Background. Compliance with medication requires good sense of smell and taste. Objective. To evaluate the olfactory and gustatory function of HIV infected women in Ibadan, Nigeria. Methods. A case control study of women comprising 83 HIV infected women and 79 HIV uninfected women. Subjective self-rating of taste and smell function was by visual analogue scale. Olfactory function was measured via olfactory threshold (OT), olfactory discrimination (OD), olfactory identification (OI), and TDI using “Sniffin' sticks” kits and taste function (Total Taste Strips (TTS) score) measurement was by taste strips. Results. The mean age of the HIV infected women was 43.67 years ± 10.72 and control was 41.48 years ± 10.99. There was no significant difference in the self-reported assessment of smell (p = 0.67) and taste (p = 0.84) of HIV infected and uninfected women. Although the mean OT, OD, OI, TDI, and TTS scores of HIV infected and uninfected women were within the normosmic and normogeusic values, the values were significantly higher in the controls (p < 0.05). Hyposmia was in 39.7% of subjects and 12.6% of controls while hypogeusia was in 15.7% of subjects and 1.3% of controls. Conclusions. Hyposmia and hypogeusia are commoner among the HIV infected women than the HIV uninfected women and the risk increases with an increased duration of highly active antiretroviral therapy.

Objective To investigate the olfactory and gustatory functions of human immunodeficiency virus (HIV)-infected adults in Ibadan, Nigeria. Study Design A cross-sectional study of olfactory and gustatory functions of HIV-infected adults between March 2015 and December 2015. Setting Tertiary health institution. Subjects and Methods A structured questionnaire was administered to participants to obtain relevant sociodemographic and clinical information. Participants' nadir and most recent CD4 cell count and viral loads were obtained from their medical records. Participants' body mass indices were determined, and each subjectively rated their olfactory and gustatory performances. Objective olfactory and gustatory functions were determined using validated "Sniffin' Sticks" and "Taste Strips" impregnated with 4 different concentrations of sucrose, quinine hydrochloride, sodium chloride, and citric acid. Results In total, 135 HIV-infected adults, comprising 41 (30.4%) men and 94 (69.6%) women, were evaluated. Their ages ranged from 20 to 70 years, mean 43.4 ± 10.4 years. Participants were on highly active antiretroviral therapy for a mean duration of 75.8 ± 36.9 months. The proportions of male participants in HIV stages 1, 2, and 3 were 18 (43.9%), 19 (46.3%), and 4 (9.8%), respectively, while female participants were 46 (48.9%), 41 (43.6%), and 7 (7.4%), respectively. Participants' mean olfactory threshold, discrimination, identification, and TDI scores were 8.0 ± 4.9, 9.9 ± 4.7, 8.8 ± 4.5, and 26.7 ± 11.1, respectively, while total taste score was 25.1 ± 5.7. Conclusion HIV-infected adults have tendency to develop hyposmia and hypogeusia. These are worse with advanced stage of HIV infection.

Physiological changes in pregnancy may cause taste dysfunction. The aim of this study was to determine and compare gustatory function of pregnant women with nonpregnant women and also to investigate the effect of pregnancy on gustatory function. It was a case-control study of consecutive 70 healthy pregnant women (cases) and 70 healthy nonpregnant women (control). Participants scored their taste perception on a visual analogue scale (1-10) and their gustatory function was assessed using ''taste strips'' impregnated with graded concentration of sweet, sour, salty, and bitter taste substances applied on tongue surfaces. Subjective mean gustatory score, correct identification of taste in the strips and total taste strip (TTS) score were compared between both groups and analysis was done using appropriate statistics. The mean age of pregnant women (30.5 [3.9]) and controls (28.5 [6.6]) were comparable. Twenty-one (30%) pregnant women changed their diet in first trimester due to change in taste sensation. Almost all cases developed craving for spicy and salty foods and, aversions to fish, beans, and vegetables. There was a significant difference in the subjective rating of taste perception between the 2 groups (P ¼ .037). About 2.9% of pregnant women have hypogeusia. There was a significant difference between pregnant and nonpregnant women in sour taste (P ¼ .006; 2.90 [0.71] vs 3.92 [0.82]) and TTS (P ¼ .02; 27.50 [3.48] vs 29.21 [2.69]) scores, respectively. In conclusion, gustatory function was reduced in pregnancy compared to nonpregnant women and this led to dietary change in some pregnant women.

Pregnant women have olfactory dysfunction more than the non-pregnant women of reproductive age group. Also, they have tendency to develop loss of cognitive olfactory information more than the non-pregnant women.

Sjögren's syndrome, an immune-mediated disorder of the exocrine glands (lacrimal and salivary) affects acinar cell serous production leading to complaints of dryness of the eyes and mouth. Radiological imaging has been used as a non-invasive modality for the diagnosis of this condition. This is a case report of incidental diagnosis of Sjögren's syndrome in a 49-year-old female with left aural fullness and recurrent tinnitus. Incidental findings of scattered micro-calcifications and heterogeneity were seen in both parotid glands on computed tomography imaging and innumerable microcysts of low signal intensity on T1 and high signal intensity on T2/STIR, on magnetic resonance imaging of the temporal bone. These findings are pathognomonic for Sjögren's syndrome.The meticulous review of computed tomography and magnetic resonance images help to detect silent lesions and the awareness of audio-vestibular involvement in Sjögren's syndrome can lead to prompt diagnosis and the monitoring of disease progression.
