RESUMEN

Context: For secondary hyperparathyroidism (SHPT), physicians prefer conservative treatments, and surgical intervention has proven to be the best solution for some patients. Among the surgical interventions, total parathyroidectomy plus autotransplantation (TPTX+AT), using the forearm, is the major effective treatment. TPTX+AT, in conjunction with transoral endoscopic thyroidectomy vestibular approach (TOETVA), includes many advantages. Objective: The study intended to evaluate the clinical value of performing an endoscopic total parathyroidectomy TPTX+AT in conjunction with TOETVA in treating SHPT and to summarize and share the clinical experience. Design: The research team performed a prospective controlled study. Setting: The study took place at the Zhongshan Boai Hospital affiliated with Southern Medical University in Zhong Shan, Guangdong, China. Participants: Participants were 97 SHPT patients who were admitted to the hospital between March 2020 and March 2022. Intervention: The intervention group included 47 SHPT patients who received endoscopic TPTX+AT combined with the TOETVA, and the control group included 50 SHPT patients who received routine TPTX+AT. Outcome Measures: The research team performed comparisons between the groups regarding: (1) operating conditions, including intraoperative blood loss, operating time, and number of parathyroid glands detected intraoperatively; (2) clinical efficacy, (3) postoperative complications, (4) parathyroid hormone (PTH) and calcium (Ca) levels, (5) psychological status using the Hamilton Anxiety (HAMA) and the Hamilton Depression Scale (HAMD), and (9) life quality using the 36-Item Short Form Health Survey (SF-36). Results: The intervention group had significantly longer operation times and significantly greater intraoperative blood loss than the control group did, but the intervention group had fewer complications, lower PTH and Ca levels, and a higher efficacy (P < .05). The intervention group also had a significantly better psychological state and prognostic quality of life than the control group did (P < .05). Conclusions: Endoscopic treatment of SHPT using TPTX+AT in combination with TOETVA can significantly relieve clinical symptoms and lower serum PTH and Ca levels. The results suggest that the operation is safe and effective.

RESUMEN

Approximately 10% to 30% of patients with classical Hodgkin lymphoma (cHL) develop relapsed or refractory (R/R) disease. Of those patients, 50% to 60% show long-term progression-free survival after standard salvage chemotherapy followed by high-dose chemotherapy (HDCT) and autologous stem cell transplant (ASCT). In the past decade, novel therapies have been developed, such as the CD30-directed antibody-drug conjugate brentuximab vedotin and immune checkpoint inhibitors, which have greatly extended the treatment possibilities for patients with R/R cHL. Several phase 1/2 clinical trials have shown promising results of these new drugs as monotherapy or in combination with chemotherapy, but unfortunately, very few randomized phase 3 trials have been performed in this setting, making it difficult to give evidence-based recommendations for optimal treatment sequencing. Two important goals for the improvement in the treatment of R/R cHL can be identified: (1) increasing long-term progression-free and overall survival by optimizing risk-adapted treatment and (2) decreasing toxicity in patients with a low risk of relapse of disease by evaluating the need for HDCT/ASCT in these patients. In this review, we discuss treatment options for patients with R/R cHL in different settings: patients with a first relapse, primary refractory disease, and in patients who are ineligible or unfit for ASCT. Results of clinical trials investigating novel therapies or strategies published over the past 5 years are summarized.

RESUMEN

The inflammatory response is an obstacle to success in both allogeneic and autologous islet transplantation. In autologous islet transplantation (AIT), however, the recipient is also the donor, permitting pretreatment of donor/recipient for a controlled duration prior to transplantation. We sought to exploit this feature of (AIT) by pretreating donor/recipients with chronic pancreatitis undergoing total pancreatectomy and autologous islet transplantation (TPAIT) to test the hypothesis that peri-transplant treatment with the FDA-approved anti-inflammatory hydroxychloroquine (HCQ) improves graft function. In this randomized placebo-controlled pilot clinical study, patients (n = 6) were treated with oral HCQ for 30 days prior to and 90 days after TPAIT. In vivo islet function was assessed via Mixed Meal Tolerance Testing before HCQ treatment, 6- and 12-months after surgery. In vitro islet bioenergetics were assessed at the time of transplantation via extracellular flux analysis of islet preparation samples from the clinical trial cohort and six additional patients (n = 12). Our study shows that HCQ did not alter clinical endpoints, but HCQ-treated patients showed greater spare respiratory capacity (SRC) compared to samples from control patients (P=0.028). Glycolytic metabolism of islet preparations directly correlated with stimulated C-peptide secretion both before and after TPAIT (P=0.01, R2=0.489 and P=0.03, R2=0.674, respectively), and predicted in vivo islet function better than mitochondrial metabolism of islet preps or islet equivalents infused. Overnight culture of islet preparations altered bioenergetic function, significantly decreasing SRC and maximal respiration (P<0.001). In conclusion, while HCQ did not alter clinical outcomes, it was associated with significantly increased SRC in islet preparations. Bioenergetic analyses of islet preparations suggests that culture should be avoided and that glycolysis may be a more sensitive indicator of in vivo islet function than current metrics, including islet oxygen consumption and islet equivalents infused.

RESUMEN

BACKGROUND: Synchronous multicentric osteosarcoma (SMOS) is a rare disease characterized by simultaneous multicentricity of intraosseous osteosarcoma without visceral involvement. SMOS, including a skull lesion, which occurs relatively rarely, and reconstruction using a frozen autograft after the excision of a lesion of SMOS has been infrequently reported previously. CASE PRESENTATION: We report an 18-year-old girl with SMOS, with lesions located in the left distal femur, right proximal humerus, and left occipital bone. Her major complaint was pain and swelling around the left knee joint. Asymptomatic lesions of the humerus and skull bone were detected on a systemic bone scan. No visceral organ metastasis was observed. A biopsy of the distal femoral lesion revealed osteosarcoma. Based on the histological findings, multiple bone lesions, and absence of visceral lesion, the clinical diagnosis of SMOS was made. After five courses of neoadjuvant chemotherapy with a regimen of doxorubicin and cisplatin, reconstruction using a tumor prosthesis following wide excision of the left distal femur was performed, and total necrosis was histologically observed in the retracted specimen. Following three cycles of adjuvant chemotherapy, tumor excision and reconstruction with a frozen autograft treated with liquid nitrogen was conducted for both lesions of the humerus and skull, rather than tumor prosthesis or synthetics, in order to retain a normal shoulder function, and to obtain a good cosmetic and functional outcome after treatment of the skull lesion. Further adjuvant chemotherapy could not be administered after the completion of the surgical treatment for all lesions because the adverse events due to chemotherapy were observed. At over 5 years after the diagnosis, she remains clinically disease-free. CONCLUSIONS: An early correct diagnosis, the proper management of chemotherapy, and surgical treatment for all lesions are essential for achieving a good clinical outcome, even in SMOS including a skull lesion. By performing reconstruction using a frozen autograft for a proximal humeral lesion and a skull lesion after confirming the good histological efficacy of neoadjuvant chemotherapy for the primary lesion, the excellent function of the shoulder joint and a good cosmetic outcome at the site of the skull lesion was acquired without complications or recurrence.

RESUMEN

BACKGROUND: Approximately half of patients with relapsed chemosensitive disease achieve robust responses with BEAM (BCNU, etoposide, cytarabine, and melphalan) and autologous stem cell rescue. The scarcity of comparative studies further limits alternative treatment protocols, such as the MITO/MEL (mitoxantrone, melphalan) protocol. PATIENTS AND METHODS: In this retrospective multicenter study, we compared the BEAM and MITO/MEL regimens used before autologous hematopoietic stem cell transplantation (ASCT) in terms of efficacy and side effects in patients with Hodgkin lymphoma. Data met international accreditation rules. Before ASCT, 108 patients received the MITO/MEL, and 34 patients received the BEAM. RESULTS: The median follow-up time was 36 months in the MITO/MEL group (range, 3-178) and 23 months in the BEAM group (range, 4-99). After ASCT, the 3-year expected overall survival and disease-free survival rates were 86.1% and 86.1% for the MITO/MEL group and 91.3% and 76.5% for the BEAM group, respectively. Although 50% of patients developed febrile neutropenia attacks in the MITO/MEL group, this rate was 91.1% in the BEAM group. The grade II and higher rates of hepatic, renal, gastrointestinal, and cardiac toxicities were similar in both groups. However, the rate of pulmonary toxicity was determined to be 1.9% in the MITO/MEL group and 29.4% in the BEAM group (P < .001). CONCLUSION: The MITO/MEL conditioning regimen seems to be as effective as the BEAM regimen but has better tolerability in terms of pulmonary toxicity and may be used as an alternative option if necessary, depending on the comorbidity status of the patient.

RESUMEN

Primary bone marrow diffuse large B cell lymphoma (DLBCL) is an independent pathologic type with a poor prognosis when treated with standard chemoimmunotherapy. Generally, rituximab-based high-dose chemotherapy regimens such as dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin (DA-EPOCH) can be administered to young patients, followed by autologous stem cell transplantation. For elderly patients, the rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP) regimen is well tolerated, but it is an insufficient induction therapy for this group. Herein, we reported an elderly patient diagnosed with primary bone marrow DLBCL, germinal center B-cell-like subtype. Considering tolerance, the R-CHOP regimen was administered. However, his disease progressed after two treatment cycles. Then, the rituximab, gemcitabine, dexamethasone, cisplatin, lenalidomide regimen was administered, but the patient still experienced disease progression. Subsequently, the histone deacetylase (HDAC) inhibitor chidamide and Bruton's tyrosine kinase (BTK) inhibitor ibrutinib were concurrently administered, and the patient achieved complete remission. We found that the response of primary bone marrow DLBCL to chemotherapy was poorer than that of de novo DLBCL. High-dose chemotherapy regimens such as DA-EPOCH should be administered to young patients in combination with rituximab. For elderly patients, new targeted drugs such as HDAC and BTK inhibitors appear to produce favorable outcomes.

RESUMEN

Late detection, compromised immune system, and chemotherapy resistance underlie the poor patient prognosis for pancreatic ductal adenocarcinoma (PDAC) patients, making it the 3rd leading cause of cancer-related deaths in the United States. Cooperation between the tumor cells and the immune system leads to the immune escape and eventual establishment of the tumor. For more than 20 years, sincere efforts have been made to intercept the tumor-immune crosstalk and identify the probable therapeutic targets for breaking self-tolerance toward tumor antigens. However, the success of these studies depends on detailed examination and understanding of tumor-immune cell interactions, not only in the primary tumor but also at distant systemic niches. Innate and adaptive arms of the immune system sculpt tumor immunogenicity, where they not only aid in providing an amenable environment for their survival but also act as a driver for tumor relapse at primary or distant organ sites. This review article highlights the key events associated with tumor-immune communication and associated immunosuppression at both local and systemic microenvironments in PDAC. Furthermore, we discuss the approaches and benefits of targeting both local and systemic immunosuppression for PDAC patients. The present articles integrate data from clinical and genetic mouse model studies to provide a widespread consensus on the role of local and systemic immunosuppression in undermining the anti-tumor immune responses against PDAC.

RESUMEN

BACKGROUND: Autologous monocyte-derived mRNA co-electroporated dendritic cells with mRNA encoding CD40 ligand (CD40L), CD70 and a constitutively activated TLR4 (caTLR4) (referred to as TriMixDC-MEL) have anti-tumor activity in advanced melanoma patients. We investigated the safety and activity of adjuvant TriMixDC-MEL in stage III/IV melanoma patients. MATERIALS AND METHODS: Forty-one patients were randomly assigned to treatment with TriMixDC-MEL (n = 21) and standard follow-up (n = 20). "Cross-over" was allowed at the time of non-salvageable recurrence. The primary endpoint was the percentage of patients alive and disease-free at 1-year. For a subset of patients, (formalin-fixed paraffin-embedded), tumor tissue samples were available for mRNA expression profiling and PD-L1 immunohistochemical staining. RESULTS: Baseline characteristics were well balanced. One-year after randomization, 71% of patients in the study arm were alive and free of disease compared to 35% in the control arm. After a median follow-up of 53 months (range 3-67), 23 patients experienced a non-salvageable melanoma recurrence (TriMixDC-Mel arm n = 9 and control arm n = 14).The median time to non-salvageable recurrence was superior in the TriMixDC-MEL arm (median 8 months (range 1-6) vs. not reached; log-rank p 0.044). TriMixDC-MEL-related adverse events (AE) consisted of transient local skin reactions, flu-like symptoms and post-infusion chills. No grade ≥ 3 AE's occurred. The mRNA expression profiling revealed four genes (STAT2, TPSAB1, CD9 and CSF2) as potential predictive biomarkers. CONCLUSION: TriMixDC-MEL id/iv as adjuvant therapy is tolerable and may improve the 1-year disease-free survival rate. Combination of optimized autologous monocyte-derived DC-formulations warrants further investigation in combination with currently approved adjuvant therapy options.

RESUMEN

Osteoarthritis (OA) is the most common joint condition and, with a burgeoning ageing population, is due to increase in prevalence. Beyond conventional medical and surgical interventions, there are an increasing number of 'alternative' therapies. These alternative therapies may have a limited evidence base and, for this reason, are often only afforded brief reference (or completely excluded) from current OA guidelines. Thus, the aim of this review was to synthesize the current evidence regarding autologous chondrocyte implantation (ACI), mesenchymal stem cell (MSC) therapy, platelet-rich plasma (PRP), vitamin D and other alternative therapies. The majority of studies were in knee OA or chondral defects. Matrix-assisted ACI has demonstrated exceedingly limited, symptomatic improvements in the treatment of cartilage defects of the knee and is not supported for the treatment of knee OA. There is some evidence to suggest symptomatic improvement with MSC injection in knee OA, with the suggestion of minimal structural improvement demonstrated on MRI and there are positive signals that PRP may also lead to symptomatic improvement, though variation in preparation makes inter-study comparison difficult. There is variability in findings with vitamin D supplementation in OA, and the only recommendation which can be made, at this time, is for replacement when vitamin D is deplete. Other alternative therapies reviewed have some evidence (though from small, poor-quality studies) to support improvement in symptoms and again there is often a wide variation in dosage and regimens. For all these therapeutic modalities, although controlled studies have been undertaken to evaluate effectiveness in OA, these have often been of small size, limited statistical power, uncertain blindness and using various methodologies. These deficiencies must leave the question as to whether they have been validated as effective therapies in OA (or chondral defects). The conclusions of this review are that all alternative interventions definitely require clinical trials with robust methodology, to assess their efficacy and safety in the treatment of OA beyond contextual and placebo effects.

RESUMEN

BACKGROUND: Since antiquity, humans have been trying to devise remedies to cure androgenetic alopecia (AGA). These efforts include use of oral and topical concoctions and hair transplant strategies. As AGA affects people of all colors and creed, there has been a continuous effort to find a magic bullet against AGA. Unfortunately, to date, all the strategies to negate AGA effects have limitations and thus require new treatment options. AIM: To evaluate the efficacy of use of stromal vascular fraction (SVF) in androgenetic alopecia patients. METHODS: Stromal vascular fraction was obtained by enzymatic digestion of autologous adipose tissue. The patients were divided into two groups, that is, platelet-rich plasma (PRP) group and SVF-PRP group. In PRP group, only PRP was injected, while in SVF-PRP group a mixture of PRP and SVF was injected in affected scalp areas. After two sessions (4 weeks apart), the patients in both groups were assessed and analyzed using various parameters. RESULTS: Mean hair density in PRP group was increased from 52.44 hair/cm2 to 63.72 hair/cm2 (21.51% increase); while in SVF-PRP group, it was 37.66 hair/cm2 before treatment and 57.11 hair/cm2 after SVF-PRP therapy (51.64% increase). Percentage reduction in pull test was more significant in SVF-PRP group (80.78 ± 5.84) as compared to PRP group (34.01 ± 22.44). The physician and patient assessment scores also indicated a significant improvement in SVF-PRP group. CONCLUSION: A combined SVF-PRP therapy reversed effects of AGA more efficiently as compared to PRP therapy alone.

RESUMEN

INTRODUCTION: In reconstructive surgery, fat volume augmentation is often necessary for esthetic or functional reasons. As an alternative to synthetic and xenogeneic materials, autologous fat grafting (AFG) based on liposuction is gaining popularity, yet successful transplantation and long-term volume maintenance are difficult. Standard tumescent solution formulations neglect adipocyte and stromal vascular fraction (SVF) cell survival during extraction, as well as SVF differentiation into adipocytes thereafter, all of which are crucial for the success of AFG. Here we hypothesized that addition of ascorbic acid (AA) to the tumescent solution could prevent liposuction-induced cell damage. MATERIALS AND METHODS: The effect of 0.1 mmol/L AA in tumescent solution was investigated in a previously described ex vivo model of AFG. Briefly, excision fat was infiltrated with tumescent solution, with or without AA, and incubated for 20 minutes at 37°C. Hand-assisted liposuction was then performed with a blunt cannula. Total cell viability, clonogenicity, and differentiation capacity of the SVF cells were assessed. RESULTS: With AA, 10.3% more cells and in particular 14.9% more adipocytes survived liposuction. Clonogenicity, adipocyte and osteoblast differentiation by SVF cells remained unchanged. CONCLUSIONS: Addition of AA successfully improved survival of adipocytes during liposuction without affecting SVF growth and differentiation. This study therefore identified a useful supplement to the tumescent solution which may lead to improving AFG success.

RESUMEN

BACKGROUND: Scarring is a distressing outcome of acne, as it causes cosmetic and psychological problems to the patients. Unfortunately no single treatment is satisfactory; instead, employing multiple modalities may have better outcome. Autologous adipose tissue-derived adult stem cells (AT-ASCs) and their secretory factors can stimulate collagen synthesis; angiogenesis and migration of fibroblasts thus regenerate damaged tissues. Also, conventional treatments for acne scarring, such as lasers and topical regimens, induce new collagen synthesis via activation of dermal fibroblasts or growth factors. The aim of the study was to verify the effectiveness of AT-ASCs for the treatment of acne scarring vs. the fractional carbon dioxide laser (FxCR). SUBJECTS AND METHODS: Split face comparative study included 10 adult patients with post-acne scars on both sides of the face. One side received AT-ASCs single injection while the other received three sessions of FxCR. Scars were then assessed using the global scoring system Goodman and Baron, scar area percent using NIH ImageJ software and functional assessment by measuring the transepidermal water loss (TEWL) and skin hydration. Both sides were followed for three months. RESULTS: A significant improvement in the degree of scar severity, scar area percent, skin hydration, and TEWL after 3 months of treatment on both sides of the face with insignificant differences between both treatment modalities, provided that AT-ASCs treatment was employed once vs. three sessions of FxCR. CONCLUSION: One injection of AT-ASCs is as effective as three sessions of FxCR in the treatment of atrophic acne scars.

RESUMEN

BACKGROUND: Subgroups of patients with relapsed or refractory (R/R) chronic lymphocytic leukemia (CLL) exhibit suboptimal outcomes after standard therapies, including oral kinase inhibitors. We and others have previously reported on safety and efficacy of autologous CD19-targeted CAR T-cells for these patients; here we report safety and long-term follow-up of CAR T-cell therapy with or without conditioning chemotherapy for patients with R/R CLL and indolent B-cell non-Hodgkin lymphoma (B-NHL). METHODS: We conducted a phase 1 clinical trial investigating CD19-targeted CAR T-cells incorporating a CD28 costimulatory domain (19-28z). Seventeen of 20 patients received conditioning chemotherapy prior to CAR T-cell infusion. Five patients with CLL received ibrutinib at the time of autologous T-cell collection and/or CAR T-cell administration. RESULTS: This analysis included 16 patients with R/R CLL and 4 patients with R/R indolent B-NHL. Cytokine release syndrome (CRS) was observed in all 20 patients but grades 3 and 4 CRS and neurological events were uncommon (10% for each). Ex vivo expansion of T-cells and proportions of CD4+/CD8+ CAR T-cells with CD62L+CD127+ immunophenotype were significantly greater in patients on ibrutinib at leukapheresis. Three of 12 evaluable CLL patients receiving conditioning chemotherapy achieved CR (two had minimal residual disease-negative CR). All patients achieving CR remained progression-free at median follow-up of 53 months. CONCLUSION: Conditioning chemotherapy and 19-28z CAR T-cells were acceptably tolerated across investigated dose levels in heavily pretreated patients with R/R CLL and indolent B-NHL, and a subgroup of patients achieved durable CR. Ibrutinib therapy may modulate autologous T-cell phenotype. TRIAL REGISTRATION: ClinicalTrials.gov NCT00466531. FUNDING: Juno Therapeutics.

RESUMEN

INTRODUCTION: Primary plasma cell leukemia (PPCL) is one of the most aggressive hematological malignancies. The prognosis of PPCL patients remains poor, although some improvements have been made in recent years. Areas covered: In this review recent clinical and biological advances in PPCL are reported. Some recommendations for the practical management of these patients are provided, with a particular focus on the role of novel agents and transplant procedures. A brief description of the currently ongoing clinical trials with new drugs is also enclosed. Expert opinion: PPCL still represents a difficult challenge for all hematologists. Here the authors provide a personal view on how the current, generally unsatisfactory results in this neoplastic disorder could be improved. In particular, dedicated studies exploring alternative therapies are necessary and eagerly awaited. Such studies should possibly be based on new biological information that could be of help in identifying novel genetic biomarkers for risk stratification and new actionable molecular targets.

RESUMEN

PURPOSE: Increased complications following failed hypospadias repairs suggest that impaired wound healing is a contributing factor. We used perioperative hyperbaric oxygen therapy to promote wound healing determined by graft take in staged tubularized autograft reoperations using oral graft. MATERIALS AND METHODS: Hyperbaric oxygen therapy was recommended for patients with 3 or more failed hypospadias repairs, comprising 20 preoperative and 10 postoperative sessions. All patients underwent reoperative staged tubularized autograft repair using oral mucosa. Graft lengths and widths were measured at grafting and again at the second stage, from which graft area was calculated. The primary outcomes were percent graft contracture and graft failure, defined as contracture 50% or greater. Patients who received hyperbaric oxygen therapy were compared to other patients who underwent reoperative staged tubularized autograft who did not receive therapy. RESULTS: Among 57 patients 32 received hyperbaric oxygen therapy and 25 did not as they had fewer than 3 prior repairs, or were not able to receive treatment due to insurance issues or lack of local availability. Grafts were healthier in those receiving hyperbaric oxygen therapy, with significantly less percent area contracture (9% vs 26%, p=0.04) and graft failure (6% vs 28%, p=0.03) compared to those not receiving therapy, although treated patients had significantly more prior failed hypospadias repairs. CONCLUSIONS: Hyperbaric oxygen therapy improved graft take in hypospadias reoperations. This observation also calls attention to wound healing as another variable to consider in hypospadias surgery.

RESUMEN

BACKGROUND: Noncultured epidermal cell suspension (NCES) is an effective surgical modality for stable vitiligo which involves transplantation of the basal layer of epidermal cells onto the dermabraded vitiliginous patch. Platelet-rich plasma (PRP) has growth factors which may stimulate melanocyte migration and proliferation of keratinocytes and fibroblasts. The objective of this study was to compare the extent of repigmentation achieved by transplantation of NCES suspended in PRP with that of NCES suspended in phosphate buffered saline (PBS). METHODS: Twenty-one patients of stable vitiligo with at least two lesions of comparable size were included. The two vitiligo patches were randomized to receive NCES suspended in PRP or PBS. Postoperatively after 1 week, patients were given heliotherapy for 15 minutes daily. RESULTS: At 6 months follow-up, mean repigmentation by area method in PRP arm was 75.6 ± 30% SD and in non-PRP arm was 65 ± 34% SD (P = 0.0036). Patient satisfaction by visual analogue scale at 6 months also showed better results in PRP arm (P = 0.001). Assessment by three independent observers showed better repigmentation in PRP side both at 3 and 6 months. CONCLUSIONS: Suspending NCES in PRP can result in significantly greater mean repigmentation and patient satisfaction than suspending in PBS.

RESUMEN

BACKGROUND: Salvia miltiorrhiza (SM) is an herb used in Chinese medicine formulations for promoting blood circulation and minimizing vascular stasis. It has been successfully utilized in treating cardiovascular diseases, such as atherosclerosis, thromboembolism, and angina. OBJECTIVES: The authors sought to study the effect of SM injections in autologous fat grafting to the breast. METHODS: Fifteen women who elected to undergo breast augmentation with autologous fat grafting were included in this study. Of these, 10 were given intravenous infusions of SM for 4 weeks perioperatively, and the remaining 5 did not receive herbal infusion. The increase in breast volume after fat grafting was measured in both the groups using a three-dimensional scanner. Breast tissue specimens were harvested just before the second fat injection procedure and were analyzed by the immunofluorescence staining test. RESULTS: All of the patients showed improvement in breast volume after fat grafting. The fat graft retention rate in the SM group was 60.06 ± 16.12%, whereas that in the non-SM group was 34.04 ± 11.15%. In addition, the SMG showed good breast morphology and absence of cyst formation. CONCLUSIONS: SM has the potential to increase the retention rate of fat grafts in breast augmentation.

RESUMEN

Background: Vitiligo is an acquired disfiguring common depigmented skin disease. Objectives: This study aimed to compare the clinical efficacy and safety of suction blistering graft, mini punch and hair follicle techniques in treatment of patients with stable vitiligo. Methods: Thirty patients with stable vitiligo were included. Patients were divided into 3 groups, in group (A) 10 patient underwent suction blistering technique, in group (B) 10 patients underwent mini punch technique and in group (C) 10 patients underwent hair follicle technique. Then all patients in the three techniques were subjected to narrow-band ultraviolet B (NB-UVB) phototherapy for 3 months. All patients were assessed by determining the percentage of repigmentation and Dermatology Life Quality Index (DLQI) before and 3 months after the operation. Results: The percentage of repigmentation of vitiligo in suction blister technique was significantly higher than both mini punch and hair follicle techniques (p value .001 and .0001 respectively). There was a statistically significant difference between the three techniques regarding DLQI score after operation (p value = .0001). Conclusion: This study concluded that suction blistering technique is more effective and safe than mini punch technique and hair follicle technique in treatment of stable vitiligo.

RESUMEN

BACKGROUND/AIM: Polaprezinc suspension in sodium alginate (PZ-AG) reduces the incidence and severity of oral mucositis in adult patients receiving radiotherapy or high-dose chemotherapy. In the present study, the prophylactic effect of PZ-AG against oral mucositis was assessed in pediatric patients with hematological malignancies receiving high-dose chemotherapy followed by hematopoietic stem cell transplantation (HSCT). PATIENTS AND METHODS: Data of 16 children who underwent HSCT during a period between January 2010 and December 2017 were obtained from medical records and they were retrospectively analyzed. Oral mucositis was evaluated by the WHO scale. RESULTS: Six (37.5%) of 16 children refused to take PZ-AG in a preliminary assessment and they were pretreated with azulene gargle. The remaining 10 (62.5%) patients were pretreated with PZ-AG for prevention of oral mucositis. Grade≥ 3 oral mucositis occurred in 5 (83.3%) of 6 patients receiving azulene gargle, but in 2 (20%) patients who took PZ-AG (p=0.035). The prevalence for the use of opioid analgesics was also significantly lower (30% vs. 100%, p=0.011), while the average duration of total parenteral nutrition use was significantly shorter (11.1 days vs. 24.3 days, p=0.016), in PZ-AG group than in azulene group. On the other hand, PZ-AG had no significant influence on the incidence of other adverse events, mean time to engraftment, or overall survival. CONCLUSION: PZ-AG was found to be highly effective in preventing oral mucositis in pediatric patients with hematological malignancies receiving high-dose chemotherapy followed by HSCT, as in adult patients.
