Introduction. Thyroid cancer is the most common endocrine malignancy and accounts for almost 1% of human cancer. It is well known that the majority of cases occur in women in the middle decades of life. Thyroid cancer is a relatively rare disease; on the other hand clinically apparent thyroid nodules are present in 4-7% of the adult population. Most thyroid nodules are not malignant, with reported malignancy rates from 3-12%. It is important for the surgeon to know beforehand the diagnosis of malignancy, in order to perform a more radical operation on the thyroid gland. Patients and Methods. In our study we have analyzed the preoperative clinical data of 84 patients operated in the First Clinic of General Surgery, UHC “Mother Theresa” in Tirana; all with a positive histopathologic diagnosis of thyroid cancer. The data comprised age, sex, age distribution, blood group, time-lapse from the first endocrinologic visit, clinical examination, signs and symptoms, imaging, functional tests, preoperative FNA, admission diagnosis, associated diseases and preoperative treatment. Results. From the study emerged that only 9,3% of these patients were diagnosed preoperatively as thyroid cancer. Another related problem is the low percentage of preoperative FNA – only 22%. Among the signs and symptoms related to thyroid cancer we found that 40 and 33% of these patient presented dyspnea and dysphagia, respectively. The physical examination revealed apparent nodular growth of the thyroid gland in 81% and nodular hard consistency in 79% of cases. The proper endocrinologist consultation lacked in 23% of cases. Conclusion. In our opinion, close collaboration between endocrinologists and surgeons in a multidisciplinary frame is the key to correct preoperative thyroid cancer diagnosis and optimal treatment.

ntroduction. Trauma is the most common cause of death and disability among patients during the first four decades of life. Abdominal trauma is reported to be the 3rd most common injured region. Clinical examination may be unreliable in the evaluation of these patients especially in the presence of associated injuries. Therefore the use of diagnostic tools is essential in the management of the injured patient with abdominal trauma and additional injuries. Patients and Methods. During 1 year period from December 2010 to November 2011 we recorded the patients that presented to the emergency department of our hospital and were found to suffer from intra-abdominal injuries. These patients were divided in two groups depending on whether they had additional comorbid injuries or not. Several parameters were recorded and compared between the two groups, such as mechanism of injury, general status and hemodynamic stability of the patient on presentation, physical examination, use of imaging modalities and concomitant findings, need for surgical intervention and mortality rates. Furthermore the discrepancy between physical findings and final diagnosis after the use of diagnostic adjuncts is reported. Results. We recorded 31 patients with abdominal trauma. 13 (42%) patients were found to suffer from abdominal trauma and associated injuries (Group I), whereas 18 (58%) presented with abdominal trauma alone (Group II). The patients of the first group presented hemodynamic instability in 38% of cases while the patients of the second in 22% of cases. Reduced consciousness was present in 38% in group I versus 17% in group II. Signs of abdominal injury during clinical examination were present in only 15% in group I versus 72% in group II that represented a remarkable difference between the two groups. Conservative treatment was possible in 15% of patients with additional injuries and in 22% of patients with abdominal injury alone. In group I there were two deaths whereas in group II all patients survived. Conclusion. In patients with abdominal trauma, associated injuries seem to add to the severity of injury and indicate a worse prognosis. Clinical examination is unreliable and misleading in the majority of these patients and the use of diagnostic tools cannot be overemphasized.

Objectives: To describe the diagnosis and treatment of a severely ill patient presenting with thrombotic microangiopathy (TMA) of unknown cause. Case presentation: An adult female presented to intensive care with abdominal pain and haemorrhagic shock, requiring reanimation. Results: Features of TMA were present, but initial plasma exchange was ineffective. Treatment with the anti-C5 antibody, eculizumab, improved laboratory parameters and organ function, albeit slowly. Eculizumab remains effective and well tolerated after 30 months of treatment. Conclusion: This case demonstrates the complexities and importance of early identification of atypical haemolytic uraemic syndrome in patients presenting with TMA.
