Change in Columellar-Philtral and Nasolabial Angles Over Time Following Rhinoplasty.

Preoperative analyses of the columellar-philtral and nasolabial angles (CPA and NLA) are important considerations for the rhinoplasty surgeon. This study aims to quantify and compare the degree of change in nasal tip rotation as measured by CPA and NLA over time following rhinoplasty and to identify surgical maneuvers or patient characteristics that may affect nasal tip rotation. Prospective analysis of CPA and NLA in 111 consecutive, consenting cosmetic, and/or functional rhinoplasty patients of the senior author over a 1-year time period was performed. Angles were analyzed before surgery, immediately after surgery, and at 1 week, 1 month, 6 months, and 1 year following surgery. Subgroup analyses based on surgical maneuvers and other covariates were performed. The greatest change to CPA and NLA in the upright position was 11.8 degrees (95% confidence interval [CI]: 9.8-13.7, p < 0.001) and 9.3 degrees (95% CI: 7.9-10.7, p < 0.001) of elevation 1 week after surgery, respectively. The mean CPA was not significantly different than preoperative measures 6 months after surgery; however, the NLA remained 4.94 degrees (95% CI: 2.1-8.4, p = 0.001) elevated. Females showed approximately 10 degrees more elevated CPA than males in pre- and postoperative time points; however, the NLA did not discriminate between sexes. Transfixion incisions appears to cause a significant decrease in postoperative NLA compared with patient who did not undergo transfixion incisions. Measurements for nasal tip rotation are variable and inconsistent throughout the literature. This study shows that rhinoplasty may have a greater effect on nasal tip rotation as measured by NLA and that the effects of NLA and CPA are independent, signifying that a standardized measurement for nasal tip rotation is warranted.

Primary Palate Reconstruction Combined With Cranio-Maxillo-Facial Fixation After Self-Inflicted Gunshot Wound Injury: Critical Incision Planning for Regional Flap Reconstruction.

Self-inflicted gunshot wounds (GSW) to the palate result in complex bony and soft tissue trauma to the mid and upper face. Patients who survive these injuries are faced with significant speech and feeding difficulties. Upper and midface fractures open reduction and internal fixation (ORIF) is required for many of these patients, and consideration to incision planning is critical in order to preserve a primary option for oroantral fistula repair. The temporoparietal fascia (TPF) flap is an excellent option for primary palate repair as it is often exposed in the operative field during facial fracture ORIF and can be readily used for this purpose if its blood supply and width is not inadvertently compromised while making a temporal incision. This flap is easy to elevate, does not require any microvascular expertise, and using the TPF to reconstruct the palate injury primarily may save the patient years of wearing an obturator and/or subsequent trips to the OR for operative fistula management. In contrast to the temporalis muscle flap, this flap does not create temporal hollowing after elevation, which is a significant aesthetic complaint among patients. Proper incision planning is critical to preserve this flap as an option for palate fistula repair as the fascial layer is often incised when making coronal incisions. Primary repair of palate injuries using the TPF flap at the same time as upper facial ORIF has very little morbidity in this setting, and greatly augments patients' quality of life.

Diagnosis disclosure, medication hiding, and medical functioning among perinatally infected, HIV-positive children and adolescents.

Little is known about the immunological and virological impact of diagnosis disclosure among HIV-positive children and adolescents. The current cross-sectional study examined medication hiding as a mediator of the relationship between disclosure to friends and three medical outcomes: CD4+ absolute count, CD4+ percentage, and viral load. Participants included 25 perinatally infected, HIV-positive children and adolescents ages 11-18 years from the US. Diagnosis disclosure and medication hiding were self-reported by participants and medical markers were derived from blood samples drawn during the same clinic visit. Bootstrapping analyses revealed that disclosure to at least one friend (versus no friends) was associated with less medication hiding, which was associated with higher CD4+ absolute counts and percentages but not viral load. Further, among the subset of participants who had disclosed to at least one friend (n = 19), those who reported disclosing to 11 or more versus 1-10 friends were less likely to hide medication taking, which was associated with higher CD4+ absolute counts. Findings suggest HIV-positive children and adolescents' diagnosis disclosure to friends corresponds to less medication hiding, ultimately yielding better immune functioning. Health care providers should be cognizant of these potential medical benefits associated with disclosure when offering support around disclosure decision-making.

Rhinoplasty in a 3 Week Old: Surgical Challenges in the Setting of Severe Congenital Frontonasal Dysplasia.

OBJECTIVES: Congenital frontonasal dysplasia (CFND) is a rare heterogeneous collection of facial deformities. Due to the range of complexity, surgical management is not standardized. METHODS: We present a severe case of CFND and approach to managing multiple defects with a focus on rhinoplasty. RESULTS: This infant was born full term with a large mass instead of a nose, a bilateral cleft lip and palate, and hypertelorbitism. Our primary concerns initially were to address communication with the intracranial cavity, preserve a nasal lining, and improve nasal appearance and airway function in the short term without interfering with subsequent rhinoplasty and adult nasal appearance. CONCLUSIONS: This complex case of CFND is more severe than anything we encountered in our literature review and demonstrates the necessity for multidisciplinary approach to multiple craniofacial defects. Future plans for this patient include rhinoplasty with auricular graft, scar revision, and addressing tip support.

Mucus concentration-dependent biophysical abnormalities unify submucosal gland and superficial airway dysfunction in cystic fibrosis.

Cystic fibrosis (CF) is characterized by abnormal transepithelial ion transport. However, a description of CF lung disease pathophysiology unifying superficial epithelial and submucosal gland (SMG) dysfunctions has remained elusive. We hypothesized that biophysical abnormalities associated with CF mucus hyperconcentration provide a unifying mechanism. Studies of the anion secretion-inhibited pig airway model of CF revealed elevated SMG mucus concentrations, osmotic pressures, and SMG mucus accumulation. Human airway studies revealed hyperconcentrated CF SMG mucus with raised osmotic pressures and cohesive forces predicted to limit SMG mucus secretion/release. Using proline-rich protein 4 (PRR4) as a biomarker of SMG secretion, CF sputum proteomics analyses revealed markedly lower PRR4 levels compared to healthy and bronchiectasis controls, consistent with a failure of CF SMGs to secrete mucus onto airway surfaces. Raised mucus osmotic/cohesive forces, reflecting mucus hyperconcentration, provide a unifying mechanism that describes disease-initiating mucus accumulation on airway surfaces and in SMGs of the CF lung.

Long-term corticosterone treatment induced lobe-specific pathology in mouse prostate.

BACKGROUND: Glucocorticoids influence prostate development and pathology, yet the underlying mechanisms including possible direct glucocorticoid effect on the prostate are not well characterized. METHODS: We evaluated the expression of the glucocorticoid receptor (GR) together with the effects of supraphysiological glucocorticoid (corticosterone) on mouse prostate morphology and epithelial proliferation. Mature male mice were treated by weekly subdermal implantation of depot pellets containing either 1.5 mg corticosterone or placebo providing steady-state release for 4 weeks. RESULTS: Corticosterone treatment significantly increased dorsolateral and anterior prostate weights as well as prostate epithelial cell proliferation while epithelial apoptosis remained low upon corticosterone treatment. Histological analysis of the anterior lobe demonstrated abnormal, highly disorganized luminal epithelium with frequent formation of bridge-like structures lined by continuous layer of basal cells not observed following placebo treatment. Molecular analysis revealed corticosterone-induced increase in expression of stromal growth factor Fgf10 which, together with prominent stromal GR expression, suggest that glucocorticoid modify stromal-to-epithelial signaling in the mouse prostate. The mitogenic effects were prostate specific and not mediated by systemic effects on testosterone production suggesting that corticosterone effects were primarily mediated via prostate GR expression. CONCLUSION: These data demonstrate that murine prostate is significantly and directly influenced by corticosterone treatment via aberrant stromal-to-epithelial growth factor signaling.

Incidence and Mechanisms of Musculoskeletal Injuries in Deployed Navy Active Duty Service Members Aboard Two U.S. Navy Air Craft Carriers.

INTRODUCTION: This brief report describes the number and nature of cases of musculoskeletal pain and injury among sailors and marines presenting to the ship's physical therapist during recent, respective deployments of two U.S. Navy aircraft carriers. MATERIALS AND METHODS: The case definition for this study was cases of work-limiting medical complaints involving the musculoskeletal system presenting, or referred, to the ship's physical therapy services for evaluation and treatment. The population for this study was drawn from ship's company from two Nimitz class carriers on their respective deployments. Potential subjects were recruited at their index visit for their complaint. Participants completed a survey of their symptoms while at the ship's medical department. Data for analysis consist of counts of cases, body part affected, self-reported mechanism of injury, age, and gender of the subject. Data were analyzed by generating descriptive tables. RESULTS: One hundred ninety-seven cases were captured across the two carriers. Injury to the low back was the most frequent (34%), followed by shoulder (25%) and knee (15%). Twenty one cases (11%) were reported to be exacerbation of previous injuries and the rest new injuries. Of the 176 new injury cases, 93 (53%) were of an insidious onset and the remainder had a specific, identifiable onset. Of the 82 cases with a specific identifiable onset, 38 cases (46%) occurred during participation in sport and exercise activity on board ship, and the remainder of the cases occurred during the performance of duty-related work. None of the cases required evacuation off of the ship. CONCLUSION: Care should be used interpreting the results since participants were volunteers and a small proportion of eligible subjects chose not to participate in the study. Nevertheless, our data are generally consistent with other studies of musculoskeletal injury on board U.S. Navy ships and are useful for health care planning purposes and for planning for future studies that may take place on board U.S. Navy vessels. The novel and important finding of this study suggests that sports and exercise activity on board ship may warrant a new area of attention for safety.

Congenital infantile fibrosarcoma of the glabella: Nuances of achieving surgical cure without cosmetic or functional deformity.

Congenital Infantile Fibrosarcoma is a rare neoplasm that typically presents during the first year of life, but uncommonly in the head and neck. We report a six-day old male presenting with an expanding mass of the right glabella associated with visual field obstruction. The patient underwent a two-staged procedure for surgical removal of the tumor due to the initially unclear pathologic diagnosis of the tumor, combined with the desire to close the defect while incurring minimal aesthetic or functional deformity. We describe this patient's postnatal presentation and curative surgical management and review the relevant literature to date.

Autologous Fat Grafting Restores Soft-tissue Contour Deformities after Vascular Anomaly Surgery.

BACKGROUND: Soft-tissue loss is expected after resection of large vascular lesions. Autologous fat transfer improves asymmetries; however, systematic outcomes are not previously described for vascular anomaly reconstruction. METHODS: Retrospective chart review from 2012 to 2015 included patients receiving autologous fat transfers for soft-tissue defects during or following vascular anomaly surgery at a tertiary care center. Patients received dermal en bloc fat grafts, lipoaspirates, or both. Pre- and postoperative photographs were blindly reviewed by 3 facial plastic surgeons using a 5-point scale. Dermal abdominal en bloc fat grafts were placed immediately after excision of a vascular anomaly. Lipoaspirate fat grafting was performed using liposuction (modified Coleman technique) and centrifugation. The effectiveness of fat transfers was assessed using patients' photographs. Final follow-up was 6 months to 5 years. RESULTS: There were 35 autologous fat transfer surgeries in 27 patients. Fourteen patients received en bloc dermal fat grafts (14 total), 13 lipoaspirate transfers (21 total), and 3 both. Ages ranged from 2 to 69 years (mean = 25 years). Majority of patients (81%) had head and neck lesions. Average volume of fat injected was 16.5 mL (range 0.8-100 mL). The average observer rating score was 2.45 [1-5 (5-point scale)] in the en bloc fat graft group versus 3.83 in the lipoaspirate group (P < 0.0001) with acceptable inter-rater reliability between 3 observers (coefficient of concordance = 0.76). Follow-up ranged from 6 months to 5 years. There were 2 complications in the dermal fat graft group and none in the lipoaspirate group. CONCLUSIONS: Autologous fat transfer improves symmetry and scarring after surgical treatment of vascular anomalies. Fat grafting is permanent and reliable and creates a more symmetric soft-tissue contour compared with dermal fat grafts.

Single parents of children with chronic illness: an understudied phenomenon.

OBJECTIVE: To examine the chronic illness literature and evaluate the impact on single parenting and children and adolescents with chronic illness. METHODS: We conducted literature reviews of relevant research pertaining to single-parent families on PubMed, Medline, and PsychINFO and also surveyed pertinent book chapters and all of the articles from the Journal of Pediatric Psychology since 1987 for articles, specifically examining the potential associations of single (lone) parenting versus two-parent households on children's psychosocial functioning and the impact of the child's illness on caregiver functioning. RESULTS: While the literature has examined and discussed the stressors associated with parenting a child with an illness, including the impact of illness on finances, family roles, and caregiver burden, few studies have examined single parents of children and adolescents with chronic illnesses and related stressors stemming from being a lone caregiver. CONCLUSIONS: There is a dearth of studies examining the association between lone parenting and psychosocial functioning among children and adolescents with chronic illnesses. Specific questions necessitating future investigation are summarized and recommendations are made for future research in this important area of inquiry.

Feasibility of Training Physical Therapists to Implement a Psychologically Informed Physical Therapy Program for Deployed U.S. Sailors and Marines with Musculoskeletal Injuries.

This study assesses the feasibility of training U.S. Navy Physical Therapy staff members (PT staff) aboard a U.S. Navy Aircraft Carrier in psychologically informed physical therapy (PiPT). Training was conducted prior to deployment over 3 d and included background information, skills development, and application in the form of role playing and case studies. During deployment, nine phone conferences were conducted to reinforce training, assess skills, and discuss implementation. PiPT knowledge was assessed by a written test and role-playing skills. The adoption of the training was determined by analysis of clinical notes and verbal responses of the PT staff during phone conferences. There were two PT staff members on the carrier. Both received passing knowledge test scores and demonstrated role-playing proficiency. Clinical note assessment and discussions during conference calls also indicated successful implementation. The feasibility of training Navy PT staff to implement PiPT was demonstrated. PT staff successfully translated training into practice. This is significant, since PiPT has the potential to limit attrition due to musculoskeletal injuries in Navy personnel. Factors believed to be associated with the success of the training include adoption of the PiPT model by PT staff and reinforcement of changes in clinical practice during deployment.

The Temporalis Muscle Flap for Palate Reconstruction: Case Series and Review of the Literature.

Introduction The temporalis myofascial (TM) is an important reconstructive flap in palate reconstruction. Past studies have shown the temporalis myofascial flap to be safe as well as effective. Free flap reconstruction of palate defects is also a popular method used by contemporary surgeons. We aim to reaffirm the temporalis myofascial flap as a viable alternative to free flaps for palate reconstruction. Objective We report our results using the temporalis flap for palate reconstruction in one of the largest case series reported. Our literature review is the first to describe complication rates of palate reconstruction using the TM flap. Methods Retrospective chart review and review of the literature. Results Fifteen patients underwent palate reconstruction with the TM flap. There were no cases of facial nerve injury. Five (33%) of these patients underwent secondary cranioplasty to address temporal hollowing after the TM flap. Three out of fifteen (20%) had flap related complications. Fourteen (93%) of the palate defects were successfully reconstructed, with the remaining case pending a secondary procedure to close the defect. Ultimately, all of the flaps (100%) survived. Conclusion The TM flap is a viable method of palate defect closure with a high defect closure rate and flap survival rate. TM flaps are versatile in repairing palate defects of all sizes, in all regions of the palate. Cosmetic deformity created from TM flap harvest may be addressed using cranioplasty implant placement, either primarily or during a second stage procedure.

The Tissue Expander Effect in Early Surgical Management of Select Focal Infantile Hemangiomas.

IMPORTANCE: The current standard of treatment for infantile hemangiomas (IHs) involves initial observation for regression throughout infancy and childhood, with or without medical management with ß-blocker medications. Approximately 50% of the lesions respond almost completely to this regimen. However, the remaining 50% of the lesions, especially established focal IHs of the lip, nose, eyelids, forehead, cheek, and scalp, do not regress completely with this regimen or do so leaving a deformity; among these lesions, early surgical management may result in a superior aesthetic and functional outcome. OBJECTIVE: To identify select focal head and neck lesions of IH that will likely not completely involute with medical management and that are ideal for a 1-stage surgical excision. DESIGN, SETTING, AND PARTICIPANTS: In this case series, records of infants and children presenting to a tertiary care vascular anomalies center for management of IHs by the senior author were reviewed. Representative examples of focal IHs of the lips, nose, eyelids, cheek, and glabella demonstrating the tissue expansion effect were selected for presentation. Expert opinion based on more than 20 years of experience of the senior surgeon treating more than 2000 patients with focal IH and long-term clinical follow-up is also provided. MAIN OUTCOMES AND MEASURES: Eradication of the IH while restoring aesthetic form and function to the face. RESULTS: Five examples of patients with focal IHs of the lip, nose, eyelid, cheek, and glabella demonstrating the tissue expander effect who were successfully treated with surgery are presented. The 5 patients with these lesions ranged in age from 3 months to 5 years old, and all of them were female. One of these patients was treated with ß-blockers, and another with steroids, with incomplete response to treatment prior to undergoing surgery. The tissue expander effect of a focal IH on adjacent, unaffected tissue facilitated excision of the lesion and primary closure without distortion of anatomical subunits in all 5 of these cases. Improved cosmesis with either improved or unaffected function was demonstrated. CONCLUSIONS AND RELEVANCE: Clinicians should consider early surgical intervention in infants with select focal infantile hemangiomas in lieu of prolonged observation or medical management. The psychological benefit of early removal of these disfiguring lesions has not been quantified, but is subjectively apparent to clinicians and the families of patients. Furthermore, the costs and unknown long-term sequelae of ß-blocker medication, which is the current standard of treatment for IHs along with observation for regression, have not yet been quantified but will gain increasing salience in the current medical climate. LEVEL OF EVIDENCE: 5.

Influence of glucocorticoids on human osteoclast generation and activity.

UNLABELLED: Using human peripheral blood mononuclear cells as osteoclast precursors, we showed that dexamethasone stimulated osteoclast generation at a pharmacological concentration but did not affect the life span of human osteoclasts. Dexamethasone also dose-dependently increased signals for osteoclastogenesis. INTRODUCTION: Glucocorticoid-induced osteoporosis is a common and serious disease. Glucocorticoids predominantly affect osteoblast proliferation and life span. Much of the bone loss is caused by reduced bone formation, but there is also an element of increased bone resorption. MATERIALS AND METHODS: Human peripheral blood mononuclear cells were cultured on whale dentine and induced to differentiate to osteoclasts by RANKL and human macrophage-colony stimulating factor (M-CSF). Osteoclast activity was quantified by pit area. RANKL and osteoprotegerin (OPG) expression in osteoblasts were measured by real-time RT-PCR. RESULTS: In the early phase of osteoclast generation (0-16 days), cultures from two different donors showed that dexamethasone at 10(-8) M increased pit area by 2.5-fold, whereas lower concentrations had no effect. At the highest dexamethasone concentration (10(-7) M), pit area was reduced. In 21-day cultures from three other donors, a similar increase was seen with dexamethasone at 10(-8) M. There was, however, no evidence of increased life span of osteoclasts with dexamethasone. In human primary osteoblasts, dexamethasone dose-dependently reduced OPG and increased RANKL expression as measured by quantitative real time RT-PCR. CONCLUSION: These data provide some explanation at a cellular and molecular level for the observed increase in bone resorption seen in patients treated with glucocorticoids and indicate that there are clear direct effects of glucocorticoids on bone resorption in human cell systems that may differ from other species.

Streamlined bilateral otologic surgery: how I do it.

Bilateral simultaneous otologic surgery is being performed more commonly among otologists. The benefits of performing bilateral simultaneous cochlear implants in the pediatric population, in particular, have become increasingly recognized as the safety and efficacy of this operation have been recognized in the literature. Here we present a streamlined method of performing bilateral simultaneous otologic surgery that emphasizes midline placement of facial nerve electrodes and a method of sterile preparation and draping that affords direct exposure to both ears at one time, without the need to turn the head or adjust the drapes multiple times throughout the operation. Our approach facilitates frequent and efficient alternation between ears throughout the operation, optimizing efficiency of motion and instrumentation for the surgeon, and reducing overall operative and general anesthesia time for the patient.

Probable Immunoglobulin Subtype-G4-Related Disease in the Head and Neck from Foreign Body Injection: A Case Report.

Introduction Immunoglobulin subtype G4-related disease (IgG4-RD) is a fibroinflammatory disease of unknown etiology, with manifestations involving nearly every organ system. Its association with foreign bodies is not established. Here, we present a novel case of IgG4-RD in response to foreign body injection. Case Description A 58-year-old woman presented with history of persistent left facial pain, xerophthalmia, blurred vision, and trismus. The patient's medical history was significant for left-sided temporomandibular joint (TMJ) reconstruction with silicone injection into the joint. Magnetic resonance imaging revealed a lesion in the left skull base. Biopsies demonstrated the cardinal histopathological features of IgG4-RD. The patient was treated with a tapering dose of prednisolone followed by rituximab, resulting in tumor shrinkage and resolution of her symptoms. Discussion This is the first reported case of IgG4-RD potentially precipitated by a foreign body, in this case injected silicone into the TMJ. The pathogenesis and etiology of IgG4-RD is still not fully elucidated, but allergic and reactive inflammatory reactions have been implicated in the disease process. This case report should raise the idea of reactive foreign bodies as a causative agent for IgG4-RD.

Biomechanical properties of superficial musculoaponeurotic system tissue with vs without reinforcement with poly-4-hydroxybutyric acid absorbable mesh.

IMPORTANCE It is unknown whether poly-4-hydroxybutyric acid (P4HB)-reinforced superficial musculoaponeurotic system tissue (SMAS) plication techniques will support SMAS imbrication and plication and potentially improve outcomes in rhytidectomy. OBJECTIVES To evaluate the biomechanical properties (tissue breaking strength, suture tearing force, and stress relaxation) of the SMAS with vs without reinforcement with P4HB absorbable mesh and to correlate these results with potential clinical applications. DESIGN, SETTING, AND SAMPLES In a cadaver study at an academic setting, 12 fresh frozen cadaver heads were used. Rhytidectomy incisions were made, and the SMAS was harvested and prepared for strength and stress testing using an Instron device. MAIN OUTCOMES AND MEASURES Tissue breaking strength and suture tearing force were analyzed. Stress relaxation test results were also assessed. The results of the SMAS samples alone were compared with those reinforced with P4HB absorbable mesh. RESULTS Overall, there were significant differences noted in tissue breaking strength and suture tearing force between the 2 groups. When the SMAS was reinforced with absorbable mesh, significant improvements were observed in tissue breaking strength (P < .001) and suture tearing force (P < .003). In addition, less variability was demonstrated in the maximum tensile load-bearing quality of the SMAS when the repair was reinforced with P4HB. CONCLUSIONS AND RELEVANCE Reinforcement with P4HB absorbable mesh improves tissue breaking strength and suture tearing force in cadaveric SMAS. It also reduces the variability in load vs displacement seen among samples tested. These data suggest that P4HB-reinforced SMAS imbrication would support higher loads and provide more consistent, long-lasting SMAS support among patients undergoing rhytidectomy. Further studies are needed to correlate these data with clinical outcomes in rhytidectomy.

Multilevel airway obstruction including rare tongue base mass presenting as severe croup in an infant.

Laryngomalacia is the most common cause of neonatal stridor, accounting for up to 60% of cases [1]. Less common causes of neonatal stridor include subglottic or tracheal stenosis, or congenital masses of the upper airway. Neonates with an identified congenital etiology of symptomatic upper airway obstruction often have synchronous airway lesions leading to multilevel airway obstruction. These infants deserve an endoscopic evaluation to better diagnose and manage respiratory distress. Here we present a rare case of an infant initially diagnosed with croup, but ultimately found to have multilevel airway obstruction including severe laryngomalacia and an obstructing tongue base mass.

Neurodevelopmental deficits among infants and toddlers with sickle cell disease.

OBJECTIVE: Neurodevelopmental deficits are among the serious complications of sickle cell disease (SCD). However, few studies have prospectively evaluated neurodevelopmental deficits in very young children with SCD. We analyzed baseline neurodevelopmental data from a cohort of 80 infants and toddlers with SCD to identify primary disease-related events and sociodemographic risk factors associated with early developmental delay. METHODS: This is an analysis of baseline date of a 4-year mixed, cross-sectional/longitudinal study. Full-term children at age 3.5 years or younger with SCD (any genotype) were eligible. Neurodevelopmental evaluations (Bayley II) were conducted at ages 9, 15, 21, 30, and 40 months. Demographics, hematologic variables, and medical events were obtained. RESULTS: Significant neurodevelopmental deficits were evident: 17.5% scoring >2SD below the mean on Bayley Mental Index or Motor Index. Odds ratio of significant developmental delay was >9 times more likely among those who had experienced vaso-occlusive pain episodes, after controlling for socioeconomic status (SES), gender, pneumonia/acute chest syndrome, and hemoglobin concentration. Male gender was also a risk factor for developmental delay. CONCLUSIONS: Early cognitive and motor delays were present in young children with SCD, with higher prevalence among those who had experienced pain crises. Increased vulnerability of male gender is consistent with other at-risk populations but has not been previously addressed in SCD research. Furthermore, these delays are not sufficiently explained by lower SES. Significant developmental delay in children with SCD may go unrecognized by primary care practices, medical specialty clinics, or parents. The importance of routine neurodevelopmental assessment for children with chronic medical conditions is clear.

Disparities in head and neck cancer: assessing delay in treatment initiation.

OBJECTIVES/HYPOTHESIS: Disparities in outcome for head and neck cancer (HNC) treatment are related to diverse factors including tumor stage, socioeconomic status, and treatment compliance. Latency to initiation of therapy may contribute to worse outcomes for underserved populations. The objectives of this study were to measure the interval from diagnosis of HNC to initiation of cancer treatment (DTI) and to identify factors that prolong DTI. STUDY DESIGN: Retrospective study. METHODS: We identified 150 consecutive patients treated for squamous cell HNC at a tertiary-care public hospital between 2005 and 2007. Outcome measures used were 1) interval between cancer diagnosis and treatment initiation and 2) factors that predict prolonged DTI. RESULTS: We included 100 patients in the analysis. Median time to perform biopsy was 8 days; time to obtain final diagnosis was 14 days; time to complete staging scans was 18 days; time to discuss treatment plan was 23 days; time to initiation of therapy was 56 days. Median DTI was 48 days. DTI was prolonged for patients receiving primary radiotherapy compared to surgical therapy: 57 versus 30 days (P < .001). Early stage tumors had shorter DTI than late-stage tumors: 38 versus 57 days (P = .02). Presenting with outside biopsy demonstrating HNC also reduced DTI (P = .03). Obtaining a computed tomography scan in the emergency department was not found to significantly affect DTI. CONCLUSIONS: DTI was found to be prolonged among HNC patients in this study when compared to previously published treatment intervals. Advanced stage of tumor, primary radiotherapy, and need for biopsy prolonged DTI. Future studies should better identify causes of delay and reduce latency for patients at highest risk for delay.
