phenylephrine-hydrochloride and Weight-Gain

This study compares patients undergoing early cleft lip repair (ECLR) (<3-months) and traditional lip repair (TLR) (3-6 months) with/without nasoalveolar molding (NAM) to evaluate the effects of surgical timing on weight gain in hopes of guiding future treatment paradigms.. Retrospective review.. Children's Hospital of Los Angeles, California.. A retrospective chart review evaluated patients who underwent ECLR or TLR ± NAM from November 2009 through January 2020.. No intervention was performed.. Patient demographics, birth and medical history, perioperative variables, and complications were collected. Infant weights and age-based percentiles were recorded at birth, surgery, 8-weeks, 6-months, 12-months, and 24-months postoperatively. The main outcomes were weight change and weight percentile amongst ECLR and TLR ± NAM groups.. 107 patients met inclusion criteria: ECLR,. ECLR significantly increased patient weights 24-months postoperatively when compared to TLR ± NAM. Specifically compared to TLR-NAM, ECLR weights were significantly greater at all time points past 6-months postoperatively. The results of this study demonstrate that ECLR can mitigate feeding difficulties and malnutrition traditionally seen in patients with cleft lip.

To assess weight gain of infants with cleft lip and/or palate (CL ± P) treated with nasoalveolar molding (NAM).. Retrospective, case-control chart review.. Doernbecher Children's Hospital, Oregon Health & Science University, Portland, Oregon.. Infants with nonsyndromic CL ± P and noncleft controls.. Prior to primary lip surgery, NAM was either included (+NAM) or not included (-NAM) in the cleft treatment protocol.. Weight gain and percentage weight gain relative to initial weight were compared among +NAM, -NAM, and control groups from birth to 7 months and from birth to 36 months.. Comparing +NAM and -NAM groups, no significant difference in weight or percentage weight gain was found in either time window. Compared to controls, from birth to 7 months, both CL ± P groups weighed less (. Comparisons of CL ± P infants treated with and without NAM showed that with the NAM appliance, despite its added complexity, there was no adverse impact on weight gain. Comparisons to noncleft, control infants suggests that NAM treatment may have a beneficial impact on weight gain.

The health risk of inhalation exposure to polychlorinated biphenyls (PCB) cannot be assessed with high confidence due to the lack of rigorous inhalation studies. One uncertainty rests on exposure regimen, as whole-body exposure systems allow oral PCB intake that confounds the exposure. We conducted contemporaneous PCB inhalation exposures with whole-body and nose-only exposure methods. Female Sprague-Dawley rats were concurrently exposed to vapor-phase PCBs (533 ± 93 μg/m(3)) generated from PCB11-supplemented Chicago Air Mixture resembling the Chicago airshed, 4 h/day, 6 days/week, for 4 weeks. Congener-specific analysis showed 1.5-fold higher ∑PCBs in the lungs of nose-only exposed than the whole-body exposed animals (p = 0.0024). Higher ∑PCB concentrations were also found in the sera, livers, brains, and adipose tissue of nose-only exposed animals (1.1-1.5-fold), but these increases were not statistically significant. Congener profiles of five tissue types were dominated by PCB 28/31 and higher-chlorinated congeners in both groups reflecting rapid metabolism of other lower-chlorinated PCBs. No toxicity was seen regarding metabolic enzyme expression, glutathione, or histopathology. However, diminished weight gain and reduced plasma total thyroxine levels were found in both groups compared with controls, after exposure to 76 μg/m(3) ∑PCBs as adjusted for continuous exposure. Hepatic lipid peroxidation was also elevated in the nose-only group. Our study shows that prolonged nose-only exposure was well-tolerated and eliminated the need for housing animals outside the vivarium, thus was preferred for long-term PCB inhalation studies.

To explore the value of employing the small intestinal feeding tube in treating high position intestinal obstruction of newborn infant.. Five newborn infants (3 males and 2 females; 1 premature infant and 4 fully-mature infants; 2 had membranous atresia of duodenum, 1 had annular pancreas, and 2 had proximal small intestine atresia; 1 infant had malrotation). The duodenal membrane-like atresia and the blind-end of small intestine were removed and intestinal anastomosis was performed, which was combined with intestinal malrotation removal. Before the intestinal anastomosis surgery, the anesthetist inserted via nose a 6Fr small intestinal ED tube, made by CREATE MEDIC CO LTD of Japan[. the State Food and Drug Administration-instrument (Im.) 2007-NO.2661620]. Twenty-four hours after surgery, abdominal X-ray plain film was taken and patients were fed with syrup; 48 hours later, formula milk was pumped or lactose-free milk amino acids were given by intravenous injection pump through the feeding tube. The amount of milk and fluids was gradually increased to normal amount according to the condition. In initial 3 days the intravenous nutrition was given and one week after operation, the infants were fed through mouth in addition to pumping milk through the tube and stopped infusion. Ten to 22 days after operation, the tube was removed and the infant patients were discharged.. All the five infants showed that the feeding through the nutrition tube was accomplished and the time of venous nutrition was reduced and fistula operation was avoided. None of the infants on question was off the tube and no jaundice exacerbation was found and the liver function was also found normal. At the very beginning, the tube was occasionally blocked by milk vale in one infant and after 0.9% sodium chloride solution flushing patency restored. After that, the feeding tube was washed once with warm water after feeding. In one infant vomiting occurred due to enough oral milk. The photograph of upper gastrointestine did not show anastomomotic stricture or fistula, or intestinal obstruction. After pulling out the tube, the symptoms disappeared and then the patient was discharged. One child was found to have diarrhea with no lactose nutrition liquid and given compound lactic bacteria preparations for oral administration, the symptom disappeared. In the 5 cases, the shortest hospital stay was 10 days and the longest was 22 days, the average stay was 16 days. Three to 5 days after operation the weight restored to birth weight, the weight had increased, when discharged, to an average of 5.5 g (kg·d).. The small intestinal feeding tube was very effective for the postoperative nutrition maintenance of high position intestinal obstruction in newborn infants.

Belly nosing is an abnormal oral-nasal behavior that can develop to high levels in newly weaned piglets and may signal nutritional need. The effects of feed restriction on both behavior and metabolic serum parameters were examined in 128 weaned piglets. All pigs were fed ad libitum during week 1, and during week 2, half of all pens (N=8) were restricted to 65% of ad libitum intake. Blood samples were collected on days 3 and 10 after weaning and behavior was observed from video recordings on days 5 and 12. Piglets were classified as early 'nosers' or early 'non-nosers' based on their behavior on day 5. Feed restriction resulted in elevated non-esterified fatty acids (NEFA), beta-hydroxybutyrate (BHB) and both lower glucose and a NEFA/glucose ratio, but belly nosing was not affected. Piglets classified as 'nosers' did not have blood profiles indicating they were in greater nutritional need compared to 'non-nosers' in the first week of weaning, nor did they increase belly nosing or other piglet directed behaviors when restricted in week 2. Overall, no associations were found between blood parameters indicative of nutritional stress and belly nosing. This study identifies serum glucose, BHB and NEFA as well as the glucose/NEFA ratio as useful indicators of nutritional stress in newly weaned piglets.

Infection with Erysipelothrix rhusiopathiae has a significant economic impact on pig production systems worldwide. Both inactivated and attenuated vaccines are available to prevent development of clinical signs of swine erysipelas. The ability of a live attenuated E. rhusiopathiae strain to become persistently established in pigs after intranasal exposure and its potential to cause clinical signs consistent with swine erysipelas after being administered directly into the nasopharynx of healthy pigs was evaluated. Five, E. rhusiopathiae-negative pigs were vaccinated by deep intranasal inoculation then followed for 14 days. Nasal swabs were collected daily for 5 days and clinical observations were made daily for 14 days post-vaccination. Nasal swabs were cultured for E. rhusiopathiae with the intent of back-passaging any recovered organisms into subsequent replicates. No organism was recovered from nasal swabs in the first vaccination replicate. A second replicate including 10 pigs was initiated and followed in an identical manner to that described above. Again, no E. rhusiopathiae was recovered from any pigs. No pigs in either replicate showed any signs of clinical swine erysipelas. The live attenuated E. rhusiopathiae strain evaluated in this study did not appear to become persistently established in pigs post-vaccination, did not cause any local or systemic signs consistent with swine erysipelas, and was therefore unlikely to revert to a virulent state when used in a field setting.

During the first few days after weaning, pigs often experience BW loss as they adapt to eating solid food. During this time period, they are also known to drink excessively and develop abnormal oral behavior such as belly nosing. The excessive drinking may stem from the piglets' attempt to satiate hunger through gut fill from a familiar ingestive source. Gut fill through water intake may affect the establishment of feeding behavior. Using drinker devices other than the standard nipple drinker may ease the piglets' transition at weaning by facilitating the initiation of feeding and preventing the development of behavioral problems such as excessive drinking and belly nosing. In this experiment, we examined the effect of drinker type on water and food intake, growth rates, and belly nosing in newly weaned piglets. Eighteen pens of 15 piglets each (270 piglets total) were weaned at 18.1 +/- 0.1 d of age and housed in pens containing 1 of 3 drinker devices (standard nipple, push-lever bowl, and float bowl). Piglets' water and feed intake, water use, BW, and behavior were examined on a pen basis through 2 wk after weaning. Piglets with nipple drinkers wasted more water than the other piglets (P < 0.001; float, 295 +/- 70 mL x pig(-1) . d(-1); nipple, 1,114 +/- 63 mL x pig(-1) . d(-1); and push-lever, 186 +/- 63 mL x pig(-1) . d(-1)), whereas piglets with float bowls consumed less water than the other piglets (P < 0.001; float, 475 +/- 81 mL . pig(-1) x d(-1); nipple, 870 +/- 76 mL x pig(-1) . d(-1); push-lever, 774 +/- 76 mL x pig(-1) . d(-1)). Drinker type affected feeding behavior (P = 0.02); piglets with push-lever bowls spent less time at the feeder than the other piglets, although no difference was detected for feed intake (P = 0.64) or overall ADG (P = 0.16). Piglets with push-lever bowls also tended to perform less piglet-directed nosing behavior than piglets with the float bowl (P = 0.04). Piglets appear to use more water during the first 2 d after weaning with certain drinker devices. However, piglets do not appear to attain satiety through water consumption because most of the water used during the first few days after weaning is wasted. This excessive drinking and water wastage can be abated through the use of push-lever drinkers without negative implications for feed intake or growth rates.

The aim of this study was to assess long-term changes in position of soft tissue landmarks following mandibular advancement and setback surgery.. Twenty-seven patients (14 women, 13 men; mean age, 36 years) who had undergone either mandibular advancement (15 patients) or setback surgery (12 patients), were available for a long-term follow-up an average of 12 years postoperatively. In all of these cases, lateral cephalometric radiographs taken immediately before operation, at 1 week, 14 months, and 12 years postoperatively, were studied.. During the 14 months postoperatively, soft tissue chin and mentolabial fold followed its underlying hard tissue in all patients. A continuous skeletal relapse was observable 12 years after mandibular advancement, but soft tissue chin moved more in an anterior direction. After mandibular setback, soft and hard tissue landmarks remained almost unchanged. Over the entire observation period, a thickening of soft tissue at pogonion was generally seen, and particularly a thickening of the whole chin in the setback group. All patients showed a significant lengthening and thinning of the upper lip. In all except 2 males, the patient's body weight increased markedly.. In contrast to the immediate postoperative stage, soft tissue changes observed an average of 12 years after the primary operation do not directly follow the movements of the underlying skeletal structure. The soft tissue profile changes observed over such a long term seem to be influenced not only by the underlying skeletal structure but also by other factors such as weight gain and aging process.

A series of experiments investigated early pleiotropic effects of a gene for imperfect albinism (s(al-c) in a population of chickens at Jouy-en-Josas, France. An elevated incidence of lesions of the navel, hocks, and nares typical of imperfect albinos were seen on these chicks, confirming their existence in this population. Variations in hatching environment and the amount of light in the hatcher both implicated in contributing to the occurrence of lesions of the hocks and nares, but not to those of the naval. In two experiments, using batteries and cages, early growth was reduced among albinos and early mortality was increased. Significant genotype by environment interactions for weight at 4 days and growth to this time, but not thereafter, suggested that the effect is restricted to this time. Unfavorable environments were most deleterious to albinos. In a third experiment, conducted in floor pens, the gene had no effect on either early growth or mortality. There was no effect of the gene on the lesions, early growth, or mortality when carried by heterozygous males (s+/s(al-c)).

A commercial swine herd was selected for study, because pigs at slaughter repeatedly had lung lesions consistent with enzootic pneumonia and had snout lesions typical of atrophic rhinitis. Pigs born during various seasons of the year were allotted to 4 investigations and were evaluated from birth to slaughter. Individual lungs and snouts were identified and collected at the slaughter plant and later examined for gross lesions of bronchopneumonia and atrophic rhinitis, respectively. Each lesion was scored, and the following comparisons were made within investigations: prevalence and mean scores for lung lesions; prevalence and mean grades for snout lesions; correlations between lung lesion scores and growth indicators; correlations between snout lesion grades and growth indicators; and correlations between lung lesion scores and snout grade scores. Included in the growth indicators were average daily gain during the growing phase, average daily gain during the finishing phase, average daily gain during growing and finishing phases, and days to attain 104.5 kg of body weight. Prevalence of lung or snout lesions, mean values for lung lesion scores, mean values for snout lesion grades, and mean values for the various growth indicators were tested for statistical differences among the 4 investigations. Prevalence of lung lesions was highest (96%) for winter-slaughtered and lowest (81%) for autumn-slaughtered pigs. Mean scores for lung lesions were 7% (summer), 5% (autumn), 9% (winter), and 16% (spring). Prevalence of snout lesions was highest (85%) for spring-slaughtered pigs and lowest (42%) for autumn-slaughtered pigs.(ABSTRACT TRUNCATED AT 250 WORDS)
