A newborn baby with a complete or type III laryngotracheoesophageal cleft from larynx to carina was managed with a bifurcated endobronchial tube prior to complete reconstruction in one stage. To prevent pressure on the posterior suture line, a tracheostomy tube was constructed from a REA tube originally designed to use ...

A flexible fibreoptic laryngoscope was used to facilitate the passage of a long polyvinyl chloride tracheal tube into the left main bronchus during repair of a tracheo-oesophageal fistula situated near the carina in a patient in whom intubation with a double-lumen endobronchial tube was difficult. Close monitoring of neuromuscular transmission ...

Management of ingested foreign bodies (FB) is a common clinical problem. A 10-year experience of 101 foreign body ingestions is reported. The experience suggests that endoscopic removal of foreign bodies is curative for objects located in the cricopharynx or upper esophagus. Foreign bodies which pass into the stomach can be ...

Obesity is a common condition which has important effects on health status and longevity. This review examines the efficacy of treatments for both moderate and severe obesity. A plan of treatment combining diet, exercise, and behavioral strategies is outlined. Surgery and its complications are reviewed. Eight management issues, including rate ...

A three-step design procedure is developed for dielectric stacks which are required to be nonpolarizing for a given wavelength lambdar and angle of incidence theta 0,r, at which the reflectance Rr is prescribed. The method leads to solutions in which only three layer materials occur and can be applied for ...

Certain cases do not reveal themselves as urgent initially, and may appear to justify conservative management. In retrospect, the outcome of the case may reveal all too vividly the importance of early diagnosis and management. In this instance, the patient's own reluctance to submit to examination contributed to the decision ...

Strangulated right Richter's inguinal hernia of the cecum is relatively rare. A case of this unusual hernia was successfully managed with a wedge resection and closure of the infarcted bowel wall in conjunction with complementary tube cecostomy. The procedure is easy to perform and relatively safe and is therefore recommended ...

Thresholds were measured at 250, 500, 1,000, 2,000, 3,000, 4,000, 6,000, and 8,000 Hz in 20 normal adult ears and in ten ears from adults with varying amounts of ear-canal collapse. To alleviate the attenuation caused by ear-canal collapse, ear-canal inserts, postauricular pads, or circumaural cushions (Telephonics 510-020) were used ...

Investigation, assessment, and management of carcinogenic risks are not only scientific but also political responsibilities. In Canada, this becomes cumbersome, since local, provincial and federal policies are involved. The process also involves workers and management. This article outlines Canadian legislative experience, the principles involved, the methods of risk assessment, and ...

Having an accurate job description of family physicians is important to a number of audiences. There is a tendency to produce another content profile of family practice in response to every specific request for an accurate job description, rather than examining the existing profiles. We analyzed the amount of similarity ...

Senile dementia is an increasingly important disease in family medicine, because our population is growing old. Dementia can have many causes, some of which are reversible. Its definition varies with time, discipline, and country. Correctly diagnosing reversible dementing processes as early as possible may lead to reversal of an otherwise ...

A long-term follow up of a personal series of 79 second ear stapedectomies indicates that the procedure can be undertaken with minimal complications. No bilateral dead ears or vestibular disasters have occurred. The results were satisfactory in 87.5% of ears, and bilaterally symmetrical hearing with an air-bone gap of 30 ...

A comparison was made between a vertical tube rotor and a fixed angle rotor for isopycnic centrifugation of proteoglycans. In the vertical tube rotor, isopycnic gradient was achieved much faster than in the conventional fixed angle rotor. The use of a vertical tube rotor for isopycnic centrifugation shortens the time ...

Although the traditional management of aspiration of foreign bodies has been extraction with the open tube bronchoscope, an expanding array of these have now been removed with the flexible bronchofiberscope. Accidental introduction of a foreign body into the tracheobronchial tree is a poorly recognized, but potentially common hazard of topical ...

This article attempts to define the term 'occupational dermatitis'. A step by step approach to the management of possible occupational dermatitis is outlined under the following headings: Suspicion, Identification, Elimination or Reduction, and Treatment.Many other factors, in addition to the identification of occupational hazards, play a role in causation of ...

Foreign bodies of the ear should be removed by irrigation, suction, or forceps. General anesthesia may be necessary. Foreign bodies of the nose should be removed with suction or forceps, and sometimes intubation may be necessary. Most foreign bodies in the throat can be removed by use of a mirror ...

Techniques have been developed for the isolation of basal bodies with cilia attached or for the isolation of only basal bodies from the rabbit oviduct. Oviducts are removed, cut open, and placed in an extraction medium composed of 0.25 M sucrose, 0.001 M EDTA, 0.025 M KCl, 0.02 M Hepes ...

A total of 660 patients with ingested foreign bodies admitted to the general surgical services in two children's hospitals in Liverpool are reviewed. Endoscopic removal (205 cases) is recommended for all foreign objects impacted in the oesophagus, with the exception of rounded or blunt objects in the lower third, which ...

Biomechanics is a monthly newsmagazine aimed at those working in the fields of sports medicine, orthopaedic surgery, physical therapy, clinical athletic training, orthotics and prosthetics, podiatry, pedorthics, physiatry, rehab and occupational therapy. The newsletter includes peer reviewed articles that focus on treatment of joint and body injuries, geriatrics, rehabilitation, function ...

These guidelines have been produced by the Clinical Resource Efficiency Support Team (CREST, 2004). The guidelines include: rationale for nutritional support; legal and ethical aspects of nutritional support; routes of access for administration of enteral nutrition; management of the patient, enteral feeding tube and administration system; discharging a patient on ...

Axon hillocks and initial segments have been recognized and studied in electron micrographs of a wide variety of neurons. In all multipolar neurons the fine structure of the initial segment has the same pattern, whether or not the axon is ensheathed in myelin. The internal structure of the initial segment ...

Fowler's bacillus is one of several organisms which form a non-viable inclusion or parasporal body during the process of sporulation. This body is globular and may be as large as or larger than the spore. Its position in the cell is not random; the spore is terminal and the body ...

Colonies of Streptomyces coelicolor growing on cellophane and impression preparations from sporing colonies were stained for chromatin by the methods of Feulgen, DeLamater (1951), and Pi?chaud (1954). The chromatinic bodies of the substrate hyphae have a great variety of configurations. During the development of the spores, elongated chromatinic structures in ...

Toluidine blue, applied to frog sperm under appropriate conditions, inactivates specifically the sperm nucleus, leaving the extranuclear parts of the cell undamaged. Thus, the dye-treated spermatozoa stimulate eggs to cleave normally, but contribute no chromosomes to the resulting embryos, which develop as typical gynogenetic haploids. The concentration of dye required ...
