Patients with developmental disorders, including adolescents, comprise a large and heterogeneous group of individuals who vary in underlying diagnosis and degree of disability. The largest numbers of patients are those with cerebral palsy and with traumatic brain injury. While these conditions themselves do not directly cause airway or parenchymal lung dysfunction, consequences of neuromuscular dysfunction, especially aspiration and ineffective cough, may lead to lung damage. Poor nutritional status, impairment of airway clearance by muscular weakness or incoordination and poor pulmonary reserve (due to chest wall or spine deformity) increase the risk of significant morbidity and mortality from respiratory infections. Individuals who were premature infants or who had prolonged neonatal courses may also have residual chronic lung disease (bronchopulmonary dysplasia) contributing to their pulmonary problems. This review discusses conditions that have adverse effects on the airway and lung (drooling, feeding problems, gastroesophageal reflux, aspiration, spasticity, scoliosis) and some of the consequences of these insults (disordered airway clearance, pneumonia, sleep apnea). Also discussed are issues important to the prevention or amelioration of respiratory difficulties, including preventive care, the effects of exercise, dental hygiene, and surgical intervention.

Tiffany, a 3-year-old girl, was referred to the developmental and behavioral pediatrics service for evaluation of significant and persistent negative behaviors associated with refusal to eat at meal time and constant snacking during the past 3 months. She lost 2 pounds, but her weight for her height was at the 50th percentile. Her mother indicated that Tiffany had frequent night awakenings (>10) and late sleep onset (between 12:00 and 1:00 a.m.). Her mother described her as being "easily frustrated," getting upset and angry very quickly. Tiffany was identified at an early intervention program as having mild to moderate developmental delays in pragmatic speech, gross and fine motor skills, and social interaction skills. Tiffany was born at 33 weeks gestation and was hospitalized for 10 days without significant perinatal problems. She was readmitted at 2 months of age when she was diagnosed with gastroesophageal reflux, lactose intolerance, sleep apnea, and bradycardia. She was discharged with an apnea monitor. A seizure disorder was diagnosed at 1 year of age and reactive airway disease at 2 years of age. At the time of the referral to the developmental and behavioral pediatrics service, Tiffany was followed by multiple services, including cardiology, neurology, gastroenterology, psychology, and pulmonary. Pharmacologic therapies included albuterol and cromalyn inhalers, phenobarbital, valproic acid, levocarnitine, ranitidine, and an inhaled steroid. She continued to use the apnea monitor each night, although three sleep studies demonstrated a normal sleep pattern with no evidence of apnea or bradycardia. A recent electroencephalogram was normal. Tiffany lives with her mother and maternal grandparents. Her mother is morbidly obese with a history of asthma and depression. She was infertile for a 10-year period, which she attributed to the stress associated with living with an abusive man. Tiffany was the result of a subsequent, brief relationship with another man; she has not had contact with her father. Her mother is a licensed practical nurse who has not worked as a nurse since Tiffany's birth. An interdisciplinary treatment approach to Tiffany's multiple biological and behavioral problems was implemented by admitting her to a collaborative care unit at a children's hospital.

Cardiorespiratory decompensation or even death may result from dysfunction of upper airway reflexes during sleep. This could manifest, for example, as a lack of pharyngeal dilation in obstructive sleep apnoea or failure of autoresuscitation by gasping in sudden infant death syndrome. Data obtained from experiments in anaesthetized cats suggest several clinicophysiological applications for upper airway reflexes possessing important pathogenetic and therapeutic potentials. Such reflex effects include: 1. Pharyngeal dilation as additional treatment in obstructive sleep apnoea. 2. Bronchodilation after deep nasal breathing in asthmatic attacks. 3. Oesophageal sphincter relaxation alleviating gastro-oesophageal reflux. 4. Provocation of sniff- and gasp-like aspiration for reversal of central apnoea. 5. Arousal from sleep increasing the general reactivity. 6. Increase in muscle tone underlying behavioural defence reactions. 7. Increase in sympathetic activity contributing to powerful cardiopulmonary-cerebral resuscitation. 8. Adrenergic reaction mediated by catecholamine secretion.

Chronic laryngitis is a common disease with a multifactoral genesis. One of the known causal factors is gastrolaryngeal acid reflux as a consequence of gastroesophageal reflux disease (GERD). 10 to 30% of the patients do not show an adequate response to the standard treatment with proton pump inhibitors, which could not be well explained in the past. Our own observations indicate, that sleep related gastroesophageal reflux may play an important role. The special physiological conditions in sleep can impair the reflux, and an increased nocturnal breathing effort in snoring or sleep apnea induces an intensive gastrolaryngeal reflux. This paper explains the pathophysiological background and the diagnostics and differential treatment.

1. In infants, promethazine has been implicated in the pathogenesis of sleep apnoea, apparent life threatening events (ALTE) and the Sudden Infant Death syndrome (SIDS). The aim of the present study was to investigate, in a neonatal animal, the effects of a commonly used promethazine-containing medication on airway protective mechanisms and cardiorespiratory reflexes following simulated gastro-oesophageal reflux (GER) to different levels in the oesophagus and pharynx. 2. Physiological and radiographic recordings were made in 21 naturally sleeping (controls) and 21 sedated (1.5 mg/kg, p.o., promethazine) piglets. On 3 consecutive days physiological recordings were made in all piglets during active sleep. Gastro-oesophageal reflux was simulated by the injection of boluses of 0.5 mL HCl, pH 2 or 3, or NaCl (0.9%) at 37 degrees C into the pharynx, upper or lower oesophagus. 3. In healthy neonatal piglets, minimal sedation with promethazine, which did not affect behaviour during wakefulness, revealed previously unreported findings during active sleep. 4. The most significant effects were observed following simulated GER to the pharynx, with no effect observed in the lower oesophagus. In sedated piglets, compared with naturally sleeping piglets, there was a significant reduction in swallowing (P < 0.01), delayed radiological clearance of fluid (P < 0.05), a reduction in breathing rate, oxygen saturation and heart rate and an increase in apnoea. 5. These findings are consistent with a low dose of promethazine producing a significant attenuation of airway protective mechanisms and, thus, stimulation of the laryngeal chemoreflex. The results suggest a mechanism for the association observed between promethazine use and the occurrence of ALTE and SIDS. The results support continued caution and suggest the need for greater regulation of promethazine-containing medications in infants.

Severe obesity is associated with multiple comorbidities and is refractory to dietary management with or without behavioral or drug therapies. There are a number of surgical procedures for the treatment of morbid obesity, including purely gastric restrictive, a combination of malabsorption and gastric restriction or primary malabsorption. The purely gastric restrictive procedures, including vertical banded gastroplasty and laparoscopic adjustable silicone gastric banding, do not provide adequate weight loss. African-American patients do especially poorly after the banding procedure with the loss of only 11% of excess weight in one study. Gastric bypass (GBP) is associated with the loss of 66% of excess weight at 1 to 2 years after surgery, 60% at 5 years and 50% at 10 years. For unknown reasons, African-American patients lose significantly less weight than Caucasians after GBP. There is a risk of micronutrient deficiencies after GBP, including iron deficiency anemia in menstruating women, vitamin B12, and calcium deficiencies. Prophylactic supplementation of these nutrients is necessary. Recurrent vomiting after bariatric surgery may be associated with a severe polyneuropathy and must be aggressively treated with endoscopic dilatation before this complication is allowed to develop. The malabsorptive procedures include the partial biliopancreatic bypass (BPD) and BPD with duodenal switch (BPD/DS). The BPD appears to cause severe protein-calorie malnutrition in American patients; the BPD/DS may be associated with less malnutrition. Weight loss failure after GBP does not respond to tightening a dilated gastrojejunal stoma or reducing the size of the gastric pouch. These patients may require conversion to a malabsorptive distal GBP, similar to the BPD. However, because of the risk of severe protein-calorie malnutrition and calcium deficiency BPD should be reserved for patients with severe obesity comorbidity. The risk of death following bariatric surgery is between 1% and 2% in most series but is significantly higher in patients with respiratory insufficiency of obesity. In most patients, surgically induced weight loss will correct hypertension, type II diabetes mellitus, sleep apnea, obesity hypoventilation syndrome, gastroesophageal reflux, venous stasis disease, urinary incontinence, female sexual hormone dysfunction, pseudotumor cerebri, degenerative joint disease pains, as well as improved self-image and employability.

Possibly the most important outcomes of bariatric surgery involve changes in obesity-related illness, quality of life (QOL), and psychologic well-being. Dramatic improvement or resolution of serious medical comorbidity accompanies the weight loss following laparoscopic adjustable gastric banding with the LAP-BAND (INAMED Health, Santa Barbara, CA). There are major improvements in the conditions of the metabolic syndrome, which is characterized by impaired glucose tolerance, dyslipidemia, and hypertension. Improvement in insulin sensitivity and pancreatic beta-cell function associated with weight loss induces remission in the majority of type 2 diabetics and reduces the risk of others developing type 2 diabetes. Improvement in dyslipidemia is characterized by raised high-density lipoprotein cholesterol and lower triglyceride concentrations. Together with lower blood pressure, these changes provide a substantial reduction in cardiovascular risk. Other medical conditions caused or aggravated by obesity are also significantly improved, including sleep apnea, daytime sleepiness, asthma, and gastroesophageal reflux. Weight loss is associated with improved fertility and more favorable pregnancy outcomes. All aspects of QOL improve substantially, especially physical disability, and post-weight-loss QOL measures approximate those of the general population. There are also major improvements in body image and reduction in depressive illness. These changes provide perhaps the most compelling data regarding the value of LAP-BAND surgery and underlie the great satisfaction experienced by patients.

A 1991 National Institutes of Health Consensus Conference concluded that severely obese adults could be eligible for bariatric surgery if they had a body mass index (BMI) > or =35 kg/m(2) with or > or =40 kg/m(2) without obesity comorbidity. It was thought at that time that there were inadequate data to support bariatric surgery in severely obese adolescents. An estimated 25% of children in the United States are obese, a number that has doubled over a 30-year period. Very little information has been published on the subject of obesity surgery in adolescents. Therefore we reviewed our 20-year database on bariatric surgery in adolescents. Severely obese adolescents, ranging from 12 to less than 18 years of age, were considered eligible for bariatric surgery according to the National Institutes of Health adult criteria. Gastroplasty was the procedure of choice in the initial 3 years of the study followed by gastric bypass, which was found to be significantly more effective for weight loss in adults. Distal gastric bypass (D-GBP) was used in extremely obese patients (BMI > or =60 kg/m(2)) before 1992 and long-limb gastric bypass (LL-GBP) was used for superobese patients (BMI > or =50 kg/m(2)) after 1992. Laparoscopic gastric bypass was used after 2000. Thirty-three adolescents (27 white, 6 black; 19 females, 14 males) underwent the following bariatric operations between 1981 and June 2001: horizontal gastroplasty in one, vertical banded gastroplasty in two, standard gastric bypass in 17 (2 laparoscopic), LL-GBP in 10, and D-GBP in three. Mean BMI was 52 +/- 11 kg/m(2) (range 38 to 91 kg/m(2)), and mean age was 16 +/- 1 years (range 12.4 to 17.9 years). Preoperative comorbid conditions included the following: type II diabetes mellitus in two patients, hypertension in 11, pseudotumor cerebri in three, gastroesophageal reflux in five, sleep apnea in six, urinary incontinence in two, polycystic ovary syndrome in one, asthma in one, and degenerative joint disease in 11. There were no operative deaths or anastomotic leaks. Early complications included pulmonary embolism in one patient, major wound infection in one, minor wound infections in four, stomal stenoses (endoscopically dilated) in three, and marginal ulcers (medically treated) in four. Late complications included small bowel obstruction in one and incisional hernias in six patients. There were two late sudden deaths (2 years and 6 years postoperatively), but these were unlikely to have been caused by the bariatric surgical procedure. Revision procedures included one D-GBP to gastric bypass for malnutrition and one gastric bypass to LL-GBP for inadequate weight loss. Regain of most or all of the lost weight was seen in five patients at 5 to 10 years after surgery; however, significant weight loss was maintained in the remaining patients for up to 14 years after surgery. Comorbid conditions resolved at 1 year with the exception of hypertension in two patients, gastroesophageal reflux in two, and degenerative joint disease in seven. Self-image was greatly enhanced; eight patients have married and have children, five patients have completed college, and one patient is currently in college. Severe obesity is increasing rapidly in adolescents and is associated with significant comorbidity and social stigmatization. Bariatric surgery in adolescents is safe and is associated with significant weight loss, correction of obesity comorbidity, and improved self-image and socialization. These data strongly support obesity surgery for those unfortunate individuals who may have difficulty obtaining insurance coverage based on the 1991 National Institutes of Health Consensus Conference statement.

We investigated the seroprevalence of Helicobacter pylori in patients with obstructive sleep apnoea. A prospective clinical study consisting of 19 patients, aged 23-72 years with confirmed obstructive sleep apnoea by overnight polysomnography, and 36 control subjects, aged 25-61 years with no history of obstructive sleep apnoea and gastroesophageal reflux complaints, was conducted. Titres of serum H. pylori IgG antibody were assayed by a serum enzyme-linked immunoabsorbant assay. The difference between the study and control groups was analysed by chi-squared test. Seventeen of the 19 patients (89.5%) were found to be H. pylori positive. However, 21 of the 36 control subjects (58.3%) were H. pylori positive. The seropositivity of H. pylori in obstructive sleep apnoea patients was found to be significantly higher than the control group (P = 0.017). The result of our study shows that there is a high association between H. pylori infection and obstructive sleep apnoea. This data may be important for future treatment strategies of the disease.

Some physicians have considered age > or = 50 years as a relative contraindication for bariatric surgery. Recent reports demonstrated the safety and efficacy of Roux-en-Y gastric bypass (RYGB) in this patient subgroup, but comparisons between laparoscopic technique (LT) and open technique (OT) have not been reported. A review of 52 patients > or = 50 years old who underwent RYGB between January 1999 and April 2002 was conducted. Demographics, operative data, and outcomes were assessed. Preoperative and postoperative renal and hepatic functions, electrolytes, anemia studies, and hematology results were compared. Patients were divided into LT and OT groups and operative outcomes were compared. The percentage of excess body weight loss was 66 +/- 4 per cent at mean follow-up of 12 months. Blood samples drawn after a mean of 8 +/- 2 months revealed no postoperative metabolic alterations. RYGB resulted in a reduction of the number of patients with hyperglycemia, hypertension, degenerative joint disease, gastroesophageal reflux disease, and continuous positive airway pressure-dependent sleep apnea (P < 0.05). The LT resulted in fewer intensive care unit admissions and shorter length of stay. RYGB is safe and well tolerated in patients > or = 50 years resulting in no renal, hepatic, or electrolytic alterations. Weight loss and control of obesity-related comorbidities are satisfactory. The LT results in fewer intensive care unit admissions and shorter length of stay than the OT.
