RESUMO

BACKGROUND: Quick Sequential Organ Failure Assessment (qSOFA) is recommended to identify sepsis. Odontogenic infection (OI) can progress to sepsis, causing systematic inflammatory complications or organ failure. PURPOSE: The purpose of the study was to measure the association between OI location and risk for sepsis at admission. STUDY DESIGN, SETTING, AND SAMPLE: This retrospective cohort study included subjects treated for OI at Baylor University Medical Center in Dallas, TX, from January 9, 2019 to July 30, 2022. Subjects > 18 years old who were treated under general anesthesia were included. OI limited to periapical, vestibular, buccal, and/or canine spaces were excluded from the sample. PREDICTOR VARIABLE: The primary predictor variable was OI anatomic location (superficial or deep). Superficial OI infection includes submental, submandibular, sublingual, submasseteric, and/or superficial temporal spaces. Deep OI includes pterygomandibular, deep temporal, lateral pharyngeal, retropharyngeal, pretracheal, and/or prevertebral. MAIN OUTCOME VARIABLES: The primary outcome variable was risk for sepsis measured using a qSOFA score (0 to 3). A higher score (>0) indicates the patient has a high risk for sepsis. COVARIATES: Covariates were demographics, clinical, laboratory, and radiological findings, antibiotic route, postoperative endotracheal intubation, tracheostomy, intensive care unit, admission, and length of stay. ANALYSES: Descriptive and bivariate analyses were performed. A χ2 test was used for categorical variables. The Mann-Whitney U test was used for continuous variables. Statistical significance was P < .05. RESULTS: The sample was composed of 168 subjects with a mean age of 42.8 ± 21.5 and 69 (48.6%) subjects were male. There were 11 (6.5%) subjects with a qSOFA score > 0. The relative risk of a qSOFA > 0 for a deep OI is 5.4 times greater than for a superficial OI (136 (95.8) versus 21 (80.8%): RR (95% confidence interval): 5.4 (1.51 to 19.27), P = .004). After adjusting for age, sex, American Society of Anesthesiologists score, and involved anatomical spaces, there was a significant correlation between laterality and the number of involved anatomical spaces and qSOFA score (odd ratio = 9.13, 95% confidence interval: 2.48 to 33.55, adjusted P = <.001). CONCLUSION AND RELEVANCE: The study findings suggest that the OI location is associated with the qSOFA score >0.

RESUMO

This study aims to review ophthalmic injuries sustained during of robotic-assisted laparoscopic prostatectomy (RALP). A search of Medline, Embase, Cochrane and grey literature was performed using methods registered a priori. Eligible studies were published 01/01/2010-01/05/2023 in English and reported ophthalmic complications in cohorts of > 100 men undergoing RALP. The primary outcome was injury incidence. Secondary outcomes were type and permanency of ophthalmic complications, treatments, risk factors and preventative measures. Nine eligible studies were identified, representing 100,872 men. Six studies reported rates of corneal abrasion and were adequately homogenous for meta-analysis, with a weighted pooled rate of 5 injuries per 1000 procedures (95% confidence interval 3-7). Three studies each reported different outcomes of xerophthalmia, retinal vascular occlusion, and ophthalmic complications unspecified in 8, 5 and 2 men per 1000 procedures respectively. Amongst identified studies, there were no reports of permanent ophthalmic complications. Injury management was poorly reported. No significant risk factors were reported, while one study found African-American ethnicity protective against corneal abrasion (0.4 vs. 3.9 per 1000). Variables proposed (but not proven) to increase risk for corneal abrasion included steep Trendelenburg position, high pneumoperitoneum pressure, prolonged operative time and surgical inexperience. Compared with standard of care, occlusive eyelid dressings (23 vs. 0 per 1000) and foam goggles (20 vs. 1.3 per 1000) were found to reduce rates of corneal abrasion. RALP carries low rates of ophthalmic injury. Urologists should counsel the patient regarding this potential complication and pro-actively implement preventative strategies.

RESUMO

Introduction: An attractive, yet unrealized, goal in cancer therapy is repurposing psychiatric drugs that can readily penetrate the blood-brain barrier for the treatment of primary brain tumors and brain metastases. Phenothiazines (PTZs) have demonstrated anti-cancer properties through a variety of mechanisms. However, it remains unclear whether these effects are entirely separate from their activity as dopamine and serotonin receptor (DR/5-HTR) antagonists. Methods: In this study, we evaluated the anti-cancer efficacy of a novel PTZ analog, CWHM-974, that was shown to be 100-1000-fold less potent against DR/5-HTR than its analog fluphenazine (FLU). Results: CWHM-974 was more potent than FLU against a panel of cancer cell lines, thus clearly demonstrating that its anti-cancer effects were independent of DR/5-HTR signaling. Our results further suggested that calmodulin (CaM) binding may be necessary, but not sufficient, to explain the anti-cancer effects of CWHM-974. While both FLU and CWHM-974 induced apoptosis, they induced distinct effects on the cell cycle (G0/G1 and mitotic arrest respectively) suggesting that they may have differential effects on CaM-binding proteins involved in cell cycle regulation. Discussion: Altogether, our findings indicated that the anti-cancer efficacy of the CWHM-974 is separable from DR/5-HTR antagonism. Thus, reducing the toxicity associated with phenothiazines related to DR/5-HTR antagonism may improve the potential to repurpose this class of drugs to treat brain tumors and/or brain metastasis.

RESUMO

BACKGROUND AND AIMS: Endoscopic eradication therapy for Barrett's esophagus (BE)-related neoplasia is increasingly being performed at tertiary and community centers. While it has been suggested that these patients should be evaluated at expert centers, the impact of this practice has not been evaluated. We aimed to assess the impact of referral of BE-related neoplasia patients to expert centers by assessing the proportion of patients with change in pathological diagnosis and visible lesions detected. METHODS: Multiple databases were searched until December 2021 for studies of patients with BE referred from the community to expert center. The proportions of pathology grade change and newly detected visible lesions at expert centers were pooled using a random-effects model. Subgroup analyses were performed based on baseline histology and other relevant factors. RESULTS: Twelve studies were included (1630 patients). The pooled proportion of pathology grade change after expert pathologist review was 47% (95% CI 34-59%) overall and 46% (95% CI 31-62%) among patients with baseline low-grade dysplasia. When upper endoscopy was repeated at an expert center, the pooled proportion of pathology grade change was still high 47% (95% 26-69%) overall and 40% (95% CI 34-45%) among patients with baseline LGD. The pooled proportion of newly detected visible lesions was 45% (95% CI 28-63%) and among patients referred with LGD was 27% (95% CI 22-32%). CONCLUSION: An alarmingly high proportion of newly detected visible lesions and pathology grade change were found when patients were referred to expert centers supporting the need for centralized care for BE-related neoplasia patients.

RESUMO

PURPOSE: Training during oral and maxillofacial surgery residency must include exposure to the scope of the specialty, but success in practice often requires particular experience and knowledge of complex oral regenerative procedures such as bone grafting and implant surgery, as well as practice management. Osteo Science Foundation created the Clinical Observership Program (COP) in 2017 to provide residents the opportunity to spend several weeks in an established oral and maxillofacial surgery practice to increase experience in these areas. The purpose of this study is to report the results of a survey of all resident participants in the COP from 2017 to 2021 in which participants were asked to rate their experience numerically. MATERIALS AND METHODS: This is an institutional retrospective case series completed via an electronic survey sent to all participants in the COP from 2017 to 2021. The primary outcome is the subjective assessment of the COP based on six questions in which the respondent was asked to rate the program on a scale of 1 to 10 (10 being best). Categories included: 1) Did the program achieve expectations? 2) Was adequate time spent with the mentor? 3) Did you observe/participate in a variety of procedures? 4) Did the mentor provide additional didactic education? 5) Did you learn about practice management? and 6) How would you rate the overall experience? Descriptive statistics including mean score and standard deviation of each question were calculated, and no other covariates were analyzed. RESULTS: All 55 participants in the COP from 2017 to 2021 were contacted and 55 complete responses were received. The overall mean score for all categories rated by the residents was 9.63, the mean rating for questions 1 to 6 were 9.55, 9.89, 9.21, 9.60, 9.69, and 9.86 respectively, and the range of scores was 7 to 10. CONCLUSION: Overall, residents rated the COP experience highly. This survey indicates that the COP is a valuable supplemental experience in oral and maxillofacial surgery resident education.

RESUMO

Objective To describe the frequency, type, and severity of reported medication incidents that occurred at a long-term care facility (LTCF) despite electronic medication administration record and barcode-assisted medication administration (eMAR-BCMA) use. The study also contains analysis for the contribution of staff workarounds to reported medication administration errors (MAEs) using an established typology for BCMA workarounds, characterize if the eMAR-BCMA technology contributed to MAEs, and explore characteristics influencing incident severity. Design Retrospective incident report review. Setting A 239-bed LTCF in Alberta, Canada, that implemented eMAR-BCMA in 2013. Participants 270 paper-based, medication incident reports submitted voluntarily between June 2015 and October 2017. Interventions None. Results Most of the 264 resident-specific medication incidents occurred during the administration (71.9%, 190/264) or dispensing (28.4%, 75/264) phases, and 2.3% (6/264) resulted in temporary harm. Medication omission (43.7%, 83/190) and incorrect time (22.6%, 43/190) were the most common type of MAE. Workarounds occurred in 41.1% (78/190) of MAEs, most commonly documenting administration before the medication was administered (44.9%, 35/78). Of the non-workaround MAEs, 52.7% (59/112) were notassociated with the eMAR-BCMA technology, while 26.8% (30/112) involved system design shortcomings, most notably lack of a requirement to scan each medication pouch during administration. MAEs involving workarounds were less likely to reach the resident (74.4 vs 88.8%; relative risk = 0.84, 95% CI 0.72-0.97). Conclusion Administration and dispensing errors were the most reported medication incidents. eMAR-BCMA workarounds, and design shortcomings were involved in a large proportion of reported MAEs. Attention to optimal eMAR-BCMA use and design are required to facilitate medication safety in LTCFs.

RESUMO

OBJECTIVE: Hepatocellular carcinoma (HCC) is increasingly associated with non-alcoholic steatohepatitis (NASH). HCC immunotherapy offers great promise; however, recent data suggests NASH-HCC may be less sensitive to conventional immune checkpoint inhibition (ICI). We hypothesised that targeting neutrophils using a CXCR2 small molecule inhibitor may sensitise NASH-HCC to ICI therapy. DESIGN: Neutrophil infiltration was characterised in human HCC and mouse models of HCC. Late-stage intervention with anti-PD1 and/or a CXCR2 inhibitor was performed in murine models of NASH-HCC. The tumour immune microenvironment was characterised by imaging mass cytometry, RNA-seq and flow cytometry. RESULTS: Neutrophils expressing CXCR2, a receptor crucial to neutrophil recruitment in acute-injury, are highly represented in human NASH-HCC. In models of NASH-HCC lacking response to ICI, the combination of a CXCR2 antagonist with anti-PD1 suppressed tumour burden and extended survival. Combination therapy increased intratumoural XCR1+ dendritic cell activation and CD8+ T cell numbers which are associated with anti-tumoural immunity, this was confirmed by loss of therapeutic effect on genetic impairment of myeloid cell recruitment, neutralisation of the XCR1-ligand XCL1 or depletion of CD8+ T cells. Therapeutic benefit was accompanied by an unexpected increase in tumour-associated neutrophils (TANs) which switched from a protumour to anti-tumour progenitor-like neutrophil phenotype. Reprogrammed TANs were found in direct contact with CD8+ T cells in clusters that were enriched for the cytotoxic anti-tumoural protease granzyme B. Neutrophil reprogramming was not observed in the circulation indicative of the combination therapy selectively influencing TANs. CONCLUSION: CXCR2-inhibition induces reprogramming of the tumour immune microenvironment that promotes ICI in NASH-HCC.

RESUMO

Orthognathic surgery performed in conjunction with orthodontic treatment is commonly performed to correct skeletal irregularities and realign the maxillomandibular relationship to improve occlusal function and facial esthetics. A thorough understanding of soft tissue esthetics, skeletal and occlusal relationships, and surgical techniques is required to obtain successful results. Surgical techniques have evolved greatly throughout history, as technological advances such as virtual surgical planning have become available and widely used to obtain predictable movements with minimized complications. The aim of this article is to review the orthognathic surgical procedures of the mandible, with particular attention to the indications, contraindications, preoperative assessment, surgical technique, and possible complications encountered.

RESUMO

A heightened cultural emphasis on youth and beauty has resulted in an increase in cosmetic surgery in the Western world. Lip augmentation is one of the most popular cosmetic procedures done because full lips are considered youthful and voluptuous. With reliable and improved techniques, it is possible to change the appearance of the lips utilizing injectable materials and surgical techniques. This article focuses on popular materials and techniques utilized to augment the size and volume of the lips-the most common are dermal fillers. Lip augmentation requires a thorough understanding of anatomy and managing patient expectations, available materials, and techniques.

RESUMO

Metastatic disease to the oral and maxillofacial region is rare, with only about 1% of oral malignancy attributed to metastases. In approximately 20% of these patients, oral metastases are discovered before the detection of the primary tumor. Here we present a case of a 66-year-old man who presented with vague left mandibular pain and new-onset lip numbness as the first sign of occult malignancy from lung adenocarcinoma with multiple metastases.

RESUMO

OBJECTIVES: To discuss the presentation and management of infants with arhinia or congenital absence of the nose. METHODS: This case report describes an infant with arhinia that was diagnosed prenatally. In addition to a discussion of the case, a review of the literature was completed to define appropriate postnatal work-up and management. RESULTS: The patient is a term male infant, diagnosed with arhinia on ultrasound and magnetic resonance imaging (MRI) performed at 21-weeks gestational age. Upon birth, the patient was subsequently intubated, followed by tracheostomy due to complete nasal obstruction. Through a genetics evaluation, the patient was found to be heterozygous for the SMCHD1 gene, with hypomethylation at the D4Z4 locus. Plans for reconstruction will be based on future imaging and the development of any nasal patency, however, the patient's family plans to utilize a prosthetic nose until the patient is older. CONCLUSION: Arhinia is a rare condition causing respiratory distress in the neonatal period. While stabilization of the airway is the first priority, further management is not clearly defined given the rarity of the malformation. This case discusses stabilization of the airway with a review of treatment and reconstructive options.

RESUMO

BACKGROUND: Post-operative urinary incontinence is a significant concern for patients choosing to undergo a radical prostatectomy (RP) for treatment of prostate cancer. The aim of our study was to determine the effect of pre-operative MUL on 12 month continence outcomes in men having robot-assisted laparoscopic prostatectomy (RALP). METHODS: We use the South Australian Prostate Cancer Clinical Outcomes Collaborative (SA-PCCOC) database, to identify 602 patients who had undergone RALP by a high volume surgeon. Only patients who received an assessment and education by a specialist pelvic floor physiotherapist, had completed EPIC questionnaires before treatment and did not have radiotherapy treatment within 12 months of surgery were included. MUL measurements were taken from pre-operative magnetic resonance imaging (MRI) scans. The short-form version of the Expanded Prostate Cancer Index Composite (EPIC-26) was used to measure continence outcomes. Continence was defined as 100/100 in the EPIC-26 Urinary Continence domain score. RESULTS: The observed median MUL in this study was 14.6 mm. There was no association between MUL and baseline continence. MUL was associated with continence at 12 months post RALP (OR 1.13, 95% CI 1.03-1.21, p = 0.0098). In men who were continent before surgery, MUL was associated with return to continence at 12 months after RALP (OR 1.15, 1.05-1.28, p = 0.006). MUL was also associated with change in continence after surgery (ß = 1.22, p = 0.002). CONCLUSIONS: MUL had no effect on baseline continence but had a positive and significant association with continence outcomes over 12 months post RALP.

RESUMO

Cone Beam Computed Tomography (CBCT) is a valuable imaging technique in oral and maxillofacial surgery (OMS) that can help direct a surgeon's approach to a variety of conditions. A 3-dimensional analysis of head and neck anatomy allows practitioners to plan appropriately, operate with confidence, and assess results post-operatively. CBCT imaging has clear indications and limitations. CBCT offers the clinician 3-dimensional and multi-planar views for a more accurate diagnosis and treatment without the financial burden and radiation exposure of conventional computed tomography (CT) scans. Furthermore, CBCT overcomes certain limitations of 2-dimensional imaging, such as distortion, magnification, and superimposition. However, CBCT lacks the detailed depiction of soft tissue conditions for evaluation of pathologic conditions, head and neck infections, and temporomandibular joint (TMJ) disc evaluation. This review evaluates the evidence-based research supporting the application of CBCT in the various fields of oral and maxillofacial surgery, including dentoalveolar surgery, dental implants, TMJ, orthognathic surgery, trauma, and pathology, and will assess the value of CBCT in pre-operative assessment, surgical planning, and post-operative analysis when applicable. Additionally, the significant limitations of CBCT and potential areas for future research will be discussed.

RESUMO

BACKGROUND: 18-Fluoride labeled sodium fluoride (Na-18-F) positron emission tomography with computer tomography (PET/CT) has a better sensitivity and specificity than whole body bone scan (WBBS) in detecting osseous metastatic prostate cancer. We performed a pilot study of 20 men to examine what level of impact Na-18-F PET/CT has on management plans when used for staging newly diagnosed prostate cancer. MATERIALS AND METHODS: Twenty men were prospectively enrolled into the study in South Australia. Men were eligible if they had newly diagnosed, untreated, and biopsy-confirmed intermediate- or high-risk prostate cancer (D'Amico classification). WBBS and Na-18-F PET/CT scans were performed within 1 week of each other. Following review of the WBBS, treatment type and intent was documented by the treating urologist. The Na-18-F PET/CT scan was then reviewed. The impact of the Na-18-F PET/CT was measured on whether treatment modality or intent was subsequently altered: high impact = treatment intent or modality was changed; medium impact = treatment modality was modified; low impact = no change in treatment. RESULTS: In 18 men (90%), the WBBS and Na-18-F PET/CT were negative for osseous metastases. In one man (5%), the WBBS demonstrated widespread osseous metastases which were similarly demonstrated on the Na-18-F PET/CT. One man (5%) had a normal WBBS; however, the Na-18-F PET/CT demonstrated widespread osseous metastases. Subsequently, in 19 men (95%), the results of the two scans were congruent and the addition of the Na-18-F PET/CT scan demonstrated a low impact on management. In one man (5%), the addition of the Na-18-F PET/CT had a high impact as treatment type and intent was altered. CONCLUSIONS: Our pilot study is the first of its kind in Australia, and our findings suggest that Na-18-F PET/CT is a safe and feasible modality for staging prostate cancer. However, its true impact on prostate cancer management warrants further investigation.

RESUMO

PURPOSE: Allogeneic cartilage grafting has multiple uses in rhinoplasty. Autogenous cartilage is frequently used in cases of nasal obstruction or reconstruction, but harvesting grafts can cause complications or might be contraindicated. Rhinoplasties on the patient with a cleft might require costochondral grafts. Allogeneic rib is an effective and safe alternative to autogenous grafts, prevents complications, and obviates postoperative admission after rib harvest. MATERIALS AND METHODS: Patients who had allogeneic cartilage placed during functional or reconstructive rhinoplasty were studied from 2 institutions, including 19 who had functional rhinoplasty using allogeneic Cartiform patellar cartilage grafts and 15 patients who underwent reconstructive cleft rhinoplasty with allogeneic rib cartilage. Postoperative follow-up was at least 6 months, and graft handling characteristics and improvement in breathing were assessed. Internal and external nasal valve (INV and ENV, respectively) patencies were evaluated in patients who received the Cartiform grafts, and cosmetic outcomes were rated for patients with reconstructed clefts. RESULTS: The average age of patients who underwent functional rhinoplasty was 57.3 years, and all were men with compromised nasal breathing. Cartiform cartilage was used to repair INV or ENV collapse. Postoperatively, all patients had patent INVs and ENVs and reported improved nasal breathing. Patients who received the rib allograft had an average age of 18 years and 40% were male; all had severe nasal deformities secondary to cleft or craniofacial conditions. Patients rated their preoperative nasal breathing as 4 of 10 on average and cosmetic appearance as 3 of 10; postoperatively, these were rated as 9 of 10. Complications were not noted, except for 1 superficial infection (unrelated to the graft) and 1 hypertrophic scar. There were no postoperative admissions. The mechanical and handling properties of the Cartiform and allogeneic rib were appropriate. CONCLUSION: Allogeneic cartilage is an acceptable alternative to autologous cartilage in functional and reconstructive rhinoplasty.

RESUMO

Several recent studies have illustrated the beneficial effects of living in an enriched environment on improving human disease. In mice, environmental enrichment (EE) reduces tumorigenesis by activating the mouse immune system, or affects tumor bearing animal survival by stimulating the wound repair response, including improved microbiome diversity, in the tumor microenvironment. Provided here is a detailed procedure to assess the effects of environmental enrichment on the biodiversity of the microbiome in a mouse colon tumor model. Precautions regarding animal breeding and considerations for animal genotype and mouse colony integration are described, all of which ultimately affect microbial biodiversity. Heeding these precautions may allow more uniform microbiome transmission, and consequently will alleviate non-treatment dependent effects that can confound study findings. Further, in this procedure, microbiota changes are characterized using 16S rDNA sequencing of DNA isolated from stool collected from the distal colon following long-term environmental enrichment. Gut microbiota imbalance is associated with the pathogenesis of inflammatory bowel disease and colon cancer, but also of obesity and diabetes among others. Importantly, this protocol for EE and microbiome analysis can be utilized to study the role of microbiome pathogenesis across a variety of diseases where robust mouse models exist that can recapitulate human disease.

RESUMO

Urolithiasis is a significant worldwide source of morbidity, constituting a common urological disease that affects between 10 and 15% of the world population. Recent technological and surgical advances have replaced the need for open surgery with less invasive procedures. The factors which determine the indications for percutaneous nephrolithotomy include stone factors (stone size, stone composition, and stone location), patient factors (habitus and renal anomalies), and failure of other treatment modalities (ESWL and flexible ureteroscopy). The accepted indications for PCNL are stones larger than 20 mm2, staghorn and partial staghorn calculi, and stones in patients with chronic kidney disease. The contraindications for PCNL include pregnancy, bleeding disorders, and uncontrolled urinary tract infections. Flexible ureteroscopy can be one of the options for lower pole stones between 1.5 and 2 cm in size. This option should be exercised in cases of difficult lower polar anatomy and ESWL-resistant stones. Flexible ureteroscopy can also be an option for stones located in the diverticular neck or a diverticulum. ESWL is the treatment to be discussed as a option in all patient with renal stones (excluding lower polar stones) between size 10 and 20 mm. In addition, in lower polar stones of size between 10 and 20 mm if the anatomy is favourable, ESWL is the option. In proximal ureteral stones, ESWL should be considered as a option with flexible ureteroscopy Active monitoring has a limited role and can be employed in post-intervention (PCNL or ESWL) residual stones, in addition, asymptomatic patients with no evidence of infection and fragments less than 4 mm can be monitored actively.

RESUMO

OBJECTIVE: Facial resurfacing with a CO2 laser has been used for treatment of pathologic lesions and for cosmetic purposes. Postoperative complications and problems after laser resurfacing include infections, acneiform lesions, and pigment changes. This retrospective study describes the most common problems and complications in 105 patients and assesses postoperative pain in 38 patients. STUDY DESIGN: All patients received CO2 laser resurfacing for treatment of malignant/premalignant lesions and had postoperative follow-up to assess problems and complications. Some had follow-up to assess postoperative pain. All patients had Fitzpatrick I-III skin types and underwent the same perioperative care regimen. RESULTS: There were 11 problems and 2 complications. Problems included infection, acneiform lesion/milia, and uncontrolled postoperative pain. Complications included hyperpigmentation. Among the postoperative pain group, 53% reported no pain and the rest had mild or moderate pain. CONCLUSION: Complications are rare. Infection and acneiform lesions/milia were the most common problems, as previously reported. Most patients do not experience postoperative pain.

RESUMO

We highlight two cases of transperitoneal robot-assisted radical prostatectomy (RARP) in patients with pelvic kidneys because of congenital development and renal transplant. These uncommon cases present a challenge to the surgeon contemplating surgery because of access and anomalous vascular and ureteral anatomy. We describe the technical considerations that are paramount in effectively completing transperitoneal RARP, and believe it should be considered as a treatment option in men with pelvic kidneys.
