Some of these infections can develop into more serious abscesses that require incision with a scalpel, drainage of the abscess, and antibiotics.

Some recent research suggests that the overuse of antibiotics in the raising of livestock for meat consumption is contributing to outbreaks of bacterial infections such as C. difficile.

Some antibiotics use primary metabolites as precursors, such as actinomycin which is created from the primary metabolite, tryptophan.

Some 60 % of cases are preceded by a dental surgical procedure ( that involve the bone ), and it has been suggested that bisphosphonate treatment should be postponed until after any dental work to eliminate potential sites of infection ( the use of antibiotics may otherwise be indicated prior to any surgery ).

Some people with A-T need additional immunizations ( especially with pneumonia and influenza vaccines ), antibiotics to provide protection ( prophylaxis ) from infections, and / or infusions of immunoglobulins ( gamma globulin ).

Some species produce metabolites similar to antibiotics: bacteriocins of the corynecin-linocin type, antitumor agents, etc.

Some people with balance disorders or adverse reactions to antibiotics suffer from bilateral vestibular damage ( BVD ).

* Some medicines: tetracycline antibiotics, sulfonamides, amiodarone, quinolones

Some patients have responded to antibiotics.

Some churches require more.

Some established jurisdictions require adherence to design and historic preservation guidelines.

Some opcodes require one or more operands as part of the instruction, and most assemblers can take labels and symbols as operands to represent addresses and constants, instead of hard coding them into the program.

Some instances of exploring these " nearby " nodes require traversing up to 2 × log ( n ) links ( particularly when moving from the rightmost leaf of the root's left subtree to the leftmost leaf of the root's right subtree ).

Some contact adhesives require as long as 24 hours to dry before the surfaces are to be held together.

Some authors require in addition that μ ( C ) < ∞ for every compact set C. If a Borel measure μ is both inner regular and outer regular, it is called a regular Borel measure.

Some forms of Islamic law, as in Saudi Arabia, may require capital punishment, but there is great variation within Islamic nations as to actual capital punishment.

Some cities such as Seattle and San Francisco require food and yard waste to be sorted for composting.

Some casinos require all players to make a minimum Pass or Don't Pass bet whether they are currently shooting or not.

* Some such countries do not require tourist visas of citizens of other Commonwealth countries.

Some other cash registers require a numeric password or physical key to be used when attempting to open the till.

Some undergraduate courses require a team of 2 to 5 students to design, implement, and test a simple CPU in a FPGA in a single 15 week semester.

Some shotgun sports, such as skeet, use crossing targets presented in a narrow range of distance, and only require one level of choke.

Some of the roads in more rural area are rough and unpaved, and require a four-wheel drive vehicles.

Some holes may require a throw from a Drop Zone.

Some players will use mid-ranges as drivers, and there are tournaments that require players to use only mid-range discs.

Some digital synthesizers now exist in the form of " softsynth " software that synthesizes sound using conventional PC hardware, though they require careful programming and a fast CPU to get the same latency response as their dedicated equivalents.

Some programs offer programs with two pre-professional years followed by four professional years, while others require a four year undergraduate / bachelor's degree.

Some Protestant communities including most Lutheran churches practice closed communion and require catechetical instruction for all people before receiving the Eucharist.

Some authors also require the domain of the Euclidean function be the entire ring R ; this can always be accommodated by adding 1 to the values at all nonzero elements, and defining the function to be 0 at the zero element of R, but the result is somewhat awkward in the case of K. The definition is sometimes generalized by allowing the Euclidean function to take its values in any well-ordered set ; this weakening does not affect the most important implications of the Euclidean property.

Some definitions of epilepsy require that seizures be recurrent and unprovoked, but others require only a single seizure combined with brain alterations which increase the chance of future seizures.

Some patients, however, require polypharmacy, the use of two or more anticonvulsants.

Some of these risks may be self-insurable, while most will require the purchase of an insurance contract.
