Bilateral renal dysplasia in a ferret (Mustela putorius furo)

AbstractRenal dysplasia is a histological diagnosis characterised by disorganised architecture of the renal cortex and medulla with disrupted nephron differentiation and primitive ducts surrounded by collarettes of the mesenchymal tissue. This condition has been reported once previously in ferrets as a component of multiple congenital abnormalities of the urogenital tract. A 1.5‐year‐old, male, neutered ferret was presented after being found minimally responsive under a fallen shelf in its enclosure. The ferret was obtunded, with mild intermittent muscle tremors and severe dehydration. Survey radiographs, including thoracic and abdominal ventrodorsal and right and left lateral views, were performed to assess for general trauma. The right renal silhouette was normal in size, and the left was moderately reduced. The capsular margins of both renal silhouettes were moderately undulating and mildly indistinct with perirenal retroperitoneal striations. No signs of trauma or other abnormalities were identified. Whole blood biochemical analysis demonstrated elevated creatinine, elevated blood urea nitrogen, hypernatraemia, hypercalcaemia, hyperphosphataemia and hyperproteinemia characterised by hyperalbuminemia and haemoconcentration. The hypernatraemia and mentation failed to improve with intravenous fluid therapy, and the ferret was euthanased. Bilateral renal dysplasia was confirmed via gross postmortem examination and histopathology.

Yield of abdominal radiographs in children with suspected intussusception; rate of pneumoperitoneum and other abdominal pathology

ObjectivesUltrasound is the criterion standard imaging modality for the diagnosis of intussusception. However, to our knowledge the utility of abdominal radiographs to concurrently screen for pneumoperitoneum or other abdominal pathology that could have a similar presentation has not been studied. Our institutional protocol requires the performance of AP supine and left lateral decubitus views of the abdomen prior to ultrasound evaluation for intussusception, providing an opportunity to examine the yield of abdominal radiographs in this setting.Our primary objective was to determine the rate of pneumoperitoneum on screening abdominal radiographs in children undergoing evaluation for intussusception. Our secondary objective was to determine the rate that other clinically significant pathology is found on these screening abdominal radiographs. MethodsWe performed a retrospective chart review of all patients under 6 years of age who had any imaging ordered in our large urban pediatric emergency department to evaluate for suspected intussusception during the calendar years 2018–2020. Results1115 patient encounters met our inclusion criteria. Among 1090 who had screening abdominal radiographs, 82 (8%) had findings concerning for intussusception. Of those not concerning for intussusception, 635 (58%) were read as normal, 263 (24%) showed moderate to large stool burden, 107 (10%) showed generalized bowel distention, and 22 (2%) showed abnormal gastric distention. Individually the remainder of all other findings compromised <1% of encounters and included radiopaque foreign body (8), intraabdominal calcification (4), pneumonia/effusion (3), pneumatosis intestinalis, abdominal mass (2), diaphragmatic hernia (1), rib fracture (1), appendicolith (1), feeding tube malposition (1), and bowel wall thickening (1). In one encounter the patient had a bowel perforation with pneumoperitoneum present secondary to ingestion of multiple magnets. ConclusionsOur study indicates that radiograph-detected pneumoperitoneum is rare in children with suspected intussusception. Constipation is the most common abnormal finding on screening radiographs. Other findings occur in approximately 15% of total cases, some of which require further workup.

Nasal Measurements in Indian Population of North-East Region: Angular Parameters with Literature Review.

Just like linear nasal parameters, angular nasal parameters form the basis of any rhinoplasty, especially in various ethnic groups to maintain the specific racial characteristics while creating an aesthetic nose. The objective of this study was to measure and study the outcomes of angular nasal parameters in north-east Indians and to contrast them with available literature on Oriental, Caucasian and Indian population in general. This cross-sectional study was carried out in 150 young adults from north-east region of India. Surface landmarks were marked, and standard photographs were taken. Nine angular parameters were measured from the left lateral and basal view photographs of the face using computer software. Data were analysed by Student's 't'-test for parametric data and Mann-Whitney U-test for non-parametric data using SPSS v.25. All the angular measurements were found to be greater in females except nasofacial angle, columella tip angle and interaxial angle. Differences in nasofrontal angle, columella labial angle, nasofacial angle and columella tip angle between males and females were statistically significant. Nasofrontal and columella labial angles were more acute in the study population compared to Caucasians, Orientals and other Indians while nasofacial, interaxial and interalar angles were larger. The north-east Indian nose is dissimilar to that of rest of the country as well as that of Caucasians and Orientals with respect to angular parameters.

A novel radiographic projection for the detection of a scapula body fracture in a Thoroughbred foal

SummaryThis case report describes the clinical and diagnostic imaging findings, treatment and outcome of a 3‐month‐old Thoroughbred foal referred for the evaluation of severe left forelimb lameness and presents the acquisition of a novel radiographic projection of the scapula used to achieve the diagnosis. No abnormalities were found with the standard radiographic examination of the left shoulder. A right dorsal 45° lateral‐ left ventral lateral oblique radiographic view was performed to evaluate the body of the left scapula. A longitudinal, minimally displaced fracture of the infraspinous fossa was diagnosed with this projection. Ultrasound was used in conjunction to confirm the diagnosis, assess the displacement of the fracture in the sagittal plane and evaluate soft tissue damage. The foal was treated conservatively with anti‐inflammatory drugs and stall rest. A radiographic follow‐up and clinical reassessment were performed, and the horse appeared sound, no atrophy of the region was appreciated and no radiographic abnormalities were found.

Radiologic evaluation of thoracic size in the Nigerian indigenous dog by vertebral, haller and frontosagittal indices

Reproducible and easily applied measurements for radiologic evaluation are needed in the day-to-day clinical practice for diagnosis and treatment or management of thoracic disorders in the Nigerian Indigenous Dog. The objective of this prospective cross-sectional study was to document measurement indices used for the evaluation of canine thoracic silhouette. Thirty healthy Nigerian Indigenous Dogs, 10 puppies and 20 adults of average body weight 8.19±2.45 kg and comprising equal number of both sexes. Ninety survey dorsoventral, right lateral and left lateral thoracic radiographs of the animals were obtained. The shape of the thoracic silhouette in each radiograph was objectively evaluated and adequately described. In the right and left lateral views, sternovertebral distance and sagittal vertebral diameter of the tenth vertebra were measured and recorded; while the dimension measured in the dorsoventral view was costocostal distance. In the lateral radiographs, mean values of vertebral indices (VI) for right/left lateral radiographs were 0.10±0.00/0.10±0.00, respectively. Results of normal thoracic silhouette determined in dorsoventral versus right lateral orthogonal radiographs were: frontosagittal index (FSI) 1.06±0.05 and Haller index (HI) 0.95±0.04. The clinical relevance of this investigation is that it provides measurement indices for the morphological evaluation of the thoracic silhouette in the Nigerian Indigenous Dog. These indices are reproducible, objective and easy to apply in small animal clinical practice.

Mucormycosis in compound grade IIIa tibial plafond with medial malleolus fracture: A case report

Tibial plafond fracture is defined by intra articular involvement of the distal tibia with metaphyseal extension. The plafond fracture accounts for less than 1% of lower limb injuries and 3–10% of tibial fractures. The rate of deep infection in open ankle fractures is approximately 5%. Pilon fractures are frequently associated with severe soft- tissue injuries that alter the management plan. Here we describe the case of 35year old man brought to ER after sustaining machinery injury to right ankle. On local examination a Laceration of 7x2x2 cms present over left ankle anteriorly extending from Medial Malleolus to Lateral Malleolus and cut ends of tendons of extensor digitorum longus, extensor hallucis longus and Tibialis anterior were identified. X-ray left ankle Ap and Lateral views were taken. X-ray showed Left Distal Tibia fracture. Thorough Wound wash given. Under spinal anesthesia debridement of wound was done and K-wire fixation done for distal tibia fracture. Tendon repair for extensor digitorum longus, extensor hallucis longus and tibialis anterior done using Ethibond suture material using Modified Kessler Technique. On 2 Post operative day a swab from the wound site sent for culture and sensitivity which revealed fungal growth of zygomycetes species. In view of angioinvasive properties of Zygomycetes, after checking Renal parameters patient was started on Inj Amphotericin B 1mg/kg for 4 days and later converted to Tablet Posaconazole 600mg BD. Patient was kept on posaconazole tablet for 6weeks. Regular dressings were done. On regular follow ups and regular dressings wound healed well.

Accuracy of Teledentistry for Diagnosis and Treatment Planning of Pediatric Patients during COVID-19 Pandemic.

Teledentistry is a new technology in the dentistry field, which has great benefits during pandemic such as the coronavirus disease 2019 (COVID-19). The overall purpose of the study was to assess the diagnostic sensitivity and specificity of virtual (mobile phone teledentistry) compared with clinical examinations during COVID-19. The basic design of the study was based on the comparison treatment plans by the students and the gold standard (clinical treatment plan of an expert pedodontist with 10 years of clinical experience). This double-blind clinical trial was conducted on 20 children (aged 6 to 12 years) with a chief complaint of dental caries with or without pain. An appropriate radiograph and five standard intraoral photographs (frontal view occlusion, maxillary occlusal view, mandibular occlusal view, right lateral view, and left lateral view) were prescribed for each patient according to the guidelines of the American Association of Pediatric Dentistry. Then, the treatment plan for the carious teeth was recorded for each patient. Each patient underwent a clinical examination at first and was followed randomly by a virtual examination by two dental students. Then, the clinical and virtual treatment plans were compared with each other, and also with the gold standard. The sensitivity and specificity values were calculated for each group. The accuracy of the diagnosis was measured by applying Cohen's kappa. Interexaminer reliability was measured using the intraclass correlation coefficient (ICC) and Cronbach's alpha. The mean kappa coefficient for the interexaminer agreement (for 24 teeth) was 0.62 in clinical and 0.69 in virtual examinations. The results showed no significant difference in the treatment plans of students and the gold standard (P > 0.05). The diagnostic sensitivity and specificity were 73.22% and 95.8% for clinical and 76.44% and 92.9% for virtual treatment plans showing no significant differences between virtual (mobile phone teledentistry) and clinical examinations (P > 0.05). The intraexaminer reliability of the examiners was found to be 0.92 by calculating the ICC. Then, teledentistry can be considered as a supplement to clinical examinations of pediatric dentistry, finally resulting in better patient management. However, more studies are necessary for teledentistry.

Hunminjeongeum Phonetics (II): Phonetic and Phoniatric Consideration for Explanation of Designs of Initial and Final Consonant Letters

Hunminjeongeum had 17 initial consonant letters. Among them, five consonant letters, those are ㄱ (牙音, molar sound letter), ㄴ (舌音, lingual sound letter), ㅁ(脣音, labial sound letter), ㅅ (齒音, dental sound letter), ㅇ (喉音, guttural sound letter), were served as chief consonants. There was no argument that consonant letters were made by symbolizing the shape of vocal organs during phonation of them. It could be phoniatrically explained that all of five chief consonants were morphologically symbolized from left lateral view of vocal tract during articulation. Although ‘ㄱ’ was known as molar sound, it was not modeled the shape of molar tooth but modeled the shape of tongue at molar teeth bearing area. The same principle applies to ‘ㅅ’, and it was represented the shape of upper surface of anterior tongue instead of incisor teeth. ‘ㄴ’ was a lingual sound and directly shaped the shape of tongue. ‘ㄷ’ was made by addition of a stroke ‘ㅡ’ meaning hard palate above ‘ㄴ’. ‘ㅁ’ was represented the shape of lateral view of anterior mouth. ‘ㅇ’ was looked like shaping left lateral view of laryngopharyngeal space.

Evaluation of tracheal size in the Nigerian indigenous dog by radiologic morphometry

Reproducible and easily applied methods of radiologic evaluation are needed in the day-to-day clinical practice for diagnosis and treatment (management) of tracheal disorders in animals. In the Nigerian Indigenous Dog, records of such measurements are either non-existent or invisible. The objective of this prospective cross-sectional study was to document measurement indices used for the evaluation of canine trachea. Thirty healthy Nigerian indigenous dogs of both sexes were used for the investigation. Plain right and left lateral thoracic radiographs of each research animal were obtained. The tracheal silhouette in each radiograph was objectively evaluated and adequately described. In the right and left lateral views, the sagittal diameter of the tenth vertebra, the thoracic inlet diameter, and the tracheal diameter were the parameters measured and recorded. Indices generated were the tracheothoracic ratio and tracheovertebral ratio. Results were described as means ± standard errors of means while differences between mean values were subjected to student’s t-test statistic using SPSS version 22 for windows. Statistical significance was established at P≤0.05. In the lateral radiographs, mean values of vertebral indices, tracheothoracic ratios, and tracheovertebral ratios for right/left lateral radiographs were 0.21±0.01/0.21±0.01, and 0.92±0.12/0.92±0.11, respectively. Using the right lateral and dorsoventral orthogonal views, the fronto-sagittal and Haller index's mean values were 1.05±0.04 and 0.95±0.04, respectively. The indices generated in the present study are considered adequate and recommended for morphological evaluation of the canine tracheal silhouette. The tracheovertebral ratio was established for the first time in the present research. The results of this work are reproducible, objective and easy to apply in small animal clinical practice.

Posture and quality of life in children with hemiparesis

Aim of the study: Evaluate posture and quality of life in children with hemiparesis and assess the relation between them. Study Design: the observational-cross-sectional study was conducted in the National Institute of Neuromotor System in Giza Governorate. Subjects &amp; Methods: Sixty children with hemiparesis cerebral palsy, 28 girls and 32 boys whose ages ranged from 6 to 10 years old, participated in this study. The Postural assessment software (PAS/SAPO) was used to assess their body posture from digitalized pictures (anterior, posterior, right, and left lateral views). The quality of life of participating children was evaluated through the Pediatric Quality of Life Inventory Version 4.0 (PedsQL 4.0). All statistical measures were carried out using the statistical SPSS package program. Results: Postural deviations of children with hemiparesis were characterized by the asymmetry of acromions, anterior superior iliac spine (ASIS), and scapula alignments from the anterior and posterior view. It also adopted head, trunk, and knee flexion and reduced ankle angle from lateral views. There was a decrease in PedsQL 4.0 scores (all domains and the total score).

Alteração postural, dor lombar e a resistência dos músculos do tronco em jovens universitárias

Abstract Introduction: Low back pain, the most prevalent musculoskeletal disorder, is common in individuals with postural changes and has a high incidence in university students. Trunk muscle instability and weakness can contribute to the presence of low back pain. However, no research has investigated the relationship between low back pain in conjunction with postural changes and the resistance of the trunk stabilizing muscles. Objective: To analyze the correlation between postural alterations and muscular resistance of the trunk of women with and without low back pain. Methods: Forty university women were recruited and divided into a group with low back pain (n = 20; 20.85 ± 1.69 years) and a group without low back pain (n = 20; 20.05 ± 2.54 years). On the first day, the postural assessment was carried out by photogrammetry with Kinovea software. On the second day, the resistance tests of the trunk flexor and extensor muscles, lateral and ventral plank, bridge, and lumbar traction were performed through the traction dynamometer. Pearson's correlation test was applied to verify the relationship between the analyzed variables, Student's T test was used for comparison between groups, and a significance level of p &lt; 0.05 was adopted. Results: There was no correlation between the variables related to postural changes and muscle resistance tests (p &gt; 0.05). There was a difference between the groups only for the bridge exercise test (p = 0.04) and vertical alignment of the head, left lateral view (p = 0.041), and right lateral view (p = 0.034). Conclusion: This study did not show a direct and significant relationship between postural changes in young university students with and without complaints of low back pain and resistance of the trunk-stabilizing muscles.

Radiographic Mensuration of Caudal Vena Cava, Aorta, Vertebral Length and Fourth Rib Width and Ascertaining their Ratios in Healthy Dogs

Background: Caudal vena cava generally travels from the abdominal cavity to the right atrium and visible on lateral thoracic radiograph. Dilation of Caudal vena cava is generally considered as an abnormality for diagnosis of right-side heart failure. Normal range of ratio of caudal vena cava to associated structures can help in differentiating normal dogs from abnormal dogs. The present study was aimed to find such ratio in normal dogs and their clinical relevance. Methods: The present study was conducted on 19 healthy dogs of either sex belonging to different age-groups presented to the Department. They were anaesthetized and subjected to thoracic radiography in standard positions. The width of caudal vena cava (CVC), the descending aorta (AO), right fourth thoracic rib (R4) and the length of thoracic vertebrae (VL) were measured in left lateral (LeL) radiographic views to calculate ratios like CVC/AO, CVC/VL, CVC/R4, AO/VL, AO/R4. Result: The results revealed a wider range of some of such ratios than those reported so far by other workers for healthy dogs. Moreover, a wide variation in shape of CVC and size of R4 was noticed in individuals. It is concluded that the existing range of such ratio needs to be modified for better clinical relevance and overall such ratios do not represent a sensitive diagnostic modality.

Quantifying Inter- and Intrasexual Head-Shape Polymorphism in Eurycea cf. wilderae (Blue-Ridge Two-Lined Salamanders)

Distinct morphological differences between and within sexes may reflect reproductive behaviors that have evolved under natural and sexual selection. In some members of the Eurycea bislineata (Two-Lined Salamander) species complex, inter- and intrasexual variation in head morphology result from secondary sexual characters used in locating, courting, and guarding mates. In populations of Eurycea cf. wilderae (Blue-Ridge Two-Lined Salamander), males possess one of two suites of morphological traits corresponding to alternative reproductive tactics. “Searching” males appear to be adapted for locating and courting females in terrestrial habitats and are characterized by the seasonal development of mental glands, protruding premaxillary teeth, and elongate cirri. “Guarding” males appear to be adapted for aggressively guarding females in aquatic habitats, lack all three aforementioned traits, and are instead characterized by seasonally enlarged jaw musculature. Traditionally, males have been categorized by treating these traits as binary (i.e., present or absent), but this fails to capture any continuous variation. Here, we evaluated the utility of geometric morphometric methods to quantify and describe differences in head morphology among female, searching male, and guarding male E. cf. wilderae. In the left-lateral view, we found significant pairwise differences among all three morph–sex groups. In the ventral view, we found significant pairwise differences between searching males and guarding males and between searching males and females, but not between guarding males and females. Deformation grids clearly demonstrated the enlarged jaw musculature of guarding males and wider, flatter rostrum of searching males. Our results demonstrate utility of geometric morphometric methods for describing head shape differences among these alternative reproductive tactics and provide baseline data for future studies of spatial and temporal variation.

Evaluation of Picosecond 755-nm Alexandrite Laser With a Diffractive Lens Array on Pore Size Reduction.

Medications, lasers and light therapy have all been shown to transiently minimize pore size. Current research of the 755-nm Alexandrite picosecond laser (Cynosure, MA) on pore size shows differing results regarding the efficacy, with one study of Asian volunteers (Fitzpatrick skin type IV) reporting &ldquo;marked&rdquo; improvement of pores, yet another study reporting no significant improvement in pore size in Chinese patients (Fitzpatrick skin type III&ndash;IV), causing some contention. This study aims to rectify the discordant results through the examination of the 755-nm Alexandrite picosecond laser on pore size reduction in a sample consisting of Fitzpatrick skin type I&ndash;III. Patients who received 755-nm Alexandrite picosecond laser treatment for photorejuvenation, (6 mm lens array) with a fluence of 0.71 J/cm2 of the face or head, with at least two treatments over four-week intervals were included in the study. A precision subject imaging system (Canfield VISIA&reg; Complexion Analysis Generation 7, NJ) was used to assess three parameters of pore size (feature count, score, percentile rank) at each time period at right lateral, left lateral and frontal views. A Wilcoxin signed rank test was performed to compare differences between time periods and a mixed model ANOVA was utilized to account for patients who received less than three treatments. Significance level set to P=&lt;0.05. 32 participants met criteria and underwent at least two picosecond laser treatments for photorejuvenation. There was an overall reduction in pore count in approximately 57% of participant data points from times 1 to 2 and 50% reduction from times 2 to 3. There was a 100% pore count reduction observed from baseline compared with the follow-up visit four weeks after the third treatment, at time 4. Further, there was a significant improvement of pores demonstrated by score from times 1 to 3 (Z= -2.197, P=0.028) as well as percentile rank between times 1 and 2 (Z= -2.070, P=0.038) and times 1 and 3 (Z= -2.201, P=0.028). Future studies should investigate the longterm effect of 755-nm Alexandrite picosecond laser on pore size reduction as continued patient recruitment and data collection is necessary to effectively discern the 755-nm Alexandrite picosecond laser debate. Thus, prolonged follow up post treatment should be evaluated in order to determine if results are maintained. Nonetheless, the 755-nm Alexandrite picosecond laser shows promising results for the improvement of skin pores thus far. J Drugs Dermatol. 2021;20(12):1302-1306. doi:10.36849/JDD.6199.

Cephalopod species identification using integrated analysis of machine learning and deep learning approaches.

BackgroundDespite the high commercial fisheries value and ecological importance as prey item for higher marine predators, very limited taxonomic work has been done on cephalopods in Malaysia. Due to the soft-bodied nature of cephalopods, the identification of cephalopod species based on the beak hard parts can be more reliable and useful than conventional body morphology. Since the traditional method for species classification was time-consuming, this study aimed to develop an automated identification model that can identify cephalopod species based on beak images.MethodsA total of 174 samples of seven cephalopod species were collected from the west coast of Peninsular Malaysia. Both upper and lower beaks were extracted from the samples and the left lateral views of upper and lower beak images were acquired. Three types of traditional morphometric features were extracted namely grey histogram of oriented gradient (HOG), colour HOG, and morphological shape descriptor (MSD). In addition, deep features were extracted by using three pre-trained convolutional neural networks (CNN) models which are VGG19, InceptionV3, and Resnet50. Eight machine learning approaches were used in the classification step and compared for model performance.ResultsThe results showed that the Artificial Neural Network (ANN) model achieved the best testing accuracy of 91.14%, using the deep features extracted from the VGG19 model from lower beak images. The results indicated that the deep features were more accurate than the traditional features in highlighting morphometric differences from the beak images of cephalopod species. In addition, the use of lower beaks of cephalopod species provided better results compared to the upper beaks, suggesting that the lower beaks possess more significant morphological differences between the studied cephalopod species. Future works should include more cephalopod species and sample size to enhance the identification accuracy and comprehensiveness of the developed model.

Vertebral heart size and cardiosternal contact evaluation in thoracic roentgenographs of the Nigerian indigenous dog

The aim of this cross-sectional prospective radiologic study was to determine reproducible biometric ratios for cardiac assessment in the indigenous dog. Thirty healthy male and female dogs were used for the study. Sixty right and left lateral thoracic projections of the dogs were acquired. Parameters in each radiograph were objectively evaluated, namely: cardiac long and short axes in right and left lateral views. Indices generated were the vertebral heart size and the cardiosternal contact (also known as intercostal heart size). The mean values of vertebral heart size (VHS) and intercostal heart size (IHS) were: 9.82±0.08/9.70±0.10 and 3.40±0.05/3.37±0.05 for the right and left lateral radiographs, respectively. Vertebral heart size correlated strongly, positively and significantly with cardiac long and short axes while IHS showed a high, positive and significant relationship with short axis but a moderately, positively significant association with long axis. The indices determined in the study are easy to use and allow for objective investigation of the canine heart. The results of this research are clinically relevant in the diagnosis and management of cardiac anomalies. Keywords: Diagnosis, Nigerian dogs, radiology, thoracic measurements

Computed tomography validated right ventricular mid-septal lead implantation using right ventricular angiography.

BackgroundRight ventricular (RV) mid‐septal pacing has been proposed as an alternative to RV apical pacing. Fluoroscopic and electrocardiogram criteria are unreliable for predicting the RV mid‐septal lead position. This study aimed to define the optimal RV mid‐septal pacing site using RV angiography.MethodsWe randomized patients undergoing pacemaker implantation (PPM) to the RV angiography‐guided group (Group A) or conventional fluoroscopy‐guided group (Group F). In Group A, we performed an angiogram in right anterior oblique (RAO 30°), left anterior oblique (LAO 40°), and left lateral (LL) views. We made a 5‐segment grid in RAO 30° and LL views and a 3‐segment grid in LAO 40° on the angiographic silhouette to define the lead position. Computed tomography (CT) was used to validate the lead tip position in both groups.ResultsWe enrolled 53 patients (Group A: 26, Group F: 27) with a mean age of 55.9 ± 12.2 years. CT images validated the lead position in the mid‐septum (Group A, 23 [88.5%]; Group F, 11 [40.7%], P = .0003) and anteroseptal (Group A, 3 [11.5%]; Group F, 5 [18.5%], P = .24). In Group F, the lead was in the anterior wall in 9 patients (33.3%) and the right ventricular outflow tract in 2 (7.4%) patients and none in these two positions in Group A. The lead tip in segment one on the angiographic 5‐segment grid in RAO 30° and LL views indicated a mid‐septal lead position on CT.ConclusionsRV angiography is safe and may be used to confirm the mid‐septal lead position during PPM.

Is There a Difference in Whole Body Standing Posture in Women With Urinary Incontinence Based on the Presence of Myofascial Dysfunction in the Pelvic Floor Muscles?

The purpose of this study was to assess the prevalence of postural changes in women who had urinary incontinence (UI) with myofascial dysfunction (MD) and women who had UI without MD in the pelvic floor muscles (PFM). A cross-sectional study was performed with 234 women who had UI and were at least 18years old at the urogynecology outpatient clinic of a tertiary academic hospital. The International Consultation on Incontinence Questionnaire-Short Form and the International Consultation on Incontinence Questionnaire-Overactive Bladder were used to collect urinary data. Standing postural assessment was performed using photogrammetry in anterior, posterior, and right and left lateral views and was analyzed with Postural Assessment Software. MD was defined as pain of any intensity during palpation of the PFM, and the strength of these muscles was evaluated using the Modified Oxford Scale. The prevalence of MD in women with UI was 51.7% (121/234). Women with MD had significantly smaller angles in the horizontal alignment of the pelvis in the right-side view (mean [SD] = -11.9 [6.9] degrees and -9.6 [7.1] degrees), left-side view (-13.6 [6] degrees and -11.5 [6.6] degrees), and vertical alignment of the body in the left-side view (3 [1.5] degrees and 3.4 [1.5] degrees), showing anterior pelvic tilt and posterior displacement of the body. Women with UI and MD had greater anterior pelvic tilt and posterior displacement of the body than women without dysfunction. This study informs physical therapists and other health care professionals about the prevalence of MD in the pelvic floor muscles of women with UI and highlights the need to rule out MD, because it appears to be a concomitant impairment in women who self-report UI. During a postural screen, health care professionals should look for anterior pelvic tilt relative to horizon when evaluating posture in women with UI and MD. The findings of postural changes in women with MD and UI may influence the PFM assessment. Women with involuntary urinary loss, pain, and stiffness in the pelvic area may show changes in posture associated with this condition.
