BACKGROUND Nonunion of a rib fracture can cause chronic pain, and pharmacological pain management may lead to medication dependence. This report describes a 54-year-old man with a chronic cough and painful nonunion fracture of the left posterior 8th rib, managed with minimally invasive surgery and a rib splint. CASE REPORT A 54-year-old man presented with chronic cough-induced left chest wall pain. Three-dimensional chest computed tomography (CT) scan showed a nonunion of a fracture of the left posterior 8th rib. After medical management failure, we proposed a surgical approach with the aim to remove the tissue comprising the nonunion, release the nerve, and stabilize the bone stumps. To avoid the adverse effects of a large incision, we designed a minimally invasive strategy based on ultrasound fracture localization and the use of an intramedullary splint. The pain disappeared immediately after surgery. The patient was discharged in 24 hours. At 6-week follow-up, he was still asymptomatic, and a new CT scan reconfirmed the correct splint position. From the immediate postoperative evaluation until the last follow-up visit, he consistently reported full satisfaction. CONCLUSIONS This report has highlighted the challenges of management of chronic pain in nonunion of a rib fracture, and has described the use of a minimally invasive surgical approach. In this single case, our tailored surgical strategy achieved definitive success in pain management, minimizing postoperative complications/adverse effects and avoiding the addition of pain medications despite a 24-hour hospital stay. Our goal is to share an alternative solution for colleagues facing similar cases.

Chronic cough is a common disorder lasting more than 8 weeks and affecting all age groups. The evidence supporting the role of neutrophils in chronic cough pathology is based on many patients with chronic cough developing airway neutrophilia. How neutrophils influence the development of chronic cough is unknown. However, they are likely involved in multiple aspects of cough etiology, including promoting airway inflammation, airway remodeling, hyper-responsiveness, local neurogenic inflammation, and other possible mechanisms. Neutrophilic airway inflammation is also associated with refractory cough, poor control of underlying diseases (e.g., asthma), and insensitivity to cough suppressant therapy. The potential for targeting neutrophils in chronic cough needs exploration, including developing new drugs targeting one or more neutrophil-mediated pathways or altering the neutrophil phenotype to alleviate chronic cough. How the airway microbiome differs, plays a role, and interacts with neutrophils in different cough etiologies is poorly understood. Future studies should focus on understanding the relationship between the airway microbiome and neutrophils.

BACKGROUND: Chronic cough has been associated with reduced health-related quality of life, negative impacts on sleep, work, and other daily activities, and increased use of health care resources. Little is known about the prevalence of chronic cough in Italy. In the present study we sought to estimate the prevalence of chronic cough in Italy, describe sociodemographic and clinical characteristics associated with chronic cough, and characterize the impact of chronic cough on overall health and wellness, work and other daily activities, and health care resource use.
METHODS: We conducted a cross-sectional study to collect sociodemographic and health-related data from Italian residents who participated in the 2020 National Health and Wellness Survey (N = 10,026). To assess the characteristics and burden of chronic cough, adults who indicated that they had experienced chronic cough during the prior 12 months were compared with propensity score-matched controls without chronic cough.
RESULTS: The estimated weighted lifetime and 12-month prevalence of chronic cough were estimated as 9.2% and 6.3%, respectively. Compared with matched controls, respondents with chronic cough had significantly lower measures of overall physical and mental health (P < .001 for both comparisons), and significantly higher rates of anxiety, depression, and sleep disorders (P < .001 for all comparisons). Chronic cough was significantly associated with higher rates of impairment of work and other activities (P < .001 for all comparisons) in the past 7 days, any-cause emergency department visits and hospitalizations in the prior 6 months (P < .001 for both comparisons), and more visits to general and specialist health care providers (P < .001 for both comparisons) in the prior 6 months.
CONCLUSIONS: In Italy, chronic cough affects an estimated 3.3 million adults annually and represents a significant burden to individuals and the health care system.
CONCLUSIONS: Little is known about the prevalence of chronic cough in Italy. We found that, in Italy chronic cough represents a significant burden to individuals and the health care system, affecting an estimated 3.3 million adults annually.

Background and objective: Chronic cough (CC) is a prevalent yet underexplored medical condition, with limited real-world data regarding its healthcare burden. This study investigates the epidemiology, associated comorbidities, and healthcare service utilization among patients with CC. Methods: In this retrospective cohort study, adult patients with at least 3 physician diagnoses of cough over a period spanning a minimum of 8 weeks and a maximum of 12 months anytime between 2009 and 2018, were defined as patients with CC (PwCC). The reference group were adults without cough matched in a 1:1 ratio for age, sex, and place of residence. Results: The study included 91,757 PwCC, reflecting a prevalence of 5.5%. Of those, 59,296 patients (mean [SD] age, 53.9 [16.8] years; 59.6% females) were first diagnosed with CC during the study period, representing a 10-year incidence rate of 3.26% (95%CI: 3.24-3.29%). Diseases associated with the highest OR for CC included lung cancer (OR = 3.32; 95%CI: 2.90-4.25), whooping cough (OR = 3.04; 95%CI: 2.70-3.60), and respiratory infections (OR = 2.81; 95%CI: 2.74-2.88). Furthermore, PwCC demonstrated increased healthcare service utilization, leading to a higher adjusted annual estimated mean cost (USD 4038 vs. USD 1833, p < 0.001). Conclusions: Chronic cough emerges as a relatively prevalent complaint within community care, exerting a considerable economic burden. This study underscores the need for heightened awareness, comprehensive management strategies, and resource allocation to address the multifaceted challenges associated with chronic cough.

People with chronic cough (a cough lasting more than 8 weeks) are often referred to different specialists and undergo numerous diagnostic tests, but clear guidance is lacking. This work summarizes a consensus (an agreement) among medical specialists who are involved in managing people with chronic cough: primary care physicians (family doctors), pulmonologists (doctors who specialize in lung conditions), allergists (medical professionals specializing in allergies) and ear, nose and throat (ENT) specialists. They discussed how to perform a basic assessment of people with chronic cough in primary care (day-to-day healthcare given by a general practitioner or family doctor) and how to refer them to different specialists based on clinical findings or test results.

UNASSIGNED: Postoperative complications may occur after major lung surgery for non-small cell lung cancer (NSCLC), with a high rate of morbidity and mortality. The main objective of this study was to assess the relevance of preoperative Leicester Cough Questionnaire (LCQ) to predict postoperative complications after major lung resection for any indication.
UNASSIGNED: This was a retrospective cohort study conducted in the Thoracic Surgery Department of Rouen University Hospital from November 21st, 2022, to June 2nd, 2023. Patients aged ≥18 years who underwent major lung resection for any indications and filled an LCQ self-questionnaire were included.
UNASSIGNED: Seventy-one patients were eligible for our study. One patient was lost to follow-up upon hospital discharge. Nineteen (27.1%) postoperative complications of grade ≥2 according to the Clavien-Dindo classification were observed. The mean LCQ total score was 18.11±2.56. The area under the receiver operating characteristic (ROC) curve for the LCQ result to predict postoperative complications of grade ≥2 within 30 days following the surgical intervention was 0.60 [95% confidence interval (CI): 0.45, 0.75].
UNASSIGNED: This study failed to demonstrate the relevance of a preoperative LCQ to predict postoperative complications after major lung surgery. However, the statistical precision of this study was insufficient to show a moderate predictive performance. Further studies conducted in larger populations are needed.

UNASSIGNED: Chronic cough (CC) affects about 10% of adults, but opioid use in CC is not well understood.
UNASSIGNED: To determine the use of opioid-containing cough suppressant (OCCS) prescriptions in patients with CC using electronic health records.
UNASSIGNED: Retrospective cohort study.
UNASSIGNED: Through retrospective analysis of Midwestern U.S. electronic health records, diagnoses, prescriptions, and natural language processing identified CC - at least three medical encounters with cough, with 56-120 days between first and last encounter - and a \'non-chronic cohort\'. Student\'s t-test, Pearson\'s chi-square, and zero-inflated Poisson models were used.
UNASSIGNED: About 20% of 23,210 patients with CC were prescribed OCCS; odds of an OCCS prescription were twice as great in CC. In CC, OCCS drugs were ordered in 38% with Medicaid insurance and 15% with commercial insurance.
UNASSIGNED: Findings identify an important role for opioids in CC, and opportunity to learn more about the drugs\' effectiveness.

BACKGROUND: Chronic cough (persisting for ≥ 8 weeks) is a common disorder that includes refractory chronic cough (RCC; cough that persists despite treatment of underlying disease) and unexplained chronic cough (UCC; cough with no identifiable cause). We evaluated self-reported health-related quality of life (HR-QoL) and work/activity impairment associated with RCC/UCC in Canada.
METHODS: Our exploratory study included Canadians in the Leger Opinion Panel with RCC or UCC. Key entry criteria were ≥ 18 years of age, cough for ≥ 8 weeks, not currently smoking/quit ≥ 1 year ago, no serious respiratory disease or lung cancer, and not taking angiotensin-converting enzyme inhibitors. Respondents completed a 30-min online survey with general and cough-specific HR-QoL questionnaires, including the EuroQol (EQ) visual analogue scale (VAS), EQ-5-dimension 5-level (EQ-5D-5L), cough severity VAS, Leicester Cough Questionnaire (LCQ), and Work Productivity and Activity Impairment-Specific Health Problem (WPAI-SPH).
RESULTS: Of 49,076 individuals who completed the chronic cough screening questionnaire (July 30-September 1, 2021), 1,620 (3.3%) met entry criteria for RCC/UCC and 1,046 (2.1%) completed the survey. The mean age of respondents was 45 years and 61% were female. Respondents reported impairments in global HR-QoL (EQ-VAS 73.8, 61% with anxiety/depression on the EQ-5D-5L) and cough-specific HR-QoL (mean cough severity VAS score 29.7, LCQ index 15.2). Work and non-work activities were reduced by 34% and 30%, respectively, on the WPAI-SPH.
CONCLUSIONS: RCC/UCC is prevalent in Canada and associated with impaired HR-QoL, particularly in mental health domains. Additional support and management options may be required to fully address this burden.

BACKGROUND: Post-reflux swallow-induced peristaltic wave index (PSPWI) and mean nocturnal baseline impedance (MNBI) are novel parameters reflect esophageal clearance capacity and mucosal integrity. They hold potential in aiding the recognition of gastroesophageal reflux-induced chronic cough (GERC). Our study aims to investigate their diagnostic value in GERC.
METHODS: This study included patients suspected GERC. General information and relevant laboratory examinations were collected, and final diagnosis were determined following guidelines for chronic cough. The parameters of multichannel intraluminal impedance-pH monitoring (MII-pH) in patients were analyzed and compared to explore their diagnostic value in GERC.
RESULTS: A total of 186 patients were enrolled in this study. The diagnostic value of PSPWI for GERC was significant, with the area under the working curve (AUC) of 0.757 and a cutoff value of 39.4%, which was not statistically different from that of acid exposure time (AET) (p > 0.05). The combined diagnostic value of AET > 4.4% and PSPWI < 39.4% was superior to using AET > 4.4% alone (p < 0.05). Additionally, MNBI and distal MNBI also contributed to the diagnosis of GERC, with AUC values of 0.639 and 0.624, respectively. AET > 4.4% or PSPWI < 39.4% is associated with a 44% reduction in missed diagnoses of non-acid GERC compared to AET > 6.0% or symptom association probability (SAP) ≥ 95%, and may be more favorable for identifying GERC.
CONCLUSIONS: The diagnostic value of PSPWI for GERC is comparable to that of AET. Combining PSPWI < 39.4% or AET > 4.4% can improve the diagnostic efficiency by reducing the risk of missed diagnoses in cases where non-acid reflux is predominant. Distal MNBI and MNBI can serve as secondary reference indices in the diagnosis of GERC.
