Abstract
Peritoneal carcinomatosis originating from gastric/gastroesophageal junction cancer (GC-PC) occurs in a defined subset of gastric cancer patients with unique clinical, pathologic, molecular and immunologic characteristics that create significant obstacles to effective treatment with modern therapy. Although systemic chemo- and immuno- therapy have yielded disappointing results in GC-PC, recent advances in the characterization of GC-PC and peritoneal immune biology present new opportunities for targeted therapeutics. In this review article, we discuss the distinct properties of GC-PC and the peritoneal immune environment as they pertain to current and investigative treatment strategies. We discuss pre-clinical studies and clinical trials relevant to the modulation of the peritoneal environment as a therapeutic intervention in GC-PC. Finally, we present a road map for future combinatorial strategies based on the conception of the peritoneal cavity as a bioreactor. Within this isolated compartment, prevailing immunosuppressive conditions can be altered through regional interventions toward an adaptive phenotype that would support the effectiveness of regionally delivered cellular therapy products. It is hoped that novel combination strategies would promote efficacy not only in the sequestered peritoneal environment, but also via migration into the circulation of tumor-reactive lymphocytes to produce durable systemic disease control, thereby improving oncologic outcome and quality of life in patients with GC-PC.

Abstract
Premature birth in conjunction with extremely low birth weight (<1 kg, ELBW) is associated with insulin resistance and increased cardiometabolic health risk compared to birth at full term with normal birth weight (NBW). However, little is known regarding the biologic mediators of these effects. Abdominal and ectopic lipid accumulation is linked to insulin resistance and metabolic dysfunction, yet whether ELBW survivors are predisposed to aberrant lipid deposition in adulthood is unknown. We used magnetic resonance imaging in a cohort of 16 NBW and 29 ELBW participants to determine if ELBW survivors have differences in pancreatic, hepatic, subcutaneous and visceral fat distribution compared to NBW participants. ELBW individuals had a higher proportion of liver and pancreatic fat compared to NBW subjects (P < 0.05). Abdominal subcutaneous fat, but not visceral fat, area was higher in ELBW survivors compared to NBW individuals. In multivariate analyses, tissue fat measures were most highly related to BMI and sex, but not preterm birth. This work highlights that fat deposition is enhanced in adults born preterm and suggests that ectopic fat accretion driven by their relatively greater adiposity may contribute to the higher rates of metabolic dysfunction seen in ELBW survivors.

Abstract
The approach of a new millenium provides us, as rhinoplasty surgeons, the opportunity to reflect on where we are and where we are going. Aesthetically, there are several trends that are evident today. The first is the desire for a natural, unoperated appearance to the final rhinoplasty result. Second, is that our patient population continues to be more racially diverse; Caucasian normative standards of facial analysis are no longer sufficient. What is required is a broader understanding of ethnically specific facial features. Third, the standard values of facial and nasal analysis are derived from population means. If we desire to create beauty, these standards may not be adequate. Beauty is an ill-defined concept that is obvious to the observer and recognized cross-culturally, however, it is difficult to quantify. To consistently achieve beautiful rhinoplasty results, we must start with an understanding of what our aesthetic ideals should be. This has yet to be satisfactorily defined for all racial groups and remains a challenge for the future.

Abstract
The treatment of laryngeal and hypopharyngeal hemangiomas is indicated when they are symptomatic, causing dysphagia, recurrent bleeding, or airway obstruction. These tumors are found in the glottis, supraglottic larynx, and hypopharynx. Histologically, they are considered as mixed or cavernous-type hemangiomas. By utilizing a glass slide to compress the lesion, its thickness and blood flow are reduced. The tumor can then be laser-photocoagulated with less energy, with the glass slide used as a laser platform. These conditions optimize the benefits of laser ablation while minimizing the adverse heat sink effects to the surrounding healthy tissue. We present three patients with hemangiomas of the larynx and hypopharynx who were treated with this technique. The details of the technique in each case will be presented with the objective of improving the care of these unusual and challenging tumors.

Abstract
Bone marrow transplantation for the treatment of leukemia is increasingly successful in rendering patients disease free. However, it has become evident that the associated severe immunosuppression predisposes this population to an increased risk for other neoplastic disorders. We report on six patients in whom non-Hodgkin's lymphoma of the tonsillar region developed within 5 months after T-cell-depleted bone marrow transplantation for the treatment of leukemia at Memorial Sloan-Kettering Cancer Center from October 1990 to October 1992. These patients initially had what appeared to be infectious exudative pharyngitis/tonsillitis; however, they did not improve with medical therapy. Because of the persistence of pharyngitis/tonsillitis in association with cervical lymphadenopathy and odynophagia, the patients underwent definitive biopsy in the form of tonsillectomy, cervical lymph node biopsy, or both. Histopathologic review revealed non-Hodgkin's lymphoma. An association with Epstein-Barr virus has been noted in five of these patients. This article is aimed at alerting the clinician to consider the diagnosis of lymphoma in a patient with persistent pharyngitis/tonsillitis despite adequate medical therapy after bone marrow transplantation.

Abstract
Factors controlling glutathione metabolism may govern sensitivity to chemotherapeutic agents such as cisplatin. Using a battery of cell lines derived from previously untreated head and neck squamous cell carcinomas, we examined cisplatin resistance relative to (a) glutathione-S-transferase (GST)-pi gene amplification and expression, (b) basal and inducible GST-total and GST-pi enzymatic activity, and (c) cellular levels of reduced glutathione (GSH). Using Southern blot analysis and northern blot hybridization, no relationship between GST-pi gene amplification, mRNA expression and drug resistance could be identified. Despite the capacity of cisplatin to induce GST enzyme activity, the response was variable and unrelated to cisplatin responsiveness. However, an inverse relationship between GSH levels and cisplatin sensitivity was identified. To further clarify these effects, cells were treated with S-allyl cysteine (SAC), a thioallyl derivative isolated from garlic (Allium sativum), which altered cellular GSH in a biphasic manner. Pretreatment with SAC to lower cellular GSH levels followed by exposure to cisplatin significantly enhanced the cytotoxic effects of cisplatin, while SAC alone had no effect on cell growth.

Abstract
The efficacy and associated morbidity and mortality of gastrostomy (G) versus nasogastric (NG) tube decompression after gastric surgery were analyzed in a review of 100 patients. Age, sex, and risk factors were homogeneously distributed between the two groups, while perforated ulcers and emergency operations were more common in the G group. A gastrostomy did not completely eliminate the need for NG tube decompression in the G group. Postoperative morbidity was similar in the two groups, with the exception of an increased incidence of atelectasis in the elective NG group and increased mortality in the emergency G group. There was also a significant increase in length and cost of hospitalization in the emergency G group compared with emergency NG patients. Gastrostomy does not appear to offer any significant advantage over nasogastric decompression after gastric surgery and should be limited to special cases.

Abstract
The purpose of this study was to determine whether or not thromboxane A2 (TXA2) was necessary or sufficient for the development of end-organ pathology during graded bacteremia. Pulmonary artery catheters were placed in 21 adult male pigs under pentobarbital anesthesia and breathing room air. After a control period, animals were studied in four groups: Group 1, anesthesia only; Group 2, infusion of 1 X 10(9) ml Aeromonas hydrophila which was gradually increased from 0.2 ml/kg/hr to 4.0 ml/kg/hr over 4 hours; Group 3, pretreatment with SQ 29,548 (TXA2 antagonist) then Aeromonas h. infusion; Group 4, infusion of U46619 (TXA2 agonist) to pulmonary artery pressures measured in Group 2. Animals were sacrificed after 4 hours and the lungs, liver, spleen, kidneys, and heart were examined under light microscopy by a pathologist unaware of study groups. The results indicated that physiologic thromboxane A2 agonist (Group 4) was sufficient alone to cause pulmonary inflammation. Thromboxane A2 was neither necessary nor sufficient for significant renal, hepatic, pulmonary, or splenic pathology to occur in graded bacteremia, manifested in similar microanatomic abnormalities in these organs in Groups 2 and 3 and in Groups 1 and 4. Pulmonary leukocyte infiltration was significantly increased in Group 3 compared to all other groups, suggesting that TXA2 impairs inflammatory responses.

Abstract
Thromboxane A2 has been implicated as a mediator of cardiorespiratory dysfunction in sepsis. This study evaluated whether or not thromboxane A2 was necessary or sufficient for these adverse effects to occur during bacteremia. Fourteen adult swine under barbiturate anesthesia and breathing room air were monitored with arterial and pulmonary artery catheters. Animals were studied for 4 hours in three groups: group I, graded infusion of 10(9)/ml Aeromonas hydrophila; group II, Aeromonas hydrophila infusion plus SQ 29,548 (thromboxane A2 antagonist); and group III, U46619 (thromboxane A2 agonist) infusion in normal swine to pulmonary artery pressures observed in group I. Hemodynamic parameters, arterial and mixed venous blood gases, and plasma thromboxane B2 and prostaglandin 6-keto-F1 were measured. At sacrifice after 4 hours, wet-to-dry lung weights were calculated. Results indicated that thromboxane A2 was necessary and sufficient for the development of pulmonary hypertension and impaired alveolar-capillary oxygen diffusion in graded bacteremia. It was necessary but not sufficient for increased lung water to occur and sufficient but not necessary for decreased cardiac index and stroke volume index. Thromboxane A2 was neither sufficient nor necessary to the pathophysiology of systemic hypotension during graded bacteremia. Plasma prostaglandin 6-keto-F1 levels were increased in hypotensive animals with sepsis, suggesting its involvement in hypotension during sepsis.

Abstract
Activated complement, thromboxane A2, prostacyclin, and activated granulocytes have been implicated in hemodynamic dysfunction after trauma, in sepsis, and in hypovolemic and septic shock. This study evaluated the interaction of plasma concentrations of complement components C3a and C5a, thromboxane B2 (TxB), prostaglandin 6-keto-F1 alpha (PGI), and granulocyte aggregation in clinical sepsis and hypotension. Forty-eight critically ill patients were followed clinically for as long as 10 days. Plasma C3a, C5a, TxB, and PGI were measured daily by the radioimmunoassay method. Granulocyte aggregation, the percentage of maximum aggregation of zymosan-activated plasma standard curves, was performed with patient plasma and normal human leukocytes. Patients were studied in four groups: group I, nonseptic, normotensive; group II, hypovolemic shock, group III, normotensive severe sepsis; and group IV, septic shock. Plasma from 12 normal adults was the control value. PGI, TxB, C3a, C5a, and granulocyte aggregation in patients were greater than that in the control subjects. Granulocyte aggregation was increased in groups III and IV versus groups I and II. C3a was increased in group IV versus groups II and III. C5a and TxB did not vary between groups. PGI was greatly increased in group IV compared with groups I through III. C3a and C5a decreased in nonsurvivors. PaO2/FiO2 ratios correlated directly with PGI and inversely with C3a and TxB/PGI. Plasma PGI and C3a are increased in septic shock. C3a and TxB/PGI imbalances are involved in hypovolemic and septic shock.

Abstract
This study investigated the interaction of plasma levels of circulating prostaglandins and activated complement in clinical acute respiratory failure (ARDS). Fifty patients at risk for ARDS were followed up for up to ten days. Arterial blood gases and plasma levels of complement components C3a and C5a, thromboxane B2 (TxB), and prostaglandin 6-keto-F1 alpha (PGI) and granulocyte aggregation (GA) were measured daily. Seventeen patients (34%) developed ARDS, with mortality of 41% vs 23% for patients without ARDS. Compared with patients without ARDS, the ARDS group had significantly increased plasma C3a (1,130 +/- 750 vs 636 +/- 368 ng/mL) and granulocyte aggregation (48 +/- 10 vs 17 +/- 4 percentage of the maximum light transmission [% max T]). Plasma C5a, TxB, or PGI did not change significantly with or without ARDS. No measured variable was significantly associated with mortality. Regression analysis revealed significant correlations between GA, TxB, PGI, and arterial oxygenation. Plasma C3a and GA are increased in ARDS, suggesting systemic complement activation. A complex series of interactions between the prostaglandins, complement, and GA appears to be involved in ARDS.

Abstract
Granulocyte aggregation (GA) response has previously been described as a sensitive assay for complement activation in sepsis. Complement component C5a has been implicated as the plasma factor responsible for GA. The quantitative interaction of complement components C3a and C5a with GA, however, is not clearly defined. This study evaluates the relationship of GA responses to plasma levels of C5a and C3a in zymosan-activated plasma (ZAP). The C3a and C5a levels were measured by radioimmunoassay in serial dilutions of ZAP. Granulocyte aggregation responses of normal human leukocytes were determined for each ZAP dilution. The C5a levels in a 1:16 dilution of ZAP were higher than in normal plasma (22 +/- 7 vs 9 +/- 3 ng/mL), as were GA responses (24 +/- 1 vs 11 +/- 2 percentage of maximum light transmission). The C3a levels in a 1:8 dilution of ZAP are elevated above those of normal plasma (656 +/- 167 vs 411 +/- 29 ng/mL). Correlation coefficients were .9809 for C3a vs GA, .9788 for C5a vs G, and .9860 for C3a vs C5a. Complement components C3a and C5a are involved in GA in vitro. Granulocyte aggregometry can detect low levels of activated complement in ZAP but may not be specific for C5a. The relative contribution of C3a and C5a to observed GA is not clear from the data.
