Total uterine artery blood volume flow rate in nulliparous women is associated with birth weight and gestational age at delivery.

OBJECTIVES: To investigate the relationship between total uterine artery blood volume flow rate (TVFR) and birth weight and gestational age at delivery, and to establish normal ranges of TVFR throughout pregnancy. METHODS: This was a prospective cohort study of 334 nulliparous women booking antenatal care at University College London Hospital between August 2008 and September 2009. Women underwent a transabdominal ultrasound examination of uterine arteries for measurement of TVFR at 12, 20 and 24 weeks' gestation. Pregnancy outcomes were recorded and linear regression was used to study the relationship between TVFR and gestational age at delivery and birth weight. RESULTS: A total of 551 ultrasound scans were performed. There was a significant, positive correlation between TVFR at 11-13 weeks (TVFR1) and at 22-26 weeks (TVFR3) and birth weight. For every 100-mL/min increase in TVFR1 and TVFR3, there was an increase in birth weight of 45 g and 27 g, respectively. There was also a positive association between TVFR1 and gestational age at delivery, with a 1.4-day increase in gestational age for every 100-mL/min increase of TVFR1. CONCLUSION: Ultrasound measurement of TVFR in the first trimester is significantly associated with both birth weight and gestational age at delivery. Copyright © 2016 ISUOG.

Should a detailed ultrasound examination of the complete urinary tract be routinely performed in women with suspected pelvic endometriosis?

STUDY QUESTION: Is there any benefit to including the routine examination by ultrasound of the bladder, ureters and kidneys of women with endometriosis? SUMMARY ANSWER: The benefit of examination of the complete urinary tract of women with suspected endometriosis is that ureteric endometriosis, with or without hydronephrosis, can be detected which facilitates early intervention to prevent nephropathy. WHAT IS ALREADY KNOWN: Women with endometriosis can get ureteric obstruction but there is no clear consensus on the correct diagnostic technique. Ultrasound is accurate at detecting women with bladder endometriosis but ureteric involvement has not been assessed previously. STUDY DESIGN, SIZE, DURATION: This was a prospective observational study, conducted at a teaching hospital over a period of 14 months. A total of 848 women presenting with chronic pelvic pain were included into the study. PARTICIPANTS/MATERIALS, SETTING, METHODS: All women with chronic pelvic pain underwent a detailed transvaginal and transabdominal pelvic ultrasound examination to investigate possible causes of their symptoms. This included a systematic assessment of the urinary bladder, pelvic sections of the ureters and kidneys. The ultrasound findings were compared with findings at surgery and the results of targeted urological imaging and interventions. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 848 women presenting with chronic pelvic pain were included into the study. 28/848 women (3.3% 95% CI 2.1-4.5) had evidence of urinary tract abnormalities on initial ultrasound scan. Among these 17/848 (2.0% 95% CI 1.06-2.94) had evidence of urinary tract endometriosis, whilst 11/848 (1.3% 95% CI 0.54-2.06) women had other urinary tract abnormalities. Among women with urinary tract endometriosis 11/17 (65%) had evidence of ureteric involvement, 3/17 (18%) had both ureteric and bladder disease and 3/17 (18%) had bladder disease only. 12/17 (59%) women with urinary tract endometriosis also had evidence of hydronephrosis. The diagnosis of ureteral endometriosis had a sensitivity of 12/13 (92%) (95% CI 63.9-99.8), specificity 151/151 100% (95% CI 97.6-100), PPV 100% (95% CI 73.5-100), NPV 99.3% (95% CI 96.3-99.9%) LR- 0.08 (95% CI 0.01-0.39). LIMITATIONS, REASONS FOR CAUTION: The routine examination of the complete urinary tract including the distal ureters is a novel technique that should be evaluated in different populations. WIDER IMPLICATIONS OF THE FINDINGS: Ultrasound is an accurate test to diagnose urinary tract involvement in women with suspected pelvic endometriosis and examination of the complete urinary tract should become an integral part of ultrasound assessment of women with suspected endometriosis.

Prevalence of pelvic adhesions on ultrasound examination in women with a history of Cesarean section.

OBJECTIVES: To investigate the prevalence and location of pelvic adhesions in women with a history of Cesarean section and to identify risk factors for their formation and symptoms associated with their presence. METHODS: This was a prospective observational study of women in whom one or more Cesarean sections had been performed > 12 months previously and who attended for a gynecological ultrasound examination. In all women, both transvaginal and transabdominal scans were performed in order to identify the presence of pelvic adhesions. Medical and surgical history was recorded and a structured questionnaire was used to enquire about any history of pelvic pain and urinary symptoms. RESULTS: A total of 308 women were recruited into the study. On ultrasound examination, 139 (45.1% (95% CI, 39.7-50.7%)) women showed evidence of adhesions within the pelvis. Adhesions in the vesicouterine pouch were the most common and were found in a total of 79 (25.6% (95% CI, 20.7-30.5%)) women. In women with a history of no surgery other than Cesarean section(s) (n = 220), an increasing number of Cesarean sections (odds ratio (OR) 3.4 (95% CI, 2.1-5.5)) and a postoperative wound infection (OR 11.7 (95% CI, 3.5-39.5)) increased the likelihood of adhesions developing in the anterior pelvic compartment. There was a significant association between the presence of anterior compartment adhesions and chronic pelvic pain. Multivariable logistic regression analysis identified anterior abdominal wall adhesions (OR 2.4 (95% CI, 1.0-5.9)) and any adhesions present on ultrasound scan (OR 2.6 (95% CI, 1.2-5.7)) as independent predictors of chronic pelvic pain. CONCLUSIONS: Pelvic adhesions are present in more than a third of women with a history of Cesarean section and they are associated with chronic pelvic pain.

Coping with an altered mouth and perceived supportive care needs following head and neck cancer treatment.

PURPOSE: Oral health is essential to general health and well-being and is severely impacted by head and neck cancer (HNC) and its treatment. This study aimed to describe how people who have been treated for HNC cope with altered oral health and function and to identify their supportive care needs. METHODS: A qualitative, descriptive approach was used. Data was collected from individual interviews with six participants 6 months after treatment. Data analysis was performed by qualitative content analysis involving inductive and directed approaches. Directed content analysis was guided by the Stress, Appraisal and Coping Model. RESULTS: Three themes describing changed oral health were identified from the data: dimensions of eating, maintaining oral health after treatment and adapting to the chronic side effects of treatment. A strong use of problem-focussed coping was described, in addition to the importance of peer support in adapting to the psychosocial outcomes of treatment. Support needs identified related to increased access to specialist dental oncology services post treatment, information needs and a need for more psychological support. CONCLUSION: The study findings describe the experience of a sample of people who have received treatment for HNC. Due to a demographically homogenous sample and the strong use of positive coping strategies, the results presented may not describe the experience of the wider HNC population; however, these results provide insight into factors that may influence positive coping.

Is adenomyosis associated with menorrhagia?

STUDY QUESTION: Is the presence of adenomyosis associated with menorrhagia? SUMMARY ANSWER: There was no significant association between adenomyosis and menorrhagia, but there was a significant positive correlation between the severity of adenomyosis on ultrasound and the amount of menstrual loss estimated using pictorial blood loss assessment charts. WHAT IS KNOWN ALREADY: There is no consensus in the literature with regards to the association between adenomyosis and menorrhagia. Previous studies have been limited to retrospective studies of highly selected populations which mainly included women who underwent hysterectomy. There are no large prospective studies evaluating the association between adenomyosis and menorrhagia, either in the general population of women or in a general gynaecology clinic setting. STUDY DESIGN, SIZE, DURATION: This was a prospective observational study set in the general gynaecology clinic of a university teaching hospital between January 2009 and January 2010. PARTICIPANTS/MATERIALS, SETTING, METHODS: There were 714 consecutive premenopausal women who attended the clinic and underwent structured clinical and transvaginal ultrasound examination in accordance with the study protocol. Morphological features of adenomyosis were systematically recorded on ultrasound scan. Menorrhagia was determined subjectively by direct questioning and objectively by completion of pictorial blood loss analysis charts. MAIN RESULTS AND THE ROLE OF CHANCE: A diagnosis of adenomyosis was made in 157/714 women [22.0% (95% CI: 19.1-25.2%)]. Multivariable analysis showed significant associations between submucous fibroids [OR 5.60 (95% CI: 2.69-11.6)], any fibroids [OR 1.53 (95% CI: 0.91-2.58)] and endometrial polyps [OR 2.81 (95% CI: 1.15-11.7)] and menorrhagia. There were also significant associations between increasing gravidity and BMI and menorrhagia (P < 0.01). There was no significant association between adenomyosis and menorrhagia in the study population, when adenomyosis was assessed as a binary outcome. When severity of adenomyosis was assessed by counting the number of morphological features of adenomyosis in each woman, we found a significant 22% increase in menstrual loss for each additional feature of adenomyosis [OR 1.21 (95% CI: 1.04-1.40)]. LIMITATIONS, REASONS FOR CAUTION: A classification of severity of adenomyosis based on the number of ultrasound features present is a novel concept that should be prospectively evaluated in different populations. WIDER IMPLICATIONS OF THE FINDINGS: A better understanding of the relationship between adenomyosis and menorrhagia can help improve counselling of women regarding the significance of this common condition and facilitate future studies assessing the effectiveness of different conservative treatments protocols. STUDY FUNDING/COMPETING INTEREST(S): The authors have no competing interests. The study was not supported by an external grant.

Implications of the composite free flap harvest site on quality of life after head and neck surgery: a prospective series.

Quality of life (QOL) has become a primary determinant of the treatment outcome. There is a poor evidence base regarding the QOL implications of free flap harvest from the various different osseous composite donor sites. This prospective study assessed the impact of free flap harvest on QOL and compared QOL morbidity between fibula, scapula, and iliac crest (deep circumflex iliac artery; DCIA) donor sites in head and neck reconstructive surgery. This was a single-site prospective cohort clinical research study. Fifty-nine patients were recruited between 2017 and 2021; 30 underwent fibula flap reconstructive surgery, 17 scapula flap, and 12 DCIA flap. The patients were assessed using the University of Washington Quality of Life Questionnaire version 4 (UW-QOL v4) preoperatively and again at >12 months postoperatively. The results showed no significant change in the mean global QOL score postoperatively when compared to the preoperative baseline in any of the donor site groups. However, the mean postoperative scores for the appearance domain were significantly lower than the preoperative scores in all of the donor site groups. In addition, fibula flap patients had significantly reduced physical activity and recreation QOL domain scores postoperatively when compared to the preoperative scores.

Diagnosis of uterine vein thrombosis on transvaginal ultrasound.

Deep venous thrombosis (DVT) is a potentially serious medical disorder, which may result in pulmonary embolism and death. Compression ultrasound is the investigation modality of choice for the diagnosis of DVT of the lower limb. Diagnosis of proximal thrombosis involving the pelvic veins is difficult and is usually made only after the thrombus extends into the veins of the lower limb. We present six cases of incidental uterine vein thrombosis diagnosed by transvaginal ultrasound. Our aim is to describe the technique of the examination of pelvic veins and criteria that could be used to diagnose uterine vein thrombosis. We also highlight difficulties in the management of women diagnosed with asymptomatic uterine vein thrombi as there is little evidence to guide clinicians in choosing between different treatment options.

Visualization of ureters on standard gynecological transvaginal scan: a feasibility study.

OBJECTIVE: To investigate the feasibility of identifying pelvic segments of normal ureters and measuring their size on standard transvaginal ultrasound examination. METHODS: This was a prospective observational study from June to July 2012. All women in the study underwent a transvaginal ultrasound examination performed for various indications either by an expert or by an intermediate-level operator. A standardized assessment of the pelvic organs was performed, recording any congenital or acquired uterine pathology and ovarian abnormalities. Visualization of pelvic segments of both ureters was attempted in all cases. The success in finding the ureters, the time required to identify them and their dimensions at rest and while exhibiting peristalsis were all recorded. RESULTS: A total of 245 consecutive women were included in the study. In all women at least one ureter was successfully identified. Both ureters were seen in 227 women (92.7% (95% CI, 89.4-96.0%)). In 17 (6.9% (95% CI, 3.7-10.1%)) the left ureter was not seen and in one woman (0.4% (95% CI, 0.0-1.2%)) the right ureter could not be visualized (P < 0.001). There were no significant differences in the median time required to visualize the right and left ureters (9.0 (interquartile range (IQR), 6.0-14.0) s vs 8.0 (IQR, 6.0 -14.0) s, respectively; P = 0.9). The median diameter of the right ureter was 1.7 (IQR, 1.4-2.2) mm at rest and 2.9 (IQR, 2.4-3.6) mm during peristalsis. The median diameter of the left ureter was 1.9 (IQR, 1.6-2.3) mm at rest and 2.9 (IQR, 2.4-3.6) mm during peristalsis. CONCLUSION: Pelvic segments of normal ureters can be identified in most women on transvaginal ultrasound examination. Visualization of the ureters could be integrated into the routine pelvic ultrasound examination, particularly in women presenting with pelvic pain or in those with suspected pelvic endometriosis.

How common is adenomyosis? A prospective study of prevalence using transvaginal ultrasound in a gynaecology clinic.

STUDY QUESTION: What is the prevalence of adenomyosis in a population of women attending a general gynaecological clinic? SUMMARY ANSWER: Adenomyosis was present in 206 of 985 [20.9%; 95% confidence interval (CI): 18.5-23.6%] women included in the study. WHAT IS KNOWN ALREADY: Previous studies of occurrence of adenomyosis have been limited to women who underwent hysterectomy, which is likely to overestimate its prevalence compared with the general population of women. There are no large prospective studies on the prevalence of adenomyosis, either in the general population of women or in a general gynaecology clinic setting. STUDY DESIGN, SIZE, DURATION: This was a prospective observational study set in the general gynaecology clinic of a university teaching hospital between January 2009 and January 2010. PARTICIPANTS/MATERIALS, SETTING, METHODS: There were 985 consecutive women who attended the clinic and underwent structured clinical and transvaginal ultrasound examination in accordance with the study protocol. Morphological features of adenomyosis were systematically recorded with the ultrasound scan to determine its prevalence and factors which may affect its occurrence. MAIN RESULTS AND THE ROLE OF CHANCE: Adenomyosis was present in 206/985 [20.9% (95% CI: 18.5-23.6%)] women included in the study. Multivariate analysis showed that the prevalence of adenomyosis was significantly associated with women's age, gravidity and pelvic endometriosis (P< 0.001). In women who subsequently underwent hysterectomy, there was a good level of agreement between the ultrasound and histological diagnosis of adenomyosis [κ = 0.62 (P = 0.001), 95% CI (0.324, 0.912)]. LIMITATIONS, REASONS FOR CAUTION: Our estimate of prevalence of adenomyosis is likely to be higher than in the general population as we studied symptomatic women attending a gynaecology clinic. WIDER IMPLICATIONS OF THE FINDINGS: Better estimates of the prevalence of adenomyosis can improve our understanding of the burden of the disease, help to identify women at high risk of developing the condition and facilitate the development of preventative strategies and effective treatment. STUDY FUNDING/COMPETING INTEREST(S): The authors have no competing interests to declare. The study was not supported by an external grant.

Donor site morbidity of composite free flaps in head and neck surgery: a systematic review of the prospective literature.

Composite free flaps represent the cornerstone for the repair of osseous defects in the head and neck. For many patients, there are often multiple defect-suitable donor sites that may be utilised as part of the reconstructive process. Therefore, to optimise patient outcomes, an evidence-based approach to donor site selection is required to maximise quality of life and long-term functionality. A systematic review of the literature was conducted in accordance with PRISMA guidelines to evaluate the evidence for donor site selection based on minimising the associated donor site morbidity and optimising patient functionality postoperative. The fibula is associated with the greatest potential risk for wound healing complications. Fibula and scapula harvest has the potential to have a significant impact on physical performance. The iliac crest is most favourable in terms of aesthetic scar healing outcomes. Overall, however, the quality and quantity of evidence for all donor sites is limited. Each site is associated with specific complications and morbidity, of which the surgeon and patient must both be aware. Whilst a cross-sectional informed opinion of the likely advantages/disadvantages of one donor site over another can thus be made, there are few head-to-head studies available that directly compare donor sites.

How do Australians living with MS experience oral health and accessing dental care? A focus group study.

OBJECTIVES: The symptoms of multiple sclerosis (MS) can affect oral care and access to dental services, but there is limited literature describing the oral health and perceived oral healthcare needs of people with MS. This study aimed to explore the oral health experiences, oral health behaviours and barriers to accessing dental care perceived by people living with MS in Australia. METHODS: Six focus groups were held across two metropolitan areas (Brisbane, Queensland and Melbourne, Victoria) and one regional area (Toowoomba, Queensland). Focus group data were analysed using thematic analysis. RESULTS: Living with MS was a highly individual experience due to the range of symptoms that may be experienced. In addition to having different symptom experiences to others with MS, individual symptoms also differed on a daily basis as the disease relapsed and remitted. The physical expressions of MS directly and indirectly affected the oral health of participants. Additionally, oral health was affected by the side effects of medications and orofacial pain symptoms. Depending on the symptoms experienced by the individual, personal oral hygiene was affected and professional dental appointments were difficult. Participants also experienced structural barriers to accessing professional dental care including difficulty accessing transport to-and-from dental appointments, space limitations in the dental surgery and financial barriers to care. DISCUSSION: Dental care was perceived to be inflexible and was not tailored to individual experiences of MS, which contributed to perceptions of poor quality and appropriateness of care. It is important for dental professionals to offer tailored and individualized dental care when treating people with MS. Our findings suggest that there needs to be greater interprofessional communication and referral to manage atypical dental pain symptoms. Oral health education for people with MS should include altered strategies to performing daily oral hygiene, the management of xerostomia and advice regarding low cariogenic diets suitable for dysphagia. Additionally, policy and strategies to improve the oral health of people with MS should focus on enhancing access through transport, reducing the cost of dental services to the individual and providing domiciliary oral health care.

Managing the oral side-effects of medications used to treat multiple sclerosis.

BACKGROUND: Many medications used to manage multiple sclerosis (MS) affect oral health. This review aimed to identify the oral side-effects of the current drugs recommended in Australia to treat MS and make dental practitioners aware of the range of symptoms. METHODS: The Australian Therapeutic Guidelines and the Australian Medicines Handbook were searched for medications used to treat MS. For each medication, the generic name, class, route of administration, dosage and drug company reported side-effects were extracted from the online Monthly Index of Medical Specialties (MIMs) database. Meyler's Side-effect of Drugs Encyclopaedia was used to identify any additional oral adverse reactions to medications used to treat MS. RESULTS: Fourteen drugs were identified for the treatment of MS progression and 13 drugs for the treatment of MS symptoms. For these medications, 18 oral side-effects were documented: xerostomia was the most common, followed by dysgeusia, dysphagia, mouth ulceration and sinusitis. Anticholinergic drugs caused xerostomia while immunosuppressants resulted in more infection-related side-effects. CONCLUSIONS: Dental practitioners should be aware of the range of symptoms likely to be reported by this population. Clinicians are encouraged to continue providing dental care for their patients who develop MS and refer complex cases to specialists.
