We report experiences in 3 patients with acromegaly while using the somatostatin analogue octreotide. In case 1, a 44 year old male developed pneumococcal meningitis 3 months after having transphenoidal surgery for a pituitary tumour. This occurred with the re-emergence of communication between the surgical tract and the C.S.F. In case 2 a 52 year old male with insulin resistant diabetes mellitus requiring 240 units/day, with greatly elevated growth hormone concentrations was able to stop insulin within 5 days of starting octreotide. In case 3, a 52 year old male with sleep apnoea syndrome, respiratory failure and resistant heart failure made a dramatic improvement which is maintained 2 years later. All cases were associated with substantial falls in growth hormone and insulin like growth factor-1 concentrations.

Septic arthritis is a rarely reported manifestation of disease due to Streptococcus pneumoniae. We have reviewed our recent experience of this disease in 14 adult patients. Common features in patients with S. pneumoniae septic arthritis included advanced age (median=63 y), pre-existing joint disease (6/14), large joint disease (14/14), polyarthritis (6/14), and associated meningitis, pneumonia or both (6/14). Two patients with septic arthritis and meningitis, and another with Down's syndrome and sleep apnoea, died during treatment. In the remaining 11 patients, treatment for at least 19 d, predominantly with intravenous benzyl penicillin, plus joint lavage, resulted in cure.

Among 27,000 infants studied prospectively to characterize their sleep-wake behavior, 38 infants died under 6 months of age (including 26 infant victims of sudden infant death syndrome (SIDS), 5 with congenital cardiac abnormalities, 2 from infected pulmonary dysplasia, 2 from septic shock with multi-organ failure, 1 with a prolonged seizure, 1 from prolonged neonatal hypoxemia, 1 from meningitis and brain infarction). The frequency and duration of sleep apneas recorded some 3-12 weeks before the infants' death were analyzed. Brainstem material from these 38 infants was studied in an attempt to elucidate the relationship between sleep apnea and neuronal pathological changes in the arousal pathway. Immunohistochemical analyses included the evaluation of growth-associated phosphoprotein 43 (GAP43) as a marker for synaptic plasticity. The terminal-deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) method was used to identify apoptosis. The positive pathological reactions were quantitatively analyzed. The pathological and physiological data were linked for each infant. Akaike Information Criterion (AIC) statistics was calculated to elucidate the relationship between the physiological and the pathological data in the SIDS victims. The findings illustrated the possibility of an organic fragility within the arousal pathway, particularly in the midbrain periaqueductal gray matter, which is associated with the "visceral alerting response". This autonomic response occurs within an acetylcholine afferent system and pedunculopontine tegmental nucleus (PPTN). The finding is, in future SIDS infants, associated with repetitive sleep apnea.

Among 27,000 infants studied prospectively to characterize their sleep-wake behavior, 38 infants died suddenly and unexpectedly under 6 months of age. Of these, 26 died from sudden infant death syndrome (SIDS), 5 from congenital cardiac abnormalities, 2 from infected pulmonary dysplasia, 2 from septic shock with multi-organ failure, 1 from a prolonged seizure, 1 from prolonged neonatal hypoxemia, and 1 from meningitis and brain infarction. The frequency and duration of apneas recorded some 3-12 weeks prior to the infants' death were analyzed. The brainstem materials were collected and studied in an attempt to elucidate the relationship between sleep apnea, and prone sleep position and gliosis in some nuclei associated with cardiorespiratory characteristics, such as nucleus ambiguus in the medulla oblongata and the solitary nucleus, as well as structures associated with arousal phenomenon, such as the reticular formation, the superior central nucleus and the nucleus raphe magnus in the pons, the dorsal raphe nuclei in the midbrain and medulla oblongata, periaqueductal gray matter in midbrain, and locus ceruleus. Gliosis was estimated as the density of glial fibrillary acidic protein (GFAP)-positive reactive astrocytes. Variant-covariant analyses were carried out using the characteristics of apnea as an independent variable and sleep position and gliosis as dependent variables. A significant association was found only in the frequency of obstructive apnea and prone position (P<0.001) and gliosis in the raphe nuclei in the midbrain (P<0.001). Although prone position is a well-known risk factor for SIDS, the frequency of obstructive apnea has not been associated with the prone sleep position. The observed relation between prone sleep and the density of gliosis does not relate to epidemiological findings. Further studies are needed to investigate the unexpected statistical association.
