Medline Citation Abstract Seventy-one parents and 40 siblings of 41 index patients with bilateral renal agenesis, bilateral severe dysgenesis, or agenesis of one kidney and dysgenesis of the other were evaluated by gray-scale ultrasonography for genitourinary malformations. Nine per cent (10 of 111) had asymptomatic renal malformations, most often unilateral renal agenesis (4.5 per centa frequency that was significantly higher than the frequency of 0.3 per cent among 682 adults [P less than 0.004]). We recommend ultrasonographic screening for parents and siblings of infants born with agenesis or dysgenesis of both kidneys or with agenesis of one kidney and dysgenesis of the other, since renal malformations may have medical implications even for asymptomatic patients.

Riñón único y embarazo. Resultados maternos y fetales Drs. Marisol Fernández B, Gerardo E. Fernández, Rafael Molina Vílchez Departamento de Obstetricia y Ginecología, Hospital Chiquinquirá, Maracaibo RESUMEN Objetivo : Investigar los resultados materno-fetales en gestantes con riñón único. Método : Se analizaron 32 embarazos en 15 pacientes: ocho uninefrectomizadas y siete con agenesia renal unilateral, seis de estas últimas con malformaciones müllerianas asociadas. Se revisó la duración de la gestación, vía del parto, y complicaciones materno-fetales. Ambiente : Departamento de Obstetricia y Ginecología, Hospital Chiquinquirá. Maracaibo. Resultados : Como complicaciones maternas para el total de embarazos hubo: anemia (25%), infección urinaria (15,63%), hipertensión inducida por el embarazo (6,25%), hipertensión crónica (3,13%) y ruptura prematura de membranas (3,13%). El parto fue vaginal en 53,57% y cesárea en 46,43%. Las cesáreas correspondieron a pacientes con agenesia renal en 85,71%. Las indicaciones fueron obstétricas. Hubo 27 nacimientos viables (84,37%), cuatro abortos (12,5%) y un mortinato (3,13%). Al grupo con agenesia renal pertenecieron todos los neonatos pretérmino (7,41%) y dos tercios de los abortos. Conclusiones : La presencia de un riñón único, per se, no incrementa la morbimortalidad maternofetal. El incremento ocurre cuando la agenesia renal se asocia a anomalía mülleriana.

Cryptophthalmos Syndrome (Fraser Syndrome) With Cardiac Findings In a Saudi Newborn Ali Aqeel, MD; Saleh Al-Alaiyan, MD, FRCPC Fraser syndrome (cryptophthalmos syndrome) is a rare autosomal recessive disorder. The most consistent features are cryptophthalmos, a broad and depressed nasal bridge, malformed ears, syndactyly of fingers and toes, abnormal genitalia, craniofacial skeletal defects, renal agenesis, and laryngeal stenosis. These anomalies were first documented by Fraser in 1962. We report the case of a full-term newborn who had multiple abnormalities consistent with cryptophthalmos syndrome. In addition, the newborn had a total anomalous pulmonary venous return (TAPVR), which is a new finding in patients with this syndrome. To the best of our knowledge, this is the first report of Fraser syndrome with cardiac lesion (TAPVR) in a Saudi infant. Case Report A 29-year-old Saudi woman, gravida 7 para 4, had a history of two abortions and three healthy children. She also had a history of a spontaneous vaginal delivery of a male infant with multiple malformations, including complete cryptophthalmos in both eyes, small malformed ears, syndactyly of all fingers, and cleft lip. The infant died 30 minutes after birth in a peripheral hospital, and thus, details were not available. The parents of this infant were second-degree cousins, and his cousin on the paternal side died immediately after birth with similar features. Ultrasound examination of the mother at 28 weeks' gestation demonstrated fetal ascites and unidentified urinary bladder and absent kidneys. At 33 weeks' gestation, ultrasound showed ascites, small left kidney, absent right kidney, thick-walled bladder, oligohydramnios, and increased echogenicity of the right lung. Fetal echocardiogram showed evidence of TAPVR and pericardial effusion. Screening for toxoplasmosis, rubella, syphilis, herpes simplex and cytomegalovirus was negative. Chromosomal study revealed normal male karyotype (46,XY). Pregnancy was induced at 39 weeks and the mother gave birth to a dysmorphic infant who

CME article 8 Dr. Rahul Sachdev, New Delhi Introduction Cysts of the seminal vesicles usually become apparent in the second to third decade during the period of greatest sexual or reproductive activity. Seminal vesicle cysts less than 5 cm may remain asymptomatic and are usually discovered incidentally as a palpable abdominal mass or on digital rectal examination as a palpable fluctuant mass arising from the superior aspect of the prostate gland. Clinical Features These cysts also may present with symptoms related to bladder irritation and obstruction. Commonly reported symptoms include abdominal, perineal, and pelvic pain; ejaculatory pain; dysuria; frequency; hematuria; urinary tract infections; and symptoms of epididymitis and prostatitis. Other reported symptoms include infertility, hemospermia, and, rarely, enuresis. Cysts of the seminal vesicles greater than 12 cm have been termed "giant" cysts and often are present with symptoms of

FitzPatrick Lab Bilateral Renal Agenesis Bilateral renal agenesis (BRA) or complete absence of the kidneys is a common lethal malformation occurring in 1 in 5000 births. It is twice as common in males as females. BRA appears to have a predominantly genetic aetiology and many cases represent the most severe manifestation of an autosomal dominant condition with incomplete penetrance and variable expressivity. We are assembling a panel of DNA samples from 50 Scottish infants who died as a result of BRA. These samples will be used to screen for mutations in candidate genes that will be chosen using strict criteria. Identification of the underlying genetic defects in these families would considerably help genetic counselling.
