RESUMEN
BACKGROUND: Materno foetal infection (MFI) remains one of the major causes of neonatal morbidity and mortality. Early detection of neonatal sepsis can be difficult, because the first signs of the disease may be unspecific and similar to symptoms of other non-infectious processes. AIM: We aimed to investigate the role of procalcitonin (PCT) in the diagnosis of fetal infection (MFI), and to compare it with those of the C-reactive protein (CRP). METHODS: We have conducted a prospective study during 20 months: which concerned 25 newborns suspected of MFI and admitted before 12 hours of life. All newborn had anamnestic and/or physical signs of possible infection. MFI was confirmed in newborns with positive bacterial analysis. CRP and PCT were determined in the sera at H12, H24, H36 and H48. Newborns were divided into: patients with recognized MFI (group 1), patients with possible MFI (group2) and non infected newborns (group 3): RESULTS: The specificity of PCT was 80% versus 27% for the CRP. Negative predictive value of PCT was 85% versus 66% for the CRP. The mean values, at H12, H24, H36 and H48, of PCT for newborn who had MFI were statistically grater than those for no infused group (p<0.05). No statistical difference was observed concerning CRP values. CONCLUSIONS: PCT may a useful tool in early diagnosing of MFI; it has better specificity and negative predictive value than CRP.

PURPOSE: The aim of our retrospective study was to explore the clinical and metabolic characteristics of newly diagnosed diabetes patients over the age of 30 years. METHODS: Study participants were consecutive, newly diagnosed patients with diabetes, over the age of 30 years, presenting to our university hospital department between January 1999 and June 2003. Clinical and metabolic data were collected retrospectively by medical record review. RESULTS: Three hundred seventy patients were included; mean age was 54.1+/-14.0 years; 49% were women and a family history of diabetes was reported in 52% of patients. Patients presented with acute complications in 40% of cases. Symptoms of polyuria-polydipsia and weight loss were present at diagnosis in 87% and 76% of cases respectively. 58% of our patients were obese or overweight (BMI> or =25 kg/m(2)), hypertension was present in 22%, hypertriglyceridemia in 27% and high LDL cholesterol in 27%. Neuropathy was diagnosed in 24%, nephropathy in 13%, coronary heart disease in 9%, retinopathy in 8% of cases, stroke in 3% and peripheral arterial disease in 2%. Insulin was prescribed initially in 47% of cases. CONCLUSIONS: Our results demonstrate that clinical symptoms and acute ketosis are the most common presenting features of diabetes mellitus in adults at the hospital level. Associated chronic complications are frequent.
