Implications of the simultaneous presence of metronidazole-susceptible and -resistant Helicobacter pylori colonies within a single biopsy specimen

Abstract: This study examined whether the simultaneous presence of metronidazole-susceptible and -resistant Helicobacter pylori colonies in a single biopsy specimen is caused by a multiple strain infection with a susceptible and a resistant strain or by two subpopulations within a single strain. Single colonies obtained from seven biopsy specimens known to harbour both susceptible and resistant Helicobacter pylori were fingerprinted by restricted fragment length polymorphism typing of the ureC gene and by the random amplified polymorphic DNA procedure. Metronidazole susceptibility was determined by the E test. The results indicated that the occurrence of metronidazole-resistant and metronidazole-susceptible bacteria within a single biopsy does not imply the presence of a multiple strain infection with one resistant and one sensitive strain.

The abductor digiti minimi muscle flap: An adjunct in the treatment of metacarpal osteomyelitis

Abstract: The abductor digiti minimi muscle has a constant 1 to 1.5 cm neurovascular pedicle that arises from the ulnar artery and nerve within Guyon's canal. We have successfully used the abductor digiti minimi as a pedicle transfer as an adjunct in the treatment of chronic osteomyelitis of the small and ring finger metacarpal shafts.

Psychological sequelae of closed head injury: Time to redress the imbalance

Abstract: In the past two decades we have seen a plethora of studies examining the psychological sequelae of closed head injury. This in itself represented an important step, where previously the emphasis had been on documenting survival statistics and residual physical disability. The earlier psychological studies, such as those conducted by Brooks and his colleagues [1] and Levin and his colleagues [2], focused largely on cognitive functions, including intelligence, language, memory and perception, following the localizationist models of neuropsychology which predominated at the time.

Correlation of findings in clinical and high resolution ultrasonography examinations of the painful shoulder.

Abstract: High resolution ultrasonography is a non-painful and non-invasive imaging technique which is useful for the assessment of shoulder pain causes, as clinical examination often does not allow an exact diagnosis. The aim of this study was to compare the findings of clinical examination and high resolution ultrasonography in patients presenting with painful shoulder.Non-interventional observational study of 100 adult patients suffering from unilateral shoulder pain. Exclusion criteria were shoulder fractures, prior shoulder joint surgery and shoulder injections in the past month. The physicians performing the most common clinical shoulder examinations were blinded to the results of the high resolution ultrasonography and vice versa.In order to detect pathology of the m. supraspinatus tendon, the Hawkins and Kennedy impingement test showed the highest sensitivity (0.86) whereas the Jobe supraspinatus test showed the highest specificity (0.55). To identify m. subscapularis tendon pathology the Gerber lift off test showed a sensitivity of 1, whereas the belly press test showed the higher specificity (0.72). The infraspinatus test showed a high sensitivity (0.90) and specificity (0.74). All AC tests (painful arc II(a), AC joint tenderness(b), cross body adduction stress test(c)) showed high specificities ((a)0.96, (b)0.99, (c)0.96). Evaluating the long biceps tendon, the palm up test showed the highest sensitivity (0.47) and the Yergason test the highest specificity (0.88).Knowledge of sensitivity and specificity of various clinical tests is important for the interpretation of clinical examination test results. High resolution ultrasonography is needed in most cases to establish a clear diagnosis.
