RESUMEN
Yellow nail syndrome (YNS) can induce bilateral exudative pleural effusion; however, to the best of our knowledge, no standard treatment for YNS has been established. The present study describes a patient with YNS for whom the pleural effusion was controlled by prednisolone. A 73-year-old man was referred to the University of Tsukuba Hospital (Ibaraki, Japan) complaining of shortness of breath, which was diagnosed as being due to bilateral pleural effusion. Based on the presence of yellowing and growth retardation of the toenails, lymphedema, bilateral exudative pleural fluid of unknown etiology, and lymphatic congestion on lymphoscintigraphy, the patient was diagnosed with YNS. The pleural fluid was predominantly lymphocytic and responded to systemic steroid administration [prednisolone 30 mg/day (0.5 mg/kg) for 2 weeks, with subsequent weekly tapering]. The general condition of the patient and their dyspnea also improved with treatment. These findings indicated that systemic steroid administration should be considered as one of the treatment options for patients with YNS who are reluctant to undergo chest drainage or pleurodesis due to the potential for a decrease in their ability to perform daily activities and respiratory function.
RESUMEN
BACKGROUND/AIM: The association between resected non-small cell lung cancer (NSCLC) and long-term outcomes of muscle mass depletion and muscle weakness has also not been well documented. This study evaluated whether muscle mass depletion assessed by bioelectrical impedance analysis (BIA) and low muscle strength assessed by the peak expiratory flow rate as a percentage of predicted value (%PEFR) were associated with surgical outcomes in patients with resected NSCLC. PATIENTS AND METHODS: This retrospective study included 219 patients with resected NSCLC between 2016 and 2021. The cutoff value for muscle mass depletion was according to guidelines, for low muscle strength, we defined by receiver operating characteristics analysis for recurrence-free survival (RFS). Survival analysis was performed, and postoperative outcomes were compared. RESULTS: A total of 76 patients (34.7%) had muscle mass depletion, and 114 patients (52.1%) had low muscle strength. Muscle mass depletion and low muscle strength were independent poor prognostic factors for overall survival [hazard ratio (HR)=2.631, p=0.003; HR=1.983, p=0.044] and RFS (HR=3.120, p<0.001; HR=1.857, p=0.028) in multivariate analysis. Postoperative complication was associated with low muscle strength (p=0.009). Postoperative recurrence was associated with muscle mass depletion (p=0.03). CONCLUSION: Preoperative muscle mass depletion assessed by BIA and low muscle strength determined by %PEFR are worse prognostic factors after surgical resection for NSCLC. Our results may provide some important information for preoperative management.

BACKGROUND: The use of an endoscopic position detection unit (UPD) enables better and more objective understanding of the shape and position of the colonoscope. Here, we investigated the reproducibility of the insertion of a colonoscope with UPD. MATERIALS AND METHODS: Study participants were 122 patients who received a colonoscopy with UPD twice for the purpose of large bowel screening and surveillance. The mean age of participants was 69.7 ± 10.4 years, and the male-to-female ratio was 9.2:1. The colonoscope insertion technique was primarily based on the shaft-holding, shortening insertion method. The cecal intubation time was recorded; the method used for passing through the sigmoid/descending colon junction (SDJ) and the hepatic flexure. RESULTS: The mean cecal intubation time was 990 ± 511 s. The cecal intubation time and the patterns for passing through the SDJ and hepatic flexure were significantly correlated between the first and second colonoscopies. CONCLUSION: Use of a UPD revealed good reproducibility of colonoscope insertion. This is the first time we have proved that both time and pattern are inserted in much the same way for the first and second times. In patients' conducted UPD combination TCS after the second time, it was suggested that individual tailor-made insertions are possible based on the information from the first time.
RESUMEN
Endoscopic population-based screening for gastric cancer began in April 2016, and the use of transnasal ultrathin esophagogastroduodenoscopy (UT-EGD) has rapidly become popular. With UT-EGD, discomfort associated with an examination is reduced, patient satisfaction is high, and adverse effects on cardiopulmonary function are fewer. Consequently, UT-EGD is a good option for gastric screening in an aging society. Because of the narrower diameter of the endoscope, however, image quality is inferior to that obtained using transoral conventional esophagogastroduodenoscopy (C-EGD). As a result, lesions observed by UT-EGD must be viewed at close proximity and chromoendoscopy should be used concurrently, which is burdensome for the endoscopist. Recent innovations by endoscope manufacturers have enabled dramatic improvements in transnasal UT-EGD and facilitated Hi-Vision imaging. Furthermore, image enhancement that allows for observation on a par with transoral C-EGD is now feasible. In the future, UT-EGD will be equipped with functions that permit magnified endoscopic image. It is anticipated that a multiroute transition between transnasal and transoral UT-EGD will become possible.

Introduction: Ovarian granulosa cell tumor is a relatively rare tumor that accounts for 2-5% of malignant ovarian tumors. This tumor progresses slowly and may recur late in life. Case presentation: A 70-year-old woman was admitted to our hospital with a left secondary pneumothorax due to metastatic lung tumors of granulosa cell tumor. Reports of secondary pneumothorax due to granulosa cell tumor are rare. Thoracoscopic suturing and pleurodesis using talc were effective in the treatment of this pneumothorax. Conclusions: We experienced a rare case of secondary pneumothorax due to multiple pulmonary metastases of granulosa cell tumor. It should be noted that pulmonary metastasis of granulosa cell tumor can lead to secondary pneumothorax.
RESUMEN
BACKGROUND/AIMS: To evaluate the axial length (AL) and refractive status in central serous chorioretinopathy (CSC). METHODS: This retrospective observational case series involved 140 patients with CSC (180 eyes) and 78 age-matched and gender-matched control subjects. A detailed ophthalmic examination was performed, including an interferometer measurement of AL. Multimodal imaging comprised colour fundus photography, fluorescein angiography, indocyanine green angiography, fundus autofluorescence photography and spectral domain optical coherence tomography. RESULTS: Eighty eyes of 40 patients were categorised into the bilateral-CSC (b-CSC) group and 100 eyes of 100 patients were categorised into the unilateral-CSC (u-CSC) group. AL of the b-CSC (23.19 mm) and u-CSC (23.75 mm) groups was significantly shorter than that of the control (24.85 mm) group (p<0.001 for both). Moreover, AL was significantly shorter in the b-CSC group than in the u-CSC group (p=0.020). Spherical equivalent (SE) in the b-CSC (0.25 D) group was significantly greater than in the u-CSC (-0.81 D) and control (-1.38 D) groups (p<0.001 for both). Gender (male; OR 4.55; 95% CI 1.13 to 18.40; p=0.033), AL (OR 0.38; 95% CI 0.23 to 0.63; p<0.001), area of choroidal vascular hyperpermeability (OR 1.08; 95% CI 1.03 to 1.13; p=0.002) and presence of descending tract (OR 7.22; 95% CI 1.86 to 28.00; p=0.004) were the variables found to be significantly associated with b-CSC via multiple regression analyses. CONCLUSION: Anatomical features, such as shorter AL and greater SE, may be associated with the pathogenesis of CSC.

Lung cancer is a major health concern worldwide, but new immunotherapeutic treatments for lung cancer have shown great promise and the prognosis for many severe cancers including lung cancer has been improving. In May 2017, the Food and Drug Administration approved pembrolizumab, a therapeutic antibody that blocks lymphocytic programmed death-1 (PD-1), as a first-line treatment for any solid tumor with specific genetic features. Pembrolizumab is a therapeutic antibody that blocks lymphocytic PD-1, the ligand of which (PD-L1) is expressed on tumor cells and which can prevent the immune system from recognizing and destroying tumors. Here, we report two cases of double cancer (case 1: lung and bladder cancer; case 2: gastric and lung cancer) in which pembrolizumab was effective for the treatment of both cancers in each patient.

Purpose: To clarify the distinct molecular pathogenesis of central serous chorioretinopathy (CSC) and pachychoroid neovasculopathy (PNV). Methods: Aqueous humor (AH) was collected from 18 acute CSC, 20 chronic CSC, and 20 PNV patients. Concentrations of 30 cytokines in the AH were analyzed using a multiplex bead immunoassay, and the cytokine profiles were compared among these three groups of patients. The areas of choroidal vascular hyperpermeability (CVH) and choroidal thickness (CT), including measurement of the vascular layers, were investigated to analyze the features of choroidal abnormality in acute CSC, chronic CSC, and PNV. Additionally, associations between cytokine profiles and choroidal abnormalities were analyzed. Results: Proinflammatory cytokines, IL-6 and IL-8 were significantly upregulated in the chronic CSC group compared with the acute CSC or PNV groups. Angiogenic cytokines and VEGF-A were upregulated at levels that almost reached significance along with disease progression from acute to chronic CSC, whereas the upregulation was not significant from chronic CSC to PNV. In the chronic CSC group, strong positive correlations were confirmed between VEGF-A and placental growth factor (PlGF) (r = 0.75, P < 0.001) and IL-6 and VEGF-A (r = 0.74, P < 0.001), and angiogenesis-related cytokines were positively correlated with the typical choroidal abnormalities, areas of CVH, mean CT, and mean large choroidal vessel layer thickness. However, there was no association between these choroidal abnormality parameters and AH cytokines in the PNV group. Conclusions: The results suggest that choroidal abnormalities in chronic CSC may be associated with upregulated angiogenesis.

This study investigated the pathophysiological features of pachychoroid neovasculopathy (PNV) and neovascular age-related macular degeneration (nAMD) by analysing and comparing cytokine profiles in aqueous humour (AH) collected from 18 PNV, 18 nAMD and 11 control patients. Responses to intravitreal injection of aflibercept were also analysed in the PNV and nAMD groups. In the PNV group, vascular endothelial growth factor (VEGF)-A was significantly lower than in the nAMD group (p = 0.03) but was almost identical to that in the control group (p = 0.86). The nAMD group showed positive correlations between interleukin (IL)-6 and IL-8 (r = 0.78, p < 0.001), IL-6 and monocyte chemoattractant protein (MCP)-1 (r = 0.68, p = 0.002) and IL-8 and MCP-1 (r = 0.68, p = 0.002). In the nAMD group, eyes with dry maculae one month after the first aflibercept injection showed significantly lower VEGF-A and placental growth factor (PlGF) at baseline than those with wet maculae (p = 0.02 for both). However, there was no significant difference between dry and wet maculae in the PNV group. The results suggest that angiogenic factors and proinflammatory cytokines may play the distinct roles in the pathogenesis of PNV and nAMD.

BACKGROUND AND AIM: Newly developed ultrathin transnasal endoscope, the GIF-XP290N, makes possible a resolving power similar to the GIF-H260 at a distance of 3 mm. We conducted surveillance of subjects with Barrett's esophagus using this ultrathin transnasal endoscopy. In Japan the lower margin of the lower esophageal palisade vessels is defined the gastroesophageal junction in deep inspiration. We diagnose Barrett's esophagus if columnar epithelium is present on the oral side of the gastroesophageal junction. METHODS AND RESULTS: Barrett's esophagus was confirmed in 116 out of 135 subjects (85.9%), with 17 cases of short-segment Barrett's esophagus (SSBE) and 99 of ultra-short-segment Barrett's esophagus. Close observation of the Barrett's esophagus mucosal structural pattern using narrow band imaging revealed 29 cases with an oval or round pattern, 29 with a long straight pattern, 47 with a villous pattern, 8 with a cerebriform pattern, and 6 with an irregular pattern according to Goda classification. Mucosal biopsies from all subjects with SSBE are examined. Histological examination revealed intestinal metaplasia in only eight subjects. We grouped the oval/round and long straight patterns as closed type, and the villous, cerebriform, and irregular patterns as open type. Analysis of the relationship between these mucosal patterns and background factors revealed a significant correlation between intestinal metaplasia and the open-type pattern. CONCLUSION: We consider this new ultrathin transnasal endoscopy to be a useful technique for surveillance of Barrett's esophagus, especially SSBE.

BACKGROUND/AIMS: To evaluate changes in fundus autofluorescence (FAF) after treatments for polypoidal choroidal vasculopathy (PCV). METHODS: Thirty-six eyes of 35 patients with treatment-naive PCV underwent intravitreal injection of ranibizumab, photodynamic therapy, or a combination of both treatments. FAF and indocyanine green angiography (ICGA) at baseline were compared with those obtained 12â months later about the changes at the affected lesion. RESULTS: In the 36 eyes, 88 polyps were detected on ICGA at baseline, and 65 (73.9%) of those showed centred hypoautofluorescence and a circumferential hyperautofluorescent ring on FAF. Twelve months later, ICGA revealed resolution of 42 of those 65 polyps. Of those 42 resolved polyps, 30 hyperautofluorescent rings (71.4%) were eliminated concurrently with the resolution of polyp. Statistical analysis revealed that an elimination of the hyperautofluorescent ring was more frequently observed in association with the resolved polyps than with the persistent polyps (p<0.0001). All the hypoautofluorescent findings corresponding to branching vascular networks at baseline were unchanged during the follow-up period. CONCLUSIONS: Elimination of the hyperautofluorescent ring is highly associated with the resolution of the polyp on ICGA. We propose that FAF has a potential as a non-invasive method of evaluating the therapeutic efficacy of treatments for PCV.

PURPOSE: To investigate the subfoveal choroidal thickness in patients with retinal angiomatous proliferation (RAP). METHODS: In consecutive patients with RAP, subfoveal choroidal thickness was retrospectively measured by the use of enhanced depth imaging spectral domain optical coherence tomography in comparison with age-matched control subjects. RESULTS: Nineteen eyes of 19 patients with RAP and 32 eyes of 32 control subjects were included in this study. No significant differences were found between the eyes with RAP and the control eyes regarding age, gender, spherical equivalent, and axial length. Mean subfoveal choroidal thickness in 19 eyes with RAP was significantly less than that in the control eyes (129.5 ± 35.8 µm vs. 201.3 ± 55.0 µm, P < 0.0001). The difference in mean subfoveal choroidal thickness between eyes with Stage 2 RAP (132.8 ± 38.2 µm) and eyes with Stage 3 RAP (126.4 ± 36.6 µm) was not significant, though each measurement was significantly less than that in the control eyes (P < 0.001 and P = 0.002, respectively). CONCLUSION: Eyes with RAP had a significantly thinner subfoveal choroid compared with normal eyes. Such morphologic features may be related to the pathologic mechanism of RAP.

PURPOSE: To investigate the relationship between the clinical characteristics of polypoidal choroidal vasculopathy (PCV) and choroidal vascular hyperpermeability seen on indocyanine green angiography. DESIGN: Retrospective, consecutive, interventional case series. METHODS: We reviewed the medical records and the angiograms of 89 patients with PCV. The relationship between choroidal vascular hyperpermeability and background factors, associated clinical manifestations, and treatment responses to intravitreal injections of ranibizumab were evaluated. RESULTS: Of the 89 patients with PCV, 31 patients (34.8%) demonstrated choroidal vascular hyperpermeability. The patients with choroidal vascular hyperpermeability more frequently showed bilateral neovascular membrane than those without choroidal vascular hyperpermeability (P=.009) and had a significant relationship with a history of central serous chorioretinopathy (CSC) (P=.01). Of the 98 eyes with treatment-naïve PCV, 34 eyes with choroidal vascular hyperpermeability demonstrated significantly greater subfoveal thickness than the 64 eyes without choroidal vascular hyperpermeability (P < .001). However, no significant relationship was found between choroidal vascular hyperpermeability and the other biomicroscopic and angiographic phenotypes of PCV. Three monthly intravitreal injections of ranibizumab were performed on 57 patients with treatment-naïve PCV, and the presence of choroidal vascular hyperpermeability was significantly related to the persistent retinal fluid 1 month after the third ranibizumab injection (P=.01). CONCLUSIONS: The patients with PCV associated with choroidal vascular hyperpermeability more frequently demonstrated bilateral neovascular membrane, a history of CSC, a thickened choroid, and poor responses to intravitreal injections of ranibizumab than those without choroidal vascular hyperpermeability.

PURPOSE: To investigate the changes in subfoveal choroidal thickness after intravitreal injections of ranibizumab (IVRs) for neovascular age-related macular degeneration (AMD). DESIGN: Prospective, consecutive, interventional case series. PARTICIPANTS: Eighty eyes (40 affected eyes with neovascular AMD and 40 unaffected fellow eyes) of 40 patients. METHODS: Forty eyes with neovascular AMD were treated with 0.5-mg IVRs monthly for 3 months and received additional IVRs as needed over the following 9-month period. Subfoveal choroidal thickness in all 80 eyes was measured by use of enhanced depth imaging optical coherence tomography images before and after starting the IVRs. MAIN OUTCOME MEASURES: Changes in subfoveal choroidal thickness after treatment by IVRs over a 12-month period. RESULTS: Twenty-three eyes (57.5%) were diagnosed with typical neovascular AMD, 16 eyes (40%) were diagnosed with polypoidal choroidal vasculopathy, and 1 eye (2.5%) was diagnosed with retinal angiomatous proliferation. Fifteen eyes (38%) had received some previous treatments for the neovascular lesion before undergoing the IVRs. The mean best-corrected visual acuity of the affected eyes was improved from 0.54 logarithm of the minimum angle of resolution units at baseline to 0.42 at 12 months (P = 0.020). The mean subfoveal choroidal thickness in the affected eyes decreased from 244±62 µm at baseline to 234±66 µm at 1 month (P = 0.013), 226±68 µm at 3 months (P<0.001), 229±67 µm at 6 months (P = 0.002), and 226±66 µm at 12 months (P = 0.002; the change ratio, 93%), whereas that in the unaffected eyes changed from 237±80 µm at baseline to 238±83 µm at 12 months (P = 0.78). In the affected eyes, the change ratio of subfoveal choroidal thickness at 12 months was not correlated with the number of IVRs (mean, 5.8±2.9). Subfoveal choroidal thickness demonstrated a similar trend toward decreasing during the following period independent of the subtypes of neovascular AMD or the treatment histories. CONCLUSIONS: Subfoveal choroidal thickness decreased after IVRs in eyes with neovascular AMD. Intravitreal injections of ranibizumab may provide a pharmacologic effect not only on the neovascular lesion but also on the underlying choroid.

PURPOSE: The purpose of the study was to describe the choroidal findings in eyes with posterior serous retinal detachment associated with inferior staphyloma by enhanced depth imaging optical coherence tomography. METHODS: The study involved five eyes of five patients with the inferior staphyloma accompanied by posterior serous retinal detachment. In each case, the upper border of the staphyloma was lying across the macula. Enhanced depth imaging spectral domain optical coherence tomography was performed in a vertical-sectional manner through the fovea, and the choroidal thicknesses at the thinnest point, at the fovea, and at 0.5 mm and 1.0 mm superior and inferior to the thinnest point were measured. Fluorescein angiography and indocyanine green angiography were also performed. RESULTS: In all 5 eyes, the choroid was thinnest at the upper border of the staphyloma (mean, 37.4 µm; SD, 13.5 µm; range, 23-53 µm). Fluorescein angiography showed a band of window defects along the upper border of the staphyloma, where indocyanine green angiography demonstrated persistent hypoperfusion in all 5 eyes. CONCLUSION: The choroid was markedly thin at the upper border of the inferior staphyloma accompanied by posterior serous retinal detachment. Such choroidal abnormality seemed to play an important role in the development of serous retinal detachment.

PURPOSE: To investigate and compare the characteristics of fundus autofluorescence (FAF) in polypoidal choroidal vasculopathy (PCV) with those in typical neovascular age-related macular degeneration (AMD). DESIGN: Retrospective, observational, consecutive case series. PARTICIPANTS: Ninety-two patients with PCV (92 affected eyes and 86 unaffected fellow eyes) and 31 patients with typical neovascular occult AMD with no classic choroidal neovascularization (31 affected eyes and 24 unaffected fellow eyes). METHODS: All study eyes underwent FAF photography with a fundus camera-based system. The incidence and distribution of hypoautofluorescence, that is, the manifestation of retinal pigment epithelium (RPE) damages, were evaluated. MAIN OUTCOME MEASURES: The characteristic FAF findings in PCV. RESULTS: In the affected eyes with PCV, the sites of the neovascular lesions showed 2 distinct FAF patterns: (1) the confluent hypoautofluorescence at the polypoidal lesions and (2) the granular hypoautofluorescence at the branching choroidal vascular networks. The confluent hypoautofluorescence, most of which was surrounded by a hyperautofluorescent ring, was seen in 74 eyes (80.4%) with PCV but was seen in no eyes with typical neovascular AMD (P < 0.001). The granular hypoautofluorescence was seen in 91 eyes (98.9%) with PCV and 27 eyes (87.1%) with typical neovascular AMD (P = 0.014). In addition, the eyes with PCV more frequently showed hypoautofluorescence outside the macular area than those with typical neovascular AMD (P = 0.021). In the unaffected fellow eyes, the hypoautofluorescence was more frequently observed in patients with PCV than in those with typical neovascular AMD, inside the macular area and in the entire FAF image (P = 0.012, P = 0.003, respectively). CONCLUSIONS: In eyes with PCV, the polypoidal lesions and the branching choroidal vascular networks appeared to affect the RPE and induce peculiar FAF findings. When compared with the patients with typical neovascular AMD, widespread RPE damage was more frequently observed in the patients with PCV, both in the affected eyes and in the unaffected fellow eyes.

It is well-known that acetylsalicylic acid induces gastrointestinal complication. Recently, trefoil factor family has been reported as a mucosal protective factor. We focused on trefoil factor family as one of defensive system for gastrointestinal injuries. The aim of this trial was to evaluate trefoil factor family levels in the serum of healthy subjects with low-dose acetylsalicylic acid. Low-dose acetylsalicylic acid with placebo or proton pump inhibitor or rebamipide were administered in 30 healthy subjects. Transnasal endoscopy was performed at 0, 24 h, 3 and 7 day. Changing of trefoil factor family (1,2,3) and numbers of gastric injuries were evaluated. The numbers of gastric injuries were significantly increased in the placebo group at 3 and 7 days. Injuries in the proton pump inhibitor group were not induced, in the rebamipide group were slightly induced. Trefoil factor family level in the placebo group were decreased in 3 and 7 days compared with prior to starting the trial. Trefoil factor family may have an important association with acetylsalicylic acid-induced gastrointestinal damage. Proton pump inhibitor and rebamipide prevented low-dose acetylsalicylic acid-induced gastrointestinal complications compared with the placebo group.
RESUMEN
BACKGROUND/AIMS: To investigate the predictive factors for the resolution of retinal fluid after intravitreal injections of ranibizumab (IVRs) for polypoidal choroidal vasculopathy (PCV). METHODS: Forty-seven eyes of 45 patients with symptomatic PCV received 0.5 mg of IVR monthly for 3 months. One month after the third IVR, the presence of dry macula, defined as absence of retinal fluid as detected by the use of optical coherence tomography, was retrospectively evaluated and correlated with clinical characteristics at baseline. Most of the eyes were followed for over 6 months. RESULTS: Of the 47 eyes, 31 eyes (66%) achieved the dry macula along with increased best-corrected visual acuity (BCVA) (0.64 to 0.46 logarithm of the minimum angle of resolution units, p<0.0001), while the other 16 eyes without dry macula showed no significant change of BCVA. Univariate analyses of the baseline characteristics identified the smaller size of the largest polyp (p=0.0008) and the absence of serous or haemorrhagic pigment epithelial detachment (p=0.045) as predictive factors for the dry macula. Multivariate logistic regression found the independent predictor for the dry macula to be the smaller size of the largest polyp (p=0.001). No severe systemic or ocular adverse events were observed. CONCLUSIONS: IVR may be helpful for resolution of retinal fluid and increased BCVA in the short term, but larger polyps and pigment epithelial detachments at baseline may be negative prognostic factors for a therapeutic response. Further studies are needed to clarify the long-term efficacy of IVR for PCV.

PURPOSE: To investigate the subfoveal choroidal thickness in eyes with typical age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV), using enhanced depth imaging optical coherence tomography. METHODS: Retrospective observational case series of 44 eyes of 44 patients (12 females and 32 males) with typical AMD or PCV located in the subfoveal region. Cross-sectional images of the choroid of each of the involved eyes were obtained by a spectral-domain OCT. The choroidal thickness under the fovea was retrospectively studied. RESULTS: Of the 44 eyes involved in this study, 21 eyes were diagnosed as typical AMD and the other 23 eyes were diagnosed as PCV. The difference in subfoveal choroidal thickness between the eyes with typical AMD (245 µm) and those with PCV (293 µm) was statistically significant, even after adjusting for age, spherical equivalent, and gender distribution (P = 0.045). When compared to eyes with subfoveal choroidal thickness less than 300 µm, those with subfoveal choroidal thickness of 300 µm or more were 5.6 times more likely to have PCV (adjusted odds ratio 5.60, 95% confidence interval 1.30-24.0, P = 0.021). CONCLUSIONS: The choroid under the fovea was thicker in eyes with PCV than those with typical AMD. This result suggests that the choroidal vascular lesion seen in PCV may not be just the choroidal neovascularization accompanied by saccular capillary dilations at the border, but may have a significant structural difference in the choroid compared to typical AMD.

BACKGROUND AND AIMS: Helicobacter pylori infection rates are reported to be high in people over the age of 40 years, but are decreasing in younger age groups. A negative correlation has been reported between H. pylori infection and reflux esophagitis (RE). METHODS: The subjects were 418 patients who underwent esophagogastroduodenoscopy and measurement of serum immunoglobulin G H. pylori antibodies examined as part of their routine health checks. Their mean age was 39.2 +/- 8.3 years (range 22-58). We analyzed the RE findings (Los Angeles classification: A, B, C, D). RESULTS: The total H. pylori infection rate was 33.7% (141/418). By age group, infection rates were 15.7% in the 20-29 years group, 28.0% in the 30-39 group, 34.3% in the 40-49 group and 69.1% in the 50-59 group. The proportion of H. pylori-negative subjects with RE was 23.5% (20-29, 22.9%; 30-39, 31.7%; 40-49, 32.4%; 50-59, 41.7%), significantly higher than that (12.1%) in H. pylori-positive subjects (20-29, 0%; 30-39, 16.7%; 40-49, 12.2%; 50-59, 10.5%). The severity of RE increased with advancing age in H. pylori-positive subjects, but not in H. pylori-negative subjects. CONCLUSION: In this study, higher rates of RE were seen in H. pylori-negative subjects. It may be, however, that the presence of H. pylori infection influences the progression of RE.
