Flexible production system has been expanded to all sectors of economy with the change of labor market and diversification of employment. The unstable employment with irregular work has replaced stable employment with regular work. This study has investigate the impact pathway of the type of employment on health status especially ill-health symptoms experiences. Among the first Korean Working Conditions Survey data, the employee's response data was used to analyze the path way with multiple regression analysis. The result has shown the direct effect of the type of employment on ill-health symptoms experience. Indirect effect of the type of employment was found the pathway via the exposure to noise, high temperature, low temperature, dust, skin contact to chemicals, painful posture, heavy material handling, standing position, repetitive movement of hands. However the exposure to the other hazardous factors such as organic solvent, wholebody vibration, radiation, lifting people, infectious materials were not influenced by the type of employment.

Purpose: Childhood leukemia is a serious trauma affecting both adolescents and their parents, who experience painful process. However, adolescents with leukemia and their parents also experience positive changes, which is referred to as posttraumatic growth. We examined posttraumatic growth, core beliefs, impact of event, and event-related rumination in adolescents within 5 years of a diagnosis of childhood leukemia and their parents. Methods: The participants were 68 adolescents with childhood leukemia (aged 13~18 years) and their parents, who were recruited from C university hospital in Korea from May to September 2016. The Posttraumatic Growth Inventory, Core Belief Inventory, Impact of Event Scale-Revised, and Event-related Rumination Inventory were completed by the adolescents and their parents. The mean scores and correlations between variables were investigated for both set of participants. Results: Parents showed significantly higher levels of posttraumatic growth, disruption of core beliefs, impact of event, and invasive rumination than adolescents. Disruption of core beliefs and deliberate rumination were positively correlated with posttraumatic growth in both groups. Conclusion: Nursing intervention programs that involve modifying core beliefs and inducing a positive thought can help adolescents with leukemia and their parents grow after traumatic events.

Going back to basics prior to mentioning the use of antipsychotics in patients with pain, the International Association for the Study of Pain (IASP) definition of pain can be summarized as an unpleasant experience, composed of sensory experience caused by actual tissue damage and/or emotional experience caused by potential tissue damage. Less used than antidepressants, antipsychotics have also been used for treating this unpleasant experience as adjuvant analgesics without sufficient evidence from research. Because recently developed atypical antipsychotics reduce the adverse reactions of extrapyramidal symptoms, such as acute dystonia, pseudo-parkinsonism, akathisia, and tardive dyskinesia caused by typical antipsychotics, they are expected to be used more frequently in various painful conditions, while increasing the risk of metabolic syndromes (weight gain, diabetes, and dyslipidemia). Various antipsychotics have different neurotransmitter receptor affinities for dopamine (D), 5-hydroxytryptamine (5-HT), adrenergic (${\alpha}$), histamine (H), and muscarinic (M) receptors. Atypical antipsychotics antagonize transient, weak $D_2$ receptor bindings with strong binding to the $5-HT_{2A}$ receptor, while typical antipsychotics block long-lasting, tight $D_2$ receptor binding. On the contrary, antidepressants in the field of pain management also block the reuptake of similar receptors, mainly on the 5-HT and, next, on the norepinephrine, but rarely on the D receptors. Antipsychotics have been used for treating positive symptoms, such as delusion, hallucination, disorganized thought and behavior, perception disturbance, and inappropriate emotion, rather than the negative, cognitive, and affective symptoms of psychosis. Therefore, an antipsychotic may be prescribed in pain patients with positive symptoms of psychosis during or after controlling all sensory components.

The memory of pain can be more damaging than its initial experience. Several factors arc related the directions of pain memory: current pain intensity, emotion, expectation of pain, and peak intensity of previous pain. The possible mechanisms behind the memory of pain are neuroplastic changes of nervous system via peripheral and central sensitization. Peripheral sensitization is induced by neurohumoral alterations at the site of injury and nearby. Biochemicals such as K+, prostaglandins, bradykinin, substance P, histamine and serotonin, increase transduction and produce continuous nociceptive input. Central sensitization takes place within the dorsal horn of spinal cord and amplifies the nociceptive input from the periphery. The mechanisms of central sensitization involve a variety of transmitters and postsynaptic mechanisms resulting from the activations of NMDA receptors by glutamate. and activation of NK-1 tachykinnin receptors by substance-P and neurokinnin. The clinical result of peripheral and central sensitization is hyperalgesia, allodynia, spontaneous pain, referred pain, or sympathetically maintained pain. These persistent sensory responses to noxious stimuli arc a form of memory. The hypothesis of preemptive analgesia is that analgesia administered before the painful stimulus will prevent or reduce subsequent pain and analgesic requirements in comparison to the identical analgesic intervention administered after the painful stimulus, by preventing or reducing the memory of pain in the nervous system. Conventionally, pain management was initiated following noxious stimuli such as surgery. More recently, however many have endorsed preemptive analgesia initiated before surgery. Treatments to control postsurgical pain are often best started before injury activates peripheral nociceptors and triggers central sensitization. Such preemption is not achieved solely by regional anesthesia and drug therapy but also requires behavioral interventions to decrease anxiety or stress. Although the benefit of preemptive analgesia may not be obvious in every circumstance, and in many cases may not sufficient to abolish central sensitization, it is an appropriate and human goal of clinical practice.

Background: Interventional pain management (IPM) is a branch of medical science that deals with management of painful medical conditions using specially equipped X-ray machines and anatomical landmarks. Interventional physiatry is a branch of physical medicine and rehabilitation that treats painful conditions through intervention in peripheral joints, the spine, and soft tissues. Methods: A cross-sectional study was conducted using three years of hospital records (2006 to 2008) from the Physical Medicine and Rehabilitation Department at Chittagong Medical College Hospital in Bangladesh, with a view toward highlighting current interventional pain practice in a tertiary medical college hospital. Result: The maximum amount of intervention was done in degenerative peripheral joint disorders (600, 46.0%), followed by inflammatory joint diseases (300, 23.0%), soft tissue rheumatism (300, 23.0%), and radicular or referred lower back conditions (100, 8.0%). Of the peripheral joints, the knee was the most common site of intervention. Motor stimulation-guided intralesional injection of methylprednisolone into the piriformis muscle was given in 10 cases of piriformis syndrome refractory to both oral medications and therapeutic exercises. Soft tissue rheumatism of unknown etiology was most common in the form of adhesive capsulitis (90, 64.3%), and is discussed separately. Epidural steroid injection was practiced for various causes of lumbar radiculopathy, with the exception of infective discitis. Conclusion: All procedures were performed using anatomical landmarks, as there were no facilities for the C-arm/diagnostic ultrasound required for accurate and safe intervention. A dedicated IPM setup should be a requirement in all PMR departments, to provide better pain management and to reduce the burden on other specialties.

Complex regional pain syndrome Type II(CRPS) can be diagnosed by new IASP criteria in 1994. Sympathetically maintained pain may or may not be present in a patient with complex regional pain syndrome. We experienced a CRPS Type II patient who has sympathetically maintained pain as a major painful nature developed after right multiple iliac bone fracture, right femoral artery thrombosis and lumbosacral plexus injury. Combination treatment with L2, L3, L4 sympathetic ganglion block and continuous lower thoracic epidural block for 30 days were tried to get long term effect. The patient had signs of successful. sympathetic denervation of the right foot. After that pain relief was sustained until three month later.

In early stages, cancer is not usually painful. However, many patients with recurrent or metastatic cancer eventually experience pain, which becomes progressively worse. Chemotherapy, sympathetic surgery, physical therapy and nerve block can be used to control cancer pain. A 60-year old patient had severe pain of the soft palate due to squamous cell carcinoma. We successfully treated this patient with maxillary nerve block using pure alcohol by a lateral approach. Four months after maxillay nerve block, the patient is still pain free.

Headaches are one of the most common conditions associated with temporomandibular disorder (TMD). In the present paper, we evaluated the relationship between headache and TMD, determined whether headache influences the symptoms of TMD, and reported two cases of TMD accompanied by headache. Our practical experience and a review of the literature suggested that headache increases the frequency and intensity of pain parameters, thus complicating dysfunctional diseases in both diagnostic and treatment phases. Therefore, early and multidisciplinary treatment of TMD is necessary to avoid the overlap of painful events that could result in pain chronicity.

Superior hypogastric plexus block is extensively recognized as a unique nerve block method for the treatment of low abdominal pain originating from organs of the pelvic area. This block is difficult to perform on older patients, especially those with osteophyte, as they will experience a high degree of pain with this technique. Therefore we reported trans-discal superior hypogastric plexus by method of approach needle through disc. This method is less painful to the patient as compared to bilateral approach; and easier to place the needle tip at precise and proper location.
