[Cyclosporin A in immunosuppressive therapy of kidney transplants (clinical results in 55 patients)].

The authors report the results of a clinical study of the use of cyclosporin A plus low-dose steroids in a consecutive series of 55 kidney transplants with follow-up ranging from 6 to 20 months. The clinical results (rejects, immunosuppressant side effects, 12-month survival of transplant and patient) are compared with those of a similar group of patients on "traditional" therapy (azathioprine plus high-dose steroids). The results of the study confirm the efficacy of cyclosporin A in preventing and controlling acute reject crises in the course of allogenic transplant, though many of the problematic issues related its clinico-therapeutic management remain open questions.

[Malignant neoplastic pathology in patients given a kidney transplant].

The incidence of malignant neoplasms in patients subjected to pharmacological immunosuppression following kidney transplantation is higher than that observed in the control population at large. In our unit, in a study population of 451 patients undergoing a total of 462 kidney transplants over the period from 1968 to 1986, four malignant neoplasms (0.9%) were observed in 3/369 (0.8%) patients treated with azathioprine (1 ovarian papilliferous cystoadenoma, 1 embryonal carcinoma of the testicle and 1 Kaposi's sarcoma) and in 1/93 (1.1%) patients treated with cyclosporin (1 Kaposi's sarcoma). The neoplasm was successfully controlled only in the first case after bilateral extended adnexectomy.

Safety profile of ofloxacin: the Italian data base.

In clinical trials performed in Italy, 2,003 patients, suffering from various infectious diseases, have so far been treated with ofloxacin. In most cases dosages of 200 mg, 300 mg or 400 mg b. i. d. have been used. In all, 130 adverse reactions have been recorded in 116 patients (5.8%): gastrointestinal events (mostly nausea, vomiting and gastric pain) in 4.8% of the patients, neurological events (mostly headache and insomnia) in 0.7%, cutaneous reactions in 0.4% and others in 0.5% cases. The drug-event causal relationship was assessed by the investigators as unlikely in 5.0% of the events, as possible in 47.1%, as probable in 31.4% and as almost certain in 16.5%. The severity of adverse reactions was judged as mild in 55% of the cases, as moderate in 38% and as severe in 7%. In 30 patients (1.5%), treatment was discontinued because of occurrence of side effects. Abnormal laboratory values probably related to treatment were reported in 25 patients (2.1%). Ofloxacin is well tolerated and shows a safety profile comparable with that of the best tolerated oral antibacterials.

[Spontaneous perirenal extravasation of urine].

Perirenal urinary extravasation in the course of violent renal colic appears to occur much more frequently than is reported in the literature. In this study, the authors report on three such cases observed personally in the space of one year and discuss the pathophysiological factors which may give rise to this phenomenon.

[Adenomatoid tumor of the epididymis].

Primary tumors of the epididymis are very rare. The neoplasms most frequently affecting the epididymis are adenomatoid tumors. In this report, the authors describe a case observed personally. Various histogenetic hypotheses and the histological characteristics of the tumor are discussed.

[Primary retroperitoneal tumors (clinical findings in yolk sac tumor, vascular leiomyosarcoma and extraosseous chondrosarcoma)].

Primary retroperitoneal tumors (PRT) constitute about 0.02 per cent of all tumors examined in the Department of Pathology of our hospital. We report 3 cases of malignant PRT - yolk-sac tumour, vascular leiomyosarcoma and extraskeletal chondrosarcoma - selected for their histological rarity and clinical features. Recent techniques available for the diagnosis of these neoplasms and surgical treatment are discussed. The role of radio-chemotherapy is also dealt with.

[Adenoma nephrogenic. Morphologic aspects].

Nephrogenic adenoma is a rare lesion of urothelial mucous membrane. At present, the cases described in literature are 85. In this work the Authors study the morphologic aspects and etiopathogenetic theories.

[Spontaneous rupture of the transplanted kidney].

The spontaneous breakage of a kidney is a rare complication which may occur in the first weeks after a transplantation. The cause which can determine it is not yet cleared up, although the Authors think the greatest responsibility for this can be ascribed to rejection. In this work the authors report the experience and casuistry of the Transplantation Centre of Verona.

[Lymphocele after renal transplant: considerations based on a clinical case].

The Authors study again the problems of lymphocele in kidney transplantation by showing an interesting clinical case: a lymphocele with smallest size, developing an intensively compressive action on iliac vein. In the light of the experience of 354 transplantations, they discuss the etiopathology and clinics thereof. They particularly emphasize the diagnostical role of echography. Whereas the asymptomatic lymphoceles require no treatments for their trend to be reabsorbed, the symptomatic ones need a quick solution of the compressive effect. Then they consider the therapeutical solutions suggested as an alternative to the interperitoneal marsupialization, which remains the most widely used method.

[Gastric leiomyoma (presentation of 3 clinical cases)].

Gastric leiomyoma represents a rather rare report in abdominal surgery, above all because it very often shows no symptoms. Among the non-epithelial gastric neoplasms, it occupies the second place after lymphoma. After describing its anatomo-pathological aspects and clinical features, the authors report their casuistry, including three observations of such neoplasm, and point out that both the endoscopic inspection and the bioptic abstraction, contextually performed, were not so useful in formulating a sure preoperative diagnosis.

4'-Methylangelicins: new potential agents for the photochemotherapy of psoriasis.

Three derivatives of angelicin (1) [4'-methyl-, 4,4'-dimethyl-, and 4',5-dimethylangelicin (2a-c)] have been prepared with the aim of obtaining new agents for the photochemotherapy of psoriasis. These compounds form a complex in the dark with DNA that shows an affinity for the macromolecule higher than that of the parent angelicin (1). A correlation between their octanol/water partition coefficients and the association constants of the complexes has been observed. Compounds 2a-c photobind to DNA to a much higher extent than 1 and also more effectively than 8-methoxypsoralen (8-MOP), taken as reference compound. When activated with UV-A, the three compounds strongly inactivate T2 phage and inhibit epidermal DNA synthesis in mice. Moreover, they show a mutagenic activity markedly lower than that of 8-methoxypsoralen on Escherichia coli wild-type strain. Due to its lack of skin phototoxicity, its low mutagenic activity, and its antiproliferative activity, 2c was chosen for clinical evaluation. It proved to be effective in clearing psoriasis in two patients.

[Urologic complications in kidney transplants: experience in 274 transplants].

The urological complications after a renal transplantation still represent an event anything but rare, ranging, according to the different statistics, from 0.9% up to 23%, with a mortality between 0 and 25%. In this work done by the Verona Centre the experience on 274 transplantations is reported. The urological complications weighed with 6.2% and absence of mortality among the patients. The importance of the prevention and precocious diagnosis is confirmed.

[Indications and technic of percutaneous external biliary drainage].

After focusing the high surgical morbidity and mortality of icteric patients, the Authors describe their technique of insertion of percutaneous bile drainage after percutaneous transhepatic cholangiography. They insert drainage via the epigastric region, usually in the left hepatic duct. One case is described where the Authors associated percutaneous transhepatic drainage to regional chemotherapy through the catheter used for bile drainage. After for cycles of chemotherapy with 5-FU both intravenously and in the catheter, the Authors obtained the patency of the main bile duct which was previously obstructed by a methastases of stomach cancer.

[Current data on transhepatic percutaneous cholangiography in the differential diagnosis of jaundice].

The authors stress the actuality of percutaneous transhepatic cholangiography (P.T.C.) in differential diagnosis of jaundice, for absence of complications, low cost, simplicity of execution, and high percent of success. They derive their technique by Okuda et al., with some proper variations. Particular stress is placed on the decompression of biliary tree before and after injection of contrast medium (M.D.C.). Results obtained coincide with those of other authors.

Uselessness of thermography for diagnosis and follow-up of cutaneous malignant melanoma.

Thermography is useless for diagnosis of cutaneous malignant melanomas (CMM). In fact, false negative thermograms (29.9%) are much more numerous than clinically suspicious cases. Thermography is useless for follow-up of CMM. False-negative and false-positive thermograms of metastatic lymph nodes, subcutaneous nodules and removal site of CMM are much too numerous.

[Outcome research: rationales and objectives].

Outcome research measures the clinical, economic and humanistic outcomes of pharmacological therapies on patients suffering from different diseases. Outcome research can be applied either to phase II and III clinical trials to assess new drugs for registration or to already marketed drugs to assess their real value when used in clinical practice in a large population of patients. Oncology can be a major field of application because there is a large amount of new treatments put on the market, often without demonstration of significant improvement in survival or Quality of Life but with higher prices than the old molecules. Patients and disease specific outcomes have been identified for cancer by a Working Group set up by the American Society of Clinical Oncology, with the former being defined as more critical to establish the value of new treatments. Survival, drug toxicity and impact on Quality of Life are the most important patient's outcomes to consider before recommending anti-cancer therapies for use in clinical practice. The present paper will describe the outcomes in oncology and will deal with the transferability to clinical practice of the results of clinical trials.
