Melanoma of thumb: retrospective study for amputation levels, surgical margin and reconstruction.

For the treatment of melanoma of thumb, the evidence about amputation level (IP joint or MP joint) and cutaneous excision margin has not been fully presented. And reconstructions for lost thumbs need to be balanced against functional and aesthetic requirements of individual patients and overall prognosis. We report 15 patients, who underwent primary excision and reconstruction for thumb melanoma between 1986 and 2004 at Department of Plastic and Reconstructive Surgery, University of Hokkaido at Sapporo, Graduate School of Medicine. The patients were reviewed to evaluate the prognostic significance of variables including age and sex of the patient, tumour thickness, staging, level of amputation, and cutaneous excision margin. Our 15 cases were divided into two groups according to amputation level (MP or IP) and cutaneous excision margin (<40 mm or >or =40 mm) and prognosis was analysed statistically. The stage and thickness were identified as prognostic factors for disease-free survival; however, IP amputation and 10-30 mm margin did not compromise disease-free survival. Amputated thumb was reconstructed by pollicization, free toe to thumb transfer, reverse forearm flap, local flap, and skin graft. No major complication of reconstructed thumb occurred. Seven of eight cases of MP amputation were reconstructed by pollicization. On the other hand, five cases of IP amputation were reconstructed by volar skin flap in two cases, reverse forearm flap in two cases, and trimmed first toe transfer in one case. Although a small number of cases, our study is the first attempt focussing on melanoma of thumb, and evaluating amputation level and cutaneous margin separately. The reconstructive algorithm for the amputated thumb is proposed and has various tools including free toe to thumb transfer.

The national hospital discharge register data on lower limb amputations.

AIM: To study if data on lower limb amputations and vascular operations in the National Hospital Discharge Register can be used for comparison of diabetes care between hospital districts. METHODS: We identified diabetic persons from the National Hospital Discharge Register (1988-2002), the National Social Security Institute (since 1964) and pharmacies (since 1994). A search for lower limb amputations and vascular operations was made through the Hospital Discharge Register. An analysis of the correlation of the age and gender adjusted incidence of first major amputations and the age and gender adjusted incidence of first vascular operations for diabetics was made between 14 hospitals districts with the largest diabetic population. RESULTS: A total of 308,447 diabetics were identified. There were 11,070 diabetics who had a lower extremity amputation and 9530 diabetics who had a vascular operation in Finland in 1988-2002. The annual number of first amputations decreased from 924 to 387 per 100,000 diabetics during the study period. There were up to three-fold differences in age and gender adjusted indexed numbers of first amputations between different hospital districts during the last follow-up period from year 2000 to 2002. There was a clear inverse correlation between the incidence of first major amputations and first vascular operations and particularly between incidence of first major amputations and infrapopliteal reconstructions. CONCLUSION: The incidence of major amputation is declining in the diabetic population. This positive development can be explained by more active vascular operative treatment. Regional differences are wider than acceptable.

Rehabilitation and the long-term outcomes of persons with trauma-related amputations.

OBJECTIVE: To examine the long-term outcomes of persons undergoing trauma-related amputations, and to explore factors affecting their physical, social, and mental health and the role of inpatient rehabilitation in improving such outcomes. DESIGN: Abstracted medical records and interview data sought for a retrospective cohort of persons who had undergone a lower-limb trauma-related amputation. PARTICIPANTS: Patients identified with a principal or secondary diagnosis of a trauma-related amputation to the lower extremity at the University of Maryland Shock Trauma Center between 1984 and 1994. Patients with spinal cord injury or traumatic brain injury were excluded. RESULTS: Of 146 patients who had trauma-related amputations to the lower limb at the University of Maryland Shock Trauma Center during the study period, nearly 9% died during the acute admission and 3.5% died after discharge. About 87% of all trauma-related amputations involved males, and roughly three quarters involved white persons. About 80% of all amputations occurred before age 40. The health profile of traumatic amputee subjects interviewed in the study (n = 78, 68% response rate) was systematically lower than that of the general US population for all SF-36 scores. The differences in profiles were largest among SF-36 scales sensitive to differences in physical health status, particularly physical functioning, role limitations due to physical health, and bodily pain. About one fourth of persons with a trauma-related amputation reported ongoing severe problems with the residual limb, including phantom pain, wounds, and sores. The number of inpatient rehabilitation nights significantly improved the ability of patients with amputation to function in their physical roles, increased vitality, and reduced bodily pain. Inpatient rehabilitation was also significantly correlated with improved vocational outcomes. CONCLUSIONS: These findings suggest a substantial effect of inpatient rehabilitation in improving long-term outcomes of persons with trauma-related amputations.

Increased limb salvage by the use of unconventional foot amputations.

PURPOSE: Limb salvage in the presence of ischemic foot necrosis requires revascularization followed by debridement or partial foot amputation. Necrosis extending beyond the toes and metatarsal heads may require the use of unconventional types of amputations. METHODS: Over a 15-year period 2105 ischemic limbs were treated with infrainguinal revascularization. In 98 cases, extensive foot necrosis was than managed with amputations, including 59 modified Chopart, 14 Lisfranc, 17 Pirogoff and 8 Syme amputations. Patients were not allowed to bear weight for several days to weeks. RESULTS: Skin flap necrosis in 14 cases was managed successfully by debridement and skin grafting. Ambulation required the use of a "clamshell" prosthesis and foot spacer. The overall limb salvage rate in this group was 84% (82 of 98). In general, the modified Chopart amputation most frequently produced ambulatory limb salvage and is technically easier to perform than a Syme amputation. Patient satisfaction and long-term ambulatory function was highest with the modified Chopart. CONCLUSION: Ischemic foot necrosis extending beyond the limits of conventional transmetatarsal amputation need not be treated with major amputation. This requires the surgeon to be well versed in the use of less common types of partial foot amputations. Acceptable limb salvage and good functional results may be attained by the motivated patient and surgeon with the use of these procedures in the revascularized limb.

Halving the number of leg amputations: the influence of infrapopliteal bypass.

A retrospective review of amputations in patients with vascular disease during 10 years in Bispebjerg Hospital was undertaken. There were 1383 amputations leading to 1167 final level amputations. In previously independent patients there were 482 below knee amputations (BKA), 476 above knee amputations (AKA) and 43 had disarticulations in the ankle, knee or hip. During the period studied the number of final level amputations in independent patients were halved from 122 in 1981 to 58 in 1990. A similar reduction was also found in the total number of amputations: from 171 to 90, and in the number of reamputations: from 35 to 21. However, amputations in patients from long stay institutions remained at a constant level by on average 17 per year. The decrease in amputation rate took place synchronously with an increasing use of bypass to crural and pedal arteries as well as an overall increase in vascular reconstructions and angioplasties of more than 100%. However, the BKA/AKA ratio decreased from 1.12 to 0.67 (p < 0.005).

Lower extremity amputations in diabetic Mexican American elders: incidence, prevalence and correlates.

This study was designed to determine the incidence and prevalence of amputations in diabetic Mexican American elders and to identify correlates of lower extremity amputations. Data for this study came from baseline and two follow-up interviews of the Hispanic Established Population for the Epidemiological Study of the Elderly (EPESE) conducted in five southwestern states (Texas, California, New Mexico, Colorado and Arizona) in 1993-1994. Of the 3050 subjects aged 65 and older, 690 reported diabetes, and from these, 60 (8%) reported having at least one lower extremity amputation. Losing a leg was the most common type of amputation (53%). Twelve percent of respondents reported a new amputation and 40% of amputees reported a second amputation during follow-up. Mortality among amputees was 46% during a 5-year follow-up. Multiple logistic regression analysis showed that being male and having eye problems, hip fracture and diabetes for 10 or more years were significantly associated with lower extremity amputations at baseline, whereas obesity, stroke and 10 or more years with diabetes were significantly associated with new amputations at 5-year follow-up. Gender and disease history were associated with lower extremity amputations at baseline and follow-up. These variables may be useful in developing patient education and intervention programs.

Variations of rates of vascular surgical procedures for chronic critical limb ischaemia and lower limb amputation rates in western Swedish counties. The Westcoast Vascular Surgeons (WVS) Study Group.

OBJECTIVE: To assess a possible covariation between vascular surgery and amputation rates for critical limb ischaemia in defined western Swedish populations. DESIGN AND SETTING: A retrospective study during 1 year of the total number of vascular reconstructions for chronic critical leg ischaemia and amputations in the western Sweden area of health care. MAIN OUTCOME MEASURES: Correlation between vascular reconstruction and amputation rates in subpopulations. RESULTS: Patients undergoing amputation were 6 years older and had a significantly higher degree of dependent living compared with those subjected to revascularisation. The annual vascular reconstruction rate for critical limb ischaemia varied between 2 and 45, and the amputation rate between 12 and 71 per 100,000 population in the different catchment areas. There was, however, no negative correlation between amputation and revascularisation rates. CONCLUSION: We failed to demonstrate a negative correlation between amputation and revascularisation rates. Patients undergoing vascular reconstruction and amputation may represent different populations. Catchment areas with high vascular surgical activity did not have correspondingly lower amputation rates.

Determination of amputation level in ischaemic limbs using tcPO2 measurement.

BACKGROUND: Determination of the optimal amputation level is essential for patients, morbidity and rehabilitation. Various non-invasive procedures have been proposed to determine the optimal level of amputation. There is no consensus on the minimal tcPO2 level that is required to predict the healing of the stump. Therefore we aimed to rank the probability of primary wound healing at the most distal level and to answer the question if there is a lower limit of tcPO2 below which healing cannot occur. PATIENTS AND METHODS: 56 consecutive patients undergoing amputation below the knee for ischaemic gangrene of limbs were prospectively enrolled in the study. 39 were men (18 of whom were diabetics) and 17 women (8 diabetics) whose ages ranged from 45 to 87 years (mean 73 years). The total of 71 amputations was performed on the 56 patients: 39 below-knee with primary healing and, in 16 patients the above-knee reamputation was performed, due to the non-healing wound on the below-knee stump. The level of the amputation (below or above the knee) was in all cases decided solely on clinical grounds. TcPO2 was measured on each patient prior to amputation, on the dorsum of the foot and 10 cm below the knee. RESULTS: The median tcPO2 value on the dorsum of the foot of diseased legs before amputation was 12 mm Hg (range from 0 to 22 mm Hg). At the anticipated level of the amputation of the shank, the median value of tcPO2 was 28 mm Hg (8-56 mm Hg). Patients with primary healing of postoperative wounds had significantly higher values of tcPO2 than patients with fialure to heal (37 mm Hg; range 15-56 mm Hg vs. 18 mm Hg; range 8-36 mm Hg, p < 0.01). The success rate increased with higher tcPO2 values at the level of amputation. The 15% prevalence of reamputations was obtained for tcPO2 values between 25 and 36 mm Hg (median value 33 mm Hg) and the threshold value of tcPO2 below which the stump failed to heal was 15 mm Hg. CONCLUSIONS: Our study showed that tcPO2 is a reliable indicator of local ischemia. The integration of this parameter with other personal clinical criteria may be a valuable help to the surgeon in decision making.

Revisiting transtibial amputation with the long posterior flap.

BACKGROUND: The long posterior flap has been the procedure of choice for transtibial amputation for many years, but recently its theoretical basis has been challenged. This study assessed the results with the long posterior flap for leg amputation. METHODS: A prospective cohort study was performed. All patients who were referred to the Dundee Limb Fitting Centre for leg amputation between 1987 and 1996 had details of diagnosis, investigations, procedure, and both operative and functional outcome recorded contemporaneously. RESULTS: Some 126 patients required a transfemoral amputation and 445 needed a transtibial procedure. Fifty patients having the transtibial operation, who would otherwise have required a transfemoral amputation, had a medially based flap; the remaining 395 patients underwent a transtibial amputation by the long posterior flap technique. Primary healing was achieved in 317 patients, and 11 amputations healed by secondary intention. Fifty-one patients required a local wedge resection and 16 had a secondary transfemoral amputation. CONCLUSION: These results compare favourably with those of other published series. The long posterior flap remains to be bettered for routine transtibial amputation.

Aided gait of people with lower-limb amputations: comparison of 4-footed and 2-wheeled walkers.

OBJECTIVES: To test the hypotheses that prosthesis-wearing people with lower-limb amputations, using 2-wheeled walkers (TWW) versus 4-footed walkers (FFW), (1) walk faster, (2) walk with fewer interruptions, (3) walk no less safely, and (4) prefer the TWW. DESIGN: Within-subject comparisons. SETTING: Rehabilitation center. PARTICIPANTS: Twenty prosthesis-wearing people with lower-limb amputations (13 men, 7 women) with a mean age +/- standard deviation of 69+/-13 years. Of the subjects, 11 had unilateral transfemoral amputations, 7 had unilateral transtibial amputations, and 2 had bilateral transtibial amputations. INTERVENTION: Participants were trained to use both walkers. MAIN OUTCOME MEASURES: Five-meter walking velocity, gait pattern, need for spotter intervention, foot position with respect to the base of support of the walker, and subject preference. RESULTS: Subjects walked 28.5% faster when using the TWW (P=.000). During gait cycles, 100% of subjects brought the FFW to a complete halt, whereas only 55%, particularly subjects with transfemoral amputations, halted the TWW (P=.008). There was no difference in the need for spotter intervention. Subjects with unilateral amputations placed their feet significantly more anteriorly within the walker base of support when using an FFW (P=.000). Fourteen subjects preferred the TWW, and 6 chose the FFW (not significant). CONCLUSION: The TWW allows prosthesis-wearing people with lower-limb amputations, especially those with transtibial amputations, to walk more quickly and with less interruption, but no less safely, than the FFW. The findings have implications for ambulation training and the prescription of ambulation aids.

Association between age and survival following major amputation. The Scottish Vascular Audit Group.

OBJECTIVES: To determine whether age is associated with survival following major amputation and whether this association is independent or simply reflects selection bias in amputation level. DESIGN AND MATERIALS: Computer linkage of routine discharge and death data on the 2759 patients undergoing major amputation in Scotland between 1989 and 1993 for peripheral arterial disease. METHODS: Cox's proportional hazards model and multivariate logistic regression analysis using death as the outcome variable and age, sex, urgency, amputation level and recent arterial reconstructive surgery as predictor variables. RESULTS: Proximal amputation was more common in older patients. Survival was associated with both age (p < 0.001) and amputation level (p < 0.001). Age was an independent predictor of death at 30 days (p < 0.0001), 6 months (p < 0.001), 12 months (p < 0.0001) and 2 years (p < 0.0001) postoperation. CONCLUSIONS: Survival following amputation was poor, with only half the patients alive at 2 years. Above-knee amputation was associated with poorer survival, presumably due to the presence of more severe and widespread disease, and was undertaken more commonly in older patients. However, age remained a predictor of survival after adjustment for amputation level. Higher early mortality suggest that a worse prognosis in elderly patients cannot be attributed wholly to actuarial considerations.

The high-low amputation ratio: a deeper insight into diabetic foot care?

The purpose of this study was to propose and evaluate a high to low (Hi-Lo) amputation ratio as a potential additional quality measure giving further insight into high-risk foot surveillance beyond foot screening examinations. As part of the Dartmouth Atlas of Health Care project, a secondary analysis was performed on Medicare administrative data. Amputation rates were adjusted for age, gender, and race. This included 37,808 minor (foot-level) amputations and 44,599 major amputations from 1996 to 1997. We also calculated the longitudinal national trends in the Hi-Lo ratio with data from the Centers for Disease Control and Prevention from 1992 to 2002. The adjusted mean Hi-Lo ratio was 1.35 (standard deviation, 0.42). The lowest ratio was 0.56, and the highest ratio was 3.43. The correlation coefficient for the Hi-Lo ratio with major amputation rate was 0.48 (P < .0001; R2 = 0.23). Similar correlations were found for the highest and lowest percentiles for major and minor rates. The Centers for Disease Control and Prevention data of the Hi-Lo ratio using the crude and age-adjusted rates suggest stable trends in the ratio over a decade. The Hi-Lo measure demonstrates face validity, yet only a small proportion of the variance is described by local propensity to perform major amputation or by major amputation rates alone. The United States has relied on a foot screening measure alone, perhaps explaining why major amputation rates have not substantively declined. If we are to reduce the amputation burden, we should begin with a straightforward measure that can be implemented at most any center.

An analysis of outcomes of reconstruction or amputation after leg-threatening injuries.

BACKGROUND: Limb salvage for severe trauma has replaced amputation as the primary treatment in many trauma centers. However, long-term outcomes after limb reconstruction or amputation have not been fully evaluated. METHODS: We performed a multicenter, prospective, observational study to determine the functional outcomes of 569 patients with severe leg injuries resulting in reconstruction or amputation. The principal outcome measure was the Sickness Impact Profile, a multidimensional measure of self-reported health status (scores range from 0 to 100; scores for the general population average 2 to 3, and scores greater than 10 represent severe disability). Secondary outcomes included limb status and the presence or absence of major complications resulting in rehospitalization. RESULTS: At two years, there was no significant difference in scores for the Sickness Impact Profile between the amputation and reconstruction groups (12.6 vs. 11.8, P=0.53). After adjustment for the characteristics of the patients and their injuries, patients who underwent amputation had functional outcomes that were similar to those of patients who underwent reconstruction. Predictors of a poorer score for the Sickness Impact Profile included rehospitalization for a major complication, a low educational level, nonwhite race, poverty, lack of private health insurance, poor social-support network, low self-efficacy (the patient's confidence in being able to resume life activities), smoking, and involvement in disability-compensation litigation. Patients who underwent reconstruction were more likely to be rehospitalized than those who underwent amputation (47.6 percent vs. 33.9 percent, P=0.002). Similar proportions of patients who underwent amputation and patients who underwent reconstruction had returned to work by two years (53.0 percent and 49.4 percent, respectively). CONCLUSIONS: Patients with limbs at high risk for amputation can be advised that reconstruction typically results in two-year outcomes equivalent to those of amputation.

Predictors of return to work following traumatic work-related lower extremity amputation.

PURPOSE: To determine factors predictive of return to work (RTW) and days of total disability (TD) in a population of persons working at the time of lower extremity amputation. METHOD: Retrospective chart and database review. RESULTS: Of 88 valid cases, 48% involved toe amputation, 23% transtibial, 14% partial foot, 14% transfemoral, and 2% high level. Fifty-eight percent of all subjects RTW, 19% were deemed 'fit for work', and 23% did not RTW. Days TD ranged from 0 to 1664, with a mean of 366 days. Toe amputation level showed a mean of 127 days of TD. Bivariate analysis showed amputation level, total costs to Workers Compensation Board (WCB), and days TD significantly related to RTW, and rehabilitation costs, vocational rehabilitation, work assessment, age, number of surgical procedures, number of days in acute care, and amputation level significantly related to days TD. In the multivariate model, only amputation level and higher gross annual income showed predictive value for RTW. However older age, more surgical procedures, less days in hospital, and higher amputation levels were all predictive of increased days TD. CONCLUSION: Toe amputation level had a surprisingly high number of days TD, which may have significant potential economic and disability impact on the workplace. Other factors beyond simply amputation level (such as previous income level) are important considerations for RTW.

Porcine enamel matrix derivative enhances the formation of reparative dentine and dentine bridges during wound healing of amputated rat molars.

We examined the biological effects of porcine enamel matrix derivative (EMD; Emdogain) on the formation of reparative dentine and dentine bridges in rat molars after pulp amputation. The pulp chambers of upper molars of Wistar rats were perforated and the amputated pulp surfaces were directly capped with either EMD or its carrier propylene glycol alginate (PGA) as control. The cavities were then restored with glass-ionomer cement. On post-amputation days 4-30, the dissected maxillae were examined by light and electron microscopy. In PGA-capped pulp, reparative dentine had been formed over the dentine walls under the prepared cavity on day 7 post-amputation and its thickness extended until day 30. On day 30, as well as reparative dentine formation, diffuse calcification had occurred beneath the amputated wound surfaces. Dentine bridge formation under the amputated coronal pulp surface was observed in 18.2% of amputated pulp on day 30. In EMD-capped pulp, reparative dentine had already been formed by odontoblast-like cells over the dentine walls, already on day 4 post-amputation, and its thickness extended until day 30. The Ca and P weight % and Ca/P ratio of reparative dentine matrix were similar to those of pre-existing dentine matrix, and these values were not different between PGA and EMD-capped pulp. Dentine bridge formation was observed in 27.3% of EMD-capped pulp on day 30. Our results suggest that EMD enhances the formation of both reparative dentine and dentine bridges during wound healing of amputated rat molar pulp.

Clinical characteristics in relation to final amputation level in diabetic patients with foot ulcers: a prospective study of healing below or above the ankle in 187 patients.

The aim of this study was to describe the clinical characteristics in relation to final amputation level in diabetic patients with foot ulcers. In a prospective series, 187 consecutively presenting patients were investigated. From admission until final outcome, the patients were treated by a multidisciplinary team both as in- and out-patients. All the patients had one or more signs of neuropathy and 171 had evidence of peripheral vascular disease. Healing with an amputation below the ankle occurred in 74 patients, 88 patients healed with an amputation above the ankle, and 25 patients died unhealed. Amputation above the ankle was associated with high age, living in an institution, a limited walking capacity, cerebrovascular disease, congestive heart failure, and a low hemoglobin level. Amputation below the ankle was associated with diabetes diagnosis before 30 years of age and diabetes duration. In conclusion, older age, history of cerebrovascular disease and low hemoglobin level are associated with above ankle amputation level in diabetic patients with foot ulcers. However, level selection cannot be based upon these factors only, since some patients at high age, with cerebrovascular disease or with a low hemoglobin value, healed with an amputation below the ankle. None of these factors per se should be taken as a cause to choose a primary amputation above the ankle, unless amputation is supported by the total clinical picture, including local characteristics, such as type and localization of ulcer, and signs of peripheral vascular disease. More attention should be paid to biological than to chronological age.

Predicting amputation in severe ischaemia. The value of transcutaneous PO2 measurement.

The predictive value of the pedal transcutaneous oxygen tension (tcPO2) and of the distal systolic blood pressure (SBP) in forecasting the necessity for later amputation has been studied in 26 patients suffering from severe chronic ischaemia of the lower limbs. In all these patients vascular surgery had failed or not been possible, and they were threatened by amputation; they suffered from trophic lesions, or pain at rest, or both. The great toe SBP averaged 10 mmHg (range 0 to 60 mmHg) and the pedal tcPO2 10 mmHg (range 2 to 45 mmHg). After six minutes of oxygen inhalation there was an increase in pedal tcPO2 of 9 mmHg (0 to 50 mmHg). After a follow-up period averaging 7 months (range 10 days to 13 months), 13 patients underwent an amputation and nine (five of whom had been amputated) died. The great toe SBP in the patients who required amputation was initially lower than in those who did not. The pedal tcPO2 also was lower in amputated than in non-amputated patients. There was no amputation in the group showing an increase of at least 10 mmHg after six minutes of oxygen inhalation; and conversely, all patients in whom the pedal tcPO2 increased less than 10 mmHg were amputated. Thus increase in the pedal tcPO2 after oxygen inhalation appears the best criterion for estimating the prognosis of severely ischaemic limbs.

Fibular hemimelia: comparison of outcome measurments after amputation and lengthening.

BACKGROUND: Treatment of fibular hemimelia includes either Syme or Boyd amputation with early prosthetic fitting or tibial lengthening. Numerous studies have documented the success of both procedures. The purpose of our study was to compare the outcome after amputation with that after tibial lengthening, specifically with regard to activity restrictions, pain, satisfaction, complications, number of procedures, and cost, in children with fibular hemimelia. METHODS: Thirty limbs in twenty-five patients treated with either an amputation or a lengthening procedure and followed for at least two years were studied. Fifteen patients underwent amputation, and ten patients underwent lengthening of the tibia. The mean age was 1.2 years at the time of amputation and 9.7 years at the time of initial lengthening. The mean duration of follow-up was 6.9 years after the amputations and 7.1 years after the lengthening procedures. RESULTS: The patients who underwent amputation were able to perform more activities than those who had a lengthening (mean activity score, 0 compared with 1.2 points; p<0.05), and they had less pain (mean pain score, 0.2 compared with 1.2 points; p = 0.091), were more satisfied and had a lower complication rate (0.37 compared with 1.91; p<0.05). The patients who underwent amputation also had fewer procedures (1.9 compared with 7.0; p<0.05), at a lower cost ($7016 compared with $26,900; p<0.05), than those who had a lengthening. Lengthening was successful in equalizing limb lengths; the mean limb-length discrepancy, assessed in nine of eleven limbs, was 0.7 centimeter. CONCLUSIONS: This study demonstrated that children who undergo early amputation are more active, have less pain, are more satisfied, have fewer complications, undergo fewer procedures, and incur less cost than those who undergo lengthening. This was true even though good results were obtained with the lengthening procedures and most patients achieved limb-length equality, were able to walk, had minimal pain, and were quite active.
