The partial DNA sequences of the 18S rRNA gene of Babesia canis and the 16S rRNA gene of Ehrlichia canis detected in dogs from Ribeirão Preto, Brazil, were compared to sequences from other strains deposited in GenBank. The E. canis strain circulating in Ribeirão Preto is identical to other strains previously detected in the region, whereas the subspecies Babesia canis vogeli is the main Babesia strain circulating in dogs from Ribeirão Preto.

The Italian Registry of Laparoscopic Surgery of the Spleen (IRLSS) A retrospective review of 379 patients undergoing laparoscopic splenectomy.

In December 2000, the Italian Registry of Laparoscopic Surgery of the Spleen (IRLSS) was formally launched under the auspices of the Italian Society for Endoscopic Surgery and New Technologies (SICE). The aim of this multicentre study was to analyse various aspects of the treatment that are still under discussion, such as the extension of the laparoscopic indications in cases of malignancy, independently of the associated splenomegaly, patient selection and operative techniques. A retrospective review of 379 patients undergoing laparoscopic splenectomy for haematological diseases from February 1, 1993, to September 15, 2005, was conducted.

Intestinal occlusion secondary to Morgagni-Larrey's herniation in an adult. Case report and analysis of the literature.

Morgagni-Larrey's hernias are congenital diaphragmatic hernias, rarely observed and generally identified accidentally due to the lack of symptoms. The authors report a case of intestinal occlusion secondary to Morgagni-Larrey herniation in an adult recently observed and underline the aetiopathogenic aspects, the diagnostic tools and the clinical pattern. They suggest to consider surgical repair as a choice of treatment, also for asymptomatic patients.

Lymphatic mapping for the dissection of the sentinel node in the treatment of breast carcinoma.

The Authors present the preliminary results of a study aimed at verifying the effectiveness of lymphatic mapping for the dissection of the sentinel lymph node in the treatment of breast carcinoma. The lymphoscintigraphy method was used in the study performed on 24 patients to evidence the sentinel lymph node. The sentinel lymph node was identified in 23/24 patients (95,8%), with 100% accuracy, negative predictions were 100% (21/21).

[The indications for prophylactic colectomy in diverticular disease].

Still controversial is the role of surgery in symptomatic colon diverticular disease, outside the major complications. In such circumstances the surgeon has to comfort himself with diagnostic and then with operative choices, and also the preventive colectomy has to be considered. To make a correct decision very important is the global evaluation of the patient, for age, sex life habits, other existing pathologies, general condition.

Objective: A prospective study was performed in order to compare results obtained in the treatment of early and/or limited primary varicose veins of the lower limbs using two different procedures: external valvuloplasty and high ligation or disconnection of the sapheno-femoral junction.

Materials And Methods: 116 limbs (113 patients) were selected. 57 with normal cusps in dilated valves were subjected to external valvuloplasty with Silicone prosthesis under Doppler control (intraoperative angioscopy in 16 cases); 59 limbs were subjected to high ligation or disconnection of the junction; 57 limbs out of 116 were subjected to complementary procedures.

Seasonal variations in the rupture of abdominal aortic aneurysms.

From 1982 to 1994, 54 patients (47 men; mean age 72 years) were referred to the Hospital of Ferrara, Italy for spontaneous rupture of abdominal aortic aneurysm. Sixteen died in the emergency department and 38 underwent urgent surgery. Day and month of onset of acute symptoms leading to urgent surgery were recorded.

[Contribution of a combination of alpha and beta benzopyrones, flavonoids and natural terpenes in the treatment of lymphedema of the lower limbs at the 2d stage of the surgical classification].

Hypothesis: To create a phlebolymphologic therapy in order: to activate venous system; to activate lymphatic system; to activate macrophagic system; to reduce the proteic lymphatic load.

Experimental: A study was performed on the use of an ideal phlebolymphological association (Tonka Beans, Gingko Biloba, Melilotus Officinalis) as a practical standpoint in the treatment of lymphedema of lower limbs in order to create an efficacious dose of Coumarin, Benzopyrones and Ginkolidi. CLINICAL: We investigated a population of 76 patients treated in an open-label study for six-eight months with a dosage of Coumarin 60 mg/daily + Gingko Biloba 40 mg/daily + Melilotus 40 mg/daily.

[Aneurysms of the popliteal artery. Our experience apropos of 37 cases].

The authors describe their experience concerning the surgical treatment of aneurysmatic pathology of the popliteal artery. This is the most frequent site for aneurysm after aortic aneurysm. Since 1979 to 1994, 26 patients, 21 men and 5 women (mean age 65.

Experimental study on protein transmission through the human muscle fascia: preliminary results and application theory in lymphedema.

The presence of proteins (albumin and globulins) in lymphedematous tissue not only gives rise to colloidosmotic pressure but also produces an electrostatic charge endowing the proteins with individual features and different migration rates. The working hypothesis of the experimental study is to transfer lymph proteins from the upper fascia accumulation area to a subfascial drainage area by subjecting them to an adequate difference in potential. A double chamber, variable volume system with separation wall able to contain a 1 cm square of muscle fascia, was designed and built; the aim of the apparatus was to reproduce the subcutaneus zone separated by the fascia interposition, from the muscle-vascular zone.

[Experimental study of postoperative lavage: standardization of the method].

Postoperative infections are an outstanding problem in a surgical department. We have been studying them from a clinical and experimental point of view has a long time. In this study we present a method standardisation of postoperative peritoneal lavage as prevention of surgical infections.

The spontaneous pneumothorax (pnx. s.) is a type of pathology with a high per cent of relapse so its aetiological treatment can't be done only with a pleural drainage.

Peritoneal cystic mesothelioma treated with minimally invasive approach.

A case of peritoneal cystic mesothelioma in a young woman was treated with a minimally invasive approach. The technique and a review of the literature are presented.

[Pleural drainage vs video-assisted minimally invasive surgery in the treatment of spontaneous pneumothorax. A retrospective study].

The most frequent cause of spontaneous pneumothorax is bleb's disease of the lung. Considering that, pnx s. has a remarkable bent for relapsing, we think that it's necessary an aggressive treatment to resolve it.

[Use of PGE1 in severe ischemia of the lower extremities. Clinical study].

Lower limb critical ischemia is a clinical condition typical of patients with severe chronic obstructive arterial disease (Fontaine's IIIb and IV degree). This condition often leads to amputation of the limb involved. The authors present to the use PGE1 in 50 patients with Fontaine's IIIb-IV degree chronic obstructive arterial disease of lower limbs in which the indication of amputation was done.

[Video-assisted mediastinoscopy: clinical uses].

The experience with video-assisted mediastinoscopy in 16 cases examined, is reported. Initially the classic mediastinoscopic device with the aid of an operative thoracoscopy was used. Starting from April 1994 the Authors used the video-assisted mediastinoscopy which, enlarging the surgical field, allows to improve the operative performance and may be a good aid for multiple teaching.

[Deep venous thrombosis and surgery. Assessment of the main risk factors].

Deep venous thrombosis is a quite frequent pathology with a high degree of morbidity and death-rate. Two are the main problems of this disease: the risk of pulmonary embolism and outcome of a post-thrombotic syndrome, leading patients to infirmity. The patients max exposed to the risk of deep venous thrombosis are the surgical ones: the authors, with a retrospective study on 480 surgical patients, examine the risk factors mostly related with the onset of deep venous thrombosis.

["Simulated walking" in the duplex evaluation of the venous system. The clinical and instrumental correlations].

The goals of non-invasive duplex vascular diagnosis of the venous system of the lower limbs are: 1) To make evaluation of the venous system during deambulation feasible under physiological, pathological and post-surgical or elastocompressive conditions. Moreover, any such evaluation must be achieved using a standardized, easy, highly reproducibly method which is inexpensive and utilizes the diagnostic instruments available. 2) To achieve detailed, selective localization of the valvular and parietal dysfunctions at the basis of any reflux pathology.

[Thoracic lymphadenectomy in video-assisted mini-invasive thoracic surgery. First experience].

The Authors report their experience in the thoracoscopic surgical treatment of neurovascular abnormalities of the upper extremities. The experience acquired in the last two years with mini-invasive video-assisted thoracic surgery of the pleura and lung forced the Authors to perform thoracic sympathectomy following the same approach. In this way 4 thoracic sympathectomies were performed in 3 patients.
