Individuals with diabetes mellitus may excrete small amounts of protein in the urine which may signal the beginning of reduced glomerular filtration. Stabilizing the blood glucose level at this time may delay progression of diabetic nephropathy. Women in the last month of pregnancy may develop proteinuria as the first sign of impending eclampsia. Eclampsia is the gravest form of toxemia of pregnancy. The presence of protein in this situation must be evaluated by the physician in conjunction with other clinical symptoms.Benign transient proteinuria may be the result of: exposure to cold, strenuous exercise, dehydration, and/or high fever. Benign transient proteinuria may also occur during the acute phase of a severe illness.

A screening test for bilirubin in the urine is included in most urine dipsticks and may be present when liver disease or damage is suspected. Bilirubinuria can be detected before other clinical symptoms such as jaundice are present or recognizable. The detection of small quantities is very important in early diagnosis of obstructive and hepatic jaundice. This test is also useful in the differential diagnosis of obstructive jaundice (positive for bilirubinuria) vs. hemolytic jaundice (negative for bilirubinuria).

Kornbluth AA. Danzig JB. Bernstein LH.: Clostridium septicum infection and associated malignancy. Report of 2 cases and review of the literature. Medicine. 68(1):30-7, 1989We report 2 patients with myonecrosis due to Clostridium septicum and associated colon carcinoma and have reviewed the English language literature for all reported cases of atraumatic C. septicum infection. A total of 162 cases of C. septicum infection have been reported.Eighty-one percent of these patients had an associated malignancy. Thirty-four percent of all patients had associated colon carcinoma, while 40% had a hematologic malignancy. Thirty-seven percent of reported patients had an occult malignancy at the time of their infection with C. septicum. In many patients, the portal of entry was found in the large intestine.In a particularly lethal form (79% mortality) of C. septicum infection, known as "distant myonecrosis," infection metastatic from the initial site of infection causes severe myonecrosis, gangrene, and often death within hours of clinical detection. Overall, survival of patients with C. septicum infection is only 35%.Review of all cases of C. septicum infection suggests several conclusions. 1) Patients with malignancy, particularly colonic or hematologic, and patients with cyclic neutropenia who develop signs and symptoms of sepsis, especially with associated findings of abdominal pain or pain in an extremity, should be treated for possible clostridial infection. 2) C. septicum infection does not appear to be a result of a single specific defect in either humoral or cell-mediated immunity. Rather, it may occur in patients who are granulocytopenic and therefore prone to an enterocolitis. 3) Patients in whom an infection with C. septicum is found must undergo a vigorous search for malignancy following ac

A first degree burn involves only the skin's outer layer (the epidermis) and is the least severe.Symptoms are redness, pain, and mild swelling.

Hemophilia B is a deficiency of coagulation factor IX. Found almost exclusively in males, its pattern of inheritance is sex-linked recessive. This disorder presents almost identically to Hemophilia A in terms of symptoms, and has a very similar pattern of inheritance. Be sure to keep in mind that while similar, Hemophilia A and B are caused by a deficiency in different coagulation factors. The treatment of Hemophilia B involves therapeutic administration of Factor IX concentrates.

Acquired Immunodeficiency syndrome (AIDS) is caused by the Human Immunodeficiency virus (HIV). When HIV enters a person's bloodstream, it attacks and kills the T-helper lymphocytes, which are essential to the body in fighting off infections. As these cells are lost, so is the body's ability to fight infection. Possibly months after the initial infecting episode, an infected person develops a mononucleosis-like illness lasting a week or two. A person may then be free of symptoms for years. But as the T-helper cells die, the person becomes vulnerable to many serious infections. The expected mortality is 100%, and there is no vaccine available to develop specific immunity.

Most likely means of dissemination: As an aerosolPrimary route of entry: InhalationGeneral signs and symptoms: High fever, extreme lethargy, severe headache, severe backache, severe abdominal pain, with a rash that starts as red bumps but quickly develops into small, itchy blisters.   Photo courtesy of the CDC archives.

Most likely means of dissemination: AerosolPrimary route of entry: InhalationGeneral signs and symptoms: High fever, chills, headache, coughing up of blood (hemoptysis), and toxemia, progressing rapidly to difficulty in breathing (dyspnea), and bluish discoloration of the skin and mucous membranes (cyanosis).There is another form of the disease called “bubonic plague”. While it is caused by the same organism, it is not transmissible through human contact. Pneumonic plague is transmissible through human contact.

Most likely means of dissemination: Solid or aerosolPrimary route of entry: Inhalation, absorption, or ingestionGeneral signs and symptoms: Sudden fever, chills, headaches, muscle aches, joint pain, dry cough, progressive weakness, and pneumonia.The disease is not transmissible through human contact.  When used as a WMD, infection would be acquired by handling infected material, eating or drinking contaminated food or water or by breathing in the bacterium.

 Example: Phosgene Physical Properties: Heavy gas, smells like fresh cut hay. General Signs and Symptoms: Coughing and choking, followed by tightness in chess, nausea, vomiting and headache. Death is due to the accumulation of fluid in the lungs. Relative Rate of Action: Immediate in high concentrations to several hours in low concentrations.

Examples: Tabun, SarinPhysical Properties: Colorless liquid, usually odorless, but may have a fruity smell.General Signs and Symptoms: Difficulty in breathing, contraction of the pupils, blurred vision, headache, nausea, convulsions, and eventually death.Relative Rate of Action: Rapid, within minutes.    Photo courtesy of the Wikimedia Commons.

After the marrow is evaluated, the diagnosis is established and extent of the disease is determined. Follow up bone marrow examinations may be needed to monitor changes in the marrow following treatment or when signs and symptoms of relapse occur. To summarize, a bone marrow examination can provide valuable information to aid in the diagnosis of a variety of disorders. Due to the expense involved and the discomfort to the patient, clear indications of need should be present before this examination is undertaken.

CPT (Current Procedural Terminology) codes are used to describe specific tests or services. The amount of payment for a test is dependent on the CPT code. It is against the law to use the wrong CPT code for a test for the purpose of causing or increasing payment for a test. ICD-9CM (International Classification of Disease, 9th Edition, Clinical Modification) codes are used to classify diseases and conditions, and describe signs, symptoms and medical circumstances. ICD-9CM codes are used to indicate the medical necessity of a particular test. It is against the law to use the wrong ICD-9CM code for the purpose of causing or increasing payment for a test.

ICD-9CM (International Classification of Disease, 9th Edition, Clinical Modification) codes are used for the classification of disease and conditions and for describing signs, symptoms and medical circumstances.These codes are used to indicate the medical necessity of a particular test.ICD-9 codes can only be supplied by the ordering physician or a representative of that physician. "Code steering" means to steer or direct a physician to supply an ICD-9 code that is payable. ICD-9 codes cannot be used from a previous laboratory order. If a physician supplies a narrative description instead of an ICD-9 code the laboratory must accurately translate that code using only certified coders.It is against the law to use the wrong ICD-9 code for the purpose of causing or increasing payment for a test.

This is the most important section of all. It provides information on how the chemical could affect you. Is it a carcinogen? How can it enter your body? What are the signs and symptoms of overexposure to the chemical? What first aid procedures should be used in case of an accident?

Formaldehyde exposure as low as 0.1 ppm can cause: Skin irritation Tearing of the eyes Airway irritation Headaches and dizziness

Observe the patient carefully during the procedure and be on the lookout for reactions such as nausea and vomiting. If these or other symptoms persist, contact the patient’s physician. You may need to terminate the test. Of course, always follow your institution’s specific procedure for performing glucose tolerance tests.

Elliptocytes can vary in appearance from slightly oval to thin pencil-shaped forms. Less than 1% of red cells in normal blood are oval. Many examples of elliptocytes can be seen in this smear from a patient with hereditary elliptocytosis(HE). All cases of HE are associated with weakening of membrane skeleton and defective association of proteins that hold the skeleton together. The function of elliptocytes appear to be unaffected in most cases. Notice that the cells vary in shape from slightly oval to cigar-shaped. The largest percentage of elliptocytes is seen on smears from patients with hereditary elliptocytosis. Since many of these patients have no symptoms, the presence of elliptocytes on the smear may be the only diagnostic feature.

The natural history of TB infection is usually followed by an immune response and latency after exposure. In about 5-10% of cases, the latent period progresses to an active infection.The organism that causes TB infection is Mycobacterium tuberculosis. This organism is pictured in the photograph to the right as observed when stained with acridine orange stain. Infection occurs when a susceptible person inhales droplet nuclei containing Mycobacterium tuberculosis and the organism reaches the alveoli of the lungs.About 2-12 weeks after infection, the immune system limits multiplication of additional bacteria and the immunological test becomes positive.Latent tuberculosis infection (LTBI) is the stage when the viable organism remains in the body, and the patient has no symptoms and is non-infectious.Most infected persons do not experience clinical illness and are noninfectious. About 5-10% of persons infected with Mycobacterium tuberculosis who are not treated will develop TB during their lifetime. The risk for progression is highest during the first several years after infection.TB infects the lungs most often; however, it can infect almost any organ in the body, including bones and joints.

Symptoms of TB can mimic other diseases and the physician must consider the patient's history as well as physical symptoms before making a final diagnosis.

A 14 year-old boy came to the physician's office with a sore throat that progressively worsened over a three day period. His posterior pharynx was swollen ,shiney and erythematous. The boy complained of pain on swallowing. His temperature was 98.5F. A rapid direct streptococcal antigen test was positive. However, his symptoms did not subside over the next two days while on antibiotic therapy. Anorexia and nausea were persistent and compounded by a frontal headache. Cervical lymph nodes became noticeably enlarged. The results of the CBC were: WBC 11.9/mm3 with 17% segmented neutrophils, 5% bands, 72%(60% atypical--see photograph)lymphocytes and 6%monocytes. All red cell findings were normal. A monospot test was positive. This is a case of group-A streptococcal infection superimposed on infectious mononucleosis. Symptoms subsided in 3 weeks following completion of the antibiotic therapy.
