- The objective of the study was to assess both the possible complications of percutaneous endoscopic gastrostomy (PEG) in pediatric cancer patients and its effect on weight development. The medical records of 18 children with a median age of 2.5 years (range, 0.5-14.2 years) were reviewed. The diagnoses were leukemia, central nervous system tumors, solid tumors, and lymphoma. The indications for PEG were anticipated therapy-related nutritional problems and inadequate food intake, weight loss, swallowing problems in relation to paresis of the pharynx, and relapse of the disease. Ten children received a PEG at treatment start, and eight children received it at a median time of 3.4 months (range, 0.9-27.4 months) after treatment start. The median duration of having a PEG in place was 12.3 months (range, 1.2-24.0 months). At admission the median weight for age expressed as standard deviation (SD) was -0.11 (range, -2.78-2.68). There was a significant (p =.005) decrease in the median SD from admission until PEG installation. There was also a significant increase in the median SD from the start of PEG use until 1 (p =.04) and 2 (p =.039) months after start. The most common complications were episodes of inflammation of the PEG site, which were successfully treated with topically or orally administered antibiotics, and episodes of infection, which required intravenously administered antibiotics. Taking into consideration the medical condition of the children in the study group and the considerable length of time with a PEG in place, we believe that nutrition via PEG in children with cancer has several advantages and is rarely associated with other than minor complications.

- Distressing events for children with cancer (N = 121), 0 to 19 years of age, were investigated. Data were gathered through interviews with 50 children, 65 parents, and 118 nurses. Each participant was asked: "Has there been any especially distressing event for you/your child/the child with regard to disease and treatment?" Data were analyzed by content analysis. The categories that emerged from the analysis were grouped into a physical and an emotional dimension. The most frequently mentioned aspects of distress referred to the physical dimension: pain resulting from diagnostic procedures and treatments, nausea, and fatigue. The most frequently mentioned physical aspect of distress was, for children 0 to 3, 4 to 7, and 8 to 12 years of age, pain resulting from diagnostic procedures and treatments, and for children > or =13 years of age, nausea. The most frequently mentioned aspects of distress referred to the emotional dimension were categorized as confinement, feeling of alienation, and worry before medical procedures. The most frequently mentioned emotional aspect of distress was, for children 0 to 3 years of age, confinement; 4 to 7 years of age, feeling of alienation; 8 to 12 years of age, worry about death; and > or =13 years of age, changed appearance. For children 0 to 3, 4 to 7, and > or =13 years of age, aspects of distress of a physical character were mentioned most frequently. For children 8 to 12 years of age, aspects of distress of an emotional character were mentioned most frequently.

Parents' perception of their child's food intake after the start of chemotherapy

- Adequate nutrition is an important part of supportive therapy for the pediatric cancer patient. The aim of this study was to assess parents' perceptions of their child's eating pattern after onset of chemotherapy and the strategies they used to cope when eating problems arose. A semistructured interview was performed with parents of 11 consecutively admitted children. The results showed that parents have a realistic perception of their child's food intake and that they are able to recognize reasons for poor food intake that may be unknown to the staff. The individual responses of the parents and the mechanisms of coping were unique for each individual. The responsibility of getting the child to eat was distressing for many parents. The study indicates that parents need continuous support to serve an optimal role in the nutritional care of their child. Copyright 2001 by Association of Pediatric Oncology Nurses

Optimum operating conditions in drying foodstuffs with superheated steam

- It is inferred from experimental data that in drying foodstuffs with superheated steam, the initial drying rate has a direct effect on the rate at which the overall drying takes place. That is, the faster the initial drying rate, the shorter the overall drying time. This criterion is very convenient because at the beginning, water moistens the sample external surface so evaporation does not depend on internal sample characteristics, but only on external convective heat and mass transfer rates. Mass and energy balance equations are solved and the result converted into a general initial drying rate equation, in which all dryer characteristics are grouped into one dimensionless parameter. The initial drying rate equation is mathematically maximized and the optimum working conditions determined. The result shows that initial drying rate always increase with increases of either the superheated steam temperature or velocity, but once these two variables are fixed, there exists at least one "optimum" pressure at which the initial drying rate is a maximum. Finally, the initial drying rate and optimum condition equations are applied to three model dryers, a dryer for a flat sheet, a fixed bed dryer and a rotary dryer. In each case, numeric values are computed and plotted as drying rate versus pressure curves, in which the optimum drying rate is also included. Also presented is a chart to compare the optimum pressures as functions of temperature and steam velocity for the three dryers.
