A 39-year-old woman was referred for assessment of abnormality of on a CT scan with a vascular anomaly of the aortic arch. This patient was completely asymptomatic with no concomitant pathologies and no reported prior trauma. Laboratory data for syphilitic or other microbial infections were negative. The diagnosis was confirmed by angiographic computed tomographic scan with 3-dimensional reconstruction. This technique documented the presence of the aneurysm and the left subclavian artery arising from the unique form of aneurysm. Early surgery was preferred because of the young age of the patient and the morphology and the size of the aneurysm (50 mm). Surgery was performed by a left postero-lateral thoracotomy through the forth intercostal space. Femoro-femoral partial cardiopulmonary bypass was used for distal perfusion. An aortic clamp was placed just distal to the left carotid artery, and a second clamp was placed in the descending thoracic aorta. The aortic isthmus was replaced with a 20-mm Dacron graft, and the left subclavian artery was reimplanted to the prosthesis with an 8-mm Dacron graft interposition. This aneurysm was the result of abnormal organogenesis of a primitive aortic arch and the remnant of the dorsal aorta, in other words, Kommerell's diverticulum. Microscopic examination demonstrated severe medial layer atrophy. In the light of the high risk of rupture, which was proved to be present by the very thin aneurysm wall at the time of surgery, we suggest early surgical treatment of idiopathic isthmus aneurysms in young patients regardless of aneurysm diameter.

The survival rates of boys and men with cancer have increased due to advances in cancer treatments; however, maintenance of quality of life, including fertility preservation, remains a major issue. Fertile male patients who receive radiation and/or chemotherapy face temporary, long-term, or permanent gonadal damage, particularly with exposure to alkylating agents and whole-body irradiation, which sometimes induce critical germ cell damage. These cytotoxic treatments have a significant impact on a patient's ability to have their own biological offspring, which is of particular concern to cancer patients of reproductive age. Therefore, various strategies are needed in order to preserve male fertility. Sperm cryopreservation is an effective method for preserving spermatozoa. Advances have also been achieved in pre-pubertal germ cell storage and research to generate differentiated male germ cells from various types of stem cells, including embryonic stem cells, induced pluripotent stem cells, and spermatogonial stem cells. These approaches offer hope to many patients in whom germ cell loss is associated with sterility, but are still experimental and preliminary. This review examines the current understanding of the effects of chemotherapy and radiation on male fertility.

BACKGROUND/AIMS: The interaction between nonsteroidal anti-inflammatory drugs (NSAIDs) and Helicobacter pylori remains controversial. We retrospectively investigated whether H. pylori infection exacerbates severe gastric mucosal injury among chronic NSAID users. METHODS: From January 2010 to December 2013, a total of 245 long-term NSAID (including low-dose aspirin) users who had undergone an esophagogastroduodenoscopy and had been evaluated for H. pylori infection were enrolled at Okayama University Hospital and Tsuyama Chuo Hospital. The degree of gastric mucosal injury was assessed according to the modified Lanza score (MLS). Severe gastric mucosal injury was defined as an MLS > or =4. Univariate and multivariate logistic regression analyses were performed. RESULTS: In the univariate analysis, age > or =75 years (odds ratio [OR], 2.4; 95% confidence interval [CI], 1.3 to 4.2), H. pylori-positivity (OR, 2.0; 95% CI, 1.2 to 3.5), and the concomitant use of proton pump inhibitors (PPIs) (OR, 0.48; 95% CI, 0.26 to 0.86) were significantly associated with severe gastric mucosal injury. The multivariate analysis was adjusted by age and sex and demonstrated that H. pylori-positivity (OR, 1.8; 95% CI, 1.0 to 3.3) and the concomitant use of PPIs (OR, 0.53; 95% CI, 0.28 to 0.99) significantly contributed to severe gastric mucosal injury. CONCLUSIONS: H. pylori infection exacerbates severe gastric mucosal injury among chronic NSAID users.

For the purpose of investigating weights in the era when the Shan Han Lun was set forth, the weight and measures described in the Ben Cao Jing Ji Zhu, written in the period slightly after the Shan Han Lun, were studied. Some descriptions of the metrological standards are confusing in the Ben Cao Jing Ji Zhu. We focused on the measuring container, whose volume is equal to that of the one cun square spoon (fang cun bi), shown in the dun huang version of the Ben Cao Jing Ji Zhu. The volume of this measuring container was calculated on the assumption that the measures in this text follow those of the Han Shu Li Li Shi, and a result of 5.07 cm3 was obtained. The result was confirmed by using the actual measured values of the crude drugs. The result was also considered to support measurements of the volume in the Ben Cao Jing Ji Zhu as following the Han Shu Li Li Shi. With those results, descriptions of the density of honey and lard were examined, and the weight in the Ben Cao Jing Ji Zhu was clarified to follow that in the Han Shu Li Li Shi.

The dosage of crude drugs described in the Shanghanlun has long been discussed, and a conversion ratio for 1 liang in the Songban Shanghanlun into modern grams has not been established yet. Ekisai Kariya, a bibliologist in Edo period Japan, claimed that the formulas in the Songban Shanghanlun could not be decocted when weighed with the “Han shu (lu li zhi)” scale (1 liang = 14 g, “regular scale”), and the weight scale in the text should be “Scale of Shen nong” (1/10 scale of the regular scale). This claim leads to the standards for Kampo prescription dosages. We inspected this matter by focusing on the amount of liquid absorbed by decoction residues, and demonstrated that the formulas in Songban Shanghanlun could actually be decocted when weighed with the “regular scale”. In addition, we calculated the quantities of Ephedra-alkaloids in the one-time dose of “Ma huang tang” of the several books written in the Song period, and the Songban Shanghanlun text, with results showing that Chinese doctors in the Song period recognized 1 liang in the Songban Shanghanlun as 14 grams in modern terms, and that the “regular scale” could be applied clinically. This strongly suggests that the metrological standard in the Songban Shanghanlun should be the “regular scale”.

BACKGROUND/AIMS: This study aimed to identify the predictive factors for inaccurate endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) diagnosis of swollen lymph nodes without rapid on-site cytopathological evaluation. METHODS: Eighty-three consecutive patients who underwent EUS-FNA for abdominal or mediastinal lymph nodes from January 2008 to June 2017 were included from a prospectively maintained EUS-FNA database and retrospectively reviewed. The sensitivity, specificity, and accuracy of EUS-FNA for the detection of neoplastic diseases were calculated. Candidate factors for inaccurate diagnosis (lymph node size and location, needle type, puncture route, number of passes, and causative disease) were evaluated by comparison between accurately diagnosed cases and others. RESULTS: The final diagnosis of the punctured lymph node was classified as neoplastic (65 cases: a metastatic lymph node, malignant lymphoma, or Crow-Fukase syndrome) or non-neoplastic (18 cases: a reactive node or amyloidosis). The sensitivity, specificity, and accuracy were 83%, 94%, and 86%, respectively. On multivariate analyses, small size of the lymph node was the sole predictive factor for inaccurate EUS-FNA diagnosis with a significant difference (odds ratios, 19.8; 95% confidence intervals, 3.15–124; p=0.0015). CONCLUSIONS: The lymph node size of <16 mm was the only independent factor associated with inaccurate EUS-FNA diagnosis of swollen lymph nodes.

BACKGROUND/AIMS: In this study, we aimed to evaluate the predictive value of localized stenosis of the main pancreatic duct (MPD) for early detection of pancreatic cancer.METHODS: Among 689 patients who underwent endoscopic retrograde pancreatography from January 2008 to September 2018, 19 patients with MPD findings were enrolled. These patients showed findings for indicating suspicious pancreatic cancer at an early stage (FiCE); FiCE was defined as a single, localized stenosis in the MPD without a detectable mass (using any other imaging methods) and without other pancreatic diseases, such as definite chronic pancreatitis, intraductal papillary mucinous neoplasm, and autoimmune pancreatitis. Final diagnoses were established by examining resected specimens or through follow-up examinations after an interval of >5 years.RESULTS: Among 19 patients with FiCE, 11 underwent surgical resection and 8 were evaluated after a >5-year observation period. The final diagnosis of the MPD stenosis was judged to be pancreatic cancer in 9 patients (47%), including 3 with intraepithelial cancer, and to be a non-neoplastic change in 10. The sensitivity, specificity, and accuracy of preoperative pancreatic juice cytology were 75%, 100%, and 88%, respectively.CONCLUSIONS: The predictive value of FiCE for pancreatic cancer prevalence was 47%. Histological confirmation with pancreatic juice cytology is necessary before surgical resection.

Objectives:
Diagnosis and treatment of osteoporosis are instrumental in obtaining good outcomes of hip surgery.Measuring bone mineral density (BMD) using dual-energy X-ray absorptiometry (DXA) is the gold standard for diagnosing osteoporosis. However, due to limited access to DXA, there is a need for a screening tool to identify patients at a higher risk of osteoporosis. We analyzed the potential utility of the Osteoporosis Self-assessment Tool for Asians (OSTA) as a screening tool for osteoporosis.
Methods:
A total of 1378 female patients who underwent hip surgery at 8 institutions were analyzed. For each patient, the BMD of the proximal femoral region was measured by DXA (DXA-BMD), and the correlation with OSTA score (as a continuous variable) was assessed. Receiver operating characteristic (ROC) curve analysis was performed to assess the ability of OSTA score to predict osteoporosis. Lastly, the OSTA score was truncated to yield an integer (OSTA index) to clarify the percentage of patients with osteoporosis for each index.
Results:
DXA-BMD showed a strong correlation with OSTA (r = 0.683; P < 0.001). On ROC curve analysis, the optimal OSTA score cut-off value of − 5.4 was associated with 73.8% sensitivity and 80.9% specificity for diagnosis of osteoporosis (area under the curve: 0.842). A decrease in the OSTA index by 1 unit was associated with a 7.3% increase in the probability of osteoporosis.
Conclusions
OSTA is a potentially useful tool for screening osteoporosis in patients undergoing hip surgery. Our findings may help identify high-risk patients who require further investigation using DXA.

Purpose:
Varicocele is a common problem among infertile men. Varicocele repair (VR) is frequently performed to improve semen parameters and the chances of pregnancy. However, there is a lack of consensus about the diagnosis, indications for VR and its outcomes. The aim of this study was to explore global practice patterns on the management of varicocele in the context of male infertility.
Materials and Methods:
Sixty practicing urologists/andrologists from 23 countries contributed 382 multiple-choice-questions pertaining to varicocele management. These were condensed into an online questionnaire that was forwarded to clinicians involved in male infertility management through direct invitation. The results were analyzed for disagreement and agreement in practice patterns and, compared with the latest guidelines of international professional societies (American Urological Association [AUA], American Society for Reproductive Medicine [ASRM], and European Association of Urology [EAU]), and with evidence emerging from recent systematic reviews and meta-analyses. Additionally, an expert opinion on each topic was provided based on the consensus of 16 experts in the field.
Results:
The questionnaire was answered by 574 clinicians from 59 countries. The majority of respondents were urologists/ uro-andrologists. A wide diversity of opinion was seen in every aspect of varicocele diagnosis, indications for repair, choice of technique, management of sub-clinical varicocele and the role of VR in azoospermia. A significant proportion of the responses were at odds with the recommendations of AUA, ASRM, and EAU. A large number of clinical situations were identified where no guidelines are available.
Conclusions
This study is the largest global survey performed to date on the clinical management of varicocele for male infertility. It demonstrates: 1) a wide disagreement in the approach to varicocele management, 2) large gaps in the clinical practice guidelines from professional societies, and 3) the need for further studies on several aspects of varicocele management in infertile men.
