An Interactive Computer Kiosk Module for the Treatment of Recurrent Uncomplicated Cystitis in Women

OBJECTIVE: To validate and implement a computer module for the management of uncomplicated urinary tract infections (UTI). PARTICIPANTS: Women age 18 to 64 years, with a previous UTI, voiding symptoms, and absence of complicating features (comorbidities, vaginal discharge, back pain, emesis, and fever/chills). MEASUREMENTS: The computer module was validated against clinician diagnosis and urine culture. Following validation, the module was implemented in the urgent care clinic as a management option for women with suspected UTI; computer-directed therapy (CDT)-eligible women received antibiotic treatment without a clinician examination. Patient satisfaction with the module and return visits for UTI-related complaints were assessed. RESULTS: In the validation study, 18 of 68 women (26%) were CDT-eligible. Clinicians diagnosed 17/18 CDT-eligible women with uncomplicated UTI. Sixty-seven percent of CDT-eligible women had a positive urine culture. Since implementation, 162 women have accessed the module, and 35% have received CDT. Ninety-eight percent (95% confidence interval: 95% to 100%) found the program easy to use and 95% (89% to 100%) would recommend it to friends/family. Two (4%) CDT-treated women had a return visit to our institution for a UTI-related illness within 2 weeks. CONCLUSIONS: A computer module accurately identifies women with culture-confirmed, uncomplicated UTIs. Patients are highly satisfied with the module

Achado de bactérias selecionadas em crianças de Trinidad com doença amigdaliana crônica Selected bacterial recovery in Trinidadian children with chronic tonsillar disease

Faringoamigdalite na população pediátrica é largamente tratada com antibióticos. OBJETIVO: Estudar a microflora presente na superfície e no núcleo de amígdalas após adenoamigdalectomia eletiva em crianças. MÉTODO: Amígdalas de 102 crianças de Trinidad foram prospectivamente estudadas por meio de culturas e identificações bacteriológicas feitas a partir de amostras das superfícies e núcleos de suas amígdalas entre 2005-2006. RESULTADOS: A partir de 360 amígdalas, foram isolados Streptococcus spp. (51,3%), Staphylococcus spp. (42,3%) e Gram-Negativos (6,4%). A identificação de estafilococos e estreptococos tanto na superfície quanto no núcleo foi semelhante (p>0,05). Encontramos mais (p<0,001) Streptococcus spp. nas superfícies (82,2%) do que nos núcleos (63,3%); a prevalência de estreptococos alfa-hemolíticos foi maior (p<0,001) do que aquela de estreptococos beta-hemolíticos nas superfícies (74,4% vs. 18,6%) do que nos núcleos (58,9% vs. 13,7%). Não houve concordância entre superfícies e núcleos com relação a estreptococos (p<0,0004) e estreptococos alfa-hemolíticos (p<0,007). Estreptococos beta-hemolíticos foram mais identificados (p<0,05) em crianças dentre 6-16 anos do que naquelas entre 1-5 anos de idade (31% e 23,8% vs 12,5% e 8%). A prevalência de S. pyogenes na superfície e no núcleo foi de (84,6% vs 70%) e (50,0% vs 25,0%) em crianças de maior faixa etária e crianças mais novas, respectivamente. Klebsiella spp. (6,6%, 2,2%), Proteus (4,4%, 4,4%) e Pseudomonas (4,4 %, 1,1%) cresceram nas superfícies e núcleos, respectivamente. CONCLUSÃO: As superfícies amigdalianas tinham mais estreptococos e estreptococos hemolíticos do que seus núcleos. Crianças mais velhas tiveram mais estreptococos beta-hemolíticos, e são altamente colonizadoras de S. pyogenes. Sugerimos estudos que investiguem os mecanismos de aderência estreptocócica em crianças de Trinidad.<br>Pharyngotonsillitis in children is widely treated with antibiotics. AIM: To examine tonsil surface and core microflora following elective adenotonsillectomy in children. METHODS: Tonsils of 102 Trinidadian children were prospectively examined for surface and core bacteriological culture and identification between 2005-2006. RESULTS: Tonsils (360) yielded 800 isolates of Streptococcus spp. (51.3%), Staphylococcus spp. (42.3%) and Gram-negative genera (6.4%). Surface and core recovery of staphylococci and streptococci were similar (p>0.05). More (p<0.001) surfaces (82.2%) than cores (63.3%) grew Streptococcus spp.; &#945;-haemolytic Streptococcus prevalence was higher (p<0.001) than ß-haemolytic Streptococcus on surfaces (74.4% vs. 18.6%) than cores (58.9% vs. 13.7%). Surfaces and cores were not concordant for streptococci (p<0.0004) and &#945;-haemolytic Streptococcus (p<0.007). Surface and core ß-haemolytic Streptococcus yield was higher (p<0.05) in 6-16 than 1-5 year olds (31% and 23.8% vs 12.5% and 8%). S. pyogenes surface and core prevalence was (84.6% vs 70%) and (50.0% vs 25.0%) in older and younger children respectively. Klebsiella spp. (6.6 %, 2.2%), Proteus (4.4%, 4.4%) and Pseudomonas (4.4 %, 1.1%) grew on surfaces and cores respectively. CONCLUSION: Tonsil surfaces yield higher surface than core carriage for streptococci overall and for &#945; haemolytic streptococci. Older children grow more &#946;-haemolytic streptococci and are high colonizers of S. pyogenes. Studies probing the mechanisms of streptococcal adhesions in Trinidadian children are suggested
