Plasma CK concentrations have been widely used as the primary muscle enzyme marker for diagnosis and progression of myositis. Recently, total CK and CK-MB serum concentrations have been compared to, and used in conjunction with, serum concentrations of aspartate aminotransferase in diagnosis of myositis. The algorithmic use of CK, AST, and aldolase plasma concentrations to diagnose and categorize patients with myopathy may be a useful method of diagnosing specific muscle disease without invasive procedures. CAIII, as a specific marker for skeletal muscle damage, may replace CK as the enzyme of choice in diagnosis and progression of myositis and other muscle disease. Additional studies are required to determine the usefulness of carbonic anhydrase for the diagnosis and assessment of myositis.

The effects on goats of Calotropis procera latex given by different routes of administration were investigated. The administration of latex at 1 ml/Kg body weight via the oral route or at 0.005 ml/Kg body weight/day via the intravenous or intraperitoneal route caused death of the goats between 20 minutes and 4 days. When the small dose of latex (0.005 ml/Kg body weight/day) was given by the oral route or intramuscular route no death among the goats occurred. Nervous signs, frequent urination, frothing at the mouth, dyspnoea and diarrhoea were the main features in goats given latex by the oral, intravenous or intraperitoneal route. Lameness was observed in goats given latex via the intramuscular route. Lesions were widespread congestion and haemorrhage, pulmonary cyanosis, enterohepatonephropathy, peritonitis (in goats receiving latex via i.p. route) and haemorrhagic myositis at the site of latex injection. These changes were accompanied by increases in the activities of serum GDH, LDH, ALP, GGT and AST and in the concentrations of cholesterol, urea and creatinine and decreases in the level of total protein.

Pharmacologic lipid-lowering interventions should be monitored periodically to assess efficacy and safety parameters. Statins are usually well-tolerated drugs and major side effects include increased serum liver and muscle enzymes (AST, ALT, CK). Treatment should be stopped or diminished in case of significant increase of AST or ALT (> 3x ULN), or CK (> 10x ULN). Other lipid lowering agents may also produce hepatotoxicity or myositis, especially in association with statins (fibrates and nicotinic acid) or in presence of metabolic abnormalities (thyroid, liver or renal disorders). Nicotinic acid can also increase glucose and uric acid plasma levels. Laboratory tests might be performed prior to hypolipidemic drug treatment and should be repeated every three months during the first year and then at 6-mo intervals. Shorter intervals should be recommended in individual cases.

Benign acute childhood myositis (BACM) is characterised by sudden calf pain and inability to walk. We analyzed the characteristics of seven boys and two girls with BACM treated in the Pediatric Department from April 2005 to March 2009. The mean age at onset of symptoms was 7 +/- 2 years. Two boys were hospitalized twice for BACM. All cases occurred in winter or spring. 7 out of all admissions were clustered together in one week long periods. Patients demonstrated prodromal symptoms of flu-like illness followed by the sudden onset of difficulty in walking. One girl additionally complained of a painful right hip. Four patients received inosine pranobex for prodromal viral infection before the clinical onset of myositis. In all cases, creatine phosphokinase (CPK; the highest value at 8988 U/l) and aspartate aminotransferase (AST; the highest value at 329 U/l) values were elevated. The serum concentration of myoglobin was elevated in five out of six tested patients (the highest value at 2172 microg/l). The following haematological abnormalities were detected: leucocytopenia (the lowest WBC 1.35 x 10(3)/microl), neutropenia, and trombocytopenia. All patients made a rapid recovery within 1 to 5 days. Pediatricians and emergency medicine specialists must be aware that BACM is a self-limiting disorder with the acute onset of inability to walk, elevated CPK and AST levels, and transient haematological abnormalities. There is no sufficient data from clinical reports on immunostimulant use before the onset of BACM.

The new antivirals clevudine, telbivudine and emtricitabine may be potent agents for the treatment of hepatitis B virus (HBV). However, there have been no reports on serious adverse events associated with the use of clevudine. A son and his mother both had HBV infection (ages: 27 and 47 years, respectively), and they had received antivirus treatment with clevudine (30 mg daily). They developed progressive weakness of the lower extremities and difficulty arising from the ground. Both the patients had symptoms for the previous 3 approximately 4 months in process of 14 approximately 17 months of clevudine therapy. The physical examinations showed positive Gower's sign, a decreased gait velocity and symmetrical proximal weakness (MRC grade 4/5). Their blood tests at admission revealed elevated or positive HBs Ag, HBV DNA, AST, ALT, creatine kinase, LDH, myoglobin and CK-MB. For both patients, the electrodiagnostic studies indicated myopathy and the pathologic findings of biopsied muscles revealed myositis. Drug-induced polymyositis was suspected and the clevudine was finally withdrawn. The muscle weakness and laboratory findings were improved for both patients after conservative care. We report here on the first cases of polymyositis that may have been caused by administering the new nucleoside analog clevudine for treating HBV infection.

Inflammatory myositis is reported in 4-16% of adult systemic lupus erythematosus (SLE) patients. The aim of this study was to determine the prevalence of myositis in a cohort of pediatric SLE patients in the southeastern United States. A retrospective chart review was performed of 55 SLE patients evaluated by Pediatric Rheumatologists in Alabama since January 1, 2008. Patients were defined as having myositis if they satisfied one of the following categories: 1) Proximal muscle weakness on exam with lower extremity muscle edema on MRI; 2) Proximal muscle weakness with elevation in CK, AST, aldolase, or LDH muscle enzymes; or 3) Patient reported weakness or muscle pain and an elevated CK. Inflammatory myositis was present as a feature of SLE in 31% (n = 17) with a 95% confidence interval of 19-45%, statistically different from the reported rates of 4-16% (p < 0.0001). Myositis was positively associated with the presence of anti-ribonucleoprotein antibodies (p = 0.009). Negative associations with myositis were the presence of anti-double stranded DNA antibodies (p = 0.02) and hematologic disorders (p = 0.02). Thus, in the state of Alabama, pediatric SLE myositis is present at a statistically higher rate than previously published values of adult SLE myositis, possibly reflecting geographic (genetic or environmental) and/or age-of-onset related influence(s).

The most common microorganisms isolated from septic arthritis are Staphylococcus aureus and streptoccocci. Septic arthritis due to Salmonella spp. are rare and the most commonly isolated species are S.Choleraesuis and S.Typhimurium. However the number of septic arthritis cases due to S.Typhi is low in literature. In this report, septic arthritis of hip due to S.Typhi in a multiple sclerosis patient who was under steroid therapy, was presented. A 25-year-old female patient was admitted to our clinic with the complaints of fever, left hip pain, standing and walking disability for 10 days. Her anamnesis revealed that she had had a multiple sclerosis attack and underwent triple pulse steroid therapy. Laboratory findings were as follows; WBC count: 16.300/mm3 (70% polymorphonuclear leukocyte), hemoglobin: 10.6 g/dl, erythrocyte sedimentation rate: 140 mm/hour, CRP: 28.7 g/L, AST: 86 U/L and ALT: 77 U/L. In lumbosacral magnetic resonance imaging, trochanteric bursitis and generalized myositis were detected in left hip joint compatible with septic arthritis. S.Typhi was isolated from patient's blood and operational tissue samples. Serum Salmonella TO and TH titers were found as 1/400 and 1/200, respectively. Antibiotic susceptibility test was performed by disk diffusion method, and the isolate was found susceptible to ampicillin, chloramphenicol, ceftriaxone, ciprofloxacin and trimethoprim-sulphametoxazole. The patient was treated by surgery and also by two weeks parenteral (2 x 400 mg) and 6 weeks oral (2 x 500 mg) ciprofloxacin treatment. Six months follow-up of the patient revealed that clinical, radiological and laboratory findings were normal. As far as the national literature was considered, this was the first S.Typhi septic arthritis case involving the hip joint and demonstrating bacterial growth both in blood and operational tissue. The presentation of the infection as arthritis plus diffuse myositis and bursitis, is also noteworthy.

Benign acute childhood myositis (BACM) is a syndrome classically occurring in children during the convalescent phase from a febrile upper respiratory tract infection, most commonly after influenza B. BACM can cause difficulty walking due to severe calf pain. Laboratory results show increased serum creatinine kinase and AST. Although alarming, BACM is self-limiting with symptoms disappearing within a week. Herein, we described a case series of BCAM in children in two cities in Poland during the influenza outbreaks in 2012/2013 and 2014/2015. We discussed the presentation and the clinical workup and examinations of the myositic syndrome. In addition, we evaluated the association of BACM with influenza B. We detected specific IgG against influenza B virus in 83% of the children diagnosed with BCAM. Reports from the National Institute of Public Health - National Institute of Hygiene in Warsaw, Poland confirmed a high rate of influenza B cases during both epidemic seasons in question.
