Abstract
Septic arthritis of the sternoclavicular joint is a rare joint infection, and it sometimes leads to a chest wall abscess or mediastinitis. We report a case of a 70-year-old man who was diagnosed with empyema caused by an anterior chest wall abscess extended from septic arthritis of the sternoclavicular joint. It is very rare that arthritis causes empyema combined with an anterior chest wall abscess, and this is the first report of such a case. The patient was successfully treated with surgical drainage.

Abstract
Spontaneous regression of non-small cell lung cancer is relatively rare. Here, we present a very rare case of spontaneous regression of lung cancer which occurred in a patient with basaloid squamous cell lung cancer. To the best of our knowledge, this is the first report of such a case. A 76-year old man was referred to our hospital with nodules in the right upper lobe determined by chest computed tomography. The nodules spontaneously regressed during follow-up. Two years later, the tumor had regrown and the patient subsequently underwent surgery. The pathological findings showed basaloid squamous cell carcinoma. Stimulation of the immune system was considered to be the cause of the spontaneous regression and CD-8 positive and CD-4 positive lymphocytes might play an important role.

Abstract
We present a very rare case of spontaneous hemothorax which was caused by carcinoma of unknown primary. To the best of our knowledge, there are no other such cases reported worldwide. The patient was 72-year-old male who was referred to our department for massive hemothorax. We undertook surgical treatment for haemostasis, and found multiple tumours which led to the diagnosis of carcinoma of unknown primary as the cause of haemorrhage. The tumours increased and grew rapidly after surgery and hemothorax progressed despite our treatment. The patient died from disseminated intravascular coagulation caused by continuous bleeding on postoperative day 19.

Abstract
Here, we introduce a new method for intraoperative control of air leak using a free pericardial fat pad covering to lung damage with sutureless fixation. We covered the damaged lung tissue with a free pericardial fat pad with a polyglycol acid sheet and fibrin glue fixation. This method provides a good air leak controlling effect with the use of a free pericardial fat pad and relatively short operative time with sutureless fixation.

Abstract
Catamenial pneumothorax (CP) is reported to be caused by the endometriosis of diaphragm, lung and parietal pleura. Therefore, the resection of endometriotic lesion in these organs is reported as effective surgical treatment. Overlooking of endometrial tissues during the operation is believed to be the cause of recurrence after surgical treatment. To address this problem, we underwent total diaphragm covering (TDC) and total pleural covering with sheets of oxidized regenerated cellulose mesh. This report described two CP cases that underwent total diaphragm covering (TDC) and total pleural covering. Both patients were followed up for 1 year without recurrence.

Abstract
INTRODUCTION AND OBJECTIVES Although the complications of intravesical BCG treatment are well described, asymptomatic genitourinary granulomas after BCG therapy have rarely been reported and management strategy for these conditions remains controversial. The objective of this study is to evaluate the incidence rate of asymptomatic genitourinary granuloma formation mimicking bladder cancer recurrence after intravesical bacillus Calmette-Guérin (BCG) therapy and to identify the diagnostic and treatment strategies according to patient conditions. PATIENTS AND METHODS A retrospective review was conducted on 162 patients who underwent intravesical BCG therapy. For patients who developed granulomas, we evaluated the time interval between BCG instillation and the development of granuloma, the presence of acid-fast bacteria on pathology specimens, culture/polymerase chain reaction results, management strategies for the lesions, and clinical outcomes. RESULTS Asymptomatic genitourinary masses developed in 14 patients, of whom 5 underwent histological examinations and all were confirmed to have granulomatous inflammation. The affected organs included the kidney, bladder, prostate, and penis. While four of the five patients did not receive treatment for their granulomas, one patient was administered antituberculous medication to prevent worsening of the lesion during the perioperative period of the scheduled cystoprostatectomy. None of the patients experienced worsening or recurrence of granulomatous lesions. Patients who developed asymptomatic masses (n = 14) were significantly younger than those who did not (p = 0.0076) and multivariate analysis also showed that younger age was independently associated with the development of clinically suspicious lesions (p = 0.032); however, none of the parameters were associated with histologically confirmed granuloma formation. CONCLUSIONS Genitourinary granulomas mimicking recurrence of carcinoma may develop in nearly 10% of patients after intravesical BCG therapy. Most patients can be managed without potentially toxic antituberculosis therapy.

Abstract
Lipomas are common benign tumors, which are usually located in the subcutaneous tissue. It is relatively rare for lipoma to occur in the intrathoracic cavity, and it is clinically difficult to distinguish it from liposarcoma. We present the case of a 72-year-old man with a chest wall tumor preoperatively diagnosed as liposarcoma, with tumor enlargement with radiological image change to heterogenous and 18F-fluorodeoxyglucose positron emission tomography uptake. The tumor was resected along the chest wall, lung and diaphragm because of dense adhesions. The tumor was diagnosed as lipoma with fat necrosis and inflammatory changes.

Evaluation of interobserver measurement variability of consolidation tumor ratio of lung cancer less than 3 cm in size. Thorac Cancer 2022; 13:3018-3024.

Abstract
BACKGROUND Consolidation tumor ratio (CTR) calculated as the ratio of the tumor consolidation diameter to the tumor maximum diameter on thin-section computed tomography (CT) of lung cancer has been reported as an important prognostic factor. It has also been used for treatment decision-making. This study aimed to investigate the interobserver variability of CTR measurements on preoperative CT and propose a clinically useful CTR-based classification criterion. METHODS We enrolled 119 patients who underwent surgery for suspected or diagnosed small-sized lung cancer (≤3.0 cm in diameter). Nine doctors reviewed preoperative CT scans to measure CTR. Interobserver variability of CTR measurements was evaluated using the coefficient of variation (CV) and Fleiss' κ. The prognostic effect of the CTR-based classification was assessed using the Kaplan-Meier method. RESULTS Interobserver variability of CTR measurement was the highest for tumors with the lowest CTR (CTR = 0); it decreased as CTR increased and reached a plateaued level of low variability (CV <0.5) at CTR of 0.5. We proposed a three-group classification based on the findings of CTR interobserver variability (CTR < 0.5, 0.5 ≤ CTR < 1, and CTR = 1). Interobserver agreement of the judgment of the CTR-based classification was excellent (Fleiss' κ = 0.81). The classification significantly stratified patient prognosis (p < 0.001, 5-year overall survival rates with CTR < 0.5, 0.5 ≤ CTR < 1, and CTR = 1 were 100, 88, and 73.8%, respectively). CONCLUSIONS CTR 0.5 is a clinically relevant and helpful cutoff for treatment decision-making in patients with early-stage lung cancer based on high interobserver agreement and good prognostic stratification.

Abstract
BACKGROUND Limited information is available on the total tracheal length and its other characteristics for tracheal surgery. This study aimed to investigate the reference value of tracheal length and assess its relationship with physiological variables. METHODS We measured the tracheal length of 215 patients (107 men and 108 women) who underwent contrast-enhanced computed tomography before thoracic surgery using a three-dimensional imaging workstation. Pearson correlation analysis and multiple linear regression analysis were performed to investigate the relationship between the total tracheal length (cervical and thoracic) and common physiological parameters. RESULTS The mean total tracheal length was 11.5±1 cm (range, 8.8-14.4 cm); 8% of the patients had a total tracheal length <10 cm. The cervical trachea was significantly shorter in men than in women (2.9±1.3 vs. 3.8±1.3 cm, P<0.001), whereas the thoracic trachea was significantly longer in men than in women (8.9±1.1 vs. 7.4±1.1 cm, P<0.001). Correlation analysis showed that the total tracheal length was positively associated with height in both sexes, while the height was positively associated with only cervical tracheal length. In the multiple linear regression analysis, the total tracheal length was influenced most by height, while cervical and thoracic tracheal lengths were influenced most by sex. Older age was also an independent contributor to a shorter cervical trachea and longer thoracic trachea in both sexes. CONCLUSIONS The total tracheal length ranged from short to long in individuals, and characteristics of tracheal length varied with height, age, sex, and part of the trachea. We should thus be aware of the tracheal length of each patient for appropriate tracheal management.

Abstract
We encountered a rare case of pulmonary sequestration supplied from the right renal artery, which was resected by video-assisted thoracic surgery with carbon dioxide insufflation and indocyanine green-guided technique. A 41-year-old woman with intralobar pulmonary sequestration supplied from the right renal artery was referred to our department. At the time of surgery, we used carbon dioxide insufflation to improve the manoeuvrable workspace for shutting off aberrant arteries and indocyanine green fluorescence guidance to differentiate the boundary of the sequestered lung from the normal lung. These procedures helped in the efficient resection of the lesion.

Abstract
OBJECTIVES Following right upper lobectomy, the right middle lobe may shift towards the apex and rotate in a counterclockwise direction with respect to the hilum. This study aimed to investigate the incidence and clinical impact of middle lobe rotation in patients undergoing right upper lobectomy. METHODS From January 2014 to November 2018, 82 patients underwent right upper lobectomy at our institution for lung cancer using a surgical stapler to divide the minor fissure. Postoperative computed tomography scans evaluated the counterclockwise rotation of the middle lobe, in which the staple lines placed on the minor fissure were in contact with the major fissure of the right lower lobe (120° counterclockwise rotation). Clinicoradiological factors were evaluated and compared between patients with and without middle lobe rotation. We also reviewed surgical videos in patients with middle lobe rotation to evaluate the position of the middle lobe at the end of surgery. RESULTS Nine patients had a middle lobe rotation (11%), where 1 patient required surgical derotation. Patients with middle lobe rotation were significantly associated with more frequent right middle lobe atelectasis and severe postoperative complications compared with those without rotation. A surgical video review detected potential middle lobe rotation at the end of the surgery. CONCLUSIONS Middle lobe rotation without torsion following right upper lobectomy is not rare, and it is associated with adverse postoperative courses. Careful positioning of the right middle lobe at the end of surgery is warranted to improve postoperative outcomes.

Abstract
A 70‐year‐old man diagnosed with right‐sided malignant epithelial pleural mesothelioma, underwent pleurectomy/decortication after three courses of neoadjuvant chemotherapy. He had a history of mitral valve replacement and maze procedure with median sternotomy, and the procedures resulted in strong adhesion from the apex to the mediastinal side. In particular, the peeling of the area where the tumor invaded the pericardium required the most attention; however, the involved pericardium could be partially resected without damaging the right atrium. Finally, en bloc macroscopic complete resection with the entire pleura was successfully performed without conversion to extrapleural pneumonectomy.

Abstract
Postoperative chylothorax occurs relatively rarely after pulmonary resections, often caused intraoperatively by injury to the thoracic duct. We describe a case of postoperative chylothorax after lung cancer surgery with an aberrant thoracic duct course. A 66-year-old man showed abnormal findings on chest computed tomography (CT) during health screening and was suspected with primary lung cancer. Then, he underwent a right upper lobectomy with mediastinal lymph-node dissection. The histopathological findings confirmed lung adenocarcinoma. However, the patient developed a postoperative chylothorax and underwent revision surgery. An abnormally running thoracic duct, which was expected to flow into the right venous angle, was found at the cranial side of the right superior mediastinal dissection area and was clipped. Considering the many variations in the route of the thoracic duct, thoracic surgeons should remain alert for postoperative chylothorax when performing lung cancer surgery with mediastinal lymph-node dissection and prepare treatment strategies accordingly.

Abstract
The objective of this study was to evaluate the effects of oral administration of fiber from the first week of life on the growth and hindgut environment of preweaning calves. Twenty newborn female Holstein calves were divided into 2 groups as control and treatment. Calves in both groups were reared under the same feeding program except for oral fiber administration. Timothy hay and psyllium were mixed at a 50-to-6 ratio as a treatment diet for oral fiber administration. Calves in the treatment group were orally administered 50 g of fiber daily from 3 to 7 d of age and 100 g of fiber from 8 d of age until weaning. Feed intake and occurrence of diarrhea were recorded daily, and body weight (BW) was recorded weekly for the individual calf. Fresh feces were collected from calves at 7, 21, 35, 49, and 56 d of age to analyze fermentation parameters and microbiota to characterize the hindgut environment. Higher fiber intake in the treatment group due to oral administration of timothy and psyllium did not affect the starter intake and achieved higher BW at 21 d of age. The fecal pH, total volatile fatty acid, lactate, and ammonia nitrogen concentrations were not affected by oral fiber administration; meanwhile, the molar proportion of propionate was higher in the treatment group at 7 d of age. The difference in fecal microbiota in the calves subjected to the oral administration of fiber was observed within 21 d of life; Lactobacillus spp. and Prevotella spp. showed higher abundance, whereas that of Clostridium perfringens was decreased. These higher abundances of beneficial bacteria and lower abundance of pathogenic bacteria during early life may partly explain the higher BW of calves in the treatment group at 21 d of age. Furthermore, no adverse effect was observed for the BW and health status in the treatment group throughout the preweaning period. Therefore, early fiber feeding via oral administration potentially contributes to improving the hindgut environment in newborn calves, which leads to better growth of calves during the early stage of life.

Abstract
BACKGROUND The necessity of thoracic epidural analgesia (TEA) during minimally invasive surgery remains unclear. We investigated TEA efficacy in minimally invasive surgery vs. thoracotomy and the non-inferiority of a preemptive intercostal nerve block (ICNB) to TEA in minimally invasive surgery. METHODS We investigated 393 patients who underwent lung resection, with and without TEA, between 2014 and 2019 (242 minimally invasive surgery, 151 thoracotomy) and 93 patients who underwent minimally invasive surgery with ICNB between 2019 and 2020. To address selection bias, 70 TEA and 70 ICNB patients were propensity-score-matched. Endpoints were 1) pain score during hospitalization, 2) postoperative complications, 3) duration of operating room use, 4) analgesia-related adverse effects, and 5) use of supplemental pain medication. RESULTS One-third of patients with minimally invasive surgery discontinued TEA on postoperative day 1 or earlier; those with early TEA discontinuation reported worse pain the next day. TEA was associated with lower pain scores compared to non-TEA, regardless of surgical invasiveness, and a lower complication risk in patients with thoracotomy, but not minimally invasive surgery. For minimally invasive surgery, ICNB was associated with equivalent pain score on postoperative day 1, lower average pain score during hospitalization, shorter duration of operation room use, less frequent use of supplemental pain medication, and similar risk of postoperative complication and analgesia-related adverse effects compared to TEA after matching. CONCLUSIONS Given early TEA discontinuation after minimally invasive surgery and ICNB's non-inferior pain relief, preemptive ICNB can be an alternative for TEA in patients undergoing minimally invasive surgery.

Abstract
In our previous studies, we revealed the effect of lactose inclusion in calf starters on the growth performance and gut development of calves. We conducted the present study as a follow-up study to identify the shift in rumen microbiota and its relation to rumen fermentation when calves are fed a lactose-containing starter. Thirty Holstein bull calves were divided into 2 calf starter treatment groups: texturized calf starter (i.e., control; n = 15) or calf starter in which starch was replaced with lactose at 10% (i.e., LAC10; n = 15) on a dry matter basis. All calves were fed their respective treatment calf starter ad libitum from d 7, and kleingrass hay from d 35. Rumen digesta were collected on d 80 (i.e., 3 wk after weaning) and used to analyze rumen microbiota and fermentation products. There was no apparent effect of lactose feeding on the α-diversity and overall composition of rumen microbiota. Amplicon sequencing and real-time PCR quantification of the 16S rRNA gene confirmed that the abundance of butyrate-producing bacteria (i.e., Butyrivibrio group and Megasphaera elsdenii) did not differ between the control and LAC10 groups. Conversely, the relative abundance of Mitsuokella spp., which produce lactate, succinate, and acetate, was significantly higher in the rumen of calves that were fed lactose, whereas the lactate concentration did not differ between the control and LAC10 groups. These findings suggest that the lactate production can be elevated by an increase of Mitsuokella spp. and then converted into butyrate, not propionate, since the proportion of propionate was lower in lactose-fed calves. In addition, we observed a higher abundance of Coriobacteriaceae and Pseudoramibacter-Eubacterium in the LAC10 group. Both these bacterial taxa include acetate-producing bacteria, and a positive correlation between the acetate-to-propionate ratio and the abundance of Pseudoramibacter-Eubacterium was observed. Therefore, the higher abundance of Coriobacteriaceae, Mitsuokella spp., and Pseudoramibacter-Eubacterium in the rumen of lactose-fed calves partially explains the increase in the proportion of rumen acetate that was observed in our previous study.

Diagn Pathol 2021; 16:54. [PMID: 34127031 PMCID: PMC8204458 DOI: 10.1186/s13000-021-01110-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2021] [Accepted: 05/27/2021] [Indexed: 11/18/2022] Open
Abstract
Background The novel SS18-SSX fusion-specific antibody is reported to have high sensitivity and specificity for the diagnosis of primary synovial sarcoma (SS), which often metastasizes to the lung. Thus far, no study has validated the diagnostic efficacy of SS18-SSX antibody for pulmonary metastatic SS. Therefore, we aimed to investigate the usefulness of the SS18-SSX antibody in the diagnosis of pulmonary metastatic SS. Methods We evaluated the immunohistochemistry of SS18-SSX fusion-specific antibody (E9X9V) in 10 pulmonary metastatic SS cases and the corresponding five primary sites (four limbs and one mediastinum) in five patients, for whom SS was already diagnosed and confirmed by fluorescence in-situ hybridization in the metastatic and primary sites, and in 93 clinical and histologic mimics including 49 non-SS, pulmonary metastatic sarcomas, 39 primary lung cancers, and five intrathoracic solitary fibrotic tumors. All specimens were surgically resected at Shinshu University Hospital during 2001–2019. For primary and metastatic SS, we also evaluated SS18-SSX immunohistochemistry using needle biopsy and touch imprint cytology specimens from the primary site. Results SS18-SSX staining was diffusely-strongly positive in all 10 pulmonary metastatic SS cases and the corresponding five primary sites; whereas, it was negative in all 93 clinical and histologic mimics (100% sensitivity and 100% specificity). Further, SS18-SSX staining was also sufficiently positive in the biopsy and cytology specimens. Conclusions Immunohistochemistry of the SS18-SSX fusion-specific antibody is useful for the differential diagnosis of pulmonary metastatic SS in clinical practice. This simple and reliable method has the potential to replace traditional genomic tests. However, further studies are warranted in this regard.

Abstract
295 Background: Several biomarkers based on serum chemistry have been reported to be associated with the prognosis of several types of cancers. This retrospective study aimed to investigate the prognostic value of preoperative mGPS and NLR after curative resection for gastric cancer. Methods: A total of 295 patients who underwent curative gastrectomy for primary gastric cancer at our institution from January 2013 to December 2017 were enrolled in this study. The mGPS was calculated by CRP and Alb using standard thresholds ( > 0.5 mg/dL for CRP and < 3.5 g/dL for Alb). The NLR was defined as absolute neutrophil count divided by absolute lymphocyte count. The survival curves of patients stratified by each parameter were plotted by the Kaplan-Meier method and compared by log-rank test. Multivariate Cox proportional hazards regression models were used to select parameters independently correlated with prognosis. Results: The median follow-up time was 36.7 months, and 29 patients died during follow-up. The estimated 5-year survival rate was 83.1%. Results from the univariate analyses showed mGPS2 (CRP > 0.5 mg/dL and Alb < 3.5 g/dL) was associated with poor survival while NLR and NLRc was not (P < 0.001, P = 0.506, and P = 0.423, respectively). In the multivariate analyses, the mGPS2 was identified as an independent predictive factor for OS in gastric cancer patients after curative resection (HR: 2.624; 95% CI: 1.058-6.505; P = 0.037). Conclusions: Preoperative mGPS2 was associated with worse survival after curative resection of gastric cancer patients. Based on our study, those with mPGS2 may be warranted to receive additional therapy or nutritional support to acquire better survival.
