Belly models as teaching tools: what is their utility?

Marble/ball models are often used to represent newborn stomach capacity; however, their accuracy has not been determined. The objective of this review was to analyze data on newborn stomach capacity and determine whether marble/ball models serve as accurate representations. A literature search yielded limited data, most emanating from the early 1900s. Data suggest that anatomic capacity of the newborn stomach varies with the birth weight of the infant. Physiologic capacity bears no relation to anatomic capacity of the newborn stomach but is a measure of the ability of the mother to produce milk and the newborn to ingest milk. Given the wide range of feeding volumes on days 1 and 3 and the reported 8-fold increase in average feeding volume during the same time period, it is best to acknowledge that feeding volumes like anatomic stomach capacity vary widely and do not lend well to visual representation by marble/ball models.

Designing a university-based lactation course.

A university-based lactation course was developed to provide lactation education to health care providers, with the goal of improving their knowledge, attitude, and skills in assisting American women to breastfeed. This is a key strategy for achieving the Healthy People 2010 objectives, and it addresses the identified need for education among health care professionals. The university as well as an enthusiastic lactation community provided multidisciplinary clinical experiences and classroom lectures to prepare public health students, nurses, midwives, and nurse practitioners to encourage and assist women in breastfeeding. It is hoped that the success of this class and the experiences of the instructors will motivate other lactation consultants to develop similar educational strategies.

Multipass vector (mpave) technique with nonablative radiofrequency to treat facial and neck laxity.

BACKGROUND: Redundant facial and neck skin is a major feature of aging and historically has been corrected surgically. Recently, monopolar radiofrequency application has been introduced for nonablative tissue tightening of skin by volumetric heating of the deep dermis. It has been able to improve neck and cheek laxity and periorbital rhytides and to elevate eyebrows. However, questions remain as to the ideal parameters needed to optimize the use of radiofrequency. OBJECTIVE: To determine the safety and report on the efficacy of a radiofrequency application that involves a multipass vector (mpave) technique to target facial and neck skin laxity. METHODS: Twenty-five patients (skin types I to V) with mild to severe facial and neck laxity received one treatment session with monopolar radiofrequency. Treatment parameters, adverse events, and digital photographs were recorded. All patients were treated with a multipass vector technique consisting of four to five passes targeted over areas of skin that would most improve facial laxity. The multipass vector (mpave) treatment approach is described. Energy levels ranged from 62 to 91 J/cm2 per pulse. RESULTS: All patients experienced some immediate erythema and edema, which had completely resolved in most patients within 48 hours. No scarring or dyspigmentation was noted on follow-up at 6 and 12 weeks. Photographic analysis of pre- and post-treatment digital images revealed cosmetic improvement in facial and neck laxity in 96% of patients. The majority of patients demonstrated a moderate or better improvement. Stacked pulses in the submental region were shown to reduce fat. CONCLUSIONS: The direct application of monopolar radiofrequency to facial and neck skin using a multipass vector (mpave) treatment approach was safely tolerated in patients of all skin types. Patient satisfaction correlated well with photographic analysis, and the technique was shown to be efficacious for most patients.
