Diagnostic accuracy of Doppler ultrasound technique of the penile arteries in correlation to selective arteriography

In 63% of 265 patients with erectile dysfunction a relevant arterial inflow disturbance was found by Doppler ultrasound examination. Correlation between Doppler and arteriography in 58 patients showed an accuracy of 95% in detecting penile arteries and an accuracy of 91% in discovering a pathological arterial pattern (arterial anomaly or arteriosclerotic obstruction). In 15 patients the arterial inflow was measured additionally by Doppler ultrasound technique after intracavernosal injection of vasoactive drugs (IIVD) (7.5 mg papaverine and 0.25 mg phentolamine). This technique proved to be more reliable than in the flaccid state and markedly facilitated localization and assessment of pathological changes of the cavernosal arteries

Colonic atresia and anorectal malformation in a Haitian patient: a case study of rare diseases

Introduction: Colonic atresia and anorectal malformation are rare congenital anomalies individually. Few reports of the conditions combined in a single patient have been published in the literature. Neither colonic atresia, anorectal malformation or a combination of the disorders has previously been reported in the Haitian population. Case presentation: A 5-day-old female presented with feculent emesis, failure to pass stool since birth and an imperforate and stenotic anus. Exploratory laparotomy revealed colorectal atresia distal to a malformed cecum and a Wingspread low subtype anorectal malformation without any associated urogenital fistulae. Temporizing percutaneous ileal drainage was followed by second-stage anal perforation and dilation, ileal J-pouch and pull through. Discussion: This is the first reported case of colonic atresia, anorectal malformation or the combination of the disorders among the Haitian population and one of only a handful of such cases reported worldwide. Although vascular accidents in utero have been implicated as the etiology of colonic atresia, simultaneous presence of anorectal malformation suggests a multifactorial cause. Investigation for multisystem abnormalities is warranted. Two-staged operative correction is considered the best treatment; however, long-term postoperative outcomes are uncertain. Conclusion: The coexistence of colonic atresia and anorectal malformation is a very rare occurrence and presents unique clinical and operative challenges. Investigation for additional congenital abnormalities is appropriate, and although two-stage operative correction is considered the best treatment, long-term outcomes are uncertain
