Avaliação clínica e endoscópica em pacientes com sintomas gastroesofágicos / Clinical and endoscopic evaluation in patients with gastroesophageal symptoms

ABSTRACT BACKGROUND: The gastroesophageal reflux disease (GERD) is the most common esophageal disease in medical practice, and it is suspected according to patients' symptoms. GERD can be classified in erosive esophagitis (EE) according to the presence of upper gastrointestinal endoscopy findings. OBJECTIVE: To evaluate endoscopic findings in patients with symptoms suggestive of GERD comparing epicemiological and risk factors. METHODS: Upper endoscopy reports were examined retrospectively from patients with symptoms of GERD such as heartburn, regurgitation, cough, throat clearing, globus and chest pain. EE was determined based on Los Angeles classification. Comparisons between risk factors in EE and non-EE groups were done with statistical analysis. RESULTS: A total of 984 endoscopic reports were examined and 676 selected for analysis (281 with EE and 395 with non-EE form). Most were female 381 (56.36%) with a mean age of 44.01±15.40 years. Hiatal hernia was present in 47(6.96%) and smoking in 41(6.07%). Univariate logistic regression showed that male (OR=2.24, CI 95%, 1.63-3.06) and hiatal hernia (OR=4.52, CI 95%, 2.30-8.89) were independent predictors of erosions in the EE group. The presence of hiatal hernia (OR=12.04, CI 95%, 3.57-40.62), smoking (OR=8.46, CI 95%, 3.28-31.32) and aged patients (OR=8.01, CI 95%, 2.42-26.49) were also indicated as a risk factor for severe EE (grades C and D of Los Angeles). CONCLUSION Male gender and hiatal hernia were associated with EE. Aged patients, smoking and hiatal hernia were related to severe EE. It is suggested that the risk factors for EE and non-EE types are different. Cohort studies are necessary to identify the exact mechanisms involved in each disease form.

RESUMO CONTEXTO: A doença do refluxo gastroesofágico (DRGE) é uma das doenças digestivas mais comuns na prática médica e deve ser suspeitada de acordo com os seus sintomas clínicos, podendo ser classificada em esofagite erosiva (EE) de acordo com os achados de endoscopia. OBJETIVO: Avaliar os achados endoscópicos em pacientes com sintomas sugestivos de DGRE comparando fatores de risco e epidemiológicos. MÉTODOS: Resultados de endoscopias digestiva foram examinados retrospectivamente de pacientes com sintomas relacionados com DRGE como pirose, regurgitação, tosse, pigarro, globus e dor torácica. EE foi determinada de acordo com a classificação de Los Angeles. Comparação de fatores de risco entre os grupos EE e não-EE foram feitos com análise estatística. RESULTADOS: Um total de 984 endoscopias foram examinadas e 676 endoscopias selecionadas para análise (281 com EE e 395 sem EE). A maioria dos pacientes era do sexo feminino 381 (56,36%) com uma idade média de 44,01±15,40 anos. Hérnia hiatal esteve presente em 47 (6,96%) e tabagismo em 41 (6,07%). Regressão logística uni variada mostrou que sexo masculino (OR=2,24 - IC 95%: 1,63-3,06) e hérnia hiatal (OR=4,52 - CI 95%: 2,30-8,89) foram fatores de risco independentes de EE. A presença de hérnia hiatal (OR=12,04 - CI 95%: 3,57-40,62), tabagismo (OR=8,46 - CI 95%: 3,28-31,32) e pacientes idosos (OR=8,01 - CI 95%, 2,42-26,49) foram fatores de risco no grupo de EE grave (classes C e D de Los Angeles). CONCLUSÃO: Sexo masculino e hérnia hiatal foram associados com EE. Idade avançada, tabagismo e hérnia hiatal foram relacionados à forma grave de EE. É sugerido que os fatores de risco de pacientes com e sem EE sejam diferentes. Estudos de coorte são necessários para identificar os mecanismos exatos envolvidos em cada forma da doença.

Segurança e eficácia do uso de cianoacrilato + coil guiado por ultrassom endoscópico versus técnica convencional de cianoacrilato no tratamento de varizes gástricas: um ensaio clínico randomizado / Safety and efficacy of eus-guided coil plus cyanoacrylate versus conventional cyanoacrylate technique in the treatment of gastric varices: a randomized controlled trial

ABSTRACT BACKGROUND: One of the most feared complications with the use of cyanoacrylate for treatment of gastric varices is the occurrence of potentially life-threatening systemic embolism. Thus, endoscopists are turning towards new techniques, including endoscopic coiling, as a potentially safer and more effective treatment option. However, no studies have been performed comparing the two techniques. OBJECTIVE: This study aims to compare the safety and efficacy of endoscopic ultrasound guided coil and cyanoacrylate injection versus the conventional technique of injection of cyanoacrylate alone. DESIGN: A pilot randomized controlled trial. METHODS: Patients randomized into group I were treated with coil and cyanoacrylate, and those in group II with cyanoacrylate alone. Flow within the varix was evaluated immediately after the treatment session and one month following initial treatment. If thrombosis was confirmed, additional follow-up was performed 4 and 10 months following initial treatment. All patients underwent a thoracic computerized tomography scan after the procedure. RESULTS: A total of 32 patients, 16 in each group, were followed for an average of 9.9 months (range 1-26 months). Immediately after the procedure, 6 (37.5%) group-I patients and 8 (50%) group-II patients presented total flow reduction in the treated vessel (P=0.476). After 30 days, 11 (73.3%) group-I patients and 12 (75%) group-II patients were found to have varix thrombosis. In both groups, the majority of patients required only one single session for varix obliteration (73.3% in group I versus 80% in group II). Asymptomatic pulmonary embolism occurred in 4 (25%) group-I patients and 8 (50%) group-II patients (P=0.144). No significant difference between the groups was observed. CONCLUSION: There is no statistical difference between endoscopic ultrasound guided coils plus cyanoacrylate versus conventional cyanoacrylate technique in relation to the incidence of embolism. However, a greater tendency towards embolism was observed in the group treated using the conventional technique. Both techniques have similar efficacy in the obliteration of varices. Given the small sample size of our pilot data, our results are insufficient to prove the clinical benefit of the combined technique, and do not yet justify its use, especially in light of higher cost. Further studies with larger sample size are warranted.

RESUMO CONTEXTO: Uma das complicações mais temidas com o uso de cianoacrilato para tratamento de varizes gástricas é a ocorrência de embolia sistêmica potencialmente fatal. Assim, os endoscopistas estão se aprimorando com novas técnicas, incluindo o uso de coils endoscópico, como uma opção de tratamento potencialmente mais segura e eficaz. No entanto, nenhum estudo foi realizado comparando as duas técnicas. OBJETIVO: Este estudo tem como objetivo comparar a segurança e eficácia da injeção de coil com cianoacrilato guiados por ultrassom endoscópico versus a técnica convencional de injeção de cianoacrilato. DESIGN: Um ensaio piloto controlado aleatoriamente. MÉTODOS: Os pacientes randomizados para o grupo I foram tratados com coil + cianoacrilato e os do grupo II apenas com cianoacrilato. O fluxo dentro da variz foi avaliado imediatamente após a sessão de tratamento e um mês após o tratamento inicial. Se a trombose foi confirmada, o acompanhamento adicional era realizado em 4 e 10 meses após o tratamento inicial. Todos os pacientes foram submetidos a uma tomografia computadorizada torácica após o procedimento. RESULTADOS: Um total de 32 pacientes, 16 em cada grupo, foram acompanhados por uma média de 9,9 meses (variação de 1-26 meses). Imediatamente após o procedimento, 6 (37,5%) pacientes do grupo I e 8 (50%) pacientes do grupo II apresentaram redução total do fluxo no vaso tratado (P=0,476). Após 30 dias, 11 (73,3%) pacientes do grupo I e 12 (75%) pacientes do grupo II apresentaram trombose da variz. Em ambos os grupos, a maioria dos pacientes necessitou de apenas uma única sessão para obliteração da variz (73,3% no grupo I versus 80% no grupo II). Embolia pulmonar assintomática ocorreu em 4 (25%) pacientes do grupo I e em 8 (50%) pacientes no grupo II (P=0,144). Nenhuma diferença significativa entre os grupos foi observada. CONCLUSÃO Apesar de não haver diferença estatística entre os dois grupos em relação à incidência de embolia neste estudo piloto, observou-se maior tendência de embolia no grupo tratado pela técnica convencional.

Low dose systemic or intralesional meglumine antimoniate treatment for American tegumentary leishmaniasis results in low lethality, low incidence of relapse, and low late mucosal involvement in a referral centre in Rio de Janeiro, Brazil (2001-2013)

BACKGROUND American tegumentary leishmaniasis (ATL) is a non-lethal parasitic disease that presents with cutaneous (CL) and mucosal (ML) clinical forms. ATL treatment aims at healing the lesions and preventing the development of the late mucosal form. Systemic meglumine antimoniate (MA) therapy with 10-20 mg Sb5+/kg/day is the first choice of treatment. However, alternative therapies using 5 mg Sb5+/kg/day or intralesional (IL) MA are the usual regimens at the National Institute of Infectious Diseases (NIID), Rio de Janeiro, Brazil. OBJECTIVES To evaluate lethality and the incidence of relapse and development of late ML in CL patients treated at NIID from 2001 until 2013. METHODS Data were recovered from records of all ATL patients diagnosed during that period. FINDINGS Out of 777 patients, 753 were treated with MA (96.9%). Of those, 89.1% received alternative therapy of 9.9% IL and 79.2% systemic 5 mg Sb5+/kg/day. Some patients required 1-3 additional courses of treatment, thus making a total of 997 courses; 85.2% of them were subjected to alternative therapies. Lethality was 0.1%, relapse incidence 5.8%, and late ML incidence 0.25%. As a final outcome for the 777 patients, 95.9% were cured, 0.1% died and 4.0% were not able to follow-up. MAIN CONCLUSIONS Alternative MA schedules resulted in low lethality without increase of relapse or late ML incidence.

Pre-tibial myxedema: treatment with intralesional corticosteroid

The pretibial myxedema is a manifestation of Graves' disease characterized by accumulation of glycosaminoglycans in the reticular dermis. The dermopathy is self-limiting but in some cases may cause cosmetic and functional damage. Conventional treatment is use of topical steroids under occlusive dressing, however the intralesional application has shown good results. We present a case of pretibial myxedema treated with single injection of intralesional corticosteroid.

Evaluation of percutaneous ethanol injections in benign thyroid nodules / Avaliação do tratamento com injeção percutânea com etanol em nódulos benignos de tireoide

Objective The objective of this study was to evaluate the efficacy and safety of percutaneous ethanol injection (PEI) in the treatment of benign thyroid nodules. Subjects and methods We evaluated 120 patients with benign thyroid nodules. Patients underwent evaluation of serum TSH and free T4, cervical ultrasound, and thyroid scintigraphy (in those with suppressed TSH levels). The application of sterile ethanol 99% was guided by ultrasound, with the injected volume amounting to one-third of the nodule volume. Response was considered complete (reduction of 90%); partial (reduction between 50 and 90%); or none (reduction of < 50%). Autonomous nodules were evaluated for normalization of TSH levels. Results Among the nodules studied, 30.8% were solid, 56.7% were mixed, 12.5% were cystic, and 21.6% were hyperfunctioning. The initial volume of the treated nodules ranged from 0.9 to 74.8 mL (mean 13.1 ± 12.4 mL). We performed 1-8 sessions of PEI, applying an average of 6.2 mL of ethanol for patient. After 2 years of follow-up, 17% of patients achieved a complete response (94% reduction); 53%, a partial response (70% reduction); and 30%, no response. A reduction in the volume of autonomous nodules was noted in 70% of cases, and 54% had a normalized value of TSH. The main side effect is local pain, lasting less than 24 hours in most cases. Conclusion This study showed that PEI is a safe and effective procedure for treatment of benign, solid or mixed thyroid nodules. Most cases resulted in significant reduction in nodule volume, with normalization of thyroid function. Arq Bras Endocrinol Metab. 2014;58(9):912-7 .

Objetivo O objetivo deste estudo foi avaliar a eficácia e segurança da injeção percutânea de etanol (IPE) no tratamento de nódulos tireoidianos benignos. Sujeitos e métodos Foram avaliados 120 pacientes com nódulos benignos de tireoide. Todos realizaram dosagens de TSH, T4 livre, ecografia cervical (US) e cintilografia de tireoide (em pacientes com TSH suprimido). A aplicação de etanol estéril a 99% foi guiada por US e o volume de etanol injetado correspondeu a um terço do volume nodular calculado. A resposta foi considerada completa (redução de 90%); parcial (redução entre 50 e 90%) ou ausência de resposta (redução menor que 50%). Nos nódulos autônomos, foi avaliada a normalização do TSH. Resultados Entre os nódulos estudados, 30,8% eram sólidos, 56,7% eram mistos, 12,5% eram císticos e 21,6%, nódulos hiperfuncionantes. O volume inicial dos nódulos tratados variou de 0,9 a 74,8 mL (média 13,1 ± 12,4 mL). Foram realizadas de 1 a 8 sessões de IPE (média 2,8), com aplicação média de 6,2 mL de etanol por paciente. Após dois anos de seguimento, 17% dos pacientes obtiveram resposta completa (redução de 94%), 53% obtiveram resposta parcial (redução de 70%) e 30% não responderam. Houve redução de volume nos nódulos autônomos em 70% dos casos, e 54% normalizaram o valor do TSH. Os efeitos colaterais registrados foram decorrentes apenas do desconforto no local de aplicação. Conclusão Este trabalho mostrou que a IPE é um procedimento seguro e eficaz para tratamento de nódulos benignos, sólidos ou mistos de tireoide. ...

Intralesional immunotherapy with killed Mycobacterium indicus pranii vaccine for the treatment of extensive cutaneous warts.

Background: Multiple cutaneous warts in adults are often symptomatic, cosmetically disabling, and difficult to treat. Killed Mycobacterium indicus pranii (previously known as Mycobacterium w, popularly known as Mw) vaccine has earlier been investigated in genital warts with encouraging results. Objective: To evaluate the efficacy and safety profile of intralesional injected killed Mw vaccine for the treatment of extensive extragenital cutaneous warts. Methods: In this study, a retrospective analysis of medical records was performed in patients with cutaneous warts treated with intralesional Mw vaccine. Only patients with more than 5 extra‑genital warts, involving at least two body sites and which had not shown any signs of spontaneous regression over 6 months were treated with the vaccine. Results: Forty four patients were treated with intralesional Mw vaccine. The mean number of warts was 41.5 ± 25.7 with a disease duration of 3.1 ± 2.5 years. Complete clearance was achieved in 24 (54.5%) patients with a mean of 3.4 ± 1.1 intralesional injections. Cosmetically acceptable response to therapy (>75% clearance) was achieved in 37 (84.1%) patients. Wart response at distant sites was seen in 38 (86.3%) patients. Thirty‑six patients (81.8%) experienced mild therapy‑related side effects. Eighteen patients with complete response were followed up for 5.27 ± 1.7 months and none had recurrence of lesions. Conclusions: Killed Mw vaccine is safe and effective in the treatment of extensive cutaneous warts. Larger, preferably randomized controlled trials are needed to assess its efficacy vis a vis standard therapies for warts.

Cystic craniopharyngioma: intratumoral chemotherapy with alpha interferon / Craniofaringioma cístico: quimioterapia intratumoral com interferon alfa

OBJECTIVE: To assess whether the cystic craniopharyngiomas can be controlled with the use of intratumoral applications of interferon alpha. METHOD: Nineteen patients with the diagnosis of cystic craniopharyngioma were treated with intratumoral chemotherapy with interferon alpha from January 2002 to April 2006. All patients underwent placement of an intracystic catheter connected to an Ommaya reservoir. Through this reservoir were made applications during chemotherapy cycles. Each cycle corresponded to application of 3,000,000 units of interferon alpha three times per week on alternate days totalizing 36,000,000 units. Response to treatment was evaluated by calculating the tumor volume on MRI control after one, three and six months after the end of each cycle. Patients who developed worsening of symptoms or who had insignificant reduction in tumor volume during follow-up underwent repeat cycle chemotherapy. RESULTS: Four patients received four cycles of chemotherapy, three patients received three cycles, six patients received two cycles and six patients received one. The lower percentage of reduction in tumor volume was 60 percent and the bigger reduction was 98.37 percent. Eleven patients had a reduction greater than 90 percent. Five patients had a tumor reduction between 75 and 90 percent and in three patients the tumors were reduced by less than 75 percent. No deaths occurred during treatment and side effects of interferon alpha were well tolerated. No treatment was discontinued. Follow-up after the last application ranged from one year and five months to three years and nine months. CONCLUSION: The intratumoral chemotherapy with interferon alpha decreases the volume of cystic craniopharyngiomas and so far can be considered a new therapeutic alternative.

OBJETIVO: Avaliar se os craniofaringiomas císticos podem ser controlados com aplicações intratumorais de interferon alfa. MÉTODO: De janeiro de 2002 a abril de 2006, 19 pacientes foram submetidos à colocação de um cateter intracístico conectado a reservatório de Ommaya para aplicações intratumorais de ciclos de 36.000.000 de unidades de interferon alfa. A resposta ao tratamento foi avaliada pelo cálculo do volume tumoral na ressonância magnética de controle ao término de cada ciclo. RESULTADOS: Os pacientes receberam de um a quatro ciclos de quimioterapia. Onze pacientes apresentaram uma redução do volume tumoral maior que 90 por cento; cinco pacientes apresentaram uma redução entre 75 por cento e 90 por cento e três pacientes uma redução menor de 75 por cento. Não houve óbitos durante o tratamento e os efeitos colaterais do inferferon alfa foram bem tolerados. Nenhum tratamento foi interrompido. CONCLUSÃO: A quimioterapia intratumoral com interferon alfa diminui o volume dos craniofaringeomas císticos e pode ser considerada uma nova alternativa terapêutica.

Promising early results for keloid treatment with intralesional colchicine: a clinical and histopathological study

To evaluate the effect ofcolchicine local infiltration in the treatment of keloids. Prospective study. National Hepatology and Tropical Medicine Research Institute [NHTMRI]. In a clinical trial, 14 cases with keloids were treated by local infiltration ofcolchicine. The results were evaluated objectively and subjectively. Lesional biopsy was obtained before and after treatment and examined by light microscopy. Marked reduction of the size of the lesions and decrease of such complaints as itching and erythema were noted. Favorable results were obtained according to the patients in 83.4% and according to the opinion of the medical examiner in 91.7% of cases. Systemic complications of colchicine absorption, i.e. nausea, did not occur in any patient. Histopathological examination of the lesions after colchicine infiltration reveled marked reduction in the density of collagen bundles, which are widely dispersed through out the dermis. intralesional infiltration of colchicine is safe and effective treatment, of keloids

Intralesional theory of cutaneous leishmaniasis with hypertonic sodium chloride solution

One hundred and fifty-two liesions of cutaneous leishinaniasis in 70 patients were treated with intralesional hypertonic sodium chloride [116 lesions], intralesional pentostam [26 lesions], and 10 lesions were left untreated as controls. The injections were given at 10 day intervals and patients were followed-up for 42 days. intralesional hypertonic sodium chloride solution was shown to be very effective local therapy [88.2% cure rate], and was as effective as intralesional pentostam [88.9% cure rate]. In both types of therapy most lesions needed either one or two injections, and rarely more injections were needed. Mild improvement was noticed after 10 days of the first injection, while the cure was noticed within 2-6 weeks

Comparative study on local injection therapy of chalazia

Ninety five chalazia were treated with local injections. Small cystic chalazia responded best to intralesional steroid. Acute infected lesions did better if an antibiotic was added to the steriod Injection. Hard, long-standing chalazia did not respond well either to intra. or paralesional steriod injection with or without an antibiotic. The control group injected with saline and followed for a similar period did not show any spontaneous resolution
