Oral Lichen Planus is a common chronic inflammatory disease that affects the oral mucosa. It is characterized by T-cell mediated apoptosis of epithelial cells that leads to inflammation. The cause is unknown but believed to be autoimmune in nature. It presents as white reticulated lesions that can be reticular, papular, plaque-like, atrophic, erosive, bullous or ulcerative. Histopathology shows saw-tooth rete pegs and Civatte bodies. Direct immunofluorescence demonstrates a fibrin band in the basement membrane. The erosive form has a risk of malignant transformation.

Ludwig's angina is a severe bacterial infection that involves the submandibular, sublingual, and submental spaces of the neck. It causes swelling in these areas bilaterally and can potentially lead to airway obstruction. The infection is usually caused by both aerobic and anaerobic bacteria spreading from an odontogenic source such as a dental abscess. Treatment involves aggressive antibiotic therapy, incision and drainage of the swollen areas, and airway management to prevent respiratory distress. Without proper treatment, Ludwig's angina can cause complications such as sepsis, mediastinitis, or even death from asphyxiation within 12 to 24 hours.Osteomyelitis of jaw

Pleomorphic adenoma is the most common benign tumor of the parotid gland. It consists of both epithelial cells and spindle-shaped mesenchymal cells within an abundant mucoid matrix. On pathology, it displays well-differentiated epithelial cells and spindle/stellate cells in a pleomorphic stroma with mucoid material. The tumor presents as a slow-growing, painless swelling of the parotid gland and is diagnosed by FNAC. The treatment is complete surgical excision via superficial parotidectomy while preserving the facial nerve. Recurrence is possible if there are pseudopods left behind or inadequate margins. Malignant transformation may occur in long-standing tumors.Cervical mases DDx and Radio-imaging by B.H.A.A Malik

Specific conditions are discussed like parotitis, submandibular gland stones, and salivary gland tumors. Parotitis includes mumps infection which causes inflammation of the parotid glands. Submandibular gland stones form in the salivary ducts. Benign tumors are most common, with pleomorphic adenoma being the most frequent. Malignant tumors can also occur, such as mucoepidermoid carcinoma and adenoid cystic carcinoma.Rectal diseases

This document discusses various rectal diseases including prolapse, proctitis, polyps, benign lesions, and carcinoma. Rectal prolapse is classified as mucosal or full-thickness and can be caused by straining, weak pelvic floor muscles, or trauma from childbirth. Treatment depends on the type but may include injections, banding, or surgery. Proctitis is inflammation that can be caused by infection, radiation, or inflammatory bowel disease. Polyps are growths that can be removed endoscopically if small or via surgery if large. Benign lesions include endometriosis, hemangiomas, and neuroendocrine tumors. Rectal carcinoma is often treated with surgery such as anterior resection or6. diseases of the external ear

Diseases of the external ear can be congenital, traumatic, inflammatory, or neoplastic in nature. Common inflammatory conditions include otitis externa, perichondritis, and keratosis obturans. Otitis externa may be localized like furunculosis or diffuse. Malignant otitis externa is a severe infection that can spread to the skull base. Preauricular sinus and hematoma of the pinna are examples of traumatic external ear diseases. Treatment involves cleaning, topical or oral antibiotics, incision and drainage of abscesses, and sometimes surgery. Recurrence is possible with some conditions.Diseases of the external ear

Otitis externaAhmed Almumtin

Otitis externa refers to infections of the external ear canal. It can be acute or chronic. Acute otitis externa is commonly known as swimmer's ear and is caused by bacterial or fungal infections due to water exposure. Chronic otitis externa is defined as lasting over 4 weeks and is often due to bacterial, fungal, or dermatological causes. Necrotizing external otitis is a potentially lethal infection seen in immunocompromised patients like diabetics. Treatment involves topical or oral antibiotics, cleaning of the ear canal, and surgery in severe cases. Proper diagnosis depends on history, exam, and sometimes imaging or labs.Hypopharyngeal carcinoma

This document provides an overview of hypopharyngeal carcinoma, including its anatomy, epidemiology, etiology, presentation, investigations, treatment options, and complications. Hypopharyngeal carcinoma most commonly arises in the piriform fossa and affects males over age 60, with risk factors including alcohol, smoking, and irradiation. Presenting symptoms include dysphagia, sore throat, and neck mass. Treatment depends on staging and may include surgical excision, chemoradiotherapy, or radiotherapy alone. Complications can include bleeding, tracheal damage, leakage, and swallowing difficulties.Surgical options for different Pleural Diseases

For pleural effusion, it describes the types (hydrothorax, haemothorax, pyothorax), causes, signs and symptoms, investigations including thoracentesis, and treatments including drainage, pleurodesis, and surgery. For empyema, it covers definition, causes, pathogenesis, complications, investigations and criteria for diagnosis, and treatments including antibiotics, drainage, decortication, and thoracoplasty.

MeningococciArun Geetha Viswanathan
油
Meningococci are a type of bacteria that cause serious infections. The most common infection is meningitis, which is an inflammation of the thin tissue that surrounds the brain and spinal cord. Meningococci can also cause other problems, including a serious bloodstream infection called sepsis. In its early stages, you may have flu-like symptoms and a stiff neck. But the disease can progress quickly and can be fatal. Early diagnosis and treatment are extremely important. Lab tests on your blood and cerebrospinal fluid can tell if you have it. Treatment is with antibiotics. Since the infection spreads from person to person, family members may also need to be treated.
A vaccine can prevent meningococcal infections.Recently uploaded (20)

Flag screening is a crucial part of physiotherapy assessment that helps in identifying medical, psychological, occupational, and social barriers to recovery. Recognizing these flags ensures that physiotherapists make informed decisions, provide holistic care, and refer patients appropriately when necessary. By integrating flag screening into practice, physiotherapists can optimize patient outcomes and prevent chronicity of conditions.Presentaci坦 "Projecte Benestar". MWC 2025
