Applications for laparoscopy in general surgery.

Laparoscopy is a safe and accurate procedure within its capabilities. Laparotomy, although usually safe, continues to have complications and in certain contexts can be avoided by the appropriate use of laparoscopy. Recognition and application of its specific general surgical applications should stimulate its use and encourage a renewed interest in the technique.

Primordial cyst versus keratocyst.

The term primordial cyst was introduced in 1945 to identify the odontogenic cyst formed from enamel organ before calcification occurred as part of a classification based on development, structure, and radiographic appearance. The term odontogenic keratocyst was introduced in 1956 to describe cysts of the jaw exhibiting keratinization of their lining. Periodontal, dentigerous, primordial, residual, and gingival cysts may exhibit keratinized linings and can properly be identified as odontogenic keratocysts on the basis of their histologic appearance but may also be identified by their "developmental" designation. There is no justification for considering odontogenic keratocyst as a synonym for primordial cyst.

DiGeorge's or the III-IV pharyngeal pouch syndrome: pathology and a theory of pathogenesis.

Six new cases of the III-IV pharyngeal pouch syndrome were encountered at autopsy among 897 consecutive pediatric autoposies. All occurred in patients with conotruncal cardiac anomalies. The anatomic characteristics of the heart defect suggest a possible mechanism for the pathogenesis of this developmental anomaly. It is postulated that premature involution of the thyroidea ima artery, which is the principal embryonic blood source to the 3rd and 4th pharyngeal pouches and the ultimobranchial body, may be the critical event in the embryogenesis of the syndrome. Hemodynamic alterations in the course of anomalous morphogenesis of conotruncal anomalies may favor premature involution of certain vessels including the left 4th aortic arch and the thyroidea ima. Deficiencies of thymus, parathyroid glands and ultimobranchial tissue ("C" cells) may be the consequence of vascular deprivation during embryogenesis. These cases are discussed with regard to the proposed mechanism of pathogenesis and the influence of varying quantities of thymus upon peripheral lymphoid tissue. Both embryologic and clinical data support the possibility of a deficiency of ultimobranchial tissue. The range of minor and inconstant anomalies seen in patients with this syndrome is presented.
