Chronic rhinitis and stress: the possible culprits of midfacial segment pain.

BACKGROUND: Bilateral symmetrical pain in the midfacial region without evidence of sinonasal disease is termed midfacial segment pain (MSP), about which little is known. The present study explored the prevalence of facial pain and the risk factors for MSP. METHODS: We analysed cross-sectional data from the Korea National Health and Nutrition Examination Survey (KNHANES). Those who reported facial pain or pressure lasting at least three months with no evidence of a sinonasal disease on nasal endoscopy were considered to have MSP. The participants were categorised according to the presence of facial pain and chronic rhinosinusitis. Basic demographic data and medical conditions, including hypertension, diabetes mellitus, and dyslipidemia, were compared between subject groups. We also evaluated psychological stress, depressive episodes, and suicidal thoughts, as well as physician-diagnosed nasal diseases, including chronic rhinitis and symptomatic nasal septal deviation. Univariate and multivariate logistic regression analyses were performed to determine risk factors for MSP. RESULTS: Of 31,999 participants, the prevalence of facial pain was 0.59%. A total of 58 (0.18%) respondents had MSP, of whom 40 (73.5%) were female. On univariate analysis, female sex, chronic rhinitis, and psychological stress were more prevalent in the subjects with MSP than the control subjects. However, in the multivariate analysis, only chronic rhinitis and psychological stress remained significant, while the female sex exhibited only marginal significance. CONCLUSION: Chronic rhinitis and psychological stress may be significant risk factors for MSP.

Clinical characteristics and associated factors of qualitative olfactory dysfunction.

BACKGROUND: Although interest in qualitative olfactory dysfunction (OD), including parosmia and phantosmia, has been increasing since the COVID-19 pandemic, little is known about the clinical characteristics and associated factors of qualitative OD. METHODS: Adult patients with subjective smell disturbance who underwent both the olfactory questionnaire and psychophysical olfactory function test were retrospectively enrolled. Demographic and clinical characteristics were analysed according to the presence or absence of parosmia or phantosmia. RESULTS: Among a total of 753 patients with self-reported OD, 60 (8%) and 167 (22.2%) patients reported parosmia and phantosmia, respectively. Younger age and female sex were related to both parosmia and phantosmia. The frequency of parosmia was significantly higher in patients with post-viral OD (17.9%) than in patients with the sinonasal disease (5.5%), whereas that of phantosmia was not different according to aetiologies of OD. Patients with COVID-19 had significantly younger ages and higher TDI scores than those with other viral infections. Remarkably, patients with parosmia or phantosmia had significantly higher TDI scores than those without but experienced more disruption in daily life. In the multivariate analysis, younger age and higher TDI score were identified as independent factors associated with both parosmia and phantosmia, while the viral infection was associated with parosmia but not with phantosmia. CONCLUSIONS: Patients with OD who have parosmia or phantosmia have higher odour sensitivity than those who do not, but experience more deterioration in the quality of life. Viral infection is a risk factor for parosmia but not for phantosmia.

Association between the use of electronic cigarettes and the prevalence of chronic rhinosinusitis and allergic rhinitis: a nationwide cross-sectional study.

BACKGROUND: Whether the use of electronic cigarettes (ECs) is associated with upper airway diseases, including chronic rhinosinusitis (CRS) and allergic rhinitis (AR), remains unclear. METHODS: We analyzed data from the nationwide cross-sectional surveys: the Korea National Health and Nutrition Examination Survey VI (2013-2015), VII (2016-2018), and VIII (2019). Logistic regression analysis was performed to assess the association between EC use and CRS or AR. RESULTS: Among a total of 38,413 participants, 6.4% were former EC users and 2.5% were current EC users. Former EC users and current EC showed a significantly increased OR for CRS or AR compared with never EC users. In the subgroup analysis, the "current CC (conventional cigarette)-current EC" and the "current CC-formal EC" group had a significantly higher OR for CRS or AR than the "current CC-never EC" group. In addition, former CC smokers who currently use ECs showed a significantly higher OR for AR than former CC smokers without EC use. CONCLUSIONS: EC use is significantly associated with a high prevalence of CRS and AR in the adult population. These results indicate that the use of ECs may increase the risk of upper airway disease.

Association of the human papillomavirus infection with the recurrence of sinonasal inverted papilloma: a systematic review and meta-analysis.

BACKGROUND: Although the role of human papillomavirus (HPV) in sinonasal inverted papilloma (SNIP) has been investigated, the link between HPV infection and SNIP recurrence remains controversial. This meta-analysis aimed to investigate the association between HPV infection and recurrence of SNIP. METHODS: The PubMed, Web of Science, Google Scholar, and Cochrane Library databases were searched (until 16 June 2021) to collect all relevant articles. The pooled odds ratio (OR) with 95% confidence interval (CI) was calculated using the fixed effects model. In addition, subgroup analysis, assessment of publication bias, and sensitivity analyses were performed. RESULTS: Fourteen eligible articles, including 592 patients with SNIP, were included in this study. Pooled analysis revealed that HPV-positive cases exhibited a significantly higher OR of tumour recurrence than HPV-negative counterparts). A significant association between HPV infection and tumour recurrence remained stable in subgroup analyses according to the publication year of the studies. CONCLUSIONS: Our meta-analysis demonstrates that HPV infection is significantly associated with the recurrence of SNIP, suggesting the pathological role of HPV in SNIP. These results suggest that HPV infection should be considered in the management of SNIP.

Gustatory dysfunction in patients with olfactory dysfunction and the associated factors.

BACKGROUND: Little is known about the occurrence of gustatory dysfunction (GD) in relation to different aetiologies of olfactory dysfunction (OD) as assessed by psychophysical chemosensory tests. The aim of this study was to analyse gustatory function in patients with OD and to investigate clinical factors associated with GD. METHODS: A total of 742 individuals who underwent both olfactory and gustatory function tests at a tertiary medical centre from November 2019 to March 2021 were retrospectively enrolled. Olfactory and gustatory function were assessed by the YSK olfactory and gustatory function tests, respectively. Patients with OD were classified into four groups according to the aetiology: sinonasal disease, post-infection OD (PIOD), post-traumatic OD (PTOD), and others. Secondary outcomes included age, sex, smoking history, and alcohol history. RESULTS: Among the 488 patients with OD, 93 (19.1%) showed GD and 395 (80.9%) had normal gustatory function. Only 25 (9.8%) among 254 individuals with normosmia showed GD. Analyses of these frequencies revealed a significant association between OD and GD. In addition, the taste score was significantly lower in patients with OD than individuals with normosmia. The frequency of GD was significantly higher in patients with PTOD (53.6%) than in those with OD of other aetiologies (sinonasal disease, 6.7%; PIOD, 13.0%; others, 24.4%). In the multivariate analysis, age >=5 years and PTOD were associated with a high frequency of GD among patients with OD. CONCLUSIONS: The current study show that GD is significantly associated with OD. In particular, GD is more common in patients with PTOD than in those with OD of other aetiologies.

Increased risk of cardiovascular diseases in patients with chronic rhinosinusitis: a longitudinal follow-up study using a national health screening cohort.

BACKGROUND: Chronic rhinosinusitis (CRS) is one of the most common chronic inflammatory diseases and is characterized by sinonasal inflammation that lasts longer than 12 weeks. Whether the effect of chronic inflammation caused by CRS on cardiovascular diseases (CVDs) is similar to its effect on other inflammatory disorders has not been thoroughly evaluated. We aimed to demonstrate whether CRS patients have a higher prevalence of CVDs, including stroke and ischemic heart disease (IHD). METHODOLOGY: We compared the prevalence of various comorbidities between CRS and control participants through a case-control cohort study from 2002 to 2015 that included 514,866 participants. CRS (n=6,552) and control (n=26,208) participants who were over 40 years old were selected by matching age, sex, income, and area of residence at a 1:4 ratio. RESULTS: A stratified Cox proportional hazards model was utilized to assess the hazard ratio (HR) of CRS for stroke and IHD. The HRs for stroke and IHD were significantly increased in CRS patients compared to controls after adjusting for obesity, alcohol consumption, smoking, systolic and diastolic blood pressure, fasting blood glucose, total cholesterol, hemoglobin, and Charlson Comorbidity Index (CCI) scores. The HR of stroke was significantly higher in the absence of nasal polyps than in the presence of nasal polyps. The HR of IHD was significantly increased in the CRS group regardless of the presence of nasal polyps. CONCLUSIONS: This study showed that CRS participants had a significantly higher prevalence of stroke and IHD.

Differences and similarities between the upper and lower airway: focusing on innate immunity.

The nose is the first respiratory barrier to external pathogens, allergens, pollutants, or cigarette smoke, and vigorous immune responses are triggered when external pathogens come in contact with the nasal epithelium. The mucosal epithelial cells of the nose are essential to the innate immune response against external pathogens and transmit signals that modulate the adaptive immune response. The upper and lower airways share many physiological and immunological features, but there are also numerous differences. It is crucial to understand these differences and their contribution to pathophysiology in order to optimize treatments for inflammatory diseases of the respiratory tract. This review summarizes important differences in the embryological development, histological features, microbiota, immune responses, and cellular subtypes of mucosal epithelial cells of the nose and lungs.

Compressive stress induces collective migration through cytoskeletal remodelling in nasal polyp epithelium.

BACKGROUND: Nasal polyps in the nasal cavity and mucous discharge inside the maxillary sinus exhibit compressive stress on the nasal mucosal epithelium. However, there have been only a few studies on how compressive stress impacts the human nasal mucosal epithelium. METHODOLOGY: We investigated the effect of compressive stress on collective migration, junctional proteins, transepithelial electri- cal resistance, epithelial permeability, and gene expression in well-differentiated normal human nasal epithelial (NHNE) cells and human nasal polyp epithelial (HNPE) cells. RESULTS: NHNE cells barely showed collective migration at compressive stress up to 150 mmH20. However, HNPE cells showed much greater degree of collective migration at a lower compressive stress of 100 mmH20. The cell migration of HNPE cells sub- jected to 100 mmH2O compression was significantly decreased at day 3 and was recovered to the status prior to the compressive stress by day 7, indicating that HNPE cells are relatively more sensitive to mechanical pressure than NHNE cells. Compressive stress also increased transepithelial electrical resistance and decreased epithelial permeability, indicating that the compressive stress disturbed the structural organization rather than physical interactions between cells. In addition, we found that compressive stress induced gene expressions relevant to airway inflammation and tissue remodelling in HNPE cells. CONCLUSION: Taken together, these findings demonstrate that compressive stress on nasal polyp epithelium is capable of inducing collective migration and induce increased expression of genes related to airway inflammation, innate immunity, and polyp remo- delling, even in the absence of inflammatory mediators.

Association between body mass index and stroke severity in acute ischaemic stroke with non-valvular atrial fibrillation.

BACKGROUND AND PURPOSE: The objective of this study was to investigate the association between body mass index (BMI) and both initial stroke severity at presentation and functional outcomes after acute ischaemic stroke (AIS) in patients with non-valvular atrial fibrillation (NVAF). METHODS: Patients were categorized on the basis of their BMI into underweight (BMI <18.5, n = 111), normal (18.5 ≤ BMI <25, n = 1036) and overweight to obese (BMI ≥25, n = 472) groups. Initial stroke severity was assessed using the National Institutes of Health Stroke Scale (NIHSS) score and functional outcomes were assessed using the modified Rankin Scale score at discharge. The differences in stroke severity and functional outcomes were compared between groups using robust log-linear regression with a Poisson distribution and binary logistic regression analysis. RESULTS: A total of 1619 AIS patients with NVAF from six hospitals were included. Compared with the NIHSS scores [median 5, interquartile range (IQR) 2-14] of normal-weight patients, the NIHSS scores (median 9, IQR 4-19) of underweight patients were more likely to be higher, whereas those of overweight to obese patients were lower (median 4, IQR 1-12) (P < 0.001). In terms of functional outcomes after stroke, underweight patients had a higher risk of poor functional outcomes (odds ratio 1.78, 95% confidence interval 1.09-2.56, P = 0.01) but overweight to obese patients had no significant difference in functional outcomes compared with normal-weight patients. CONCLUSION: An inverse association was found between BMI and stroke severity in AIS patients with NVAF. This suggests the presence of an obesity paradox for short-term outcomes in patients with NVAF.

Different functional genes of upper airway microbiome associated with natural course of childhood asthma.

BACKGROUND: Microbial colonization of the airway plays a role in the pathogenesis of asthma; however, the effect of the upper airway microbiome on childhood asthma is not fully understood. We analyzed the metagenome of airway microbiome to understand the associated role of upper airway microbiome with the natural course of childhood asthma. METHODS: Nasopharyngeal swabs were collected from children with asthma, those in asthma remission, and control groups. High-throughput sequencing was used to examine the structure and functional dynamics of the airway microbiome with respect to asthma phenotypes. RESULTS: The composition of microbiota differed among healthy control, asthma, and remission groups. The relative abundance of Streptococcus was negatively associated with FEV1% predicted (P = .023) and that of Staphylococcus was negatively associated with methacholine PC20 (P = .013). Genes related to arachidonic acid metabolites, lysine residues, and glycosaminoglycans in the microbiome could be associated with airway inflammation. In particular, genes related to synthesis of anti-inflammatory prostaglandin E2 (PGE2 ) were not detected from the airway microbiome in the asthma group. CONCLUSIONS: These data suggest that alterations in the composition and function of the upper airway microbiome could be related with the natural course of asthma in children.

Comparison of robotic and coblation tongue base resection for obstructive sleep apnoea.

OBJECTIVES: To compare the efficacy and safety of transoral robotic surgery (TORS) with endoscope-guided coblation tongue base resection. DESIGN: Retrospective case-control study. SETTING: University-based tertiary care medical center. PARTICIPANTS: Patients with obstructive sleep apnoea (OSA) who underwent endoscope-guided tongue base coblation resection or transoral robotic surgery (TORS) in combination with lateral pharyngoplasty at a single institution in South Korea between April 2013 and December 2016 were investigated. Forty-five patients who had moderate-to-severe OSA with tongue base collapse and a minimum follow-up period of 6 months with postoperative polysomnography (PSG) were enrolled in this study. MAIN OUTCOME MEASURES: All patients underwent pre- and postoperative (at least 4 months after surgery) overnight PSG. Available information on results of the PSG, Epworth sleepiness scale and complications of the TORS and coblation groups were compared. RESULTS: Postoperative PSG studies showed improved sleep quality for most patients. The mean postoperative apnoea-hypopnea index (AHI) was reduced significantly from 45.0 to 17.0 events/h (P < .0001) in the TORS group and from 45.6 to 16.2 events/h (P < .0001) in the coblation group. The mean rates of improvement (AHI reduction > 50%) were 75.0% in TORS patients and 62.1% in coblation patients and the difference was not significant. Less frequent postoperative morbidity, including bleeding, taste dysfunction and foreign body sensation, was recorded in TORS patients. CONCLUSIONS: Both the coblation and TORS groups showed similar surgical outcomes, TORS achieved PSG results non-inferior to and complication rates comparable to coblation.

Atopic dermatitis phenotype with early onset and high serum IL-13 is linked to the new development of bronchial hyperresponsiveness in school children.

BACKGROUND: Atopic dermatitis (AD) is characterized by a heterogeneous clinical spectrum, and some forms of AD are associated with the initial steps of allergic march. The aims of this study were to determine AD phenotypes in school-age children and investigate their associations with the allergic march in each cluster. METHODS: We included 242 children (6-8 years) with current AD from the Children's HEalth and Environmental Research study, a 4-year prospective follow-up study with 2-year survey intervals. Latent class analysis was used. Serum IL-13 and thymic stromal lymphopoietin (TSLP) levels at the time of enrollment were measured using ELISA. RESULTS: We identified four current AD phenotypes in children, characterized as 'early onset with low atopy' (26.4% of the sample; group 1), 'early onset with high atopy and high eosinophil percentages' (48.3%; group 2), 'late onset with low atopy' (9.9%; group 3), and 'late onset with high atopy and normal eosinophils' (15.3%; group 4). Although groups 2 and 4 demonstrated high atopic burden, children in group 2 showed the persistence of AD and eosinophilia associated with a high prevalence of new cases of bronchial hyper-responsiveness and asthma symptoms during follow-up. The serum IL-13 level was significantly increased in the early-onset AD groups, but there was no significant difference in the serum TSLP levels across all four groups. CONCLUSION: An allergic march-associated AD phenotype exists that is characterized by early onset of AD with its persistence, increased serum IL-13 levels, high atopy, and a persistently increased blood eosinophil percentage.

Pure non-gestational choriocarcinoma arising in the ovary.

Non-gestational choriocarcinoma (NGCO) is a rare primary ovarian cancer with poor prognosis. It is important to distinguish it from gestational ovarian choriocarcinoma (GCO), because there are different treatment options. However, it is difficult to distinguish the two types by routine histologic, ultrastructural, or immunohistochemical examination. The authors present NGCO in a 41-year-old woman, which was confirmed by DNA polymorphism analysis. All tested microsatellite markers had identical DNA profiles with the same allelic sizes between tumor and normal myometrium of the patient, indicating that both tissues originated from the same person. The results confirmed that the tumor was non-gestational in origin. Although the tumor was large, the authors performed hand- assisted laparoscopic surgical (HALS) staging. After three cycles of combination chemotherapy and surgery, the patient has not had any evidence of disease 48 months after treatment. This case demonstrates the usefulness of HALS staging and DNA polymorphism analysis in NGCO.

Clinical implications of serum galactomannan measurement in patients with acute invasive fungal rhinosinusitis.

BACKGROUND: Acute invasive fungal rhinosinusitis (AIFR) is an aggressive opportunistic infection with a high mortality rate. Recently, non-invasive techniques have been introduced for diagnosis of invasive fungal disease. The purpose of this study is to evaluate the diagnostic significance of serum galactomannan measurement in patients with AIFR. METHODOLOGY: We conducted a retrospective case-control study of 28 patients with AIFR and 36 fungus ball (FB) patients. We evaluated clinical, laboratory, and pathologic findings along with disease course. RESULTS: In 28 patients with AIFR, there were 21 cases of invasive aspergillosis (IA) and 7 cases of invasive mucormycosis (IM). The control group was comprised of 36 patients with FB. The three-group analysis showed a statistically significant difference among the groups. At the cut-off value of 0.48, the sensitivity and specificity were 71.4% and 93.0%, respectively. Comparison of mean serum galactomannan levels in 5 non-survivors and 9 survivors at initial measurement showed no significant difference, but that became significantly different 1 week later. Statistical analysis showed that the levels of serum galactomannan decreased significantly according to the measurement-point in within survivor-group analysis. The difference in between survivor-groups analysis was also significant. CONCLUSION: Serum galactomannan measurement seems useful for early diagnosis and discrimination of fungal species in patients with AIFR. In addition, clinical outcomes may be related to the levels and patterns of serum galactomannan, especially in IA. The appropriate measurement of galactomannan might be helpful in treating the patients at high risk for AIFR.

Differential characteristics of pediatric sinusitis in patients who underwent endoscopic sinus surgery: children vs. adolescents.

OBJECTIVES: We hypothesised that paediatric chronic sinusitis patients might have various clinical characteristics, depending on age, compared symptoms, physical findings and clinical features in younger children and older adolescent patients who underwent endoscopic sinus surgery. DESIGN: A retrospective review of medical records. SETTING: A total of 195 paediatric patients who underwent Endoscopic sinus surgery were enrolled and medical records were reviewed. PARTICIPANTS: The subjects were divided into children (age < 12 years, n = 70, mean age = 9.6 years) and adolescents (age ≥ 12 years, n = 125, mean age = 14.7 years). MAIN OUTCOME MEASURES: Subjective symptoms, physical findings, CT images and clinical features were compared in children and adolescent groups. RESULTS: Cough and nasal obstruction were more common in adolescents, and sleep disturbance was more common in children. Nasal mucosal injection was more common in adolescents, whereas tonsils were larger in children. Septal deviation was a more common finding in adolescents, and total CT score and serum total IgE levels were higher in children. There was no statistical difference in rate of recurrence after endoscopic sinus surgery. CONCLUSION: The clinical features of paediatric chronic sinusitis differed between the younger and older groups. Symptomatic, anatomical and clinical differences between these two groups suggest that further study of paediatric chronic sinusitis should stratify patients by age to better understand the effects of treatment on each age group.

Concomitant ALK translocation and EGFR mutation in lung cancer: a comparison of direct sequencing and sensitive assays and the impact on responsiveness to tyrosine kinase inhibitor.

BACKGROUND: Epidermal growth factor receptor (EGFR) mutation and anaplastic lymphoma kinase (ALK) translocation are considered mutually exclusive in nonsmall-cell lung cancer (NSCLC). However, sporadic cases having concomitant EGFR and ALK alterations have been reported. The present study aimed to assess the prevalence of NSCLCs with concomitant EGFR and ALK alterations using mutation detection methods with different sensitivity and to propose an effective diagnostic and therapeutic strategy. PATIENTS AND METHODS: A total of 1458 cases of lung cancer were screened for EGFR and ALK alterations by direct sequencing and flourescence in situ hybridization (FISH), respectively. For the 91 patients identified as having an ALK translocation, peptide nucleic acid (PNA)-clamping real-time PCR, targeted next-generation sequencing (NGS), and mutant-enriched NGS assays were carried out to detect EGFR mutation. RESULTS: EGFR mutations and ALK translocations were observed in 42.4% (612/1445) and 6.3% (91/1445) of NSCLCs by direct sequencing and FISH, respectively. Concomitant EGFR and ALK alterations were detected in four cases, which accounted for 4.4% (4/91) of ALK-translocated NSCLCs. Additional analyses for EGFR using PNA real-time PCR and ultra-deep sequencing by NGS, mutant-enriched NGS increased the detection rate of concomitant EGFR and ALK alterations to 8.8% (8/91), 12.1% (11/91), and 15.4% (14/91) of ALK-translocated NSCLCs, respectively. Of the 14 patients, 3 who were treated with gefitinib showed poor response to gefitinib with stable disease in one and progressive disease in two patients. However, eight patients who received ALK inhibitor (crizotinib or ceritinib) showed good response, with response rate of 87.5% (7/8 with partial response) and durable progression-free survival. CONCLUSIONS: A portion of NSCLC patients have concomitant EGFR and ALK alterations and the frequency of co-alteration detection increases when sensitive detection methods for EGFR mutation are applied. ALK inhibitors appear to be effective for patients with co-alterations.

Ascites associated with uterine leiomyoma in a 22-year-old woman with systemic lupus erythematosus.

Ascites in systemic lupus erythematosus (SLE) patients has a variety of etiologies, which usually require different treatment options. Our case was a 22-year-old patient with an unusual combination of ascites, uterine leiomyoma and SLE. The patient presented with painless ascites of an inflammatory nature. However, the ascites was not related to peritonitis and SLE disease activity. The ascites disappeared following laparotomy and tumor resection without additional medication. Gynecologic benign tumors including uterine leiomyoma can be the cause of ascites in SLE patients. Clinicians should be aware of that possibility in case painless ascites occurs in females with SLE.

The association of radiographic progression with serum R-spondin 1 (RSPO1) levels or Dickkopf-1 (DKK1)/RSPO1 ratios in rheumatoid arthritis patients: clinical evidence for reciprocal inhibition between DKK1 and RSPO1.

OBJECTIVES: To investigate the clinical implications of serum levels of R-spondin 1 (RSPO1), a natural antagonist for Dickkopf-1 (DKK1), and of DKK1/RSPO1 ratios in rheumatoid arthritis (RA) patients. METHOD: Serum DKK1 and RSPO1 levels were measured in 102 RA patients and 39 age- and gender-matched healthy controls. In addition, DKK1 and RSPO1 levels were determined prior to and 3 months after anti-tumour necrosis factor alpha (anti-TNF-α) therapy in 15 RA patients. Clinical and laboratory data and baseline radiographs of the hands and feet were obtained. Serial radiographs were evaluated in 83 RA patients. Radiographic joint damage was assessed by the modified Sharp/van der Heijde score (SHS). RESULTS: Serum RSPO1 levels were significantly reduced whereas serum DKK1 levels and DKK1/RSPO1 ratios were significantly increased in RA patients compared with controls (all p < 0.0001). Anti-TNF-α treatment significantly suppressed DKK1/RSPO1 ratios (p < 0.01). In contrast to DKK1 or RSPO1 levels, the ratios were significantly associated with erosive disease, elevated acute phase reactants, Disease Activity Score in 28 joints (DAS28) > 3.2, and radiographic progression rate (all p < 0.05). Although the RA patients with radiographic progression exhibited significantly increased DKK1 and reduced RSPO1 levels (p < 0.05), only the DKK1/RSPO1 ratio (log-transformed) was found to be a significant predictor of subsequent radiographic progression [odds ratio (OR) 2.07, p < 0.01]. CONCLUSIONS: In this study, the presence of RSPO1 in the circulation was shown for the first time. Our results suggest that the serum DKK1/RSPO1 ratio represents a better predictor of structural progression than either DKK1 or RSPO1 levels alone in RA patients.

Comparison of alfuzosin 10 mg with or without propiverine 10 mg, 20 mg in men with lower urinary tract symptom and an overactive bladder: randomised, single-blind, prospective study.

PURPOSE: The efficacy and safety of treatment with alfuzosin 10 mg plus propiverine 10 or 20 mg in men with lower urinary tract symptoms (LUTS) and an overactive bladder were investigated. MATERIALS AND METHODS: In this parallel-arm, prospective, multicentre, single-blind study, men who were ≥ 40 years old, had an International Prostate Symptom Score (IPSS) of ≥ 8, an Overactive Bladder Symptom Score (OABSS) of ≥ 3 and an OABSS urgency item score of ≥ 2 were randomised in a 1 : 1 :1 ratio to receive alfuzosin 10 mg alone (Group A) or with propiverine 10 mg (Group B) or 20 mg (Group C) for 8 weeks. Four and 8 weeks after commencing treatment, OABSS was measured along with IPSS, maximal urinary flow rate (Qmax ) and postvoid residual volume (PVR). Adverse events were recorded. RESULTS: A total of 135 men, including 43 in Group A, 48 in Group B and 44 in Group C, completed the study. Relative to baseline, all groups demonstrated significant reductions in OABSS and the IPSS after eight treatment weeks (p < 0.005). The improvement of OABSS in Group C was significantly greater than Group A and B (Group A: 0.70 ± 1.94; Group B: 2.50 ± 2.98; Group C: 4.30 ± 3.40; p < 0.005). An observed improvement of Qmax and PVR in the three groups did not achieve statistical significance. Overall adverse event rates were higher in Group C but not significant compared with others. CONCLUSION: In patients with LUTS and overactive bladder, combined therapy with alfuzosin 10 mg plus propiverine 20 mg was significantly more effective than alfuzosin monotherapy and propiverine 10 mg combined therapy in terms of improving OABSS while not significantly affecting Qmax or PVR.

Meigs' syndrome with elevated serum CA 125 level in a case of ovarian fibrothecoma.

Meigs' syndrome is the association of benign ovarian tumor, pleural effusion, and ascites. Meigs' syndrome with marked elevated CA 125 is a rare clinical entity and only 42 cases have been reported. Although there is difficulty in discerning the diagnosis of Meigs' syndrome from that of an ovarian malignancy, it should be considered in the differential diagnosis in postmenopausal patients with an ovarian mass, hydrothorax, ascites, and elevated CA 125. In this report, the authors present the case of a 52-year-old postmenopausal woman with ovarian fibrothecoma, pleural effusion, ascites, and elevated CA 125 (319.2 IU/ml). Exploratory laparotomy with total hysterectomy and bilateral salpingo-oophorectomy was performed, and the pathologic diagnosis was ovarian fibrothecoma. After the surgery, the pleural effusion disappeared spontaneously and the CA 125 became normal. The authors also summarized other cases of Meigs' syndrome with elevated CA 125, and reviewed the mechanism of elevation of CA 125, ascites, and pleural effusion.
