Treating Vestibular Migraine When Pregnant and Postpartum: Progress, Challenges and Innovations.

Vestibular migraine is a leading cause of vertigo in pregnancy and, although not a distinct migraine subtype, is an episodic syndrome associated with migraine. Vestibular migraine is associated with diverse symptoms such as vertigo, aura, allodynia, osmophobia, nausea, vomiting and tinnitus, many of which may be exacerbated by, masked or even dismissed in pregnancy. Vestibular migraine is likely an underdiagnosed and undertreated condition in pregnancy. The aetiology of vestibular migraine remains incompletely understood, although various theories have been proposed, including genetic predisposition, neurochemical dysregulation and pro-inflammatory mechanisms, all of which are derived from the pathophysiology of classical migraine. Physiologic changes to the endocrine, haematologic and vascular systems in pregnancy may affect pathophysiological processes in vestibular migraine, and can alter the course of symptoms experienced in pregnancy. These changes also predispose to secondary headache disorders, which may have similar presentations. There has been considerable progress in therapeutic advances in vestibular migraine prophylaxis and treatment outside of pregnancy. There is currently no significant evidence base for acute treatment or prophylaxis for pregnant patients, with treatment recommendations extrapolated from studies on classical migraine, and offered on a benefit versus risk basis. Challenges commonly encountered include difficulty establishing a diagnosis, in addition to recognising and treating neuropsychiatric and gestational co-morbidities. Anxiety, depression, hypertensive disorders and cardiovascular disease are closely associated with migraine, and important contributors to morbidity and mortality during pregnancy. Identifying and treating vestibular migraine during pregnancy offers a unique opportunity to impact future patient health through screening and early treatment of associated co-morbidities. There have been innovations in classical migraine therapy that may confer benefit in vestibular migraine in pregnancy, with emphasis on lifestyle modification, effective prophylaxis, abortive therapies, cognitive behaviour therapy and management of vestibular migraine-related comorbidities.

Managing COVID-19 in pregnant women.

Principles of management of COVID-19 in the general population apply in pregnancy with few exceptions. Clinical inertia can lead to preventable morbidity and mortality. COVID-19 vaccines are safe and should be recommended at any stage of pregnancy. https://bit.ly/3Rj8nWr.

The Use of the Slipping Slipper Sign to Explore the Connection between the Feet and the Mouth in Patients with Diabetes Mellitus.

OBJECTIVE: Both periodontal disease and peripheral neuropathy are complications associated with poorly controlled diabetes. This study aimed to determine whether periodontal disease was more prevalent and more severe among patients with severe diabetic peripheral neuropathy. METHODS: A case-control study was performed; 46 patients with and 48 without the slipping slipper sign (SSS)-a surrogate clinical marker for severe peripheral neuropathy-were recruited from a diabetic outpatient clinic. Demography and data from the Basic Periodontal Examination (BPE) were assessed, in addition to the patients' periodontal health by 2 examiners blinded to patients' SSS status. Multivariate logistic regression was used to evaluate the associations between the risk factors for and the presence of the SSS, adjusting for age, gender, and ethnicity. RESULTS: The mean age of the sample was 55.8 years (±10.69 years). Most of the participants (77.7%) had either never been to a dentist or had last attended a dental clinic more than a year before this examination, and 83% did not have a dentist. Periodontal disease was advanced in 61.7%, and there was no association between the SSS and periodontal disease. Dental-service utilization variables were significantly associated with the SSS. Patients who did not have a regular dentist were more than 7 times more likely to have the SSS than were those who did (OR = 7.70; 95% CI: 1.12 53.21). CONCLUSION: In diabetic patients, oral health-related risk factors, such as not having a dentist, wearing a denture or dentures, and visiting a dentist once a year or more, may be associated with systemic complications, including peripheral neuropathy. Early collaboration between dentists and doctors on the care of patients with diabetes is recommended.

Does the 'slipping slipper sign' in patients with diabetes predict the presence of retinopathy and nephropathy?

BACKGROUND: Previous research had noted that an affirmative response in patients with diabetes to the question 'Have you ever lost your slipper/flip-flop from your feet while walking and not realised that you have done so'? That is, the presence of the 'slipping slipper sign' (SSS) reflected the presence of severe diabetic peripheral neuropathy with a high degree of precision. The objective of the current study was to determine whether the SSS may also predict the presence of diabetic retinopathy and/or nephropathy since microvascular complications are known to cosegregate. SUBJECTS AND METHODS: Among 100 patients with diabetes, including 33 cases with the SSS and 67 controls without the SSS, data on demography, dipstick proteinuria as well as the presence and staging of diabetic retinopathy were obtained. RESULTS: The mean (SD) age of all patients was 54.6 (13.0) years, mean duration of diabetes was 12.7 (10.2) years and mean haemoglobin A1c (HbA1c) 8.42 (1.95) %; 43% were males. All 33 (100%) of the patients with SSS but only 12 (18%) of the patients without SSS were found to exhibit diabetic retinopathy, p<0.001. Among those patients with retinopathy, proliferative retinopathy was far more likely (39%) in the SSS group compared with non-SSS subjects (8%). Similarly, 15 (46%) with SSS and only 4 (6%) without SSS were found to have dipstick proteinuria. The sensitivity of the SSS for retinopathy was 73% and the specificity was 100% with a positive predictive value (PPV) of 100% and negative predictive value (NPV) of 82%. For proteinuria, both the sensitivity and specificity was 78%. CONCLUSIONS: Both diabetic retinopathy and dipstick proteinuria are strongly associated with the presence of the SSS that therefore holds potential as a tool for easier identification of this high-risk group.

Perioperative outcome of colorectal cancer and validation of CR-POSSUM in a Caribbean country.

OBJECTIVE: To evaluate the risk-adjusted perioperative outcome of colorectal cancer surgery, applying the Colorectal Physiological and Operative Severity Score for the enumeration of Mortality and morbidity (CR-POSSUM). METHODS: A retrospective chart review of patients who underwent colorectal cancer surgery from 2004 to 2007 was done. Data including demographics and physiological data for CR-POSSUM were recorded. Predicted mortality was calculated; validation of CR-POSSUM was done using Hosmer-Lemeshow goodness-of-fit and Receiver Operating Characteristic (ROC) Curve analyses. RESULTS: 232 patients were studied. The overall mean CR-POSSUM score was 18.3+/-3.8 (SD). Predicted mortality was 7.7%, observed mortality was 6.9% and the standardized mortality ratio was 0.9. 34.4% of patients presented with Duke's Stage C or D and had a higher risk of mortality (Odds Ratio (OR) 3.1, 95% Confidence Intervals (CI) 1.1, 9.1). Emergency surgery was associated with a higher risk of mortality (OR 4.7, 95% CI 1.5, 14.1). CR-POSSUM calibrated well (Hosmer-Lemeshow Chi-square value 4.3; df: 8; p=0.82) and fairly discriminated outcome as shown by the area under the ROC Curve 0.69, (Standard Error: 0.07). CONCLUSIONS: Perioperative outcome of colorectal surgery in Trinidad and Tobago is comparable to the developed countries as evaluated by the CR-POSSUM. Patients presenting for emergency surgery and those with advanced stages of cancer had higher perioperative mortality.
