Abstract
Immunohistochemistry of tumour samples is increasingly used in the triage of families where hereditary non-polyposis colorectal cancer (HNPCC) due to mismatch repair defects is suspected. Usually, this is undertaken in tumours that are a recognised part of the spectrum of HNPCC-related cancers e.g. colon or endometrial cancers. Although breast cancers are not classed as part of this spectrum, this study examined the extent to which some breast tumours do arise by the mismatch repair pathway in these families. This may have clinical utility in families where an individual with a 'classic HNPPC-related' tumour is not available for evaluation. Immunohistochemistry of a breast tumour may identify an individual in whom germline mutation testing is worthwhile.

Abstract
Serial blood draws for the assessment of trauma patients' hemoglobin (sHgb) and hematocrit (sHct) is standard practice. A device that would allow for continuous real-time, non-invasive monitoring of hemoglobin and tissue perfusion would potentially improve recognition, monitoring and resuscitation of blood loss. We developed a device utilizing diffuse optical spectroscopy (DOS) technology that simultaneously measures tissue scattering and near-infrared (NIR) absorption to obtain non-invasive measurements of oxy- (Hb-O(2)), deoxyhemoglobin (Hb-R) concentrations and tissue hemoglobin concentration (THC) in an animal model of hypovolemic shock induced by successive blood withdrawals. Intubated New Zealand White rabbits (N = 16) were hemorrhaged via a femoral arterial line every 20 min until a 20% blood loss (10-15 cc kg(-1)) was achieved to attain hypovolemia. A broadband DOS probe placed on the inner thigh was used to measure muscle concentrations of Hb-O(2) and Hb-R, during blood withdrawal. THC and tissue hemoglobin saturation (S(T)O(2)) were calculated from DOS [Hb-O(2)] and [Hb-R]. Broadband DOS-measured values were compared against traditional invasive measurements: systemic sHgb, arterial oxygen saturation (S(a)O(2)) and venous oxygen saturation (S(v)O(2)) drawn from arterial and central venous blood. DOS and traditional invasive measurements versus blood loss were closely correlated (r(2) = 0.96) showing a decline with removal of blood. S(T)O(2) and [Hb-O(2)] followed similar trends with hemorrhage, while [Hb-R] remained relatively constant. These measurements may be limited to some extent by the inability to distinguish between hemoglobin and myoglobin contributions to DOS signals in tissue at this time. Broadband DOS provides a potential platform for reliable non-invasive measurements of tissue oxygenated and deoxygenated hemoglobin and may accurately reflect the degree of systemic hypovolemia and compromised tissue perfusion.

Abstract
BACKGROUND Methods for obtaining real-time in vivo histologic resolution by means of noninvasive endoscopic optical imaging would be a major advance for thoracic surgical diagnostics and treatment. Optical coherence tomography is a rapidly evolving technology based on near-infrared interferometry that might provide these capabilities. The purpose of this study is to investigate the feasibility of real-time 2- and 3-dimensional optical coherence tomographic imaging of airway, pleural, and subpleural lung tissues in normal, inflammatory, and malignant animal models and patients with known or suspected airway malignancy. METHODS Freshly excised lungs and pleural tissue obtained from rabbits with inhalation lung injury and induced empyema, metastatic sarcomas, and pleural sarcomas and from patients with airway disease were imaged by using 2- and 3-dimensional optical coherence tomography with a prototype superluminescent diode optical coherence tomographic system constructed in our laboratory. Lungs and pleural tissue were subsequently processed for standard hematoxylin and eosin histology for comparison with optical coherence tomography. RESULTS Optical coherence tomographic imaging achieved an ex vivo resolution of 10 microm and an in vivo resolution of about 30 microm with a depth penetration of 1 to 2 mm with 2- and 3- dimensional reconstruction capabilities. Tumors as small as 500 microm were detectable with optical coherence tomography. The acquired images closely matched histologic images, demonstrating details at the level of mucosal layers, glands, alveoli, and respiratory bronchioles. CONCLUSIONS Optical coherence tomography with near-infrared interferometric methods enables near real-time in vivo near-histologic resolution optical imaging. With further advances, optical coherence tomography has the potential for real-time accurate and early pleural and subpleural diagnostics by using small-diameter flexible fiberoptic endoscopic probes for a wide range of thoracic surgical applications.

Abstract
OBJECTIVES This study assessed trends in HIV risk behaviors among injection drug users in New York City from 1990 to 1997. METHODS Injection drug users were recruited continuously from a large drug detoxification treatment program (N = 2588) and a research storefront located in a high-drug-use area (N = 2701). Informed consent was obtained, and a trained interviewer administered a structured interview covering sociodemographics, drug use history, HIV risk behavior, and participation in syringe exchange. RESULTS Trends were assessed for 5 risk behaviors in the 6-month period before the interview. The 3 injection risk behaviors declined significantly over time at each site (all P < .01). When data were pooled across sites, all 5 risk behaviors declined significantly over time (all P < .01). Participation in syringe exchange programs and in HIV counseling and testing increased greatly from 1990 to 1997. CONCLUSIONS The continuing risk reduction among injection drug users indicates a "declining phase" in the large HIV epidemic in New York City. HIV prevention programs appear to be making an important contribution to the declining phase.

Abstract
BACKGROUND We aimed to assess audio-computer-assisted self-interviewing (audio-CASI) as a method of reducing under-reporting of HIV risk behaviour among injecting drug users. METHODS Injecting drug users were interviewed at syringe-exchange programmes in four US cities. Potential respondents were randomly selected from participants in the syringe exchanges, with weekly alternate assignment to either traditional face-to-face interviews or audio-CASI. The questionnaire included items on sociodemographic characteristics, drug use, and HIV risk behaviours for 30 days preceding the interview. We calculated odds ratios for the difference in reporting of HIV risk behaviours between interview methods. FINDINGS 757 respondents were interviewed face-to-face, and 724 were interviewed by audio-CASI. More respondents reported HIV risk behaviours and other sensitive behaviours in audio-CASI than in face-to-face interviews (odds ratios for reporting of rented or bought used injection equipment in audio-CASI vs face-to-face interview 2.1 [95% CI 1.4-3.3] p=0.001; for injection with borrowed used injection equipment 1.5 [1.1-2.2] p=0.02; for renting or selling used equipment 2.3 [1.3-4.0] p=0.003). INTERPRETATION Although validation of these self-reported behaviours was not possible, we propose that audio-CASI enables substantially more complete reporting of HIV risk behaviour. More complete reporting might increase understanding of the dynamics of HIV transmission and make the assessment of HIV-prevention efforts easier.

Abstract
Enlargement of the ascending aorta may coexist with concomitant valvular, coronary, or other cardiac diseases. If dilation is moderate (i.e., <6 cm diameter) and another cardiac procedure is being performed, we have reduced the diameter of the ascending aorta with an S-shaped incision and excision of the curves of the "S" as a modified Z-plasty. We have performed the procedure in 23 patients with concomitant procedures including aortic valve replacement in 21 (1 as a pulmonary autograft), coronary bypass in 1, and resection of subaortic stenosis in 1. There were 15 males and 8 females with a mean age of 53 years (range 8-67 years). The mean maximal preoperative diameter on transesophageal echocardiography was 5.0+/-0.7 cm (range 3.2-6.6 cm). The mean intraoperative postreduction diameter was 3.1+/-0.6 cm (range 2.1-4.1) (p<0.01). All patients tolerated their procedures well. Sixteen patients were studied by transthoracic echocardiography postoperatively. These patients had a mean intraoperative postreduction diameter of 2.9+/-0.65 cm that increased to 3.1+/-0.45 cm (p = NS) after a mean follow-up of 9.9+/-12.6 months. Of these, seven patients were studied >1 year postoperatively. Their mean intraoperative postreduction diameter of 2.9+/-0.5 cm increased to 3.1+/-0.35 cm (p = NS) after a mean follow-up of 22.1+/-9.2 months. No known recurrences of the aneurysms have occurred. We feel this technique is valid in patients with moderate aortic dilation undergoing concomitant cardiac procedures and in whom more aggressive aortic interventions are not warranted.

Abstract
Results obtained with intra-aortic balloon pumps (IABPs) at Harbor-UCLA Medical Center from 1990 to 1995 were reviewed to analyze the indications for its use as well as the incidence and types of vascular complications that occurred. Of 86 patients (53 men and 33 women) in whom pumps were used, 66 underwent coronary bypass, 14 underwent valve replacement, and 6 underwent both coronary bypass/valve replacement. Thirteen (15%) deaths occurred (8 coronary bypass patients, 4 valve replacement patients, and 1 coronary bypass/valve replacement patient). The indications for IABP were broadly classified as prophylactic or inability to wean. Prophylactic IABP placement preoperatively occurred in 35 (41%) patients for profound ventricular dysfunction (27 patients), compelling coronary anatomy including critical left main disease (7 patients), and unstable angina (1 patient). Inability to wean occurred in 51 (59%) patients. Three patients (3.5%) developed major vascular complications resulting in limb ischemia. All three underwent thrombectomies, fasciotomies, and above-knee amputations; two patients subsequently died. Vascular reconstruction was performed in two patients as a direct result of their vascular process. All three vascular complications occurred in women. Besides gender, there was no difference between IABP patients with or without vascular complications in terms of age or presence of diabetes, hypertension, smoking history, obesity, or known peripheral vascular disease. These results indicate that IABPs are effective both prophylactically and intraoperatively in patients who would not otherwise survive cardiac surgery.

Abstract
Emergency pneumonectomy for trauma has a high mortality. Although exsanguination is a major factor leading to death, mortality remains high even after adequate resuscitation and is thought to be related to pulmonary edema and right heart failure. We present a series of nine patients who underwent pneumonectomy at Harbor-UCLA from penetrating (7) and blunt (2) trauma. Two patients survived; three initially survived the surgery but died postoperatively of hypoxemia and right heart failure; four died intraoperatively (2 from right heart failure and 2 from exsanguination). One survivor required open cardiac massage for asystole. Careful attention to prevent volume overloading before and during trauma pneumonectomy and maintaining a negative fluid balance postoperatively may contribute to survival in these patients.

Abstract
Although ultrafast computed tomography (UFCT) is able to determine coronary artery bypass graft (CABG) patency, the clinical applicability in the early postoperative period has not been investigated. We prospectively studied 22 consecutive patients who developed angina-like chest pain, electrocardiogram (EKG) abnormalities, elevated creatine phosphokinase-MB fractions (CPK-MB fractions) (> 5%), or sudden cardiac death in the early post-CABG period. UFCT (flow mode) examinations from 4 to 28 days postoperatively were performed at six levels with 13 scans each. Indications for obtaining UFCT included chest pain (14), elevated CPK-MB (14), EKG abnormalities (10), and aborted sudden cardiac death (1). There were 78 grafts evaluated with 87 distal anastomoses. Sixty were saphenous vein grafts (SVG), 16 were left internal mammary artery (LIMA) grafts, 1 was a free right internal mammary artery (RIMA), and 1 was a right gastroepiploic artery. The 60 SVG included 9 sequential grafts with 18 distal anastomoses. UFCT identified 5 occluded nonsequential SVG and of these, 3 underwent coronary angiography confirming the UFCT findings. Visualization was inadequate to determine patency in 5/17 internal mammary artery (IMA) grafts, and all 5 were in the early part of this study and felt to be related to UFCT image protocol. All sequential grafts were determined to be patent on UFCT, although visualization was inadequate to determine if one or both of the outflow distal anastomoses were patent. Our series shows early nonsequential SVG occlusion at 5/51 (9.8%) in patients with postoperative clinical signs of possible graft occlusion. UFCT to determine the patency of proximal grafts is feasible in the early postoperative period. If UFCT is indeed a valid test for graft patency, then this study implies that most signs and symptoms of ischemia in the early postoperative period may not represent graft occlusion.

Abstract
Surgical procedures in the juxtaheptic and intrapericardial inferior vena cava (IVC) are difficult because of the complexity of achieving vascular control in the area. We describe 10 patients with a variety of pathologies in this region who underwent venovenous bypass (VVB) or cardiopulmonary bypass with hypothermic circulatory arrest (CBCA). Renal cell carcinoma with IVC extension was present in three patients (with tumor extension into the right atrium in two), adrenal adenocarcinoma in one, septic IVC thrombus in one, and blunt IVC/hepatic trauma in five. Those patients without atrial involvement underwent VVB with a mean bypass time of 40 minutes (range 12-144). Those patients with tumor extension into the right atrium underwent CBCA with systemic hypothermia to 18(0)C, total body exsanguination for a bloodless field, and removal of the tumor by cavotomy and right atriotomy. The mean bypass, aortic cross-clamp, and circulatory arrest times were 152, 92, and 36 minutes, respectively. Eight of the 10 patients did well and went home within 4 weeks of surgery. Two patients died, one from metabolic sequelae of exsanguinating IVC injury (VVB) and one from sepsis 2 weeks postoperatively (CBCA).

Abstract
BACKGROUND With the advent of screening mammography more breast cancer will be detected at an earlier stage, apparently confined to the breast with no nodal involvement. However, 30% of these will recur due to micrometastases present at the time of diagnosis. Chemotherapy and tamoxifen have been shown to improve disease-free survival in axillary node-negative patients but not overall survival. In the search for a useful predictor of breast cancer recurrence the relationship between c-erbB-2 expression and recurrence and survival was examined. METHODS Eighty-eight axillary node-negative breast cancer patients were followed up for at least 5 years. RESULTS There was a significant relationship between c-erbB-2 expression and both tumour recurrence (P<0.001) and poorer survival (P=0.003). In a Cox multiple regression analysis, c-erbB-2 staining remained the only significant prognostic variable for recurrence (P=0.002) and survival (P=0.032). Tumour recurrence in c-erbB-2-positive cases tended to occur early in the course of follow up and was associated with poorer survival. CONCLUSION C-erbB-2 was found to be a useful prognostic indicator for early recurrence and poorer survival in axillary node-negative breast cancer patients.

Abstract
Peripheric tumours with extension into the inferior vena cava pose difficult management problems. Venovenous bypass using a centrifugal pump to decompress the inferior vena cava may be useful adjunct during vascular isolation of the tumour. We have modified the technique by adding portal decompression to avoid visceral accumulation of toxic metabolites. We have used this technique in two patients who had intracaval extension of tumours, one renal and one adrenal carcinoma.

Abstract
HIV among injecting drug users (IDUs) has now been documented in over 60 countries in the world, and there are an additional 40 countries where injecting drug use has been reported including widespread epidemics in Southeast and southern Asia and in Latin America. At present HIV infection is almost always fatal, and there is no promise that a preventive vaccine will become available soon. Given the enormity of the HIV epidemic among IDUs and the critical need to reduce the spread of HIV transmission to and from IDUs, prevention efforts are essential. Syringe-exchange programs have become a major component of HIV prevention strategies in most developed countries and work within the philosophy of harm reduction. Increasing access to sterile syringes has been met with considerable controversy. Opponents of syringe exchange have generally argued that increasing access to sterile syringes would simultaneously increase the number of injecting drug users, increase the frequency of injection for already active IDUs, and appear to "condone" an illegal behavior. To date many research studies and four major reviews of syringe exchange literature have been conducted. All studies thus far have shown no increase in illicit drug injection associated with syringe exchanges, and significant decrease in drug risk behaviors.

Abstract
The breast tumour distribution of epidermal growth factor receptor (EGFR) was studied in 193 patients with primary breast cancer by immunocytochemistry on frozen sections. EGFR was correlated (P = 0.0009) with growth fraction assessed by Ki-67, and negatively correlated with oestrogen receptor (ER, P = 0.0001) and progesterone receptor (PR, P = 0.0001) status. In 47 patients, in-situ hybridisation for EGFR mRNA showed good agreement with the immunocytochemically assessed EGFR protein. There were, however, several tumours in which EGFR mRNA could be detected in the absence of EGFR protein and there were differences between the ER and PR status of those tumours in which translation of EGFR mRNA was not seen. The cause of these differences is unclear, but these findings may represent a clue as to the differential control of breast cancer cell receptors.

Abstract
Methods of assessing tumor proliferation rates include mitosis counting, flow cytometry and thymidine labelling. While the former is inaccurate and poorly reproducible, the latter methods are time consuming and expensive to perform. Ki-67 is a monoclonal mouse antibody which has been shown to react with a nuclear antigen in proliferating cells. Frozen sections from 75 specimens of breast carcinoma were immunostained with this antibody using an immunoperoxidase technique. The percentage of tumor cells stained, the Ki-67 score, was then compared with a number of pathological and clinical variables in the patients concerned. A positive correlation was seen between the Ki-67 score and mitotic rate (r = 0.71); and a negative correlation was seen between Ki-67 score and estrogen receptor status (r = -0.4). Ki-67 immunostaining may represent a cheap and reproducible method of assessing proliferation rates of breast carcinomas which is applicable in routine laboratories. Further prospective studies are being undertaken to assess its contribution to prognosis.

Abstract
We report 4 cases of ascending aortic dissection in patients with long histories of weight lifting. In 2 of the patients, the initial symptoms of dissection developed while they were lifting weights. Two patients had a history of hypertension and 2 had previously used anabolic steroids. All 4 were successfully treated surgically. Histopathology showed aortic medial changes in all 4. We believe that the hemodynamic stresses of weight lifting, namely, a rapid increase in systemic arterial blood pressure without a decrease in total peripheral vascular resistance, in combination with aortic medial degeneration may have contributed to the development of the aortic dissection.

Abstract
The determination of estrogen receptor (ER) status in primary and metastatic breast tumours has been facilitated by the recent advent of monoclonal antibodies to ER. The aim of this study was to determine the feasibility of estrogen receptor immunocytochemical assay (ER-ICA) applied to cytologic specimens from primary and metastatic breast tumours. One hundred and sixty specimens from 133 patients were evaluated by cytologic ER-ICA. Comparison with histologic ER-ICA was available for 28 of the specimens and with cytosol assay for 27 specimens. Some 101 of the 160 samples were breast lesions of which 87 had a definitive diagnosis of breast carcinoma. Of these, 68% were considered positive for ER. Metastatic breast cancers comprised 59 of the 160 specimens of which 37% were found to be positive for ER. The predominant staining intensity (SI) of the nuclei of the tumour cells added to the percentage of cells (PC) stained gave an estrogen receptor score (ERS) in both cytologic and histologic specimens. A positive threshold was determined for an ERS greater than 2, equivalent to ER levels greater than 10 fmol/mg of protein. We observed very good correlation between cytologic ERS and the corresponding cytosol assay values (r = 0.74; p less than 0.001; n = 27). The sensitivity was 95% and the specificity 88%. Correlation with histologic ER-ICA was also very high (r = 0.83; p less than 0.001; n = 28). We assessed the role of video image analysis (VIA) and did not find any additional advantages in evaluating cytologic ER-ICA.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A report of the species Fusarium proliferatum causing systemic infection in a child with acute lymphoblastic leukemia is presented, with a review of the clinical and laboratory features relating to outcome in disseminated fusarial infections. Thirteen cases of disseminated infection due to Fusarium species have been reported, all but one of which were fatal. Hematologic malignancy is the commonest underlying illness. The frequent occurrence of multiple skin lesions, orbitofacial involvement, and fungemia is in contrast to the otherwise similar disseminated aspergillosis or mucormycosis. Fungemia in disseminated fusariosis may reflect a capacity for invasion of intravascular catheters by Fusarium species. Fusarium isolates from disseminated infections are variably sensitive to amphotericin B, ketoconazole, and miconazole and uniformly resistant to 5-fluorocytosine. The correlation between antifungal susceptibility status and clinical outcome is poor, reflecting problems in susceptibility testing, marginally effective chemotherapy, and serious impairment of host defenses. Attention to early diagnosis and the care of indwelling prosthetic devices may enhance survival until more effective chemotherapy is available.

Abstract
In a prospective 30-month study of nosocomial infections in a pediatric ICU (PICU), the incidence, sites, and causes of infection were determined. Factors associated with increased risk of infection were investigated. In 1,388 patients who remained in the PICU for a minimum of 72 h, 116 infections occurred (6.1 infections/100 admissions). Primary bacteremias comprised 38% of PICU infections and lower respiratory infections comprised 15%. The remaining infections were divided equally among GI, skin, eye, upper respiratory, postoperative wounds, and other sites. Coagulase-negative staphylococci, Pseudomonas aeruginosa, and Staphylococcus aureus were the most prevalent pathogens. Surgical patients had similar rates of infection to medical patients. Patients in the first 2 yr of life, particularly those between 7 and 30 days of age, had the highest rate of infection. Onset of infection was more common after the first week in the PICU with 11% of patients staying 14 to 20 days, 27% of patients staying 21 to 27 days, 48% of patients staying 28 to 34 days, and 52% of patients staying more than 35 days before the onset of infection. The risk of nosocomial infection increases with arterial and central line use, prolonged intubation, ventilation, intracranial pressure monitoring, and paralysis.

Abstract
Frozen tissue sections and cytosols from 89 specimens of breast and ovarian tumours have been assayed for the presence of estrogen receptor (ER) or related protein using four commercially available monoclonal antibody methods. These were estrogen receptor enzyme immunoassay (ER-EIA), estrogen receptor enzyme immunocytochemical assay (ER-ICA), ER D5 antigen immunoradiometric assay and ER D5 antigen immunocytochemical assay. The results have been compared with those obtained using a standard dextran coated charcoal steroid binding assay (ER-DCC). The correlation coefficient (r) between ER-DCC and ER-EIA results was 0.72 while that of both monoclonal antibody cytosol methods and their respective immunocytochemical assays was 0.66. ER-ICA gave additional valuable information concerning receptor heterogeneity in breast cancer sections. However, the correlation between ER D5 antigen assays and both ER-DCC and ER-EIA was weak (r less than 0.4). We conclude that there are a number of methodological advantages in using the kit systems including their ability to detect receptor presence in small tumour specimens (e.g., "Tru-cut" biopsies) but that their usefulness is limited by the current lack of widely available monoclonal based methods for the concurrent determination of progestogen receptor. We believe that, once these are available, immunocytochemical technology could offer an alternative method of determining the steroid receptor concentration in both ovarian and breast tumours, thus obviating the need for costly and time-consuming cytosolic methods, with their inherent difficulties of quality control.

Abstract
The pharmacokinetics of intravenous vancomycin was studied in 20 preterm infants (gestational age, 26.5 weeks +/- 2.6 weeks [standard deviation]; birthweight, 880 +/- 340 g). At the time of the studies their postconceptional age was 36.4 +/- 4.5 weeks. The drug was infused over 30 min in a dose between 9.2 and 18 mg/kg. A highly significant correlation existed between postconceptional age or body weight and vancomycin t1/2 and clearance. Serum creatinine concentrations correlated with vancomycin t1/2 and clearance. Serum creatinine tended to decrease with increasing postconceptional age. Based on the excellent correlation between age (or weight) and vancomycin pharmacokinetics, dose and dose-interval recommendations are presented.

Abstract
Clinical experience with aortic saddle embolus (ASE) is not extensive due to the relative infrequent lodging of emboli at the aortic bifurcation. During the period 1962-1982, 26 patients (mean age, 56 years) were treated at the UCLA Medical Center for ASE and followed from 2 to 158 months (mean, 45 months). These cases were reviewed in order to identify features of diagnosis, anticoagulation, and operation which impact on results. All 26 patients presented with bilateral lower extremity ischemia with or without extension of clot to the iliac bifurcation. Ninety-six per cent of emboli were of cardiac origin and one-third occurred in patients who had previous symptoms of chronic lower extremity ischemia. Rest pain and motor/sensory deficits were main complaints in 92% of the patients, but did not become manifest until more than 6 hours, unlike more distal emboli which have an earlier presentation. Preoperative angiography, even in the patient with a history of claudication, has a small role in planning the surgical approach to patients with ASE and, although performed in 11 patients, it influenced operation in only two. Operation within the "golden period" of 6 hours after embolization did not significantly influence outcome after ASE, since 20 patients were operated on more than 6 hours after embolization, with results similar to six patients who were operated on less than 6 hours after embolization. Early high-dose heparinization, used in all patients and maintained for a mean of 12 days, may have contributed to this effect. In 22 patients (85%) Forgarty catheter extraction via bilateral groin approaches was used with a mortality of 14%; only one death was directly attributed to the catheter embolectomy. In 15% of patients, a direct approach on the aorta was selected with a zero mortality rate. Postoperative functional result was excellent with an amputation rate of only 2% (one limb). Re-embolization occurred in seven patients (27%) after discharge, five of whom had not been maintained on Coumadin and two who were not anticoagulated adequately. The authors conclude that the keys to successful treatment of ASE include high dose heparin which is maintained through the perioperative period, embolectomy without preoperative angiography, and maintenance of long-term oral anticoagulation.

Abstract
Twenty-nine patients with normal blood lipids were placed on diets. Thirteen, mainly attending hospital for varicose veins, were prescribed low-energy diets: HDL-cholesterol was raised after one month and significantly after three months (P less than 0.02); total cholesterol was lowered (P less than 0.05). Sixteen patients, mainly with irritable bowel symptoms, were prescribed high-fibre diet: HDL-C was raised after one month (P less than 0.05), but not significantly so after three months; total cholesterol was unchanged.
