[Spigelian hernia: anatomo-clinical considerations]. / L'ernia di Spigelio. Considerazioni anatomo-cliniche.

Two cases of Spigelian hernia are reported. Starting from the analysis of these cases, some observations about the anatomy, the etiology, clinic, diagnostic methods and the best therapeutic choices now available for this uncommon pathology are presented.

[The use of prosthesis material in emergency surgery. Comments on a clinical case]. / L'utilizzazione di materiale protesico in chirurgia d'urgenza. Considerazioni su di una osservazione clinica.

The authors briefly report the case of a patient in whom a double Mersilene graft was used to repair a strangulated umbilical hernia. This report is interesting for various reasons. Firstly, the fact that surgery was performed under emergency conditions and secondly, the position of the graft, which was certainly not ideal--even if obligatory owing to the circumstances under which the operation was performed--in the abdominal wall. In spite of the successful results obtained, the authors feel that graft should preferably be used in elective surgery in which additional operations are not required which may further contaminate the operating field. In particular, special attention should be paid to graft position in relation to the various layers of the abdominal wall.

[Ionizing irradiation as a risk factor in thyroid cancer. A case report]. / Le radiazioni ionizzanti come fattore di rischio nel cancro della tiroide. Osservazione di un caso clinico.

The authors report a case of thyroid cancer which developed in a patient with a history of childhood therapeutic irradiation to the head for hemangioma. They confirm the importance of radiation as a risk factor for thyroid cancer and suggest some guidelines for the management and therapy of these particular neoplasms.

[Current trends in the treatment of voluminous eventrations]. / Moderni orientamenti nella terapia delle voluminose eventrazioni.

The authors speak about their experience on the giant incisional hernias. The surgical treatment of these lesions in not always easy, especially when exist some conditions such as the loss of parietal substance and the loss of residence right. In these cases the use of prosthetic meshes and the Goni Moreno's pneumoperitoneum are very helpful. The Authors point out how important is, for a successful treatment, as well as a correct surgical procedure and opportune pre and post operative management.

[Polyps of the gallbladder. Considerations on their real clinical significance]. / I "polipi" della colecisti. Considerazioni sul loro reale significato clinico.

The authors review all the cases of polyps of the gallbladder observed during the period 1964 to 1992 at the Institutes of Pathology and General Surgery at the University of Florence. On the basis of their experience, the authors affirm that these phenomena always cause more or less evident, even if not specific clinical symptoms; moreover, since they are considered high-risk lesions for the onset of malignant tumours, the authors emphasize the need for cholecystectomy in all cases.

[Anatomic and surgical considerations regarding the recurrent laryngeal nerve in thyroidectomy]. / Considerazioni anatomo-chirurgiche sul nervo laringeo ricorrente in corso di tiroidectomia.

The majority of surgeons view the preliminary identification of the recurrent laryngeal nerve (RLN) as an essential stage in thyroidectomy in order to preserve thyroid integrity. This conviction is based on the fact that the anatomical relations of the recurrent nerve during the cervical tract with adjacent structures are highly variable. The preparation of the RLN in a series of 42 thyroidectomies performed by the 1st Department of Pathological Surgery of the University of Florence confirmed this variability above all with regard to relations with the trachea, Berry's ligament and the branches of the lower thyroid artery. As a result, it is justified to consider the identification and preliminary preparation of the RLN on both sides as a fundamental and unavoidable stage in thyroidectomy.

[Diverticular disease of the vermiform appendix. Anatomo-clinical observations]. / La malattia diverticolare dell'appendice vermiforme. Osservazioni anatomo-cliniche.

The authors describe a case of diverticular disease of the appendix. The diagnosis is intraoperative and histological while therapy is based on surgical treatment. The authors seem to be favorable to surgical treatment in case of diverticulosis of the appendix in order to avoid dangerous complications.

[Progressive pneumoperitoneum in the surgical treatment of conspicuous ventral hernias. Importance of the procedure to restore a good respiratory function]. / Il pneumoperitoneo progressivo nella chirurgia delle ernie ventrali di ragguardevoli dimensioni. Importanza del procedimento per ristabilire una buona funzionalità respiratoria.

A recent clinical report regarding a patient with a voluminous laparocele treated using progressive pneumoperitoneum justifies this short paper on the use of this method as a preparatory act to reparative surgery. The paper emphasises the undoubted advantages deriving from the use of this technique, especially in the case of those subjects with a particularly poor respiratory function secondary to hernia.

[Pneumoperitoneum in preparation for surgery of large ventral hernia]. / Il pneumo-peritoneo nella preparazione agli interventi dei grandi laparoceli.

Reparative surgery of ventral hernia may be relatively simple or, on the other hand, the surgeon may be confronted with a number of tactical and technical problems. Many of these are caused by the "loss of the right of domicile". In order to avoid this particular condition it is useful to resort to preoperative pneumoperitoneum. This method entails the gradual and progressive introduction of air into the peritoneal cavity. In this way abdominal capacity is increased and it is therefore possible to re-insert all the viscera into their natural cavities avoiding all the harmful consequences for respiratory and cardio-circulatory organs following forced replacement. Preoperative pneumo-peritoneum is a relatively well consolidated surgical technique in large scale eventration. The methods is simple to perform and has a low incidence of complications.

[The use of interferon-beta in the treatment of essential mixed cryoglobulinemia]. / Impiego dell'interferone beta nel trattamento della crioglobulinemia mista essenziale.

The authors report two cases of essential mixed cryoglobulinemia (EMC) manifested by purpura, fatigue and arthralgia. After a corticosteroid treatment which proved a complete failure, beta-interferon therapy was started. This caused rapid improvement of the clinical picture without relevant side effects.

[Progressive pneumoperitoneum in the preparation for surgical intervention for voluminous ventral hernias]. / Il pneumoperitoneo progressivo nella preparazione all'intervento chirurgico per voluminose ernie ventrali.

The paper report three patients suffering from voluminous ventral hernias who were treated using progressive pneumoperitoneum as a preparative method prior to reparative surgery. On the basis of the results obtained, the authors sustain the rationality, safety and efficacy of the procedure, in particular given its ability to reestablish good respiratory and circulatory function in those cases where the latter were severely affected by hernia. Since this method needs a longer application time and therefore involves a greater economic burden, pneumoperitoneum should probably be reserved for selected cases, and alternative techniques should be used in patients where hernia is more easily resolved.
