Eur J Pediatr 2024; 183:2819-2830. [PMID: 38581462 PMCID: PMC11192662 DOI: 10.1007/s00431-024-05516-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Revised: 03/07/2024] [Accepted: 03/08/2024] [Indexed: 04/08/2024]
Abstract
Measurement of transcutaneous bilirubin (TcB) is a non-invasive, widely used technique to estimate serum bilirubin (SB). However, its reliability in multiethnic populations during and after phototherapy is still controversial even in covered skin. The aim of this study was to determine the reliability of TcB in covered (cTcB) and exposed (eTcB) skin during and after phototherapy in a multiethnic population of term and preterm neonates according to Neomar's neonatal skin color scale. Prospective, observational study comparing SB and TcB. We determined SB when clinically indicated and, at the same time, measured cTcB under a photo-opaque patch and eTcB next to it with a jaundice meter (Dräger JM-105TM). All dyads TcB-SB were compared, both globally and according to skin color. We obtained data from 200 newborns (color1: 44, color2: 111, color3: 41, color4: 4) and compared 296 dyads TcB/SB. Correlation between cTcB and SB is strong during (0.74-0.83) and after (0.79-0.88) phototherapy, both globally and by color group. The SB-cTcB bias depends on gestational age during phototherapy and on skin color following phototherapy. The correlation between eTcB and SB during phototherapy is not strong (0.54), but becomes so 12 h after discontinuing phototherapy (0.78). Conclusions: Our study supports the reliability of cTcB to assess SB during and after phototherapy, with differences among skin tones after the treatment. The use of cTcB and Neomar's scale during and mainly after phototherapy may help reduce the number of blood samples required. What is Known: • Controversies exist on the reliability of jaundice meters during and after phototherapy in covered skin. Only a few studies have analyzed their accuracy in multiethnic populations, but none has used a validated neonatal skin color scale. What is New: • We verified correlation between serum and transcutaneous bilirubin in covered skin in a multiethnic population depending on skin color based on our own validated neonatal skin color scale during and after phototherapy.

[PMID: 37729162 PMCID: PMC10545068 DOI: 10.1097/asw.0000000000000043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Accepted: 07/17/2023] [Indexed: 09/22/2023]
Abstract
OBJECTIVE To examine the effectiveness of the ColorMeter DSM III (ColorMeter; Cortex Technology) at grouping individuals by skin tone and measuring erythema/skin discoloration after erythema induction across skin tones. METHODS This pre/post experimental study induced erythema on a convenience sample of 61 healthy adults. Skin tone at baseline was measured using the ColorMeter, Munsell Soil Color Chart 5YR (Munsell), and Pantone SkinTone Guide (Pantone) and compared with the Eumelanin Human Skin Colour Scale (Eumelanin Scale) groupings. Erythema and melanin values on the arm immediately and after recovery time were compared with baseline values. Melanin was measured at five body regions on the face and arm. RESULTS Participants were predominantly women (64% [n = 39] women, 36% [n = 22] men) and young (mean, 28.8 ± 14.3 years); 5% (n = 3) were Hispanic, 26% (n = 16) Asian, 29% (n = 18) Black, 38% (n = 23) White, and 7% (n = 4) identified with more than one race. ColorMeter lightness (L*) and melanin measures were strongly correlated with both Munsell and Pantone values. Munsell skin tone groups were not aligned with Eumelanin Scale groupings. Most participants were in the Eumelanin intermediate-low group, and this changed depending on which body location melanin value was used. The change in erythema from baseline did not differ significantly across skin tone groups at the ulnar head, but on the forearm at the delayed time point, significant differences existed between light and both medium and dark skin tone groups (P = .001; 95% CI, 0.04-0.37). CONCLUSIONS The ColorMeter provides an effective objective measure of skin tone and erythema/discoloration across various skin tones and may improve on current standards for detection. The proposed Eumelanin Scale-Modified provides additional sensitivity for persons with medium skin tones.

PLoS One 2022; 17:e0264694. [PMID: 35239710 PMCID: PMC8893663 DOI: 10.1371/journal.pone.0264694] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2021] [Accepted: 02/15/2022] [Indexed: 11/19/2022] Open
Abstract
Background Neonatal jaundice (NNJ) is a major cause of preventable childhood mortality and long-term impairment especially in countries with significant prevalence of the inherited condition, glucose-6-phosphate dehydrogenase (G6PD) defect. In Ghana, routine screening of pregnant women for G6PD defect is standard care. Prevention of poor health outcomes from NNJ is contingent on population health literacy and early diagnosis. As part of a project to evaluate a screening tool for NNJ, we assessed the knowledge, attitude, and perceptions of Ghanaian mothers on NNJ at baseline. Methods Using a cross-sectional design, mothers attending antenatal and postnatal clinics at 3 selected health facilities in 2 geographical regions of Ghana were interviewed. Data on mothers’ understanding, perceptions, beliefs, and actions towards NNJ were evaluated. Chi-square test was used to determine the association between selected maternal characteristics and knowledge, attitude, and perception to NNJ. Results Of the 504 mothers interviewed, 428(85.4%) had heard about NNJ, 346 (68.7%) said the earliest signs are seen in the eyes, 384(76.2%) knew NNJ may be harmful and 467(92.7%) recommended seeking healthcare for the jaundiced newborn. None of the women knew about G6PD or their G6PD status following antenatal screening. Most did not know the signs/symptoms of severe NNJ. Of the 15 mothers who had had a jaundiced neonate, cost was the most perceived (8 out of 15) barrier to accessing health care. There were significant associations (p-value ≤ 0.05) between maternal age, educational level, and knowledge of NNJ. Conclusion Despite the high level of awareness of NNJ, gaps still exit in the knowledge, attitudes and perceptions of mothers concerning NNJ. Improving education of women about the causes, symptoms/signs, and the role of G6PD in severe NNJ is recommended. Addressing barriers to accessing healthcare for the jaundiced infant may enhance timely management of NNJ and reduce the associated complications and mortality.

Comparison of the analgesic effect of inhaled lavender vs vanilla essential oil for neonatal frenotomy: a randomized clinical trial (NCT04867824). Eur J Pediatr 2022; 181:3923-3929. [PMID: 36076107 PMCID: PMC9458311 DOI: 10.1007/s00431-022-04608-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/06/2022] [Revised: 08/24/2022] [Accepted: 09/01/2022] [Indexed: 11/25/2022]
Abstract
UNLABELLED It is necessary to treat neonatal pain because it may have short- and long-term adverse effects. Frenotomy is a painful procedure where sucking, a common strategy to relieve pain, cannot be used because the technique is performed on the tongue. In a previous randomized clinical trial, we demonstrated that inhaled lavender essential oil (LEO) reduced the signs of pain during neonatal frenotomy. We aimed to find out whether inhaled vanilla essential oil (VEO) is more effective in reducing pain during frenotomy than LEO. Randomized clinical trial with neonates who underwent a frenotomy for type 3 tongue-ties between May and October 2021. Pain was assessed using pre and post-procedure heart rate (HR) and oxygen saturation (SatO2), crying time, and NIPS score. Neonates were randomized into "experimental" and "control" group. In both groups, we performed swaddling, administered oral sucrose, and let the newborn suck for 2 min. We placed a gauze pad with one drop of LEO (control group) or of VEO (experimental group) under the neonate's nose for 2 min prior to and during the frenotomy. We enrolled 142 neonates (71 per group). Both groups showed similar NIPS scores (2.02 vs 2.38) and crying times (15.3 vs 18.7 s). We observed no differences in HR increase or in SatO2 decrease between both groups. We observed no side effects in either of the groups. CONCLUSIONS We observed no appreciable difference between LEO and VEO; therefore, we cannot conclude which of them was more effective in treating pain in neonates who underwent a frenotomy. TRIAL REGISTRATION This clinical trial is registered with www. CLINICALTRIALS gov with NCT04867824. WHAT IS KNOWN • Pain management is one of the most important goals of neonatal care as it can have long-term neurodevelopmental effects. • Lavender essential oil can help relieve pain due to its sedative, antispasmodic, and anticolic properties. WHAT IS NEW • Lavender and vanilla essential oils are safe, beneficial, easy to use, and cheap in relieving pain in neonates who undergo a frenotomy for type 3 tongue-ties.

Abstract
BACKGROUND Neonatal pain may affect long-term neurodevelopment and must be treated. Frenotomy is a painful procedure wherein a common strategy to relieve pain (sucking) cannot be used because the technique is performed on the tongue. Lavender essential oil (LEO) has sedative and antispasmodic properties and has been successfully used to treat pain during heel puncture and vaccination. Our aim was to demonstrate if the use of inhaled LEO is effective in reducing pain during frenotomy in healthy, full-term neonates. METHODS We conducted a randomized clinical trial in neonates who underwent a frenotomy between August 2020 and April 2021. We assessed pain using pre and post-procedure heart rate and oxygen saturation, crying time and Neonatal Infant Pain Scale (NIPS) score. Patients with type 3 tongue tie were randomized into the "experimental group" and "control group". In both groups, we performed swaddling, administered oral sucrose, and let the newborn suck for two minutes. In the experimental group, we also placed a gauze pad with one drop of LEO under the neonate's nose for two minutes prior to and during the frenotomy. RESULTS We enrolled 142 patients (71 per group). The experimental group showed significantly lower NIPS scores (1.88 vs 2.92) and cried almost half the amount of time (14.8 vs. 24.6 seconds, P = 0.006). Comparing with the control group, we observed no side effects in either of the groups. CONCLUSIONS We observed a significant decrease in crying time and lower NIPS scores in the neonates who received inhaled LEO and underwent a frenotomy for type 3 tongue-ties. Thus, we recommend using inhaled LEO during neonatal frenotomies.

Abstract
In skin and wound research the instrumental measurement of skin function is established. Despite the widespread use, empirical evidence about measurement errors is widely lacking. The aim of this study was to measure reliability and agreement of skin temperature, transepidermal water loss, epidermal hydration, and erythema at the heel and sacral skin. Four experienced researchers performed skin measurements in 15 subjects. Lowest reliability was observed for transepidermal water loss at the sacral skin (ICC (1) 0.46 (95% CI 0.00‐0.78)) and highest for skin temperature at the heel skin (ICC (1) 0.99 (95% CI 0.99‐1.00)). Lowest Standard Errors of Measurement were calculated for skin temperature measurements at the heels (0.11°C) and highest for erythema measurements at the sacral skin (26.7 arbitrary units). There was a clear association between variability of estimates and reliability coefficients. Single measurements of skin temperature, stratum corneum, and epidermal hydration at the sacral and heel skin areas can be used in clinical research and practice. Means of at least two measurements should be used for estimating transepidermal water loss and erythema. Evidence is needed to inform researchers about relative and absolute measurement errors of commonly applied instruments and measurements in skin and wound research.

Reliability of transcutaneous bilirubin determination based on skin color determined by a neonatal skin color scale of our own. Eur J Pediatr 2021; 180:607-616. [PMID: 33409587 DOI: 10.1007/s00431-020-03885-0] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2020] [Revised: 11/13/2020] [Accepted: 11/20/2020] [Indexed: 10/22/2022]
Abstract
Measurement of transcutaneous bilirubin (TcB) is widely used to estimate serum bilirubin (SB). However, its reliability depending on skin tone is still controversial. Ethnic classification does not correlate well with skin tone. We aimed to determine the reliability of transcutaneous bilirubin in a multiethnic population based on skin color according to our neonatal skin color scale. We conducted a prospective, observational study comparing SB and TcB among different skin colors. With the blood sample routinely obtained at 48-72 h for the screening of inborn errors of metabolism, we determined SB and TcB with a jaundice meter. We obtained data from 1359 newborns (color 1 337, color 2 750, color 3 249, color 4 23) and analyzed 1549 dyads SB/TcB. Correlation between TcB and serum bilirubin was very good (R2 = 0.908-0.956), globally and by color group, with slight differences between darker and lighter skin colors. Bland-Altman plots showed different mean bias depending on skin color. Conclusions: Our study not only supports the reliability of TcB to assess SB regardless of skin color, but also supports the fact that TcB tends to overestimate SB in a higher degree in dark-skinned neonates. This may help reduce the number of blood samples for newborns. What is Known: • Jaundice meters are extensively used to diagnose neonatal hyperbilirubinemia, although controversies exist on their reliability depending on skin color. • Only a few studies have analyzed their accuracy in multiethnic populations, but none has used a validated neonatal skin color scale. What is New: • We verified correlation between serum and transcutaneous bilirubin in a multiethnic population depending on skin color after classifying our neonates into color groups with our own validated neonatal skin color scale.
