RESUMEN

BACKGROUND: Serial neurological examinations (NEs) are routinely recommended in the intensive care unit (ICU) within the first 24 hours following a traumatic brain injury (TBI). There are currently no widely accepted guidelines for the frequency of NEs. Disruptions to the sleep-wake cycles increase the delirium rate. We aimed to evaluate whether there is a correlation between prolonged hourly (Q1)-NE and development of delirium and to determine if this practice reduces the likelihood of missing the detection of a process requiring emergent intervention. METHODS: A retrospective analysis of patients with mild/moderate TBI, admitted to the ICU with serial NEs, was performed. Cohorts were stratified by the duration of exposure to Q1-NE, into prolonged (≥24 hours) and nonprolonged (<24 hours). Our primary outcomes of interest were delirium, evaluated using the Confusion Assessment Method; radiological progression from baseline images; neurological deterioration (focal neurological deficit, abnormal pupillary examination, or Glasgow Coma Scale score decrease >2); and neurosurgical procedures. RESULTS: A total of 522 patients were included. No significant differences were found in demographics. Patients in the prolonged Q1-NE group (26.1%) had higher Injury Severity Score with similar head Abbreviated Injury Score, significantly higher delirium rate (59% vs. 35%, p < 0.001), and a longer hospital/ICU length of stay when compared with the nonprolonged Q1-NE group. No neurosurgical interventions were found to be performed emergently as a result of findings on NEs. Multivariate analysis demonstrated that prolonged Q1-NE was the only independent risk factor associated with a 2.5-fold increase in delirium rate. The number needed to harm for prolonged Q1-NE was 4. CONCLUSION: Geriatric patients with mild/moderate TBI exposed to Q1-NE for periods longer than 24 hours had nearly a threefold increase in ICU delirium rate. One of five patients exposed to prolonged Q1-NE is harmed by the development of delirium. No patients were found to directly benefit as a result of more frequent NEs. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.

RESUMEN

BACKGROUNDSepsis remains a major clinical challenge for which successful treatment requires greater precision in identifying patients at increased risk of adverse outcomes requiring different therapeutic approaches. Predicting clinical outcomes and immunological endotyping of septic patients generally relies on using blood protein or mRNA biomarkers, or static cell phenotyping. Here, we sought to determine whether functional immune responsiveness would yield improved precision.METHODSAn ex vivo whole-blood enzyme-linked immunosorbent spot (ELISpot) assay for cellular production of interferon γ (IFN-γ) was evaluated in 107 septic and 68 nonseptic patients from 5 academic health centers using blood samples collected on days 1, 4, and 7 following ICU admission.RESULTSCompared with 46 healthy participants, unstimulated and stimulated whole-blood IFN-γ expression was either increased or unchanged, respectively, in septic and nonseptic ICU patients. However, in septic patients who did not survive 180 days, stimulated whole-blood IFN-γ expression was significantly reduced on ICU days 1, 4, and 7 (all P < 0.05), due to both significant reductions in total number of IFN-γ-producing cells and amount of IFN-γ produced per cell (all P < 0.05). Importantly, IFN-γ total expression on days 1 and 4 after admission could discriminate 180-day mortality better than absolute lymphocyte count (ALC), IL-6, and procalcitonin. Septic patients with low IFN-γ expression were older and had lower ALCs and higher soluble PD-L1 and IL-10 concentrations, consistent with an immunosuppressed endotype.CONCLUSIONSA whole-blood IFN-γ ELISpot assay can both identify septic patients at increased risk of late mortality and identify immunosuppressed septic patients.TRIAL REGISTRYN/A.FUNDINGThis prospective, observational, multicenter clinical study was directly supported by National Institute of General Medical Sciences grant R01 GM-139046, including a supplement (R01 GM-139046-03S1) from 2022 to 2024.

CONCLUSIONS: A whole blood IFNγ ELISpot assay can both identify septic patients at increased risk of late mortality, and identify immune-suppressed, sepsis patients.

RESUMEN

Importance: Facial paralysis (FP) after surgery has substantial functional, emotional, and financial consequences. Most iatrogenic FP is managed by watchful waiting, with the expectation of facial function recovery. A potential treatment is physical therapy (PT). Objective: To investigate whether noninvasive PT compared with no PT or other intervention improves facial nerve outcomes in adults with iatrogenic FP. Evidence Review: Patients with noniatrogenic FP, facial reanimation surgery, and invasive adjunctive treatments (acupuncture or botulinum toxin injection) were excluded. A systematic review was conducted for records discussing iatrogenic FP and PT; a search for these records was performed using Ovid MEDLINE (1946-2019), Embase (1947-2019), Scopus (1823-2019), Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, World Health Organization International Clinical Trials Registry Platform (2004-2019), and ClinicalTrials.gov (1997-2019). The references of all the included articles were also assessed for eligible studies. All human participant, English-language study designs with at least 2 cases were included. Quality assessment was performed using the Methodological Index for Non-randomized Studies (MINORS) and the revised Cochrane Risk of Bias 2 (RoB 2) tool for randomized controlled trials. All search strategies were completed on May 16, 2019, and again on October 1, 2019. Findings: Fifteen studies (7 of which were retrospective cohort studies) and 313 patients with iatrogenic FP were included in the systematic review. Most iatrogenic FP (166 patients [53%]) was associated with parotidectomy; traditional PT (ie, facial massage) was the most common intervention (196 patients [63%]). The use of various facial grading systems and inconsistent reporting of outcomes prevented direct comparison of PT types. Conclusions and Relevance: Because of heterogeneity in reported outcomes of facial nerve recovery, definitive conclusions were unable to be made regarding the association between PT and outcomes of iatrogenic FP. Physical therapy probably has benefit and is associated with no harm in patients with iatrogenic FP.

RESUMEN

Nasal deformity associated with typical cleft lip can cause aesthetic and functional issues that are difficult to address. The degree of secondary nasal deformity is based on the extent of the original cleft deformity, growth over time, and any prior surgical correction to the nose or lip. Repair and reconstruction of these deformities require comprehensive understanding of embryologic growth, the cleft anatomy, as well as meticulous surgical technique and using a spectrum of structural grafting. This article reviews cleft lip nasal deformity, presurgical care, primary cleft rhinoplasty, and definitive cleft septorhinoplasty with a focus on aesthetics and function.

RESUMEN

PURPOSE OF REVIEW: Abnormal scarring remains a poorly understood but functional and aesthetic consequence of surgical and traumatic wounds. The purpose of this review is to describe the current state of the science behind the prevention and management of these scars. RECENT FINDINGS: A recent update in the International Clinical Recommendations on Scar Management provides a wealth of information on new and revised treatments for hypertrophic scars and keloids. Silicone-based products continue to be the premier option for prevention and initial treatment of hypertrophic and keloid scars. There is growing evidence demonstrating the efficacy of intralesional corticosteroids and 5-fluorouracil. Laser therapy remains a second-line treatment option, with low-level evidence supporting the use of pulse dye lasers and ablative fractional lasers. SUMMARY: Although there remains no 'gold standard' for the prevention and treatment of hypertrophic scars and keloids, silicone gel products and microporous paper tape present the best conservative options. A stepwise algorithm for the treatment of hypertrophic scars or keloids based on the characteristics and responsiveness of the scar presents the best management strategy. Combination therapy (including steroid injections, 5-fluorouracil, and pulse dye laser) proves to be the strongest option for the nonsurgical management of severe hypertrophic scars and keloids.
