Pediatric Cranial Dog Bite Injuries: More than Meets the Eye.

CASE PRESENTATION: A six-month-old female presented to a community hospital with small lacerations to the scalp, face, and left eyelid from a dog bite injury. Computed tomography imaging revealed an impacted right frontal bone fracture and left superior orbital fracture, prompting transfer, neurosurgical repair, and infectious disease management of the injury. DISCUSSION: This report highlights the importance of having a high level of suspicion for deeper injury in pediatric and especially infant craniofacial dog bites, obtaining radiographic imaging, and initiating appropriate multidisciplinary triage to prevent life-threatening infection and complications.

Are Outcomes of Temporomandibular Joint Arthroscopy Influenced by Central Sensitization?

PURPOSE: A proportion of subjects with internal derangements of the temporomandibular joint (TMJ) may have a central sensitization disorder that may affect pain perception after surgery. This study aims to estimate the association between fibromyalgianess (FMness) score, a summed score of the Widespread Pain Index (WPI) and Symptom Severity Sore (SSS), and outcomes following TMJ arthroscopy. METHODS: A retrospective cohort study including individuals who received arthroscopy for TMJ internal derangement at Michigan Medicine between 2011 and 2020 was performed. A predictor variable, FMness score, was assigned via the sum of WPI and SSS. Univariate and bivariate analyses were performed. Linear-mixed effects models were used to analyze 6 different outcomes, each in their own model: pain, jaw functional limitation scale (JFLS), JFLS-mobility domain, pain-related disability, comfortable maximum interincisal opening, and active maximum interincisal opening. Covariance structure was selected based on null model fit separately for each outcome. RESULTS: Thirty-one subjects were included in the study sample. Twenty-eight subjects were female. Average age was 45.9 years. Bivariate analysis demonstrated that subject's FMness score was not correlated with pain (b = 0.03 [-0.10, 0.17] P = .59) or JFLS score (b = 1.00 [-.80, 2.81] P = .27). However, subject's FMness score was significant for predicting JFLS-mobility domain score (b = .61, [0.05, 1.18] P = .04). CONCLUSION: A greater extent of central sensitization was associated with lower comfortable mouth opening after surgery, greater limitations in opening wide enough to eat various foods (higher JFLS-mobility scores), and higher pain-related disability. Future studies with larger sample sizes and reconstructive TMJ operations such as total TMJ arthroplasty may help clarify the impact of SSS and WPI scores on outcomes of TMJ surgery.

Lower respiratory tract infections among american Indian and Alaska Native children and the general population of U.S. Children.

BACKGROUND AND OBJECTIVE: Lower respiratory tract infections (LRTIs) cause substantial childhood morbidity. This study characterizes and compares LRTI-associated morbidity among American Indian/Alaska Native (AI/AN) children and the general population of U.S. children. METHODS: Hospitalization and outpatient records with a diagnosis indicating LRTIs were evaluated for children aged younger than 5 years during 1990-2001. RESULTS: For 1999-2001, the LRTI-associated hospitalization rate was significantly higher for AI/AN children than for U.S. children (116.1 versus 63.2/1000, respectively), with the disparity being greater for infants than for 1- to 4-year-old children. Also the rate of LRTI-associated outpatient visits among AI/AN infants was higher than that for all U.S. infants (737.7 versus 207.2/1000, respectively). LRTI hospitalization and outpatient visit rates were highest in the Alaska and Southwest Indian Health Service regions. During 1990-2001, the LRTI hospitalization rate among AI/AN infants in the Alaska region and among the general U.S. infant population increased. Bronchiolitis-associated hospitalization rates increased for AI/AN and U.S. infants, whereas the pneumonia-associated hospitalization rate decreased among AI/AN infants and remained stable among U.S. infants. CONCLUSIONS: LRTIs continue to be an important cause of morbidity in children, especially among AI/AN infants in the Alaska and Southwest regions. Strategies to reduce LRTI hospitalizations and outpatient visits are warranted for all infants, but the greatest potential impact would be among AI/AN infants.

Respiratory syncytial virus hospitalizations among American Indian and Alaska Native infants and the general United States infant population.

OBJECTIVE: To determine the burden of respiratory syncytial virus (RSV) disease among American Indian (AI) and Alaska Native (AN) infants, by examining RSV-associated hospitalizations. METHODS: Infant hospitalizations from 1997 through 2001 with RSV listed as a diagnosis were selected by using Indian Health Service/tribal hospital discharge data for AIs/ANs and National Hospital Discharge Survey data for the general US population. RESULTS: In 2000-2001, RSV disease was listed as a diagnosis for 14.4% of all AI/AN infant hospitalizations, with bronchiolitis attributable to RSV infection (12.2%) being among the top 5 listed diagnoses. The rate of RSV-specific hospitalizations was 34.4 hospitalizations per 1000 infants for AI/AN infants and 27.4 hospitalizations per 1000 births for the general US infant population. The hospitalization rates for AI/AN infants living in the Alaska and Southwest regions (70.9 and 48.2 hospitalizations per 1000 infants, respectively) were much higher than the overall rate for US infants. CONCLUSIONS: RSV infection is one of the leading causes of hospitalization among all infants in the United States, and AI/AN infants living in the Southwest and Alaska regions are at especially high risk for hospitalizations associated with RSV infection. Development of vaccines, antiviral agents, and other strategies to prevent RSV disease could yield substantial public health benefits.
