Pudendal Nerve Terminal Motor Latency Compared by Anorectal Manometry Diagnosing Fecal Incontinence: A Retrospective Study.

OBJECTIVE: The aim of the study was to compare the clinical value of pudendal nerve terminal motor latency in fecal incontinence patients with that of another diagnostic test-anorectal manometry. DESIGN: This study used a cross-sectional design. Medical records of fecal incontinence patients who underwent pudendal nerve terminal motor latency and anorectal manometry testing were reviewed. Greater than 2.4 ms of pudendal nerve terminal motor latency was determined to be abnormal. Anorectal manometry was performed using a station pull-through technique. Mean resting anal pressure, maximal resting anal pressure, mean squeezing anal pressure, and maximal squeezing anal pressure were investigated. For normal and abnormal pudendal nerve terminal motor latency groups, comparative analyses were performed on anorectal manometry results. RESULTS: A total of 31 patients were included. Thirteen patients showed normal pudendal nerve terminal motor latency. For anorectal manometry results, there was no significant difference between normal and abnormal pudendal nerve terminal motor latency groups. Fourteen patients had diabetes mellitus. Subgroup analysis of the 14 diabetic patients showed no significant difference between normal and abnormal pudendal nerve terminal motor latency groups. For 17 nondiabetic patients, there was a significant difference between the groups with positive correlations with mean/maximal resting anal pressures. CONCLUSIONS: Pudendal nerve terminal motor latency significantly correlates with anorectal manometry in fecal incontinence only in nondiabetic patients.

Exercise-based pulmonary rehabilitation for a post-COVID-19 pulmonary fibrosis patient: A case report.

RATIONALE: Pulmonary fibrosis is an infamous sequela of coronavirus disease 2019 (COVID-19) pneumonia leading to long-lasting respiratory problems and activity limitations. Pulmonary rehabilitation is beneficial to improve the symptoms of lung fibrosis. We experienced a post-COVID-19 pulmonary fibrosis patient who received a structured exercise-based pulmonary rehabilitation program. PATIENT CONCERNS: This article presents a case of successful pulmonary rehabilitation of a patient with post-COVID-19 pulmonary fibrosis. The patient could not cut off the oxygen supplement even after a successful recovery from COVID-19. DIAGNOSIS: Diagnosis of COVID-19 was based on the reverse transcription-polymerase chain reaction (RT-PCR). Pulmonary fibrosis was diagnosed by patient's complaint, clinical appearance, and computed tomography (CT) on chest. INTERVENTION: The patient underwent ten sessions of exercise-based rehabilitation program according to Consensus Document on Pulmonary Rehabilitation in Korea, 2015. OUTCOME: On the 8th day, he could cut off the oxygen supplementation and complete the one-hour exercise without oxygen. He was discharged after completing the 10-session program without any activity limitations. LESSONS: Exercise-based pulmonary rehabilitation will help the post-COVID-19 pulmonary fibrosis patients. This case suggested the importance of pulmonary rehabilitation program to the post-COVID-19 pulmonary fibrosis patient.

Correlation of Videofluoroscopic Swallowing Study Findings With Radionuclide Salivagram in Chronic Brain-Injured Patients.

OBJECTIVE: To investigate the correlation between videofluoroscopic swallowing study (VFSS) and radionuclide salivagram findings in chronic brain-injured patients with dysphagia. METHODS: Medical records of chronic brain-injured patients who underwent radionuclide salivagram and VFSS were retrospectively analyzed. Patients were divided into two groups according to salivagram findings. Differences in patient characteristics and clinical factors, including Mini-Mental State Examination (MMSE), Modified Barthel Index (MBI), Functional Ambulatory Category (FAC), feeding method, tracheostomy state, and VFSS findings between the two groups were investigated. RESULTS: A total of 124 patients were included in this study. There were no significant differences in MMSE, MBI, FAC, feeding method, and presence of tracheostomy between the two groups. However, the incidence of aspiration pneumonia history was significantly higher in the positive salivagram group. The Functional Dysphagia Scale (FDS) was significantly associated with positive salivagram findings, especially in the pharyngeal phase. A multivariate logistic regression analysis showed that laryngeal elevation and epiglottic closure was statistically significant FDS parameter in predicting salivary aspiration on a salivagram (odds ratio=1.100; 95% confidence interval, 1.017-1.190; p=0.018). The receiver operating characteristic (ROC) curve of FDS in the pharyngeal phase showed that an optimum sensitivity and specificity of 55.1% and 65.4%, respectively, when the cut-off value was 39. CONCLUSION: In chronic brain-injured patients, inappropriate laryngeal elevation and epiglottic closure is predictive variable for salivary aspiration. Therefore, performing a radionuclide salivagram in patients with FDS of 39 or less in the pharyngeal phase for prevents aspiration pneumonia from salivary aspiration.
