Two analogs of sildenafil (compounds 1 and 2) were detected in three powder products acquired from online drug markets during an LC-UV-MS analysis of psychotropic drugs. Their structures were established by high-resolution mass spectrometry and NMR spectroscopy. Compound 1 was identified as 5-(5-(3,5-dimethylpiperazine-1-carbonothioyl)-2-ethoxyphenyl)-1-methyl-3-propyl-1H-pyrazolo[4,3-d]pyrimidine-7(6H)-thione and named dimethyldithiodenafil.

Here we report a technique for the complete resection of locally advanced adenoid cystic carcinoma (ACC) of the Bartholin's gland that had invaded the obturator muscle and inferior pubic ramus.
Methods: We chose to operate because there was little evidence of definitive radiotherapy for ACC of the vulva.
Gastric leakage and stricture are challenging complications of sleeve gastrectomy (SG). Failure of endoscopic intervention necessitates revision surgery. We describe two cases in which proximal gastrectomy with double tract reconstruction (PG with DTR) was performed in patients with chronic gastric fistula and twisted gastric tube after SG.

Methods: Patients receiving curative surgical resection were centrally randomized to arm A (4 weeks of oral S-1 and a 2-week rest over 12 months) or arm B (2 weeks of S-1 and a 1-week rest over 12 months). The primary endpoints were completion of the scheduled adjuvant chemotherapy over 12 months, and the secondary endpoints were relative total administration dose, toxicity, and 3-year disease-free survival.
Working memory capacity, a critical component of executive function, expands developmentally from childhood through adulthood. Anomalies in this developmental process are seen in individuals with autism spectrum disorder (ASD), schizophrenia and intellectual disabilities (ID), implicating this atypical process in the trajectory of developmental neuropsychiatric disorders. However, the cellular and neuronal substrates underlying this process are not understood.

We investigated the effect of ventricular septal defect (VSD) enlargement on long-term surgical results, late arrhythmia, and left ventricular (LV) function in the Rastelli procedure for D-transposition of the great arteries with LV outflow tract obstruction (LVOTO). From 1979 to 2001, 74 patients (D-transposition of the great arteries, n = 56; double outlet right ventricle, n = 18) underwent the Rastelli procedure. In group A, 46 patients underwent the Rastelli procedure with VSD enlargement, and in group B, 28 patients underwent the Rastelli procedure without enlargement.

In the operation, a venting tube was inserted through the incised patent foramen ovale. The ventricular septal defect was closed using a patch and the incised patent foramen ovale was directly closed.

Methods: Between 1974 and 2010, 79 consecutive patients underwent the Fontan procedure at an age ≥ 15 years (mean age at Fontan operation, 20.
Background: Despite the widespread use of opioids for the treatment of cancer pain, results from several surveys consistently show that pain is still prevalent in some patients with malignant diseases. The purinergic P2Y12 receptor is a primary site leading to microglial activation and hyperalgesic pain behaviors and is considered a key regulator in the prevention of the aggravation of clinical pain conditions. Genetic variability in the P2RY12 gene may contribute to individual differences in pain and opioid sensitivity.

The cultured organism, however, is sometimes different among these samples.
Methods: Two hundred sixty patients with CIED infection, who underwent lead extraction between April 2005 and December 2014, were analyzed.
Objectives: To clarify whether weight change in patients with Parkinson's disease (PD) or progressive supranuclear palsy (PSP) is caused by the disease itself or secondarily by other factors.
Materials And Methods: We conducted a retrospective analysis of 51 patients with PD and 14 patients with PSP, especially during the early stage of their diseases. All patients were independent in terms of their activities of daily living and did not have any feeding difficulty.
Background: Data regarding long-term mortality and factors influencing appropriate therapies in Japanese patients with implantable cardioverter defibrillators (ICD), who satisfy the Multicenter Automatic Defibrillator Implantation Trial II (MADIT II) criteria for primary prevention, remain scarce.
Methods: A total of 118 consecutive patients who underwent ICD implantation without any prior ventricular arrhythmic event, from January 2000 to December 2012, were enrolled based on the MADIT II criteria: left ventricular ejection fraction (LVEF) of ≤30% with ischemic heart disease and at least 4 weeks after a myocardial infarction. We investigated the mortality and factors influencing appropriate ICD therapies in this population.
Purpose: To evaluate the effects of atrial natriuretic peptide (ANP) on renal function and medical costs in patients with acute kidney injury (AKI) associated with cardiac surgery.
Materials And Methods: The Japanese trial for AKI in Post-cardiovascular surgery patients by ANP (JAPAN) was a prospective, multicenter, randomized, double-blind, placebo-controlled study conducted in 11 hospitals in Japan. Acute kidney injury was defined as an increase in serum creatinine of at least 0.
Background: Catheter ablation can reduce episodes of ventricular tachycardia (VT) after myocardial infarction (MI). However, the optimal endpoint of the ablation procedure remains unclear.
Methods: Fifty-one consecutive patients who received catheter ablation for VT after MI were included.
The unilateral absence of a proximal pulmonary artery (UAPPA) is rare and is most frequently accompanied by cardiovascular anomalies such as tetralogy of Fallot or septal defects. We report a patient with truncus arteriosus with UAPPA in which we performed a two-stage surgical repair. During the first palliative operation, a right modified Blalock-Taussig shunt was constructed to develop the hypoplastic right pulmonary artery.

Methods: Between 1986 and 2006, 9 patients with dextro-transposition of the great arteries underwent ASO conversion at our institute. All patients had systemic right ventricle failure, 6 had supraventricular tachycardia, and 8 had moderate or severe tricuspid valve regurgitation.
Objectives: This study aimed to analyze long-term survival and functional outcomes after truncus arteriosus repair in a single institution with more than 40 years of follow-up.
Methods: Medical records were analyzed retrospectively in 52 patients who underwent the Rastelli procedure for truncus arteriosus repair between 1974 and 2002. Thirty-five patients survived the initial repair.
Unlabelled: While the prevalence of sudden infant death syndrome (SIDS) has decreased worldwide, this decline has plateaued recently. Strategies are needed to resume the constant decrease of SIDS in Japan. A prospective electrocardiographic screening program for infants was performed between July 2010 and March 2011.

Methods: A 51-year-old woman presented with ovarian cancer and isolated nodal recurrence located on the right side of the pelvis. As the tumor had infiltrated the EIV wall, we performed the EIV excision and reconstruction using an autogenous graft.
