Oxalate nephropathy and chronic turmeric supplementation: a case report / Nefropatia por oxalato e suplementação crônica de cúrcuma: relato de caso

ABSTRACT We present a case of a 69-year-old man who presented for routine check-up and was incidentally found to have kidney failure with an initially unrevealing history and bland urinary sediment. He was diagnosed with oxalate nephropathy in the setting of chronic turmeric supplementation and chronic antibiotic therapy with associated diarrhea. Our case provides several key insights into oxalate nephropathy. First, the diagnosis requires a high index of clinical suspicion. It is uncommonly suspected clinically unless there is an obvious clue in the history such as Roux-en-Y gastric bypass or ethylene glycol poisoning. Diagnosis can be confirmed by histopathologic findings and corroborated by serum levels of oxalate and 24-hour urinary excretion. Second, the diagnosis can often be missed by the pathologist because of the characteristics of the crystals unless the renal pathologist has made it a rule to examine routinely all H&E sections under polarized light. This must be done on H&E, as the other stains dissolve the crystals. Third, one oxalate crystal in a routine needle biopsy is considered pathologic and potentially contributing to the AKI or to the CKD in an important way. Fourth, secondary oxalosis can be largely mitigated or prevented in many cases, especially iatrogenic cases. This can come through the surgeon or the gastroenterologist providing proper instructions to patients on an oxalate-restricted diet or other specific dietary measures. Lastly, this case highlights the success that results from cooperation and communication between the pathologist and the treating physician.

RESUMO Relatamos o caso de um homem de 69 anos que se apresentou para exame de rotina e descobriu-se incidentalmente que ele tinha insuficiência renal, com histórico inicialmente não revelador e sedimento urinário brando. Ele foi diagnosticado com nefropatia por oxalato no contexto de suplementação crônica de cúrcuma e antibioticoterapia crônica com diarreia associada. Nosso caso fornece diversas sugestões importantes sobre nefropatia por oxalato. Primeiro, o diagnóstico requer elevado índice de suspeita clínica. A suspeita clínica é incomum, a menos que haja evidência óbvia no histórico, como bypass gástrico em Y de Roux ou envenenamento por etilenoglicol. O diagnóstico pode ser confirmado por achados histopatológicos e corroborado por níveis séricos de oxalato e excreção urinária de 24 horas. Segundo, o diagnóstico pode passar despercebido pelo patologista devido às características dos cristais, a menos que o patologista renal estabeleça como regra examinar rotineiramente todas as seções coradas com H&E sob luz polarizada. Isso deve ser feito com H&E, pois, outras colorações dissolvem os cristais. Em terceiro lugar, um cristal de oxalato em biópsia por agulha de rotina é considerado patológico, contribuindo potencialmente para LRA ou para DRC de maneira significativa. Em quarto lugar, a oxalose secundária pode ser amplamente mitigada ou prevenida em muitos casos, especialmente casos iatrogênicos. Isso pode ser feito pelo cirurgião ou pelo gastroenterologista, fornecendo instruções adequadas aos pacientes sobre uma dieta restrita em oxalato ou outras medidas dietéticas específicas. Por fim, esse caso destaca o sucesso que resulta da cooperação e comunicação entre o patologista e o médico assistente.

Perineural low dexamethasone dose as adjuvant in supraclavicular brachial plexus block for arteriovenous fistula creation in end stage renal disease: a randomized controlled trial

Abstract Background and aims: Dexamethasone as adjunct to local anesthetic solution improves the quality of brachial plexus block (BPB). However, evidence for its efficacy at low doses (< 4 mg) is lacking. This study was designed to evaluate the duration of analgesia attained with low dose dexamethasone as adjuvant to local anesthetic for creation of arteriovenous fistula (AVF) under BPB. Methods: Sixty-six patients scheduled for AVF creation were randomly allocated to receive either saline (control) or 2 mg dexamethasone, together with 0.5% ropivacaine and 0.2% lignocaine. The primary outcome was duration of analgesia, defined as time from performing the block to the first analgesic request. The secondary outcomes were time from injection to complete sensory block, time from injection to complete motor block, duration of motor block, postoperative analgesic consumption, and fistula patency at three months. Results: All the blocks were effective. In the group that received dexamethasone, the time to first analgesic request was significantly delayed (432 ± 43.8 minutes vs. 386.4 ± 40.2 minutes; p < 0.01). The onset of sensory and motor blockade occurred faster in dexamethasone group and overall analgesic consumption was also reduced. However, dexamethasone addition did not prolong the duration of motor block. There was no statistically significant difference in the patency of fistulas between the two groups at three months. (p = 0.34). Conclusion: Addition of low-dose perineural dexamethasone to local anesthetic solution significantly prolonged the duration of analgesia. Further trials are warranted to compare the adverse effects between dexamethasone doses of 4 mg and lower.

Frailty and chronic kidney disease: associations and implications / Fragilidade e doença renal crônica: associações e implicações

ABSTRACT Introduction: Frailty and its association with chronic kidney disease (CKD) has been established previously. The present study examined this association further by studying the distribution of frailty among groups defined by different stages of the disease. It also identified associated health deficits and explored their association with estimated glomerular filtration rate (eGFR) and urine albumin creatinine ratio (UACR). Methods: A cross-sectional survey was conducted on 90 non-dialysis dependent CKD Stage 1-4 patients, recruited in three stratified groups of 30 participants each based on the stage of disease. Frailty was assessed using Fried's frailty criteria and associated health deficits were recorded using a pre-determined list. Depression was screened using a 4-point depression scale. Results: 21.1% of the participants were frail and 43.3% were pre-frail. The proportion of frailty in CKD groups A (Stages 1 and 2), B (Stage 3a), and C (Stages 3b and 4) was 10%, 13.3%, and 40%, respectively. The association of health deficits including co-morbidities, physical parameters, mental status, daily activities, etc. with UACR, eGFR, and CKD stages was not statistically significant. Nearly one in two frail participants was depressed compared with 14% among non-frail participants. Conclusion: The skewed distribution of 21% frail subjects identified in our study indicates an association between frailty and advancing kidney disease. Frail individuals had a lower eGFR, higher UACR, were more likely to be depressed, and had higher count of health deficits and poorer performance on Barthel Index of Activities of Daily Living and WHOQOL. Early identification of depression would improve care in these patients.

RESUMO Introdução: Fragilidade e sua associação com DRC foram estabelecidas anteriormente. O presente estudo aprofundou esta associação, estudando distribuição da fragilidade entre grupos definidos por diferentes estágios da doença. Também identificou déficits de saúde associados e explorou sua associação com taxa de filtração glomerular estimada (TFGe) e relação albumina/creatinina urinária (RAC). Métodos: Realizou-se uma pesquisa transversal em 90 pacientes com DRC Estágios 1-4 não dependentes de diálise, recrutados em três grupos estratificados de 30 participantes cada, conforme estágio da doença. Avaliou-se fragilidade usando os critérios de fragilidade de Fried e registraram-se os déficits de saúde associados usando uma lista pré-determinada. A depressão foi verificada utilizando a escala de depressão de 4 pontos. Resultados: 21,1% dos participantes eram frágeis e 43,3% eram pré-frágeis. A proporção de fragilidade nos grupos de DRC A (Estágios 1 e 2), B (Estágio 3a), e C (Estágios 3b e 4) foi de 10%, 13,3%, 40% respectivamente. A associação de déficits de saúde, incluindo comorbidades, parâmetros físicos, estado mental, atividades diárias etc. com RAC, TFGe e estágios da DRC não foi estatisticamente significativa. Cerca de um em cada dois participantes frágeis estava depressivo comparados com 14% entre não frágeis. Conclusão: A distribuição enviesada de 21% dos indivíduos frágeis identificados em nosso estudo indica associação entre fragilidade e doença renal progressiva. Indivíduos frágeis apresentaram menor TFGe, maior RAC, eram mais propensos a depressão, tinham maior índice de déficits de saúde e desempenho inferior no Índice de Atividades da Vida Diária de Barthel e WHOQOL. A identificação precoce da depressão melhoraria o atendimento desses pacientes.

Unusual Arteriovenous Malformation in Total Hip Arthroplasty: Case Report of a Complicated Perioperative Course / Malformação arteriovenosa incomum em artroplastia total do quadril: relato de caso de um perioperatório de curso complicado

Abstract It is not common to encounter arteriovenous malformations (AVMs) during total hip arthroplasty (THA). We report the present case to draw attention to the possibility of an AVM during the direct anterior approach (DAA) for THA, which, if not borne in mind, may lead to the myriad of complications related to excessive bleeding. An 81-year-old female presented to the emergency department with a left femoral neck fracture. She elected to undergo a THA via the DAA. Abnormal appearing blood vessels were present near the ascending circumflex branches, which provided difficulty in achieving hemostasis. Excessive blood loss was noted, and the patient received one unit of packed red blood cells during the operation. Hemoglobin and hematocrit dropped in the days following surgery, requiring several additional transfusions of blood products. When the patient complained of progressive left leg swelling on postoperative day 3, a computed tomography revealed large hematomas within the left adductors and the left iliopsoas muscle. Active extravasation was identified arising from a branch of the left profunda femoral artery, as well as an arteriovenous fistula (AVF) in this area. Bleeding was controlled by selective endovascular coil embolization. As of current knowledge, this is the first reported intraoperative discovery of congenital arteriovenous malformation (AVM) with subsequent development of postoperative arteriovenous fistula and associated symptomatic hematomas in the setting of THA using the DAA. Early recognition and intervention of vascular malformations is essential in preventing potential limb- or life-threatening surgical complication.

Resumo Não é comum encontrar malformações arteriovenosas (MAV) durante a artroplastia total do quadril (ATQ). Relatamos o presente caso para chamar a atenção para a possibilidade de uma MAV durante a abordagem anterior direta (AAD) para ATQ, que se não for considerada, pode levar a uma miríade de complicações relacionadas ao sangramento excessivo. Uma mulher de 81 anos foi apresentada ao pronto-socorro com fratura no pescoço do fêmur esquerdo. Ela optou por se submeter a uma artroplastia total do quadril (ATQ) através da AAD. Vasos sanguíneos aparentemente anormais estavam presentes perto dos ramos circunflexos ascendentes, proporcionando dificuldade em alcançar hemostasia. A perda excessiva de sangue foi notada e a paciente recebeu uma unidade de glóbulos vermelhos embalados durante a operação. Hemoglobina e hematócrito caíram nos dias seguintes à cirurgia, exigindo várias transfusões adicionais de produtos sanguíneos. Quando a paciente reclamou de inchaço progressivo na perna esquerda no terceiro dia pós-operatório, a tomografia computadorizada revelou hematomas grandes dentro dos adutores esquerdos e do músculo iliopsoas esquerdo. A extravasão ativa foi identificada a partir de um ramo da artéria femoral esquerda, bem como de uma fístula arteriovenosa (FAV) nesta área. O sangramento foi controlado por embolização seletiva da bobina endovascular. A partir do conhecimento atual, esta é a primeira descoberta intraoperatória relatada de MAC congênita com desenvolvimento subsequente de FAV pós-operatória e hematomas sintomáticos associados no cenário de ATQ utilizando a AAD. O reconhecimento precoce e a intervenção de malformações vasculares são essenciais para prevenir possíveis complicações cirúrgicas de membros ou de risco de vida.

Clinicodermoscopic and immunopathological profile of non-infectious non-eczematous inflammatory tattoo reactions: A retrospective study from a tertiary care centre of East India

Introduction: Tattoo-associated complications are on the rise due to the popularity of decorative tattoos in recent years. The exact pathogeneses of various tattoo reaction patterns are still unclear, and their dermoscopic details are sparsely reported. Aim: We aimed to retrospectively study the clinical, dermoscopic and immunopathological details of patients with non-infectious, non-eczematous inflammatory tattoo reaction patterns in a tertiary care centre of East India. Method: The clinical, dermoscopic and pathological details of all the patients who had non-infectious, non-eczematous inflammatory tattoo reactions were collected. In all the cases, immunohistochemistry was done for CD1a, CD3, CD4, CD8, FoxP3, CD20 and CD56. Results: A total of five patients of skin phototypes IV and V and six tattoo reactions were analysed. Five lesions had reactions at the site of a black tattoo, and one at the site of red tattoo. Clinically, the patients presented with erythematous or blue-grey flat-topped to verrucous papules and plaques. Dermoscopic features were dominated by a central white to pink-white structureless area, a peripheral grey-white to bluish-white structureless area, white scales, comedo-like opening with keratotic plugging, milia-like cysts and shiny white structures. Pathologically, except for one lesion that only showed a lichenoid reaction pattern in the red tattoo, all had a combination of reaction patterns. Immunohistochemistry showed increased epidermal and dermal Langerhans cells, predominantly CD8 positive T cells in the epidermis and dermis, sparse dermal B cells and CD4 positive T cells, reduced T regulatory cells and a complete absence of CD56 positive NK cells. Limitations: Small sample size was the limitation of the study. Conclusion: The clinical morphology and dermoscopy may not differentiate between various types of non-infectious non-eczematous inflammatory tattoo reactions. The immunological profile supports a delayed hypersensitivity reaction due to contact sensitisation to tattoo pigment, and CD8 positive T cells play a central role in executing various pathological reaction patterns, both in the epidermis and dermis

Etiology and Outcome of Community-Acquired Acute Kidney Injury in Pediatric Inpatients

Objective: To estimate the etiology, outcome, and risk factors for mortality in children with community-acquired acute kidney injury (CA-AKI). Methods: Between October, 2020 and December, 2021, consecutive hospitalized children aged 2 mo-12 years with a minimum 24 hours of stay, and at least one serum creatinine level measured at or within 24 hours of hospitalization were prospectively enrolled. CA-AKI was labelled in children with an elevated serum creatinine level at admission and subsequent fall during hospitalization. Results: Of 2780 children, 215 were diagnosed as CA-AKI (7.7%, 95% CI 6.7-8.6). Diarrhea with dehydration (39%) and sepsis (28%) were the most common causes of CA-AKI. 24 children (11%) died during hospitalization. Requirement of inotropes was an independent predictor of mortality. Out of 191 children discharged, 168 (88%) had complete renal recovery. At 3 months, out of 22 children without complete renal recovery, 10 progressed to chronic kidney disease (CKD), with 3 becoming dialysis dependent. Conclusions: CA-AKI is common in hospitalized children, and is associated with increased risk of progression to CKD, especially in those with incomplete renal recovery.

Abdominoscrotal hydrocele with ipsilateral hydroureteronephrosis in an adult: A case report

Abdominoscrotal hydrocele (ASH) is very rare in adults and difficult to suspect on clinical examination. ASH is a very unusual presentation of scrotal hydrocele with extension intra-abdominally through the inguinal canal either communicating to the peritoneal cavity or non-communicating. An ASH is a congenital pathology involving a scrotal hydrocele expanding through the inguinal canal and reaching the abdominal cavity. Here, we present the case of a 25-year-old man admitted with a complaint of pain and lump in the left lower abdomen for 2 months and swelling in the left groin for 2 years. Ultrasound and computed tomography suggest left ASH with left-sided hydroureteronephrosis. A left DJ stent was placed and on exploration, a large cystic mass was seen intraperitoneally extending into the scrotum through the inguinal canal. Excision of the abdominal part and partial excision of the scrotal part were done with eversion of the remaining tunica vaginalis sac. Although ASH is a rare entity, it should always be kept on the list of differential diagnoses during the complaint of large abdominal mass in adults.

Transcatheter Mitral Valve Implantation: Implications of Interventional Technique and 3D Echocardiography for Complex Valve?in?Valve Paravalvular Leak

Transcatheter mitral valve replacement (TMVR) has emerged as a feasible alternative to surgical reoperation in failed bioprostheses and rings. Residual mitral regurgitation following TMVR can present as a valve?in?valve paravalvular leak (PVL) and is associated with increased morbidity and mortality. Current therapies for valve?in?valve PVL are limited. We present a case of a symptomatic patient with severe valve?in?valve PVL after TMVR for a previous surgical bioprosthesis leak, who then underwent a second TMVR as a valve?in?valve?in?valve implantation with a 29 mm Edwards? SAPIEN 3 valve via transseptal approach using three?dimensional (3D) echocardiography. This unique case highlights the complexity of this clinical entity and recognizes 3D transesophageal echocardiography as a valuable tool to guide valve?in?valve PVL closures.echocardiography

Outcomes of children with idiopathic steroid resistant nephrotic syndrome: a single centre observational study / Desfechos de crianças com síndrome nefrótica idiopática córtico-resistente: um estudo observacional de centro único

ABSTRACT Introduction: Idiopathic steroid resistant nephrotic syndrome (SRNS) has variable outcomes in children. The primary objective of the present study was to assess the cumulative remission rate and the secondary objectives were to assess factors affecting the remission status, kidney function survival, and adverse effects of medications. Methods: One hundred fourteen patients with SRNS were included. Calcineurin inhibitor-based treatment protocol along with prednisolone and angiotensin-converting enzyme inhibitor were used, and patients were followed over 5 years. Results: Median age was 4.5 years; 53.5% of cases were between 1 to 5 years of age. Sixty-two patients (54.4%) were at initial stage and 52 (45.6%) were at a late SRNS stage. Median eGFRcr was 83.5 mL/min/1.73m2 at presentation. Of the 110 patients, 63 (57.3%) achieved remission [complete remission 30 (27.3%), partial remission 33 (30%)], and 47 (42.7%) had no remission. Kidney function survival was 87.3% and 14 cases (12.7%) had progression to CKD (G3-8, G4-3, G5-1, and G5D-2). Median duration of follow up was 36 months (IQR 24, 60). Age of onset, cyclosporine/tacrolimus, eGFRcr, and histopathology (MCD/FSGS) did not affect remission. Similarly, remission status in addition to age of onset, drug protocol, and histopathology did not significantly affect kidney function during a period of 5 years. Hypertension, cushingoid facies, short stature, cataract, and obesity were observed in 37.7, 29.8, 25.5, 17.5, and 0.7% of cases, respectively. Conclusion: About half of the cases achieved remission. Age of onset of disease, cyclosporine/tacrolimus use, and histopathological lesion neither affected remission status nor short-term kidney function survival in SRNS.

RESUMO Introdução: A síndrome nefrótica idiopática córtico-resistente (SNICR) apresenta desfechos variáveis em crianças. O objetivo principal deste estudo foi avaliar a taxa de remissão cumulativa. Os objetivos secundários foram avaliar fatores que afetam status de remissão, sobrevida da função renal e efeitos adversos de medicamentos. Métodos: Foram incluídos 114 pacientes com SNCR. Utilizou-se protocolo de tratamento baseado em inibidores de calcineurina juntamente com prednisolona e inibidor da enzima conversora de angiotensina. Os pacientes foram acompanhados durante 5 anos. Resultados: A idade mediana foi 4,5 anos; 53,5% dos casos tinham entre 1 e 5 anos. 62 pacientes (54,4%) estavam em estágio inicial; 52 (45,6%) em estágio tardio da SNCR. A TFGecr mediana foi 83,5 mL/min/1,73 m2 na apresentação. Dos 110 pacientes, 63 (57,3%) alcançaram remissão [remissão completa 30 (27,3%), remissão parcial 33 (30%)], e 47 (42,7%) não apresentaram remissão. A sobrevida da função renal foi 87,3%; 14 casos (12,7%) progrediram para DRC (G3-8, G4-3, G5-1, G5D-2). A duração mediana do acompanhamento foi 36 meses (IIQ 24, 60). Idade no início, ciclosporina/tacrolimus, TFGecr e histopatologia (DLM/GESF) não afetaram a remissão. Igualmente, status de remissão, além da idade no início, protocolo de medicamentos e histopatologia não afetaram significativamente a função renal por 5 anos. Observou-se hipertensão, fácies cushingoide, baixa estatura, catarata e obesidade em 37,7; 29,8; 25,5; 17,5; e 0,7% dos casos, respectivamente. Conclusão: Aproximadamente metade dos casos alcançou remissão. Idade no início, uso de ciclosporina/tacrolimus e lesão histopatológica não afetaram o status de remissão nem a sobrevida da função renal a curto prazo na SNICR.

Double bubble pneumo-descemetopexy for the management of Descemet membrane detachment: An innovative technique

A 62-year-old woman was referred with poor vision following manual small incision cataract surgery. On presentation, the uncorrected distance visual acuity in the involved eye was 3/60, whereas slit-lamp examination revealed a central corneal edema with the peripheral cornea relatively clear. Direct focal examination with a narrow slit upper border and lower margin of detached rolled up Descemet’s membrane (DM) could be visualized. We performed a novel surgical approach, “double-bubble pneumo-descemetopexy.” The surgical procedure included unrolling of DM with “small air bubble” and descemetopexy with “big bubble.” No postoperative complications were observed, and best corrected distance visual acuity improved to 6/9 at 6 weeks. The patient had a clear cornea and maintained BCVA 6/9 during 18 months at follow-up. Double-bubble pneumo-descemetopexy, a more controlled technique, provides a satisfactory anatomical and visual outcome in DMD without the need for endothelial keratoplasty (Descemet’s stripping endothelial keratoplasty or DMEK) or penetrating keratoplasty.

Risk factors for clinically significant diffuse parenchymal lung abnormalities persisting after severe COVID-19 pneumonia

Background & objectives: The risk factors for clinically significant diffuse parenchymal lung abnormalities (CS-DPLA) persisting after severe coronavirus disease 2019 (COVID-19) pneumonia remain unclear. The present study was conducted to assess whether COVID-19 severity and other parameters are associated with CS-DPLA. Methods: The study participants included patients who recovered after acute severe COVID-19 and presented with CS-DPLA at two or six month follow up and control group (without CS-DPLA). Adults volunteers without any acute illness, chronic respiratory illness and without a history of severe COVID-19 were included as healthy controls for the biomarker study. The CS-DPLA was identified as a multidimensional entity involving clinical, radiological and physiological pulmonary abnormalities. The primary exposure was the neutrophil-lymphocyte ratio (NLR). Recorded confounders included age, sex, peak lactate dehydrogenase (LDH), advanced respiratory support (ARS), length of hospital stay (LOS) and others; associations were analyzed using logistic regression. The baseline serum levels of surfactant protein D, cancer antigen 15-3 and transforming growth factor-? (TGF-?) were also compared among cases, controls and healthy volunteers. Results: We identified 91/160 (56.9%) and 42/144 (29.2%) participants with CS-DPLA at two and six months, respectively. Univariate analyses revealed associations of NLR, peak LDH, ARS and LOS with CS-DPLA at two months and of NLR and LOS at six months. The NLR was not independently associated with CS-DPLA at either visit. Only LOS independently predicted CS-DPLA at two months [adjusted odds ratios (aOR) (95% confidence interval [CI]), 1.16 (1.07-1.25); P<0.001] and six months [aOR (95% CI) and 1.07 (1.01-1.12); P=0.01]. Participants with CS-DPLA at six months had higher baseline serum TGF-? levels than healthy volunteers. Interpretation and conclusions: Longer hospital stay was observed to be the only independent predictor of CS-DPLA six months after severe COVID-19. Serum TGF-? should be evaluated further as a biomarker.

Study of Incidence of Ponticulus Posterior In Dry Human Atlas Vertebra and Its Clinical Significance

Background: Atlas is the first cervical vertebra. The vertebral artery lies in the groove on posterior arch of the atlas. The vertebral artery groove may sometimes get converted into a foramen. This is commonly known as ponticulus posterior (ponticulus posticus) or arcuate foramen of the atlas. These foramina may be complete or incomplete. This can lead to compression of the vertebral artery and produce symptoms like headache, syncope, altered consciousness etc. It can also complicate manipulations of the cervical spine by reducing the blood flow during extreme rotations of head and neck. It is also associated with vertebrobasilar artery stroke So, neurosurgeons or orthopaedic surgeons who operate in this area should have a detailed knowledge of variations of groove for the vertebral artery. Materials and Methods: The present study was conducted on 50 dried and fully ossified adult human atlas of unknown age and sex collected from the department of Anatomy, Government Medical college, Nagpur. Each atlas vertebra was carefully observed for the presence or absence of complete or incomplete ponticuli on superior surface of posterior arch of atlas. Results: Out of the 50 vertebra studied 7(14%) showed the presence of Ponticuli. Ponticuli were incomplete in all 7 atlas vertebras. Complete ring was not observed in any of the atlas vertebra .Out of the 7 ponticuli 6(12%) were found to be unilateral and in only 1 (2%) case it was found to be bilateral. Out of the 6 ponticuli 4(8%) were noticed on the Left side and 2(4%) were present on the right side. Conclusion: Presence of incomplete ponticulus posterior might cause cervical pain and even cerebrovascular disorders due to pressure on third part of vertebral artery present in the vertebral artery groove. This anatomical knowledge is important for neurosurgeons, orthopaedic surgeons, radiologists and clinicians while dealing with this region.

Survival analysis and predictors of long-term outcomes following radical nephrectomy with inferior vena cava (IVC) thrombectomy in renal cell carcinoma

Background: Renal cell carcinoma (RCC) presents with inferior vena cava (IVC) thrombus in 10%�% cases and surgical management forms the mainstay of the treatment. The objective of this study is to assess the outcomes of the patients undergoing radical nephrectomy with IVC thrombectomy. Methods: A retrospective analysis of patients undergoing open radical nephrectomy with IVC thrombectomy between 2006 till 2018 was done. Results: A total of 56 patients were included. The mean (眘tandard deviation) age was 57.1 (�.2) years. The number of patients with levels I, II, III, and IV thrombus were 4, 29,10, and 13, respectively. The mean blood loss was 1851.8 mL, and the mean operative time was 303.3 minutes. Overall, the complication rate was 51.7%, while the perioperative mortality rate was 8.9%. The mean duration of hospital stay was 10.6 � 6.4 days. The majority of the patients had clear cell carcinoma (87.5%). There was a significant association between grade and stage of thrombus (P = 0.011). Using Kaplan朚eier survival analysis, the median overall survival (OS) was 75 (95% confidence interval [CI] = 43.5�6.5) months, and the median recurrence-free survival (RFS) was 48 (95% CI = 33.1�.3) months. Age (P = 0.03), presence of systemic symptoms (P = 0.01), radiological size (P = 0.04), histopathological grade (P = 0.01), level of thrombus (P = 0.04), and invasion of thrombus into IVC wall (P = 0.01) were found to be significant predictors of OS. Conclusion: The management of RCC with IVC thrombus poses a major surgical challenge. Experience of a center along with high-volume and multidisciplinary facility particularly cardiothoracic facility provides better perioperative outcome. Though surgically challenging, it offers good overall-survival and recurrence-free survival

An economic model to assess the value of triclosan-coated sutures in reducing the risk of surgical site infection in a mastectomy in India

Background: The comparison of triclosan-coated sutures (TCS) was made with conventional nonantimicrobial-coated sutures (NCS) to reduce surgical site infection (SSI). This study demonstrates the efficacy and economic outcome of TCS versus NCS for SSIs in mastectomy in India. Methods: In this retrospective analysis, 100 patients were included for both conditions桾CS and NCS梖rom a private and public hospital in India. A systematic literature search of available evidence for both SSI incidences and TCS efficacy data in India were gathered. We collected cost data from a private and public hospital, respectively, for mastectomy in India. The cost-effectiveness of TCS in comparison with the conventional NCS was calculated using a decision-tree deterministic model. We performed a one-way sensitivity analysis to compare TCS with NCS. Results: Cost savings with the use of TCS increased with an increase in SSI incidence and an increase in efficacy for mastectomies in both public and private hospitals. We found a base cost saving of Indian rupees (INR) 27,299 at a private hospital and INR 2,958 at a public hospital for mastectomies. The incremental cost of TCS suture was 0.01% in a private hospital whereas 0.17% in a public hospital. Conclusion: The use of TCS resulted in reduced SSI incidence and cost savings for mastectomy in India.

Lung cancer in the older population: Interactive effects of angiotensin converting enzyme gene polymorphism (rs 4340 ID) and tobacco addiction in risk assessment

Background: rs4340ID polymorphism of angiotensin-converting enzyme (ACE) correlates with serum ACE levels in many known cancers. This study analyzed ACE rs4340 ID polymorphism in lung cancer (LC) in older patients of North India and correlated it with addiction status. Methods: The study enrolled all subjects aged 60 years and above with 154 LC and 205 healthy controls. Genotyping was done by polymerase chain reaction (PCR) and validated by sequencing of 10% of the sample. Statistical analysis was done by SPSS Statistics 21. Results: Genotype II was observed to have a significant 2.21-fold increased risk of LC as compared to the DD genotype and 3.43-folds enhanced risk with interaction of I allele with tobacco consumption habits as compared to D allele in LC was seen. Conclusion: The risk of LC was higher with II genotype as compared to DD genotype. Interactive effect showed that I allele with tobacco habits may increase the risk of LC.

Variation in COVID Mortality with Different Demographic Factors in Districts of India

Background : Descriptive data suggests significant disparity in the COVID-19 related deaths across different demographic zones. Several studies have examined these factors at the intra-country or intrastate level. Our study analyzed the data at a District level. Methods : This cross-sectional study analyzed the association between Socio-demographic factors and COVID19 Mortality at a District level using Univariate and Multivariate linear regression models. Data for sixty randomly selected Districts was collected and compiled from free sources available in the public domain. Linear regression models were built and factors that were found to be significant were used in the model. Results : Univariate analysis revealed that COVID Mortality has a positive correlation with the literacy rate and a negative correlation with the percentage Rural population of the District. No significant relation was found with primary Health Center accessibility, Sex Ratio and the percentage of chronic illness. On Multivariate analysis, it was negatively correlated to only the percentage of the Rural population. Conclusion and Relevance : Our study concluded that as the rural population increased in a district, COVID 19 mortality decreased. There was no significant association with other sociodemographic variables.

Clinical outcomes of MANTA vs suture-based vascular closure devices after transcatheter aortic valve replacement: An updated meta-analysis

Objective: A recently published randomized control trial showed different results with suture-based vascular closure device (VCD) than plug-based VCD in patients undergoing transfemoral transcatheter aortic valve replacement (TAVR). The learning curve for MANTA device is steep, while the learning curve for suture based VCD is shallow as the devices are quite different. In this meta-analysis, we have compared suture-based (ProGlide and Prostar XL) vs plug-based VCDs (MANTA). Methods: We performed a meta-analysis of all published studies (using PubMed/Medline and Cochrane databases) reporting the clinical outcome of plug-based vs suture-based VCDs in transfemoral TAVR patients. Results: We included nine studies with a total of 2865 patients (plug-based n ¼ 1631, suture-based n ¼ 1234). There was no significant difference in primary outcome of all bleeding when using plugbased as opposed to suture-based VCDs (RR 1.14 [0.62e2.06] I2 ¼ 72%). There was no significant difference in the incidence of secondary outcomes between two groups including major life threatening bleeding (RR 1.16 [0.38e3.58] I2 ¼ 65%), major vascular complications (RR 0.84 [0.35e2.00] I2 ¼ 55%), minor vascular complications (RR 1.05 [0.56e1.95] I2 ¼ 42%), pseudo aneurysm (RR 1.84 [0.11e29.98] I 2 ¼ 44%), stenosis-dissection (RR 0.98 [0.66e1.47] I2 ¼ 0%), VCD failure (RR 1.71 [0.96e3.04] I2 ¼ 0%), and blood transfusion (RR 1.01 [0.38e2.71], I2 ¼ 61%). Conclusion: Large bore arteriotomy closure with plug-based VCD was not superior to suture-based VCDs in this transfemoral TAVR population. There was very frequent use of secondary VCDs in suture-based VCD group which is not practical when using MANTA. Additional high-powered studies are required to determine the safety and efficacy of MANTA device.

Comparison of Weight for Height and BMI for Age for Estimating Overnutrition Burden in Under-Five Populations With High Stunting Prevalence

Background: Overnourished under-five children are anthropometrically classified as either being at possible risk of overweight, overweight or obese and defined so, when either weight for height or body mass index for age (BMI-for-age) are >1SD to 2SD, >2SD to 3SD and >3SD, respectively of the analogous World Health Organization standards. Aim: To compare weight for height and BMI for age definitions for quantifying overnutrition burden. Methods: Theoretical consequences of ignoring age were evaluated by comparing, at varying height for age z-scores, the age- and sex-specific cutoffs of BMI that would define overnutrition with these two metrics. Overnutrition prevalence was then compared in simulated populations (short, intermediate and tall) and real-life datasets from India. Results: In short (-2SD) children, the BMI cutoffs with weight for height criteria were lower in comparison to BMI for age till 7-8 months, but higher at later ages. In National Family Health Survey-4, India dataset (short population), overnutrition (>1SD) prevalence with weight for height was higher from 0-0.5 years (exclusive breastfeeding age), but lower at subsequent ages. The prevalence difference (weight for height - BMI for age) in 0.5-5 years was -2.26% (6.57% vs 8.83%); this attenuated in 0-5 years (-1.55%; 7.23% vs 8.78%). The discrepancy was maximal for stunted children and was lower in girls. A similar pattern, of lower magnitude, was observed for overweight (>2SD) comparison. In intermediate and tall populations, there were no meaningful differences. Conclusion: The two definitions produce cutoffs, and hence estimates of overnutrition, that differ with the age, sex, and height of under-five children. The relative invariance, with age and height, of BMI for age, favors its use.

Heart Smart Diabetes Care

The world is growing smarter day by day, and so is health care. In spite of innumerable inventions and tech-tools, however, we struggle to contain chronic illnesses like diabetes and heart disease. We need to work together and design a rational, scientific and socially sustainable Heart Smart diabetes care ecosystem, with Heart Smart management strategies, to ensure happiness and harmony in persons who live with diabetes.
