Tactual exploration by normal infants.

The age of onset for tactual exploration of the fingers, body (torso), knee, foot and penis by the fingers was determined in 100 normal infants. Exploration of the mouth, face, head, ears, nose and eyes was also studied by daily observations in the first three days of life in a second sample of 12 normal newborns, and the age of onset was recorded. The data show that the ability of the normal infant to explore by touch the various parts of his body appears to have a definite age of onset and a definite sequence.

The effects of noise on the vestibular system.

PURPOSE: Subjects with noise-induced hearing loss sometimes also complain about balance disorders, but reports of clinical series that give contradictory results are highly controversial. This study was designed to evaluate the effects of intense noise on the vestibular labyrinth, both in subjects with symmetrical hearing loss and in subjects with asymmetrical loss, and to examine the correlation between the subjects' complaints and the results of the vestibular function tests. METHODS: A total of 258 male military personnel, heavily exposed to various intense noises, were included in the study. They were divided into 2 groups according to their hearing; 134 had a symmetrical high-tone hearing loss, and 124 had asymmetrical losses. Each group was divided into 2 subgroups according to the presence or absence of vestibular complaints. All of the subjects underwent a complete audiological and electronystagmographic evaluation. RESULTS: We found that vestibular damage caused by intense noise exposure might be expressed clinically in subjects with asymmetrical hearing loss. There was a strong correlation between the subjects' complaints and the results of the vestibular function tests. There was no correlation between the severity of the hearing loss and the vestibular symptomatology and pathology. CONCLUSIONS: Subjects exposed to intense noise may have evidence of vestibular pathology only when there is an asymmetrical hearing loss. Whenever hearing loss is symmetrical, an equal damage to the vestibular system of both ears is most probably responsible for the absence of abnormal findings on the vestibular function tests. The results of this study have important medicolegal implications for individuals exposed to intense noises.

Epstein-Barr virus and cancers of the head and neck.

Denis Burkitt pioneered the association of viruses and cancer in humans with his observations of lymphomatous tumors in children in equatorial Africa. The Epstein-Barr virus (EBV), a human B lymphotrophic herpes virus, is strongly associated with undifferentiated carcinoma of the nasopharynx and African-type Burkitt's lymphoma. More recently, an association of this virus with other epithelial neoplasms, lymphomas, and immunodeficiency-related malignant and nonmalignant conditions has been reported. Since many of these tumors are rare, much of the information is based on sporadic reports and relatively small series of patients. The purpose of this report is to review the literature and examine the growing association of EBV with various head and neck malignancies.

Synergistic necrotizing cellulitis as a complication of peritonsillar abscess.

Peritonsillar abscess, a complication of tonsillitis, is not uncommon. The usual treatment consists of needle aspiration or surgical drainage and antibiotic treatment. Tonsillectomy may be used in the management of this condition, either at the time of diagnosis or after an interval period. Severe complications of peritonsillar abscess are rare. Synergistic necrotizing cellulitis is a fulminant infection associated with spread along fascial plains, necrosis of connective tissue and muscle, and high mortality. It is usually otondogenic in origin in the cervicofacial area and occurs in debilitated or immune compromised patients. We discuss cervicofacial-necrotizing soft tissue disease and report an unusual case of extensive synergistic necrotizing cellulitis of the neck, chest, and shoulder as a result of a peritonsillar abscess.

The association between iron-deficiency anemia and recurrent acute otitis media.

PURPOSE: This study was designed to examine the association between iron-deficiency anemia and the frequency of recurrent acute otitis media in children, and to evaluate the effect of restoring normal hemoglobin levels on the frequency of acute otitis media attacks. MATERIALS AND METHODS: A total of 680 children with frequent episodes of acute otitis media were enrolled in the study. The levels of the hemoglobin were measured in both these children and in 200 healthy children with no history of infections. The correlation between hemoglobin level and the frequency of middle ear infections was studied and analyzed. All children with hemoglobin levels lower than 9.5 g/dL received iron supplementation until they reached a level of at least 11 g/dL, and the subsequent frequency of middle ear infections was recorded. RESULTS: The 680 children had an average of 8.3 +/- 2.7 episodes of acute otitis media per year per child, and an average hemoglobin level of 11.4 +/- 2.7 g/dL, whereas the controls had an average hemoglobin level of 13.1 +/- 2.5 g/dL. Twenty percent had hemoglobin levels below 9.5 g/dL. These children had more episodes of acute otitis media when compared with children with average levels. By increasing the hemoglobin level in these children, the frequency of the episodes of acute otitis media decreased significantly. CONCLUSIONS: This study confirms that anemic children have higher prevalence of episodes of acute otitis media in comparison to healthy, nonanemic children, and shows that there is a direct relationship between the degree of the anemia and the number of the episodes.

Critiquing as a method of evaluation in the classroom.

The criticism model of evaluation in a humanistic educative paradigm is a shared teacher/student evaluative activity based on a trusting relationship in which students become connoisseur critics. Among the standards for critiquing are criteria for student/teacher interactions and criteria for learning activities. The author provides examples of student/teacher critiquing activities employed in a graduate nursing course and suggests ways for faculty to develop skills in the critique method of evaluation.

Hardiness and anxiety as predictors of academic success in first-year, full-time and part-time RN students.

BACKGROUND: The levels of hardiness and anxiety and their relationship with academic success were examined using the Personal Views Survey and the State-Trait Anxiety Inventory. METHOD: The instruments were administered to a nonprobability convenience sample of 41 full-time and part-time RN students enrolled in a BSN completion program. RESULTS: Participants perceived themselves as possessing moderately high levels of hardiness (mean = 72.90) and low levels of anxiety (state mean = 39.33; trait mean = 40.18), but for some, these characteristics did not relate to academic achievement. Statistical significance was set at .05. CONCLUSION: These findings indicate how hardiness and anxiety can affect academic success, particularly in adult students, and provide some direction for educators and administrators in maximizing educational endeavors.

Computer conferencing in graduate nursing education: perceptions of students and faculty.

The authors report the perceptions of students and faculty who participated in a computer conferenced (CC) graduate course in nursing. Ten graduate students and three faculty members completed a course evaluation form, which included items about learning, interaction, environment, technical support, and satisfaction with CC. Responses indicated the CC medium offered a creative and flexible alternative for learning. Course participants perceived benefits such as enriched learning, meaningful interactions, opportunities for reflection, satisfaction with the technology, and the convenience of learning from a distance. These results have implications for facilitating continuing education.

Reciprocal learning among students in the clinical area.

Reciprocal learning is a cooperative, collegial method in which there is mutuality of student to student or student to faculty interaction, assistance, and benefits. This teaching method is congruent with curriculum revolution concepts. The authors describe reciprocal learning and provide an example of its application in the clinical area. Guidelines for implementation of the strategy are presented.
