Family Characteristics Associated With Child Maltreatment Across the Deployment Cycle of U.S. Army Soldiers.

OBJECTIVE: Soldier deployment can create a stressful environment for U.S. Army families with young children. Prior research has identified elevated rates of child maltreatment in the 6 months immediately following a soldier's return home from deployment. In this study, we longitudinally examine how other child- and family-level characteristics influence the relationship of deployment to risk for maltreatment of dependent children of U.S. Army soldiers. METHODS: We conducted a person-time analysis of substantiated reports and medical diagnoses of maltreatment among the 73,404 children of 56,087 U.S. Army soldiers with a single deployment between 2001 and 2007. Cox proportional hazard models estimated hazard rates of maltreatment across deployment periods and simultaneously considered main effects for other child- and family-level characteristics across periods. RESULTS: In adjusted models, maltreatment hazard was highest in the 6 months following deployment (hazard ratio [HR] = 1.63, p < 0.001). Children born prematurely or with early special needs independently had an increased risk for maltreatment across all periods (HR = 2.02, p < 0.001), as well as those children whose soldier-parent had been previously diagnosed with a mental illness (HR = 1.68, p < 0.001). In models testing for effect modification, during the 6 months before deployment, children of female soldiers (HR = 2.22, p = 0.006) as well as children of soldiers with a mental health diagnosis (HR = 2.78, p = 0.001) were more likely to experience maltreatment, exceeding the risk at all other periods. CONCLUSIONS: Infants and children are at increased risk for maltreatment in the 6 months following a parent's deployment, even after accounting for other known family- and child-level risk factors. However, the risk does not appear to be the same for all soldiers and their families in relation to deployment, particularly for female soldiers and those who had previously diagnosed mental health issues, for whom the risk appears most elevated before deployment. Accounting for the unique needs of high-risk families at different stages of a soldier's deployment cycle may allow the U.S. Army to better direct resources that prevent and address child maltreatment.

Under-ascertainment from healthcare settings of child abuse events among children of soldiers by the U.S. Army Family Advocacy Program.

In cases of maltreatment involving children of U.S. Army service members, the U.S. Army Family Advocacy Program (FAP) is responsible for providing services to families and ensuring child safety. The percentage of cases of maltreatment that are known to FAP, however, is uncertain. Thus, the objective of this retrospective study was to estimate the percentage of U.S. Army dependent children with child maltreatment as diagnosed by a military or civilian medical provider who had a substantiated report with FAP from 2004 to 2007. Medical claims data were used to identify 0-17year old child dependents of soldiers who received a medical diagnosis of child maltreatment. Linkage rates of maltreatment medical diagnoses with corresponding substantiated FAP reports were calculated. Bivariate and multivariable analyses examined the association of child, maltreatment episode, and soldier characteristics with linkage to substantiated FAP reports. Across 5945 medically diagnosed maltreatment episodes, 20.3% had a substantiated FAP report. Adjusting for covariates, the predicted probability of linkage to a substantiated FAP report was higher for physical abuse than for sexual abuse, 25.8%, 95% CI (23.4, 28.3) versus 14.5%, 95% CI (11.2, 17.9). Episodes in which early care was provided at civilian treatment facilities were less likely to have a FAP report than those treated at military facilities, 9.8%, 95% CI (7.3, 12.2) versus 23.6%, 95% CI (20.8, 26.4). The observed low rates of linkage of medically diagnosed child maltreatment to substantiated FAP reports may signal the need for further regulation of FAP reporting requirements, particularly for children treated at civilian facilities.

Effects of Noxious Electrical Stimulation and Eccentric Exercise on Pain Sensitivity in Asymptomatic Individuals.

BACKGROUND: Achilles tendinopathy is a common overuse injury in running and jumping athletes. Currently, we do not understand why some conservative interventions (eg, noxious electrical stimulation and eccentric training) may reduce the pain associated with tendinopathy. OBJECTIVE: To determine whether noxious electrical stimulation (NES) or eccentric contractions would alter pain sensitivity around the asymptomatic Achilles tendon. DESIGN: A double-blind trial with block-randomization by gender into 3 intervention arms: NES, eccentric contractions, or low-intensity cycling. PARTICIPANTS: A total of 40 volunteers with no current pain conditions started the study, and 39 completed follow-up testing. METHODS: Participants underwent 2 baseline sessions to assess pain sensitivity response stability of pressure pain threshold (PPT), heat pain threshold (HPT), and heat temporal summation (HTS) over the Achilles tendon. Immediately after the second baseline session, participants performed 1 session of an intervention and were tested immediately postintervention and the next morning. Eccentric-only plantarflexor exercise was performed (4 sets of 15 repetitions) using full bodyweight and slow, 5-second contractions. Noxious electrical stimulation was applied to the Achilles for 20 minutes and dosed to the subjects' pain tolerance. Low-intensity cycling was dosed (60-70 W for 20 minutes) to minimize occurrence of exercise-induced hypoalgesia. The PPT was the primary outcome measure. RESULTS: For PPT, both NES (P < .001) and eccentric (P = .003) groups were less sensitive to pressure immediately posttreatment, and the eccentric group maintained this effect through the next morning (P = .043). No group differences were seen for HPT, but the NES (P = .031) and eccentric (P = .036) groups had less HTS the next morning. CONCLUSIONS: A single session of eccentric exercise and NES can produce immediate and next-day reductions in pain sensitivity in asymptomatic adults. The immediacy of these effects points toward a neurophysiologic mechanism. Future research needs to be performed in clinical populations and to assess any cumulative effects to repetitive intervention.

Differential Child Maltreatment Risk Across Deployment Periods of US Army Soldiers.

OBJECTIVES: We described the risk for maltreatment among toddlers of US Army soldiers over different deployment cycles to develop a systematic response within the US Army to provide families appropriate supports. METHODS: We conducted a person-time analysis of substantiated maltreatment reports and medical diagnoses among children of 112,325 deployed US Army soldiers between 2001 and 2007. RESULTS: Risk of maltreatment was elevated after deployment for children of soldiers deployed once but not for children of soldiers deployed twice. During the 6 months after deployment, children of soldiers deployed once had 4.43 substantiated maltreatment reports and 4.96 medical diagnoses per 10,000 child-months. The highest maltreatment rate among children of soldiers deployed twice occurred during the second deployment for substantiated maltreatment (4.83 episodes per 10,000 child-months) and before the first deployment for medical diagnoses of maltreatment (3.78 episodes per 10,000 child-months). CONCLUSIONS: We confirmed an elevated risk for child maltreatment during deployment but also found a previously unidentified high-risk period during the 6 months following deployment, indicating elevated stress within families of deployed and returning soldiers. These findings can inform efforts by the military to initiate and standardize support and preparation to families during periods of elevated risk.

Sequence of recovery during the course of emergence from the minimally conscious state.

OBJECTIVE: To document and examine recovery profiles of persons during the course of emergence from a minimally conscious state (MCS) after traumatic brain injury (TBI). DESIGN: Case series. SETTING: Participants in an inpatient brain injury rehabilitation program. PARTICIPANTS: Nine people with TBI who emerged from MCS. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: The Western Neuro Sensory Stimulation Profile. RESULTS: In all cases, stereotyped (nonreflexive) movement was the first behavior to resolve, yet by itself it was never sufficient to indicate emergence from the MCS. Two of the 9 patients showed consistent object manipulation before all 3 elements of functional communication. Conversely, in 2 patients, all 3 components of functional communication emerged before object manipulation. In the remaining 5 patients, object manipulation occurred along with components of functional communication. CONCLUSIONS: During the course of data collection, issues were raised about differentiation between the MCS and posttraumatic amnesia. The data are also discussed within the context of the work of Giacino et al and the development of their scale to measure duration of the MCS. These data support the theory that functional communication and object manipulation are the 2 key indicators of emergence from MCS.

Familial cavitary optic disk anomalies: clinical features of a large family with examples of progressive optic nerve head cupping.

PURPOSE: To describe a multigenerational family with autosomal dominant inheritance of cavitary optic nerve head (ONH) anomalies and abnormal ONH vasculature. DESIGN: Description of a single family with inherited eye disease. METHODS: A four-generation pedigree was investigated. Examination included visual acuity, slit-lamp biomicroscopy, intraocular pressure (IOP) measurement, and ophthalmoscopy. Visual fields and fundus photography were obtained when possible. RESULTS: Seventeen clinically affected individuals and two obligate carriers were identified. Most (64.7%) affected persons had bilateral involvement. Visual acuity in affected eyes ranged from 20/20 to no light perception. Although the appearance of affected nerves varied greatly, most lacked a well-formed central retinal artery and instead had multiple radial cilioretinal arteries. Prominent cupping was seen in most affected nerves. Four individuals for whom information was available were treated for glaucoma, but none had documented elevated IOP. Four eyes of two patients demonstrated progressive ONH cupping at normal IOPs. Nine (56.3%) of the 16 individuals for whom we had data had evidence of serous macular detachments; five of these had bilateral macular disease. CONCLUSIONS: A large family with autosomal dominant inheritance of cavitary ONH anomalies and abnormal vasculature is presented. Clinical phenotypes varied markedly. Progressive ONH cupping was documented in four eyes of two patients. Genetic linkage analysis of this family has identified the chromosomal location of a gene responsible for ONH development. This may provide insight into the pathogenesis of glaucomatous ONH damage.

Complement factor H polymorphism p.Tyr402His and cuticular Drusen.

OBJECTIVE: To determine the histidine frequency in patients with the cuticular drusen phenotype of age-related macular degeneration (AMD). METHODS: Fifty individuals were identified who met the criteria for the cuticular drusen phenotype using a standard threshold photograph. We genotyped DNA samples using a polymerase chain reaction-based restriction digest assay. Seven hundred individuals with typical AMD and 252 controls were also genotyped. Fisher exact test was used to analyze the significance of allele frequency differences. RESULTS: The histidine variant was present in 70% (frequency +/- SE, 0.70 +/- 0.05) of the cuticular cohort, 55% (frequency +/- SE, 0.55 +/- 0.01) of the more typical AMD cases, and 34% (frequency +/- SE, 0.34 +/- 0.02) of controls. The association between the cuticular drusen phenotype and the histidine allele was highly significant (P = .003; odds ratio, 2.0; 95% confidence interval, 1.21-3.07; vs AMD cases P<.001; odds ratio 4.54; 95% confidence interval, 2.79-7.50; vs controls). Genotype distribution between the 3 groups was similarly significant (P<.001). CONCLUSION: The cuticular drusen phenotype is highly associated with the Tyr402His variant of the complement factor H (CFH) gene. The significantly higher histidine allele frequency in this group compared with the typical AMD cohort suggests that the complement cascade may play a greater role in the pathogenesis of the cuticular drusen subtype than in AMD as a whole. CLINICAL RELEVANCE: The c.1204T>C, p.Tyr402His allelic variant in the CFH gene is associated with a 3-fold increased risk for AMD. A high frequency of the histidine allele has also been noted in patients with membranoproliferative glomerulonephritis type II.

Novel de novo mutation in a patient with Best macular dystrophy.

OBJECTIVE: To report a novel de novo vitelliform macular dystrophy (VMD2) mutation in a patient with Best macular dystrophy. METHODS: Best-corrected visual acuity, dilated fundus examination, and electro-oculography were performed in a patient with Best macular dystrophy and his parents. Both the patient and his parents also had blood samples drawn, and their DNA was analyzed by direct genomic sequencing. RESULTS: A heterozygous VMD2 gene missense mutation in exon 2 (Thr6Ala [ACA>GCA]) was identified in the proband. This mutation was not present in his clinically unaffected parents. CONCLUSIONS: A novel de novo mutation in the VMD2 gene was found in a patient whose phenotype and electro-oculographic findings were characteristic of Best macular dystrophy, whereas both parents were phenotypically and genetically unaffected. The findings in this family document that a de novo mutation needs to be considered when an isolated family member is found to have a Best disease phenotype.

The minimally conscious state and recovery potential: a follow-up study 2 to 5 years after traumatic brain injury.

OBJECTIVE: To document recovery in persons who were in the minimally conscious state (MCS) for at least 1 month after traumatic brain injury (TBI). DESIGN: Patient series. SETTING: Participants who had been discharged from an inpatient rehabilitation unit. PARTICIPANTS: Eighteen people with TBI and their relatives. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Western Neuro Sensory Stimulation Profile, Disability Rating Scale (DRS), FIM instrument, Dementia Rating Scale, and Sydney Psychosocial Reintegration Scale (SPRS). RESULTS: Level of functioning at follow-up varied from extremely severe disability or greater on the DRS (n=4) to mild disability (n=1). These outcomes were corroborated by results of the FIM and the Dementia Rating Scale. All participants experienced some (44%) or major (56%) change in their level of psychosocial functioning on the SPRS compared with their preinjury level. There were no significant correlations between duration of time in the MCS and outcome on FIM, DRS, or SPRS. CONCLUSIONS: These results highlight the heterogeneity of outcome even after a prolonged duration of MCS after TBI. A large proportion of the patients was functionally independent in basic daily activities, although all experienced residual impairments and disabilities. The low correlation coefficients between duration of MCS and the outcome measures suggest that prognostic statements based on length of time a person is in the MCS cannot be made with confidence.
