Does Pacifier Use in Infancy Decrease the Risk of Obesity?

BACKGROUND: Nonnutritive sucking using a finger or pacifier is a natural reflex for infants. We hypothesized that infants may overfeed if the bottle or breast is constantly offered. Our goal was to determine whether pacifier use in early infancy is associated with lower incidence of obesity at later age. METHODS: Parents of 399 infants, 9 to 15 months old, were interviewed and asked whether a pacifier was used consistently for ≥9 months. Body mass indexes at birth, 6 months, and on the day of interview were calculated. RESULTS: In all, 204 (51%) infants used a pacifier, and 195 (49%) were nonusers. More infants in the nonuser group were either overweight-40 (21%)-or obese-32 (16%)-than in the user group-22 (11%) and 22 (11%), respectively ( P = .003). CONCLUSIONS: Pacifier use in infancy was associated with lower incidence of obesity at 9 to 15 months of age. Offering a pacifier can be protective against infantile obesity.

Possible Impact of Yearly Childhood Vaccination With Trivalent Inactivated Influenza Vaccine (TIV) on the Immune Response to the Pandemic Strain H1N1.

BACKGROUND: Annual vaccination of children against seasonal influenza with trivalent inactivated influenza vaccine (TIV) has shown to be beneficial. However, this yearly practice may have unintended effect. Studies have shown that infection with wild type influenza A viruses can stimulate protective heterotypic immunity against unrelated or new influenza subtypes. We hypothesized that a consequence of yearly TIV vaccination is lack of induction of heterotypic immunity against the recent H1N1 pandemic. METHODS: This was a retrospective case-control study. We reviewed the medical records of polymerase chain reaction-confirmed cases of 2009 H1N1 influenza infection in children 6 months to 18 years and a matched control group seen during the pandemic. RESULTS: We identified 353 polymerase chain reaction-confirmed H1N1 cases and 396 matching control subjects. Among the H1N1 group, 202/353 (57%) cases received a total of 477 doses of seasonal TIV compared with 218/396 (55%) in the control group who received a total of 435 doses. Seasonal TIV uptake was significantly higher in the H1N1 group 477/548 (87%) than in the control group, 435/532 (81%) (P = .017). CONCLUSION: Seasonal TIV uptake was significantly higher in H1N1-infected group. The finding suggests that the practice of yearly vaccination with TIV might have negatively affected the immune response against the novel pandemic H1N1 strain. Given the rarity of pandemic novel influenza viruses, and the high predictability of seasonal influenza occurrence, the practice of yearly influenza vaccination should be continued. However, the use of live attenuated intranasal vaccine, as opposed to TIV, may allow for the desirable development of a vigorous heterotypic immune response against future pandemics.

Effect of a preoperative gabapentin on postoperative analgesia in patients with inflammatory bowel disease following major bowel surgery: a randomized, placebo-controlled trial.

BACKGROUND: Postoperative pain management for patients with inflammatory bowel disease (IBD) can be challenging. These patients have a high tolerance to pain medication, and relative contraindications to the use of epidural analgesia, limiting the pain management options. We evaluated the effect of a single preoperative gabapentin dose on opioid consumption for patients with IBD undergoing abdominal surgery. Secondary outcomes were postoperative pain scores, opioid-related side effects, and patient's length of hospital stay. METHODS: Following Research Ethics Board approval and informed written consent, patients were randomly allocated into 2 groups receiving either 600 mg of oral gabapentin or placebo 1 hour before the surgery. A blinded anesthesiologist recorded pain scores at rest and movement twice daily for 2 postoperative days. Also recorded were opioid consumption, time of return of bowel function, time to discharge, and opioid-related side effects on the opioid-related symptom distress scale (ORSDS). RESULTS: Seventy-two patients completed the study. The difference in opioid consumption (P = 0.4169) and pain scores measured at rest and movement on all 4 postoperative visits was not statistically significant. There was no significant difference between gabapentin and placebo on all the 11 symptoms reported on the ORSDS. There was a slight increase in length of hospital stay in the placebo group, but the return of bowel function was similar between the groups. CONCLUSIONS: This study examined the effect of a single preoperative administration of gabapentin in patients with IBD undergoing major bowel surgery. Our results suggest a single preoperative oral dose of gabapentin 600 mg does not reduce postoperative pain scores, opioid consumption, or opioid-related side effects.

Reviewing the follow-up care of pediatric patients' status post-hematopoietic stem cell transplantation for the primary care pediatrician.

BACKGROUND: Hematopoietic stem cell transplantation (HSCT) is a treatment modality for many oncologic as well as non-oncologic disorders. Although the side effects of different chemotherapy regimens have been well studied by several oncology consortiums, limited data is available regarding the late adverse effects of HSCT. Furthermore, pediatric-focused post-HSCT follow-up guidelines for primary care pediatricians do not exist. OBJECTIVE: To provide a summary of the most common late adverse effects of HSCT and give the primary care pediatrician guidance and evidence-based information for the screening and management of this patient population. DESIGN: The literature was searched using PubMed using keywords, including pediatric bone marrow transplant, hematopoietic stem cell transplant guidelines, pediatric bone marrow transplant guidelines, and pediatric bone marrow transplant immunizations. The most relevant articles out of the hundreds of results were reviewed. RESULTS: Based on 9 review articles from the Pediatric Clinics of North America and 3 articles from the Biology of Blood and Marrow Transplant Journal as well as their original references, a summary of the most common late adverse effects after HSCT was constructed. Pediatric HSCT patients have a high incidence of late adverse effects, with 93% of survivors having at least 1 late adverse effect after 7 years of follow-up. CONCLUSION: Late adverse effects after pediatric HSCT are common and require close screening and monitoring, which can be done by the primary care provider along with the oncologist.

"Don't call me 'mom'": how parents want to be greeted by their pediatrician.

BACKGROUND: Physician-patient interaction during the medical interview is essential in establishing the rapport necessary for a successful relationship. Physicians are generally encouraged to shake hands with patients, address patients by name, and identify themselves. OBJECTIVE: To define parents expectations for greetings by pediatricians and to determine the frequency with which these expectations are met. Design and methods. A total of 100 parents visiting the General Pediatric Clinic at Children's Hospital of Michigan were recruited. Parents were interviewed at the end of their medical encounter to determine expectations for greeting by their doctor. They were questioned about preferences for shaking hands, the doctors' use of their names, and the way doctors should introduce themselves. They were then asked if the experience at this visit conformed to these expectations. RESULTS: Overall, 81% of the parents were the children's mother and 86% were African-American. Over 80% of parents expected physicians to shake hands; 70% of residents and 66% of attendings did. 88% of parents wanted to be addressed by their names; only 14% of residents and 24% of attending physicians did so. All of the parents wanted the physicians to introduce themselves; 84% of residents and 93% of attendings did so. CONCLUSIONS: Physicians neither shook hands with many parents who expected it, nor did they address parents by their last names. About 90% of physicians introduced themselves. These disappointingly low results may predispose to parent dissatisfaction. Attending physicians need to teach these small, but important features, and to model them as well.

Prurigo nodularis in a 9-year-old girl.

A 9-year-old African-American female with a known history of atopic dermatitis presented for evaluation of an intensely pruritic nodular rash on both upper and lower extremities, buttocks, and lower abdomen for more than 1 year. The patient had been treated with several medium-potency topical steroids and antipruritics without appreciable improvement. After considering and excluding other differential diagnoses, the diagnosis of prurigo nodularis (PN) in association with atopic dermatitis was made. Prurigo nodularis usually occurs in middle-aged and older persons and is rarely seen in the pediatric population. The onset of PN in the case presented is considerably earlier than what has been described in literature. The etiology of the disorder is unknown. The management of prurigo nodularis is usually challenging for both patients and treating physicians. Frequently, combinations of several medications or modalities are used in an attempt to control disease activity. Overall, PN is a benign condition in children, particularly when it is associated with atopic dermatitis. It does not increase mortality; however, it can cause significant morbidity in untreated patients.

The natural history of pityriasis rosea in black American children: how correct is the "classic" description?

OBJECTIVES: To delineate the natural history of pityriasis rosea in black children and to compare our findings with those of the American, European, and African literature on pityriasis rosea. Textbook and journal article descriptions of pityriasis rosea usually offer information about the presentation and clinical course of this condition in white patients. DESIGN: Prospective observational study. SETTING: The general pediatric clinic, adolescent clinic, and emergency department of Children's Hospital of Michigan, Detroit, from June 2003 through May 2005. PATIENTS: We followed up 50 black children with pityriasis rosea from the time of diagnosis through follow-up visits at 1, 2, and 4 weeks. Detailed observations were made and digital photographs taken at each visit. MAIN OUTCOME MEASURES: Duration of illness and pigmentary sequelae. RESULTS: Similarities with the medical literature were found regarding season of onset and prevalence of pruritus and of a herald patch. Our patients had more frequent facial involvement (30%) and more scalp lesions (8%) than usually described in white populations. One third had papular lesions. The disease resolved in nearly one half of patients within 2 weeks. Residual hyperpigmentation was seen in 48% of patients. Hypopigmentation developed in 29% of patients with purely papular or papulovesicular lesions. CONCLUSIONS: Pityriasis rosea in black children differs in several ways from textbook descriptions. Physicians may use this information to better counsel patients about the course and potential sequelae of this condition.

Azithromycin does not cure pityriasis rosea.

OBJECTIVES: Pityriasis rosea (PR) is a common skin disorder in children. Its cause is unknown. A recent publication reported a 73% cure rate in patients with PR after treatment with erythromycin. To duplicate this result using a drug with fewer adverse effects and greater biological half-life, we set out to study the effect of azithromycin on PR. Azithromycin is an azalide antibiotic with a spectrum of antimicrobial activity very similar to that of erythromycin. DESIGN: We randomly assigned 49 children with PR to receive either azithromycin (12 mg/kg per day, up to a maximum of 500 mg/day) for 5 days or a similar-appearing placebo. Study physicians were blinded to patients' treatment type. Two pediatricians had to agree on the diagnosis of PR before patients could be enrolled. Subjects were seen at follow-up visits 1, 2, and 4 weeks after starting treatment. OUTCOME MEASURES: We measured the appearance of new lesions and resolution of lesions. RESULTS: Rates of cure and of partial resolution were similar in the azithromycin and placebo groups. CONCLUSION: Azithromycin does not cure PR.

Immersion scald burns and the ability of young children to climb into a bathtub.

INTRODUCTION: Immersion scald burns in children are often suspicious for neglect or abuse. The history that a child climbed into a tub previously filled with hot water by the parent is common. The child's ability to climb into such a tub is a major factor in determining the reliability of the history. METHODS: A standard bathtub was installed in an examination room at a pediatric clinic in a children's hospital. Foam mats were placed in and outside of the tub. Toy boats were placed in the back of the tub. Children were selected if they were between 10 and 18 months of age, born at term, and had no past or present medical condition that could be expected to have affected their fine or gross motor or central nervous system development and had a normal Denver Developmental Screening Test within the past 3 months. The parent placed the child in a standing position with the child holding onto the front of the tub. Parents encouraged the child to climb into the tub and get the toys. The child's efforts were videotaped. Children were allowed 5 minutes to climb, depending on their attention span and tolerance. RESULTS: Of 176 children in the study, 62 (35%) climbed into the tub. One fourth climbed in head first, and the rest climbed in sideways. CONCLUSIONS: Our study may have underestimated children's climbing abilities because of the absence of a shower curtain to help with balance and the distracting presence of strangers. The diagnosis of abuse is in part based on a described mechanism being inconsistent with the observed pattern of injury. This has severe repercussions for the child and his or her family. Our study brings into question previously held beliefs that these injuries could only be sustained by direct immersion.

Screening for domestic violence in a general pediatric clinic: be prepared!

OBJECTIVES: Exposure to violence, particularly domestic violence (DV), negatively affects children's physical, emotional, and cognitive well-being. The American Academy of Pediatrics recommends routine DV screening of female caretakers of pediatric patients. Few reports of screening in pediatric practices exist, and none have reported outcomes from a resident-run urban academic center. We set out to determine whether the use of the Partner Violence Screen (PVS) increases detection of DV and to test the mechanics of implementing large-scale DV screening in a busy, pediatric residency training clinic. METHODS: Using the PVS, we screened a sample of consecutive female caretakers/guardians of children seen for pediatric care in the general pediatric clinic of Children's Hospital of Michigan from March 1, 2002, through February 28, 2003. Positive screens obtained during the study period were compared with the number of DV referrals received by the clinic social workers from January 1, 2001, through December 31, 2001, before PVS screening began. To test the mechanics of screening, we also analyzed the number of forms returned blank or marked "no opportunity to screen" in the last 8 months of the study period. RESULTS: In the 12 months before use of the PVS, our social work department received 9 referrals because of DV from the general pediatric clinic, among a total of 5446 caretakers/guardians bringing 6380 children for a total of 13,576 patient care visits. In contrast, the social work department received 164 referrals because of positive screening results among 5445 caretakers/guardians bringing 7429 children for 17,346 patient care visits in the 12-month study period after introduction of the PVS. Fourteen of 164 positive PVSs were found to involve nondomestic violence perpetrated by nonpartners or violence with the patient as the victim, not the mother or female caretaker. A total of 150 PVSs involved true DV. The difference in identification of DV with the PVS, compared with the rate before its introduction, was highly significant. The positive predictive value for the PVS was 91.5%, and the identified prevalence rate was 3.7%. In the last 8 months of the study period, 6301 of 8055 PVS forms (78%) were completed; 1754 of 8055 PVS forms (22%) were left blank, but it was not possible to determine whether these represented duplicate screening forms for instances in which the mother or female caretaker had brought >1 child for care. CONCLUSIONS: Formal screening for DV with the PVS in this study setting of a busy, urban, academic, general pediatric clinic appeared to be very successful, in terms of increasing referrals and documentation of previously unrecognized DV situations. This increase signals the need for resources (time and/or social work services) to provide appropriate referral services. The PVS identifies nonpartner violence occasionally.

Surgical reduction and stabilization for repair of femoral capital physeal fractures in cats: 13 cases (1998-2002).

OBJECTIVE: To evaluate anatomic reduction and surgical stabilization of femoral capital physeal fractures in cats. DESIGN: Retrospective study. ANIMALS: 13 cats. PROCEDURE: Medical records of cats with unilateral or bilateral femoral capital physeal fractures evaluated from 1998 to 2002 were reviewed. Age and weight of cats at the time of surgery; breed; sex; concurrent injuries; severity of lameness before and 1, 2, 4, 6, and 8 weeks after surgery; the amount of fracture reduction achieved and number of Kirschner wires (K-wires) used; degree of degenerative joint disease of the hip joint and lysis of the femoral neck and head observed after surgery; whether K-wires were removed after surgery; and complications after surgery were evaluated. RESULTS: Thirteen cats with 16 capital physeal fractures were identified. There was significant improvement in the severity of clinical lameness in all cats from weeks 1 through 4 after surgery. There was no correlation between the scores of the individuals who evaluated radiographs for fracture reduction and placement of K-wires. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggested that surgical stabilization and repair of femoral capital physeal fractures facilitate a short recovery period and a good prognosis for return to normal function in cats.
