Objective: To examine the effect of pre-operative physiotherapy before hip arthroplasty in patients with end-stage hip osteoarthritis. Design: A prospective randomized controlled study. Setting: Physical medicine and rehabilitation and orthopaedic departments of Policlinico Gemelli of Rome. Subjects: Twenty-three patients randomized in study and control groups. Intervention: The study group took part in an educational and physiotherapy programme one month before surgery. Both groups took part in the same inpatient rehabilitation programme after surgery. Main outcome measures: Both groups were evaluated one month (T0) and the day before arthroplasty (T1), after 15 days (T2), four weeks (T3) and three months (T4) post surgery, using the Barthel Index, the Short Form-36 (SF-36), the Western Ontario and McMaster Osteoarthritis Index (WOMAC), the Hip Harris Score (HHS), visual analogue scale (VAS), the British Medical Research Council (BMRC) measures of hip abductor and quadriceps strength and range of hip abduction and external rotation. Results: There were no significant differences between groups with regard to the Barthel Index, SF-36, WOMAC and HHS at T4. The study group presented significant improvements of the SF-36 physical composite score at T1. The hip external rotation was significantly higher in the study group at each evaluation and the visual analogue scale values were lower at T1, T3 and T4. Conclusion: Pre-operative physiotherapy in patients undergoing hip arthroplasty does not improve impairment and health-related quality of life after intervention. Physiotherapy and educational therapy may be useful for end-stage osteoarthritis.

Background Tactile maneuvers stimulating spontaneous respiratory activity in preterm infants are recommended since birth, but data on how and how often these maneuvers are applied in clinical practice are unknown. In the last years, most preterm newborns with respiratory failure are preferentially managed with non-invasive respiratory support and by stimulating spontaneous respiratory activity from the delivery room and in neonatal intensive care unit (NICU), in order to avoid the risks of intubation and prolonged mechanical ventilation. Methods Preterm infants with gestational age < 31 weeks not intubated in the delivery room and requiring non-invasive respiratory support at birth will be eligible for the study. They will be randomized and allocated to one of two treatment groups: (1) the study group infants will be subject to the technique of respiratory facilitation within the first 24 h of life, according to the reflex stimulations, by the physiotherapist. The newborn is placed in supine decubitus and a slight digital pressure is exerted on a hemithorax. The respiratory facilitation technique will be performed for about three minutes and repeated for a total of 4/6 times in sequence, three times a day until spontaneous respiratory activity is achieved; thus, no respiratory support is required; (2) the control group infants will take part exclusively in the individualized postural care program. They will perform the technique of respiratory facilitation and autogenous drainage. Objective To evaluate the efficacy of early respiratory physiotherapy in reducing the incidence of intubation and mechanical ventilation in the first week of life (primary outcome). Discussion The technique of respiratory facilitation is based on reflex stimulations, applied early to preterm infant. Slight digital pressure is exerted on a “trigger point” of each hemithorax, to stimulate the respiratory activity with subsequent increase of the ipsilateral pulmonary minute ventilation and to facilitate the contralateral pulmonary expansion. This mechanism will determine the concatenation of input to all anatomical structures in relation to the area being treated, to promote spontaneous respiratory activity and reducing work of breathing, avoiding or minimizing the use of invasive respiratory support.

Mesotherapy (local intradermal therapy, LIT) is a technique used to slowly spread drugs in tissues underlying the site of injection to prolong the pharmacological effect with respect to intramuscular injection. Recommendations for proper medical use of this technique have been made for pain medicine and rehabilitation, chronic venous disease, sport medicine, musculoskeletal disorders, several dermatological conditions, skin ageing, and immune-prophylaxis. Although mesotherapy is considered a valid technique, unresolved questions remain, which should be answered to standardize methodology and dosing regimen as well as to define the right indications in clinical practice. New randomized controlled trials are needed to test single products (dose, frequency of administration, efficacy and safety). Even infiltration of substances for dermo-cosmetic purposes must be guided by safety and efficacy tests before being proposed by mesotherapy. In this article, we put forth a preclinical and clinical research plan and a health technology assessment as a call to action by doctors, researchers and scientific societies to aid national health authorities in considering mesotherapy for prevention, treatment and rehabilitation paths.

Background: Tactile stimulation manoeuvres stimulate spontaneous breathing in preterm newborns. The aim of this study is to evaluate the effect of early respiratory physiotherapy on the need for mechanical ventilation during the first week of life in preterm infants with respiratory failure. Methods: This is a monocentric, randomised controlled trial. Preterm infants (gestational age ≤ 30 weeks) not intubated in the delivery room and requiring non-invasive respiratory support at birth were eligible for the study. The intervention group received early respiratory physiotherapy, while the control group received only a daily physiotherapy program (i.e., modifying the infant’s posture in accordance with the patient’s needs). Results: between October 2019 and March 2021, 133 preterm infants were studied, 68 infants in the study group and 65 in routine care. The study group showed a reduction in the need for mechanical ventilation (not statistically significant) and a statistically significant reduction in hemodynamically significant patent ductus arteriosus with respect to the control group (19/68 (28%) vs. 35/65 (54%), respectively, p = 0.03). Conclusions: early respiratory physiotherapy in preterm infants requiring non-invasive respiratory support at birth is safe and has proven to be protective against haemodynamically significant PDA.

Objective: To determine the short-term effects of local microwave hyperthermia on pain and function in patients with mild to moderate idiopathic carpal tunnel syndrome. Design: Double-blind randomized sham-controlled trial. Setting: Outpatient clinic of the Department of Physical Medicine and Rehabilitation, University Hospital. Participants: Twenty-two patients with idiopathic carpal tunnel syndrome, 12 of whom had bilateral involvement, for a total of 34 wrists, divided into two groups: a hyperthermia active treatment group (number of wrists = 17) and a sham-controlled group (number of wrists = 17). Intervention: Six sessions, two per week, of either hyperthermia or sham treatment were provided over a period of three weeks. Main measures: Visual analogue scale, Levine–Boston Self-Assessment Questionnaire (part I: evaluation of pain intensity; part II: evaluation of functional status) and neurophysiological assessments, were determined at baseline and at the end of the treatment. Results: The hyperthermia group experienced a significant improvement in pain (visual analogue scale: P = 0.002; Levine–Boston part I: P < 0.0001) and functional status (Levine–Boston part II: P = 0.002) relative to baseline. No improvements in pain intensity or functionality were observed in the sham-treated group. Changes in pain severity between baseline and the end of treatment were larger in the hyperthermia group than in the sham-controlled group (Δ visual analogue scale P = 0.004; Δ Levine–Boston part I: P = 0.009). No differences either intra or between groups were observed for median nerve conduction velocity. Conclusion: Hyperthermia provides short-term improvements in pain and function in patients with mild to moderate carpal tunnel syndrome.

Objective : To assess the effectiveness of conservative therapy in carpal tunnel syndrome. Data sources : A computer-aided search of MEDLINE and the Cochrane Collaboration was conducted for randomized controlled trials (RCTs) from January 1985 to May 2006. Review methods : RCTs were included if: (1) the patients, with clinically and electrophysiologically confirmed carpal tunnel syndrome, had not previously undergone surgical release, (2) the efficacy of one or more conservative treatment options was evaluated, (3) the study was designed as a randomized controlled trial. Two reviewers independently selected the studies and performed data extraction using a standardized form. In order to assess the methodological quality, the criteria list of the Cochrane Back Review Group for systematic reviews was applied. The different treatment methods were grouped (local injections, oral therapies, physical therapies, therapeutic exercises and splints). Results : Thirty-three RCTs were included in the review. The studies were analysed to determine the strength of the available evidence for the efficacy of the treatment. Our review shows that: (1) locally injected steroids produce a significant but temporary improvement, (2) vitamin B6 is ineffective, (3) steroids are better than non-steroidal anti-inflammatory drugs (NSAIDs) and diuretics, but they can produce side-effects, (4) ultrasound is effective while laser therapy shows variable results, (5) exercise therapy is not effective, (6) splints are effective, especially if used full-time. Conclusion : There is: (1) strong evidence (level 1) on efficacy of local and oral steroids; (2) moderate evidence (level 2) that vitamin B6 is ineffective and splints are effective and (3) limited or conflicting evidence (level 3) that NSAIDs, diuretics, yoga, laser and ultrasound are effective whereas exercise therapy and botulinum toxin B injection are ineffective.

Background Findings from the T.O.S.CA. Registry recently reported that patients with concomitant chronic heart failure (CHF) and impairment of insulin axis (either insulin resistance—IR or diabetes mellitus—T2D) display increased morbidity and mortality. However, little information is available on the relative impact of IR and T2D on cardiac structure and function, cardiopulmonary performance, and their longitudinal changes in CHF. Methods Patients enrolled in the T.O.S.CA. Registry performed echocardiography and cardiopulmonary exercise test at baseline and at a patient-average follow-up of 36 months. Patients were divided into three groups based on the degree of insulin impairment: euglycemic without IR (EU), euglycemic with IR (IR), and T2D. Results Compared with EU and IR, T2D was associated with increased filling pressures (E/e′ratio: 15.9 ± 8.9, 12.0 ± 6.5, and 14.5 ± 8.1 respectively, p < 0.01) and worse right ventricular(RV)-arterial uncoupling (RVAUC) (TAPSE/PASP ratio 0.52 ± 0.2, 0.6 ± 0.3, and 0.6 ± 0.3 in T2D, EU and IR, respectively, p < 0.05). Likewise, impairment in peak oxygen consumption (peak VO 2 ) in TD2 vs EU and IR patients was recorded (respectively, 15.8 ± 3.8 ml/Kg/min, 18.4 ± 4.3 ml/Kg/min and 16.5 ± 4.3 ml/Kg/min, p < 0.003). Longitudinal data demonstrated higher deterioration of RVAUC, RV dimension, and peak VO 2 in the T2D group (+ 13% increase in RV dimension, − 21% decline in TAPSE/PAPS ratio and − 20% decrease in peak VO 2 ). Conclusion The higher risk of death and CV hospitalizations exhibited by HF-T2D patients in the T.O.S.CA. Registry is associated with progressive RV ventricular dysfunction and exercise impairment when compared to euglycemic CHF patients, supporting the pivotal importance of hyperglycaemia and right chambers in HF prognosis.

The role of sexual transmission in the diffusion of HCV infection, was studied through the seroprevalence of anti-HCV antibodies in the heterosexual habitual partners of 83 anti-HCV positive subjects. The index cases were represented by 10 dialysed subjects, 31 patients with chronic liver disease and 42 healthy carriers. Seroprevalence of anti-HCV positivity reported in partners was 8.43%, with a higher rate in cohabitants of patients with chronic liver disease (16.12% vs 4.76% of carriers); no case was found among partners of dialysed subjects. Laboratory and ultransonograph signs of chronic hepatitis were reported in 3 cases (3.61%). Control on 70% of the cohabitants' relatives, was negative for HCV infections. These data suggest a possible sexual transmission of HCV infection, even if its prevalence resulted modest, undoubtedly lower than in other disease sexually transmitted.

The mechanisms producing fast variability of the \\(\\gamma\\)-ray emission in active galactic nuclei are under debate. The MAGIC telescopes detected a fast very high energy (VHE, E\\(>100\\) GeV) \\(\\gamma\\)-ray flare from BL Lacertae on 2015 June 15. The flare had a maximum flux of \\((1.5\\pm 0.3)\\times 10^{-10}\\) photons cm\\(^{-2}\\) s\\(^{-1}\\) and halving time of \\(26\\pm8\\) minutes. The MAGIC observations were triggered by a high state in the optical and high energy (HE, E\\(>100\\) MeV) \\(\\gamma\\)-ray bands. In this paper we present the MAGIC VHE \\(\\gamma\\)-ray data together with multiwavelength data from radio, optical, X-rays, and HE \\(\\gamma\\) rays from 2015 May 1 to July 31. Well-sampled multiwavelength data allow us to study the variability in detail and compare it to the other epochs when fast VHE \\(\\gamma\\)-ray flares have been detected from this source. Interestingly, we find that the behaviour in radio, optical, X-rays and HE \\(\\gamma\\)-rays is very similar to two other observed VHE \\(\\gamma\\)-ray flares. In particular, also during this flare there was an indication of rotation of the optical polarization angle and of activity at the 43\\,GHz core. These repeating patterns indicate a connection between the three events. We also test modelling of the spectral energy distribution, based on constraints from the light curves and VLBA observations, with two different geometrical setups of two-zone inverse Compton models. In addition we model the \\(\\gamma\\)-ray data with the star-jet interaction model. We find that all of the tested emission models are compatible with the fast VHE \\(\\gamma\\)-ray flare, but all have some tension with the multiwavelength observations.
