Invasive pulmonary and central nervous system aspergillosis after near-drowning of a child: case report and review of the literature

Invasive aspergillosis is extremely rare in immunocompetent children. Here we describe the clinical, radiologic, and laboratory course of fatal invasive pulmonary and central nervous system aspergillosis in a previously healthy child after a near-drowning incident with submersion in a pond. Findings were compared with data from the literature, which is reviewed. Serum Aspergillus galactomannan levels were determined retrospectively and were compared with the results of routine microbiological and radiologic examinations, showing a significant diagnostic and therapeutic delay of the routine diagnostic approach in comparison with the use of the Aspergillus galactomannan assay. This delay may have contributed to the fatal course. Serial determination of serum Aspergillus galactomannan may be helpful in diagnosing invasive aspergillosis early in case of pulmonary disease after near-drowning and may contribute to an early appropriate treatment. Currently voriconazole, eventually in combination with caspofungin, should be considered as the drug of choice in the management of invasive aspergillosis after near-drowning.     

Hemodynamic support of a 15-year-old waiting for a heart transplant: Is there a role for levosimendan in pediatric heart failure?

Decompensated heart failure in children requires rapid and aggressive support. In refractory cases, invasive supportive care is essential to ensure cardiac output. This results in lengthy pediatric intensive care unit (PICU) stays, secondary morbidity, and high cost. Levosimendan may help palliate the pitfalls encountered with the usual treatment. It has been shown to improve hemodynamics and decrease morbidity and mortality from heart failure in adult trials and pediatric cohorts. We report the case of a 15-year-old boy with dilated cardiomyopathy and refractory ventricular dysfunction who was weaned from continuous inotropes and discharged from the PICU with levosimendan while waiting for heart transplantation.     

Aggressive management of dengue shock syndrome may decrease mortality rate: a suggested protocol.

OBJECTIVES: Dengue shock syndrome is a leading cause of mortality among Indian children. In January 2000, we instituted a protocol for aggressive management of children with dengue shock syndrome. The objective of this study was to compare outcomes (duration of ventilation, pediatric intensive care unit stay, incidence of acute respiratory distress syndrome, and intensive care unit and hospital mortality) before and after the protocol. DESIGN: Retrospective chart review. SETTING: Pediatric intensive care unit at a tertiary teaching hospital. PATIENTS: One hundred and fourteen patients admitted between July 1997 and December 1999 received standard therapy recommended by the World Health Organization (WHO) and were designated as the WHO guidelines group (W), whereas 96 patients admitted between January 2000 and December 2001 were treated by our protocol and designated as the protocol group (P). INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The patients in each group were equally matched in terms of age, Pediatric Risk of Mortality, and number with dengue hemorrhage fever grade IV, although the platelet counts were higher in the W group compared with the P group (geometric mean 42.2, confidence interval 36.9, 48.4 vs. geometric mean 36.7, confidence interval 33.3, 40.5, p < .05). Patients in the W group received less fluids in the first hour compared with the P group (median and interquartile range 20 mL/kg, 15 and 20 vs. 30 mL/kg, 20 and 60). Fluid was actively removed less often in the W group than the P group (6 of 111 vs. 45 of 96, p < .05). There was no difference in the need for ventilation or incidence of acute respiratory distress syndrome between groups, although among dengue hemorrhage fever grade IV patients, the number requiring ventilation (17 of 30 vs. 20 of 23, p < .05) and the incidence of acute respiratory distress syndrome (9 of 30 vs. 17 of 23, p < .05) were significantly greater in the W group compared with the P group. The duration of ventilation (1.5 +/- 1.7 vs. 4.2 +/- 2.9 days, p < .05) and length of intensive care unit stay (3.0 +/- 2.8 vs. 3.4 +/- 2.9 days, p < .05) were significantly less in the W group. The pediatric intensive care unit mortality (16.6% vs. 6.3%, p < .05) was significantly higher in the W group than in the P group. CONCLUSIONS: Patients with dengue shock syndrome are at high risk of mortality due to refractory shock and multiple organ failure. Survival was better for patients in the P group. Aggressive shock management and possibly the use of judicious fluid removal may decrease mortality rates in the severest forms of dengue shock syndrome.     

Fulminant liver failure in a child with invasive group A streptococcal infection

Liver involvement is mentioned in streptococcal toxic shock syndrome, but never as fulminant liver failure (FLF). We report the case of a 2-year-old child who developed isolated FLF secondary to invasive group A streptococcal infection without shock due to a M1T1-type strain expressing speA, speB and speC toxin genes. On antibiotics, he recovered rapidly without liver transplantation. CONCLUSION: A streptococcal pyrogenic exotoxin likely constituted the initial insult leading to FLF. This etiology can be included in the differential diagnosis of FLF and would support early introduction of antibiotics.     

The use of recombinant factor VIIa in a patient with Noonan syndrome and life-threatening bleeding.

OBJECTIVE: To present a case report of a patient with Noonan syndrome who developed life-threatening gastrointestinal bleeding shortly after cardiac surgery that was successfully treated with recombinant factor VIIa. DESIGN: Case report. SETTING: Pediatric intensive care unit of a children's hospital. PATIENT: Ten-month-old with Noonan syndrome and massive gastrointestinal bleeding resulting in severe hypovolemic shock. INTERVENTIONS: Recombinant factor VIIa was used in this patient's severe bleeding associated with Noonan syndrome after no other supportive measures were successful. MEASUREMENTS AND MAIN RESULTS: Recombinant Factor VIIa significantly decreased the patient's bleeding and allowed his hypovolemic shock to improve. Ultimately, the patient made a complete recovery. CONCLUSIONS: Noonan syndrome has a constellation of both cardiac and noncardiac malformations including an increased risk of bleeding, and recombinant factor VIIa is an important agent in the treatment of significant bleeding.     

The challenges of prompt identification and resuscitation in children with acute fulminant myocarditis: case series and review of the literature

Aim: To describe the clinical presentation, triage, resuscitation and outcome of acute fulminant myocarditis in children presenting to district hospitals and referred for cardiac intensive care. Methods: Case series describing five patients (from 2 weeks to 12 years old) with a diagnosis of acute fulminant myocarditis, presented to outlying hospitals between December 2006 and December 2007 and retrieved to a cardiac intensive care unit. Results: All children were admitted with non‐specific symptoms such as vomiting, cough and poor feeding to their local hospital, where various provisional diagnoses such as viral gastroenteritis, bronchitis or renal failure were considered. Acute physiological deterioration usually prompted the referral for intensive care. Two children died at the referring hospital during stabilisation by the retrieval team. Three children survived transport to intensive care and to hospital discharge; two received mechanical support and one underwent urgent orthotopic heart transplantation. Enterovirus and parvovirus were identified as causative agents in two patients. In one case, macrophage activation syndrome was diagnosed although no clear viral trigger was identified. Median length of hospitalisation among survivors was 33 days, and mechanical cardiac support was required for a median of 12 days. Conclusions: The diagnosis and initial management of acute fulminant myocarditis is extremely challenging. Prognosis for patients admitted to a cardiac centre for early mechanical support can be very favourable, while a delay in considering the diagnosis may result in poor outcome. The diagnosis of myocarditis should be considered in any previously well child presenting with a viral prodrome and non‐specific organ dysfunction associated with dysrhythmias, shock or acute heart failure, even in the absence of cardiomegaly.     

Systemic capillary leak syndrome presenting as recurrent shock.

OBJECTIVE: To report a case of systemic capillary leak syndrome (SCLS) in a child. DESIGN: Case report. SETTING: Pediatric intensive care unit. PATIENT: A 6-yr-old girl was admitted twice to the pediatric intensive care unit, at a 10-month interval, in severe shock with important edema. RESULTS: The patient presented with acute symptoms of abdominal pain, vomiting, and syncope in the hour preceding the shock. During both episodes necessary management included aggressive intravenous fluid rehydration, mechanical ventilation, and use of inotropes/vasopressors. Suspicion of a lower limb fasciitis necessitated surgical exploration, but pathology reports were negative on both occasions revealing only subcutaneous tissue edema. The patient recovered within 24 hrs on both episodes. Investigation ruled out cardiogenic shock and septic shock due to bacterial etiology. On the first episode, a nasopharyngeal aspirate was positive for influenza A (H3N2) by both viral immunofluorescence and culture. The presumed diagnosis was toxic shock syndrome associated with influenza virus. On the second episode, all bacterial and virology cultures remained negative. Hypovolemic shock was suspected, but there was no history of dehydration, bleeding, or gastrointestinal losses (persistent vomiting or diarrhea). Noninfectious causes of hypovolemic shock with edema were ruled out, leading us to believe that she suffered from SCLS. CONCLUSIONS: Although well described in the adult literature, there have been few reports of SCLS in pediatric patients. SCLS should be considered in the differential diagnosis of recurrent hypovolemic shock without identifiable cause. The only therapeutic intervention is to obtain vascular access when initial manifestations occur and give aggressive fluid reanimation.     

Heart for bonding: a new protocol of care for hypoplastic left heart syndrome

There are significant challenges involved in the perinatal and postnatal care of an infant with hypoplastic left heart syndrome (HLHS) and the infant's family. In the blink of an eye, the perfect child is lost, and a fragile infant is about to join the family. This case study and discussion is an overview of HLHS , a family's desire to make the birth of their infant normal, and how that desire initiated a change in philosophy and practice in our neonatal intensive care unit.     

Complete eradication of Aspergillus fumigatus from the lung in an immunocompromised patient by oral itraconazole

Abstract Itraconazole is a new orally active antifungal agent shown to have in vitro and experimental activity against Aspergillus spp. This case report documents the successful eradication of biopsy-proven invasive pulmonary aspergillosis in a 17 year old boy with acute lymphocytic leukaemia. Cerebral involvement by the fungal infection was suspected clinically but was not biopsy proven. Although the patient subsequently died following bone marrow transplant and Escherichia coli septicaemia there was no evidence of residual Aspergillus at autopsy.     

Persistent thrombocytopenia following dengue shock syndrome

Though thrombocytopenia is one of the hallmarks of dengue hemorrhagic fever/ dengue shock syndrome, persistence of the same is rare. We report an 11 year-old child with dengue shock syndrome, who developed persistent thrombocytopenia. The possible mechanisms are discussed.     

Management of abdominal compartment syndrome during extracorporeal life support.

OBJECTIVE: To describe the successful use of a peritoneal dialysis catheter for emergent decompression of abdominal compartment syndrome during extracorporeal life support for septic shock. DESIGN: Case report. SETTING: Pediatric intensive care unit at a freestanding tertiary children's hospital. PATIENT: Two-year-old toddler with influenza A complicated by methicillin-resistant Staphylococcus aureus pneumonia and septic shock. INTERVENTIONS: Placement of peritoneal dialysis catheter. MEASUREMENTS AND MAIN RESULTS: Changes in hemodynamic and respiratory parameters. Improvement in extracorporeal membrane oxygenation venous drainage with subsequent survival. CONCLUSIONS: Although the standard therapy for abdominal compartment syndrome is decompressive laparotomy, a minimally invasive percutaneous approach may be effective and should be considered in selected patients.     

A new challenge in pediatric obesity: pediatric hyperglycemic hyperosmolar syndrome.

OBJECTIVES: To describe four adolescents with hyperglycemic hyperosmolar syndrome, an uncommon presentation of type 2 diabetes in pediatric patients. DESIGN: Case report. SETTING: Two tertiary pediatric intensive care units in university teaching hospitals. PATIENTS: Four obese adolescents with hyperglycemic hyperosmolar syndrome associated with type 2 diabetes mellitus. INTERVENTIONS: Isotonic fluid resuscitation and insulin. MEASUREMENTS AND MAIN RESULTS: Two of the four patients died. The first patient died within the first 24 hrs of hyperglycemic hyperosmolar syndrome presumably due to hypovolemic shock. The second patient, who died, developed rhabdomyolysis and multiple-system organ failure after a prolonged intensive care unit stay. The third and fourth patients were discharged from the hospital in good health. None of the patients had cerebral edema on head computed tomography, despite differences in fluid and insulin management. CONCLUSIONS: Pediatric patients with hyperglycemic hyperosmolar syndrome have a high mortality rate and may experience multiple complications such as rhabdomyolysis and hypovolemic shock. Treatment strategies to reduce mortality are unclear and warrant further investigation.     

Sinopulmonary aspergillosis in children with hematological malignancy

Invasive pulmonary aspergillosis is a serious infectious complication in immunocompromised especially neutropenic patients. Despite improvements in early diagnosis and effective treatment, invasive pulmonary aspergillosis is still a devastating opportunistic infection. These infections also interfere with the anticancer treatment. We report our experience in the diagnosis and therapeutic management of sinopulmonary aspergillosis in 4 children with hematologic malignancy. All patients except the first were neutropenic when sinopulmonary aspergillosis was diagnosed. Clinical signs included fever, cough, respiratory distress, swallowing difficulty, headache, facial pain-edema and hard palate necrosis. Radiodiagnostic methods showed bilateral multiple nodular infiltrations, soft tissue densities filling all the paranasal sinuses, and bronchiectasis. Diagnosis of aspergillosis was established by bronchoalveolar lavage in one case, tissue biopsy, positive sputum and positive cytology, respectively, in the other 3 cases. One patient was treated with liposomal amphotericin B and other 3 cases were treated with liposomal amphotericin B + itraconozole. Outcome was favorable in all cases except the one who died due to respiratory failure. Early diagnosis, appropriate treatment and primary disease status are important factors on prognosis of Aspergillus infections in children with hematological malignancy.     

Invasive esophageal aspergillosis associated with acute myelogenous leukemia: successful therapy with combination caspofungin and liposomal amphotericin B

Aspergillosis is one of the most common invasive fungal infections in patients with leukemia. In this patient group, this form of Aspergillus infection is a life-threatening condition with a mortality of 50-100%. The lungs are most often affected, but the esophagus can also be involved.The authors report the case of a child with leukemia who developed invasive esophageal aspergillosis. The condition was diagnosed by microscopic examination of endoscopic biopsy specimens. The patient was already receiving empirical liposomal amphotericin B when the diagnosis was made, so a second antifungal (caspofungin) was added to the regimen. This combination was successful. This case to demonstrates a case of successful treatment of invasive esophageal aspergillosis using combination therapy of liposomal amphotericin B and caspofungin.     

Complete heart block in thalassemia major: a case report

Cardiac complications of iron overload are the most common cause of death in patients with thalassemia major. These complications include recurrent pericarditis, refractory congestive heart failure and rhythm disorders. The usual rhythm disturbances are supraventricular or ventricular premature contractions and first-or second-degree heart block. Complete heart block is a very rare complication of thalassemia major. Herein, we report a case of complete heart block with thalassemia major. The patient also had serious congestive heart failure. Management of the heart block with pacemaker brought no clinical improvement, and she died in the second month of hospitalization.

Aborted sudden cardiac death in a child with left ventricular non‐compaction

Left ventricular non‐compaction is a rare form of cardiomyopathy believed to be the result of intrauterine arrest of compaction of the endomyocardial morphogenesis, leading to persistence of the embryonic myocardium. Clinical manifestations are highly variable, ranging from no symptoms to a progressive deterioration in cardiac function that results in congestive heart failure, systemic thromboemboli, arrhythmias, and sudden cardiac death. Presented here is the case of a 4‐year‐old child with a history of aborted sudden cardiac death. Following resuscitation, he was admitted to the intensive care unit with neurologic sequelae that regressed later on. Transthoracic echocardiography and magnetic resonance imaging showed numerous prominent trabeculations and deep intertrabecular recesses at the apical and anterolateral region of the left ventricle. Electrophysiologic study showed polymorphic ventricular tachycardia. An implantable cardioverter–defibrillator (ICD) was implanted following clinical recovery. Five months after implantation, appropriate ICD shock due to ventricular fibrillation was documented.
