We report the clinical and laboratory characteristics of measles infection in an unselected group of 461 young adults. Otitis media was diagnosed in 9.8%, sinusitis in 4.1%, pneumonia in 3.7%, and keratitis in 3.3% of the patients. Minor T-wave changes on electrocardiogram were observed in only 0.7% and jaundice in 0.4%. Elevated liver enzymes were found in 51% of the patients. Creatine kinase (CK) MM fraction was high in 44%. Traces of myoglobin were found in the urine of 14% of those with a high CK, and of the 13 patients with the higher CKs, 12 had an abnormal serum aldolase. We emphasize several points of interest in this large and unselected group of young adults. There was 1) possible evidence of rhabdomyolisis in some of our patients; 2) a lower rate of electrocardiogram abnormalities than previously reported; 3) no evident correlation between initial laboratory values and subsequent complications; and 4) lack of a clinical or laboratory difference between patients who had been vaccinated with an attenuated virus during childhood and those who had not.

Initial hypermyoglobinemia was found in patients with cancer of lungs, large intestine and rectum. Within early postoperational period under favourable conditions moderate increase in content of free myoglobin was detected, most pronounced in patients with lung cancer. Maximum concentration of myoglobin was estimated within first postoperational day, normalization occurred within 3-4 days after the operation. In patients with postoperational complications (peritonitis, pneumonia, sepsis, etc) increase in content of myoglobin was more distinct (1.6-2-fold) and was maintained within the longer period. Increase in content of blood plasma myoglobin occurred usually before manifestations of clinical symptoms related to postoperational complications.

Measurements were made of serum and urine myoglobin in 48 patients with leptospiral jaundice (LJ) and 56 patients with various acute infections. At the height of LJ blood myoglobin level reached 28.96 +/- 4.3 micrograms/l (normal concentration 0.315 +/- 0.002 microgram/l). Compared to acute pneumonia, acute viral hepatitis, tonsillitis, erysipelas, diphtheria, health values, the ratio of serum myoglobin to urine myoglobin in leptospirosis made up 45.25 against 5.4, 4.8, 6.8, 3.7, 1.8 and 1.3, respectively. A relationship was found between concentrations of myoglobin, bilirubin, creatinine in the blood and leptospirosis severity. Elevation of serum myoglobin as a manifestation of specific myositis is pathognomic for leptospirosis and contributes to the onset of acute renal failure and disturbance of bilirubin metabolism. Quantitation of blood myoglobin may be helpful as an additional test for leptospirosis severity.

We encountered a case of psittacosis accompanied with rhabdomyolysis in a 66-year-old woman admitted to our hospital because of myalgia, fever, diarrhea, and disorientation. A chest CT scan showed air-space consolidation and ground-glass attenuation in the left lung. Laboratory findings showed elevation of CPK, myoglobin, and aldolase, consistent with rhabdomyolysis. She recovered after administration of intravenous erythromycin and steroid pulse therapy. Psittacosis was diagnosed from the history of exposure to pigeons and from elevation of the IgG titer for Chlamydia psittaci. Rhabdomyolysis is associated with some kinds of viral or bacterial infections. But few case reports have been found in the case of psittacosis. The mechanism whereby rhabdomyolysis complicates psittacosis is unknown. We suggest that psittacosis should be added to the list for differential diagnosis, when rhabdomyolysis develops in a patient with pneumonia.

Legionella pneumophyla is the agent responsible of Legionnaire's disease. It appears as a severe pneumonia and often requires admission in Intensive Care Unit. In literature, renal failure is reported to occur in 15 percent of Legionnaire disease and this event induce a mortality over 50% of these cases. The authors describe a case of Legionnaire's pneumonia with respiratory failure, rhabdomyolysis and acute renal failure. Patient was a female, 61 yrs old, admitted to our hospital because of fever (38 degrees-38.5 degrees C), severe respiratory failure (pH = 7.49, PaCO2 = 23.1 mmHg, PaO2 = 56.7 mmHg), oliguria (< 200 ml/24 h); chest x-rays and computed tomography (TC) showed a pneumonia at right lower lobe. Among other things, in blood analysis was noted the following values: BUN = 47 mg/dl, creatinine = 2.1 mg/dl, Na+ = 133 mmol/L, Cl- = 97 mmol/L, Ca+ = 7.2 mg/dl, K+ = 5.8 mmol/L, AST = 213 U/L, ALT = 45 U/L, LDH = 1817 U/L, CPK = 16738 U/L, CPK-MB = 229 U/L, myoglobin > 4300 ng/ml., leucocyte count = 17,500/mmc (N = 92%, L = 3%, M = 5%), positive anti Legionella IgG and IgM (IgG > 1:64, IgM > 1:96), evidence of Legionella soluble antigen in the urine analysis. Therapy with clarytromicyne (500 mg b.i.d i.v.) and rifampicin (600 mg/die i.v.) was begun; computed tomography showed after six days an improvement of pulmonary lesion but, in the following days, health status and blood analysis got worse. Patient went on antibiotics and underwent haemotherapy (Hb: 8 gr/dl), haemodialysis because of acute renal failure but healthy status worse furthermore and she died on 18th days after admission. This case point out rhabdomyolysis with acute renal failure is suggestive for Legionnaire's disease and is associated with high rate of mortality.

Toxoplasma gondii is a Apicomplexa obligate intracellular protozoan parasite that infects up to a third of the world's population. In most humans infected with T. gondii, the disease toxoplasmosis is asymptomatic. However, T. gondii causes blindness, severe neurological disorders, hepatitis, and pneumonia in immunocompromised patients, and severe damage to the fetus. Here, we postulate that the colonization of the retina, heart, and skeletal muscle by T. gondii may reflect the role of neuroglobin (Ngb) and myoglobin (Mb) to protect the parasite from the toxoplasmacidal effects of nitric oxide (NO). This is based on the knowledge that Ngb and Mb catalyzes NO oxidation yielding the harmless nitrate. The postulated protective role of Ngb and Mb on the viability of T. gondii is reminiscent of that postulated for hemoglobin (Hb) and Mb in protecting intraerythrocytic Plasmodia and T. cruzi in cardiomyocytes, respectively, from the parasiticidal effect of NO. Therefore, undesirable pathogen protection by pseudo-enzymatic NO scavenging may represent a new unexpected function of members of the Hb superfamily.

An immature Baird's tapir (Tapirus bairdii) with a history of seizure-like episodes developed signs of respiratory disease. The initial clinical diagnosis was pneumonia, and antibiotic therapy was started. The animal failed to improve after 14 days of therapy and developed unilateral, bloody nasal discharge. Endoscopic examination and radiography revealed a soft tissue mass in the nasopharynx depressing the soft palate. The tapir died 32 days after initial presentation. Histologic examination of the mass demonstrated a mesenchymal tumor composed of spindle cells with elongate nuclei forming densely packed fascicles. The neoplastic spindle cells showed prominent cross-striations. Immunohistochemistry revealed the cells to be positive for desmin and myoglobin, but negative for smooth muscle actin, confirming diagnosis of rhabdomyosarcoma. Embryonal rhabdomyosarcoma is the most common nasopharyngeal soft tissue tumor of humans, and it has been reported infrequently in dogs, horses, and pigs. Neoplasia should be a differential diagnosis in cases of unilateral nasal discharge and inspiratory stridor, even in young animals.

A case of Legionella pneumophila pneumonia with rhabdomyolysis-induced acute tubulointerstitial nephritis (ATIN) and prolonged renal dysfunction is presented. The patient was a 54-year-old man, admitted with high-grade fever, ataxia and muscle dysfunction; chest roentgenogram showed multilobular infiltrations. L pneumophila was detected in his sputum and urine, by PCR and by culture, and L pneumophila pneumonia was diagnosed. Despite antimicrobial treatment, he developed renal failure and rhabdomyolysis. Renal biopsy showed the presence of myoglobin casts that occluded the distal tubuli and tubulointerstitial nephritis, leading to the diagnosis of rhabdomyolysis-induced ATIN. Renal function subsequently normalised, and he was discharged. This is believed to be the first pathological evidence of involvement of rhabdomyolysis in legionellosis-associated ATIN.

Legionella pneumophila is a cause of both community- and hospital-acquired pneumonia and might cause high morbidity and mortality. Therefore, early diagnosis and treatment with appropriate antibiotics is crucial. Many clinical and laboratory abnormalities can be observed in the course of Legionella pneumonia. In this study, we aimed to present simultaneously increased serum ferritin and myoglobin level in a legionella case with reference to the relevant literature.

Creatine kinase-MB (CK-MB), cardiac troponin I (cTnI) and myoglobin (Mb) are biochemical markers of myocardial injury; however, Mb is more abundant in skeletal muscles. The present study involved analysis of these markers in pericardial and cerebrospinal fluids (PCF and CSF) from serial medicolegal autopsy cases (n=295, within 48h) to examine their efficacy in determining the cause of death. Although these markers showed a slight postmortem time-dependent elevation, except for CK-MB in CSF, the distribution depended on the cause of death. Mb levels in PCF and CSF were higher in fatal hyperthermia (heat stroke) and methamphetamine abuse, and CK-MB in both fluids was also higher in the latter. In psychotropic drug intoxication, CK-MB, cTnI and Mb were higher in PCF, but only cTnI was elevated in CSF. In electrocution and cerebrovascular disease, each marker was higher in PCF and also relatively high in CSF. PCF cTnI level was higher in acute pulmonary embolism without significant elevation of any other markers, whereas CSF CK-MB was higher in acute blunt brain injury death and methamphetamine abuse. In most cases of delayed brain injury death, hypothermia (cold exposure) and pneumonia, these markers were low or intermediate in both PCF and CSF; however, sudden cardiac death, asphyxiation and fire fatality cases showed few characteristic findings. These observations suggest that combined analyses of these markers in postmortem PCF and CSF, in addition to blood samples, are helpful for evaluating the severity of myocardial and/or skeletal muscle damage in death processes, in particular for investigating deaths due to hyperthermia, hypothermia, electrocution and intoxication.
