All trans-retinoic acid (ATRA) syndrome is a life-threatening complication of uncertain pathogenesis that can occur during the treatment of acute promyelocytic leukemia (APL) by ATRA. Since its initial description, however, no large series of ATRA syndrome has been reported in detail. We analyzed cases of ATRA syndrome observed in an ongoing European trial of treatment of newly diagnosed APL. In this trial, patients 65 years of age or less with an initial white blood cell count (WBC) less than 5,000/microL were initially randomized between ATRA followed by chemotherapy (CT) (ATRA-->CT group) or ATRA with CT started on day 3; patients with WBC greater than 5,000/microL received ATRA and CT from day 1; patients aged 66 to 75 received ATRA-->CT. In patients with initial WBC less than 5, 000/microL and allocated to ATRA-->CT, CT was rapidly added if WBC was greater than 6,000, 10,000, 15,000/microL by days 5, 10, and 15 of ATRA treatment. A total of 64 (15%) of the 413 patients included in this trial experienced ATRA syndrome during induction treatment. Clinical signs developed after a median of 7 days (range, 0 to 35 days). In two of them, they were in fact present before the onset of ATRA. In 11 patients, they occurred upon recovery from the phase of aplasia due to the addition of CT. Respiratory distress (89% of the patients), fever (81%), pulmonary infiltrates (81%), weight gain (50%), pleural effusion (47%), renal failure (39%), pericardial effusion (19%), cardiac failure (17%), and hypotension (12%) were the main clinical signs, and 63 of the 64 patients had at least three of them. Thirteen patients required mechanical ventilation and two dialysis. A total of 60 patients received CT in addition to ATRA as per protocol or based on increasing WBC; 58 also received high dose dexamethasone (DXM); ATRA was stopped when clinical signs developed in 30 patients. A total of 55 patients (86%) who experienced ATRA syndrome achieved complete remission (CR), as compared with 94% of patients who had no ATRA syndrome (P = .07) and nine (14%) died of ATRA syndrome (5 cases), sepsis (2 cases), leukemic resistance (1 patient), and central nervous system (CNS) bleeding (1 patient). None of the patients who achieved CR and received ATRA for maintenance had ATRA syndrome recurrence. No significant predictive factors of ATRA syndrome, including pretreatment WBC, could be found. Kaplan Meier estimates of relapse, event-free survival (EFS), and survival at 2 years were 32% +/- 10%, 63% +/- 8%, and 68% +/- 7% in patients who had ATRA syndrome as compared with 15% +/- 3%, 77% +/- 2%, and 80% +/- 2% in patients who had no ATRA syndrome (P = .05, P = .003, and P = .03), respectively. In a stepwise Cox model that also included pretreatment prognostic variables, ATRA syndrome remained predictive for EFS and survival. In conclusion, in this multicenter trial where CT was rapidly added to ATRA in case of high or increasing WBC counts and DXM generally also used at the earliest clinical sign, the incidence of ATRA syndrome was 15%, but ATRA syndrome was responsible for death in only 1.2% of the total number of patients treated. However, occurrence of ATRA syndrome was associated with lower EFS and survival.

The transition from mechanical ventilation to spontaneous breathing in the intensive care unit is a two-stage process: weaning and extubation. Certain parameters require consideration before the commencement of weaning, namely respiratory function (both pulmonary gas exchange and respiratory muscle strength), cardiovascular status, stability of clinical condition, low metabolic demands, psychological factors and, possibly, patient collaboration. Appropriate sedation is crucial for successful weaning to keep the patient rested and to maintain the oxygen consumption and carbon dioxide production low. In this review, three types of patient are considered: patients having short-term ventilation after trauma or surgery, those having long-term ventilation for chronic pulmonary disease, and those with other associated severe organ dysfunction, such as heart failure. Strategies for weaning are outlined for each of these situations and the role of sedation is discussed. Making the transition from mechanical ventilation to unassisted spontaneous breathing can be a difficult process, particularly for those patients in the intensive care unit (ICU) requiring prolonged ventilatory assistance for severe respiratory failure secondary to: exacerbation of chronic obstructive airways disease (COAD) acute respiratory distress syndrome (ARDS) underlying diseases affecting cardiac function. This transition may be considered to comprise two separate stages, namely weaning and extubation. Weaning consists of preparation for spontaneous breathing supported and monitored by a mechanical ventilator and attendant monitoring of all the important vital parameters, while extubation marks the final switch to unsupported spontaneous breathing, which may be quite a big step for the patient. Important weaning parameters.

A 34-year-old Japanese woman (gravida 2, para 2) with polyhydramnios and non-immunological hydrops fetalis was referred to our department at 32 weeks of gestation. On admission, the blood pressure was 120/60 mmHg and there was no pitting edema of the lower extremities. An ultrasound examination disclosed a large placental tumor 5.8 cm x 4.4 cm x 4.8 cm. Fetal lung compression was suspected because the lung-thorax transverse area ratio was 0.13. The preload index of the inferior vena cava was 0.74, suggesting fetal cardiac failure. After fetal pleural effusion was aspirated, lung compression developed. Cordocentesis was performed at 33 weeks of gestation, and the fetal karyotype was confirmed to be 46, XY from an umbilical blood cultivation. The patient underwent a cesarean section at 33 weeks of gestation due to severe uterine contraction after preterm PROM. The baby was a 3,840 g male with a distended abdomen. Apgar score at 1 minute was 1. A chest X-ray demonstrated respiratory distress syndrome. The baby was discharged on the 69th day after birth and he is now 2 years and 9 months old and healthy.

PDA (patent ductus arteriosus) is a common congenital heart disease. Usually surgical intervention through left thoracotomy or recently through video assisted thoracoscopy will be recommended if the preceding or intent medical treatment fails or is contraindicated. However, once surgical intervention is decided, various complications are still a real fear in the mind of the surgeon and the anesthesiologist, particularly if the infant is premature or very sick. Here we report an anesthetic management in a female preterm infant weighing 500 grams, who underwent PDA ligation. She was born at gestation age of 28 weeks at our hospital, and since her birth she was noted to have infant respiratory distress syndrome associated with renal dysfunction. She was admitted to the neonatal intensive care unit (NICU) straightaway. After thorough examination, a severe PDA was disclosed. The possibility of pulmonary hemorrhage and heart failure could be predicted in view of the large left to right shunt. Worst of all was that her poor renal function contradicted a medical treatment. So we decided to carry out the ligation procedure at once although she was premature and only 5 days old. The NICU was chosen as the operation theater for transferring concerns. General anesthesia was induced and maintained by atropine 0.01 mg, pancuronium 0.1 mg, fentanyl 2 micrograms, and ketamine 0.15 mg intravenously. Supplemental oxygen was given throughout the operation. The PDA was ligated through left thoracotomy and blood loss was minimal. The peri-operative course was uneventful. The patient recovered well following surgery and anesthesia.

Diabetic fetopathy is still a common clinical problem correlated with a high morbidity of the neonate. These children are often macrosome, suffer from respiratory distress syndrome due to delayed lung maturity, acidosis, hypoglycaemia, electrolyte-imbalances and polycythaemia. We describe a male neonate with diabetic fetopathy as a result of gestational diabetes of the mother. In addition to the symptoms described above, our patient clinically presented with severe hypertrophy of the right ventricle associated with intrauterine heart failure. The boy was born with serious prenatal asphyxia which made initial neonatal intensive care treatment necessary. The hypertrophic cardiomyopathy normalized within 6 weeks after birth without further treatment. Different causes of a hypertrophic cardiomyopathy (infections, metabolic disorders, neurologic affections, syndromes) could be ruled out, so that the diabetic fetopathy was the most probable cause for the condition. If we are looking at the heart only, this case-report suggests a good prognosis of septumhypertrophy as well as right ventricular hypertrophy in patients with diabetic fetopathy. The case also elucidates that not only the diabetes type I can entail serious fetal damage but also gestational diabetes can. Therefore, in suspect mothers screening for gestational diabetes should be expanded to oral glucose tolerance testing.

We describe the case of a patient with a neonatal giant cutaneous hemangioma with high-output cardiac failure and Kasabach-Merritt syndrome and successfully treated with transcutaneous arterial embolization aimed at controlling severe congestive heart failure and consumption coagulopathy. A patient was admitted to the neonatal care unit on the first day of age because of a large hemangioma on his right lateral chest wall and respiratory distress, associated with cardiac failure resulting from arteriovenous shunting. On the second day of age the platelet count decreased to 5.7 x 10(4)/microliter and fibrinogen level was 85 mg/dl. The values of prothrombin time and activated partial thromboplastin time were prolonged. Intravenous predonisone therapy was started immediately, but bleeding tendency was getting worse and the evidence of congestive heart failure persisted. On the third day the patient then underwent embolization of feeding arteries with microcoils. The cardiac failure and thrombocytopenic coagulopathy had improved significantly without complications. We conclude that transcutaneous arterial embolization is an effective and safe treatment in this neonate and should be considered for the treatment of control high-output cardiac failure and coagulopathy in infants with hemangioma and Kasabach-Merritt syndrome.

Paralysis of the diaphragm may cause life-threatening respiratory distress in infants and young children because of paradoxical motion of the affected diaphragm and contralateral shift of the mediastinum during expiration. Phrenic nerve injury (PNI) may follow chest operations. 10 children with diaphragmatic paralysis and severe respiratory distress underwent plication of the diaphragm. Ages ranged from 14 days to 5 years. 9 had PNI after operations for congenital heart disease and 1 after resection of an intraspinal cervical lipoma. The right side was affected in 7, the left in 3. Indication for surgery was inability to wean from mechanical ventilation, which had ranged from 11 to 152 days (median 35). 8 underwent plication via a thoracic approach and 2 via an abdominal approach. There were no complications directly related to the operation. The interval from plication to weaning from mechanical ventilation ranged from 2 to 140 days (median 4). 1 patient died 2 hours after plication due to severe heart failure and 2 after prolonged hospitalization due to sepsis and multi-organ failure. 6 were extubated 2-8 days (median 4) after plication and 1 only after 40 days. Early diaphragmatic plication is simple and avoids more serious surgery. While effective in ventilator-dependent infants and young children, it should not be used in those with multi-organ failure. Early plication may prevent the complications of prolonged mechanical ventilation.

Extralobar sequestration usually presents during the first months or years of life by respiratory distress, cyanosis or infection. Cardiac failure is a rare mode of presentation. If surgery is the usual treatment, radiological endovascular treatment has occasionally been described. We report the case of a newborn who underwent endovascular treatment at 19 days. Clinical status is excellent at 5.5 year follow-up.

We present a neonate with a cervicofacial haemangioma complicated by the Kasabach-Merritt syndrome, respiratory distress due to airway compression and high-output heart failure. This haemangioma and intravascular disseminated coagulation, treated initially by aspirin, ticlopidine and corticosteroids, required more invasive treatment with superselective embolisation and interferon alpha-2a. The clinical outcome was good.

Persistent pulmonary hypertension of the newborn (PPHN) is a cardiopulmonary disorder characterized by systemic arterial hypoxemia secondary to elevated pulmonary vascular resistance with resultant shunting of pulmonary blood flow to the systemic circulation. This disorder can be classified into four forms dependent on the etiology of the pulmonary hypertension: (1) Hypoplastic lung associated with congenital diaphragmatic hernia and oligohydramnions. (2) Primary PPHN (without known causative factor), such as preterm PPHN. (3) Secondary PPHN (with known causative factor), such as meconium aspiration syndrome, birth asphyxia or respiratory distress syndrome. (4) Relative PPHN associated with heart failure of hydrops fetalis or ischemic myocardial dysfunction. Inhalation of nitric oxide, which previously known as endothelial-derived-relaxation-factor, has been studied intensively as therapy for PPHN.
