Safety and efficacy of autologous hematopoietic stem-cell transplantation following natalizumab discontinuation in aggressive multiple sclerosis.

BACKGROUND AND PURPOSE: Natalizumab (NTZ) is a highly effective treatment for relapsing-remitting multiple sclerosis (MS), but its withdrawal is often followed by disease reactivation or rebound, even if other disease-modifying treatments (DMTs) are administered. In this study, for the first time, the safety and efficacy of autologous hematopoietic stem-cell transplantation (aHSCT) performed following NTZ discontinuation were retrospectively compared with conventional DMTs. METHODS: Patients with relapsing-remitting MS treated with NTZ who discontinued the drug after at least six administrations and with at least 6 months of follow-up were included. Patients underwent aHSCT after a minimum of 6 months following NTZ withdrawal, receiving meanwhile cyclophosphamide or corticosteroids, or other DMTs approved for MS (control group) after an adequate wash-out period. Both hematological and neurological follow-up were assessed according to standard policies. RESULTS: A total of 52 patients were included, 11 who received aHSCT and 41 who received DMTs. Baseline clinical and demographic characteristics were similar between the two groups. No fatality or life-threatening complications, including progressive multifocal leukoencephalopathy, were observed. At 3 years following NTZ discontinuation, no evidence of disease activity was reported in 54.5% of the patients in the aHSCT group compared with 11.5% of those in the DMT group (P = 0.0212). Disease reactivation in the patients with aHSCT was observed only during wash-out/bridging therapy and 100% of the cases were free from disease activity after aHSCT. CONCLUSIONS: These data suggest that an aggressive therapy should be established after NTZ with the shortest possible wash-out period. aHSCT after 6 months from NTZ withdrawal appears to be safe.

Palliative surgery for gastric cancer in elderly patients.

Poor survival rate of elderly patients affected by locally advanced or metastatic gastric cancer is related to primary tumour complications. Bleeding is the most important adverse event, other major complications are gastric outlet obstruction and nutritional deprivation. Rarely the patients will perforate the stomach cancer and there is a sudden end to their life; contamination of the ascites result in a rapid death. Thus, an aggressive approach toward palliation of this condition is resection: in this manner the expected survival is approximately one year. Derivation techniques or endoscopic treatments are applied in those patients whose operative risk is inacceptable; in these cases poor median survival is expected. The aim of this report in to refer about the experience in palliative surgery for gastric cancer in the Department of Geriatric Surgery of the University of Padua.

[Ischemic pathogenesis of acute pancreatitis. A case report]. / La patogenesi ischemica della pancreatite acuta. Una osservazione clinica.

An ischemic origin of acute pancreatitis has been considered for a long time, at least as an aiding factor: ischemia has a fundamental role in the development of necrotizing pancreatitis from an oedematous one. Shock, heart condition and celiac-mesenteric ischemia can determine the onset of an acute pancreatitis through local ischemic lesions. Personal experience with a case of acute pancreatitis following an intestinal ischemic failure is reported. The duration of ischemia and, in particular, the free radicals formation during the organ reperfusion have been considered as the main pathogenetic factors. In the observed case, the ischemic hypothesis seems to be supported from the lack of other known factors and from the intestinal ischemic failure episode.

Influence of age and menopausal status on pathologic and biologic features of breast cancer.

The distribution of the main prognostic factors in different age groups was evaluated in 1226 patients operated on for primary breast cancer, in order to identify those influenced by age and/or menopausal status. Patients were divided into the following groups: 1) 40 years of age and under; 2) premenopausal over 40 years of age; 3) postmenopausal under 75 years of age and 4) 75 years of age and over. Our findings showed that the youngest patients had the worst prognostic pattern, which improves as age increases and is the best in patients over 75 years of age. Some of the parameters investigated (tumour size, histologic and nuclear grade, tumour infiltrating lymphocytes, p53 and Ki 67) were found to be influenced by age, some (necrosis and oestrogen receptors) were influenced by menopausal status and/or age, some (vascular invasion, ploidy, S-phase and progesterone receptors) showed significant differences in different age groups but there was no consistent relation with patient age or menopausal status, and others (node status, ErbB2/Neu and Cathepsin D) were not influenced by age or menopause.

[Hürthle cell carcinoma and "insular" carcinoma: uncommon varieties of thyroid carcinoma]. / Carcinoma a cellule di Hürthle e carcinoma "insulare", varietà non comuni del carcinoma tiroideo.

The Hürthle cell carcinoma and "insular" carcinoma are two uncommon types of thyroid carcinoma. These neoplasms do not present accurate characteristics as to incidence, natural history, pathophysiology and therapies. Two cases are presented: the first was submitted to near-total thyroidectomy for Hürthle cell carcinoma, the second to total thyroidectomy for "insular" carcinoma with bone and lung metastases. Some literature previous studies on pathophysiology and natural history of both tumors are discussed. At the end, personal trend on the surgical treatment of these two thyroid neoplasms is presented: total thyroidectomy for CCh and "insular" carcinoma, and near-total thyroidectomy for Hürthle cell adenoma.

[Colo-uterine fistula, a complication of sigma diverticulitis]. / Fistola colo-uterina, complicanza della diverticolite del sigma.

The colo-uterine fistula is a rare complication of diverticular disease of the colon; the literature review has shown only few well studied cases. The fistula, among the complications of the sigma diverticulitis, is 20% of the observed cases; generally, the bladder is the most involved organ, but also the skin or gut can be interested. If we consider the aetiology of the colo=uterine fistula of the observed case, the presence of the sigma locked stenosis with an endocolic pressure increase, associated with a peridiverticulitis condition, seems to have a relevant rule. The clinical symptomatology is represented by vague abdominal pain localized in particular in the left iliac cavity and by emission of blood, purulent material and stools from the vagina. The diagnosis of colo-uterine fistula is not easily reached: barium enema, Fallopian tube endoscopy and colon endoscopy not always allow to visualize in a right manner the fistula and only the oral administration of non-absorbable substances to be searched in the vaginal tampon, clear each doubt. Regarding the therapy to be carried out, we think that, colic resection en bloc with the uterus is the treatment of choice, while, in emergency, the Hartman operation is the most suitable to avoid the beginning of septic complications.

[The involvement of the urinary tract in inguinal hernias]. / L'impegno dell'apparato urinario nelle ernie inguinali.

The involvement of the organs of the urinary tract in an inguinal hernia represent a constant trap for the surgeon because the diagnosis of that pathology is very rare. The authors report two cases: 1) male, carrier of a voluminous bilateral inguinal hernia, that on the right, contains a diverticulum of the bladder. 2) male, with a bilateral inguinoscrotal hernia. Bilaterally the hernia contains the ureter. The hernias of the bladder properly called are very rare but the involvement of a small portion of the organ, often a diverticulum, in an inguinal hernia is more frequent and always associated with hypertrophy of the prostate. The relative symptoms to this interest seem to supply obvious indications but very rarely are interpreted in the right way. The hernias of ureter are rare too, some acquired, some, about a quarter, congenital. The case-history don't supply useful news for the diagnosis. In the most of the cases of involvement of the urinary tract organs in an inguinal hernia, we arrived at operative-room without knowing the hernia content. The structures of urinary tract usually are recognised by particular maneuvers but is not infrequent that, moreover unforeseen, they are accidentally damaged.

[Physiopathology of intestinal anastomoses and dehiscences]. / Fisiopatologia delle anastomosi intestinali e delle deiscenze.

A lot of mechanisms of healing of intestinal anastomoses has been explained. A leading role in the intestinal wall is made by the submucosal tunica, where collagen synthesis and degradation process take place, but local and systemic factors are present by a definite causal action. Technique of suture, materials and surgeon's experience are of fundamental importance for the success of operation, even if in some cases it is important to take in consideration the clinical situation: emergency or not, the patient's state and age, concomitant diseases, pharmacological or radiotherapeutic treatments. Nowadays surgical research tends towards biochemical and molecular field to identify the factors, that speed up the healing process to use them in suturing materials getting a quick healing as soon as possible.

[Breast cancer in elderly women]. / Il carcinoma della mammella nell'anziana.

Breast cancer represents an important epidemiological and clinical problem, and the elderly age represents a large proportion of women with breast cancer. In patients older than 65-year, the frequency of breast cancer is 50% and more. Early diagnosis and adequate therapy may play an important role also in the elderly. We performed a retrospective analysis of 146 women older than 65-year to determine the effect of age in management of the disease.

[Complications of peptic ulcer disease in the elderly]. / Le complicanze della malattia peptica nell'anziano.

Peptic disease is even more described in the elderly patients. Is it different from the young people peptic disease? Is it a specific syndrome? These questions are debated by the authors from their experience about in the old age surgery. In 1997, out of 569 oesophago-gastro-duodenoscopies positive for peptic disease, about 2/5 of the patients were older than 65-year with a high percentage of hypersecretive patients. Also the incidence of complications is similar in the aged and young patients, but their course is much more serious in the elderly. NSAID therapy was not always demonstrated as a determining factor of complications in the elderly. The ulcer perforation is the most serious complication; in the over-70 year aged persons a very severe course is often demonstrated. In conclusion in the elderly a specific diagnostic and therapeutic care is recommended to avoid the high incidence of deadly complications.

[Stomach cancer in the elderly]. / Il cancro gastrico nell'anziano.

Gastric cancer often affect very old patients even if it is not a typical disease of the elderly. The Authors report their experience on 108 patients (mean age of 77.8 years) affected by gastric cancer; early diagnosis and surgical technique are discussed.

[Surgery of inguinal and femoral hernia in the elderly]. / La chirurgia dell'ernia inguinale e crurale nell'anziano.

Old people are continuously increasing in frequency but age is not a significant factor to value the operative risk in hernia surgery. From June 1985 to December 1996, 189 patients, aged > 80-year, were submitted to hernia surgery. No complications were noted when elective surgery was performed. Emergent procedure was undertaken in 7% of the patients major perioperative complications and one death were registered in this group of patients. Mean hospital stay has decreased in the period of the study: was 2.2 days in the last two years. Local anesthesia permitted a day surgery procedure in 60% of cases.

[Personal experience in the area of colorectal anastomoses without protective colostomy]. / Esperienza personale nel campo delle anastomosi colo-rettali senza colostomia di protezione.

The Authors report their past 3-year-experience in colorectal anastomosis without protective colostomy. General results in terms of complications and mortality rates are similar if not even better than those referred by the international Literature.

Perforations of the extraperitoneal rectum during barium enema.

Rectal injuries during barium enema are uncommon but not unusual complications. Radiologists and surgeons must be able to recognize them, as early diagnosis is essential for effective treatment. The Authors discuss various aspects of problems arising from rectal perforation, and report their experience on seven cases.

Sleeve lobectomy in the treatment of bronchogenic carcinoma.

From 1980 to 1985, 44 sleeve lobectomies were carried out in patients with bronchial cancer. Sixteen patients received preoperative radiotherapy. Perioperative mortality was 6.8%. There were seven anastomotic complications (three fistulae and four stenoses) and two recurrences at the anastomosis. Overall actuarial survival was 45% at four years. These results seem to suggest that sleeve lobectomy should be considered an elective rather than a compromise procedure and a viable alternative to pneumonectomy. Preoperative radiotherapy neither increases complications nor has a negative effect on outcome. It contributes towards reducing local recurrences and maximizes tissue salvage. Long-term survival is related to stage or histology, factors generally governing the survival of lung cancer operated patients, although the TNM classification is ill-suited to identifying tumors which can be resected by a sleeve lobectomy.
