Twin pregnancy with complete hydatidiform mole and coexisting fetus following ovulation induction with a non-prescribed clomiphene citrate regimen: a case report

<p>Abstract</p> <p>Introduction</p> <p>Twin pregnancy with complete hydatidiform mole represents a very rare obstetric problem. Management of such cases is always problematic because the possibility of fetal survival should always be weighed against the risk of complications of molar pregnancy.</p> <p>Case presentation</p> <p>A 34-year-old Caucasian woman presented to our center with mild vaginal bleeding. Our patient was 16 weeks pregnant after a seven-year period of primary infertility. She became pregnant following a non-prescribed regimen of clomiphene citrate extending from the second day to the 13th day of her last cycle. A transabdominal ultrasound examination revealed a twin pregnancy with complete hydatidiform mole and a coexisting fetus. Serum β human chorionic gonadotropin was falsely low as identified by serial dilution of the sample (the 'hook effect'). Our patient refused termination of pregnancy and she was hospitalized for strict observation and follow-up. Unfortunately, she developed an attack of severe vaginal bleeding and a hysterotomy was performed. The fetus died shortly after birth.</p> <p>Conclusions</p> <p>Twin pregnancy with complete hydatidiform mole represents a matter of controversy. We suggest that conservation should always be considered whenever tertiary care services and strict observation are available.</p

E.S.R. STUDY DURING THE ELECTROCHEMICAL N-TYPE DOPING OF (CH)x

Nous présentons et discutons les résultats préliminaires d'une étude par RPE du dopage avec Li+ par voie électrochimique de films de cis (CH)x. Pour les taux de dopage faibles (< 10-3 molaire), on observe une diminution progressive du nombre d'électrons non appariés alors que la largeur de raie du signal RPE ne change pas. Nous interprétons ces résultats en termes de dopage sélectif des parties trans du polymère.We present and discuss some preliminary results concerning the EPR study during the electrochemical Li+ doping of cis rich (CH)x films. With low doping levels (< 10-3 molar) we observe a continuous decrease of the unpaired electrons number While the EPR linewidth does not change. These results are interpreted in term of preferential doping of the trans parts of the polymer

(CH)x AS AN ELECTRODE MATERIAL : SOME PROPERTIES DURING THE ELECTROCHEMICAL PROCESS

Nous avons étudié le comportement d'électrodes de (CH)x dopé p dans des batteries rechargeables (CH)x/1M LiClO4 dans CP/Li. Nous avons mesuré la tension sous courant constant, le rendement faradique en fonction de l'état de charge et estimé l'importance des réactions parasites. Par ailleurs, nous avons déduit le coefficient de diffusion des ions ClO4- dans le matériau solide et évalué le nombre limite de cycles charge-décharge d'amplitude 0,07 electrons par unité CH.We have studied the behaviour of p-type doped (CH)x electrodes in rechargeable batteries (CH)x/1M LiClO4 in PC/Li. We have measured the cell voltage under constant current, the coulombic efficiency versus the charge state and estimated the importance of side reactions. Furthermore we have deduced the ClO4- diffusion coefficient in the solid material and evaluated the limit number of charge-discharge cycles with an amplitude of 0.07 electrons per CH unit
