PROGNOSTIC VALUE OF LUNG ULTRASOUND IN OLDER NURSING HOME RESIDENTS AFFECTED BY COVID-19

2020

Objectives: Lung ultrasonographic (LUS) imaging may play an important role in the management of patients with COVID-19–associated lung injury, particularly in some special populations. However, data regarding the prognostic role of the LUS in nursing home residents, one of the populations most affected by COVID-19, are not still available. Design: Retrospective. Settings and Participants: Nursing home residents affected by COVID-19 were followed up with an LUS from April 8 to May 14, 2020, in Chioggia, Venice. Methods: COVID-19 was diagnosed through a nasopharyngeal swab. LUS results were scored using a 12-zone method. For each of the 12 zones (2 posterior, 2 anterior, 2 lateral, for both l…

Late Complication after Superficial Femoral Artery (SFA) Aneurysm: Stent-graft Expulsion Outside the Skin.

2014

A 78-year-old man presented with a 7-cm aneurysm in the left superficial femoral artery, which was considered unfit and anatomically unsuitable for conven- tional open surgery for multiple comorbidities. The patient was treated with stent-graft [Viabhan stent-graft (WL Gore and Associates, Flagstaff, AZ)]. Two years from stent-graft implantation, the patient presented a purulent secretion and a spontaneous external expulsion through a fistulous channel. No claudication symptoms or hemorrhagic signs were present. The pus and device cultures were positive for Staphylococcus aureus sensitive to piperacillin/tazobac- tam. Patient management consisted of fistula drainage, systemic antibiotic the…

Negative Effect of Ranitidine on The Results of Urea Breath Test for The Diagnosis of Helicobacter Pylori

2001

In analogy with proton pump inhibitors, H2-antagonists may also be responsible for false-negative results on urea breath test for the detection of Helicobacter pylori. In this study we assessed the frequency and duration of false-negative urea breath tests in patients given different doses of ranitidine.A total of 120 consecutive dyspeptic patients infected with H. pylori on the basis of concomitant positive results of CLO-test, histology and urea breath test were recruited for this prospective, open, parallel-group study performed in an urban university gastroenterological clinic. They were randomized to receive an acute treatment with either ranitidine 300 mg once a day in the evening, ra…

Long-term follow-up of children with surgically treated vesicorenal reflux: postoperative incidence of urinary tract infections, renal scars and arte…

1989

With a mean follow-up of 10.8 years, 160 female and 29 male patients were investigated after successful correction of vesicoureterorenal reflux. All patients suffered from urinary tract infection (UTI) preoperatively, while postoperatively 42% of the patients developed further UTIs but with a significantly diminished rate of febrile infections. In comparison to a group of patients without postoperative UTI (n = 16), the uroepithelial cells of those patients with a high infection rate after reflux correction showed a significantly lower bacterial growth suppression (n = 37). Renal scars were found in 22% of the investigated renal units with operated ureters (n = 211). Of the preoperatively u…

Effect of Bacteremia in Elderly Patients With Urinary Tract Infection.

2016

The clinical effect of bacteremia on outcomes in urinary tract infection (UTI) is still debated. This study aims to examine the clinical effect of bacteremia in elderly patients with UTI requiring hospital admission.This retrospective observational study recorded the clinical features, microbiology and outcomes in a Spanish cohort of patients aged ≥65 years hospitalized for UTI in whom blood cultures were performed in the emergency department. The primary outcome of the study was in-hospital mortality.Of 333 patients, with a mean age of 81.6 years, 137 (41.1%) had positive blood cultures. Escherichia coli, with 223 (66.9%) cases, was the most common microorganism isolated. Independent risk …

Oral HPV Infection: Current Strategies for Prevention and Therapy

2012

Infection with High Risk (HR) Human Papillomaviruses (HPVs) is the main aetiological agent of Cervical Squamous Cell Carcinoma (CSCC) and also associated in a subgroup of other neoplasms, including Oropharyngeal Squamous cell Carcinoma (OPSCC). HPV infection, in genital as in oral mucosa, can also be subclinical or associated with benign proliferative lesions (common warts, condylomas, papillomas) caused mostly by infection with Low Risk (LR)-HPVs. In the last decades, extensive research has resulted in growing knowledge on HPV biology and specifically viral life cycle, biochemical properties of viral proteins and their interaction with the host proteins leading to potential new targets of …

Fascioliasis and Intestinal Parasitoses Affecting Schoolchildren in Atlixco, Puebla State, Mexico: Epidemiology and Treatment with Nitazoxanide

2013

Background The Atlixco municipality, Puebla State, at a mean altitude of 1840 m, was selected for a study of Fasciola hepatica infection in schoolchildren in Mexico. This area presents permanent water collections continuously receiving thaw water from Popocatepetl volcano (5426 m altitude) through the community supply channels, conforming an epidemiological scenario similar to those known in hyperendemic areas of Andean countries. Methodology and Findings A total of 865 6–14 year-old schoolchildren were analyzed with FasciDIG coproantigen test and Lumbreras rapid sedimentation technique, and quantitatively assessed with Kato-Katz. Fascioliasis prevalences ranged 2.94–13.33% according to loc…

Maggot therapy following orbital exenteration

2007

Orbital exenteration is a radical surgery reserved for the treatment of locally invasive or potentially life-threatening orbital tumours.1 Complications occur after 20–25% of exenterations and include tissue necrosis (6%) and infection (3–4%).2–4 In the present report, we describe the management of a post-exenteration orbital infection by the use of maggots. An 82-year-old multimorbid man presented with a fist-sized painless tumour of the left orbit (fig 1A). Computed tomography demonstrated an orbital mass clearly demarcated from the surrounding tissue (fig 1B). After biopsy, the neoplasm was classified as a borderline-malignant extrapleural solitary fibrous tumour. Therefore, a total orbi…

Influence of inadequate antimicrobial therapy on prognosis in elderly patients with severe urinary tract infections.

2013

Abstract Background Inadequate empirical antimicrobial therapy (IEAT) in intensive care unit (ICU) is associated with adverse outcomes. However, the influence of IEAT on prognosis for elderly patients with urinary tract infection (UTI) in non-ICU settings is unknown. Methods A retrospective cross-sectional study of elderly patients admitted to a non-ICU ward in a university hospital with a primary diagnosis of UTI over a 3-year period was done. Data relating to age, sex, background comorbidities, severity of infection, bacteremia, microorganisms isolated in urine, treatment given, length of stay and prognosis were obtained using chart review. Cases were segregated according to the adequacy …
