Management of thoracic empyema in children

Abstract The effectiveness of fibrinolytic treatment has been shown in cases of thoracic empyema in adults. In pediatric patients experience is, however, very limited. The aim of this study was to determine the success and complication rates of fibrinolytic treatment in thoracic empyema in children. A series of 25 consecutive children who had loculated pleural empyemas that did not respond to tube thoracostomy and antibiotics is presented. Their ages ranged from 1 to 12 years (mean 4.2). There were 19 boys and 6 girls, and all epyemas were postpneumonic. The fibrinolytic agent used was urokinase in 17 and streptokinase in 8. The mean duration of fibrinolytic treatment was 4.3 days (range 2 to 8) and the mean duration of chest-tube drainage was 8.9 days (range 7 to 13). In 20 patients the fluid output from the chest tube increased significantly after instillation of the fibrinolytic agent, and these patients showed almost complete resolution of the effusion on chest radiograph and ultrasound examinations (80%). Only 5 patients developed complications: bronchopleural fistula and pleural thickening in 3, and recurrent effusion, multiloculation, and pleural thickening in other 2 which were managed by surgical intervention (20%). Our study suggests that intrapleural fibrinolytic treatment is an effective and safe adjunctive therapy in children with thoracic empyema and can obviate a thoracotomy in most cases.

Maternal cocaine abuse resulting in necrotizing enterocolitis. An experimental study in a rat model. II. Results of perfusion studies.

Abstract During the last decade, several publications have appeared associating the maternal use of cocaine and subsequent development of necrotizing enterocolitis (NEC). In 1994, the effects of cocaine in pregnant rats had been reported by this group: a significant decrease in the number of live births, mean birth weight and mean placental weight. In addition, histopathologic examinations revealed severe inflammation and degenerative vascular changes in the uterus and placenta. Severe histopathologic changes resembling NEC such as focal necrosis, necrobiosis, and hemorrhagic inflammatory changes in the gastrointestinal tract of the embryos were also reported. The aim of the second part of this study was to assess the hemodynamic effects of cocaine HCl in pregnant rats and the results of perfusion studies in the uterus, placenta, and fetuses to determine a relation between the dose of drug, hemodynamic changes, and degree of histopathologic findings. Forty-seven Wistar albino rats and 91 rat fetuses were studied: group A (pregnant rats), 16 rats and 91 rat fetuses, group B (non-pregnant rats), 31 rats. Each group was divided into subgroups of cocaine-abused and non-cocaine-abused rats. In each group 2–3 mCi technetium Tc-99m methoxyisobutyl-isonitryl (Sesta MIBI) was injected into the tail vein. Radioactivity counts per g tissue (cps/g) in the uterus, placenta, and fetus were assessed by gamma counter. Cocaine 75 mg/kg per day severely decreased the perfusion of the uterus, placenta, and fetuses. These impairments were statistically significant. In lower doses (30–50 mg/kg per day) no statistically significant changes were observed in the perfusion of the uterus and placenta, but a significant decrease in fetal perfusion was seen. In group B, no significant changes in the perfusion of the uterus due to cocaine were seen. Thus, maternal cocaine abuse results in a reduction in perfusion of the uterus, placenta, and fetus. There was a dose-dependent correlation between the perfusion changes and the development of NEC-like histopathologic changes: the higher the cocaine dose received by the mother, the higher the level of placental and fetal injury. We suggest that perinatal cocaine exposure should be considered a high risk for development of NEC in rat fetuses and embryos. For this reason, infants with a history of possible maternal cocaine abuse or positive urinary cocaine metabolites have to be followed very carefully for NEC.

Severe Hypospadias Associated with Robertsonian Translocation

In this study, we report a 3-year-old boy with severe scrotal hypospadias with Robertsonian translocation [45,XY,t(13q;14q)]. The patient was born at term with a low birth weight and hypospadias. There was no endocrinological abnormality. His father also has a balanced 13–14 Robertsonian translocation. Two-stage hypospadias repair was carried out. The presence of this chromosomal anomaly and hypospadias are unique to our patient, compared to others with the 45,XY,t(13q;14q) translocation. Although no such association has been reported so far, we thought that severe hypospadias in this case might be associated with this translocation.

A very rare cause of intestinal atresia: intrauterine intussusception due to Meckel's diverticulum.

Intrauterine intussusception is one of the rare causes of intestinal atresia.

Transitional cell carcinoma of the bladder presenting after blunt abdominal trauma: A very rare occurrence in childhood

Abstract  Tumors of the urinary bladder are rare in children and nearly all of them are of mesodermal in origin. Herein we report a case of transitional cell carcinoma of the urinary bladder in a 13‐year‐old boy who presented after blunt abdominal trauma. It should be remembered that hematuria could develop after blunt abdominal trauma in children, for reasons other than the trauma itself (e.g. tumors of the urinary tract).

Ultrasound-Guided Percutaneous Drainage of Neonatal Pyometrocolpos Under Local Anesthesia

Hydrometrocolpos is an uncommon congenital disorder with cystic dilatation of the vagina and uterus that occurs as a result of accumulated secretions from the reproductive tract due to distal genital tract obstruction. Secondary infection may also occur, resulting in pyometrocolpos, a potentially lethal disease. Immediate drainage of the cystic mass in patients determined to have pyometrocolpos is required to prevent or treat uropathy and septicemia until definitive corrective surgery can be performed. We report an unusual cause of obstructive uropathy in three infants: pyometrocolpos due to lower genital tract atresia. Ultrasound-guided percutaneous drainage of the pyometrocolpos resulted in dramatically improved clinical and laboratory findings in these patients. Ultrasound-guided percutaneous drainage under local anesthesia is a simple, minimally invasive, safe, and effective procedure that facilitates later successful corrective surgery and avoids the need for more complex drainage procedures.

Open surgical removal of tracheobronchial foreign bodies: A case report

Tracheobronchial foreign bodies can usually be extracted by skillful application of endoscopic techniques. The authors report on experience in the treatment of an infant in whom a plastic object was extracted by an open surgical approach. The authors discussed clinical presentation and treatment options in the treatment of this patient who had a plastic pencil top lodged in the lung. In highly selected cases, an open surgical procedure entails less risk than endoscopic extraction.

Indirect computed tomography sign of renal artery injury: retrograde filling of the renal vein.

Abstract  Computed tomography is a very useful diagnostic tool in childrens trauma. In the present case report, retrograde filling of the renal vein during computerized tomographic examination of a patient with renal trauma is presented. This is an indirect sign of traumatic renal artery injury. This finding might assist in the early diagnosis of severe renovascular trauma.

Treatment of recurrent tracheo-oesophageal fistula in an infant using bronchoscopic I application of fibrin glue

SummaryRecurrent tracheo-oesophageal fistula (TEF) is the most common and serious complication of the treatment of oesophageal atresia with TEF. Following this complication, the patient might need several operations. In this study, the authors report on the treatment of recurrent TEF using bronchoscopic application of fibrin glue (FG) to the fistula tract.
