Analysis of survival in a sample of elderly patients from Ragusa, Italy on the basis of a primary care level multidimensional evaluation.

The detection of frail elderly people is a crucial point in planning health care services. The aim of this study is to assess the effectiveness of a multidimensional evaluation instrument in order to identify frail elderly people, in a primary care setting. In 1994, a 15-20-min multidimensional questionnaire, called Geriatric Functional Evaluation (GFE), was administered to 3060 over 65-year-old citizens of Ragusa (Italy), who live in their own home. The sample was subdivided in three groups (independent, moderately impaired, and severely impaired) on the basis of the Final Synthetic Score (FSS) originated by the answers to the questionnaire. A follow up was carried out in 1999 with survival and institutionalization as the end-point. The lost to follow-up rate was 1.2%. After 5 years, the Kaplan-Meyer survival analysis showed that the survival rate of the three groups was 42%, 68%, and 88%, respectively. The Cox Proportional Survival analysis showed that the risk of death was doubled in the moderately impaired group and tripled in the severely impaired group compared with higher FSS group. The multivariate analysis showed that the use of services was increased by 40% and therefore indirectly their need, shifting from the lowest to the highest score. The FGE questionnaire had a strong predictivity of both mortality and need of services. The use of FGE in a primary care setting could make it possible to detect the frail population in order to address the community based services.

[Effects of octreotide (somatostatin analog SMS 201-995) on superior mesenteric artery blood flow in swine. An experimental study using Doppler color ultrasonography].

The effect of octreotide on splanchnic haemodynamics was investigated in 25 domestic pigs by mean of US-colordoppler. In a blind-operator design the superior mesenteric artery (SMA) blood flow was evaluated before and after i.m. injection of 5, 10, 20, 25 micrograms/kg or of an equivalent volume of saline solution. Seven serial measurements were taken every 10 min in each pig excluding the higher and the lower values. The administration of 5 and 10 micrograms/kg determined a rapid and stable (3 hours) decrease of the SMA blood flow (6 and 8.5% respectively) (p < 0.05). The blood flow decreased by 27-29% (p < 0.001) in response to the administration of 20 and 25 micrograms/kg respectively. The reduction started 30 min after injection and the blood flow remained lower than basal for up to 5 hours. Because of the mean standard error of US blood flow assessment is 10% due to the interobserver and intraobserver variations, we considered statistically significant only the reduction occurred after the administration of 20 or 25 micrograms/kg. Authors findings suggest that high dose of octreotide is effective in reducing the splanchnic haemodynamics in the pig. Such animal can be used in experimental setting planed to assess the effect of splanchnic blood flow reduction.

[Recurrent liver metastases from colorectal cancer: their surgical treatment].

Records of 8 patients undergoing repeated operation for isolated hepatic metastasis were reviewed for operative morbidity and mortality, survival, disease-free survival. The mean interval between the initial colon operation and first hepatic resection and that between the first and the second hepatic operation were calculated. Both were found to be correlated with survival of these patients. Repeat hepatic operation for recurrent colorectal metastasis to the liver yields comparable results to first hepatic resections in terms of operative mortality and morbidity, survival, disease-free survival. Repeated hepatic operation is the most successful for of treatment for isolated recurrent colorectal metastasis.

[The so-called postcholecystectomy syndrome after laparoscopic intervention].

Preoperative symptoms have been found to persist in up to 30% of patients after open cholecystectomy. No data exists about the influence of laparoscopic cholecystectomy on symptoms. A group of 109 elective patients who had undergone at least 12 months previously laparoscopic cholecystectomy were retrospectively studied. Pre- and postoperative symptoms were compared and patients satisfaction graded from 1 (excellent) to 5 (worst). More than two symptoms were present preoperatively in all patients. Postoperatively 75 patients were absolutely symptomless. 9 patients complained of only one symptom, and 25 patients continued to have two or more symptoms. The mean time to return to full activity did not correlate with the number of postoperative symptoms. Most patients (75) considered the procedure completely successful while only 6 were no better off postoperatively. The incidence of symptoms after laparoscopic and laparotomic cholecystectomy is similar. The patients should be advised that the presence of preoperative symptoms are not necessarily caused by gallstones and that cholecystectomy might be followed by the persistence of symptoms.

[Giant lipoma of the thigh: report of a case].

The clinical findings and surgical management of a 58 years old woman with a large lipoma of the thigh are reported. Giant lipomas of the thigh, infrequently observed, are of interest because causing functional limitation and lymphedema, due to their tendency to recur after surgical removal and their potential hazard of malignant transformation. Specific diagnostic tools are discussed. Surgical excision is the first-choice treatment of a giant lipoma of the thigh.

[Functional results of experimental autologous transplantation of the pancreas].

The autotransplant of the left lobe of the pancreas in the latero-cervical region has been successfully performed in 38 adult beagles with a mean cold ischemia time of 52 minutes. Juice volume and amylase, protein and bicarbonate outputs were resumed postoperatively as soon as 6 hours. A single case of thrombosis of the mesenteric vein occurred; all other pancreatic grafts showed good histological vitality at 30 days. This procedure of autografting is proposed as a valid experimental model for the pathophysiologic study of acute pancreatitis.

[Laparoscopic treatment of gastroesophageal reflux].

Gastroesophageal reflux disease (GERD) is a frequent illness, sometimes causing disabling symptoms and/or permanent oesophageal lesions. Etiology is multifactorial and not completely defined. Therapy is medical at first step, surgical indication is reserved to those patients with less compliance for medical therapy, unsuccessful medical therapy or reflux related complications. Different surgical techniques have been suggested for treatment of GERD, like Nissen, Rossetti or Toupet fundoplication. During the last decade laparoscopy has been proposed as a less invasive approach when surgery is indicated. From 1995 to the first months of 1999, 42 pts (28 females, 14 males, mean age 53.7 years), were operated on. Diagnosis and surgical indication were confirmed preoperatively by barium X-rays, endoscopy and 24 hrs-Ph-manometry. Hiatal hernia was demonstrated in 37 cases (88%), I or II grade esophagitis in 16 and III grade in 2; 1 patient had Barrett oesophagus. 37 pts were operated on by laparoscopic Nissen fundoplication, 5 patients had a Toupet operation. Mortality and conversion rate were 0. Complications occurred in 3 patients: 1 intraoperative pneumothorax, 1 acute cardiac ischemia in a patient with known hypertension, 1 permanent dysphagia successfully treated by endoscopic dilatation. Mean postoperative hospital stay was 6.1 days. Mean follow up was 9 months (3-48) in 100% of cases. Despite the fact that few patients were operated on by using this new less invasive approach, results are encouraging with no mortality, less morbidity and great advantages for patients.

[Cholelithiasis in men. Observations on a case series of surgically treated 3,047 patients].

Age and clinical presentation as acute cholecystitis have widely been found to be predictors of outcome after cholecystectomy. Recently, male gender has been cited in several studies as a possible prognostic factor. A single Institution cholecystectomy registry (3.047 cases between 1959-1997) comprising 966 (31.7%) men and 2.81 (68.3%) women was retrospectively analysed. Men experienced significantly higher rate of major complications (5.3% vs 3.2%; p < 0.01) and mortality (1.55% vs 0.62%; p < 0.03). By logistic regression analysis, it was found that male gender, acute cholecystitis, respiratory and cardiovascular system disease were significantly related to postoperative morbidity. Age older than 65 years, male gender, respiratory and cardiovascular diseases were factors negatively affecting operative mortality.

[Layered and mass sutures in the closure of median laparotomies].

A retrospective comparison of 2830 patients with midline abdominal incision closures was made. Dehiscences, infections, hernias were compared examining continuous mass closures (group A) versus interrupted mass closures (group B) and interrupted layered sutures (group C). The three groups were well matched for known risk factors for each of the above complications. Mass closures produced a significant higher number of infections (p = 0.0006) and hernias (p = 0.0001). There was no significant difference in the rate of dehiscences in the three suture groups (p = 0.07). A significant correlation was found in all three groups between the incidence of infections and that of outcoming incisional hernias. In the current study layered closure of the of the midline abdominal wounds yielded better results when compared with both running mass and interrupted mass closures. The knowledge of these findings might help when choosing the procedure to close a midline abdominal incision.

[Ambulatory closed surgery for the treatment of pilonidal sinus].

Pilonidal disease (PD) is a common chronic disorder of the sacrococcygeal region afflecting young people. Despite several methods for treating PD have been described, the management remains controversial. Recent reports have advocated different surgical approaches such as open or closed technique, but recurrence plagues all forms of therapy. We conducted this case review to evaluate the validity of an outpatient closed technique in the treatment of chronic pilonidal disease. Between January 1997 and July 1999, 65 consecutive patients with quiescent chronic PD were electively treated by surgical excision of the cyst and primary closure. There were 47 men (72%) and 18 women (28%) in this study. Patients ranged in age from 14 to 47 years, the average age being 21 years. The median healing time was 8 days and the median time to return to full work was 20 days (range 10-25). Infection and recurrence rates were 1.5% and 4.6% respectively. There was no correlation among recurrence rate, postoperative infection, or prior surgery. Cyst excision and primary closure is a safe, low cost operation with a very high long-term success rate and a negligible rate of complications. It can successfully be performed under local anaesthesia in an outpatient facility.

[Social and health services needs in a sample of elderly people in Catanzaro].

The aim of this study is to analyze the general health state conditions of older people living in Catanzaro, using a multidimensional assessment instrument to determine their social and health needs. To this purpose, a sample of 544 individuals (344 women and 210 men) older than 65 years of age (mean age = 75.3) was selected from the general population. All subjects were administered the OARS (Older Americans Resources and Services) questionnaire that evaluates five areas: physical health, mental health, social resources, economic resources and Activities of Daily Living (ADL). The percentage of subjects with score 3 or more in each area, and therefore identified as partially or totally dependent, is higher in the area of physical health (17.9%) and ADL (16.6%). About 65% of the sample is not disabled in any of the different areas, while 8% is dependent in 3 or more areas. These subjects are partially or totally dependent elderly people, who stay at their own house in precarious conditions, and are able to remain there only because they are helped by informal caregivers. Probably these people are those for whom any domiciliary help is necessary and more urgent in order to support the existing stability and to avoid institutionalization.

[Carcinoma of the male breast. Prognostic factors and outcome of surgical treatment].

A retrospective study was made on 18 male patients with breast carcinoma treated at the Department of Surgery "Pietro Valdoni" of the University "La Sapienza" of Rome, Medical School. Demographics, pathology, stages, and treatment were determined from clinical reports. All patients but one underwent modified radical mastectomy. The length of follow up averaged 57.5 months. Five years actuarial survival rate was 62%. In the current study the Authors suggest that the clinical, prognostic and treatment features of breast carcinoma in men are similar to those reported in literature for post-menopausal women.

[Multidimensional functional evaluation of social and health care needs of an elderly population in Rome].

The aim of this study is to analyse the condition of the elderly of Rome through a multidimensional instrument to determine their assistance needs. To this purpose a sample composed by 693 over 65 subjects was selected (430 women and 263 men). The Geriatric Functional Rating Scale of Grauer was administered to them. The questionnaire is divided into 7 sections (physical health, mental health, functional skills, support to the collectivity, type of housing, social relationships and economic situation); they enable to evaluate the dependency level of each subject. On the base of each area score a total score is obtained which divides the elderly into three categories according to their assistance need. The whole information collected in the single areas led to a definition of non self-sufficiency for 4.9% of the interviewed people and of partial self-sufficiency for 5.3%, the rest of the sample turned out composed by subjects able to live in an autonomous way. This sample of elderly (about 10%) is that on which it is possible to intervene with social and/or health home care plans in order to limit institutionalization.

[Hospital expenditure for the elderly in Italy].

The consequences of demographic and epidemiological transition have deeply involved the health care systems of western countries. Both the highest burden of care and the higher costs of in-patient services are due to the elderly patients. The aim of this paper is to evaluate the percentage of in-patient care due to the elderly patients and the role played by this care on affecting costs. To this purpose all the Italian 1996 discharge reports referred to in-patient care longer than one day, have been analysed. About 40% of in-patient care expenditure is due to over-65 patients while the percentage of the elderly of total Italian population is roughly 17%. The highest age-specific hospitalisation rate are due to cardiovascular and neurological diseases. Only 4 out of 30 most frequent DRGs among elderly patients are surgical pathologies, while the others are medical ones. The implementation of day-hospital care or out-of-hospital care addressed to the elderly will have to take in account these pathologies in order to be effective in both meeting treatment needs and reducing hospital expenditure.

[The evaluation of care needs in elderly people: the use of Geriatric Functional Evaluation Questionnaire].

The evaluation of the demand for assistance requires instruments and procedures scientifically validated as being effective. The aim of this paper is to present the results of a survey on the demand for assistance by a sector of the population, with an approach based on validated instruments and standardised procedures. The survey was carried out on a sample of 1,245 elderly persons (610 in Rome and 635 in Viterbo), who represent the over sixty-five year olds, resident in the Local Health Authority Roma D area and in the Local Health Authority of Viterbo. All the subjects were given the questionnaire for the Geriatric Functional Evaluation (GFE). Around 30% of over sixty-five year olds needs assistance. The Final Brief Evaluation indicates that 8% (CL 95%: 7.2-8.8) of the people interviewed need health and social services at the time of the study, and 20.6% more (CL95%: 19.5-21.7), should be carefully monitored in order to provide supportive, even if only social, services. Around 20.7% (CL95% 19.6-21.8) suffers from neurological pathologies and is characterised by a reduced functional capacity, as pointed out by the Multiple Correspondence Analysis. The combination of neuropathy and need of physical rehabilitation service is relevant part of the need for assistance. The approach used makes it possible to find out about situations of frailty in advance, so that a suitable plan of assistance in the area surveyed is possible.

[Pancreatic pseudocysts: the surgical timing].

Forty-three cases of pancreatic pseudocysts (PPC) are reviewed. Various emergency and elective surgical therapeutical options have been employed: while external drainage has confirmed to represent the best procedure in emergency occurrences, cystojejunostomy has proved to be the treatment that better provides both optimal functional results and minimal mortality/morbidity in elective situations. Our study also confirms that the thickness of the pseudocystic wall is the only feature apt to determine whether or not a PPC is susceptible of internal surgical derivation, and that abdominal ultrasound scanning is the most sensitive and reliable diagnostic method to ascertain this prerequisite, thus providing a well-timed strategy for elective derivative operations.

[Acute cholecystitis: elements for diagnosis and therapy].

The Authors report their experience in the surgical management of 439 patients with acute cholecystitis. Symptoms and laboratory findings at onset, preoperative diagnostic tools, associated disorders, surgical procedures as well as age-related postoperative morbidity and mortality and length of postoperative stay were analyzed. The most valuable investigation in the diagnosis of acute cholecystitis was ultrasound carried within the first 48 hrs, with positive results in 81% of cases. Tc-99m-HIDA biliary tract imaging proved to be a rapid, highly sensitive and specific, non invasive method of diagnosing acute cholecystitis in doubt cases. Morbidity (4.8%) and mortality (0%) rates in younger patients were inferior than those (22% vs 1.5%) observed in the elderly. Early and late results indicate that early cholecystectomy is the treatment of choice in acute cholecystitis.
