Effect of anaerobic cecal microflora and dietary lactose on colonization resistance of layer chicks to invasive Salmonella enteritidis.

The effect of oral inoculation with anaerobic cultures of cecal microflora and providing lactose in the feed on colonization resistance to invasive Salmonella enteritidis was evaluated in newly hatched leghorn chicks. Salmonella colonization of the ceca, tissue invasion and organ colonization, horizontal transmission, and seroconversion were significantly decreased (P less than 0.01) in chicks inoculated with cecal flora.

Comparison of the efficacy of cultures of cecal anaerobes as inocula to reduce Salmonella typhimurium colonization in chicks with or without dietary lactose.

The ability of anaerobic cultures from mature chicken cecal material stored at -70 C for 1 or 10 mo to reduce Salmonella typhimurium colonization of the ceca of young chicks was evaluated. Chick treatments consisted of per os inoculation with anaerobic cultures from the cecal materials and providing or not providing the chicks dietary lactose. Chicks were challenged per os at 3 days of age with 10(6) S.

Intracloacal Salmonella typhimurium infection of broiler chickens: reduction of colonization with anaerobic organisms and dietary lactose.

The combined effect of treatments with dietary lactose plus anaerobic organisms on cecal colonization of broiler chicks by Salmonella typhimurium was evaluated. Chickens treated with a combination of anaerobic organisms and 7% dietary lactose were resistant to cecal colonization by S. typhimurium.

Effect of dietary lactose on Salmonella colonization of market-age broiler chickens.

The effect of providing lactose in feed and inoculation with volatile fatty acid-producing anaerobic cultures (AC) of cecal flora on Salmonella typhimurium colonization was evaluated in broilers. One-day-old chicks were divided into four groups and provided 1) no lactose, no AC; 2) AC, no lactose; 3) AC and lactose on days 1-10; or 4) AC and lactose on days 1-40. All groups were challenged per os with 10(6) Salmonella on day 3 and with 10(8) Salmonella on day 33.

Biological control of Salmonella typhimurium in young chickens.

The effect of dietary lactose and anaerobic cultures of cecal microflora of mature chickens on the colonization of young broiler chickens by Salmonella typhimurium was evaluated. Newly hatched chicks were given either no treatment (controls), anaerobic cecal cultures, lactose (2.5%) in the drinking water, or both anaerobic cultures and lactose.

Effect of dietary lactose on cecal pH, bacteriostatic volatile fatty acids, and Salmonella typhimurium colonization of broiler chicks.

One-day-old broiler chicks were inoculated with volatile fatty acid producing cecal flora from adult chickens. The chicks were divided into four groups and provided 1) no lactose, 2) 2.5% lactose in water, 3) 5% lactose in feed, or 4) 10% lactose in feed, until 10 days of age.

Blood loss and haematological consequences related to nasal surgery.

A prospective study was carried out to compare blood loss from various types of nasal surgery, to investigate how accurately this loss was estimated during surgery and to find out how soon any losses were replenished. Blood loss during surgery was estimated, and by serial blood tests actual blood loss and continuing changes in haematological parameters were recorded. It was found that blood loss was highest when a nasal polypectomy and submucous resection were performed together and over the whole range of nasal surgery studied the actual blood loss was more than double the estimate during surgery.

Spontaneous dissection of the intrapetrous internal carotid artery.

Two cases of cervicocephalic arterial dissection of the intrapetrous carotid artery are described. One patient presented with intolerable objective pulsatile tinnitus, the other with a cerebral infarction. Both were successfully treated with anticoagulants.

Early nutrition intervention services for children with special health care needs.

Dietitians must be responsive to the changing needs of their clients and employers, to societal concerns, and to legal mandates. A recently passed amendment (PL 99-457) to the Federal Education for the Handicapped Act gives nutrition professionals the opportunity to have a voice in establishing nutrition policy and standards of care for young handicapped and high-risk children. The new law extends preventive services to children as young as 3 years of age, and Part H of the law provides financial incentives for states to provide services to children with special health care needs from birth to 2 years of age.

Anterior shoulder dislocation as a complication of surgery for burns.

An example of anterior dislocation of the shoulder resulting from the positioning of a patient for skin grafting of burns is presented. Complications of positioning patients prone and with their arms abducted and practical measures for their avoidance are discussed.

Surgery for otitis media with effusion in children and its relationship to parental smoking.

A study was conducted to ascertain whether there is any relationship between parenteral smoking and various factors in children undergoing surgery for otitis media with effusion. Information was recorded on 115 children admitted to hospital for grommet insertion. Details of parenteral smoking habits, previous surgery for otitis media with effusion and operative findings were noted.

Duplex Doppler sonography of renal transplants. Correlation with histopathology.

The correlation of histopathologic findings with duplex Doppler sonography (DDS) in 24 biopsies in 21 patients was studied. The resistive indices (RI) of the acute rejection group were statistically different (p = .04) from those that were negative for rejection or clinical controls.

Parental smoking and middle ear effusions in children.

A study was conducted on seventy children to ascertain any relationship between parental smoking and the presence of middle ear effusions in the children. Information was collected using a questionnaire, clinical examination and audiological tests. Both groups of children (with and without effusions) had similar age, sex and social class distributions.

Total laryngotracheal hypoplasia in a case of G syndrome.

We report a case of congenital hypoplasia of the larynx and trachea in the presence of an essentially normal cartilaginous structure. To our knowledge this abnormality is not recognised in the literature. Previously reported hypoplastic laryngeal anomalies have all shown anatomical defects ranging from clefts to atresia (Smith and Bain 1965, Gatti et al.

Kikuchi's disease--apparent malignancy of a neck mass.

We report a case of Kikuchi's disease presenting as cervical lymphadenopathy in an adolescent. The original histological diagnosis in this case was a metastatic neoplasm. We wish to highlight the importance of this rare condition because of its potential for mimicking malignancy.

Effect of chronic treatment with the calcium antagonist diltiazem in Duchenne muscular dystrophy.

We conducted a double-blind trial with the calcium antagonist, diltiazem (8 mg/kg/d), for 24 to 32 months in 22 boys with Duchenne muscular dystrophy, who were paired by functional activity and age. No adverse clinical or ECG effects of diltiazem were detected. In eight matched pairs, completing 28 months, manual muscle testing scores fell somewhat less in the diltiazem group (from 5.

Carcinoma of the fallopian tube.

Primary adenocarcinoma of the fallopian tube is a rare neoplasm that constitutes less than 1% of gynecologic malignancies. Although the triad of menorrhagia, leukorrhea, and pain is said to be pathognomonic, preoperative diagnosis of this lesion is most unusual. The radiographic appearance at hysterosalpingography has only rarely been described in the English literature previously.

In vivo glycocalyx expression by Staphylococcus aureus phage type 52/52A/80 in S. aureus osteomyelitis.

Osteomyelitic rat tibiae were examined by scanning electron microscopy for the extracellular glycocalyx of Staphylococcus aureus. S. aureus and fractured tibiae from normal rats were incubated together in vitro and examined similarly.

Pseudo defect of the spleen in an adolescent with fever of unknown origin.

The development of a pseudo defect in the spleen secondary to perforation of the bowel by a 17 cm lead pencil is described. The approach to diagnosis of a foreign body in the abdominal cavity is discussed.
