• Intermittent Fever

  Abstract A 16-year-old Caucasian girl of Albanian origin was admitted to the hospital complaining of intermittent fever (38 degrees C) for a week, nausea, vomiting, and abnormal laboratory findings (elevated serum aminotransferases levels AST/ALT 77/40 [ncbi.nlm.nih.gov]

• Nausea

  Both assemblages caused similar illness, but assemblage AII was significantly more frequently associated with abdominal pain, nausea and vomiting. [ncbi.nlm.nih.gov]

  Symptoms include diarrhea, abdominal pain, anorexia, bloating, nausea, and vomiting. [sharinginhealth.ca]

  Diarrhea is the major symptom of the disease but the clinical manifestations vary; from non-symptomatic infections to severe diarrhea, abdominal cramps, bloating and flatulence often accompanied by nausea and weight loss. [certest.es]

• Abdominal Pain

  Both assemblages caused similar illness, but assemblage AII was significantly more frequently associated with abdominal pain, nausea and vomiting. [ncbi.nlm.nih.gov]

  Symptoms include diarrhea, abdominal pain, anorexia, bloating, nausea, and vomiting. [sharinginhealth.ca]

• Failure to Thrive

  In chronic giardiasis, symptoms are recurrent and can lead to failure to thrive, malabsorption and debilitation. return to top Diagnosis Giardiasis is diagnosed by the identification of cysts or trophozoites in the feces, using direct mounts as well as [sharinginhealth.ca]

  It can also be misdiagnosed as celiac disease or failure to thrive syndrome. Symptoms can last for two to three weeks, with gradual improvement. [innvista.com]

  Symptoms are usually chronic and intermittent, characterized by diarrhea without blood or mucus, flatulence, abdominal pain, belching, malabsorption, and failure to thrive or lack of weight gain. [aafp.org]

  In children there may be failure to thrive as a result of the prolonged infection. The epidemiology of Giardiasis has been strongly associated with overseas travelers and wilderness hikers. [dlslab.com]

  Possible complications Failure to thrive (children) or malabsorption. [patient.info]

• Odynophagia

  We describe the case of a 51-year-old woman presenting with dysphagia, odynophagia, long-lasting low-grade fever, and malabsorption syndrome who underwent an upper gastrointestinal endoscopy showing esophageal candidiasis. [ncbi.nlm.nih.gov]

• Melena

  He reported foamy stools but no blood or melena and had crampy epigastric pain. He denied usage of antibiotics. [ncbi.nlm.nih.gov]

• Liver Mass

  Imaging studies revealed a liver mass and a pancreatic head mass. [ncbi.nlm.nih.gov]

• Responsiveness Decreasing

  The IgG/M response decreased more gradually but remained significantly higher than presumed unexposed controls at all time points, except for anti-VSP3 at 12 months. [ncbi.nlm.nih.gov]

Relying on disease-specific surveillance systems for detection of outbreaks is not sufficient when the pathogen is difficult to diagnose, or when it is non-endemic in the area and therefore not part of the routine diagnostic workup. [doi.org]

• Tropheryma Whipplei

  Abstract Whipple's disease is a rare systemic condition resulting from a chronic infection by Tropheryma whipplei. Clinical presentation can be widely heterogeneous, often leading to delayed diagnosis and treatment. [ncbi.nlm.nih.gov]

What Is the Prognosis for Giardiasis? Cure rates are high with appropriate medication in an otherwise healthy person. [emedicinehealth.com]

Abstract Giardia lamblia is the etiologic agent of giardiasis, a water-borne infection that is prevalent throughout the world. The need for new therapeutics for the treatment of giardiasis is of paramount importance. [ncbi.nlm.nih.gov]

The English and the French, especially, believed it to be the etiologic agent in many cases of "trench diarrhea." [jamanetwork.com]

Etiology Pathogen : Giardia lamblia ; (also known as Giardia intestinalis or duodenalis ), a protozoan Transmission Waterborne: from drinking of recreational water (e.g., lakes, rivers, ponds, swimming pools) Fecal-oral (e.g., through food handlers, people [amboss.com]

INTRODUCTION: Though giardiasis is an important public health problem in Ghana, several aspects of its epidemiology, particularly the molecular epidemiology has not been investigated adequately. [ncbi.nlm.nih.gov]

The pathophysiology may arise from enzyme or active transport deficiencies, synergy with intestinal bacteria or an immunopathological process. Diagnosis is made by microscopic identification of cysts or trophozoites in small bowel samples or faeces. [karger.com]
