Joint effect of temperature and insect chitosan on the heat resistance of Bacillus cereus spores in rice derivatives.

The heat resistance of Bacillus cereus spores inoculated in a rice substrate supplemented with insect chitosan as an alternative antimicrobial was studied. Two concentrations of insect chitosan were considered in order to assess the role of the insect chitosan concentration during the heat process. Results of the study indicated that the DT values were higher in the substrate without chitosan than in the substrate containing chitosan thus indicating a greater heat resistance to heat treatment of the microorganism inoculated in the substrate without chitosan.

Panniculitis in the newborn: a case report.

The authors present a case of panniculitis in a newborn, a rare disease in the neonatal period discussing its causes and differential diagnosis, emphasizing a possible diagnosis of erythema nodosum.

Severe osteogenesis imperfecta: case report.

The authors present a case of Osteogenesis Imperfecta, emphasizing the clinical and epidemiological characteristics, forms of classification and treatment of the disease. This is an important case not only to the knowledge of pediatricians and orthopedists, but also for other professionals involved with the problem. This article has been jointly described by the Departments of Pediatrics and Neonatology of the Girassol Clinic in Luanda Capital of the Republic of Angola, Africa.
