fit around the fetal head to allow the operator to apply gentle traction. Forceps delivery is indicated when there are signs of fetal distress, prolonged second stage of labor, or maternal medical complications. Risks include laceration, hemorrhage, and injuries to the mother or baby. Proper technique and only performing the procedure when fully trained can help minimize risks.
Face Presentation
This document provides information on face presentation during childbirth. It defines face presentation as a cephalic presentation with the fetus in a complete extended attitude and the presenting part being the face. The two types of face presentation are primary (presenting before labor) and secondary (caused by extension during labor). The main positions are left and right mentoanterior and mentoposterior. Face presentation has a higher risk of complications compared to vertex presentation such as prolonged labor and increased need for operative delivery. The management involves allowing labor to progress for mentoanterior positions but cesarean section is usually needed for persistent mentoposterior.
E coli - Microbiology
E. coli is a normal flora in the gut but can cause several infections. It is the most common cause of urinary tract infections and can lead to different types of gastroenteritis depending on the strain. Some strains like EHEC O157:H7 can cause hemorrhagic colitis and potentially fatal hemolytic uremic syndrome in young children and the elderly. E. coli is also known to cause neonatal meningitis, wound infections after surgeries, and sepsis.
Blood supply of brain
The brain receives a high blood supply to meet its metabolic demands. Arterial blood reaches the brain through the internal carotid and vertebral arteries, forming the circle of Willis at the base of the brain before branching into smaller vessels. Venous blood drains from the brain into internal jugular veins. Disruption of blood flow to the brain through cerebrovascular accidents like stroke can cause rapid loss of consciousness or permanent brain damage. Cerebrospinal fluid produced by choroid plexuses circulates within ventricles and around the brain and spinal cord, carrying nutrients and waste products.
Comprehensive Overview of Medical Genetics
This document discusses genetic diseases and abnormal fetal development. It begins with definitions of genetic terms like genetic code, chromosomes, genes, and cell division. It then discusses abnormal fetal development including malformations, deformations, and disruptions caused by chromosomal abnormalities, genetic defects, and environmental factors. The document ends by covering perinatal pathology including birth defects and metabolic disorders.
Short Review of Thalassemias
This document provides information on thalassemia, a group of genetic disorders that result in reduced hemoglobin production and anemia. It discusses the different types of thalassemia including alpha and beta thalassemia. Alpha thalassemia is caused by genetic deletions of the alpha globin genes and has varying severity from silent carrier to Hemoglobin H Disease to Bart's Hydrops Fetalis Syndrome. Beta thalassemia results from mutations in the beta globin genes and includes forms ranging from silent carrier to beta thalassemia minor to intermedia to major. Laboratory tests outlined can help diagnose and differentiate types of thalassemia based on red blood cell morphology, hemoglobin analysis and iron studies.
Localising the lesion of the CNS
This document provides an overview of localizing neurological lesions, including definitions of key terms like the central nervous system and peripheral nervous system. It describes various motor and sensory pathways in the brain and spinal cord. Conditions covered include the corticospinal system, stroke syndromes, multiple sclerosis, cerebellar syndrome, and motor neuron disease. For each, the causes, signs, investigations, and management are summarized. Clinical case scenarios are also provided to help localize neurological lesions.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).
Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.Hemodialysis: Chapter 5, Dialyzers Overview - Dr.Gawad
