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.
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.
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.
The efficacy and tolerability of nimesulide and naproxen were compared in a randomised double-blind study of patients with pain and inflammation after haemorrhoidectomy. Both drugs appeared similarly effective in reducing pain and oedema and no adverse reaction was detected. These data extend the information on the anti-inflammatory and analgesic efficacy of nimesulide in the postoperative setting.
Twenty-four patients with Raynaud's phenomenon, without ARA criteria for classification, were examined, after clinical history, by means of esophageal manometry, combined gastric and esophageal pH-monitoring, endoscopy. The results showed in these patients a high incidence of esophageal motor abnormalities (66.6%), of gastroesophageal reflux (50%), and of duodenogastric reflux (45.8%).
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.
The Authors, before examining their case history, which includes 103 major and minor hepatic resections performed during the last decade, briefly show the surgical technique concerning hepatic ischaemia and the new technologies proposed to reduce the hematic loss during hepatic resections. The constant adoption of these techniques and the careful evaluation of some parameters concerning hepatic functionality allowed to decrease postoperative complications and mortality, which currently is around 5-10%. These data are confirmed by the Authors experience.
