Clinical features of peritonsillar abscess in children.

BACKGROUND Peritonsillar abscess is an acute infection located between the capsule of the palatine tonsil and the superior constrictor muscle of the pharynx. The reports regarding pediatric cases have been scanty. METHODS A retrospective study was conducted to investigate the patients less than 18 years of age hospitalized at a medical center with a final diagnosis of peritonsillar abscess from January 1999 through December 2009. Only those who were confirmed by the drainage of pus from the peritonsillar spaces or confirmed by a computed tomography (CT) scan were enrolled. RESULTS In total, 56 children, 31 male and 25 female, were included. The mean age was 12.9 ± 4.6 years, ranging from 9 months to 17.9 years. Nineteen (34%) were less than 12 years of age. All 37 children ≧12 years of age complained of sore throat, but only 68% of children less than 12 years of age complained of sore throat. Thirty-one patients (55%) with a characteristic presentation of fever and sore throat plus an asymmetric swollen/bulging tonsil with or without uvular deviation suggestive of the diagnosis received surgical drainage at emergency department immediately, and 87% of them were older than 12 years of age. Twenty-five (45%) children needed a CT scan to confirm the diagnosis. The most common empirical antibiotics were penicillin-containing regimens. The predominant organisms identified were Streptococcus species. Eight children were treated successfully with antibiotics alone. No case was fatal. CONCLUSION Two-thirds of the children with peritonsillar abscess were ≥12 years of age. Not every patient <12 years of age had a characteristic presentation, and a CT scan was usually needed to confirm the diagnosis.

Clinical Presentation of Pediatric Myocarditis in Taiwan

BACKGROUND The purposes of this study were to characterize the symptoms and signs of children with myocarditis at the time of presentation to the hospital and to identify the predictors of death. METHODS This was a 5-year retrospective study in a tertiary hospital. We collected demographic data and clinical symptoms and signs when children with myocarditis presented at the hospital. The outcome for patient was classified as either survival or death, and the predictors of death were identified. RESULTS Over the 5-year period, 27 children (14 boys and 13 girls) met the definition of clinical myocarditis. The mean age of the myocarditis patients was 9.1±5.1 years (range, 0.08-17.9 years), and the maximum age was 10-12 years. The most common presentation was gastrointestinal symptoms. We used extracorporeal membrane oxygenation on nine (33%) children, and pacemaker was implanted in eight (30%). Six (22%) children died in this study, and only one of them was younger than 6 years. The poor prognosis predictors were gastrointestinal symptoms, hepatomegaly, and hypotension. CONCLUSIONS Pediatric myocarditis presents primarily with gastrointestinal symptoms in Taiwan. Careful check of heart rhythm may provide a useful objective marker of myocarditis. The predictors of a poor prognosis were gastrointestinal symptoms, hepatomegaly, and hypotension.

Decreased ADAMTS 13 Activity is Associated With Disease Severity and Outcome in Pediatric Severe Sepsis.

AbstractDecreased ADAMTS 13 activity has been reported in severe sepsis and in sepsis-induced disseminated intravascular coagulation. This study aimed to investigate the role of ADAMTS 13 in different pediatric sepsis syndromes and evaluate its relationship with disease severity and outcome.We prospectively collected cases of sepsis treated in a pediatric intensive care unit, between July 2012 and June 2014 in Chang Gung Childrens Hospital in Taoyuan, Taiwan. Clinical characteristics and ADAMTS-13 activity were analyzed.All sepsis syndromes had decreased ADAMTS 13 activity on days 1 and 3 of admission compared to healthy controls. Patients with septic shock had significantly decreased ADAMTS 13 activity on days 1 and 3 compared to those with sepsis and severe sepsis. There was a significant negative correlation between ADAMTS 13 activity on day 1 and day 1 PRISM-II, PELOD, P-MOD, and DIC scores. Patients with mortality had significantly decreased ADAMTS 13 activity on day 1 than survivors, but not on day 3.Different pediatric sepsis syndromes have varying degrees of decreased ADAMTS 13 activity. ADAMTS 13 activity is strongly negatively correlated with disease severity of pediatric sepsis syndrome, whereas decreased ADAMTS 13 activity on day 1 is associated with increased risk of mortality.

Therapeutic burst-suppression coma in pediatric febrile refractory status epilepticus

BACKGROUND Evidence for the beneficial effect of therapeutic burst-suppression coma in pediatric patients with febrile refractory status epilepticus is limited, and the clinical outcomes of this treatment strategy are largely unknown. Therefore, the aim of this study was to explore the outcomes of therapeutic burst-suppression coma in a series of children with febrile refractory status epilepticus. METHODS We retrospectively reviewed consecutive pediatric patients with febrile refractory status epilepticus admitted to our pediatric intensive care unit between January 2000 and December 2013. The clinical characteristics were analyzed. RESULTS Thirty-five patients (23 boys; age range: 1-18years) were enrolled, of whom 28 (80%) developed super-refractory status epilepticus. All of the patients received the continuous administration of intravenous antiepileptic drugs for febrile refractory status epilepticus, and 26 (74.3%) achieved therapeutic burst-suppression coma. All of the patients received mechanical ventilatory support, and 26 (74.3%) received inotropic agents. Eight (22.9%) patients died within 1month. The neurologically functional outcomes at 6months were good in six (27.3%) of the 22 survivors, of whom two returned to clinical baseline. The patients with therapeutic burst-suppression coma were significantly associated with hemodynamic support than the patients with electrographic seizures control (p=0.03), and had a trend of higher 1-month mortality rate, worse 6months outcomes, and a longer duration of hospitalization. CONCLUSIONS Our results suggest that therapeutic burst-suppression coma to treat febrile refractory status epilepticus may lead to an increased risk of hemodynamic instability and a trend of worse outcomes.

An unusual cause of pediatric altered mental status: a mesenteric hernia.

Altered mental status can have many causes, some of which are life threatening, especially in children. In addition to the usual central nervous system and metabolic causes, such as meningitis, encephalitis, seizure, electrolyte imbalance, and inborn errors of metabolism, some less common causes of altered mental status, which if not diagnosed and managed rapidly, can have poor consequences. We present a case of a child with a life-threatening unusual cause of altered mental status, a mesenteric hernia with hypovolemic shock. The hernia was reduced successfully at laparotomy. The postoperative course was uneventful.

Increased serum thrombomodulin level is associated with disease severity and mortality in pediatric sepsis

Background Endothelial dysfunction plays an important role in the pathophysiology of sepsis. As previously reported, the serum thrombomodulin is elevated in diseases associated with endothelial injury. Objective The aim of this study was to investigate the association of serum thrombomodulin level in different pediatric sepsis syndromes and evaluate the relationship with disease severity and mortality. Methods We prospectively collected cases of sepsis treated in a pediatric intensive care unit from June 2012 to July 2015 at Chang Gung Children’s Hospital in Taoyuan, Taiwan. Clinical characteristics and serum thrombomodulin levels were analyzed. Results Increased serum thrombomodulin levels on days 1 and 3 of the diagnosis of sepsis were found in different pediatric sepsis syndromes. Patients with septic shock had significantly increased serum thrombomodulin levels on days 1 and 3 [day 1: median, 6.9 mU/ml (interquartile range (IQR): 5.8–12.8) and day 3: median, 5.8 mU/ml (IQR: 4.6–10.8)] compared to healthy controls [median, 3.4 mU/ml (IQR: 2.3–4.2)] (p = <0.001 and 0.001, respectively) and those with sepsis [day 1: median, 2.9 mU/ml (IQR: 1.8–4.7) and day 3: median, 3 mU/ml (IQR: 1.5–3.5)] and severe sepsis [day 1: median, 3.3 mU/ml (IQR: 1.3–8.6) and day 3: median, 4.4 mU/ml (IQR: 0.5–6)] (p = <0.001 and 0.001, respectively). There was also a significant positive correlation between serum thrombomodulin level on day 1 and day 1 PRISM-II, PELOD, P-MOD and DIC scores. The patients who died had significantly higher serum thrombomodulin levels on days 1 and 3 [day 1: median, 9.9 mU/ml (IQR: 6.2–15.6) and day 3: median, 10.4 mU/ml (IQR: 9.2–11.7)] than the survivors [day 1; median, 4.4 mU/ml (IQR: 2.2–7.5) and day 3: [median, 3.5 mU/ml (IQR: 1.6–5.7)] (p = 0.046 and 0.012, respectively). Conclusion Increased serum thrombomodulin levels were found in different pediatric sepsis syndromes and correlated with disease severity and mortality.

An unusual cause of headache and hypertension

Children with both headache and hypertension present a relatively rare condition with a broad range of differential diagnoses in pediatric emergency medicine. Some possible diagnoses are potentially life-threatening conditions and merit aggressive evaluation management. We report a case of a 14-year-old girl who presented with headache and hypertension. She responded poorly to medical treatment and subsequently developed anxiety and difficulties with concentration. Three months later, she visited our ophthalmology department because of blurred vision. Ophthalmic evaluation revealed bilateral Kayser-Fleischer rings. Finally, she was diagnosed with Wilson disease. This case emphasizes that children with headache and hypertension merit aggressive evaluation and management.
