Its incidence is on the rise, which is probably related to the increasing use of prostate biopsies to investigate patients with elevated serum prostate-specific antigen levels. Here, we report seven cases of incidental SV amyloidosis over a 3-year period and consider their relationship to the previously suggested aetiological factors. Based on our series, we conclude that incidental localized SV amyloidosis observed in diagnostic prostate biopsies does not warrant formal investigations for systemic amyloidosis.展开更多

Recent reports have indicated that a 3-dimensional(3D) reconstructed imaging system would be useful for understanding the liver anatomy before surgery. We have investigated a novel method that fuses MDCT and MRCP images. This novel system easily made it possible to detect the anatomical relationship between the vessels and bile duct in the portal hepatis. In this report, we describe a very rare case of extrahepatic cholangiocarcinoma associated with an accessory bile duct from the caudate lobe connecting with the intrapancreatic bile duct. We were unable to preoperatively detect this accessory bile duct using MDCT and MRCP. However, prior to the second operation, we were able to clearly visualise the injured accessory bile duct using our novel 3D imaging modality. In thisreport, we suggest that this imaging technique can be considered a novel and useful modality for understanding the anatomy of the portal hepatis, including the hilar bile duct.展开更多

The aim of this study was to evaluate the ultrasound （US） features of patients with MAGI and acquired premature ejaculation （APE） associated （MAGI-APEpos）. US evaluation of 50 MAGI-APEpos patients compared to 50 patients with MAGI without PE （MAGI-PEneg） which represent the control group. The diagnosis of APE was made through the evaluation of Intravaginal ejaculation latency time （IELT） and confirmed with the questionnaire PEDT （Premature Ejaculation Diagnostic Tool）. The main outcome measure was represented by the frequency of US criteria suggestive of P （prostatitis）, V （vesiculitis）, and E （epididymitis） in MAGI-APEpos and MAGI-PEneg patients. MAGI-APEpos patients showed a total number of US criteria significantly higher compared to MAGI-PEneg patients. MAGI-APEpos showed a higher frequency of US criteria of V and E （complicated forms of MAGI）. Finally, in MAGI-APEpos group, it was found a positive relationship between the anteroposterior diameter （APD） of the caudal tract of the epididymis and the APD of the seminal vesicles, as well as between both diameters and the PEDT score. MAGI-APEpos patients have a peculiar US characterization compared to MAGI-PEneg patients. According to these results, US evaluation of the epididymal and of the prostato vesicular tract should be considered in the practical clinical approach of patients with MAGI and APE. In particular, it could be a SUDDort for a possible Dathoahysiological interpretation of this clinical problem in these patients.展开更多

In previous studies, we have demonstrated that diabetic autonomic neuropathy （DAN） is associated with a peculiar ultrasound characterization of the seminal vesicles （SVs） in DM2 patients. The aim of the present study was to evaluate the frequency of MAGI in two different categories of DM2 patients （i.e. patients with and without symptoms that possibly reflect DAN） and the respective ultrasound characterizations. Sixty DM2 patients with a mean （± s.e.m.） age of 42.0 ± 6.0 years （range： 34-47 years） were classified according to the presence or the absence of symptoms that could possibly reflect DAN （group A： DM2 with symptoms possibly reflecting DAN, n = 28 patients and group B： DM2 without symptoms possibly reflecting DAN, n = 32 patients）. The patients in Group A exhibited a significantly higher frequency of MAGI compared with those in group B patients （P 〈 0.05）; moreover, the Group A patients exhibited a significantly higher frequency of ultrasound signs suggestive of vesiculitis （P 〈 0.05）. Finally, the concentrations of lymphocytes but not the concentrations of the leukocytes in the semen were significantly higher （P 〈 0.05） in group A compared with group B.展开更多

Methods： Thirty male rats were divided into five groups： group 1 （untreated） and groups 2, 3, 4 and 5 were fed for 30 days with 5%, 10%, 15% and 30% crude garlic, respectively. Testes and accessory organs were weighed and some markers were assessed. Light and electron microscopy observations were also performed. Results： A significant decrease was observed in the body weight of groups 4 （14%; P 〈 0.01） and 5 （20%; P 〈 0.01）; of the prostate weight in group 5 （29.1%; P 〈 0.05） and of seminal vesicle weight in groups 3 （14.4%; P 〈 0.01）, 4 （18.3%; P 〈 0.01） and 5 （27.3%; P 〈 0.01）. In contrast, testis and epididymis weights were unchanged. In epididymis tissue, the alpha glucosidase activity and the spermatozoa density were unchanged. The treatment resulted in a significant decrease in testosterone serum levels in groups 3 （77.3%; P 〈 0.01）, 4 （77.3%; P 〈 0.01） and 5 （90.9%; P 〈 0.01）, associated with a significant increase in LH serum levels （P 〈 0.01）. Testicular histology showed a dose-dependent increase in the percentage of empty seminiferous tubules. Moreover, testicular function was affected; a significant decrease in phosphatase acid activity （P 〈 0.01） and testosterone （P 〈 0.05） contents were observed. Conclusion： Crude garlic consumption during 1 month reduced testosterone secretion and altered spermatogenesis at 10%, 15% and 30% doses.展开更多

文摘Middle East respiratory syndrome(MERS)is a viral respiratory disease caused by a de novo coronavirus—MERS-CoV—that is associated with high mortality.However,the mechanism by which MERS-CoV infects humans remains unclear.To date,there is no effective vaccine or antibody for human immunity and treatment,other than the safety and tolerability of the fully human polyclonal Immunoglobulin G(IgG)antibody(SAB-301)as a putative therapeutic agent specific for MERS.Although rapid diagnostic and public health measures are currently being implemented,new cases of MERS-CoV infection are still being reported.Therefore,various effective measures should be taken to prevent the serious impact of similar epidemics in the future.Further investigation of the epidemiology and pathogenesis of the virus,as well as the development of effective therapeutic and prophylactic anti-MERS-CoV infections,is necessary.For this purpose,detailed information on MERS-CoV proteins is needed.In this review,we describe the major structural and nonstructural proteins of MERS-CoV and summarize different potential strategies for limiting the outbreak of MERS-CoV.The combination of computational biology and virology can accelerate the advanced design and development of effective peptide therapeutics against MERS-CoV.In summary,this review provides important information about the progress of the elimination of MERS,from prevention to treatment.

We have investigated a novel method that fuses MDCT and MRCP images. This novel system easily made it possible to detect the anatomical relationship between the vessels and bile duct in the portal hepatis. In this report, we describe a very rare case of extrahepatic cholangiocarcinoma associated with an accessory bile duct from the caudate lobe connecting with the intrapancreatic bile duct. We were unable to preoperatively detect this accessory bile duct using MDCT and MRCP. However, prior to the second operation, we were able to clearly visualise the injured accessory bile duct using our novel 3D imaging modality. In thisreport, we suggest that this imaging technique can be considered a novel and useful modality for understanding the anatomy of the portal hepatis, including the hilar bile duct.
文摘We have previously demonstrated a high frequency of premature ejaculation （PE） among patients with male accessory gland infection （MAGI）. The aim of this study was to evaluate the ultrasound （US） features of patients with MAGI and acquired premature ejaculation （APE） associated （MAGI-APEpos）. US evaluation of 50 MAGI-APEpos patients compared to 50 patients with MAGI without PE （MAGI-PEneg） which represent the control group. The diagnosis of APE was made through the evaluation of Intravaginal ejaculation latency time （IELT） and confirmed with the questionnaire PEDT （Premature Ejaculation Diagnostic Tool）. The main outcome measure was represented by the frequency of US criteria suggestive of P （prostatitis）, V （vesiculitis）, and E （epididymitis） in MAGI-APEpos and MAGI-PEneg patients. MAGI-APEpos patients showed a total number of US criteria significantly higher compared to MAGI-PEneg patients. MAGI-APEpos showed a higher frequency of US criteria of V and E （complicated forms of MAGI）. Finally, in MAGI-APEpos group, it was found a positive relationship between the anteroposterior diameter （APD） of the caudal tract of the epididymis and the APD of the seminal vesicles, as well as between both diameters and the PEDT score. MAGI-APEpos patients have a peculiar US characterization compared to MAGI-PEneg patients. According to these results, US evaluation of the epididymal and of the prostato vesicular tract should be considered in the practical clinical approach of patients with MAGI and APE. In particular, it could be a SUDDort for a possible Dathoahysiological interpretation of this clinical problem in these patients.

文摘The development of accessory breast tissue,which is found anywhere along the milk line,is attributed to the failure of milk line remnants to regress during embryogenesis.Primary tumors may arise from any ectopic breast tissue.Accessory breast cancer occurring concurrently with primary invasive breast cancer is extremely rare.Two such cases were reported in this article.One was a 43-year-old Chinese female who exhibited bilateral breast cancer(invasive ductal carcinoma,not otherwise specified,IDC-NOS) and an accessory breast carcinoma(IDC-NOS) incidentally identified in her left axilla.The ectopic breast tissue in her right axilla presented with adenosis.The patient was surgically treated,followed by postoperative docetaxel epirubicin(TE) chemotherapy.The second case was a 53-year-old Chinese female with bilateral breast cancer(apocrine carcinoma) accompanied by an accessory breast carcinoma(IDC-NOS) in her right axilla that was also incidentally identified.The patient was surgically treated after three doses of cyclophosphamide epirubicin docetaxel(CET) neoadjuvant chemotherapy,followed by adjuvant chemotherapy of the same regimen.
文摘Male accessory gland inflammation or infection （MAGI） is a potentially underdiagnosed complication of type 2 diabetes （DM2）; specifically, we reported in a recent study that the frequency of MAGI was 43% among DM2 patients. In previous studies, we have demonstrated that diabetic autonomic neuropathy （DAN） is associated with a peculiar ultrasound characterization of the seminal vesicles （SVs） in DM2 patients. The aim of the present study was to evaluate the frequency of MAGI in two different categories of DM2 patients （i.e. patients with and without symptoms that possibly reflect DAN） and the respective ultrasound characterizations. Sixty DM2 patients with a mean （± s.e.m.） age of 42.0 ± 6.0 years （range： 34-47 years） were classified according to the presence or the absence of symptoms that could possibly reflect DAN （group A： DM2 with symptoms possibly reflecting DAN, n = 28 patients and group B： DM2 without symptoms possibly reflecting DAN, n = 32 patients）. The patients in Group A exhibited a significantly higher frequency of MAGI compared with those in group B patients （P 〈 0.05）; moreover, the Group A patients exhibited a significantly higher frequency of ultrasound signs suggestive of vesiculitis （P 〈 0.05）. Finally, the concentrations of lymphocytes but not the concentrations of the leukocytes in the semen were significantly higher （P 〈 0.05） in group A compared with group B.
文摘Aim： To investigate the effects of crude garlic on adult male rat reproductive functions. Methods： Thirty male rats were divided into five groups： group 1 （untreated） and groups 2, 3, 4 and 5 were fed for 30 days with 5%, 10%, 15% and 30% crude garlic, respectively. Testes and accessory organs were weighed and some markers were assessed. Light and electron microscopy observations were also performed. Results： A significant decrease was observed in the body weight of groups 4 （14%; P 〈 0.01） and 5 （20%; P 〈 0.01）; of the prostate weight in group 5 （29.1%; P 〈 0.05） and of seminal vesicle weight in groups 3 （14.4%; P 〈 0.01）, 4 （18.3%; P 〈 0.01） and 5 （27.3%; P 〈 0.01）. In contrast, testis and epididymis weights were unchanged. In epididymis tissue, the alpha glucosidase activity and the spermatozoa density were unchanged. The treatment resulted in a significant decrease in testosterone serum levels in groups 3 （77.3%; P 〈 0.01）, 4 （77.3%; P 〈 0.01） and 5 （90.9%; P 〈 0.01）, associated with a significant increase in LH serum levels （P 〈 0.01）. Testicular histology showed a dose-dependent increase in the percentage of empty seminiferous tubules. Moreover, testicular function was affected; a significant decrease in phosphatase acid activity （P 〈 0.01） and testosterone （P 〈 0.05） contents were observed. Conclusion： Crude garlic consumption during 1 month reduced testosterone secretion and altered spermatogenesis at 10%, 15% and 30% doses.

文摘Bile duct injuries(BDIs)are difficult to avoid absolutely when the biliary tract has a malformation,such as accessory hepatic duct.Here,we investigated the management strategies for BDI combined with accessory hepatic duct during laparoscopic cholecystectomy.
文摘BACKGROUND Accessory and cavitated uterine mass(ACUM)is an uncommon form of connate Müllerian anomaly seen in young and nulliparous women,which presents as chronic periodic pelvic pain and severe dysmenorrhea.The entity is often underdiagnosed due to a broad differential diagnosis,including rudimentary uterine horn,true cavitated adenomyosis and degenerating fibroids.CASE SUMMARY A 22-year-old woman who presented with severe dysmenorrhea and was initially misdiagnosed with cystic adenomyosis.Gynecological examination and ultrasonography were performed.The patient underwent laparoscopic excision of the mass and histopathological examination confirmed the diagnosis.Postoperatively,the patient did well,with no further dysmenorrhea.CONCLUSION ACUM is difficult to diagnose.A correct diagnosis can be made only after excision and histopathological evaluation.Surgical excision is necessary and can be carried out by laparoscopy.
