    OBJECTIVE: The present study evaluated indications’ validity of cervicoscopic and microcolposcopic examination in LSIL patients with unsatisfactory or negative colposcopy. MATHERIAL AND METHODS: In the cervico-vaginal pathology unit of the “San Giovanni Calibita Fatebenefratelli” University of Rome “Tor Vergata”, 119 patients with a positive cervical cytology (LSIL), were submitted to the exam for the following two indications: 1) unsatisfactory colposcopy 37 (31.1%); 2) negative colposcopy 82 (68.9%). RESULTS: Cervicoscopy allowed the SCJ visualization in 115 (9.6%) patients. In 4 patients 3.4%, the SCJ visualization was not possible due to cervical stenosis. Cervicoscopy without staining, revealed endocervical squamous columnar junction in 33 (28.7%) patients. The blue dye in panoramic view detected endocervical SCJ in 41 (35.7%), out of 115 patients (>5 mm in 34 (29.6%) patients and >10 mm in 7 (6.1%)). CONCLUSIONS: Cervicoscopic examination revealed 7.8% of CIN2-3 in LSIL patients with inadequate or negative colposcopy. In patients with negative colposcopy the percentage of undiagnosed lesions inside the cervical canal was very low. The blue dye added sensitivity to the exam

    Atrial natriuretic factor

    The discovery of the first well-defined natriuretic hormone, the Atrial Natriuretic Factor (ANF), has prompted research on its impact on volume regulation in health and disease. The natriuretic, diuretic, and smooth muscle-relaxing properties suggest an important role of this novel hormone in pathophysiological states with sodium or volume retention, such as congestive heart failure or cirrhosis of the liver. Investigations on the implications of ANF in liver disease have been performed for little more than 1 year, and results are still controversial in many respects. At present, it seems very likely that there is no absolute deficiency of plasma ANF in patients with cirrhosis. Moreover, elevated plasma levels in cirrhotics with ascites have been reported by several groups. However, as yet, a molecular characterization of this increased immunoreactivity is still lacking. There is disagreement on the reduced release of and renal response to ANF in subgroups of cirrhotics; however, stimulus-response-coupling might be impaired. Further studies are needed to elucidate the pathophysiological implications and therapeutical potential of ANF in patients with chronic liver disease

    Theories of schizophrenia: a genetic-inflammatory-vascular synthesis

    BACKGROUND: Schizophrenia, a relatively common psychiatric syndrome, affects virtually all brain functions yet has eluded explanation for more than 100 years. Whether by developmental and/or degenerative processes, abnormalities of neurons and their synaptic connections have been the recent focus of attention. However, our inability to fathom the pathophysiology of schizophrenia forces us to challenge our theoretical models and beliefs. A search for a more satisfying model to explain aspects of schizophrenia uncovers clues pointing to genetically mediated CNS microvascular inflammatory disease. DISCUSSION: A vascular component to a theory of schizophrenia posits that the physiologic abnormalities leading to illness involve disruption of the exquisitely precise regulation of the delivery of energy and oxygen required for normal brain function. The theory further proposes that abnormalities of CNS metabolism arise because genetically modulated inflammatory reactions damage the microvascular system of the brain in reaction to environmental agents, including infections, hypoxia, and physical trauma. Damage may accumulate with repeated exposure to triggering agents resulting in exacerbation and deterioration, or healing with their removal. There are clear examples of genetic polymorphisms in inflammatory regulators leading to exaggerated inflammatory responses. There is also ample evidence that inflammatory vascular disease of the brain can lead to psychosis, often waxing and waning, and exhibiting a fluctuating course, as seen in schizophrenia. Disturbances of CNS blood flow have repeatedly been observed in people with schizophrenia using old and new technologies. To account for the myriad of behavioral and other curious findings in schizophrenia such as minor physical anomalies, or reported decreased rates of rheumatoid arthritis and highly visible nail fold capillaries, we would have to evoke a process that is systemic such as the vascular and immune/inflammatory systems. SUMMARY: A vascular-inflammatory theory of schizophrenia brings together environmental and genetic factors in a way that can explain the diversity of symptoms and outcomes observed. If these ideas are confirmed, they would lead in new directions for treatments or preventions by avoiding inducers of inflammation or by way of inflammatory modulating agents, thus preventing exaggerated inflammation and consequent triggering of a psychotic episode in genetically predisposed persons

    Comparison of intensified traditional insulin therapy and micropump therapy in pregnant women with type 1 diabetes mellitus

    Ten pregnant women, affected by type I diabetes mellitus, observed for the first time during the II-III month of pregnancy, were examined. These patients were divided in two groups at random: group A underwent continuous subcutaneous insulin infusion with micropump CPI 9100 Lilly; group B underwent intensified insulin therapy with three daily doses of MC rapid insulin, two of which associated with MC intermediate insulin. All the patients were able to monitor their own blood glucose levels at home by means of reactive strips and reflectometer. In both the groups the mean glycemic values during fast and two hours after meals, and the eventual presence of urinary keton bodies and hypoglycemic crisis were evaluated during the course of pregnancy: these parameters turned out to be identical in the two groups. The increased need of insulin, the maternal body weight gain, the week and mode of delivery, the neonatal weight and the maternal and fetal complications also turned out to be identical in the two groups. To conclude, a good maternal metabolic control can be obtained either with the intensified conventional insulin therapy of with micropumps, if the patients, being properly instructed, are responsible for the monitoring of their own blood glucose levels at home
