PURPOSE: Surgical resection of isolated hepatic or pulmonary metastases of colorectal cancer is an established procedure, with a 5-year survival rate of about 50%. However, the role of surgical resections in patients with both hepatic and pulmonary metastases is not well established. We aimed to analyze overall survival of these patients and associated factors. METHODS: Data retrospectively collected from 66 patients who underwent both hepatic and pulmonary metastasectomy after colorectal cancer surgery from August 2002 through August 2013 were analyzed. In univariate analysis, the log-rank test compared patient survival between groups. P < 0.1 was considered indicative of significance. Multivariate analysis of the significance data using a Cox proportional hazard model identified factors associated with overall survival. The synchronous group (n = 57) was defined as patients who had metastasectomy within 3 months from primary colorectal cancer surgery. The remaining nine patients constituted the metachronous group. RESULTS: Median follow-up was 126 months from the primary colorectal cancer surgery. The 5-year survival was 73.4%. There was no difference in overall survival between the synchronous and metachronous groups, consistent with previous studies. Distribution (involving one hemiliver or both, P = 0.010 in multivariate analysis) of liver metastases and multiplicity of the pulmonary metastasis (P = 0.039) were predictors of poor prognosis. CONCLUSION: Sequential or simultaneous resection of both hepatic and pulmonary metastasis of colorectal cancer resulted in good long-term survival in selected patients. Thus, an aggressive surgical approach and multidisciplinary decision making with surgeons seems to be justified.

OBJECTIVE: To evaluate the laboratory and clinical manifestations of Sjögren's syndrome (SS) association with chemokine (C-X-C motif) ligand 1 (CXCL1) expression in the ductal and acinar salivary gland epithelial cells (SGEC) of the minor salivary glands. METHODS: The sociodemographic data of 106 SS patients was obtained, and the glandular and extraglandular manifestations of the disease documented. The minor salivary glands were biopsied and the laboratory findings analyzed. European League Against Rheumatism SS disease activity index (ESSDAI) and SS disease damage index (SSDDI) scores were obtained during biopsy. An immunohistochemical approach was used to define the expression of CXCL1 in the salivary glands. RESULTS: Of 106 patients, the minor salivary glands of 22 patients (20.7%) stained positively for CXCL1. Such CXCL1-positive patients exhibited higher ESSDAI scores at the time of biopsy than the CXCL1-negative patients (3.86±2.27 vs. 2.64±1.62, p=0.015). Lymphadenopathy was more frequently observed in CXCL1-positive patients, compared with CXCL1-negative patients (31.8% vs. 9.5%, p=0.014). No differences between groups were identified in terms of sociodemographic characteristics, laboratory data, or the extent of the glandular manifestation of SS. CONCLUSION: The expression of CXCL1 within the ductal and acinar SGEC of SS patients is associated with lymphadenopathy and elevated clinical disease activity. CXCL1 may play an important role in the disease activity and prognosis of SS.

A 31-year-old man who had been prescribed etanercept over a 3-year period for treatment of ankylosing spondylitis presented with newly developed dry cough, chills, myalgia, and weight loss. Chest computed tomography showed multiple reticulonodular pulmonary infiltrates and bilateral mediastinal, hilar, and peribronchial lymphadenopathy. Biopsy of a paratracheal lymph node revealed chronic granulomatous inflammation without necrosis, and the serum angiotensin-converting enzyme level was elevated. Sarcoidosis was diagnosed. His laboratory and radiological findings, and clinical symptoms improved only after discontinuation of etanercept without treatment. Although etanercept-induced sarcoidosis is rare, this case report suggests that sarcoidosis should be considered in the differential diagnosis of patients treated with the tumor necrosis factor inhibitor.

We investigated the clinical and biological significance of germinal centers (GC) present in the minor salivary glands of patients with Sjogren's syndrome (SS). Minor salivary gland tissue biopsies from 93 patients with SS were used to identify GC-like structures, which were confirmed by CD21-positive follicular dendritic cell networks. Patients were compared based upon sociodemographics, glandular and extraglandular manifestations, and laboratory findings including autoantibody profiles, complement, and immunoglobulin levels; EULAR SS disease activity index (ESSDAI) and SS disease damage index (SSDDI) were also measured. GC-like structures were observed in 28 of 93 SS patients (30.1%). Mean focus scores and CRP levels were significantly higher in GC-positive patients than in GC-negative patients; GC-positive patients also exhibit a higher prevalence of rheumatoid factor and anti-SS-A/Ro antibodies compared to GC-negative patients. No differences in glandular or extra-glandular manifestations were evident between groups. In conclusion, SS patients with GC-like structures in the minor salivary glands exhibited laboratory profiles significantly different from those of their GC-negative counterparts. Long-term follow-up of these patients will be necessary to determine whether these laboratory abnormalities are predictive of clinical outcomes.

Eosinophilic polymyositis is a rare form of inflammatory muscle disease associated with peripheral blood and/or tissue eosinophilia. Most patients respond to glucocorticoids, however some show poor prognosis, leading to mortality. A 28-year-old female was admitted to our hospital because of myalgia and motor weakness of the upper and lower extremities. Laboratory findings showed significantly elevated levels of muscle enzymes and inflammatory lesions in both thigh muscles were demonstrated on magnetic resonance imaging. A diagnosis of eosinophilic polymyositis was based on histological findings, which showed diffuse eosinophilic infiltration into perivascular spaces in the endomysium and perimysium, and necrosis of myofibers. High-dose methylprednisolone treatment improved the clinical symptoms and muscle enzymes. However, on tapering the glucocorticoid dose, clinical and laboratory findings were exacerbated. After the addition of methotrexate and azathioprine, the symptoms and muscle enzymes recovered without relapse. Here, we report on a case of eosinophilic polymyositis, which responded to immunosuppressants.

Fibromyalgia (FM) affects 1% to 5% of the population, and approximately 90% of the affected individuals are women. FM patients experience impaired quality of life and the disorder places a considerable economic burden on the medical care system. With the recognition of FM as a major health problem, many recent studies have evaluated the pathophysiology of FM. Although the etiology of FM remains unknown, it is thought to involve some combination of genetic susceptibility and environmental exposure that triggers further alterations in gene expression. Because FM shows marked familial aggregation, most previous research has focused on genetic predisposition to FM and has revealed associations between genetic factors and the development of FM, including specific gene polymorphisms involved in the serotonergic, dopaminergic, and catecholaminergic pathways. The aim of this review was to discuss the current evidence regarding genetic factors that may play a role in the development and symptom severity of FM.

Neuropsychiatric manifestations in patients with systemic lupus erythematosus are fairly common, with a prevalence of 37~95%. Among 19 neuropsychiatric manifestations, acute inflammatory demyelinating polyradiculoneuropathy (AIDP) is quite rare, and is characterized by progressive, symmetric muscle weakness accompanied by absent or depressed deep tendon reflexes. Generally, plasma exchange and intravenous immunoglobulin are the main treatment modalities. Here, we report a case of AIDP in a 29-year-old SLE patient, who was fully recovered with a treatment of high-dose glucocorticoid and immunosuppressive agents. Ours case suggests that AIDP should be treated differently in SLE patients to avoid disastrous results.

We investigated the compliance of Korean patients using tumor necrosis factor (TNF) inhibitors to treat rheumatoid arthritis (RA) and ankylosing spondylitis (AS), and identified potential predictors associated with treatment discontinuation. The study population comprised 114 RA and 310 AS patients treated with TNF inhibitors at a single tertiary center for at least 1 yr from December 2002 to November 2011. Of the 114 RA patients, 64 (56.1%) discontinued their first TNF inhibitors with a mean duration of 18.1 months. By contrast, 65 of 310 patients (21.0%) with AS discontinued their first TNF inhibitors, with a mean duration of 84 months. Although the survival rate did not differ among the three TNF inhibitors in the AS patients, the etanercept group had a lower discontinuation rate than the infliximab group in the RA patients. In addition, RA patients who received corticosteroids in combination with TNF inhibitors were more likely to discontinue their TNF inhibitors. The independent predictors of drug discontinuation in AS patients were male gender and complete ankylosis on radiographs of the sacroiliac joint. Our results provide further evidence that real-life treatment outcomes of RA and AS patients may be different from those observed in randomized clinical trials.
