Complex regional pain syndrome (CRPS) represents a state of constant and often disabling pain, affecting one region (usually hand) and often occurs after a trauma whose severity does not correlate with the level of pain. The older term for this condition of chronic pain associated with motor and autonomic symptoms is reflex sympathetic dystrophy or causalgia. The aim of this review, based on contemporary literature, is to show the epidemiology and etiology, proposed pathophysiological mechanisms, method of diagnosis and treatment options, prevention and mitigation of this under-recognized disease. ⋯ Physical therapy besides preventing atrophy and contractures reduces the use of analgesic therapy. Invasive approach includes stimulation of the spinal cord, peripheral nerve catheters with anesthetic and amputation that patients in severe condition gladly accept. Further research is needed to better understand the disease and more effective therapies.

Respecting the informed consent and its implementation is one of the fundamental components of high-quality health care. This article discusses the informed consent with an overview of Croatian and international legal documents and scientific studies dealing with this issue. ⋯ It is necessary to evaluate the purposefulness and quality of the implementation of the informed consent, to systematically examine respect of the patients' right to information regarding the medical procedure during treatment, to explore decision-making model in the physician-patient encounter in Croatian hospitals, to determine the content and amount of information shared between physicians and patients, to determine the content and readability of consent forms and written patient information on the medical procedure. In order to assure higher quality of the implementation of the informed consent it is necessary to define by law a list of medical procedures that require written consent and to uniform consent forms for the same medical procedures country-wide.

Review[Piriformis muscle syndrome: etiology, pathogenesis, clinical manifestations, diagnosis, differential diagnosis and therapy].
The term 'piriformis syndrome' (PS), introduced by Robinson in 1947, implies a group of signs and symptoms caused by piriformis muscle (PM) disorders. Since PM disorders lead to irritation/compression of the anatomic structures passing under its belly, the main clinical PS signs and symptoms are actually the clinical signs and symptoms of irritation/ compression of neural and vascular structures passing through the infrapiriform foramen: sciatic nerve/SN, inferior gluteal nerve, posterior femoral cutaneous nerve, pudendal nerve, inferior gluteal artery and vein and inferior pudendal artery and vein. The clinical picture is usually dominated by signs and symptoms of irritation/compression of SN (SN irritation --> low back and buttock pain, sciatica,paresthesias in distribution of SN; SN compression --> low back and buttock pain,sciatica, paresthesias and neurologic deficit in distribution of SN). ⋯ In 5-6% of patients with low back pain and/or unilateral sciatica, the pain is caused by PM disorders. PS diagnosis can be made on the basis of anamnesis, clinical picture, clinical examination, EMNG, perisciatic anesthetic block of PM and radiological exams (pelvis/PM MRI; MR neurography of LS plexus and SN). PS therapy includes medicamentous therapy, physical therapy, kynesitherapy, acupuncture, therapeutic perisciatic blocks, botulinum toxin injections and surgical treatment (tenotomy of PM, neurolysis of SN).

Use of medical preparations having no specific pharmacological activity or dummy procedures administered to patients is known as placebo. Such maneuvers are important in the pain treatment and clinical studies investigating pain mechanisms. Several recent studies have shown that placebo treatment produces measurable psychophysiological effects, characterized by changes in specific brain functions and decreased subjective pain perception. This article reviews changes observed in placebo analgesia, its intensity as compared to active compounds, and principal problems observed during the placebo treatment and in clinical trials.

Review[Coccygodynia: etiology, pathogenesis, clinical characteristics, diagnosis and therapy].
The term 'coccygodynia' means the pain in the tailbone area (os coccygis; coccyx). Due to the sitting intolerance, coccygodynia can significantly disturb the quality of life. Coccygeal disorders that could be manifested in coccygodynia are injuries (fracture, subluxation, luxation), abnormal mobility (hypermobility, anterior and posterior subluxation or luxation of the coccyx), disc degeneration at sacrococcygeal (SC) and intercoccygeal (IC) segments, coccygeal spicule (bony excrescence), osteomyelitis and tumors. ⋯ Conservative therapy includes: rest, medicamentous therapy, acupuncture, coccyx cushion, physical therapy, manual therapy (massage and stretching of the levator ani muscle; mobilization of the coccyx) and therapeutic interventions (injections of local anesthetic and corticosteroid in the painful structures; radiofrequency ablation of coccygeal discs and Walther's ganglion). Using different modalities of conservative therapy, satisfactory results are achieved in the majority of patients with coccygodynia. Coccygectomy is indicated in refractory cases, first of all in patients with abnormal mobility of the coccyx and spicules who respond best to surgical treatment.
