The influence of intensive care treatment in infancy on cortisol levels in childhood and adolescence. Early Hum Dev 2023; 184:105823. [PMID: 37478692 DOI: 10.1016/j.earlhumdev.2023.105823] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 07/09/2023] [Accepted: 07/09/2023] [Indexed: 07/23/2023]
Abstract
BACKGROUND Infants admitted to the intensive care unit experience numerous early-life stressors, which may have long-term effects on hypothalamic-pituitary-adrenal axis functioning. AIMS To determine the effects of intensive care treatment and related exposure to stress, pain, and opioids in infancy on cortisol levels in childhood and adolescence. STUDY DESIGN Cross-sectional study. SUBJECTS Children and adolescents aged 8 to 18 years with a history of intensive care treatment in infancy and healthy controls. The intensive care treatment cohort consisted of four subgroups with varying levels of exposure to stress, pain, and opioids in infancy. They received either mechanical ventilation, extracorporeal membrane oxygenation, major surgery, or excochleation of a giant congenital melanocytic nevus. OUTCOME MEASURES Between-group differences in stress reactivity to a study visit consisting of pain threshold testing and an MRI examination and diurnal cortisol levels, as measured in saliva. RESULTS After adjustment for age, sex, and gestational age, the diurnal cortisol output (AUCg) in the overall intensive care group (N = 76) was 18 % (approximately 1000 nmol/L) (95 % CI [-31 %, -3 %], P = 0.022) lower than that in the control group (N = 67). Cortisol awakening response, diurnal decline, and stress reactivity neither differed significantly between the overall intensive care group and control group, nor between the intensive care subgroups and control group. CONCLUSION Children and adolescents with a history of intensive care treatment in infancy have similar cortisol profiles to those of healthy controls, except for an 18 % lower diurnal cortisol output. The clinical relevance of this reduction is yet to be determined.

Abstract
OBJECTIVES Our objectives were to quantify pain experienced by young children undergoing facial laceration repair and identify factors associated with low procedural pain scores. METHODS We conducted a prospective cohort study of children's distress among a convenience sample of children aged 1 to 5 years undergoing facial or scalp laceration repair in 2 pediatric emergency departments. We reviewed video recordings and documented pain scores at 15-second intervals using the Face, Leg, Activity, Cry, Consolability-Revised (FLACC-r) scale. We dichotomized FLACC-r into low/high scores (≤3 and >3) to evaluate practice variables. RESULTS We included 11,474 FLACC-r observations from 258 procedures in the analysis. Two-thirds of 3- to 5-year-olds completed their laceration repair without the use of restraint, sedation, or anxiolytics. Mean distress scores were low (≤2.5 out of 10) across all procedure phases for 2- to 5-year-old patients. One-year-old patients experienced significantly more distress than their older counterparts (mean ≤4.2 out of 10). Odds of having low FLACC scores (≤3) were greater for patients with an expert clinician (adjusted odds ratio [aOR]: 1.72; 95% confidence interval [CI], 1.05-2.84). Wound infiltration (aOR, 0.35; 95% CI, 0.13-0.93), patient observation of a needle (aOR, 0.21; 95% CI, 0.14-0.33), and restraint (aOR, 0.04; 95% CI, 0.02-0.06) were negatively associated with low FLACC score. CONCLUSION The majority of 3- to 5-year-old patients were able to undergo facial laceration repair without restraint, sedation, or anxiolytics and with low mean distress scores. Our findings suggest that children's risk of experiencing moderate and severe distress during facial and scalp laceration repair may be reduced by prioritizing wound closure by expert-level clinicians, ensuring effective lidocaine-epinephrine-tetracaine application, avoiding restraint, and concealing needles from patient view.

Abstract
BACKGROUND Contaminated blood cultures pose a significant burden. We sought to determine the impact of contaminated peripheral blood cultures on patients, families, and the health care system. METHODS In this retrospective case-control study from January 1, 2014, to December 31, 2017, we compared the hospital course, return visits and/or admissions, charges, and length of stay of patients with contaminated peripheral blood cultures (case patients) with those of patients with negative cultures (controls). Patients were categorized into those evaluated and discharged from the emergency department (ED) (ED patients) and those who were hospitalized (inpatients). RESULTS A total of 104 ED case patients were matched with 208 ED control patients. A total of 343 case inpatients were matched with 686 inpatient controls. There was no significant difference between case and control patient demographics, ED, or hospital course at presentation. Fifty-five percent of discharged ED patients returned to the hospital for evaluation and/or admission versus 4% of controls. There was a significant (P < .0001) increase in repeat blood cultures (43% vs 1%), consultations obtained (21% vs 2%), cerebrospinal fluid studies (10% vs 0%), and antibiotic administration (27% vs 1%) in ED patients compared with controls. Each ED patient requiring revisit to the hospital incurred, on average, $4660 in additional charges. There was a significant (P < .04) increase in repeat blood cultures (57% vs 7%), consultations obtained (35% vs 28%), broadening of antibiotic coverage (18% vs 11%), median length of stay (75 vs 64 hours), and median laboratory charges ($3723 vs $3296) in case inpatients compared with controls. CONCLUSIONS Contaminated blood cultures result in increased readmissions, testing and/or procedures, length of stay, and hospital charges in children.

Abstract
Regional anesthesia provides effective anesthesia and pain relief in infants with age-specific data attesting to safety and efficacy. Regional anesthesia decreases exposure to opioids and general anesthetic agents and associated adverse drug effects, suppresses the stress response, and provides better hemodynamic stability compared to general anesthesia. Regional anesthesia can prevent long-term behavioral responses to pain. As a result, the overall number and variety of nerve blocks being used in infants is increasing. While neuraxial blocks are the most common blocks performed in infants, the introduction of ultrasound imaging and a better safety profile has advanced the use of peripheral nerve blocks. Infant-specific pharmacokinetic and pharmacodynamic data of local anesthetic medications are reviewed including risk factors for the accumulation of high serum levels of unbound, pharmacologically active drug. Bupivacaine accumulates with continuous infusion and 2-chloroprocaine can be used as an alternative. Local anesthetic systemic toxicity has the highest incidence in infants less than 6 months of age and is associated with bolus dosing and penile nerve blocks. Local anesthetic toxicity is treated by securing the airway, suppression of seizure activity and implementation of cardiopulmonary resuscitation. Administration of intralipid (intravenous lipid emulsion) is initiated at the first sign of toxicity. A high level of expertise in regional anesthesia is needed when treating infants due to their unique development.

Abstract
BACKGROUND Despite being a priority population for HIV prevention and harm reduction programs, the sexual and reproductive health (SRH) needs of women who inject drugs are being overlooked. Furthermore, models for providing integrated SRH, HIV, and harm reduction services for women who inject drugs are rare. This article reports the development of community-based outreach services that integrated family planning and other SRH interventions with HIV and harm reduction services for this population in coastal Kenya. METHODS Using mixed-methods implementation research, a qualitative baseline needs assessment was conducted with women who inject drugs and harm reduction stakeholders using a combination of in-depth interviews and focus group discussions. The qualitative data from participants was subjected to thematic analysis using Nvivo. Based on the baseline needs assessment, integration of SRH into existing HIV and harm reduction services was implemented. After two years of implementation, an evaluation of the program was conducted using a combination of qualitative interviews and review of quantitative service delivery records and other program documents. The process, impacts, and challenges of integrating SRH into a community-based HIV prevention and harm reduction program were identified. RESULTS This article highlights: 1) low baseline utilization of family planning services among women who inject drugs, 2) improved utilization and high acceptability of outreach-based provision of SRH services including contraception among this population, 3) importance of training, capacity strengthening, technical support and financial resourcing of community-based organizations to integrate SRH into HIV prevention and harm reduction services, and 4) the value of beneficiary involvement, advocacy, and collaboration with other partners in the planning, designing and implementing of SRH interventions for women who inject drugs. CONCLUSIONS Women who inject drugs in this study had low utilization of family planning and other SRH services, which can be improved through the integration of contraceptive and other SRH interventions into existing outreach-based HIV prevention and harm reduction programs. This integration is acceptable to women who inject drugs, and is programmatically feasible. For successful integration, a rights-based beneficiary involvement, coupled with sustainable technical and financial capacity strengthening at the community level is essential.

Repeated touch and needle-prick stimulation in the neonatal period increases the baseline mechanical sensitivity and postinjury hypersensitivity of adult spinal sensory neurons. Pain 2019.

Abstract
Neonatal abnormal noxious and tactile stimulations facilitate the activity of spinal neurons, which leads to an altered somatosensory and pain phenotype in adulthood. Noxious stimulation at critical stages of development has long-term consequences on somatosensory processing in later life, but it is not known whether this developmental plasticity is restricted to nociceptive pathways. Here, we investigate the effect of repeated neonatal noxious or innocuous hind paw stimulation on adult spinal dorsal horn cutaneous mechanical sensitivity. Neonatal Sprague-Dawley rats of both sexes received 4 unilateral left hind paw needle pricks (NPs, n = 13) or 4 tactile (cotton swab touch) stimuli, per day (TC, n = 11) for the first 7 days of life. Control pups were left undisturbed (n = 17). When adult (6-8 weeks), lumbar wide-dynamic-range neuron activity in laminae III-V was recorded using in vivo extracellular single-unit electrophysiology. Spike activity evoked by cutaneous dynamic tactile (brush), pinch and punctate (von Frey hair) stimulation, and plantar receptive field areas were recorded, at baseline and 2 and 5 days after left plantar hind paw incision. Baseline brush receptive fields, von Frey hair, and pinch sensitivity were significantly enhanced in adult NP and TC animals compared with undisturbed controls, although effects were greatest in NP rats. After incision, injury sensitivity of adult wide-dynamic-range neurons to both noxious and dynamic tactile hypersensitivity was significantly greater in NP animals compared with TC and undisturbed controls. We conclude that both repeated touch and needle-prick stimulation in the neonatal period can alter adult spinal sensory neuron sensitivity to both innocuous and noxious mechanical stimulation. Thus, spinal sensory circuits underlying touch and pain processing are shaped by a range of early-life somatosensory experiences.

Abstract
Postnatal antiretroviral (ARV) prophylaxis for infants born to women with HIV is a critical component of perinatal HIV transmission prevention. However, variability in prophylaxis regimens remains and consistency with guidelines has not been evaluated in the United States. We evaluated trends over time in prophylaxis regimens among 6386 HIV-exposed uninfected (HEU) infants using pooled data spanning two decades from three US-based cohorts: the Women and Infants Transmission Study (WITS, 1990-2007), Pediatric AIDS Clinical Trials Group (PACTG) 219C (1993-2007), and the PHACS Surveillance Monitoring of ART Toxicities (SMARTT) study (2007-2015). We also identified maternal and infant risk factors for use of combination prophylaxis regimens (≥2 ARVs) and examined consistency with US perinatal guidelines. We found that receipt of combination prophylaxis between 1996 and 2015 ranged from 2% to 15%, with a consistent median duration of 6 weeks. Infants whose mothers had lower CD4 T-cell counts, higher viral load (VL), no antepartum ARVs, age <20 years at delivery, and Cesarean delivery had significantly higher rates of combination prophylaxis, while infants born 2006-2010 (vs. 2011-2015), who were Hispanic or with lower maternal education levels, had significantly lower rates. Predictors for combination prophylaxis varied over time, with the strongest associations of maternal VL in later birth cohorts. While use of combination prophylaxis increased over time, only 50% of high-risk infants received such regimens in 2011-2015. In conclusion, HEU infants at higher risk of HIV acquisition are more likely to receive combination neonatal prophylaxis, consistent with US guidelines. However, substantial variability remains, and infants at higher risk often fail to receive combination prophylaxis.

Abstract
INTRODUCTION Children born very preterm display altered pain thresholds. Little is known about the neonatal clinical and psychosocial factors associated with their later pain perception. OBJECTIVE We aimed to examine whether the number of neonatal invasive procedures, adjusted for other clinical and psychosocial factors, was associated with self-ratings of pain during a blood collection procedure at school age in children born very preterm. MATERIALS AND METHODS 56 children born very preterm (24 to 32 weeks gestational age), followed longitudinally from birth, and free of major neurodevelopmental impairments underwent a blood collection by venipuncture at age 7.5 years. The children's pain was self-reported using the Coloured Analog Scale and the Facial Affective Scale. Parents completed the Child Behavior Checklist and the State-Trait Anxiety Inventory. Pain exposure (the number of invasive procedures) and clinical factors from birth to term-equivalent age were obtained prospectively. Multiple linear regression was used to predict children's pain self-ratings from neonatal pain exposure after adjusting for neonatal clinical and concurrent psychosocial factors. RESULTS A greater number of neonatal invasive procedures and higher parent trait-anxiety were associated with higher pain intensity ratings during venipuncture at age 7.5 years. Fewer surgeries and lower concurrent child externalizing behaviors were associated with a higher pain intensity. CONCLUSIONS In very preterm children, exposure to neonatal pain was related to altered pain self-ratings at school age, independent of other neonatal factors. Neonatal surgeries and concurrent psychosocial factors were also associated with pain ratings.

Abstract
UNLABELLED An ideal taxonomy of chronic pain would be applicable to people of all ages. Developmental sciences focus on lifespan developmental approaches, and view the trajectory of processes in the life course from birth to death. In this article we provide a review of lifespan developmental models, describe normal developmental processes that affect pain processing, and identify deviations from those processes that lead to stable individual differences of clinical interest, specifically the development of chronic pain syndromes. The goals of this review were 1) to unify what are currently separate purviews of "pediatric pain," "adult pain," and "geriatric pain," and 2) to generate models so that specific elements of the chronic pain taxonomy might include important developmental considerations. PERSPECTIVE A lifespan developmental model is applied to the forthcoming Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks-American Pain Society Pain Taxonomy to ascertain the degree to which general "adult" descriptions apply to pediatric and geriatric populations, or if age- or development-related considerations need to be invoked.

Abstract
To provide an updated synthesis of the current state of the evidence for the effectiveness of breast-feeding and expressed breast milk feeding in reducing procedural pain in preterm and full-term born infants. A systematic search of key electronic databases (PubMed, CINAHL, EMBASE) was completed. Of the 1032 abstracts screened, 21 were found eligible for inclusion. Fifteen studies reported on the use of breast-feeding or expressed breast milk in full-term infants and 6 reported on preterm infants. Direct breast-feeding was more effective than maternal holding, maternal skin-to-skin contact, topical anesthetics, and music therapy, and was as or more effective than sweet tasting solutions in full-term infants. Expressed breast milk was not consistently found to reduce pain response in full-term or preterm infants. Studies generally had moderate to high risk of bias. There is sufficient evidence to recommend direct breast-feeding for procedural pain management in full-term infants. Based on current evidence, expressed breast milk alone should not be considered an adequate intervention.

Abstract
This article reviews current understanding of the management of mother-to-child transmission of HIV-1 infection in the context of developed-country settings. The advent of highly active antiretroviral therapy has facilitated the virtual elimination of mother-to-child transmission of HIV infection in developed countries, reducing transmission rates to approximately 1–2%. This review describes the epidemiology of HIV infection among women of child-bearing age and the risk factors, timing and mechanisms of mother-to-child transmission, followed by a discussion of the identification of pregnant HIV-infected women and their therapeutic and obstetric management.

Abstract
BACKGROUND Pain from skin penetrating procedures (procedural pain) during infancy in the neonatal intensive care unit (NICU) may result in changes of nociceptive sensitivity in later life. This supports the need for pain management during such vulnerable periods in life. This study, therefore, analyses the short- and long-term consequences of neonatal paracetamol (acetaminophen) treatment on pain behaviour in an experimental rat model of neonatal procedural pain. METHODS A repetitive needle-prick model was used, in which neonatal rats received four needle pricks into the left hind paw per day from postnatal day 0 to day 7 (P0-P7). Paracetamol (50 mg/kg/day s.c.) was administered daily (P0-P7), and sensitivity to mechanical stimuli was compared with a needle-prick/saline-treated group and to a tactile control group. At 8 weeks of age, all animals underwent an ipsilateral paw-incision, modelling postoperative pain, and the duration of hypersensitivity was assessed. RESULTS Neonatal paracetamol administration had no effect upon short-term mechanical hypersensitivity during the first postnatal week or upon long-term baseline sensitivity from 3 to 8 weeks. However, neonatal paracetamol administration significantly reduced the postoperative mechanical hypersensitivity in young adults, caused by repetitive needle pricking. CONCLUSION Paracetamol administration during neonatal procedural pain does not alter short-term or long-term effects on mechanical sensitivity, but does reduce the duration of increased postoperative mechanical hypersensitivity in a clinically relevant neonatal procedural pain model. WHAT DOES THIS STUDY ADD Paracetamol can be used safely in neonatal rats. Neonatal paracetamol treatment had no effect upon short-term mechanical hypersensitivity during the first postnatal week, nor upon long-term baseline sensitivity from 3 to 8 weeks. Paracetamol treatment during the first postnatal week significantly reduced the postoperative mechanical hypersensitivity in young adult rats.

Abstract
Neonatal abstinence syndrome (NAS) is reaching epidemic proportions related to perinatal use of opioids. There are many approaches to assess and manage NAS, including one we have outlined. A standardized approach is likely to reduce length of stay and variability in practice. Circumcision is a frequent, painful procedure performed in the neonatal period. The rationale for providing analgesia is presented as well as a review of methods. Pharmacogenomics and pharmacogenetics have expanded our understanding of diseases and their drug therapy. Some applications of pharmacogenomics to the neonatal period are presented, along with pediatric challenges of developmental expression of drug-metabolizing enzymes.

Abstract
Background: Several measurement tools have been used for assessment of postoperative pain in pediatric patients. Self-report methods have limitations in younger children and parent, nurse or physician assessment can be used as a surrogate measure. These tools should be tested in different cultures as pain can be influenced by sociocultural factors. The objective was to assess the inter-rater agreement on four different behavioral pain assessment scales in our local population. Materials and Methods: This prospective, descriptive, observational study was conducted in Pakistan. American Society of Anesthesiologists I and II children, 3-7 years of age, undergoing elective surgery were enrolled. Four pain assessment scales were used, Children's Hospital of Eastern Ontario Pain Scale (CHEOPS), Toddler Preschool Postoperative Pain Scale (TPPPS), objective pain scale (OPS), and Face, Legs, Activity, Cry, Consolability (FLACC). After 15 and 60 min of arrival in the postanesthesia care unit (PACU), each child evaluated his/her postoperative pain by self-reporting and was also independently assessed by the PACU nurse, PACU anesthetist and the parent. The sensitivity and specificity of the responses of the four pain assessment scales were compared to the response of the child. Results: At 15 min, sensitivity and specificity were >60% for doctors and nurses on FLACC, OPS, and CHEOPS scales and for FLACC and CHEOPS scale for the parents. Parents showed poor agreement on OPS and TPPS. At 60 min, sensitivity was poor on the OPS scale by all three observers. Nurses showed a lower specificity on FLACC tool. Parents had poor specificity on CHEOPS and rate of false negatives was high with TPPS. Conclusions: We recommend the use of FLACC scale for assessment by parents, nurses, and doctors in Pakistani children aged between 3 and 7.

Abstract
BACKGROUND A high delivery maternal plasma HIV-1 RNA level (viral load [VL]) is a risk factor for mother-to-child transmission and poor maternal health. OBJECTIVE To identify factors associated with detectable VL at delivery despite initiation of highly active antiretroviral therapy (HAART) during pregnancy. DESIGN Multicenter observational study. (ClinicalTrial.gov: NCT00028145). SETTING 67 U.S. AIDS clinical research sites. PATIENTS Pregnant women with HIV who initiated HAART during pregnancy. MEASUREMENTS Descriptive summaries and associations among sociodemographic, HIV disease, and treatment characteristics; pregnancy-related risk factors; and detectable VL (>400 copies/mL) at delivery. RESULTS Between 2002 and 2011, 671 women met inclusion criteria and 13.1% had detectable VL at delivery. Factors associated with detectable VL included multiparity (16.4% vs. 8.0% nulliparity; P = 0.002), black ethnicity (17.6% vs. 6.6% Hispanic and 6.6% white; P < 0.001), 11th grade education or less (17.6% vs. 12.1% had a high school diploma; P = 0.013), initiation of HAART in the third trimester (23.9% vs. 12.3% and 8.6% in the second and trimesters, respectively; P = 0.003), having an HIV diagnosis before the current pregnancy (16.1% vs. 11.0% during the current pregnancy; P = 0.051), and having the first prenatal visit in the third trimester (33.3% vs. 14.3% and 10.5% in the second and third trimesters, respectively; P = 0.002). Women who had treatment interruptions or reported poor medication adherence were more likely to have detectable VL at delivery. LIMITATION Data on many covariates were incomplete because women entered the study at varying times during pregnancy. CONCLUSION A total of 13.1% of women who initiated HAART during pregnancy had detectable VL at delivery. The timing of HAART initiation and prenatal care, along with medication adherence during pregnancy, were associated with detectable VL at delivery. Social factors, including ethnicity and education, may help identify women who could benefit from focused efforts to promote early HAART initiation and adherence.

Abstract
The false assumption that neonates are less sensitive to pain than adults led to a long delay in the introduction of a reasonable pain therapy for children. Even if the basic principles of the development, transmission and perception of pain in premature infants and neonates are not completely understood, the results of studies have clearly shown that pain can be perceived from 22 weeks of gestation onwards. This knowledge results in the necessity to also administer an adequate pain therapy to premature and newly born infants. However, for the use of pharmaceuticals in neonates and infants the pharmacodynamic and pharmacokinetic characteristics must also be considered. The immaturity of the organs liver and kidneys limits the metabolism and also excretion processes. The different physical proportions also modify the dosing of pharmaceuticals. Children in the first year of life differ substantially from adults in physiology, pharmacodynamics and pharmacokinetics. The care of neonates and infants requires specialist knowledge which is described in this article.

Abstract
Nociceptive pathways are functional following birth. In addition to physiological and behavioral responses, neurophysiological measures and neuroimaging evaluate nociceptive pathway function and quantify responses to noxious stimuli in preterm and term neonates. Intensive care and surgery can expose neonates to painful stimuli when the developing nervous system is sensitive to changing input, resulting in persistent impacts into later childhood. Early pain experience has been correlated with increased sensitivity to subsequent painful stimuli, impaired neurodevelopmental outcomes, and structural changes in brain development. Parallel preclinical studies have elucidated underlying mechanisms and evaluate preventive strategies to inform future clinical trials.

Abstract
Effects of early life psychosocial adversity have received a great deal of attention, such as maternal separation in experimental animal models and abuse/neglect in young humans. More recently, long-term effects of the physical stress of repetitive procedural pain have begun to be addressed in infants hospitalized in neonatal intensive care. Preterm infants are more sensitive to pain and stress, which cannot be distinguished in neonates. The focus of this review is clinical studies of long-term effects of repeated procedural pain-related stress in the neonatal intensive care unit (NICU) in relation to brain development, neurodevelopment, programming of stress systems, and later pain sensitivity in infants born very preterm (24-32 weeks' gestational age). Neonatal pain exposure has been quantified as the number of invasive and/or skin-breaking procedures during hospitalization in the NICU. Emerging studies provide convincing clinical evidence for an adverse impact of neonatal pain/stress in infants at a time of physiological immaturity, rapidly developing brain microstructure and networks, as well as programming of the hypothalamic-pituitary-adrenal axis. Currently it appears that early pain/stress may influence the developing brain and thereby neurodevelopment and stress-sensitive behaviors, particularly in the most immature neonates. However, there is no evidence for greater prevalence of pain syndromes compared to children and adults born healthy at full term. In addressing associations between pain/stress and outcomes, careful consideration of confounding clinical factors related to prematurity is essential. The need for pain management for humanitarian care is widely advocated. Non-pharmacological interventions to help parents reduce their infant's stress may be brain-protective.

Abstract
OBJECTIVE The objective of this study was to measure the impact of a structured intervention on pain management in a pediatric emergency department (ED). METHODS Data were prospectively collected from children presenting to an urban tertiary care pediatric ED before and after intervention. Data were collected on the rate and timeliness of analgesic administration, the assessment and reassessment of pain, periprocedural anesthesia, and patient satisfaction. The intervention was developed by a multidisciplinary committee composed of physicians, nurses, and child life specialists and was focused on correcting deficiencies identified before intervention data collection. It consisted of a policy defining pain, pain-appropriate analgesia, age-appropriate pain assessment, and adequate preprocedural and periprocedural analgesia. Implementation occurred through provider education, organizational changes, and patient empowerment. RESULTS One hundred two patients were enrolled during the preintervention period, and 109 were enrolled in the postintervention period. The percentage of patients in pain receiving any analgesic increased from 34% to 50%, an increase of 16% (95% confidence interval [CI], 1%-30%). The median time to medication administration decreased from 97 minutes to 57 minutes, a decrease of 40 minutes (95% CI, -84 to 4 minutes). The percentage of children receiving preprocedural analgesia increased from 10% to 62%, an increase of 52% (95% CI, 12%-74%). Reassessment of pain by physicians increased from 6% to 76%, an increase of 70% (95% CI, 59%-78%). CONCLUSIONS A structured intervention, tailored to pain management shortcomings commonly found in the pediatric ED, can lead to improvements in the treatment and prevention of pain in childhood emergencies.

Abstract
BACKGROUND Historically, pain has been poorly managed in the pediatric emergency department (ED) (PED), resulting in measurable psychosocial issues both acute and delayed. OBJECTIVE The aim of the study was to measure the impact of protocolized pain management on patients with painful conditions or undergoing painful procedures in the PED. METHODS We performed an analysis before and after the implementation of the protocol, dubbed the "Comfort Zone." Validated, age-appropriate pain scales were performed. Validation (using Cronbach α, confirmatory factor analysis) was followed by comparison of responses between the pre- and posttests collected (χ(2) and Wilcoxon rank sum tests). Pain scores were collected at triage and at discharge. At triage, patients were asked to report pain levels. At discharge, they were asked to report their current pain and recall the level of pain during their stay. At triage, parents were asked to report about their perception of the child's pain. At discharge, they were asked to report about their perception of the child's current pain and recall the level of pain during the stay and during procedures, if done. RESULTS Five hundred thirty-one patients were enrolled in the preprotocol group; 47% were women with a median age of 5 years (range, 30 days-18 years). Two hundred sixty-three patients were enrolled in the protocol group; 39% were women with a median age of 6 years (range, 30 days-18 years). Patient-recalled pain scores of the ED visit in the protocol group were significantly lower than those of the preprotocol group (Wong-Baker Faces Pain Scale, 5.07-4.01; P < .001); yet parent estimates of pain did not show a significant change at any point. Patient assessment of pain at ED discharge did not show a significant change either (Wong-Baker Faces Pain Scale, 1.99-1.56; P = .09). The Faces scale is not well validated for patients younger than 4, so that group had only parental assessment of pain and, consistent with the larger data set, showed no significant pain scale reduction at any point. CONCLUSION Protocolized pain management reduces patients' memory of pain during PED visits but may not affect parental memory of perceived pain or parent- and patient-reported pain at discharge.

Abstract
Assessing pain intensity in (preverbal) children is more difficult than in adults. Tools to measure pain are being used as primary endpoints [e.g., pain intensity, time to first (rescue) analgesia, total analgesic consumption, adverse effects, and long-term effects] in studies on the effects of analgesic drugs. Here, we review current and promising new endpoints used in pediatric pain assessment studies.

Abstract
Neonates are both capable of experiencing pain and memory formation, albeit implicit memory. During surgical procedures, insufficient ablation of the stress response and possible implicit memory formation of intra-operative events might result in adverse early and long-term outcomes. Neonates deserve the same respect as adult patients. It is thus the responsibility of the anaesthetist to provide sufficient anaesthesia for neonates undergoing surgery. A critical approach in weighing the risks and benefits of exposing a neonate to anaesthesia is prudent, and truly elective surgery should be delayed.

Abstract
Background The burden of mother-to-child transmission of HIV in Uganda is high. The aim of this paper is to describe the experience of the first 7 years of the prevention of mother- to- child transmission of HIV (PMTCT) programme in Mbale Regional Hospital, Eastern Uganda, with particular reference to the lessons learnt in changing from voluntary counselling and testing (VCT) to routine counselling and testing (RCT) for HIV testing in antenatal services. Methods The study was a retrospective analysis of the PMTCT records of Mbale Regional Referral Hospital, Uganda, from May 2002 to April 2009. The data on HIV testing of pregnant women and their male partners was extracted from the reports and registers using a standardized data extraction form, and data was analysed using descriptive statistics. Permission to conduct the study was obtained from School of Medicine, Makerere University College of Health Sciences; Uganda National Council of Science and Technology, and Mbale Hospital. Results A total of 54 429 new antenatal (ANC) attendees and 469 male-partners accessed antenatal services at Mbale Regional Referral Hospital. There was a sustained, significant increase in HIV testing among new ANC attendees from 22% during the VCT period to 88% during the RCT period (p = 0.002), while among male partners, HIV testing increased from 88% to 100% (p = 0.010) However, the overall number of male partners who tested for HIV remained very low despite the change from VCT to RCT approach in HIV testing. Conclusions Routine offer of antenatal HIV testing dramatically increased HIV testing in pregnant women and their partners in Uganda. Our findings call for further strengthening of the policy for routine HIV testing in antenatal clinics. Our study also showed that male partner HIV testing in antenatal clinics is low and this area needs further work through research and innovative interventions in order to improve male partner involvement.

Abstract
OBJECTIVE To describe the various anesthetic techniques used for surgical closure of PDA in premature infants at the Montreal Children's Hospital and assess their impact on postoperative outcome. STUDY DESIGN The charts of all preterms who underwent PDA ligation during a 21-month period were reviewed for preoperative status, intraoperative anesthetic management and postoperative outcome. We determined the associations between independent variables and two postoperative outcome variables: unstable postoperative respiratory course (UPRC) and hypotension. RESULT The mean weight at surgery of the 33 infants was 1.031±0.29 kg. All infants, but one, received intraoperative opioids. Eight patients presented UPRC. Mean fentanyl doses were 5.3±2.6 mcg kg(-1) for patients with UPRC vs 22.6±16.6 mcg kg(-1) for patients without UPRC (P=0.004). Applying the receiver-operator characteristic curve (ROC), 10.5 mcg kg(-1) of fentanyl was established as the dose that discriminated and identified patients who experienced UPRC. The postnatal and postmenstrual age of the patient, birthweight, current weight, ventilator settings preoperatively, previous courses of indomethacin, sex and preoperative creatinine, were not correlated with the dose of fentanyl equivalent used. Logistic regression did not show a relationship between any of the previously mentioned factors and receiving a fentanyl equivalent of >10.5 mcg kg(-1). The only factor associated with the total fentanyl equivalent dose (as a continuous variable) or receiving <10.5 mcg kg(-1) (as a dichotomous variable) was the identity of the anesthetist involved, P<0.001. CONCLUSION We conclude that the use of at least 10.5 mcg kg(-1) of fentanyl equivalent as a component of the anesthetic regimen for surgical closure of a PDA in premature infants, avoids an unstable postoperative respiratory course.

Abstract
Over the last several decades, the relative contribution of early life events to individual disease susceptibility has been explored extensively. Only fairly recently, however, has it become evident that abnormal or excessive nociceptive activity experienced during the perinatal period may permanently alter the normal development of the CNS and influence future responses to somatosensory input. Given the significant rise in the number of premature infants receiving high-technology intensive care over the last 20 years, ex-preterm neonates may be exceedingly vulnerable to the long-term effects of repeated invasive interventions. The present review summarizes available clinical and laboratory findings on the lasting impact of exposure to noxious stimulation during early development, with a focus on the structural and functional alterations in nociceptive circuits, and its sexually dimorphic impact.

Abstract
Despite mounting evidence on the importance of pain management in preterm infants, clinical use of analgesics in this population is limited. Our previous studies have shown that neonatal inflammation results in long-term alterations in adult somatosensory thresholds, characterized by decreased baseline nociceptive sensitivity, and enhanced hyperalgesia after a subsequent inflammatory insult. The present studies were conducted to determine whether preemptive morphine attenuates these negative consequences. At P0, pups received an injection of morphine sulfate before an intraplantar injection of 1% carrageenan. Control pups received either saline (SAL) followed by intraplantar carrageenan, morphine sulfate followed by intraplantar SAL, or SAL followed by intraplantar SAL. Preemptive morphine significantly attenuated neonatal injury-induced hypoalgesia in adolescence and adulthood. Similarly, morphine pretreated animals displayed significantly less hyperalgesia and recovered faster from a subsequent inflammatory insult compared with controls. Neonatal morphine had no significant effect on morphine analgesia in adulthood. Interestingly, neonatally injured animals that did not receive morphine displayed a significant rightward shift in the morphine dose-response curve in the absence of peripheral inflammation. Together, these results demonstrate that preemptive morphine significantly attenuates the long-term behavioral impact of neonatal inflammatory injury.

Abstract
Increasing evidence has demonstrated that pain from venipuncture and intravenous cannulation is an important source of pediatric pain and has a lasting impact. Ascending sensory neural pain pathways are functioning in preterm and term infants, yet descending inhibitory pathways seem to mature postnatally. Consequently, infants may experience pain from the same stimulus more intensely than older children. In addition, painful perinatal procedures such as heel lancing or circumcision have been found to correlate with stronger negative responses to venipuncture and intramuscular vaccinations weeks to months later. Similarly, older children have reported greater pain during follow-up cancer-related procedures if the pain of the initial procedure was poorly controlled, despite improved analgesia during the subsequent procedures. Fortunately, both pharmacologic and nonpharmacologic techniques have been found to reduce children's acute pain and distress and subsequent negative behaviors during venipuncture and intravenous catheter insertion. This review summarizes the evidence for the importance of managing pediatric procedural pain and methods for reducing venous access pain.

Abstract
Postoperative pain assessment and management in preverbal children and children with cognitive impairment poses major challenges to pediatric anesthesiologists. An accurate diagnosis of extent of pain is the keystone for the successful management of pain. This article reviews the neurobiology of pain at birth, long-term consequences of early pain and different pediatric pain assessment tools used for postoperative assessment in infants, young children, and children with cognitive disabilities.

Preterm births: can neonatal pain alter the development of endogenous gating systems? Eur J Pain 2008; 12:945-51.

Abstract
Prematurity is known to affect the development of various neurophysiological systems, including the maturation of pain and cardiac circuits. The purpose of this study was to see if numerous painful interventions, experienced soon after birth, affect counterirritation-induced analgesia (triggered using the cold pressor test) later in life. A total of 26 children, between the ages of 7 and 11 participated in the study. Children were divided into three groups, according to their birth status (i.e., term-born, born preterm and exposed to numerous painful interventions, or born preterm and exposed to few painful interventions). Primary outcome measures were heat pain thresholds, heat sensitivity scores, and cardiac reactivity. Results showed that preterm children and term-born children had comparable pain thresholds. Exposure to conditioning cold stimulation significantly increased heart rate and significantly decreased the thermal pain sensitivity of term-born children. These physiological reactions were also observed among preterm children who were only exposed to a few painful interventions at birth. Changes in heart rate and pain sensitivity in response to conditioning cold stimulation were not observed in preterm children that had been exposed to numerous painful procedures during the neonatal period. These results suggest that early pain does not lead to enhanced pain sensitivity when premature babies become children, but that their endogenous pain modulatory mechanisms are not as well developed as those of children not exposed to noxious insult at birth. Greater frequency of painful procedures also dampened the rise in heart rate normally observed when experimental pain is experienced.

Abstract
OBJECTIVE To determine if women with undocumented HIV status in late pregnancy or at labor and delivery who are rapidly tested and identified as HIV infected have high-risk behaviors and psychosocial obstacles hindering postpartum follow-up. METHODS Consenting participants (women with undocumented HIV status and > or =24 weeks gestational age (GA) and imminent delivery or > or =34 weeks GA) in 6 cities were rapidly tested and interviewed. HIV-positive women were offered follow-up. RESULTS From 2001-2005, 54 HIV-infected women were identified: median age 26 years; 91% African American; 11 (20%) lost custody of their infants; 30 (56%) knew they or their partner were HIV-infected, but had no antenatal HIV care; 25 met criteria for starting antiretroviral therapy. Comparison between 48 HIV-infected and 130 HIV-negative women, tested and interviewed at the same hospitals, showed HIV-infected women more likely to be African American (P < .01) and report no prenatal care (P < .001), use street drugs (P < .01), have unstable residency (P < .05), not live with the father of their infant (P < .001), and have children in foster care (P < .01). Sixteen women (30%) and 17 (31%) infants did not remain in follow-up study due to relocation, child protective custody, and psychosocial issues including frequent substance use. CONCLUSION Over half of HIV-infected women knew they or their partner were infected with HIV, but did not initially disclose their status. Increased support services and substance abuse treatment are critical to facilitate better continuity of care for these socially marginalized women.

Abstract
BACKGROUND In contrast to the well-described 10% risk of chronic pain affecting daily activities after adult groin hernia repair, chronic pain after childhood groin hernia repair has never been investigated. Studies of other childhood surgery before the age of 3 months suggest a risk of increased pain responsiveness later in life, but its potential relationship to chronic pain in adult life is unknown. METHODS This was a nationwide detailed questionnaire study of chronic groin pain in adults having surgery for a groin hernia repair before the age of 5 years (n = 1075). RESULTS The response rate was 63.3%. In the 651 patients available for analysis, pain from the operated groin was reported by 88 (13.5%) patients whereof 13 (2.0%) patients reported frequent and moderate or severe pain. Pain occurred primarily when exercising sports or other leisure activities. Patients operated on before the age of 3 months (n = 122) did not report groin pain more often or with higher intensity than other patients did. CONCLUSIONS Groin pain in adult patients operated on for a groin hernia in childhood is uncommon and usually mild and occurs in relation to physical activity. Operation before the age of 3 months does not increase the risk of chronic pain.

Abstract
The prevention of pain in neonates should be the goal of all caregivers, because repeated painful exposures have the potential for deleterious consequences. Neonates at greatest risk of neurodevelopmental impairment as a result of preterm birth (ie, the smallest and sickest) are also those most likely to be exposed to the greatest number of painful stimuli in the NICU. Although there are major gaps in our knowledge regarding the most effective way to prevent and relieve pain in neonates, proven and safe therapies are currently underused for routine minor yet painful procedures. Every health care facility caring for neonates should implement an effective pain-prevention program, which includes strategies for routinely assessing pain, minimizing the number of painful procedures performed, effectively using pharmacologic and nonpharmacologic therapies for the prevention of pain associated with routine minor procedures, and eliminating pain associated with surgery and other major procedures.

Abstract
HIV counseling and testing services are critical for individuals to access HIV prevention and treatment. Unfortunately, the standard HIV testing algorithm is complex and includes the use of a sensitive enzyme immunoassay (EIA), followed by a Western blot if the EIA is positive. This process can take 1 week or longer. Therefore, innovative approaches that incorporate simpler diagnostic algorithms are needed to reach the large number of individuals who are not aware that they are HIV-infected. Currently available rapid HIV tests have demonstrated sensitivities and specificities comparable to those of standard HIV testing without the requirements of sophisticated laboratory resources or highly trained personnel. These rapid HIV tests are increasingly being used in various clinical scenarios to decrease the number of missed opportunities for detection of HIV-infection. Their use is particularly applicable in specific clinical and nonclinical settings; public health settings; labor and delivery wards; in the management of occupational exposures; and in resource-constrained settings. The overarching goals of achieving wide implementation of rapid HIV tests are to increase the number of individuals who are aware of their serostatus, to improve entry of persons with HIV into prevention and care services, and to prevent further HIV transmission.

Abstract
Using a semi-structured survey and convenience sample of pregnant/recently delivered Hispanic (n = 453) and non-Hispanic (n = 904) women in four California counties, this study compared rates of timely prenatal care (PNC) initiation, HIV test counseling, test offering, and test acceptance in PNC between Hispanic and non-Hispanic women. Hispanic women were less likely to report timely PNC initiation (69.3% vs. 80.4%, p < .0001), receiving test offer (69.5% vs. 76.7%, p = .002), and ever having been tested (77.3% vs. 87.9%, p < .0001) than non-Hispanic women. Hispanic women were more likely to report not knowing where to go (p = .04) and having no insurance (p < .001), transportation (p = .001), and child care (p = .007) as reasons for late PNC start. Both Hispanic and non-Hispanic women most commonly accepted a test offer for their health/health of their baby; Hispanic women were more likely to accept based on doctor/nurse recommendation (80.1% vs. 62.7%, p < .001). A quarter of Hispanic and non-Hispanic women reported they didn't feel they had a choice or that test was done automatically. Efforts to improve perinatal HIV prevention opportunities for all women in California are required. Furthermore, Hispanic women may have disparities in receipt of prenatal care and HIV test offer that need additional attention.

Abstract
OBJECTIVE This work aimed at performing a retrospective and comparative investigation of pharmacological therapeutic approach for pain and inflammation control for cleft lip and/or palate repair. STUDY DESIGN Medical charts from 2000 patients who underwent surgical procedures at the Hospital for Rehabilitation of Craniofacial Anomalies, University of São Paulo (HRAC-USP), Brazil, were assessed to obtain information regarding type of cleft, surgical procedure, and analgesic and anti-inflammatory drugs prescribed. The first 1000 consecutive surgeries performed in 1992 and 2002 were assessed. RESULTS Different analgesic and anti-inflammatory agents-nonsteroidal anti-inflammatory drugs (NSAIDS), steroids, and opioids-were given to patients perioperatively and postoperatively. NSAIDS were given to almost all patients (97.03% in 1992 and 99.88% in 2002, P > .05). Steroid administration increased in 2002 (8.66% versus 17.71%, P < .05). Opioids were administered only in 2002 (50.31%, P < .05). CONCLUSION NSAIDS, steroids, and opioids were used for pain and inflammation control in cleft lip and palate repair at HRAC-USP. A change in the pattern of analgesic and anti-inflammatory drug use was observed when comparing 1992 and 2002. More potent compounds, such as opioids, were used in 2002 in a significant percentage of all the surgical procedures.

Abstract
Newborn infants are not small adults. The pharmacokinetics and dynamics of analgesic drugs are immature at birth. Volumes of distribution, drug clearances, side-effects and drug efficacy all differ in newborns as compared to adults. Interestingly, these parameters develop before birth and during the postnatal period, reaching adult values after a period of months or years. This means that clinicians should anticipate on pharmacokinetic/pharmacodynamic (PK/PD) changes in newborns with increasing post-conceptual age. The ability to perceive pain might also be immature at birth. Lower pain thresholds due to the absence of inhibitory descending spinothalamic fibers and a not yet fully developed cortical pain memory system are points of interest for our understanding of differences in pain perception in the newborn infant. Although this is a relatively unexplored area of research in humans, we will discuss the maturation and development of neonatal pain experience and perception in this paper.

Abstract
The low tactile threshold in preterm infants when they are in the neonatal intensive care unit (NICU), while their physiological systems are unstable and immature, potentially renders them more vulnerable to the effects of repeated invasive procedures. There is a small but growing literature on pain and tactile responsivity following procedural pain in the NICU, or early surgery. Long-term effects of repeated pain in the neonatal period on neurodevelopment await further research. However, there are multiple sources of stress in the NICU, which contribute to inducing high overall 'allostatic load', therefore determining specific effects of neonatal pain in human infants is challenging.

Abstract
The Centers for Disease Control and Prevention (CDC) recently recommended that HIV screening should become routine for all adults in the United States. Implicit in the CDC proposal is the notion that pre-test counseling would be more limited than at present, and that written informed consent to screening would no longer be required. If widely implemented, routine testing would mark a tremendous shift in the US HIV screening strategy. There are a number of considerations used to determine what screening tests should be routine, and HIV fits the bill in almost every regard. Yet the stigma associated with HIV infection remains, making the CDC's recommendation highly controversial. Will minimizing requirements for pre-test counseling and special written informed consent lead to unexpected or unwanted HIV testing, or do these stringent counseling and consent requirements needlessly scare people away? Will widespread and routine testing be associated with declining stigmatization, or will it drive some patients away from seeking desperately needed health care? These are high stakes questions, and we're about to find out the answers.

Abstract
Iatrogenic pain is commonplace in newborn infants yet we know very little about its long-term effects. This article reviews the evidence for and against the suggestion that painful procedures experienced in the perinatal period influence subsequent pain responses in infancy or in childhood. The evidence suggests that early experiences with pain are associated with altered pain responses later in infancy. The direction of the altered response depends, in part, on the infant's developmental stage (full-term vs preterm), and his or her cumulative experience with pain. Preterm infants that are hospitalized as neonates and subjected to painful procedures appear to have a dampened response to painful procedures later in infancy. Full-term neonates exposed to extreme stress during delivery, or to a surgical procedure, react to later noxious procedures with heightened behavioral responsiveness. Studies in which analgesic agents (local anesthetics or opioids) have been administered prior to noxious procedures demonstrate less procedural pain and a reduction in the magnitude of long-term changes in pain behaviors. The precise determinants of these changes, their extent, and their permanence are not known but they appear to involve noxious stimulus-induced peripheral and central sensitization, as well as classical conditioning.
