RESUMO
OBJECTIVE: To describe characteristics of pediatric patients with recurrent acute mastoiditis, and to identify risk factors for this condition. STUDY DESIGN: A retrospective cohort study. SETTING: Data based on electronic medical records of the largest Health Maintenance Organization in Israel. METHODS: Children hospitalized due to acute mastoiditis during the years 2008-2018 were identified, and their diagnosis was verified. Patients with recurrent acute mastoiditis were identified and grouped, and their characteristics were outlined and compared to those of the original group to identify risk factors for recurrence. RESULTS: During the 11-year period, a total of 1115 cases of children hospitalized due to acute mastoiditis were identified with a weighted incidence rate of 7.8/100,000. Of this group, 57 patients were diagnosed with recurrence following a full clinical recovery. The incidence proportion of recurrent acute mastoiditis was 5.1% (57/1115), male-to-female ratio was 27:30, 73.4% were younger than 24 months, the median period from the first episode was 3.4 months (IQR 2.0;10.0), and 82.5% of the patients (n = 47) had a single recurrence, whereas 18.5% (n = 10) had two recurrences or more. Mastoidectomy and swelling over the mastoid area during the first episode were identified as the main risk factors for recurrent mastoiditis HR = 4.7 [(2.7-8.2), p < 0.001] and HR = 2.55 [(1.4-4.8), p = 0.003], respectively. Mastoidectomy was the only independent significant risk factor for recurrence in a multivariate analysis. CONCLUSIONS: Mastoidectomy and swelling over the mastoid area during the first episode of acute mastoiditis were found strongly related independent risk factor for future recurrent episodes of acute mastoiditis.

Medication overuse headaches are a frequent phenomenon observed in individuals suffering from chronic headaches. It arises due to the excessive consumption of pain-relief medications, resulting in the escalation and continuous persistence of headache symptoms. Nevertheless, the prevalence and distinctive characteristics of medication overuse headaches in the pediatric population have not been comprehensively explored. The primary objective of this research is to delineate the features of medication overuse headaches in children, particularly emphasizing the investigation of its epidemiology and the diagnostic patterns for headaches. We conducted a retrospective study and analyzed the medical records of children and adolescents who were evaluated at the outpatient pediatric headache clinic at the Bnai Zion Medical Center for headaches during the period spanning 2007 to 2017. Our study encompassed a cohort of 1008 patients experiencing headaches. Among these participants, 268 individuals (26.6%) were diagnosed with migraine, 250 (24.8%) exhibited tension-type headaches (TTH), and 490 (48.6%) were classified as having undifferentiated headaches. Out of the whole group, 65 had chronic headaches: 35 (54%) with migraine, 20 (30%) with tension-type headaches (TTH), and 10 (15%) with the undifferentiated headache of childhood, with the majority (73%) being female. In summary, medication overuse headaches are a prevalent issue among children grappling with chronic headaches. Intriguingly, they appear to be more pronounced within the tension-type headache (TTH) group compared to migraine sufferers and exhibit a higher prevalence among females. This study underscores the significance of early detection and careful management of medication overuse headaches in pediatric cases, shedding light on its distinct characteristics in the realm of childhood headache disorders. Further research is warranted to elucidate the underlying factors contributing to the observed gender disparity and the distinct prevalence rates among different headache subtypes.
RESUMO
The aim of our study was to evaluate the long-term outcomes of pediatric migraine and TTH in a clinical setting. We conducted a cohort study. Pediatric patients who visited the pediatric neurology clinic due to diagnoses of migraine or TTH were contacted by phone 8-10 years after their initial diagnosis and interviewed about their outcomes. Of 147 children, we were able to reach 120 (81%) patients. Of these 120 patients, 59 were seen initially due to migraine and 61 due to TTH. For the migraine patients, headaches improved in 48 (81.4%) and worsened in four (6.8%). Regarding diagnosis at follow-up, 59% still had migraine, 17% had TTH, and 23% were headache-free. Aura and photophobia were significantly associated with persistence of a migraine diagnosis. For the TTH patients, headaches improved in 49 (81.7%) and worsened in nine (15.0%). Regarding diagnosis at follow-up, 36.7% still had TTH, 18.3% had migraine, and 45% were headache-free. Of the patients with TTH, 36.7% retained their initial diagnosis compared to 59.3% among the migraine patients. Most pediatric patients presenting with migraine or TTH will experience a favorable outcome over 10 years, with TTH patients having twice the chance of complete resolution.
RESUMO
INTRODUCTION: The International Headache Society criteria were written in order to help physicians establish a headache diagnosis. However, sometimes children with headache do not seem to fit any diagnosis. The purpose of our study was to assess the application of the criteria in a clinical setting. METHODS: Medical records of children referred for primary headache to the pediatric neurology clinic at Bnai Zion Medical Center from 2008 to 2017 were assessed. RESULTS: A total of 989 patients (range 6-18 years; 53% female) were assessed at our neurology clinic. Twenty-four percent (n = 241) were diagnosed with tension-type headache, 26% (n = 256) with migraine, and 4.5% (45) with mixed headache. In 41.5% (410), we were unable to reach a specific diagnosis. No differences in gender or age were found between the groups. Children in the migraine group used more analgesic treatments to stop the headache attacks compared with the tension-type headache group (50% vs 38%, P = .001). Patients diagnosed with tension-type headache reported having more emotional difficulties (P = .001). No significant differences were found in headache characteristics (ie, location, sidedness, character), frequency, or intensity between the younger children (ages 6-11) and the adolescents (ages 12-18) within either the tension-type headache or migraine groups. CONCLUSIONS: Retrospective application of International Headache Society criteria in a large cohort of children with headaches failed to diagnose a specific type of headache in 41.5% of children. Migraine and tension-type headache were equally prevalent, and both constituted a major burden on our patients' everyday lives. We found no major differences in frequency, intensity, and characteristics of pain between younger children and adolescents.

BACKGROUND: Reliably distinguishing bacterial from viral infections is often challenging, leading to antibiotic misuse. A novel assay that integrates measurements of blood-borne host-proteins (tumor necrosis factor-related apoptosis-inducing ligand, interferon γ-induced protein-10, and C-reactive protein [CRP]) was developed to assist in differentiation between bacterial and viral disease. METHODS: We performed double-blind, multicenter assay evaluation using serum remnants collected at 5 pediatric emergency departments and 2 wards from children ≥3 months to ≤18 years without (n = 68) and with (n = 529) suspicion of acute infection. Infectious cohort inclusion criteria were fever ≥38°C and symptom duration ≤7 days. The reference standard diagnosis was based on predetermined criteria plus adjudication by experts blinded to assay results. Assay performers were blinded to the reference standard. Assay cutoffs were predefined. RESULTS: Of 529 potentially eligible patients with suspected acute infection, 100 did not fulfill infectious inclusion criteria and 68 had insufficient serum. The resulting cohort included 361 patients, with 239 viral, 68 bacterial, and 54 indeterminate reference standard diagnoses. The assay distinguished between bacterial and viral patients with 93.8% sensitivity (95% confidence interval: 87.8%-99.8%) and 89.8% specificity (85.6%-94.0%); 11.7% had an equivocal assay outcome. The assay outperformed CRP (cutoff 40 mg/L; sensitivity 88.2% [80.4%-96.1%], specificity 73.2% [67.6%-78.9%]) and procalcitonin testing (cutoff 0.5 ng/mL; sensitivity 63.1% [51.0%-75.1%], specificity 82.3% [77.1%-87.5%]). CONCLUSIONS: Double-blinded evaluation confirmed high assay performance in febrile children. Assay was significantly more accurate than CRP, procalcitonin, and routine laboratory parameters. Additional studies are warranted to support its potential to improve antimicrobial treatment decisions.

OBJECTIVE: Emotional intelligence (EI) is the individual's ability to perceive, understand and manage emotion and to understand and relate effectively to others. We examined the degree to which EI training may be associated with a change in EI among different medical personnel and patient satisfaction. DESIGN, SETTING AND PARTICIPANTS: The EI of 17 physicians and 10 nurses in paediatric ward was prospectively evaluated with Bar-On's EI at baseline and after 18â months. 11 physicians who did not undergo the intervention served as controls. INTERVENTIONS: The intervention consisted of a training programme comprising group discussions, simulations and case studies. MAIN OUTCOMES AND MEASURES: Pre-emotional quotient inventory (EQ-i) and post-EQ-i scores and patient satisfaction surveys of nurse and physicians pre-intervention and post-intervention were analysed. RESULTS: The mean overall EI score of the study sample rose from 99.0±9.6 (both plus and minus mathematical operations standing for SD) at baseline to 105.4±10 (p<0.000) after 18â months, with the most robust increase (nearly 6%; p<0.003) manifested among physicians. In contrast, the control group's EI scores did not change over this period. Within the intervention group, physicians displayed a statistically significant increase in three of the five EI dimensions, compared with only one of the five EI dimensions for nurses. Patient satisfaction scores relating to physician care rose from 4.4 pre-intervention to 4.7 post-intervention (p=0.03). CONCLUSION: An EI intervention led to an overall increase in EI scores, with a significant improvement in patient satisfaction. These findings suggest important potential benefits for both staff and their patients.

There is a growing need for health care professionals to extend their knowledge in adolescent health care. Formal training curricula in adolescent medicine have been established in the United States, Canada, and Australia, yet many other countries have developed shorter training programs to enable interested physicians to further pursue knowledge and practical experience in delivering improved quality health care for adolescents. The Israeli experience in building an infrastructure that allows students and physicians to learn about adolescent medicine and to train in the field is described. It includes a series of lectures and seminars for medical students during medical school and at the clinical rotations in pediatric wards; the development of hospital-based and community-based multidisciplinary adolescent health services where residents can practice adolescent health care; a 3-year diploma course in adolescent medicine for specialists in pediatrics and family medicine; mini courses in adolescent medicine for pediatricians and family practitioners working in community settings; and a simulated patient-based program regarding communication with adolescents, aimed for all professional levels - medical students, residents, and specialists. This infrastructure has been developed to create a leading group of physicians, who are able to operate adolescent clinics and to teach adolescent medicine. Recently, a formal fellowship program in adolescent medicine has been approved by the Scientific Council of the Israel Medical Association. The Israeli experience described here could be applied in countries, where formal training programs in adolescent health care are not yet established.

BACKGROUND: The three-year pre-medical programme 'Becoming a Physician' focuses on different aspects of medical professionalism. Objectives are to increase awareness and sensitivity to disadvantaged populations, and practise sensitive effective communication skills. METHODS: The curriculum includes: (1) Visits to treatment centres for people with special needs, mental illnesses, substance abuse issues, physically or sexually abused, and prisoners. Students tour the facility, hold discussions with residents, and discuss ethical professional interrelations to the medical world. Students then write 'reflective diaries' summarizing their thoughts and emotions. (2) Participation in a communication course that focuses on learning by practising patient-oriented communication. Qualitative data were collected from three sources: reflective diaries, students' course evaluations, and interviews with the students' tutors. RESULTS: Data indicated that the students were very satisfied with the programme. They indicated an increase in awareness of the special needs of diverse populations, and in the sense of efficacy for conducting interviews tailored to patients' needs. Tutors reported a sense of 'personal growth' following their role as mentors. REFLECTIONS: Interactions of medical students with diverse populations, when accompanied by appropriate feedback mechanisms and strengthening of communication skills, can improve awareness and sensitivity to patients' special needs. This could help students become more sensitive and thoughtful physicians.
RESUMO
BACKGROUND: Primary headaches are one of the most common disorders of childhood, with migraine and tension type headaches (TTHs) being the most frequent ones. In spite of their prevalence, there is paucity of knowledge regarding the underlying pathophysiological mechanisms that cause headaches and regarding the unique aspects of headaches in children and adolescents. AIM: To review the literature and summarize the knowledge regarding clinical features, diagnosis and management of primary headache in children and adolescents, mainly migraine and TTH. RESULTS AND CONCLUSIONS: Most of our current knowledge regarding primary headaches in children and adolescents is driven from extrapolations from studies that were conducted with adult patients. Therefore, it needs to be validated for the different age groups. Migraines may be diagnosed effectively based on the 2nd edition of the International Classification of Headache Disorders (ICHD-II), however, TTH is diagnosed mainly by the absence of features found in other headache types. Treatment strategies for primary headaches vary according to patient's age, family structure, culture and beliefs, headache diagnosis, and based on the disability the headache imposes on the patient's daily living. It was shown that a multidisciplinary approach, that includes continuing counseling, education, and reassurance, in combination with pharmacological and non-pharmacological treatment, is an effective strategy for children and adolescents suffering from primary headaches. Further studies are needed to enrich our knowledge about the pathophysiological mechanisms that cause headaches in children and adolescents and to develop efficient strategies to alleviate their burden.

The purpose of the present study was to evaluate the relationship between headaches and physical and sexual abuse. A self-administered, anonymous questionnaire was presented to 2088 tenth grade students in Northern Israel. Participants were Jews and Arabs between the ages of 15 to 16 years. Arab adolescents comprised 55% of the analyzed sample and adolescent Jews 45%. With regard to gender, 56% of participants were females. Of the Arab participants, 18.6% reported having frequent headaches, less than that reported in the Jewish group (27.9%). Jewish girls who were physically abused during childhood had a higher prevalence of frequent headaches (55% vs 33% P < .001). Jewish students who reported being sexually abused had higher headache prevalence as well (44.4% vs 27.3% P = .05). In conclusion, adolescents who reported to have been physically or sexually abused report a higher prevalence of headache compared to their peers.

BACKGROUND: Primary headaches and Learning difficulties are both common in the pediatric population. The goal of our study was to assess the prevalence of learning disabilities and attention deficit disorder in children and adolescents with migraine and tension type headaches. METHODS: Retrospective review of medical records of children and adolescents who presented with headache to the outpatient pediatric neurology clinics of Bnai-Zion Medical Center and Meyer Children's Hospital, Haifa, during the years 2009-2010. Demographics, Headache type, attention deficit disorder (ADHD), learning disabilities and academic achievements were assessed. RESULTS: 243 patients met the inclusion criteria and were assessed: 135 (55.6%) females and 108 (44.4%) males. 44% were diagnosed with migraine (35.8% of the males, 64.2% of the females, p = 0.04), 47.7% were diagnosed with tension type headache (50.4% of the males, 49.6% of the females). Among patients presenting with headache for the first time, 24% were formerly diagnosed with learning disabilities and 28% were diagnosed with attention deficit disorder (ADHD). ADHD was more prevalent among patients with tension type headache when compared with patients with migraine (36.5% vs. 19.8%, p = 0.006). Poor to average school academic performance was more prevalent among children with tension type headache, whereas good to excellent academic performance was more prevalent among those with migraine. CONCLUSIONS: Learning disabilities and ADHD are more common in children and adolescents who are referred for neurological assessment due to primary headaches than is described in the general pediatric population. There is an association between headache diagnosis and school achievements.

BACKGROUND: Headache is the most common cause for chronic or recurrent pain in childhood and adolescence. Chronic pain may have a long-term effect on adolescents. It might contribute to functional limitations, such as poor school attendance, and it may adversely affect development of healthy social relationships. The aim of our study was to examine the cross- ethnic variation in the prevalence of headache in a non- clinical sample of adolescents in Northern Israel and to learn about its association to other somatic complaints. METHODS: A self-administered, anonymous questionnaire was presented to 2,088 tenth grade students attending 19 high-schools in Northern Israel (all the public high schools within two districts). Participants were Jews and Arabs, the latter including Muslim, Christians, and Druze, aged 15 to 16. Parental and student consent was obtained from all participants. The study was approved by the IRB of our institution. RESULTS: All 2088 questionnaires were returned although only 2019 were usable and analyzed. Arab adolescents comprised 55% (1117) of the analyzed sample and Jews 45% (902), 56% of participants were girls. Of the Arab participants, 18.6% reported having frequent headaches (girls 25.3%, boys 9.1%, P<0.0001) much less than their Jewish peers (P<0.0001) among whom 27.9% reported having frequent headaches (girls 35.6%, boys 19% P<0.0001). Other somatic complaints such as abdominal pain, palpitations, disordered sleep and fatigue were more frequent in adolescents (Jews and Arabs, girls and boys) who suffered from headaches than in their peers who did not report having headaches (P<0.0001), the same pattern observed in the Jewish and the Arab group. CONCLUSIONS: Headache is a frequent complaint among adolescents in Northern Israel. Jewish adolescents reported having headaches more frequently than their Arab peers. Those who suffered from frequent headaches also reported having significantly more other somatic complaints than adolescents without headaches. Girls had more somatic complaints then boys in the two ethnic groups.

Pelvic inflammatory disease (PID) is a common disorder affecting sexually active adolescents. The Centers for Disease Control and Prevention (CDC) and European CDC report Chlamydia trachomatis as the most common sexually transmitted infection and one of the main etiological agents causing PID. C. trachomatis' and PID's high prevalence may be attributed to multiple factors including high-risk sexual behaviors, sensitive laboratory diagnostics (polymerase chain reaction), and the introduction of chlamydia screening programs. The pathogenesis of C. trachomatis infection is complex with recent data highlighting the role of toll-like receptor 2 and four in the mediation of the inflammatory cascade. The authors review the etiology of the disease, explore its pathogenesis, and discuss a variety of strategies that may be implemented to reduce the prevalence of C. trachomatis including: (a) behavioral risk reduction, (b) effective screening of asymptomatic females, (c) targeted male screening, (d) implementation of a sensitive, rapid, self-administered point-of-care testing, and (e) development of an effective vaccine.

OBJECTIVE: To examine the effect of malnutrition due to anorexia nervosa (AN) on venous blood gases of adolescents with AN hospitalized for medical stabilization. METHOD: This retrospective study included 45 adolescents with recent onset (<1 year) AN diagnosed by DSM-IV criteria and excluded subjects with a history of lung disease. RESULTS: Mean (± SD) age at hospitalization was 15.0 ± 2.0 years; time from onset of symptoms was 6.8 ± 3.0 months; body mass index (BMI) was 15.2 ± 1.5 kg/m(2) ; and minimal nocturnal heart rate (MNHR) was 39.8 ± 7.2 beats/min. On admission, pH was 7.32 ± 0.02, pCO(2) was 53.8 ± 4.6 mm Hg, and HCO(3) was 28.1 ± 2.1 mEq/l. Significant changes (p < .001) occurred during the relatively short hospitalization (9.7 ± 5.1 days): venous pH increased, pCO(2) decreased, HCO(3) decreased, MNHR increased, and heart rate orthostasis decreased. Mild respiratory acidosis (pH < 7.35 and pCO(2) > 45 mm Hg) was observed in 78% of the patients on admission and only in 35% at discharge (p = .0003). Positive correlations were found between % of weight loss and pCO(2) on admission and between BMI on admission and the delta pCO(2) during hospitalization. DISCUSSION: Mild respiratory acidosis is common in adolescents with recently diagnosed AN, hospitalized for medical stabilization. Respiratory acidosis improves with bed rest and refeeding. The clinical significance of these findings should be further evaluated.

OBJECTIVE: To examine the effects of malnourishment on the respiratory system of adolescents with anorexia nervosa (AN) hospitalized for medical stabilization. METHOD: Prospective study. STUDY GROUP: hospitalized adolescents with recent onset (<1 year) AN. CONTROL GROUP: adolescents hospitalized for other diagnoses. Excluded: participants with lung disease. RESULTS: Patients' characteristics (mean ± SD) for the AN (n = 16) and the control group (n = 13) on admission were: age: 15.0 ± 1.7 vs. 15.2 ± 1.4 years, p = 0.7; body mass index (BMI): 15.5 ± 2.3 vs. 19.8 ± 2.9 kg/m², p < 0.001; venous pH 7.34 ± 0.02 vs. 7.38 ± 0.03, p < 0.001; PCO2 53.3 ± 4.1 vs. 42.5 ± 3.1 mm Hg, p < 0.001; and HCO3 28.7 ± 2.0 vs. 25.3 ± 2.4 meq/L, p < 0.001, respectively. There were no significant differences in nocturnal respiratory rates, pulse-oximetry oxygen saturations, or end-tidal CO2. Pulmonary function tests (PFTs) in adolescents with AN revealed no obstructive, restrictive, or significant pulmonary vascular disease except for lower peak expiratory flow rates (PEFRs). During hospitalization (12.3 ± 3.8 days), their weight, BMI, mean nocturnal heart rate, and respiratory rate increased significantly, while their venous PCO2 and HCO3 decreased significantly without significant changes in PFTs. DISCUSSION: Adolescents with recent onset AN, admitted for medical stabilization, demonstrate hypercapnia despite normal PFTs, except for decreased PEFRs. These could result from decreased respiratory muscle strength and/or abnormal control of breathing.

Anorexia nervosa (AN) commonly arises during adolescence and is associated with significant medical morbidity. Abnormalities in brain structure and function are among the most common, early, and concerning physical consequences. Advances in neuroimaging technology have played an important role in delineating the structural and functional changes found in patients with AN. Studies using computed tomography and magnetic resonance imaging have demonstrated changes in brain structure in the low-weight stages of AN. In addition, functional neuroimaging techniques have demonstrated altered brain metabolism. Debate continues as to whether these brain abnormalities are fully reversible with weight restoration. Neuropsychological research has demonstrated that cognitive dysfunction is also a common feature of AN. Multiple studies have indicated deficits in various neuropsychological domains. Whether the reported cognitive deficits are reversible with weight gain remains unknown. To date, some preliminary evidence suggests that reported cognitive deficits in patients with AN may be associated with structural brain abnormalities. This chapter reviews the current literature about neuroimaging studies and cognitive function in adolescents with AN, discusses the possible underlying mechanisms causing these changes, and explores the possible association between them.
