Review[Lumbosacral facet syndrome: functional and organic disorders of lumbosacral facet joints].
Disorders of lumbosacral (LS) facet joints are manifested by low back pain with or without referred leg pain and decreased mobility of the LS spine (LS facet syndrome). The most frequent causes of LS facet syndrome are functional disorders (functional blockade or dysfunction of facet joint=reversible restriction of facet joint movements caused by meniscoid entrapment) and degenerative changes of facet joints while the others are less frequent (spondyloarthropathies, infection, tuberculosis, synovial cyst, injury). Although it has been proven that the facet joints are one of the most frequent sources of chronic low back pain (15-45%), the fact is that the facet syndrome has been frequently overlooked in patients with chronic low back pain. ⋯ Acute LS facet syndrome caused by dysfunction of facet joints responds very well to manual therapy. The most important therapeutic options in patients with chronic LS facet syndrome caused by degenerative changes and/or dysfunction of facet joints are manual therapy, kinesiotherapy (flexion exercises), therapeutic blocks and radiofrequency denervation. The article describes etiopathogenesis, clinical manifestations, diagnosis, differential diagnosis and therapy of LS facet syndrome with emphasis on functional disorders of facet joints that can cause particular diagnostic and therapeutic problems.

Review[Vitamin D: vitamin from the past and hormone of the future].
In the last decade there has been a rising recognition of potential clinical significance of the vitamin D. Vitamin D regulates about 3% of the human genome. ⋯ In this paper vitamin D metabolism and up to date knowledge of vitamin D function in calcium metabolism, muscular function and in prevention of infection, malignancy, autoimmune and cardiovascular diseases is presented. Reasons for pandemic vitamin D deficiency and guidelines for vitamin D supplementation are given.

Sugammadex is a new pharmacological agent for neuromuscular block reversion. It is a cyclic oligosaccharide, a gamma cyclodextrin with lipophylic inner coat that enables forming of stable complexes with steroidal neuromuscular blocking drugs, especially with rocuronium. A physical encapsulation of the relaxants is a novel elimination pathway and it produces fast and complete reversion of both deep and shallow neuromuscular block. ⋯ After the adjusted dose of sugammadex was given, the duration of action of rocuronium can be made as short as that of succinylcholine. This characteristic is especially important in the 'can't intubate, can't ventilate' situation and after surgical procedure was unexpectedly finished. Clinical studies involving more patients are needed to show the real risk-benefit profile and safety in the special patients' populations.

Asthma exacerbation is characterized by a rapid and progressive worsening of symptoms, mainly dyspnea, cough, wheezing and chest tightness. The intensity of an exacerbation may vary form a mild, transient worsening marked by a cough and moderate shortness of breath to a very severe and life-threatening condition. The clinical features of asthma include increased rate of breathing, cough, and prolonged and difficult expiration. ⋯ The strategy of the treatment of an asthma exacerbation includes the repeated administration of rapid-acting inhaled bronchodilators, the early introduction of systemic glucocorticoids and oxygen supplementation. The treatment is aimed to resolve the airflow limitation and ameliorate the hypoxemia, as quickly as possible. Mild exacerbations could be treated in general practice while the severe ones should be treated in emergence units.

The prime goal of this paper is to offer an overview of main scientific points in epidemiology, genetics, pathogenesis, clinical course and therapeutic strategies in stiff person syndrome (SPS). This syndrome is characterized by progressive muscle rigidity and painful muscle spasms. Three major forms of SPS are described, according to the pathophysiologic basis, autoimmune, paraneoplastic and idiopathic SPS. ⋯ The therapeutic approaches are focused on symptomatic therapy managing the muscle spasm and on possible immunomodulatory procedures to attenuate an autoimmune reaction. Two cases of SPS are reported in the Republic Croatia since 2005. Although it is a rare medical condition, SPS is of clinical importance, especially because it may be the first sign of an underlying undiagnosed malignant disease or if the anesthesia is necessary in SPS patient.
