Efficacy of opioids and non-opioid analgesics in the treatment of post procedure pain of burned patients: a narrative review

Abstract Introduction Burns are a common trauma that cause acute severe pain in up to 80% of patients. The objective of this narrative review is to evaluate the efficacy of opioids, non-steroidal anti-inflammatory drugs, paracetamol, gabapentinoids, ketamine, and lidocaine in the treatment of acute pain in burn victims. Methodology The databases explored were PubMed, Embase, ClinicalTrials, and OpenGrey. The included randomized, controlled clinical trials assessed the analgesic efficacy of these drugs on hospitalized patients, had no age limit, patients were in the acute phase of the burn injury and were compared to placebo or other analgesic drugs. Studies describing deep sedation, chronic opioid use, chronic pain, and patients taken to reconstructive surgeries were excluded. The Jadad scale was used to evaluate quality. Results Six randomized controlled clinical trials (397 patients) that evaluated the analgesic efficacy of fentanyl (n = 2), nalbuphine (n = 1), ketamine (n = 1), gabapentin (n = 1), and lidocaine (n = 1) to treat post-procedural pain were included. Fentanyl, nalbuphine, and ketamine were effective, while lidocaine was associated with a slight increase in reported pain and gabapentin showed no significant differences. Two studies were of high quality, one was of medium high quality, and three were of low quality. No studies on the efficacy of NSAIDs or paracetamol were found. Conclusion Evidence of efficacy is very limited. Fentanyl, nalbuphine, and ketamine seem to be effective for controlling acute pain in burn patients, whereas gabapentin and lidocaine did not show any efficacy.

Assessment of main complications of regional anesthesia recorded in an acute pain unit in a tertiary care university hospital: a retrospective cohort

Abstract Background Regional anesthesia has been increasingly used. Despite its low number of complications, they are associated with relevant morbidity. This study aims to evaluate the incidence of complications after neuraxial block and peripheral nerve block. Methods A retrospective cohort study was conducted, and data related to patients submitted to neuraxial block and peripheral nerve block at a tertiary university hospital from January 1, 2011 to December 31, 2017 were analyzed. Results From 10,838 patients referred to Acute Pain Unit, 1093(10.1%) had side effects or complications: 1039 (11.4%) submitted to neuraxial block and 54 (5.2%) to peripheral nerve block. The most common side effects after neuraxial block were sensory (48.5%) or motor deficits (11.8%), nausea or vomiting (17.5%) and pruritus (8.0%); The most common complications: 3 (0.03%) subcutaneous cell tissue hematoma, 3 (0.03%) epidural abscesses and 1 (0.01%) arachnoiditis. 204 of these patients presented sensory or motor deficits at hospital discharge and needed follow-up. Permanent peripheral nerve injury after neuraxial block had an incidence of 7.7:10,000 (0.08%). The most common side effects after peripheral nerve block were sensory deficits (52%) and 21 patients maintained follow-up due to symptoms persistence after hospital discharge. Conclusion Although we found similar incidences of side effects or even lower than those described, major complications after neuraxial block had a higher incidence, particularly epidural abscesses. Despite this, other serious complications, such as spinal hematoma and permanent peripheral nerve injury, are still rare.

Tendinitis cálcica atraumática de tendón extensor común del dedo medio: un caso infrecuente de dolor metacarpofalángico / Atraumatic calcium tendonitis of common extensor tendon of the middle finger: a rare case of metacarpophalangeal pain

Calcific tendinitis is a pathology characterized by the deposits of periarticular hydroxyapatite. Its pathophysiology is not completely known. It is clinically characterized by important inflammatory changes with incapacitating pain. It most commonly affects the shoulder joint and it rarely affects the hand and wrist. Given the unusual nature of this localization, we present the clinical case of a woman who developed calcific tendinitis of the third metacarpophalangeal muscle. We present the clinical evolution of the case, the treatments carried out, and a review of the literature related to this unusual localization of calcific tendinitis.

Principais causas ginecológicas de dor pélvica aguda em mulheres / Main gynecological causes of acute pelvic pain in women

Este trabalho buscou reunir dados essenciais sobre as etiologias de dor pélvica aguda, uma queixa constante nos serviços de emergências e ambulatórios de ginecologia, responsável por grande desconforto e impacto na qualidade de vida de pacientes mulheres. É uma condição laboriosa por causa de seu amplo espectro de causas, devendo ser abordada com cuidado e atenção pelo profissional médico, o qual deve considerar os diversos diagnósticos diferenciais, sendo a ultrassonografia o exame de maior importância para auxiliar em seu diagnóstico. As principais etiologias não obstétricas podem ser não ginecológicas e ginecológicas; essas últimas são divididas em anexiais e uterinas. Entre as causas ginecológicas, devem- -se investigar cistos ovarianos, torções anexiais, leiomiomas, doença inflamatória pélvica, abscesso tubo-ovariano, dismenorreia e complicações de dispositivos intrauterinos. A maioria das causas tem tratamento eficaz, com retorno da função do órgão e melhora da qualidade de vida, sem complicações, especialmente se diagnosticada precocemente.(AU)

The aim of this study was to gather important data on acute pelvic pain etiologies, a usual complaint in the emergency services and gynecology outpatient clinics, responsible for great discomfort and impact on quality of life in female patients. It is a laborious condition due to its wide spectrum of causes, which needs to be approached with attention by the physician, who must consider all the possible diagnoses, being the ultrasonography the most important exam to detect it. The main non-obstetric etiologies can be non-gynecological and gynecological, which are separated in adnexal and uterine causes. Among the gynecological causes, ovarian cysts, adnexal torsions, leiomyomas, pelvic inflammatory disease, ovarian tube abscess, dysmenorrhea and complications of intrauterine devices should be investigated. Most causes can be effectively treated, with return of organ function and improved quality of life, without complications, especially if diagnosed early.(AU)

Nodulos plantares dolorosos tras ejercicio intenso en paciente pediátrica: un reto diagnóstico / Painful nodules on the soles in a pediatric patient: a diagnostic challenge

Resumen: Introducción: La Hidradenitis palmoplantar ecrina idiopática (HPPI) es una dermatosis neutrofílica infrecuente, que cursa con nódulos eritematosos dolorosos de comienzo brusco en regiones plantares o palmoplantares, en niños que no tienen otra enfermedad subyacente. Objetivo: Presentar un caso que ilustra las principales características clínicas e histológicas de la HPPI. Caso Clínico: Niña de 11 años evaluada por nódulos eritematovioláceos dolorosos en planta de pie derecho de 48 horas de evo lución y fiebre de hasta 38,2 °C, sin antecedentes de interés salvo hiperhidrosis y práctica intensa de ejercicio en los días previos. Ante la sospecha clínica de HPPI se realizó biopsia cutánea, que mostró infiltrado inflamatorio neutrofílico alrededor de glándulas sudoríparas ecrinas y abscesos de neutrófilos, confirmando el diagnóstico. Se indicaron antiinflamatorios no esteroidales orales y reposo, con resolución de las lesiones en 7 días. Conclusiones: Este caso demuestra los aspectos más importantes de la HPPI. Esta entidad en muchos casos es infradiagnosticada, dado que puede confundirse con otras patologías que también cursan con nódulos acrales dolorosos, pero tienen distintas implicacio nes patogénicas y terapéuticas. Identificar apropiadamente la HPPI permite evitar la alarma innece saria, tanto en pacientes y sus padres, como en los propios dermatólogos y pediatras.

Abstract: Introduction: Idiopathic Palmoplantar Eccrine Hidradenitis (IPPH) is a rare neutrophilic derma tosis, with painful erythematous nodules of sudden onset in the plantar or palmoplantar region, in children without other underlying diseases. Objective: To present a case that shows the main clinical and histological characteristics of this entity. Clinical Case: 11-year-old girl with a 48-hours history of painful erythematous-violaceous nodules on the right foot plant associated with fever of up to 38.2 °C, with no history of interest except hyperhidrosis and intense exercising on previous days. Given the clinical suspicion of IPPH, a skin biopsy was performed, which showed inflammatory neutrophil infiltration around eccrine sweat glands and neutrophilic abscesses, confirming the diagnosis. Oral NSAIDs and rest were prescribed, with resolution of the lesions in 7 days. Conclusions: This case demonstrates the most important aspects of this entity, in many cases underdiagnosed, since it can be confused with other pathologies that occur with painful acral nodules, but have different pathogenic and therapeutic implications. To properly identify the IPPH allows preventing an unnecessary alarm, both patients and their parents, as in dermatologists and pediatricians themselves.

Calcitonin as an analgesic agent: review of mechanisms of action and clinical applications / Calcitonina como agente analgésico: revisão dos mecanismos de ação e das aplicações clínicas

Abstract Background and objectives: Calcitonin is a polypeptide hormone regulating the metabolism of calcium in the body. For many years calcitonin has been used to maintain and improve bone mineral density and to reduce the fracture rate. Many studies showed that calcitonin had analgesic role in several painful circumstances. This pain-ameliorating effect is irrelevant to its osteoclastic inhibitory effect and mechanisms like altering Na+ channel and serotonin receptor expression or hypothesis including the endorphin-mediated mechanism were used to explain this effect. In this study we performed a thorough review on the role of calcitonin as an analgesic agent in different scenarios and investigated the fact that calcitonin can be a feasible medication to relieve pain. Method: Many studies focused on the analgesic effect of calcitonin in several painful circumstances, including acute pains related to vertebral fractures, metastasis, migraine and reflex sympathetic dystrophy as well as neuropathic pains related to spinal injuries or diabetes, and phantom pain. Also, calcitonin was showed to be a useful additive to local anesthesia in the case of controlling postoperative pain or trigeminal neuralgia more effectively. However we faced some contradictory data for conditions like lumbar canal stenosis, complex regional pain syndrome, phantom pain and malignancies. Conclusion: This study showed that calcitonin could be helpful analgesic agent in different painful situations. Calcitonin can be considered an eligible treatment for acute pains related to vertebral fractures and a feasible alternative for the treatment of the acute and chronic neuropathic pains where other medications might fail.

Resumo Justificativa e objetivos: A calcitonina é um hormônio polipeptídico que regula o metabolismo do cálcio no organismo. Por muitos anos a calcitonina tem sido usada para manter e melhorar a densidade mineral óssea e reduzir a incidência de fraturas. Muitos estudos mostraram que a calcitonina teve efeito analgésico em várias condições físicas de dor. Esse efeito de melhoria da dor é irrelevante diante de seu efeito inibidor osteoclástico e de mecanismos, tais como a alteração do canal de Na+ e da expressão do receptor de serotonina, inclusive a hipótese do mecanismo mediado pela endorfina, que foram usados para explicar esse efeito. Neste estudo, fizemos uma revisão completa sobre o papel da calcitonina como agente analgésico em diferentes cenários e investigamos o fato de que a calcitonina pode ser uma medicação viável para aliviar a dor. Método: Muitos estudos centraram no efeito analgésico da calcitonina em várias condições de dor, inclusive dores agudas relacionadas a fraturas vertebrais, metástases, enxaqueca e distrofia simpática reflexa, bem como dores neuropáticas relacionadas a lesões medulares ou ao diabetes e dor fantasma. Além disso, a calcitonina mostrou ser um aditivo útil à anestesia local para o controle mais efecaz da dor pós-operatória ou neuralgia do trigêmeo. Porém, nos deparamos com alguns dados contraditórios em condições como estenose do canal lombar, síndrome complexa da dor regional, dor fantasma e malignidades. Conclusão: Este estudo mostrou que a calcitonina pode ser um analgésico útil em diferentes condições de dor. A calcitonina pode ser considerada um tratamento elegível para as dores agudas relacionadas a fraturas vertebrais e uma opção viável para o tratamento das dores neuropáticas agudas e crônicas em que outros medicamentos podem falhar.

The influence of the menstrual cycle on acute and persistent pain after laparoscopic cholecystectomy / A influência do ciclo menstrual na dor aguda e persistente após colecistectomia laparoscópica

Abstract Background and objectives: Fluctuations of female sex hormones during menstrual cycle influence pain perception. Endogenous pain inhibition is impaired in follicular phase of menstrual cycle. We tested the primary hypothesis that the women having surgery during their follicular phase have more acute pain and require higher opioids than those in the luteal phase, and secondarily we tested that women who have surgery during their follicular phase have more incisional pain at 3 month postoperatively. Methods: 127 adult females having laparoscopic cholecystectomy were randomized to have surgery during the luteal or follicular phase of their menstrual cycle. Standardized anesthesia and pain management regimen was given to all patients. Pain and analgesic consumption were evaluated in post-anesthesia care unit and every 4 h in the first 24 h. Adverse effects were questioned every 4 h. Time to oral intake and ambulation were recorded. Post-surgical pain, hospital anxiety, depression scale, SF-12 questionnaire were evaluated at 1 and 3 month visits. Results: There was no difference in acute pain scores and analgesic consumption through the 24 h period, Visual Analog Scale at 24 h was 1.5 ± 1.5 cm for follicular group 1.4 ± 1.7 cm for luteal group (p = 0.57). Persistent postoperative pain was significantly more common one and at three month, with an incidence was 33% and 32% in the patients at follicular phase versus 16% and 12% at luteal phase, respectively. The Visual Analog Scale at one and at three month was 1.6 ± 0.7 cm and 1.8 ± 0.8 cm for follicular group and 2.7 ± 1.3 cm and 2.9 ± 1.7 cm in the luteal group (p = 0.02), respectively. There were no significant differences between the groups with respect to anxiety and depression, SF-12 scores at either time. Nausea was more common in follicular-phase group (p = 0.01) and oral feeding time was shorter in follicular phase (5.9 ± 0.9 h) than in luteal phase (6.8 ± 1.9 h, p = 0.02). Conclusions: Although persistent postoperative pain was significantly more common one and three months after surgery the magnitude of the pain was low. Our results do not support scheduling operations to target particular phases of the menstrual cycle.

Resumo Justificativa e objetivos: As flutuações dos hormônios sexuais femininos durante o ciclo menstrual influenciam a percepção da dor. A inibição endógena da dor é prejudicada na fase folicular do ciclo menstrual. Testamos a hipótese primária de que cirurgias em mulheres durante a fase folicular têm mais dor aguda e precisam de mais opioide do que aquelas na fase lútea e a hipótese secundária testada foi que as cirurgias em mulheres durante a fase folicular têm mais dor incisional aos três meses de pós-operatório. Métodos: No total, 127 mulheres adultas submetidas à colecistectomia laparoscópica foram randomizadas para serem operadas durante a fase lútea ou folicular de seus ciclos menstruais. Um regime padronizado para anestesia e tratamento da dor foi administrado a todas as pacientes. A dor e o consumo de analgésico foram avaliados na sala de recuperação pós-anestésica e a cada quatro horas nas primeiras 24 horas. Efeitos adversos foram avaliados a cada quatro horas. Os tempo para ingestão oral e deambulação foram registrados. Dor pós-cirúrgica, ansiedade hospitalar, escala de depressão e questionário SF-12 foram avaliados em visitas feitas no primeiro e terceiro meses. Resultados: Não houve diferença nos escores de dor aguda e no consumo de analgésicos durante o período de 24 horas, Escala Visual Analógica em 24 horas foi de 1,5 ± 1,5 cm para o grupo folicular e 1,4 ± 1,7 cm para o grupo lúteo (p = 0,57). A dor persistente no pós-operatório foi significativamente mais prevalente no primeiro e terceiro mês, com incidência de 33% e 32% nas pacientes em fase folicular versus 16% e 12% na fase lútea, respectivamente. A Escala Visual Analógica no primeiro e terceiro mês foi 1,6 ± 0,7 cm e 1,8 ± 0,8 cm no grupo folicular e 2,7 ± 1,3 cm e 2,9 ± 1,7 cm no grupo lúteo (p = 0,02), respectivamente. Não houve diferença significativa entre os grupos em relação à ansiedade e à depressão, escore SF-12 em ambos os tempos. Náusea foi mais comum no grupo na fase folicular (p = 0,01) e o tempo para alimentação oral foi menor na fase folicular (5,9 ± 0,9 horas) do que na fase lútea (6,8 ± 1,9 horas, p = 0,02). Conclusões: Embora a dor persistente no pós-operatório tenha sido significativamente mais prevalente no primeiro e no terceiro mês após a cirurgia, a magnitude da dor foi baixa. Nossos resultados não apoiam o agendamento de cirurgias tendo como alvo fases específicas do ciclo menstrual.

Profile of Reproductive Issues Associated with Different Sickle Cell Disease Genotypes / Perfil reprodutivo associado aos diferentes genótipos da doença falciforme

Abstract Purpose To describe the reproductive variables associated with different sickle cell disease (SCD) genotypes and the influence of contraceptive methods on acute painful episodes among the women with the homozygous hemoglobin S (HbSS) genotype. Methods A cross-sectional study was conducted between September of 2015 and April of 2016 on 158 women afflicted with SCD admitted to a hematology center in the Northeast of Brazil. The reproduction-associated variables of different SCD genotypes were assessed using the analysis of variance (ANOVA) test to compare means, and the Kruskal-Wallis test to compare medians. The association between the contraceptive method and the acute painful episodes was evaluated by the Chi-square test. Results Themean age of women with SCD was 28.3 years and 86.6% were mixed or of African-American ethnicity. With respect to the genotypes, 134 women (84.8%) had HbSS genotype, 12 women (7.6%) had hemoglobin SC (HbSC) disease genotype, and 12 (7.6%) were identified with hemoglobinopathy S-beta (S-β) thalassemia. The mean age of HbSS diagnosis was lower than that of HbSC disease, the less severe formof SCD (p < 0.001). The mean age ofmenarche was 14.8 ± 1.8 years for HbSS and 12.7 ± 1.5 years for HbSC (p < 0.001). Among women with HbSS who used progestin-only contraception, 16.6% had more than 4 acute painful episodes per year. There was no statistically significant difference when compared with other contraceptive methods. Conclusion With respect to reproduction-associated variables, only the age of the menarche showed delay in HbSS when compared with HbSC. The contraceptive method used was not associated with the frequency of acute painful episodes among the HbSS women.

Resumo Objetivo Descrever as variáveis reprodutivas em diferentes genótipos da doença falciforme (DF) e a influência dos métodos contraceptivos na frequência das crises álgicas em mulheres com homozigose da hemoglobina S (HbSS). Métodos Estudo de corte transversal realizado entre setembro de 2015 e abril de 2016 com 158 mulheres com DF atendidas em um centro de hematologia no Nordeste do Brasil. As variáveis reprodutivas dos diferentes genótipos da DF foram avaliadas utilizando-se o teste de análise de variância (ANOVA) para comparação de médias e o teste de Kruskal-Wallis para comparação de medianas. A associação entre o método contraceptivo e a frequência das crises álgicas foi avaliada pelo teste Qui-quadrado. Resultados A idade média das mulheres com DF foi de 28,3 anos e 86,6% eram afrodescentes. Em relação aos genótipos, 134 mulheres (84,8%) tinham genótipo HbSS, 12 mulheres (7,6%) tinham genótipo para doença da hemoglobina SC (HbSC) e 12 (7,6%) foram identificadas com beta talassemia (S-β). A idade média do diagnóstico de HbSS foi menor do que a da HbSC, sendo esta a forma menos grave da DF (p < 0,001). A idade média da menarca foi de 14,8 ± 1,8 anos para HbSS e de 12,7 ± 1,5 anos para HbSC (p < 0,001). Entre as mulheres com HbSS que fizeram contracepção com progesterona isolada, 16,6% apresentaram mais de 4 episódios de crises álgicas agudas por ano. Não houve diferença estatisticamente significativa quando comparado com outros métodos anticoncepcionais. Conclusão Em relação às variáveis reprodutivas, apenas a idade da menarca apresentou atraso no HbSS em relação ao HbSC. O método anticoncepcional utilizado não foi associado à frequência de crises álgicas entre as mulheres com HbSS.

Cocaine abuse that presents with acute scrotal pain and mimics testicular torsion

ABSTRACT Report case (s) relevant aspects: Man, 27 years old, complaining of acute testicular pain by 2 hours in the remaining left testicle. Denies fever, lower urinary tract symptoms such as dysuria, urinary frequency, concommitant or prior urethral discharge to the painful condition. He underwent right orchiectomy 13 years ago by testicular torsion. He is a chronic user of cocaine for 15 years and during the last three days the drug use was continuous and intense. Proposed premise substantiating case (s) description: Initial diagnostic hypothesis: Syndromic: Acute Scrotum Syndrome (SEA) Main Etiologic (testicular torsion) Secondary Etiologic (acute orchiepididymitis) Briefly delineates what might it add? Lines of research That Could be Addressed: In this challenging clinical case we presented an alternative and new etiologic diangosis for the acute scrotum which the main etiologic factor remains testicular torsion. This new diangosis is acute testicular ischemia as a complication of cocaine abuse.

Abordaje del dolor persistente severo en un niño portador de encefalopatía crónica con trastorno cognitivo / Managing severe persistent pain in children suffering from chronic encelopathy with cognitive impairment

El dolor es un problema frecuente y significativo en niños portadores de encefalopatía crónica con trastorno cognitivo. Esta población es muy vulnerable a la falta de reconocimiento y tratamiento del dolor. Habitualmente pueden presentar múltiples fuentes y mecanismos de dolor, nociceptivo como resultado de lesión tisular e inflamación y neuropático por lesión, disfunción o alteración del sistema nervioso. Pueden asociar problemas como: espasticidad, disautonomías, distonías, considerados fuentes adicionales de incomodidad, que deben ser tenidos en cuenta para guiar el tratamiento. El uso de escalas validadas puede contribuir a una mejor objetivación de la intensidad. Un protocolo basado en guías internacionales que integre medidas farmacológicas, apoyado por terapias no farmacológicas conforma una estrategia integral para el alivio de dolor en esta población.

Pain is a common and significant problem in children with chronic encephalopathy with cognitive impairment. This population is very vulnerable to the lack of recognition and undertreatment of pain. Usually they may have multiple sources and mechanisms of pain, nociseptive as a result of tissue damage and inflammation and neuropathic injury, dysfunction or disorder of the nervous system. They may have associated problems such as spasticity, dysautonomia, dystonias, considered additional sources of discomfort, which must be included to guide treatment. The use of validated scales can contribute to a better evaluation of intensity. A protocol based on international guidelines that integrates pharmacological measures, supported by non-pharmacological therapies presents an integral strategy for the relief of pain in this population.

Tumores de testículo em crianças e adolescentes / Testicular tumors in children and adolescents

OBJETIVO: Avaliar comparativamente aspectos clínicos e epidemiológicos dos tumores de testículo na infância e adolescência. MÉTODOS: Análise retrospectiva dos prontuários de pacientes com neoplasias de testículo ou paratesticulares. Foram classificados como crianças os menores de 10 anos e como adolescentes os pacientes entre 10 e 20 anos. Os resultados obtidos foram comparados por meio do teste para duas proporções: teste não paramétrico de Mann-Whitney e teste de log-rank. RESULTADOS: No período de janeiro de 1992 a julho de 2009, foram admitidos 60 pacientes: 34 crianças e 26 adolescentes com neoplasias de testículo ou paratesticulares. As principais manifestações foram tumor e dor na bolsa escrotal. A queixa de dor foi mais comum em adolescentes (p = 0,006). Estes apresentaram tempo médio de história de 4,9 meses, mais prolongado do que crianças, com 2,3 meses (p = 0,01). Os tipos histológicos encontrados foram: tumores de células germinativas em 32/60 (53 por cento), rabdomiossarcomas (RMSs) em 23/60 (38,3 por cento) e outros em 5/60 (8,3 por cento). Os adolescentes apresentaram maior frequência de RMSs, metástases em linfonodos (p = 0,003) e a distância (p = 0,035). As diferenças na sobrevida dos pacientes estudados não foram estatisticamente significantes, havendo apenas indicativo de que a sobrevida, nos casos de RMS, é maior nas crianças (p = 0,072). CONCLUSÕES: Os adolescentes com tumor testicular apresentaram maior tempo de história, tipo histológico agressivo e doença avançada ao diagnóstico quando comparados às crianças, a despeito da pequena amostra.

OBJECTIVE: To perform a comparative assessment of the clinical and epidemiological aspects of testicular tumors in childhood and adolescence. METHODS: Retrospective analysis of medical records of patients with testicular or paratesticular neoplasms. Patients under 10 years were classified as children and patients between 10 and 20 were classified as adolescents. The obtained results were compared through the two-sample test for proportions: non-parametric Mann-Whitney test and log-rank test. RESULTS: 60 patients were admitted in the period from January 1992 to July 2009: 34 children and 26 adolescents with testicular or paratesticular neoplasms. The main manifestations were testicular tumor and scrotal pain. Pain complaints were more common in adolescents (p = 0.006), who presented a mean time from disease onset to diagnosis of 4.9 months, longer than children, who presented a period of 2.3 months from disease onset to diagnosis (p = 0.01). Histological types were as follows: germ cell tumors in 32/60 (53 percent), rhabdomyosarcomas (RMSs) in 23/60 (38.3 percent), and other in 5/60 (8.3 percent). Adolescents presented a higher incidence of RMSs, lymph node metastases (p = 0.003) and distant metastases (p = 0.035). Differences in survival rates among the studied patients were not statistically significant, the only indicative being that survival in RMS cases is longer for children (p = 0.072). CONCLUSIONS: Compared to children, adolescents with testicular tumor presented longer time from disease onset to diagnosis, aggressive histological type and advanced illness at diagnosis, despite the small sample analyzed.

Shear-Wave Elastography of Segmental Infarction of the Testis

Segmental testicular infarction (STI) is a rare cause of acute scrotum. The spectrum of findings on gray-scale and color Doppler ultrasonography differ depending on the time between the onset of testicular pain and the ultrasonography examination. We are not aware of the usefulness of shear-wave elastography for the diagnosis of STI. We report the shear-wave elastography features in a case of STI and discuss the role of this diagnostic modality in the differential diagnosis.
