Preparing an obstetric unit in the heart of the epidemic strike of COVID-19: quick reorganization tips.

COVID-19 is placing considerable strain on healthcare systems. Disaster and military medicine specialists were involved in the outbreak in Italy, after many units were overwhelmed. Health providers were caught off guard and personnel was unprepared to face this unprecedented threat. Local decisions accelerated the rate of the spread. Many countries declared a state of emergency and lockdown to contain the exponential transmission of the disease. The purpose of this review is to suggest quick key points of strategies to implement in obstetric units without delay to respond to the oncoming wave, based on experience and feedback from the field. It is essential in an emergency situation to understand what is at stake and prepare maternity wards in the best possible way.

Accuracy of clinical diagnosis of anal sphincter defect: clinical evaluation versus 3D-transperineal ultrasound.

BACKGROUND: Obstetric anal sphincter injuries (OASIS) are common and an important factor in the etiology of anal incontinence. The objective of this study was to evaluate, classify and compare the agreement of clinically diagnosed third-degree sphincter tears with 3D-transperineal ultrasound (3D-TPUS) realized within 3-7 days post-delivery. METHODS: This is a retrospective observational study were 119 patients with third-degree obstetric anal sphincter tears were diagnosed and treated, 85 of those underwent a 3D-TPUS examination 3-7 days postpartum. We compared the proportion of third-degree perineal tears, classified with the clinical examination as grade 3a+b and grade 3c, with the 3D-TPUS. RESULTS: In 16 patients with clinically diagnosed third-degree perineal tears grade a and b, the ultrasound examination confirmed the lesion of the external anal sphincter (EAS) muscle, but in nine patients (56% of the cases) we found a lesion of the internal anal sphincter (IAS) muscle, missed by clinical examination. In the remaining 69 patients with the third-degree perineal tears grade c, the ultrasound examination confirmed both lesions (EAS and IAS muscles) in 56 women, but in 13 patients (19% of the cases) defects of the IAS muscle could not be confirmed by the ultrasound. CONCLUSIONS: There was moderate agreement regarding diagnosis of grade 3a+b and grade c perineal tears between ultrasound and clinical examination, so a combined use of clinical and ultrasound knowledge can improve the possibility to find a gold standard in the diagnosis of OASIS.

Postponed pregnancies and risks of very advanced maternal age.

QUESTIONS UNDER STUDY: To evaluate pregnancy outcome in pregnant women aged ≥45 years, termed very advanced maternal age (VAMA). METHODS: We retrospectively compared the outcome of pregnancies in VAMA patients with controls aged 30 years at time of delivery. Subgroups of singleton and multiple pregnancies were also analysed. Incidences of maternal and fetal adverse outcomes were measured. Statistical significance was set at p <0.05. Odds ratios (ORs) were adjusted where necessary. RESULTS: One hundred and twenty-seven VAMA pregnancies and 2066 control pregnancies of women aged 30 years were analysed. VAMA pregnancies had a higher rate of maternal complications such as gestational hypertension (3.9% vs 0.6%; OR 6.5), preeclampsia (14.2% vs 3.0%; OR 5.4, adjusted OR 4.4) and gestational diabetes (12.6% vs 3.6%; OR 3.8). Likewise, increased need for blood transfusion (3.2% vs 0.7%; OR 4.8, adjusted OR 4.4) and prolonged hospitalisation >7 days (37.8% vs 15.1%; OR 3.42) was found. Infant complications such as prematurity (44.9% vs 16.2%; OR 4.2) and low birthweight <5th percentile (11.0% vs 5.6%; OR 2.1) were also increased. CONCLUSION: Pregnant women of very advanced maternal age (≥45 years) have significantly increased maternal and fetal risks. Women postponing pregnancy or planning a pregnancy in very advanced age should be informed about these risks, in particular before artificial reproductive technologies are applied or "social freezing".

Antibiotic resistance patterns among group B Streptococcus isolates: implications for antibiotic prophylaxis for early-onset neonatal sepsis.

STUDY/PRINCIPLES: Antibiotic prophylaxis of Group B Streptococcus (GBS) positive women during labour reduces the risk of early-onset neonatal sepsis. Penicillin is the first choice, and clindamycin and erythromycin are second choices for penicillin-allergic women. Resistance to these antibiotics is rising. The aims of this study were to evaluate the rates of clindamycin and erythromycin resistance among GBS-positive isolates cultures from pregnant women in the University Hospital of Geneva and to evaluate the legitimacy of new Centres for Disease Control and Prevention (CDC) recommendations for our context. METHODS: We collected a vagino-rectal swab from pregnant women at 35-37 weeks gestation. We recovered 124 GBS positive isolates. Identification was based on the characteristic of the colony on the chromogenic agar, the streptococcal agglutination test and confirmation by mass spectrometry. Antimicrobial susceptibility was determined by disk diffusion, according to CLSI guidelines 2010. RESULTS: The rate of resistance to clindamycin was 28% and to erythromycin was 30%. Only 3 of the 38 erythromycin resistant strains (7.9%) were susceptible to clindamycin, and only 3 out of the 35 clindamycin resistant GBS (8.6%) were identified as "inducible resistance". The rate of co-resistance to clindamycin of erythromycin-resistant strains was 92%. Penicillin remained efficacious in all cases. CONCLUSION: Rates of clindamycin and erythromycin resistance are also increasing in our context. These antibiotics should not be used for GBS neonatal sepsis prevention, without adequate antimicrobial susceptibility testing. In case of penicillin allergy and lack of antibiogramm, cephalosporins or vancomycin should be used as recommended in CDC guidelines.

Potential effects of chocolate on human pregnancy: a randomized controlled trial.

OBJECTIVE: This trial was undertaken to evaluate the effects of high-cocoa-content chocolate supplementation in pregnancy on several haematochemical and clinical parameters. The study had as reference population the pregnant women requesting an obstetric control at Outpatient Clinic of Obstetrics and Gynaecology of the S. Maria della Misericordia University Hospital, Perugia, Italy. Candidates who participated in this study were all Caucasian women aged 18-40 years, who had a single gestation pregnancy between 11th + 0 and 13th + 0 week gestational age. METHODS: We conducted a single-center randomized controlled trial. The pregnant women selected were randomized into Group A, which received daily doses of 30 g of chocolate (70% cocoa), and Group B, which was free to increase their diet with other foods. RESULTS: Ninety women were randomized. Significant difference was found between the two groups for diastolic blood pressure (p = 0.05), systolic (p < 0.0001) and levels of liver enzymes, with values lower in Group A than in Group B. Total cholesterol levels and weight gain in Group A did not increase more than in Group B. CONCLUSIONS: A modest daily intake of high-cocoa-content chocolate contributes to reduce blood pressure, glycemic and liver pattern during pregnancy without affecting the weight gain.

Primary breast lymphomas.

The diagnosis, prognostic factors, and optimal management of primary breast lymphomas (PBL) is difficult. Seven patients recorded at the Geneva Cancer Registry between 1973-1998 were reviewed. Five patient had diffuse large B-cell lymphoma, one a follicular lymphoma and one a MALT-lymphoma. All patients had clinical and radiological findings consistent with breast cancer and underwent mastectomy, which is not indicated in PBL. Diagnosis should be established prior to operative interventions, as fine needle aspiration missed the diagnosis for one patient and intra-operative frozen sections for 3 patients in our study. Five-year and 10-year overall survivals were 57% and 15%, respectively. Of the 3 patients who died from PBL, 2 had tumors that were Bcl-2 positive but Bcl-6 negative. All 3 surviving patients have positive Bcl-2 and Bcl-6 immunostaining, which could be important prognostic factors if confirmed by a larger study.

Diagnosis of vulvar lesions by non-invasive optical analysis: a pilot study.

A procedure that could allow an early in vivo and non-invasive detection of vulvar lesions would be extremely useful. We tested an innovative optical method (Optiprobe), which uses a harmless, visible light source for the in vivo, on-line detection of minimal alterations in the structure of vulvar epithelium. A group of 3 female volunteers without gynecological symptoms were first screened to evaluate optical properties of normal vulvar tissue. Next, a group of 16 patients undergoing gynecological examination for vulvar lesions was evaluated by the Optiprobe at suspected sites before these sites were biopsied for histological analysis. Adjacent, non-involved sites were also measured to provide internal controls. Histological analysis of the biopsies identified one case that did not show obvious alterations, 4 cases of high-grade vulvar intraepithelial neoplasia (VIN), 5 cases of vulvitis, and 6 cases of lichen sclerosis (LS).The optical properties of the VIN cases were significantly different from those of controls, due to a decrease in the absorption spectra and an increase in the scattering spectra. In contrast, a significant increase in the absorption spectra and a decrease in the scattering spectra were observed in the cases of vulvitis. In the LS cases, the absorption spectra were as in controls, whereas the scattering spectra were significantly decreased. We conclude that the Optiprobe provides a useful tool for a rapid and non-invasive detection of vulvar alterations. The method should contribute to reduce the number of biopsies and to facilitate the long-term follow-up of vulvar lesions.
