Brown-Séquard-plus syndrome because of penetrating trauma in children.

Brown-Séquard syndrome is an uncommon condition involving incomplete spinal cord injury, with ipsilateral motor and proprioception loss, contralateral pain, and decreased temperature. Brown-Séquard-plus syndrome is associated with additional neurologic findings involving the eyes, bowel, or bladder. We describe an adolescent with Brown-Séquard-plus syndrome attributable to a stab injury. Our patient's clinical features of spinal and neurogenic shock overlapped at presentation. He was managed with high-dose steroids, along with intense physiotherapy and rehabilitation, resulting in good neurologic recovery. Appropriate medical (and surgical, when indicated) management usually results in good to complete recovery of neurologic function, depending on the level and grade of injury. With the increasing incidence of gunshot wounds and stab injuries in children, pediatricians, including pediatric neurologists and emergency physicians, are more likely to encounter these types of spinal cord injuries in children.

Severe methemoglobinemia linked to gel-type topical benzocaine use: a case report.

BACKGROUND: Methemoglobinemia is an uncommon cause of tissue hypoxia, but it can be life threatening if it is not identified and treated promptly. OBJECTIVES: To highlight the importance of understanding the potential risks of over-the-counter medications, especially in unsupervised use. Topical benzocaine must be used with caution, even in the healthy population. CASE REPORT: We report a case of methemoglobinemia secondary to topical benzocaine gel. A 6-year-old boy presented to our Pediatric Emergency Department with cyanosis, vomiting, and lethargy after using a gel-type, 7.5% benzocaine (Baby Orajel) for a toothache. Physical examination revealed dusky blue skin, tachycardia, tachypnea, and a normal neurologic examination. His percutaneous oxygen saturation remained 77-83% despite the administration of 100% oxygen. His arterial blood sample had a dark chocolate color appearance, and methemoglobinemia was suspected. His methemoglobin level was 69.9%, which is considered a lethal level. After a single dose of methylene blue (1 mg/kg/dose), cyanosis was reduced and oxygenation improved. CONCLUSION: Over-the-counter topical benzocaine should be used with caution, and the presence of methemoglobinemia must be promptly identified and treated.

Multiple brain abscesses: an initial presentation in a child with an undiagnosed sinus venosus atrial septal defect.

Cerebral abscess is a serious condition and in children the commonest cause is cyanotic congenital heart disease. We report a 12-year old male who presented with multiple brain abscesses. After an extensive evaluation including a transesphageal echocardiogram (TEE), we found a previously undiagnosed sinus venous atrial septal defect (ASD). He was treated medically with antibiotics. This is an unusual initial presentation of asymptomatic acynotic congenital heart disease in children. We recommended a complete cardiac evaluation including TEE with saline contrast study in the work up of an idiopathic cerebral abscess.

Spontaneous hemopneumothorax in children: case report and review of literature.

Spontaneous hemopneumothorax is rare, occurs in young adolescents, and can be life threatening secondary to massive bleeding. An adolescent with spontaneous hemopneumothorax and shock managed by tube thorascostomy is described here. We compared our case with published data of spontaneous hemopneumothorax in the pediatric age group. Spontaneous hemopneumothorax involves the accumulation of air and blood in the pleural space in the absence of trauma or other obvious causes. Spontaneous hemopneumothorax is usually seen in adolescents, more common in males than females. The common clinical features of spontaneous hemopneumothorax include dyspnoea and chest pain, and 30% present with hypovolemic shock. The bleeding can result from a torn adhesion between the parietal and visceral pleurae, from a rupture of vascularized bullae, or from torn congenital aberrant vessels. Over the last 6 decades, the treatment has progressed from the thoracotomy to minimally invasive techniques such as video assisted thoracoscopic surgery, with great reduction in mortality and recurrence rates. Although a rare entity, diagnosis of spontaneous hemopneumothorax must be considered in young adolescents presenting with spontaneous onset of chest pain and dyspnoea with radiograph findings of hydropneumothorax and/or signs of shock.
