Recent studies of panniculectomy outcomes have reported variable complication rates ranging from 8.65% to 56%. Meanwhile, reported abdominoplasty complication rates are considerably lower (~4%). This discrepancy may be attributable to inaccurate inclusion of abdominoplasty patients in panniculectomy cohorts. We performed the current study to better characterize panniculectomy complication rates at a large tertiary care center.

We performed a retrospective review of patients who underwent abdominoplasty or panniculectomy at the Johns Hopkins Hospitals between 2010 and 2017. Patients were identified by Common Procedural Terminology codes (15847/17999, 15830) confirmed via the operative note. We examined postoperative complication rates including surgical site infection, seroma formation, wound dehiscence, readmission/reoperation, and postoperative length of stay (LOS). We used parametric and nonparametric methods to determine differences between abdominoplasty and panniculectomy outcomes, as well as logistincluding improved hygiene and enhanced mobility. However, this study demonstrates that panniculectomy patients may have significantly higher complication rates initially and 30 days postoperatively and longer LOS than individuals undergoing abdominoplasty.

Biological glue is already used as a hemostatic agent and tissue adhesive in plastic surgery. This study evaluates the use of this glue as an alternative to suction drainage for the adhesion of tissue-expanded flaps in pediatric patients.

This is a retrospective, multicenter case-control study on 48 flap procedures conducted on 42 children (5 months-12 years of age) between 2004 and 2017, comparing a "glue" group (n = 24) with a control group (n = 24), in which a classic redon drain was used. The control patients were matched according to age, etiology, location of the lesion, and the size of the expander. The primary end point was the duration of hospital stay.

The conditions were 24 cases of congenital nevus, 14 of cicatricial alopecia, and 10 of sebaceous hamartoma. Twenty-nine lesions were located on the scalp, 15 on the back, 2 on the thigh, and 2 on the buttocks.The average surgical durations (48 ± 24 vs 63 ± 32 minutes, P = 0.13) and average room occupancy time (126 ± 21 vs 139 ± 44 minutes, P = 0.29) were similar between the glue group and the control group. However, the average duration of hospital stay was lower in the glue group (1.5 ± 1.5 days) than in the control group (3.6 ± 1.3 days, P < 0.0001). The complication rates between the groups were similar.

The application of glue on expanded flaps is as reliable as suction drainage with the advantage of reducing the duration of hospital stay and potentially enabling outpatient treatment for certain patients.

In fingertip replantation with arterial anastomosis alone, many external bleeding techniques have been described to satisfy venous outflow, and some patients require blood transfusions. We used a pulp tissue reduction method to avoid the need for external bleeding techniques and blood transfusions.

We examined 18 fingers in cases of Ishikawa's subzone II, III, and IV amputation that were replanted with artery-only anastomosis and pulp tissue reduction from April 2003 to March 2018. The method consisted of pulp tissue reduction to the level of the fingerprint core, bone fixation without gaps to promote venous drainage through bone marrow, and pinprick testing twice a day. Prostaglandin E1 and/or urokinase were administered intravenously, but no other anticoagulants were used systemically or locally. Postoperatively, only the pinprick test was performed twice a day for 5 days.

The patients ranged in age from 26 to 74 years (mean, 47 years). There were 13 men and 5 women. The total success rate was 89% (16mosis, a pulp tissue reduction method, is effective for replant survival when subcutaneous venous repair is impossible because a reduced pulp volume may facilitate replant survival under conditions of irregular venous drainage, such as bone marrow drainage.

Voltage-gated sodium channel Nav1.7 has been validated as a perspective target for selective inhibitors with analgesic and anti-itch activity. The objective of this study was to discover new candidate compounds with Nav1.7 inhibitor properties. The authors hypothesized that their approach would yield at least one new compound that inhibits sodium currents in vitro and exerts analgesic and anti-itch effects in mice.

In silico structure-based similarity search of 1.5 million compounds followed by docking to the Nav1.7 voltage sensor of Domain 4 and molecular dynamics simulation was performed. Patch clamp experiments in Nav1.7-expressing human embryonic kidney 293 cells and in mouse and human dorsal root ganglion neurons were conducted to test sodium current inhibition. Formalin-induced inflammatory pain model, paclitaxel-induced neuropathic pain model, histamine-induced itch model, and mouse lymphoma model of chronic itch were used to confirm in vivo activity of the selected compound.

After in silico screed mechanical allodynia, and inhibited histamine-induced acute itch and lymphoma-induced chronic itch.

This study's computer-aided drug discovery approach yielded a new Nav1.7 inhibitor that shows analgesic and anti-pruritic activity in mouse models.

To improve understanding of the respiratory behavior of oliceridine, a μ-opioid receptor agonist that selectively engages the G-protein-coupled signaling pathway with reduced activation of the β-arrestin pathway, the authors compared its utility function with that of morphine. Selleck BAL-0028 It was hypothesized that at equianalgesia, oliceridine will produce less respiratory depression than morphine and that this is reflected in a superior utility.

Data from a previous trial that compared the respiratory and analgesic effects of oliceridine and morphine in healthy male volunteers (n = 30) were reanalyzed. A population pharmacokinetic-pharmacodynamic analysis was performed and served as basis for construction of utility functions, which are objective functions of probability of analgesia, P(analgesia), and probability of respiratory depression, P(respiratory depression). The utility function = P(analgesia ≥ 0.5) - P(respiratory depression ≥ 0.25), where analgesia ≥ 0.5 is the increase in hand withdrawal latency in the cold pressor test by at least 50%, and respiratory depression ≥ 0.
