[An acute pseudo-cholecystitis].

In an emergency department, many patients were admitted with abdominal pain. The problem is to made the right diagnosis between an acute abdomen that must be manage by a medical approach and an acute abdomen with immediate surgical treatment. We present the case of a 44 year-old man admitted in our emergency department with clinical signs of acute cholecystitis. After a new interrogation and the inadequacy of the diagnostic procedures a lead intoxication treated by a medical approach was diagnosed.

Metastatic involvement of the humerus: a retrospective study of 51 cases.

The authors performed a retrospective review of 53 patients with 56 completed or impending pathological fractures of the humerus. Sixteen cases were treated with a proximal and one with a distal humeral prosthesis, 38 with an intramedullary device with cement and one with plate fixation. Forty-eight patients with 51 humeral metastases were available to follow-up. No or only occasional pain was observed in 92% of the operated extremities and adequate postoperative function in 90%. No major complications occurred, except one rod migration.

[Isolated pelvic metastasis of thyroid cancer].

Thyroid cancer rarely metastasizes to the pelvis. We report a case where the metastasis was found two years before the thyroid cancer. Treatment included initial surgery with resection of the metastatic tumor and reconstruction of the acetabulum with bone cement, and secondly total thyroidectomy, node dissection and I131. Surgical treatment of locoregional recurrence had no influence on the clinical course leading to the patient's death. Early diagnosis of unique metastasis of a thyroid cancer is important in terms of prognosis and quality of life. This case is exceptional due to the unique bone metastasis and treatment options for acetabular metastases. Therapeutic options should be adapted according to algorithms reported in the literature.

[Prognostic factors in epidermoid carcinoma of the mobile tongue classified as T1-T2].

INTRODUCTION: Our aim was to evaluate the results and the prognosis of squamous cell carcinoma of the mobile part of the tongue stage T1-T2 treated by surgery and radiotherapy at the Institute Jules Bordet from January 1950 to 31th December 1993. METHODS: According to the classification TNM (UICC 1978) 165 consecutive patients classified as follow: 73 T1No (stage I), 64 T2No (stage II), 7 T1N1 and 20 T2N1 (stage III) and 1 patient T2N2 (stage IV). All patients underwent surgery beforehand. 136 patients received additional brachytherapy. RESULTS: In this study were included 117 men and 48 women with an average age of 60 years. The rate of relapse on the primary tumoral site amounted to 16,4% and the residual relapse to 40%. The survival note without relapse was evaluated respectively at 3 years in 67% of the tumours T1 (against 28% for the T2), at 5 years for 59% for tumours T1 (against 26% for T2). From the clinical point of view the survival rate without relapse was of 5 years for 61% of stage I, 29% of stage II and 24% of stage III. A more extensive investigation shows the statistic influence, such as age (p<0.004), size of the tumour (p<0.007) and its shape (p<0.0007) on the total survive rate. The state of the nodes (p<0.02) and the safety margins (p<0.04) are statistically less associated. The survival rate with no relapse according to a study considering statistical factors, is significantly influenced by the size (p<0.0002) and age (p<0.0003). CONCLUSION: T1-T2 stages of the mobile tongue are characterized by a limited local spread but a more regional spread and diversified therapeutic approach with prognostic factors influencing the survival rate without forgetting the part played by the TNM classification.

Sentinel lymph node evaluation in squamous cell carcinoma of the head and neck cancer: preliminary results.

INTRODUCTION: Sentinel lymph node biopsy is a new technique in staging the clinically NO neck. Tumour spread to the neck is the most important prognostic factor in head and neck squamous cell carcinoma (HNSCC). MATERIAL AND METHODS: Patients with histologically confirmed HNSCC, with no clinical and no radiological (CT or MRI) evidence of cervical lymph node involvement were eligible for this prospective study. The lymph node mapping was performed by preoperative lymphoscintigraphy and intraoperative use of hand-held gamma probe. Four injections (with Tc 99m-labeled nanocolloids) were performed around the primary tumour. The SLN, as indicated by dynamic scintigraphy and the neck dissection specimen, were sent separately for histological analysis. The presence of occult metastasis in the SLN and in the neck dissection specimen were compared. RESULTS: Ten consecutive patients (8 males ; 2 females) with a mean age of 61 years (range 47 to 74 years) were prospectively entered into the study. The primary tumour was located on the oral tongue in 4 cases, in the floor of the mouth in 5 cases and in the oropharynx in 1 case. Primary tumours were staged T2 in nine cases, one tumour was staged T1 according to UICC 1997. All the tumours were clinically staged cN0 by palpation and computed tomography (or MRI). Lymphoscintigraphy was performed and revealed a SLN in all cases. The sentinel node biopsy technique permitted an upstaging of the clinically cN0 neck in 3/10 cases. The SLN technique was false negative in one patient with a skip metastasis. CONCLUSION: SLN evaluation in HNSCC is feasible and provides a highly accurate staging of NO necks in oral and oropharyngeal carcinomas.
