Periacetabular osteotomy (PAO) is an effective joint-preserving procedure for developmental dysplasia of the hip. However, some patients report dissatisfaction after PAO. Because patient satisfaction is increasingly used as a health care quality metric, it is important to gain a better understanding of factors associated with patient satisfaction after PAO. The goal of this study was to investigate patient satisfaction among a cohort of Asian patients undergoing PAO. This study included 227 Asian patients who had undergone PAO at our institution between 1998 and 2016. The study participants completed a questionnaire assessing patient satisfaction, reasons for dissatisfaction, and postoperative Oxford Hip Score (OHS) and University of California, Los Angeles (UCLA), activity scale score. Based on their satisfaction levels, the participants were divided into 4 subgroups, and their demographic characteristics and postoperative patient-reported outcomes were compared. Of the 227 patients, 190 expressed satisfaction that correlated with OHS-pain, OHD-activities of daily living, and UCLA activity scale scores. Primary reasons for dissatisfaction after PAO were persistent pain (24 of 49, 49%), functional limitations (14 of 49, 29%), stiffness around the hip (4 of 49, 8%), unmet expectations (4 of 49, 8%), conversion to total hip arthroplasty (2 of 49, 4%), and complications (1 of 49, 2%). Multivariate analysis showed that preoperative Kellgren-Lawrence grades 1 and 3 were the significant predictive factors for satisfaction and dissatisfaction, respectively. The potential for lower patient satisfaction associated with Kellgren-Lawrence grade 3 because of persistent pain and functional limitations postoperatively suggests that consideration of preoperative severity of osteoarthritis could enhance patient satisfaction after PAO.

Up to 80% of Alzheimer's disease (AD) patients in nursing homes experiences chronic pain and 97% develops fluctuant neuropsychiatric symptoms (NPS). Agitation, associated with unrelieved pain, is managed through antipsychotics and may increase the risk of death. Evidence is accumulating in favor of analgesia for a safer, effective therapy of agitation. The Italian version of Mobilization-Observation-Behavior-Intensity-Dementia, I-MOBID2, recently validated in the Italian setting, shows: good scale content validity index (0.89), high construct validity (Spearman rank-order correlation Rho = 0.748), reliable internal consistency (Cronbach's α coefficient = 0.751), good-excellent inter-rater (intraclass correlation coefficient, ICC = 0.778) and test-retest (ICC = 0.902) reliability, and good inter-rater and test-retest agreement (Cohen's K = 0.744) with 5.8 min completion time. This study intends to identify the responsiveness of the I-MOBID2 based on COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) recommendations, assessing the a priori hypotheses of (1) the efficacy of painkillers administered to severe AD patients after proper pain assessment and (2) the effect of reduction of the Cohen-Mansfield Agitation Inventory (CMAI) score and of agitation rescue medications. This protocol is approved by Calabria Region Ethics Committee protocol No. 31/2017 and follows the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) guidelines.

Ovarian cancer is a female malignancy with high fatality-to-case ratio, which is due to late detection of cancer. Understanding the molecular mechanisms participating in these processes would facilitate design of therapeutic modalities and identification of novel tumor markers. Recent investigations have shown contribution of circular RNAs (circRNAs) in the evolution of ovarian cancer. These transcripts are produced through a back-splicing mechanism. The enclosed configuration of circRNAs protects them from degradation and potentiates them as biomarkers. Several circRNAs such as circMUC16, circRNA_MYLK, circRNA-UBAP2, circWHSC1, hsa_circ_0013958, circFGFR3, hsa_circRNA_102958 and circ_0072995 have been found to be up-regulated in this cancer, acting as oncogenes. On the other hand, circ-ITCH, circPLEKHM3, circ_100395, circ_0078607, circATRNL1, circHIPK3, circRHOBTB3, circEXOC6B, circ9119 and CDR1as are among down-regulated circRNAs in ovarian cancer. Expression levels of circCELSR1, circ_CELSR1, circATL2, circNRIP1, circTNPO3 and hsa_circ_0000714 have been shown to affect resistance of ovarian cancer cells to chemotherapy. Moreover, circ_100395, circFGFR3, circ_0000554, circCELSR1, circ-PTK2, circLNPEP, circ-CSPP1, circ_0000745, circ_100395 and circPLEKHM3 have been shown to regulate epithelial-mesenchymal transition and metastatic ability of ovarian cancer cells. In the current review, we explain the roles of circRNAs in the evolution and progression of ovarian cancer.

A 49-year-old Japanese man had a chief complaint of left hypochondrium pain, and a CT scan revealed a mass in the left retroperitoneal space. CT and MRI scans revealed a hemorrhagic component and surrounding fibrous tissues. FDG PET/CT images showed increased uptake in the peripheral rim of the mass, indicating a malignant tumor. The SUVmax was 7.6. We surgically resected the mass. The pathological examination confirmed the diagnosis of chronic expanding hematoma. It is difficult to differentiate CEH from malignant tumors on imaging; this should be recognized as a diagnostic pitfall.

Carbohydrates are one of the most abundant and important classes of biomolecules. The variety in their structures makes them valuable carriers that can improve the pharmaceutical phase, pharmacokinetics and pharmacodynamics of well-known drugs. D-galactose is a simple, naturally occurring monosaccharide sugar that has been extensively studied for use as a carrier and has proven to be valuable in this role. With the aim of validating the galactose-prodrug approach, we have investigated the galactosylated prodrugs ibuprofen, ketoprofen, flurbiprofen and indomethacin, which we have named IbuGAL, OkyGAL, FluGAL and IndoGAL, respectively. Their physicochemical profiles in terms of lipophilicity, solubility and chemical stability have been evaluated at different physiological pH values, as have human serum stability and serum protein binding. Ex vivo intestinal permeation experiments were performed to provide preliminary insights into the oral bioavailability of the galactosylated prodrugs. Finally, their anti-inflammatory, analgesic and ulcerogenic activities were investigated in vivo in mice after oral treatment. The present results, taken together with those of previous studies, undoubtedly validate the galactosylated prodrug strategy as a problem-solving technique that can overcome the disadvantages of NSAIDs.

Pre-existing chronic pain has been associated with severe postoperative pain. In this study, we sought to prospectively analyse the association between the duration of chronic low back pain and the intensity of acute postoperative pain after lumbar fusion surgery.

Radiofrequency (RF) treatment of the genicular nerves offers pain relief in patients suffering from chronic knee pain including persistent post-surgical knee pain (PPSP). We present the first case report of the development of complex regional pain syndrome (CRPS) in a chronic knee pain patient after an RF ablation of the genicular nerves that was successfully treated with dorsal root ganglion (DRG) stimulation.

: Coronavirus disease 2019 (COVID-19) is a new disease entity caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The main symptoms of infection at the onset of the pandemic include dyspnea, cough and high fever. Ear-nose-throat (ENT) symptoms are among the ones presented by patients in the course of infection. The aim of the study was to analyze the frequency of ENT symptoms and to assess their severity and duration in COVID-19 patients. : The study included 337 patients who had been infected with SARS-CoV-2, as confirmed by a PCR test. The study participants were >18 years old; the mean age was 43.98 years ± 13.47 SD. The convalescents completed a questionnaire that contained 26 questions, including 9 detailed questions related to ENT symptoms, such as sore throat, vertigo, dizziness, hearing disorders, olfactory disorders, taste disturbance, headache, cough and dyspnea. The severity of symptoms was assessed using a Visual Analogue Scale (VAS). : The most reported ENT symptoms were olfactory disorders, which occurred in 72% of patients. The second most frequent symptom was taste disturbance (68%), VAS = 6.79 ± 3.01. Vertigo and dizziness were reported by 34% of respondents (VAS = 4.01 ± 2.01). Tinnitus was observed in 15% of patients, VAS = 3.87 ± 1.98; 14% of the subjects reported hearing impairment (VAS = 3.81 ± 2.37). : Symptoms related to the sense of smell, taste and hearing are some of the most common symptoms in the course of COVID-19, which is important in the therapeutic and epidemiological management of patients. Delayed diagnosis and treatment of symptoms, especially those related to the hearing organ, may result in greater permanent damage.

To investigated the effects of sufentanil in combination with flurbiprofen axetil and dexmedetomidine for patient-controlled intravenous analgesia (PCIA) on patients after open gastrointestinal tumor surgery, and compared this combination with traditional PCIA with pure opioids or epidural analgesia (PCEA).

A 39-year-old woman presented to the Emergency Department with dysuria and persistent abdominal pain for several weeks. The pain increased with palpation. Physical examination was otherwise normal. Computerized tomography (CT) scan revealed a round structure of unknown origin against the caecum and terminal ilium suspect for a GIST tumor and a fluid-filled right uterine tube suggestive of pyosalpinx. The following day a laparoscopic surgery with removal of the pyosalpinx and complete right hemi-colon including the suspected lesion was performed and biopsies of the surrounding peritoneum, meso and ileum were taken. Immunohistochemical tests (CD117/DOG1) and molecular analysis (KIT/PDGFRA) ruled out GIST. SMA and desmin were also negative. β-catenin along with next generation sequencing which revealed a likely pathogenic mutation in exon 3 of the CTNNB1 gene, suggested a diagnosis of desmoid-type fibromatosis (DF). Biopsies of the lymph nodes were negative.
