Successful treatment of lower urinary tract infections with oral fosfomycin: a report of three cases

Infections due to multidrug-resistant organisms continue to increase, and therapeutic options remain scarce. Given this challenge, it has become necessary to use older antimicrobials for treatment of these pathogens. We report three patients with lower urinary tract infections caused by Klebsiella pneumoniae carbapenemase (KPC)-producing Klebsiella pneumoniae who were successfully treated with a seven-day course of oral fosfomycin monotherapy.

Dirofilariasis involving the oral cavity: report of the first case from South America

Oral dirofilariasis is very rare with non-specific clinical manifestations. Here, we report the case of a 65-year-old South American woman with a submucosal nodule on her right buccal mucosa. The nodule was slightly tender and painful. Differential diagnoses included mesenchymal (lipoma or fibrolipoma, solitary fibrous tumor, and neurofibroma) or glandular benign tumors (pleomorphic adenoma) with secondary infections. We performed excisional biopsy. A histopathological examination revealed a dense fibrous capsule and a single female filarial worm showing double uterus appearance, neural plaque, well-developed musculature and intestinal apparatus. Dirofilariasis was diagnosed, and the patient was followed-up for 12 months without recurrence.

Prevalence of hypovitaminosis D and its association with oral lesions in HIV-infected Brazilian adults

Abstract: INTRODUCTION: This study assessed the prevalence of hypovitaminosis D and its association with oral candidiasis and clinical parameters of periodontitis (CPP) in HIV-infected patients. METHODS: Periodontal examinations for the 113 HIV-infected patients were recorded using the Community Periodontal Index. A cytological smear from the lateral borders of the tongue was performed to evaluate candidiasis. RESULTS: The frequency of hypovitaminosis D was 23.9%. In multivariate analysis, only the duration of exposure to HIV was associated with CPP [OR 4.72 (95% CI: 0.97-23.00)]. CONCLUSIONS: The prevalence of hypovitaminosis D was 23.9% and was not related with oral candidiasis or CPP.

Chemotherapy versus best supportive care in stage IV non-small cell lung cancer, non metastatic to the brain

Stage IV non-small cell lung cancer is a fatal disease, with a median survival of 14 months. Systemic chemotherapy is the most common approach. However the impact in overall survival and quality of life still a controversy. OBJECTIVES: To determine differences in overall survival and quality of life among patients with stage IV non-small cell lung cancer non-metastatic to the brain treated with best supportive care versus systemic chemotherapy. PATIENTS: From February 1990 through December 1995, 78 eligible patients were admitted with the diagnosis of stage IV non-small cell lung cancer . Patients were divided in 2 groups: Group A (n=31 -- treated with best supportive care ), and Group B (n=47 -- treated with systemic chemotherapy). RESULTS: The median survival time was 23 weeks (range 5 -- 153 weeks) in Group A and 55 weeks (range 7.4 -- 213 weeks) in Group B (p=0.0018). In both groups, the incidence of admission for IV antibiotics and need of blood transfusions were similar. Patients receiving systemic chemotherapy were also stratified into those receiving mytomycin, vinblastin, and cisplatinum, n=25 and those receiving other combination regimens (platinum derivatives associated with other drugs, n=22). Patients receiving mytomycin, vinblastin, and cisplatinum, n=25 had a higher incidence of febrile neutropenia and had their cycles delayed for longer periods of time than the other group. These patients also had a shorter median survival time (51 versus 66 weeks, p=0.005). CONCLUSION: In patients with stage IV non-small cell lung cancer, non-metastatic to the brain, chemotherapy significantly increases survival compared with best supportive care.

Oral manifestations of Albright hereditary Osteodystrophy: a case report

Albright hereditary osteodystrophy is a hereditary metabolic disorder of dominant autosomal etiology that is commonly characterized by short stature, round face, small metacarpus and metatarsus, mental retardation, osteoporosis, subcutaneous calcification, variable hypocalcemia, and hyperphosphatemia. In this study, we report a clinical case of a 17-year-old woman with Albright hereditary osteodystrophy, and we discuss her clinical, radiographic, and laboratory test characteristics together with the oral manifestations, and we correlate them with the characteristics found in the literature. We also discuss the odontological management of treatment of related periodontal disease and planning for corrections of related malocclusions.

Relation between oral health and socioeconomic variables among schoolchildren aged 12 in the City of Manaus - AM

Studies have shown that the age of 12 was determined as the age of global monitoring of caries for international comparisons and monitoring of disease trends. The aimed was to evaluate the prevalence of dental caries, fluorosis and periodontal condition and their relation with socioeconomic factors among schoolchildren aged twelve in the city of Manaus, AM. This study with a probabilistic sample of 661 children was conducted, 609 from public and 52 from private schools, in 2008. Dental caries, periodontal condition and dental fluorosis were evaluated. In order to obtain the socioeconomic classification of each child (high, upper middle, middle, lower middle, low and lower low socioeconomic classes), the guardians were given a questionnaire. The mean decayed teeth, missing teeth, and filled teeth (DMFT) found at age twelve was 1.89. It was observed that the presence of dental calculus was the most severe periodontal condition detected in 39.48%. In relation to dental fluorosis, there was a low prevalence in the children examined, i.e., the more pronounced lines of opacity only occasionally merge, forming small white areas. The study showed a significant association of 5% among social class with dental caries and periodontal condition. In schoolchildren of Manaus there are low mean of DMFT and fluorosis, but a high occurrence of gingival bleeding.

Emprego de altas doses de amiodarona via oral na reversão da fibrilação atrial no pós-operatório de cirurgia cardíaca

OBJETIVO: Relatar a experiência no emprego de altas doses de amiodarona via oral (1800mg/d) na reversão da fibrilação atrial (FA) em pacientes submetidos à cirurgia cardíaca. MÉTODOS: Analisados, retrospectivamente, 80 pacientes que apresentaram FA no pós operatório de cirurgia cardíaca, constituindo 2 grupos: grupo A com 28 pacientes em uso de amiodarona e grupo B recebendo digital, sendo que este grupo foi subdividido no grupo C com 21 pacientes onde foi associada amiodarona, quando não houvesse reversão da arritmia em 48h. As diferenças foram consideradas significativas para um valor de P<0,05. RESULTADOS: A FA esteve presente em 19,4% dos pacientes operados, com predomínio no sexo masculino e entre 60-69 anos. No grupo A, a reversão ocorreu em 78,6% dos casos, grupo B, o digital obteve sucesso em 60% das vezes e no grupo C, a taxa de sucesso foi de 90%. CONCLUSÃO: O uso de altas doses de amiodarona via oral, isolada ou em combinação com digital pode ser segura e eficaz no tratamento da FA em pós operatório de cirurgia cardíaca.

Use of oral antihypertensive medication preceding blood pressure elevation in hospitalized patients

OBJECTIVE: To evaluate the frequency of oral antihypertensive medication preceding the increase in blood pressure in patients in a university hospital, the drug of choice, and the maintained use of antihypertensive medication. METHODS: Data from January to June 1997 from the University Hospital Professor Edgard Santos Pharmacy concerning the prescriptions of all inpatients were used. Variables included in the analysis were: antihypertensive medication prescription preceding increase in blood pressure, type of antihypertensive medication, gender, clinical or surgical wards, and the presence of maintained antihypertensive medication. RESULTS: The hospital admitted 2,532 patients, 1,468 in surgical wards and 818 in medical wards. Antihypertensive medication prescription preceding pressure increase was observed in 578 patients (22.8%). Nifedipine was used in 553 (95.7%) and captopril in 25 (4.3%). In 50.7% of patients, prescription of antihypertensive medication was not associated with maintained antihypertensive medication. Prescription of antihypertensive drugs preceding elevation of blood pressure was significantly (p<0.001) more frequent on the surgical floor (27.5%; 405/1468) than on the medical floor (14.3%; 117/818). The frequency of prescription of antihypertensive drugs preceding elevation of blood pressure without maintained antihypertensive drugs and the ratio between the number of prescriptions of nifedipine and captopril were greater in surgical wards. CONCLUSION: The use of antihypertensive medication, preceding elevation of blood pressure (22.8%) observed in admitted patients is not supported by scientific evidence. The high frequency of this practice may be even greater in nonuniversity hospitals.

Endocardite de Libmann-Sacks e anticoagulação oral

Paciente de 34 anos, com lúpus eritematoso sistêmico e síndrome de anticorpo antifosfolípide secundária, evoluiu com crises convulsivas, parcialmente controladas com anticonvulsivante, e ausculta de sopro cardíaco, cuja propedêutica mostrou a presença de vegetação em valva mitral. Diante do diagnóstico de endocardite de Libman-Sacks foi iniciada terapia com warfarina sódica, e após seis meses de anticoagulação oral, a paciente apresentava controle total das crises convulsivas e desaparecimento da vegetação valvar ao ecocardiograma. São discutidas a ocorrência da endocardite de Libman-Sacks no lúpus eritematoso sistêmico, sua associação com a síndrome de anticorpo antifosfolípide e a terapêutica anticoagulante, e feita uma revisão da literatura.

Controle do tempo de protrombina em sangue capilar e venoso em pacientes com anticoagulação oral: correlação e concordância

FUNDAMENTO: O uso de anticoagulantes orais (ACO) é comum na prática cardiológica, tendo como principais indicações a fibrilação atrial e próteses valvares. Os pacientes em uso de ACO necessitam de controle freqüente do tempo de protrombina (TP). Novos sistemas portáteis de monitorização, para medida do tempo de protrombina, sem necessidade da coleta de sangue por venopunção, facilitam a rotina desses pacientes. OBJETIVO: Comparar as medidas do TP realizadas pelo sistema Coaguchek S®, em sangue capilar, com o método padrão em sangue venoso. MÉTODOS: Cento e vinte e sete pacientes em acompanhamento no ambulatório de anticoagulação do Instituto de Cardiologia foram submetidos ao método convencional e coleta de sangue capilar da polpa digital para medida com o sistema Coaguchek S®. RESULTADOS: A idade foi de 58±14 anos, 90% eram brancos. As indicações de ACO foram fibrilação atrial 49,6% e próteses valvares 37,0%. O coeficiente de correlação r s foi 0,90 (p<0,0001; IC:95% 0,87-0,93) entre o sistema em estudo e o controle. A medida de concordância entre pacientes com INR <2, entre 2 e 3,5 e > 3,5 foi de Kappa 73,5%. O sistema Coaguchek S® superestimou o INR em 0,15±0,85 unidades. Valores acima de 3,5 unidades de INR mostram discrepância importante entre as duas técnicas. CONCLUSÕES: O sistema Coaguchek S® mostrou boa correlação e bom grau de concordância quando comparado com o controle, com resultados menores que 4. Porém, valores de INR acima de 3,5 ainda necessitam de confirmação com o método padrão.
