The authors report their laparoscopic access technique. It has to be considered a variation of the classical closed technique, with the introduction of the Veress needle and the first trocar directly at the level of the fascia which is kept in traction by two Kochers.
It is widely known that US results strictly depends on operators and that each operator follows individual pathways. Therefore the authors have tried to develop high-interactivity tools, allowing the "customization" of learning to the user's demands. Progress linked to microprocessors' technology allowed a wide spread of cost-effective electronic processors with high graphic performances, capable of supporting sophisticated softwares which are useful to develop multimedial programs. Our experiment is aimed at integrating a multimedial management system for US studies, with the training activity of the medical staff US-expert. The system is structured on a hardware platform based on the Motorola microprocessor, class 68040, an application software developed by Apple. The environment for multimedial applications development uses the "Hypercard" interface of graphic presentation, by Apple. The software allows the realization of a multimedial environment of learning, where US images are associated with graphics, drawing and text references. The application allows a multimedial environment of learning for normal eidodiagnostic anatomy of the female reproductive system, where different courses can be followed autonomously. On the basis of a check performed on a group of students, although in a preliminary stage, the combination of conventional didactic material with either a paper or television support, with devices allowing the connection of texts, graphics and images in a dynamic way, proved to be very useful and to allow personal courses of learning, which can be always modified in an interactive way.
Psittacosis or ornithosis is a bird disease caused by Chlamydia psittaci which can be transmitted to man. Little is known of the epidemiology of the disease in this region, but occasional cases which have been brought to the authors' attention have prompted an epidemiological study on the subject. The preliminary results indicate a surprising percentage, over 8%, of antibodies in infants and children. This percentage varies little in relation to place of residence, rural or urban, or the presence of animals, but confirms the high risk in parrot-owning households where anti-Chlamydia antibodies are found in 37.5% of children.

OBJECTIVE: To investigate the relationship between specific cytopathologic changes, koilocyte counts and human papillomavirus (HPV) types in HIV-positive and -negative women. STUDY DESIGN: A cohort of 459 women (266 HIV+ and 193 HIV-), were examined in a multicentric study (Early Diagnosis of Neoplasia in AIDS) involving 14 gynecologic centers. Altogether, 97 women had cervical smears consistent with squamous intraepithelial lesions (SIL). Koilocytes were found in 60/97 SIL slides, subjected to quantitative counting in 30 predetermined fields. HPV genotype was determined by polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) analysis. RESULTS: SIL lesions were four times more frequent (29%) in HIV-positive women than in HIV-negative women (10%) (odds ratio = 3.80). HPV DNA was equally frequent in both groups. There was a strong association between the number of koilocytes and HIV serostatus in both high grade and low grade SIL diagnoses. The presence of eight or more koilocytes had a specificity of 93% and sensitivity of 76% toward the diagnosis of HIV-positive status. No HIV-negative woman had a count > 8 koilocytes. No association was shown between koilocyte count and HPV genotype. CONCLUSION: An elevated number of koilocytes could suggest the possibility of HIV infection. Pap smear examination might give the first clue to HIV positivity in otherwise-unsuspected cases.
BACKGROUND: Pilonidal sinus (PS) disease of the sacrococcigeal region is an acquired condition resulting from penetration of shed hair shafts through the skin. Different types of operations have been described in the letterature. More recently fibrin glue has been used with succesfull. Aim of this study was to assess the effectiveness of fibrin glue for the treatment of pilonidal sinus. PATIENTS AND METHODS: Eight patients age ranged 21,8 +/- 6,5 affected by PS disease of sacrococcigeal region were included in this study. All patients undergoing surgical operation under local anaesthesia. Following administration of 1% methylene blue through the main opening, a small vertical elliptical incision is maked including the entire sinus opening and an excision of PS was performed without entering the sinus cavity, removing a minimal amount of subcutaneous tissue. Afterwards the highly concentrated fibrin glue, containing 1,000 U/ml of thrombin was applied to cover the wound. Post-operative pain, analgesic consumption, duration of hospital stay, failure healing, the rate and time of recurrence, time to healing, time to return to work and post-operative complications were recordered. RESULTS: All patients expressed satisfaction with the procedure. Mean hospital stay was 5.4 +/- 2.1 hours. Healing was achieved after 25.8 +/- 13.2 days. The post-operative pain mean score was 3.8 +/- 2.1 in first day, 2,9 +/- 1,8 in third day and 1,3 +/- 0,8 in the seventh day. The mean analgesic consumption per week was 5,6 +/- 3,2 medications. Mean time to return to work was 5,3 +/- 2,1 days. CONCLUSION: The minimal excision of PS and application of fibrin glue is a non-invasive effective treatment, easy and simple to performe and not associated to recurrences. For these reasons this procedure in our opinion as the first line treatment for pilonidal sinus disease.
The aim of this study is to evaluate, after laparoscopic (CL) or open (CO) cholecystectomy, the incidence of pulmonary atelectasis and hypoxaemia which are strictly related to the onset of pulmonary complications. Two groups of 20 consecutive patients affected by symptomatic and not complicated gallstone disease were cholecystectomized either using CO or CL. Hypoxaemia was assessed preoperatively and after operation. Postoperative determination was performed at the 4th, 8th, 12th and 24th hour and then every 12 hours until discharge from hospital. A not informed radiologist evaluated atelectasis through two X-rays, preoperatively and postoperatively at the 3rd day. Atelectasis cases were divided in micro, focal, segmental, lobar and of the entire lung. Statistic analysis was performed using the "t" Student test. No mortality or intraoperative complications occurred. The two groups were similar for age, sex, smoker percentage, obesity, preexisting pulmonary dysfunctions and anaesthesiological risk (ASA). Operative time resulted in longer in CL compared to CO patients although in an insignificant way. PO2 value resulted significatively reduced (P < 0.05) at 4th, 8th, 12th and 24th postoperative hour after CO, while subsequent measurements did not show significant differences. There was no evidence of PO2 significative reduction after CL. After operation atelectasis was found in 11 patients (55%) of CL group (P < 0.05) and in 17 patients (85%) of CO group (P < 0.001). Atelectasis observed in the group of 11 CL patients was represented by 7 micro and 4 focal types, while in the CO group 7 micro, 8 focal and 2 segmental types were found. This study suggests that CL alters the pulmonary function less than CO.
