Tuberculosis remains a major public health problem in India, with 40% of Indians harbouring the tuberculosis bacilli and over 2 million new cases reported in 2010 according to WHO. Gastrointestinal tuberculosis is not uncommon, with the ileocecal region being the most commonly involved site due to physiological factors that allow bacterial growth. Complications of gastrointestinal tuberculosis include obstruction, perforation, and malabsorption resulting from strictures, hyperplastic lesions, and inflammation.
This document discusses abdominal tuberculosis, providing details on types, pathogenesis, clinical features, diagnosis and management. Some key points:
1. Abdominal TB can involve the gastrointestinal tract, peritoneum and pancreatobiliary system. It is most commonly seen in the ileocecal region.
2. The incidence and severity of abdominal TB is increasing with the HIV epidemic, as extrapulmonary TB is more common in HIV patients.
3. Diagnosis involves imaging like CT scans and ultrasound, as well as ascitic fluid examination, microbiological tests and colonoscopy. Laparoscopy may also be used.
4. Management consists of anti-tuberculosis drugs for 6-18 months
This document discusses intestinal tuberculosis, which can involve any part of the gastrointestinal tract. Mycobacterium tuberculosis is usually the causative pathogen. It can reach the intestines through ingestion, hematogenous spread from a lung infection, or direct spread from adjacent organs. Common sites of infection include the ileocecal region. Symptoms vary depending on the location but often include abdominal pain, fever, weight loss, and changes in bowel habits. Investigations include blood tests, imaging modalities like ultrasound and CT, and acid-fast bacilli testing of biopsy specimens. Treatment involves a standard antibiotic regimen over 6 months along with nutrition support. Surgery may be needed for complications like obstruction, hemorrhage, or perforation
Abdominal tuberculosis is most commonly seen in the ileocecal region due to factors like stasis and abundant lymphoid tissue. It typically presents with abdominal pain and a mass in the right lower quadrant. Diagnosis involves imaging studies like ultrasound and CT scan showing thickened bowel walls and enlarged lymph nodes. Confirmation is by biopsy and PCR analysis. Treatment involves anti-tubercular drugs for 6-9 months along with surgery for complications like obstruction or hemorrhage. Prognosis is generally good with medical management but depends on early diagnosis and treatment.

Abdominal tuberculosis is a common form of extrapulmonary tuberculosis, accounting for 3-4% of all tuberculosis cases. It most commonly involves the ileocecal region of the small intestine. Clinical presentations can include constitutional symptoms like fever and weight loss as well as abdominal pain. Diagnosis is challenging and relies on clinical suspicion combined with imaging findings and histopathological evidence from biopsies. Common investigative tools include barium studies, ultrasound, and colonoscopy. Treatment involves a standard antitubercular therapy regimen.
Gastrointestinal stromal tumors (GISTs) are rare sarcomas that arise from the gastrointestinal tract. Most commonly found in the stomach, they represent 0.2% of gastrointestinal tumors. While often asymptomatic, they can present with bleeding, pain, or obstruction. Diagnosis involves imaging such as endoscopy or CT scan followed by biopsy showing immunohistochemistry positive for CD117 in 95% of cases. Treatment involves surgical resection with clear margins although adjuvant therapy with imatinib is often used for higher risk tumors. Outcomes have improved greatly in the past two decades with 5-year survival rates now over 50% with appropriate treatment.
Endoscopic submucosal dissection (ESD) is an endoscopic procedure that allows for en bloc resection of gastrointestinal lesions. Key aspects of ESD include injecting a lifting agent into the submucosa to elevate the lesion prior to marking the margins and performing a circumferential mucosal incision and submucosal dissection. ESD provides improved resection rates compared to endoscopic mucosal resection and allows for specimen retrieval intact for accurate histological assessment. While complications such as bleeding and perforation can occur, most are often managed endoscopically without need for surgery. ESD has become a standard treatment for early gastrointestinal cancers and pre-cancers when criteria for curative resection are met.
Abdominal tuberculosis is a common extrapulmonary manifestation of tuberculosis that most commonly involves the ileocaecal region of the small intestine. It can present with nonspecific constitutional symptoms like fever, weight loss, or abdominal pain. Diagnosis is challenging as findings can mimic other diseases like Crohn's disease, but imaging modalities like ultrasound, CT scan, and barium studies can reveal features suggestive of abdominal tuberculosis like enlarged lymph nodes, bowel wall thickening, strictures, and ascites. Blood tests are often nonspecific but may show elevated ESR or mild anemia. Sputum tests have low yield for diagnosis but help evaluate for concurrent pulmonary tuberculosis. Tissue sampling is often needed for confirmation.

Cellulitis vs necrotizing soft tissue infectionHaziq Mars
Cellulitis is an acute inflammatory skin infection caused by bacteria like streptococcus. It presents with pain, redness, swelling and warmth in the affected area. Necrotizing soft tissue infection (NSTI), sometimes called "flesh-eating disease", is a rapidly progressive infection of the deep soft tissues that causes tissue death. It is usually caused by streptococcus or staphylococcus and risk factors include immunosuppression. NSTI signs include poorly defined infection margins, edema beyond erythema, and skin gangrene or crepitus. Both require IV antibiotics but NSTI often needs early surgical debridement to remove dead tissue. With treatment, cellulitis has a good prognosis but untreated N
Skin and soft tissue infections (SSTIs) range from mild to life-threatening and involve microbial invasion of the skin layers and soft tissues. SSTIs are commonly caused by bacteria like Staphylococcus aureus or group A streptococci through direct trauma to the skin or hematogenous spread. SSTIs are classified and can present as impetigo, carbuncles, folliculitis, cellulitis, or erysipelas and are diagnosed clinically with management depending on the infection type and severity.

TB is transmitted through airborne droplets and has an incubation period of 4-12 weeks. Diagnosis involves tests like sputum smear microscopy, culture, tuberculin skin test, chest x-ray, and PCR. Standard treatment includes isoniazid, rifampin, ethambutol and pyrazinamide for 2 months, followed by isoniazid and rifampin for 4 more months. Drug resistance is a major problem, with MDR-TB resistant to isoniazid
This document provides information on tuberculosis (TB) and anti-tuberculosis drugs. It defines TB as a chronic bacterial infection caused by Mycobacterium tuberculosis, most commonly affecting the lungs. It describes the causative agents of TB and discusses why TB is a dreadful disease due to the protective cell wall of the bacteria. It then covers the pathogenesis, transmission, types, signs and symptoms, investigations and complications of TB. Finally, it provides details on first-line and second-line anti-tuberculosis drugs, including their mechanisms of action and pharmacokinetics.
Tuberculosis is caused by the bacterium Mycobacterium tuberculosis and usually affects the lungs. It remains a major global health problem, with around 10 million new cases and 1.5 million deaths per year worldwide according to the WHO. Tuberculosis flourishes in conditions of poverty, crowding and immunosuppression. Clinical manifestations vary depending on whether the infection is primary or secondary, and can include cough, fever, weight loss, or disseminated disease. Diagnosis involves smear, culture and radiography. Standard treatment is 6 months of multiple antitubercular drugs. Effectiveness of treatment is assessed by repeat smears and cultures after 2 and 5 months.
General outline of musculoskeletal tuberculosis by dr ashutoshAshutosh Kumar
The document discusses tuberculosis (TB), specifically skeletal/bone TB. It describes TB as a chronic infection caused by Mycobacterium tuberculosis that typically affects the lungs but can spread to other areas like bones and joints. Symptoms may include fever, weight loss, and bone/joint pain. Diagnosis involves tests like biopsy, smear, culture, and imaging scans. Treatment involves antibiotic therapy for 6-18 months depending on category. Surgery may be needed for complications or non-response to drugs. With proper treatment, TB is curable in most cases.
Typhoid intestinal perforation is a serious complication of typhoid fever caused by the bacterium Salmonella typhi. It occurs when the bacteria invade and damage the intestinal wall, usually in the terminal ileum, causing it to perforate. Risk factors include children and young adults in areas with poor sanitation and overcrowding. Symptoms include severe abdominal pain and tenderness. Diagnosis involves blood/stool cultures and imaging. Treatment requires correcting fluid/electrolyte deficits, antibiotics, and surgical closure of perforations with options like simple closure, resection, or temporary ileostomy.

How to Make a Field Mandatory in Odoo 17Celine George
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
