Diagnosis of Gilbert’s Syndrome

4 July, 2011

Gilbert syndrome is a genetic condition and this autosomal recessive condition is characterized by intermittent jaundice in the absence of hemolysis or liver disease.
The hyperbilirubinemia is mild. By definition, bilirubin levels in Gilbert syndrome are lower than 6 mg/dL, though most patients exhibit levels lower than 3 mg/dL. Gilbert syndrome is the result of a genetic mutation in the promoter region of a gene for the enzyme UGT1A (bilirubin–uridine diphosphate glucuronyl transferase).

Scoring the BODE Index

28 June, 2011

The BODE is a multidimensional index designed to assess clinical risk in people with chronic obstructive pulmonary disease (COPD). It combines four important variables into a single score: (B) body mass index; (O) airflow obstruction measured by the forced expiratory volume in one second (FEV1); (D) dyspnoea measured by the modified Medical Research Council (MRC) scale; and (E) exercise capacity measured by the 6-minute walk distance (6MWD). Each component is graded and a score out of 10 is obtained, with higher scores indicating greater risk. The BODE index reflects the impact of both pulmonary and extrapulmonary factors on prognosis and survival in COPD.

Traditional Diagnostic Criteria for Hereditary Hemochromatosis

18 June, 2011

Hereditary hemochromatosis has been traditionally defined as an inherited disorder characterized by inappropriately high absorption of dietary iron, which leads to abnormal accumulation of iron in parenchymal organs. In 1996, the HFE gene was isolated on chromosome 6. Since this finding hereditary hemochromatosis has been defined by some as the presence of a homozygous defect in the HFE gene with direct or indirect evidence of iron overload.

Criteria for the Diagnosis of Borderline Personality Disorder (BPD)

26 May, 2011

Borderline personality disorder is a chronic psychiatric disorder characterized by marked impulsivity, instability of mood and interpersonal relationships, and suicidal behaviour that can complicate medical care. Identifying this diagnosis is important for treatment planning.

Revised Diagnostic Criteria for Neuromyelitis Optica (NMO)

24 May, 2011

Neuromyelitis optica (NMO; Devic syndrome) is a clinically defined, severe CNS demyelinating syndrome characterized by optic neuritis (ON) and acute myelitis; the presence of CNS symptoms outside the optic nerves and spinal cord has until recently excluded the diagnosis.

Definitions of Laboratory and Clinical Tumor Lysis Syndrome

12 May, 2011

The tumor lysis syndrome is the most common disease-related emergency encountered by physicians caring for children or adults with hematologic cancers. This syndrome occurs when tumor cells release their contents into the bloodstream, either spontaneously or in response to therapy, leading to the characteristic findings of hyperuricemia, hyperkalemia, hyperphosphatemia, and hypocalcemia. These electrolyte and metabolic disturbances can progress to clinical toxic effects, including renal insufficiency, cardiac arrhythmias, seizures, and death due to multiorgan failure.

Signs and Symptoms of Acute Radiation Sickness

25 April, 2011

Acute radiation sickness can be categorized into three phases: prodrome, latency, and illness. The Table, summarizes the constellation of hematologic, gastrointestinal, and neurologic symptoms, along with the time to onset and dose dependence, associated with each of these phases.

Diagnostic Criteria for Reiter´s Syndrome or Reactive Arthritides (ReA)

11 March, 2011
Reactive arthritis (ReA) is an inflammatory arthritis that arises after certain types of gastrointestinal or genitourinary infections. It belongs to the group of arthritidies known as the spondyloarthropathies (SpAs). The classic syndrome is a triad of symptoms, including the urethra, conjunctiva, and synovium; however, the majority of patients do not present with this classic triad. In general, there are two forms of ReA, postvenereal (Chlamydia trachomatis [Ct]) and postdysentery (Salmonella, Shigella, Campylobacter, and Yersinia), but several other bacteria have been implicated as potential causes.

Indications and Contraindications Radioiodine Treatment of Differentiated Thyroid Cancer (DTC)

23 February, 2011

Differentiated thyroid cancer (DTC) is defined as a carcinoma deriving from the follicular epithelium and retaining basic biological characteristics of healthy thyroid tissue, including expression of the sodium iodide symporter (NIS), the key cellular feature for specific iodine uptake.

Clinical Indications and Contraindications to Percutaneous Coronary Intervention (PCI)

18 February, 2011

Percutaneous coronary interventions (PCI) include percutaneous transluminal coronary angioplasty (PTCA) with or without stenting. Primary indications are treatment of angina pectoris (stable or unstable), myocardial ischemia, and acute MI (particularly in patients with developing or established cardiogenic shock).
