Patients commonly present in primary care with symptoms for which no physical pathology can be found. This study is a review of published research on medically unexplained symptoms (MUPS) in primary care. A literature review and qualitative comparison of information was carried out. Four questions were addressed: what is the prevalence of MUPS; to what extent do MUPS overlap with psychiatric disorder; which psychological processes are important in patients with MUPS; and what interventions are beneficial? Neither somatised mental distress nor somatisation disorders, based on symptom counts, adequately account for most patients seen with MUPS. There is substantial overlap between different symptoms and syndromes, suggesting they have much in common. Patients with MUPS may best be viewed as having complex adaptive systems in which cognitive and physiological processes interact with each other and with their environment. Cognitive behavioural therapy and antidepressant drugs are both e...
Medically Unexplained Symptoms and Somatoform Disorders: Diagnostic Challenges to Psychiatrists
Journal of the Chinese Medical Association, 2009
Background: Clinical limitations of the criteria of somatoform disorders (SDs) have been criticized. However, little objective evidence supports this notion. We aimed to examine the prevalence of SDs in a population with medically unexplained symptoms (MUS), which was expected to have higher probabilities meriting such diagnoses, and to evaluate factors that may influence the clinical judgment of psychiatrists. Methods: Data of subjects with MUS (n = 101, 9.5%) as their chief consulting problems, of 1,068 consecutive ethnic Chinese adult medical inpatients referred for consultation-liaison psychiatry services, were reviewed. Psychiatric diagnoses including SDs and clinical variables were collected. Those with SDs were followed-up 1 year later, and structured interviews were applied. Results: Patients with MUS had a high level of psychiatric comorbidity, especially depression (35.6%) and anxiety disorder (29.7%), rather than SDs (9.9%). Most diagnosed with SDs suffered from persistent MUS at the 1-year follow-up. Pain was the most common presentation of MUS. Most of the subjects diagnosed with SDs were female and younger, with multiple painful sites at presentation, no past psychiatric diagnosis and no comorbid organic diagnoses. The diagnosis of SDs was seldom given in those with simultaneous MUS and mood symptoms. Conclusion: A significant proportion (9.5%) of patients in psychiatric consultation suffered from MUS, and most were comorbid with depression and anxiety. The identification of SDs was made in only 9.9%. Because MUS are associated with a high rate of mental comorbidities, psychiatric consultations while facing such clinical conditions are encouraged.

Somatoform disorders and medically unexplained symptoms in primary care
Deutsches Ärzteblatt international, 2015
The literature contains variable figures on the prevalence of somatoform disorders and medically unexplained symptoms in primary care. The pertinent literature up to July 2014 was retrieved by a systematic search in the PubMed/MEDLINE, PsychInfo, Scopus, and Cochrane databases. The methodological quality and heterogeneity (I2) of the retrieved trials were analyzed. The prevalence rates of medically unexplained symptoms, somatoform disorders, and their subcategories were estimated, along with corresponding 95% confidence intervals (CI), with the aid of random-effects modeling. From a total of 992 identified publications, 32 studies from 24 countries involving a total of 70 085 patients (age range, 15-95 years) were selected for further analysis. All had been carried out between 1990 and 2012. The primary studies were more heterogeneous overall; point prevalences for the strict diagnosis of a somatization disorder ranged from 0.8% (95% CI 0.3-1.4%, I2 = 86%) to 5.9% (95% CI 2.4-9.4%, ...

Background: To investigate the validity and stability of a Portuguese version for the Screening for Somatoform Symptoms-2 (SOMS-2) in primary care (PC) settings. Methods: An adapted version of the SOMS-2 was filled in by persons attending a PC unit. All medically unexplained symptoms were further ascertained in a clinical interview and by contacting the patient's physicians and examining medical records, attaining a final clinical symptom evaluation (FCSE). An interview yielded the diagnosis of Clinical Somatization (CS) and the diagnosis of current depressive and anxiety disorders. Results: From the eligible subjects, 167 agreed to participate and 34.1% of them were diagnosed with somatization. The correlation between the number of self-reported and FCSE symptoms was 0.63. After excluding symptoms with low frequency, low discriminative power and not correlated with the overall scale, 29 were retained in the final version. A cut-off of 4 symptoms gave a sensitivity of 86.0% and a specificity of 95.5% on the FCSE and 56.1% and 93.6% at selfreport. Stability in the number of symptoms after 6 months was good (k = 0.57).

Background: Individuals with somatization may be the most difficult to manage because of the diverse and frequent complaints across many organ systems. They often use impressionistic language to describe circumstantial symptoms which though bizarre, may resemble genuine diseases. The disorder is best understood in the context "illness" behaviour, masking underlying mental disorder, manifesting solely as somatic symptoms or with comorbidity. Objective: To evaluate somatization symptoms and explore its comorbidity in order to improve the management of these patients. Methods: A cross-sectional survey of 60 somatizing patients who were part of a case-control study, selected by consecutive sampling of 2668 patients who presented at the Family Medicine Clinic of University College Hospital Ibadan, Nigeria between May-August 2009. Data was collected using the ICPC-2, WHO-Screener and Diagnostic Schedule and analysed with SPSS 16. Results: There were at least 5 symptoms of somatization in 93.3% of the patients who were mostly females. Majority had crawling sensation, "headache", unexplained limb ache, pounding heart, lump in the throat and insomnia. The mean age at onset was 35yrs with 90% having recurrence of at least 10yrs.Approximately 54% had comorbidity with cardiovascular disease being the most prevalent. Conclusions: The study revealed that somatization is not a specific disease but one with a spectrum of expression. This supports proposition that features for the diagnosis of somatization could be presence of three or more vague symptoms and a chronic course lasting over two years. It is important to be conversant with pattern of symptoms and possible comorbidity for effective management of these patients.
Somatising disorders: untangling the pathology
Australian family physician, 2007
Somatising disorders are a common, complex and disabling cluster of disorders. Research suggests that general practitioners find this group of patients challenging. The disorders are complicated by the fact that doctors play a role in both their aetiology and maintenance. The interaction between the illness worry of the patient and the disease worry of the doctor can lead to escalating disability and the risk of iatrogenic disease. In this article, common conceptual frameworks for somatising disorders are discussed and a framework for managing these complex disorders is presented. Patients with somatising disorders need to establish a positive therapeutic relationship with their doctor that encourages open and honest discussion of their illness. General practitioners need to strike a balance between empathy for the patient's suffering and collusion in their disease worry. Excessive intervention and investigation should be avoided. This may require considerable professional suppo...
Medically Unexplained Physical Symptoms in Medical Practice: A Psychiatric Perspective
Environmental Health Perspectives, 2002
Clusters of medically unexplained physical symptoms have been referred to in the literature by many different labels, including somatization, symptom-based conditions, and functional somatic syndromes, among many others. The traditional medical perspective has been to classify and study these symptoms and functional syndromes separately. In psychiatry, current taxonomies (Diagnostic and Statistical Manual of Mental Disorder, 4th edition, and The International Statistical Classification of Diseases and Related Health Problems, 10th revision) classify these syndromes together under the rubric of somatoform disorders. In this article we approach medically unexplained physical symptoms from a psychiatric perspective and discuss the common features that unite multiple unexplained symptoms or functional somatic syndromes as a class. Included in this article is a discussion of nosological issues, clinical assessment, how these syndromes are viewed within the various medical specialties, and clinical management and treatment.
