A 4-Year-Old Child with a Giant Cerebral Hydatid Cyst: A Case Report.

Echinococcosis is the most common cestode infection globally caused by the Echinococcus species. The most common organ involvement is the lungs and liver, but other organs can be rarely involved. Here, we present a case with a giant cerebral hydatid cyst. A 4-year-old boy presented with abnormal gait and walking at Marmara University School of Medicine Pendik Training and Research Hospital, Istanbul, Türkiye in September 2022. Cranial magnetic resonance imaging showed a cyst of 13 cm in diameter. The cyst was enucleated successfully with no rupture. Oral albendazole therapy was started. There was no eosinophilia, and the echinococcal indirect hemagglutination test was negative. Ultrasonography detected an anechoic cystic lesion in the liver. He was evaluated for deep-organ involvement; however, no cysts were detected in other organs. The histopathological examination was compatible with a hydatid cyst. Although intracranial hydatid disease in children is rare, it should be considered among the differential diagnoses in patients with neurological symptoms, especially in endemic regions.

Single-Center Experience in Vaccination of Children in Special Risk Groups: A Multidisciplinary Institutional Consensus Protocol.

OBJECTIVE: Despite marked improvements in the accessibility of childhood vaccines, knowledge gaps remain about the vaccination of children in special risk groups (SRG). This study aimed to analyze the clinical data of children vaccinated in SRG in a single-center unit to contribute to the clinical evidence for the specific planning of immunization of children in SRG. The second- ary aim is to present institutional consensus on the vaccination of children in SRG. MATERIALS AND METHODS: This retrospective study was conducted at a single-center pediatric vaccination clinic. Patient charts between 2018 and 2021 were retrospectively reviewed, and clinical and laboratory data were extracted. Serial joint meetings with multiple healthcare pro- fessionals were performed to develop an institutional protocol for vaccination. RESULTS: There were 479 children vaccinated between 2018 and 2021 for reasons such as post- chemotherapy, after hematopoietic stem cell transplantation, before/after solid organ trans- plantation, allergies, and chronic diseases. Of these, 298 (62.2%) children vaccinated in the unit due to a history of food or vaccine allergies were excluded. One hundred eighty-one children were vaccinated at a median age of 11 [7-15] years. Most children were vaccinated after treat- ment for malignancies. Solid tumors were the most frequent malignancy (67%), followed by acute lymphoblastic leukemia (29.0%) and acute myeloid leukemia (4.0%). Institutional vacci- nation protocols for cancer survivors, hematopoietic stem cells, and solid organ recipient chil- dren were developed and presented. CONCLUSION: There is a need to prepare national guidelines for vaccinating children with altered immunocompetence. Sharing vaccination practices by multidisciplinary vaccination units might increase and provide knowledge to develop national policies.

Umbilical cord serum insulin-like growth factor-1 levels of infants of diabetic mothers are correlated with diastolic dysfunction detected by tissue Doppler echocardiography.

Tissue Doppler echocardiography (TDI) is a convenient method to detect cardiac dysfunction in the infants of diabetic mothers (IDMs). Umbilical cord serum insulin-like growth factor-1 (IGF-1) is known to be higher in IDMs. We aimed to determine whether there is a relation between diastolic functions examined by TDI and cord serum IGF-1 levels of IDMs. Cord serum IGF-1 levels of 32 IDMs and 22 healthy infants were measured. The cardiac functions of the infants were evaluated by M-Mode and TDI. For statistical analysis, Mann-Whitney U and Spearman correlation tests were used for continuous variables, and the chi-square test was used for categorical variables. The cord serum IGF-1 levels of the IDMs were higher (p = 0.000). The left ventricle (LV) e', LVa', LV e'/a', and LV Tei index, indicating left ventricular diastolic dysfunction in IDMs, were detected (LV e' p = 0.016; LV a' p = 0.003; LV e'/ a' p = 0.000; LV Tei index p = 0.023). IDMs' cord serum IGF-1 levels were found weakly correlated with the interventricular septum (IVS) and left ventricle posterior wall (LVPW) thicknesses in M-Mode and LV e' and LV e'/a' in TDI (IVS r = 0.357, p = 0.008; LVPW r = 0.289, p = 0.034; LV e' r = 0.297, p = 0.029; LV e'/ a' r = 0.031, p = 0.014). CONCLUSION: To our knowledge, this is the first study to examine the relationship between cord serum IGF-1 levels and diastolic functions of IDMs assessed by TDI. A weak correlation was found between IGF-1 levels and IVS and LVPW thicknesses in M-Mode and LV e' and LV e'/a' parameters in TDI, revealing diastolic dysfunction in IDMs. WHAT IS KNOWN: • The umbilical cord blood serum IGF-1 level of IDMs is higher than in infants of healthy mothers. • Diastolic dysfunction is a well-studied and frequently observed consequence in IDMs. WHAT IS NEW: • This is the first study to examine the relationship between cord serum IGF-1 levels and diastolic functions of IDMs assessed by TDI. • A weak correlation was detected between the median cord serum IGF-1 level of IDMs and the median values of IVS, LVPW, LV e', LV a', LV e'/a' ratio.

The localization of thyroid cancers on the thyroid gland is a new risk factor for metastases of perithyroidal, peritracheal and central lymph nodes.

OBJECTIVE: Lymph node metastasis is frequently detected in differentiated thyroid cancers. Central dissection is performed to the lymph nodes in patients with microscopic metastases in the intraoperative evaluation. Other indications for central dissections are tumor size and cervical lateral lymph node metastasis. We consider that the localization of thyroid cancer in the thyroid lodge may be another risk factor for central lymph node metastasis. For this reason, the purpose of the present study was to investigate the relations between thyroid cancer localization and lymph node metastasis in differentiated thyroid cancer patients who had no preoperative cervical metastases and who underwent total thyroidectomy, and peritracheal, perithyroidal, and central lymph node dissection. METHOD: A total of 213 differentiated thyroid cancer cases followed in our general surgery and endocrinology clinic between September 2016 and May 2020 were evaluated retrospectively. Based on the data in the files, the patients who underwent total thyroidectomy, and central, perithyroidal, and peritracheal lymph node dissection were included in the study. The patients were divided into four Groups according to tumor localizations, those with tumors adjacent to the trachea (Group 1), upper thyroid pole (Group 2), thyroid middle part (Group 3), thyroid inferior (Group 4). The demographic characteristics, laboratory parameters, cancer types, and lymph node metastasis rates of the Groups were evaluated. RESULTS: A total of 84% (179) of the cases had thyroid papillary cancer, 11.73% (25) had thyroid follicular cancer, and 4.2% (9) had poorly differentiated thyroid cancer. The mean age of all patients was found to be 49 ± 8.3 years, and the female/male ratio was 2.4. It was found that the differentiated thyroid cancers metastasized to the perithyroidal, peritracheal, and central lymph nodes at a rate of 57.74%. The distribution of these metastases according to the Groups was; 62.85% in Group 1, 11.53% in Group 2, 43.9% in Group 3, and 88.57% in Group 4. It was also found that 80.32% of the papillary cancer cases and 57.14% of the follicular cancer cases metastasized to central (level VI) lymph nodes in Group 4. CONCLUSION: The localization of differentiated thyroid cancers is a new risk factor for perithyroidal metastases.

COVID-19 disease characteristics in different pediatric age groups.

INTRODUCTION: Little is known about the COVID-19 disease characteristics and differences between different pediatric age groups. This study aimed to investigate the disease characteristics according to age groups. METHODOLOGY: We conducted a retrospective, single-center study of pediatric COVID-19 in a tertiary care hospital in Turkey. The patients were divided into three groups: 15 days-24 months old (Group 1), 25-144 months old (Group 2), and 145-210 months old (Group 3) according to age. RESULTS: A total of 139 pediatric patients with COVID-19 were examined. Twenty-nine patients (20.9%) were in Group 1, 52 (37.4%) were in Group 2, 58 (41.7%) were in Group 3. Thirty-nine patients (28.1%) were hospitalized. The most common symptoms were cough (55.4%) and fever (51.8%). The median chest X-ray (CXR) score of hospitalized patients was 1 (min 0-max 7), and the median CXR score of outpatients was 1 (min 0-max 6). Fever was significantly more frequent in Group 1, and chest pain was more frequent in Group 3. Group 1 had significantly higher WBC, lymphocyte, thrombocyte counts, AST, LDH, D-dimer, and Troponin T levels but lower hemoglobin, total protein, and albumin levels. The treatment included antibiotics, oseltamivir, hydroxychloroquine, and supportive therapy. Only one patient (0.7%) received non-invasive mechanical ventilatory support. CONCLUSIONS: As we know the clinical course of COVID-19 in children is less severe than in adults. We also found significant differences in both clinical and laboratory findings between different pediatric age groups which supports the theory that disease pathogenesis is highly variable according to age.

Multisystem inflammatory syndrome in children associated with COVID-19 in 101 cases from Turkey (Turk-MISC study).

AIM: Multisystem inflammatory syndrome in children (MIS-C) may cause shock and even death in children. The aim of this study is to describe the clinical features, laboratory characteristics and outcome of children diagnosed with MIS-C in 25 different hospitals in Turkey. METHODS: The retrospective study was conducted between 8 April and 28 October 2020 in 25 different hospitals from 17 cities. Data were collected from patients' medical records using a standardised form. Clinical and laboratory characteristics and outcomes according to different age groups, gender and body mass index percentiles were compared using multivariate logistic regression analysis. RESULTS: The study comprised 101 patients, median age 7 years (interquartile range (IQR) 4.6-9.3); 51 (50.5%) were boys. Reverse-transcriptase polymerase chain reaction (PCR) assay was positive in 21/100 (21%) patients; 62/83 (74.6%) patients had positive serology for SARS-CoV-2. The predominant complaints were fever (100%), fatigue (n = 90, 89.1%), and gastrointestinal symptoms (n = 81, 80.2%). Serum C-reactive protein (in 101 patients, median 165 mg/L; range 112-228), erythrocyte sedimentation rate (73/84, median 53 mm/s; IQR 30-84) and procalcitonin levels (86/89, median 5 µg/L; IQR 0.58-20.2) were elevated. Thirty-eight patients (37.6%) required admission to intensive care. Kawasaki disease (KD) was diagnosed in 70 (69.3%) patients, 40 of whom had classical KD. Most patients were treated with intravenous immunoglobulin (n = 92, 91%) and glucocorticoids (n = 59, 58.4%). Seven patients (6.9%) died. CONCLUSION: The clinical spectrum of MIS-C is broad, but clinicians should consider MIS-C in the differential diagnosis when persistent fever, fatigue and gastrointestinal symptoms are prominent. Most patients diagnosed with MIS-C were previously healthy. Immunomodulatory treatment and supportive intensive care are important in the management of cases with MIS-C. Glucocorticoids and intravenous immunoglobulins are the most common immunomodulatory treatment options for MIS-C. Prompt diagnosis and prompt treatment are essential for optimal management.

Successful Treatment of Fasciola hepatica with Metronidazole in a Child: A Case Report.

Fasciola hepatica is a zoonotic liver trematode that usually causes infection in cattle and sheep, and is transmitted to humans by consuming water and aquatic plants contaminated with metacercaria. The detection of Fasciola eggs in stools, serological evaluation and radiological evaluation are essential for diagnosis. Triclabendazole is the first-line therapy for fascioliasis. However, as triclabendazole is not an easily accessible drug in countries such as Turkey, it reveals a quest for alternative therapies. In this report, we present a 10-year-old boy with fascioliasis successfully treated with a course of metronidazole 1.5 g/day for 3 weeks in 2020. During the follow-up, eosinophilia and radiological findings completely recovered. Here we report a case of pediatric fascioliasis that was cured with metronidazole successfully.

Incidence of multisystem inflammatory syndrome in children and the comorbidity scores in pediatric coronavirus disease 2019 cases.

BACKGROUND: We aimed to determine the incidence of multisystem inflammatory syndrome in children (MIS-C) in pediatric coronavirus disease 2019 (COVID-19) cases and to define the relationships between the need for hospitalization, the development of MIS-C, and the Charlson Comorbidity Index (CCI) and Pediatric Comorbidity Index (PCI) scores. METHODS: All pediatric COVID-19 cases between March 25, 2020, and December 28, 2020, in the Marmara University Pendik Training and Research Hospital were enrolled. Patients who needed hospitalization were determined. Hospital records were re-examined to identify those diagnosed as having MIS-C. The CCI and PCI were used to validate the comorbidity status. RESULTS: Among 2,055 pediatric COVID-19 cases, 1,340 were included in the study, and 213 patients (15.9%) had at least one comorbidity. All the patients or their parents were interviewed about the need for hospitalization, except for the acute period. Six patients had MIS-C, which corresponds to a MIS-C incidence of 0.4%. The need for hospitalization increased in the patients with comorbidities (P < 0.05). No correlation was found between the comorbidity scores and the development of MIS-C. The need for hospitalization increased in the patients with CCI scores of ≥2 and PCI scores of ≥4 (P < 0.05). CONCLUSIONS: Our study is the first to examine the incidence of MIS-C, which was 0.4%, by long-term follow up of pediatric COVID-19 cases and to demonstrate that the CCI and PCI can be used to predict the need for hospitalization and prognosis of pediatric patients with COVID-19.

Cancers Detected During the Evaluation Before Bariatric Surgery in Obese Patients: a High-Risk Population for Cancers and Their Prevalence.

PURPOSE: The purpose of the present study was to determine the types and prevalence of cancers in obese patients who have risks for cancer with multidisciplinary evaluation in managing the patients before bariatric surgery. MATERIALS AND METHODS: The study had a descriptive cross-sectional method conducted by examining patients' files retrospectively. The frequency and types of diseases with cancer during the multidisciplinary evaluation of the study group with a BMI ≥ 40 kg/m2 before bariatric surgery were used as the study data. RESULTS: A total of 1354 (64.97%) of these patients underwent bariatric surgery (for obesity), and 730 (35.02%) cases underwent metabolic surgery (type 2 diabetic patients). Eighteen patients had thyroid papillary cancer (0.86%) and colon cancer was detected in 8 people (0.38%), breast cancer in 6 people (0.47%), stomach cancer in 5 people (0.23%), kidney cancer in 3 people (0.1%) 4), lung cancer in 2 people (0.09%), pancreatic cancer in 2 people (0.09%), adrenal cancer in 2 people (0.09%), and neuroendocrine tumor in 1 person (0.04%). CONCLUSION: It was found that obesity and some cancers are related. Weight loss to be achieved with obesity surgery can reduce the risk of obesity-related cancers.

C-reactive protein and neutrophil-lymphocyte ratio as predictors of mortality in coronavirus disease 2019

SUMMARY OBJECTIVE: This study investigates whether C-reactive protein, platelet-lymphocyte ratio, and neutrophil-lymphocyte ratio could be useful to predict mortality in COVID-19. METHODS: Data of 635 patients with COVID-19 followed up in Sinop Ataturk State Hospital from February to May 2020 were evaluated retrospectively. Diagnosis of COVID-19 was made according to the interim guidance of the World Health Organization. Patients were grouped into two groups based on mortality as survived and non-survived patients. Age, gender, neutrophil-lymphocyte ratio, platelet-lymphocyte ratio, and C-reactive protein of the groups were investigated and compared. RESULTS: The mean age of the participants was 55.8±22.3 years. Among the patients, 584 survived and 51 patients died. Age was significantly different between the groups, 54.2±22.3 in the survived group and 75.6±11.1 in the dead group (p=0.000). In addition, neutrophil, C-reactive protein, and neutrophil-lymphocyte ratio values were significantly higher in the dead group (p=0.000). platelet-lymphocyte ratio was slightly higher in the dead group, but this difference was not significant (p=0.42). The area under the curve values for age, lymphocyte, platelet, C-reactive protein, and neutrophil-lymphocyte ratio are 0.797, 0.424, 0.485, 0.778, and 0.729, respectively. CONCLUSIONS: Our results showed that neutrophil-lymphocyte ratio and C-reactive protein are significantly higher in patients leading to death and could be effective biomarkers in predicting COVID-19 fatality. Furthermore, C-reactive protein could be used as an independent biomarker to predict death in patients with COVID-19, regardless of gender and age (p=0.000).

How safe are children with COVID-19 from cardiac risks? Pediatric risk assesment; insights from echocardiography and electrocardiography

Background/aim: Approximately 40 million individuals worldwide have been infected with SARS-CoV-2, the virus responsible for the novel coronavirus disease-2019 (COVID-19). Despite the current literature about the cardiac effects of COVID-19 in children, more information is required. We aimed to determine both cardiovascular and arrhythmia assessment via electrocardiographic and echocardiographic parameters. Materials and methods: We evaluated seventy children who were hospitalized with COVID-19 infections and seventy children as normal control group through laboratory findings, electrocardiography (ECG), and transthoracic echocardiography (TTE). Results: We observed significantly increased levels of Tp-Te, Tp-Te/QT, and Tp-Te/QTc compared with the control group. Twenty-five of 70 (35.7%) patients had fragmented QRS (fQRS) without increased troponin levels. On the other hand, none of the patients had pathologic corrected QT(QTc) prolongation during the illness or its treatment. On TTE, 20 patients had mild mitral insufficiency, among whom only five had systolic dysfunction (ejection fraction < 55%). There was no significant difference between the patient and control groups, except for isovolumic relaxation time (IVRT) in terms of mean systolic and diastolic function parameters. IVRT of COVID patients was significantly lower than that of control group. Conclusion: Despite all the adult studies, the effects of COVID­19 on myocardial function are not well established in children. The thought that children are less affected by the illness may be a misconception.

Delayed diagnosed Gradenigo's syndrome associated with acute otitis media.

Gradenigo's syndrome presents as a triad of retroorbital pain, ipsilateral abducens palsy, and purulent otorrhea. If the otologic pathologies in Gradenigo's syndrome go unnoticed, the condition could be misdiagnosed with neurological diseases because of retroorbital pain and abducens palsy. Treatment of Gradenigo's syndrome remains controversial. Although some reports state that long-term antibiotic treatment is sufficient, we recommended that management ought to be guided on a case-by-case basis depending on patient and disease factors. Herein, we report a delayed diagnosed pediatric case of Gradenigo's syndrome associated with acute otitis media that was treated with ventilation tube insertion.
