Urine soluble TLR4 levels may contribute to predict urinary tract infection in children: the UTILISE Study.

BACKGROUND: One of the most common bacterial infections in childhood is urinary tract infection (UTI). Toll-like receptors (TLRs) contribute to immune response against UTI recognizing specific pathogenic agents. Our aim was to determine whether soluble TLR4 (sTLR4), soluble TLR5 (sTLR5) and interleukin 8 (IL-8) can be used as biomarkers to diagnose UTI. We also aimed to reveal the relationship between urine Heat Shock Protein 70 (uHSP70) and those biomarkers investigated in this study. METHODS: A total of 802 children from 37 centers participated in the study. The participants (n = 282) who did not meet the inclusion criteria were excluded from the study. The remaining 520 children, including 191 patients with UTI, 178 patients with non-UTI infections, 50 children with contaminated urine samples, 26 participants with asymptomatic bacteriuria and 75 healthy controls were included in the study. Urine and serum levels of sTLR4, sTLR5 and IL-8 were measured at presentation in all patients and after antibiotic treatment in patients with UTI. RESULTS: Urine sTLR4 was higher in the UTI group than in the other groups. UTI may be predicted using 1.28 ng/mL as cut-off for urine sTLR4 with 68% sensitivity and 65% specificity (AUC = 0.682). In the UTI group, urine sTLR4 levels were significantly higher in pyelonephritis than in cystitis (p < 0.0001). Post-treatment urine sTLR4 levels in the UTI group were significantly lower than pre-treatment values (p < 0.0001). CONCLUSIONS: Urine sTLR4 may be used as a useful biomarker in predicting UTI and subsequent pyelonephritis in children with UTI.

Social-emotional and behavioural problems in young children of healthcare worker mothers during the COVID-19 outbreak: a case-control study.

BACKGROUND: The pandemic has had a significant impact on the daily lives of children and their families, particularly the children of health care workers, due to changes in family routines as a result of their parents' work schedules. We aimed to explore the socioemotional and behavioural (SEB) problems of children of healthcare worker mothers (HCWM) during the COVID-19 pandemic and compare them with age-matched children and their mothers from other occupations. METHOD: A case-control study design was applied, and a snowball approach was used to enrol volunteered participants aged between 6 and 36 months of age, through a Google survey. We used the Brief Infant-Toddler Social and Emotional Assessment (BITSEA) questionnaire to assess children's SEB problems and a Brief Symptom Inventory (BSI) to evaluate the psychological distress of mothers. Differences in BITSEA, BSI and MSPSS scores were examined using chi-square and Mann-Whitney U tests, as appropriate. A logistic regression model was used to identify independent predictors of children's behavioural and emotional problems. RESULTS: In total, 600 questionnaires were analysed. It was observed that children in the HCWM group were separated from their mothers more often and for longer periods of time than their counterparts (p < 0.010, p = 0.002). Changes in the child's structured outdoor activities during the pandemic period were more likely to be observed in the HCWM group (p < 0.05). The percentage of children with the BITSEA problem subscale above the subclinical cut-off, externalizing and dysregulation scores were significantly higher in the HCWM group (p = 0.044, p = 0.031, and p = 0.016). Moreover, each point increase in BSI global index scores (p < 0.001, RR:3.34, 95%CI:1.91-5.82) was found as a risk factor for clinically significant SEB problems. CONCLUSION: Overall, the current study suggests HCWM's have experienced occupational inequality, and young children of HCWM's were at increased risk for externalizing and dysregulation problems during the pandemic. Maternal psychological stress had a significant impact on their children's socio-emotional well-being.

Urinary HSP70 improves diagnostic accuracy for urinary tract infection in children: UTILISE study.

BACKGROUND: The accuracy of conventional urinalysis in diagnosing urinary tract infection (UTI) in children is limited, leading to unnecessary antibiotic exposure in a large fraction of patients. Urinary heat shock protein 70 (uHSP70) is a novel marker of acute urinary tract inflammation. We explored the added value of uHSP70 in discriminating UTI from other infections and conditions confused with UTI. METHODS: A total of 802 children from 37 pediatric centers in seven countries participated in the study. Patients diagnosed with UTI (n = 191), non-UTI infections (n = 178), contaminated urine samples (n = 50), asymptomatic bacteriuria (n = 26), and healthy controls (n = 75) were enrolled. Urine and serum levels of HSP70 were measured at presentation in all patients and after resolution of the infection in patients with confirmed UTI. RESULTS: Urinary (u)HSP70 was selectively elevated in children with UTI as compared to all other conditions (p < 0.0001). uHSP70 predicted UTI with 89% sensitivity and 82% specificity (AUC = 0.934). Among the 265 patients with suspected UTI, the uHSP70 > 48 ng/mL criterion identified the 172 children with subsequently confirmed UTI with 90% sensitivity and 82% specificity (AUC = 0.862), exceeding the individual diagnostic accuracy of leukocyturia, nitrite, and leukocyte esterase positivity. uHSP70 had completely normalized by the end of antibiotic therapy in the UTI patients. Serum HSP70 was not predictive. CONCLUSIONS: Urine HSP70 is a novel non-invasive marker of UTI that improves the diagnostic accuracy of conventional urinalysis. We estimate that rapid urine HSP70 screening could spare empiric antibiotic administration in up to 80% of children with suspected UTI.

Macrocephaly diagnosed during well child visits.

BACKGROUND: The measurement of head circumference (HC) provides valuable anthropometric data for a child's growth during well child visits. There are few studies on the characteristics of macrocephaly (MC) diagnosed during well child visits. The aim of this study was to identify the characteristics of children with MC diagnosed during the well-child visits. METHODS: This descriptive clinical study was carried out in the well child unit of a medical faculty hospital. The health records of all children who were followed up between 2004 and 2014 were reviewed. The records of children with the diagnosis of MC were evaluated. All children with MC had cranial ultrasonography, measurement of parental HC, and biochemistry. The HC measurements were carried out until 3 years of age in the unit. RESULTS: Ninety of 9,758 children (0.9%) had the diagnosis of MC. Of these children, 61% were male. Mean age at diagnosis was 2.7 months. The majority of children (63.3%) had familial MC. The other leading findings were isolated MC and hydrocephalus: two of eight children with hydrocephalus had delayed neuromotor development. CONCLUSION: MC was not rare in the present well child unit population. The evaluation of parental HC and cranial ultrasonography might be important for the differential diagnosis.

Non-dipping phenomenon in children with monosymptomatic nocturnal enuresis.

PURPOSE: Monosymptomatic nocturnal enuresis is a common disorder seen in childhood, and many factors play a role in its etiopathology to varying degrees. The aim of our study was to investigate the possible association between nocturnal enuresis and 24-h blood pressure profiles of enuretic children. METHODS: A total of 45 children ranging in age from 6 to 15 years with monosymptomatic nocturnal enuresis and 22 age-matched healthy controls were enrolled in our study. The blood pressure measurement was made at 30-min intervals during a 24-h period via an ambulatory blood pressure measurement device. Both groups underwent medical tests that included a complete blood count, blood biochemistry profile, urinalysis and blood renin-aldosterone levels, and all study subjects received an abdominal ultrasound. RESULTS: Statistically significant high nocturnal blood pressure levels were observed in our patients with monosymptomatic nocturnal enuresis compared with the control group (p < 0.05). The mean values of the day-to-night difference (dipping) in the systolic and diastolic blood pressure of the patients were significantly lower than those of control group (p < 0.05). CONCLUSION: Nocturnal enuresis should not only be accepted as a urinary system disorder. Possible systemic causative factors have to be examined, especially in patients that are resistant to first-line therapy. Based on the results of our study, we deduce that one of the factors that plays a role in the pathogenesis of enuresis nocturna is a non-dipping blood pressure profile (the "non-dipping" phenomenon).

Nipple Vasospasm of Nursing Mothers.

Background: Nipple vasospasm is a painful cutaneous vasoconstriction that nursing mothers experience after breastfeeding. Case presentations: In this case series, we present the common features and management of nipple vasospasm in nursing mothers. Discussion: The diagnosis of vasospasm relies on the doubt of physician or the breastfeeding consultant and observation of the color change of the nipple. Persistent nipple and breast pain in breastfeeding is often attributed to Candida albicans; thus, many mothers receive antifungal therapy before the diagnosis. Conclusions: Timely diagnosis also prevents unnecessary antimicrobial treatments. Precise and rapid diagnosis is crucial, as pain is a risk factor for cessation of breastfeeding and its exclusivity.

Association Between Infant Sleep Location and Breastfeeding.

Objective: Studies have shown that mothers sleeping with their babies have longer breastfeeding duration. Bedsharing (BS) is thought to be a risk factor for Sudden Infant Death Syndrome. The aim was to investigate the frequency of BS and roomsharing (RS) and the effect of those on breastfeeding during the first 2 years of life. Also to evaluate risk-bearing situations regarding sleep environment. Methods and Study Design: This is a cross-sectional study, with retrospective cohort features for the evaluation of some data. The setting was a Well-Child Clinic at Bakirköy Research and Training Hospital. The children were followed from the first month until survey. Feeding history was collected retrospectively from child health records. Parents were surveyed concerning sleeping location and sleeping arrangements with a questionnaire. The study encompassed 351 children and their families. Results: The rate of exclusive breastfeeding was found to be 50.2% for the first 6 months of life and BS increased in exclusively breastfed infants. When breastfeeding continued after 6 months, the trend of increased BS through months was observed. RS, BS, and breastsleeping rates were 80.6%, 22.8%, 56.1%, respectively, in the whole cohort. Working mothers and mothers >35 years of age were significantly more likely to bedshare. Cigarette smoking in BS parents was identified as a child health risk. Unsafe sleep environment was found in 72.4% of the group. Conclusions: BS increases breastfeeding for the first 6 months. Families need guidance on safe sleeping practices and should be advised regarding avoidable risks and unsafe situations in BS. Parents should be counseled to make informed decisions.

Academy of Breastfeeding Medicine Position Statement: Breastfeeding As a Basic Human Right.

A central goal of the Academy of Breastfeeding Medicine is the development of clinical protocols for managing common medical problems that may impact breastfeeding success. These protocols serve only as guidelines for the care of breastfeeding mothers and infants and do not delineate an exclusive course of treatment or serve as standards of medical care. Variations in treatment may be appropriate according to the needs of an individual patient. The Academy of Breastfeeding Medicine recognizes that not all lactating individuals identify as women. Using genderinclusive language, however, is not possible in all languages and all countries and for all readers. The position of the Academy of Breastfeeding Medicine (https://doi.org/10.1089/bfm.2021.29188.abm) is to interpret clinical protocols within the framework of inclusivity of all breastfeeding, chestfeeding, and human milk-feeding individuals.

Rusty Pipe Syndrome and Review of Literature.

Presence of blood in colostrum may change the color of breast milk and it is known as "rusty pipe syndrome." It may resolve within days, but it may be a barrier for exclusive breastfeeding. Knowledge of "rusty pipe syndrome" among health professionals is very helpful in the management of breastfeeding initiation.

Risk Factor Assessment and a Ten-Year Experience of DDH Screening in a Well-Child Population.

AIM: Risk based screening for developmental dysplasia of the hip (DDH) with ultrasound is common. However, risk factors vary from one country to the other since data are insufficient to give clear recommendations. We aimed to evaluate the risk factors for developmental dysplasia of the hip (DDH). METHODS: In this retrospective case-control study, the health records of all children, who were followed up between 2004 and 2014 at a well-child unit, were investigated for the diagnosis of DDH in Turkey. Of 9758 children, 57 children were found to have abnormal ultrasonographic findings (according to Graf classification) and these constituted the case group. As the control group, healthy 228 children who matched the case children in birth months were selected. Two groups were compared for the risk factors. RESULTS: A total of 19516 hips of 9758 children were examined for DDH. 97 hips of 57 children were found to have abnormal ultrasonographic findings. When the two groups were compared, breech presentation, multiple pregnancy, and torticollis were identified as risk factors. The female sex was also found to have a significantly high prevalence among the children in the case group. Limited hip abduction, positive Ortolani, and Barlow signs were important clinical findings in the case group. CONCLUSION: According to our findings, breech presentation, female sex, torticollis, and multiple pregnancy were found to be the risk factors of this disorder. Infants with these risk factors should be investigated carefully for DDH.

Breastfeeding experiences of female physicians and the impact of the law change on breastfeeding.

AIM: A recent improvement was made on the law regulating maternity leave in 2011 in Turkey. The leave without pay period was increased, the right to stop working on night shifts was granted, and work hours were improved. It is a known fact that returning to work is a barrier against exclusive and total breastfeeding duration. Legal regulations have crucial importance on the ability of working mothers to breastfeed their infants. The aim of this study was to calculate the effect of the improved law on breastfeeding rates among female physicians. Moreover, the difference in the duration of exclusive breastfeeding and total breastfeeding were evaluated in relation to the new law. MATERIAL AND METHODS: Three of the major hospitals in Istanbul were included in the study. A pilot study was planned and our questionnaire was tried. The actual study included 40 female physicians from each hospital. Mothers who went through antenatal or postnatal complications were excluded from the study. Infants who required intensive care after birth or were never breastfed were similarly excluded. A total of 109 female physician resident mothers' questionnaires were included in the study. RESULTS: The effects of the improvement in the law were statistically significant on the duration of maternity leave and improved working hours after returning to work (OR: 2.74 and OR: 2.52). Exclusive breastfeeding rates and total breastfeeding for more than 12 months significantly increased after the new law (OR: 4.47 and OR: 2.56). CONCLUSIONS: This study showed that legal improvements did reflect on positive outcomes. There is more to be done, especially with condition of the work places and distributing rights equally to women practicing in surgical disciplines as well. If the physicians can breastfeed after they become mothers, their experience may affect their breastfeeding advocacy and the guidance they will provide for their patients.
