Abstract
BACKGROUND DLEUs are a major cause of morbidity. Appropriate treatment is essential, and newer methods to achieve ulcer healing have been described, including application of PG. OBJECTIVE This study evaluated the effectiveness and safety of homologous PG in patients with chronic noninfected DLEU refractory to standard treatment as well as possible correlations between patient comorbidities and response to treatment. MATERIALS AND METHODS Data from patients with chronic refractory DLEU managed with homologous PG between January 2014 and October 2022 were evaluated (comorbidities, wound characteristics, number and time of treatment, outcome). Outcome was classified as complete response (complete ulcer healing with reepithelialization), partial response (≥50% reduction in area and/or improvement of pain), or absence of response. The chi-square test was used to compare groups, with alpha level set at less than .05. RESULTS A total of 81 patients (63 male, 18 female; median age, 65 years; median HbA1c, 7.6%; median ulcer area, 2.9 cm2) were proposed for PG application. A total of 62 patients had 3 or more comorbidities. Outcome was evaluated in 69 patients, with response observed in 49% (complete, 32%; partial, 17%). Worse outcomes occurred in patients with polyneuropathy (chi-square statistic: 4.183; P = .041). CONCLUSION Homologous PG is a safe and possibly effective therapeutic alternative for DLEU that is unresponsive to standard therapies.

Abstract
INTRODUCTION X-linked myotubular myopathy is a rare centronuclear myopathy that affects approximately 1 in 50,000 male newborns caused by pathogenic variants in the myotubularin 1 gene (MTM1). The clinical severity varies, however the need for ventilatory support occurs almost invariably. CASE REPORT We report the case of a 4-year-old boy presenting mild muscle hypotonia at 12 months-old, expressive language disorder, global developmental delay, and a sensory processing disorder. Clinical exome sequencing identified the hemizygous variant c.722G>A p.(Arg241His) in exon 9 of the myotubularin 1 gene (NM_000252.2). The mother is a heterozygous carrier of the same variant. A diagnosis of a mild form of maternal inherited X-linked myotubular myopathy was established. The child presented significant improvement with speech, occupational, and physical therapies, with no respiratory intercurrences or ventilator dependency. CONCLUSION The presentation of a mild form of this myotubular myopathy, being less commonly reported, added challenge to the diagnosis. The combination of mild hypotonia, feeding difficulties and expressive language disorder should raise suspicion of a neuromuscular disease. There is a lack of verified motor or developmental scores specific to this myopathy to further determine prognosis and need of other therapies. While currently the severity myotubular myopathy is classified according to ventilator dependency, this may be insufficient and unapplicable to milder cases. There is an evident need for a grading system for mild and moderate cases assessing muscle weakness and fatigue, daily life limitations, motor developmental delay, early phenotypical scores, or recurrent respiratory infections.

Abstract
INTRODUCTION PURA syndrome is a rare autosomal dominant condition caused by de novo pathogenic variants in PURA gene and characterized by a multisystemic phenotype that includes global neurodevelopmental delay, early hypotonia, absence of speech, feeding difficulties, hypersomnolence, epilepsy and movement disorders. CASE REPORT We report a 9-year-old girl with hypotonia and feeding difficulties with failure to thrive since the neonatal period. At the age of 3 years motor and intellectual delay were evident, she had a wide-based gait, no speech and an exaggerated acoustic startle response. She developed hand-mouthing stereotypies and epilepsy at 6 years old. The 24 hours continuous electroencephalogram monitoring revealed global slow activity and frequent epileptiform activity in left temporal and centrotemporal areas. The brain MRI revealed delayed myelination. At 6 years old the clinical exome sequencing identified a heterozygous pathogenic variant in the PURA gene, c.153delA p.(Leu54CysfsTer24). CONCLUSION PURA syndrome has clinical features similar to other neurological disorders but the association with some clinical features, not as common in other neurological entities, like never being able to speak but being able to follow simple orders and exaggerated acoustic startle response, should raise the suspicion of PURA syndrome and genetic analysis must be performed to confirm the diagnosis and provide early multidisciplinary intervention.

Abstract
AbstractEarly infantile epileptic encephalopathy-64 (EIEE 64), also called RHOBTB2-related developmental and epileptic encephalopathy (DEE), is caused by heterozygous pathogenic variants (EIEE 64; MIM#618004) in the Rho-related BTB domain-containing protein 2 (RHOBTB2) gene. To date, only 13 cases with RHOBTB2-related DEE have been reported. We add to the literature the 14th case of EIEE 64, identified by whole exome sequencing, caused by a heterozygous pathogenic variant in RHOBTB2 (c.1531C > T), p.Arg511Trp. This additional case supports the main features of RHOBTB2-related DEE: infantile-onset seizures, severe intellectual disability, impaired motor functions, postnatal microcephaly, recurrent status epilepticus, and hemiparesis after seizures.

Abstract
Background Rare pathogenic variants in either the ITGA2B or ITGB3 genes have been linked to autosomal dominant macrothrombocytopenia associated with abnormal platelet production and function, deserving the designation of Glanzmann Thrombasthenia-Like Syndrome (GTLS) or ITGA2B/ITGB3-related thrombocytopenia. Objectives To describe a series of patients with familial macrothrombocytopenia and decreased expression of αIIbβ3 integrin due to defects in the ITGA2B or ITGB3 genes. Methods We reviewed the clinical and laboratory records of 10 Portuguese families with GTLS (33 patients and 11 unaffected relatives), including the functional and genetic defects. Results Patients had absent to moderate bleeding, macrothrombocytopenia, low αIIbβ3 expression, impaired platelet aggregation/ATP release to physiological agonists and low expression of activation-induced binding sites on αIIbβ3 (PAC-1) and receptor-induced binding sites on its ligand (bound fibrinogen), upon stimulation with TRAP-6 and ADP. Evidence for constitutive αIIbβ3 activation, occurred in 2 out of 9 patients from 8 families studied, but also in 2 out of 12 healthy controls. We identified 7 missense variants: 3 in ITGA2B (5 families), and 4 in ITGB3 (5 families). Three variants (αIIb: p.Arg1026Trp and p.Arg1026Gln and β3: p.Asp749His) were previously reported. The remaining (αIIb: p.Gly1007Val and β3: p.Thr746Pro, p.His748Pro and p.Arg760Cys) are new, expanding the αIIbβ3 defects associated with GTLS. The integration of the clinical and laboratory data allowed the identification of two GTLS subgroups, with distinct disease severity. Conclusions Previously reported ITGA2B and ITGB3 variants related to thrombocytopenia were clustered in a confined region of the membrane-proximal cytoplasmic domains, the inner membrane clasp. For the first time, variants are reported at the outer membrane clasp, at the transmembrane domain of αIIb, and at the membrane distal cytoplasmic domains of β3. This is the largest single-center series of inherited macrothrombocytopenia associated with αIIbβ3 variants published to date.

Abstract
Abstract
Introduction Portugal currently has one of the most aging populations in Europe. Aging is usually associated with increased inactivity, decreased physical capacity and a higher incidence of disease, all of which leads to a reduction in functional changes and, consequently, loss of independence. Therefore, it is necessary to ensure that this population maintains a satisfactory level of physical and mental skills, emotional well-being and especially independence to perform day-to-day activities, and, to that end, measures are needed to promote health and allow a better quality of life.
Objectives To verify if the physical fitness components are determinant for the health status of the elderly.
Methodology A cross-sectional study was carried out on non-institutionalized elderly. For data collection, a questionnaire with sociodemographic data, the SF-12 questionnaire, to assess health status (physical and mental component), and the Senior Fitness Test (strength of lower and upper limbs, agility / balance, flexibility of the lower and upper limbs and cardiorespiratory fitness) to assess functional physical fitness were conducted.
Results The sample is composed of 439 individuals, aged between 65 and 95 years old, mostly women. The set of physical fitness components: cardiorespiratory fitness, agility / balance, body mass index, lower and upper limb strength, explained by 35% of the variation in physical component from SF-12. The cardiorespiratory fitness and upper limb strength predict 9% of mental health status.
Conclusion Some physical fitness components determine elderly health status, especially the physical dimension. Thus, for the elderly population the training of these components of the physical fitness is recommended in order to improve their health status.

Abstract
UNLABELLED In this observational study performed during 45 months we evaluated patients with chronic and recalcitrant diabetic ulcers who were treated with homologous platelet gel. METHODS platelet gels were obtained from homologous platelet concentrates that were aliquoted and freezed, being then activated with calcium gluconate and applied in the ulcer after cleaning and debridement. We evaluated patient's comorbidities, wound characteristics (size, tissue, inflammatory signs, pain), number and time of treatment as well as outcome (classified as complete epithelialization; partial improvement- 50% reduction in wound size or pain relief; no evolution). RESULTS Fifty-two patients (42 males, 10 females), with a median age of 65 years (range 43-85) were proposed for platelet gel. The following associated comorbidities were observed: hypertension (n = 41), dyslipidemia (n = 29), polyneuropathy (n = 30), peripheral arteriopathy (n = 32), retinopathy (n = 21), nephropathy (n = 15), cardiac ischemic disease (n = 14), obesity (n = 9). Thirty-eight patients presented with 3 or more associated comorbidities. The more frequent ulcer locations were sole of the foot (n = 13) and heel (n = 10). The median number of applications was 16, during 8.5 weeks. Nineteen patients (44%) achieved complete healing, 3 patients (7%) had a partial response and 21 (49%) had no progression. We did not observe a statistically significant relationship between patient age and response nor between number of comorbidities and response. We observed a more favorable evolution in patients with good compliance and good glycemic control. CONCLUSION Platelet gel is an effective therapeutic alternative, provided compliance and effective metabolic control are ensured.

Abstract
OBJECTIVE To evaluate whether the freeze-all strategy affects in-vitro fertilization (IVF) outcome in poor ovarian responders (POR) defined according to the Bologna criteria. METHOD This was a retrospective cohort study of patients undergoing IVF treatment between January 2012 and December 2016 at a single center. A total of 433 POR (as defined by the Bologna criteria) fulfilled criteria and were included in the study; of these, 277 patients underwent fresh embryo transfer (ET) and 156 followed the freeze-all policy. All patients underwent controlled ovarian stimulation (COS) following a gonadotropin-releasing hormone antagonist protocol, and cleavage-stage ET. Main outcome measure was ongoing pregnancy rate. Secondary outcomes included implantation and clinical pregnancy rates. The freeze-all strategy was implemented when the progesterone serum level was > 1.5 ng/mL or the endometrium was < 7 mm on the trigger day, or as per patient preference. Patients with previous failed fresh ET also underwent fresh ET or freeze-all strategy considering the indications mentioned above. RESULTS Mean maternal age in the freeze-all group was 39.5 ± 3.6 years and in the fresh ET group was 39.7 ± 3.8 years (P = 0.54). Mean number of embryos transferred (nET) was 1.53 ± 0.6 and 1.60 ± 0.6 (P = 0.12) in the freeze-all and fresh ET groups, respectively. Ongoing pregnancy rate did not differ significantly between the freeze-all and fresh ET groups (9.6% vs 10.1%, respectively; relative risk (RR), 0.95; 95% CI, 0.52-1.73), nor did the clinical pregnancy rate (14.1% vs 13.7%, respectively; RR, 1.03; 95% CI, 0.63-1.67). Implantation rate was 9.6% and 9.8% (P = 0.82) in the freeze-all and fresh ET groups, respectively. Logistic regression analysis (including maternal age, antral follicle count, number of retrieved and mature oocytes, nET, and fresh ET vs freeze-all strategy) indicated that maternal age (P < 0.001) and nET (P = 0.039) were the only independent variables associated with ongoing pregnancy rate. CONCLUSIONS The freeze-all strategy, compared with fresh ET, had no impact on IVF outcomes in POR patients as defined according to the Bologna criteria. Multicenter studies including large numbers of patients should be carried out to confirm the results of this study and reach conclusions about the potential benefits of the freeze-all policy for poor responders.

Abstract
Intracytoplasmic sperm injection (ICSI) may be performed with testicular frozen-thawed spermatozoa in patients with nonobstructive azoospermia (NOA). Sperm retrieval can be performed in advance of oocyte aspiration, as it may avoid the possibility of no recovery of spermatozoa on the day of oocyte pickup. There are few studies available in the literature concerning the use of frozen-thawed spermatozoa obtained from testicular sperm aspiration (TESA). To evaluate the effects and the outcomes of ICSI with frozen-thawed spermatozoa obtained by TESA, we performed a retrospective analysis of 43 ICSI cycles using frozen-thawed TESA. We obtained acceptable results with a fertilisation rate of 67.9%, an implantation rate (IR) of 17.1%, and clinical and ongoing pregnancy rates of 41.9% and 37.2% respectively. The results of this study suggest that performing ICSI using cryopreserved frozen-thawed testicular spermatozoa with TESA as a first option is a viable, safe, economic and effective method for patients with NOA.

Abstract
This work was aimed at studying the behaviour of 222Rn in an experimental underground copper mine in Brazil with a single entrance. The 222Rn concentrations, meaured by using a dynamic radon measuring technique. varied between 30.5 Bq.m(-3), during ventilated conditions applied to the mine galleries, and 19.4 x 10(3) Bq.(-3) for non-ventilated conditions and when operational mining activities were conducted inside. High radon concentration surges were observed after blasting and drilling activities. In the cases of inadequate ventilation, it was estimated that workers could be subjected to exposures as high as 10 microSv.h(-1), only due to 222Rn and its short-lived progeny. The results show the importance of real-time measurements to evaluate radon dynamics during mining operations.

Abstract
SUMMARY We describe a rare case of multiple arteriovenous fistulae of the spinal cord (SCAVF) in the same myelomer in a five-year-old boy. This case report consists of a trifocal SCAVF at the Th12 myelomeric level without communication between the three different fistulae. Two AVF were located posteriorly, bilateraly, in the spinal cord, fed by left and right posterior radiculopial arteries and one anteriorly in the anterior spinal axis. The venous drainage was independent for each lesion. The patient presents associated lesions characterized by cutaneous stain and inferior limb asymmetry. A metameric distribution is the explanation for the multiplicity of these lesions in a syndromic association related to Cobb syndrome. The patient was treated by transarterial embolization using glue with occlusion of the three different fistulae. The patient achieved a good improvement in neurological status.

Abstract
A novel serine proteinase inhibitor, DgTI, was purified from Dioclea glabra seeds by acetone precipitation, and ion-exchange and reverse phase chromatography. The inhibitor belongs to the Bowman-Birk family, and its primary sequence, determined by Edman degradation and mass spectrometry, of 67 amino acids is: SSGPCCDRCRCTKSEPPQCQCQDVRLNSCHSACEACVCSHSMPGLCSCLDITHFCHEPCKSSGDDED++ +. Although two reactive sites were determined by susceptibility to trypsin (Lys(13) and His(40)), the inhibitory function was assigned only to the first site. The inhibitor forms a 1:1 complex with trypsin, and Ki is 0.5 x 10(-9) M. Elastase, chymotrypsin, kallikreins, factor Xa, thrombin, and plasmin were not inhibited. By its properties, DgTI is a Bowman-Birk inhibitor with structural and inhibitory properties between the class of Bowman-Birk type I (with a fully active second reactive site), and Bowman-Birk type II (devoid of second reactive site).

Abstract
One of the most important and unsolved problems in in-vitro fertilization is to decide which embryos are more suitable to implant and therefore should be transferred. We analysed the in-vitro development of isolated biopsied blastomeres and compared it to the development of the original embryo, in order to find a relationship that could show the embryo's potential future development and so increase implantation rates. A total of 66 normally fertilized human embryos were biopsied at the 6- to 10-cell stages. At day 6, blastomeres were counted by nuclear labelling. A total of 33 embryos (50%) reached the blastocyst stage. Of the isolated blastomeres, 63% divided and 53% cavitated over 3 days in culture. Of the blastomeres taken from embryos that developed to the blastocyst stage, 88% divided, 79% cavitated, 76% divided and cavitated and 9% neither divided nor cavitated. In those from arrested embryos, 39% divided (P < 0.001), 21% cavitated (P < 0.001), 15% divided and cavitated (P < 0.001) and 55% neither divided nor cavitated (P < 0.001). Blastomeres biopsied from embryos that reached the blastocyst stage showed a significantly higher proportion of division and cavitation than those originated from arrested embryos. Culture of the isolated blastomeres can demonstrate those embryos more likely to develop to the blastocyst stage and that are probably more suitable to implant. Cryopreserving biopsed embryos and culturing blastomeres would increase implantation rates. Embryos can then be selected according to the blastomere development and thawed for transfer in a future cycle.

Abstract
PURPOSE To evaluate the antihypertensive efficacy and safety of cilazapril compared to nifedipine retard in mild to moderate hypertension. METHODS forty randomized out-patients with mild moderate hypertension, diastolic pressure (DP) between 95 and 115 mmHg, with placebo for 15 days were randomized and allocated for treatment, double-blind, once daily with cilazapril 2.5 mg (n = 20) or nifedipine retard 20 mg (20 = n) for four weeks. The non-responders (DP > 90mmHg) had the dosage increased twice, b.i.d., while responders were maintained up to 10 weeks. Clinical visits were performed before, at baseline and every two weeks and the laboratory test was performed after placebo run-in, 4th and 10th weeks of treatment. RESULTS The blood pressure (BP) were similar between groups at the end of the placebo (cilazapril 151 +/- 14/103 +/- 5 - nifedipine 157 +/- 17/108 +/- 7mmHg, p > 0.05). DP decreased already at second weeks (cilazapril 95 +/- 9 - nifedipine 96 +/- 11mmHg, p < 0.05, compared to week 0) in both groups at the end of study with no difference inter groups. BP normalization was obtained in 58% of the patients with cilazapril and in 61% in the nifedipine group. Adverse biochemical effects were not observed in any group. Six (16%) patients of the cilazapril and 15 (39%) of nifedipine related collateral events, although no difference were observed between groups. CONCLUSION Cilazapril 2.5 to 25mg normalized BP in 58% of mild and moderate hypertension patients, and this efficacy was similar to sustained-release nifedipine 20 to 40mg. Cilazapril had no adverse effects on the biochemical parameters with low incidence of collateral effects.

Abstract
Two hundred and four patients who underwent renal transplantation were followed up as outpatients with a minimum of four years. They were divided into two socio-economic levels: group I - 104 patients who underwent transplantation in a private hospital and 120 patients (group II) with a lower socio-economic standard, treated in a public hospital. In both groups urinary infections and hepatitis were excluded. The incidence of infection in group I was 24% and in group II, 50% (p = 0.0002). There was no difference in relation to viral infection in either groups. However, bacterial infection and infection by opportunistic agents were significantly higher in group II (p = 0.0001 and p = 0.0282). The number of hospitalizations and the number of infections of patients were higher in group II. There was a tendency for an increase in mortality owing to infection in group II. There was no difference in the two groups as the parameters of: age, sex, type of donor, primary disease, number of rejections crises, level of serum creatinine and number of patients with ciclosporine. On the other hand, the dose of azathioprine and prednisone was mildly higher in those patients of group II. Low level of socio-economic conditions is a risk factor in renal transplant patients.

Abstract
PURPOSE To compare the antihypertensive and metabolic effects of captopril combined with hydrochlorothiazide (C+HCTZ) versus chlorthalidone (CT) in mild and moderate primary hypertensive patients. METHODS Fifty five patients, without treatment or treated with 15 days placebo were randomized for treatment with the combination of captopril 50mg and hydrochlorothiazide 25mg (n = 29) against chlorthalidone (n = 26). The clinical evaluation was done during placebo and monthly throughout three months, and the laboratory tests were done before and at the end of the study. RESULTS The blood pressure were similar between groups during placebo period (C + HCTZ: 161 +/- 25/102 +/- 6-CT: 155 +/- 18/101 +/- 6 mmHg); the diastolic blood pressure decreases significantly at first month already in the group C + HCTZ (89 +/- 8 mmHg) compared to group CT (94 +/- 8 mmHg, p < 0.05). The percentile diastolic and mean blood pressure dropped, in average, 12% in C + HCTZ group and in CT varied between 7 (1st and 2nd month) to 11% (3rd month). Without statistical difference, the blood pressure normalization was obtained in 69% of the patients with the association captopril and diuretic and in 50% of the patients in the chlorthalidone group. It was observed a significant reduction of potassium in patients treated with chlorthalidone (4.2 +/- 0.7 to 3.7 +/- 0.4 mEq/L, p < 0.01) that was not observed with the captopril and the thiazide associated. The last treatment also significantly reduced the cholesterol levels (219 +/- 39 mg/dl to 202 +/- 39 mg/dl, p < 0.04). CONCLUSION Our results indicate that captopril combined with low diuretic dose normalize the blood pressure in 69% mild to moderate primary hypertensive patients, and acts faster than chlorthalidone in this control. In addition has metabolic benefits reducing cholesterol levels with no alteration in potassium levels.

Abstract
Several lines of investigation suggest a direct modulatory role for gonadotrophin-releasing hormone (GnRH) on granulosa cell functions. Also, GnRH and its analogues (GnRHa) have been implicated in the resumption of meiosis, both in vivo and in vitro. Despite the presence of specific receptors for GnRH on human granulosa and luteal cells, very little is known about the possible effects of this hormone on the ovary. The use of GnRHa for long periods of time in patients undergoing in vitro fertilization (IVF) may influence granulosa cell function and/or oocyte maturation. We describe our clinical and experimental data in which we have searched for evidence of a direct action of GnRHa on the ovary. We have found that the retrieval of higher numbers of oocytes in women treated with GnRHa is correlated with oocytes of lower quality, manifested by a decreased fertilization and implantation rate. This impairment seems to be the consequence of oocyte immaturity, as ascertained by cytogenetic analysis of unfertilized oocytes in which an increase in diploidy, as well as prematurely condensed sperm chromosomes of the G1 phase, was observed in women with an excessive response to the stimulating drugs. Follicular atresia was not increased in women treated with GnRHa. Thus, there was no evidence for a direct effect of GnRHa on the human oocyte. Rather, the observations reflect the harmful effect of pushing follicles in early stages of development using this stimulation protocol. We have also searched for possible effects of GnRHa on granulosa-luteal cells obtained at ovum collection. In vitro culture of these cells has shown that the steroidogenic pathway is affected.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Several reports have shown a relatively high incidence of chromosome anomalies in human inseminated-unfertilized oocytes from infertile women. In the present study, cytogenetic analysis was attempted in 73 human oocytes from 17 fertile women in order to establish the incidence of chromosome anomalies in the fertile population and to compare this with the incidence in inseminated-unfertilized oocytes from infertile women. Of 56 oocytes that could be analysed, 42 oocytes were haploid, 12 were hypohaploid and two exhibited fragmented chromosomes. The low rate of chromosome anomalies (3.6%) found in this population suggests that there is natural selection at fertilization against diploid oocytes and oocytes with fragmented chromosomes. This result also questions the high incidence of chromosome anomalies found in previous reports using inseminated-unfertilized oocytes.

Abstract
OBJECTIVE To present a case with 17,20-desmolase activity deficiency in which in vitro fertilization (IVF) served not only as a therapeutic approach but also as a diagnostic tool for the specificity of the enzymatic deficiency. DESIGN IVF in the patient under study compared with a control group. All women treated with pure follicle-stimulating hormone (FSH). SETTING IVF program at the Instituto Valenciano de Infertilidad. PATIENTS, PARTICIPANTS A patient with primary amenorrhea, who was the subject under study, and seven normally cycling control patients undergoing IVF in the same series. INTERVENTIONS IVF, steroidogenesis in vitro of granulosa-luteal cell obtained at ovum pick-up. MAIN OUTCOME MEASURE(S) Oocyte fertilization and embryo cleavage. Serum and follicular fluid (FF) levels of estradiol (E2), progesterone (P), testosterone (T), androstendione (A), 17 alpha-hydroxyprogesterone (17-OHP). In vitro accumulation of E2 and P. RESULTS Ovulation induction with FSH was successful in achieving follicular development despite low circulating E2. Fertilization and cleavage rates were similar to the control subjects. The patient developed ovarian hyperstimulation. The lack of 17,20-desmolase activity was detected by normal P levels in serum and FF, high 17-OHP, and low T, A, and E2 levels in serum and FF. Granulosaluteal cell cultures in the presence of T restored normal E2 and P production in response to gonadotropins. CONCLUSIONS In patients with 17,20-desmolase deficiency, follicular development, oocyte maturation, and fertilization can take place in a low estrogenic environment.

Abstract
The incidence of ovarian cyst formation during stimulation with additional pituitary suppression was retrospectively studied in 359 patients included in our in-vitro fertilization (IVF) programme. Women were classified according to the type of pituitary desensitization with subcutaneous buserelin used in group A (long protocol; n = 285) and group B (short protocol; n = 74). The rate of appearance of single follicular ovarian cysts for group A was 9.82% and for group B 22.97% (P less than 0.005). Ovarian cystic formations were usually asymptomatic and nonfunctional. The presence of these cysts did not seem to interfere with the ovarian response to stimulation treatment. Oocyte retrieval and pregnancy rate were similar between patients who developed ovarian cysts during gonadotrophin-releasing hormone analogue (GnRHa) therapy and those without cyst formation. These results suggest that ovarian cysts developing during GnRHa treatment are probably the consequence of the initial gonadotrophin rise and that the presence of ovarian cysts in these conditions should not be considered a necessary cause of cancellation for IVF patients.

Abstract
Various antacid or antisecretory agents are used to reduce the risk to patients of aspiration of gastric contents during general anaesthesia and a trial of the gastric proton pump inhibitor, omeprazole, is reported here. Twenty women admitted for elective Caesarean section under general anaesthesia received a single 80-mg oral omeprazole dose at 2000 hours on the evening before surgery. Intragastric pH and volume were measured immediately after induction of anaesthesia and on completion of surgery. Eighty-five percent of pH measurements at induction and extubation and 80% and 95% of volume measurements at induction and extubation respectively met the defined success criteria (pH greater than or equal to 2.5, volume less than 25 ml). Omeprazole treatment was well tolerated by the women and Apgar scores and subsequent progress of the babies were acceptable. These results indicate that gastric acidity and volume were acceptable in the majority of women after omeprazole treatment, but the interval from drug administration to induction of anaesthesia may have been too long in some cases and resulted in unacceptably low pHs.
