Lighten UP! A Community-Based Group Intervention to Promote Eudaimonic Well-Being in Older Adults: A Multi-Site Replication with 6 Month Follow-Up.

Objectives: Eudaimonic well-being (EWB), increasingly recognized as a critical component of health, typically declines in later life, and there are no existing programs to sustain or increase EWB in older adults. Lighten UP! is an 8-week program to promote EWB through facilitated group sessions in community settings and at-home practice. Building on earlier pilot research, the current study assessed the effect of the Lighten UP! Program using a longitudinal, multi-site design. Methods: Men and women (N = 169) aged 60 and over were recruited from three Wisconsin communities. EWB, life satisfaction, depression, and diverse aspects of health were assessed before and after the program and at 6-month follow up. Results: Participants reported significantly increased EWB; these changes were maintained 6 months later. The specific EWB domains of self-acceptance, positive relations, and personal growth showed the most robust gains. Participants also showed significant and sustained declines in depressive symptoms, anxiety, and hostility. Conclusions: Lighten UP! Program confirmed its positive effects for enhancing EWB in older adults living in multiple community settings. Clinical Implications: Programs that sustain or enhance EWB in older adults can be expected to yield improvements in diverse aspects of mental and physical health.

Modulation of immune cell function by the autonomic nervous system.

This review discusses some of the major findings implicating the autonomic nervous system in the regulation of immune function. The sympathetic nervous system, the primary focus of this line of research, directly innervates the major lymphoid organs, and physiological release of sympathetic neurohormones at these sites has been documented. Leukocytes have been shown to express receptors for catecholamines, as well as neuropeptide Y, and studies in vitro and in vivo have indicated that occupation of these receptors by the appropriate ligands produces functional changes in immunological cells. Finally, altered sympathetic regulation may underlie some of the immunological abnormalities observed in chronic stress, clinical depression, and ageing.

Natural and cellular immune responses in Flinders sensitive and resistant line rats.

Major depression is associated with impairments in natural and cellular immune responses. This study characterized baseline natural and cellular immune function in the Flinders Sensitive Line (FSL) genetic animal model of depression and in Flinders Resistant Line (FRL) controls. Splenic natural cytotoxicity per natural killer (NK) cell was significantly lower in the FSL rats, suggesting that NK cells are less activated at rest in the FSL rats than in the FRL controls. Neither lymphocyte proliferative responses nor interleukin-2 production differed between the two strains. Resting baseline concentrations of plasma adrenocorticotropic hormone and corticosterone were similar between the FSL and FRL rats, indicating that hypothalamo-pituitary adrenal axis activation did not mediate immunological differences. FSL rats show abnormalities in natural immunity similar to those found in clinically depressed human beings, indicating that this animal model may be useful in understanding the neural and neuroendocrine mechanisms associated with immune alterations in depression.

Complications of sinusitis in children.

Eight patients (6 to 15 years of age) who had periorbital cellulitis and other complications of sinusitis were studied. Both ethmoid and maxillary sinusitis were present in four patients, frontal sinusitis in two, and ethmoid sinusitis and pansinusitis in one patient each. Subdural empyema occurred in four patients, in one case accompanied by cerebritis and brain abscess and in another by meningitis. Periorbital abscess was present in two children who had ethmoiditis. Alveolar abscess in the upper incisors was present in two children whose infection had spread to the maxillary and ethmoid sinuses. Anaerobic bacteria were isolated from the infected sinuses in all the patients. These were seven isolates of Bacteroides sp, four Fusobacterium sp, three microaerophilic streptococci, three Gram-positive anaerobic cocci, and two Veillonella sp. There was only one aerobic isolate recovered, a group F beta-hemolytic. Streptococcus. Surgical drainage and appropriate antimicrobial therapy resulted in complete eradication of the infection in all patients. The role of anaerobic bacteria in sinus infection and its subsequent complication is discussed. Given the possible serious complications of this disease, the early recognition of sinusitis in children and the institution of appropriate antimicrobial and surgical therapy are of great clinical importance.

Context-dependent behavioral effects of interleukin-1 in the rhesus monkey (Macaca mulatta).

The behavioral effects of recombinant human interleukin-1 alpha (IL-1) in rhesus monkeys (Macaca mulatta) were assessed in 3 experimental paradigms: (1) a testing situation in which an initial quiescent period was followed by a challenge designed to evoke agitation; (2) a novel environment with a social partner; and (3) a working memory-dependent nonspatial cognitive task. In the first two experiments we replicated our previous observations that a high IL-1 dose (25 micrograms) induces somnolence in a quiet setting within 1 h. A lower IL-1 dose (1 ng) did not have these sedative properties, but both IL-1 doses significantly reduced the number of vocalizations made by the monkeys. In contrast, when the monkeys were challenged through direct eye contact with a human experimenter, the 25 micrograms IL-1 dose significantly increased agonistic behavior. Finally, performance on a working memory-dependent task (delayed non-matching-to-sample) was unaffected by doses of IL-1 ranging from 1 to 25 micrograms, possibly because the monkeys were tested after learning the task rather than during the acquisition phase. These results demonstrate that high levels of IL-1 in peripheral circulation can have potent behavioral effects in the nonhuman primate, but that the nature of the influence will depend on the context in which the animal is evaluated. Manifestation of cytokine-induced 'sickness behavior' appears to require a permissive environment.

Diagnosis of joint effusion on lateral and axial projections of the knee.

Lateral and axial scout radiographs of 100 patients undergoing knee arthrography were evaluated for the presence of joint effusion by multiple observers. Specific observations were characterized. Knee joint effusions were diagnosed with comparable overall accuracy on lateral and axial projections. The combination of both projections increased sensitivity from 75% to 91% and decreased specificity from 87% to 27%.

A role for CRH and the sympathetic nervous system in stress-induced immunosuppression.

Central CRH coordination of the behavioral and physiologic sequelae of stress has been well established, and so it is parsimonious to suggest that CRH might also coordinate the immunologic sequelae. The studies presented here lend support to this suggestion. CRH administration into the brain was shown to modulate aspects of both cellular and humoral immune function, and the inhibition of CRH release in the brain following stress inhibited stress-associated immunosuppression. The effects of CRH appear to be mediated by the sympathetic branch of the autonomic nervous system, as chemical sympathectomy and pharmacological blockade of beta-adrenergic receptors both reversed the effects of CRH on immune function. In contrast, removal of the adrenal glands did not alter the immunologic effects of CRH. These links among CRH in the brain, sympathetic activation, and immune function suggest the possibility that immune function may be altered in other conditions characterized by elevated sympathetic tone, such as depression and aging, and that these alterations may be attributed to CRH dysregulation in the brain. These studies shed light on the intricate relationship between the brain and the immune system, and also illuminate its complexity. The differential regulation of CRH in the brain and the periphery is one example of the latter. These findings also set the stage for potential clinical intervention with CRH antagonists, for example, to treat compromised immune function associated with chronic stress, depression, or aging.

Pain, disability, and psychological functioning in chronic low back pain subgroups: myofascial versus herniated disc syndrome.

A series of patients with chronic low back pain evaluated at a tertiary referral center were the subjects for this study. Of 250 consecutive patients, 94 were diagnosed as having myofascial pain and 57 as having herniated disc syndrome. Before evaluation and diagnosis, all patients completed the McGill Pain Questionnaire, ratings of pain and disability, and the Symptom Checklist 90-R. Patients were also grouped on the basis of previous surgical history and workers' compensation benefits. Patients suffering from myofascial pain were significantly less likely to report periods of pain relief than patients with herniated disc syndrome. Those receiving workers' compensation benefits reported significantly greater levels of pain, disability, and psychological distress than those not receiving benefits, irrespective of diagnosis. Patients who underwent previous surgery did not differ significantly from those who never underwent surgery. All patients had elevated scores on the Somatization subscale of the Symptom Checklist 90-R. Patients with myofascial pain and workers' compensation benefits demonstrated the highest levels of somatization and phobia. These findings suggest that the effects of low back pain of myofascial origin have comparable, if not worse, consequences than disc herniation. These findings also reaffirm the importance of workers' compensation in understanding the differences in patients with chronic low back pain.

A retrospective analysis of airway endoscopy in patients less than 1-month old.

OBJECTIVES: To review the authors' experience with neonates who underwent endoscopy over an 8-year period. STUDY DESIGN: Retrospective review in a tertiary care children's hospital. METHODS: Sixty-two neonates who underwent endoscopy were reviewed. RESULTS: Common indications for endoscopy were stridor (56%), apnea/cyanotic episodes (30%), and feeding difficulty (23%). Laryngeal abnormalities were the most frequent finding, including laryngomalacia (19%), glottic edema (19%), and vocal cord paralysis (13%). Pierre Robin sequence was the most common associated anomaly. Forty-eight neonates (77.4%) had more than one endoscopic finding. Gastroesophageal reflux diagnosed by barium swallow or esophageal pH monitoring was found in 34%. Gastroesophageal reflux was the only identified etiologic factor in four cases. Computed tomography and magnetic resonance imaging provided less information than endoscopy. CONCLUSIONS: Endoscopy in symptomatic neonates can determine etiology of distress most of the time. Multiple diagnoses were found in 77.4% of the neonates, emphasizing the need for a thorough aerodigestive tract examination. Concomitant diagnoses including gastroesophageal reflux, congenital heart disease, and pulmonary disease were found in 87.1% of neonates. Neonates have a higher likelihood of having multiple lesions in the aerodigestive tract as compared with older infants or children.

Childhood pseudohypacusis in patients with high risk for actual hearing loss.

OBJECTIVE: While pseudohypacusis or nonorganic hearing loss is a well-recognized phenomenon in adults, it is the aim of this report to heighten the physician's awareness of the occurrence of nonorganic hearing loss in pediatric patients. The medical and otologic histories of 18 cases identified consecutively between 1983 and 1991 at The Children's Hospital, Boston, Massachusetts, were retrospectively reviewed. In these selected cases an analysis of the audiometric configuration, age range, and sex distribution is undertaken. This review highlights the need to rule out pseudohypacusis even in pediatric cases where suspicion is low. A precedent trauma was the presenting complaint in a high percentage of our patient population. This association has not been previously reported in the pediatric literature. While the severity of the traumatic incident was often minor, extensive medical and surgical investigations had been considered before the identification of nonorganic hearing loss. STUDY DESIGN: A retrospective chart analysis of patients identified with pseudohypacusis over a 7-year period. METHODS: A tertiary care children's hospital in an urban community. Eighteen consecutively identified patients examined by a staff audiologists at a tertiary care children's hospital. A specific battery of standard audiologic testing with the goal of detecting pseudohypacusis in children. RESULTS: Successful if additional interventions such as exploratory tympanotomy were avoided. CONCLUSIONS: Pseudohypacusis was identified in 18 patients with a majority having an antecedent history of trauma. Additional interventions were canceled upon the detection of true threshold values. A high index of suspicion of pseudohypacusis in children and an organized standardized battery of audiologic testing will facilitate early identification of these patients and will avert inappropriate interventions.

Bacterial tracheitis--two-year experience.

Inflammatory illnesses of the pediatric airway cause significant morbidity and mortality. Bacterial tracheitis is a distinct entity with features common to both croup and epiglottitis. Ten patients between the ages of 3 months and 12 years were treated at Children's Hospital, Boston, MA., for bacterial tracheitis. The clinical presentation and medical management is discussed. Seven of the patients required both direct laryngoscopy and bronchoscopy; one patient required urgent intubation; and one patient required indirect laryngoscopy. In one patient the diagnosis was based on clinical and radiographic findings in conjunction with tracheal aspirates. Seven of the 10 patients did well with aggressive medical management. Three patients required endotracheal intubation. No patient required tracheotomy, and there were no cardiopulmonary arrests. It is of particular interest that although the patients in this series presented in a manner similar to that of patients in other published series, the management is significantly different and the overall outcome is significantly better.

Vincristine-induced recurrent laryngeal nerve paralysis.

Vincristine-sulfate-related vocal cord paralysis has been reported infrequently in the literature. The neurotoxicity of the vinca alkaloids is well-known; however, the potential for cranial nerve involvement is not widely recognized. Given the complexity of the typical patient receiving such a chemotherapeutic agent, the potential for misdiagnosis is high. Many patients have primary tumors or metastatic lesions in sites that could cause the clinician to overlook this reversible cause of neurologic dysfunction. This study describes the first three reported pediatric cases of vincristine-induced vocal cord paralysis. Two patients developed increasing stridor secondary to bilateral vocal cord paralysis; the third developed a unilateral vocal cord paralysis. All resolved spontaneously upon withdrawal of the vincristine. Vinca-alkaloid-induced vocal cord paralysis is a potentially dangerous but reversible lesion. Otolaryngologists should be aware of the association between these agents and cranial nerve neuropathies.

Central nervous system complications associated with acute otitis media in children.

The purpose of this article is to review a subset of pediatric patients with otitis media occurring simultaneously with meningitis and other central nervous system diseases. Of the 92 cases reviewed, 61.3% involved patients under 12 months of age. Meningitis associated with otitis media involved 91% of the patients; the remainder had nonmeningitic central involvement. The most striking finding was the high incidence of Haemophilus influenza type-B, a relatively uncommon pathogen of the middle ear. This finding highlights the need to select antibiotic coverage to adequately treat Haemophilus influenza type-B.

Congenital cholesteatoma of the middle ear in children: a clinical and histopathological report.

Forty-one children with congenital cholesteatoma of the middle ear seen from 1978 through 1989 are reviewed. The most common presentation was that of an asymptomatic white mass behind a normal intact tympanic membrane. Computed tomography (CT) scan was useful in documenting extension beyond the mesotympanum. Surgical removal was performed using an extended tympanotomy for lesions in the middle ear and tympanomastoidectomy for those that had extended into attic and mastoid air cells. Observation over an average 3.1-year period indicated that 80% of children were free of disease after initial surgery. Residual disease that required further surgery was present in 20%. The importance of early diagnosis of congenital cholesteatoma is strongly advocated. The prognosis is better when the cholesteatoma is confined to the anterosuperior quadrant of the middle ear. Seventeen patients in this study had such a lesion, and extended tympanotomy allowed removal of an encapsulated closed cholesteatoma with normal postoperative hearing and no residual cholesteatoma. The average age was 2.3 years. Temporal bone histopathological studies of three cases of congenital cholesteatoma demonstrate two distinct pathological types of congenital cholesteatoma. A "closed" keratotic cyst in the anterior mesotympanum, which is easily removed, and an "open" infiltrative type in which there is no containment of the keratotic debris and the cholesteatoma matrix is in direct continuity with middle ear mucosa. Surgical extirpation of the "open" type is difficult and more likely to be associated with residual disease.

Computed tomography in the evaluation of choanal atresia in infants and children.

While traditional confirmatory clinical tests are helpful in establishing the diagnosis of choanal atresia, they give little useful information concerning the composition, position, and thickness of the atresia plate. Surgeons experienced in the repair of choanal atresia have recognized that detailed anatomic assessment is valuable in the preoperative selection of the method of repair and design of the repair once undertaken. The utilization of high-resolution computerized tomography to provide such information in a group of infants and children with choanal atresia forms the basis for this report. The application of computed tomography in the evaluation of choanal atresia and preoperative surgical planning is discussed. Based on this experience, we feel that the introduction of high-resolution computerized tomography is a significant advance in the diagnostic and therapeutic approach to choanal atresia and should be the single radiographic procedure of choice.

Chronic pediatric stridor: etiology and outcome.

Stridor in children is usually acute. This paper represents a chart review and telephone survey of 60 patients with chronic pediatric stridor. The most common etiology was laryngomalacia, which required airway intervention in 22% of the patients. The symptoms persisted beyond 18 months of age in 17% of the patients. Twelve percent of the patients had multiple lesions; 65% of the second lesions were below the vocal cords. It appears that the presence of cyanosis should increase physician suspicion of multiple lesions. There was not a higher risk of recurrent upper respiratory infections with any of the diagnoses.

Tenuous airway in children with trisomy 21.

Multiple congenital anomalies are closely linked to Down syndrome (trisomy 21). Cardiac malformations are found in 40% of patients, a large number of whom will require a major surgical procedure. The importance of postextubation stridor in these children is frequently underestimated. A retrospective review of 99 trisomy 21 patients who underwent cardiovascular surgery revealed postextubation stridor in 24 (24.2%). Significant factors for the development of stridor included younger age (P=0.04), lower growth percentile for weight (P=0.03), and increased frequency of reintubation (P=0.04). Subglottic stenosis was found in 6 (6.1%). In 4 of these patients, an endotracheal tube of larger diameter than predicted for age was used. All 6 patients were less than the 10th percentile for weight. We conclude that Down syndrome patients deserve special considerations and modifications of standard intubation techniques for successful airway management.

Acquired nasopharyngeal stenosis: a warning and review.

OBJECTIVES: To present and discuss the clinical presentation and treatment planning in children with acquired nasopharyngeal stenosis (NPS) following tonsillectomy and adenoidectomy. DESIGN: Case series. SETTING: Tertiary care center. PATIENTS AND OTHER PARTICIPANTS: Nine children identified over 2 years (1995-1996) with newly diagnosed NPS were evaluated. Seven of these children underwent adenoidectomy using a potassium titanyl phosphate laser technique at a neighboring facility. These children were aged 15.6 to 62.1 months at the time of original surgery, and all presented with nasal obstruction and mouth breathing beginning within 10 weeks after surgery. In addition, 5 had newly documented obstructive sleep apnea. RESULTS: Of the 9 children, 1 required a tracheotomy. After undergoing an adenoidectomy, chronic rhinosinusitis developed and aggressive medical treatment failed in 4 children. Time from symptom onset to diagnosis of NPS ranged from 2 to 34 months. The diagnosis of NPS depends on obtaining a thorough medical history and conducting a physical examination that includes nasopharyngoscopy. Most children underwent a computed tomographic scan prior to repair. The scarring encountered in these patients involved the soft palate and the posterior pharyngeal wall and/or choanae bilaterally. Five children had no identifiable eustachian tube opening into the nasopharynx, and all 5 children had chronic otitis media with effusion or persistent otorrhea. CONCLUSIONS: Nasopharyngeal stenosis following adenoidectomy and/or tonsillectomy is difficult to correct. Multiple surgeries may be required to relieve the obstruction. Standard operative techniques using the lateral pharyngeal flap and transpalatal or endoscopic intranasal approaches were adapted to the clinical situation. Prolonged use of nasal stents is mandatory to produce a nasopharyngeal opening. Adjunctive treatment may include pressure equalization tubes. However, the best treatment remains prevention.

Surgical management of macroglossia in children.

Congenital macroglossia is associated with a variety of syndromes, most commonly Down syndrome and Beckwith-Widemann syndrome. Clinically, macroglossia may result in respiratory compromise, dysphagia, and poor cosmesis. A variety of treatments have been proposed, with surgical resection being the most common. We review management and describe a new surgical technique, consisting of a keyhole resection to decrease the width and length of the tongue. Between 1990 and 1992, five keyhole resections for congenital macroglossia were performed on four consecutive children at Texas Children's Hospital, Baylor College of Medicine, Houston. Patients had improved cosmesis and improved function of the oropharyngeal airway, with no change in speech and feeding. Keyhole resection is an effective treatment for macroglossia.

Airway complications in CHARGE association.

The association between catastrophic airway events and developmental delay was examined in patients with CHARGE (coloboma, heart disease, atresia choanae, retarded growth and/or development, genital hypoplasia, and ear anomalies and/or deafness) association. A retrospective chart analysis was performed from The Children's Hospital in Boston, Mass. Sixteen patients were identified with CHARGE association. Nine patients had at least one respiratory arrest, and 7 had no airway difficulties. Some degree of developmental delay was seen in 14 patients, but was most severe in those patients who suffered a respiratory arrest. We conclude that children with CHARGE association have a propensity for airway instability and that cerebral hypoxia contributed to the developmental delay in some of our patients. We recommend early tracheotomy rather than early choanal atresia repair in these patients to protect the central nervous system.
