In veterinary medicine, streptomycin is the first-line antibiotic for use against gram negative bacteria in large animals (horses, cattle, sheep, etc.). It is commonly combined with procaine penicillin for intramuscular injection. Tularemia infections have been treated mostly with streptomycin.Streptomycin is traditionally given intramuscularly, and in many nations is only licensed to be administered intramuscularly, though in some regions the drug may also be administered intravenously. Pesticide
Streptomycin also is used as a pesticide, to combat the growth of bacteria beyond human applications. Streptomycin controls bacterial diseases of certain fruit, vegetables, seed, and ornamental crops. A major use is in the control of fireblight on apple and pear trees. As in medical applications, extensive use can be associated with the development of resistant strains. Streptomycin could potentially be used to control cyanobacterial blooms in ornamental ponds and aquaria. While some antibacterial antibiotics are inhibitory to certain eukaryotes, this seems not to be the case for streptomycin, especially in the case of anti-fungal activity. Cell culture
Streptomycin, in combination with penicillin, is used in a standard antibiotic cocktail to prevent bacterial infection in cell culture. Protein purification
When purifying protein from a biological extract, streptomycin sulfate is sometimes added as a means of removing nucleic acids. Since it binds to ribosomes and precipitates out of solution, it serves as a method for removing rRNA, mRNA, and even DNA if the extract is from a prokaryote. Side effects
The most concerning side effects, as with other aminoglycosides, are kidney toxicity and ear toxicity. Transient or permanent deafness may result.
Treatment may involve surgery, radiotherapy, or chemotherapy, alone or in combination.Surgical Treatment
Surgical treatment may involve partial or full removal of the tumour. Neighbouring tissues and structures may or may not be removed, depending on their involvement in the tumour’s structure and spread. Full removal of the larynx may be necessary in some cases. Adjunct Treatment
Adjunct treatment, most commonly the administration of chemotherapy or radiotherapy, may be necessary. Chemotherapy or radiotherapy may be necessary singly, in combination with each other, or in combination with surgery. Adjunct treatment may be necessary prior to surgical treatment, alongside surgical treatment, or after surgical treatment. Clinical decision-making can be difficult in circumstances where the patient is unable to access necessary adjunct treatment. Multi-Disciplinary Treatment
Often, successful treatment of and recovery from laryngeal cancer will involve expertise outside of the realms of surgery or oncology. Physical therapists, occupational therapists, speech therapists, psychiatrists, psychologists, oral/maxillofacial surgeons,  dentists, neurologists, neurosurgeons, and endocrinologists may all become involved in the care of patients with laryngeal cancer. Epidemiology
Incidence is five in 100,000 (12,500 new cases per year) in the US. The American Cancer Society estimated that 9,510 men and women (7,700 men and 1,810 women) would be diagnosed with and 3,740 men and women would die of laryngeal cancer in 2006.According to the GLOBOCAN 2018 estimates of cancer incidence and mortality produced by the International Agency for Research on Cancer, there were 177,422 new cases of laryngeal cancer worldwide in 2018 (1.0% of the global total.) Among worldwide cancer deaths, 94,771 (1.0%) were due to laryngeal cancer.
