BACKGROUND The effect of radical hysterectomy for patients with cervical cancer on voiding function remains controversial. The purpose of this study was to examine the association between radical hysterectomy for patients with cervical cancer and the odds of developing neurogenic bladder by using data from the National Health Insurance Research Database (NHIRD) in Taiwan. METHODS We identified 17 936 patients who underwent radical hysterectomy for cervical cancer between 2000 and 2013 among inpatients registered in the Longitudinal Health Insurance Database in Taiwan. Of the patients, those diagnosed as having cervical cancer without radical hysterectomy were selected and compared as a matched control group. Patients diagnosed as having cervical cancer before the index date, those with neurogenic bladder dysfunction before tracking, and those aged

Background: Urothelial carcinoma ranks as the fourth most common cancer in men in the U.S; upon diagnosis, 10–15% have metastasized, mostly to lymph nodes, liver, lung, bone, and adrenal glands. Very few cases of skull invasion have been reported, and there is no established definite treatment. Case presentation: A 64-year-old Taiwanese male presented with metastatic urothelial carcinoma (mUC) of bladder with skull invasion. A sunken forehead without painful sensation could be palpated. After failure of chemotherapy, the patient received immunotherapy pembrolizumab, and complete remission of distant metastasis with reossification of osteolytic skull were noted. Conclusion: Immunotherapy has been reported to show significant remission in mUC, but mostly in solid organs or bone. While skull metastasis usually suggests late progression of the disease, immunotherapy has fewer systemic adverse effects than chemotherapy, and should be taken into consideration as a first-line therapy.

Background: Endoscopic combined intrarenal surgery (ECIRS) adds ureteroscopic vision to percutaneous nephrolithotomy (PCNL), which can be helpful when dealing with complex renal stones. Yet, there is still no consensus on the superiority of ECIRS. We aimed to critically analyze the available evidence of studies comparing efficacy, safety, bleeding risk, and efficiency of ECIRS and PCNL. Methods: We searched for studies comparing efficacy (initial and final stone-free rate), safety (postoperative fever, overall and severe complications), efficiency (operative time and hospital stay) and bleeding risk between ECIRS and PCNL. Meta-analysis was performed. Results: Seven studies (919 patients) were identified. ECIRS provided a significantly higher initial stone-free rate, higher final stone-free rate, lower overall complications, lower severe complications, and lower rate of requiring blood transfusion. There was no difference between the two groups in terms of postoperative fever, hemoglobin drop, operative time, and hospital stay. In the subgroup analysis, both minimally invasive and conventional ECIRS were associated with a higher stone-free rate and lower complication outcomes. Conclusions: When treating complex renal stones, ECIRS has a better stone-free rate, fewer complications, and requires fewer blood transfusions compared with PCNL. Subgroups either with minimally invasive or conventional intervention showed a consistent trend.

Background: In this study, we aimed to identify the association between chronic periodontal disease (CPD) and erectile dysfunction (ED) in a large young population. Patients and Methods: Totally 2191 male participants aged 18–28 years attended the Army Training Center in Taiwan between August 2012 and May 2013. All 1932 included participants filled in the International Index of Erectile Function-5 (IIEF-5) questionnaire and received a comprehensive dental examination to classify whether CPD. Results: There was a statistically significant correlation between the presence of ED and CPD (P < 0.001). Multivariate logistic regression analysis indicated that men with CPD were 1.6 (95% confidence interval = 1.280–2.009, P < 0.001) times more likely to have ED than men without CPD after adjusting confounders. Conclusion: This study demonstrates a link between ED and CPD, and it may be attributed to a combination of psychogenic and organic etiologies, such as systemic inflammation, oxidative stress, and endothelial dysfunction. This study highlights the significance of oral health, which may take a role in sexual function, even in young males. In clinical practice, more comprehensive management strategies to address participants with ED and CPD need to be investigated.

Objective To present a rare case of life-threatening postpartum hemorrhage due to uterine atony complicated by acute myocardial infarction and ischemic hepatitis. Case Report A 37-year-old parturient, gravida 1 para 0, presented with symptoms and signs of shock due to postpartum hemorrhage after delivery. Ischemic hepatitis, pulmonary edema, and adult respiratory distress syndrome developed the following morning. On the 7 th postpartum day, she developed chest pain and was subsequently diagnosed with acute inferior myocardial infarction based on serial changes on the electrocardiogram (ECG) and myocardial enzymes. The clinical condition improved after a series of resuscitative efforts and percutaneous transluminal coronary angioplasty. Conclusion The presented case demonstrated that when hypovolemic shock develops with complications of pulmonary edema or ischemic hepatitis, the possibility of cardiovascular disease should be immediately investigated and preventive measures initiated.

Rationale: Extracorporeal membrane oxygenation (ECMO) can deliver effective respiratory and circulatory maintenance to organ donors, improve organ function, and shorten warm ischemic time before harvesting. However, ECMO-supported brain-dead donors (DBDs) still have a high risk of acute kidney injury related to decreased renal oxygen delivery and inflammatory damage, which may cause early graft failure. Patient concerns: Kidney transplantation from an ECMO-supported DBD. Diagnoses: We found an extremely abnormal “very dark blue” appearance of the graft kidneys from an ECMO-supported DBD during kidney procurement. Interventions: Rather than discarding the graft kidneys, we performed an on-table biopsy. Pretransplant biopsy results revealed minimal interstitial fibrosis in the section of these graft kidneys. Outcomes: Two candidates received graft kidneys, and the two grafts remained functional until the 8-month follow-up. Lessons: Currently, there is no standard method for evaluating graft kidney function of ECMO-supported DBDs. Regardless of the donors’ preoperative serum creatinine (SCr) level, estimated glomerular filtration rate (eGFR), or gross appearance of the graft kidney, we believe that it is more reliable to include pretransplant biopsy as a criterion in clinical practice to safely accept kidneys from ECMO-supported DBDs.

PEG-modified gold nanoparticles (PEG-modified GNs) with diameters of 40 nm and 70 nm were prepared to elucidate the effect of extent of PEG (M.W. 5000) grafting and particle size on tumor accumulation and cellular uptake. Flow cytometry reveals that cellular uptake is strongly related to the size of PEG-modified GNs, rather than the extent of PEG-5K grafting level. Cytotoxicity analysis based on the intracellular release of drugs showed that the 70 nm PEG-modified GNs have the higher cytotoxicity, beccause of their greater cellular uptake. Also, particle size, rather than PEG-5K grafting level affects tumor accumulation. However, PEG-5K grafting level significantly affects the accumulation of particles in the liver and spleen. This finding is important in determining the proper PEG-5K grafting level and particle size for designing nano-medicines.

The presentation of disseminated peritoneal leiomyomatosis (DPL) can be misleading. Herein, we present the case of a 42-year-old nulliparous female who had previously undergone a total hysterectomy and presented with an acute abdomen. A presumptive diagnosis of ovarian torsion was made based on the clinical findings and an ultrasonographic examination. A diagnostic laparoscopy was performed immediately. DPL was subsequently diagnosed based on an intra-operative frozen section during surgical exploration and the final histopathologic examination. This case illustrates an atypical presentation of DPL mimicking ovarian torsion.
