    Notes: Summary The conventional hiatal hernia repair is a tension repair. Large defects such as those associated with an intrathoracic stomach can have a high rate of recurrence resulting in esophageal symptoms and in some instances gastric strangulation. Numerous additive procedures are used to secure the stomach in the abdominal cavity including mesh buttressing, fundoplication, anterior abdominal wall gastropexy and fundus diaphragmatic suture fixation. The optimal repair is unknown primarily because crura closure failure is poorly understood. A literature review was used to determine the proven causes of hiatal hernia recurrence. Early postoperative vomiting, surgeon inexperience, short esophagus and no crus closure are documented causes. In a series of 19 hiatal hernia recurrence repairs from our institution, additional causes such as suture pull-out and trauma have been established as additional mechanisms of recurrence. Increased intra-abdominal pressure associated with motor vehicle accidents was the precipitating factor in 2/19 patients. Suggested methods for prevention of hiatal disruption and resultant hernia are proposed which include: a postoperative antiemetic regimen, restricted activity in the early postoperative period, an assessment technique for the short esophagus when utilizing a laparoscopic approach, crus closure calibration and inclusion of the diaphragmatic fascia when performing hiatal closure for large paraesophageal hernias and the short esophagus.

    Notes: Abstract To identify incidence of antibody to hepatitis C virus among 265 male prison inmates, we assayed paired serum specimens obtained at intake in 1985–1986 with follow-up specimens in 1987. Intake prevalence was 38 percent. Seroincidence was 1.1/100 person years in prison. This finding might reflect saturation of high-risk subgroups or possibly reduced frequency of exposures following incarceration.

    Notes: Abstract Peripheral blood lymphocytes (PBL) were obtained from five patients with the acquired immune deficiency syndrome (AIDS), six homosexual males with lymphadenopathy, and five normal heterosexual controls. Modulation of virus-specific immunity was assayedin vitro by measuring the lymphocyte blastogenic response and the production of lymphokine (leukocyte inhibition factor; LIF) by PBL stimulated with herpes simplex virus (HSV) or cytomegalovirus (CMV) antigens in the presence or absence of interleukin-1 (IL-1) and interleukin-2 (IL-2). PBL from the control and lymphadenopathy subjects responded to both antigens in the lymphocyte transformation assay (LT) measured on day 7, and the responses were significantly enhanced in cultures grown in the presence of antigen and IL-2 (1 U/ml). PBL from the AIDS patients were unresponsive, but responsiveness was restored by the addition of IL-2. The addition of IL-1 (0.02 µg/ml) to antigen-stimulated PBL cultures failed to enhance the proliferative responses in all three study groups. LIF production was assayed in the supernatants from day 1 PBL cultures. LIF was not produced by PBL from AIDS patients grown in the presence of viral antigens, whereas three of five patients from the lymphadenopathy group, and three of five control subjects gave rise to positive responses. The addition of IL-1 to the antigenstimulated cultures enhanced LIF production in the control and lymphadenopathy groups but not in the AIDS patients. The addition of IL-2 did not modulate LIF production by antigen-stimulated PBL from the control oR AIDS patients while suppressing the LIF response of the similarly stimulated PBL from the lymphadenopathy patients.

    Notes: Abstract One theory of the pathogenesis of Crohn's disease is that rather than being caused by a unique environmental agent, it is the result of an abnormal immune response in the gastrointestinal tract. Recent studies indicate that Crohn's disease in its early stages is frequently associated with the presence of circulating antigen-non-specific suppressor T cells. Such T cells are also found in experimental inflammation caused byChlamydia organisms in the gastrointestinal tract of nonhuman primates. Taken together, these data suggest that the suppressor T cells are markers of an underlying and persistent, antigen-specific immune response to an as yet unidentified antigen or set of antigens. We postulate that this underlying antigen-specific response is the result of a primary immunoregulatory abnormality involving an imbalance between the effects of antigen-specific helper and suppressor T cells which recognize a common antigen or antigens present in the mucosal environment.
