1/532. prenatal diagnosis of thyroid hormone resistance.A 29-yr-old woman with pituitary resistance to thyroid hormones (PRTH) was found to harbor a novel point mutation (T337A) on exon 9 of the thyroid hormone receptor beta (TRbeta) gene. She presented with symptoms and signs of hyperthyroidism and was successfully treated with 3,5,3'-triiodothyroacetic acid (TRIAC) until the onset of pregnancy. This therapy was then discontinued in order to prevent TRIAC, a compound that crosses the placental barrier, from exerting adverse effects on normal fetal development. However, as the patient showed a recurrence of thyrotoxic features after TRIAC withdrawal, we sought to verify, by means of genetic analysis and hormone measurements, whether the fetus was also affected by RTH, in order to rapidly reinstitute TRIAC therapy, which could potentially be beneficial to both the mother and fetus. At 17 weeks gestation, fetal dna was extracted from chorionic villi and was used as a template for PCR and restriction analysis together with direct sequencing of the TRbeta gene. The results indicated that the fetus was also heterozygous for the T337A mutation. Accordingly, TRIAC treatment at a dose of 2.1 mg/day was restarted at 20 weeks gestation. The mother rapidly became euthyroid, and the fetus grew normally up to 24 weeks gestation. At 29 weeks gestation mild growth retardation and fetal goiter were observed, prompting cordocentesis. Circulating fetal TSH was very high (287 mU/L) with a markedly reduced TSH bioactivity (B/I: 1.1 /- 0.4 vs 12.7 /- 1.2), while fetal FT4 concentrations were normal (8.7 pmol/L; normal values in age-matched fetuses: 5-22 pmol/L). Fetal FT3 levels were raised (7.1 pmol/L; normal values in age-matched fetuses: <4 pmol/L), as a consequence of 100% cross-reactivity of TRIAC in the FT3 assay method. To reduce the extremely high circulating TSH levels and fetal goiter, the dose of TRIAC was increased to 3.5 mg/day. To monitor the possible intrauterine hypothyroidism, another cordocentesis was performed at 33 weeks gestation, showing that TSH levels were reduced by 50% (from 287 to 144 mU/L). Furthermore, a simultaneous ultrasound examination revealed a clear reduction in fetal goiter. After this latter cordocentesis, acute complications occured, prompting delivery by cesarean section. The female neonate was critically ill, with multiple-organ failure and respiratory distress syndrome. In addition, a small goiter and biochemical features ofhypothyroidism were noted transiently and probably related to the prematurity of the infant. At present, the baby is clinically euthyroid, without goiter, and only exhibits biochemical features of RTH. In summary, although further fetal studies in cases of RTH are necessary to determine whether elevated TSH levels with a markedly reduced bioactivity are a common finding, our data suggest transient biochemical hypothyroidism in RTH during fetal development. Furthermore, we advocate prenatal diagnosis of RTH and adequate treatment of the disease in case of maternal hyperthyroidism, to avoid fetal thyrotrope hyperplasia, reduce fetal goiter, and maintain maternal euthyroidism during pregnancy.- - - - - - - - - - ranking = 1keywords = duct (Clic here for more details about this article) |
2/532. hydronephrosis in pregnancy: simultaneous depiction of fetal and maternal hydronephrosis by magnetic resonance urography.Magnetic resonance urographic (MRU) techniques possess image quality and diagnostic capability that are improving with increasingly sophisticated imaging sequences and shorter scanning times. We describe the application of a fast breath-hold MR sequence (HASTE) in the assessment of ureteric obstruction in pregnancy. In the patient presented, HASTE MRU was successful in depicting ureteral anatomy and demonstrated dilation of both ureters below the level of the pelvic brim. This observation suggested distal ureteral obstruction rather than simple hydronephrosis of pregnancy. As a result, bilateral nephrostomies were performed and neonatal prematurity was avoided. Interestingly, in this patient, HASTE MR imaging also showed evidence of concurrent fetal hydronephrosis.- - - - - - - - - - ranking = 76.959592782178keywords = obstruction (Clic here for more details about this article) |
3/532. Four cases with chronic intestinal pseudo-obstruction due to hollow visceral myopathy.BACKGROUND/AIMS: Chronic intestinal pseudo-obstruction is a rare clinical syndrome characterized by symptoms and signs of intestinal obstruction without any organic lesion obstructing the intestine. Visceral myopathy is one of the etiological causes and full thickness intestinal biopsy is essential for reaching a diagnosis. In this article we describe 4 cases of hollow visceral myopathy; our aim is to stress the importance of full thickness biopsy. METHODOLOGY: Four cases of hollow visceral myopathy are studied herein. All the patients had recurrent abdominal pain and constipation. The onset of symptoms was early in life or in the second to third decade. A diagnosis was established in all cases by full thickness intestinal biopsy obtained during laparotomy. Associated disorders were noted in 2 cases. One patient had Axenfelt syndrome, non-descended testicles and primary hypogonadism, and another had a diagnosis of Kleinfelter syndrome. RESULTS: All of the 4 cases were diagnosed to be suffering from hollow visceral myopathy by full thickness intestinal biopsy and 2 had additional disorders as well. CONCLUSIONS: patients with chronic intestinal pseudo-obstruction should be carefully evaluated as to whether there is an associated disorder and the diagnosis may be delayed unless full thickness intestinal biopsy is obtained.- - - - - - - - - - ranking = 269.35857473762keywords = obstruction (Clic here for more details about this article) |
4/532. Treating allergic rhinitis in pregnancy. safety considerations.Allergic rhinitis affects approximately one-third of women of childbearing age. As a result, symptoms ranging from sneezing and itching to severe nasal obstruction may require pharmacotherapy. However, product labels state that medications for allergic rhinitis should be avoided during pregnancy due to lack of fetal safety data, even though the majority of the agents have human data which refute these notions. We present a systematic and critical review of the medical literature on the use of pharmacotherapy for the management of allergic rhinitis during pregnancy. Electronic databases and other literature sources were searched to identify observational controlled studies focusing on the rate of fetal malformations in pregnant women exposed to agents used to treat allergic rhinitis and related diseases compared with controls. immunotherapy and intranasal sodium cromoglycate (cromolyn) and beclo-methasone would be considered as first-line therapy, both because of their lack of association with congenital abnormalities and their superior efficacy to other agents. First-generation (e.g. chlorpheniramine) and second-generation (e.g. cetirizine) antihistamines have not been incriminated as human teratogens. However, first-generation antihistamines are favoured over their second generation counterparts based on their longevity, leading to more conclusive evidence of safety. There are no controlled trials with loratadine and fexofenadine in human pregnancy. Oral, intranasal and ophthalmic decongestants (e.g. pseudoephedrine, phenylephrine and oxymetazoline, respectively) should be considered as second-line therapy, although further studies are needed to clarify their fetal safety. No human reproductive studies have been reported with the ophthalmic antihistamines ketorolac and levocabastine, although preliminary data reported suggest no association between pheniramine and congenital malformations. There are no documented epidemiological studies with intranasal corticosteroids (e.g. budesonide, fluticasone propionate, mometasone) during pregnancy; however, inhaled corticosteroids (e.g. beclomethasone) have not been incriminated as teratogens and are commonly used by pregnant women who have asthma. In summary, women with allergic rhinitis during pregnancy can be treated with a number of pharmacological agents without concern of untoward effects on their unborn child. Although the choice of agents in part should be based on evidence of fetal safety, issue of efficacy needs to be addressed in order to optimally manage this condition.- - - - - - - - - - ranking = 40.479796391089keywords = obstruction, duct (Clic here for more details about this article) |
5/532. Supine hypotensive syndrome caused by intra-abdominal mass: a case report.An obese woman who presented with 3 separate intra-abdominal masses developed a supine hypotensive syndrome following induction of general anesthesia. The hypotension was corrected by positioning the patient in a left lateral tilt and by releasing intra-abdominal pressure. Following decompression of the vena cava, arterial and central venous pressure rose and remained at a high level. urine output was poor until IV furosemide was administered.- - - - - - - - - - ranking = 1keywords = duct (Clic here for more details about this article) |
6/532. Ultrasonic features of Gartner's duct cyst.Gartner's duct cysts will usually be incidental findings during pelvic sonography. Of developmental origin, they may present anywhere along the lateral aspect of the female genital tract. When the cysts are of parovarian origin, they will mimic other fluid-filled adnexal masses, and no specific diagnosis can be made. When alongside the vagina or cervix, however, their ultrasonographic appearance is probably characteristic.- - - - - - - - - - ranking = 5keywords = duct (Clic here for more details about this article) |
7/532. Ruptured tuboovarian abscess in late pregnancy. A case report.BACKGROUND: Tuboovarian abscess is an unusual obstetric complication that causes maternal and fetal morbidity and mortality. CASE: A woman, G1, P0, with a 32-week pregnancy presented with abdominal pain. physical examination on admission revealed fever and unremarkable abdominal signs. Eleven hours after admission, signs of peritonitis became prominent, necessitating emergency laparotomy. Surgical findings included an 8-cm, right, ruptured tuboovarian abscess with massive purulent contamination of the abdominal cavity. Cesarean hysterectomy with bilateral salpingo-oophorectomy was performed. Neither the newborn nor the mother had postoperative complications. CONCLUSION: Since there are discrepancies in the incidences of tuboovarian abscess in pregnant and nonpregnant groups, the pathogenesis of tuboovarian abscess may be different in the two populations. In pregnancy, diagnosis and management are also more difficult than in the nonpregnant state. Clinical data may not reveal the diagnosis until surgery is mandatory. Because most pregnant women with tuboovarian abscesses are young, conservative surgery should be attempted if the pathology is limited to only one side of the adnexa and further reproduction is desired.- - - - - - - - - - ranking = 1keywords = duct (Clic here for more details about this article) |
8/532. Multiple pregnancies in women after renal transplantation. Case report that rises a management dilemma.OBJECTIVES: To report the pregnancy outcome in women with multiple pregnancies after renal transplantation. MATERIALS AND methods: We report two cases of multiple pregnancies (triplets and twins) in renal allograft recipients and evaluate the pregnancy courses and maternal and fetal outcome of these patients. RESULTS: After fetal reduction from triplet to twin pregnancy the first patient delivered healthy twin babies at 36 weeks gestation. Six months after delivery the woman is well with no signs of renal function impairment. Although the second patient did not meet the optimal criteria for consideration of pregnancy in renal transplant recipients, she delivered normal twin babies at 33 weeks' gestation. Maternal complications during pregnancy included preeclampsia, mild deterioration of renal function tests, and secondary complications due to drug therapy that was resolved after delivery. No graft rejection episodes were noted in either case during pregnancy. CONCLUSIONS: Multifetal gestation in renal allograft recipients represents a high-risk pregnancy that should be managed at a tertiary care institution. The overall outcome in properly consulted patients can be considered favorable. Based on our limited experience with two cases, we suggest reduction of triplets to a twin pregnancy which is consistent with the current literature data.- - - - - - - - - - ranking = 2keywords = duct (Clic here for more details about this article) |
9/532. Severe alpha1-antitrypsin deficiency and pregnancy.This case study describes a successful pregnancy in a 27-yr-old patient with severe emphysema, secondary to alpha1-antitrypsin deficiency, genotype PiZZ. Despite significant respiratory compromise, more severe than previously reported, no complications ensued. Maternal pulmonary function did not deteriorate significantly until the 32nd week of pregnancy, with an elective Caesarean section being performed during the 37th week. This experience suggests that even severe maternal airflow obstruction is, in itself, not an absolute contra-indication to pregnancy. Pre-pregnancy multidisciplinary counselling is likely to be helpful in these patients, including frank discussion on the risks of pregnancy, the prospects of successful completion and the mother's future prognosis in relation to caring for the child.- - - - - - - - - - ranking = 38.479796391089keywords = obstruction (Clic here for more details about this article) |
10/532. Unilateral gestational macromastia--an unusual presentation of a rare disorder.Macromastia (mammary gigantism) is an uncommon clinical entity. Macromastia occurring during pregnancy (gestational macromastia) is rare. A case of unilateral gestational macromastia is reported which required reduction mammoplasty. We documented hyperprolactinaemia in the patient. This case report is particularly interesting because, to our knowledge, no such case has previously been reported.- - - - - - - - - - ranking = 1keywords = duct (Clic here for more details about this article) |
