[Coagulation disorders due to burns. Disseminated intravascular coagulation (DIC) and its possible prevention]. / I disturbi coagulativi conseguenti all'ustione. La C.I.D. (coagulazione intravasale disseminata) e la sua possibile prevenzione

Coagulation data were studied in 77 patients with severe burns divided into two groups (A, 45 cases, and B, 32 cases). Increased PDF, platelet deficiency, enhanced fibrinogen turnover, and paracoagulation tests showing disseminated intravascular coagulation were frequent in both groups. Platelet deficiency was significantly more frequent in group A (64.9% of cases) than in group B (37.5%). Patients in the latter group received small subcutaneous doses of heparin from the moment of admission.

[Histopathology of the liver in patients with severe burns. Preliminary biopsy study]. / Istopatologia del fegato nei grandi ustionati. Studio bioptico preliminare

Liver histobiopsy was carried out in 21 patients with burns of from 25 to 75 percent, between the 2nd and 125th day following trauma. The most frequent type of lesion encountered was albuminoid degeneration and hydropic ballooning of the cytoplasm to the point that the parenchyma assumed a "vegetable" appearance. No steatosis intervenes until the 6th-8th day after the burn and where it was not present previously, is a sign that the patient's condition is worsening. Total, or nearly total, disappearance of glycogen from the sections is an indication that the patient is worsening; in effect in patients who died, biopsy carried out shortly beforehand revealed the extreme paucity of PAS-positive material in the hepatocytes.

[The osteocondensing variety of multiple myeloma. Review of the literature and description of a case]. / La varietà osteocondensante del mieloma multiplo. Rassegna della letteratura e descrizione di un caso.

A case of IgG myeloma with eburnation of the femoral and ileoischiopubic bones is described. A review of the literature confirmed the rarity of osteosclerotic myeloma, especially if other possible causes of bone eburnation or the typical contemporary existence of osteolysis are excluded. The hypothesis that osteosclerotic myeloma may constitute an autonomous form of the disease, probably related to the type and/or extent of the proliferating bone is discussed.

[Anomalous immunoelectrophoretic behavior of ceruloplasmin in severely burned patients]. / Anomalo comportamento immuno-elettroforetico della ceruloplasmina nei grandi ustionati

Laurell's two-dimensional technique was employed in a study of the immunoelectrophoretic behaviour of caeruloplasmin in 10 major burn cases. A double peak was noted throughout the entire course. The second peak disappeared on recovery whereas it persisted and was well marked in the case of those who died. It is suggested that this pattern reflects the severe liver damage sustained by burn patients.

[Chronic hepatitis caused by B virus (HBV)]. / Le epatiti croniche da virus B (HBV).

Following a short review of the viruses underlying viral hepatitis and those which, as a secondary factory in the clinical picture, may cause fleeting liver damge, the subdivision of chronic hepatitis conditions on histopathological bases is described. Particular attention is paid to pathogenesis, with a study of the elimination of B virus, correlated to particular histopathological types. A series of 27 PCH and 49 ACH cases is reported. Of special significance was the observation of 14 ACH out of 17 biopsied drug addicts. The therapeutic problem of chronic hepatitis is then tackled.

[Ceftriaxone, a long-acting cephalosporin. Microbiological, kinetic and clinical study]. / Ceftriaxone, cefalosporina "long acting". Ricerca microbiologica, cinetica e clinica.

Ceftriaxone effectively inhibited 332 out of 452 (73.45%) bacterial strains in vitro tests. 291 out of 365 (79.69%) gram negative and 41 out of 87 (47.12%) gram positive strains were inhibited. The tests showed ceftriaxone to be more effective than cephalothin, cephotaxime, cephuroxime, cephamandol and cephoxitin. Kinetic tests showed that cephtriaxone has a plasmatic half life of 7.25 hrs. 24 hours after administration of a 1000 mg venous bolus the drug was still present in the blood. Urinary elimination over a 24 hr. period amounted to means 486.8 mg (48.68%). The drug has liquor transfer capacity. 37 of the 38 patients treated showed complete clinical or clinicobacteriological cure. Improvement was noted in the 38th.

[Piperacillin: microbiological and clinical studies]. / Piperacillina: ricerca microbiologica e clinica.

A microbiological and clinical study of the action of piperacillin is presented. The drug showed an excellent in vitro antibacterial action on gram positive and gram negative microorganisms. Its in vitro action on Ps. aeruginosa (70.8% of strains inhibited) was also extremely interesting, making it the second most effective of the antibiotics tested after polymyxin B and colistin, polypeptides unsuitable for clinical use. In vivo, the administration of piperacillin achieved a clinical and bacteriological cure in 35 out of 40 patients and a clinical cure in 2 out of 40. It was only therapeutically unsuccessful in 3 cases. It is concluded that its microbiological, kinetic and tolerance features make piperacillin suitable for a wide range of therapeutic purposes.

[Microbiological, kinetic and clinical study on a new cephamycin: cefotetan]. / Ricerca microbiologica, cinetica e clinica su una nuova cefamicina: cefotetan.

Microbiological, kinetic and clinical studies were conducted on a new cephamycin, cephotetan. In vitro the antibiotic was found to be very effective against all strains tested. It had a particularly strong action against Gram negative bacteria too. Kinetically speaking, an intravenous bolus produced a high plasmatic concentration with a half life of about 4 hours. Elimination via the kidneys was fastest in the first 3 hours after administration (49.82%) and the slowed down. 82.76% of the dose administered was excreted within 24 hours. This antibiotics is particularly indicated in cases of urinary, respiratory and biliary infections.
