The normal appearance of CT myelograms

The cuticle of adults ofNippostrongylus brasiliensishas been described using histological, histochemical and ultrastructural techniques.The cuticle has the following layers: an outer triple-layered membrane; a single cortical layer; a fluid-filled layer which is traversed by numerous collagen fibrils; struts which support the fourteen longitudinal ridges of the cuticle and which are suspended by collagen fibrils in the fluid-filled layer; two fibre layers, each layer apparently containing three layers of fibres; and a basement lamella.The fluid-filled layer contains haemoglobin and esterase.The muscles of the body wall are attached to either the basement lamella or to the fibre layers of the cuticle.The mitochondria of the hypodermis are of normal appearance.The longitudinal ridges of the cuticle appear to abrade the microvilli of the intestinal cells of the host.Possible functions of the cuticle are discussed.I wish to thank Dr P. Tate, in whose department this work was done, for helpful suggestions and criticism at all stages of this work, and Mr A. Page for technical assistance. I also wish to thank Professor Boyd for permission to use the electron microscope in the Department of Anatomy.

SummaryA double-blind placebo controlled trial of Mucodyne (carbocisteine, Berk Pharmaceuticals), Actifed (triprolidine HCI and pseudoephedrine HCI, Wellcome) and combined Mucodyne and Actifed in the treatment of middle-ear effusions is reported. The trial was undertaken to assess whether either preparation, alone or in Combination, would reduce the number of children requiring surgical treatment for this condition. No statistical difference between the various groups in avoiding surgical treatment with Mucodyne was associated with a significantly greater number of ears restored to a normal appearance and middle ear function as measured by tympanometry. All patients relapsing after surgery belonged to the groups receiving placebo, Actifed or the combination of Mucodyne and Actifed prior to the operation.

Surgical Corrections

AbstractCongenital ear anomalies are associated with psychological morbidity. Ear deformities can usually be corrected by nonsurgical techniques such as splinting or molding in the neonatal period, initiated before 6 weeks. Without early corrections, many will require otoplasty during childhood. We introduce a novel silicone-based custom mold technique for congenital ear anomalies. The highly malleable silicone was pushed into every part of the auricle, enabling the auricle to remain in the desired shape, with new molds made weekly. Of 31 newborns (18 males, 13 females), 54 ears were treated. Average age at treatment initiation was 26.8 days. The mean treatment duration was 43.2 days, with a median of 28 days. Normal appearance and parent's satisfaction were achieved in 30 patients with 49 deformed ears and also in four newborns older than 6 weeks. Three concha type microtia in two patients achieved great improvements and parents' satisfaction. No complications were reported. Marked aesthetic improvements and normal appearance were achieved for all deformed auricles treated, and improvements in the concha type microtia will partially alleviate future surgical corrections. The results are not inferior to other techniques. The advantages are as follows: cost-effective, time-saving, simple to master, no need for hair shaving, and easy use for parents. Patients older than 6 weeks of age achieved normal auricle appearance, enabling the correction in older newborns. Custom made silicone auricle molding offers a simple nonsurgical technique for correcting congenital ear anomalies, alleviating the need for future surgical corrections.

Incomplete Septal Cirrhosis

Abstract Context.—Cirrhosis is widely regarded as being irreversible. Recent studies have demonstrated that fibrosis may decrease with time in humans and experimental animals if the disease activity becomes quiescent. The histologic appearance of regressing cirrhosis in the human has not been described in detail. Objectives.—To define histologic parameters that indicate regression of cirrhosis and to provide an interpretation of how regression occurs from a histologic point of view. Design.—A patient who underwent a series of biopsies that showed apparent regression of hepatitis B cirrhosis is presented. In addition, 52 livers removed at transplantation having cirrhosis or incomplete septal cirrhosis were graded for histologic parameters that suggest progression or regression of fibrosis. Progression parameters were steatohepatitis, inflammation, bridging necrosis, and piecemeal necrosis. The regression parameters (collectively called the hepatic repair complex) were delicate perforated septa, isolated thick collagen fibers, delicate periportal fibrous spikes, portal tract remnants, hepatic vein remnants with prolapsed hepatocytes, hepatocytes within portal tracts or splitting septa, minute regenerative nodules, and aberrant parenchymal veins. Results and Conclusions.—Regression parameters were found in all livers and were prominent in the majority. Livers with micronodular cirrhosis, macronodular cirrhosis, and incomplete septal cirrhosis demonstrate a histologic continuum. A continuum of regressive changes was also seen within individual livers. These appearances allow one to understand visually how fibrous regions of hepatic parenchyma can be returned toward a normal appearance. Many examples of incomplete septal cirrhosis could be the product of regressed cirrhosis.
