Vesicouterine fistulae, despite being infrequent, are no longer a rare diagnosis and are most commonly secondary to lower segment caesarean section. With patient history and selected investigations diagnosis is relatively easy. The surgical repair of these fistulae is standard treatment, especially with delayed fistulae with achievement of total continence, and complete resolution of cyclic haematuria. Meticulous practice of obstetric and surgical principles during caesarean section can prevent the formation of these fistulae.
Ureteroscopic lithotripsy can be performed on day care basis under sedoanalgesia which is fairly tolerated by the patients with unremarkable complications and difficulty.
Purpose: This study was done to ascertain gender dif
ferences in trained swimmers between their Critical S
wim Speed (CSS). Certain metabolic responses, imme
diately after 400 meters free style swimming (FSS), w
ith maximum effort, were also studied.
Methods: The analysis was conducted in trained swi
mmers between 12- 18 years age. Height, weight, bod
y fat quantity were estimated using standard techniqu
es. CSS was measured for each swimmer. Blood samp
les were taken within two minutes of 400 meters FSS,
with maximum efforts. The blood creatinine, lactic ac
id, serum calcium, serum urea and serum urea nitroge
n were estimated using standard laboratory methods.
Results: With the maximal effort of 400 meters FSS,
values of hematological variables for both sexes were
found to increase many folds than reference values. Si
gnificant (p<0.05) gender differences were observed
in CSS and blood creatinine. The positive significant
(p<0.05) correlation was found between CSS and heig
ht in the swimmers. For trained male swimmers signif
icant positive correlations among CSS, blood urea an
d serum urea nitrogen were found.
Conclusions: This study reflects metabolic status of b
oth trained male and female swimmers, after their full
efforts. Besides blood creatinine no significant differe
nces were observed in them. So it may conclude that e
ffective physical training minimizes the metabolic de
mands during their full efforts and gender differences
could be overcome.
Introduction: Breathing involves respiratory
muscle activities by recruiting motor units. The
obstructive and restrictive lung diseases were
categorized based on spirometric measurement.
Measurement of respiratory muscle function is
important in the diagnosis of respiratory disease or
dysfunction.
Purpose: This study focuses on the involvement of
motor units in diaphragm, external intercostals and
latissimus dorsi muscles during voluntary
contractions in young boys having obstructive and
restrictive lung diseases.
Materials and methods: Fifty eight young male
(14-20 years) were participated and they were
grouped into three (normal, restrictive and
obstructive) according to their lung condition
measured by Spirometry. One way ANOVA was
done to understand the significant differences
between the muscles of three groups. Involvement
of motor unit was shown by plotting the Line
diagrams. Mean and standard deviation along with
one way ANOVA were calculated in case of three
respiratory muscles (External intercostals,
Diaphragm, and latissimus dorsi) for three groups.
Results: No significant differences were found
among three groups during performing Forced vital
capacity (FVC), Slow vital capacity (SVC),
Maximum voluntary ventilation (MVV), and
Minute ventilation (MV). Line diagram shows that
during FVC, SVC, and MVV responses of different
muscles are higher in three different groups except
during MV.
Conclusion: This study states that motor unit
involvement is different in the case of three
different conditions. It can be concluded that
restrictive and obstructive diseases might not be
interpreted on the basis of only spirometric
measurements in static and dynamic lung
conditions. Motor unit activation and responses of
major respiratory muscles were important
determinants during spirometric measurements
The primary objective of this study is to establish a relationship between maximum voluntary contraction (MVC) and motor unit activity (RMS) during forced and normal respiration. Fifty-nine male athletes between the ages of 15-20 years participated. During forceful and regular respiration surface electromyography (sEMG) was performed on participants' external intercostal, diaphragm, and latissimus dorsi muscles. The raw sEMG recordings were filtered to compute MVC and RMS. Pearson's correlation test revealed a substantial positive association between MVC and RMS for all muscles (p<0.05). A simple linear regression model was used to establish the best feasible equation based on correlation. MVC shows interconnection with RMS during both respiration in both groups, indicating variations in motor unit activity during respiration may contribute to a muscle's maximum ability to generate force. In these situations, 'y=b+mx' can be used to quantitatively express the link between MVC and RMS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
