RESUMEN

BACKGROUND: Although laser Doppler imaging (LDI) accurately delineates a hypoperfused area to help target hyaluronidase treatment, laser speckle contrast imaging (LSCI) is more appropriate for assessing microvascular hemodynamics and has greater reproducibility than LDI. This study investigated the use of LSCI in the evaluation and treatment of six patients who developed vascular complications after facial dermal filler injections. METHODS: The areas of vascular occlusion were accurately defined in real time by LSCI and were more precise than visual inspections or photographic evidence for guiding needling and hyaluronidase treatment. RESULTS: All patients had achieved satisfactory outcomes as early as Day 2 of treatment and no procedure-related complications were reported after a median follow-up of 9.5 (7-37) days. CONCLUSION: LSCI accurately and noninvasively delineated vascular occlusions in real time among patients experiencing complications of facial dermal filler injections. Moreover, LSCI was more accurate than visual and photographic evaluations. Clinicians can use LSCI to reliably follow-up therapeutic outcomes after salvage interventions for vascular occlusions.

RESUMEN

ABSTRACT: Kimura disease (KD) is a rare, chronic inflammatory disorder presenting with solitary or multiple masses. Treatment options include surgical excision, corticosteroids, and radiotherapy; however, optimal therapy remains to be established. Moreover, efficacy of a humanized monoclonal antibody, dupilumab (Dupixent), requires to be demonstrated. Here, we present a 36-year-old male patient with an enlarging mass in the left medial thigh and chronic eczema over the abdomen and lower legs. Kimura disease was diagnosed after surgical excision. Postoperative treatment with dupilumab was applied with an initial dose of 600 mg followed by 300 mg every 2 weeks for 8 months. No recurrence of KD was observed in the 1-year follow-up. The eczematous lesions improved greatly. To our knowledge, this is the first report of using dupilumab for treating KD.

RESUMEN

BACKGROUND: Although blood test is a routine in major burns, its relationship with burn size and intensive care unit length of stay (ICULOS) remains undetermined. We investigated the feasibility of using these tests as a reference for definite diagnosis of major burn size, burn size >20% of the total body surface area (TBSA), and their relationships with ICULOS. METHODS: Data of routine laboratory blood tests within 24 h after burns (n = 73) were collected retrospectively. Correlation tests and regression analyses were performed. RESULTS: Burns ≥20 TBSA had higher incidences of leucocytosis, hypoalbuminaemia, elevated haemoglobin (Hb), and elevated haematocrit (Hct). Burn size was correlated negatively with albumin but positively with Hb, Hct, and white blood cell (WBC) count. For each unit increase in blood urea nitrogen (BUN)/creatinine (Cr), there was an increase of 1.2 days of ICULOS in females, while in males, there was a 6.7 day increase for every unit increase in Hb and a 3.1 day increase for each unit increase in BUN. A female model including Hb and WBC was derived, discriminating burns ≥20 TBSA with sensitivity and specificity 0.94 and 1.0 respectively, and area under the receiver operating characteristic curve (AUROC) 0.96 (95% CI 0.91-1.00). The male model had sensitivity 0.96, specificity 1.0, and AUROC 0.96 (95% CI 0.89-1.00). CONCLUSION: Admission Hb and WBC could be used as a reference for definite diagnosis of major burn size, especially in borderline cases. BUN/Cr in females, and Hb and BUN in males, were related to ICULOS.

RESUMEN

Few studies have assessed the efficacy and safety of reconstruction of sternal infection using a pectoralis muscle flap combined with a rectus abdominis muscle (RAM) sheath fasciocutaneous flap. We report here our experience with this procedure to reconstruct the sternal defect in patients (n = 46) with a deep sternal wound infection (DSWI) after cardiac surgery. After wound reconstruction, the proportion of prolonged mechanical ventilation use and intensive care unit (ICU) stay were 17.4% (n = 8) and 21.7% (n = 10), respectively. The 30-day all-cause mortality was 15.2%; recurrence rate was 17.4%; postoperative complications were 15.2%; and median hospital stay was 31 (0-157) days. Multivariate logistic regression analysis revealed that hypertension (ß = 21.32, 95%CI 4.955-37.68, P = .014), drainage-tube use (ß = 0.944, 95%CI 0.273-1.614, P = .008), and prolonged intensive care unit stay (ß = 53.65, 95%CI 31.353-75.938, P < .001) were significantly correlated with hospital stay. In conclusion, a procedure including surgical debridement, sternal reconstruction with bilateral PM and RAM sheath flap, long-term antibiotics, and adequate drainage is a beneficial technique in the reconstruction of deep sternal wound infection after cardiac surgery. Duration of drainage tube use may be as an index for a hospital stay or wound healing.

RESUMEN

ABSTRACT: The Morel-Lavallée lesion (MLL) is a posttraumatic close degloving injury, which is often underdiagnosed at first. Patients with MLLs usually present with tender and enlarging soft tissue swelling with fluctuation, decreased skin sensation, ecchymosis, or even skin necrosis hours to days after the inciting injury. The lesion can lead to intractable morbidity if it remains untreated. There is no consensus regarding the treatment for MLL at present. Here, we report an MLL in the pretibial region of a 43-year-old woman who experienced a low-energy contusion in a motorbike accident. The pretibial lesion was diagnosed using sonography and fine-needle aspiration. We successfully treated the patient by performing percutaneous debridement via a small incision and injections of fibrin after conservative treatment failed. The method we herein propose achieved the goal of open surgical debridement, providing faster recovery and a high degree of patient comfort. We reviewed the available pertinent literature and propose our own treatment protocol with the aim to establish common therapies ofMLL.

RESUMEN

BACKGROUND: An iatrogenic tracheoesophageal (TE) fistula is one possible complication after total laryngectomy with flap reconstruction. We used sternocleidomastoid (SCM) rotation flap to close a TE fistula. METHODS AND RESULTS: A 69-year-old man with laryngeal cancer underwent total laryngectomy with radial forearm free flap reconstruction. A tracheostoma stenosis was noticed 7 months after the tracheostomy tube was removed. The patient underwent tracheostoma dilatation; the iatrogenic TE fistula was noticed 1 month later. We used SCM rotation flap to close the TE fistula. The postoperative course was uneventful. A barium esophagogram showed no leakage in the esophagus. CONCLUSIONS: Tracheoesophageal fistula can be reconstructed with an SCM rotation flap. If the TE fistula is of a suitable size, this reconstructive strategy is effective and simple to close persistent TE fistula and avoid further airway complications.

RESUMEN

Objective: Hard-to-heal diabetic foot ulcers (DFUs) are associated with higher mortality rates and an increased medical burden for patients. ON101, a new topical cream, exhibited better healing efficacy than the control dressing in a Phase III trial. In this post hoc analysis, we further identify whether ON101 can improve the healing of ulcers with hard-to-heal risk factors in this cohort of DFU patients. Approach: To compare the efficacy of ON101 with absorbent dressing among various hard-to-heal wounds in patients with DFU, a post hoc analysis of a randomized Phase III trial that included 276 DFU patients was performed by subgrouping those patients based on ulcer depth, location, size, duration, and patients' glycated hemoglobin (HbA1c) levels and body mass index (BMI). Results: In the full analysis set, the proportion of patients achieving healing was 61.7% in the ON101 group and 37.0% in the comparator (p = 0.0001). In subgroup analysis according to risk factors, ON101 demonstrated superior healing capacity on Wagner grade 2 ulcers (p < 0.0001); plantar ulcers (p = 0.0016), ulcer size ≥5 cm2 (p = 0.0122), ulcer duration ≥3 months (p = 0.0043); for patients with HbA1c ≥9% (p = 0.0285); and patients with BMI ≥25 (p = 0.0005). Innovation: ON101, a novel therapeutic drug, can modulate the functions of macrophages and demonstrate superior healing rates to conventional absorbent dressing in patients with hard-to-heal DFUs. Conclusions: The results of this post hoc study suggest that ON101 is a better therapeutic option than conventional dressing used in treatment for DFU patients with higher HbA1c, BMI, or ulcers with complex conditions such as longer duration, deeper wounds, larger size, and plantar location.

RESUMEN

Transumbilical breast augmentation with pre-filled silicone implants has been performed previously, but technical challenges remain to accommodate more implant options and dissection planes. We aimed to demonstrate the feasibility of transumbilical breast augmentation using various types of pre-filled silicone implants (TUSBA), and its applicability for subglandular, subfascial, dual-plane implantation. In the early stage, TUSBA was primarily performed using endoscope-assisted blunt dissection, and later converted to full endoscopy dissection to achieve better results. Endoscope was used to confirm the pocket and check bleeding for both groups. For endoscope-assisted group, surgical techniques were modified from conventional TUBA. In full endoscopy TUSBA, the entire dissection process was performed under endoscopic monitoring. Preliminary data of patients undergoing TUSBA from June 2016 to April 2021 were retrospectively reviewed. Breast implants with smooth, textured or nanotextured surface properties and round or anatomical shapes were used, with sizes up to 500 mL. Seventy-four patients with mean age 36.4 years (range: 21-55 years) were enrolled in this study. Follow-up ranged from 1 month to 4 years and 6 months (mean: 15.6 months). No excessive postoperative pain in breast or abdomen was reported. Surgery outcomes were aesthetically pleasing in both groups. In the endoscope-assisted group, 3 (4.6%) required major revisional procedures. No revision was required in the full endoscopy group. TUSBA with various types of silicone implants is feasible, and accommodable to all dissection planes. Full endoscopy technique is helpful in reducing the higher complication rate.

RESUMEN

INTRODUCTION: Mallet fractures are avulsions of the terminal extensor tendon from the base of the distal phalangeal bone with a bony fragment. Surgical treatment, which provides accurate anatomical reduction and rigid fixation, is recommended for mallet fractures with involvement of more than one third of the base of the distal phalangeal bone. Various surgical methods have been reported, but there is still no standard treatment modality. The purpose of this investigation was to assess the results of our modified tenodesis method for mallet fractures. MATERIALS AND METHODS: Using our method, the dorsal fracture fragment was reduced and fixed to the main part of the distal phalangeal bone by 2 stitches of "figure-of-eight" 4-0 Prolene sutures. We reviewed 12 consecutive patients with 13 mallet fractures treated with our modified tenodesis method between January 2009 and March 2012. This retrospective study was composed of 7 male and 5 female patients, with a mean age of 35.7 years (range, 25-56 years). All patients underwent surgical treatment and sequent 3-week finger splinting. Patient follow-up lasted 3 to 6 months, with a mean period of 5.2 months. RESULTS: The modified tenodesis method allowed accurate anatomical reconstruction of the injured extensor mechanism. Grading by Crawford criteria showed that the outcome was "excellent" in 8 of 13 digits and "good" in 5 of 13 digits. The follow-up hand x-rays also revealed congruent joint surfaces of distal interphalangeal joints with no evidence of joint space narrowing. No wound complications were encountered, and all the patients returned to normal activities without any disability. CONCLUSIONS: The modified tenodesis method is simple and effective to provide accurate anatomical reduction and fixation for treatment of type I mallet fractures. No device penetration of the small bony fragment or pinning through the distal interphalangeal joint is required, and the surgical complication rate is low. We recommend this treatment modality for all but chronic cases.

RESUMEN

Background: Reuse of cardiac implantable electronic devices (CIEDs) can reduce the cost of using these expensive devices. However, whether resterilized CIEDs will increase the risk of reinfection in patients with previous device infection remains unknown. The aim of the present study is to compare the reinfection rates in patients who had initial CIED infection and underwent reimplantation of resterilized CIEDs or new devices. Methods: Data from patients with initial CIED infection who received debridement of the infected pocket and underwent reimplantation of new or resterilized CIEDs at MacKay Memorial Hospital, Taipei, Taiwan, between January 2014 and June 2019 were retrospectively analyzed. Patient characteristics, relapse rates of infection, and potential contributing factors to the infection risk were examined. Results: Twenty-seven patients with initial CIED infection and reimplanted new CIEDs (n = 11) or resterilized CIEDs (n = 16) were included. During the 2-year follow-up, there were 1 (9.1%) and 2 (12.5%) infection relapses in the new and resterilized CIED groups, respectively. No relapse occurred for either group if the lead was completely removed or cut short. The median duration between debridement and device reimplantation in patients with infection relapse vs patients without relapse was 97 vs 4.5 days for all included patients, and 97 vs 2 days and 50.5 vs 5.5 days for the new and resterilized CIED groups, respectively. Conclusions: Subpectoral reimplanting of resterilized CIEDs in patients with previous device infection is safe and efficacious. With delicate debridement and complete extraction of the leads, the CIED pocket infection relapse risk can be greatly decreased.

RESUMEN

Vascular occlusion is a rare but severe complication of dermal filler injections. Early treatment of this complication produces better outcomes. Current diagnostic methods for vascular occlusion in the skin are subjective and imprecise; these include capillary refill time, skin color, and reports of pain. This study aimed to assess the use of laser Doppler imaging (LDI) in the evaluation and treatment of vascular complications caused by dermal filler injections. This retrospective study used laser Doppler imaging (LDI) in 13 patients who developed vascular occlusion after facial dermal filler injections, with subsequent follow-up. The precise areas of perfusion observed on LDI were compared with the findings of clinical and photographic evaluation. The results showed that LDI accurately identified areas of vascular occlusion and improved treatment precision among these thirteen patients. The procedure was more precise than visual inspection or photographic evidence. Satisfactory outcomes were achieved for all patients, and no procedure-related complications were reported. Collectively, LDI provides fast, noninvasive, and accurate delineation of areas of vascular occlusion caused by complications of dermal filler injections and avoids several subjective shortcomings of visual and photographic evaluations. Thus, LDI effectively tracks treatment outcomes. However, large-scale studies are required to confirm the present findings.

RESUMEN

Importance: Delayed healing of diabetic foot ulcers (DFUs) is known to be caused by dysregulated M1/M2-type macrophages, and restoring the balance between these macrophage types plays a critical role in healing. However, drugs used to regulate M1/M2 macrophages have not yet been studied in large randomized clinical trials. Objective: To compare the topical application of ON101 cream with use of an absorbent dressing (Hydrofiber; ConvaTec Ltd) when treating DFUs. Design, Setting, and Participants: This multicenter, evaluator-blinded, phase 3 randomized clinical trial was performed in 21 clinical and medical centers across the US, China, and Taiwan from November 23, 2012, to May 11, 2020. Eligible patients with debrided DFUs of 1 to 25 cm2 present for at least 4 weeks and with Wagner grade 1 or 2 were randomized 1:1 to receive ON101 or control absorbent dressings. Interventions: Twice-daily applications of ON101 or a absorbent dressing changed once daily or 2 to 3 times a week for 16 weeks, with a 12-week follow-up. Main Outcomes and Measures: The primary outcome was the incidence of complete healing, defined as complete re-epithelialization at 2 consecutive visits during the treatment period assessed on the full-analysis set (FAS) of all participants with postrandomization data collected. Safety outcomes included assessment of the incidences of adverse events, clinical laboratory values, and vital signs. Results: In the FAS, 236 eligible patients (175 men [74.2%]; mean [SD] age, 57.0 [10.9] years; mean [SD] glycated hemoglobin level, 8.1% [1.6%]) with DFUs classified as Wagner grade 1 or 2 (mean [SD] ulcer area, 4.8 [4.4] cm2) were randomized to receive either the ON101 cream (n = 122) or the absorbent dressing (n = 114) for as long as 16 weeks. The incidence of complete healing in the FAS included 74 patients (60.7%) in the ON101 group and 40 (35.1%) in the comparator group during the 16-week treatment period (difference, 25.6 percentage points; odds ratio, 2.84; 95% CI, 1.66-4.84; P < .001). A total of 7 (5.7%) treatment-emergent adverse events occurred in the ON101 group vs 5 (4.4%) in the comparator group. No treatment-related serious adverse events occurred in the ON101 group vs 1 (0.9%) in the comparator group. Conclusions and Relevance: In this multicenter randomized clinical trial, ON101 exhibited better healing efficacy than absorbent dressing alone in the treatment of DFUs and showed consistent efficacy among all patients, including those with DFU-related risk factors (glycated hemoglobin level, ≥9%; ulcer area, >5 cm2; and DFU duration, ≥6 months). Trial Registration: ClinicalTrials.gov Identifier: NCT01898923.

RESUMEN

A bilobed free radial forearm flap was designed to reconstruct a defect in the epiglottis and tongue base in 2 patients who underwent supraglottic laryngectomy. The flap was initially sutured in the shape of the epiglottis to prevent aspiration during deglutition. Six months after surgery, after a full course of radiation therapy, the flap had flattened and underwent atrophy, but the patients still had good voice production and were able to swallow well without any aspiration. Regardless of the final shape of the reconstructed epiglottis, it will suffice to prevent aspiration if the flap is large enough to occlude the tracheal outlet.

RESUMEN

PURPOSE: To study outcomes among survivors of the mass-casualty powder explosion on 27 June 2015, at Formosa Fun Coast Waterpark, New Taipei City, Taiwan. METHODS: Using retrospective data on Taiwanese survivors, we analyzed prehospital management, burns assessment and prognosis, functional recovery, and medical costs, followed-up through 30 June 2017. We related outcomes to burn extent, categorized according to the percentages of total body surface area with second/third-degree burns (%TBSA) or autologous split-thickness skin grafts (%STSG), and an investigational scale: f{SASG} = (%TBSA + %STSG)/2, stratified by %STSG. Analyses included casualty dispersal, comparisons between %TBSA, %STSG and f{SASG}, and their relationships with length of hospitalization, times to rehabilitation and social/school re-entry, physical/mental disability, and medical costs. We also investigated how burn scars restricting joint mobility affected rehabilitation duration. RESULTS: 445 hospitalized casualties (excluding 16 foreigners, 23 with 0% TBSA and 15 fatalities) aged 12-38 years, had mean TBSA of 41.1%. Hospitalization and functional recovery durations correlated with %TBSA, %STSG and f{SASG} - mean length of stay per %TBSA was 1.5 days; more numerous burn scar contractures prolonged rehabilitation. Females had worse burns than males, longer hospitalization and rehabilitation, and later school/social re-entry; at follow-up, 62.3% versus 37.7% had disabilities and 57.7% versus 42.3% suffered mental trauma (all p ≤ 0.001). Disabilities affecting 225/227 people were skin-related; 34 were severely disabled but 193 had mild/moderate impairments. The prevalence of stress-related and mood disorders increased with burn extent. Treatment costs (mean USD-equivalents ∼$48,977/patient, ∼$1192/%TBSA) increased with burn severity; however, the highest %TBSA, %STSG and f{SASG} categories accounted for <10% of total costs, whereas TBSA 41-80% accounted for 73.2%. CONCLUSIONS: Besides %TBSA, skin-graft requirements and burn scar contractures are complementary determinants of medium/long-term outcomes. We recommend further elucidation of factors that influence burn survivors' recovery, long-term physical and mental well-being, and quality of life.

RESUMEN

Sixteen patients with hypopharyngeal carcinoma who underwent laryngopharyngectomy had immediate reconstruction with a free ileocolic flap to restore voice and swallowing. All patients had satisfactory voice production and swallowing in the early postoperative stage. Maintaining adequate tension and decreasing redundancy of the transferred colon prevented food pooling and provided smooth, rapid swallowing. A wedge resection of the subserosa of the ileocecal valve to increase the intraluminal pressure helped prevent food reflux and provide good phonation. Although this modified technique yielded good initial results, both voice and swallowing deteriorated after concurrent chemoradiotherapy, possibly because of radiation injury to the transferred bowel.

RESUMEN

BACKGROUND: Gynecomastia is enlargement of the male breast caused by gland proliferation. Surgery is performed for symptom relief or for cosmetic reasons. The authors used a modified operative procedure, then evaluated the results and safety. METHODS: Between 2001 and 2005, 22 men (median age, 26 years; range, 13-63 years) with gynecomastia underwent surgery. The operative procedure included a zigzag periareolar skin incision, eccentric subcutaneous mastectomy, and liposuction, with postoperative compression. RESULTS: All the patients were satisfied with the results of the surgery, which produced a chest contour resembling a normal male chest rather than simply a smaller breast. The only complication was a hematoma. One patient was found to have breast cancer. CONCLUSIONS: The normal male chest contour can be restored by the described method of eccentric subcutaneous mastectomy.

RESUMEN

Hand burns cause functional impairment. Leap motion control (LMC), a kind of virtual reality games, employs a novel system that provides biofeedback and training of fine motor function and functional skills. In this study, we hypothesized that LMC would improve burned hand function. Sixteen participants were allocated to either the LMC group or the control group. The LMC group played 20min identical leap motion video games after 40min traditional occupational therapy (OT). The control group received traditional OT for 60min. Both groups received interventions 2 days a week for 4 months. A series of questionnaires were administered, including BSHS-B, QuickDASH, iADL, and Barthel index. Data on baseline characteristics including joint range of motion (ROM), grip and pinch strength, and scar thickness were obtained. Furthermore, we used the Mann-Whitney U test and Wilcoxon signed-rank test for comparison, as appropriate. We found improvements in BSHS-B, QuickDASH, and iADL in the LMC group (all p<0.05) compared to those in the control group. In the LMC-trained hand, the ROM of the thumb IP joint and pinch strength increased, whereas the scar thickness over the first dorsal interossei muscle decreased (p<0.05). In conclusion, leap motion training could help patients with hand burns to increase finger ROM, decrease scar thickness, and improve hand function.

RESUMEN

BACKGROUND: Tendon stem/progenitor cells (TSPC) exhibit a low proliferative response to heal tendon injury, leading to limited regeneration outcomes. Exogenous growth factors that activate TSPC proliferation have emerged as a promising approach for treatment. Here, we evaluated the pigment epithelial-derived factor (PEDF)-derived short peptide (PSP; 29-mer) for treating acute tendon injury and to determine the timing and anatomical features of CD146- and necleostemin-positive TSPC in the tendon healing process. METHODS: Tendon cells were isolated from rabbit Achilles tendons, stimulated by the 29-mer and analyzed for colony-forming capacity. The expression of the TSPC markers CD146, Oct4, and nestin, induced by the 29-mer, was examined by immunostaining and western blotting. Tendo-Achilles injury was induced in rats by full-thickness insertion of an 18-G needle and immediately treated topically with an alginate gel, loaded with 29-mer. The distribution of TSPC in the injured tendon and their proliferation were monitored using immunohistochemistry with antibodies to CD146 and nucleostemin and by BrdU labeling. RESULTS: TSPC markers were enriched among the primary tendon cells when stimulated by the 29-mer. The 29-mer also induced the clonogenicity of CD146+ TSPC, implying TSPC stemness was retained during TSPC expansion in culture. Correspondingly, the expanded TSPC differentiated readily into tenocyte-like cells after removal of the 29-mer from culture. 29-mer/alginate gel treatment caused extensive expansion of CD146+ TSPC in their niche on postoperative day 2, followed by infiltration of CD146+/BrdU- TSPC into the injured tendon on day 7. The nucleostemin+ TSPC were located predominantly in the healing region of the injured tendon in the later phase (day 7) and exhibited proliferative capacity. By 3 weeks, 29-mer-treated tendons showed more organized collagen fiber regeneration and higher tensile strength than control tendons. In culture, the mitogenic effect of the 29-mer was found to be mediated by the phosphorylation of ERK2 and STAT3 in nucleostemin+ TSPC. CONCLUSIONS: The anatomical analysis of TSPC populations in the wound healing process supports the hypothesis that substantial expansion of resident TSPC by exogenous growth factor is beneficial for tendon healing. The study suggests that synthetic 29-mer peptide may be an innovative therapy for acute tendon rupture.

RESUMEN

This study examined the psychometric properties of the Chinese version of the Post-traumatic Syndrome Scale-Interview (C-PSSI) for severe burn victims of the Formosa Fun Coast Explosion that occurred in Taiwan. A purposive sampling, cross-sectional, descriptive design study was selected. Participants were patients with severe burns from the Formosa Fun Coast Explosion, selected from teaching medical centers in Taiwan. They completed the C-PSSI and Patient Health Questionnaire-9 (PHQ-9). Statistical analysis was conducted to evaluate the psychometric properties, including reliability, construct validity (using confirmatory factor analysis), convergent validity, and criterion-related validity of the questionnaire. Data on 63 participants were analyzed. The Cronbach's α of the entire C-PSSI was .88, ranging from .73 to .82 for the three subscales of this instrument. The item-total correlation coefficient was from .42 to .81. Examining the convergent validity revealed that two subscores of the C-PSSI were significantly correlated with PHQ-9 total scores (ρ = .58, .44, P < .01). Criterion-related validity was confirmed because the PHQ-9 total scores were significantly correlated with the total C-PSSI scores (ρ = .54, P < .01). Confirmatory factor analysis confirmed the construct validity, with a good model fit. Integrated moderate to good psychometric properties were demonstrated and a three-factor model of the C-PSSI was verified in patients with severe burn in Taiwan. The C-PSSI exhibited adequate psychometric properties for posttraumatic stress disorder evaluation in patients with severe burn in Taiwan. The Chinese version of this scale can be used to assess the psychological problems of victims of traumatic events.

RESUMEN

BACKGROUND: Castleman disease is a rare lymphoproliferative disease of low malignant potential occurring in two forms, unicentric and multicentric. Surgery, chemotherapy, immunotherapy and radiation therapy have all been used to manage the disease. In this study, we evaluate whether the site of the lesions, that is, superficial or deep, influences the surgical outcome. METHODS: We retrospectively reviewed the records of 20 patients operated on for Castleman disease from 1994 to 2003, of whom 11 patients had superficial disease and 9 had deep lesions. The end-points of this study were survival and recurrence. RESULTS: Of the 20 patients, 19 had unicentric (cervical in 8, mediastinal in 5, retroperitoneal in 2, axillary in 2, hepatic in 1, and mesenteric in 1) and 1 had multicentric Castleman disease. Among 19 patients who had complete resection (18 with unicentric and 1 with multicentric disease), there has been no evidence of recurrence. CONCLUSION: Whether Castleman disease is superficial or deep has no effect on surgical outcome as long as resection is complete.
