The role of maxillary sinus puncture on the diagnosis and treatment of patients with hospital-acquired rhinosinusitis.

UNLABELLED: Rhinosinusitis is one of the most common causes of fever of unknown origin in critically ill patients and should be systematically searched. OBJECTIVE: This study aims to evaluate the diagnostic and therapeutic effect of maxillary sinus puncture performed at the bedside in patients with infective rhinosinusitis hospitalized in an Intensive Care Unit of a high complexity care hospital. MATERIALS AND METHODS: This retrospective study looks into patients on mechanical ventilation with fever of unknown origin and signs of rhinosinusitis on CT images who were submitted to inferior meatus maxillary sinus puncture. RESULTS: The total study sample consisted of 27 patients (70.3% male; mean age 45.3 years). The most common Intensive Care Unit admission diagnoses were head trauma and stroke. CT scans revealed the maxillary (85.2%) and sphenoid (74.1%) sinuses were the most involved paranasal sinuses. Middle meatus purulent drainage was seen in 30.7% of the nasal cavities. Fever was reduced in 70.4% of the patients after puncture (p < 0.001). The most commonly found organisms in sinus aspirates were Pseudomonas aeruginosa and Acinetobacter baumannii. CONCLUSION: Maxillary sinus puncture performed at the bedside of the patients is an important diagnostic and therapeutic tool for critically ill patients.

Papel da punção do seio maxilar no diagnóstico e no tratamento de pacientes com rinossinusite hospitalar / The role of maxillary sinus puncture on the diagnosis and treatment of patients with hospital-acquired rhinosinusitis

A rinossinusite é uma das principais causas de febre em pacientes críticos e deve ser sistematicamente pesquisada. OBJETIVO: Avaliar o impacto da punção do seio maxilar à beira leito, no diagnóstico e no tratamento dos pacientes com rinossinusite infecciosa internados em Unidade de Terapia Intensiva de um hospital universitário de alta complexidade. MATERIAIS E MÉTODOS: Estudo retrospectivo que avaliou os pacientes em ventilação mecânica com febre de origem indeterminada e sinais tomográficos de rinossinusite submetidos à punção do seio maxilar pelo meato inferior. RESULTADOS: A amostra total do estudo consistiu de 27 pacientes (70,3% do sexo masculino com média de idade 45,3 anos). Os diagnósticos de admissão mais frequentes na Unidade de Terapia Intensiva foram Trauma Crânio Encefálico e Acidente Vascular Cerebral. No exame tomográfico, os seios paranasais mais acometidos foram o maxilar, em 85,2%, e esfenoidal, em 74,1%. A secreção purulenta foi visualizada no meato médio em 30,7% das fossas nasais. Os microrganismos mais frequentes nos aspirados dos seios foram Pseudomonas aeruginosa e Acinetobacter baumannii. CONCLUSÃO: A punção do seio maxilar à beira leito demonstrou-se uma importante ferramenta diagnóstica e terapêutica nos pacientes de UTI com rinossinusite hospitalar, submetidos à ventilação mecânica invasiva.

Acupuncture for tinnitus immediate relief.

The treatment of tinnitus, which is defined as conscientious perception of a sound originated in the ears or nervous system, represents until the current days a great challenge. The use of Acupuncture (ACP) is based on the stimulation with needles of specific points on the human anatomy. A prospective, randomized and double-blinded study was carried through in 76 patients taken care of in the Clinic of Tinnitus of the Department of Otorhinolaryngology and Head and Neck Surgery of the UNIFESP-EPM in the period understood between April and June of 2005. All the patients had humming complaint and had been submitted to clinical anamnese, physical examination and subsidiary exams in order to investigate its etiology. The patients then were directed to a first researcher that determined an initial numeric value of the humming through Visual Analoge Scale(VAS), varying from 0 to 10 points. After this, had been directed for another room in which an acupuncturist doctor, who did not have access to the initial evaluation, separated the patients in Group Control and Group Study according to the attendance order, in alternating way. The ACP point used in patients of the Group Study places 6,5 cm above of the apex of the auditory pavilion in the parietal region. The point used in the Group Control places 3 cm above of the previous point, in the same vertical line. Then they had been sent back to the initial room for a new evaluation by the first researcher, where they had been guided to redefine the subjective score of the humming. Among the 76 studied patients, 29 were male (38,2%) and 47 female (61,8%), with average age 56,9 + 12,0 years. The Groups Study and Control had counted on 38 patients each. Through the Anova test it was evidenced that it had significant difference (p<0,001) between the moments pre and post needling and that in the group Study this improvement is more evident (p=0,0127). The t-independent test showed that it had a significant difference (p=0,017) between the two moments in the groups Study and Control. We conclude that there was significant reduction of the counting of the moments pre and post needling in both the groups, and in the group study the reduction is greater that in the group control.

O uso da acupuntura para alívio imediato do zumbido / Acupuncture for tinnitus immediate relief

O zumbido, definido como percepção consciente de um som originado nas orelhas ou no sistema nervoso do paciente, representa até os dias atuais um grande desafio no que concerne seu tratamento, baseia-se na estimulação com agulhas de pontos específicos definidos sobre a anatomia humana. A utilização da Acupuntura (ACP) em sintomas como o zumbido assemelha-se ao modelo aplicado nos quadros álgicos, já que ambos estão relacionados como experiência sensorial e emocional subjetiva e desagradável. OBJETIVO: Estudar a eficácia da acupuntura no alívio sintomático de forma aguda no zumbido. FORMA DE ESTUDO: Clínico prospectivo. MATERIAL E MÉTODO: Foi realizado um estudo prospectivo, randomizado e duplo-cego em 76 pacientes atendidos no Ambulatório de Zumbido do Departamento de Otorrinolaringologia e Cirurgia de Cabeça e Pescoço da UNIFESP-EPM no período compreendido entre abril e junho de 2005. Todos os pacientes tinham queixa de zumbido e foram submetidos a anamnese clínica, exame físico e exames subsidiários a fim de se investigar sua etiologia. Os pacientes eram então encaminhados a um primeiro pesquisador que determinou um valor numérico subjetivo inicial do zumbido através de Escala Visual Analógica (EVA), variando de 0 a 10 pontos. Após isto, foram encaminhados para outra sala na qual um médico acupunturista, que não tinha acesso à avaliação inicial, separou os pacientes em Grupo Controle e Grupo Estudo de acordo com a ordem de atendimento, de maneira alternada. O ponto de ACP utilizado nos pacientes do Grupo Estudo situa-se a 6,5cm acima do ápice do pavilhão auditivo na região têmporo-parietal. O ponto utilizado no Grupo Controle situa-se 3cm acima do ponto anterior, na mesma linha vertical. Foram então encaminhados à sala inicial para uma nova avaliação pelo primeiro pesquisador, onde foram orientados a redefinir o escore subjetivo do zumbido. RESULTADOS: Dos 76 pacientes estudados, 29 eram do sexo masculino (38,2 por cento) e 47 do sexo feminino (61,8 por cento), com idade média 56,9 + 12,0 anos. Os Grupos Estudo e Controle contaram com 38 pacientes cada. Através do teste Anova foi constatado que houve diferença significante (p<0,001) entre os momentos pré e pós-agulhamento e que no grupo Estudo essa melhora é bem maior (p = 0,0127)...
