Relation of Daytime Bradyarrhythmias With High Risk Features of Sleep Apnea
No full textBradyarrhythmias (BA) have been reported in patients with sleep apnea (SA), but the incidence of SA in patients with BA remains unclear. A case-control study was conducted to assess the prevalence of high-risk features of SA in patients with documented BA on 24-hour Holter monitoring compared with patients without BA. Controls were age-matched patients selected from those with no evidence of BA on 24-hour Holter monitoring. BA were defined as the presence of pauses of 3 seconds, regardless of the mechanism, and-or heart rate 40 beats-min during presumed waking hours (8 a.m. to 8 p.m.). High-risk features of SA were determined by the Berlin Questionnaire, with positive results defined as having '2 of 3 positive high-risk categories. Body mass index (BMI), hypertension, β-blocker use, and other underlying characteristics were cataloged. Nineteen patients with documented BA and 47 with no BA were identified. The mean ages and BMIs in the active and control groups were not statistically significant. High-risk features for SA were present in 57.8percent of patients in the BA group compared with 21.3percent in the control group (p = 0.003). After controlling for age, BMI, hypertension, and β-blocker use, patients with BA were 6 times more likely to have high-risk features of SA compared with those without BA (logistic regression odds ratio 6.1, 95percent confidence interval 1.5 to 24, p = 0.012). In conclusion, irrespective of BMI, age, and other underlying risk factors, the presence of daytime BA was highly associated with high-risk features of SA. © 2008 Elsevier Inc.

The Relationship between Postpartum Depression and Breastfeeding
No full textIntroduction: The purpose was to investigate the possible correlation or predictive relationship between breastfeeding and Postpartum Depression (PPD). Method: We conducted a prospective study in which 137 Arab women were assessed during pregnancy and postpartum. Current breastfeeding was correlated with postpartum outcomes (EPDS and MINI), employment, and use of formula at 2 and 4 months postpartum, as well as with other variables. Results: Women who were breastfeeding at 2 and 4 months had lower scores on EPDS (p 0.0037 and p 0.0001, respectively) and were less likely to be diagnosed with PPD at 4 months (p 0.0025). Higher scores on EPDS and diagnosis of PPD at 2 months were predictive of lower rates of breastfeeding at 4 months (p 0.0001 and p 0.005, respectively). Women who were employed and using formula at 2 months were less likely to breastfeed at 4 months (p 0.0001). Breastfeeding women at 2 months had lower scores on EPDS (p 0.003) and were less likely to be diagnosed with PPD (p 0.05) at 4 months. Discussion: The results indicate that women who breastfeed their infants reduced their risk of developing PPD, with effects being maintained over the first 4 months postpartum. PPD may also decrease the rate of breastfeeding, suggesting a reciprocal relationship between these variables. © 2012 Baywood Publishing Co., Inc.Abou-Saleh MT, 1998, PSYCHONEUROENDOCRINO, V23, P465; Beck CT, 2001, NURS RES, V50, P275, DOI 10.1097-00006199-200109000-00004; McCoy Sarah J Breese, 2006, J Am Osteopath Assoc, V106, P193; Dennis CL, 2009, PEDIATRICS, V123, pE736, DOI 10.1542-peds.2008-1629; Dunn S, 2006, JOGNN-J OBST GYN NEO, V35, P87, DOI 10.1111-J.1552-6909.2006.00005.x; Galler JR, 1999, J DEV BEHAV PEDIATR, V20, P80, DOI 10.1097-00004703-199904000-00002; Ghubash R, 1997, SOC PSYCH PSYCH EPID, V32, P474; Ghusbash R, 2009, PSYCHOL REP, V105, P127; Green Katherine, 2006, Psychol Health Med, V11, P425, DOI 10.1080-13548500600678164; Hamdan A, 2011, ARCH WOMEN MENT HLTH, V14, P125, DOI 10.1007-s00737-010-0189-8; Hatton DC, 2005, J HUM LACT, V21, P444, DOI 10.1177-0890334405280947; Ip S, 2009, BREASTFEED MED, V4, pS17, DOI 10.1089-bfm.2009.0050; Kavanaugh K, 1997, J Hum Lact, V13, P15, DOI 10.1177-089033449701300111; Kehler HL, 2009, CAN J PUBLIC HEALTH, V100, P376; Kelly YJ, 2005, PUBLIC HEALTH NUTR, V8, P417, DOI 10.1079-PHN2004702; Kendall-Tackett Kathleen, 2007, Int Breastfeed J, V2, P6, DOI 10.1186-1746-4358-2-6; Kimbro RT, 2006, MATERN CHILD HLTH J, V10, P19, DOI 10.1007-s10995-005-0058-7; Labbok MH, 2001, PEDIATR CLIN N AM, V48, P143, DOI 10.1016-S0031-3955(05)70290-X; Lecrubier Y, 1998, EUR PSYCHIAT, V13, P198, DOI 10.1016-S0924-9338(98)80004-7; LOCKLIN MP, 1993, BIRTH-ISS PERINAT C, V20, P30, DOI 10.1111-j.1523-536X.1993.tb00176.x; OHara MW, 1996, INT REV PSYCHIATR, V8, P37, DOI 10.3109-09540269609037816; Robertson E, 2004, GEN HOSP PSYCHIAT, V26, P289, DOI 10.1016-j.genhosppsych.2004.02.006; Sheehan DV, 1998, J CLIN PSYCHIAT, V59, P22, DOI 10.4088-JCP.09m05305whi; Stewart DE, 2003, POSTPARTUM DEPRESSIO; SUSMAN VL, 1988, AM J PSYCHIAT, V145, P498; Taveras EM, 2003, PEDIATRICS, V112, P108, DOI 10.1542-peds.112.1.108; Vogel A, 1999, ACTA PAEDIATR, V88, P1320, DOI 10.1080-08035259975003001321
Effect of Pregnancy on the Speaking Voice
No full textThe study aims to investigate the vocal symptoms and acoustic changes in pregnant women pre- and postpartum in comparison to the controls. A total of 25 pregnant women who presented for delivery were enrolled in this study. Twenty-one nonpregnant women were matched as controls. Vocal symptoms such as hoarseness, vocal fatigue, and aphonia were assessed. Acoustic analysis included fundamental frequency (F0), habitual pitch, relative average perturbation (RAP), shimmer, noise-to-harmony ratio (NHR), and maximum phonation time (MPT). There were no significant differences in the incidence of vocal symptoms in pregnant women versus controls. However, vocal fatigue was more prevalent in the pregnant group. With respect to the acoustic parameters, there was a significant decrease in the MPT at term. The rest of the variables were comparable. Postpartum, the MPT significantly increased and there was an increase in F0 and a significant decrease in the voice turbulence index (VTI). Pregnant women have more vocal fatigue and a reduction in MPT compared to the controls. Immediately after delivery, there is a significant increase in MPT. © 2009 The Voice Foundation.Abitbol J, 1999, J VOICE, V13, P424, DOI 10.1016-S0892-1997(99)80048-4; ABITBOL J, 2006, ODESSY VOICE; BRODNITZ FS, 1979, ARCH OTOLARYNGOL, V105, P300; Cunningham G, 2005, WILLIAMS OBSTET; VERDOLINIMARSTON K, 1990, J VOICE, V4, P142, DOI 10.1016-S0892-1997(05)80139-0; DURR JA, 1987, AM J KIDNEY DIS, V9, P276; Ellegard E, 2000, GYNECOL OBSTET INVES, V49, P98, DOI 10.1159-000010223; Finkelhor B.

Effect of fasting on voice in males
No full textPurpose of the study: The aim of the study was to study how fasting between 12 and 14 hours affects voice production. Study design: This is a prospective study of male subjects. Material and method: A total of 26 healthy male subjects were recruited for the study. The age varied between 22 and 50 years with a mean of 28 years. Exclusion criteria included hoarseness at the time of presentation, history of recent upper respiratory tract infection, or microlaryngeal surgery. Subjects were evaluated while fasting and nonfasting. Each subject was asked about vocal fatigue and ease of phonation. This was followed by acoustic analyses and laryngeal videostroboscopy. Results: The incidence of vocal fatigue was not higher while fasting compared to nonfasting (P = 1.00). Phonatory effort was significantly greater during fasting (P .001). Fifty percent of the subjects had an increase in their phonatory effort. There was a significant decrease in the habitual pitch, voice turbulence index, and noise-to-harmonic ratio (P = .018, .045, and .001, respectively). There were no laryngeal videostroboscopic changes. Conclusion: Fasting in males results in an increase in phonatory effort. These phonatory changes may be secondary to dehydration as well as overall neuromuscular fatigability. © 2011 Elsevier Inc.

A simulation model for reliability-based appraisal of an energy policy: The case of Lebanon
No full textThe Lebanese Electric Power System (LEPS) has been suffering from technical and financial deficiencies for decades and mirrors the problems encountered in many developing countries suffering from inadequate or no power systems planning resulting in incomplete and ill-operating infrastructure, and suffering from effects of political instability, huge debts, unavailability of financing desired projects and inefficiency in operation. The upgrade and development of the system necessitate the adoption of a comprehensive energy policy that introduces solutions to a diversity of problems addressing the technical, financial, administrative and governance aspects of the system. In this paper, an energy policy for Lebanon is proposed and evaluated based on integration between energy modeling and financial modeling. The paper utilizes the Load Modification Technique (LMT) as a probabilistic tool to assess the impact of policy implementation on energy production, overall cost, technical-commercial losses and reliability. Scenarios reflecting implementation of policy projects are assessed and their impacts are compared with business-as-usual scenarios which assume no new investment is to take place in the sector. Conclusions are drawn on the usefulness of the proposed evaluation methodology and the effectiveness of the adopted energy policy for Lebanon and other developing countries suffering from similar power system problems. © 2012 Elsevier Ltd.Abi Said C., 2005, ELECT ENERGY ENERGY; Al-Shaalan A.M., 2011, J KING SAUD U ENG SC, V23, P27; Avetisyan M, 2006, ENERG ECON, V28, P455, DOI 10.1016-j.eneco.2005.12.001; Badelt G, 2000, ENERG POLICY, V28, P39, DOI 10.1016-S0301-4215(99)00085-3; BILLINTON R, 1978, IEEE T POWER AP SYST, V97, P2076, DOI 10.1109-TPAS.1978.354711; Billinton R, 1996, RELIABILITY EVALUATI; D'Sa A, 2005, ENERG POLICY, V33, P1271, DOI 10.1016-j.enpol.2003.12.003; Electricite du France, 2009, GEN TRANS MAST PLAN; El-Fadel M, 2003, RENEW ENERG, V28, P1257, DOI 10.1016-S0960-1481(02)00229-X; El-Fadel R.H., 2009, ENERG POLICY, V38, P751; Ghajar R., 2011, P 8 INT C EUR EN MAR; Hamdan H.A., 2010, THESIS LEB AM U BYBL; IEEE Reliability Test System, 1979, IEEE T POWER APPARAT, V98, P2047; Karaki SH, 2002, INT J ELEC POWER, V24, P611, DOI 10.1016-S0142-0615(01)00075-8; Ministry of Energy and Water, 2003, IPP EN PROJ EN POL S; Ministry of Energy and Water, 2010, POL PAP EL SECT; Ministry of Energy and Water, 2009, FORM MED LONG TERM F; Ministry of Energy and Water, 2005, IPP EN PROJ EN POL S; Ministry of Energy and Water, 2004, IPP EN PROJ BLUEP ES; World Bank, 2008, 41421LB WORLD BANK33
Vocal characteristics in patients with thyroiditis
No full textObjective: The aim of the present study was to describe the vocal characteristics of patients with thyroiditis in a clinical setting. Materials and methods: A total of 17 consecutive patients with the diagnosis of thyroiditis presenting to the endocrinology clinic were invited to participate in the study. A group of 29 healthy subjects were used as controls. They underwent acoustic analysis and a perceptual evaluation using the GRABS classification. The mean score of each parameter was computed, and the distribution of severity of each perceptual parameter were listed. Results: There was no significant difference in any of the acoustic parameters between the patients and the controls, and there was no significant difference in the mean score of all the perceptual parameters between the patients and the controls. Even when examining the distribution of the severity of evaluation, there was no significant difference between the patients and the controls, as well. Conclusion: Patients with thyroiditis do not have abnormal perceptual vocal evaluation or acoustic findings compared with controls. © 2012 Elsevier Inc.Belafsky PC, 2002, J VOICE, V16, P274, DOI 10.1016-S0892-1997(02)00097-8; Caroline M, 2012, J VOICE, V26, P262, DOI 10.1016-j.jvoice.2010.11.007; Caturegli P, 2007, CURR OPIN RHEUMATOL, V19, P44, DOI 10.1097-BOR.0b013e3280113d1a; Dedivitis RA, 2007, REV BRAS OTORRINOLAR, V73, P144, DOI 10.1590-S0034-72992007000100028; Gharahbaghian Laleh, 2007, West J Emerg Med, V8, P97; Hamdan AL, 2006, ARCH OTOLARYNGOL, V132, P547, DOI 10.1001-archotol.132.5.547; HARPER MB, 1989, J FAM PRACTICE, V29, P382; Heman-Ackah Yolanda D, 2006, J Voice, V20, P269, DOI 10.1016-j.jvoice.2005.03.010; Hussain M, 2008, ASIAN J SURG, V31, P59, DOI 10.1016-S1015-9584(08)60059-7; LANGEVITZ P, 1983, POSTGRAD MED J, V59, P726; LINDEM MC, 1969, AM J SURG, V118, P829, DOI 10.1016-0002-9610(69)90240-2; LUCAROTTI ME, 1988, BRIT J SURG, V75, P1041, DOI 10.1002-bjs.1800751030; McManus C, 2011, J SURG RES, V170, P52, DOI 10.1016-j.jss.2011.01.037; SAKIYAMA R, 1993, AM FAM PHYSICIAN, V48, P615; Tsudana T, 1991, JAPANESE J SURG, V21, P450; VOLPE R, 1957, Can Med Assoc J, V77, P297; WEETMAN AP, 1994, ENDOCR REV, V15, P788, DOI 10.1210-er.15.6.7880
Correlation between the length and sagittal projection of the upper and lower jaw and the fundamental frequency
No full textObjective To report on the correlation between the length and projection of the upper and lower jaw and the fundamental frequency (F0). Study Design Prospective study. Materials and Methods A total of 45 healthy subjects were included in this study. The facial skeletal measurements included: SNA, SNB, ANB, angles that reflect the position of the maxilla and mandible in relation to the base of skull and to each others, length of mandible Co-Gn, and length of maxilla PNS-ANS. All subjects underwent acoustic analysis using VISI-PITCH IV. Results The means for F0 and habitual frequency were 220.75 + 40.01 Hz and 216.99 + 43.9 Hz, respectively. The means for SNA, SNB, and ANB were 80.753 ± 3.20, 77.409 ± 3.64, and 3.336 ± 2.57, respectively. The mean length of the mandible and maxilla were 104.28 + 7.94 and 50.29 + 3.94, respectively. In the total group, there was a moderate negative correlation between F0 and habitual frequency and the length of the mandible (r =-0.528 and-0.577, respectively). There was also a moderate negative correlation between F0 and habitual frequency and the length of the maxilla (r =-0.473 and-0.519, respectively). Similar findings were present after excluding the pubertal subjects. With respect to the other cephalometric measurements, the correlation was poor (r value andlt; 0.3). Conclusions There is a moderate negative correlation between the length of the upper and lower jaw and the average F0 and habitual frequency. The remaining facial sagittal projection parameters do not correlate with the average F0 and habitual frequency. © 2014 The Voice Foundation.Chanchareonsook N, 2006, CLEFT PALATE-CRAN J, V43, P477, DOI 10.1597-05-001R1.1; Chen JY, 2002, AM J ORTHOD DENTOFAC, V122, P470, DOI 10.1067-mod.2002.126730; Cheung L K, 2008, Ann R Australas Coll Dent Surg, V19, P133; Collins SA, 2000, ANIM BEHAV, V60, P773, DOI 10.1006-anbe.2000.1523; Cura N, 1997, EUR J ORTHODONT, V19, P691, DOI 10.1093-ejo-19.6.691; Dabbs JM, 1999, PERS INDIV DIFFER, V27, P801, DOI 10.1016-S0191-8869(98)00272-4; Ghafari J, 1998, AM J ORTHOD DENTOFAC, V113, P51, DOI 10.1016-S0889-5406(98)70276-8; Hamdan AL, 2012, J VOICE, V26, P144, DOI 10.1016-j.jvoice.2011.01.011; Illing HM, 1998, EUR J ORTHODONT, V20, P501, DOI 10.1093-ejo-20.5.501; Jorge TM, 2009, J CRANIOFAC SURG, V20, P161, DOI 10.1097-SCS.0b013e3181945a64; KAHANE JC, 1982, J SPEECH HEAR RES, V25, P446; KUNZEL HJ, 1989, PHONETICA, V46, P117; LASS NJ, 1978, J ACOUST SOC AM, V63, P1218, DOI 10.1121-1.381808; LIEBERMAN P, 1962, J ACOUST SOC AM, V34, P922, DOI 10.1121-1.1918222; Lim M, 2006, J VOICE, V20, P46, DOI 10.1016-j.jvoice.2004.09.003; Marunick MT, 2000, J VOICE, V14, P82, DOI 10.1016-S0892-1997(00)80097-1; McComb RW, 2011, J ORAL MAXIL SURG, V69, P2226, DOI 10.1016-j.joms.2011.02.142; Moorrees CFA, 2006, RADIOGRAPHIC CEPHALO, P153; NELSON C, 1993, AM J ORTHOD DENTOFAC, V104, P153, DOI 10.1016-S0889-5406(05)81005-4; Newman SR, 2000, J VOICE, V14, P72, DOI 10.1016-S0892-1997(00)80096-X; Pereira V, 2008, CLEFT PALATE-CRAN J, V45, P353, DOI 10.1597-07-042.1; Peterson M, 1997, ACTA U OUL D, V401, P19; Proffit WR, 2007, CONT ORTHODONTICS, P27; Roers F, 2009, J ACOUST SOC AM, V125, P503, DOI 10.1121-1.3026326; Satoh K, 2004, CLEFT PALATE-CRAN J, V41, P355, DOI 10.1597-02-153.1; Sherer KR, 1979, SOCIAL MARKERS SPEE, P147; Sperber GH, 2006, SEMIN ORTHOD, V12, P4, DOI 10.1053-j.sodo.2005.10.003; Steiner CC, 1960, AM J ORTHOD, V46, P721, DOI 10.1016-0002-9416(60)90145-7; Trudgill Peter, 1974, SOCIAL DIFFERENTIATI; Tulloch JFC, 1997, AM J ORTHOD DENTOFAC, V111, P391, DOI 10.1016-S0889-5406(97)80021-2; vanDommelen WA, 1995, LANG SPEECH, V38, P267; Webster T, 1996, AM J ORTHOD DENTOFAC, V110, P46, DOI 10.1016-S0889-5406(96)70086-00
Prevalence of adenoid hypertrophy in adults with nasal obstruction
No full textObjective: To assess the prevalence of adenoid hypertrophy in adults presenting with nasal obstruction. Design: A prospective study was conducted. Descriptive analysis was used for statistical analysis. Setting: Fifty-five patients above the age of 17 years who presented with nasal obstruction were enrolled in the study. Forty-nine patients with no history of nasal obstruction were matched according to age and gender as controls. Allergy, pattern of nasal obstruction (continuous vs intermittent and unilateral vs bilateral), and symptoms such as nasal discharge, postnasal drip, headache, and facial pain were investigated in relation to the presence or absence of adenoid hypertrophy. Nasal findings such as the presence of intranasal polyps and potency of the osteomeatal complex were also reviewed. Results: The overall prevalence of adenoid hypertrophy in adults with nasal obstruction approached 63.6percent in patients with nasal obstruction and 55.1percent in the control group (p 5 .007). Conclusion: Adenoid hypertrophy is often underestimated in adults with nasal obstruction. The presence of purulent nasal discharge should stimulate the caring physician to do nasal endoscopy for proper diagnosis. © 2008 The Canadian Society of Otolaryngology-Head and Neck Surgery.BARZAN L, 1990, ARCH OTOLARYNGOL, V116, P928; BAUCHA V, 2004, EAACI C ST LOUIS MOS; Benito MB, 1999, INT J PEDIATR OTORHI, V51, P145, DOI 10.1016-S0165-5876(99)00250-5; Bernstein JM, 2001, OTOLARYNG HEAD NECK, V125, P593, DOI 10.1067-mhn.2001.120232; BRITTON PD, 1989, J LARYNGOL OTOL, V103, P71, DOI 10.1017-S0022215100108060; BRODSKY L, 1988, LARYNGOSCOPE, V98, P1055; BRODSKY L, 1993, ARCH OTOLARYNGOL, V119, P821; BROOK I, 1981, LARYNGOSCOPE, V91, P377; Clemens J, 1998, INT J PEDIATR OTORHI, V43, P115, DOI 10.1016-S0165-5876(97)00159-6; Cohen Lance M., 1992, Ear Nose and Throat Journal, V71, P638; COWAN DL, 1982, L TURNERS DIS NOSE T, P129; GRANEY DO, 1999, CUMMINGS OTOLARYNGOL, P1327; HEFFNER DK, 1987, OTOLARYNG CLIN N AM, V20, P279; Huang SW, 2001, ANN ALLERG ASTHMA IM, V87, P350; JEANS WD, 1981, BRIT J RADIOL, V54, P117; KAMEL RH, 1990, J LARYNGOL OTOL, V104, P965, DOI 10.1017-S0022215100114495; MAURIZI M, 1984, INT J PEDIATR OTORHI, V8, P31, DOI 10.1016-S0165-5876(84)80023-3; MORRIS HL, 1990, ANN OTO RHINOL LARYN, V99, P432; Nguyen LHP, 2004, LARYNGOSCOPE, V114, P863, DOI 10.1097-00005537-200405000-00014; RICHTSMEIER WJ, 1987, OTOLARYNG CLIN N AM, V20, P219; TAKAHASHI H, 1989, AM J OTOLARYNG, V10, P208, DOI 10.1016-0196-0709(89)90065-3; THEOBALD WH, 1948, J LARYNGOL OTOL, V57, P677; Ungkanont K, 2004, INT J PEDIATR OTORHI, V68, P447, DOI 10.1016-i.ijporl.2003.11.016; WORMALD PJ, 1992, J LARYNGOL OTOL, V106, P342, DOI 10.1017-S0022215100119449; Yasan H, 2003, INT J PEDIATR OTORHI, V67, P1179, DOI 10.1016-S0165-5876(03)00222-234
Vocal technique in a group of Middle Eastern singers
No full textObjective: We aimed to report on the vocal technique in a group of Middle Eastern singers. Subjects and Method: A total of 78 Middle Eastern singers were assessed. Demographic data included age, gender, training status and number of years of singing. All singers had laryngeal videoendostroboscopy. Description and grading of posture, tension, type of breathing, type of phonation, resonance and tone quality are reported. Proportions and means (± SD) were used to describe the sample for categorical and continuous variables respectively. Associations between endostroboscopy and voice technique were determined by χ2 or Fisher's exact test. Results:There were 43 males and 35 females with an age ranging between 16 and 32 years and a mean of 23 ± 4 years. Of these, 88.5percent were nontrained singers and 50percent had more than 3 years of singing experience. Around 80percent of Middle Eastern singers rely on either thoracic or clavicular breathing. Posture was average in 68percent and moderate tension was present in 63percent of the cases. Two thirds had a bright voice, 61percent were hypernasal and almost 46percent had a strained phonation. There was a significant correlation between posture and tension. Conclusion: Middle Eastern singing relies more on thoracic breathing and is characterized by tension. Copyright © 2008 S.

Vocal symptoms in women undergoing in vitro fertilization
No full textObjective: The aim of this study was to investigate changes in vocal symptoms in relation to estrogen level in women undergoing in vitro fertilization. Materials and methods: A total of 31 women were enrolled in this study. The following vocal symptoms were investigated: vocal tiring or fatigue, vocal straining, throat clearing, lump sensation, hoarseness, and aphonia (or loss of voice). The severity of these symptoms was graded from 0 to 4, where 0 means absence of the symptom and 3 means severe symptom presence. The frequency of these symptoms was evaluated in the first visit at presentation; second visit, 4 to 5 days after ovarian stimulation; and third visit, 8 to 10 days after stimulation. In the second and third visits, the estradiol levels were measured. Results: The mean age was 32.33 ± 4.80 years. Ten of the 31 patients had at least 1 vocal symptom. The most common vocal symptom in all 3 visits was throat clearing, with an incidence of 22.6percent in the first and second visits and 19.4percent in the third visit. This was followed by vocal fatigue or tiring and lump sensation, with an incidence of 9.68percent for both. The incidence of all the vocal symptoms as well as their severity did not change throughout the visits, except for throat clearing, which has decreased in the third visit but not significantly (22.6percent vs 19.4percent, P = 1). Subjects with vocal symptoms had lower estradiol level compared with those with no vocal symptoms; however, the difference was not statistically significant (P =.108 and.267, respectively). Conclusion: Subjects undergoing in vitro fertilization do not experience changes in their vocal symptoms when present, except for throat clearing. However, those with vocal symptoms have lower levels of estradiol compared with those with no vocal symptoms. © 2012 Elsevier Inc.
