With the emergence of fluoroquinolone-resistant MDR-TB and XDR-TB, treatment has become more difficult and costly, with favourable outcomes rarely exceeding 50 60%.
Even in selected cohorts of MDR-TB patients, with disease known to be susceptible to a fluoroquinolone and three or more injectable products, the proportion of patients experiencing favourable outcomes rarely exceeds 70% and mortality usually exceeds 15% [ 24].
Botryoid RMS is seen almost exclusively in the bladder or vagina of infants or young girls or the nasopharynx of slightly older children and has a particularly favourable prognosis, rarely metastasising and responding well to current treatment regimes.
Rarely has India enjoyed such favourable international prospects: of peace with Pakistan; of enhanced integration in the global economy; and of being accepted as an important world power.
However, not all low-grade prostate cancers with a Gleason score less than 7 follow an indolent course, and carcinomas with a Gleason score of 7 or higher, on the other hand, may (rarely) present with a rather favourable clinical behaviour.
Albeit this is rarely the case in operational systems, favourable capture conditions (resulting in low intra-class variance) are considered a fundamental premise for biometric cryptosystems.
Herbicidal control of large infestations of water hyacinth growing under favourable conditions has been attempted only rarely and even when enormous resources have been invested, as in Sudan, has had little effect.
However, in most countries, management and union are seldom inclined to resort to lockouts and strikes in an attempt to obtain favourable new contracts, and interest arbitration is thus rarely used.
There is an understanding (rarely made explicit) that large campaign donations buy political access and favourable consideration in policy development and legislation.
Furthermore, the secondary aggregates and the observation of aggregation in less favourable places (such as under the bright shelter, which was rarely observed) show that inter-attraction can, to a certain extent, outweigh individual preferences.
