RESUMO

BACKGROUND: Patients with sickle cell disease (SCD) frequently undergo prophylactic red blood cell (RBC) exchange transfusion and simple transfusion (RCE/T) to prevent complications of disease, such as stroke. These treatment procedures are performed with a target hemoglobin S (HbS) of ≤30%, or a goal of maintaining an HbS level of <30% immediately prior to the next transfusion. However, there is a lack of evidence-based instructions for how to perform RCE/T in a way that will result in an HbS value <30% between treatments. PRINCIPAL OBJECTIVE: To determine whether targets for post-treatment HbS (post-HbS) or post-treatment HCT (post-HCT) can help to maintain an HbS <30% or <40% between treatments. MATERIALS AND METHODS: We performed a retrospective study of patients with SCD treated with RCE/T at Montefiore Medical Center from June 2014 to June 2016. The analysis included patients of all ages, and data including 3 documented parameters for each RCE/T event: post-HbS, post-HCT, and follow-up HbS (F/u-HbS), which is the pre-treatment HbS prior to the next RCE/T. Generalized linear mixed model was used for estimating the association between post-HbS or post-HCT levels and F/u-HbS <30%. RESULTS: Based on our results, targeting post-HbS ≤10% was associated with higher odds of having events of F/u-HbS <30% between monthly treatments. Targeting post-HbS ≤15% was associated with higher odds of events of F/u-HbS < 40%. As compared to post-HCT ≤30%, a post-HCT >30%-36% did not contribute to more F/u-HbS <30% or HbS <40% events. CONCLUSIONS: For patients with SCD undergoing regular RCE/T for stroke prevention, a post-HbS ≤10% can be used as a goal to help maintain an HbS <30% for 1 month, and a post-HbS ≤15% allowed patients to maintain HbS <40%.

RESUMO

Patients with sickle cell disease (SCD) suffer from intravascular hemolysis associated with vascular injury and dysfunction in mouse models, and painful vaso-occlusive crisis (VOC) involving increased attachment of sickle erythrocytes and activated leukocytes to damaged vascular endothelium. Patrolling monocytes, which normally scavenge damaged cells and debris from the vasculature, express higher levels of anti-inflammatory heme oxygenase 1 (HO-1), a heme degrading enzyme. Here, we show that HO-1-expressing patrolling monocytes protect SCD vasculature from ongoing hemolytic insult and vaso-occlusion. We found that a mean 37% of patrolling monocytes from SCD patients express very high levels of HO-1 (HO-1hi) vs 6% in healthy controls and demonstrated that HO-1hi expression was dependent on uptake of heme-exposed endothelium. SCD patients with a recent VOC episode had lower numbers of HO-1hi patrolling monocytes. Heme-mediated vaso-occlusion by mouse SCD red blood cells was exacerbated in mice lacking patrolling monocytes, and reversed following transfer of patrolling monocytes. Altogether, these data indicate that SCD patrolling monocytes remove hemolysis-damaged endothelial cells, resulting in HO-1 upregulation and dampening of VOC, and that perturbation in patrolling monocyte numbers resulting in lower numbers of HO-1hi patrolling monocyte may predispose SCD patients to VOC. These data suggest that HO-1hi patrolling monocytes are key players in VOC pathophysiology and have potential as therapeutic targets for VOC.

RESUMO

OBJECTIVES: To identify the common bacteria in recent peritonsillar abscesses and the prevalence of antibiotic resistance and compare both between adults and children. METHODS: This is a retrospective chart review at a single academic institution of patients who underwent either incision and drainage or tonsillectomy for a peritonsillar abscess between 2002 and 2012 (n=69). Medical records were reviewed for cultures, comorbidities, and drainage procedures. RESULTS: Cultures obtained from 62.32% of peritonsillar abscesses were polymicrobial, and 34.78% were monomicrobial. The most common pathogens were ß-hemolytic Streptococcus (31.88%), α-hemolytic Streptococcus (21.74%), Neisseria (14.49%), and Streptococcus milleri (13.04%). Group A ß-hemolytic streptococcus was more common in children and Streptococcus milleri was more common in adults. Alpha-hemolytic streptococcus was resistant to clindamycin (6.67%) and erythromycin (6.67%). Streptococcus milleri was resistant to clindamycin (11.11%) and erythromycin (11.11%). Staphylococcus was resistant to penicillin (37.5%), oxacillin (25%), erythromycin (25%), and clindamycin (12.5%). CONCLUSIONS: ß- and α-hemolytic Streptococci, Neisseria, and Streptococcus milleri are the most common pathogens. Streptococcus milleri is more common in adults, and ß-hemolytic streptococcus is more common in children. Resistance to clindamycin and erythromycin is common in Streptococci and Staphylococci, and penicillin resistance is common in Staphylococci.

RESUMO

Objective: To determine if performing popliteal nerve blocks preoperatively in patients undergoing fibula-free flap surgery for head and neck cancer reconstruction decreases subjective pain scores decreases narcotic usage, and improves mobility in the acute postoperative time period when compared to alternative pain control regimens. Methods: A retrospective review of the medical records of patients who underwent fibula-free flap reconstruction for head and neck malignancy at SUNY Upstate Medical University during the time period from 2015 to 2022 was performed. Collected data consisted of patient demographics and clinical characteristics, postoperative pain management modalities, reported pain scores, postoperative narcotic usage, length of hospital stay, and days until out of bed without personal assistance. Results: A total of 40 patients were included in the study. The average reported pain score was reduced in the nerve block group compared to the control group (1.7 vs. 4.0, p-value = .003). Similarly, the average maximum reported pain score was also lower in patients who received a nerve block (3.4 vs. 6.9, p-value = .002). None of the patients who received popliteal nerve blocks required pain control with parenteral narcotics postoperatively, whereas 82.9% of patients without a nerve block did. Patients who received a popliteal nerve block consumed an average of 103.5 MME, whereas those who did not receive a block consumed an average of 523.0 MME. No statistically significant difference was found between the groups regarding time from surgery until transfer without personal assistance or length of hospital stay. Conclusion: Popliteal nerve blocks can reduce postoperative pain in patients undergoing fibula-free flap reconstruction for head and neck cancer.

RESUMO

OBJECTIVE: Patient and equipment safety has become increasingly scrutinized in today's medical care. Routine otolaryngologic evaluation often involves suctioning with Frazier-type suction devices in the ear canal for improved visualization, but data are limited on the potential acoustic trauma from ear canal suction devices. This study intends to document the objective and subjective effects of ear canal suctioning to identify any risk for hearing threshold shifts or other potential negative effects. PATIENTS AND METHODS: Prospective study on 21 healthy volunteers enlisted for evaluation. Presuctioning tympanogram, audiogram, and otoacoustic emissions data were obtained. Spectrum analyses were recorded during ear canal suctioning with a probe microphone placed lateral to the tympanic membrane. Subjective data were recorded, and a follow-up audiogram and otoacoustic emissions were obtained to identify any temporary threshold shifts. RESULTS: Spectrum analyses revealed a high degree of variability between subjects. A peak intensity of 111 dB sound pressure level was recorded. All patients tolerated suctioning, and none reported hearing loss. No threshold shifts were observed. Subjective data failed to correlate with the objective recorded intensities. CONCLUSIONS: Clinicians and patients need to be acutely aware of potential risks and benefits from any medical intervention. Routine ear canal suctioning can be extremely loud and uncomfortable for patients. This study failed to document objective proof of hearing detriment from ear canal suctioning, although the possibility exists during office and surgical intervention. Further study and potential alternative suctioning methods deserve attention.

RESUMO

INTRODUCTION: Gastropericardial fistula, a connection between the upper gastrointestinal tract and pericardium, is a rare clinical finding most commonly associated with postsurgical complications, as well as direct tissue invasion from gastric cancer. Case Report. We report a case of a 58-year-old Caucasian woman with metastatic colon cancer treated with FOLFOX, a combination chemotherapy regimen, and bevacizumab who presented with chest pain. She was ruled out for acute coronary syndrome, aortic dissection, or pulmonary embolism. A computed tomography (CT) scan of her chest showed pneumopericardium. A barium swallow ruled out esophageal ulceration, and esophagogastroduodenoscopy (EGD) showed a large penetrating gastric ulcer with no evidence of gastric dysplasia or malignancy or evidence of Helicobacter pylori (H. pylori). The patient underwent median sternotomy with gastric ulcer resection and repair, as well as pericardial washout and pericardial chest tube placement. After an uncomplicated course, she was safely discharged home. CONCLUSION: Given that gastrointestinal ulceration and perforation are known phenomena in patients taking vascular endothelial growth factor (VEGF) inhibitors, surveillance endoscopy may be beneficial to discover them before they result in potentially fatal complications such as gastropericardial fistulas.

RESUMO

Introduction. Marfan syndrome (MFS) is a rare connective tissue disorder attributed to a defect in the fibrillin-1 gene. Aortic aneurysms and dissection are common causes of morbidity and mortality in Marfan syndrome. Case Report. A 43-year-old female with a history of MFS and a 4.0 cm dilated ascending aorta presented to her cardiologist reporting that since a C-section two years prior, the left side of her abdomen painlessly protruded when standing. An outpatient CT scan of the abdomen/pelvis noted a 5.5 cm abdominal aortic dissection, and she was directed to the hospital. Repeat CT scan of the abdomen/pelvis revealed a 5.6 cm dissecting aneurysm of the infrarenal abdominal aorta. The patient was admitted to the ICU and started on a nitroglycerin drip to maintain systolic blood pressure less than 110 mmHg. The patient underwent repair of her abdominal aortic dissection via a retroperitoneal approach, and she tolerated the procedure well. She was started on metoprolol tartrate 12.5 mg BID and aspirin 81 mg postoperatively. She was safely discharged with follow-up care. Conclusion. This case stresses the importance of having a low threshold to obtain imaging in a MFS patient with protruding abdomen, even though the patient may not have pain and be hemodynamically stable.

RESUMO

Abscesses in the head and neck frequently have odontogenic sources. As bacterial pathogens and antibiotic resistance patterns may change over time and based on location, we describe the current common bacteria found in odontogenic abscesses, the prevalence of antibiotic resistance, and differences in each between pediatric and adult patients in Upstate New York. This is a retrospective review of patients who underwent drainage of odontogenic abscesses (n = 131) from 2002 to 2012 at an academic institution. The medical records were reviewed for results of abscess cultures, comorbidities, and drainage procedures. Polymicrobial sources were identified in 60.3% and monomicrobial in 33.6%. Overall, the most common bacteria were alpha hemolytic Streptococci (33.6%), Streptococcus milleri (32.1%), Prevotella (16.8%), and coagulase-negative Staphylococcus (14.5%). Candida and Morganella spp were more common in children than in adults. Overall, antibiotic resistance was observed in seven different pathogens. The most common antibiotic resistances were to clindamycin and erythromycin, which should be considered when deciding initial antibiotic therapy, especially in adult patients, who trended in this study toward having pathogens with higher rates of resistance.

RESUMO

BACKGROUND: Left ventricular assist device (LVAD) recipients undergoing heart transplantation have increased bleeding risk. We compared conventional warfarin reversal with fresh frozen plasma vs 4-factor prothrombin complex concentrate (PCC) and the effect on transfusion requirements, blood bank costs, and clinical outcomes. METHODS: A retrospective review identified 60 consecutive LVAD recipients undergoing heart transplantation divided into two groups: 30 (no PCC) received fresh frozen plasma and 30 (PCC) received PCC. Patient characteristics, intraoperative and postoperative transfusion requirements, short-term clinical outcomes, and blood bank costs were compared. PCC association with transfusion requirements was assessed by multivariate linear regression. RESULTS: Patients who received PCC were younger (50 ± 11 vs 57 ± 13 years, p = 0.02), fewer had ischemic cardiomyopathy (23% vs 60%, p = 0.01), had more than one prior sternotomy (7% vs 30%, p = 0.04), and had higher preoperative hemoglobin (11.8 ± 1.8 vs 10.4 ± 1.8 g/dL, p = 0.01). The PCC group had a significantly shorter bypass time (185 vs 217 minutes, p = 0.01), received less fresh frozen plasma (2 vs 5 units, p = 0.03), cryoprecipitate (0 vs 2 units, p = 0.05), and total blood products (9 vs 13.5 units, p = 0.03) intraoperatively, and was less likely to require delayed sternal closure (3% vs 23%, p = 0.05). On multivariate linear regression, PCC was significantly associated with decreased intraoperative transfusion (ß = -6.09, p = 0.02). There was no difference in thromboembolic events or in-hospital death. Total blood bank costs were $4,949 for PCC and $3,677 for no PCC (p = 0.01). CONCLUSIONS: Although more costly, PCC reduced transfusion requirements and delayed sternal closure in heart transplant recipients bridged with LVAD, justifying its use over traditional warfarin reversal.

RESUMO

IMPORTANCE: This study examines the association between isolated mandible fractures and mild traumatic brain injury (mTBI). OBJECTIVE: To determine the rates of mTBI in patients who have sustained isolated mandible fractures. DESIGN, SETTING, AND PARTICIPANTS: A prospective study was conducted among patients who sustained isolated mandible fractures within 24 hours of presentation. Patients were administered the Military Acute Concussion Evaluation (MACE). Recorded data included demographics, time since injury, use of alcohol or illicit drugs, nonfacial pain, and mechanism of injury. All patients were evaluated in the emergency department of a level I trauma center between June 20, 2013, and June 20, 2014. In addition, discharge data from the Nationwide Inpatient Sample database was analyzed to identify current rates of patients with a diagnosis of both mandible fractures and concussions. MAIN OUTCOMES AND MEASURES: Rates of concussion. Patients with a MACE score of less than 25 were considered to have mTBI. RESULTS: Sixteen patients met the study criteria over a 1-year period. Fourteen patients (88%) were male, and mean age was 27.5 years. The mean time since injury was 11.25 hours (range, 3-21 hours). The mechanism of injury was assault in 12 patients (75%), sports in 2 patients (13%), all-terrain vehicle crash in 1 patient (6%), and biking in 1 patient (6%). Eight patients (50%) admitted to the use of alcohol, and none reported the use of illicit drugs. Eleven patients (69%) reported loss of consciousness. Twelve patients (75%) met criteria for concussion according to the MACE. Among these 12 patients, 7 (58%) admitted to the use of alcohol at the time of injury. There was no relationship between the rates of concussion and the use of alcohol. CONCLUSIONS AND RELEVANCE: Mandible fractures are often sustained after high-force impacts during altercations between men. In our study, a 75% (12 of 16) rate of concussions associated with isolated mandible fractures was identified. Patients with isolated mandible fractures may benefit from being screened for concussion and referred to a concussion clinic. LEVEL OF EVIDENCE: 4.

RESUMO

Onboarding is a system frequently used in the corporate world as a means of orienting incoming employees to their duties and inculcating the workplace values. The program aims to facilitate transition into new work roles and improve employee retention rates. At Montefiore, we have instituted an onboarding curriculum that is given to new anatomic and clinical pathology residents about a month prior to the start of residency. The program includes an introductory video series of basic histology and a series of anatomic and clinical case studies illustrating basic laboratory principles. This didactic content is tagged to learning objectives and short self-assessment modules. In addition, content related to the work ethos at Montefiore and the role of the core competencies and milestones in residency education are included. Finally, a broader component of the onboarding gives the incoming residents a social welcome to our area, including key information about living in the area surrounding Montefiore. The program has been well received by our residents for whom the content has helped to boost confidence when starting. We feel that the program is helpful in ensuring that all incoming residents start having received the same baseline didactic content. Transmitting this didactic content via onboarding allows our residents to begin the work of learning pathology immediately, rather than spending the first weeks of residency covering remedial content such as basic histology. Such a program may be useful to other pathology residencies, most of whom have residents from a range of backgrounds and whose prior exposure to pathology may be limited.

RESUMO

BACKGROUND: The natural history of flock worker's lung (FWL) and longitudinal lung function changes in nylon flock-exposed workers have not been well characterized. METHODS: Symptoms, pulmonary function testing, and chest radiographs from five index cases, subsequent case referrals, and screened employees of a flocking plant in Kingston, Ontario, Canada, were compared and analyzed for changes over time (variable follow-up intervals between 1991 and 2011). RESULTS: Nine cases and 30 flock-exposed workers without FWL were identified. Four cases had persistent interstitial lung disease despite three having left the workplace. Two developed hypoxemic respiratory failure and secondary pulmonary hypertension and died of complications 18 and 20 years after diagnosis, respectively. Five cases resolved after leaving the workplace. Compared with resolved cases, persistent cases had lower diffusing capacity of the lung for carbon monoxide at presentation (P < .05) and follow-up (P < .05). Among exposed workers employed for 14.5 ± 4.7 years, five had abnormal chest radiographs vs none at baseline (P = .001) over 14.8 ± 4.6 years of follow-up. The prevalence of wheeze increased (P = .001), and FEV1/FVC decreased (P < .001). FEV1% predicted was significantly lower at follow-up (P = .05). Average FEV1 decline was 46 mL/year (range, -27 to 151 mL/y). Seventy-seven percent of exposed workers were current or former smokers. CONCLUSIONS: The natural history of FWL includes the following patterns: complete resolution of symptoms; radiographic and pulmonary function abnormalities; permanent, but stable symptoms and restrictive pulmonary function deficits; and progressive decline in pulmonary function, causing death from respiratory failure and secondary pulmonary hypertension. A low baseline diffusing capacity of the lung for carbon monoxide is associated with the persistence and progression of FWL.

RESUMO

An opportunity for low cost, population-based screening has resulted from the recent promotion of blood donor "value-added" testing. We utilized this opportunity to evaluate key data on cardiovascular risk factors (CVRF) obtained from a sample of late adolescents (16 to 19 years old) from generally affluent suburban communities. We examined non-fasting serum cholesterol and glucose, body mass index (BMI), mean arterial pressure (MAP), determined percentile-based values for these variables for the suburban late-teenage population represented by this sample, and examined potential associations among these parameters. Data were obtained on a cohort of 7,464 males and females divided by age and gender. Percentile values at the 25(th), 50(th), 75(th), 95(th) and 97.5(th) levels were calculated by nonparametric methods. Within gender groups, several small but statistically significant differences in CVRF were noted for different ages. In general, levels of CVRF were substantially higher than expected. BMI data were compared with year 2000 United States Centers for Disease Control and Prevention (CDC) norms, and for all age groups and both genders, significantly higher percentile-based values were noted for the adolescents in this study. Elevations in glucose and cholesterol levels associated significantly with MAP and BMI in the older (18 and 19) age groups. We conclude that late adolescents are displaying a disturbing trend toward dangerous levels of CVRF and that teenagers from affluent suburbs are not exempt from this trend. These data also point out the utility of blood donor "value-added" screening programs in this population.
