Fatal miliary tuberculosis following treatment with Infliximab

We report the first Tunisian case of miliary tuberculosis in a patient who received Infliximab for Crohn's disease with uretrorectal and ano-perineal fistula developed 4 weeks after the start of treatment. We suggest that diagnosis of latent tuberculosis infection is important before treatment with Infliximab is initiated and that antituberculous medication must be prescribed immediately in case of occurrence of unexplained fever after treatment with Infliximab.     

Jaccoud arthropathy and pyrophosphate arthropathy: a rare association

Jaccoud's arthropathy (JA) is a chronic deformity affecting hands and feet, which are voluntarily correctable by the patients. JA was usually reported in association with rheumatic fever and systemic lupus erythematosus. We describe an exceptional association between a pyrophosphate arthropathy and JA of the hands. It is a 48-year-old woman, having a 13 years history of polyarthritis involving shoulders, elbows, hips and knees, and 4 years after, a progressive unlar deviation of the fingers of the hands. Calcium pyrophosphate dihydrate crystals were identified in the synovial knee biopsy. Hands x-rays as RMI don't identify erosions and confirmed the JA.     

Mechanical ventilation in intensive care units: indications, modalities and complications. Results of a prospective multicenter survey in Tunisia

The survey was performed during the month of March 1998 and concerned 9 ICUs located in teaching hospitals. To be included each ICU had to MV for more than 12 hours were included in the study and had a 28 day follow-up in the ICU or until hospital discharge. Collected parameters were indications of MV, modalities of MV and of weaning, complication and outcome at hospital discharge. Assist-control ventilation was the most used ventilation modality (69.8%). Weaning of MV was performed in 63% of the study patients and was based on a once-a-day attempt of spontaneous breathing through a T-piece (59.5%) and a combination of intermittent mandatory ventilation with pressure support (IMV-PS: 27%) or pressure support alone (11.2%). Mean length of hospital stay was 19.7 +/- 15.9 days of which 11.6 days were spent in the ICU. Fifty nine patients (54%) were alive at discharge form the ICU of whom 4 ultimately died during their hospital stay. MV practice as well as ICU facilities are not homogenous in Tunisia. Recommendations and guidelines should be built in order to standardize MV practice in Tunisia.     

Acute pancreatitis due to a metallic foreign body

We report a case of acute pancreatitis caused by a metallic foreign body located in the pancreatic head in a 38-Year-old woman. Only 15 cases of acute pancreatitis due to foreign bodies, metallic in five cases, have been published to date. In our case, diagnosis was established by the computed tomography scan. The patient declined surgery.     

Prevention of central venous line-related thrombosis by continuous infusion of low-dose unfractionated heparin, in patients with haemato-oncological disease. A randomized controlled trial

We have conducted a prospective randomized controlled trial to evaluate the role of low-dose unfractionated heparin prophylaxis in preventing central venous line-related thrombosis in patients with haemato-oncological disease. Patients were randomly assigned to receive either prophylactic intravenous unfractionated heparin (continuous infusion of 100 IU/kg/daily) or 50 ml/daily of normal saline solution as a continuous infusion. CVLs were externalized, non tunneled, double lumen catheters. All CVLs were placed percutaneously by the same physician in the subclavian vein. Upper limb veins were systematically examined by ultrasonography just before, or <24 hours after, catheter removal, and in case of clinical signs of thrombosis. One hundred and twenty-eight CVLs were inserted. Catheter-related thrombosis occurred in 1.5% of the catheters inserted in patients of the heparin group, and in 12.6% in the control group (p = 0.03). No other risk factors were found for the development of catheter-related thrombosis. Two and three patients experienced severe bleeding in the heparin group, and in the control group, respectively (p = 0.18). There were no other side-effects clearly ascribable to the use of unfractionated heparin. This is the first prospective, randomized study, which shows that low-dose of unfractionated heparin is safe and effective to prevent catheter-related thrombosis in patients with haemato-oncological disease.     

Effect of triple antiretroviral therapy on Tunisian AIDS profile: study of 139 cases

We report a retrospective study to estimate highly active antiretroviral therapy (HAART) effect in 139 HIV infected patients. Four criteria are studied: prevalence of opportunistic infections, CD4 cell count evolution, viral load progression and mortality. Gastrointestinal side effects are the most common clinical adverse reaction (61.1 percent), and hematological side effects are the most common biological adverse reaction (61.2 percent). During the 22.8 months (3 months to 6 years) follow-up average period, CD4 cell counts remained above 500 per cubic millimeter in only 25.8 percent of cases, while 63.5 percent of patients had a viral load below 400 copies per milliliter. During the study on patients receiving HAART, opportunistic infections appeared in 17.3 percent of cases (24 cases) and mortality in 6.4 percent of cases.     

Anti‐inflammatory and antiproliferative activities of crude extract and its fractions of the defensive secretion from the Mediterranean sponge,Spongia officinalis

The fact that conventional and newly emerging treatment procedures like chemotherapy, catalytic therapy, photodynamic therapy, and radiotherapy have not succeeded in reversing the outcome of many cancers alternative treatment options has been explored. This study documents the identification of component(s) from the Mediterranean sponge, Spongia officinalis that have anti‐inflammatory and antiproliferative activities. In the present study we investigated the efficacy of a crude extract and its semi‐purified fractions (F1–F3) of the defensive secretion from Spongia officinalis for in vivo anti‐inflammatory activity using the carrageenan‐induced paw edema assay in rats and their in vitro antiproliferative effects against three human cancer cell lines (A549, lung cell carcinoma; HCT15, colon cell carcinoma; and MCF7, breast adenocarcinoma). Among the series, the crude extract exhibited interesting anti‐inflammatory activity associated with significant growth and concentration‐related colony inhibitory effects against the three cell lines. The fractions F2 and F3 showed, respectively, interesting anti‐inflammatory and antiproliferative activities in a dose‐dependent manner. The purification and the determination of chemical structures of compounds of these active fractions are under investigation. Drug Dev Res 71: 412–418, 2010. © 2010 Wiley‐Liss, Inc.     

A predictive model for survival after in-hospital cardiopulmonary arrest

BACKGROUND: In-hospital cardiopulmonary resuscitation (CPR) has seen a steady increase in the application of technology and techniques since the introduction of closed cardiac massage in 1960. Despite this progress, there has not been a demonstrated improvement in survival rates after in-hospital cardiac arrest over the last 40 years. Identification of prognostic factors associated with survival after a resuscitation attempt can help physician decisions and patients' end-of-life choices in a pre-arrest situation. METHODS: Using an Utstein-based template we analyzed 219 consecutive adult attempted resuscitations in a large urban teaching hospital over a 3-year period. The main outcome measures were survival to discharge, 1 and 3 months. Backwards stepwise logistic regression was used to select baseline variables that predict survival at discharge, 1 and 3 months. RESULTS: Survival rates at discharge, 1 and 3 months were 15.1, 13.3, and 11.5%. Meaningful neurological status (cerebral performance score of 1) at discharge was achieved in 61% of survivors. Independent predictors of survival were: higher body-mass index (BMI), presence of chronic renal insufficiency (CRI), respiratory arrest, ventricular tachycardia/fibrillation (VT/VF) as initial rhythm and arrest early during the hospital stay. A risk model based on these variables demonstrated a significant fit between predicted and observed survival at discharge with goodness of fit test P-value of 0.87. CONCLUSIONS: Survival after in-hospital cardiopulmonary arrest is poor and can be estimated by using clinical variables. If validated in a large prospective trial, this score could help physicians in attempting resuscitation, patients and families in making end-of-life decisions and hospitals in resource allocation.
