RESUMEN

RESUMO: A doença de Kikuchi-Fujimoto ou linfadenite histiocítica necrosante, de curso benigno, é prevalente em mulheres jovens, e associada à febre e leucopenia. Estudos recentes têm demostrado que sua etiologia ainda é incerta, sendo uma doença rara, com incidência de 0,5 a 5% de todas as adenopatias analisadas histologicamente. O diag-nóstico diferencial por imunohistoquímica foi decisivo, descartando outras hipóteses diagnósticas como: linfoma, tuberculose ganglionar e lúpus eritematoso sistêmico. Este relato de caso mostra as características da apresentação da doença em uma mulher, caucasiana e todas as etapas da investigação, destacando a importância dos diagnósticos diferenciais em adenopatias dolorosas e as dificuldades quando avaliamos portadores de doenças raras.

ABSTRACT: Kikuchi-Fujimoto disease or benign necrotizing histiocytic lymphadenitis is prevalent in young women and associated with fever and leukopenia. Recent studies have shown that its etiology is still uncertain, being a rare disease, with an incidence of 0.5 to 5% of all histologically analyzed adenopathies. Differential diagnosis by immunohistochemistry was decisive, ruling out other diagnostic hypotheses such as lymphoma, ganglion tuberculosis, and systemic lupus erythematosus. This case report shows the characteristics of the presentation of the disease in a Caucasian woman and all stages of the investigation, highlighting the importance of differential diagnoses in painful adenopathies and the difficulties when evaluating rare-disease patients.

RESUMEN

OBJECTIVE: To estimate the prevalence of and risk factors for cutaneous lesions of the scrotum and intrascrotal lesions/anomalies among men included in a prostatic cancer screening program in a Brazilian metropolitan city. DESIGN AND SETTING: Cross-sectional study, private outpatient healthcare service. METHODS: 1731 men aged 40 years or over, participating in a prostate cancer screening program conducted by the municipal public employees' healthcare system, underwent systematic urological assessment by a single examiner. RESULTS: The prevalence of scrotal diseases in our sample was 44.7% (773/1731). Tinea cruris occurred in 203 (11.7%) of the participants, with higher risk among diabetics and lower prevalence among nonwhite individuals; scrotal tinea in eight (0.5%), with higher risk among hypertensive men; subcutaneous nodules in 12 (0.7%), especially in individuals with low schooling level; hydrocele in 283 (16.4%), with higher frequency among participants over the age of 60 years, diabetics or individuals with previous histories of nonspecific urethritis; spermatoceles in 174 (10.1%), with greater prevalence among individuals over the age of 60 years or diabetics, and lower frequency among individuals who underwent vasectomy; unilateral testicular hypotrophy/atrophy in 167 (9.7%) and bilateral hypotrophy/atrophy in 93 (5.4%), both occurring more frequently in individuals over the age of 60 years; absence of palpable testicles due to cryptorchidism in 7 (0.4%); and epididymitis/orchitis in 5 (0.3%), with higher prevalence among diabetics. No cases of cancer were identified in this sample. CONCLUSIONS: Scrotal diseases were highly prevalent in this population of Brazilian men.

RESUMEN

PURPOSE: To assess the incidence of testicular necrosis/atrophy immediately after 1 to 4 hours of 1,080-degree torsion of the spermatic cord, and 60 days after detorsion of the spermatic cord. METHODS: 42 rats were divided in 7 groups. Except for the control group, surgical torsion of the right spermatic cord was performed in all groups (T0). After 1, 2, or 4 hours of torsion, each group underwent either ipsilateral orchiectomy (groups OT1, OT2, and OT4), or detorsion of the spermatic cord and observation for 60 days (groups DT1, DT2, and DT4), before they were evaluated for the presence of testicular necrosis/atrophy. RESULTS: Only one rat (5.5%) in groups OT1, OT2, and OT4 had testicular necrosis, in comparison with six rats (33.3%) in groups DT1, DT2, and DT4 (p=0.04). The incidence of testicular necrosis/atrophy was not different between subgroups T1, T2, and T4, and the control group (p>0.05). There was, however, a tendency toward greater incidence of necrosis/atrophy in the rats in group DT4. CONCLUSION: The incidence of testicular necrosis/atrophy immediately after 1 to 4 hours of 1,080-degree torsion of the spermatic cord is 5.5%, in comparison with 33.3% sixty days after detorsion of the spermatic cord.

OBJETIVO: Avaliar a incidência de necrose/atrofia testicular imediatamente após 1 a 4 horas de torção de 1080 graus do cordão espermático e 60 dias após a destorção do cordão espermático. MÉTODOS: 42 ratos foram separados em 7 grupos. Exceto para o grupo controle, todos os animais foram submetidos à torção operatória do cordão espermático direito (T0). Após 1, 2 ou 4 horas de torção, cada grupo foi submetido a orquiectomia ipsilateral (grupos OT1, OT2 e OT4), ou destorção do cordão espermático e observação por 60 dias (grupos DT1, DT2 e DT4), antes de serem avaliados para a presença de necrose/atrofia testicular. RESULTADOS: Somente um rato (5,5 por cento) nos grupos OT1, OT2 e OT4 apresentou necrose testicular em comparação com 6 ratos (33,3%) nos grupos DT1, DT2 e DT4 (p=0,04). A incidência de necrose/atrofia testicular não foi diferente entre os subgrupos T1, T2 e T4 e o grupo controle (p>0,05). Houve, no entanto, uma tendência a maior incidência de necrose/atrofia nos ratos do grupo DT4. CONCLUSÃO: A incidência de necrose/atrofia testicular imediatamente após 1 a 4 horas de torção de 1080 graus do cordão espermático é de 5,5% em comparação com 33,3% sessenta dias após a destorção do cordão espermático.

RESUMEN

OBJECTIVE: To evaluate patients' perception of pain and discomfort during DRE, the impact of discomfort on potential future screening compliance, and if emptying the bladder immediately before DRE reduces patient discomfort. METHODS: One-hundred patients undergoing DRE for prostate cancer screening answered an anonymous questionnaire regarding pain, urinary urgency and bowel urgency during DRE and its potential impact on future examination. Another group with 100 patients was randomized in two subgroups to analyze if urinating immediately before DRE reduces patient discomfort. RESULTS: Seventy-three (73%) patients reported moderate or higher discomfort for at least one of the domains evaluated: 61% complained of pain; 22% of urinary urgency; and 22% of bowel urgency. Emptying the bladder immediately before examination did not reduce pain (58% vs. 50%, p = 0.115), urinary urgency (22% vs. 16%, p = 0.151), or bowel urgency intensity (16% vs. 14%, p = 0.264). There was no difference in the number of patients that answered they will repeat the prostate exam next year (96% vs. 90%, p = 0.211) or in those that would encourage a friend that needs the prostate exam to do it (96% vs. 98%, p = 0.378). CONCLUSIONS: Pain and discomfort during DRE are not negligible but they do not affect intention to have a prostate exam in the future. Urinating immediately before examination does not significantly reduce the incidence of pain, urinary urgency, or bowel urgency during DRE.

RESUMEN

OBJECTIVES: To compare sexual function and satisfaction before and after partial penectomy and to evaluate possible dysfunctions that could modify postoperative sexual functioning. METHODS: A total of 18 patients underwent a personal interview and answered the International Index of Erectile Function questionnaire to determine erectile function, orgasmic function, sexual desire, intercourse satisfaction, and overall satisfaction with sexual life. Domain scores were computed by summing the scores for individual answers, and the final scores were compared before and after partial penectomy. RESULTS: The median patient age was 52 years. The medium penile length after partial penectomy was 4 cm in the flaccid state; 55.6% of patients reported erectile function that allowed sexual intercourse. The main reason for not resuming sexual intercourse appeared to be related to feelings of shame owing to the small penis size and the absence of the glans penis found in 50% of sexually abstinent patients. Surgical complications also compromised the resumption of sexual activity after amputation in 33.3% of these patients. However, 66.7% sustained the same frequency and level of sexual desire as before surgery, and 72.2% continued to have ejaculation and orgasm every time they had sexual stimulation or intercourse. Only 33.3% maintained their preoperative sexual intercourse frequency and were satisfied with their sexual relationship with their partners and their overall sex life. CONCLUSIONS: The preoperative and postoperative scores were statistically different for all domains of sexual function after partial penectomy.

RESUMEN

Persistent müllerian duct syndrome is an unusual disorder characterized by cryptorchidism and retention of müllerian derivatives (uterus, fallopian tubes, and upper vagina). We report the case of a 39-year-old man with this syndrome in association with adenocarcinoma from the retained müllerian remnants of probable endocervical origin. To our knowledge, this is the first report of an endocervical adenocarcinoma associated with persistent müllerian duct syndrome.

RESUMEN

Testicular carcinoids are very rare and account for less than 1% of all testicular neoplasms. They may present as primary testicular tumors or secondary tumors from extratesticular sources. We report a case of a secondary testicular carcinoid occurring 10 years after surgical treatment of an appendiceal carcinoid. The patient underwent radical orchiectomy and at 24 months of follow-up had no evidence of metastases elsewhere. Because secondary carcinoids have a worse clinical course and prognosis than primary tumors, metastatic disease should be excluded before the tumor is identified as a primary. Long-term follow-up is necessary for patients with carcinoid tumor owing to its indolent course and the risk of metastasis several years after treatment of the primary.
