For intermediate- and high-risk nonmuscle invasive bladder cancer (NMIBC), intravesical Bacillus Calmette-Guérin (BCG) therapy is the standard adjuvant treatment following transurethral resection of bladder tumor. Although intravesical BCG therapy improves disease progression and bladder preservation in most patients, there are still a considerable number of BCG-unresponsive cases, for whom radical cystectomy (RC) is the recommended salvage treatment option. However, RC is associated with high morbidity and mortality rates, and alternative treatment options are needed. New approaches, such as intravesical chemotherapy, device-assisted treatments, immune checkpoint inhibitors, viral gene therapy, antibody-drug conjugates, fibroblast growth factor receptor inhibitors, and other novel agents are being investigated. This review aims to provide an overview of the recent trials for BCG-unresponsive NMIBC.

Background:
The advance in microsurgical technique has facilitated a proper approach for reconstruction of extensive head and neck defects. For the success of free tissue reconstruction, selection of the recipient vessel is one of the most important factors. However, the vascular anatomy of this region is very complex, and a clear guideline about this subject is still lacking. In this study, we present our 30 years of experiences of free tissue reconstruction for head and neck defects.
Methods:
In this retrospective study, we analyzed a total of 138 flaps in 127 patients who underwent head and neck reconstruction using free tissue transfer following tumor resection between October 1986 to August 2019. Patients who underwent facial palsy reconstruction were excluded. Medical records including patient’s demographics, detailed operation notes, follow-up records, and photographs were collected and analyzed.
Results:
Among a total of 127 patients, 10 patients underwent a secondary operation due to cancer recurrence. The most commonly used type of flap was radial forearm flap (n= 107), followed by the anterolateral thigh flap (n= 18) and fibula flap (n= 10). With regard to recipient vessels, superior thyroid artery was most commonly used in arterial anastomosis (58.7%), and internal jugular vein (51.3%) was the first choice for venous anastomosis. The flap survival rate was 100%. Four cases of venous thrombosis were resolved with thrombectomy and re-anastomosis.
Conclusion
Superior thyroid artery and internal jugular vein were reliable choices as recipient vessels. Proper recipient vessel selection could improve the result of head and neck reconstruction.

Toxoplasma gondii is an intracellular protozoan parasite that infects approximately one third of the human popu- lation worldwide. Considering the toxicity and side effects of anti-toxoplasma medications, it is important to develop effec- tive drug alternatives with fewer and less severe off-target effects. In this study, we found that 4-hydroxybenzaldehyde (4- HBA) induced autophagy and the expression of NAD-dependent protein deacetylase sirtuin-1 (SIRT1) in primary murine bone marrow-derived macrophages (BMDMs). Interestingly, treatment of BMDMs with 4-HBA significantly reduced the number of macrophages infected with T. gondii and the proliferation of T. gondii in infected cells. This effect was impaired by pretreating the macrophages with 3-methyladenine or wortmannin (selective autophagy inhibitors) or with sirtinol or EX527 (SIRT1 inhibitors). Moreover, we found that pharmacological inhibition of SIRT1 prevented 4-HBA-mediated expres- sion of LC3-phosphatidylethanolamine conjugate (LC3-II) and the colocalization of T. gondii parasitophorous vacuoles with autophagosomes in BMDMs. These data suggest that 4-HBA promotes antiparasitic host responses by activating SIRT1- mediated autophagy, and 4-HBA might be a promising therapeutic alternative for the treatment of toxoplasmosis.

BACKGROUND: The aim of this study was to compare the clinical properties of sevoflurane-N2O-alfentanil with propofol- remifentanil anesthesia for patients undergoing laryngeal microscopic surgery. METHODS: Sixty patients scheduled for elective ambulatory surgery received either total intravenous anesthesia (TIVA group) with remifentanil and propofol or balanced anesthesia with sevoflurane-N2O-alfentanil (sevoflurane-N2O-alfentanil group). The TIVA group patients were induced with an effective-site concentration of 4microgram/ml propofol and a bolus dose of 0.5microgram/ml remifentanil. The anesthesia was maintained with a continuous infusions with an effective-site concentration of 2-5microgram/kg propofol and 0.05-0.5microgram/kg/min remifentanil, according to the hemodynamic response. The sevoflurane-N2O-alfentanil group patients were induced with 5 mg/kg thiopental and 20microgram/kg IV alfentanil. Maintenance was obtained with 1.5-3.0 vol% sevoflurane and a bolus dose of 10microgram/kg IV alfentanil if needed. The anesthetic depth was controlled under bispectral index (BIS) monitoring: propofol and sevoflurane concentrations were adjusted to achieve target BIS values, and were between levels of 40-60 during surgery. RESULTS: Both anesthetic methods provided acceptable hemodynamic responses during surgery. The late recovery times (postanesthetic discharge scoring system), patient satisfaction and postoperative side effects were similar between patients in the two groups. Early recovery times (eye opening and the aldrete score) were shorter in the TIVA group patients, but this difference was not associated with a shorter hospital length of stay. CONCLUSIONS: Total intravenous anesthesia with remifentanil-propofol and balanced anesthesia with sevoflurane-N2O-alfentanil both provided satisfactory anesthesia for laryngeal microscopic surgeryd

PURPOSE: The prevalence of asthma and obesity is increasing concomitantly, but the link between asthma and obesity is unclear. We sought to address possible roles of leptin and adiponectin in the development of asthma, and changes in pulmonary function in overweight children. METHODS: Four study groups of 61 children aged 6 to 18 years (mean age, 9.69+/-2.16) were enrolled: (1) 14 mild-to-moderate asthmatics with overweight, (2) 16 mild-to-moderate asthmatics with normal weight, (3) 16 obese subjects without asthma, and (4) 15 healthy controls. We measured biomarkers in blood, including total and allergen-specific IgE, eosinophil, eosinophilc cationic protein (ECP), leptin, adiponectin, interleukin (IL)-6, tumor necrosis factor-alpha (TNF-alpha), lipid profiles, insulin-like growth factor-1 (IGF-1) and insulin-like growth factor binding protein 3 (IGF-BP3). Body mass index (BMI), antioxidants and micronutrients in a daily diet were evaluated by the questionnaire. We performed the bronchial challenge test by methacholine inhalation and free running, respectively. RESULTS: The leptin levels was apparently high, and the adiponectin level was low in the over-weight children, as depicting a significant inverse correlation between the 2 variables (R=-0.479; P<0.001). The FEV(1)/FVC ratio was low in the overweight children regardless of the presence of asthma. However, the effect of IL-6, TNF-alpha, nutrients, and other variables on asthma development in the overweight children with asthma was not verified. CONCLUSION: In this study, the levels of leptin, adiponectin or other obesity-related biomarkers were not independently associated with asthma. Therefore, it is concluded that obesity may not be an important factor in pulmonary function impairment.

Leukocytoclastic vasculitis is a small vessel inflammatory disease mediated mostly by deposition of immune complexes. Etanercept (Enbrel(R)) is widely used not only for rheumatic disorders such as ankylosing spondylitis but also for dermatological diseases including psoriasis. Adverse drug reactions including pruritus, angioedema, and skin cancer have been reported. A 35-year-old female presented with palpable purpuric patches that developed on both lower legs 10 months after etanercept administration. A skin biopsy showed characteristic features of leukocytoclastic vasculitis, including perivascular infiltration of neutrophils and lymphocytes with leukocytoclasia and fibrinoid necrosis of the vessel wall. The patient was treated with oral and topical steroids, and the response was excellent and rapid. The patient was administered etanercept to control underlying ankylosing spondylitis. The skin lesions disappeared gradually after 4 weeks, and no other lesions were seen. The number of patients using etanercept has been increasing thus, the possibility of leukocytoclastic vasculitis in patients using etanercept should be considered.
