Diagnosis of a neonatal ophthalmic discharge, Ophthalmia neonatorum, in the molecular age: investigation for a correct therapy.

An early double case of acute Ophthalmia neonatorum in 3-day-old twins is reported. Culture of eye swabs showed a wide bacterial polymorphism, in which common bacteria, such as Klebsiella pneumoniae, Streptococcus pneumoniae, Corynebacterium ulcerans and other Enterobacteriaceae, coexisted with atypical Mycoplasmataceae and Chlamydiaceae from resident cervical-vaginal maternal microbiota. The neonates were in an apparently healthy state, but showed red eyes with abundant greenish-yellow secretion, mild chemosis and lid edema.

White-line: a new finding in laryngopharyngeal reflux objective evaluation.

Laryngopharyngeal reflux (LPR) indicates the reflux-induced extra-esophageal disorders. LPR and gastroesophageal reflux disease (GERD) occur by the same mechanism: the escape of gastric contents into the esophagus and beyond. However, the classic GERD symptoms are not typical in LPR disease, which can cause a lot of symptoms none of which is specific, making the diagnosis often elusive.

Can latent synergism of intestinal pathogens be responsible for inflammaging process causing Reiter's syndrome in a young patient HLA-B27 infected by atypical pathogens? A holistic view and clinical biochemical reinterpretation.

A case of a genetically HLA-B27 patient fully investigated by molecular analyses, following a holistic vision and an anamnestic assessment of multi-site ecosystems is repeated. VDRL, Lupus anti-coagulant (LAC) and Widal-Wright (WWR), resulted positive. The antibodies (IgG/IgA anti-Ct) against chronic Chlamydia trachomatis inflammation were positive.

Management of superficial vein thrombosis and thrombophlebitis: status and expert opinion document.

Superficial vein thrombosis is characterized by clotting of superficial veins (ie, following direct trauma) with minimal inflammatory components. Superficial thrombophlebitis is a minimally thrombotic process of superficial veins associated with inflammatory changes and/or infection. Treatments generally include analgesics, elastic compression, anti-inflammatory agents, exercise and ambulation, and, in some cases, local or systemic anticoagulants.

Prevention of influenza episodes with colostrum compared with vaccination in healthy and high-risk cardiovascular subjects: the epidemiologic study in San Valentino.

The efficacy of a 2-month treatment with oral colostrum in the prevention of flu episodes compared with antiinfluenza vaccination was evaluated. Groups included healthy subjects without prophylaxis and those receiving both vaccination and colostrum. After 3 months of follow-up, the number of days with flu was 3 times higher in the non-colostrum subjects.

Improvement of diabetic microangiopathy with pycnogenol: A prospective, controlled study.

The aim of this study was to investigate the clinical efficacy of oral Pycnogenol (Horphag Research Ltd, United Kingdom) in patients with diabetic microangiopathy. Patients without a history of diabetic ulcerations were treated with Pycnogenol. Patients received oral Pycnogenol (50 mg capsules, 3 times daily for a total of 150 mg daily for 4 weeks).

Myocardial antioxidant defense mechanisms: time related changes after reperfusion of the ischemic rat heart.

It is well known that reperfusion damage of ischemic myocardium may be attributed to alterations in the antioxidant defense system against free radical aggression. In addition, the degree of myocardial damage may depend on the duration and severity of ischemia that precedes reperfusion. We carried out serial ischemic experiments (10, 30, 60 and 120 min) in ex-vivo rat hearts followed by 30 min reperfusion and we assayed the glutathione-dependent enzymatic activities (selenium-dependent glutathione-peroxidase: GSH-Px; selenium-independent glutathione peroxidase: GST-Px; glutathione-transferase: GST and glutathione-reductase: GS-SG-Red), Catalase activity (CAT) and non-proteic thiol compounds (NP-SH) at the end of reperfusion.

Interaction of glutathione transferase from horse erythrocytes with 7-chloro-4-nitrobenzo-2-oxa-1,3-diazole.

7-Chloro-4-nitrobenzo-2-oxa-1,3-diazole reacts with two thiol groups of the dimeric horse erythrocyte glutathione transferase at pH 5.0, with strong inactivation reversible on dithiothreitol treatment. The inactivation kinetic follows a biphasic pattern, similar to that caused by other thiol reagents as recently reported.

Aortic glutathione-related antioxidant defences in rabbits subjected to suprarenal aortic coarctation hypertension.

In seven rabbits subjected to suprarenal aortic coarctation hypertension, the segments above and below the coarctation were tested for the antioxidant defences (i.e. acid-soluble thiol compounds, selenium-dependent and selenium-independent glutathione peroxidase, glutathione reductase, glutathione transferase) and thiobarbituric acid-reactive substances.

Regional distribution of glutathione-related antioxidant defences in the normal rabbit aorta.

In 6 normal rabbits, the aortic arch, the descending thoracic and the abdominal aorta were tested for non proteic thiol compounds, selenium-dependent and selenium-independent glutatione peroxidase, glutatione reductase, glutatione transferase and thiobarbituric acid reactive substances. The aortic arch showed the greatest content of non proteic thiol compounds and thiobarbituric acid reactive substances, associated to the highest activities of glutathione-related enzymes. However, not significant differences were detectable between aortic arch and descending thoracic aorta, except for the glutathione transferase activity (0.

Aortic antioxidant defence mechanisms: time-related changes in cholesterol-fed rabbits.

In 24 rabbits fed a hyperlipidic diet (0.5% cholesterol, 5% lard and 5% peanut oil) for 10 (group A1), 30 group B1) and 60 days, (Group C1), compared to 24 control rabbits fed a standard diet for the same periods, antioxidant defence system (total superoxide dismutase, catalase, total thiol compounds selenium-dependent and selenium-independent glutathione peroxidase, glutathione reductase, glutathione transferase) and lipid peroxidation (thiobarbituric acid-reactive substances) in the aortic wall were tested. The percent of intima with grossly apparent atherosclerosis, is assessed by staining with the lipophilic dye Sudan IV, was negligible in group A1, but increased progressively in groups B1 (22.

Elevation of glutathione transferase activity in human lung tumor.

Glutathione transferase activity in the cytosolic fractions of human lung tumors was found to be significantly higher than that present in the corresponding non-tumor cytosolic fractions. The relative activities of 'cationic', 'near-neutral' and 'acidic' glutathione transferases of both tumor and non-tumor cytosols were estimated after isoelectric focusing. More than 90% of activity in both tumor and non-tumor cytosols was found to be associated with the 'acidic' (pI 4.

A study on the in vitro interaction between tyrosinase and glutathione S-transferase.

The actions of glutathione S-transferase and tyrosinase on the in vitro production of glutathionyl-3,4-dihydroxyphenylalanine and the dopachrome level in the presence of GSH and L-3,4-dihydroxyphenylalanine were studied. No clear evidence of complementarity between tyrosinase and glutathione S-transferase was observed; on the contrary, in the presence of glutathione S-transferase the glutathionyl-3,4-dihydroxyphenylalanine yield was lower than with tyrosinase only, as measured by HPLC. It is concluded that the spontaneous conjugation of GSH with dopaquinone should probably be high enough to scavenge the toxic quinone and to produce precursors for phaeomelanogenesis.

Selenium level and glutathione-dependent enzyme activities in normal and neoplastic human lung tissues.

Selenium, glutathione peroxidase, glutathione reductase and glyoxalase I have been measured in normal and neoplastic human adult lung tissues. Interindividual variations of enzyme activities and selenium content in both tumour and non-tumour tissues were considerable. From the measurements of glutathione peroxidase activity with both hydrogen peroxide and cumene hydroperoxide it was deduced that human tumour and non-tumour lung tissues are devoid of the selenium-independent enzyme.

Glutathione transferase activity during Bufo bufo development.

High levels of glutathione transferase activity were measured during the development of the embryos of Bufo bufo including unfertilized eggs. After stage 4 glutathione transferase activity gradually decreased until stage 25 when the minimum was reached. No change in the number of isozymes was noted during development according to isoelectric focusing analysis performed on the cytosolic fractions of selected stages.
