The patient had a complete response to treatment endoscopically, 9months after the last administration of nivolumab. After that, there was no recurrence of the cancer, despite there being no treatment for 5months.
It was suggested that the therapeutic effect of nivolumab could be maintained for a long period after discontinuation of its administration. In addition, a correlation has been reported between the treatment efficacy and immune-related adverse events associated with nivolumab.
The synergistic effect of the sustained effect of nivolumab and later-line treatment may contribute to the prolongation of survival after discontinuation of nivolumab in patients who are refractory or intolerant to treatment.

A few studies have linked DWMA with microstructural abnormalities, but the exact relationship remains poorly understood. We related DWMA extent to graph theory measures of network efficiency at term in a representative cohort of 343 very preterm infants. We performed anatomic and diffusion MRI at term and quantified DWMA volume with our novel, semi-automated algorithm. HG-9-91-01 chemical structure From diffusion-weighted structural connectomes, we calculated the graph theory metrics local efficiency and clustering coefficient, which measure the ability of groups of nodes to perform specialized processing, and global efficiency, which assesses the ability of brain regions to efficiently combine information. We computed partial correlations between these measures and DWMA volume, adjusted for confounders. Increasing DWMA volume was associated with decreased global efficiency of the entire very preterm brain and decreased local efficiency and clustering coefficient in a variety of regions supporting cognitive, linguistic, and motor function. We show that DWMA is associated with widespread decreased brain network efficiency, suggesting that it is pathologic and likely has adverse developmental consequences.
Inflatable penile prostheses (IPP) consist of 2 cylinders implanted into the corpora cavernosa, a pump placed in the scrotum, and a saline-filled reservoir traditionally placed in the space of Retzius. IPPs are used to treat refractory erectile dysfunction with few rare, but serious, complications. Cases of reservoirs causing erosion into the bladder, small bowel obstructions, vascular compression, and inguinal herniation have been described.
We highlight the importance of keeping a broad differential diagnosis when assessing patients with bowel obstructions.
A 68-year-old man with a previous IPP placement presented with left lower quadrant abdominal pain, constipation and obstipation for 5 days. On exam, he was afebrile, and noted to have a firm, distended, tympanic abdomen. CT scan showed a distended cecum at 11 cm, narrowing of the proximal sigmoid with adjacent inflammatory changes, and minimal peri-colonic air, suggestive of a localized perforation. The IPP reservoir was seen in the left iliac fossA, etal. A Case Report of Large Bowel Obstruction in a Patient With an Inflatable Penile Prosthesis. Sex Med 2021;9100391.
Although complications related to IPPs, including bowel obstructions, have been previously described in the literature, treatment for large bowel obstructions must take into account all possible etiologies, including malignancy.

We performed a review of the literature on clinical presentation of homozygous HD cases and highlight that, so far, evidence exists that HD is a truly dominant disorder. This has important implications for pathophysiology concepts of the disease.
Patients with ideomotor apraxia (IMA) present with selective impairments in higher-order motor cognition and execution without damage to any motor or sensory pathways. Although extensive research has been conducted to determine the regions of interest (ROIs) underlying these unique impairments, previous models are heterogeneous and may be further clarified based on their structural connectivity, which has been far less described.
The goal of this research is to propose an anatomically concise network model for the neurophysiologic basis of IMA, specific to the voluntary pantomime, imitation and tool execution, based on intrinsic white matter connectivity.
We utilized meta-analytic software to identify relevant ROIs in ideomotor apraxia as reported in the literature based on functional neuroimaging data with healthy participants. After generating an activation likelihood estimation (ALE) of relevant ROIs, cortical parcellations overlapping the ALE were used to construct an anatomically precise model of aification is necessary with voxel-based lesion studies of IMA to further refine these findings.
We constructed a preliminary model demonstrating the underlying structural interconnectedness of anatomic substrates involved in higher-order motor functioning which is seen impaired in IMA. Our model provides support for previous dual-stream processing frameworks discussed in the literature, but further clarification is necessary with voxel-based lesion studies of IMA to further refine these findings.
We aimed to determine whether fecal microbiota transplant (FMT) is safe and possibly efficacious in treating constipation, motor, and non-motor symptoms in Parkinson’s disease (PD) patients.
Patients with PD, constipation and an indication for screening colonoscopy were treated with FMT. The study was conducted from December 2017 to November 2019, and clinical outcomes assessing motor, non-motor and constipation symptoms were compared at baseline (week 0) and at 2, 4, 8, 12, 16, 20, and 24 weeks after the FMT.
Six patients (3 men, age range 47-73, median age 52) were treated with FMT. Four weeks following the FMT, motor, non-motor and constipation scores were improved in 5 of 6 patients. At week 24, compared to before the FMT, the changes in motor scores ranged from -13-7 points, in non-motor scores from -2 to -45 points, and in constipation scores from -12-1 point. One patient had a serious adverse event requiring admission for observation only, and no adverse events were observed in all other patients.
