Background: Immune thrombocytopenia (ITP) is an autoimmune disorder of variable origin that results in bleeding and decreased platelet count. Autoimmune abnormalities have been described in patients with malignancies including non-Hodgkin's lymphoma but are rarely described in patients with Hodgkin's lymphoma.

Objectives: To describe an unusual presentation of Hodgkin's lymphoma in an unusual age and alarm pediatricians of the challenging diagnosis.  

Methods: We present two cases that highlight an unusual clinical presentation of childhood Hodgkin's lymphoma occurring at an atypical age.

Results: Over a 4-year period, two children aged 5 and 6 years were admitted for suspected ITP, both had cervical lymphadenopathy. Bone marrow examination showed no evidence of tumor or fibrosis. Biopsy of the lymph node was possible only after administration of intravenous immunoglobulins and normalization of the platelet count. Platelet counts increased after initiation of chemotherapy.

Conclusions: The identification of the clinical presentation of ITP as a possible presentation of Hodgkin's lymphoma is important to facilitate timely diagnosis and management.

Background: Urinary tract infection (UTI) is a common bacterial infection in children.

Early treatment may prevent renal damage in pyelonephritis. The choice of empiric antibiotic treatment is based on knowledge of the local susceptibility of urinary bacteria to antibiotics. In Israel the recommended empiric oral antibiotic treatment are First or second generation cephalosporin, trimethoprim-sulfamethoxazole or amoxicillin-clavulanic acid.

Objectives: To describe resistance rates of urine bacteria isolated from children with UTI in the community settings. Identify risk factors for resistance.

Methods: A retrospective cross-sectional study of UTI in children aged 3 months to 18 years diagnosed with UTI and treated as outpatients in a large community clinic between 7/2015 and 7/2017 with a diagnosis of UTI.

Results: A total of 989 urinary samples were isolated, 232 were included in the study. Resistance rates to cephalexin, cefuroxime, ampicillin/clavulanate and Trimethoprim-Sulfamethoxazole were 9.9%, 9.1%, 20.7%, and 16.5%, respectively. Urinary tract abnormalities and recurrent UTI were associated with an increase in antibiotic resistance rates. Other factors such as age, fever, and previous antibiotic treatment were not associated with resistance differences.

Conclusions: Resistance rates to common oral antibiotics were low compared to previous studies performed in Israel in hospital settings. First generation cephalosporins are the preferred empiric antibiotics for febrile UTI for outpatient children. Amoxicillin/clavulanate is not favorable due to resistance of over 20% and the broad spectrum of this antibiotic. Care should be taken in children with renal abnormalities as there is a worrying degree of resistance rates to the oral first line antibiotic therapy.

Background: The number of investigative esophagogastroduodenoscopies (EGD) in children has increased over several decades, despite their unclear diagnostic yields.

Objectives: To evaluate the indications for performing EGD, their diagnostic yields, and consequences on pediatric patient management.

Methods: A retrospective chart review was performed of consecutive pediatric patients aged 0–18 years, who underwent EGD between January and August 2014.

Results: During the study period, 547 EGD were performed on 478 children. The most frequent indications were suspected celiac disease, chronic non-specific abdominal pain, persistent Helicobacter pylori infection, and gastrointestinal hemorrhage. The yield of the diagnostic EGD was 59.2%, and the most common new diagnoses were celiac disease (28%), Helicobacter pylori-positive gastritis (16.5%), and Crohn’s disease (5.4%). Of the patients with documented follow-up, 74.1% reported improved symptoms. Procedures performed for chronic unexplained abdominal pain had significantly lower yields (26.2%) and only 39.3% improved at follow-up.

Conclusions: Our findings suggest a general high diagnostic yield for EGD in pediatric patients, stemming mainly from patients in whom a specific condition was suspected a priori. However, the role of the procedure in the diagnosis and management of non-specific gastrointestinal complaints was minor suggesting that EGD may be superfluous for some of these patients.

Background: The introduction of pneumococcal conjugate vaccine-13 (PCV-13) has reduced the burden of invasive pneumococcal disease.

Objective: To characterize true positive blood cultures of children who presented to our hospital following implementation of the PCV-13 vaccine.

Methods: A retrospective study was conducted on positive blood cultures of children presenting with fever from 2010–2017. Subjects were divided into two age groups: a younger group 3–36 months and an older group 3–18 years. Patients were classified as either having or not having a focus of infection at the time of their bacteremia. Pneumococcal isolates were typed at Israel's Streptococcal Reference Laboratory.

Results: The samples included 94 true positive blood cultures. Focal infection with concomitant bacteremia was more common than bacteremia without a focus both overall: 67/94 (71%) vs. 27/94 (28.7%), P <0.001 as well as in the two groups: 32/48 (66%) vs. 16/48 (33%), P = 0.02 in the younger group and 35/46 (76%) vs. 11/46 (24%), P = 0.001 in the older group. Streptococcus pneumoniae was the most common pathogen overall, 27/94 (29%), and in the younger group, 21/48 (44%), but rare in the older group, 6/46 (13%). In the latter, Brucella species predominated, 12/46 (26%), along with Staphylococcus aureus 12/46 (26%).

Conclusions: Our findings are consistent with other studies reporting decreased pneumococcal bacteremia, bacteremia primarily accompanying focal infection, and changing etiological agents among PCV-13-vaccinated children. Brucella species was prominent in older children with osteoarticular infections. Ongoing surveillance is warranted to better understand the implications of PCV-13.

Background: Temporary abdominal closure (TAC) surgical technique relates to a procedure in which the post-surgical abdominal wall remains open in certain indications. The Bogota bag (BB) technique is a tension-free TAC method that covers the abdominal contents with a sterilized fluid bag. There are very few reports of pediatric patients treated with this technique.

Objectives: To describe our institution’s 15 years of experience using the BB technique on pediatric patients.

Methods: A retrospective cohort study describing our experience treating patients with BB was conducted. The medical files of 17 pediatric patients aged 0–18 years were reviewed.

Results: Between January 2000 and December 2014, 17 patients were treated with BB at our medical center (6 females, median age 12 years). Indications for BB were a need for a surgical site re-exploration, mechanical inability for primary abdominal closure, and high risk for ACS development. Median BB duration was 5 days and median bag replacement was 2 days. Median ICU length of stay (LOS) was 10 days and hospital LOS was 27 days. The ICU admission and BB procedure was tolerated well by 6 patients who were discharged home without complications. Of the remaining 11 patients, 6 patients died during the admission (35%) and the others presented with major complications not related to the BB but to the patient's primary disease.

Conclusions: This report represents the largest series of children treated with BB. The technique is simple to perform, inexpensive, and has very few complications.

Background: Ocular trauma in the pediatric population may lead to cataract formation. Managing traumatic cataracts in a visually immature child is a major challenge and can result in poor visual outcome.

Objectives: To review our long-term surgical experience with childhood unilateral traumatic cataracts.

Methods: A retrospective observational study of children with unilateral traumatic cataracts with minimal follow-up of 5 years was conducted. Main outcomes included final visual acuity (VA) and occurrence of complications.

Results: Of the 18 children included in the study, 83% were male. Mean follow-up time was 12.5 years. Median age at injury was 7.5 years. Eleven patients (61%) presented with penetrating trauma injuries and 7 (39%) with blunt trauma. Sixteen patients (89%) had cataracts at presentation, while in two the cataracts developed during follow-up. Of the 18 total, cataract removal surgery was conducted in 16 (89%) with intraocular lens (IOL) implantation in 14 (87.5%), while 2 remained aphakic (12.5%). Two (11%) were treated conservatively. Long-term complications included IOL dislocation in 5 (36%), glaucoma in 8 (44%), and posterior capsular opacity in 10 (71%). No correlation was found between final visual acuity and the time interval between injury and IOL implantation nor between final VA and age at trauma. However, the final VA did correlate with time of follow-up.

Conclusions: Severe complications occurred in over 30% of the patients during a long follow-up (mean 12.5 years). This finding shows the importance of discussions between the operating physician and the parents regarding the prognosis and necessity of scheduled follow-up.

Background: Ophthalmic pathologies may further complicate the sensory input of patients with congenital hearing loss; however, data on children with coexisting impairment of vision and hearing is outdated, from before universal implementation of hearing screening programs.

Objectives: To examine the different ophthalmic pathologies among children with congenital sensorineural hearing loss (SNHL) before or after the introduction of a universal newborn hearing screening program (UNHSP).

Methods: Retrospective cohort study was conducted of 91 children diagnosed with congenital SNHL between 2005 and 2016 in a tertiary pediatric hospital. All patients completed an ophthalmologic examination, including assessment of visual acuity, refraction, ocular motility, slit lamp examination, and indirect funduscopy. Radiological assessment and genetic analysis were offered to all caregivers.

Results: Average age at diagnosis was 4.1 years. Nineteen children (21%) were diagnosed with an ophthalmic condition, of which the most common were refractive pathologies. Diagnosis of an ophthalmic pathology was twice as likely in the pre-UNHSP era (14 children, 27%) compared to the post-UNHSP era (5 children, 13%). Out of 91 children, 57 (63%) underwent a computed tomography scan and/or magnetic resonance imaging. Imaging was positive for structural abnormalities in 23 children (40%). There was no correlation between imaging and ophthalmic conditions. Genetic analysis was performed in 67 patients (74%).

Conclusions: The ophthalmic assessment of babies and children with congenital SNHL may yield in significant numbers of children with concomitant ophthalmic pathologies. Implementation of a UNHSP allows early diagnosis and treatment of coexisting ophthalmic and hearing conditions.

Background: Hypertrophy of the adenoids is common in children. However, the anatomical site makes the adenoids difficult to assess, and studies evaluating the subject are ambiguous, especially with regard to the use of X-ray as an evaluation tool.

Objectives: To compare medical history with clinical, radiological, and endoscopic evaluations of the adenoids and compare obstructed and non-obstructed children relative to the assessment methods.

Methods: A prospective comparative study was conducted with children who were suspected of having enlarged adenoids. All parents completed a medical history questionnaire and patients underwent clinical evaluation based on Nasal Obstruction Index (NOI) scores, radiological assessment based on the lateral neck X-ray adenoid–nasopharynx (A/N( ratio, and endoscopic evaluation based on anatomical relations. Spearman correlations were used for comparison between methods.

Results: We evaluated 36 patients, median age 5.33 years. Correlation measurements for clinical assessment and questionnaire (r = 0.582, P < 0.0001), questionnaire and endoscopy (r = 0.462, P = 0.005), and clinical assessment and nasal endoscopy (r = 0.621, P < 0.0001) were statistically significant. None of the parameters correlated with the radiological findings. A statistically significant difference was found between the obstructed and non-obstructed groups in both questionnaire (P = 0.004) and clinical assessment (P < 0.0001). However, no difference was found in X-ray measurements.

Conclusions: Lateral neck X-ray measurements were not correlated to symptoms, signs, or endoscopic findings. Therefore, medical professionals should use lateral neck radiography when considering adenoidectomy only on a highly selective basis.

Background: Pulmonary rehabilitation has shown significant benefit for patients with chronic obstructive pulmonary disease (COPD). The effect on non-COPD pulmonary patients is less well established.

Objectives: To determine whether pulmonary rehabilitation is also beneficial for non-COPD pulmonary patients.

Methods: Clinical and demographic data on non-COPD pulmonary patients who participated in our institutional pulmonary rehabilitation program between January 2009 and December 2016 were collected. Participants engaged in a 60-minute, twice-weekly, ambulatory hospital-based program lasting 12 to 24 sessions. Sessions included both endurance and muscle training as well as healthy lifestyle educational activities. The six-minute walk test (6MWT) and the St. George's Respiratory Questionnaire (SGRQ) were conducted before and after the rehabilitation program.

Result: We recruited 214 non-COPD patients, of whom 153 completed at least 12 sessions. Of these, 59 presented with interstitial lung disease (ILD), 18 with non-ILD restrictive lung defects, 25 with asthma, 30 with lung cancer, and 21 with other conditions (e.g., pulmonary hypertension, bronchiectasis) The groups demonstrated significant improvement in 6MWT and in SGRQ scores. Non-COPD patients gained a 61.9 meter (19%) improvement in the 6MWT (P < 0.0001) and 8.3 point reduction in their SGRQ score (P < 0.0001).

Conclusions: Pulmonary rehabilitation is effective in non-COPD pulmonary patients. As such, it should be an integral part of the treatment armament provided to the vast majority of those suffering from chronic respiratory disease.

Background: Horse riding has become increasingly popular in recent years and is a common activity among children. As a result, pediatric horse-related injuries are frequently encountered in emergency departments.

Objectives: To examine the characteristics of horse-related injuries in the pediatric population.

Methods: We collected and analyzed the data on all pediatric horse-related injuries presented to a tertiary hospital, level one trauma center, during the years 2006–2016.

Results: A total of 53 children with horse-related injuries were documented. Forty-two patients were male (79%) and their mean age was 11.13 ± 4.72 years. The most common mechanism of injury was falling off a horse (31 patients, 58%) and the most common type of injury was skeletal (32 patients, 60%). Head injuries occurred in 16 patients (30%) and facial injuries in 12 (23%). The mean Injury Severity Score (ISS) was 10.5 ± 6.32, and 15 patients (28%) had severe trauma (ISS > 15). Twenty-nine patients (55%) required trauma team intervention, 12 (23%) were admitted to the intensive care unit, and 24 (45%) required surgery. The mean length of hospitalization was 4.3 ± 3.14 days.

Conclusions: Our study suggests that horse-related trauma may involve serious injuries and it exhibits typical injury patterns. Young boys are at highest risk. The potential severity of these injuries merits a thorough evaluation. We suggest that these injuries be triaged appropriately, preferably to a medical facility with proper trauma capabilities.

Background: Treatment of patients with childhood growth hormone deficiency is usually terminated at the end of puberty. Follow-up into adult age is rare, even more so in patients with congenital isolated growth hormone deficiency (cIGHD).

Objectives: To assess the clinical and social characteristics of adults with cIGHD who received growth hormone (hGH) treatment in childhood.

Methods: Thirty-nine patients (23 men, 16 women) diagnosed in our clinic with cIGHD at 7 ± 4.2 years, and treated with hGH during childhood for 2–18 years, were followed into adulthood (mean age 30.7 ± 13.3 years). Ascertained detailed data were found for 32 patients.

Results: Mean ± SD height for males was 160.2 ± 10.6 cm and for females 146.4 ± 5.4 cm. All patients achieved full sexual development and 14 were married. After cessation of GH treatment and with advanced age all exhibited a progressive increase in adiposity to the degree of obesity. Twelve patients suffered from hyperlipidemia, 4 developed diabetes mellitus, and 5 have cardiovascular diseases. One patient died in an accident. None developed cancer. Of the 39 patients, 22 have an education level of high school or higher, and 2 are in special institutions. Most are employed in manual labor.

Conclusions: Patients with congenital IGHD who do not receive early and regular replacement treatment are prone to lag in achieving normal height and suffer from educational and vocational handicaps.

Background: A history of childhood sexual abuse (CSA) has been linked to a variety of physical and psychiatric illnesses, including ischemic heart disease and post-traumatic stress disorder (PTSD).

Objectives: To determine the prevalence of past CSA and re-traumatization among hospital psychiatric consultations and to determine whether a CSA group in a hospital setting shared characteristics with community samples described in the literature.

Methods: We divided 228 consecutive psychiatric consultations into two groups. One group comprised patients with a past history of CSA while the other group had no such history. Both groups were further divided into a subgroup that presented with features of re-traumatization.

Results: In the cohort, 38% described a history of CSA. Twenty patients were identified as presenting with features of re-traumatization. There were significant differences between the two groups. The patients with a history of CSA were more likely to have arrived at the emergency department (ED) during the preceding 12 months with a diagnosis of PTSD, personality disorder, and substance use disorder. There was a greater proportion of patients in the CSA group who had grown up in an ultra-Orthodox Jewish household and who currently identified as being secular.

Conclusions: The characteristics of the patients with past CSA in this study are similar to community-based samples, except for a significant gender difference. To the best of our knowledge, this study is the first to investigate CSA history during hospital ED psychiatric consultations. A history of CSA should be considered during psychiatric consultations in a general hospital ED admission.

Background: Hyperchloremia is frequent in adult surgical patients and is associated with renal dysfunction. Studies in surgical pediatric patients are lacking.

Objectives: To identify both the incidence of postoperative hyperchloremia in children undergoing surgery for idiopathic and non-idiopathic scoliosis, and the association of postoperative hyperchloremia with intraoperative fluid management and postoperative diuresis.

Methods: The records of 74 children and adolescents who underwent elective scoliosis surgery were retrospectively evaluated. The primary endpoint was the incidence of serum chloride level ≥ 110 mEq/L at the end of surgery and 12 hours postoperatively. Secondary endpoints were the type and volume of administered fluids, 12 hours postoperative diuresis, and the incidence of postoperative oliguria.

Results: Hyperchloremia occurred in 55% of the patients at the end of surgery and in 52% 12 hours postoperatively. Hyperchloremic patients received larger intraoperative volume of 0.9% NaCl diluted cell-saver blood and 10% HAES than did normochloremic patients [median (interquartile range) 6.8 (2.5–11.0) ml/kg vs. 0 (0–7.3), P = 0.003 and 10.0 (0–12.8) vs. 4.4 (0–9.8), P = 0.02, respectively]. Additionally, when compared with normochloremic patients, diuresis during the first 12 hours postoperatively was lower in hyperchloremic patients. Postoperative oliguria (urine output < 0.5 ml/kg/hr for 12 hours) was diagnosed in 7 children (9%), of whom 6 were hyperchloremic at the end of surgery.

Conclusions: Early postoperative hyperchloremia is common in children undergoing scoliosis repair surgery and may be attributed to the administration of 0.9% NaCl diluted cell-saver blood and 10% HAES. Postoperative hyperchloremia might be associated with postoperative oliguria.

Background: Fetal alcohol spectrum disorder (FASD) may be under-recognized and under-diagnosed in Israel. Fewer than 10 FASD diagnoses were reported between 1998 and 2007; however, several hundred diagnoses have been made since. Furthermore, less than 10% of surveyed Israeli pediatricians reported adequate knowledge of FASD.

Objectives: To determine the prevalence of suspected FASD, to establish a database as a starting point for epidemiological studies, and to develop FASD awareness for health, social, and educational services.

Methods: A chart review was conducted at an educational facility for children and adolescents with behavioral and learning challenges. The following information was extracted: adoption status, history of alcohol/drug abuse in the biological mother, medical diagnoses, medication use, and information regarding impairment in 14 published neurobehavioral categories. Subjects were classified as: category 1 (highly likely FASD) – impairment in three or more neurobehavioral categories and evidence of maternal alcohol abuse was available; category 2 (possible FASD) – impairment in three or more neurobehavioral categories and evidence to support maternal substance abuse (type/time unspecified); and category 3 (unconfirmed likelihood of FASD) – impairment in three or more neurobehavioral categories and no information regarding the biological family.

Results: Of 237 files analyzed, 38 subjects (16%) had suspected FASD: 10 subjects (4%) in category 1, 5 (2%) in category 2, and 23 (10%) in category 3. Twenty-seven subjects with suspected FASD (69%) had been adopted.

Conclusions: This study is the most comprehensive review of FASD among Israeli children and adolescents in a population with learning and behavior challenges.
