Serum sex hormone levels were measured preoperatively in 57 morbidly obese patients (19 men and 38 premenopausal women) and 12 months after vertical banded gastroplasty. In the male group, there was a significant decrease in estradiol and an increase in follicle-stimulating hormone (FSH), total testosterone and sex-hormone-binding globulin (SHBG). Among female patients, a significant decrease in estradiol, total and free testosterone and an increase in FSH and SHBG was found. Irregular menses present preoperatively in 5 women were corrected after successful weight loss. In conclusion, altered sex hormonal levels and gynecologic abnormalities associated with morbid obesity are corrected with adequate weight loss following vertical banded gastroplasty.

Background. beta-Endorphin is an endogenous opioid involved in the regulation of food intake and obesity as well as in insulin metabolism, In this study, we investigated glucose-induced beta-endorphin, insulin, and glucose responsiveness in morbidly obese patients and the effect of surgically induced weight loss, Methods. Thirty-two healthy, nondiabetic, morbidly obese patients (body mass index over 40 kg/m(2)) and 32 normal-weight controls were studied. Serum levels of P-endorphin, insulin, and glucose were measured under basal conditions and during an oral glucose tolerance test (OGTT) before and 12 months following vertical banded gastroplasty. Results. Preoperative basal levels of beta-endorphin, insulin, and glucose and their responses during OGTT in obese patients were significantly higher compared with those of controls. After surgery, basal beta-endorphin, insulin, and glucose levels decreased significantly compared with preoperative values. Postoperative basal insulin and glucose levels were similar to those in controls, while beta-endorphin levels remained significantly higher than those of controls. A significant reduction in total responses of beta-endorphin, insulin, and glucose during OGTT was also observed; however, postoperative beta-endorphin and insulin responses remained significantly higher than in controls. Conclusion. Morbidly obese patients have an increased glucose-stimulated response of beta-endorphin, insulin, and glucose which is partially corrected with weight loss following vertical banded gastroplasty.

- Abstract
In this report, we studied the immunorestorative properties of subcutaneously administered granulocyte-macrophage colony-stimulating factor (GM-CSF) in patients with refractory solid tumours receiving second-line chemotherapy. Such patients exhibit abnormal immune responses in vivo and in vitro and, therefore, it was of interest to examine the effect of GM-CSF-induced immunomodulation on clinical response. We examined patients with primary malignant carcinomas (head and neck, n = 10; urogenital tract, n = 17; penis n = 6; colorectal, n = 8) who were treated with carboplatin (JM8), 300 ng/m(2) on days 1 and 22, leucovorin (LV), 200 mg/m(2) plus 5-fluoracil (5-FU), 500 mg/m(2) on days 8, 15 and 29 and four cycles of daily injections with placebo or GM-CSF, 300 mu g/day on days 3-6, 10-13, 17-20 and 24-27. Peripheral blood was collected from the patients one day after the end of each of the four-cycle injections with placebo or GM-CSF, namely on days 7, 14, 21 and 28. Peripheral blood mononuclear cells (PBMC) were tested in the autologous mixed lymphocyte reaction (AMLR) and for natural killer (NK) or lymphokine-activated killer (LAK) cell activity. Cytokine levels in serum were measured by immunoenzymatic (ELISA) assay. A total of 21 patients received a four-cycle regimen with GM-CSF (Group 1) and 20 were similarly treated with placebo (Group 2). All received standard chemotherapy as outlined above. Before GM-CSF treatment, all patients exhibited increased serum levels of interleukin-1 (IL-1 beta), tumour necrosis factor-alpha (TNF-alpha), IL-6 and prostaglandin E-2 (PGE(2)) and decreased serum levels of IL-2. Cellular immune responses (AMLR, NK- and LAK-cytotoxicity) were also low in all patients. Five patients from Group 1 had a PR (partial response), 2 patients had CR (complete response), and 14 patients had stable disease. Seven patients from Group 2 showed progressive disease, 3 had a PR and 10 had stable disease. All immune parameters were significantly improved during treatment in Group 1 but remained unchanged or even deteriorated in Group 2. Administration of GM-CSF during treatment of cancer patients with conventional chemotherapeutic drugs results in a marked potentiation of deficient cellular immune responses in vitro and a change towards normalisation of cytokine serum levels. The results reported herein support the use of GM-CSF as immunopotentiator during chemotherapy, but more patients must be studied before definite conclusions can be drawn.

{Objective. This study was undertaken to assess a potential relationship between idiopathic deep venous thrombosis (DVT) and occult cancer. Design. Prospective study with a 2-year follow-up. Setting. The Angiology Unit of the First Department of Surgery, University of Athens, Greece, a tertiary referral centre. Subjects. Two hundred and ninety-three patients with a first episode of venographically or Doppler-proved DVT were included in the study, of whom 264 were followed up for 2 years. \textbackslash{} Interventions. After an initial extensive diagnostic workup, including routine blood counts and chemistries, erythrocyte sedimentation rate, CEA levels, chest X-ray and abdominopelvic CT scan, all patients were closely followed up and periodically examined. Main outcome measures. The incidence of cancer amongst patients with idiopathic and secondary DVT, and the validity of our screening programme. Results. Cancer was diagnosed in 21 out of 84 patients with idiopathic DVT (25\%) as compared with eight out of 202 patients with secondary DVT (4\%). In 22 out of the 29 cases, cancer was detected during the initial admission, and the remaining seven cases were detected during follow-up. Cancer was diagnosed in 15 asymptomatic, healthy individuals, but only in seven of them was the diagnosis made by CT scan. Conclusion. Occult cancer is fairly common in patients with idiopathic DVT, but the routine use of extensive diagnostic studies for its detection remains to be validated by further prospective studies.}

skin and connective tissue diseases - Abstract
The expression of oestrogen receptor (ER) protein in invasive carcinoma of the breast and its clinical significance has been extensively evaluated, Little information is available regarding ER expression in ductal carcinoma in situ (DCIS), In this study, 46 formalin-fixed, paraffin-embedded tissue specimens of mammographically detected DCIS were evaluated immunohistochemically for the presence of ER using specific monoclonal antibodies against ER (ER-ICA Abbott Lab), The associations between ER expression and histological type, degree of differentiation and patient menopausal status were evaluated, Positive ER staining was present in 72% of cases, Non-comedo types of DCIS were more frequently ER-positive than comedocarcinoma, ER-positive tumours were inversely correlated with the presence of nuclear pleomorphism, The incidence of ER in pre-menopausal and post-menopausal women was similar, In conclusion, ER expression is present in a considerable percentage of DCIS, and ER-positivity is associated with the degree of differentiation and non-comedo carcinoma variants.

ABDOMINAL aortic aneurysms , *AORTIC aneurysms , *LIVER cancer , *AORTIC diseases , *ANEURYSMS - Abstract
Background The operative management of abdominal aortic aneurysm (AAA) and co-existing intra-abdominal malignancy has been a long-standing controversy. It is unclear whether a single-stage or a two-stage approach is the more appropriate therapeutic option and also which lesion should be treated first. Case outline An 82-year-old man with a 4×5-cm mass in the left liver (segment IV), suspected to be a hepatocellular carcinoma (HCC), had a concomitant 6-cm infrarenal AAA. At the same operation he underwent a left hepatectomy followed by repair of the aneurysm. He was discharged on the 17th postoperative day. To the best of our knowledge, this is the third report in the world literature of a patient who underwent a successful simultaneous resection of an AAA and HCC and the first in which the liver resection was performed first. Discussion We recommend liver resection and AAA repair in a single-stage procedure, regardless of the time sequence of the procedures. This approach can be considered safe, and the theoretical risk of graft infection can be kept to a minimum. [ABSTRACT FROM AUTHOR]

- Abstract
Objective: The baroreflex sensitivity is impaired in patients with carotid atherosclerosis. The purpose of our study was to assess the impact of carotid plaque echogenicity on the baroreflex function in patients with significant carotid atherosclerosis, who have not undergone carotid surgery., Method: Spontaneous baroreflex sensitivity (sBRS) was estimated in 45 patients with at least a severe carotid stenosis (70%-99%). sBRS calculation was performed noninvasively, with the spontaneous sequence method, based on indirectly estimated central blood pressures from radial recordings. This method failed in three patients due to poor-quality recordings, and eventually 42 patients were evaluated. After carotid duplex examination, carotid plaque echogenicity was graded from 1 to 4 according to Gray-Weale classification and the patients were divided into two groups: the echolucent group (grades 1 and 2) and the echogenic group (grades 3 and 4)., Results: Sixteen patients (38%) and 26 patients (62%) were included in the echolucent and echogenic group, respectively. Diabetes mellitus was observed more frequently among echolucent plaques (χ(2) = 8.0; P < .004), while those plaques were also more commonly symptomatic compared with echogenic atheromas (χ(2) = 8.5; P < .003). Systolic arterial pressure, diastolic arterial pressure, and heart rate were similar in the two groups. Nevertheless, the mean value of baroreflex sensitivity was found to be significantly lower in the echogenic group (2.96 ms/mm Hg) compared with the echolucent one (5.0 ms/mm Hg), (F [1, 42] = 10.1; P < .003)., Conclusions: These findings suggest that echogenic plaques are associated with reduced baroreflex function compared with echolucent ones. Further investigation is warranted to define whether such an sBRS impairment could be responsible for cardiovascular morbidity associated with echogenic plaques., (Copyright © 2011 Society for Vascular Surgery.

- Abstract
Background: This study aimed to evaluate the early post-operative clinical impact of minimal incision aortic surgery (MIAS) for infrarenal abdominal aortic aneurysm (AAA) repair in comparison with the standard open repair., Methods: A case-control study was conducted. Patients of groups A (19 patients) and B (18 patients) were treated with the MIAS technique and the standard open method, respectively., Results: There were significant differences between the two groups in fluid resuscitation during the operation. Post-operatively, there were significant differences between groups A and B in the time until starting liquid diet (2 +/- 0.74 versus 3.55 +/- 0.85 post-operative days (PD), respectively; P < 0.05), the time until starting the solid diet (3.05 +/- 0.77 versus 5.11 +/- 0.75 PD, respectively; P < 0.05), the time of ambulation (2 +/- 0.74 versus 3.4 +/- 0.98 PD, respectively; P < 0.05) and in the hospital length of stay (4 +/- 0.81 versus 9.7 +/- 2.66 days, respectively; P < 0.05)., Conclusions: The MIAS technique, for repair of infrarenal aortic aneurysms, is a safe and feasible procedure that combines the early advantages of endovascular repair with the long-term advantages of the traditional open repair.

- Abstract
We report the use of a unique hybrid technique to treat a patient with a painful aneurysm extending both above and below the inguinal ligament. The patient was at high surgical risk, and endovascular treatment was not possible due to the absence of an appropriate vascular access site. Under local anesthesia, this aneurysm was treated using both a stent graft and a traditional Dacron graft for the iliac and femoral portions, respectively. Simultaneously, a popliteal aneurysm was treated endovascularly through a jump graft, which was used to bypass a short occlusion at the origin of the superficial femoral artery. Hybrid techniques can be an alternative approach in high-risk patients where endovascular procedures cannot be applied.

- Abstract
Infection of aortoiliac endografts is, to date, a rare complication of endovascular surgery. Staphylococcus species are the most common responsible pathogens, just as in cases with infected grafts after open aortic surgery. We report a case of a 65-year-old man with a history of diabetes mellitus and bladder cancer who developed stent-graft infection 3 years after endovascular treatment for a 5.6 cm abdominal aortic aneurysm. The diagnosis of endograft infection was established radiologically by computed tomographic scans. After intravenous administration of antibiotics and fluids to improve his clinical condition, the patient underwent surgical excision of the infected prosthesis and a bifurcated rifampicin-impregnated Dacron graft was placed in situ. Cultures from the purulent fluid around the aorta and from the endograft revealed development of Candida albicans. To our knowledge, this is the first case of an infected endograft due to a fungus. The patient died from septic shock 3 days postoperatively in the intensive care unit.

- Abstract
Introduction: The purpose of this study is to present our experience in the management of patients with abdominal aortic aneurysms (AAA) and aneurysms in both the internal iliac arteries (IIA) at the same time., Methods: Between 2000 and 2005, a series of 13 patients with AAA and also aneurysms in both the IIA, were treated in our clinic. They were all men with a mean age of 74 years. The size of the IIA aneurysms (IIAA) ranged from 2.0 to 8.0 cm (mean, 3.4 cm). All patients underwent an aneurysmatectomy of the AAA and placement of a prosthetic bifurcated aorto-biiliac or -bifemoral bypass, by a transperitoneal approach. The management of one of the two IIAA was the aneurysmatectomy and the direct revascularization of the healthy peripheral portion of the remaining IIA with the ipsilateral leg of the aorto-biiliac bypass. The other IIAA was treated with proximal ligation of its neck and aneurysmorraphy., Results: No patient died during the first 30 postoperative days. Morbidity was about 7.7% (one patient suffered from 'trash foot', which was treated successfully with conservative measures). Finally, the mean stay in hospital was 7 days and no patient clinically presented symptoms of pelvic or colonic ischaemia., Conclusions: Simultaneous treatment of AAA and bilateral IIA aneurysms is a technically difficult, but safe procedure, if it is performed meticulously. Revascularization of at least one internal iliac artery is strongly recommended in order to avoid dangerous complications, such as pelvic or colonic ischaemia.

- Abstract
Background: Extracranial internal carotid artery aneurysms (EICAA) are rare vascular problems with a great potential for lethal thromboembolic episodes., Methods: From 1994 to 2004, nine patients with EICAA, seven men and two women, were surgically treated for 10 aneurysms in our department. Aneurysm led to hemispheric symptoms in six cases (two hemispheric strokes and four hemispheric transient ischaemic attacks). The cause was fibrodysplasia in two cases, atherosclerosis in four cases, trauma in two cases and spontaneous dissection in two cases. All aneurysms were treated surgically by the cervical approach using shunting. Extended cervical approach was necessary in four patients with high-lying aneurysms. Nine aneurysms were totally resected and successful revascularization was carried out. Open aneurysmorrhaphy with vein patch angioplasty was carried out in one case of a saccular aneurysm., Results: There were no perioperative deaths or transient ischaemic attacks or strokes. Four patients developed cranial nerve deficits: one had hoarsness, two had partial facial paralysis (patients with extended cervical approach) and one had tongue deviation. These neurological symptoms were observed in large aneurysms (>4.5 cm) and disappeared within 14 months. No neurological complication was observed in a follow up that ranged from 6 months to 10 years., Conclusions: Surgical repair of EICAA, especially with total resection and arterial reconstruction, is strongly recommended. Extended cervical approach has many technical difficulties but can allow treatment of high-lying aneurysms.

- Abstract
Objective: Abdominal aortic aneurysm (AAA) in patients with end stage renal disease (ESRD) represents a challenging therapeutic problem. This study was undertaken to analyze the surgical outcome of AAA repair in patients with ESRD and discuss the optimal peri-operative management of problems that resulted., Methods: Between January 1995 and January 2005, 11 patients with ESRD underwent abdominal aortic aneurysm repair. All patients were under chronic haemodialysis. Risk factors related to surgical morbidity were evaluated., Results: The average age was 68 years (57-84 years). Nine patients were men: 8 were hypertensive, 6 had diabetes, 4 had coronary artery disease, 3 had suffered a previous stroke, 3 had prior myocardial infarct and 8 were smokers. The duration of haemodialysis was 19 months (range 2 to 46 months). Five of the 11 patients had bilateral common iliac aneurysms in addition to the abdominal aortic aneurysm. The average diameter of infrarenal AAA was 6 cm (4.8-7.5). The mean duration of operation was 191 min. All patients underwent haemodialysis on the day before operation with an average period of 8.5 hours (6-12) and 2 to 20 hours postoperatively. The mean follow-up was 11.5 months (range 1 to 93 months). None of the patients died during the 30-day postoperative period. Two patients died from heart failure 3 and 7 months later., Conclusion: Abdominal aortic aneurysm can be repaired in patients with end stage renal disease with good results, despite the increased morbidity and mortality of this population.

- Abstract
Aim: Carotid body (CB) paragangliomas are rare neoplasms, usually benign. This study deals with our 10-year experience in their surgical treatment and the evaluation of its effectiveness, without preoperative embolization., Methods: During a 10-year period, from 1995 to 2004, we studied the medical records of 11 patients with CB tumors, 8 males and 3 females, whom only one had bilateral tumors. Their age ranged from 23 to 65 years (mean 35 years) and all had a palpable neck mass. Only two of the patients were asymptomatic on admission to our department. Twelve tumors were surgically resected and no patient underwent preoperative selective embolism of his tumor. Two patients had carotid endarterectomies with venous patch angioplasty. No one of the patients underwent radiotherapy or chemotherapy., Results: Perioperative mortality was zero. No stroke or any other cerebral event was observed. One patient, with a grade III tumor, had an injury of the internal carotid artery that was repaired with a vein patch. Three patients had temporal cranial nerve lesions that resolved within 3 months. No malignancy was found even in a 10-year follow-up., Conclusions: Early surgical treatment is strongly recommended in almost all patients. Their resection is a very challenging operation with good postoperative results. Preoperative embolism of the tumor does not need to be a routine procedure. To exclude malignancy, long term follow-up is necessary.

- Abstract
Cancer-related venous gangrene is an extremely rare paraneoplastic syndrome. Here, we present the case of a woman, who suffered from cervical cancer of the uterus and was admitted to our Clinic with venous gangrene in both the right lower and upper limbs. Neither the anticoagulant therapy, nor thrombolysis, succeeded in improving her clinical condition. Cancer is one of the most important causes of venous thromboembolism. Venous gangrene is rarely seen in these patients. Despite adequate therapy, venous gangrene in some very rare occasions may progress to affect further limbs. Mortality in these patients remains very high.

- Abstract
A 27-year-old man was admitted to our hospital for investigation of severe claudication in his right foot. Based on the findings of magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA), we diagnosed anatomic popliteal artery entrapment syndrome, which was causing a short popliteal artery occlusion. Moreover, a long posterior tibial artery occlusion and a peroneal artery lesion had developed as distal thromboembolic complications of the entrapment. Thus, we planned to perform in situ vein bypass graft for the popliteal occlusion and start thrombolytic treatment for the posterior tibial and peroneal lesions. While contemplating the operation, the patient showed a gradual clinical improvement over the next 2 months. A second MRA showed total arterial recanalization of the right posterior tibial and peroneal arteries, although the popliteal artery was still occluded. Spontaneous lower limb arterial recanalization is a rare phenomenon. To our knowledge, this is the first case of spontaneous arterial recanalization after a distal thromboembolic event caused by popliteal entrapment syndrome.

- Abstract
The case of a 25-year-old man admitted with an ulnar artery aneurysm of the wrist is presented. The size of the aneurysm (1.5 x 2.7 cm) and progressive pain gave the impression of a threatened rupture. Radiologic examinations confirmed the existence of a non-thrombosed ulnar artery aneurysm with occlusion of the 4th and 5th digital arteries. During an urgent surgical exploration a pseudo-aneurysm was found and resected and the artery was repaired. Thrombolysis of the digital arteries was performed with a good result. The combination of a large-sized pseudo-aneurysm, lack of a history of penetrating trauma and presentation of threatened rupture are unique and not reported previously in the literature.

- Abstract
Objective: The re-establishment of patency in a stenosed or thrombosed native arteriovenous fistula (AVF) is fundamental to regaining adequate hemodialysis through the same cannulable vein. Many surgeons have been reluctant to use even small segments of synthetic grafts in AVF revisions because of a perception that these would lead to poor results; however, studies comparing various treatment options are scarce. This study compared the use of short (<6 cm) polytetrafluoroethylene (PTFE) segments with pure autologous repair in stenosed or thrombosed native fistulas., Methods: The cumulative postintervention primary patency rates of two groups of hemodialysis patients receiving different surgical revision operations of their vascular accesses were prospectively compared. Group I (n = 30) comprised patients who presented with stenosed or thrombosed native fistulas and received short (2 to 6 cm) interposition PTFE grafts placed after the stenosed or thrombosed outflow vein segment was resected. These short PTFE grafts were not used for cannulation. Group II (n = 29) comprised patients who presented with dysfunctional or failed AVFs and underwent various types of pure autogenous corrections. AVF dysfunction or thrombosis was detected with clinical examination and color duplex ultrasound scanning. In all cases, on-table arteriography-fistulography was performed before surgical repair. Access adequacy was assessed in all patients postoperatively after the first puncture and every month thereafter (mean follow up 16.7 months)., Results: No statistically significant difference in patency was observed between the two groups. Postintervention cumulative patencies were 100%, 88%, and 82% for group I and 90%, 82%, and 71% for group II at 6, 12, and 18 months, respectively ( P = .8)., Conclusions: Short (<6 cm) interposition PTFE segments used for the revision of failing or failed AVFs compare favorably to purely native repair and do not alter the autologous behavior of the initial access. These short PTFE revisions resulted in satisfactory midterm primary patency without further consumption of the venous capital by harvesting segments of vein from other locations and without compromising more proximal access sites. This practice is recommended and is justified as part of an aggressive access salvage policy addressed by many authors so far.

- Abstract
Pseudoaneurysms of the ascending aorta after the original inclusion/wrap technique of the Bentall procedure present a difficult surgical management problem and are associated with substantial morbidity and mortality. Patients with Marfan syndrome frequently develop aneurysms and dissections that involve multiple aortic segments. We present the case of a Marfan patient who successfully underwent repair of a giant ascending aortic pseudoaneurysm and concomitant repair of an abdominal aortic aneurysm. An aggressive surgical strategy followed by life-long cardiovascular monitoring is warranted in order to prolong the survival of these patients.

- Abstract
Celiac artery compression syndrome occurs when the median arcuate ligament of the diaphragm causes extrinsic compression of the celiac trunk. We report a case of a 65-year-old woman who presented with a three-month history of postprandial abdominal pain, nausea and some emesis, without weight loss. There was a bruit in the upper mid-epigastrium and the lateral aortic arteriography revealed a significant stenosis of the celiac artery. At operation, the celiac axis was found to be severely compressed anteriorly by fibers forming the inferior margin of the arcuate ligament of the diaphragm. The ligament was cut and a vein by-pass from the supraceliac aorta to the distal celiac artery was performed. The patient remains well and free of symptoms two and a half years since operation.In this report we discuss the indications and the therapeutic options of this syndrome as well as a review of the literature is being given.

- Abstract
Background: The aim of this study was to investigate the effect of a purified, micronised, flavonoid fraction (Daflon) in lower limb oedema developed after delayed embolectomy and successful reperfusion of acutely ischaemic legs., Methods: Our series consisted of 19 patients with prolonged, acute ischaemia of the lower extremity caused by arterial embolism, who had undergone successful embolectomy. Patients were randomised into two groups; ten patients (group I) treated with flavonoids, were compared to nine given a placebo. Ankle and calf circumferences, venous capacitance and venous emptying time were measured preoperatively [T1], on the 2nd [T2], 5th [T3], 8th [T4] and 30th [T5] postoperative days., Results: An increase of ankle and calf circumference up to 9% and 13.5% respectively, as compared with preoperative values was demonstrated. There was a reduction in oedema formation in patients with the Daflon group, which reached statistical significance only in the ankles (p=0.0276). Calf differences were statistically significant on the second and fifth postoperative days (p<0.05). Venous haemodynamics were considerably improved by Daflon (p<0.001)., Conclusions: Daflon 500 mg had an inhibitory effect on moderate oedema developed after revascularisation of an ischaemic limb.

- Abstract
Background: beta-Endorphin is an endogenous opioid involved in the regulation of food intake and obesity as well as in insulin metabolism. In this study, we investigated glucose-induced beta-endorphin, insulin, and glucose responsiveness in morbidly obese patients and the effect of surgically induced weight loss., Methods: Thirty-two healthy, nondiabetic, morbidly obese patients (body mass index over 40 kg/m2) and 32 normal-weight controls were studied. Serum levels of beta-endorphin, insulin, and glucose were measured under basal conditions and during an oral glucose tolerance test (OGTT) before and 12 months following vertical banded gastroplasty., Results: Preoperative basal levels of beta-endorphin, insulin, and glucose and their responses during OGTT in obese patients were significantly higher compared with those of controls. After surgery, basal beta-endorphin, insulin, and glucose levels decreased significantly compared with preoperative values. Postoperative basal insulin and glucose levels were similar to those in controls, while beta-endorphin levels remained significantly higher than those of controls. A significant reduction in total responses of beta-endorphin, insulin, and glucose during OGTT was also observed; however, postoperative beta-endorphin and insulin responses remained significantly higher than in controls., Conclusion: Morbidly obese patients have an increased glucose-stimulated response of beta-endorphin, insulin, and glucose which is partially corrected with weight loss following vertical banded gastroplasty., (Copyright 1998 Academic Press.)

- Abstract
Background: We prospectively examined the ability of dipyridamole thallium scintigraphy (DTS), as a preoperative screening test, to predict postoperative cardiac complications in patients undergoing peripheral arterial operations., Methods: From November 1993 to November 1995, a DTS study was routinely performed preoperatively in 167 consecutive patients who underwent arterial operations in our hospital. The clinicians were blinded to DTS results. The type of operation was: carotid endarterectomy (n = 53), abdominal aortic aneurysm repair (n = 45), aortobifemoral bypass (n = 31), femoropopliteal bypass (n = 32) and others (n = 6). Clinical and scintigraphic data were collected and analyzed uni- and multivariantly in order to identify those variables that correlate with postoperative cardiac complications., Results: Fifteen adverse cardiac events (three deaths, five myocardial infarctions, seven unstable anginas) occurred postoperatively among 167 patients (mortality: 1.8%, morbidity: 7.2%). Forty-four patients (26.3%) had a normal scintigraphic study, sixty (35.9%) had fixed defects and sixty-three (37.7%) had reversible defects. The most powerful predictive factors of cardiac complications in the multivariate analysis were the synchronous existence of three markers of coronary artery disease (angina pectoris, previous myocardial infarction, Q sign on ECG) and the presence of a reversible defect in the anterior segment of the left ventricle on DTS study., Conclusions: This study demonstrates that the careful and detailed clinical examination is of paramount importance in detecting "high risk" patients and that DTS should be performed as a supplementary test since it offers significant information and further classifies patients of intermediate risk to develop postoperative cardiac complications.

- Abstract
Serum sex hormone levels were measured preoperatively in 57 morbidly obese patients (19 men and 38 premenopausal women) and 12 months after vertical banded gastroplasty. In the male group, there was a significant decrease in estradiol and an increase in follicle-stimulating hormone (FSH), total testosterone and sex-hormone-binding globulin (SHBG). Among female patients, a significant decrease in estradiol, total and free testosterone and an increase in FSH and SHBG was found. Irregular menses present preoperatively in 5 women were corrected after successful weight loss. In conclusion, altered sex hormonal levels and gynecologic abnormalities associated with morbid obesity are corrected with adequate weight loss following vertical banded gastroplasty.

- Abstract
The associations between serum beta-endorphin levels and clinical and metabolic variables as well as beta-endorphin changes after surgically induced weight loss were investigated in 43 morbidly obese patients. A significant positive correlation between beta-endorphin and body weight, degree of body weight increase and ACTH was found preoperatively. Only body weight was independently associated with beta-endorphin levels. Twelve months following vertical banded gastroplasty, there was an extensive weight loss in all patients and improvement in their metabolic profile. A significant reduction in beta-endorphin levels which was proportional to the extent of weight loss was also observed.

- Abstract
In this report, we studied the immunorestorative properties of subcutaneously administered granulocyte-macrophage colony-stimulating factor (GM-CSF) in patients with refractory solid tumours receiving second-line chemotherapy. Such patients exhibit abnormal immune responses in vivo and in vitro and, therefore, it was of interest to examine the effect of GM-CSF-induced immunomodulation on clinical response. We examined patients with primary malignant carcinomas (head and neck, n = 10; urogenital tract, n = 17; penis n = 6; colorectal, n = 8) who were treated with carboplatin (JM8), 300 ng/m2 on days 1 and 22, leucovorin (LV), 200 mg/m2 plus 5-fluoracil (5-FU), 500 mg/m2 on days 8, 15 and 29 and four cycles of daily injections with placebo or GM-CSF, 300 micrograms/day on days 3-6, 10-13, 17-20 and 24-27. Peripheral blood was collected from the patients one day after the end of each of the four-cycle injections with placebo or GM-CSF, namely on days 7, 14, 21 and 28. Peripheral blood mononuclear cells (PBMC) were tested in the autologous mixed lymphocyte reaction (AMLR) and for natural killer (NK) or lymphokine-activated killer (LAK) cell activity. Cytokine levels in serum were measured by immunoenzymatic (ELISA) assay. A total of 21 patients received a four-cycle regimen with GM-CSF (Group 1) and 20 were similarly treated with placebo (Group 2). All received standard chemotherapy as outlined above. Before GM-CSF treatment, all patients exhibited increased serum levels of interleukin-1 (IL-1 beta), tumour necrosis factor-alpha (TNF-alpha), IL-6 and prostaglandin E2 (PGE2) and decreased serum levels of IL-2. Cellular immune responses (AMLR, NK- and LAK-cytotoxicity) were also low in all patients. Five patients from Group 1 had a PR (partial response), 2 patients had CR (complete response), and 14 patients had stable disease. Seven patients from Group 2 showed progressive disease, 3 had a PR and 10 had stable disease. All immune parameters were significantly improved during treatment in Group 1 but remained unchanged or even deteriorated in Group 2. Administration of GM-CSF during treatment of cancer patients with conventional chemotherapeutic drugs results in a marked potentiation of deficient cellular immune responses in vitro and a change towards normalisation of cytokine serum levels. The results reported herein support the use of GM-CSF as immunopotentiator during chemotherapy, but more patients must be studied before definite conclusions can be drawn.

- Abstract
Incidentally discovered adrenal masses are common since the advent and application of sensitive noninvasive imaging methods. The significance of these so-called "incidentalomas" and the question of further evaluation or treatment remains elusive. This report describes a retrospective study of 86 patients with incidentaloma. Adrenalectomy was performed on 26 patients during initial admission. Histologically, two cortisol-producing adenomas, an adenoma with subclinical cortisol production, and two pheochromocytomas (all of the preceding detected during the preoperative hormonal evaluation), three cystic lesions, one myelolipoma, and one hematoma were found. One primary and two metastatic adrenal carcinomas were also found in this series. Sixty patients with a nonfunctioning incidentaloma smaller than 6 cm were observed in an average of 43 months with serial CT scans performed at 3, 9, and 18 months after the initial diagnosis. Enlargement of the mass was detected in two patients; both proved to be nonfunctioning adenomas. Based on these observations, it is concluded that the initial laboratory evaluation is mandatory in cases of incidentalomas, including parameters of adrenocortical and medullar function. Hormonally active incidentalomas and those suspected for malignancy should be treated surgically. Masses greater than 6 cm should also be removed. Smaller incidentalomas without endocrine activity or signs of malignancy should be followed by CT scan at 3, 9, and 18 months after the initial diagnosis.

- Abstract
The expression of oestrogen receptor (ER) protein in invasive carcinoma of the breast and its clinical significance has been extensively evaluated. Little information is available regarding ER expression in ductal carcinoma in situ (DCIS). In this study, 46 formalin-fixed, paraffin-embedded tissue specimens of mammographically detected DCIS were evaluated immunohistochemically for the presence of ER using specific monoclonal antibodies against ER (ER-ICA Abbott Lab). The associations between ER expression and histological type, degree of differentiation and patient menopausal status were evaluated. Positive ER staining was present in 72% of cases. Non-comedo types of DCIS were more frequently ER-positive than comedocarcinoma. ER-positive tumours were inversely correlated with the presence of nuclear pleomorphism. The incidence of ER in pre-menopausal and post-menopausal women was similar. In conclusion, ER expression is present in a considerable percentage of DCIS, and ER-positivity is associated with the degree of differentiation and non-comedo carcinoma variants.

- Abstract
One of the most serious complications in vascular surgery is infection of the vascular arterial prosthesis (VAP) which might lead to loss of limb or even death. Very often infected prostheses are combined with infectious infiltration of the adjacent tissues or even necrosis and their loss. This paper deals with the experience in the management of 5 patients suffering from infection of vascular arterial prostheses in various locations, for by-passing abdominal aorta and distal arteries with loss or necrosis of the skin and tissues adjacent to the graft. Removal of the infected graft was performed in all of the cases, together with wide debridement of the infested area and placement of a new graft, coursing far from the infected area for revascularization of the affected limb. The cleaned infected area was covered at a first or second stage by applying plastic procedures utilizing musculocutaneous tissue transfer. The results were quite satisfactory. We conclude that the management of infected vascular arterial prostheses, when these are combined with loss of adjacent tissues, is a challenge for the Vascular Surgeon. Their removal, extended cleaning and covering of the area by means of plastic procedures with tissue transfer, proved to be effective in the management of this problem.

Objective: This study was undertaken to assess a potential relationship between idiopathic deep venous thrombosis (DVT) and occult cancer., Design: Prospective study with a 2-year follow-up., Setting: The Angiology Unit of the First Department of Surgery, University of Athens, Greece, a tertiary referral centre., Subjects: Two hundred and ninety-three patients with a first episode of venographically or Doppler-proved DVT were included in the study, of whom 264 were followed up for 2 years., Interventions: After an initial extensive diagnostic workup, including routine blood counts and chemistries, erythrocyte sedimentation rate, CEA levels, chest X-ray and abdominopelvic CT scan, all patients were closely followed up and periodically examined., Main Outcome Measures: The incidence of cancer amongst patients with idiopathic and secondary DVT, and the validity of our screening programme., Results: Cancer was diagnosed in 21 out of 84 patients with idiopathic DVT (25%) as compared with eight out of 202 patients with secondary DVT (4%). In 22 out of the 29 cases, cancer was detected during the initial admission, and the remaining seven cases were detected during follow-up. Cancer was diagnosed in 15 asymptomatic, healthy individuals, but only in seven of them was the diagnosis made by CT scan., Conclusion: Occult cancer is fairly common in patients with idiopathic DVT, but the routine use of extensive diagnostic studies for its detection remains to be validated by further prospective studies.

- Abstract
The epidemiological characteristics of 359 difficult intubations resulted from retrospectively collected data in a series of 4.742 individual anaesthetic case records of consecutive adult patients (2392 men, 2350 women) undergoing general anaesthesia for routine surgery. The preoperative assessment of each patient's airway was performed using standardized guidelines. Mandibular length, body weight and mobility of jaw, head and neck were evaluated with simple measurements. The presence of protruding maxilla or upper teeth, tongue tumor or cyst, long narrow mouth, short muscular neck and deviation of larynx or trachea was based on clinical and/or radiological examination. Severity of difficulty in intubation was estimated on a five-point scale grades (0-4) according to the view obtained at laryngoscopy and the final outcome of airway management. Difficult intubation (grades 1-4) was confirmed in 359 cases (7.6%) of which 208 were anticipated (57.2%). The effectiveness of preoperative evaluation had a positive correlation with the level of difficulty since, the greater the grade of difficulty the greater the sensitivity. The prevalence of failed intubation (grade 4) was 0.5%. Risk factors which had been correlated with the relative size of the tongue proved to have low probability and level of difficulty of intubation. The most important risk factor was limited jaw movement (median grade of difficulty: 4, positive predictive value: 75.0%). Large endemic goitre and thalassaemia constitute RFs contributing occasionally to difficult airway. The positive predictive value was 61.5% and 40.9% respectively. The combination of risk-factors had a cumulative impact contributing to the high level of difficulty.
