BackgroundHomeopathic medicine is a branch of integrative medicine that has been gaining increasing popularity. However, its clinical application remains controversial.To improve the understanding of homeopathy, observational studies-which monitor the effects of homeopathy in real-life clinical settings-are a helpful adjunct to randomized controlled trials.The goal of this controlled observational study was to investigate the role of the homeopathic medicine in preventing respiratory tract infections (RTIs).MethodsThis retrospective analysis of patients’ medical records focused on a single centre from 2002 to 2011, and examined 459 patients, out of whom 248 were treated with homeopathic medicine (specific extract of duck liver and heart) and 211 were not treated. All patients were followed-up for at least 1 year, and up to a maximum of 10 years.ResultsA significant reduction in the frequency of onset of RTIs was found in both the homeopathic medicine and untreated groups. The reduction in the mean number of RTI episodes during the period of observation vs. the year before inclusion in the study was significantly greater in the homeopathic-treated group than in untreated patients (-4.76 ± 1.45 vs. -3.36 ± 1.30; p = 0.001).

Acute rhinosinusitis (ARS) is one of the most common reasons for physician visits and for significant school absenteeism, although precise data on its prevalence and incidence are still lacking. RS is defined as acute if there are symptoms lasting <12 wk with complete resolution. Superinfection by bacteria following a viral infection is the most important mechanism of ARS. Diagnosis of ARS should be made on clinical grounds alone. Typically, acute bacterial RS is self-limited and goes through spontaneous recovery within 4 wk. Recognizing the occurrence of bacterial superinfections of the sinuses during a common viral respiratory infection is fundamental to making the decision to start an appropriate antibiotic treatment. Topical treatments such as saline irrigation, nasal decongestants, steroids, antihistamines, and fungicides are all in widespread pediatric use, but analyzing the literature gives poor evidence of efficacy, except for topical steroids. RS is a multifactorial condition that poses a diagnostic and management challenge to infectivologist and ear-nose-throat specialists as well as to pediatricians.

Nosocomial or hospital acquired pneumonia (HAP) is an illness contracted during a hospital stay, generally with onset 48 hours or more after admission to hospital, or within 14 days of discharge from hospital. HAP is divided into subgroups: Ventilator-associated pneumonia (VAP), accounting for 86% of hospital acquired pneumonia, and stroke-associated pneumonia (SAP). The incidence of SAP in neurological intensive care units (NICUs) is 4.1-56.6%, in medical intensive care units (MICUs) it is 17-50%, in stroke units it is 3.9-44% and in rehabilitation it is 3.2-11%, whereas in intensive rehabilitation following severe cranial trauma, the reported incidence of HAP is between 3.9 and 12% of cases. The aim of this study is to evaluate the cases of HAP occurring in a continuous series of patients with severe acquired brain injury (sABI) admitted to intensive rehabilitation units. The data collected can help evaluate the growing complexity of early rehabilitation of these patients, starting from how lung infections interfere with hospital stays and rehabilitation outcomes. This prospective observational cohort study evaluates, from 01/01/2015 to 31/12/2015, for patients with sABI on first admission to intensive neurological rehabilitation, the frequency of HAP and its impact on patient outcomes and complexity of care. A total of 61 patients were enrolled: 39 males and 22 females, average age 59.5 years (17-88 yrs, SD 3.53), coming from critical care (n=52), medical units (n=5), neurosurgery (n=3) and surgical units (n=1). The aetiology of hospital admission was haemorrhagic in 36% of cases, traumatic in 36%, anoxic in 13.1%, infectious in 6.5%, ischaemic in 4.9%, and other causes in 3.2%. Among the patients, 93.44% had received antibiotic therapy in their unit of provenance, and in 61.27% of cases a multidrug resistant (MDR) bacterium was isolated. On enrolment, 26 patients presented respiratory insufficiency, 29 subjects were in oxygen therapy, and 4 under invasive mechanical ventilation. There were 54 tracheostomized patients, 33 patients with percutaneous endoscopic gastrostomy (PEG) tubes, and 23 with nasogastric (NG) tubes. In 2015, among these subjects admitted to neurological rehabilitation, the incidence of HAP was 13.1%. For these 8 pneumonia cases, it was possible to isolate the bacterium in 62.5% of cases, and the detected microorganisms were K. pneumoniae (n=2), P. aeruginosa (n=1), P. mirabilis (n=1), S. maltophilia (n=1), E. cloacae + MRSCoN (n=1). Compared to the literature data, the results of the first year of monitoring show a slight increase in HAP cases (13.1%) in severe brain injury patients on first admission to neurological rehabilitation. These preliminary results need to be further confirmed and monitored over time. The findings moreover confirm the criticality and complexity of care for these patients admitted to neurological rehabilitation units.
