Mycoplasma pneumonias distribution, epidemiology and prevalence in a triennial survey.
2005
OBJECTIVES. To evaluate: (1) the incidence of pneumonia monthly distribution; (2) the rate of pneumonitis due to Mycoplasma Pneumoniae; (3) the suitability of choosing an empirical-based antibiotic-therapy; (4) the need of a critical revision of Mycoplasma serological data. PATIENTS AND METHODS. We studied 188 patients admitted to the Palermo University Pediatrics Department, from september 1998 to august 2001, with admission diagnosis of pneumonia. RESULTS. The highest incidence of pneumonia was in december and march as in both months 28 cases occurred in the whole period 1998-2001 (average of 9.3 cases per each month). The highest rate of pneumonias by Mycoplasma Pneumoniae was in may wit…
Mycoplasma pneumoniae and Chlamydia pneumoniae infections in children with pneumonia. Mowgli Study Group.
2001
The most common clinical signs, host responses and radiographic patterns were studied in 203 Italian children hospitalized for community-acquired pneumonia in order to clarify the role of clinical and radiological characteristics in the diagnosis of Mycoplasma pneumoniae and/or Chlamydia pneumoniae infections. Antibody measurements in paired sera and polymerase chain reaction on nasopharyngeal aspirates were used to establish the diagnoses of acute. M. pneumoniae and C. pneumoniae infection, and the aetiologic data were correlated with the clinical, laboratory and radiographic data obtained on admission. No significant association was observed between evidence of M. pneumoniae and/or C. pne…
Aging-induced Up-regulation of Nuclear Binding Activities of Oxidative Stress Responsive NF-kB Transcription Factor in Mouse Cardiac Muscle
1996
The accumulation of lipofuscin to cardiomyocytes is a classical parameter of aging and is believed to reflect oxidative stress. NF-kB transcription factor complex is one of the cellular sensors which responds to oxidative stress and regulates gene expression. Our purpose was to study whether aging affects the level and distribution of DNA binding activities of NF-kB transcription factors both in cardiac sarcoplasm and nuclear extracts. We used electrophoretic mobility shift assays (EMSA) to characterize the DNA binding activities of NF-kB and two other transcription factors. AP-1 and Sp-1, in the myocardium of 4 months and 24 months old male and female NMRI-mice. The protein levels of p50, …
Evaluation of cell proliferation rate in non-dysplastic leukoplakias
2008
Objective: Analyze whether the most frequent cases of non-dysplastic leukoplakias, hyperkeratosis (H), acanthosis (A), and hyperkeratosis with acanthosis (HA) have similar cell proliferation rates and to compare them with epithelial dysplastic (ED) leukoplakias and normal oral epithelium (NOE).Study design: The sample comprised 10 cases of normal oral epithelium, 10 cases of hyperkeratosis, 10 cases of acanthosis, 10 cases of hyperkeratosis with acanthosis and 10 cases of epithelial dysplasia. The mean number of AgNORs per nucleus (mAgNOR) and the mean percentage of cells with 1, 2, 3 and 4 or more AgNORs per nucleus (pAgNOR) were recorded. Results: The results of mAgNOR showed differences …
H3 and H3.3 histone mRNA amounts and ratio in oral squamous cell carcinoma and leukoplakia.
2006
Histone variants (e.g. H3) play an important role in chromatin structure and gene expression regulation of normal cells. Aims of this study were to: (1) estimate H3 and H3.3 histone mRNA expressions and their ratio in oral squamous cell carcinoma (OSCC) and oral leukoplakia (OL); (2) investigate whether H3 and H3.3 variants could play a role in the pathogenesis of OSCC and OL, also conditionally to HPV infection, age, gender, and main habits (tobacco smoking and alcohol drinking) in human beings studied. Twenty-three cases of OSCC and 20 cases of OL were examined in lesion site (LS) and juxtaposed clinically undamaged site (JUS) by RT-PCR for H3 and H3.3 histone mRNA; 13 healthy oral mucosa…
Impact of Viral and Bacterial Infectious Burden on Long-Term Prognosis in Patients With Coronary Artery Disease
2001
Background —The number of infectious pathogens to which an individual has been exposed (infectious burden) may correlate with coronary artery disease (CAD). In a prospective study, we evaluated the effect of 8 pathogens and the aggregate pathogen burden on the risk for future fatal cardiac events among patients with angiographically documented CAD. Methods and Results —In 1018 patients, IgG or IgA antibodies to herpes simplex virus types 1 and 2, cytomegalovirus, Epstein-Barr virus, Haemophilus influenzae , Chlamydia pneumoniae , Mycoplasma pneumoniae , and Helicobacter pylori were determined. Moreover, highly sensitive C-reactive protein was measured. Follow-up information on cardiovascul…
Extended-spectrum beta-lactamase-producing and carbapenemase-producing Enterobacter cloacae ventriculitis successfully treated with intraventricular …
2014
SummaryWe present a case of post-neurosurgical ventriculitis caused by carbapenemase-producing Enterobacter cloacae successfully treated with intraventricular colistin. Enterobacter spp are intrinsically resistant to aminopenicillins, cefazolin, and cefoxitin due to the production of constitutive chromosomal AmpC beta-lactamases. Moreover, extended-spectrum beta-lactamase-producing Enterobacter spp have been identified in the USA and Europe, and carbapenems are considered the drug of choice in these cases. Our isolate was sensitive only to fosfomycin, tigecycline, and colistin, and 6 days of intravenous colistin had failed to eradicate the infection. This case provides clinical evidence to …
Changes in pulmonary calcitonin gene-related peptide and protein gene product 9.5 innervation in rats infected with Mycoplasma pulmonis.
1996
Changes in the expression of calcitonin gene-related peptide (CGRP) and polyneural protein gene product 9.5 (PGP) in hilar peribronchial innervation was investigated by immunohistochemistry in specific pathogen-free rats chronically infected with Mycoplasma pulmonis. Image analysis of immunostained sections revealed a reduction of approximately 62% in the amount of CGRP- and PGP-immunoreactive innervation of the peribronchial area in the infected animals. The portion of the total bronchial perimeter occupied by bronchus-associated lymphoid tissue was increased six-fold. The decrease in the CGRP-immunoreactive area could be the result either of an enhanced CGRP release or of a loss of nerve …
Blood metal levels after minimally invasive repair of pectus excavatum
2021
Abstract OBJECTIVES Minimally invasive repair of pectus excavatum (MIRPE) is the most popular surgical approach for paediatric patients with pectus excavatum. A substernal stainless still bar is inserted and left in place for 3 years and then removed. Our goal was to investigate blood metal levels after MIRPE and to correlate them with surgical details, such as the numbers of bars and stabilizers and the length of time the bar was in place. METHODS Blood levels of iron, chromium, manganese, molybdenum and nickel were analysed in 130 teenagers (108 boys and 22 girls) who had MIRPE using inductively coupled plasma mass spectrometry. A total of 62 patients were operated on using MIRPE (study…
Reconstruction with a pectoralis major myocutaneous flap after left first rib and clavicular chest wall resection for a metastasis from laryngeal can…
2016
We presented a case of recurrent metastasis from epidermoid cancer that occurred in the left clavicle of a patient with a history of laryngeal cancer treated on April 2005 with extended hemilaryngectomy, neck dissection and chemoradiation therapy. On September 2008, he developed a left clavicular metastasis. The disease was initially well controlled by chemoradiotherapy but it recurred 17 months later. The optimal treatment plan was established by several multidisciplinary meetings and the patient subsequently underwent an en bloc resection of the left clavicle, first rib and all the other involved structures. Coverage of the thoracic defect was achieved using pectoralis major myocutaneous …
