Trauma in elderly patients: a study of prevalence, comorbidities and gender differences.

AIM: Trauma, in geriatric patients, increases with age, and is a leading cause of disability and institutionalization, resulting in morbidity and mortality. The aim of our study was to analyse the prevalence of trauma, the related risk factors, mortality and sex differences in the prevalence in a geriatric population. PATIENTS AND METHOD: We observed 4,554 patients (≥65 years) with home injuries or car accidents. Patients were evaluated with ISS (Injury Severity Score) and major trauma with ATLS (Advanced Trauma Life Support). The instrumental investigation was in the first instance, targeted X-Ray or whole-body CT. RESULTS: In over four years of study we treated 4,554 geriatric: 2,809 females and 1,745 Males. When the type of trauma was analysed the most common was head injury, followed by fractures of lower and upper limbs. In our experience hospitalization mainly involved patients over 80. In all patients mortality during assessment was 0.06%. DISCUSSION: The geriatric patient is often defined as a "frail elderly", for the presence of a greater "injury sensitivity". This is due to the simultaneous presence of comorbidity, progressive loss of full autonomy and exposure to a high risk of traumatic events. Optimal management of the trauma patient can considerable reduce mortality and morbidity. CONCLUSIONS: Falls and injuries in geriatric age are more frequent in women than in men. Among typical elder comorbidities, osteoporosis certainly causes a female preponderance in the prevalence of fractures. Our discharge data demonstrate that disability, which requires transfer to health care institutions, has a greater effect on women than men.

PRIMARY NOCTURNAL ENURESIS IN CHILDREN WITH ALLERGIC RHINITIS AND SEVERE ADENOTONSILLAR HYPERTROPHY: A SINGLE CENTER PILOT STUDY.

Nocturnal enuresis is defined as intermittent urinary incontinence during sleep that occurs at least twice a week for three consecutive months. There is no unifying etiology for nocturnal enuresis in the pediatric population and the disorder is likely to be multifactorial. We aimed to investigate the relationship between primary nocturnal enuresis, allergic rhinitis, and related complications in a paediatric case series from a single Center. We retrospectively reviewed and prospectively followed-up at our Institution (i) 32 children (14 females, 18 males; mean age 6.31±1.21 yrs) affected by allergic rhinitis with adenoidal hypertrophygrade I-II (group A) and (ii) 27 children (11 females, 16 males; mean age 6.52±1.33 yrs) affected by allergic rhinitis with adenoidal hypertrophy grade III-IV (group B). Allergic rhinitis was diagnosed on the basis of (a) typical nasal symptoms due to atopic sensitization (e.g., rhinorrhea , itching, sneezing fits, and nasal congestion and obstruction) and (b) positive skin prick testing and/or increased level of total serum IgE. We identified discrepancies between group A and group B in terms of risk of primary nocturnal enuresis. In fact, only 1 child of group A (3.12%) reported uncomplicated primary nocturnal enuresis; conversely, 6 children of group B (22.22%) showed a history of uncomplicated primary nocturnal enuresis (p=0.040). There was no statistically significant difference between the two groups in terms of atopic sensitization and serum total IgE levels (p=0.43). Allergic rhinitis may potentially influence the onset and the natural history of nocturnal enuresis in some children. Children with allergic rhinitis and more severe respiratory manifestations, seem to be more prone to developing primary nocturnal enuresis, likely due to potential multi-factorial causes (e.g., sleep disorders, chronic phlogosis, immune deregulation).

ALLERGIC RHINITIS AND ADENOID HYPERTROPHY IN CHILDREN: IS ADENOIDECTOMY ALWAYS REALLY USEFUL?

Allergic rhinitis (AR) and adenoid hypertrophy (AH) are common in children and are often associated with each other. Recent studies have shown improvement of respiratory symptoms and reduction in the adenoid volume after anti-allergic medical therapy (intranasal corticosteroids, antihistamines). The aim of our retrospective study is to evaluate the effectiveness of adenoidectomy on respiratory symptoms in pediatric patients with AR. We recruited 404 pediatric patients with AR, and we divided them into 4 groups (1. intermittent-mild rhinitis; 2. intermittent-moderate/severe rhinitis; 3. persistent-mild rhinitis; 4. persistent-moderate/severe rhinitis), using ARIA classification. For each patient we evaluated: age at onset of AR; family history of allergy; the presence of other allergic diseases; serum total IgE values; skin prick test (SPT) results; presence of AH evaluated by rhino-laringeal fibroscopy; adenoidectomy and its efficacy on respiratory symptoms. Our data show an association between AR and AH: 90 of 404 (22%) children with AR had AH of a degree greater than 2nd. A significant percentage (80%) of children suffering from AR did not present satisfactory benefits from adenoidectomy. They reported persistence or recurrence of rhinitic symptoms after surgery or only partial benefits, especially of recurrent respiratory tract infections and nasal obstruction. The local allergic persistent inflammation on nasal mucosa and adenoid tissue is probably the cause of the unsatisfactory results of adenoidectomy, therefore surgery cannot be the first therapeutic step for these children. It is important to extinguish the local inflammation by medical anti-allergic therapy to obtain improvements of nasal symptoms and to prevent adenoid regrowth.

CT-MR integrated diagnostic imaging of the oral cavity: neoplastic disease.

The oral cavity is a complex anatomical region consisting of different anatomical sites and subsites. Cancer undoubtedly represents the most frequent and relevant disease of this region. Clinical examination is often the first approach to oral cavity tumours. Cross-sectional computed tomography (CT) and magnetic resonance imaging (MRI) play a key role in staging locoregional disease by demonstrating submucosal spread and involvement of deep layers; evaluation of specific pathways of spread to peculiar anatomical subsites is also fundamental information that can be obtained with these techniques. The purpose of this paper is to illustrate CT and MRI findings of anatomical subsites involved by tumours of the oral cavity.

Contrast-enhanced ultrasonography (voiding urosonography) of vesicoureteral reflux: state of the art.

Three methods are currently used to identify vesicoureteral reflux (VUR) in children, namely, radiographic voiding cystourethrography, radionuclide voiding cystography and, more recently, echo-enhanced voiding urosonography (VUS). Recent advances in tissue-harmonic and contrast-specific imaging techniques, together with the development of second-generation contrast agents, have improved the potential of ultrasonography both in the diagnosis and grading of VUR in children. Today, VUS is able to accurately assess the grade of reflux and the state of the urethra, previously considered fundamental limitations to the extensive use of this technique. The aim of our paper is to review the role of ultrasonography in the diagnosis of VUR, from the initial experiences up to the recent use of second-generation microbubbles combined with contrast-specific low-mechanical-index software. We discuss the advantages and limits of VUS with respect to radiographic and radionuclide imaging in the light of an analysis of the most recent literature, and we described the new VUS study technique using second-generation contrast media. Growing requests by paediatric nephrologists and surgeons require that even general radiologists become familiar with this technique.

A case of bilateral prenatal testicular torsion: Ultrasonographic features, histopathological findings and management.

OBJECTIVES: The aim of this study was to demonstrate the ultrasonographic features of prenatal bilateral torsion of the testis, and its histological correlation and management. PATIENT: A newborn presented at delivery with both testes enlarged, swollen and tender. Prenatal ultrasound (US) showed enlarged, hyperechoic testes. Colour Doppler US examination was performed. RESULTS: US revealed both testes to be heterogeneous. Colour Doppler US did not reveal any flow signal. On inguinal exploration both testes appeared necrotic. Histology showed recognizable seminiferous tubules and Leydig cells. CONCLUSION: We believe that both testes should be left in situ after bilateral detorsion even if their macroscopic appearance is necrotic.

[Brucellosis and splenic infarction: a case in pediatric age]. / Brucellosi ed infarto splenico. Descrizione di un caso pediatrico.

Splenic infarction has been associated with haematologic and tromboembolic disorders and, more rarely, with infectious diseases. A case of splenic infartion during an attack of brucellosis is reported. Symptoms included persistent left upper quadrant pain and fever. An abdomen scan confirmed the presence of a triangular area of hypodensity in the spleen. Serum and culture exams confirmed the diagnosis of brucellosis. The patient recovered once a course of antibiotic therapy was completed, after 2 and half months.

Intrahepatic portal vein aneurysm: three-dimensional power Doppler demonstration in four cases.

We describe four cases of portal vein aneurysm that were studied with ultrasonography, color Doppler, computed tomography, and magnetic resonance imaging as well as three-dimensional power Doppler. Three-dimensional ultrasonography showed the portal aneurysm and its relationship to its portal branches in all patients and showed the portosystemic communication in three. In all cases, computed tomography or magnetic resonance imaging confirmed the three-dimensional ultrasonographic findings.

[Doppler power with contrast media in the characterization of renal masses]. / Power Doppler con mezzo di contrasto nella caratterizzazione delle masse renali.

PURPOSE: To report the results of a prospective study investigating the potentials of contrast-enhanced power Doppler in the diagnosis of expansive renal lesions. MATERIAL AND METHODS: From 1997 to October 30, 1999, we studied 59 expansive renal lesions (28 malignant, 31 benign) in 48 patients (mean age 55 years, range 10-79) with power Doppler US before and after the administration of an echo-enhancing agent (Levovist, Schering AG, Berlin, Germany). We identified 5 patterns of vascular architecture of the lesions, both before and after contrast agent administration, following the classification by Jinzaki e Coll. RESULTS AND DISCUSSION: Power Doppler US showed vascular structures in 34 patients. The administration of Levovist revealed vessels in 12/25 lesions which had none at baseline studies and in 6 cases vascularity was particularly evident. Color signals were enhanced in all the 34 vascularized lesions, which allowed better definition of vascular patterns. The characterization of vascular patterns with baseline power Doppler US helped improve diagnostic accuracy compared to gray-scale US (58% versus 32%) for hyperechoic lesions, complex cysts and pseudomasses. Independent of contrast agent administration, the integration of gray-scale and power Doppler modes increased diagnostic accuracy even further (76% correct diagnoses). CONCLUSIONS: In our series, the US contrast agent did not increase the diagnostic accuracy of power Doppler in the differential diagnosis of hyperechoic renal lesions; conversely, Levovist can be advantageous for the characterization of suspected pseudomasses and complex cysts.

[Urinary hydrometrocolpos by persistent urogenital sinus; prenatal diagnosis and neonatal management]. / Idrometrocolpo urinoso da persistenza del seno urogenitale: diagnosi prenatale e management neonatale.

Urogenital Sinus (UGS) malformation can be ascribed to an arrest of normal embryonic vaginal development. Neonates with UGS frequently have ambiguous genitalia, rarely the vulva may be normal. The aim of this work is to define the role of prenatal sonography in the diagnosis of UGS associated with hydrocolpos and/or hydrometrocolpos. The Authors report their experience on 3 cases of UGS without ambiguous genitalia with hydrometrocolpos, in which prenatal sonography had shown a cystic dilatation in the pelvis. After birth the 3 neonates presented with female genitalia and a single orifice between the labia. The pelvis sonography showed in all the cases an hydrometrocolpos with a large vagina and a compressed and anteriorly located bladder. Voiding cystourethrogram, genitography and genitoscopy confirmed the presence of an UGS with urinary retention inside the vagina and stenosis of the distal portion of the vagina itself. An early drainage of the capacious vagina was performed in the three patients. There are very few reports in the literature of UGS with hydrometrocolpos diagnosed in utero. The cystic dilatation of the vagina is always misdiagnosed with a distended bladder. In utero, infact, the bladder can not be identified being displaced anteriorly by the vagina. The presence of a fluid-debris level inside the cystic anechoic mass must be considered a crucial finding. Multiple echoes are due to vaginal secretions. Prenatal ultrasound has then a definitive role in detecting an obstructed genital tract. This allows to rapidly drain the vagina relieving urinary tract obstruction.

Subcapsular renal spread of a pancreatic pseudocyst.

In pancreatitis, the fluid collection may extend to unusual sites and organs and form a pseudocyst. We present US and CT findings of a pancreatic tail pseudocyst extending into the subcapsular space of the left kidney.
