A proton therapy model using discrete difference equations with an example of treating hepatocellular carcinoma.

Proton therapy is a type of radiation therapy used to treat cancer. It provides more localized particle exposure than other types of radiotherapy (e.g.

Systemic lupus erythematous revealed by cytomegalovirus infection.

Cytomegalovirus (CMV) infection have been described as exacerbing systemic lupus erythematous (SLE). The role of CMV in starting off SLE remains object of debate. We report a severe presentation of SLE revealed by CMV infection with hemophogocytic syndrome.

Low antibiotic resistance rates and high genetic heterogeneity of Escherichia coli isolates from urinary tract infections of diabetic patients in Tunisia.

Antimicrobial resistance phenotypes, tetracycline, sulphonamide resistance genes, and integrons were analysed in 48 Escherichia coli isolates recovered from urine cultures of diabetic patients in Tunisia. Twenty-one were susceptible to all antibiotics tested. High rates of resistance were observed for amoxicillin (39.

Transient symptomatic zinc deficiency in a breast-fed infant: relevance of a genetic study.

Objective: We present a case of acrodermatitis enteropathica in a full-term, breast-fed, 7-mo-old infant born from consanguineous parents with a family history of acrodermatitis enteropathica.

Methods: The patient presented with periorificial and symmetric acral lesions, which prompted us to review the clinical features of acrodermatitis enteropathica and its pathogenesis. Laboratory investigations showed low zinc levels in the infant's and mother's sera and in the mothers' milk.

Linear IgA bullous dermatosis in tunisian children: 31 cases.

Background: Linear IgA bullous dermatosis (LAD) of children is relatively frequent in Africa.

Aim: We undertook this study to evaluate the frequency of this disease among autoimmune bullous diseases (AIBDs) in Tunisian children.

Materials And Methods: We present a 32-year retrospective study (January 1976 to December 2007).

Agminated Spitz nevi arising on a nevus spilus after chemotherapy.

Agminated Spitz nevus arising on a background of nevus spilus (NS) is a rare condition. We report here a further case in a child that is original because it is induced by chemotherapy. A 3-year-old boy presented 3 months after the onset of a chemotherapy for a vesico-prostatic rhabdomyosarcoma, multiple pigmented papulo-nodules located on the face, neck, chest wall, and the higher back.

[Pemphigoid gestationis: a pregnancy-related pathology underestimated by obstetricians].

Pemphigoid gestationis (herpes gestationis) is an autoimmune bullous dermotosis occuring dining pregnancy or in the post-partum period. The interaction of this rare pathology with pregnancy is underestimated by obstetricians. Authors report one case of pemphigoid gestationis diagnosed in a pregnant woman at term.
