RESUMO
We evaluated the predictive value of several clinical, radiological and laboratory parameters on the risk of predict intracranial hemorrhage (ICH) in patients with atrial fibrillation (AF). We conducted a case-control study on a consecutive hospital based series of patients with AF and ICH. A random sample of subjects with AF without ischemic or hemorrhagic stroke was selected from the same hospital in the same period to perform as the control group, with a ratio of two controls per case. All patients underwent the same evaluation protocol. Patients without neuroimaging exams were excluded. During the study period we identified 37 subjects with AF and ICH. 74 subjects without stroke events were randomly chosen among subjects with AF. Among cases 56.8% were female; mean age was 83.1 years. Patients with ICH were more often on anticoagulant therapy (75.7%), compared with controls (45.9%; p = 0.0002). On CT scans, cases had a greater severity of leukoaraiosis at the Blennow scale (p < 0.0001) and a higher frequency of lacunar infarcts (p = 0.006). No significant association was found between MRI parameters or the HAS-BLED score and the occurrence of ICH. CT scan is more useful than MRI and HAS-BLED score to predict ICH in patients with AF on antithrombotic therapy.

BACKGROUND: The management of primary aldosteronism is currently achieved by both medical and surgical treatment. Laparoscopy has in recent years unquestionably become the gold standard in adrenal surgery for benign lesions. This study aims to evaluate our clinical results among patients who underwent laparoscopic adrenalectomy (LA) for primary aldosteronism. METHODS: From January 1994 to January 2006, amid LA series, 59 primary aldosteronism patients were treated in our institution. Patients were 33 males and 26 females with mean age 49.3 yr (19-78). The mean body mass index was 25.9 kg/m2 (20.5-33.3). The mean size of lesion was 2.9 cm (1-5.5). Clinical symptoms were as follows: hypertension and symptomatic/asymptomatic hypokalemia (54), hypokalemia (5). RESULTS: Thirty-five left and 24 right LA were performed. On the left side, 22 procedures were carried out by anterior approach, 9 by anterior submesocolic route, and 4 by means of flank approach. All right procedures were completed by the anterior supine approach. The mean operative time was 103.5 min for left and 92.8 min for right adrenalectomy. There was one major complication, a colonic post-operative fistula, regarding a left adrenalectomy case. The mean post-operative hospital stay was 3 days (1-9). The cure rate of hypertension and hypokalemia was similar to the current literature results. CONCLUSIONS: LA is a safe and effective option in the treatment of primary aldosteronism. Appropriate selection of patients, larger adrenal masses and duration of symptoms are determining factors in the success rate of hypertension management.

BACKGROUND: Laparoscopy is commonly recognized as the gold standard in adrenal surgery. The most used surgical access is at present the so-called flank approach. The aim of this study was to compare the flank approach and the anterior sub-mesocolic access carrying out left laparoscopic adrenalectomy (LA). METHODS: From January 2003 to January 2006 50 eligible left LAs were randomized to the flank (n = 25, group A) or sub-mesocolic transperitoneal approach (n = 25, group B). The two groups were similar concerning patient and lesion features. Comparing the two approaches, the main parameters analyzed, adjusted for tumor size and histology, were operating time (OpT), complication rate, and hospital stay. RESULTS: There were no converted procedures. Mean overall OpT was 76.4 min (54-96 min) versus 65.6 min (45-95 min) in group A and B, respectively (p = 0.001), while the OpT required to tie the adrenal vein was 42.8 min (26-55 min) and 24.5 min (16-41 min) (p = 0.000). Oral feeding resumed within 12-24 h in both groups. Mean hospital stay was 3 and 2.4 days in groups A and B, respectively (p = 0.04). Mean tumor size was similar in group A and B: 3.6 cm (1.5-6.5 cm) and 3.8 cm (2-6 cm), respectively. Definitive histology in groups A and B were: Cushing adenoma (6 and 4), Conn adenoma (5 and 6), pheochromocytoma (4 and 9), and incidentaloma (8 and 5, respectively). A myelolipoma and an adrenogenital adenoma were observed in group A and one carcinoma was observed in group B. CONCLUSIONS: Sub-mesocolic approach provides a statistically significant shorter OpT and hospital stay. Identification and early closure of the adrenal vein by means of a really minimal dissection and no-touch gland technique resulted in the main benefits of this approach.

Increasing evidence suggests that uric acid (UA) is a relevant risk factor for arteriolosclerosis and recent studies have demonstrated the positive relationship between UA concentrations and the severity of leukoaraiosis. However, the association between lacunar infarcts (LI) and UA levels has seldom been reported in the literature. The aim of our study was to assess whether serum UA levels may be related to the presence of LI. We recruited 242 patients (113 males and 129 females, aged 82.83 ± 6.49 years) from our Geriatric Department for whom CAT scans (CT) were available. Clinical and laboratory data was collected. Patients CT images were examined to identify the presence, the size, the number, and the location of LI. LI without neurological symptoms were considered silent LI. Serum UA levels were found to be positively associated with the presence (p = 0.0001), the number (p = 0.001), the size (p = 0.001), and the location of LI in the basal ganglia (p = 0.0038), the deep white matter (DWM) (p < 0.0001), and the pons (p = 0.0156). A significant association was also found between UA and silent LI (p = 0.0002). The prevalence of LI increased starting from UA levels of 5.7 mg/dl. Stepwise multiple regression analysis confirmed that UA was independently related with the presence, the number, the size, LI in the basal ganglia, the DWM, the pons, and with silent LI. Our study suggests a positive association between UA levels and LI, which is independent of traditional cardiovascular risk factors. This data suggests that UA plays an influential role on the physiopathology of LI and could represent a potential target to prevent cerebral microinfarcts.

Nowadays, the role of surgery in the treatment of adrenal incidentalomas (AI), considering their biologic behavior, is still debated. Surgery is mandatory in cases of hyperfunctioning adrenal masses, in the presence of suspect radiological malignancy, in cases of discordant computed tomography (CT) and scintigraphy findings and when the maximum diameter is 4 cm or more. On the other hand, studies have suggested relative inaccuracy of conventional CT in evaluating the size. The aim of this paper was to evaluate the safety and effectiveness of laparoscopic adrenalectomy (LA) in the treatment of AI by reviewing our experience. Over the period from 1995 to 2005 we laparoscopically managed 78 AI by anterior transperitoneal approach. Two LA (2.6%) were converted to open surgery. Neither intra- nor post-operative major complications were observed. The mean size of lesions was 5.5 cm (range 3-9). Twenty-one large adrenal lesions (exceeding 6 cm) were removed (27%). Definitive histology resulted as follows: adrenocortical adenoma (63), pheochromocytoma (5), nodular hyperplasia (4), myelolipoma (3), cysts (2), and adrenocortical carcinoma (1, with a size of 3 cm). The patients were followed-up by hormonal and radiological evaluation every 12 months (6 for malignancy); their follow-up (median 60.4 months, range 6-123) was uneventful. Also larger AI were treated safely. Laparoscopy has been safe and effective in the treatment of AI in our experience, according to specific literature.

An association of obstructive sleep apnea syndrome (OSAS) and other sleep-disordered breathing (SDB) with Parkinson's disease (PD) has been reported in some small studies. In the present study we investigated the occurrence of SDB in a large consecutive outpatient series. This is a case-control study in subjects attending a neurological clinic where all patients were screened for SDB by means of sleep-wake history, Epworth Sleepiness Scale, and full-night polysomnography, when indicated. 3194 patients were recruited. Of these, 194 were affected by PD and 77 by other parkinsonisms. Snoring, excessive daytime sleepiness and OSAS were more common in patients with PD or parkinsonisms (40.59, 5.9, and 4.06%) than in controls (35.58, 2.19, and 2.09%). Our study suggests an increased frequency of OSAS and other SDB in PD and parkinsonisms. Early detection and management of these disorders may have a substantial impact on quality of life and survival in these patients.

AIM: The aim of our study was to evaluate the advantages and disadvantages of open appendectomy versus laparoscopic appendectomy in the surgical treatment of acute appendicitis. We have compared the following items: operating time, postoperative pain, length of hospital stay, postoperative complications and costs. METHODS: The study was conducted on 435 patients admitted in our Department from December 1993 to December 2003 with diagnosis of acute appendicitis: 339 (77.9%) cases were operated with laparoscopic approach (LA group) and 96 (22.1%) cases with open approach (OA group) according to personal experience of surgeons on laparoscopic technique and patient's anthropometrical conformation. RESULTS: Mean operative time in LA group was 50 minutes (range 25-195) and 65 minutes (range 35-160) for OA group. In 15 patients (4.4%), the operation had to be converted to open approach. The morbidity was observed in 4.4% of patients for the LA group and 14.6% for the OA group. Hospital stay was faster for patients having laparoscopic appendectomy (2.5 days vs 3.5 days). Pain in the 1st and 2nd postoperative days, evaluated on the use of pain medication, was less in patient in LA group whereas the costs were higher in the LA group than in OA group. CONCLUSIONS: In our experience the laparoscopic approach to acute appendicitis can be considered safe and effective with diagnostic and therapeutic value. It significantly offers all the advantages of mini-invasive surgery reported in literature.
