Cerebral arachnoid cyst: a lesion of the child's brain.
1989
39 patients with 42 arachnoid cysts have been reviewed in a retrospective study. All kinds of arachnoid cysts reported in the literature were also found in this study. These consist mainly of congenital primary and post-traumatic secondary cysts. Cysts which cause no major neurological deficits require conservative treatment of symptoms only. Cysts which cause major symptoms because of their space occupying nature, however, require surgical treatment. Craniotomy with removal of membranes to allow free physiological circulation of CSF is the treatment of choice in our hands. Cysto-peritoneal shunting is an alternative procedure for patients in a poor condition. More than 50% (23 out of 39 ca…
Relationships between ambulatory white coat effect and left ventricular mass in arterial hypertension
2003
The aim of our study was to analyze, in a group of 296 essential hypertensives, the relationship between left ventricular mass (LVM) and ambulatory white coat effect (WCE); that is the difference between the elevation of the first measurements of ambulatory blood pressure monitoring and the mean daytime pressure. The study population was separated into two groups according to the median of the WCE. The LVM was greater in the groups with higher systolic and diastolic ambulatory WCE. The significant association between ambulatory WCE and LVM was confirmed by the results of multiple regression analysis, suggesting that ambulatory WCE may not be an innocent phenomenon.
Lymphocyte beta-adrenergic receptors in young subjects with peripheral or central obesity: relationship with central haemodynamics and left ventricul…
1994
This study was designed to evaluate total (t) and surface (s) β-adrenergic receptor (BAR) density and their relationship with central haemodynamics and left ventricular function in young subjects with central or peripheral obesity. A total of 31 obese subjects (BMI ≥30.5 kg. m−2 for males and >27.3 kg. m−2 for females) aged less than 40 years and without other risk factors for cardiovascular diseases (smoking, hypertension, diabetes and lipid abnormalities) were studied. Nine had peripheral obesity and 22 central obesity according to WHR values; there were 20 lean controls (BMI <25 kg. m−2 for males and <24.7 kg. m−2 for females). Casual (c) and 24 h ambulatory mean blood pressures (MBP-24 …
Surgical treatment and follow-up of solitary bone cyst of the mandible:a report of seven cases.
2001
We have operated on and followed up seven patients with simple mandibular bone cysts. The clinical data are shown in Table 1. All cysts were asymptomatic, and were found as a result of routine radiographs. They were all in dentulous areas in the mandible (5 in the anterior zone). Only case 5 gave a clear history of trauma in the region of the cyst 7 years before diagnosis. Vitality of the pulp of adjacent teeth was confirmed in all cases except case 6, in whom endodontic orthograde treatment of the teeth included in the lesion zone had previously been done. In all cases, the radiographs showed a unilocular radiotransparent lesion with clearly defined margins
Three-dimensional images contribute to the diagnosis of mucous retention cyst in maxillary sinus
2011
Objective: To evaluate the detection of mucous retention cyst of maxillary sinus (MRCMS) using panoramic radiography and cone beam computed tomography (CBCT). Study Design: A digital database with 6,000 panoramic radiographs was reviewed for MRCMS. Suggestive images of MRCMS were detected on 185 radiographs, and patients were located and invited to return for follow-up. Thirty patients returned, and control panoramic radiographs were obtained 6 to 46 months after the initial radiograph. When MRCMS was found on control radiographs, CBCT scans were obtained. Cysts were measured and compared on radiographs and scans. The Wilcoxon, Spearman and Kolmorogov-Smirnov tests were used for statistical…
Prevalence and distribution of odontogenic cysts in Sicily: 1986-2005.
2008
The objective of this study was to assess the prevalence of odontogenic cysts (OCs) in Sicily and evaluate their distribution during a 20-year period. A cross-sectional retrospective study was carried out in 1,310 cysts of the jaw diagnosed in 12,197 individuals, who consecutively attended the Odontostomatologic Clinic of Palermo from 1986 to 2005. 1,273 cysts were classified as odontogenic, whereas only 37 were non-odontogenic. In the former group, the most frequent lesions were radicular cysts (84.5%), followed by dentigerous OCs (11.4%). Inflammatory radicular cysts were observed more in male gender, younger age at diagnosis and anterior maxilla as site of presentation. Unlike dentigerou…
Cystic vestibular schwannoma: classification, management, and facial nerve outcomes.
2009
OBJECTIVE: Review of postoperative morbidity and facial nerve outcomes of cystic vestibular schwannoma (CVS) patients compared with solid vestibular schwannoma (SVS) patients and a proposal for a new CVS classification system. STUDY DESIGN: Retrospective review. SETTING: Tertiary care facility. PATIENTS: Ninety-six patients with surgically treated CVS (1998-2008). Outcomes were assessed in a subpopulation of 57 patients with greater than or equal to 1-year follow-up compared with 57 SVS patients. INTERVENTION: Fifty-six CVS patients underwent the enlarged translabyrinthine approach with transapical extension (Type I), and 1 patient underwent a transcochlear/transzygomatic approach. MAIN OUT…
Endoscopic and endoscope-assisted neurosurgical treatment of suprasellar arachnoidal cysts (Mickey Mouse cysts).
2005
Suprasellar arachnoid cysts represent less than 10% of all intracranial arachnoid cysts. Some of them may be quiescent throughout life, some may become symptomatic as they become enlarged and some disappear spontaneously. In this study we discuss the surgical strategies for endoscopic and endoscope-assisted treatment of suprasellar (Mickey Mouse) cysts and analyze the clinical results and experience collected over some years in our department upon doing these operations routinely. Between December 1996 and December 2003, 13 patients (7 female and 6 male patients), mean age 29 years, underwent endoscopic or endoscope-assisted procedures for suprasellar cysts at our department. The indication…
Improving the disease awareness: how a communication campaign brings hidradenitis suppurativa to the light
2019
Background: Hidradenitis suppurativa is an inflammatory skin disease that presents a recurrence of painful and suppurating lesions in the apocrine gland-bearing regions, with a strong impact on the patients’ life quality. Despite its peculiar presentation, early forms are often underestimated by patients and this would inevitably result in late diagnosis and delayed therapy. Objectives: Improved communication around the disease could facilitate self-diagnosis and a quicker response from healthcare practitioners, especially in this moment when we dispose of effective treatment against this disease. Methods: A HS awareness campaign was conducted for 2 years with the help of a media agency and…
The supracondylar approach to the jugular tubercle and hypoglossal canal.
1998
BACKGROUND Circumscribed lesions of the hypoglossal canal and of the jugular tubercle still remain a surgical challenge. So far, transpetrosal, transcondylar suboccipital, and extreme lateral approaches have been used to access this region. These surgical procedures bear a high risk for neurological deficits. Therefore, we introduce a new minimally invasive extradural approach to the hypoglossal canal that also allows access to the lateral aspects of the jugular tubercle. METHODS After a paramedian retromastoid skin incision, a basal suboccipital craniectomy lateral to the foramen magnum toward the jugular tubercle is performed. With this approach the occipital condyle and the lateral osseo…
