Overprescribing of opioid medications for patients to be used at home after surgery is common. We sought to ascertain important patient and procedural characteristics that are associated with low versus high rates of self-reported utilization of opioids at home, 1-4 weeks after discharge following gastrointestinal surgery.

Defective skin's acidic mantle is a component of atopic dermatitis (AD) pathophysiology. We mapped the skin pH and determine its relationship with transepidermal water loss (TEWL), hydration and disease severity.

The purpose of this study was to compare the trial success rate between anatomic lead placement (AP) and paresthesia-mapped (PM) lead placement techniques for spinal cord stimulation (SCS) using a nonlinear burst stimulation pattern.

Atopic dermatitis (AD) is characterized by exacerbations and remissions of eczematous skin, underlain by impaired skin barrier and aberrant Th2-type and Th-22 cytokine production. A number of allergens, in particular contact with fur animals, may aggravate the disease. This study seeks to define the influence of having a regular contact with a pet cat at home on the severity of symptoms and signs of AD. We addressed the issue using the SCORing Atopic Dermatitis (SCORAD) and visual analog (VAS) scores to assess the intensity of pruritus and by measuring the blood content of specific IgE and IL-4, IL-13, and IL-22 cytokines. The study group consisted of 47 adult patients suffering from AD since childhood, 18 of whom declared having regular contact with a cat and the remaining 29 who denied it. There also was a control group consisted of 16 healthy volunteers with no AD signs. The SCORAD and VAS scores were significantly higher in patients in contact with a cat than in those without it (median SCORAD 61.0 vs. 50.4 and VAS 9.0 vs. 4.0 points, respectively). The sIgE of a majority of patients (94.4%) in contact with a cat was in Class V-VI, compared with just a few patients (3.4%) with no such contact, having sIgE in the same classes (p < 0.001). Significant correlations were revealed between SCORAD and VAS scores and the class level of serum sIgE value. In addition, IL-22 was a single elevated cytokine, only in the patients in contact with a cat, and it correlated with pruritus severity. The results of the study underline the need to beware of the cat fur allergen, and they stress forethought and caution in acquiring and keeping a pet cat by patients suffering from AD.

Schefflera rubriflora, a plant native to Yunnan Province in China, is often used to treat ailments such as neuropathic pain, tracheitis, and cough. However, the active components imparting these pharmacological effects are largely unexplored. In this study, five novel lignans and three new derivatives of benzoid or pyran were isolated from the leaves and twigs of S. rubriflora. The structures of these compounds were determined by the comprehensive analyses of the 1D and 2D NMR spectra and ESI mass spectra and a comparison of the obtained data with those of the literature data. All the compounds were tested for the inhibition of IL-6 expression. Three of the isolated compounds could inhibit the expression by 52% to 72%.

Amyloidoma is a highly unusual presentation of amyloidosis in tumoral or nodular form. Isolated soft tissue amyloidomas in individuals with end-stage renal disease on chronic hemodialysis is exceedingly rare, particularly in the era of advanced dialysis technologies. We report the case of a 55-year-old male with end-stage renal disease due to autosomal-dominant polycystic kidney disease, on HD for over 30 years, who was found to have soft-tissue, dialysis-related (β -microglobulin) amyloidomas (DRA). He presented with painful, palpable masses within the thoracic and abdominal walls. Serum β -microglobulin level was only mildly elevated at 24.9 mg/L. Biopsy confirmed amyloidosis with positivity for Congo Red staining and apple-green birefringence under polarized light. Amyloid subtyping with immunohistochemistry showed positive β -microglobulin staining within the deposits. Conservative therapy involving pain management and close monitoring resulted in eventual improvement in symptoms and thus proved to be a viable option for treatment.

To evaluate the anatomy of the serratus plane in dogs to establish the optimal landmarks for a superficial serratus plane (SSP) block and evaluate ropivacaine-methylene blue solution dispersion with three volumes of injection.

C2 vertebral body (axis) lesions are often approached anteriorly combined with posterior stabilization of craniovertebral junction (CVJ). The anterior approach has its limitations. A posterolateral corridor is an alternative access to the C2 body lesions, and this alone may suffice in selected cases. We describe our experience with C2 body lesions, dealt primarily through posterior approach, and propose an algorithm in the management of such cases.
