Objective To assess the clinical diagnosis and treatment of 21-hydroxylase deficiency nonclassic congenital adrenal hyperplasia (NCCAH) complicated by testicular adrenal rest tumors (TART),thus to improve the recognition of the disease.Methods The clinical data of one patient of NCCAH with TART from our department in 2016 were retrospectively studied,and were analyzed combined with related literature,and the diagnosis was established for treatment.Results The patient was a 17 years old boy.At the age of seven began to appear the pubic hair,voice and other secondary sexual performance.More than their big penis development was significantly higher than their peers.At the age of 12 found bilateral testicular gradually enlarged and attendance.Physical examination:bilateral testicular swelling and a sense of nodules,hard texture,epididymis,normal bilateral varicocele.Laboratory exam indications showed increased levels of progesterone(P),adrenocorticotropic hormone(ACTH),17 hydroxyprogesterone(17α-OHP),aaldosterone(ALD),17-hydroxyl corticosteroids(17-OHCS),17-ketone corticosteroids(17-KS).By the ACTH stimulating test,17α-OHP was increased.Bilateral testes MRI:irregular bilateral testes,signal,see in space.Enhanced scan lesions uniform reinforcement,germ cell tumors to row.Adrenal CT:bilateral adrenal hyperplasia.Testicular biopsy:testicular adrenal genital syndrome tumor.Genetic testing:CYP21A2 heterozygous mutations.The above test results were diagnosed of NCCAH 21-OHD with TART.The patient was orally given 10mg/d prednisone 2 time.3 months after treatment,the 17α-OHP,CO and sex hormones returned to normal.Review the adrenal CT showed significant bilateral adrenal shrink,Pa/testis tubercle was narrow,but not obvious.Semen routine still suggested no sperm,considering the TART medical treatment effect was poor.Hence,further line tumor removed,followed up for 3 months without tumor recurrence at present.Conclusion NCCAH complex and varied clinical manifestations and hidden.Not easy to be noticed by patients and clinicians.For the early childhood in pubic hair growth accelerated leading to premature epiphyseal fusion and make the adult height is short stature consideration should be given to the disease.Further lines of sex hormones,adrenal related endocrine examination,genetic testing and ACTH stimulating test,etc.If concurrent bilateral testicular nodules,should consider to merge TART may.Testicular biopsy can be clear.Treatment can choose according to TART classification of glucocorticoid (a hormone steroid) or surgical treatment,concrete scheme should be individualized.

Objective To assess the clinical efficacy of ultrasonography guidance percutaneous nephrolithot-omyⅠ period combining pneumatic ultrasosonic and holmium laser lithotrips of complex renal calculi.Methods Patients were under the general anesthesia in lithotomy position.By cystoscope first to one side retrograde insertion F5 ureteral catheter,the position to prone position was changed.Under ultrasonography guidance puncture target after the success of the calyx,fascia dilator gradually expanded from F8 to F20 channel was established.Then percutaneous nephroscope combining pneumatic ultrasosonic and holmium laser lithotripsy were administrated.Results One sided single channel was 92 cases,one sided dual channel was 11 cases,one sided three -channel was 1 case.On both sides single channel was 13 cases,one side of the dual channel and other side of the single channel was 3 cases.The operation time was (72 ±24)min.Intraoperative bleeding was in 50 -150mL,with an average of 80mL,and there's no intraoper-ative blood transfusion.2 cases of postoperative had secondary bleeding,in which 1 case remitted after non -operative treatment,the other case was treated in DSA downward super selective renal artery embolization to stop the bleeding. Postoperative hospital stay was 7 -14d,with an average of 10d.There were no septic shock,water uptake,water intoxi-cationand complications such as pleural effusion.One week after the CT,stones free rate was 91.7%(110 /120),in which 10 cases of residual stone with diameter <5mm,needn't surgery removed again.They were treated with oral platoon stone drugs,drinking lots of water and a moderate amount of sports such as processing.All cases were followed up for 6 months to 18 months,with no urinary tract infection,stone recurrence and the long -term complications such as perinephric space effusion.Conclusion As long as establish proper percutaneous renal channel,with intraoperative operating norms,combining pneumatic ultrasosonic and holmium laser,ultrasonography guidance percutaneous nephro-lithotomy Ⅰ period clear renal calculi is completely can be done.And it can shorten operation time,and has clear renal calculi with high efficiency,small trauma and less long -term complications.It is safe and effective,and worthy of clinical popularization and application.

Objective:To compare the diagnostic efficacy of 68Ga-PSMA-11 PET/ CT and multi-parameter magnetic resonance imaging (mpMRI) for pelvic lymph node metastases in prostate cancer patients who received neoadjuvant endocrinology or not after initial diagnosis. Methods:Data of 52 patients with moderate and high-risk prostate cancer admitted to Xijing Hospital from February to October 2023, aged (65.8±6.6) years, preoperative prostate-specific antigen (PSA) 26.67 (13.09, 84.89) ng/ml, were retrospectively analyzed. Before operation, there were 28 cases of cT 2stage, 16 cases of cT 3 stage and 8 cases of cT 4 stage. There were 22 cases of cN 0 and 30 cases of cN 1. All patients underwent 68Ga-PSMA-11 PET/CT and mpMRI at the same time, and were diagnosed positive lymph nodes in 28 and 21 cases, respectively. Risk stratification were high risk in 45 cases, and medium risk in 7 cases. According to the preoperative endocrine treatment, they were divided into the newly diagnosed group without treatment (24 cases) and the endocrine treated group (28 cases), whose ages were (65.0±7.1) years and (66.8±6.1) years, respectively. Preoperative PSA was 26.17 (16.73, 61.18) ng/ml and 27.32 (11.94, 130.18) ng/ml, respectively. Gleason scores ≤7 were in 10 cases (41.7%) and 6 cases (21.4%), and Gleason scores >7 were in 14 cases (58.3%) and 22 cases (78.6%), respectively. There were 15 (62.5%) and 13 (46.4%) cases of cT 1-2 stage, and 9 (37.5%) and 15 (53.6%) cases of cT 3-4 stage, respectively. There were 16 (66.7%) and 6 (21.4%) cases of stage N 0, 8 (33.3%) and 22 (78.6%) cases of stage N 1, respectively. There were 22 (91.7%) and 20 (71.4%) cases of stage M 0, 2 (8.3%) and 8 (28.6%) cases of stage M 1, respectively. PET/CT diagnosis of lymph node positive was in 9 cases (37.5%) and 19 cases (67.9%), and mpMRI diagnosis of lymph node positive was in 5 cases (20.8%) and 16 cases (57.1%). The number of positive lymph nodes diagnosed by PET/CT was 13 (72.2%) and 47 (90.1%), and the number of positive lymph nodes diagnosed by mpMRI was 8 (44.4%) and 32 (61.5%). There was no significant difference ( P>0.05). All patients underwent radical prostatectomy as well as enlarged pelvic lymph node resection. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the two imaging examinations in the diagnosis of lymph node metastasis were compared according to the results of postoperative pathological examination of lymph nodes. Receiver operating characteristic (ROC) curve was used to compare the accuracy of the two imaging tests in the diagnosis of pelvic lymph node metastasis in the newly diagnosed untreated group and the endocrine treated group. Results:In this study, of 52 cases, 26 (50.0%) had positive lymph nodes by pathological examination. In this study, a total of 681 lymph nodes were dissected, with 70 lymph nodes (10.28%) being pathologically positive, and the positive rate of 26 patients was 17.99% (70/389). The PET/CT and mpMRI detection rates of 26 node-positive patients were 92.3% (24/26) and 57.7% (15/26), respectively. There were 9 (37.5%) and 17 (60.7%) lymph node positive patients in the untreated group and the endocrine therapy group, respectively. There were 320 and 361 lymph nodes were clear, with 18 (5.6%) and 52 (14.4%) positive lymph nodes, respectively. The detection rates of PET/CT and mpMRI were 88.89% (8/9) and 94.12% (16/17)in the untreated group, and 44.44% (4/9) and 64.71% (11/17)in the endocrine treated group, respectively. In the newly treated group, the area under the curve (AUC) of PET/CT and mpMRI for diagnosing positive lymph nodes were 0.911 and 0.689 ( P=0.027), the sensitivity were 88.9% and 44.4%, and the specificity were 93.3% and 93.3%, respectively. PPV were 88.9% and 80.0%, and NPV were 93.3% and 73.7%, respectively. In the endocrine therapy group, the AUC of PET/CT and mpMRI for lymph node positive diagnosis were 0.834 and 0.596 ( P=0.011), the sensitivity were 94.1% and 64.7%, the specificity were 72.7% and 54.5%, and the PPV were 84.2% and 68.8%, respectively. NPV were 88.9% and 50.0%, respectively. Conclusions:For prostate cancer patients, regardless of whether they receive neoadjuvant endocrine therapy, 68Ga-PSMA-11 PET/CT can accurately detect pelvic lymph node metastasis, and the diagnostic efficacy is significantly better than that of mpMRI.

Objective:We investigated the incidence of surgical site infection (SSI) following emergency abdominal surgery (EAS) in China and further explored its risk factors, providing a reference for preventing and controlling SSI after EAS.Methods:This was an observational study. Data of patients who had undergone EAS and been enrolled in the Chinese SSI Surveillance Program during 2018–2021were retrospectively analyzed. All included patients had been followed up for 30 days after surgery. The analyzed data consisted of relevant patient characteristics and perioperative clinical data, including preoperative hemoglobin, albumin, and blood glucose concentrations, American Society of Anesthesiologists (ASA) score, grade of surgical incision, intestinal preparation, skin preparation, location of surgical site, approach, and duration. The primary outcome was the incidence of SSI occurring within 30 days following EAS. SSI was defined as both superficial and deep incisional infections and organ/space infections, diagnoses being supported by results of microbiological culture of secretions and pus. Secondary outcomes included 30-day postoperative mortality rates, length of stay in the intensive care unit (ICU), duration of postoperative hospitalization, and associated costs. The patients were classified into two groups, SSI and non-SSI, based on whether an infection had been diagnosed. Univariate and multivariate logistic regression analyses were performed to identify risk factors associated with SSI following EAS.Results:The study cohort comprised 5491 patients who had undergone EAS, comprising 3169 male and 2322 female patients. SSIs were diagnosed in 168 (3.1%) patients after EAS (SSI group); thus, the non-SSI group consisted of 5323 patients. The SSIs comprised superficial incision infections in 69 (41.1%), deep incision infections in 51 (30.4%), and organ or space infections in 48 (28.6%). Cultures of secretions and pus were positive in 115 (68.5%) cases. The most frequently detected organism was Escherichia coli (47/115; 40.9%). There were no significant differences in sex or body mass index between the SSI and non-SSI groups (both P>0.05). However, the proportion of individuals aged 60 years or older was significantly greater in the SSI than in the non-SSI group (49.4% [83/168] vs. 27.5% [1464/5323), χ 2=38.604, P<0.001). Compared with the non-SSI group, the SSI group had greater proportions of patients with diabetes (11.9% [20/168] vs. 4.8% [258/5323], χ 2=16.878, P<0.001), hypertension (25.6% [43/168] vs. 12.2% [649/5323], χ 2=26.562, P<0.001); hemoglobin <110 g/L (27.4% [46/168] vs. 13.1% [697/5323], χ 2=28.411, P<0.001), and albuminemia <30 g/L (24.4% [41/168] vs. 5.9% [316/5323], χ 2=91.352, P<0.001), and a reduced rate of preoperative skin preparation (66.7% [112/168] vs. 75.9% [4039/5323], χ 2=7.491, P=0.006). Furthermore, fewer patients in the SSI group had preoperative ASA scores of between one and two (56.0% [94/168] vs. 88.7% [4724/5323], χ 2=162.869, P<0.001) in the non-SSI group. The incidences of contaminated and infected incisions were greater in the SSI group (63.1% [106/168] vs. 38.6% [2056/5323], χ 2=40.854, P<0.001). There was a significant difference in surgical site distribution between the SSI and non-SSI groups (small intestine 29.8% [50/168] vs. 10.6% [565/5323], colorectal 26.2% [44/168] vs. 5.6% [298/5 323], and appendix 24.4% [41/168] vs. 65.1% [3465/5323]) χ 2=167.897, P<0.001), respectively. There was a significantly lower proportion of laparoscope or robotic surgery in the non-SSI group (24.4 % [41/168] vs. 74.2% [3949/5323], χ 2=203.199, P<0.001); the percentage of operations of duration less than 2 hours was significantly lower in the SSI than non-SSI group (35.7% [60/168] vs. 77.4% [4119/5323], χ 2=155.487, P<0.001). As to clinical outcomes, there was a higher 30-day postoperative mortality rate (3.0%[5/168] vs. 0.2%[10/5323], χ 2=36.807, P<0.001) and higher postoperative ICU occupancy rate (41.7% [70/168] vs. 19.7% [1046/5323], χ 2=48.748, P<0.001) in the SSI group. The median length of stay in the ICU (0[2] vs. 0[0] days, U=328597.000, P<0.001), median total length of stay after surgery (16[13] vs. 6[5] days, U=128146.000, P<0.001), and median hospitalization cost (ten thousand yuan, 4.7[4.4] vs. 1.7[1.8], U=175965.000, P<0.001) were all significantly greater in the SSI group. Multivariate logistic regression analysis revealed that the absence of skin preparation before surgery (OR=2.435,95%CI: 1.690–3.508, P<0.001), preoperative albuminemia <30 g/L (OR=1.680, 95%CI: 1.081–2.610, P=0.021), contaminated or infected incisions (OR=3.031, 95%CI: 2.151–4.271, P<0.001), and laparotomy (OR=3.436, 95% CI: 2.123–5.564, P<0.001) were independent risk factors of SSI. Operative duration less than 2 hours (OR=0.465, 95%CI: 0.312–0.695, P<0.001) and ASA score of 1–2 (OR=0.416, 95% CI: 0.289–0.601, P<0.001) were identified as independent protective factors for SSI. Conclusions:It is important to consider the nutritional status in the perioperative period of patients undergoing EAS. Preoperative skin preparation should be conducted and, whenever possible, laparoscope or robot-assisted surgery. Duration of surgery should be as short as possible while maintaining surgery quality and improving patient care.
