[Plasma cells leukaemia, cryoglobulins and antithrombin (author's transl)].
Although primitive plasma cells leukaemia is uncommon, it still stands in a particular place among malignant lymphoplasmocytary syndroms. It borrows from multiple myeloma and acute leukaemia some of its clinical and biological manifestations. Its course is quickly adverse, its treatment ineffective and the average life expectation is three months.

[Sciatica due to chronic spontaneous lumbar epidural haematoma. Report of a case simulating a protruded disk syndrome (author's transl)].
A case of spontaneous chronic lumbar epidural hematoma, in a 70-year-old woman is reported. The clinical, roentgenographic and anatomic findings of this case and of six others found in the available literature are studied. This clinical entity occurs in elderly and must be considered in the differential diagnosis of protruded disk syndromes.

[Bilharzial myelopathies (case report) (author's transl)].
Report of a case of biharzial myelitis appearing 6/8 weeks after bathing in an infected river. Recovery was complete after medical treatment with niridazol and hycanthone. The authors review the 47 detailed cases previously reported, selected among 60 cases observed from 1905 to 1963. They consider the clinical and pathological aspects and discuss the various pathogenic problems. Treatment requires specific antibilharzial compounds and anti-inflammatory drugs and, in compressive forms, sometimes surgery.

Poliovirus neutralizing antibody persistence after vaccination with the Sabin vaccine: a follow-up study.
In 1976, a cohort survey on the persistence of neutralizing antibodies in children regularly immunized 1 to 4 years earlier with the Sabin attenuated vaccine (OPV) was undertaken in the Venice mainland. Subsequent serological evaluations in the same cohort were carried out in 1983 and 1993. A macroneutralization test using a 1:4 initial serum dilution was utilized in the 1976 and 1983 survey years. In the 1993 survey a microneutralization test using a 1:2 initial dilution was utilized. In this survey, however, sera were tested using both the latter microneutralization test and the former test. Using the former method, the results indicate that the OPV-induced humoral immunity to poliovirus 1 and 2 remain fairly stable after the initial decrease, whereas antibodies to poliovirus 3 are further declining. Using the latter more sensitive method the seropositivity rates were found to be equal or close to 100 percent. The results of our follow-up survey thus indicate that the OPV-induced humoral immunity is long-lasting when tested with a highly sensitive and reproducible method. The clinical protection that ensues after OPV-immunization is probably lifelong similar to that which follows the natural infection.

Immunity status to poliovirus in Veneto region (north-east Italy). A seroepidemiological survey.
The immunity state to poliovirus types 1, 2, and 3 of a population aged 2 to 75 years was determined by examining 274 sera collected in the Venice mainland (North-East Italy). Altogether, the neutralizing antibody prevalences (at a titre > or = 1:2) for poliovirus 1, 2, and 3 were 99.0 percent (geometrical mean titres [GMT]: 72.1), 99.6 percent (GMT: 95.9) and 98.2 percent (GMT: 17.3), respectively, and all the age groups also showed very good levels of humoral immunity. High antibody titres (> or = 1:256) to one or more types of poliovirus were demonstrated in older age groups also, possibly indicating exposure to natural polioviruses or contact with vaccine strains. Although probably all the older subjects had practically acquired their antibodies as a result of natural infection and those under 30 through vaccination, these results indicate that the humoral immunity against poliomyelitis in our population is satisfactory, and the maintenance of such good protection level depends on an effective immunization program.

Immunity status to polioviruses among non-European union immigrants in Veneto Region (North-East Italy).
Widespread use of poliovirus vaccines has lead to a dramatic decline on the incidence of paralytic poliomyelitis in the Western Hemisphere. In Italy, the use of live attenuated vaccine (OPV) has lead to virtual eradication of poliomyelitis. However, wild poliovirus is still endemic in some less developed countries, and there is still a risk of importation of wild-virus poliomyelitis as result of immigration from these areas. Therefore, a serologic study of the immunologic status to poliovirus was carried out in 242 immigrants from less developed countries in the Veneto Region (North-East Italy). The overall prevalence of serum neutralizing antibodies was 98.3 percent for poliovirus type 1, 99.6 percent for type 2, and 95.9 percent for type 3. The modal titres were 1:128 (21.1 percent), 1:512 (26.4 percent), and 1:32 (22.3 percent) for poliovirus type 1, type 2, and type 3, respectively. No subject was simultaneously lacking neutralizing antibodies to all three polioviruses. The mean duration of stay in Italy before testing was 1.53 years (range 1 month to 7 years). These results show a good level of the immunity status, similar to those found in the Veneto general population. Although the risk of paralytic poliomyelitis in our population is very low, seronegative immigrants originating from areas of high endemicity could reintroduce wild poliovirus. It is therefore important to maintain a careful surveillance system on the importation of wild poliovirus and to plan vaccination programs for unprotected immigrants.

[Prevalent frequency of prosopagnosia in males].
In order to find out how frequent prosopagnosia is in males in comparison to females, all cases hitherto published have been reviewed and a remarkably greater frequency in males has been pointed out. Since the etiology has resulted to be in the majority of cases vascular, the epidemiology of vascular diseases as possible factor of this different incidence is discussed. It is concluded that the greater frequency observed in males seem to be a real fact inherent to prosopagnosia, and not related to other factors.

[Laparoscopic cholecystectomy in patients who previously underwent major laparotomy].
This paper describes the experience gained and the techniques used by the authors in the laparoscopic treatment of biliary calculosis in patients who previously underwent abdominal surgery, excluding cases with incisions below the horizontal line passing through the umbilicus (in these cases there are usually no adhesions to hinder operative laparoscopy of the gallbladder). Between October 1991 and July 1995,776 laparoscopies were performed on bile ducts (715 for calculosis of the gallbladder and 61 for cholecysto-choledochal calculosis). In 18 cases there was scarring of the abdominal wall due to previous major surgery (12 gastric resections, 3 resections of the colon, 1 splenectomy, 1 case of fundoplication for hiatal hernia, 1 resection of the ileum). In all cases access was by open laparoscopy to the lower right or periumbilical abdominal quadrant. When necessary, local viscerolysis was performed using various techniques with variations depending on the adhesions encountered. In all cases surgery was performed laparoscopically. In 2 cases a calculosis of the common bile duct was treated at the same time. The average duration of surgery was 70 min for cholelithiasis and 145 min for cholecysto-choledochal calculosis. On average patients were released from hospital 4 and 7 days after surgery respectively. No major or minor complications were encountered.

Mini-laparoscopic cholecystectomy.
BACKGROUND/AIMS: The authors describe their experience in performing cholecystectomy using mini-laparoscopy in selected cases of uncomplicated cholelithiasis. This involved making one 10 mm, one 5 mm and two 2 mm incisions. METHODOLOGY: From July 1996 to August 1997, 60 cholecystectomies were performed using mini-laparoscopy, out of a total of 203 video-laparocholecystectomies performed during the same period. RESULTS: Average length of the operations was 36 minutes from insertion of the first trocar to extraction of the gallbladder. All patients were discharged in the second day after surgery. No short-term intra- or post- operative complications occurred. CONCLUSIONS: The benefits of mini-cholecystectomy are potential advantages in improved appearance, reduced pain, better respiratory function, fewer wall complications. Therefore, the authors believe that mini-laparoscopy should not be assessed in terms of percentage of use or success, but rather considered as a part of the laparoscopic method to be used in selected cases.
