Review
BACKGROUND
Clinical practice frequently involves the practitioner touching patients' bodies in areas that are highly personal. If inappropriately performed, such intimate touch may result in much anxiety, confusion and misinterpretation. Examination of evidence is necessary to guide practice in this area to mitigate risks and foster optimal clinician-patient relations and care.
OBJECTIVES
The objective of this qualitative systematic review was to identify and synthesize findings on the perceptions, experiences and preferences of patients receiving a clinician's touch during intimate care and procedures INCLUSION CRITERIA TYPES OF PARTICIPANTS: The current review considered studies that included patients who had received a clinician's touch during intimate care and procedures.
PHENOMENA OF INTEREST
The current review considered qualitative studies that evaluated patients' perceptions, experiences and preferences of a clinician's touch during intimate care and procedures.
TYPES OF STUDIES
The current review considered studies that collected qualitative data and included studies using designs such as phenomenology, grounded theory, ethnography, action research, qualitative description, focus group methodology and feminist research. In the absence of research studies, other text such as opinion papers and reports were considered.
CONTEXT
The current review considered studies that included patients' perceptions, experiences and preferences of a clinician's touch during intimate care and procedures. Intimate care is likely to occur in any clinical setting where patients need assistance with personal care, where physical examinations occur, or in settings were gynecologic, genitourinary, lower intestinal, dermatologic, cardiac or other procedures involving highly personal areas of the body are performed.
SEARCH STRATEGY
A three-step search strategy was used to find published and unpublished studies in English from 1970 to 2016, searching various databases which included searches of reference lists of studies selected for appraisal.
METHODOLOGICAL QUALITY
Included studies were assessed for methodological quality independently by two reviewers using the Joanna Briggs Institute Qualitative Assessment and Review Instrument (JBI-QARI) prior to inclusion. Of the two studies included in the review, one did not discuss ontological and epistemological assumptions, and the other did not include the personal assumptions and role of the researcher.
DATA EXTRACTION
Data were extracted using the data extraction tool from the JBI-QARI. The data extracted included details about the phenomenon of interest, populations and study methods.
DATA SYNTHESIS
Qualitative findings were synthesized using JBI-QARI.
RESULTS
Two studies were included in this review. Seven findings were organized into three categories and one synthesized finding, "clinician respect". The finding suggests that clients prefer engaged and meaningful communication prior to and during an intimate touch encounter, expect autonomy over their bodies and desire shared decision making relative to how and by whom intimate touch is provided.
CONCLUSION
The synthesized finding from this review suggests that:More research is needed to explore the perceptions and preferences for intimate touch among diverse populations, generations, cultures and contexts. Particular exploration is needed for populations with additional vulnerabilities to misunderstandings, anxiety and abuse, such as pediatric and geriatric patients, and patients with physical, mental and cognitive impairments.

Spondylodiscitis can be a rare complication of gynecological surgery, typically of procedures involving the sacrum and the sacrospinous ligament. This report presents a case of spondylodiscitis arising after a laparoscopic sacrocolpopexy with a mesh. We also review the literature finding 52 cases of spondylodiscitis following sacrocolpopexy and (or) rectopexy with or without a mesh. We performed a comprehensive search from the electronic databases MEDLINE (Pubmed), Scopus, Web of Science, Embase, CINAHL, and Google Scholar from 1990 to February 2021 in order to identify case reports or case series reporting on spondylodiscitis after rectopexy or sacrocolpopexy. We identified 52 total postoperative spondylodiscitis. We examined the mean age of patients, the surgical history, the time from initial surgery to spondylodiscitis, the presenting symptoms, the diagnostic tools, the medical and surgical treatment, the type of mesh used, the surgical access, and the possible causes of spondylodiscitis. Diagnosis of spondylodiscitis may be challenging. From our review emerges that recurrent pelvic pain and lumbosciatalgia may be signals of lumbar spondylodiscitis. Magnetic resonance is the gold standard examination for spondylodiscitis. Surgical practice needs to be improved further in order to establish the best procedure to minimize the incidence of this complication. Awareness of symptoms, timely diagnosis, and treatment are fundamental to prevent irreversible complications.

Meta-Analysis Review
CONTEXT
Ovarian cancer is common and has significant morbidity and mortality, partly because it is often diagnosed at a late stage. This study sought to determine the accuracy of individual symptoms and combinations of symptoms for the diagnosis of ovarian cancer.
EVIDENCE ACQUISITION
MEDLINE was searched, identifying 2,492 abstracts, reviewing 71 articles in full, and ultimately identifying 17 studies published between 2001 and 2014 that met the inclusion criteria. Data were abstracted by two researchers, and quality was assessed using the QUADAS-2 criteria adapted to the study question. Bivariate random effects meta-analysis was used where possible, and heterogeneity and threshold effects were explored using receiver operating characteristic curves. Data were analyzed in 2015.
EVIDENCE SYNTHESIS
Most studies were at high risk of bias, primarily because of case-control design or differential verification bias. The highest positive likelihood ratios (LRs+) were found for presence of abdominal mass (LR+, 30.0); abdominal distension or increased girth (LR+, 16.0); abdominal or pelvic pain (LR+, 10.4); abdominal or pelvic bloating (LR+, 9.3); loss of appetite (LR+, 9.2); and a family history of ovarian cancer (LR+, 7.5). No symptoms were helpful at ruling out ovarian cancer when absent. The Ovarian Cancer Symptom Index was validated in five studies and (after excluding one outlier with different inclusion criteria) was 63% sensitive and 95% specific (LR+, 12.6; LR-, 0.39). Two other symptom scores had not been validated prospectively.
CONCLUSIONS
Several individual signs and symptoms significantly increase the likelihood of ovarian cancer when present. More work is needed to validate decision rules and develop new decision support tools integrating risk factors, symptoms, and possibly biomarkers to identify women at increased ovarian cancer risk.

Endometriosis-related pleural effusion (PE) is a relatively rare but treatable cause of bloody PE. The clinical characteristics and outcome of patients with endometriosis-related PE remain unknown. We present a case of endometriosis-related PE diagnosed on pleural fluid cytology. A systematic review of all endometriosis-related PE cases in literature was conducted to elucidate the clinical characteristics, explore the diagnostic yield of pathological examinations, and to summarize the outcomes of therapeutic approaches in this disease. A case of endometriosis-related PE diagnosed in study hospital was reported. PubMed, Web of Science, and EMBASE were searched for publications pertaining to cases of endometriosis-related PE using predefined search terms. This case and those identified from PubMed, Web of Science, and EMBASE were analyzed. A total of 67 patients were included. Catamential symptoms were presented in 30 (44.8%) patients. Dyspnea was presented in 50 patients (74.6%), followed by right chest/shoulder pain in 34 (50.7%) and cough in 18 (26.9%). 82.8% of the patients had concomitant pelvic endometriosis and 76.7% was infertile or nulliparous. The diagnostic yield of pleural fluid cytological examination, percutaneous pleural biopsy, and surgical biopsy was 9.0, 45.5, and 78.7%, respectively. The patients who received surgery-based therapy had a significantly longer time to relapse than those who received progestational agents or GnRH analogs alone ( = 0.025) or hysterectomy and bilateral salpingoophorectomy (HBSO) ( = 0.040). High clinical awareness of pleural endometriosis is essential in all female with hemorrhagic PE, especially in young females who have infertility and/or pelvic endometriosis. Plerual fluid cytology might be a simple minimally invasive and cost-effective modality in the diagnosis of endometriosis-related PE. Treatment is challenging due to high recurrence and the optimal management of endometriosis-related PE needs further evaluation. The combined approach by surgery and hormonal therapy may achieve the best relapse-free survival.

Review
BACKGROUND
Chronic abacterial prostatitis is a common disabling but enigmatic condition with a symptom complex of pelvic area pain and lower urinary tract symptoms. The scope of treatments recommended for chronic abacterial prostatitis is a testament to how little is known about what causes the condition and how to treat it. As a result, chronic abacterial prostatitis often causes physician frustration, patient confusion and dissatisfaction, variable thresholds for referral, and potentially inappropriate antibiotic use.
OBJECTIVES
Examine the evidence regarding the effectiveness of therapies for chronic abacterial prostatitis.
SEARCH STRATEGY
Studies were identified through a search of MEDLINE (1966-2000), the Cochrane Library, bibliographies of identified articles and reviews, and contact with an expert.
SELECTION CRITERIA
Studies were eligible if they: (1) are randomized controlled trials (RCTs) or controlled clinical trials (CCTs) (2) involve men with chronic abacterial prostatitis (3) control group receives placebo, sham intervention, active pharmacologic or device therapy for chronic abacterial prostatitis and (4) outcomes data are provided. Eligibility was assessed by at least two independent observers.
DATA COLLECTION AND ANALYSIS
Study information on patients, interventions, and outcomes was extracted independently by 2 reviewers. The main outcome was the efficacy of treatment for chronic abacterial prostatitis vs. control in improving urologic symptom scale scores or global report of urinary tract symptoms. Secondary outcomes included changes in the prostate examination, uroflowmetry, urodynamics, analysis of urine, expressed prostatic secretions and seminal fluid, and prostate ultrasonography.
MAIN RESULTS
The 15 treatment trials involved: medications used to treat benign prostatic hyperplasia (n=4 trials); anti-inflammatory medications (n=2 trials); antibiotics (n=1 trial); thermotherapy (n=5 trials); and miscellaneous medications (n=3 trials). The disparity between studies did not permit quantitative analysis. There were a total of 600 enrollees (age range 38-45). All but one of the trials were done outside the United States.
REVIEWER'S CONCLUSIONS
The treatment trials are few, weak methodologically, and involve small sample sizes. The routine use of antibiotics and alpha blockers for chronic abacterial prostatitis is not supported by the existing evidence. The small studies examining thermal therapy appear to demonstrate benefit of clinical significance and merit further evaluation. Additional treatment trials are required and they should report important patient characteristics (e.g., race), study design details and utilize clinically relevant and validated assessment measures.

The Clinical Journal of Pain 2005Sacroiliac joint dysfunction is believed to be a significant source of low back and posterior pelvic pain. (Review)
Review
UNLABELLED
Sacroiliac joint dysfunction is believed to be a significant source of low back and posterior pelvic pain.
METHODS
To assess the clinical presentation, diagnostic testing, and treatment options for sacroiliac joint dysfunction, a systematic literature review was performed using MEDLINE.
RESULTS
Presently, there are no widely accepted guidelines in the literature for the diagnosis and treatment of sacroiliac instability. Establishing management guidelines for this disorder has been complicated by the large spectrum of different etiologic factors, the variability of patient history and clinical symptoms, limited availability of objective testing, and incomplete understanding of the biomechanics of the sacroiliac joint.
CONCLUSIONS
A reliable examination technique to identify the sacroiliac joint as a source of low back pain seems to be pain relief following a radiologically guided injection of a local anaesthetic into the sacroiliac joint. Most patients respond to non-operative treatment. Patients who do not respond to non-operative treatment should be considered for operative sacroiliac joint stabilization.

Review
Positron emission tomography/computerised tomography imaging in detecting and managing recurrent cervical cancer: systematic review of evidence, elicitation of subjective probabilities and economic modelling.
BACKGROUND
Cancer of the uterine cervix is a common cause of mortality in women. After initial treatment women may be symptom free, but the cancer may recur within a few years. It is uncertain whether it is more clinically effective to survey asymptomatic women for signs of recurrence or to await symptoms or signs before using imaging.
OBJECTIVES
This project compared the diagnostic accuracy of imaging using positron emission tomography/computerised tomography (PET-CT) with that of imaging using CT or magnetic resonance imaging (MRI) alone and evaluated the cost-effectiveness of adding PET-CT as an adjunct to standard practice.
DATA SOURCES
Standard systematic review methods were used to obtain and evaluate relevant test accuracy and effectiveness studies. Databases searched included MEDLINE, EMBASE, Science Citation Index and The Cochrane Library. All databases were searched from inception to May 2010.
REVIEW METHODS
Study quality was assessed using appropriately modified Quality Assessment of Diagnostic Accuracy Studies (QUADAS) criteria. Included were any studies of PET-CT, MRI or CT compared with the reference standard of histopathological findings or clinical follow-up in symptomatic women suspected of having recurrent or persistent cervical cancer and in asymptomatic women a minimum of 3 months after completion of primary treatment. Subjective elicitation of expert opinion was used to supplement diagnostic information needed for the economic evaluation. The effectiveness of treatment with chemotherapy, radiotherapy, chemoradiotherapy, radical hysterectomy and pelvic exenteration was systematically reviewed. Meta-analysis was carried out in RevMan 5.1 (The Cochrane Collaboration, The Nordic Cochrane Centre, Copenhagen, Denmark) and Stata version 11 (StataCorp LP, College Station, Texas, USA). A Markov model was developed to compare the relative cost-effectiveness using TreeAge Pro software version 2011 (TreeAge Software Inc., Evanston, IL, USA).
RESULTS
For the diagnostic review, a total of 7524 citations were identified, of which 12 test accuracy studies were included in the review: six studies evaluated PET-CT, two evaluated MRI, three evaluated CT and one evaluated both MRI and CT. All studies were small and the majority evaluated imaging in women in whom recurrence was suspected on the basis of symptoms. The PET-CT studies evaluated local and distant recurrence and most used methods similar to current practice, whereas five of the six CT and MRI studies evaluated local recurrence only and not all employed currently used methods. Meta-analysis of PET-CT studies gave a sensitivity of 92.2% [95% confidence interval (CI) 85.1% to 96.0%] and a specificity of 88.1% (95% CI 77.9% to 93.9%). MRI sensitivities and specificities varied between 82% and 100% and between 78% and 100%, respectively, and CT sensitivities and specificities varied between 78% and 93% and between 0% and 95%, respectively. One small study directly compared PET-CT with older imaging methods and showed more true-positives and fewer false-negatives with PET-CT. The subjective elicitation from 21 clinical experts gave test accuracy results for asymptomatic and symptomatic women and the results for symptomatic women were similar to those from the published literature. Their combined opinions also suggested that the mean elicited increase in accuracy from the addition of PET-CT to MRI and/or CT was less than the elicited minimum important difference in accuracy required to justify the routine addition of PET-CT for the investigation of women after completion of primary treatment. For the effectiveness review, a total of 24,943 citations were identified, of which 62 studies were included (chemotherapy, 19 randomised controlled trials; radiotherapy or chemoradiotherapy, 16 case series; radical hysterectomy and pelvic exenteration, 27 case series). None provided the effectiveness of cisplatin monotherapy, the most commonly used chemotherapeutic agent in the NHS, compared with supportive care in a background of other treatment such as radiotherapy in recurrent and persistent cervical cancer. The model results showed that adding PET-CT to the current treatment strategy of clinical examination, MRI and/or CT scan was significantly more costly with only a minimal increase in effectiveness, with incremental cost-effectiveness ratios for all models being > £1M per quality-adjusted life-year (QALY) and the additional cost per additional case of recurrence being in the region of £600,000.
LIMITATIONS
There was considerable uncertainty in many of the parameters used because of a lack of good-quality evidence in recurrent or persistent cervical cancer. The evidence on diagnostic and therapeutic impact incorporated in the economic model was poor and there was little information on surveillance of asymptomatic women.
CONCLUSIONS
Given the current evidence available, the addition of PET-CT to standard practice was not found to be cost-effective in the diagnosis of recurrent or persistent cervical cancer. However, although probabilistic sensitivity analysis showed that the main conclusion about cost-ineffectiveness of PET-CT was firm given the range of assumptions made, should more reliable information become available on accuracy, therapeutic impact and effectiveness, and the cost of PET-CT reduce, this conclusion may need revision. Current guidelines recommending imaging for diagnosis using expensive methods such as PET-CT need to be reconsidered in the light of the above.

Journal of Ultrasonography Sep 2022The purpose of this study was to use ultrasonographic data to rule out and distinguish diseases that cause acute pelvic pain.
OBJECTIVE
The purpose of this study was to use ultrasonographic data to rule out and distinguish diseases that cause acute pelvic pain.
MATERIAL AND METHOD
The literature was reviewed using a systematic search of the databases Google Scholars and PubMed, as well as through hand searching. We looked through a total of 35 articles, but only 26 were selected after preliminary screening. Furthermore, 14 articles were left out because they required a membership, copyright clearance, or featured non-English references. There were a total of 12 articles included in the final revuew. Among all the study-related articles, only original research studies and one systematic review that sonographically explored the gynecological etiology of acute pelvic pain were selected.
RESULTS
Acute pelvic pain in women might be difficult to identify between gynecologic and non-gynecologic causes based solely on patient history and examination. Advanced imaging, like ultrasound, aids in determining the reason. Pelvic inflammatory disease can be difficult to diagnose, and clinicians should use a low threshold for starting presumptive treatment in order to avoid significant long-term effects such as infertility.
CONCLUSIONS
Pelvic pain can be acute, chronic or functional. Imaging investigations such as CT, ultrasonography, and MRI can assist in establishing a diagnosis. Particularly ultrasound scanning makes it possible to arrive at a diagnosis with a high degree of precision.

BACKGROUND
Vitamin D deficiency causes the bone hypomineralization disorder osteomalacia in humans and is associated with many non-skeletal disorders. We aim to estimate the global and regional prevalence of vitamin D deficiency in people aged 1 year or older from 2000 to 2022.
METHODS
We systematically searched Web of Science, PubMed (MEDLINE), Embase, Scopus, and Google databases on December 31, 2021, and updated them on August 20, 2022, without language and time restrictions. Meanwhile, we identified references of relevant system reviews and eligible articles and included the latest and unpublished data from the National Health and Nutrition Examination Survey (NHANES, 2015-2016 and 2017-2018) database. The studies investigating the prevalence of vitamin D deficiency in population-based studies were included. A standardized data extraction form was used to collect information from eligible studies. We used a random-effects meta-analysis to estimate the global and regional prevalence of vitamin D deficiency. We stratified meta-analyses by latitude, season, six WHO regions, the World Bank income groups, gender, and age groups. This study was registered with PROSPERO (CRD42021292586).
FINDINGS
Out of 67,340 records searched, 308 studies with 7,947,359 participants from 81 countries were eligible for this study, 202 (7,634,261 participants), 284 (1,475,339 participants), and 165 (561,978 participants) studies for the prevalence of serum 25(OH)D <30, <50, and <75 nmol/L, respectively. We found that globally, 15.7% (95% CrI 13.7-17.8), 47.9% (95% CrI 44.9-50.9), and 76·6% (95% CrI 74.0-79.1) of participants had serum 25-hydroxyvitamin D levels less than 30, 50, and 75 nmol/l, respectively; the prevalence slightly decreased from 2000-2010 to 2011-2022, but it was still at a high level; people living in high latitude areas had a higher prevalence; the prevalence in winter-spring was 1.7 (95% CrI 1.4-2.0) times that in summer-autumn; the Eastern Mediterranean region and Lower-middle-income countries had a higher prevalence; females were vulnerable to vitamin D deficiency; gender, sampling frame, detection assays, sampling region, time of data collection, season, and other factors contributed to heterogeneity between the included studies.
INTERPRETATION
Globally, vitamin D deficiency remained prevalent from 2000 to 2022. The high prevalence of vitamin D deficiency would increase the global burden of disease. Therefore, governments, policymakers, health workers, and individuals should attach importance to the high prevalence of vitamin D deficiency and take its prevention as a public health priority.

Meta-Analysis
BACKGROUND
The combination of shear wave elastography (SWE) and gray-scale ultrasound is widely used in the measurement of female pelvic floor muscle. However, the value of gray-scale ultrasound combined with SWE in the evaluation of primipara pregnancy and delivery is still controversial.
METHODS
Using the PubMed, Web of Science, Spring and Science Direct databases, clinical studies on gray-scale ultrasound combined with SWE on the diagnosis of primiparous pregnancy and childbirth published from January 2010 to December 2020 were searched. The RevMan5.3 software was used to conduct a meta-analysis of the indicators of gray-scale ultrasound combined with SWE for primiparas and non-primiparas, including: age, body mass index (BMI), gestational age at examination, gestational age at delivery, fetal weight, cervical length, shear wave velocity (SWV), front lip SWV, back lip SWV, Young's modulus and SWE index. Heterogeneity of the assessment results was tested using Cochran's chi-square.
RESULTS
A total of 13 articles were included. Age, BMI before delivery, gestational age (when gray-scale ultrasound was combined with SWE examination), gestational age at delivery, neonatal weight, cervical depth, SWV of placental margin, SWV of anterior lip, SWV of posterior lip and Young's modulus of the study group were significantly different from those of the control group. The elastic modulus of the perineal body and the SWE of the anterior lip of the study group were significantly higher than those of the control group [mean difference (MD) =8.11, 4.39, 95% confidence interval (CI): 3.90-12.31, 0.94-7.83; Z=3.78, 2.49, P=0.0002, 0.01]. The SWE of the posterior lip in the study group was significantly lower than that in the control group (MD =-4.34, 95% CI: -7.23 to 1.44; Z=2.93, P=0.003).
DISCUSSION
The number of cases in the control group in the included articles was significantly more than that in the observation group, and there were fewer descriptions of gray-scale ultrasound combined with SWE indicators in the included articles. There may be a certain degree of bias for indicators without obvious heterogeneity, and further analysis was required through a large number of clinical verifications. However, this study can provide certain reference values for the diagnosis of primipara pregnancy.
