Pollen types and levels of total phenolic compounds in propolis produced by Apis mellifera L. (Apidae) in an area of the Semiarid Region of Bahia, Brazil.

Twenty-two propolis samples produced by Apis mellifera L. in an area of the Semiarid region the the State of Bahia (Agreste of Alagoinhas), Brazil, were palynologically analyzed and quantified regarding their levels of total phenolic compounds. These samples were processed using the acetolysis technique with the changes suggested for use with propolis. We found 59 pollen types belonging to 19 families and 36 genera. The family Fabaceae was the most representative in this study with nine pollen types, followed by the family Asteraceae with seven types. The types Mikania and Mimosa pudica occurred in all samples analyzed. The types Mimosa pudica and Eucalyptus had frequency of occurrence above 50% in at least one sample. The highest similarity index (c. 72%) occurred between the samples ER1 and ER2, belonging to the municipality of Entre Rios. Samples from the municipality of Inhambupe displayed the highest (36.78±1.52 mg/g EqAG) and lowest (7.68 ± 2.58 mg/g EqAG) levels of total phenolic compounds. Through the Spearman Correlation Coefficient we noticed that there was a negative linear correlation between the types Mimosa pudica (rs = -0.0419) and Eucalyptus (rs = -0.7090) with the profile of the levels of total phenolic compounds of the samples.

Melipona scutellaris Geopropolis: Chemical Composition and Bioactivity.

Geopropolis has been used in traditional medicine for centuries. In this study, the botanical origin, physicochemical profile, and biological activities of geopropolis from Melipona scutellaris harvested during rainy and dry seasons were investigated. Palynological analysis identified over 50 pollen types, with Schinus terebinthifolius and Cecropia being the predominant types. The analytical results were in line with those reported in the literature. Rainy-season geopropolis exhibited higher total phenol and flavonoid content (determined using High Performance Liquid Chromatography-25.13% and 3.92%, respectively) compared to the dry season (19.30% and 2.09%); the major peaks (naringin, gallic acid, and catechin) were similar among samples. Antioxidant capacity was assessed via DPPH, reducing power, and ß-carotene/linoleic acid discoloration assays. Rainy-season samples displayed superior antioxidant activity across methods. Antimicrobial effects were determined using microdilution, while the impact on the cholinesterase enzyme was quantified using 5-thio-2-nitrobenzoic acid accumulation. Anti-inflammatory and antimutagenic activities were assessed through hyaluronidase enzyme inhibition and by utilizing Saccharomyces cerevisiae ATCC-20113 cells. Both samples exhibited anti-inflammatory and antimutagenic properties. Moreover, a significant inhibition of acetylcholinesterase was observed, with IC50 values of 0.35 µg/mL during the rainy season and 0.28 µg/mL during the dry season. Additionally, the geopropolis displayed antimicrobial activity, particularly against Staphylococcus aureus. These findings suggest the therapeutic potential of M. scutellaris geopropolis in the context of inflammatory, oxidative, and infectious diseases.

Characteristics of HIV-positive patients infected by vertical transmission, Campo Grande, MS, Brazil, 1993-2009.

OBJECTIVES: The goal of the authors was to determine the epidemiological and clinical characteristics of all HIV-positive children and adolescents infected by vertical transmission. METHODS: A descriptive, cross-sectional and retrospective study was conducted that included all HIV-positive patients infected by vertical transmission who attended the referral services of the municipality of Campo Grande from 1993 to 2009, and who used antiretrovirals (ARV). The data were collected from medical records after local institutional review board approval. RESULTS: 78 patients were included, and almost half of the living patients (75) in 2009 were 11-15 years of age. The average age at diagnosis was 38.8 months, treatment was most often initiated from 12 to 35 months of age, and HAART was the most common treatment. Most patients (51.3%) were hospitalised between one and five times, and the first regimen was not associated with hospitalisation (p=0.2). The majority of patients did not exhibit virological suppression at the last examination, and genotyping revealed the presence of resistance mutations. Failure of therapy was often the result of non-adherence to therapy. Five patients died, and the causes of death were pneumonia, sepsis, cerebral cryptococcosis and myocarditis. CONCLUSIONS: Despite the availability of drugs and appropriate laboratory tests, a significant number of paediatric patients were failing ARV therapy due to non-adherence. Further interventions to enhance adherence in this population are needed.

Evaluation of deoxyribonucleic acid toxicity induced by the radiopharmaceutical 99mTechnetium-Methylenediphosphonic acid and by stannous chloride in Wistar rats.

Radiopharmaceuticals are employed in patient diagnostics and disease treatments. Concerning the diagnosis aspect, technetium-99m (99mTc) is utilized to label radiopharmaceuticals for single photon computed emission tomography (SPECT) due to its physical and chemical characteristics. 99mTc fixation on pharmaceuticals depends on a reducing agent, stannous chloride (SnCl(2)) being the most widely-utilized. The genotoxic, clastogenic and anegenic properties of the 99mTc-MDP(methylene diphosphonate used for bone SPECT) and SnCl(2) were evaluated in Wistar rat blood cells using the Comet assay and micronucleus test. The experimental approach was to endovenously administer NaCl 0.9% (negative control), cyclophosphamide 50 mg/kg b.w. (positive control), SnCl(2) 500 μg/mL or 99mTc-MDP to animals and blood samples taken immediately before the injection, 3, and 24 h after (in the Comet assay) and 36 h after, for micronucleus test. The data showed that both SnCl(2) and 99mTc-MDP-induced deoxyribonucleic acid (DNA) strand breaks in rat total blood cells, suggesting genotoxic potential. The 99mTc-MDP was not able to induce a significant DNA strand breaks increase in in vivo assays. Taken together, the data presented here points to the formation of a complex between SnCl(2) in the radiopharmaceutical 99mTc-MDP, responsible for the decrease in cell damage, compared to both isolated chemical agents. These findings are important for the practice of nuclear medicine.

Self-Collection and Molecular Diagnosis for Detection of Human Papillomavirus: Why Incorporate It?

PURPOSE OF REVIEW: Cervical cancer, the third cause of death by cancer among Brazil's women, is associated with human papillomavirus (HPV) infection. In some countries of South America, North America, Europe, and Oceania, initial screening for HPV DNA and subsequent follow-up with HPV-positive patients using colposcopy and cytological testing are used as preventative measures. RECENT FINDINGS: For HPV DNA detection, it is necessary to obtain cervical cells by conventional clinical collection method or self-collection of the cells that flake off from the uterine cervix and vaginal canal. Self-collection has been shown to be a viable option for obtaining samples and is a less invasive method that is more accepted by women. Thus, it can potentially decrease the limitations of the conventional clinical collection methods. The efficiency of the self-collection method aligned with the implementation of HPV molecular testing, if adopted by public and private health care systems, may extend the reach of current cervical cancer prevention efforts. In addition, considering all phases from triage to treatment, this method may reduce health care costs and the time spent by patients and health care teams to conduct examinations and collect samples.

A case report of successful treatment of necrotizing fasciitis using negative pressure wound therapy.

RATIONALE: Necrotizing fasciitis is a destructive tissue infection with rapid progression and high mortality. Thus, it is necessary that high-performance dressings be introduced as possibilities of treatment. PATIENT CONCERNS: Female patient, 44 years of age, admitted to hospital unit complaining of lesion in the gluteal region and drainage of purulent secretion in large quantity followed by necrosis. DIAGNOSES: The diagnosis of necrotizing fasciitis was carried out with the computerized tomography examination result and its association with the patient's clinical condition. INTERVENTIONS: Initially, successive debridements were carried out in lower limbs as well as primary dressing with enzymatic debriding action until indication of negative pressure wound therapy, for the period of 2 weeks in the right lower limb and for 5 weeks in the left lower limb, with changes every 72 h. Dressing with saline gauze was used at the end of this therapy until hospital discharge. OUTCOMES: After the use of negative pressure wound therapy, we observed the presence of granulation tissue, superficialization and reduction of lesion extension. The patient presented good tolerance and absence of complications. LESSONS: Negative pressure wound therapy constituted a good option for the treatment of necrotizing fasciitis, despite the scarcity of protocols published on the subject.

Flaxleaf Fleabane Leaves (Conyza bonariensis), A New Functional Nonconventional Edible Plant?

This work aimed to investigate the phytochemical composition, nutritional value, antioxidant, antihemolytic, antihyperglycemic, and antiproliferative activities of flaxleaf fleabane (Conyza bonariensis) leaves. Different concentrations of water and ethanol (0:100, 25:75, 50:50, 75:25, and 100:0 v/v) were used in the extraction process and results showed that the hydroalcoholic extract (50:50 v/v) presented the highest total phenolics, ortho-diphenolics, Folin-Ciocalteu reducing capacity, FRAP, and Fe2+ chelating ability values. Flaxleaf fleabane leaves (FFL) contained 19.6 g/100 g of fibers and 26 g/100 g of proteins. Ellagic acid, procyanidin A2, caffeic, rosmarinic, gallic, and 2,5-dihydroxybenzoic acids were the main phenolics. This phenolic-rich extract inhibited the lipid oxidation of Wistar rat brain (IC50 = 863.0 mg GAE/L), inhibited α-glucosidase activity (IC50 = 435.4 µg/mL), protected human erythrocytes against mechanical hemolysis at different osmolarity conditions, and showed cytotoxic/antiproliferative effects against human ileocecal adenocarcinoma cells (HCT8; IC50 = 552.6 µg/mL) but no cytotoxicity toward noncancerous human lung fibroblast (IMR90). Overall, FFL showed potential to be explored by food companies to be a source of proteins, natural color substances, and phenolic compounds. PRACTICAL APPLICATION: Flaxleaf fleabane leaves (FFL) are usually burnt or partially given to cattle, without a proper utilization as a source of nutrients for human nutrition. Here, we studied the nutritional composition, phenolic composition, and toxicological aspects of FFL using different biological protocols. FFL was proven to be a rich source of proteins and dietary fibers and showed antioxidant activity measured by chemical and in vitro biological assays. Additionally, as it did protected human red cells and did not show cytotoxicity, we assume FFL has relative safety to be consumed as a nonconventional edible plant.

Non-polarized cytokine profile of a long-term non-progressor HIV infected patient.

The HIV-1 initial viral infection may present diverse clinical and laboratory course and lead to rapid, intermediate, or long-term progression. Among the group of non-progressors, the elite controllers are those who control the infection most effectively, in the absence of antiretroviral therapy (ART). In this paper, the TH1, TH2 and TH17 cytokines profiles are described, as well as clinical and laboratory aspects of an HIV-infected patient with undetectable viral load without antiretroviral therapy. Production of IL-6, IL-10, TNF-α, IFN-γ, and IL-17 was detected; in contrast IL-4 was identified. Host-related factors could help explain such a level of infection control, namely the differentiated modulation of the cellular immune response and a non-polarized cytokine response of the TH1 and TH2 profiles.

High vertical HIV transmission rate in the Midwest region of Brazil.

OBJECTIVES: To estimate vertical HIV transmission rate in a capital city of the Midwest region of Brazil and describe the factors related to transmission. METHODS: A descriptive epidemiological study based on the analysis of secondary data from the Notifiable Diseases Information System (SINAN). The analysis considered all HIV-infected pregnant women with delivery in Campo Grande-MS in the years 2007-2013 and their HIV-exposed infants. RESULTS: A total of 218 births of 176 HIV-infected pregnant women were identified during the study period, of which 187 infants were exposed and uninfected, 19 seroconverted, and 12 were still inconclusive in July 2015. Therefore, the overall vertical HIV transmission rate in the period was 8.7%. Most (71.6%) of HIV-infected pregnant women were less than 30 years at delivery, housewives (63.6%) and studied up to primary level (61.9%). Prenatal information was described in 75.3% of the notification forms and approximately 80% of pregnant women received antiretroviral prophylaxis. Among infants, 86.2% received prophylaxis, but little more than half received it during the whole period recommended by the Brazilian Ministry of Health. Among the exposed children, 11.3% were breastfed. CONCLUSION: The vertical HIV transmission rate has increased over the years and the recommended interventions have not been fully adopted. HIV-infected pregnant women need adequate prophylactic measures in prenatal, intrapartum and postpartum, requiring greater integration among health professionals.

Subcutaneous Implantable Cardioverter Defibrillator: Early Experience.

INTRODUCTION: The implantable cardioverter defibrillator had been increasing the survival of patients at high risk for sudden cardiac death. The subcutaneous implantable cardioverter defibrillator was developed to mitigate the complications inherent to lead placement into cardiovascular system. OBJECTIVE: To report the initial experience of 18 consecutive cases of subcutaneous implantable cardioverter defibrillator implantation showing the indications, potential pitfalls and perioperative complications. METHODS: Between September 2016 and March 2017, 18 patients with indication for primary and secondary prevention of sudden cardiac death, with no concomitant indication for artificial cardiac pacing, were included. RESULTS: The implantation of the subcutaneous implantable cardioverter defibrillator successfully performed in 18 patients. It was difficult to place the subcutaneous lead at the parasternal line in two patients. One patient returned a week after the procedure complaining about an increase in pain intensity at pulse generator pocket site, which was associated with edema, temperature rising and hyperemia. Two patients took antialgic medication for five days after surgery. A reintervention was necessary in one patient to replace the lead in order to correct inappropriate shocks caused by myopotential oversensing. CONCLUSION: In our initial experience, although the subcutaneous implantable cardioverter defibrillator implantation is a less-invasive, simple-accomplishment procedure, it resulted in a bloodier surgery perhaps requiring an operative care different from the conventional. Inappropriate shock by oversensing is a reality in this system, which should be overcame in order not to become a limiting issue for its indication.

Cytotoxic and genotoxic effects induced by stannous chloride associated to nuclear medicine kits.

At present, more than 75% of routine nuclear medicine diagnostic procedures use technetium-99m (99mTc). The binding between 99mTc and the drug to obtain the radiopharmaceutical needs a reducing agent, with stannous chloride (SnCl2) being one of the most used. There are controversies about the cytotoxic, genotoxic and mutagenic effects of SnCl2 in the literature. Thus, the approaches below were used to better understand the biological effects of this salt and its association in nuclear medicine kits [methylenediphosphonate (MDP) bone scintigraphy and diethylenetriaminepentaacetic acid (DTPA) kidney and brain scintigraphy]: (i) bacterial inactivation experiments; (ii) agarose gel electrophoresis of supercoiled and linear plasmid DNA and (iii) bacterial transformation assay. The Escherichia coli strains used here were AB1157 (wild type) and BW9091 (xthA mutant). Data obtained showed that both MDP and SnCl2 presented a high toxicity, but this was not observed when they were assayed together in the kit, thereby displaying a mutual protect effect. DTPA salt showed a moderate toxicity, and once more, the DTPA kit provided protection, compared to the SnCl2 effect alone. The results suggest a possible complex formation, either MDP-SnCl2 or DTPA-SnCl2, originating an atoxic compound. On the other hand, SnCl2-induced cell inactivation and the decrease in bacterial transformation generated by DTPA found in XthA mutant strain suggest that the lack of this enzyme could be responsible for the effects observed, being necessary to induce DNA damage repair.

Integrated continuous care: collaborating with the elderly functionality / Cuidado contínuo integrado: colaborando para a funcionalidade do idoso

This study aimed to evaluate the influence of Integrated Continuous Care on the functional independence of the elderly. This cohort study included participants aged 60 years or older who had experienced a disabling event or disease, and were admitted to rehabilitation in a Brazilian Integrated Continuous Care Unit. The functional gain was evaluated by the Barthel index.Fifty-nine elderly individuals admitted due to a disabling event or disease at the ICCU were assisted from March 2014 to February 2015. Since twenty-two of these were excluded, only 37 participants were evaluated. The mean age of the elderly that were included was 70.41 years (± 1.40) and most of them presented an ischemic stroke diagnosis (64.9%). The total functional gain was 24.05 (± 3.84) points, with an average stay of 32.32 (± 2.18) days. When compared with the degree of dependence on the admission and at discharge, total or severe dependence was identified in 62.2% on admission and mild dependence or total independence was identified in 54.1% at discharge, with a significant decrease in the percentage of the elderly with total dependence between admission and discharge (McNemar test, p = 0.001). At hospital discharge, 70.3% of the elderly had better individual performance in their Activities of Daily Living than at hospital admission and none of them got worse. The multi-professional team-based approach in the Integrated Continuous Care assistance model favors the elderly with gain in functionality and independence. The social network involvement of the elderly lead to their empowerment and co-responsibility along with their family/caregiver in pursuit of the therapeutic goals established together.

Investigar a influência dos Cuidados Continuados Integrados na independência funcional de idosos. Este estudo de coorte incluiu participantes com 60 anos ou mais que sofreram algum evento ou doença incapacitante e que foram internados para reabilitação em Unidade Brasileira de Cuidados Continuados Integrados. O ganho funcional foi avaliado pelo índice de Barthel. Cinquenta e nove idosos admitidos por um evento ou doença incapacitante na UCCI foram atendidos de março de 2014 a fevereiro de 2015. Como vinte e dois deles foram excluídos, apenas 37 participantes foram avaliados. A média de idade dos pacientes incluídos foi de 70,41 anos (± 1,40) e a maioria apresentou AVC isquêmico como diagnóstico (64,9%). O ganho funcional total foi de 24,05 (± 3,84) pontos, com tempo médio de permanência de 32,32 (± 2,18) dias. Quando comparados o grau de dependência na admissão e na alta, a dependência total ou grave foi identificada em 62,2% na admissão e a dependência leve ou independência total foi identificada em 54,1% na alta, com uma diminuição significativa no percentual de pacientes com dependência total entre admissão e alta (teste de McNemar, p = 0,001). Na alta hospitalar, 70,3% dos pacientes apresentaram melhor desempenho individual em suas Atividades de Vida Diária do que no momento da admissão hospitalar e nenhum paciente piorou. A abordagem multiprofissional baseada em equipe no modelo assistencial do Cuidado Integrado Contínuo beneficia o idoso, com ganho de funcionalidade e independência. O envolvimento do paciente na rede social leva ao empoderamento e corresponsabilidade deste e da família/cuidador na busca dos objetivos terapêuticos estabelecidos em conjunto.

OBJECTIVE: To understand the evolution of AIDS over time in Mato Grosso do Sul, Brazil, using incidence, lethality, and mortality coefficients. METHODS: A descriptive epidemiological study based on time series analysis of secondary data from the Notifiable Diseases Information System reported between 1985 and 2012. RESULTS: The prevalence of AIDS was higher among men, with evidence of feminization during the first 14 years of the epidemic. There was no statistically significant sex difference in AIDS lethality. Women were 1.3 times more likely to survive than men. CONCLUSIONS: Gender differences must be considered when designing new HIV/AIDS prevention strategies.

Integrated continuous care: implementation in Mato Grosso do Sul, Brazil / Cuidado contínuo integrado: implantação em Mato Grosso do Sul, Brasil

The demographic transition that occurred in Brazil brought changes in its health indicators. Integrated Continuous Care (ICC) was organized as a health care model aimed at increasing the independence and well-being of people with acute or recent functional dependence. This study aimed to describe the development and implementation of the Integrated Continuous Care in the state of Mato Grosso do Sul, Brazil. This care model utilized the principles of the National Humanization Policy, such as the extended and shared clinic, embracement, educational practices and meetings with caregivers, families, and patients, open visits, participation and autonomy of the patient and family in the construction of the Singular Therapeutic Project, and shared discharge from hospital. Assistance and support to patients who were already released from ICC must be increased in the primary health care setting to ensure continuity of recovery, better readaptation, and successful family and social reintegration. As a positive result, we set up an outpatient clinic for ICC patients who needed continuous clinical follow-up after rehabilitation. This allows patient re-evaluation, reduces re-admission rates, and maintains the domiciliary care management educational process. As an innovative approach to improving health care outcomes, ICC allows the patients to leave the hospital environment and go home on some weekends. The ICC project has enabled many advances, especially in patient-centered care and shared decision-making. The support of the São Julião Hospital administration has been vital to the success of ICC Unit treatments.

A transição demográfica identificada no Brasil trouxe mudança de indicadores de saúde. Os Cuidados Continuados Integrados (CCI) se formatam como um modelo de assistência que busca aumentar a independência e bem estar das pessoas com dependência funcional aguda ou recente. O estudo tem como objetivo de descrever a construção e implantação dos Cuidados Continuados Integrados no estado de MatoGrosso do Sul, Brasil. Este modelo de assistência utiliza ferramentas da Política Nacional de Humanização, como clínica ampliada e compartilhada, acolhimento, práticas educativas e reuniões com cuidadores, familiares e pacientes, visitas abertas, participação e autonomia do paciente e familiares no projeto terapêutico singular e alta compartilhada. A assistência e o apoio aos pacientes pós-alta CCI precisam ser fortalecidos na rede básica de saúde, a fim de garantir a continuidade da recuperação, readaptação e perfeita reinserção familiar e social. Como resultado positivo, iniciou-se o ambulatório para pacientes egressos do CCI que precisavam de acompanhamento clínico contínuo após a reabilitação. Esse ambulatório permite a reavaliação do paciente, contribui para reduzir a reinternação e mantém o processo educacional de gerenciamento do cuidado domiciliar. Enquanto inovação em saúde para melhorar os resultados dos cuidados de saúde, o CCI permite a saída dos pacientes do ambiente hospitalar para o domicilio em alguns finais de semana. O projeto CCI trouxe muitos avanços, especialmente o cuidado centrado no paciente e a decisão compartilhada. O apoio da administração do Hospital São Julião tem sido vital para o sucesso dos tratamentos realizados na unidade CCI.

Pertussis in the central-west region of Brazil: one decade study.

In many parts of the world, numerous outbreaks of pertussis have been described despite high vaccination coverage. In this article we report the epidemiological characteristics of pertussis in Brazil using a Surveillance Worksheet. Secondary data of pertussis case investigations reported from January 1999 to December 2008 recorded in the Information System for Notifiable Diseases (SINAN) and the Central Laboratory for Public Health (LACEN-MS) were utilized. The total of 561 suspected cases were reported and 238 (42.4%) of these were confirmed, mainly in children under six months (61.8%) and with incomplete immunization (56.3%). Two outbreaks were detected. Mortality rate ranged from 2.56% to 11.11%. The occurrence of outbreaks and the poor performance of cultures for confirming diagnosis are problems which need to be addressed. High vaccination coverage is certainly a good strategy to reduce the number of cases and to reduce the impact of the disease in children younger than six months.

As complicações relacionadas ao cardioversor-desfibrilador implantável em geral estão relacionadas a implante de cabo-eletrodo transvenoso, fratura do condutor ou ruptura do isolamento de silicone, além de infecções. Essas complicações podem ser evitadas com o implante do sistema de cardioversor-desfibrilador implantável totalmente subcutâneo. Relatamos o caso de um paciente de 60 anos de idade, assintomático, com antecedentes de morte súbita cardíaca na família, submetido ao primeiro implante de cardioversor-desfibrilador implantável subcutâneo no Brasil

Complications related to the use of implantable cardioverter-defibrillator are often related to transvenous lead implant, conductor fracture or insulation disruption in addition to infections. These complications may be avoided by implanting a totally subcutaneous implantable cardioverter-defibrillator system. We report the case of a 60-year old, asymptomatic patient with a family history of cardiac sudden death, undergoing the first subcutaneous implantable cardioverter-defibrillator implant in Brazil

Characterization of drug prescriptions in an adult intensive care unit. / Caracterização das prescrições medicamentosas em unidade de terapia intensiva adulto.

OBJECTIVE: To characterize drug prescriptions in a university hospital adult intensive care unit. METHODS: Single-center, observational, descriptive, cross-sectional study conducted at an adult general intensive care unit. The study population included all of the unit's inpatients from January to March 2011. The following characteristics for all prescriptions recorded during this period were examined: drug name (generic, brand name or abbreviation), dosage strength, pharmaceutical form, dose, route of administration, patient name, patient registration in the institution, clinic and hospital bed as well as the name, board license number, signature of the prescriber and date of the prescription. It was quantified the percentage of prescribed drugs included in the National List of Essential Drugs, the World Health Organization Model List of Essential Medicines and the University Hospital Center Pharmacotherapy Guide. The prescribed drugs were classified based on the Anatomical Therapeutic Chemical classification system (levels 1 and 2). RESULTS: Eight hundred forty-four prescriptions were reviewed from 72 patients (mean age: 59.04 ± 21.80), 54.92% of whom were female. The mean number of prescriptions per patient was 11.72 ± 11.68. The total number of drugs prescribed was 12,052 and 9,571 (79.41%) of the drugs were prescribed using the generic name. The most frequent absent information in the drug description was the pharmaceutical form of the drug (8,829/73.26%). The dosage strength was indicated in 7,231 (60%) of the prescriptions, and the prescriber and patient information were indicated in over 96% of the prescriptions. The prescribed drugs were classified in 13 therapeutic groups and 55 subgroups. Systemic antibacterials represented one of the most frequently prescribed subgroups. CONCLUSION: Most of the reviewed information was present in the prescriptions. However, the dosage strength and pharmaceutical form were absent in many prescriptions. The characterization of prescriptions at different hospital units is essential for the development of strategies that reduce drug utilization problems.
