RESUMO

Background Adequately excising varicose and incompetent perforating veins is necessary for reducing their recurrence rate of venous ulcer. Method In total, 66 venous ulcers (C6) in 1083 legs with primary varicose veins were managed through endoscopic-assisted surgery. In an endoscopic operative view, the nonvaricose, varicose, and incompetent perforating veins were clearly visualized and precisely dissected. The varicose and incompetent perforating veins were divided and completely excised. Result The varicose veins were traced to the base or periphery of the 55 ulcers. Moreover, 89.4% of the ulcers healed within 14 weeks. Kaplan-Meier analysis revealed a five-year recurrence rate of 0.0%, and the satisfaction mean score was 4.6. Conclusion Endoscopic-assisted surgery can be used to radically excise varicose veins complicated with venous ulcers; the surgery yields low recurrence and high satisfaction rates.

RESUMO

Secreted protein acidic and rich in cysteine (SPARC) is a secreted protein which is involved in various biological processes. SPARC expression is associated with tumor metastasis and poor prognosis in several types of cancer. However, the SPARC-induced signaling pathway was not fully understood in head and neck cancer. In this study, our results showed that SPARC treatment promoted cell proliferation and migration in head and neck cancer cell lines FaDu and Detroit 562. In addition, SPARC induced expression of epithelial mesenchymal transition (EMT) regulators, including Slug, Snail, and Twist in Detroit 562. The results of phospho-kinase array analysis showed that SPARC treatment increased phosphorylation of some molecules including protein kinase B (PKB/AKT), ribosomal S6 kinase (RSK), and extracellular signal-regulated kinases (ERK). The expression of SPARC-induced EMT regulator Slug was suppressed by AKT inhibitor, but not ERK and RSK inhibitors. The SPARC expression in grade IV tumor samples is higher when compared to that in grade I-III tumor samples. Our results suggest that SPARC treatment enhances the EMT signaling pathway via activation of AKT, and exogenous SPARC and tumor expressing SPARC might be associated with tumor progression in head and neck cancers.

RESUMO

BACKGROUND: Involutional blepharoptosis is the most common type of acquired blepharoptosis. The etiology is believed to be the degeneration of the levator aponeurosis, and levator superioris muscle function was believed to be normal. However, there are a few studies analyzing levator function (LF) in involutional blepharoptosis. Our study aimed to access the LF abnormality in involutional blepharoptosis and analyze the correlation between LF and ptosis severity in involutional blepharoptosis in Taiwan. METHODS: We reviewed the medical records of patients who underwent ptosis correction surgery between October 2011 and December 2015 after receiving a diagnosis of involutional blepharoptosis. This study examined patient sex and age, preoperative LF, margin reflex distance of the upper eyelid (MRD1), and ptosis severity. Linear regression was performed for statistical analysis. Levator muscle specimen was sent for pathologic examination. RESULTS: We analyzed 231 eyelids of 126 patients. Average MRD1 was 0.43 ± 2.15 mm. Average LF was 14.30 ± 2.51 mm. Overall, 77.1% (178/231) of involutional blepharoptotic eyelids had normal LF (more than 12 mm). Forty-three (18.6%) of 231 were good (10-12 mm), and 10 (4.3%) of 231 were fair (6-9 mm). No patients with poor levator function (≤5 mm) were observed in our case series. A positive correlation between LF and MRD1 was observed after statistical analysis. On average, a 0.6-mm reduction in LF was observed for each 1.0-mm decrease in MRD1. Fat infiltration in levator muscle is observed both grossly and microscopically in most cases with varied degrees. CONCLUSIONS: Levator function and MRD1 were positively correlated in patients with involutional blepharoptosis. In our study, 77.1% (178/231) of eyelids had normal levator function, which meant there was 23.0% (53/231) of eyelids had abnormal LF, in contrast to current literature. Fat infiltration was common in our series. In Asian involutional blepharoptosis, LF was not always excellent and it had positive correlation with ptosis severity.

RESUMO

BACKGROUND: Non-replantable fingertip amputation is still a clinical challenge. We performed modified composite grafting with pulp adipofascial advancement flap for Hirase IIA fingertip amputations. Results from a series of patients are presented and achieved better outcome than traditional composite grafting. PATIENTS AND METHODS: From September 2012 to April 2014, fourteen patients with sixteen digits were included in our study. Mean age of patients was 43.9 years (20-71 years). All of our patients underwent this procedure under digital block anesthesia. We performed pulp adipofascial advancement flap for better soft tissue coverage of bone exposure stump first. The amputated parts were defatted, trimming, and reattached as composite graft. Age and gender of patients, injured finger, Hirase classification, mechanism of trauma, overall graft survival area, two-point discrimination (2PD) (mm) at six-month, length of shortening of digit, The average disabilities of the arm, shoulder, and hand (DASH) score and subjective self-evaluation questionnaire at 6 month were recorded. RESULTS: Average graft survival area was 89% (75-100%). Average length of shortening was 2.2 mm (1.8-3.5 mm). 2PD at six-month after surgery was 6.3 mm in average (5-8 mm). Average DASH score at 6 month was 1.45 (0.83-2.5). The self-evaluated aesthetic results showed twelve patients (85.7%) were very satisfied, and no patient was completely unsatisfied. CONCLUSIONS: In Hirase zone IIA traumatic fingertip amputation where replantation is difficult, our modified technique of composite grafting with pulp adipofascial advancement flap provided an alternative choice with high successful rate, acceptable functional and aesthetic outcomes. © 2016 Wiley Periodicals, Inc.

RESUMO

BACKGROUND: Complex, nontraumatic diabetic foot ulcers with peripheral vascular compromise often lead to extensive lower-limb amputation. The aim of this study is to determine the outcome of combined vascular intervention and free tissue transfer for critical diabetic limb salvage. MATERIALS AND METHODS: A total of 26 consecutive diabetic patients with 28 legs with diabetic foot ulcers who underwent limb salvage with a combination of revascularization (bypass surgery or endovascular angioplasty) and free flap transfers were reviewed. There were 14 male and 12 female patients. The average age was 58.8 years (range, 35-85 years). Amputation-free survival and complete wound healing were defined as the primary endpoints. All preoperative and postoperative data were retrospectively analyzed. RESULTS: Thirty flaps were used for reconstruction in 28 legs, including 21 free anterolateral thigh (ALT) perforator flaps, 3 ALT myocutaneous flaps, 5 gracilis muscle flaps, and 1 latissimus dorsi muscle flap. All flaps used end-to-side anastomoses for the recipient artery and end-to-end anastomoses for the recipient vein. The overall flap success rate was 90% (27/30). Two flaps failed completely because of severe arteriosclerosis, which resulted in anastomosed vessel thrombosis. New flaps were applied in both cases after debridement and trimming of necrotic tissue. One flap failed because of restenosis and inadequate perfusion combined with severe infection, resulting in pedicle thrombosis. A below-knee amputation was subsequently performed. Seven flaps exhibited a partial loss, including 6 ALT perforator flaps and 1 latissimus dorsi flap, because of inadequate margin perfusion. After debridement, the flap revision and wound care, 5 flaps healed uneventfully without additional intervention. The remaining 2 ALT perforator flaps required debridement with a skin graft. The limb-salvage rates were 92.8% after 1 year and 89.2% after 5 years. CONCLUSIONS: The combination of peripheral arterial intervention and free tissue transfer resulted in successful wound healing and limb salvage instead of amputation in select diabetic patients with difficult-to-heal wounds.

RESUMO

OBJECTIVES: We determine the diagnostic performance of emergent orbital computed tomography (CT) scans for assessing globe rupture in patients with blunt facial trauma. METHODS: We performed a retrospective cohort study based on prospectively collected trauma registry and acute care surveillance data in a tertiary-care hospital. Patients aged at least 18 years who underwent isolated orbital CT scanning for assessing potential ocular trauma were examined. Analyses were performed to evaluate the magnitude of agreement between diagnosis by CT scanning and ophthalmic assessment, including globe rupture. RESULTS: Our study cohort comprised 136 patients, 30% of whom (41 patients) sustained orbital wall fractures. Concordance for orbital CT diagnosis and the ophthalmic assessment of globe rupture was substantial (k=0.708). The relative risk of globe rupture was 0.692 (95% confidence interval (CI): 0.054-8.849) for superior wall fractures, 0.459 (95% CI: 0.152-1.389) for inferior wall fractures, 2.286 (95% CI: 1.062-4.919) for lateral wall fractures, and 0.637 (95% CI: 0.215-1.886) for medial wall fractures. According to multivariate analysis, lateral wall fractures were an independent risk factor for globe ruptures (adjusted odds ratio (OR)=12.01, P=0.011), and medial or inferior wall fracture was a protective factor (adjusted OR=0.14, P=0.012). In the stratified analysis of diagnostic performance of CT scan, specificity was highest among patients with orbital wall fractures (97.2%), followed by negative predictive volume (NPV, 97%), and accuracy (95.1%). CONCLUSION: Among patients with blunt facial trauma who underwent isolated orbital CT scanning as part of ocular trauma assessment, the diagnostic performance of CT in detecting globe rupture is more accurate in patients with orbital wall fractures. Nevertheless, isolated orbital CT alone does not have a sufficiently high diagnostic performance to be reliable to rule out all globe ruptures. Lateral orbital wall fractures in blunt facial trauma patients, in particular, should prompt thorough evaluation by an ophthalmologist.

RESUMO

BACKGROUND: Numerous techniques and materials are available for increasing the dorsal height and length of the nose. Microautologous fat transplantation (MAFT) may be an appropriate strategy for augmentation rhinoplasty. OBJECTIVES: The authors sought to determine the long-term results of MAFT with the so-called one-third maneuver in Asian patients who underwent augmentation rhinoplasty. METHODS: A total of 198 patients who underwent primary augmentation rhinoplasty with MAFT were evaluated in a retrospective study. Fat was harvested by liposuction and was processed and refined by centrifugation. Minute parcels of purified fat were transplanted to the nasal dorsum with a MAFT-Gun. Patient satisfaction was scored with a 5-point Likert scale, and aesthetic outcomes were validated with pre- and postoperative photographs. RESULTS: The mean age of the patients was 45.5 years. The mean operating time for MAFT was 25 minutes, and patients underwent 1-3 MAFT sessions. The mean volume of fat delivered per session was 3.4 mL (range, 2.0-5.5 mL). Patients received follow-up for an average of 19 months (range, 6-42 months). Overall, 125 of 198 patients (63.1%) indicated that they were satisfied with the results of 1-3 sessions of MAFT. There were no major complications. CONCLUSIONS: The results of this study support MAFT as an appropriate fat-transfer strategy for Asian patients undergoing primary augmentation rhinoplasty. LEVEL OF EVIDENCE 4: Therapeutic.

RESUMO

BACKGROUND: Stromal vascular fraction (SVF) cells were used to increase the efficacy of a newly formed adipose tissue in a collagen gel in vitro. However, the outcome of the seeded cells in the collagen gel in vivo remains unknown. We traced the SVF cells in the host tissue and evaluated the efficacy of SVF for fat tissue engineering. METHODS: The aggregates implanted in the experimental and control groups were prepared by mixing SVF with the collagen gel and Dulbecco's modified Eagle medium with the collagen gel, respectively. The aggregates were implanted using a subcutaneous injection into the backs of immunodeficient mice. The aggregates were harvested 1, 2, 4, and 6 months after implantation; and 9 mice were euthanized each time. Macroscopic changes in the volume and wet weight of the aggregates were assessed. The formation of adipose tissue was studied using hematoxylin and eosin and Nile red staining. The origin and survival of adipocytes in the aggregates were examined through the immunostaining of leptin antibodies, DNA assay, and tracing of SVF cells by 1,1'-dioctadecyl-3,3,3',3'- tetramethylindocarbocyanine perchlorate labeling. RESULTS: The formation of adipose tissue was observed in all of the aggregates. Implanted human SVF cells remained in the experimental aggregates harvested after 1, 2, and 4 months but not after 6 months. At 6 months, viable adipocytes in both groups were of murine origin. Furthermore, at 6 months, the mean volume of the aggregate (P < 0.001) and the mean percentage of adipocytes (P < 0.001) were significantly higher in the experimental group than in the control group. CONCLUSIONS: Implanted SVF cells could not be traced in the aggregates harvested at 6 months but promoted the recruitment of host adipocytes to generate more adipose tissue in the experimental group than in the control group.

RESUMO

INTRODUCTION: Various management strategies have been reported for sternal wound care; however, they exhibit limited effectiveness or are associated with severe complications. Furthermore, it is difficult for the standard pectoralis major (PM) muscle advance flap to reach the lower third of the sternum. This article examines using the PM-rectus abdominis (RA) bipedicle muscle flap to treat lower-third deep sternal wound infection. METHODS: The outcomes of patients who received a PM-RA bipedicle muscle flap harvest at our institution between 1996 and 2014 were reviewed. The method involves performing a subfascial and subperiosteal dissection of the PM to elevate the muscle flap. Blunt dissection may be performed carefully under an endoscope. Endoscope visualization enables us to identify the critical structures lateral to the PM muscle. In addition, the connective tissue to the RA muscle was preserved. Continuity was carefully preserved from the pectoral-thoracoepigastric fascia to the anterior rectus sheath. The flap could then be transposed to fill the lower-third sternal tissue defect with ease. RESULTS: A total of 12 patients, with a mean age of 71 years (45-89 years), were treated using an endoscope-assisted PM-RA bipedicle muscle flap harvest. Wound microbiology of the 12 patients revealed that 3 patients had methicillin-resistant Staphylococcus aureus, 4 had S. aureus, 1 had coagulase-negative Staphylococcus, 1 had Escherichia coli, 1 had Pseudomonas aeruginosa, 1 had Mycobacterium tuberculosis, and 1 had a mixed growth of organisms. One instance of recurrent sternal infection was identified among the patients. Moreover, 1 patient died from heart failure 5 weeks after surgery, but the coverage of the sternal wound was successful. Accidental injury to the surrounding neurovascular structure of the patients was avoided, and only 10 to 15 minutes was required to divide the PM muscle. CONCLUSIONS: Performing this harvest method under endoscopic assistance has several advantages, such as preventing excess traction of the skin edge to diminish the skin slough. This method could be an effective alternative for harvesting the PM-RA bipedicle muscle flap to reconstruct the lower-third sternal wound.

RESUMO

The aim of this literature review is to examine Hering's law, a well-documented phenomenon in blepharoptosis patients, with 10% to 20% noted in cases of unilateral ptosis. Predominantly presenting as contralateral eyelid drop postoperatively, it poses a challenge for eyelid surgeons in the pursuit of symmetry and appropriate eyelid height. Proper preoperative evaluation is of utmost importance, consisting of one of either lifting test, covering test, or phenylephrine test. A deeper understanding of Hering's law further provides adequate information for optimal management of ptosis. In regard to ptosis etiology, congenital ptosis does not appear to have a distinct relation to positive Hering's law, commonly associated with a low incidence, when compared with acquired ptosis. Ptosis in the dominant eye seems to be related to a higher incidence of the phenomenon than ptosis in the nondominant eye, with statistical significance in studies ranging from P < 0.001 to P = 0.09. This can be explained as an innate response for increased innervation to regain the field of vision. Both ptosis severity and levator function appear to be of lesser importance than ptosis etiology, with minimal incidence of Hering's law in congenital ptosis regardless of these factors. It is, however, noted that ptosis severity has direct association with contralateral eyelid position in acquired ptosis, whereas there is a lack of studies for levator function. In the event of preoperative contralateral eyelid drop, surgeons should consider simultaneous surgery instead of delayed surgery for bilateral ptosis (P = 0.002). For unilateral ptosis, although reoperation is done per patient request, it may be more appropriate to first wait for roughly 2 weeks and reassess for self-regulation to a normal eyelid position.

RESUMO

PURPOSE: Treatment of blepharoptosis caused by ocular myasthenia gravis (OMG) is challenging in patients with serious side effects or failed response to medical therapy. Only a few surgical reports have been published for refractory myathenic blepharoptosis. This study is aimed at the evaluation of the surgical outcome of blepharoptosis correction in intractable OMG patients. METHODS: Twelve OMG patients who accepted frontalis sling with frontalis orbicularis oculi muscle (FOOM) flap for blepharoptosis correction were reviewed. Patients' demographies, perioperative changes of the interpalpebral fissure height (IPFH), margin reflex distance 1 (MRD1), levator function (LF), and quality of life (QOL) score were evaluated. RESULTS: The duration of OMG ranged from 3 to 31 years. LF was normal in 6 patients, good in 5, and poor in 1. There is no significant change of LF before and after surgery. MRD1 improved significantly from -1.8 mm (range, 0 to -5 mm) preoperatively to 2.9 mm (range, 2-4 mm) postoperatively. IPFH improved significantly from 3.8 mm (range, 2-6 mm) preoperatively to 7.8 mm (range, 6-9 mm) postoperatively. Upper eyelid margin was above the pupil in all patients. QOL score improved significantly from 18.2 (range, 14-23) preoperatively to 5.8 (range, 0-10) postoperatively. CONCLUSIONS: Our report reveals that surgical correction of the blepharoptosis is effective for patients with intractable OMG and that frontalis suspension with FOOM flap is a valuable option because of its ready availability and pliability. All patients are satisfied with the results, especially the improvement of QOL.

RESUMO

Intracompartmental sepsis (IS) is a rare complication in patients with burns. Intracompartmental sepsis presents in patients with inadequate perfusion of intracompartmental tissues and subsequent ischemic necrosis and infection. Contributing factors include high-volume resuscitation, delayed escharotomies, and previous bacteremia. We describe a case of massive burns from a gas explosion and the subsequent development of IS in our intensive care burn unit. The patient presented with a 75% total body surface area burn on admission, with 39% superficial, deep partial-thickness and 26% full-thickness burns. Intracompartmental sepsis was diagnosed 45 days after admission. Anterior compartment muscles, including the tibialis anterior, extensor hallucis longus, and extensor digitorum longus, were necrotic with relatively fair nerve and vascular structures. Intracompartmental sepsis is an overwhelming, infectious complication that appears late and can occur easily in patients with major burns. Early diagnosis and management are a must for improving outcomes.

RESUMO

The aim of this study was to investigate healthcare utilization and expenditure for patients with diabetes comorbid with and without mental illnesses in Taiwan. People with diabetes comorbid with and without mental illnesses in 2000 were identified and followed up to 2004 to explore the healthcare utilization and expenditure. Healthcare utilization included outpatient visits and use of hospital inpatient services, and expenditure included outpatient, inpatient and total medical expenditure. General estimation equation models were used to explore the factors associated with outpatient visits and expenditure. To identify the factors associated with hospitalization, multiple logistic regressions were applied. The average number of annual outpatient visits of the patients with mental illnesses ranged from 37.01 to 41.91, and 28.83 to 31.79 times for the patients without mental illnesses from 2000 to 2004. The average annual total expenditure for patients with mental illnesses during this period ranged from NT$77,123-NT$90,790, and NT$60,793- NT$84,984 for those without mental illnesses. After controlling for covariates, the results indicated that gender, age, mental illness and time factor were associated with outpatient visits. Gender, age, and time factor were associated with total expenditure. Age and mental illness were associated with hospitalization in logistic regression. The healthcare utilization and expenditure for patients with mental illnesses was significantly higher than for patients without mental illnesses. The factors associated with healthcare utilization and expenditure included gender, age, mental illness and time trends.

RESUMO

BACKGROUND: Intimal dissection can cause an irregular internal surface with intimal flaps and subendothelial collagen exposure. This has been associated with a high risk of thrombosis. Trimming the artery to a healthy level is routinely recommended to avoid intimal dissection. However, this method is limited when there is inadequate vascular length to work with. METHODS: We dealt with an artery exhibiting severe intimal dissection by using a new suture technique: the intimal sleeve fold-over technique. Severe arterial intimal dissections were observed in 9 (6.9%) of 130 arterial microvascular anastomoses in free flap reconstruction for oral cancer patients from January 2013 to December 2013. We used this technique in 6 of the 9 patients. RESULTS: All 6 patients were discharged as scheduled without perioperative problems and complications during follow-ups. The mean diameters of the recipient and pedicle arteries with intimal dissection were 2.13 and 2.20 mm. The mean time for performing sleeve fold-over procedure of on each artery was 5.1 minutes. CONCLUSIONS: A secure intima-to-intima contact can be achieved using this technique. This technique can provide an alternative method to intimal dissection when the length of the artery is limited.

RESUMO

Burn-induced neuropathic pain is complex, and fat grafting has reportedly improved neuropathic pain. However, the mechanism of fat grafting in improving neuropathic pain is unclear. Previous investigations have found that neuroinflammation causes neuropathic pain, and anti-inflammatory targeting may provide potential therapeutic opportunities in neuropathic pain. We hypothesized that fat grafting in burn scars improves the neuropathic pain through anti-inflammation. Burn-induced scar pain was confirmed using a mechanical response test 4 weeks after burn injuries, and autologous fat grafting in the scar area was performed simultaneously. After 4 weeks, the animals were sacrificed, and specimens were collected for the inflammation test, including COX-2, iNOS, and nNOS in the injured skin and spinal cord dorsal horns through immunohistochemistry and Western assays. Furthermore, pro-inflammatory cytokines (IL-1 ß and TNF-α) in the spinal cord were collected. Double immunofluorescent staining images for measuring p-IκB, p-NFκB, p-JNK, and TUNEL as well as Western blots of AKT, Bax/Bcl-2 for the inflammatory process, and apoptosis were analyzed. Fat grafting significantly reduced COX2, nNOS, and iNOS in the skin and spinal cord dorsal horns, as well as IL-1ß and TNF-α, compared with the burn group. Moreover, regarding the anti-inflammatory effect, the apoptosis cells in the spinal cord significantly decreased after the fat grafting in the burn injury group. Fat grafting was effective in treating burn-induced neuropathic pain through the alleviation of neuroinflammation and ameliorated spinal neuronal apoptosis.

RESUMO

BACKGROUND AIMS: Burn injuries might increase muscle mass loss, but the mechanisms are still unclear. In this study, we demonstrated that burn injury induced spinal cord ventral horn motor neuron (VHMN) apoptosis and subsequently caused muscle atrophy and revealed the potential protection of autologous adipose-derived stem cells (ASCs) transplantation on spinal cord VHMNs and muscle against burn injury. METHODS: Third-degree hind-paw burns were established by contact with a 75°C metal surface for 10 seconds. Adipose tissues were harvested from the groin fat pad, expanded in culture and labeled with chloromethyl-benzamido/1,1'-dioctadecyl-3,3,3',3'- tetramethyl indocarbocyanine perchlorate. The ASCs were transplanted into the injured hind paw at 4 weeks after burn injury. The lumbar spinal cord, sciatic nerve, gastrocnemius muscle and hind-paw skin were processed for immunofluorescent staining at 4 weeks after transplantation, including terminal deoxynucleotidyl transferase (TUNEL) assay, caspase-3, caspase-9, CD 90 and S100, and the gastrocnemius muscle was evaluated through the use of hematoxylin and eosin staining. RESULTS: Caspase-3-positive, caspase-9-positive and TUNEL-positive cells were significantly increased in the corresponding dermatome spinal cord VHMNs after burn injury. Moreover, the decrease of Schwann cells in sciatic nerve and the increase of denervation atrophy in gastrocnemius muscle were observed. Furthermore, ASCs transplantation significantly attenuated apoptotic death of VHMNs and the area of muscle denervation atrophy in the gastrocnemius muscle fibers. CONCLUSIONS: The animal model of third-degree burns in the hind paw showed significant apoptosis in the corresponding spinal cord VHMNs, which suggests that neuroprotection might be the potentially therapeutic target in burn-induced muscle atrophy. ASCs have potential neuroprotection against burn injuries through its anti-apoptotic effects.

RESUMO

OBJECTIVE: The aim of this study was to investigate and compare health care utilization and expenditures between persons with diabetes comorbid with and without anxiety disorder in Taiwan. METHODS: Health care utilization and expenditures among persons with diabetes with and without comorbid anxiety disorder in the period 2000-2004 were examined using the Taiwan's National Health Insurance claims data. Health care utilization included outpatient visits and use of hospital inpatient services, while expenditures included outpatient, inpatient and total medical expenditures. General estimation equation (GEE) models were used to analyze the factors associated with outpatient visits and expenditures, and multiple logistic regression analysis was applied to identify factors associated with hospitalization. RESULTS: In the study period, the average number of annual outpatient visits was 43.11-50.37 and 29.82-31.42 for persons with diabetes comorbid with anxiety disorder and for those without anxiety disorder, respectively. The average annual total expenditure was NT$74,875-92,781 and NT$63,764-81,667, respectively. Controlling for covariates, the GEE models revealed that age and time were associated with outpatient visits. Income and time factor were associated with total expenditure. CONCLUSIONS: Health care utilization and expenditures for persons with diabetes with comorbid anxiety disorder are significantly higher than those without anxiety disorder. The factors associated with health care utilization and expenditures are age, income and time.

RESUMO

BACKGROUND: Muscle infarction is a rare complication of spontaneous ischemic necrosis occurring in skeletal muscle. It is particularly common in patients with diabetes who have impaired sugar regulation. However, muscle infarction is frequently misdiagnosed due to varied clinical manifestations. METHODS: We presented 3 cases of muscle infarction reported during April 2009 to April 2014. After a comprehensive literature review, we selected 147 muscle infarction cases from the literature, first investigating the relationships between type of muscle blood supply and infarcted muscle. RESULTS: The result indicated that muscle infarction 25.85% belonged to type I vascular supply and 61.21% belonged to type II vascular supply, according to the definition by Mathes and Nahai. CONCLUSIONS: Poor glucose regulation, intense exercise without adequate hydration, vascular disease, and type I and II muscular blood supply were critical predisposing factors. For preventing muscle infarction, we recommend strict glucose regulation and a gradual increase in exercise with adequate hydration.
