Cavopulmonary shunts: apropos of 40 observations

Fourty patients with univentricular heart, underwent a cavopulmonary shunt procedure. The majority have an excellent hemodynamic status with ventricular end diastolic pressure > 12 mmHg and a mean pulmonary artery pressure > 15 mmHg. However, 11 patients have ventricular dysfunction, 9 have an incompetent systemic atrio-ventricular valve and 6 have mean pulmonary artery pressure > 15 mmHg. The pulmonary arteries were of a good size in all cases with a Nakata index > 100 mm2/m2. Cavopulmonary connections are satisfactory palliative procedures in the treatment of univentricular cardiac disease.     

Evaluation of the sensitivity of Moroccans to shrimp tropomyosin and effect of heating and enzymatic treatments

The aim of this work was to evaluate the IgE-sensitivity to shrimp tropomyosin (ST) in a Moroccan population from Fez region, and then to study the effect of temperature and enzymatic digestion on the allergenicity of ST. This work was conducted with a questionnaire completed by a sera-bank, obtained from 500 patients recruited from Fez Hospitals. Their sera were analyzed for specific IgE-sensitivity to ST. From questionnaire, 9.8% reported allergy to fish and shellfish where shrimp was one of the most common species causing allergy in patients. Evaluation of specific IgE showed that 10.2% of patients present higher values. Further indirect ELISA and Dot-blot results indicated that ST showed a decrease in the human IgE binding under heating or pepsin hydrolysis. These results demonstrate that this population was sensitive to ST and the sensitivity could be reduced by heating and more where it was digested by pepsin.     

Assessment of executive functions in children and adolescents with acquired brain injury (ABI) using a novel complex multi-tasking computerised task: The Jansari assessment of Executive Functions for Children (JEF-C©)

ABSTRACT

Objectives: The Jansari assessment of Executive Functions for Children (JEF-C^©) is a new non-immersive computerised assessment of executive functions. The objectives of the study were to test the feasibility and validity of JEF-C^© in children and adolescents with acquired brain injury (ABI).

Methods: Twenty-nine patients with ABI aged 10–18 years and 30 age-and gender-matched controls were tested. Participants performed JEF-C^©, Wechsler Abbreviated Scale of Intelligence (WASI) and the Behavioural Assessment of the Dysexecutive Syndrome for Children (BADS-C), while parents completed the Behaviour Rating Inventory of Executive Function (BRIEF) questionnaire.

Results: The JEF-C^© task proved feasible in patients with ABI. The internal consistency was medium (Cronbach’s alpha?=?0.62 and significant intercorrelations between individual JEF-C^© constructs). Patients performed significantly worse than controls on most of the JEF-C^© subscales and total score, with 41.4% of participants with ABI classified as having severe executive dysfunction. No significant correlations were found between JEF-C^© total score, the BRIEF indices, and the BADS-C. Significant correlations were found between JEF-C^© and demographic characteristics of the sample and intellectual ability, but not with severity/medical variables.

Conclusion: JEF-C^© is a playful complex task that appears to be a sensitive and ecologically valid assessment tool, especially for relatively high-functioning individuals.     

Lipid profile,inflammation, and oxidative status in peri- and postmenopausal women

Objective: To evaluate the effect of perimenopause and postmenopause on lipid profile, inflammation, and oxidative stress in women.

Methods: This cross-sectional study included 117 women (47?±?6 years) classified as perimenopausal (n?=?47), postmenopausal (n?=?40), or non-menopausal (n?=?30). In serum, we analyzed lipid profile, tumor necrosis factor-alpha (TNF-α), interleukin-1α (IL-1α), and C-reactive protein (CRP). Pro-oxidant status was assessed by thiobarbituric acid reactive substances (TBARS) and protein carbonyls. Antioxidant defense was performed by analysis of superoxide dismutase (SOD) and catalase activities.

Results: Compared to non-menopausal women, triacylglycerols (TG) were similar, total cholesterol and LDL-C were higher in perimenopausal and postmenopausal women, while HDL-C concentrations were decreased. TNF-α and IL-1α were higher in postmenopausal women, while CRP concentrations were elevated in both peri-and postmenopausal women (p?p?p?Conclusion: Menopausal transition and postmenopause were associated with dyslipidemia, inflammation, and unbalanced oxidative status exposing women to cardiovascular risk.     

Effect of heating and enzymatic hydrolysis on casein cow milk sensitivity in Moroccan population

The objectives of the present work were first to evaluate the sensitivity to cow raw milk of the population of Fez, and then to study the effect of heating and pepsin hydrolysis on the allergenicity of casein. A cross-sectional study was carried out in Fez Hospitals, in which 1000 patients were recruited to establish a sera bank used to evaluate specific IgE to cow milk and to casein. Then, we evaluated the reaction of human IgE to heated and pepsin-hydrolysed casein. The results showed that 11.5% of the population studied self-reported reactions to foods. From them, 3.6% reported allergy to milk. Evaluation of specific IgE to cow raw milk showed that 11.9% of patients presented higher specific IgE levels. The treatments of casein indicated that both heating and pepsin hydrolysis totally decreased its binding on the human IgE.     

Predictive factors for late complete atrio-ventricular block after surgical treatment for congenital cardiopathy

The late occurrence of complete atrio-ventricular block (CAVB) after cardiac surgery is rare but potentially responsible for cases of late sudden death. We searched for factors allowing prediction of this complication, retrospectively reviewing the case notes of 11 patients in hospital with complete AVB, 2 months to 10 years after correction of a cardiac malformation. All had a normal pre-operative ECG. The diagnosis had been made based on symptoms in 8 patients: syncope or collapse (4 cases) symptoms on effort (3 cases) or fatigue (1 case). In the others the diagnosis had been made on ECG. The block was infra-His in 5 patients who had electrophysiology. ECG analysis showed that all the patients had CAVB immediately post-operatively lasting 3-14 days. After restoration of conduction the ECGs showed the following anomalies compared to the pre-operative ECGs: long PR (1 case), long PR + right bundle branch block (2 cases), long PR + left axis deviation (1 case), RBBB + left deviation or rotation of the QRS axis (3 cases), long PR + RBBB + left axis deviation (4 cases). All of these patients had been fitted with a cardiac stimulator. In conclusion, the children who had CAVB immediately post-operatively lasting more than 48 hours and who then had an ECG showing different QRS compared to the pre-operative QRS and/or long PR had a risk of late complete AVB. These patients should have electrophysiology and a stimulator must be implanted in those who have an infra-His block.     

Early complicated hypertension, hypokalaemia and salt taste abnormality: a possible link?

Sir, We report the case of a 24-year-old woman, referred in September1998 for grade 2 hypertension since 1994, associated with hypokalaemia(range 2.7–3.1 mEq/l) documented since 1987. Her medicalhistory included an osteosarcoma of the left humerus in 1987and an ischaemic stroke of     

Rituximab-induced interstitial lung disease: case report and literature review

Rituximab, a chimeric monoclonal antibody against CD20, very rarely causes lung toxicity. Toxicity may present as interstitial lung disease, alveolar hemorrhage and adult respiratory distress syndrome. Sixteen cases of rituximab-induced interstitial lung disease (R-ILD) have been reported. With this case and a review of all other cases reported in the literature, we will try to identify the features of R-ILD, its treatment and why the early diagnosis of this complication is important.
