Knowledge and attitudes about otitis media risk: implications for prevention

OBJECTIVES: To investigate maternal knowledge and attitudes about otitis media (OM) risk, to estimate the prevalence of risk factors in the first year of life, and to identify barriers to the reduction of risk factors (eg, formula feeding, day care attendance, and exposure to passive smoke). METHODS: Questionnaires mailed to a systematic sample of 504 Minnesota women >/=18 years old identified through 1994 birth certificates. RESULTS: Eighty percent returned a completed survey. According to maternal report, 29% of infants (age 8 to 13 months) had recurrent OM (>/=3 episodes) and 2% had tympanostomy tubes. Forty-six percent attended day care, 29% had >/=1 smoking parent, and 49% breastfed for 相似文献   

Effect of the viable-yellow (A(vy)) agouti allele on skin tumorigenesis and humoral hypercalcemia in v-Ha-ras transgenic TGxAC mice

We previously reported that papillomas can arise from the follicular epithelium of v-Ha-ras transgenic TGxAC mice. Since the viable-yellow mutation (A(vy)) of the mouse agouti gene which regulates coat color pigmentation by acting within the micro-environment of the hair follicle has been shown to function as a tumor promoter in the liver, we hypothesized that it may also play a role in TGxAC skin tumorigenesis. Endogenous agouti protein product was detected in the outer root sheath of anagen hair follicles following plucking of the hair shaft, but not in the interfollicular epithelium, in TGxAC mice on an FVB/N genetic background. It was also detected in papillomas from these mice produced by 12-O-tetradecanoylphorbol-13-acetate (TPA) treatment or plucking. Expression of the A(vy) allele in the v-Ha-ras transgenic TGxAC mouse line results in an approximately 2-fold increase in papilloma development compared with controls which did not carry the A(vy) allele following twice-weekly treatment with 1.25, 2.5 or 5.0 microg TPA. In addition, TPA-treated, papilloma-bearing F1 mice which carried the A(vy) allele, but not F1 mice which did not carry the A(vy) allele, exhibited a syndrome of humoral hypercalcemia mediated by parathyroid hormone-related protein (PTHrP) that led to weight loss, hypercalcemia and hypophosphatemia. Thus, we conclude that the A(vy) allele can influence the development of skin tumors and PTHrP-mediated humoral hypercalcemia in v-Ha-ras transgenic TGxAC mice.      

Editorial Commentary: SLAP Repair—The Anterosuperior Portal for Anchor Placement Is Best

The anterosuperior rotator interval portal for SLAP repair anchor placement is the perfect balance between obtaining the proper anchor trajectory and respecting the rotator cuff integrity.     

Application of osteopathic manipulative treatment to a patient with unremitting chest pain and shortness of breath undergoing “Rule-Out Myocardial Infarction” protocol for one week

Chest pain and shortness of breath are both common complaints of patients presenting to an emergency room (ER) or urgent care facility. A 67-year-old married white female was seen in the ER complaining of chest pain and shortness of breath. Our education and training has us admit these patients where they may be monitored and assessed according to protocols developed to rule-out serious etiologies. Accordingly, the patient was admitted to the cardiac care unit and placed on the “Rule-Out Myocardial Infarction” protocol. The patient’s symptoms persisted despite adherence to rigorous diagnostic and therapeutic regimens and which stymied attempts to arrive at a definitive diagnosis and provide care. The case presented here demonstrates how an osteopathic approach can enable us to provide appropriate care and resolve some problems that appear to be otherwise unremitting. There is potential for savings in terms of actual costs and utilization of resources. The use of an osteopathic structural exam identified an abnormality that could be easily treated with Osteopathic Manipulative Treatment (OMT), which completely resolved the patient’s presenting complaints. Had this been done earlier in the course of managing this patient, preferably as part of the admission work-up, the patient’s confinement would have been drastically reduced, and repeated expensive tests would not have had to have been performed. The application of OMT to reducing patient morbidity is instructive of the efficacy of the osteopathic approach in this case and suggests that further research is warranted.

Analrandkarzinom bei Rezidivrektumprolaps

Surgery for third degree rectal prolapse and its sequelae in the elderly still represents a challenge. We report the case of a 92-year-old patient with a history of recurrent third degree rectal prolapse of at least 2?years?? standing. The patient had already had abdominal rectopexy for the same disease 16 years previously. In addition, she now suffered a large perianal ulcer. The patient underwent abdominal rectopexy and biopsy from the ulcer. The histology from the ulcer margin revealed a squamous cell anal cancer. In conclusion, we postulate that the anal cancer can be considered as a consequence of the long-standing rectal prolapse. The patient had previously been informed by her family practitioner that the prolapse could not be operated due to her advanced age. This case highlights that a third degree rectal prolapse should be operated regardless of age in order to avoid late sequelae.     

Adenosine bronchial provocation with computerized wheeze detection in young infants with prolonged cough: correlation with long-term follow-up

BACKGROUND: Chronic cough in babies is often associated with bronchial hyperreactivity (BHR). The objective documentation of BHR in babies is difficult, and acoustic methods have been described (provocative concentration of a substance causing wheeze) for conducting bronchial provocation tests (BPTs). We conducted a study to evaluate automatic computerized wheeze detection (CWD) in determining BHR in young infants with prolonged cough, and its correlation with the subsequent development of wheezing. METHODS: Infants aged < 24 months with prolonged cough (ie, > 2 months) underwent acoustic BPTs with the response determined by CWD and auscultation by a physician. Telephone interviews with parents were conducted after 1 month and yearly for the next 3 years. RESULTS: A total of 28 infants who were 4 to 24 months old with prolonged cough were included in the study. Twenty of these infants (71.4%) had BHR as determined by a positive acoustic BPT result. In 11 of these 20 tests, the CWD occurred earlier, and in 9 tests it occurred at the same step as auscultation by a physician. Rhonchi or whistles often preceded wheezes. Seventeen of the 20 patients with BHR completed 3 years of follow-up. Of these, 14 had recurrent episodes of wheezing and shortness of breath, and 3 were well. Six of the eight adenosine-negative patients completed 3 years of follow-up and had no symptoms of BHR. CONCLUSIONS: Acoustic BPT is a technically feasible test for the detection of BHR in young infants. CWD provides an earlier detection of wheeze than stethoscope auscultation. In our group of infants, a positive acoustic BPT result had high correlation with symptoms compatible with BHR over the next 3 years.     

Intestinal pseudo-obstruction as an initial presentation of systemic sclerosis in two children

Two children are reported in whom intestinal pseudo-obstruction was the initial manifestation of systemic sclerosis. Gastrointestinal symptoms and skin changes resolved or improved in both children following treatment with prednisone and penicillamine (case 1) or methotrexate (case 2), although radiological changes of the gastrointestinal tract persisted at 3 and 2 yr of follow-up, respectively.      

Campylobacter enteritis: clinical and epidemiologic features.

Campylobacter fetus subspecies (ssp.) jejuni has been recently recognized to cause diarrheal disease in man. To assess its importance as an enteric pathogen, we prospectively studied 514 patients with diarrhea. Campylobacter fetus ssp. jejuni was isolated from the feces of 26 patients (5%) and seven of 11 of their symptomatic household contacts. This organism was isolated from the feces of only one of 18 asymptomatic household contacts and not at all from 157 other healthy persons. Seventeen of 20 patients from whom C. fetus ssp. jejuni was isolated from fecal culture showed at least a fourfold rise in specific IgG titers. Review of 35 cases of campylobacter enteritis identified a typical clinical syndrome with acute onset of diarrhea, abdominal pain, fever, and constitutional symptoms. Stool examination revealed blood in 60% and polymorphonuclear leukocytes in 78% of patients. Epidemiologic investigation strongly suggested an external source for the infection in 22 of 35 patients.
