Cutaneous polyarteritis nodosa is an infrequent necrotizing vasculitis of small and medium-sized arteries, with a recurrent and chronic course, that can be associated with fever, arthralgia, myalgia and neuropathy without visceral involvement. We report a cutaneous polyarteritis nodosa case.

A substudy analysis was conducted to determine the clinical characteristics associated with symptomatic, laboratory-documented influenza (LDI) among 2215 veterans with chronic obstructive pulmonary disease who participated in Department of Veterans Affairs Cooperative Study 448 and who received trivalent inactivated influenza virus vaccine with or without intranasal live-attenuated, cold-adapte...

Eosinophilia-myalgia syndrome was described in 1989 in patients who presented progressive and incapacitating myalgia and eosinophilia in blood, fluids and secretions. Most patients report previous L-tryptophan intake. Respiratory manifestations are found in up to 80% of the cases, occasionally as the only manifestation. Treatment includes drug discontinuation and administration of corticosteroi...

Rhabdomyolysis is a rare condition caused by the proteins of damaged muscle cells entering the bloodstream and damaging the kidneys. Common symptoms of rhabdomyolysis are muscle pain and fatigue in conjunction with dark urine; kidney damage is a common symptom among these patients. We present a case of a 23-year-old woman who displayed myalgia in the upper extremities caused by low-intensity an...

In 2012, a female wildlife biologist experienced fever, malaise, headache, generalized myalgia and arthralgia, neck stiffness, and a sore throat shortly after returning to the United States from a 6-week field expedition to South Sudan and Uganda.

Human parechovirus has rarely been shown to cause clinical disease in adults. During June-August 2008, a total of 22 adults sought treatment at Yonezawa City Hospital in Yamagata, Japan, for muscle pain and weakness of all limbs; most also had fever and sore throat. All patients received a clinical diagnosis of epidemic myalgia; clinical laboratory findings suggested an acute inflammatory proce...

The aim was to assess mRNA and/or protein levels of heat shock proteins, cytokines, growth regulating, and metabolic proteins in myalgic muscle at rest and in response to work tasks and prolonged exercise training. A randomized controlled trial included 28 females with trapezius myalgia and 16 healthy controls. Those with myalgia performed ~7 hrs repetitive stressful work and were subsequently ...

Acute pancreatitis, neuroleptic malignant syndrome (NMS) and epileptic seizures are all known to be rare complications of clozapine-treatment (Steinert et al. 2011, Tenner 2014, Belvederi Murri et al. 2015). For amisulpride, only seven cases with NMS (Belvederi Murri et al. 2015) including one case with seizures (Musshoff et al. 2013) have been described yet. Recently, via a German pharmacovigi...

The frequency of myopathy in hypothyroidism ranges from 30 to 80%. The major symptoms related are weakness, muscular cramps and myalgia. The pseudohyperthrophic form is called Hoffman's syndrome. The electrophysiological study reveals myopathy, neuropathy or mixed pattern. Laboratorial investigation generally shows increased levels of muscle enzymes and low serum thyroid hormones, with thyrotro...

A wide spectrum of muscle disorders caused by Coxsackie B virus, ranging from acute nonspecific myalgia to rhabdomyolisis have been described. Arthritis in not widely recognised as an either manifestation of Coxsackie virus infection, and only ten patients has been reported previously. A case of polymyositis and polyarthritis associated with primary Coxsackie B infection in a 6-year-old girl is...
