Prospective Nonrandomized Comparison Between Open and Robot-Assisted Kidney Transplantation: Analysis of Midterm Functional Outcomes.

Introduction: To compare short- and midterm outcomes of the first 55 patients undergoing robot-assisted kidney transplant (RAKT) with patients undergoing open kidney transplant (OKT) during the same period in a tertiary care hospital. Materials and Methods: Data of all end-stage renal disease patients undergoing renal transplant were prospectively maintained. All graft kidneys were harvested laparoscopically. Both RAKT and OKT were performed using standardized techniques, and all RAKTs were performed by a single experienced robotic surgeon. Chi-square test/Fisher exact test was done for categorical data, and Mann-Whitney U test was done for continuous data. Discrete variables were expressed in absolute numbers and percentages. For all tests, p < 0.05 was considered significant. All results were expressed as mean ± standard deviation or median with range. Results: Between April 2016 and September 2018, 55 patients underwent RAKT. The same was compared with 152 patients who underwent OKT. The two groups were comparable in terms of age, gender, and body mass index. Duration on hemodialysis was significantly higher in the RAKT group, and hemoglobin and donor kidney glomerular filtration rate was significantly better in the RAKT group. Requirement of perioperative analgesia was significantly less in the RAKT group. Rewarm ischemia time was significantly longer in the RAKT group. The fall in serum creatinine was slower in RAKT group till 3 months. The serum creatinine levels were statistically similar in the two cohorts at 3 months (p = 0.082), which was maintained at median 29 months of follow-up (p = 0.067). Tacrolimus levels on postoperative day 2 were found to be significantly higher in RAKT cohort (17.98 ± 14.41) vs OKT cohort (11.38 ± 6.93). Surgical-site infections were rare in the RAKT group. Conclusions: RAKT confers advantage of decreased wound morbidity with similar functional outcomes compared with OKT in midterm. It looks promising; however, long-term follow-up of larger numbers of patients is needed.

Adrenocortical Suppression in Children with Nephrotic Syndrome Treated with Low-Dose Alternate Day Corticosteroids.

Corticosteroids form the mainstay of therapy for all forms of nephrotic syndrome. The long-term use of this medication is associated with serious side effects including adrenocortical suppression. The primary objective of this study was to identify adrenocortical suppression (assessed by single morning serum cortisol levels) in children with nephrotic syndrome on treatment with low-dose alternate day steroids. This cross-sectional study was conducted in the Department of Pediatrics in a tertiary care hospital from January 2014 to January 2015. Seventy children (1-18 years) with nephrotic syndrome (steroid sensitive and resistant) who were in remission and on low-dose alternate day steroids for at least 8 weeks or had received steroids of 2 mg/kg/d for at least 2 weeks in the last 1 year (infrequent relapsers) were enrolled. Relevant history was taken, clinical examination was done and blood samples were drawn for serum cortisol, lipid profile, kidney function tests, fasting blood sugar, glycated hemoglobin (HbA1c), and serum albumin. Forty percent (28/70) children had adrenocortical suppression as assessed by low morning serum cortisol levels. The mean serum cortisol levels were 188 nmol/L and were significantly lower in frequently relapsing individuals (85.9 nmol/L) as compared to other types of nephrotic syndrome (P = 0.05). The prevalence of adrenocortical suppression was higher in steroid-resistant patients (57%) as compared to 28% in frequently relapsing and 11% in steroid-dependent patients. Fifty-seven percent of patients with adrenocortical suppression had short stature while 50% had obesity. All individuals had normal serum HbA1c levels. The cumulative steroid doses and total duration of corticosteroid therapy were significantly higher in patients with adrenocortical suppression. Children with nephrotic syndrome treated with low-dose alternate day steroids have a high prevalence of adrenocortical suppression on screening with single morning cortisol sample. Those with frequently relapsing or steroid-resistant diseases are at a higher risk of suppression.

Enhancement of coral calcification via the interplay of nickel and urease.

Corals are the main reef builders through the formation of calcium carbonate skeletons. In recent decades, coral calcification has however been impacted by many global (climate change) and local stressors (such as destructive fishing practices and changes in water quality). In this particular context, it is crucial to identify and characterize the various factors that promote coral calcification. We thus performed the first investigation of the effect of nickel and urea enrichment on the calcification rates of three coral species. These two factors may indeed interact with calcification through the activity of urease, which catalyzes the hydrolysis of urea to produce inorganic carbon and ammonia that are involved in the calcification process. Experiments were performed with the asymbiotic coral Dendrophyllia arbuscula and, to further assess if urea and/or nickel has an indirect link with calcification through photosynthesis, results were compared with those obtained with two symbiotic corals, Acropora muricata and Pocillopora damicornis, for which we also measured photosynthetic rates. Ambient and enriched nickel (0.12 and 3.50 µg L-1) combined with ambient and enriched urea concentrations (0.26 and 5.52 µmol L-1) were tested during 4 weeks in aquaria. We demonstrate in the study that a nickel enrichment alone or combined with a urea enrichment strongly stimulated urea uptake rates of the three tested species. In addition, this enhancement of urea uptake and hydrolysis significantly increased the long-term calcification rates (i.e. growth) of the three coral species investigated, inducing a 1.49-fold to 1.64-fold increase, respectively for D. arbuscula and P. damicornis. Since calcification was greatly enhanced by nickel in the asymbiotic coral species - i.e. in absence of photosynthesis - we concluded that the effect of increased urease activity on calcification was mainly direct. According to our results, it can be assumed that corals in some fringing reefs, benefiting from seawater enriched in nickel may have advantages and might be able to use urea more effectively as a carbon and nitrogen source. It can also be suggested that urea, for which hotspots are regularly measured in reef waters may alleviate the negative consequences of thermal stress on corals.

The effects of Hurricane Sandy on trauma center admissions.

BACKGROUND: Hurricane Sandy was a particularly unusual storm with regard to both size and location of landfall. The storm landed in New Jersey, which is unusual for a tropical storm of such scale, and created hazardous conditions which caused injury to residents during the storm and in the months following. This study aims to describe differences in trauma center admissions and patterns of injury during this time period when compared to a period with no such storm. METHODS: Data were collected for this study from patients who were admitted to the trauma center at Morristown Medical Center during Hurricane Sandy or the ensuing cleanup efforts (patients admitted between 29 October 2012 and 27 December 2012) as well as a control group consisting of all patients admitted to the trauma center between 29 October 2013 and 27 December 2013. Patient information was collected to compare the admissions of the trauma center during the period of the storm and cleanup to the control period. RESULTS: A total of 419 cases were identified in the storm and cleanup period. 427 were identified for the control. Striking injuries were more common in the storm and cleanup group by 266.7% (p = 0.0107); cuts were more common by 650.8% (p = 0.0044). Medical records indicate that many of these injuries were caused by Hurricane Sandy. Self-inflicted injuries were more common by 301.3% (p = 0.0294). There were no significant differences in the total number of patients, mortality, or injury severity score between the two cohorts. CONCLUSION: The data we have collected show that the conditions caused by Hurricane Sandy and the following cleanup had a significant effect on injury patterns, with more patients having been injured by being struck by falling or thrown objects, cut while using tools, or causing self-inflicted injuries. These changes, particularly during the cleanup period, are indicative of environmental changes following the storm which increase these risks of injury.

Collapsing glomerulopathy associated with hepatitis B infection: A case report.

Collapsing glomerulopathy has been classified as a variant of focal segmental glomerulosclerosis. It is associated with infections, inflammations, and certain medications. While its association with human immunodeficiency virus has been well established its occurrence with hepatitis B has not been reported. We present here a case of collapsing glomerulopathy in a child with hepatitis B infection.

Cedecea lapagei in a patient with malignancy: Report of a rare case.

Cedecea lapagei is a member of the family Enterobacteriaceae and is an uncommon pathogen. There are very few reports of isolation of this organism from biological samples; mostly it is found to be a pathogen in elderly or otherwise medically compromised. We present a rare case of a patient with underlying malignancy of buccal mucosa, who developed an oral ulcer superinfected with C. lapagei. According to the available literature, this is the first case of C. lapagei from India detected in a cancer patient.

Rhabdomyosarcoma infiltrating bone marrow.

We present a case of 26-year-old male, previously diagnosed as rhabdomyosarcoma (RMS) of perineal region. The peripheral smear showed a leukoerythroblastic picture with an occasional atypical cell. The bone marrow aspirate and biopsy showed monotonous sheets of malignant cells. On immunohistochemistry the tumor cells were strongly positive for desmin and negative for CD34 and CD117. This case illustrates the morphology and IHC findings in a case of RMS. Immunostains like CD34 and CD117 should be included to rule out a possibility of acute leukemia.

Information and rehabilitation needs of Indian breast cancer patients: Report of a cross-sectional study.

Background: Breast cancer causes significant disruption to the quality of life (QOL) of its patients, which is compounded further by lack of information and adequate facilities for rehabilitation. Materials and Methods: This descriptive cross-sectional study was conducted in women who had completed their Primary treatment of breast cancer. The QOL was assessed by Functional assessment of cancer therapy-breast (FACT-B) version 4, and information and rehabilitation needs were enquired about in a semi-structured interview. Results: A total of 154 patients were enrolled and divided into three groups according to the time elapsed after initial treatment; Group I: 1-2 years, Group II: 2-5 years, Group III: >5 years The FACT-B mean scores were; Group I (n = 64): 79.06 ± 14.60; Group II (n = 48): 85.75 ± 20.15; and Group III (n = 42): 89.83 ± 12.80. Patients in Group I scored lowest on physical well-being subscale, Group II on breast specific subscale and Group III on Social well-being subscale. Pain, lack of energy, inability to meet the needs of the family, fear that the condition will get worse and loss of body image were significant factors contributing to poor QOL. Analysis of interviewshowed many unmet information needs. Main rehabilitation needs were effective treatment of physical symptoms and counselling about body image issues and sexual dysfunctions. Easy availability of clinical and social support services were major felt needs in the long-term follow-up. Conclusions: Targeted Interventions are needed to address issues relating to QOL and rehabilitation needs of breast cancer patients.

Non-pigmented strain of serratia marcescens: an unusual pathogen causing pulmonary infection in a patient with malignancy.

Serratia marcescens is a member of the family Enterobacteriaceae. It has emerged in recent years as an opportunistic pathogen of nosocomial infections. Some biotypes of Serratia marcescens produce the non-diffusible red pigment prodigiosin. Though both pigmented and non-pigmented biotypes may be pathogenic for humans, the non-pigmented biotypes are more virulent due to cytotoxin production and presence of plasmids mediating antibiotic resistance. However in India only one study done 31 years back has reported on infections caused by non-pigmented strains of Serratia marcescens. We present a case of a patient with squamous cell carcinoma of the left retromolar trigone, soft palate and buccal mucosa, who developed pulmonary infection with non-pigmented strain of Serratia marcescens. According to the available literature, this is the second report on infection with non-pigmented strain of Serratia marcescens from India. It is imperative to accurately detect the non-pigmented biotypes due to their tendency to cause serious and difficult to treat infections.

Clinical efficacy of various root canal obturating methods in primary teeth: a comparative study.

AIM: The purpose of this in vivo study was to evaluate and compare the efficacy of different obturating methods used in primary teeth, when obturated using a combination of zinc oxide and iodoform paste (Endoflas F.S.). MATERIALS AND METHODS: A group of 29 patients aged 3-9 years and a total of 64 teeth were selected. These 64 teeth (32 anterior teeth=32 canals, and 32 posterior teeth=80 canals) were randomly divided into 4 groups. Teeth were obturated with Lentulo spiral, pressure syringe, bi-directional spiral and Pastinject. Post-operative evaluation was done for: quality of canal obturation, (underfilled, optimally filled, overfilled) and presence of voids. RESULTS: Pastinject exhibited the highest number of optimally filled canals, while the highest number of underfilled canals were observed with bi-directional spiral, and the highest number of overfilled canals were observed with pressure syringe. A minimum number of voids was present in canals filled with the Pastinject technique and pressure syringe. CONCLUSION: These results suggest that Pastinject was the most effective technique for obturation of primary teeth.

Effect of a natural mutation in the 5' untranslated region on the translational control of p53 mRNA.

Tumor-suppressor protein p53, the 'guardian of the genome', is critical in maintaining cellular homeostasis and genomic stability. Earlier, we have reported the discovery of internal ribosome entry sites (IRESs) within the p53 mRNA that regulate the translation of the full length and its N-terminal-truncated isoform, ΔN-p53. Polypyrimidine tract-binding protein (PTB) is an IRES trans-acting factor that positively regulates the IRES activities of both p53 isoforms by relocating from nucleus to the cytoplasm during stress conditions. Here we have demonstrated the putative contact points of PTB on the p53 IRES RNA. Studies on mutations that occur naturally in the 5' untranslated region (5' UTR) in p53 mRNA were lacking. We have investigated a naturally occurring C-to-T single-nucleotide polymorphism (SNP) first reported in human melanoma tumors. This SNP is at position 119 in the 5' UTR of p53 mRNA and we demonstrate that it has consequences on the translational control of p53. Introduction of this SNP has led to decrease in cap-independent translation from p53 5' UTR in bicistronic reporter assay. Further, the effects of this SNP on cap-independent translation have been studied in the context of p53 cDNA as well. Interestingly, the 5' UTR with this SNP has shown reduced binding to PTB that can be corroborated to its weaker IRES activity. Previously, it has been shown that G2-M checkpoint, DNA-damaging stress and oncogenic insult favor IRES-mediated translation. Under similar conditions, we demonstrate that this SNP interferes with the enhancement of the IRES activity of the 5' UTR. Taken together, the results demonstrate for the first time that SNP in the 5' UTR of the p53 mRNA might have a role in translational control of this critical tumor-suppressor gene.

Relationship of leukocyte CR1 transcript and protein with the pathophysiology and prognosis of systemic lupus erythematosus: a follow-up study.

Complement Receptor 1 (CR1) is a key complement regulatory protein (CRP) involved in the clearance of immune complexes. Earlier, we reported a marked decline of leukocyte CR1 (L-CR1) transcript and protein in patients with active systemic lupus erythematosus (SLE) and suggested L-CR1 transcript as a putative non-invasive disease marker for SLE. This follow-up study involving 18 patients with active SLE was conducted for further confirmation of the relationship between L-CR1 and SLE. Blood samples from the patients were collected on day 1 of the diagnosis (0 month) and at different time intervals (3 and 6 months) for analysis of L-CR1 transcript and L-CR1 protein by semi-quantitative reverse-transcriptase-polymerase chain reaction (RT-PCR) and western blotting respectively. Within 6 months, 15 patients entered remission. On day 1, the mean values of L-CR1 transcript (8.42 ± 3.53) and L-CR1 protein (4683 ± 1094) in the SLE patients were 6 times and 12 times lower than the normal controls (n = 103). At the end of month 6, these values increased by 4.5 and 6.5 times respectively for CR1 transcript (37.86 ± 8.52) and protein (30,265 ± 8614). Simultaneously, the SLE Disease Activity Index (SLEDAI) scores decreased by 4.8 times (4.47 ± 3.32) as compared with the scores obtained on day 1 (21.45 ± 5.67). Moreover, CR1 values correlated negatively with the SLEDAI scores. Levels of L-CR1 protein and transcript remained low in the three patients who did not enter remission. All of the above results suggested that an increase in the levels of L-CR1 related to good prognosis. Since the levels of L-CR1 protein is influenced by variables like proteolytic cleavage and secretion from leukocytes, the values of L-CR1 transcript on day 1 and subsequent follow-up points may bring a better insight into the state of the disease activity. An extended follow-up study is needed to confirm the significance of L-CR1 as a prognostic marker for SLE.

Post-operative hilotherapy in SMAS-based facelift surgery: a prospective, randomised, controlled trial.

BACKGROUND: Ecchymosis, oedema, haematoma and pain after SMAS-based facelift surgery are all the direct result of the physical trauma of surgery and subsequent inflammatory response. Hilotherapy is a novel form of cryotherapy that purports to minimise these events through single-use face masks circulating cooled, sterile water. This study was performed to assess the validity of Hilotherapy in this population of patients. METHODS: Over 14 weeks fifty consecutive patients were randomised to post-operative facial cooling with Hilotherapy or management with standard dressings alone, while fifteen subsequent, consecutive patients were randomised to cooling of one side of the face but not the other. Assessment of ecchymosis, oedema, haematoma and pain was performed independently by clinical staff and patients. The second analysis was undertaken to better delineate pain relief using each individual patient as their own control. RESULTS: The Hilotherapy mask produced a statistically significant difference in facial skin temperature (p = 0.01). In the second limb of the study patients reported a statistically significant increase in facial swelling 6-8 days post surgery in the half of the face that was treated with the mask (p = 0.05) but there was no significant difference in ecchymosis, haematoma and pain between comparison groups (p > 0.10) in either limb of the study. Subjectively the majority of patients found the cooling masks to be comforting. CONCLUSION: In this randomised, controlled trial the Hilotherapy mask produced significant facial skin cooling after SMAS-based facelift surgery at the expense of a statistically significant increase in patient reported post-operative swelling. No objective benefits were derived in terms of reducing ecchymosis, haematoma or pain.

Breast enhancement using Macrolane™: a report of complications in three patients and a review of this new product.

Macrolane™, an injectable compound composed of hyaluronic acid, has recently been marketed for breast enhancement. Three patients who presented to the authors with complications soon after treatment elsewhere are reported. One had severe infection and two had grade 3 capsular contracture. All three patients underwent a surgical procedure to treat their complication. The use of Macrolane™ for breast enhancement is reviewed together with previously published data.

p53 and little brother p53/47: linking IRES activities with protein functions.

The tumor suppressor p53 represents a paradigm for gene regulation. Its rapid induction in response to DNA damage conditions has been attributed to both increased half-life of p53 protein and also increased translation of p53 mRNA. Recent advances in our understanding of the post-transcriptional regulation of p53 include the discovery of internal ribosome entry sites (IRESs) within the p53 mRNA. These IRES elements regulate the translation of the full length as well as the N-terminally truncated isoform, p53/47. The p53/47 isoform is generated by alternative initiation at an internal AUG codon present within the p53 ORF. The aim of this review is to summarize the role of translational control mechanisms in regulating p53 functions. We discuss here in detail how diverse cellular stress pathways trigger alterations in the cap-dependent and cap-independent translation of p53 mRNA and how changes in the relative expression levels of p53 isoforms result in more differentiated p53 activity.
