In this, the first report of group B streptococcal (GBS) infections in Asian neonates in South Africa, the incidence was 2.65/1000 live births over a period of 3.5 years. Early onset disease (EOD), defined as arising less than or equal to 5 days after birth, was present in 79% cases; in most of these, the onset was before the age of 24 h. One baby presented with two episodes of late onset GBS infection. The incidence of culture-proven neonatal septicaemia during the same period was 12.3/1000 live births, GBS being commonest organism isolated. It was also the most frequent cause of bacterial meningitis in the newborn, accounting for 89% cases. Although neurological signs were present in 40% patients with EOD, only 13.3% had CSF-culture-positive meningitis. Radiographic features of hyaline membrane disease were found in half of the babies with EOD and for whom a chest radiograph was performed, while one had a pneumothorax. The overall mortality was 13.2% which is much lower than that reported in other series.

The stress response in humans commonly includes elevations in plasma concentrations of glucocorticoids, catecholamines, glucagon, growth hormone, aldosterone, and renin, resulting in alterations in the metabolism of glucose and other energy substrates, and in increased sodium and water retention. In severe illness, triiodothyronine and sometimes thyroxine are decreased without evidence of clinical hypothyroidism. Antidiuretic hormone may be elevated in bacterial meningitis and other central nervous system disorders, as well as in acute asthma, chronic ventilator therapy, pneumothorax, atelectasis, and postoperatively. Increased ADH concentration can lead to significant hypoosmolality and hyponatremia with adverse effects on the patient. In the setting of severe intracerebral insults, ADH may be inappropriately low, resulting in diabetes insipidus. Insulin concentrations may be inappropriately low for serum glucose concentration, or insulin may have diminished receptor responsiveness in seriously stressed patients. Either situation leads to hyperglycemia. Disturbances in calcium, phosphorus, and magnesium homeostasis may occur relatively frequently in the critically ill patient in response to therapeutic interventions, or illness-induced altered metabolism. It is not always clear when an altered metabolic or hormonal state is an appropriate response to a stress, or represents decompensation of the body's mechanisms for coping with that stress. It is important, however to recognize the common responses of the organism to severe illness, and to monitor for treatable abnormalities which occur.

Pneumorrhachis is the presence of air in the spinal canal; mostly, it has an iatrogenic origin. The association of this entity with spontaneous pneumomediastinum without any pneumothorax is rarely reported in the literature. The spontaneous resorption is the usual evolution. The association to acute transverse myelitis is discussed by the authors. The patient is a 21-year-old male with pneumorrhachis associated to a spontaneous pneumomediastinum was admitted at the emergency department for bacterial meningitis. The antibiotherapy has marked the clinical profile by disappearance of the meningeal signs in the 48 h after admission. In contrast, the neurological symptoms were of marked aggravation by appearance of a tetraparesis with a respiratory distress syndrome having required artificial ventilation. The computed tomography (CT) scan showed a typical hypodensity corresponding to paramedullary air extending to several thoracic segments. The spinal magnetic resonance imaging (MRI) showed a high cervical medullary edema without signs of compression. The patient died within 15 days with a profile of vasoparalysis resistant to vasoactive drugs. Pneumomediastinum associated to pneumorrhachis and transverse myelitis complicating purulent meningitis is a rare entity. Although the usual evolution is favorable, the occurrence of serious complications is possible.
