Hysterical conversion paralysis in an adolescent boy with lumbar spondylolysis

["Somatic symptom disorders" in adolescence. A systematic review of the recent literature]

OBJECTIVES

Body expression of mental disorders is common in adolescence. Only two literature reviews over the last five years have been identified about somatoform disorders in children., The present article provides a systematic review of articles in English, which concern "Somatic Symptom and Related Disorders" according to the DSM-5 (Diagnostic and Statistical Manual - 5th Edition) among adolescents.

METHODS

The article search was made on Medline, Psychinfo, Google Scholar, BiomedCentral, Central and tripdatabase (for grey literature) according to PRISMA criteria and with the items "somatoform disorders" or "somatic symptom disorders". An age filter was applied for "adolescents", and a selection was done from the last five years. All articles concerning adolescents (often associated with children) were initially included, except for articles concerning eating disorders, dysmorphic disorders or adult population. Comments, editorials, opinion or descriptive articles were also excluded. The authors then carried out an analysis of the main topics, themes and questions covered in the selected publications and presented a descriptive synthesis.

RESULTS

A total of seventy-seven publications were included in the analysis, from three hundred and seventy-two publications. First, the terms used to refer to these "somatic symptom disorders" were varied, such as "somatization", "somatic complaints/symptoms", "functional disorder", "unexplained symptoms" and "somatoform disorders". Then, studies related just to adolescents were limited: most of studies included children and adolescents in their methodologies; and some of them questioned somatic symptoms from a developmental perspective. Case reports were the most represented articles among all medical specialties, with clinical descriptions about "functional neurological symptom disorder", "factitious disorder" and "somatic symptom disorder" with a medical disease, among children and adolescents. We sometimes observed a controversial borderline between psychological and somatic disorders. Various explanatory models appeared, especially the trauma path; familial and social environment was also pointed out, with a possible peer group effect; neurocognitive theories were finally described. The literature highlights the effectiveness of psychosocial therapies (especially the cognitive-behavioral therapy) and the importance of multidisciplinary management. Finally, a few studies with a qualitative methodology are represented.

CONCLUSIONS

Only nine articles included "somatic symptom disorder" in their titles, despite a terminology valued by many authors (compared to "somatoform disorders" from the DSM-IV). The heterogeneity of terminologies, case reports and explanatory models witness a lack of connexions between medical specialties. This could explain in part the wandering of adolescents and their families in the health care system. It could also contribute to the delay before diagnosis, especially when neurological symptoms exist, and a late referral for psychiatric consultation. Further studies are needed to understand difficulties to use a clinical pathway among medical specialties, when the benefit of amultidisciplinary approach seems to be unanimous.

Upper extremity conversion disorder in children

BACKGROUND

Conversion disorder in children presents a challenge to orthopedic surgeons. The condition is frequently associated with unnecessary diagnostic tests, treatments, and cost. The purpose of this study was to report a series of children with upper extremity conversion disorder to raise awareness for this uncommon condition and to assist with its diagnosis and management.

METHODS

A retrospective review was conducted of 4 pediatric patients with upper extremity conversion disorder at a tertiary pediatric hospital from 2015 to 2017. Medical records were reviewed for patient demographics, including psychiatric history, clinical findings, diagnostic studies, treatment, and cost of care.

RESULTS

Patients presented with upper extremity muscle stiffness, unremitting dysmorphic muscle spasms, weakness, pain, very limited shoulder range of motion, and complaints of recurrent shoulder dislocations. All patients had been evaluated by multiple specialists and had an extensive prior diagnostic workup that was inconclusive. Two patients had a history of prior psychiatric illness and suicidal ideation, and all patients expressed despair and depression. All patients had normal physical examination findings under anesthesia. Two patients with muscle stiffness were treated with botulism injections and improved their shoulder range of motion. The average total charge for care since presentation was $42,729.

CONCLUSIONS

Conversion disorder should be considered in patients with an extensive prior diagnostic workup, deficits inconsistent with anatomic patterns or imaging findings, and a history of prior psychiatric illness. Examination under anesthesia is a successful diagnostic approach in children with suspected conversion disorder.
