Position paper on olfactory dysfunction: 2023

BACKGROUND

Since publication of the original Position Paper on Olfactory Dysfunction in 2017 (PPOD-17), the personal and societal burden of olfactory disorders has come sharply into focus through the lens of the COVID-19 pandemic. Clinicians, scientists and the public are now more aware of the importance of olfaction, and the impact of its dysfunction on quality of life, nutrition, social relationships and mental health. Accordingly, new basic, translational and clinical research has resulted in significant progress since the PPOD-17. In this updated document, we present and discuss currently available evidence for the diagnosis and management of olfactory dysfunction. Major updates to the current version include, amongst others: new recommendations on olfactory related terminology; new imaging recommendations; new sections on qualitative OD and COVID-19 OD; updated management section. Recommendations were agreed by all co-authors using a modified Delphi process.

CONCLUSIONS

We have provided an overview of current evidence and expert-agreed recommendations for the definition, investigation, and management of OD. As for our original Position Paper, we hope that this updated document will encourage clinicians and researchers to adopt a common language, and in so doing, increase the methodological quality, consistency, and generalisability of work in this field.

Effect of Administrating Coenzyme Q10 with Clomiphene Citrate on Ovulation Induction in Polycystic Ovary Syndrome Cases with Resistance to Clomiphene Citrate: A Randomized Controlled Trial

Background:

The purpose of this study was to assess the effect of combining low dose of Coenzyme Q10 with clomiphene citrate on ovulation induction in polycystic ovary syndrome (PCOS) women with clomiphene resistance.

Methods:

A total of 149 women with clomiphene resistant PCOS who needed ovulation induction were randomly allocated to oral clomiphene citrate and Coenzyme Q10 group and oral clomiphene citrate only group using a computer generated allocation sequence. The study was conducted at Aziz Medical Center, Karachi, Pakistan from 1st July 2020 to 1st October 2020. Polycystic ovary syndrome was diagnosed according to Rotterdam criteria. The primary outcome was ovulation and conception rate per cycle. Chi square test and Fischer’s exact test were used to compare these variables at p<0.05 level of significance.

Results:

Of the 133 women assessed, the proportion of women who ovulated with combination (70% vs., 19%, p=0.001) was greater and the combination group had greater conception rate per cycle than those who received only clomiphene (48.6% vs. 6.3%, p<0.001). When stratified according to obesity, 85.3% of non-obese women who received combination ovulated whereas only 55.6% of obese women ovulated (p=0.002). Moreover, 48.6% of non-obese women conceived in the combination group as compared to 6.3% of obese women (p=0.007). Women who received combination were six times more likely to conceive than women who only received clomiphene citrate (AOR=6.344, 95% CI: 1.452–27.71, p=0.014).

Conclusion:

Coenzyme Q10 is a valuable adjunct in women with PCOS undergoing ovulation induction. It improves ovulation and conception in women with clomiphene resistance.

Triaging Women with Pregnancy of Unknown Location: Evaluation of Protocols Based on Single Serum Progesterone, Serum hCG Ratios, and Model M4

Background:

The purpose of the current study was to evaluate the ability of three protocols to triage women presenting with pregnancy of unknown location (PUL).

Methods:

Women with pregnancy of unknown location were recruited from Aziz Medical Centre from 1st August, 2018 to 31st July, 2020. The criterion of progesterone, human chorionic gonadotrophin (hCG) ratio, and M4 algorithm were used to predict risk of adverse pregnancy outcomes and classify women. Finally, 3 groups were established including ectopic pregnancy, failed pregnancy of unknown location, and intrauterine pregnancy (IUP). The primary outcome was to assign women to ectopic pregnancy group using these protocols. The secondary outcome was to compare the sensitivity and specificity of the three protocols relative to the final outcome.

Results:

Of the 288 women, 66 (22.9%) had ectopic pregnancy, 144 (50.0%) had intrauterine pregnancy, and 78 (27.1%) had failed pregnancy of unknown location. The criterion of progesterone had a sensitivity of 81.8%, specificity of 27%, negative predictive value (NPV) of 83.3%, and positive predictive value (PPV) of 25% for high risk result (ectopic pregnancy). The hCG ratio had sensitivity of 72%, specificity of 73%, NPV of 90%, and PPV of 44% for high risk result (ectopic pregnancy). However, model M4 had sensitivity of 86.4%, specificity of 91.9%, NPV of 95.8%, and PPV of 76% for high risk result.

Conclusion:

Based on the findings of the study, it was revealed that prediction model of M4 had the highest sensitivity, specificity, negative predictive value and positive predictive value for high risk result (ectopic pregnancy).

Pregnant during the COVID-19 pandemic: Knowledge, concerns, attitudes and practices of Pakistani women

INTRODUCTION

Data regarding pregnancy and related outcomes with COVID-19 are inconsistent, which leads to difficulties in counselling pregnant women. This brings uncertainty to pregnant women regarding mode of birth, transmission and issues that may occur in case they contract the disease. We conducted this study to assess the knowledge about COVID-19 risk during pregnancy and childbirth and to assess the concerns, attitudes, and practices of pregnant women during the pandemic.

METHODS

A cross-sectional survey was carried out among 376 consenting pregnant women attending antenatal clinics in Karachi, Pakistan, between 1 July and 16 July 2020, using pretested questionnaires.

RESULTS

A total of 376 pregnant women participated in the survey. Participants had inadequate knowledge about COVID-19 risk during pregnancy, including potential vertical transmission (58.5%), preferred route of delivery (52%), safety of breastfeeding (50%), birth defects (44.7%), rooming in and skin-to-skin contact (58.5%). The majority (85.1%) had a high concern score, and negative attitude (62.8%). Only 43.6% said that they would not hide their symptoms, while 37.2% stated that they will deliver at hospital if they tested positive. Only 30.9% of respondents had good practices. During visits, 39.4% maintained social distancing and sanitized hands while only 37.2% said that they did not bring more than one person with them.

CONCLUSIONS

The study population had inadequate knowledge, negative attitude, and poor practices regarding pregnancy during the COVID-19 pandemic. More than half of the respondents thought that concealing symptoms and delivering at home would be better. Awareness programs are urgently needed.

Anti-phospholipid antibodies in women presenting with preterm delivery because of preeclampsia or placental insufficiency

Objective:

To assess the proportion of women presenting with preterm delivery because of preeclampsia or placental insufficiency (PREPI) with anti-phospholipid antibodies (APLA).

Material and Methods:

This was a prospective cohort study conducted at an obstetrics and gynecology department. Women, aged 20-40 years, with preeclampsia who delivered before 34 weeks were cases while those who delivered before 34 weeks but did not have preeclampsia acted as controls. Both groups had APLA measured at diagnosis and 12-weeks postnatally. Anti-phospholipid antibody syndrome (APS) was diagnosed according to Sapporo’s criteria.

Results:

The study included 98 cases and 106 controls. Both cases and controls were similar in terms of age, gestational age and parity. The frequency of APS positivity was 17.3% in cases but only 3.8% in controls (p=0.001). Cases were more likely to be of Baloch ethnicity (34.7% vs. 11.3%, p=0.001), have a history of miscarriage (25.5% vs. 13.2%, p=0.026), use aspirin (p<0.001) or low molecular weight heparin (p<0.001), and be obese (p<0.001) than controls. Cases were more likely to have lupus anticoagulant antibodies (82.4% vs. 75%).

Conclusion:

Our study confirms a high prevalence of APLA in women who have preterm delivery due to PREPI. An opportunity to screen these women should be made, so that proper counselling can be given and future pregnancies can be managed in an appropriate and timely manner.

Frequency of pregnant women who accept HIV screening using rapid detection test and factors associated with acceptance

To assess the frequency of pregnant women who accept HIV screening using rapid detection test and factors associated with acceptance we undertook a cross-sectional study conducted from July to December 2018. Women aged 20–45 years, who were pregnant and planned to deliver at the facility, were included. Women were counseled and offered about Human Immunodeficiency virus (HIV) screening. A total of 718 women were included in the study. The screening was accepted by 32.3% of women. Six women tested positive in the study giving a seroprevalence of 0.8% in the population studied. Acceptance of counseling and screening varied significantly with age range, educational status, socioeconomic status, and employment status. Women aged 30 years and above ( p = 0.023) and women with higher education ( p < 0.001) were more likely to refuse counselling. Similarly, employed women (p = 0.041) and women of higher socioeconomic class ( p = 0.039) refused counselling. However, when logistic regression was conducted, only educational status ( p < 0.001) and occupational status ( p = 0.039) were significantly associated with acceptance of counseling and screening. The acceptance of counselling and testing for HIV in antenatal care attendees was low. Women of higher educational status and having some employment refused counselling and testing more commonly.

Knowledge and practices: Risk perceptions of COVID-19 and satisfaction with preventive measures at workplace among maternity care providers in Pakistan

INTRODUCTION

While all healthcare services across the globe deferred non-urgent surgeries, labor wards provided maternity care during the COVID-19 pandemic continuously. This study assesses the knowledge and practices of obstetricians and midwives about personal protective equipment (PPE); their risk perception of COVID-19 and satisfaction with the preventive measures adopted at their workplace.

METHODS

A questionnaire designed according to the World Health Organization’s advice on rational use of personal protective equipment for COVID-19 was administered to 452 Pakistani maternity care providers between 1 July and 30 July 2020.

RESULTS

Most (85%) had adequate knowledge and 78.8% had good practices regarding PPE use. The perceived risk of contracting COVID-19 was lower than for influenza and tuberculosis. Perceived risk of contracting COVID-19 was highest for outpatient clinics. Fewer midwives compared to obstetricians (23.3% vs 32.9 %, p=0.001) were satisfied with the job security provided. Only 19.5% were satisfied with the social distancing measures at their setups. Less than one-third (31%) were satisfied with the PPE available to them.

CONCLUSIONS

The participants had good knowledge and practices regarding PPE. The perceived risk of contracting COVID-19 was lower than for contracting influenza; however, they were concerned about contracting COVID-19 in outpatient clinics and emergency rooms. They had poor satisfaction with the measures adopted by hospital managements regarding job security and social distancing.

Pessary offer documentation in women undergoing surgery for pelvic organ prolapse at a tertiary care hospital

BACKGROUND

Women report similar functional outcomes after pessary treatment or surgery for pelvic organ prolapse (POP).

AIMS

To assess the documentation of pessary counselling in women who underwent surgery for POP. Methods: This was a retrospective cohort study conducted on women who underwent hysterectomy for prolapse. The primary outcome measure was documentation regarding offer of pessary. 'Pessary offer' was defined as documentation that clearly stated that the care provider offered pessary to the patient.

FINDINGS

Over the study period, 81 hysterectomies took place for POP; pessary offer was documented for only 19 (23.5%) case records. Characteristics significantly associated with pessary offer were history of chronic cough (P=0.031), previous pelvic surgery (P<0.001), no secondary indication for surgery (P=0.012), concomitant surgery performed other than hysterectomy (P=0.046), age range (P<0.001) and BMI range (P<0.001).

CONCLUSION

Pessary offer was documented in less than quarter of cases. This denotes a need to strengthen documentation of offer, counselling for pessary, or both of these.

Femiject, a once-a-month combined injectable contraceptive: experience from Pakistan

OBJECTIVES

The aims of the study were to compare the 12 month continuation rate, level of satisfaction and bleeding patterns of a once-a-month combined injectable contraceptive (CIC; Femiject), a 3 monthly progestogen-only injectable contraceptive (depot medroxyprogesterone acetate [DMPA]) and combined oral contraceptives (COCs).

METHODS

A prospective observational study was conducted at Aziz Medical Centre, Karachi, Pakistan. The study comprised 171 married women aged 19-35 years and requesting contraception. Participants were offered injectable contraceptives or COCs and evaluated twice: once at the beginning of the study and again after 12 months, or earlier if they discontinued use.

RESULTS

Sixty (35.1%) women chose COCs, 53 (31.0%) chose DMPA and 58 (33.9%) chose the CIC. The continuation rate was higher among CIC users (p = .034). CIC users were more satisfied with their method compared with those who chose COCs or DMPA (63.8% vs 25.0% and 28.3%, respectively). Most CIC users said they were likely or very likely to use the method again (63.8%); only 25.9% said they would not recommend it to a friend. CIC users had, however, more spotting compared with COC users (60.3% vs 3.3%; p ˂ .001).

CONCLUSION

As the continuation rate, level of satisfaction and bleeding profile of CIC users was promising, increased uptake should be encouraged. Our study shows that CIC is a good option for women requesting contraception.

Cervical stenosis and pregnancy rate after ultrasound guided cervical dilation in women undergoing saline infusion sonography

Aim

To assess the effect of ultrasound-guided cervical dilation on clinical pregnancy rates in women with cervical stenosis.

Methods

A prospective case control study was conducted in women with unexplained infertility. These women underwent saline infusion sonography and were suspected of having cervical stenosis if a 7 French Foley’s catheter could not be introduced into the cervical canal. Women with suspected stenosis who agreed to undergo ultrasound guided dilation were included as cases. Those with suspected stenosis who refused dilation were used as controls. Both groups were followed for one year. The primary outcome measure was women who had clinical pregnancy i.e. fetal heart beat present on transvaginal scan during the follow up period.

Results

During the study period, 1097 women who underwent SIS were included. A total of 117 (10.7%) patients had cervical stenosis. No statistically significant difference was there in both groups in terms of mean age (p = 0.617), mean body mass index (p = 0.598), duration of infertility (p = 0.588) and type of infertility (p = 0.167). However, both groups were significantly different in terms of history for risk factors i.e. endometriosis (p <0.001), prior surgery (p <0.001), polyps (p = 0.004) and pelvic inflammatory disease (p = 0.001). Eighty-nine women agreed to have dilation and were used as cases and 28 women refused and were used as controls. Of the cases, 70.45% conceived as compared to 18.5% of controls. The mean time to conception in months was also significantly lower in cases (8.10 ± 3.43 vs. 11.39 ± 1.97, p <0.001).

Conclusions

Our study shows that ultrasound-guided cervical dilation in women with cervical stenosis can lead to improved conception rates.
