Efficacy of desmopressin as surgical prophylaxis in patients with acquired von Willebrand disease undergoing thyroid surgery.

Coagulation abnormalities may occur in patients with thyroid diseases. We report on 14 patients undergoing thyroid surgery for a thyroid disease with an alteration of coagulation parameters resembling von Willebrand disease. Subcutaneous desmopressin was first tested and then used successfully in these patients as surgical prophylaxis, with no side-effects or bleeding complications during or after surgery. This study highlights the need for coagulation studies in patients with thyroid diseases undergoing thyroid surgery. Subcutaneous desmopressin may be used in these patients in order to prevent a surgically related bleeding risk.

[Appendiceal mucocele associated with colonic neoplasm. Report of 2 cases and review of the literature]. / Mucocele appendicolare associato a neoplasia del colon. Presentazione di due casi e revisione della letteratura.

Appendiceal mucocele is a rare entity frequently associated with colorectal cancer. We report two cases of mucocele associated with colorectal tumours. The first case (male, 64 yrs) is an appendiceal mucinous cystadenoma found incidentally during surgery for colon cancer. There is no evidence of disease after a 4-year follow-up. The second case (male, 66 yrs) is a mucocele associated with mucosal hyperplasia that was found during surgery for acute appendicitis with a periappendicular abscess. Endoscopic follow-up showed a rectal adenocarcinoma that was initially treated with local excision with T.E.M.. Examination of the pathology specimen documented vascular invasion and the patient underwent curative colorectal resection. The preoperative radiological and endoscopic diagnostic procedures and the current therapeutic approaches described in the literature are reviewed. The relevance of the association between appendiceal mucocele and colorectal cancer is emphasized. Thorough investigation of the colorectal tract is recommended after diagnosing an appendiceal mucocele.

[Bilateral pheochromocytoma associated with duodeno-jejunal GIST in patient with von Recklinghausen disease: report of a clinical case]. / Feocromocitoma bilaterale associato a GIST duodeno-digiunale in paziente affetto da malattia di von Recklinghausen: presentazione di un caso clinico.

The authors present the case of a 60-year-old male patient suffering from von Recklinghausen's disease (neurofibromatosis type I, NF1) with bilateral pheochromocytoma and occasional intraoperative reports of duodenojejunal GIST (GastroIntestinal Stromal Tumour). Through a review of the literature the authors analyze the frequency and the features of bilateral pheochromocytoma and its rare histological variant, the so-called composite pheochromocytoma, characterized by the combination of pheochromocytoma and ganglioneuroma or ganglioneuro-blastoma. Bilaterality of pheochromocytoma is more frequent in patients with familiarity for pheochromocytoma without NF1. Composite pheochromocytoma accounts for about 3% of total pheochromocytomas. In addition, the authors summarize the present knowledge about gastrointestinal stromal tumours and investigate the possible association between them and NF1 or pheochromocytoma, concluding that any such association is purely casual, while confirming the well known, genetically determined association between NF1 and pheochromocytoma.

[Endometriosis of umbilical cicatrix: a clinical case]. / Endometriosi della cicatrice ombelicale: un caso clinico.

The Authors report a case of umbilical endometriosis in a 46-year-old patient. The woman came in for observation describing acute pain in the vicinity of the umbilical scar. The pain was occasional at first and then became steady and increased at the time of menstruation. Medical examination revealed a left paraumbilical nodule, measuring 1 cm in diameter. The patient underwent surgical treatment: the nodule was excised and the subsequent histological examination was diagnostic for umbilical endometriosis. The surgical excision was effective: at follow-up 3 months later, there was no recurrence and the patient was in good general condition.

[Fournier's gangrene in a patient with Hodgkin's disease: a clinical case]. / Gangrena di Fournier in paziente con morbo di Hodgking: un caso clinico.

The authors report a case of Fournier's gangrene in a 54-year-old patient subjected 6 days earlier to chemotherapy for mediastinal Hodgkin's disease. The patient had fever and reported the onset of worsening pain and heat sensations in the inguinal, perineal and scrotal areas. Objectively, there was local oedema followed by the onset of crepitation. The patient had a very low white blood cell count (900/cu.mm). The Patient underwent emergency surgery with multiple, communicating incisions in the inguinal, perineal and scrotal areas, with the removal of necrotic tissue and daily washing with physiological solution and 12% H2O2. He also received antibiotic treatment with metronidazole and gentamicin and 5 cycles of high-pressure oxygen therapy, with disappearance of pain and fever and good local tissue repair.
