So far the etiology of chronic prostatitis(CP), particularly chronic nonbacterial prostatitis(NBP) or chronic pelvic pain syndrome (CPPS), remains to be elucidated. According to recent epidemiologic data, the prevalence of CP ranged from 2.5% to 16% of the world population, affecting men of all ages and all ethnic origins. Since 1990s researchers of many countries have carried out largerscaled, deeper and more extensive studies than ever before on the etiology, diagnosis and treatment of the disease, with the sponsorship and coordination of such international institutions as the International Prostatitis Collaborative Network(IPCN), the Chronic Prostatitis Collaborative Research Network of the National Institute of Health (NIH-CPCRN) and so on. The main achievements of recent years include: the etiology of CP/CPPS being a complicated multi-step and multi-factor course, the establishment of the new clinical classification system, the introduction of the National Institute of Health chronic prostatitis symptom index, the new criteria of diagnosis and standardized clinical evaluation, the primary explorations of new treatment methods and medicines, etc. Further investigations suggested are the optimization of clinical classification, the screening and verification of treatment methods and medicines for CP/CPPS, etc.

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common condition obsessing urologists and patients. It is also known as a heterogeneous syndrome, with varied etiologies, progression courses and responses to treatment. Based on the deeper insights into its pathogenesis and re-evaluation of its clinical trials, a novel phenotypic classification system UPOINT has been developed, which clinically classifies CP/CPPS patients into six domains: urinary (U), psychosocial (P), organ-specific (O), infection (I) , neurologic/systemic (N) and tenderness of pelvic floor skeletal muscles (T), and directs individualized and multimodal therapeutic approaches to CP/CPPS. This review systematically summarizes the theoretical foundation, clinical characteristics of UPOINT and treatment strategies based on the UPOINT phenotypic classification system.

Pancreatic duct stones are a common complication during the natural course of chronic pancreatitis and often contribute to additional pain and pancreatitis. Abdominal pain, one of the major symptoms of chronic pancreatitis, is believed to be caused in part by obstruction of the pancreatic duct system (by stones or strictures) resulting in increasing intraductal pressure and parenchymal ischemia. Pancreatic stones can be managed by surgery, endoscopy, or extracorporeal shock wave lithotripsy. In this review, updated management of pancreatic duct stones is discussed.

OBJECTIVETo assess the efficacy of various therapeutic principles of TCM in treating patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).

METHODSAdopting blinded controlled trial method, 218 patients with CP/CPPS were randomly assigned to 4 groups: Group A treated with Aike Decoction for smoothing Gan-qi; Group B with Bazhengsan Decoction for clearing heat and removing dampness; Group C with Qianliexianyan Decoction for promoting blood circulation to remove stasis; and Group D with placebo. The scores of NIH chronic prostatitis symptom index (NIH-CPSI), clinical symptoms, including pain, symptoms of urinary tract and quality of life (QOL), and TCM syndrome integral were estimated at the beginning, the end of the 2nd and 4th week in the study.

RESULTSCompared with the others, Group A showed a superiority in improving NIH-CPSI, scores of various clinical symptoms and TCM syndrome integral at the 2nd week, and improving NIH-CPSI, scores of pain and QOL at the 4th week (all P < 0.05), while the improvement on urinary tract symptoms and TCM syndrome integral in Group A at the 4th week were better than those in Group B and D, but insignificantly different to those in Group C, respectively. No adverse reaction occurred in Group A and D, but it did occur in the other two groups.

CONCLUSIONTCM therapy for smoothing Gan-qi shows good efficacy with quick initiating and high safety, it is an important principle for the treatment of CP/CPPS.

INTRODUCTIONBrucellosis is a public health problem that is prevalent in several developing countries.

METHODSThe clinical and laboratory characteristics of 164 cases of brucellosis in Bursa, Turkey, were retrospectively evaluated.

RESULTSThe ages of the 164 patients ranged from 15-85 years. All of the patients underwent the Rose Bengal test and 163 (99.4%) patients tested positive. 122 (74.4%) patients were diagnosed with acute brucellosis, 31 (18.9%) with subacute brucellosis and 11 (6.7%) with chronic brucellosis. Focal involvement was found in 101 (61.6%) patients. Although patients with focal involvement had a higher white blood cell count (p = 0.002), those without focal involvement had higher aspartate transaminase and alanine transaminase values, and lower platelet values (p = 0.005, 0.007 and 0.039, respectively). Spondylodiscitis was observed on imaging in 58 (66.7%) of the 87 patients who presented with back pain. Among the 118 patients who were examined within the first month of treatment, 79 (66.9%) responded to treatment. The relapse rate was 11.6% among all 164 patients.

CONCLUSIONBrucellosis should be considered as a differential diagnosis among patients who present with fever, and joint or back pain. Focal involvement should be investigated in the presence of leucocytosis, and subacute or chronic forms of brucellosis. To identify cases of spondylodiscitis, radiography should be performed in patients who present with back pain.

Chronic low back pain (CLBP), defined as low back pain persisting more than 3 months, develops in about 5~7% of those who experience low back pain anytime during the lifetime. It is associated with not only substantial functional disability in each patient, but also a great socioeconomic burden. The etiology of CLBP is usually multifactorial. Also, known risk factors related to the development of CLBP are diverse, including age, sex, genetic factors, environment, previous trauma, dissatisfaction from work, etc. The more common causes of CLBP encounteredin clinical settings are disorders related to intervertebral disc, spinal stenosis, spondylolisthesis, compression fracture related to osteoporosis, pain originating from zygapophysial, and sacroiliac joints. Less common but other important causes include metastatic lesions, infection, and myofacial pain syndromes. Here, an evidence-based literature review on nonsurgical management of CLBP is presented with a special attention focused on various therapeutic approaches based on etiologic processes and clinical presentations. Nonsteroidal anti-inflammatory drugs, alone or in combination with muscle relaxants, relieve pain and improve overall symptoms of acute low back pain, but do not usually play a role in CLBP. Tricyclic antidepressants play a role in CLBP with its analgesic effect and sleep improvement. Tramadol, a centrally acting analgesic, also provides effects on moderate to severe CLBP but careful considerations, as with opioids, are necessary to prevent side effects and should be prescribed in refractory patients. Exercise therapy has strong evidence in the management of CLBP. Moderately strong evidence supports the use of manipulation in acute back pain but not in CLBP. Evidence for epidural steroid is strong for short-term relief of CLBP and is moderate to strong for long-term relief, especially with radicular pain, when performed transforaminally. Medial branch block (MBB) has moderate effects on facet-related pain and mechanical LBP, and the radiofrequency medial branch neurotomy has strong evidence of long-term effects when done properly in patients responsive to MBB. The use of facet injections, orthoses, traction, magnets, prolotherapy, trigger point injection, or acupuncture in the management of CLBP, unlike in acute LBP, is not supported by evidence for the long-term effectiveness. Sacroiliac joint injections are not indicated in the routine management of low back pain but show moderate effects in selected patients with CLBP. Conflicting evidence exists regarding the use of transcutaneous electrical nerve stimulation. For primary care providers and for those who specialize pain management, every effort should be made to contemplate all possible factors that might have played roles in generating the chronic pain and inform the patients of the natural course of various problems causing CLBP. Also, whatever management is chosen, the decision should be based upon the clinical presentation that closely correlates with definitive findings from studies best available whenever possible to provide the best treatment possible, not only to relieve the pain but also to provide functional capability to return previous social status as well as to prevent further development of disability and chronicity with refractory pain syndromes.

In many circumstances, causing sites of low back pain (LBP) cannot be determined only by anatomical imaging. Combined functional and morphological imaging such as bone scan with single-photon emission computed tomography/computed tomography (SPECT/CT) may be helpful in identifying active lesions. The purpose of this study was to evaluate the usefulness of bone SPECT/CT in localizing the pain site and the treatment of chronic LBP. One hundred seventy-five patients suffering from chronic LBP who underwent SPECT/CT were included, retrospectively. All of the patients received multiple general treatments according to the symptoms, and some of them underwent additional target-specific treatment based on SPECT/CT. Numerical rating scale (NRS) pain score was used to assess the pain intensity. Of 175 patients, 127 showed good response to the given therapies, while the rest did not. Overall, 79.4% of patients with definite active lesions showed good response. Patients with mild active or no lesions on SPECT/CT had relatively lower response rate of 63.0%. Good response was observed by the treatment with the guidance of active lesions identified on SPECT/CT. SPECT/CT could be useful in identifying active lesions in patients with chronic LBP and guiding the clinicians to use adequate treatment.

BACKGROUND: Selective lumbar nerve root block (SNRB) is generally accepted as an effective treatment method for back pain with sciatica. However, it requires devices producing radioactive materials such as C-arm fluoroscopy. This study evaluated the usefulness of the longitudinal view of transverse process and needles for medial branch block as landmarks under ultrasonography. METHODS: We performed selective nerve root block for 96 nerve roots in 61 patients under the guidance of ultrasound. A curved probe was used to identify the facet joints and transverse processes. Identifying the lumbar nerve roots under the skin surface and ultrasound landmarks, the cephalad and caudal medial branch blocks were undertaken under the transverse view of sonogram first. A needle for nerve root block was inserted between the two transverse processes under longitudinal view, while estimating the depth with the needle for medial branch block. We then injected 1.0 mL of contrast medium and checked the distribution of the nerve root with C-arm fluoroscopy to evaluate the accuracy. The visual analog scale (VAS) was used to access the clinical results. RESULTS: Seven SNRBs were performed for the L2 nerve root, 15 for L3, 49 for L4, and 25 for L5, respectively. Eighty-six SNRBs (89.5%) showed successful positioning of the needles. We failed in the following cases: 1 case for the L2 nerve root; 2 for L3; 3 for L4; and 4 for L5. The failed needles were positioned at wrong leveled segments in 4 cases and inappropriate place in 6 cases. VAS was improved from 7.6 +/- 0.6 to 3.5 +/- 1.3 after the procedure. CONCLUSIONS: For SNRB in lumbar spine, the transverse processes under longitudinal view as the ultrasound landmark and the needles of medial branch block to the facet joint can be a promising guidance.

Pancreatic inflammatory disease may be classified as acute pancreatitis(AP) and chronic pancreatitis(CP) by primarily clinical criteria, with the obvious difference between them being restoration of normal function in the former and permanent residual damage in the latter. Gallstones and alcohol are the most common causes of acute pancreatitis. Abdominal pain is the major symptom. The diagnosis of AP is usually established by the presence of an increased serum amylase and lipase. CT scanning is the imaging method of choice in determining the severity and complications of AP. There are no generally recognized specific treatments for AP. Supportive therapy, which includes vigorous intravenous hydration, ample analgesia, and vascular, respiratory, and renal support as needed, remains the mainstay of therapy. CP may present as episodes of acute inflammation superimposed on a previously injured pancreas or as chronic fibrotic damage with persistent pain or malabsorption. Alcoholism is the most common cause of CP. The classic triad of pancreatic calcification, steatorrhea, and diabetes mellitus usually establishes the diagnosis of CP. ERCP and pancreatic function test are gold standard imaging procedures for diagnosing CP and planning treatment. Therapy for patients with CP is directed toward major problems such as pain, malabsorption, and diabetes mellitus. Pancreatic enzyme replacement therapy improves the abdominal pain and malabsorption. If Complications is found, endoscopic or Surgical treatments should be considered.

INTRODUCTIONThe use of opioids in chronic non-cancer pain (CNCP) is controversial, as it presents both benefits and risks. There is currently no available data on the incidence, prescription pattern, functional outcomes and adverse effects of opioids in patients with CNCP in Singapore. This study aimed to address the aforementioned deficit.

METHODSAll records of patients who were prescribed strong opioids (for > 3 months per year) for the management of CNCP over a two-year period were retrospectively analysed. Factors including type of opioid, indications for opioid prescription, uncontrolled side effects, functional status, coexisting psychological issues and suspicion of aberrant drug-seeking behaviour were studied.

RESULTSOut of the 1,389 new patients who visited the centre, 42 (3.0%) with CNCP received strong opioids for more than three months a year. The most commonly prescribed opioid was methadone (42.9%). The principal diagnosis for opioid prescription was spinal pain (38.1%). Ten patients had severe side effects. 15 patients saw improvement in activities of daily living scores. Although ten patients returned to work, one stopped following the commencement of opioids. Aberrancy was seen in 5 (11.9%) patients, while 19 (45.2%) had psychological issues and 10 (23.8%) required psychiatric co-management.

CONCLUSIONOpioids are not a panacea for chronic pain. Therefore, functional outcomes should be considered more important end points than mere reductions in pain scores. A multidisciplinary team approach is essential for the effective management of patients with CNCP who are on opioids.
