Efficacy of botanical lozenges in the treatment of chronic pharyngitis: a randomized controlled trial.

Background: In clinical practice, antibiotics and/or inhaled or oral hormone preparations are the first line of treatment for chronic pharyngitis. However, this therapeutic regimen is not satisfactory enough. At present, medicinal plants as dietary supplements or functional foods are widely recognized for the treatment and prevention of different diseases. Purpose: This study aimed to evaluate the efficacy of the botanical lozenge made from several medicinal plant extracts in the treatment of chronic pharyngitis and its effects on patients' illness perception and adherence to treatment. Methods: Patients with chronic pharyngitis were randomly assigned to the experimental group (n = 52) or the control group (n = 51). Patients were given botanical lozenges prepared from the extracts of medicinal plants such as Siraitia grosvenorii (Swingle) C. Jeffrey ex A.M.Lu and Zhi Y. Zhang [Cucurbitaceae; Siraitiae fructus], Lonicera japonica Thunb [Caprifoliaceae; Lonicerae japonicae flos], Platycodon grandiflorus (Jacq.) A. DC [Campanulaceae; Platycodon radix], and Glycyrrhiza uralensis Fisch. ex DC [Fabaceae; Glycyrrhizae radix et rhizoma] or placebos made of starch for 15 days. The improvement of pharyngeal symptoms and signs, illness perception, and adherence to treatment were evaluated at the end of the intervention. Results: The total score of pharyngeal symptoms of patients in the experimental group (3.33 ± 2.33) was significantly lower than that in the control group (5.20 ± 2.93) (p < 0.01). In comparison to the control group (3.43 ± 1.43), the total pharyngeal signs score of patients in the experimental group (2.69 ± 1.59) was considerably lower (p < 0.01). The improvement rates of pharyngeal itching, dry throat, pharyngeal foreign body sensation, aggravation due to excessive speaking, and congestion of pharyngeal mucosa in the experimental group were 73.81%, 67.50%, 67.57%, 65.22% and 44%, respectively, which were significantly higher than those in the control group (p < 0.05). In addition, patients taking botanical lozenges had better illness perception and adherence to treatment than those taking placebos (p < 0.05). Patients with low adherence to treatment showed less personal control, concerns, and understanding of chronic pharyngitis (p < 0.05). Conclusion: Botanical lozenges not only aided patients in recovering from chronic pharyngitis but also improved their positive perceptions of the disease, which helped them adhere to their treatment regimen.

Role of Polyunsaturated Fatty Acids (PUFAs) and Eicosanoids on Dry Eye Symptoms and Signs.

Polyunsaturated fatty acids (PUFAs) generate pro- and anti-inflammatory eicosanoids via three different metabolic pathways. This study profiled tear PUFAs and their metabolites and examined the relationships with dry eye (DE) and meibomian gland dysfunction (MGD) symptoms and signs. A total of 40 individuals with normal eyelids and corneal anatomies were prospectively recruited. The symptoms and signs of DE and MGD were assessed, and tear samples (from the right eye) were analyzed by mass spectrometry. Mann-Whitney U tests assessed differences between medians; Spearman tests assessed correlations between continuous variables; and linear regression models assessed the impact of potential confounders. The median age was 63 years; 95% were male; 30% were White; and 85% were non-Hispanic. The symptoms of DE/MGD were not correlated with tear PUFAs and eicosanoids. DE signs (i.e., tear break-up time (TBUT) and Schirmer's) negatively correlated with anti-inflammatory eicosanoids (11,12-dihydroxyeicosatrienoic acid (11,12 DHET) and 14,15-dihydroxyicosatrienoic acid (14,15, DHET)). Corneal staining positively correlated with the anti-inflammatory PUFA, docosahexaenoic acid (DHA). MGD signs significantly associated with the pro-inflammatory eicosanoid 15-hydroxyeicosatetranoic acid (15-HETE) and DHA. Several relationships remained significant when potential confounders were considered. DE/MGD signs relate more to tear PUFAs and eicosanoids than symptoms. Understanding the impact of PUFA-related metabolic pathways in DE/MGD may provide targets for new therapeutic interventions.

Clinical features of critically ill pregnant and parturient women infected with chronic hepatitis B virus： An analysis of 41 cases / 临床肝胆病杂志

ObjectiveTo investigate the clinical features and outcomes of critically ill pregnant and parturient women with chronic hepatitis B virus （HBV） infection， and to provide clinical experience for the rescue of critically ill pregnant and parturient women and the prevention and treatment of the severe exacerbation of liver disease. MethodsA total of 41 pregnant and parturient women with chronic HBV infection who were admitted to Department of Critical Care Medicine， Nanjing Second Hospital， from March 2013 to March 2023 were enrolled in this study， and their clinical data were collected through the electronic medical record system of hospital to summarize the main causes of transfer to the intensive care unit （ICU）， the causes of death， and treatment. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups. The chi-square test was used for comparison of categorical data between two groups. ResultsAmong the 41 patients， 13 （31.71%） did not receive regular antenatal examination and 8 （19.51%） with a high viral load （HBV DNA ≥2×105 IU/mL） did not receive antiviral therapy. Cesarean section was the main mode of delivery in 32 patients （78.05%）； 23 patients （56.10%） had premature delivery， and 5 patients died （12.20%）. The top three causes of transfer to the ICU were liver failure， postpartum hemorrhage， and hypertensive disorders of pregnancy. Liver failure mainly occurred in late pregnancy， with hepatic encephalopathy as the most common complication （28.57%） and intrahepatic cholestasis of pregnancy as the most common comorbidity （21.43%）； among the 14 patients with liver failure， 6 （42.86%） received regular antenatal examination， and 13 （92.86%） did not receive antiviral therapy before admission. The mean length of ICU stay was 3.31±1.65 days for the patients with postpartum hemorrhage， among whom the patients with severe liver disease had coagulation disorders before delivery， which were difficult to correct after 48 hours of treatment. ConclusionPregnant and parturient women with chronic HBV infection tend to have complex conditions and a relatively high mortality rate. For pregnant and parturient women with chronic HBV infection， assessment of liver status， regular antenatal examination， and timely antiviral therapy are of vital importance to reduce severe exacerbation and mortality rate.

High Physical Activity Volume Is Associated With an Increase in the Calibre of the Lower Limb Veins Without Impact on Functional Discomfort: the VARISPORT Study.

OBJECTIVE: The relationship between physical activity and lower limb veins is complex. If a sedentary lifestyle is considered to be negative on lower limb veins, specific information on physical activity varicose vein volume is sparse, especially the effect of high physical activity volume. The main objective of the VARISPORT study was to evaluate lower limb veins (clinically, morphologically, and haemodynamically) and chronic venous disease symptoms in subjects exposed to high physical activity volume compared with a group of non-exposed subjects. METHODS: A cross sectional study compared a group of high exercise training volume volunteers (more than eight hours of uninterrupted vigorous intensity physical activity per week for more than six months: high physical activity volume group, HPAV group) with a volunteer control group matched for age, sex, and body mass index. Clinical examination was performed to determine the Clinical, Etiological, Anatomical, Pathophysiological (CEAP) classification of each subject and the Carpentier score was used to assess symptoms related to possible chronic venous disease. Duplex ultrasonography was used to assess vein diameters and reflux in the deep and superficial veins. RESULTS: One hundred and nineteen subjects were included in each group. The lower limb veins (deep and superficial) were significantly more dilated in the HPAV group. More reflux was found in the great saphenous veins and non-saphenous veins in the HPAV group. High physical activity volume was associated with a higher frequency of visible varicose veins (stage C2 of the CEAP classification), odds ratio 3.37 (95% confidence interval 1.66 - 7.25) without impact on functional discomfort (44 subjects with a Carpentier score ≥ 1 in each group). CONCLUSION: The VARISPORT study reported an increase in the calibre of the lower limb veins without impact on functional discomfort. Further studies are needed to determine whether these athletic veins are truly pathological varicose veins or simply an adaptation to high physical activity volumes.

TMJ degenerative joint disease: relationships between CBCT findings, clinical symptoms, and signs.

OBJECTIVES: The relationships between cone-beam computed tomography (CBCT) findings, Temporomandibular disorder (TMD) symptoms, and signs were investigated in patients with TMJ degenerative joint disease (DJD). MATERIAL AND METHODS: Adult patients with Diagnostic Criteria for TMDs (DC/TMD)-defined intra-articular conditions were enrolled and subjected to CBCT assessment. The participants were organized into three groups, namely no (NT), early (ET), and late (LT) TMJ DJD based on radiographic findings. TMD symptoms/signs were appraised using the DC/TMD methodology. Statistical analyses were performed using Chi-square/non-parametric tests and Kappa statistics (α = 0.05). RESULTS: The mean age of the participants (n = 877) was 30.60 ± 11.50 years (86.6% women). NT, ET, and LT were observed in 39.7%, 17.0%, and 43.3% of the study sample. Significant differences in the prevalence of TMD symptoms (TMD pain, TMJ sounds, opening, and closing difficulty) and signs (TMD/TMJ pain, TMJ clicking/crepitus, and opening limitation) were discerned among the three groups (p ≤ .001). TMD/TMJ pain and opening difficulty/limitation were more prevalent in early rather than late degenerative changes. While moderate agreements between symptoms and signs were observed for TMD pain/opening limitation, the concurrence for TMJ sounds was fair. CONCLUSIONS: Young adults with TMJ sounds and pain should be examined with CBCT to establish the extent/progress of osseous changes.

Evolution of differences in clinical presentation across epidemic waves among patients with COVID-like-symptoms who received care at the Mexican Social Security Institute.

Background: Timely monitoring of SARS-CoV-2 variants is crucial to effectively managing both prevention and treatment efforts. In this paper, we aim to describe demographic and clinical patterns of individuals with COVID-19-like symptoms during the first three epidemic waves in Mexico to identify changes in those patterns that may reflect differences determined by virus variants. Methods: We conducted a descriptive analysis of a large database containing records for all individuals who sought care at the Mexican Social Security Institute (IMSS) due to COVID-19-like symptoms from March 2020 to October 2021 (4.48 million records). We described the clinical and demographic profile of individuals tested (3.38 million, 32% with PCR and 68% with rapid test) by test result (positives and negatives) and untested, and among those tested, and the changes in those profiles across the first three epidemic waves. Results: Individuals with COVID-19-like symptoms were older in the first wave and younger in the third one (the mean age for those positive was 46.6 in the first wave and 36.1 in the third wave; for negatives and not-tested, the mean age was 41 and 38.5 in the first wave and 34.3 and 33.5 in the third wave). As the pandemic progressed, an increasing number of individuals sought care for suspected COVID-19. The positivity rate decreased over time but remained well over the recommended 5%. The pattern of presenting symptoms changed over time, with some of those symptoms decreasing over time (dyspnea 40.6 to 14.0%, cough 80.4 to 76.2%, fever 77.5 to 65.2%, headache 80.3 to 78.5%), and some increasing (odynophagia 48.7 to 58.5%, rhinorrhea 28.6 to 47.5%, anosmia 11.8 to 23.2%, dysgeusia 11.2 to 23.2%). Conclusion: During epidemic surges, the general consensus was that any individual presenting with respiratory symptoms was a suspected COVID-19 case. However, symptoms and signs are dynamic, with clinical patterns changing not only with the evolution of the virus but also with demographic changes in the affected population. A better understanding of these changing patterns is needed to improve preparedness for future surges and pandemics.

Potential Drug-Drug Interactions among Patients with Schizophrenia Spectrum Disorders: Prevalence, Association with Risk Factors, and Replicate Analysis in 2021.

Background and Objectives: Patients with schizophrenia are often exposed to polypharmacotherapy, which may lead to drug-drug interactions. The aim of the study was to investigate the prevalence of potential drug-drug interactions (pDDIs) in hospitalized patients with schizophrenia spectrum disorders and to identify factors associated with pDDIs and manifested symptoms and signs. Materials and Methods: This cross-sectional observational study included 311 inpatients admitted to a psychiatric hospital. The LexiComp drug interaction program was used to identify pDDIs in 2014. Factors associated with the prevalence of pDDIs and factors related to clinically observed symptoms and signs were assessed using multivariable regression. In addition, replicate analysis of pDDI was performed using 2021 program updates. Results: The prevalence of pDDIs was 88.7%. Our study showed that more than half of the patients received at least one drug combination that should be avoided. The most common pDDIs involved combinations of two antipsychotics or combinations of antipsychotics and benzodiazepines, which can lead to cardio-respiratory depression, sedation, arrhythmias, anticholinergic effects, and neuroleptic malignant syndrome. The number of prescribed drugs was a risk factor for pDDIs (OR 2.85; 95% CI 1.84-5.73). All groups of clinically observed symptoms and signs were associated with the number of drugs. In addition, symptoms and signs characteristic of the nervous system and psychiatric disorders were associated with antipsychotic dosage (IRR 1.33; 95% CI 1.12-1.58), which could contribute to the development of extrapyramidal syndrome, insomnia, anxiety, agitation, and bipolar mania. The 2021 version of the drug interaction program showed a shift in drug interactions toward a lower risk rating, implying less severe patient management and possibly less alert fatigue. Conclusions: Patients with schizophrenia spectrum disorders are at high risk of developing drug-drug interactions. Optimization of drug therapy, patient monitoring, and use of drug interaction programs could help to prevent pDDIs and subsequent adverse drug events.

Clinical features of patients with drug-induced liver injury in Shaanxi Province from 2009 to 2019 / 临床肝胆病杂志

Objective To investigate the clinical features of patients with drug-induced liver injury (DILI). Methods A retrospective analysis was performed for the clinical data of 1 376 patients with DILI who were admitted to 20 hospitals in Shaanxi Province, China, from 2009 to 2019 and were diagnosed with RUCAM scale as the diagnostic criteria, and these patients were analyzed in terms of sex, age, underlying diseases, suspected drugs causing DILI, clinical manifestations, laboratory examination, treatment process, and prognosis. The t -test and Wilcoxon test were used for comparison of continuous data between two groups, the chi-square test was used for comparison of categorical data between groups, and the Kruskal-Wallis H rank sum test was used for comparison of ordered polytomous data between groups. Results Among the 1 376 patients, there were 577(41.93%) male patients and 799 (58.07%) female patients, with a male/female ratio of 0.72:1. As for different age groups, the 40-60 years group had a higher incidence rate and accounted for 44.77%, and there was a significant difference in sex distribution between different age groups ( χ 2 =20.784, P =0.008). As for the three clinical types, there was no significant difference in incidence rate between men and women ( χ 2 =1.409, P =0.494), and there was a significant difference in the distribution of clinical types between different age groups ( χ 2 =47.025, P 0.05). Conclusion There is a high incidence rate of DILI in women and middle-aged and elderly people, and traditional Chinese medicine is the leading cause of DILI. Patients with different clinical types tend to have different prognoses, with a good overall prognosis.

Clinical and Laboratory Features of Enteric Fever in Children and Antibiotic Sensitivity Pattern in a Tertiary Care Hospital of a Low- and Middle-Income Country.

BACKGROUND: Globally, enteric fever (EF) significantly gives rise to an appalling death toll. It is an endemic illness in Bangladesh and South Asia. The condition manifests in a wide range of clinical features in children. Nowadays, antibiotic resistance is an international stumbling block that hampers the appropriate treatment and outcome of EF. OBJECTIVE: The study evaluated the clinical and laboratory characteristics and antibiotic sensitivity pattern of Salmonella enterica in children. METHODS: This prospective research was conducted at Delta Medical College and Hospital, Dhaka, Bangladesh, from January 2017 to December 2019. A total of 200 pediatric cases of EF were included in this study who were either culture positive or had significantly raised Widal test titer for Salmonella with suggestive clinical features. RESULTS: All the patients had a fever, and most had coated tongue, vomiting, abdominal pain, organomegaly, and diarrhea. Among the selected 200 cases of EF, 43.5% were Salmonella typhi culture-positive. A high erythrocyte sedimentation rate (ESR) was observed in a substantial number (53%) of patients. Ceftriaxone was the most sensitive (100%) antibiotic through laboratory analysis, followed by cefotaxime (95.1%). Among the oral antibiotics used, cefixime (92.8%) was the most sensitive. CONCLUSION: EF in children can present with varied clinical manifestations. Selective antibiotic treatment according to sensitivity patterns is crucial for effective illness management and will reduce morbidity and mortality in the pediatric population.

Clinical implications of the universal definition for the prevention and treatment of heart failure.

The diagnosis of heart failure (HF) primarily relies on signs and symptoms that are neither sensitive nor specific. This impedes timely diagnosis and delays effective therapies or interventions, despite the availability of several evidence-based treatments for HF. Through monumental collaborative efforts from representatives of HF societies worldwide, the universal definition of HF was published in 2021, to provide the necessary standardized framework required for clinical management, clinical trials, and research. This review elaborates the key concepts of the new universal definition of HF, highlighting the key merits and potential avenues, which can be nuanced further in future iterations. We also discuss the key implications of the universal definition document from the perspectives of various stakeholders within the healthcare framework, including patients, care providers, system/payers and policymakers.

Improved Dry Eye Symptoms and Signs of Patients With Meibomian Gland Dysfunction by a Dietary Supplement.

Purpose: To explore the therapeutic effect of a dietary supplement on dry eye with meibomian gland dysfunction (MGD). Methods: Sixty patients with MGD-related dry eye were included in this prospective and randomized, placebo-controlled study. All the subjects were treated with eye hot compress, artificial tears, and antibiotic ointment. After that, the patients received dietary supplementary or placebo daily for 12 weeks. The dry eye signs, function of MG, and visual quality of the patients were assessed at 4, 8, and 12 weeks after the treatment. Results: Twelve weeks after the treatment, patients who received dietary supplement had a significantly better improvement of dry eye symptoms, in terms of ocular surface diseases index and tear breaking-up time (TBUT), than those who received placebo (P < 0.05). The functions of MG, in terms of meibum quality and MG exclusion and MG obstruction scores, were significantly improved in both dietary supplement and placebo groups (P < 0.05). Patients who received dietary supplement had a significantly better improvement in the MG structure, in terms of acinar diameter and acinar density, than those who received placebo (P < 0.05). The number of inflammatory cells near MG was significantly lower in the dietary supplement group when compared with the placebo group (P < 0.05). The objective visual quality was significantly improved in the dietary supplement group, but not in the placebo group (P < 0.05). Conclusion: The dietary supplement can effectively improve the symptoms and signs of MGD-related dry eye, reduce the inflammatory reaction of MG, restore the gland structure, and indirectly improve the visual quality.

Clinical manifestation of acute cerebral infarcts in multiple arterial territories.

OBJECTIVES: We aimed to assess frequencies and radiological aspects of single- and multiterritory clinical manifestation among patients with acute cerebral infarcts in multiple arterial territories (MACI). MATERIALS & METHODS: We retrospectively reviewed admission records and diffusion-weighted magnetic resonance imaging of patients with MACI admitted to our stroke unit between 2006 and 2017. MACI was defined as acute cerebral ischemic lesions in at least two out of three arterial cerebral territories, that is, the left anterior, right anterior and the bilateral posterior territory. Patients with single- and multiterritory clinical manifestation were then compared for topographical distribution of the ischemic lesions, the number of ischemic lesions, and The Oxfordshire Community Stroke Project classification. RESULTS: Out of 311 patients with MACI, 222 (71.4%) presented with single-territory clinical manifestation. Involvement of the left hemisphere (OR = 0.37, 95% CI 0.16-0.82), less than five ischemic lesions (OR = 0.58, 95% CI 0.35-0.97), and partial anterior circulation infarct clinical stroke syndrome (OR = 0.57, 95% CI 0.34-0.97) were associated with single-territory clinical manifestation. Involvement of all three territories (OR = 2.58, 95% = 1.48-4.50), more than 10 ischemic lesions (OR = 2.30, 95% CI 1.32-4.01) and total anterior circulation infarct clinical stroke syndrome (OR = 3.31, 95% CI 1.39-7.86) were associated with multiterritory clinical manifestation. CONCLUSION: Most patients with MACI present with single-territory clinical manifestation on admission. Diffusion-weighted magnetic resonance imaging is therefore necessary for a definite diagnosis.

Assessment of neurological symptoms in adult hydrocephalus occlusus. A pilot study.

BACKGROUND: Comprehensively describe and compare (pre/postoperatively) the clinical symptomatology in adult non-communicated hydrocephalus. Associated hydrocephalus signs were analyzed with the idiopathic Normal Pressure Hydrocephalus Scale (iNPH Scale). A standardized clinical scale for non-communicated hydrocephalus is currently not in use. METHODS: Ten patients with hydrocephalus occlusus (HO) were analyzed. Hydrocephalus signs were examined with the iNPH Scale in gait, neuropsychology, continence, and balance before and three months after treatment with shunt operation or third endoscopic ventriculostomy. RESULTS: Patients significantly improved in iNPH total score (25.8%) and gait score (35.4%) three months after neurosurgical intervention. Domain scores in neuropsychology, continence, and balance reached statistical trends (p ≤ 0.066). Most clinical symptoms and signs at baseline improved after surgery (dizziness, lapse of concentration, gait instability, and headache). CONCLUSION: Patients with non-communicated HO also showed classical hydrocephalus symptoms as communicated in iNPH patients. The iNPH Scale allows a structured neurological assessment over the disease's progress and surgical intervention. Further studies with a larger patient samples are necessary to support our results.

The Burden of Cancer-related Neuropathic Pain: A Multi-centric Cross-sectional Observational Study from North India.

INTRODUCTION: Neuropathic cancer pain is a common consequence of cancer itself and anti-cancer treatments. It is a complex phenomenon, often underdiagnosed by physicians or underreported by patients. Its diagnosis and management are usually more challenging than nociceptive pain. There is a dearth of epidemiological evidence for neuropathic pain in cancer patients in India. Screening questionnaires serve as a quick guide to identify potential cases of neuropathic pain. The aim of the present study was to identify the burden of cancer-related neuropathic pain using the Self-reported version of the Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS) pain scale. METHODOLOGY: This was a cross-sectional, observational, multi-centric study conducted at three hospitals in North India. From January 2017 to October 2017, patients attending pain clinic were screened for participation in the study. Adults aged ≥18 years and experiencing the pain of oncologic origin were eligible to participate in the study if they provided informed consent. S-LANSS questionnaire was used to screen patients with neuropathic pain. RESULTS: From a total of 261 patients, who were enrolled in the study, 56.7% were male and their mean age was 50.87 (18-80) years. Fifty-four percent patients had pain with predominantly neuropathic component (S-LANSS score ≥10). CONCLUSION: High burden of neuropathic cancer pain has been observed in outpatient palliative care settings. Early diagnosis of neuropathic pain through screening questionnaires can serve as a quick guide for physicians in resource-constrained settings. This will allow identification of the neuropathic component of pain in patients suffering with mixed pain.

Plasma Vitamin C Concentrations Were Negatively Associated with Tingling, Prickling or Pins and Needles Sensation in Patients with Postherpetic Neuralgia.

Vitamin C deficiency increases the risk of postherpetic neuralgia (PHN). In this cross-sectional study, the relationships among plasma vitamin C concentrations, pain and Leeds assessment of neuropathic symptoms and signs (LANSS) items were investigated during their first pain clinic visit of 120 PHN patients. The factors associated with vitamin C deficiency were determined. Independent predictors of vitamin C deficiency were presented as adjusted odds ratios (AOR) and 95% confidence intervals (CI). The patients had a high prevalence (52.5%) of vitamin C deficiency. Their plasma vitamin C concentrations were negatively associated with spontaneous pain and tingling, prickling or pins and needles sensation according to the LANSS questionnaire. Based on the receiver operator characteristic curve, the cutoffs for plasma vitamin C to predict moderate-to-severe and severe symptoms of sharp sensation were <7.05 and <5.68 mg/L, respectively. By comparison, the patients well-nourished with vitamin C had lower incidences of sharp sensations, sharp pain, and reddish skin. Multivariate analyses revealed that vitamin C deficiency was associated with the low intake of fruit/vegetables (AOR 2.66, 95% CI 1.09-6.48, p = 0.032), peptic ulcer disease (AOR 3.25, 95% CI 1.28-8.28, p = 0.014), and smoking (AOR 3.60, 95% CI 1.33-9.77, p = 0.010). Future studies are needed to substantiate these findings.

Work-Related Musculoskeletal Symptoms in Otorhinolaryngology-Head and Neck Surgery Residents.

OBJECTIVES: Work-related musculoskeletal disorders in Saudi Arabia are not often reported in the literature. This study aimed to identify musculoskeletal symptoms among otorhinolaryngology residents in Saudi Arabia. METHODS: This cross-sectional survey-based study was conducted in May 2018 and included residents registered in the Saudi Otorhinolaryngology-Head and Neck Surgery Board Training programme, Riyadh, Saudi Arabia. The Nordic Musculoskeletal Questionnaire was used to assess musculoskeletal symptoms in addition to demographic and occupational factors, including operating position and the average number of operating hours. RESULTS: A total of 45 residents (response rate: 68.2%) completed the survey, including 33 males (73.3%) and 12 females (26.7%). Most residents (91.1%) reported at least one musculoskeletal symptom. The most commonly reported musculoskeletal over the previous 12 months were shoulder complaints (64.4%) followed by neck complaints (60%). In the short term (i.e. within seven days preceding the survey), neck complaints were more common than shoulder complaints (28.9% versus 20%). Lower back complaints were the most common cause of activity limitation (24.4%) followed by shoulder complaints (13.3%), while those with neck complaints reported it as a cause for visiting a physician (8.9%). Hip and thigh complaints were significantly more frequent among residents with operation times of eight hours or more compared to those who operating for less than eight hours (42.9% versus 5.9%; P = 0.021). CONCLUSION: A high incidence of shoulder, neck and lower back complaints was found in this study. Residency is an ideal time in an otorhinolaryngologist's career to implement programmes in ergonomic best practices before bad habits are developed.

The role of nonacid reflux in laryngopharyngeal reflux diseases.

OBJECTIVE: To analyze the role of nonacid reflux in laryngopharyngeal reflux diseases (LPRD). METHODS: From January 2014 to April 2019, 344 patients associated with LPRD underwent 24-h multichannel intraluminal impedance-pH monitoring, and their reflux symptom index (RSI) and reflux finding score (RFS) were recorded. The numbers of acid, weakly acidic and alkaline reflux events in the laryngopharynx were counted, and the consistency analysis of the results with the results of the RSI and RFS was conducted. RESULTS: Among the 344 patients, nonacid reflux events accounted for 74.1% (1367/1845) of the all reflux events. There were 111 patients with ≥ 3 acid reflux events, 218 patients with ≥ 3 any kinds of reflux events, and 257 patients with positive results of RSI or RFS. Taking the results of the RSI and or RFS as a reference, the sensitivity, specificity and consistency test Kappa value for the diagnosis of LPRD according to the existence of ≥ 3 acid reflux events were 41.2%, 94.2% and 0.228, respectively. With the existence of three or more all kinds of reflux events as the standard, the sensitivity, specificity and consistency test Kappa value were 76.7%, 74.7% and 0.449, respectively. CONCLUSION: The nonacid reflux events account for the highest proportion of laryngopharyngeal reflux events, and the consistency of the results of RSI and or RFS with all reflux events is higher than that with only acid reflux events, that indicates nonacid reflux may play an important role in LPRD.

Clinical characteristics and prognosis of patients with anti-neutrophil cytoplasmic antibody-associated vasculitis / 第二军医大学学报

Objective: To analyze the clinical characteristics and prognosis of patients with anti-neutrophil cytoplasmic antibodies (ANCA) associated vasculitis (AAV). Methods: Clinical data (general information, clinical manifestation, and laboratory indexes) of 168 patients newly diagnosed as AAV between Jul. 2008 and Dec. 2016 were retrospectively analyzed. Patients were followed up for a median period of 12 months (range, 1-96 months). End-point event was death. Results: There were 152 cases of microscopic polyangiitis (MPA), 14 cases of granulomatous polyangiitis (GPA) and 2 cases of eosinophilic granulomatosis with polyangiitis (EGPA). MPO-ANCA was positive in 145 (86.3%) patients and PR3-ANCA was positive in 20 (11.9%) patients. Forty-nine patients died, 91 patients survived, and 28 patients lost their visits. Interstitial lung disease and renal involvement were more common in MPA patients as compared with GPA patients (50.7% [77/152] vs 14.3% [2/14], 78.9% [120/152] vs 50.0% [7/14], all P<0.05). Estimated glomerular filtration rate (eGFR) in MPA patients was significantly lower than that in GPA patients (14.23 [7.27, 71.49] mL/[min · 1.73 m2] vs 104.08 [16.61, 135.72] mL/[min · 1.73 m2], P<0.05). Compared with PR3-ANCA positive patients, MPO-ANCA positive patients was more elder ([64.01 ± 10.62] years vs [50.50±16.88] years), had more renal involvement (77.9% [113/145] vs 50.0% [10/20]) and lower eGFR (19.00 [9.40, 42.85] mL/[min · 1.73 m2] vs 149.40 [86.75, 249.45] mL/[min · 1.73 m2], all P<0.05). Compared with the survivals, the dead patients were older ([67.45±10.61] years vs [61.98 ± 12.52] years), had higher incidence of interstitial lung disease (59.2% [29/49] vs 41.8% [38/91]), higher Birmingham vasculitis activity score (BVAS) (18.53 ± 8.02 vs 13.68 ± 5.98), lower eGFR (8.58 [5.73, 22.07] mL/[min · 1.73 m2] vs 45.15 [11.54, 120.79] mL/[min · 1.73 m2], lower blood sodium concentration (137.00 [134.00, 140.00] mmol/L vs 139.00 [136.00, 141.00] mmol/L), lower albumin level ([28.41 ± 5.24] g/L vs [31.92 ± 5.91] g/L), and higher serum D-dimer level (2.84 [1.20, 6.28] mg/L vs 2.24 [0.80, 3.69] mg/L) (all P<0.05). Multivariate Cox proportional regression analysis showed that age, eGFR, serum albumin level and BVAS were independent influence factors of death (hazard ratio =1.058, 0.987, 0.932, and 1.086, all P<0.05). Conclusion: The clinical manifestations of AAV are mostly pulmonary and renal involvement. Age, eGFR, serum albumin level and BVAS are independent risk factors of death in AAV patients. Interstitial lung disease, high level of D-dimer and hyponatremia may be associated with prognosis of AAV.

Is Fibromyalgia Syndrome a Neuropathic Pain Syndrome?

OBJECTIVES: This study aims to investigate whether fibromyalgia syndrome (FMS) represents a neuropathic pain syndrome through the use of neuropathic pain scales. PATIENTS AND METHODS: The study included 99 female patients (mean age 44.21 years; range, 18 to 65 years) who referred to Physical Therapy and Rehabilitation Department Outpatient Clinics with complaints of widespread pain and who received a clinical diagnosis of fibromyalgia based on the 1990 American College of Rheumatology diagnostic criteria and a control group consisting of 86 female patients (mean age 49.21 years; range, 18 to 65 years) who were diagnosed with acute subacromial impingement as a nociceptive pain model. All patients completed the Turkish version of the Fibromyalgia Impact Questionnaire (FIQ), the Beck Depression Scale (BDS), the 10 cm Visual Analog Scale for pain assessment, the Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) pain questionnaire for neuropathic pain assessment and the painDETECT scale. RESULTS: An evaluation of the patients' symptoms indicated that complaints of numbness, burning, tingling, morning stiffness, insomnia, fatigue and weakness were significantly more common in the fibromyalgia group compared to the controls. Moreover, the mean scores of the BDS, FIQ, painDETECT and LANSS pain scale were significantly higher in the fibromyalgia group compared to the controls. Statistically significant correlations were noted between FIQ values and LANSS, and the BDS and painDETECT results in the fibromyalgia group. CONCLUSION: The present study demonstrates that sensorial symptoms such as paraesthesia, hyperalgesia and allodynia were more common and the scores of neuropathic pain scales such as painDETECT and LANSS were significantly elevated in the fibromyalgia patients compared to the control group, and these findings suggest that FMS may have a neuropathic pain component.
