[Tumoral form of abdominal actinomycosis: a retrospective case series of seven patients]. / Actinomycoses abdominales à forme tumorale : une série rétrospective de sept observations.

PURPOSE: Abdominal actinomycosis is an uncommon chronic infectious disease due to Actinomyces, a Gram-positive bacteria. This saprophytic bacteria of digestive tract and genital mucosa can occasionally become pathogenic mimicking a digestive neoplasia. The aim of this study was to underline diagnostic features of abdominal actinomycosis and to summarize data about clinical, diagnostic and therapeutic approach of this type of infection. PATIENTS: From January 1995 to December 2007, retrospective data concerning patients with abdominal actinomycosis who were followed-up in the University Hospital Sahloul (Sousse, Tunisia) were analysed. RESULTS: Seven patients with abdominal actinomycosis were identified during the study period. All presented with an abdominal mass. The diagnosis of actinomycosis was obtained after surgical resection in all cases. The histological study permitted the diagnosis in six cases, and the surgical samples grew up Actinomyces in two patients. For the five patients who received prolonged and adapted antibiotic therapy, a favourable outcome was observed. CONCLUSION: Actinomycosis must be included in the differential diagnosis of invasive abdominal lesions with "malignant appearance".

[Prognostic factors and survival of metastatic colorectal cancer in the Sousse University Hospital (Tunisia): comparative study of two treatment period of 200 patients]. / Facteurs pronostiques et survie des cancers colorectaux métastatiques au CHU de Sousse (Tunisie): etude comparative de deux périodes de traitement de 200 patients.

UNLABELLED: Between 1994 and 2005, 200 patients with metastatic colo-rectal cancers were treated in the Sousse CHU (Tunisia), we analysed two groups of patients, the group 1 was treated in the period after 1999 (N = 64), the group 2 was treated in the period between 1999 and 2005 (N = 136). PATIENTS AND METHODS: Mean age of the patients was 50 years, localisation of metastases was liver in 67.3% of cases, 23% of patients had multiple metastases, 44% of cases developed metastases after a median period of 11.4 months. All patients had received first line of chemotherapy, the regimen of chemotherapy was in the group 1, Fufol in the majority of cases (76%), the regimen of chemotherapy was in the group 2, simplified LV5FU2 associated to irinotecan in the majority of cases (83%), 28% of all patients received second line of chemotherapy. RESULTS: The median survival was 13.8 months in the group 1 and 19 months in the group 2. Overall survival rates at 2 years were 35% and 42% (p = 0.02) in group 1 and 2, respectively. Prognostic factors for a better survival using univariate analysis were: normal ACE (P < 0.01), normal liver analysis (P < 0.001), response after 3 cycles of chemotherapy (P < 0.0005), resection of liver metastases (P < 0.05). The multivariate analysis (cox model) revealed only one independent factor: radiologic response after 3 cycles of chemotherapy (P < 0.03). CONCLUSION: The prognostic of patients with metastatic disease is poor, although palliative chemotherapy after the recent advances and the use of new drugs have been shown to be able to prolong survival and to improve the quality of life over best supportive care. This study report amelioration of prognostic and survival of metastatic colorectal cancers in Tunisia.

[Anal metastasis of colonic adenocarcinoma?]. / Métastase anale d'un adénocarcinome du côlon?

Two cases of sigmoid and anal adenocarcinoma are reported. The two patients were treated by abdominoperineal resection of the rectum and resection of the sigmoid colon. The relationship between colonic adenocarcinoma and anal adenocarcinoma is not obvious but possible. The various mechanisms of tumoral spread are discussed and the most frequent mechanism seems to be cellular exfoliation.

[Conservative treatment of the spleen. Report of 50 cases]. / Le traitement conservateur de la rate. A propos de cinquante cas.

From 1983 to 1989, 50 patients have been treated by spleen conservation. Traumatism was iatrogenic in 9 cases, caused by public highway accidents in 31 cases, domestic accident in 9 cases and penetrating trauma in one case. Spleen conservation includes: 26 partial splenectomies, 11 cauterisations, 10 sutures, 5 auto-transplantations, and 3 abstensions after laparotomy and little spleen trauma. Three deaths were observed secondary to cerebral trauma, and two complications have been seen: one during the operative solved by total splenectomy, and one rebleeding after splenorraphy, reoperated and splenectomy was performed with good evolution. The follow-up of partial splenectomy showed that splenic remnant keeps an epuration activity.
