Fibromyalgia: Could hyperbaric oxygen therapy make the difference? Our experience.

Fibromyalgia is a rare disease, difficult to diagnose and to treat. We think that hyperbaric oxygen therapy could improve its signs and symptoms although more evidences have to be accumulated.

Hyperbaric oxygen therapy in stage III C Kienböck disease: Time is bone.

Kienböck disease, also known as lunatomalacia, is a rare condition which can lead to progressive wrist pain and abnormal carpal motion. We present the case of a 30-year-old patient with Down syndrome who came to our observation for treatment of stage III C Kienböck disease. In September 2019, the patient reported wrist pain with limitation in movements and initially underwent conservative treatment without benefit. In October 2020, pain symptoms and difficult movements with reduced strength worsened and surgical treatment was proposed, but the patient and his family declined. Thereby the patient underwent conservative treatment with hyperbaric oxygen therapy (HBOT) 60 sessions, 100% oxygen at 2.5 absolute atmospheres (ATA), oxygen total time 60 min, once daily, five times per week. After 6 months, a positive clinical and radiological evolution were observed, with an improvement in the patterns of pain, motion, and strength and an almost complete involution of the process of aseptic necrosis of the semilunar. To the best of our knowledge, this is the first report of stage III C Kienböck's disease in Down's syndrome patient treated with HBOT.

Hyperbaric oxygen therapy as adjuvant therapy for odontogenic necrotizing myositis: A case report.

In a young man affected by skin soft tissue infections complicated with myositis, the use of hyperbaric oxygen treatment as an adjuvant therapy to surgical debridement and antibiotic therapy could improve management and prognosis.

Draft Genome Sequence and Biofilm Production of a Carbapenemase-Producing Klebsiella pneumoniae (KpR405) Sequence Type 405 Strain Isolated in Italy.

Rapid identification and characterization of multidrug-resistant Klebsiella pneumoniae strains is essential to diagnose severe infections in patients. In clinical routine practice, K. pneumoniae is frequently identified and characterized for outbreak investigation. Pulsed-field gel electrophoresis or multilocus sequence typing could be used, but, unfortunately, these methods are time-consuming, laborious, expensive, and do not provide any information about the presence of resistance and virulence genes. In recent years, the decreasing cost of next-generation sequencing and its easy use have led to it being considered a useful method, not only for outbreak surveillance but also for rapid identification and evaluation, in a single step, of virulence factors and resistance genes. Carbapenem-resistant strains of K. pneumoniae have become endemic in Italy, and in these strains the ability to form biofilms, communities of bacteria fixed in an extracellular matrix, can defend the pathogen from the host immune response as well as from antibiotics, improving its persistence in epithelial tissues and on medical device surfaces.

An Update of the Evolving Epidemic of blaKPC Carrying Klebsiella pneumoniae in Sicily, Italy, 2014: Emergence of Multiple Non-ST258 Clones.

BACKGROUND: In Italy, Klebsiella pneumoniae carbapenemase producing K. pneumoniae (KPC-Kp) strains are highly endemic and KPC producing CC258 is reported as the widely predominating clone. In Palermo, Italy, previous reports have confirmed this pattern. However, recent preliminary findings suggest that an epidemiological change is likely ongoing towards a polyclonal KPC-Kp spread. Here we present the results of molecular typing of 94 carbapenem non susceptible K. pneumoniae isolates detected during 2014 in the three different hospitals in Palermo, Italy. METHODS AND RESULTS: Ninety-four consecutive, non replicate carbapenem non susceptible isolates were identified in the three largest acute general hospitals in Palermo, Italy, in the six-month period March-August 2014. They were characterized by PCR for ß-lactam, aminoglycoside and plasmid mediated fluoroquinolone resistance genetic determinants. The mgrB gene of the colistin resistant isolates was amplified and sequenced. Clonality was assessed by pulsed field gel electrophoresis and multilocus sequence typing. Eight non-CC258 sequence types (STs) were identified accounting for 60% of isolates. In particular, ST307 and ST273 accounted for 29% and 18% of isolates. CC258 isolates were more frequently susceptible to gentamicin and non-CC258 isolates to amikacin. Colistin non susceptibility was found in 42% of isolates. Modifications of mgrB were found in 32 isolates. CONCLUSIONS: Concurrent clonal expansion of some STs and lateral transmission of genetic resistance determinants are likely producing a thorough change of the KPC-Kp epidemiology in Palermo, Italy. In our setting mgrB inactivation proved to substantially contribute to colistin resistance. Our findings suggest the need to continuously monitor the KPC-Kp epidemiology and to assess by a nationwide survey the possible shifting towards a polyclonal epidemic.

Co-colonization with carbapenem-resistant Klebsiella pneumoniae and Acinetobacter baumannii in intensive care unit patients.

OBJECTIVES: This investigation was conducted to study co-colonization by carbapenem-resistant Klebsiella pneumoniae carbapenemase-producing K. pneumoniae (KPC-Kp) and Acinetobacter baumannii (CRAB) in intensive care unit (ICU) patients in Palermo, Sicily, a geographic area where both organisms are endemic in the healthcare setting. Risk factors at admission and during ICU stay and outcomes were also evaluated. METHODS: All patients colonized by KPC-Kp, or CRAB, or both in 2 ICUs of a large general hospital during the period October 2011-March 2012 were enrolled. Demographics and clinical data were collected. Resistance determinants and clonality of the 2 organisms were characterized by molecular methods. RESULTS: Seventy-five of 391 patients (19.2%) proved to be colonized by KPC-Kp, CRAB, or both: 30 (40%) were co-colonized and 44 (58.7%) were mono-colonized by CRAB and 1 by KPC-Kp. Younger age, major trauma, and length of stay were positively associated with co-colonization. However, no significant differences were detected between co-colonized and non co-colonized patients in infection and ICU mortality rates and length of stay after the first isolation. Both organisms proved to be circulating in a clonal way. CONCLUSIONS: In our setting, co-colonization by KPC-Kp and CRAB disproportionately affected young trauma patients with those with a prolonged ICU stay.

Epidemiology and clonality of carbapenem-resistant Acinetobacter baumannii from an intensive care unit in Palermo, Italy.

BACKGROUND: Multidrug-resistant Acinetobacter baumannii, initially considered as having a poor clinical relevance, is frequently isolated from infection cases in intensive care units. We describe the epidemiology of carbapenem resistant A. baumannii (CRAB) in a general ICU in Palermo, Italy, from October 2010 to March 2011. FINDINGS: 58 of 61 isolates exhibited MICs for meropenem or imipenem ≥16 mg/L. Forty-nine carried blaOXA-23 and two blaOXA-58 genes.Five subtype clusters were detected by rep-PCR. Clusters D and E included 10 isolates that tested negative for the carbapenem resistance genes. MLST attributed all isolates, but two, with sequence type (ST)2, whereas the two remaining isolates with ST78.The respiratory tract was the most common site of infection (26 out of 36 cases. 72.2%). A high infection related mortality rate was observed (18 out of 35 patients, 51.4%). Nineteen patients tested positive for other multidrug resistant organisms in addition to CRAB. In eight cases isolates belonging to distinct subtype clusters and/or with distinct carbapenemase profiles were identified. CONCLUSIONS: Carbapenem resistance was prominently driven by the dissemination of CRAB isolates belonging to ST2, carrying the carbapenemase gene blaOXA-23. The colonization/infection of some patients by multiple strains is suggestive of an endemic circulation of CRAB.

A Fatal Bloodstream Infection by Staphylococcus pettenkoferi in an Intensive Care Unit Patient.

Coagulase negative staphylococci are increasingly recognized as leading pathogens in bacteremia, with incidence peaking in intensive care units. Interpretation of blood cultures that are positive for CoNS is often doubtful. We describe a fatal case of bacteremia by a newly recognized species of CoNS, Staphylococcus pettenkoferi, in an ICU patient.
