Main etiological agents identified in 170 men with urethritis attended at the Fundação Alfredo da Matta, Manaus, Amazonas, Brazil,

Abstract Background: Sexually transmitted infections (STI) are a global public health problem. Urethritis are among the most common STIs, and can cause several complications and facilitate the transmission of the HIV virus. Objectives: To investigate the main etiologic agents of urethritis in 170 men treated at Fundação Alfredo da Matta. Methods: To identify the agents, urethral exudate and urine were collected. Gram and culture tests were performed in Thayer-Martin medium for Neisseria gonorrhoeae and polymerase chain reaction for Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis, Ureaplasma urealyticum, Ureaplasma parvum, Mycoplasma hominis, Mycoplasma genitalium, and herpes simplex types 1 and 2. Results: N. gonorrhoeae were identified in 102 (60.0%) patients, C. trachomatis in 50 (29.4%), U. urealyticum in 29 (17.0%), M. genitalium in 11 (6.5 %), U. parvum in ten (5.9%), and M. hominis in seven (4.1%). Herpes simplex type 2 was diagnosed in 24 (21.6%) of the 111 patients who underwent PCR for this pathogen. In 69 cases there was co-infection; the most frequent were: N. gonorrhoeae and C. trachomatis in 21 (14.7%) patients; N. gonorrhoeae and C. trachomatis in 21 (12.4%) patients; N. gonorrhoeae and herpes simplex type 2 in 11 (6.5%), and N. gonorrhoeae and U. urealyticum in nine (5.3%). Study limitations: Not relevant. Conclusion: N. gonorrhoeae, C. trachomatis, U. urealyticum, and herpes simplex type 2 were the pathogens most frequently identified in the present study. The main coinfection found was N. gonorrhoeae and C. trachomatis. T. vaginalis and herpes simplex type 1 were not identified in any of the patients.

Atypical manifestations of recent syphilis: study of 19 cases

Abstract Background: Syphilis is one of the most common diseases that start with genital ulcers. Aside from the initial, classic ulcerative lesion of syphilis, called hard chancre, atypical presentations are common, with erosions, erythema, edema, balanitis, and other dermatological manifestations. Associated with initial genital lesions, the presence of inguinal adenopathies is frequent, and the presence of hardened and painless lymphangitis on the dorsum of the penis is rare. Objectives: To describe atypical penile manifestations in patients with early syphilis. Methods: The present study reports patients who developed cord-like lesions on the penis. Results: The study included 25 patients with cord-like lesions on the penis; in 19 of those, the diagnosis of syphilis was confirmed. Study limitations: Small number of patients included. Conclusions: In view of the findings of the present investigation, it is important to emphasize that all patients who present with cord-like lesions on the penis must undergo a rapid test for syphilis, VDRL, serologies for HIV viral hepatitis B and C and, whenever possible, histopathological and Doppler exams.

[Healing process in cutaneous surgical wounds in rats under the influence of Orbignya phalerata aqueous extract]. / Análise comparativa da cicatrização da pele com o uso intraperitoneal de extrato aquoso de Orbignya phalerata (babaçu). Estudo controlado em ratos.

INTRODUCTION: The wounds healing is a highly complex process with many phases. Countless substances have been used since the remote times with the purpose a simulating the process. Among them the Orbignya phalerata extract was considered as having a stimulating action. PURPOSE: The aim of this study is to verify the healing action of the Orbignya phalerata in the healing of skin surgical wounds by a comparative analysis of the alterations obtained in histological and morphologic aspects. METHODS: Sixty male adult Wistar rats were used. They were distributed in a randomly in two groups of 30 each and, in one group, Orbignya phalerata extract was used intraperitoneally in a dose of 50 mg/Kg in the first day of surgery. The experimental procedure consisted in a circular incision of two centimeters of diameter with metallic punch. In the control group the substance was not used. The rats were killed in the 7th, 14th, 21st days of the post-operative period and submitted to macro and microscopic analysis. The macroscopic one was made with magnifying glass and paquimeter. For the histological analysis, the sheets were processed with Hematoxilina-Eosina (HE) and trichromic of Masson and slides the vascular proliferation, mononuclear cells, polymorphonuclear cells, fibroblastic proliferation, collagen fibers and re-epithelization were assigned. RESULTS: In the macroscopic view the experimental group of seven days had only one animal with small amount of secretion. In the animals of 14 days all of them had good aspect. The ones of 21 days, complete healing was observed in all animals. In the histological analysis, there was no significant difference among groups, except for the 7th day with significant difference in the fibroblastic proliferation and re-epithelization favoring the experimental group. CONCLUSION: A favorable effect of the aqueous extract of babassu mesocarp was observed in a microscope analysis in the healing process of cutaneous surgical wounds in rats.

Análise comparativa da cicatrização da pele com o uso intraperitoneal de extrato aquoso de Orbignya phalerata (babaçu): estudo controlado em ratos / Healing process in cutaneous surgical wounds in rats under the influence of Orbignya phalerata aqueous extract

INTRODUÇÃO: A cicatrização das feridas é processo altamente complexo com várias fases. Inúmeras substâncias têm sido usadas desde os tempos remotos para estimulá–la. Entre elas, o extrato da Orbignya phalerata com possível ação estimulante da cicatrização. OBJETIVO: verificar a ação cicatrizante da Orbignya phalerata na cicatrização das feridas cirúrgicas da pele através de análise comparativa das alterações histológicas e morfológicas. MÉTODOS: Foram utilizados 60 ratos, da linhagem Wistar, adultos e machos. Para o experimento, eles foram distribuídos de forma aleatória em dois grupos de 30 cada e usada a substância Orbignya phalerata intraperitoneal na dose de 50 mg/Kg, no primeiro dia da operação em um dos grupos. O procedimento experimental constituiu–se em incisão cutânea circular de dois centímetros de diâmetro com punch metálico. No grupo controle não foi usada a substância. Os ratos foram mortos nos 7°, 14°, 21° dias do pós–operatório. Realizou–se a análise macroscópica com lupa e paquímetro, para avaliação da evolução do aspecto da lesão cicatricial e morfométrica da ferida feita por análise histológica; as lâminas foram coradas com Hematoxilina–Eosina (HE) e tricrômio de Masson e observaram–se a proliferação vascular, células mononucleares, células polimorfonucleares, proliferação fibroblástica, fibras colágenas e reepitelização. RESULTADOS: Mostraram na macroscopia dos animais do grupo experimento de sete dias que um apresentou pequena quantidade de secreção sem outras alterações dignas de nota; nos animais de 14 dias identificou–se todos com ferida de bom aspecto; nos de 21 dias, foi observada a presença de cicatrização completa em todos os animais. Quanto à análise histológica, houve diferença significativa entre os grupos nas variáveis monocelulares e fibras colágenas em todos os dias, e no 7º dia foi observada diferença significativa na proliferação fibroblástica e reepitelização. CONCLUSÃO: observou–se efeito favorável do extrato aquoso do mesocarpo do babaçu em nível microscópico do processo de cicatrização, nas variáveis mononucleares e fibras colágenas, em todos os dias e entre os grupos.
