Sensory modulation dysfunction is associated with Complex Regional Pain Syndrome

OBJECTIVE

Complex Regional Pain Syndrome (CRPS), a chronic pain condition, develops mainly after limb trauma and severely inhibits function. While early diagnosis is essential, factors for CRPS onset are elusive. Therefore, identifying those at risk is crucial. Sensory modulation dysfunction (SMD), affects the capacity to regulate responses to sensory input in a graded and adaptive manner and was found associated with hyperalgesia in otherwise healthy individuals, suggestive of altered pain processing.

AIM

To test SMD as a potential risk factor for CRPS.

METHODS

In this cross-sectional study, forty-four individuals with CRPS (29.9±11 years, 27 men) and 204 healthy controls (27.4±3.7 years, 105 men) completed the Sensory Responsiveness Questionnaire-Intensity Scale (SRQ-IS). A physician conducted the CRPS Severity Score (CSS), testing individuals with CRPS.

RESULTS

Thirty-four percent of the individuals with CRPS and twelve percent of the healthy individuals were identified to have SMD (χ2 (1) = 11.95; p<0.001). Logistic regression modeling revealed that the risk of CRPS is 2.68 and 8.21 times higher in individuals with sensory over- and sensory under-responsiveness, respectively, compared to non-SMD individuals (p = 0.03 and p = 0.01, respectively).

CONCLUSIONS

SMD, particularly sensory under-responsiveness, might serve as a potential risk factor for CRPS and therefore screening for SMD is recommended. This study provides the risk index probability clinical tool a simple evaluation to be applied by clinicians in order to identify those at risk for CRPS immediately after injury. Further research is needed.

Patients with spinal cord damage due to uncertain/unknown etiology: the CP phenomenon (confusion and perplexity). Case reports

Usually, most of the clients who are referred to departments of rehabilitation medicine, bear firm and sound diagnoses. We describe herewith 10 patients who developed spinal cord pathologies due to unknown or uncertain etiologies. We would like to share our thoughts with the readers.

[Medical rehabilitation of patients with osteogenesis imperfecta (OI) and additional newly acquired disabilities]

Adults with Osteogenesis Imperfecta (OI) are rarely referred to facilities of general rehabilitation medicine. Recently, two OI patients were admitted to our department because of additional neurological disabilities: stroke and spinal cord injury. In these circumstances, the hospitalization course has different characteristics.

Outcomes in patients admitted for rehabilitation with spinal neurological lesions following intervertebral disc herniation

BACKGROUND

Little information is available about the survival, neurological recovery, and length of stay in hospital for rehabilitation (LOS) of patients with spinal neurological deficit following disc herniation (DH).

STUDY DESIGN

Retrospective cohort study.

OBJECTIVE

To report on outcomes and factors affecting these.

SETTING

The Spinal Research Laboratory, Loewenstein Rehabilitation Hospital, Israel.

SUBJECTS

A total of 158 patients with DH spinal neurological lesions (DHSNL).

METHOD

Data were collected retrospectively. Survival was assessed using the Kaplan-Meier method; relative mortality risk by the Cox proportional hazard model. Neurological recovery was evaluated by calculating the change in Frankel grades, and factors that affect it were assessed by logistic regression. LOS associations were analyzed with ANOVA.

RESULTS

The median age at lesion onset was 48 years, and the median survival 29 years. Age and gender had a significant effect on survival, but not so lesion severity, level, or decade of onset. Of the 69 patients who had Frankel grades A, B, or C on admission, 72% achieved useful recovery to grades D or E. The severity and level of the spinal neurological lesion (SNL) had a significant effect on recovery. The mean LOS was 87 days; it was significantly affected by lesion severity and level and by the decade of admission to rehabilitation, and decreased with time.

CONCLUSIONS

Patients with DHSNL who were admitted for rehabilitation have favorable survival and recovery rates compared with previously studied patients with other types of SNL. Their LOS is probably a function of medical requirements, but is decreasing with time.

[Relief of chronic cervical pain after selective blockade of zygapophyseal joint]

Osteoarthrosis of the zygapophyseal joint (Z-joint) is a potential cause of chronic cervical pain. The diagnosis of thirty patients, with pain of more than 12 months duration and with no history of trauma, was confirmed with intra-articular fluoroscopy-guided infiltration of anesthetic. The patients were subsequently treated with intra-articular corticosteroids (Depo-Medrol 40 mg). Visual Analogue Scale was used for evaluation purposes. The mean time for relapse of 50 percent of the pre-injection level of pain was 12.47 +/- 1.89 weeks, significantly longer than 3 days as reported in patients similarly treated following whiplash neck injury. At this point selective blockade of Z-joints may be offered as an adjunct for diagnostic and therapeutic purposes for patients with chronic neck pain due to facet osteoarthrosis in the ambulatory setup.

[Our experience with the medical rehabilitation of homeless-disabled people]

During the last two years, 11 homeless-disabled people were treated at our rehabilitation ward. All of the patients were Jewish, six were new immigrants from Russia, their age ranged between 34 to 60 years, most of these patients had completed at least high school education, and all had managed to have a "normal" social-working life until the crisis which led them to the street. Six became alcoholics and one was a narcotic-drug user. None of these patients suffered from malnutrition or mental disorder, and after the rehabilitation process was over, they became independent, performing the activities of daily living. Most of them decided to return to their previous street--living place, despite their disabilities. This new combination of relatively young disabled-homeless people at our rehabilitation facility demands novel and different rehabilitation approaches.

Incidence and perinatal outcome of multiple pregnancies after intracytoplasmic sperm injection compared to standard in vitro fertilization

PURPOSE

Our purpose was to assess the incidence of multiple pregnancies and their obstetric outcome after intracytoplasmic sperm injection.

METHODS

The study group comprised women who delivered twins or triplets after intracytoplasmic sperm injection and standard in vitro fertilization. The incidence and main perinatal outcome of 140 multiple pregnancies resulting from intracytoplasmic sperm injection or standard in vitro fertilization treatment were analyzed.

RESULTS

A total of 60 multiple pregnancies was obtained after intracytoplasmic sperm injection (3.4 +/- 1.1 embryos/cycle) and 80 after standard in vitro fertilization (3.3 +/- 2.0 embryos/cycle). The incidence of multiple pregnancy, i.e., 22.6 compared to 20.7%, respectively, was calculated. The obstetric outcome of 47 multiple pregnancies after intracytoplasmic sperm injection was 39 twin deliveries at between 27 and 37 weeks of gestation (mean, 36 +/- 3.3) and 8 successful triplet deliveries between 26 and 36 weeks of gestation (mean 32.6 +/- 2.4). The outcome after regular in vitro fertilization was similar. No major malformations were observed.

CONCLUSIONS

The results of this study showed that the incidence of multiple pregnancies after intracytoplasmic sperm injection was similar to that after standard, conventional in vitro fertilization. The perinatal outcome did not differ between both groups.
