Assisted reproductive technologies after conservative management of borderline or invasive ovarian tumours

OBJECTIVE: Ovulation induction, the usual resort of Assisted Reproductive Technologies (ART), has been suspected of carrying a responsibility in the genesis of ovarian tumours. For patients with a borderline or invasive ovarian tumour, treated by conservative surgery and desiring to become pregnant, the problem is thus of a possible resort to the Assisted Reproductive Technologies. PATIENTS AND METHODS: This is a multicenter, national and retrospective study. 40 operated patients between January 1971 and January 2001 have been included. 27 patients (67.5%) had a borderline tumour, 10 (25%) a non-epithelial tumour (germinal or stromal) and 3 (7.5%) an epithelial invasive carcinoma. All these patients have benefited from a conservative surgical management of fertility. The Assisted Reproductive Technologies were simple stimulation for 5 women and IVF for the 35 others. The effectiveness and the risks of Assisted Reproductive Technologies have been estimated respectively by the number of pregnancies obtained and the recurrence rates. RESULTS: With a global follow-up of 372 months (January 1971: date of the primary surgical procedure--June 2002: closing of the study), 17 patients have obtained 17 pregnancies with the Assisted Reproductive Technologies, rate of 42.5% (17/40): 1 spontaneous abortion, 16 delivery with 23 children (triple pregnancies and 3 twin pregnancies). 3 patients treated for a borderline tumour have had a recurrence after induction of ovulation. Among the 40 patients, no one presented an evolved disease at the last news. The patients who had a recurrence had a delay to begin the Assisted Reproductive Technologies significantly lower than the patients who had no recurrence. DISCUSSION AND CONCLUSION: The assisted reproductive technologies for patients who had been treated for a borderline or invasive ovarian tumour, and who were infertile in spite of conservative management, have allowed 42.5% of these women to obtain a pregnancy and does not seem to increase significantly the risk of recurrence.     

Effect of tumour and chemoradiotherapy on oesophageal motility

Background The contribution of dysmotility to dysphagia in oesophageal cancer is unclear. Aim To examine oesophageal motility in patients with oesophageal carcinoma and to assess the effect of chemoradiotherapy on motility. Methods Stationary manometry and 24-hour pH-metry were performed in 12 patients with oesophageal carcinoma and one week following completion of chemoradiotherapy using 5-fluorouracil (5-FU), cisplatin and 40Gy radiotherapy. Results All patients had abnormal motility prior to treatment. Peristalsis was impaired in 11 patients with a mean (SD) of 25% (9) of waves normally propagated. Eight patients had 20% or more simultaneous waves. Following chemoradiotherapy, the percentage of waves normally propagated increased from 25% (9) to 52% (10) (p < 0.03) and normal peristalsis was restored in four patients. The percentage of simultaneous waves decreased from 38% (11) to 21.6% (10) (p=0.129) while the percentage of dropped or increased waves decreased from 20% (11) to 8.3% (4) (p=0.264). Conclusions Oesophageal motility is disturbed in oesophageal cancer. Dysphagia in oesophageal cancer may be partly explained by oesophageal dysmotility. This is improved by chemotherapy.     

Pulmonary cystic hydatid disease in Ireland

Background Hydatid disease is rare in Ireland and its incidence and prevalence are unknown. Most cases are diagnosed by a combination of clinical findings, morphological features on imaging and by serological testing. Aims We describe an Irish case of pulmonary hydatid disease detected at bronchoscopy by bronchoalveolar lavage, and discuss the diagnosis and treatment of the disorder.

Endorectal sonography in gynecology: usefulness and diagnostic accuracy

OBJECTIVE: The aim of this study was to assess feasibility and diagnostic accuracy of endorectal sonography (ERS) in comparison with transabdominal sonography (TAS) in women with a contraindication to endovaginal sonography (EVS). PATIENTS AND METHODS: ERS was proposed to 32 patients in the immediate continuation of TAS. It was performed either with a specific probe or with a vaginal probe. The protocol included a complete evaluation of pelvic structures observed with both sonographic techniques. RESULTS: After counselling and assent, 29 of the 32 patients (90%) accepted ERS. The examination was regarded as complete in 28 cases. ERS confirmed the absence of pelvic anomaly in the 12 cases of normal TAS. ERS modified diagnosis in 5 of the 8 cases of anechoic ovarian cysts seen in TAS. In 4 cases, PCOs not seen in TAS were identified. Two partially sub-mucous myomas not recognized by TAS were diagnosed by ERS. Sensibility, specificity, positive predictive value (PPV) and negative predictive value (NPV) of TAS and ERS were 38,4 and 87,5%, 41,6 and 100%, 50 and 100%, 40 and 85,7% respectively. DISCUSSION AND CONCLUSION: These findings suggest ERS is an effective diagnostic tool in pelvic exploration when EVS cannot be performed. It should be widely proposed after information and assent.     

Recovery of anterograde amnesia in a case of craniopharyngioma

BACKGROUND: Studies of the amnesic syndrome have indicated that telencephalic and diencephalic structures are critical components of the memory system. The exact role of the mammillary bodies (MBs) in human memory remains elusive, since few cases of selective MB damage have been reported. OBJECTIVE: To study a case of severe anterograde amnesia due to a third-ventricle craniopharyngioma with severe MB compression. DESIGN: Case report. SETTING: Neurosurgery clinic of an academic hospital. PATIENT: A 53-year old woman who developed severe anterograde amnesia due to a third-ventricle craniopharyngioma strongly compressing the MBs and, to a lesser extent, the right hippocampus. INTERVENTIONS: Surgical excision of the tumor and neuropsychological testing and positron emission tomography during an associative memory test before and 2 months after tumor removal. A postsurgical magnetic resonance image did not show evidence of damage to the hypothalamus, thalamus, hippocampus, or MBs. MAIN OUTCOME MEASURES: Changes in brain imaging data and results of neuropsychological testing. RESULTS: After tumor removal, the patient showed a complete recovery of memory functions. Performance on the associative memory test was at chance level before surgery and dramatically improved postoperatively. Results of the preoperative positron emission tomographic study showed no activity in memory-related structures. In contrast, a significant blood flow increase occurred in the anterior thalamic nuclei postoperatively. CONCLUSIONS: These behavioral and brain imaging data stress the importance of the MBs in this patient's amnesia. Our data further suggest that the clinical prognosis of decompressing the mammillothalamic tract is excellent, even in cases of massive compression.     

Early prophylactic inhaled beclomethasone in infants less than 1250 g for the prevention of chronic lung disease

OBJECTIVE:

Inflammation plays an important role in the development of chronic lung disease (CLD), which has become a major cause of morbidity in surviving infants less than 1250 g at birth. The authors hypothesized that the progression of this inflammation and, therefore, the establishment of CLD would be decreased with the use of early prophylactic inhaled corticosteroids. Short, and long term respiratory and neurodevelopmental outcomes were also examined.

DESIGN:

A double-blind, randomized placebo controlled trial.

SETTING:

Level-III neonatal intensive care unit.

POPULATION STUDIED:

Sixty infants less than 1250 g at birth, diagnosed with respiratory distress syndrome and requiring ventilatory support at 72 h of age were enrolled in the study.

INTERVENTION:

Infants enrolled received either placebo or beclomethasone diproprionate by a metered dose inhaler, which was used in-line with the ventilator circuit while the infant was ventilated and then via a spacer until 28 days of age.

RESULTS:

Thirty infants were given beclomethasone and 30 were given placebo. There were two deaths in each group. Among the surviving infants, the frequency of moderate-to-severe CLD was 17% in each study group. Mean time to extubation was not different for beclomethasone compared with placebo at 16.4 and 12.5 days (P=0.12), respectively. The requirement for intravenous corticosteroids was lower in the beclomethasone-treated group (RR 0.67, 95% CI 0.43 to 1.04), although this difference was not statistically significant. The incidence of growth failure, infection and intraventricular hemmorhage did not differ between the two groups. Long term outcomes were not different with respect to the incidence of respiratory re-admissions, cerebral palsy, developmental delay, blindness or deafness.

CONCLUSIONS:

Early treatment with inhaled beclomethasone diproprionate did not reduce the incidence of CLD or decrease the duration of mechanical ventilation. The decrease in intravenous corticosteroid use was not statistically significant. Long term outcome was not affected.
