RESUMEN
OBJECTIVES: L-Thyroxine ingestion is rarely seen in children; here, we report our experience of it. This study describes the clinical characteristics and laboratory findings of acute L-thyroxine ingestion in children. METHODS: This retrospective study enrolled patients treated for L-thyroxine ingestion at Kayseri Teaching Hospital between September 2013 and September 2016. Clinical characteristics and laboratory findings are described. Ethical approval was not obtained because the study was retrospective. RESULTS: The incidence of L-thyroxine ingestion was 0.07% to 1.2% per year. There were 14 patients. Twelve patients were asymptomatic, but 2 (14.2%) exhibited tachycardia and hypertension. Thyroid hormone levels were elevated in 3 patients (21.4%). Eleven patients did not require medical treatment (78.4%); 3 did. No serious complication or death was observed. CONCLUSIONS: Acute ingestion has a benign course. Serious complications are uncommon but may appear several hours or days after ingestion; therefore, patients with L-thyroxine ingestion should be followed closely for 2 weeks.

The effectiveness of using a face mask with a small diffuser for oxygen delivery (OxyMask) was compared to use of a high-flow nasal cannula (HFNC) in patients with moderate or severe bronchiolitis.The study population in this open, phase 4, randomized controlled trial consisted of 60 patients aged 1-24 months diagnosed with moderate or severe bronchiolitis and admitted to an intensive care unit (ICU) for oxygen therapy. The patients were randomized into two groups according to the method of oxygen delivery: a diffuser mask group and an HFNC group.There were seven failures in the mask group and none in the HFNC group. The survival probability differed significantly between the two treatment methods (p = 0.009).Time to weaning off oxygen therapy was 56 h in the HFNC group and 96 h in the mask group (p < 0.001).Conclusion: HFNC use decreased the treatment failure rate and the duration of both oxygen therapy and ICU treatment compared to the diffuser mask, which implies that an HFNC should be the first choice for treating patients admitted to the ICU with severe bronchiolitis. What is known: ⢠A high-flow nasal cannula (HFNC) does not significantly reduce the time on oxygen compared to standard therapy in children with moderate to severe bronchiolitis. Observational studies show that, since the introduction of HFNC, fewer children with bronchiolitis need intubation. For children with moderate to severe bronchiolitis there is no proof of its benefit. What Is New: ⢠In children with moderate to severe bronchiolitis, HFNC provides faster and more effective improvement than can be achieved with a diffuser mask.

OBJECTIVE: We compared the protective effects of secure Chlorhexidine Gluconate (CHG)-containing dressings with those of non-antimicrobial transparent dressings. METHODS: This prospective, comparative, single-center clinical study was conducted in a tertiary pediatric intensive care unit from October 2014 to March 2017. The inclusion criterion was catheterization of the jugular vein for ≥48 hour. The study was conducted in two phases. Non-antimicrobial standard dressings were applied both before and after the CHG- dressing phase to negate any coincidental temporal effect. During the standard-dressing phases, the dressings did not include any antimicrobial; transparent CHG-impregnated dressings were applied during the test phase. All patients were divided into two groups by the type of dressing applied (standard and CHG-containing dressings). RESULTS: The standard- and CHG-dressing groups contained 68 and 63 patients, respectively. The median durations of catheterization were 13 (8-22) and 14 (2-28) days, respectively (p>0.05). The Catheter-Related Bloodstream Infection (CRBSI) rate was somewhat lower in the CHG-dressing group (20.6 vs. 26.5%), but the difference was not statistically significant (p>0.05). In the CHG-dressing group, CRBSIs caused by Gram-positive microorganisms totaled 0%, but the figure was 8.8% in the control group (p=0.028). CONCLUSIONS: CHG dressings reduced CRBSIs caused by Gram-positive microorganisms.
RESUMEN
Pompe disease (OMIM no 232300) is an autosomal recessive inherited metabolic disorder, caused by glycogen accumulation in the lysosome due to deficiency of the lysosomal acid 03B1-glucosidase enzyme. Here we report the case of an 8-month-old girl of consanguineous Turkish parents, who was diagnosed with the infantile form of Pompe disease. Two different uncommon homozygote mutations (c.32-13 T > G homozygote and c.1856G > A homozygote) were detected. The patient had a more progressive clinical course than expected. We emphasize the rare combination of genetic mutations in this Turkish family with Pompe disease.

Invasive candidiasis is an important cause of morbidity and mortality, which primarily occurs in intensive care units. The Candida colonization index is an accepted score as an early warning tool for invasive candidiasis. This study was performed in a medical PICU with patients prone to contracting invasive candidiasis, to determine the usefulness of the Candida colonization index in forecasting invasive candidiasis in children. This prospective study including 87 patients (children 1 month to 16 years old with several illnesses and requiring ICU care) was conducted in a 22-bed medical PICU, Health Science University of Kayseri Training and Research Hospital, between January 2015 and September 2016. Those patients not on antifungal therapy, who were expected to stay more than seven days in PICU and had no history of a PICU stay within the previous two months were included in the study. In all patients, rectal, cervical, throat, axillary, perineal and nasal swab cultures, urine culture and blood culture tests were performed at admission and every week throughout their stay. Overall, 2639 swab and urine cultures (mean: 30.3) and 325 blood cultures (mean: 3.73) were obtained from 87 patients and a total of 576 grew Candida spp. In patients' swab and urine cultures C. albicans was detected in 64.5%, C. parapsilosis in 12.1%, C. glabrata in 7.5%, Saccharomyces spp in 3.0 %, C. tropicalis in 2.4%, C. krusei in 2.1% and C. kefyr in 1.2%. Three patients had C. albicans and one had C. parapsilosis growth in blood culture. Sensitivity, specificity, positive predictive value and negative predictive value for CI were found to be 33.73%, 100%, 6.7%, and 100%, respectively. Patients are at risk of fungal infection in paediatric intensive care units. Specificity and the negative predictive value of 100 % indicate that CI is a useful score to rule out the presence of invasive fungal disease. On the other hand, the low rate of sensitivity (33.3 %) and positive predictive value (6,7%) make this score less reliable in forecasting invasive candidiasis in children.

AIM: This study aimed to determine inappropriate antibiotic use in a children's hospital using the point-surveillance method. MATERIAL AND METHODS: One hundred thirteen hospitalized patients were included in the study on the study day. In all patients, data regarding age, sex, antibiotic use, type and dose of antibiotic if used, multiple antibiotic use, presence or absence of consultation with infectious diseases specialist before initiation of antibiotic, form of antibiotic use (empiric, targeted or prophylactic), and reason for antibiotic use were recorded. Inappropriate antibiotic use was determined by an infectious diseases specialist. RESULTS: The rate of antibiotic use was 70.8%. Of the patients receiving antibiotics, 43% were using more than one antibiotic. It was found that 73.7% of antibiotics were prescribed for empiric purposes and 14.3% for targeted therapy, whereas 12% were prescribed for prophylactic purposes. The rate of inappropriate antibiotic use was 33.8% among patients who were given antibiotics. Unnecessary antibiotic prescription was the most common cause for inappropriate antibiotic use (51.9%), followed by unnecessary multiple antibiotic use (29.6%), inaccurate dosing (11.1%), use of broader spectrum than required (7.4%), and use of antibiotics with narrower spectrum than needed (3.7%). The rate of inappropriate antibiotic use was significantly lower in antibiotics that required confirmation by an infectious diseases specialist (6.7%) than those not requiring confirmation (26.3%; p=0.023). The rate of inappropriate antibiotic use was significantly lower in antibiotics prescribed by infectious diseases specialists (8.6%) than those prescribed by other physicians (26.5%, p=0.027). CONCLUSION: Antibiotic use based on consultation with an infectious diseases specialist decreased inappropriate antibiotic use.
RESUMEN
OBJECTIVE: The aim of the present study is to determine the presence of iron (Fe) deficiency and Fe deficiency anemia in children with zinc (Zn) deficiency. MATERIALS AND METHODS: This retrospective study comprised 560 patients aged 6 months to 16 years in whom Zn levels in hair samples were measured concurrently with serum levels of ferritin, Fe, Fe-binding capacity, and blood count analysis. For all patients, we retrospectively assessed serum ferritin, serum Fe, Fe-binding capacity, transferrin saturation index, red blood cell count, hemoglobin levels, hematocrit, mean corpuscular volume (MCV), mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, and red cell distribution width (RDW). Patients were divided into two groups according to the level of the hair Zn level as Zn deficiency (hair Zn level <100 µg/g) and without Zn deficiency (hair Zn level >100 µg/g). Data were analyzed to determine whether there was a significant difference between any of these parameters and the presence of Fe deficiency and Fe deficiency anemia between patients with and without Zn deficiency. RESULTS: A total of 238 patients had Zn levels <100 µg/g, and 322 patients had Zn levels >100 µg/g. The median ferritin level was 16.2 (9.8-24.9) ng/mL in the Zn-deficient group and 18.7 (12-29.3) ng/mL in those without Zn deficiency group. The presence of Fe deficiency was higher in the Zn deficiency group (60.1%) than in the without Zn deficiency group (50%; p<0.05). The presence of Fe deficiency anemia was significantly higher in the Zn deficiency group (20.2%) than in the without Zn deficiency group (12.7%; p<0.05). There were very weak negative significant correlation between hair Zn and RDW level (r=-0.24; p<0.001) and weak positive correlation between hair Zn and MCV (r=0.31; p<0.001). CONCLUSION: Fe deficiency and Fe deficiency anemia increased in patients with zinc deficiency.
RESUMEN
Boron plays roles in the metabolism of calcium, vitamin D, steroid hormones, healthy bone development, and maintenance of cell membranes. The biological effects of boron are dose-dependent but follow a U-shaped pattern, rendering it important to define the active range. The studies of Bahadoran et al. on rats and Naghii et al. on humans showed that low doses of boron (3 and 10 mg/day) prevented kidney stone formation. The aim of this study was to determine whether high doses of boron have an anti-urolithiatic or antioxidant effect on nephrolithiasis in an experimental rat model. The study was conducted on 50 adult male Wistar rats randomized to five groups. Nephrolithiasis was induced with water containing 0.75% ethylene glycol (EG) and 2% ammonium chloride (AC). This treatment was given to animals in all groups for 10 days, except the positive and negative controls. Simultaneously, groups 2, 3, and 4 were given boric acid via gavage at doses of 25, 50, and 100 mg/kg/day (equivalent to 4/8/16 mg boron respectively) as the source of boron. Animals in the negative and positive control groups were given 6 µL/g distilled water without boric acid. At day 10, intra-cardiac blood samples were drawn from all animals. The right and left kidneys were removed for biochemical and histopathological examinations, respectively. The groups were compared with respect to serum urea, creatinine, calcium, phosphorous, total antioxidant status (TAS), total oxidant status (TOS), serum paraoxonase (PON1) activity, tissue calcium and oxalate levels, and stone burden as determined by histopathological examination. Serum urea and creatinine levels were significantly higher (p < 0.001 and p < 0.05, respectively), while serum calcium and phosphorous levels were significantly lower (p < 0.001 and p < 0.001, respectively), in animals given EG/AC compared to negative controls. No significant differences were detected in serum calcium, phosphorous, urea, or creatinine levels between animals treated with boron and positive controls (p > 0.05). Serum PON1 activity was significantly lower in animals given EG/AC than in negative controls (p < 0.001), while no significant difference in serum PON1 level was detected between rats treated with boron and positive controls. No significant differences were detected in vitamin D, TAS, TOS, tissue calcium, or tissue oxalate levels among groups. No stone formation was detected on histopathological examination in negative controls. No significant differences were found in stone formation between rats treated with boron and positive controls. Based on this study, high doses of boron had no protective effect against nephrolithiasis and oxidative stress.

AIM: In this study, it was aimed to retrospectively assess the frequency and antibiotic resistance of microorganisms isolated from blood cultures of patients in a pediatric intensive care unit. MATERIAL AND METHODS: The study was conducted on blood culture tests obtained from patients in a pediatric intensive care unit and sent to a microbiology laboratory between 2013 and 2016. The species and antibiotic susceptibilities were assessed in microorganisms isolated from the blood cultures. RESULTS: Overall, 4239 blood cultures were obtained. Growth was detected in 324 blood cultures (7.6%). Of the microorganisms isolated, 195 (60.2%) were Gram-positive bacteria, and 107 (33.0%) were Gram-negative bacteria; 22 (6.8%) were fungi. The most commonly isolated microorganisms were Coagulase-negative staphylococci (45.1%), followed by Klebsiella pneumonia (14.5%), and Enterococcus faecalis (6.5%). Among the fungi, the most common was Candida albicans (59.1%), followed by Candida parapsilosis. The resistance rate against methicillin was 89.9% in coagulase-negative staphylococci, and 66% in S. aureus strains. The resistance rate against vancomycin was 3.6% in Enterococci spp. There was no resistance against linezolid in Gram-positive microorganisms. The rate of extended-spectrum beta lactamase positivity was found as 34% in Klebsiella spp. and 100% in Escherichia coli. The resistance rate against carbapenem was 44.9% in Gram-negative bacteriae. The resistance rate against carbapenem was 100% in Acinetobacter baumanii. In Candida albicans, resistance to amphotericine B was 61.5%, and resistance to voriconazole was 7.7%. CONCLUSIONS: To plan effective empiric antibiotic therapy against nosocomial infections in intensive care units, all units should have information about the characteristics of their own flora.
RESUMEN
Acute necrotizing encephalopathy is characterized by multiple, symmetrical lesions involving the thalamus, brainstem, cerebellum, and white matter and develops secondarily to viral infections. Influenza viruses are the most common etiological agents. Here, we present the first case of acute necrotizing encephalopathy to develop secondarily to human bocavirus. A 3-year-old girl presented with fever and altered mental status. She had had a fever, cough, and rhinorrhea for five days. The patient was admitted to the intensive care unit with an initial diagnosis of encephalitis when vomiting, convulsions, and loss of consciousness developed. Signs of meningeal irritation were detected upon physical examination. There was a mild increase in proteins, but no cells, in the cerebrospinal fluid (CSF). Brain magnetic resonance imaging showed symmetrical, heterogeneous hyperintensities bilaterally in the caudate nuclei and putamen. Ammonium, lactate, tandem mass spectroscopy, and urine organic acid were normal. No bacteria were detected in the CSF cultures. Human bocavirus was detected in a nasopharyngeal aspirate using real-time PCR, while no influenza was detected. Oseltamivir, acyclovir, 3% hypertonic saline solution, and supportive care were used to treat the patient, who was discharged after two weeks. She began to walk and talk after one month of physical therapy and complete recovery was observed after six months. Human bocavirus is a recently identified virus that is mainly reported as a causative agent in respiratory tract infections. Here, we present a case of influenza-like acute necrotizing encephalopathy secondary to human bocavirus infection.

OBJECTIVE: The aim of this study was to identify microorganisms causing ventilator-associated pneumonia (VAP) and also study the antibiotic resistance/susceptibility. MATERIALS AND METHODS: We retrospectively assessed microorganisms isolated from patients diagnosed with VAP in a pediatric intensive care unit between January 1, 2014, and June 30, 2016. RESULTS: We included 44 patients diagnosed with VAP. The prevalence thereof was 8.6 patients per 1,000 ventilator days. Mechanical ventilation was required for 56.5% of patients. Thirty-three patients (75%) died. An underlying chronic disease was detected in 75% of patients (n=33). Fifty microorganisms were isolated from 44 patients. Single microorganisms were isolated from 86.4% (n=38) and two from 13.6% (n=6) of patients. Of all the isolated bacteria, 96% (n=48) were gram-negative; the most common was Pseudomonas aeruginosa (32%), followed by Klebsiella pneumoniae (24%) and Acinetobacter baumannii (22%). The isolates were most susceptible to colistin (92.6%), followed by piperacillin-tazobactam (71.4%), amikacin (65.2%), and gentamicin (52.2%). No enterobacterium or Acinetobacter strain was resistant to colistin; however, 13% of P. aeruginosa isolates were resistant. CONCLUSION: In VAP, it is essential to catalog antibiotic resistance patterns of bacteria present in the unit to ensure that empirical antibiotic therapy is effective.
RESUMEN
AIM: Platelets which are known to play a role in inflamation change their shapes when they are activated and this change is reflected in mean platelet volume and platelet distribution width values. Therefore, the mean platelet volume and platelet distribution width values are considered to be beneficial parameters for the diagnosis and treatment of many inflammatory diseases. The aim of the study was to evaluate platelet volume indices in children with acute bronchiolitis. MATERIAL AND METHODS: A total of 514 infants who were below the age of 2 years old were evaluated in this study. Three hundred thirteen of these infants were diagnosed with acute bronchiolitis patients and 201 were healthy children. The patients were separated into four groups as mild, moderate, severe bronchiolitis and the control patient group. The groups were evaluated in terms of significant differences in the values of mean platelet volume and platelet distribution width. A p value of <0.05 was considered statistically significant for all results. RESULTS: The mean platelet volume was found to be 6.8±0.6 fL in the patients with mild bronchiolitis attack, 6.7±0.6 fL in the patients with moderate bronchiolitis attack, 6.5±0.5 fL in the patients with severe bronchiolitis attack and 7.3±1.1 fL in the control group. The mean platalet volume was statistically significantly lower in the mild, moderate and severe bronchiolitis attack groups compared to the control group (p=0.000). The platelet distribution width was found to be 17.2%±0.83 in the mild bronchiolitis attack group, 17.1%±0.96 in the moderate bronchiolitis attack group, 17.3%±0.87 in the severe bronchiolitis attack group and 16.9±1.6% in the control patient group. This difference was not statistically significant (p=0.159). The platelet count was statistically significantly higher in the mild, moderate and severe bronchiolitis attack groups compared to the control group (p=0.000). CONCLUSIONS: The mean platalet volume is decreased in patients with acute bronchiolitis. It is not a useful criterion in determining the severity of bronchiolitis attack. It is important that clinicians evaluating hemogram results to also interprete this variable.
RESUMEN
Extravasation of vasopressors can have serious complications varying from simple local reactions to skin necrosis and compartment syndrome. Here, we presented bullous dermatitis and skin necrosis which developed due to extravasation of adrenalin infusion in a Hodgkin lymphoma patient with septic shock who was admitted due febrile neutropenia.
RESUMEN
Late presentation of congenital diaphragmatic hernia is 5-30% of all congenital diaphragma hernia cases. It can present as Morgagni, Bochdalek and paraesophageal hernia. Misdiagnosis can result in significant morbiditiy. A 17-month-old girl presented with vomiting and abdominal pain. On physical examination, circulatory disturbance, cyanosis, abdominal distantion were present. Her O2 saturation was 60% and she was tachycardic (180 bpm) and tachypneic (58 bpm) with hypotension (60/35 mmhg). Patient's heart and mediastinum were shifted into the right hemithorax on the chest X-ray. Bowel loops in the left hemithorax with air-fluid levels were seen in her plain X-ray and diaphragmatic hernia was seen in her computed tomography examination. She was referred to our center and operated within an hour. Herniated intestinal loops and stomach were observed from about 2 cm diameter defect of diaphragma were repaired primarily. She was extubated in postoperative 4th day. Late presentation of congenital diaphragmatic hernia may be confused with many situation and is difficult to diagnose without clinical suspicion. Accurate diagnosis and urgent treatment is lifesaving.
