Anorectal Manometric and Urodynamic Parameters According to the Spinal Cord Injury Lesion

OBJECTIVE: To assess the correlation between the anorectal function and bladder detrusor function in patients with complete spinal cord injury (SCI) according to the type of lesion. METHODS: Medical records of twenty-eight patients with SCI were included in this study. We compared the anorectal manometric and urodynamic (UD) parameters in total subjects. We analyzed the anorectal manometric and UD parameters between the two groups: upper motor neuron (UMN) lesion and lower motor neuron (LMN) lesion. In addition, we reclassified the total subjects into two groups according to the bladder detrusor function: overactive and non-overactive. RESULTS: In the group with LMN lesion, the mean value of maximal anal squeeze pressure (MSP) was slightly higher than that in the group with UMN lesion, and the ratio of MSP to maximal anal resting pressure (MRP) was statistically significant different between the two groups. In addition, although the mean value of MSP was slightly higher in the group with non-overactive detrusor function, there was no statistical correlation of anorectal manometric parameters between the groups with overactive and non-overactive detrusor function. CONCLUSION: The MSP and the ratio of MSP to MRP were higher in the group with LMN lesion. In this study, we could not identify the correlation between bladder and bowel function in total subjects. We conclude that the results of UD study alone cannot predict the outcome of anorectal manometry in patients with SCI. Therefore, it is recommended to perform assessment of anorectal function with anorectal manometry in patients with SCI.

Analysis of Pulmonary Function Test in Korean Patients With Duchenne Muscular Dystrophy: Comparison of Foreign and Korean Reference Data

OBJECTIVE: To determine the abnormal pulmonary function value in Korean Duchenne muscular dystrophy (DMD) patients, we performed a comparative analysis of the patients' pulmonary function value expressed as % of the overseas reference data and Korean healthy children and adolescent reference data. METHODS: We performed pulmonary function test (PFT) in a total of 27 DMD patients. We compared the patients' FVC% and FEV1% of the overseas reference data with those of the Korean children and adolescent reference data. Also, we compared the patients' MIP% and MEP% of the prediction equation data with those of the Korean children and adolescent reference data. RESULTS: Age of the subjects ranged from 8 to 16 years (12.03±2.27 years). The mean maximal expiratory pressure (MEP), maximal inspiratory pressure (MIP), vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), and peak cough flow (PCF) were 36.93±9.5 cmH₂O, 45.79±17.46 cmH₂O, 1.4±0.43 L, 1.45±0.45 L, 1.40±0.41 L, and 206.25±61.21 L/min, respectively. The MIP%, MEP%, and FVC% of the Korean children and adolescent reference data showed statistically significant higher values than those of the prediction equation data. CONCLUSION: We observed a clear numeric difference between Korean DMD patients' pulmonary function value expressed as % of the overseas data and inland data. To perform a precise assessment of respiratory function and to determine appropriate respiratory therapy, pulmonary function values of Korean DMD patients should be interpreted taking into account the inland normal pulmonary function test data.
