Synergistic effect of Silver-Nanodiamond composite as an efficient antibacterial agent against E. coli and S. aureus.

Bacterial antimicrobial resistance (BAMR) seems to pose the greatest threat to public health, food safety, and agriculture in this century. The development of novel efficient antimicrobial agents to combat bacterial infections has become a global issue. Silver nanoparticles (Ag NPs) appeared as a feasible alternative to antibiotics. However, Ag NPs face cost, toxicity, and aggregation issues which limit their antibacterial activity. This work aims to stabilize Ag NPs with enhanced antimicrobial activity at comparatively lower Ag concentrations to prevent bacterial infections. For this purpose, the Ag core was covered with nanodiamonds (NDs). Ag-NDs composite have been synthesized by microplasma technique. TEM analysis confirmed the presence of both Ag and NDs in the Ag-NDs composite. A particle size (∼19 nm) was reported for Ag-NDs at the highest concentration as compared to Ag NPs (∼3 nm). The conduction band of the diamond acted as an extremely strong reducing agent for Ag NPs. The large surface area of NDs stabilized the Ag NPs. A redshift (∼400 nm-406 nm) in UV-visible spectra of the Ag-NDs composite indicated the formation of bigger-sized Ag NPs after incorporating NDs. XRD and LIBS analysis verified the increase in intensity of Ag-NPs by increasing ND concentration. The presence of functional groups including OH, CH, and Ag/Ag2O was confirmed by FTIR. Bacterial inhibition growth appeared to be a dose-dependent process. The minimum inhibition concentration value of Ag-NDs composite at the highest NDs concentration against E. coli (∼ 0.69 µg/ml) and S. aureus (∼44 µg/ml). This is the first study to report the smallest MIC for E. coli (<1 µg/ml). Ag-ND composites emerged to be more efficient than Ag NPs and preferred to be used against BAMR. The enhanced antibacterial activity of the Ag-NDs composite makes it a potential candidate for antibiotics, food products, and pesticides.

Development and bioassessment of high nutria-omega 5 cookies through animal modeling.

The food industry generates a diverse range of waste byproducts during fruit processing, which can be repurposed to create functional foods and other valuable commodities. In this particular study, leftover agro-waste from pomegranate juice was valorized to obtain pomegranate seed oil (PSO), while utilizing sunflower oilseed cake to produce sunflower meal protein concentrate (SMPC). These two extracted components were then combined as ingredients to produce High Nutria Omega 5 (HNO5) cookies. To ensure the quality and viability of pomegranate seed oil, a comprehensive set of laboratory analytical procedures were employed to evaluate its characteristics. Subsequently, different ratios of pomegranate seed oil and sunflower meal protein concentrate were utilized to develop the HNO5 cookie products. These cookies underwent thorough sensory, physicochemical, storage, and proximate evaluations as well as efficacy studies to assess their overall nutritional quality and shelf-life properties. As compared to the control feed, the findings of the renal and liver functional tests indicated a favorable effect on ALT, AST, ALP, serum urea, creatinine, albumin, globulins, total proteins, and A/G ratio. The results revealed that PSO and SMPC cookies containing 15% PSO and 15% SMPC exhibited stability in numerous physicochemical and sensory assessments. The punicic acid in HNO5 cookies significantly reduced the effects of starvation in rats and progressively improved several metabolic processes and overall health profiles. Graphical Abstract.

An assessment of publishing practices and barriers faced by medical students to conduct research: A cross-sectional study from Pakistan.

Background: Pakistan being a low- and middle-income country, its institutes are substantially deficient in scientific and technological aspects and share limited research contributions to the world repositories. Therefore, there is a rising concern to reflect on the history and status of publishing attitudes among medical students in Pakistan and to highlight and address the barriers that they are facing. Methods: A study was conducted aiming to determine the experience, motivation, and attitude of medical students in regarding publishing practices throughout Pakistan in several medical colleges. A multivariable logistic regression model was used to find the independent predictors of students publishing a research article. Forward selection was used to arrive at the final stepwise logistic regression. Odds ratio (OR) and 95% confidence interval (CI) were calculated. p < 0.05 was considered significant for all statistical tests. Results: From a sample size of 1225 participants, only 6.6% of students had published an article in our study. Of these, 59% were males and 31.3% were in final year. Males were more likely to publish articles than females (OR = 2.69, 95% CI: 1.37-5.26) and final-year students were more likely to publish articles than first-year students (OR = 7.48, 95% CI: 1.34-41.81). Students that had the knowledge that performing research is the way through which they will be judged for jobs had significantly higher odds of getting an article published (OR = 16.21, 95% CI: 3.65-71.88). Additionally, students who had been taught how to write a paper and those who knew the process of submitting an article were more likely to get published than the others. Conclusion: Our study has successfully highlighted the status of publishing among medical students in Pakistan. Our findings serve as an eye opener and call to action for authorities to address the grievances of students in terms of barriers, lack of mentorship, and lack of research teaching. We hope our findings can guide a strong policy change to facilitate the next generation of passionate researchers.

Burnout in health care workers during the fourth wave of COVID-19: A cross sectional study from Pakistan.

Objective: To assess the burnout among the healthcare workers during the fourth wave of COVID-19. Methods: In this cross-sectional study, burn out was measured in health care professionals using the MBI scale inventory during the fourth wave of COVID-19. Age, gender, marital status, having children, hospital, job type, experience, and workload, as well as the severity of burnout in each subscale, were all measured. We used the chi-square test to detect the difference between the level of burnout and other demographic variables, and a multiple logistic regression test was used to define the predicted correlation between the high level of burnout and the risk factors. Odds ratios and corresponding 95% confidence intervals (CI) were reported. A p-value of less than 0.05 indicated a statistically significant outcome. Results: Out of 776 healthcare workers who participated in our study, 468 (63.2%), 161 (21.7%) and 112 (15.1%) participants experienced low, moderate and high levels of emotional exhaustion, respectively. For the depersonalization subscale, 358 (48.3%), 188 (25.4%) and 195 (26.3%) people suffered from low, moderate, and high levels of depersonalization, respectively while 649 (87.6%), 40 (5.4%) and 52 (7.0%) respondents had low, moderate and high levels in the personal accomplishment subscale, respectively. Conclusion: During the fourth wave of COVID-19, the healthcare workers reported increased level of burnout overall possibly due to the long term physical and mental impacts that the pandemic has had over the time. Moreover, healthcare workers in Pakistan were more prone to burnout as compared to other countries.

Raman spectroscopic characterization of selenium N-heterocyclic carbene compounds.

In this study, Raman spectroscopy is employed to analyze and characterize two salts (N-heterocyclic carbene) and their respective selenium N-heterocyclic carbene compounds. The features observed as differences among Raman spectral data of two different N-heterocyclic carbene salts are called Salt-I and Salt-II and their respective Se compounds, called Compound-I & Compound-II, are used to confirm the formation covalent bond between Se atom carbon atom of carbene. Enhancement in peak intensities and shifting of peak positions is directly related with compound formation. Raman spectral data provide a detail information about bond formation, chemical and structural differences between salts and compounds. The observed Raman spectral features of both salts and compounds are in consistent with computationally calculated Raman spectral features. Raman spectral features of each salt and its respective compound was further analyzed with principal component analysis, which was found helpful for differentiating each salt from its respective compound.

Potential bioactive coating system for high-performance absorbable magnesium bone implants.

Magnesium alloys are considered the most suitable absorbable metals for bone fracture fixation implants. The main challenge in absorbable magnesium alloys is their high corrosion/degradation rate that needs to be controlled. Various coatings have been applied to magnesium alloys to slow down their corrosion rates to match their corrosion rate to the regeneration rate of the bone fracture. In this review, a bioactive coating is proposed to slow down the corrosion rate of magnesium alloys and accelerate the bone fracture healing process. The main aim of the bioactive coatings is to enhance the direct attachment of living tissues and thereby facilitate osteoconduction. Hydroxyapatite, collagen type I, recombinant human bone morphogenetic proteins 2, simvastatin, zoledronate, and strontium are six bioactive agents that show high potential for developing a bioactive coating system for high-performance absorbable magnesium bone implants. In addition to coating, the substrate itself can be made bioactive by alloying magnesium with calcium, zinc, copper, and manganese that were found to promote bone regeneration.

Urethral luminal epithelia are castration-insensitive cells of the proximal prostate.

BACKGROUND: Castration-insensitive epithelial progenitors capable of regenerating the prostate have been proposed to be concentrated in the proximal region based on facultative assays. Functional characterization of prostate epithelial populations isolated with individual cell surface markers has failed to provide a consensus on the anatomical and transcriptional identity of proximal prostate progenitors. METHODS: Here, we use single-cell RNA sequencing to obtain a complete transcriptomic profile of all epithelial cells in the mouse prostate and urethra to objectively identify cellular subtypes. Pan-transcriptomic comparison to human prostate cell types identified a mouse equivalent of human urethral luminal cells, which highly expressed putative prostate progenitor markers. Validation of the urethral luminal cell cluster was performed using immunostaining and flow cytometry. RESULTS: Our data reveal that previously identified facultative progenitors marked by Trop2, Sca-1, KRT4, and PSCA are actually luminal epithelial cells of the urethra that extend into the proximal region of the prostate, and are resistant to castration-induced androgen deprivation. Mouse urethral luminal cells were identified to be the equivalent of previously identified human club and hillock cells that similarly extend into proximal prostate ducts. Benign prostatic hyperplasia (BPH) has long been considered an "embryonic reawakening," but the cellular origin of the hyperplastic growth concentrated in the periurethral region is unclear. We demonstrate an increase in urethral luminal cells within glandular nodules from BPH patients. Urethral luminal cells are further increased in patients treated with a 5-α reductase inhibitor. CONCLUSIONS: Our data demonstrate that cells of the proximal prostate that express putative progenitor markers, and are enriched by castration in the proximal prostate, are urethral luminal cells and that these cells may play an important role in the etiology of human BPH.

Prune belly syndrome in surviving males can be caused by Hemizygous missense mutations in the X-linked Filamin A gene.

BACKGROUND: Prune belly syndrome (PBS) is a rare, multi-system congenital myopathy primarily affecting males that is poorly described genetically. Phenotypically, its morbidity spans from mild to lethal, however, all isolated PBS cases manifest three cardinal pathological features: 1) wrinkled flaccid ventral abdominal wall with skeletal muscle deficiency, 2) urinary tract dilation with poorly contractile smooth muscle, and 3) intra-abdominal undescended testes. Despite evidence for a genetic basis, previously reported PBS autosomal candidate genes only account for one consanguineous family and single cases. METHODS: We performed whole exome sequencing (WES) of two maternal adult half-brothers with syndromic PBS (PBS + Otopalatodigital spectrum disorder [OPDSD]) and two unrelated sporadic individuals with isolated PBS and further functionally validated the identified mutations. RESULTS: We identified three unreported hemizygous missense point mutations in the X-chromosome gene Filamin A (FLNA) (c.4952 C > T (p.A1448V), c.6727C > T (p.C2160R), c.5966 G > A (p.G2236E)) in two related cases and two unrelated sporadic individuals. Two of the three PBS mutations map to the highly regulatory, stretch-sensing Ig19-21 region of FLNA and enhance binding to intracellular tails of the transmembrane receptor ß-integrin 1 (ITGß1). CONCLUSIONS: FLNA is a regulatory actin-crosslinking protein that functions in smooth muscle cells as a mechanosensing molecular scaffold, transmitting force signals from the actin-myosin motor units and cytoskeleton via binding partners to the extracellular matrix. This is the first evidence for an X-linked cause of PBS in multiple unrelated individuals and expands the phenotypic spectrum associated with FLNA in males surviving even into adulthood.

Phenotypic severity scoring system and categorisation for prune belly syndrome: application to a pilot cohort of 50 living patients.

OBJECTIVE: To design a novel system of scoring prune belly syndrome (PBS) phenotypic severity at any presenting age and apply it to a large pilot cohort. PATIENTS AND METHODS: From 2000 to 2017, patients with PBS were recruited to our prospective PBS study and medical records were cross-sectionally analysed, generating individualised RUBACE scores. We designed the pragmatic RUBACE-scoring system based on six sub-scores (R: renal, U: ureter, B: bladder/outlet, A: abdominal wall, C: cryptorchidism, E: extra-genitourinary, generating the acronym RUBACE), yielding a potential summed score of 0-31. The 'E' score was used to segregate syndromic PBS and PBS-plus variants. The cohort was scored per classic Woodard criteria and RUBACE scores compared to Woodard category. RESULTS: In all, 48 males and two females had a mean (range) RUBACE score of 13.8 (8-25) at a mean age of 7.3 years. Segregated by phenotypic categories, there were 39 isolated PBS (76%), six syndromic PBS (12%) and five PBS-plus (10%) cases. The mean RUBACE scores for Woodard categories 1, 2, and 3 were 20.5 (eight patients), 13.8 (25), and 10.6 (17), respectively (P < 0.001). CONCLUSIONS: RUBACE is a practical, organ/system level, phenotyping tool designed to grade PBS severity and categorise patients into isolated PBS, syndromic PBS, and PBS-plus groups. This standardised system will facilitate genotype-phenotype correlations and future prospective multicentre studies assessing medical and surgical treatment outcomes.

Copy number variations in a population with prune belly syndrome.

Prune Belly Syndrome (PBS) is a congenital multisystem myopathy with mild to lethal severity. While of uncertain etiology, 95% male predominance and familial occurrence suggest a genetic basis. As copy number variations (CNVs) can cause unexplained genetic disorders, we tested for novel CNVs in a large PBS population. We genotyped 21 unrelated PBS patients by high-resolution array comparative genomic hybridization (aCGH) and phenotyped using a novel PBS severity scoring system. Available parents were screened for detected CNV via quantitative PCR (qPCR). We additionally screened for recurrence of identified novel candidate CNVs on 106 PBS probands by qPCR. We identified 10 CNVs in 8 of 21 PBS patients tested (38%). Testing confirmed inheritance from an unaffected biological parent in six patients; parental samples were unavailable in two probands. One candidate CNV includes duplication of the X-chromosome AGTR2 gene, known to function in urinary tract development. Subsequent screening of the larger PBS cohort did not identify any recurrent CNVs. Presence of CNV did not correlate with PBS severity scoring. CNVs were uncommon in this large PBS population, but analysis of identified variants may inform disease pathogenesis and reveal targets for therapeutic intervention for this rare, severe disorder.

Enhancement of the Mechanical Properties of Hydroxyapatite/Sulphonated Poly Ether Ether Ketone Treated Layer for Orthopaedic and Dental Implant Application.

The mechanical properties of coated layers are one of the important factors for the long-term success of orthopeadic and dental implants. In this study, the mechanical properties of the porous coated layer were examined via scratch and nanoindentation tests. The effect of compression load on the porous coated layer of sulphonated poly ether ether ketone/Hydroxyapatite was studied to determine whether it changes its mechanical properties. The water contact angle and surface roughness of the compressed coated layer were also measured. The results showed a significant increase in elastic modulus, with mean values ranging from 0.464 GPa to 1.199 GPa (p<0.05). The average scratch hardness also increased significantly from 69.9 MPa to 95.7 MPa after compression, but the surface roughness and wettability decreased significantly (p<0.05). Simple compression enhanced the mechanical properties of the sulphonated poly ether ether ketone/hydroxyapatite coated layer, and the desired mechanical properties for orthopaedic and dental implant application can be achieved.

Nonrhabdomyosarcomatous abdominopelvic sarcomas: Analysis of prognostic factors.

BACKGROUND: Data concerning treatment outcome and prognostic factors in sarcomas of abdomen and pelvis are sparse in literature. METHODS AND RESULTS: Of 696 patients with nonrhabdomyosarcomatous soft tissue sarcoma registered at our center between June 2003 and December 2012, 112 (16%) patients of sarcomas arising from abdomen and pelvis were identified, of which 88 patients were analyzed for treatment outcome and prognostic factors. The median age was 40 years (range: 1-78 years) with a male: female ratio of 0.7:1. Twenty-one (24%) patients were metastatic at baseline. The most common tumor sites were retroperitoneum in 70% patients and abdominal wall in 18% patients. Leiomyosarcoma was the most common histological subtype in 36% patients followed by liposarcoma in 17% patients. Thirty-five (40%) patients had Grade III tumors. Forty-six (52%) patients underwent surgical resection. At a median follow-up of 43 months (range: 2-94 months), the 5-year event-free survival (EFS) and overall survival (OS) were 35% and 42%, with a median of 22 months and 43 months, respectively. Multivariate analysis identified male gender (P - 0.03, hazard ratio [HR] - 0.46, 95% confidence interval [CI] - 0.23-0.92), baseline metastatic disease (P - 0.01, HR - 2.98, 95% CI - 1.27-6.98) and Grade III tumors (P - 0.02, HR - 1.84, 95% CI - 1.08-3.13) as factors associated with poor EFS, whereas baseline metastatic disease (P < 0.001, HR - 5.45, 95% CI - 2.31-12.87) and unresectability (P - 0.01, HR - 2.72, 95% CI - 1.27-5.83) were associated with poor OS. CONCLUSION: This is a single-institutional study of patients with abdominopelvic sarcomas where gender was identified as a new factor affecting survival apart from baseline presentation, histologic grade, and surgical resection.

Preparation Methods for Improving PEEK's Bioactivity for Orthopedic and Dental Application: A Review.

There is an increased interest in the use of polyether ether ketone (PEEK) for orthopedic and dental implant applications due to its elastic modulus close to that of bone, biocompatibility, and its radiolucent properties. However, PEEK is still categorized as bioinert due to its low integration with surrounding tissues. Many studies have reported on methods to increase the bioactivity of PEEK, but there is still one-preparation method for preparing bioactive PEEK implant where the produced implant with desirable mechanical and bioactivity properties is required. The aim of this review is to present the progress of the preparation methods for improvement of the bioactivity of PEEK and to discuss the strengths and weaknesses of the existing methods.

Functionally graded polymeric materials: A brif review of current fabrication methods and introduction of a novel fabrication method.

The present work reviews the current fabrication methods of the functionally graded polymeric material (FGPM) and introduces a novel fabrication method that is versatile in applications as compared to those of existing used methods. For the first time electrophoresis was used to control the distribution of the tetracycline hydrochloride (TC) in a film made of polylactic acid (PLA), aiming to induce antimicrobial effect on the film prepared. The elemental analysis on the film surface showed that by employing electrophoresis force, higher amount of TC was detected near the top surface of the film. Results also showed that the FGPM samples with higher percentage of the TC on the film surface were highly effective to minimize the growth of Escherichia coli. These findings are useful and important to improve dispersion quality of the particles in the composite material and further enhance its antibacterial property.

p19(Arf) limits primary vitreous cell proliferation driven by PDGF-B.

Arf encodes an important tumor suppressor, p19(Arf), which also plays a critical role to control hyperplasia in the primary vitreous during mouse eye development. In the absence of Arf, mice are born blind and display a phenotype closely mimicking severe forms of the human eye disease, persistent hyperplastic primary vitreous (PHPV). In this report, we characterize p19(Arf) expression in perivascular cells that normally populate the primary vitreous and express the Arf promoter. Using a new ex vivo model, we show that these cells respond to exogenous Tgfß, despite being isolated at a time when Tgfß has already turned on the Arf promoter. Treatment of the cells with PDGF-B ligand doubles the population of cells in S-phase and ectopic expression of Arf blunts that effect. We show this effect is mediated through Pdgfrß as expression of Arf represses expression of Pdgfrß mRNA and protein to approximately 60%. p53 is not required for Arf-dependent blockade of PDGF-B driven proliferation and repression of Pdgfrß protein as ectopic expression of Arf is still able to inhibit the 2-fold increase in the S-phase fraction of cells upon treatment with PDGF-B. Finally, induction of mature miR-34a, a microRNA previously identified to be regulated by p19(Arf) does not depend on p53 while the expression of the primary transcript does require p53. These data corroborate that, as in vivo, p19(Arf) functions to inhibit PDGF-B driven proliferation ex vivo.

Enhancer Analysis Unveils Genetic Interactions between TLX and SOX2 in Neural Stem Cells and In Vivo Reprogramming.

The orphan nuclear receptor TLX is a master regulator of postnatal neural stem cell (NSC) self-renewal and neurogenesis; however, it remains unclear how TLX expression is precisely regulated in these tissue-specific stem cells. Here, we show that a highly conserved cis-element within the Tlx locus functions to drive gene expression in NSCs. We demonstrate that the transcription factors SOX2 and MYT1 specifically interact with this genomic element to directly regulate Tlx enhancer activity in vivo. Knockdown experiments further reveal that SOX2 dominantly controls endogenous expression of TLX, whereas MYT1 only plays a modulatory role. Importantly, TLX is essential for SOX2-mediated in vivo reprogramming of astrocytes and itself is also sufficient to induce neurogenesis in the adult striatum. Together, these findings unveil functional genetic interactions among transcription factors that are critical to NSCs and in vivo cell reprogramming.

Clinicopathological and treatment analysis of 13 extragastrointestinal stromal tumors of mesentery and retroperitoneum.

BACKGROUND: Extragastrointestinal stromal tumors (EGISTs) are extremely rare mesenchymal tumors histologically and immunophenotypically similar to GI stromal tumors (GISTs). The aim of this study was to analyze the clinicopathological factors and treatment outcome in 13 patients with EGISTs treated at a tertiary care center. METHODS: Of 109 patients with GISTs treated at our center between April 2002 and December 2012, 13 patients with EGISTs were analyzed for clinicopathological factors and treatment outcome. RESULTS: Mean age was 45.8 (range 30-61) years, and females constituted 62% with a male:female ratio of 0.6:1. The most common tumor sites were mesentery in 10 patients and retroperitoneum in 3 patients. Mean tumor size was 11.7 (range 5-18) cm. Four (31%) patients were metastatic at presentation, the most common site of metastases being the liver in 3 (75%) patients. Lymph node enlargement was seen in 2 patients. Surgery was performed in 8 (62%) patients, 7 with localized disease, and 1 with metastatic disease. R0 resection was achieved in 3 (38%) patients. Five (71%) patients were considered as high-risk. Recurrences were seen in 3 patients (patient 3, 5 and 13) with localized disease after surgical resection, at 18, 7 and 137 months, respectively. At the last follow up, 7 patients were alive and 6 died of disease progression. The median overall survival was 34 (7-148) months. CONCLUSIONS: EGISTs present at a younger age in the developing than in the developed countries. Females are more commonly affected than males. Lymph node metastases may be commonly present.

Advanced gastrointestinal stromal tumors: 10-years experience from a tertiary care centre.

BACKGROUND: Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the gastrointestinal tract. We aimed to study the pattern of presentation and treatment outcome of advanced GIST patients seen by us in a 10- year period. METHODS: Medical records of GIST patients seen between years 2002-2012 were retrieved from institute as well as database maintained by authors. Patient included in this analysis had metastatic disease and unresectable and/or residual disease after surgery. RESULTS: During the study period 62 patients fulfilled the inclusion criteria but 6 were lost to follow up before treatment and hence 56 patients were analysed. Median age was 45.5 years (range 17-70 years) with a male female ratio of 2:1. Thirty eight (67%) patients had metastatic disease whereas 32% patients had unresectable or incompletely resected disease. The most common primary site was small intestine in 24 (42.8%) which was followed by stomach in 11 (19.6%) patients. The most common site of metastases was liver in 27 (48%) patients. Median tumor size was 12 cm (range 4-50 cm). Thirty two (57%) patients had mitotic counts of > 5/50 HPF. All patients received imatinib. The most common response seen with imatinib was stable disease achieved in 29 (52%) patients. Imatinib was well tolerated by all patients without any drug discontinuation. The 5-year EFS and OS were 35% and 49%, respectively at a median follow up of 55 months. None of the patient or tumor factors were found to have prognostic significance in univariate survival analysis. CONCLUSIONS: This is a single center experience of advanced GIST patients where small intestine was found to be the commonest disease site with imatinib producing disease stabilization in more than half of patients. Even though the survival was comparable to published reports, the major limitation was lack of mutation analysis.

Poor Response to Standard Chemotherapy in Early T-precursor (ETP)-ALL: A Subtype of T-ALL Associated with Unfavourable Outcome: A Brief Report.

Early T-precursor (ETP)-ALL, a type of T-ALL, is a new pathobiologic entity with distinct immunophenotype (CD1a(-), CD8(-), CD5(weak/absent) with stem-cell/myeloid markers) and genetic expression, poor response to standard intensive chemotherapy and very high risk of relapse. The genetic mutations typically associated with the pathogenesis of acute myeloid leukemia are seen with increased prevalence in ETP-ALL. No Indian data exists regarding this rare entity. Recently we have seen six cases of ETP-ALL and hereby reporting their clinical characteristics and treatment outcome. All patients were given induction chemotherapy according to standard protocols. Only one out of six patients could achieve remission after induction therapy. Rest five patients died because of their leukemia. This reflects the aggressive biology of this disease and its poor response to standard chemotherapy regimens generally used in T-ALL. The limited experience with ETP-ALL reflects whether rarity of this condition or failure to recognize this is not clear at this time. More studies are required to understand the basic biology of this disease and new therapeutic strategies need to be devised.

Successful treatment of disseminated subcutaneous panniculitis-like T-cell lymphoma with single agent oral cyclosporine as a first line therapy.

Subcutaneous panniculitis-like T-cell lymphoma (SPTL) is a rare cutaneous neoplasm of mature cytotoxic T-cells. Currently there are no standardized therapies for SPTL; however good responses have been seen with chemotherapy regimens generally employed for B-cell lymphomas. Cyclosporine, an immunosuppressant, has shown good responses in relapsed/refractory SPTL; however its use in first line setting is not well established. We, herein, describe a 22-year-old girl with disseminated SPTL who attained complete clinical remission with single agent oral cyclosporine used as a first line therapy.
