Amoebiasis by bhanu chalise, iom maharajgunj
Amebiasis is caused by the protozoan Entamoeba histolytica and is a major public health problem globally. It is commonly found in developing tropical and subtropical countries where poverty, poor sanitation, and malnutrition are prevalent risk factors. E. histolytica infection may be asymptomatic or may cause intestinal disease ranging from mild diarrhea to severe colitis or extraintestinal infections such as amoebic liver abscess. Diagnosis involves identification of trophozoites or cysts in stool samples or detection of antibodies or antigens in blood tests. Treatment involves luminal agents such as metronidazole to eliminate active infections and tissue amoebicides such as diloxanide furoate to clear cyst
Amoebiasis
Amoebiasis, also known amoebic dysentery, is an infection caused by any of the amobae of the Entamoeba group. Symptoms are most common during infection by Entamoeba histolytica. Amoebiasis can be present with no, mild, or severe symptoms. Symptoms may include abdominal pain, diarrhea, or bloody diarrhea.

Amebiasis in children
This document provides information on Entamoeba histolytica, a pathogenic protozoan parasite. It outlines the etiology, epidemiology, pathogenesis, clinical manifestations, diagnosis, treatment, and complications of E. histolytica infection. Key points include:
- E. histolytica infects up to 10% of the world's population and is a major cause of parasitic death. It typically causes asymptomatic colonization but can lead to amebic colitis or liver abscess.
- Infection occurs through ingestion of cysts in contaminated food/water. Cysts excyst in the intestine and trophozoites may invade the colonic mucosa.
- Diagnosis involves antigen detection in stool
Amoebiasis pathogenesis and pathology
This document summarizes Entamoeba histolytica, the causative agent of amoebiasis. It causes infection via fecal-oral transmission or oral sex. Virulence is determined by strain characteristics and host immunity. The parasite infects the intestine, where it may cause lesions and ulceration. It can spread to other organs like the liver to cause abscesses. Liver abscesses typically appear as solitary masses in the right lobe and contain anchovy sauce-like pus. The parasite may also infect the brain, skin or urogenital tract in rare cases.
Entamoeba histolytica
This document discusses Entamoeba histolytica and amebiasis. It notes that E. histolytica infections are usually asymptomatic in 90% of cases caused by non-pathogenic strains, while 10% of cases caused by pathogenic strains can result in symptomatic infection. The route of infection is oral through ingestion of contaminated food or water containing cysts. Clinical features of amebiasis include amebic colitis, fulminating enterocolitis, ameboma, and amebic liver abscess. Amebic colitis presents with symptoms like diarrhea with blood or mucus, or both, and weight loss. Complications can include anemias or megacolon.

ENTAMOEBA HISTOLYTICA
This document provides information on Entamoeba histolytica, the protozoan parasite that causes amoebiasis in humans. It discusses the organism's classification, morphology, life cycle, pathogenesis, diagnosis, treatment and prevention. Key points include:
- E. histolytica lives in the large intestine and can cause intestinal amoebiasis or spread to the liver to cause amoebic liver abscess.
- It has three stages - trophozoite, pre-cystic and cystic. Cysts are the infective form passed in feces.
- Infection occurs by ingesting cysts which excyst in the intestine. Trophozoites multiply
Amoebiasis clinical features
Intestinal amoebiasis presents with abdominal pain and tenderness, diarrhea, and painful bowel movements over 1-several weeks. Mild cases show mucus diarrhea without blood, while severe cases have bloody, bulky stools with fever and cramps. Physical exam may reveal hepatomegaly, localized tenderness, rales, jaundice, or epigastric tenderness. Extra-intestinal amoebiasis can cause liver abscess, skin lesions, or infection of other organs.
Amebiasis
Amebiasis is caused by the protozoan Entamoeba histolytica. It commonly causes asymptomatic intestinal infection but can also cause intestinal disease ranging from dysentery to liver abscesses. The parasite exists in two forms - a motile trophozoite form and a cyst form. Infection occurs through ingestion of cysts in contaminated food or water. Most infections are asymptomatic, but 10% can cause intestinal or extraintestinal disease. Diagnosis involves stool examination and serology. Treatment involves luminal agents for intestinal infection and metronidazole or tinidazole for invasive disease. Surgery may be needed for complications like perforation or toxic megacolon.
Intestinal amoebae

Urinary tract infection or UTI is an infection that affect your urinary system including the urethra,bladder,ureters and the kidneys.Most commonly occur in females compared to men due to the anatomical variation. At least one episode of urinary tract infection can experienced by each individual during their entire lifetime and the risk of developing reinfection is higher in these people compared to those who do not experience initial infection before.After menopause, patient with indwelling catheters are also have high risk of getting UTI. Variety of pathogenic organisms mainly E.coli plays a vital role in UTI. Proper management helps to eliminate infection and protect your urinary system from the development of complications such as kidney failure. Prophylactic antibiotic therapy also helps to prevent from the recurrence of infection.

Urinary Tract I nfection.pptx
This document discusses urinary tract infections (UTIs) in children. It notes that UTIs are commonly caused by Escherichia coli entering the urinary tract via the fecal-perineal-urethral route. Left untreated, upper UTIs can lead to renal scarring, hypertension, and end-stage renal disease. The gold standard for diagnosing UTIs is a urine culture with a threshold of 105 CFU/ml for a positive result. Treatment involves antibiotics chosen based on culture and sensitivity results, with recurrent infections requiring evaluation and possibly long-term prophylaxis to prevent renal damage.
Isk dwi lestari [compatibility mode]
Urinary tract infections (UTIs) are among the most common infections encountered by doctors. They can affect people of all ages and have a wide range of clinical manifestations, from asymptomatic to severe systemic symptoms. The urinary tract is normally sterile, and any bacterial growth in the urine constitutes a UTI regardless of bacterial count. UTIs are commonly caused by bacteria like E. coli entering the urinary tract and multiplying. Treatment depends on whether the infection is uncomplicated or complicated by anatomical or functional factors. Empiric broad-spectrum therapy is started and later adjusted based on culture and sensitivity results.
Uti
Urinary tract infections are caused by bacterial invasion of the urinary tract. E. coli is the most common cause, accounting for 85% of community-acquired and 50% of hospital-acquired UTIs. Women are more susceptible than men due to anatomical differences. Symptoms include dysuria, urinary frequency, and abdominal pain. Diagnosis involves urine dipstick, microscopy to check for white blood cells, and culture to confirm bacteria over 102 CFU/mL. Treatment depends on severity and location of infection, with antibiotics like ciprofloxacin as first line options. Prevention focuses on hygiene and prompt treatment of infections.

The document discusses urinary tract infections (UTIs). It begins by defining a UTI as an infection caused by microbes like bacteria, fungi or viruses in the urinary tract. The urinary tract includes the kidneys, ureters, bladder and urethra. UTIs are commonly caused by Escherichia coli bacteria entering through the urethra. Risk factors include female anatomy, birth control use, catheter use, and suppressed immunity. Symptoms depend on the infected area and range from increased urination to fever. Diagnosis involves urine culture and imaging tests. Treatment involves drinking fluids, cranberry juice, antibiotics, and preventing recurrence.

Systemic corticosteroids are synthetic derivatives of cortisol that can be taken orally or via injection. They are used to treat various autoimmune and inflammatory conditions. Common side effects include increased risk of infection, skin thinning, acne, osteoporosis, diabetes, and psychiatric issues. Risks are higher with longer term or high dose use. Monitoring of blood pressure, weight, and blood sugar is recommended during treatment. Measures like calcium/vitamin D supplementation and bone density scans can help prevent side effects like osteoporosis. Some conditions like active tuberculosis or severe psychiatric disease are contraindications for steroid use due to risk of worsening.
Oncology section a
Carcinogenesis is the process by which normal cells are transformed into cancer cells due to mutations in DNA that disrupt the orderly processes regulating cell proliferation and death. This results in uncontrolled cell division. A series of mutations in proto-oncogenes that promote cell growth and tumor suppressor genes that discourage cell growth are required before a normal cell transforms into a cancer cell. The ras oncogene and p53 tumor suppressor gene are examples that are commonly mutated in cancer. Grading of cancers provides information on prognosis and treatment by assessing how differentiated the cancer cells are from normal cells.
