[Abnormal liver function in Mediterranean spotted fever].

In this study we retrospectively assessed the prevalence of impaired liver function in all 49 patients suffering from Mediterranean Spotted Fever (MSF) consecutively admitted to our department over the last four years. The main parameters of liver function and ultrasound of upper abdomen were performed at entry and at the end of treatment. At admission mean values of transaminases were above the normal limits and significantly higher when compared to mean serum levels at recovery.

Sorbents in acute renal failure and end-stage renal disease: middle molecule and cytokine removal.

Renal replacement therapy in acute renal failure (ARF) and chronic renal failure (end-stage renal disease; ESRD) has been based on the use of modifications of dialysis (continuous arteriovenous hemofiltration and hemodiafiltration) to remove middle-molecular-weight toxins, consisting of low-molecular-weight proteins and peptides (LMWP) and cytokines involved in inflammation. High-flux dialyzers are not efficient at removing LMWP, and for this reason, sorbents have been studied to augment or replace dialysis. Removal of LMWP such as beta2-microglobulin, leptin, complement factor D, angiogenin and cytokines such as interleukin (IL)-1, IL-6, IL-10, IL-18 and tumor necrosis factor-alpha has been established in animal models of sepsis and in ESRD patients using sorbents.

Sorbents in acute renal failure and the systemic inflammatory response syndrome.

Renal replacement therapy in acute renal failure is currently focused on the use of modifications of dialysis (continuous arteriovenous hemofiltration and hemodiafiltration) to remove middle molecular weight toxins, consisting of small proteins, and cytokines involved in the systemic inflammatory response syndrome (SIRS). Conventional high-flux dialyzers are not efficient at removing these molecules, prompting the investigation of sorbents to augment or replace dialysis. Sorbents have been developed to modulate SIRS by targeting cytokines such as IL-1, IL-6, IL-10, IL-18 and TNF, among others.

Acinic cell carcinoma of the lung with metastasis to lymph nodes.

A 64-year-old man presented with an asymptomatic left lower lobe mass. At bronchoscopy there was a tumor in the superior segment. Biopsy revealed an acinic cell carcinoma.

Depression of CD4 T cell subsets and alteration in cytokine profile in boutonneuse fever.

Interferon (IFN)-gamma, interleukin (IL)-10, IL-6, and tumor necrosis factor (TNF)-alpha were significantly increased in sera from Sicilian patients with acute boutonneuse fever (BF) compared with those of healthy controls. IFN-gamma levels dropped sharply within the second week after infection. IL-6, IL-10, and TNF-alpha levels gradually declined; in convalescent patients only were they in the normal range.

[Microbiological and serological study in cases of infertility with or without sterility with particular emphasis on the etiological role of Chlamydia trachomatis].

Microbiological investigations were carried out on two groups of men and women--a) with genital non gonococcal pathology and--b) in infertile/sterile people of the same sex and age (mean age 28.4 y) with the aim to document in them the prevalence of various microorganisms particularly of Mycoplasma/Ureaplasma and Chlamydia trachomatis as aetiological agent of their pathology. Serum antibodies to Chlamydia trachomatis were also studied by microimmunofluorescence, immunoperoxidase and ELISA methods in the same population in comparison with apparently healthy blood donors of the same sex and age as control.

First trimester fetal blood sampling.

The authors report 8 diagnostic cordocentesis performed at the end of the first trimester. The indication was thalassemia (5 cases) and karyotyping (3 cases). The technique requires that the operator holds both the probe and the needle (25 G X 90 mm); the fetal blood sample ranged between 0.

Clinical results and fetal biochemical data in 140 early second trimester diagnostic cordocenteses.

The authors report their experience on 140 diagnostic cordocenteses performed in the early trimester of pregnancy (technique, indications and complications). Furthermore the Authors report preliminary data concerning various fetal blood biochemical parameters (22) obtained by cordocentesis at 18-19 weeks of pregnancy (42 cases). Fetal and maternal values are compared.

Treatment of endometrial hyperplasia with levonorgestrel releasing intrauterine devices.

The effectiveness of a new levo-norgestrel releasing intrauterine device is assessed in fourteen patients with histologically confirmed hyperplastic lesions of the endometrial mucosa. The morphologic response of the hyperplastic endometria to the action of the levo-norgestrel in this study explains the regression of the cases so treated.

An accessory olfactory pathway in Lepidoptera: the labial pit organ and its central projections in Manduca sexta and certain other sphinx moths and silk moths.

In the hawkmoth, Manduca sexta, the third segment of each labial palp contains a pit, which houses a densely packed array of sensilla. We have named this structure the labial pit organ (LPO). The sensilla within the pit are typical of olfactory receptors, characterized by a grooved surface, wall pores, and pore tubules.

Hysteroscopic reversible tubal sterilization.

The Authors describe their experience with a new type of intratubal mechanical device to be inserted under hysteroscopic control. Up to present time, 1471 cycles without any other form of contraception have been observed. Although the promising results of this preliminary report in the field of hysteroscopic reversible tubal sterilization, the Authors underline that this new technique is still evolving and will be improved with further experience.

A sero-epidemiological survey of asymptomatic cases of Boutonneuse fever in western Sicily.

963 sera from contacts, persons from various localities, and blood donors were examined with a commercially produced kit for micro-immunofluorescence for the presence of antibodies to Rickettsia conorii. 10.6% of sera were serologically positive.
