ABSTRACT

High-resolution ultrasound has gained increasing popularity as an aid in the diagnosis of rotator cuff pathology. With the advent of portable machines; ultrasound has become accessible to clinicians. Aim: This study was conducted to evaluate the accuracy and reliability of ultrasound in diagnosing rotator cuff tears by a shoulder surgeon and comparing their ability to that of a musculoskeletal radiologist. Materials and Methods: Seventy patients undergoing shoulder arthroscopy for rotator cuff pathology underwent preoperative ultrasonography (US). All patients were of similar demographics and pathology. The surgeon used a Sonosite Micromax portable ultrasound machine with a 10-MHz high frequency linear array transducer and the radiologist used a 9-12 MHz linear array probe on a Siemens Antares machine. Arthroscopic diagnosis was the reference standard to which ultrasound findings were compared. Results: The sensitivity in detecting full thickness tears was similar for both the surgeon (92) and the radiologist (94). The radiologist had 100sensitivity in diagnosing partial thickness tears; compared to 85.7for the surgeon. The specificity for the surgeon was 94and 85for the radiologist. Discussion: Our study shows that the surgeons are capable of diagnosing rotator cuff tears with the use of high-resolution portable ultrasound in the outpatient setting. Conclusion: Office ultrasound; by a trained clinician; is a powerful diagnostic tool in diagnosing rotator cuff tears and can be used effectively in running one-stop shoulder clinics

ABSTRACT

Debido a la importancia de la hemoglobina como indicador nutricional, así como su papel en la oxigenación de los tejidos, fue realizado este estudio con el objetivo de observar la existencia o no de alteraciones en los niveles de hemoglobina de individuos fumadores donantes de sangre, de tal manera que dichas alteraciones causadas por el cigarrillo sean consideradas, al evaluar el estado de salud de un individuo fumador, así como en el diagnóstico de las patologías asociadas. Fueron seleccionados 121 varones, aparentemente sanos, fumadores y no fumadores, entre 20 y 60 años de edad, donantes de cinco bancos de sangre de Asunción, Paraguay. Los niveles promedios de hemoglobina en fumadores fueron 150 ± 8 g/L y en los no fumadores 148 ± 9 g/L, no siendo la diferencia significativa (p>0.05); sin embargo dentro del grupo de fumadores, la diferencia fue significativamente mayor en aquellos que fumaban de 11 a 20 cigarrillos /día (152 ± 9 g/L) que en aquellos que fumaban de 1 a 10 cigarrillos /día (148 ± 7 g/L) (p<0.05). Por lo tanto, el nivel medio de hemoglobina se incrementa con el número de cigarrillos consumidos por día. El coeficiente de correlación hallado fue de 0,38 con un nivel de confianza del 95%. Debemos seguir investigando, en nuestra población, la influencia del cigarrillo sobre los parámetros hematológicos, y el efecto que producen dichas alteraciones en el estado de salud de los fumadores.


Due to the important role haemoglobin plays as nutritional marker and in tissue oxygenation, this study was carried out to determine if there are alterations in haemoglobin levels of smoking blood donors. In this way, these alterations caused by cigarettes should be considered when the health status of smoking men is evaluated, as well as in the diagnosis of associated pathologies. One hundred and twenty one male individuals were selected for this study. They were apparently healthy, smoking and non­smoking men, between 20 and 60 years old, blood donors from five blood banks in Asunción, Paraguay. The mean haemoglobin level in smokers was 150 ± 8 g/L and in non­smokers 148 ± 9 g/L. The difference was not significant (p>0.05) but the difference was statistically greater in individuals smoking 11 to 20 cigarettes /day (152 ± 9 g/L) than in those who smoked 1 to 10 cigarettes /day (148 ± 7 g/L) (p<0.05). Thus, the mean value of haemoglobin increases with the number of cigarettes smoked per day. The correlation coefficient was 0.38 with a confidence interval of 95%. Further studies about the influence of cigarettes, the haematological parameters and the effect produced by alterations on the health status of smokers are necessary in this population.
