A case of acinar cell carcinoma originating from the accessory papilla of the duodenum.

CASE PRESENTATION: A 61-year-old female was referred to our hospital with a neoplastic lesion in the duodenum. Computed tomography with contrast enhancement revealed a 10-mm tumor in the duodenum. Upper gastrointestinal endoscopy revealed a submucosal tumor-like lesion in the descending part of the duodenum. Endoscopic ultrasound revealed a well-defined hypoechoic tumor. Biopsy and immunohistochemical findings including negative Synaptophysin and Chromogranin A staining and positive Trypsin and BCL10 staining suggested a carcinoma with acinar cell differentiation. Pancreatoduodenectomy was performed, and the resected specimen had a 15-mm solid nodule in the submucosal layer of the duodenum. Pancreatogram of the resected specimen revealed a tumor localized in the accessory papilla region. In histopathological examination, the tumor was found in the submucosa of the duodenum with pancreatic tissue present nearby, and these were separated from the pancreatic parenchyma by the duodenal muscle layer. These findings led to a diagnosis of acinar cell carcinoma originating from the accessory papilla of the duodenum. CONCLUSION: Acinar cell carcinoma originating from the accessory papilla of the duodenum is exceptionally rare, with no reported cases to date. The origin was considered to be pancreatic tissue located in the accessory papilla region.

Novel Repair Technique for Oral and Anal Side Stoma Prolapse of a Loop Colostomy With the Stapled Modified Altemeier Method Using Indocyanine Green Fluorescence Imaging.

BACKGROUND/AIM: Stoma prolapse is a common complication in the late phase after stoma creation. With advances in chemotherapy, a double-orifice colostomy or ileostomy and chemotherapy are used to treat primary unresectable colorectal cancer. Preoperative therapy with a double-orifice colostomy or ileostomy is performed to aid primary colorectal cancer miniaturization. Therefore, the number of stoma prolapses will likely increase in the future. Previous reports on the repair of stoma prolapse focused on unilateral stoma prolapse of loop colostomy, and there are no reports about the bilateral stoma prolapse of loop colostomy or ileostomy. CASE REPORT: We report a novel repair technique for oral and anal side (bilateral) stoma prolapse of a loop colostomy with the stapled modified Altemeier method using indocyanine green (ICG) fluorescence imaging considering the distribution of marginal artery in preventing marginal artery injury which has considerable clinical significance. CONCLUSION: Our novel technique for the oral and anal side prolapse of a loop colostomy is considered effective and safe.

Imaging findings in inflammatory disease of the genital organs.

This review focuses on inflammatory diseases of female and male genital organs and discusses their epidemiology, pathogenesis, clinical presentation, and imaging findings. The female section covers pelvic inflammatory disease (PID) primarily caused by sexually transmitted infections (STIs) that affect the uterus, fallopian tubes, and ovaries. Unusual causes such as actinomycosis and tuberculosis have also been explored. The male section delves into infections affecting the vas deferens, epididymis, testes, prostate, and seminal vesicles. Uncommon causes such as tuberculosis, and Zinner syndrome have also been discussed. In addition, this review highlights other conditions that mimic male genital tract infections such as vasculitis, IgG4-related diseases, and sarcoidosis. Accurate diagnosis and appropriate management of these inflammatory diseases are essential for preventing serious complications and infertility. Imaging modalities such as ultrasound, magnetic resonance imaging, and computed tomography play a crucial role in diagnosis. Understanding the diverse etiologies and imaging findings is vital for the effective management of inflammatory diseases of the genital organs.

Lupus-like membranous nephropathy during the postpartum period expressing glomerular antigens exostosin 1/exostosin 2 and phospholipase A2 receptor: a case report.

Recently, several target antigens of membranous nephropathy (MN), such as phospholipase A2 receptor (PLA2R) and exostosin 1/exostosin 2 (EXT1/2), have been discovered. A 30-year-old woman was referred to our hospital with nephrotic range proteinuria and microscopic hematuria. She was first noted to have proteinuria before pregnancy, and her proteinuria worsened in the postpartum period. A renal biopsy showed MN. Immunofluorescence microscopy showed IgG, IgA, IgM, C3, C4, and C1q depositions in the mesangial area and glomerular capillary walls (GCWs). Regarding the IgG subclass, IgG1 and IgG3 were detected on glomeruli. Electron microscopy showed subepithelial electron-dense deposits (EDDs). EDDs were also detected in paramesangial and subendothelial areas. The diagnosis of membranous lupus nephritis (MLN) was suspected, but she did not fulfill the criteria for systemic lupus erythematosus. Neither anti-nuclear antibody nor hypocomplementemia were detected. We further evaluated glomerular EXT1/2 expressions, which were evident on GCWs. In addition, PLA2R was also detected on GCWs, although serum antibody for PLA2R was negative. She responded to immunosuppressive therapy with decreased proteinuria. In the present case, glomerular PLA2R expression implied the possibility of primary MN. However, pathological findings with a full-house staining pattern and glomerular EXT1/2 expressions were very similar to those of lupus-associated MN. Glomerular PLA2R expression appeared not to reflect immunocomplexes of PLA2R and autoantibody when considering the results for glomerular IgG subclass and the absence of serum anti-PLA2R antibody. Collectively, it is plausible that this was a case of a relatively young postpartum female who developed latent MLN rather than primary MN.

Critical swallowing functions contributing to dysphagia in patients with recurrent laryngeal nerve paralysis after esophagectomy.

BACKGROUND: Recurrent laryngeal nerve paralysis (RLNP) after esophagectomy can cause aspiration because of incomplete glottis closure, leading to pneumonia. However, patients with RLNP often have preserved swallowing function. This study investigated factors that determine swallowing function in patients with RLNP. METHODS: Patients with esophageal cancer who underwent esophagectomy and cervical esophagogastric anastomosis were enrolled between 2017 and 2020. Videofluoroscopic examination of swallowing study (VFSS) and acoustic voice analysis were performed on patients with suspected dysphagia including RLNP. Dysphagia in VFSS was defined as score ≥ 3 of the 8-point penetration-aspiration scale VFSS and acoustic analysis results related to dysphagia were compared between patients with and without RLNP. RESULTS: Among 312 patients who underwent esophagectomy, 74 developed RLNP. The incidence of late-onset pneumonia was significantly higher in the RLNP group than in the non-RLNP (18.9 vs. 8.0%, P = .008). Detailed swallowing function was assessed by VFSS in 84 patients, and patients with RLNP and dysphagia showed significantly shorter maximum diagonal hyoid bone elevation (10.62 vs. 16.75 mm; P = .003), which was a specific finding not seen in patients without RLNP. For acoustic voice analysis, the degree of hoarseness was not closely related to dysphagia. The length of oral intake rehabilitation for patients with and without RLNP was comparable if they did not present with dysphagia (8.5 vs. 9.0 days). CONCLUSIONS: Impaired hyoid bone elevation is a specific dysphagia factor in patients with RLNP, suggesting compensatory epiglottis inversion by hyoid bone elevation is important for incomplete glottis closure caused by RLNP.

Stress Response Pattern of Heart Rate Variability in Patients with Functional Somatic Syndromes.

Functional somatic syndromes (FSSs) represent a clinically important group of disorders that are often stress-related. Their autonomic pathophysiology, including reduced heart rate variability (HRV), has been reported. However, the response pattern to mental stress and recovery in FSSs remains unclear. Thus, we aimed to clarify the pattern of autonomic stress response and recovery to mental arithmetic stress in patients with FSS compared to that in healthy controls. This cross-sectional study included 79 patients with FSS who visited the Department of Psychosomatic Medicine at a university hospital in Japan and 39 healthy controls. Following a mood questionnaire and obtaining epidemiologic information, HRV was measured during three periods (5 min each): relaxation baseline resting, stress (mental arithmetic task), and post-stress recovery period. The HRV analysis included inter-beat interval, low frequency power, and high frequency power. Compared to healthy controls, patients with FSS exhibited significantly higher scores on the mood questionnaire, prolonged duration of illness, and decreased functionality in daily activities. While the healthy control group showed a pronounced stress response pattern with a significant decrease in vagal HRV and recovery, the FSS group showed a "flat" vagal stress response pattern, and the HRV in the FSS group was lower at relaxation baseline, remained low during the stress, and did not change post stress. Patients with severe FSS exhibit an altered stress response pattern. Our results could provide significant clues for the diagnosis and treatment of such patients, as well as useful insights into the relationship between stress and illness.

Three cases of open surgical procedures on ileal conduits for the repair of benign ureteroenteric anastomotic strictures after total pelvic exenteration of rectal tumors.

Ureteroenteric anastomotic strictures (UEAS) are typical complications after creating an ileal conduit for total pelvic exenteration (TPE) of rectal tumors. We report the ileal conduit for reconstruction in three patients, in the age-range of 47-73 years. Case 1 was when a left-sided UEAS had sufficient length of ureter for anastomosis, Case 2 was a right-sided UEAS with sufficient length of ureter for anastomosis, and Case 3 was a left-sided UEAS with insufficient length of ureter for anastomosis. There were no complications after operation and no recurrence of UEAS. It is important to learn the open surgical procedures for repair of a benign UEAS after TPE of rectal cancers. This has fewer complications and is safe in the long term.

How many times can patients tolerate reoperation for the local recurrence of colorectal cancer in terms of complications?

The frequency of resection for the recurrence of colorectal cancer has not been investigated in previous studies. Likewise, the related postoperative complications and the limit for indicating surgical resection has not been reported. Herein, we reported the complications of a highly frequent surgical approach for rectal cancer recurrence, i.e., exceeding three reoperations, based on our clinical experience. We included 15 cases exceeding two operations for the local recurrence of colorectal cancer from 2014 to 2019. We examined the postoperative complications classified as Clavien?Dindo IIIb. The positive rates of the complications were 0 (0.0%), 0 (0.0%), 2 (13.3%), 3 (37.5%), and 0 (0.0%) for the primary, 1st recurrent, 2nd recurrent, 3rd recurrent, and 4th recurrent operation group (p=0.027), respectively. It is important to exercise caution in handling cases exceeding two reoperations (exceeding three reoperations including the primary operation). J. Med. Invest. 70 : 369-376, August, 2023.

Novel Ureteral Stent Catheterization Technique for Treating Hyperchloremic Metabolic Acidosis After Total Pelvic Exenteration.

BACKGROUND/AIM: Hyperchloremic metabolic acidosis after total pelvic exenteration (TPE) is relatively rare. Urinary diversion of the ileal conduit during TPE can result in increased urine reabsorption leading to hyperchloremic metabolic acidosis. We developed a new technique for the retrograde catheterization of a ureteral stent into an ileal conduit to treat hyperchloremic metabolic acidosis. CASE REPORT: A 70-year-old man underwent TPE for locally recurrent rectal cancer. Multiple episodes of complications, such as hyperchloremia and metabolic acidosis, occurred. Effective drainage of urine from the ileal conduit is crucial. With collaboration between an endoscopist and a radiologist, we developed a novel method for retrograde catheterization of the ureteral stent into an ileal conduit for hyperchloremic metabolic acidosis after TPE. The patient's condition quickly improved after the procedure. CONCLUSION: Our novel technique of retrograde catheterization of a ureteral stent into an ileal conduit for hyperchloremic metabolic acidosis could be adopted worldwide, as it is effective and safe.

Skeletal Muscle Quality and Quantity Affect Prognosis after Neoadjuvant Chemotherapy with a Triple Regimen of Docetaxel/Cisplatin/5-FU in Patients with Esophageal Cancer.

The purpose of this study was to identify factors associated with the prognosis after docetaxel, cisplatin, and 5-fluorouracil (DCF) neoadjuvant chemotherapy (NAC) in patients with advanced esophageal squamous cell carcinoma (ESCC) undergoing surgical resection. We retrospectively examined a total of 100 patients who received neoadjuvant DCF therapy for ESCC at our institution between 2011 and 2020. The psoas muscle index (PMI) was calculated from the psoas muscle area at the L3 vertebral level, and the intramuscular adipose tissue content (IMAC) was calculated from the mean CT value of the multifidus muscle and from four points of subcutaneous fat. The median PMI value was 6.11 cm2/m2 (range, 3.12-11.07 cm2/m2) in men and 3.65 cm2/m2 (range, 2.70-6.82 cm2/m2) in women. The median IMAC was -0.426 (range, -0.079--0.968) in men and -0.359 (range, -0.079--0.671) in women. Based on the PMI, IMAC, and other patient factors, factors associated with NAC-DCF postoperative survival were identified using multivariate Cox regression analysis. A high IMAC was significantly related to overall survival after surgery (p = 0.005, hazard ratio 2.699). A comparison of Kaplan-Meier curves showed that the 5-year survival rate was 76.5% in the low IMAC group and 42.7% in the high IMAC group (log-rank test; p = 0.001). A low IMAC was associated with good survival outcomes and was an independent prognostic factor in patients with cStage II/III ESCC who were treated with the NAC-DCF regimen and underwent surgical resection.

Patients with postprandial distress syndrome experience problems with their interoceptive perceptual function to the gastric region, but their heartbeat perception is normal: a case control study.

BACKGROUND: Visceral hypersensitivity in functional dyspepsia can be localized or widespread, and there is no simple method of assessment. Measuring interoceptive accuracy at different sites provides an assessment of perceptual hypersensitivity to specific ecological phenomena. The purpose of this study was to characterize visceral hypersensitivity by comparing gastric sensory and cardiac perceptual tests in patients with postprandial distress syndrome and in healthy volunteers. METHODS: Sixteen patients with postprandial distress syndrome (age = 47.5 ± 17.4, all female) and 16 healthy volunteers (age = 43.3 ± 16.1, all female) participated in the study after a six-hour fast. Each participant answered questionnaires about physical and mental quality of life, depression and anxiety, tendency of alexithymia, and somatosensory amplification. After completing the questionnaire, the participants took the heartbeat tracking task and the five-minute water load test. We performed statistical analysis using the Mann-Whitney U test and Spearman's rank correlation coefficient. RESULTS: Subjects with postprandial distress syndrome had a lower drinking capacity than healthy volunteers (postprandial distress syndrome = 360.9 ± 170.0 mL, healthy volunteers = 644.1 ± 297 mL, P = 0.009), but there was no significant difference in the heartbeat perception score (postprandial distress syndrome = 0.599 ± 0.175, healthy volunteers = 0.623 ± 0.181, P = 0.647). There was a negative correlation (r = - 0.509, P < 0.05) between drinking capacity and the heartbeat perception score in healthy volunteers, but no correlation in postprandial distress syndrome (r = - 0.156, P = 0.564). Heartbeat perception score did not correlate with psychological measures. CONCLUSIONS: Compared with healthy volunteers, only the five-minute water load test values were reduced in patients with postprandial distress syndrome, and no difference was observed in the heartbeat tracking task. Combining the 5-minute water load test and the heart rate tracking task revealed a lost cardiac-gastric perceptual relationship in patients with postprandial distress syndrome that was not observed in healthy volunteers, suggesting that there is hypersensitivity in gastric interoceptive perceptual function. Performing sensory examinations at two different sites may be useful in clarifying whether visceral hypersensitivity is localized. TRIAL REGISTRATION: UMIN000057586.

Clinical Impact of Radical Resection of Synchronous and Metachronous Peritoneal Metastases from Colorectal Cancer.

BACKGROUND: According to some case series, patients with colorectal cancer (CRC) who underwent radical resection of synchronous peritoneal metastases (PM) with the primary tumor had better survival than patients who underwent non-surgical treatment. However, little evidence exists regarding the significance of radical resection for metachronous PM. OBJECTIVE: This study aimed to evaluate the clinical significance of surgical intervention for isolated PM from CRC, with a particular focus on time to PM. METHODS: A total of 74 consecutive patients with isolated PM from CRC, including 40 and 34 patients with synchronous and metachronous PM, respectively, treated between 2007 and 2018 were retrospectively analyzed. The primary outcome measure was overall survival (OS) from diagnosis, and the OS was compared between radical resection and palliative chemotherapy. RESULTS: Five-year OS was 39.7% for all patients. Patients with radical resection had significantly better 5-year OS compared with those with palliative chemotherapy (62.8% vs. 11.0%; p < 0.0001). According to time to PM, patients with radical resection had significantly better 5-year OS compared with those with palliative chemotherapy for both synchronous PM (47.6% vs. 0%; p = 0.019) and metachronous PM (77.2% vs. 15.2%; p < 0.0001). Multivariable analysis stratified by time to PM revealed that surgical intervention is a significant favorable prognostic factor only in patients with metachronous PM (hazard ratio 0.117, 95% confidence interval 0.020-0.678; p = 0.017). CONCLUSIONS: Patients with radical resection of PM had good survival compared with those with chemotherapy alone, especially for metachronous PM. Surgical intervention should be considered for isolated metachronous PM when radical resection is feasible.

Rare case of exostosin 1/exostosin 2-related membranous lupus nephritis concomitant with dual ANCA- and anti-GBM antibody-associated crescentic glomerulonephritis effectively diagnosed by mass spectrometry: a case report.

BACKGROUND: Recent developments in mass spectrometry (MS) have revealed target antigens for membranous nephropathy (MN), including phospholipase A2 receptor and exostosin 1/exostosin 2 (EXT1/2). EXT1/2 are known antigens of autoimmune disease-related MN, especially membranous lupus nephritis. We describe the case of an elderly man who developed nephrotic syndrome followed by progressive renal dysfunction. CASE PRESENTATION: A 78-year-old man presented with rapidly progressive renal dysfunction with proteinuria and hematuria. Three years previously, he had developed leg edema but did not receive any treatment. Laboratory tests showed elevated anti-nuclear antibody (Ab), anti-dsDNA Ab titer, and hypocomplementemia, indicating systemic lupus erythematous. Myeloperoxidase anti-neutrophil cytoplasmic Ab (ANCA) and anti-glomerular basement membrane (GBM) Ab were also detected. The renal pathologic findings were compatible with crescentic glomerulonephritis (GN), whereas non-crescentic glomeruli exhibited MN without remarkable endocapillary or mesangial proliferative change. Immunofluorescence microscopy revealed glomerular IgG, C3, and C1q deposition. All IgG subclasses were positive in glomeruli. Anti-PLA2R Ab in serum was negative. MS analysis was performed to detect the antigens of MN, and EXT1/2 was detected in glomeruli. Therefore, we reached a diagnosis of membranous lupus nephritis concurrent with both ANCA-associated vasculitis and anti-GBM-GN. The simultaneous occurrence of these three diseases is extremely rare. CONCLUSIONS: This is the first report of EXT1/2-related membranous lupus nephritis concurrent with ANCA-associated vasculitis and anti-GBM-GN. This case demonstrates the usefulness of MS in diagnosing complicated cases of MN.

Maximum phonation time: an independent predictor of late-onset pneumonia after esophageal cancer surgery.

Dysphagia after esophagectomy is a major risk factor for aspiration pneumonia, thus preoperative assessment of swallowing function is important. The maximum phonation time (MPT) is a simple indicator of phonatory function and also correlates with muscle strength associated with swallowing. This study aimed to determine whether preoperative MPT can predict postoperative aspiration pneumonia. The study included 409 consecutive patients who underwent esophagectomy for esophageal cancer between 2017 and 2021. Pneumonia detected by routine computed tomography on postoperative days 5-6 was defined as early-onset pneumonia, and pneumonia that developed later (most often aspiration pneumonia) was defined as late-onset pneumonia. The correlation between late-onset pneumonia and preoperative MPT was investigated. Patients were classified into short MPT (<15 seconds for males and <10 seconds for females, n = 156) and normal MPT groups (≥15 seconds for males and ≥10 seconds for females, n = 253). The short MPT group was significantly older, had a lower serum albumin level and vital capacity, and had a significantly higher incidence of late-onset pneumonia (18.6 vs. 6.7%, P < 0.001). Multivariate analysis showed that short MPT was an independent risk factor for late-onset pneumonia (odds ratio: 2.26, P = 0.026). The incidence of late-onset pneumonia was significantly higher in the short MPT group (15.6 vs. 4.7%, P = 0.004), even after propensity score matching adjusted for clinical characteristics. MPT is a useful predictor for late-onset pneumonia after esophagectomy.

Clinico-Pathogenic Similarities and Differences between Infection-Related Glomerulonephritis and C3 Glomerulopathy.

Recently, the comprehensive concept of "infection-related glomerulonephritis (IRGN)" has replaced that of postinfectious glomerulonephritis (PIGN) because of the diverse infection patterns, epidemiology, clinical features, and pathogenesis. In addition to evidence of infection, hypocomplementemia particularly depresses serum complement 3 (C3), with endocapillary proliferative and exudative GN developing into membranoproliferative glomerulonephritis (MPGN); also, C3-dominant or co-dominant glomerular immunofluorescence staining is central for diagnosing IRGN. Moreover, nephritis-associated plasmin receptor (NAPlr), originally isolated from the cytoplasmic fraction of group A Streptococci, is vital as an essential inducer of C3-dominant glomerular injury and is a key diagnostic biomarker for IRGN. Meanwhile, "C3 glomerulopathy (C3G)", also showing a histological pattern of MPGN due to acquired or genetic dysregulation of the complement alternative pathway (AP), mimics C3-dominant IRGN. Initially, C3G was characterized by intensive "isolated C3" deposition on glomeruli. However, updated definitions allow for glomerular deposition of other complement factors or immunoglobulins if C3 positivity is dominant and at least two orders of magnitude greater than any other immunoreactant, which makes it challenging to quickly distinguish pathomorphological findings between IRGN and C3G. As for NAPlr, it was demonstrated to induce complement AP activation directly in vitro, and it aggravates glomerular injury in the development of IRGN. A recent report identified anti-factor B autoantibodies as a contributing factor for complement AP activation in pediatric patients with PIGN. Moreover, C3G with glomerular NAPlr deposition without evidence of infection was reported. Taken together, the clinico-pathogenic features of IRGN overlap considerably with those of C3G. In this review, similarities and differences between the two diseases are highlighted.

Mediation analysis unveils a carcinogenic effect of ADH1B rs1229984 through mechanisms other than change in drinking intensity: oesophageal cancer case-control study.

BACKGROUND: Ingested alcohol is predominantly oxidized to acetaldehyde by alcohol dehydrogenase 1B (ADH1B), and acetaldehyde is further oxidized to acetate mainly by aldehyde dehydrogenase 2 (ALDH2). Although alcohol consumption is a convincing risk factor for oesophageal cancer, the role of ADH1B rs1229984 (His48Arg), the single-nucleotide polymorphism associated with slow alcohol metabolism, in oesophageal cancer development is unclear. Because this single-nucleotide polymorphism is associated with both increased risk of oesophageal cancer and drinking intensity, its association with oesophageal cancer might operate either through a direct pathway independently of drinking intensity, via an indirect pathway mediated by drinking intensity, or both. METHODS: To disentangle these different pathways, we applied a mediation analysis to an oesophageal cancer case-control study (600 cases and 865 controls) by defining the ADH1B Arg allele and alcohol consumption as exposure and mediator, respectively, and decomposed the total-effect odds ratio of the ADH1B Arg allele into direct- and indirect-effect odds ratio. RESULTS: The ADH1B Arg allele was associated with oesophageal cancer risk through pathways other than change in drinking intensity (direct-effect odds ratio, 2.03; 95% confidence interval, 1.41-2.92), in addition to the indirect pathway mediated by drinking intensity (indirect-effect odds ratio, 1.27; 95% confidence interval, 1.05-1.53). Further analyses by stratifying genotypes of ALDH2 rs671 (Glu504Lys), the functional single-nucleotide polymorphism that strongly attenuates the enzymatic activity, showed significant direct-effect odds ratio within each stratum. CONCLUSIONS: These results indicate that ADH1B Arg allele contributes to oesophageal cancer risk by slowing alcohol breakdown, in addition to its effect on the amount of alcohol consumed.

Clinical Relevance of Lateral Pelvic Lymph Node Dissection for Enlarged Lateral Nodes in Locally Advanced Low Rectal Cancer without Preoperative Treatment.

Objectives: The present study aimed to investigate the clinical relevance of lateral pelvic lymph node dissection (LPLND) in low rectal cancer without preoperative treatment, with a focus on the presence of LPLN enlargement in preoperative imaging. Methods: Consecutive patients with cT3 to T4 low rectal cancer who underwent mesorectal excision and LPLND without preoperative treatment between 2007 and 2018 at a single dedicated cancer center were included. LPLN short-axis diameter (SAD) measured using preoperative multi-detector row computed tomography (MDCT) was evaluated retrospectively. Results: A total of 195 consecutive patients were analyzed. Overall, 101 (51.8%) and 94 (48.2%) patients had visible and no visible LPLNs in preoperative imaging, including 56 (28.7%), 28 (14.4%), and 17 (8.7%) patients had SADs of <5 mm, 5-7 mm, and ≥7 mm, respectively. Incidence of pathologically confirmed LPLN metastasis were 18.1%, 21.4%, 28.6%, and 52.9%, respectively. Overall, thirteen (6.7%) patients developed local recurrence (LR), including one patient who developed lateral recurrence, yielding a 5-year cumulative risk for LR of 7.4%. Five-year RFS and OS for all patients were 69.7% and 85.7%, respectively. No differences were observed in the cumulative risk for LR and OS between any pairs of groups. Conclusions: No significant difference was observed in the cumulative risk for LR and OS regardless of LPLN SAD, implying the good impact of LPLND on the prevention of lateral recurrence, as well as the difficulty of predicting LPLN metastasis using only LPLN SAD in preoperative imaging.

Tailored opening questions to the context of using medical questionnaires: Qualitative analysis in first-visit consultations.

Background: Communication skills required for doctors do not consist of simple uses of particular linguistic forms but include uses that are sensitive to the interactional context. In consultations where the doctors have pre-existing information about their patients, this can complicate the context of problem solicitation. We investigated how doctors tailor opening questions to a context in which they get pre-existing information from a medical questionnaire (MQ) filled out by the patients. Methods: The data for this study were 87 video recordings of first visits to the department of general medicine at a university hospital in Japan. We qualitatively analyzed doctors' practices in problem solicitation in an opening phase using conversation analysis and triangulated it with quantitative analysis. Results: Open-ended questions accounted for 26.4% of opening questions. Among the closed-ended questions, 75.0% were confirming questions about symptoms. In cases with open-ended questions, doctors minimized the relevance of the MQ to problem solicitation by giving license to repeat the description from the MQ. In cases with closed-ended questions, doctors highlighted the relevance of the MQ by sharing the MQ. Through these practices, they avoided patients' possible confusion about problem presentation while simultaneously maximizing the possibility of soliciting the patients' narratives. Conclusions: Doctors adjusted the level of relevance of pre-existing information to problem solicitation through both verbal and nonverbal management of the MQ. It will be useful to instruct such context-dependent practices to improve communication skills in medical school curriculum.

Real-world management and outcomes of older patients with locally advanced esophageal squamous cell carcinoma: a multicenter retrospective study.

BACKGROUND: Neoadjuvant chemotherapy (NAC) followed by surgery is the standard treatment for locally advanced esophageal squamous cell carcinoma (ESCC). Chemoradiotherapy (CRT) is an alternative treatment approach. However, both treatments are associated with toxicity, and the optimal treatment for older patients with ESCC is unknown. This study aimed to evaluate the treatment strategies and prognosis of older patients with locally advanced ESCC in a real-world setting. METHODS: We retrospectively evaluated 381 older patients (≥ 65 years) with locally advanced ESCC (stage IB/II/III, excluding T4) who received anticancer therapy at 22 medical centers in Japan. Based on age, performance status (PS), and organ function, the patients were classified into two groups: clinical trial eligible and ineligible groups. Patients aged ≤ 75 years with adequate organ function and a PS of 0-1 were categorized into the eligible group. We compared the treatments and prognoses between the two groups. RESULTS: The ineligible group had significantly shorter overall survival (OS) than the eligible group (hazard ratio [HR] for death, 1.65; 95% confidence interval [CI], 1.22-2.25; P = 0.001). The proportion of patients receiving NAC followed by surgery was significantly higher in the eligible group than in the ineligible group (P = 1.07 × 10-11), whereas the proportion of patients receiving CRT was higher in the ineligible group than in the eligible group (P = 3.09 × 10-3). Patients receiving NAC followed by surgery in the ineligible group had comparable OS to those receiving the same treatment in the eligible group (HR, 1.02; 95% CI, 0.57-1.82; P = 0.939). In contrast, patients receiving CRT in the ineligible group had significantly shorter OS than those receiving CRT in the eligible group (HR, 1.85; 95% CI, 1.02-3.37; P = 0.044). In the ineligible group, patients receiving radiation alone had comparable OS to those receiving CRT (HR, 1.13; 95% CI, 0.58-2.22; P = 0.717). CONCLUSIONS: NAC followed by surgery is justified for select older patients who can tolerate radical treatment, even if they are old or vulnerable to enrollment in clinical trials. CRT did not provide survival benefits over radiation alone in patients ineligible for clinical trials, suggesting the need to develop less-toxic CRT.

Evaluating Risk Factors for Developing Allergic Reactions during Plasma Exchange Using Fresh-frozen Plasma: A Single-center Retrospective Study.

Objective Allergic reactions are a severe complication of plasma exchange (PEx). Few reports have analyzed allergic reactions during PEx using fresh-frozen plasma (FFP) as a replacement solution. We therefore clarified the relationship between risk and exacerbation factors that lead to the onset of PEx-related allergic reactions, particularly PEx, using FFP, and examined whether or not allergic reactions were predictable. Methods This retrospective study included 88 consecutive patients who underwent PEx with FFP as a replacement solution at Kitasato University Hospital. The patients were grouped according to the presence of allergic reactions and compared. Data were analyzed using the χ2 test, Mann-Whitney U test, and a binomial logistic analysis. Statistical analyses were performed using EZR software program, version 1.54, with p<0.05 considered statistically significant. Results There were 44 allergic reaction cases. The average time to the onset of an allergic reactions was 63.5 (45-93) minutes. The allergic reaction-onset group had significantly higher average albumin (Alb) levels than did the non-allergic reaction-onset group. The binomial logistic analysis identified Alb levels as independent risk factors for allergic reactions. The receiver operating characteristic analysis identified an Alb level ≥3.4 g/dL as a risk factor for allergic reactions (area under the curve: 0.731; 95% confidence interval: 0.622-0.84). Conclusion Allergic reaction onset occurred approximately one hour after PEx initiation in the critical period. A serum Alb level ≥3.4 g/dL was identified as a risk factor for predicting allergic reactions. Patients with Alb levels ≥3.4 g/dL at the first PEx should be monitored for allergic reaction symptoms.
