Psychological Morbidity in Endometriosis: A Couple's Study.

Endometriosis is a chronic gynecological disease that impacts more than 176 million women worldwide, having a strong impact on psychological morbidity. This study aimed to evaluate the contribution of psychological morbidity, in women with endometriosis, taking into consideration the duration of the couple's relationship and the duration of the disease and also examined whether women's sexual satisfaction had an impact on their psychological morbidity (actor effect) and on their sexual partners' psychological morbidity (partner effect) and vice versa. Participants were 105 women and their partners, who answered the Hospital Anxiety and Depression Scale (HADS); Couple Satisfaction Index (CSI-4) and the Global Measure of Sexual Satisfaction (GMSEX). The results revealed a direct effect between the perception of symptom severity, marital satisfaction, and women's psychological morbidity. Sexual activity and the presence of infertility had an indirect effect on the relationship between sexual satisfaction, diagnosis duration, and psychological morbidity, respectively. Finally, women's sexual satisfaction had a direct effect on their own and their partner's marital satisfaction that predicted less psychological morbidity, in both. Thus, a multidisciplinary intervention focused on the couple's sexual and marital relationship is needed to promote psychological well-being in this population.

Demonstration of Isthmocele Surgical Repair.

STUDY OBJECTIVE: To describe the surgical treatment of a uterine isthmocele. DESIGN: Demonstration of the laparoscopic technique with narrated video footage. SETTING: Cesarean section rate has been increasing despite the World Health Organization's recommendation of a maximum 15%, with some countries reaching rates as high as 50%. The choice of delivery method is a complex topic based on physical and psychologic health, social and cultural context, and quality of maternity care. With the increasing number of cesarean sections, a new entity was recognized, the isthmocele [1]. A uterine isthmocele is a dilatation of the uterine cesarean scar and functions as a reservoir collecting blood during menstruation. Isthmocele prevalence ranges from 19% to 84%[2]. The most frequent complaint relates to intermittent postmenstrual bleeding (30%). Isthmocele can be a cause of infertility and pelvic pain [3]. Interstitial pregnancy is a known complication with a mortality rate up to 2.5%. The diagnosis can be made by transvaginal ultrasound and/or magnetic resonance imaging but also by hysteroscopy or hysterosalpingography. Treatment can be done by controlling the symptoms with oral combined contraceptive (decreasing metrorrhagia) or with surgical correction improving symptoms and/or fertility [4-7]. Isthmocele correction seems to improve secondary infertility in patients in whom a fertility workup did not find other cause [8,9]. Surgical approach can be done by vaginal route with hysteroscopy; abdominal route with laparoscopy, robotic or laparotomy; or through a combine procedure with both routes. Hysterectomy is the definitive treatment, but for those who want to preserve fertility, isthmocele correction can be offered. For laparoscopic surgery, several ways have been described to detect the isthmocele such as Foley catheter, hysteroscopy, methylene blue, and Hegar probe. When we do laparoscopy, we prefer concomitant use of hysteroscopy. There is a trending opinion that patients with a smaller isthmocele could be treated hysteroscopically (2.5 mm according to Jeremy et al [10] and 3.0 mm described by Marotta et al [11]). The goal of hysteroscopy correction is to remove the inflammatory infiltration in the endocervix, cutting the superior and inferior edges of the defect enabling normal blood evacuation of the uterus. By contrast, those with a larger isthmocele (with <2.5-3.0-mm residual myometrium) and a risk of perforation during hysteroscopy could be better treated by laparoscopy. This is especially important in patients interested in pregnancy because of the risk of uterine perforation [12]. There is still no strong evidence that hysteroscopic correction leads to an increased number of uterine ruptures compared with laparoscopy, but myometrium thickness seems to be greater after laparoscopic correction. Myometrium thickness is an independent risk factor for uterine rupture [13], and therefore, laparoscopic correction is preferred over hysteroscopic in women with a pregnancy desire. Finally, after surgical correction of an isthmocele, we recommend a 6-month interval before attempting pregnancy. INTERVENTIONS: Laparoscopic treatment is important in women who are symptomatic, have thin endometrium, and desire a pregnancy. Key strategies are (1) dissection of the vesicouterine pouch laterally to avoid entering the bladder wall; (2) transillumination with hysteroscopy; (3) cut with cold scissors avoiding thermal damage of remaining myometrium; and (4) suture with figure 8 in multiple layers. No evidence of using a specific suture is available. CONCLUSION: Surgical treatment of a uterine isthmocele is a good option in women who are symptomatic and infertile. Laparoscopic treatment guided by hysteroscopy is a good option if residual myometrium is <3 mm.

Successful Treatment of Endometriosis-Related Hemorrhagic Ascites: A Report of Three Cases.

Endometriosis-related ascites is rare and is frequently confused with an ovarian malignancy. Since it affects women in reproductive age, its diagnosis and therapy are even more challenging. These patients usually present with abdominal distension, pelvic pain, and weight loss, but a careful questioning usually reveals the typical endometriosis symptoms-such as dysmenorrhea and dyspareunia. We present three cases of endometriosis-related ascites, one of them with pleural effusion. All cases were associated with extensive disease and required laborious laparoscopic surgery, medical therapy with gonadotropin releasing hormone analogs, and long-term follow-up. One of the patients delivered twins following an in vitro fertilization (IVF) cycle without recurrence of ascites. We aim to raise awareness toward the importance of considering endometriosis in a patient with ascites of unknown origin.

Cutaneous Morbidity Among Inflammatory Bowel Disease Patients: A Cohort Study.

BACKGROUND AND AIMS: Patients with inflammatory bowel diseases are prone to cutaneous manifestations. The aim of this study was to investigate their prevalence, type and association to demographic and clinical factors. METHODS: This was a cross-sectional study. Information relative to patients of a central Portuguese hospital with a definitive diagnosis of an inflammatory bowel disease, who were prospectively recruited, was collected. RESULTS: The final cohort included 342 patients, 62% of whom had Crohn's disease and 38% had ulcerative colitis. Cutaneous extraintestinal manifestations were present in 44.4% of all patients; this prevalence was lower [14.9%] when excluding cutaneous manifestations secondary to nutrition deficiency or drugs. These skin lesions were classified as granulomatous [0.3%], reactive [4.4%], immunologically associated [10.5%] and secondary to nutritional deficiencies [6.4%] or to bowel-related therapy [29.5%]. Excluding those secondary to nutrition or drugs, cutaneous manifestations were significantly associated with females (odds ratio [OR] 3.210 [1.625-6.340], p = 0.001) and younger patients (OR 0.954 [0.924-0.985], p = 0.004). Additionally, their occurrence was related to patients up to 16 years (OR 13.875 [1.332-144.484], p = 0.028) among the Crohn's disease sub-cohort, whereas in the ulcerative colitis sub-cohort they were more likely to occur in patients with extensive colitis (OR 5.317 [1.552-18.214], p = 0.008). CONCLUSIONS: Nearly half of the patients analysed had at least one cutaneous extraintestinal manifestation. The fact that certain lesions tend to be more common among patients with defined characteristics should alert the physicians and allow an early diagnosis and, when pertinent, a reference to dermatology.

Obturator Internus Muscle Endometriosis with Nerve Involvement: a Rare Clinical Presentation.

STUDY OBJECTIVE: To describe our surgical approach in a rare case of deep infiltrating endometriosis of the obturator internus muscle with obturator nerve involvement. DESIGN: A step-by-step surgical explanation using video and literature review (Canadian Task Force Classification III). SETTING: Endometriosis can be pelvic or rarely extrapelvic and is classically defined as the presence of endometrial glands and stroma outside the uterine cavity [1,2]. Pain along the sensitive area of the obturator nerve, thigh adduction weakness and difficulty in ambulation are extremely rare presenting symptoms [2-4]. PATIENT: We report a case of a 32-year-old patient who presented with cyclic leg pain in the inner right thigh radiating to the knee caused by a cystic endometriotic mass in the obturator internus muscle with nerve retraction. The patient provided informed consent to use the surgical video. Institutional review board approval was obtained. INTERVENTIONS: Pelvic magnetic resonance imaging was performed and confirmed a nodular lesion of about 2.3 cm with high signal on T1WI and T2WI and without fat suppression on T2FS inside the right obturator internus muscle, suggesting an endometriotic lesion (Fig. 1). Surgical removal of the mass was performed using the laparoscopic approach. A normal pelvic cavity was found, and the retroperitoneal space was dissected. A mass located within the right obturator internus muscle, below the right iliac external vein, behind the corona mortis vein, and lateral to the right obturator nerve was identified. The whole region was inflamed, and the nerve was partially involved. Dissection was performed carefully with rupture of the tumor, releasing a chocolatelike fluid (Fig. 2), and the cyst was removed. Pathology examination was consistent with endometriosis. Patient improvement was observed, with pain relief and improved ability for right limb mobilization. No recurrence of endometriosis was found at the follow-up visit 6 months later. MEASUREMENTS AND MAIN RESULTS: The obturator nerve is responsible for motor and sensitive innervation of the joins and internal muscles of thigh and knee as well as the innervation of skin in the internal thigh. Pain along the sensitive area of the obturator nerve at the time of menstruation, thigh adduction weakness, difficulty ambulating, or paresthesia can be presenting symptoms with the involvement of the obturator nerve [5]. Besides paresthesia, our patient presented all the symptoms. The suspected diagnosis of obturator internus muscle endometriosis with retraction of the obturator nerve was confirmed by laparoscopic surgery and pathological examination of the excised tissue. To our knowledge, only 4 cases of endometriosis involving the obturator nerve have been described (according to MEDLINE searched in January 2017) [5-8]. The laparoscopic approach provided an excellent access to the retroperitoneal space, allowing fine dissection of the obturator nerve and the surrounding structures with complete removal of the cystic mass. CONCLUSION: We report a rare case of endometriosis with a single mass located inside the right obturator internus muscle with neuronal involvement of the obturator nerve. The fundamental role of laparoscopy was clearly demonstrated for the diagnosis and treatment of our patient.

Treatment for Uterine Isthmocele, A Pouchlike Defect at the Site of a Cesarean Section Scar.

An isthmocele appears as a fluid pouchlike defect in the anterior uterine wall at the site of a prior cesarean section and ranges in prevalence from 19% to 84%, a direct relation to the increase in cesarean sections performed worldwide. Many definitions have been suggested for the dehiscence resulting from cesarean sections, and we propose standardization with a single term for all cases-isthmocele. Patients are not always symptomatic, but symptoms typically include intermittent abnormal bleeding, pain, and infertility. Pregnancy complications that result from an isthmocele include ectopic pregnancy, low implantation, and uterine rupture. Magnetic resonance imaging and transvaginal ultrasound are the gold standard imaging techniques for diagnosis. Surgical treatment of an isthmocele is still a controversial issue but should be offered to symptomatic women or the asymptomatic patient who desires future pregnancy. When surgery is the treatment choice, laparoscopy guided by hysteroscopy, hysteroscopy alone, or vaginal repair are the best options depending on the isthmocele's characteristics and surgeon expertise.

MRI for adenomyosis: a pictorial review.

Adenomyosis is defined as the presence of ectopic endometrial glands and stroma within the myometrium. It is a disease of the inner myometrium and results from infiltration of the basal endometrium into the underlying myometrium. Transvaginal ultrasonography (TVUS) and magnetic resonance imaging (MRI) are the main radiologic tools for this condition. A thickness of the junctional zone of at least 12 mm is the most frequent MRI criterion in establishing the presence of adenomyosis. Adenomyosis can appear as a diffuse or focal form. Adenomyosis is often associated with hormone-dependent lesions such as leiomyoma, deep pelvic endometriosis and endometrial hyperplasia/polyps. Herein, we illustrate the MRI findings of adenomyosis and associated conditions, focusing on their imaging pitfalls. TEACHING POINTS: • Adenomyosis is defined as the presence of ectopic endometrium within the myometrium. • MRI is an accurate tool for the diagnosis of adenomyosis and associated conditions. • Adenomyosis can be diffuse or focal. • The most established MRI finding is thickening of junctional zone exceeding 12 mm. • High-signal intensity myometrial foci on T2- or T1-weighted images are also characteristic.

Abdominal Wall Endometriosis Excision with Mesh Closure - Report of Two Cases.

Abdominal wall endometriosis (AWE) is a rare condition included in the differential diagnosis of an abdominal wall mass and/or pelvic pain in women of reproductive age. It usually occurs after pelvic surgery, most commonly caesarean section. Given the variable clinical presentation, diagnosis can be challenging if a high index of suspicion for AWE does not exist. Consequently, the correct diagnosis is often missed in the preoperative assessment. The presence of endometriosis in other locations can aid in the diagnosis, but other endometriotic lesions do not always exist. Image studies, particularly ultrasound and magnetic resonance imaging, can also be of help in the differential diagnosis. Even though new management techniques such as ultrasound-guided percutaneous cryoablation seem to be promising, surgical excision is still the mainstay of treatment. When the aponeurosis is involved, lesion excision might need to be followed by wall closure with the use of a mesh to lessen tissue tension. We present two typical cases of AWE after caesarean section, one of them recurrent, in patients with concurrent endometriosis of other locations. Total lesion excision followed by polypropylene mesh closure has been performed, with very good post-operative outcomes. We aim to raise awareness towards this diagnosis and to highlight the importance of complete lesion excision and adequate closure of the abdominal wall.

Laparoscopic Psoas Hitch Double Ureteral Re-implantation in the Duplex Urinary System for Treatment of Ureterovaginal Fistula.

INTRODUCTION: Although laparoscopy is widely established for ablative urologic procedures, pelvic reconstructive procedures are still mostly performed by open-surgery. As urologists continue to introduce advanced laparoscopic skills to reconstructive urologic procedures, we present our experience with a laparoscopic psoas hitch double ureteral re-implantation in a patient with an ureterovaginal fistula and an ipsilateral duplex urinary system. MATERIALS AND METHODS: A 42-year-old patient presented with continuous involuntary urine loss from the vagina after an abdominal hysterectomy. A double modified Lich-Gregoir ureteral re-implantation with a psoas hitch was performed, using a 4-port laparoscopic approach. RESULTS: There were no post-operative complications and the cystography at post-operative day 14 revealed good positioning of the psoas hitch, with no leak or reflux. At three-months follow-up, the patient is completely dry and asymptomatic. CONCLUSION: Laparoscopic ureteroneocystostomy with psoas hitch for the treatment of lesions of the distal ureter is a possible, safe, and effective way to resolve a complex urologic situation with minimally invasive surgery. Laparoscopy is becoming the standard approach to urologic pelvic reconstructive procedures, even in the most complex cases.

Laparoscopic Neurolysis of Deep Endometriosis Infiltrating Left Femoral Nerve: Case Report.

Pelvic endometriosis may infiltrate somatic nerves causing severe neuropathic symptoms with a high impact on quality of life. It is a medical condition poorly known, and few published data about involvement of femoral nerve are available. We report an isolated unilateral endometriosis lesion of the left lumbar region infiltrating the femoral nerve in a 38-year-old woman. She described severe dysmenorrhea, dyspareunia, dischezia, and chronic pelvic pain with irradiation to the anterior part of the left thigh. After investigation, it was identified as a 5-centimeter endometriotic nodule involving the femoral nerve and the psoas muscle. The patient was treated by two laparoscopic surgeries with neurolysis of the involved somatic nerve by a multidisciplinary team, with improvement of the symptoms. Laparoscopic neurolysis is the first approach advocated in these cases, leading to relief of neurological symptoms resulting from nerve infiltration by endometriosis.

Validation of the Portuguese Version of EHP-30 (The Endometriosis Health Profile-30).

INTRODUCTION: Endometriosis Health Profile Questionnaire-30 is currently the most used questionnaire for quality of life measurement in women with endometriosis. The aim of this study is to evaluate the psychometric properties and to validate the Portuguese Endometriosis Health Profile Questionnaire-30 version. MATERIAL AND METHODS: A sequential sample of 152 patients with endometriosis, followed in a Portugal reference center, were asked to complete a questionnaire on social and demographic features, the Portuguese version of the Endometriosis Health Profile Questionnaire-30 and of the Short Form Health Survey 36 Item â version 2. Appropriate statistical analysis was performed using descriptive statistics, factor analysis, internal consistency, item-total correlation and convergent validity. RESULTS: Factorial analysis confirmed the validity of the five-dimension structure of the Endometriosis Health Profile Questionnaire-30 core questionnaire, which explained 83.2% of the total variance. All item-total correlations presented acceptable results and high internal consistency, with Cronbach's alpha ranging between 0.876 and 0.981 for the core questionnaire and between 0.863 and 0.951 for the modular questionnaire. Significant negative associations between similar scales of Endometriosis Health Profile Questionnaire-30 and Short Form Health Survey 36 Item â version 2 were demonstrated. Data completeness achieved was high for all dimensions. The emotional well-being scale in the core questionnaire and the infertility scale in the modular section had the highest median scores, and therefore the most negative impact on the quality of life of participating women. DISCUSSION: The test-retest reliability and responsiveness of the questionnaire should be evaluated in future studies. CONCLUSION: The present study demonstrates that the Portuguese version of the Endometriosis Health Profile Questionnaire-30 is a valid, reliable and acceptable tool for evaluating the health-related quality of life of Portuguese women with endometriosis.

Demonstrou-se associação negativa significativa entre as dimensões similares do Endometriosis Health Profile Questionnaire-30 e do Short Form Health Survey36 Itemâversão 2. A taxa de preenchimento do questionário foi elevada para todas as dimensões. A perda do bem-estar emocional (no questionário central) e a infertilidade (no modular) apresentaram as pontuações médias mais elevadas e, consequentemente, impacto mais negativo sobre a qualidade de vida.Discussão: São necessários estudos para avaliar a fiabilidade teste-reteste e a sensibilidade à mudança desta versão portuguesa do Endometriosis Health Profile Questionnaire-30.Conclusão: Este estudo demonstra que a versão portuguesa do Endometriosis Health Profile Questionnaire-30 é um instrumento adaptado, validado e bem aceite para a avaliação da qualidade de vida das mulheres portuguesas com endometriose.

Oral Lichen Planus in IBD Patients: A Paradoxical Adverse Effect of Anti-TNF-α Therapy.

INTRODUCTION AND AIMS: The efficacy of tumor necrosis factor alpha (TNF-α) inhibitors in the treatment of Inflammatory Bowel Disease (IBD) is well established. Many cutaneous and mucosal lesions have been described under anti-TNF-α therapy, some of them being considered as paradoxical. In this series we aimed to review the cases of oral lichen planus (OLP) in IBD patients under treatment with anti-TNF-α agents. METHODS: Histologic findings from oral lesions of IBD patients treated with anti-TNF were revised. RESULTS: Three female patients with IBD developed oral lichen planus (OLP) after starting anti-TNF-α therapy. Other etiologies were excluded. CONCLUSIONS: In light of the increasing use of TNF-α inhibitors the occurrence of OLP is a potentially emerging side effect, thus we recommend a careful monitoring for oral manifestations in IBD patients treated with anti-TNF-α agents.

[Total laparoscopic hysterectomy: retrospective analysis of 262 cases]. / Histerectomia totalmente laparoscópica: análise retrospetiva de 262 casos.

INTRODUCTION: Hysterectomy is one of the most common gynecological procedures and may be performed either by vaginal approach, laparotomy or laparoscopy. Although total laparoscopic hysterectomy has multiple advantages, conflicting major complication rates have been previously reported. OBJECTIVES: To describe our experience performing TLH and to evaluate complication rates. MATERIAL AND METHODS: A retrospective observational study of all total laparoscopic hysterectomy performed in our department, by the same surgical team, between April 2009 and March 2013 (n = 262), was conducted. Medical records were reviewed for patient characteristics, operating time, uterine weight, post-operative hemoglobin variation, length of hospital stay, and intra and postoperative complications. RESULTS: Patient average age was 48.9 ± 9.0 years and 49.2% had previous abdominopelvic surgery. The average body mass index was 26.5 ± 4.5 kg/m(2) and 42% of women were either overweight or obese. The mean operating time during the total study period was 77.7 ± 27.5 minutes, but it decreased significantly as the surgical team's training increased. Average uterine weight was 241.0 ± 168.4 g and average hospital stay was 1.49 ± 0.9 days. The mean postoperative hemoglobin variation was -1.5 ± 0.8 g/dL. The major and minor complication rates were 1.5% (n = 4) and 11.5% (n = 30), respectively. One procedure was converted to laparotomy and two women had a vaginal vault dehiscence. No important urinary tract or bowel injuries occurred. CONCLUSIONS: This study demonstrates that, in experienced hands, total laparoscopic hysterectomy is safe and with low complications rates.

Introdução: A histerectomia é a cirurgia ginecológica major mais frequentemente realizada nos países desenvolvidos, considerando-se três principais vias de abordagem: vaginal, abdominal e laparoscópica. Apesar de múltiplas vantagens, a histerectomia totalmente laparoscópica tem-se associado a controvérsia relativamente à taxa de complicações.Objectivos: Análise da nossa casuística de histerectomia totalmente laparoscópica e avaliação da taxa de complicações.Material e Métodos: Análise retrospetiva dos processos clínicos das doentes submetidas a histerectomia totalmente laparoscópica no nosso departamento, pela mesma equipa cirúrgica, entre abril de 2009 e março de 2013 (n = 262).Resultados: As doentes tinham em média 48,9 ± 9 anos e 49,2% tinha antecedentes de cirurgia abdomino-pélvica. O índice de massa corporal médio era 26,5 ± 4,5 kg/m2, sendo que 42% eram obesas ou tinham excesso de peso. O tempo operatório médio para realização da histerectomia totalmente laparoscópica foi 77,7 ± 27,5 minutos, diminuindo significativamente com o aumento da experiência da equipa cirúrgica. O peso médio da peça operatória foi 241 ± 168,4g e a duração média do internamento após a cirurgia foi 1,49 ±0,9 dias. A diferença entre a hemoglobina pré e pós-operatória foi 1,5 ± 0,8g/dL. A morbilidade major foi 1,5% (n = 4) e a minor 11,5% (n = 30). Salienta-se um caso de conversão para laparotomia e dois casos de deiscência da cúpula vaginal. Não ocorreu nenhuma lesão urinária ou gastrointestinal grave.Conclusões: Esta série demonstra que, se realizada por uma equipa cirúrgica adequadamente treinada, a histerectomia totalmente laparoscópica é segura e associada a baixa taxa de complicações.

Laparoscopic re-anastomosis of a uterine avulsion following cold-knife conization.

This report presents an exceptional case of uterine avulsion following a cold-knife conization, an unprecedented surgical complication of a common gynecological procedure. Furthermore, it describes the outcomes of the conservative laparoscopic reconstruction that was performed. A 30-year-old nulliparous was referred to our department with secondary amenorrhea and cyclic pelvic pain following a cold-knife conization performed 9 months previous in another institution. The patient underwent a diagnostic laparoscopy, which confirmed that the cervix had been completely resected and that the uterine and vaginal cavities were no longer in contact. We performed an end-to-end utero-vaginal anastomosis followed by a prophylactic cerclage. No intraoperative or postoperative complications were observed. One month after surgery the patient was asymptomatic with normal withdrawal bleeding and remained asymptomatic during her 12-month follow-up consult. To our knowledge, this is the first time that this serious complication with a potential for irreversible damage to reproductive function is reported as a complication of cervical conization. Although our conservative surgical correction repaired the anatomy and reestablished menstruation outflow, further follow-up is necessary to confirm the extent to which reproductive function was restored.

Infliximab in psoriasis and psoriatic arthritis.

Psoriasis is a chronic inflammatory disorder of the skin and joints. Although rarely life threatening, psoriasis can significantly impair quality of life (QOL) and cause considerable physical and psychological distress. Between 6 and 42% of patients with psoriasis develop psoriatic arthritis, which is characterized by stiffness, pain, swelling and tenderness of the joints. Nail psoriasis is highly prevalent in both plaque-type psoriasis and psoriatic arthritis and is found in approximately 50% of patients with psoriasis and in 80% of patients with psoriatic arthritis. Infliximab, a chimeric human-murine monoclonal antibody directed against tumour necrosis factor α, is approved in the USA and EU for the treatment of plaque psoriasis and psoriatic arthritis at a recommended dosage of 5 mg/kg administered by intravenous infusion at 0,2 and 6 weeks, then every 8 weeks thereafter. The EXPRESS and EXPRESS II trials demonstrated that infliximab is efficacious as induction and maintenance therapy in the treatment of moderate to severe plaque psoriasis and also improved health-related QOL. Infliximab is also efficacious in the treatment of psoriatic arthritis, as shown in the IMPACT and IMPACT II studies. Infliximab is generally well tolerated, with a similar adverse event profile in both psoriasis and psoriatic arthritis. The use of infliximab in three case reports is presented. The patients are similar to those normally seen by clinicians, and include a male patient with plaque psoriasis and a history of severe psoriatic arthritis who was corticosteroid dependent and in whom other systemic treatments were not effective or were not able to be used. This patient showed a rapid response to infliximab with no skin lesions or arthritis after 7 weeks' treatment. Infliximab was also safe and effective in the treatment of a female patient with plaque and nail psoriasis and a history of psoriatic arthritis. Importantly, this case report supports the efficacy of infliximab in psoriatic nail disease in the context of severe skin and joint involvement. Case 3 describes a young male patient with moderate plaque-type psoriasis associated with severe nail involvement and early signs of psoriatic arthritis. Treatment with infliximab improved nail psoriasis and appears to be an effective biological treatment for nail psoriasis. Importantly, ultrasound was able to diagnose joint involvement, as seen from the proliferative synovitis in the distal interphalangeal joint and mild enthesitis, despite there being no clinical evidence of psoriatic arthritis. This case report highlights the importance of early screening. If such abnormalities are detected early on in the course of psoriasis, clinicians may be able to predict which patients are more likely to develop psoriatic arthritis, and therefore offer effective and long-term treatment that may reduce the disability and impairment of daily activities that can be associated with psoriatic arthritis.

Pili annulati--what about racial distribution?

Pili annulati is a rare hair shaft abnormality and, as far as we know, there are no published data on pili annulati's racial distribution. To our knowledge, this is the first case reported in an African-American patient.

[Scrotal ulcers revealing pulmonary and genitourinary tuberculosis]. / Úlceras escrotais reveladoras de tuberculose pulmonar e genito-urinária.

A 76-year-old male patient with an angioimmunoblastic T-cell lymphoma under treatment with fludarabine was referred because of scrotal ulcers, evolving for several months. Respiratory, gastrointestinal, and urinary symptoms were denied. Histopathological examination showed the presence of a chronic inflammatory process with epithelioid granulomas. Ziehl-Neelsen stain was positive for acid-fast bacilli. PCR analysis allowed the identification of a mycobacteria strain belonging to the Mycobaterium tuberculosis complex. Skin biopsy was repeated and culture revealed M. tuberculosis sensitive to traditional tuberculostatic drugs. This bacteria was also isolated in bronchial and urinary specimens. Although no abnormal findings were detected on chest radiography or abdominal ultrasonography, scrotal ultrasound showed areas of nodular thickening in the lower part of the epididymis. The diagnosis of cutaneous, lung, and genitourinary tuberculosis was made and the patient was treated with multidrug therapy (rifampicin 600 mg/day, isoniazid 250 mg/day, pyrazinamide 1500 mg/day, and ethambutol 1200 mg/day for the first 2 months, followed by rifampicin and isoniazid with the same dosages for the subsequent 7 months). Complete resolution of skin lesions was observed after two months of treatment. Diagnosis and treatment modalities are discussed. This case emphasizes the importance of considering tuberculosis in the differential diagnosis of genital ulcer.
