ABSTRACT

Advanced ankle arthritis, avascular osteonecrosis, and osteomyelitis of the ankle remain a surgical challenge in the foot and ankle arena with limited treatment options. Multiple medical comorbidities contribute to total loss of the talus. Collapse of the talar body as a complication of total ankle arthroplasty, talectomy in infection, and septic talus necrosis or severe bone defects caused by tumor resection may result in need for total talar replacement. Ankle arthrodesis and tibiocalcaneal fusion after talectomy can produce severe disability of the ankle and foot. Total ankle replacement is a viable option for treatment of end-stage ankle arthritis in appropriate patient populations.

ABSTRACT

Sickle cell disease (SCD) is associated with episodes of severe vaso-occlusive pain beginning in infancy with a subset of patients with SCD transitioning to chronic pain. Response to experimental pain using quantitative sensory testing in these patients suggests altered pain processing. The objectives of this study were to characterize sensitivity to multiple modalities of experimental pain stimuli and to interrogate the relationship of psychological covariates, clinical pain burden, and pain-related outcomes to experimental pain sensitivity in children with SCD compared with healthy individuals of similar age and sex. Cross-sectional assessments of psychological characteristics were performed, and quantitative sensory testing methods were used to measure experimental pain sensitivity in children age 8 to 21 years. Anxiety, depressive symptoms, catastrophizing, and somatization were found to be associated with increased sensitivity to experimental pain stimuli. Increased frequency of painful episodes in SCD was associated with decreased sensitivity to heat pain and decreased mechanical temporal summation. These data suggest that careful consideration be given to psychological factors, age, sex, and clinical burden of pain when studying response to experimental pain in SCD. PERSPECTIVE: In this study of patients with SCD, a condition associated with recurrent acute or chronic pain, psychological factors such as depression, anxiety, and catastrophizing are associated with increased sensitivity to experimental pain stimuli. Further study is need to delineate the role of these factors in chronic SCD pain.

ABSTRACT

INTRODUCTION: Unintentional dural puncture (UDP) and postdural puncture headache (PDPH) occur during the course of epidural catheter placement for labor analgesia with a reported incidence of 1%-5%. After UDP with an epidural needle, 80%-86% of patients develop PDPH. Acute symptoms after UDP are well known. However, few studies have evaluated the long-term complications of UDP, which is important in assisting parturients in the decision-making informed consent process. We sought to elucidate the long-term (>6 weeks) sequelae of PDPH by examining parturients who had UDP (both recognized and unrecognized) associated with labor epidural analgesia. METHODS: Parturients with a documented UDP (n = 308) over a 5-year period were followed up for acute and long-term residual symptoms (lasting >6 weeks) and compared with a control group (no documented UDP, n = 50) in the same period. Specific symptoms included headache, backache, neck ache, auditory symptoms, and visual symptoms. RESULTS: In comparing parturients with a UDP with control group (no UDP), differences were noted in overall acute symptoms (75.9% vs 21.7%, P < .001), specifically headache (87.0% vs 8.7%, P < .001), backache (47.2% vs 19.6%, P = .002), neck ache (30.1% vs 2.2%, P < .001), auditory (13.8% vs 0%, P = .02), and visual symptoms (19.5% vs 0%, P = .002). Differences were also noted in comparing chronic symptoms (26.5% vs 10.9%, P = .04) and specifically with respect to chronic headache (34.9% vs 2.2%, P < .001), backache (58.1% vs 4.4%, P < .001), and neck ache (14.0% vs 0%, P = .02). No differences were noted between groups in comparing chronic auditory and visual symptoms. CONCLUSION: Chronic headache and backache sequelae persist in the obstetrical population after UDP. When parturients are considering labor epidural analgesia, long-term sequelae should be discussed in the informed consent decision-making process.

ABSTRACT

UNLABELLED: Persistent postmastectomy pain (PPMP) is increasingly recognized as a major individual and public health problem. Although previous studies have investigated surgical, medical, and demographic risk factors, in this study we aimed to more clearly elucidate the relationship of psychosocial factors to PPMP. Postmastectomy patients (611) were queried about pain location, severity, and burden 38.3 ± 35.4 months postoperatively. Validated questionnaires for depressive symptoms, anxiety, sleep, perceived stress, emotional stability, somatization, and catastrophizing were administered. Detailed surgical, medical, and treatment information was abstracted from patients' medical records. One third (32.5%) of patients reported PPMP, defined as ≥3/10 pain severity in the breast, axilla, side, or arm, which did not vary according to time since surgery. Multiple regression analysis revealed significant and independent associations between PPMP and psychosocial factors, including catastrophizing, somatization, anxiety, and sleep disturbance. Conversely, treatment-related factors including surgical type, axillary node dissection, surgical complication, recurrence, tumor size, radiation, and chemotherapy were not significantly associated with PPMP. These data confirm previous studies suggesting that PPMP is relatively common and provide new evidence of significant associations between psychosocial characteristics such as catastrophizing with PPMP, regardless of the surgical and medical treatment that patients receive, which may lead to novel strategies in PPMP prevention and treatment. PERSPECTIVE: This cross-sectional cohort study of 611 postmastectomy patients investigated severity, location, and frequency of pain a mean of 3.2 years after surgery. Significant associations between pain severity and individual psychosocial attributes such as catastrophizing were found, whereas demographic, surgical, medical, and treatment-related factors were not associated with persistent pain.

ABSTRACT

Persistent postmastectomy pain (PPMP) is a major individual and public health problem. Increasingly, psychosocial factors such as anxiety and catastrophizing are being revealed as crucial contributors to individual differences in pain processing and outcomes. Furthermore, differences in patients' responses to standardized quantitative sensory testing (QST) may aid in the discernment of who is at risk for acute and chronic pain after surgery. However, characterization of the variables that differentiate those with PPMP from those whose acute postoperative pain resolves is currently incomplete. The purpose of this study was to investigate important surgical, treatment-related, demographic, psychophysical, and psychosocial factors associated with PPMP by comparing PPMP cases with PPMP-free controls. Pain was assessed using the breast cancer pain questionnaire to determine the presence and extent of PPMP. Psychosocial and demographic information were gathered via phone interview, and women underwent a QST session. Consistent with most prior research, surgical and disease-related variables did not differ significantly between cases and controls. Furthermore, treatment with radiation, chemotherapy, or hormone therapy was also not more common among those with PPMP. In contrast, women with PPMP did show elevated levels of distress-related psychosocial factors such as anxiety, depression, catastrophizing, and somatization. Finally, QST in nonsurgical body areas revealed increased sensitivity to mechanical stimulation among PPMP cases, while thermal pain responses were not different between the groups. These findings suggest that an individual's psychophysical and psychosocial profile may be more strongly related to PPMP than their surgical treatment.
