Refractive error and amblyopia among primary school children in remote islands of East Coast of Peninsular Malaysia.

INTRODUCTION: Little is known about the prevalence of refractive errors and amblyopia among school children on the islands of East Coast Malaysia. This study aimed to investigate the prevalence of these conditions and their associated factors in this unique and remote geographical location. MATERIALS AND METHODS: This multicentre cross-sectional school-based study included 480 children aged 7 to 12 year from primary schools on the islands of the East Coast of Malaysia. All children underwent visual acuity assessment, orthoptic evaluation, anterior and posterior segment examinations and manifest refraction. Demographic data, history of parental refractive error, parental education level, duration of digital screen time and time spent outdoors were documented in a questionnaire distributed to the parents. RESULTS: The mean age was 9.53 ± 1.69 years, with an equal distribution of genders. The ethnic composition of the subjects was 99.4% Malay and 0.6% Orang Asli. The overall prevalence of refractive errors was 11.9% (95% CI: 9.1 to 15.1%), with myopia at 7.1% (95% CI: 5.0 to 9.8%), hyperopia at 2.5% (95% CI: 1.3 to 4.3%), astigmatism at 2.3% (95% CI: 1.1 to 4.1%) and amblyopia at 2.5% (95% CI: 1.3 to 4.3%). Older age, an absence of parental history of refractive error and reduced daily outdoor time were significantly associated with refractive errors (p < 0.05). CONCLUSION: The prevalence of refractive error is 11.9% and amblyopia is 2.5% among primary school children on the islands of the East Coast of Peninsular Malaysia. Older age, an absence of parental history of refractive error and reduced daily outdoor time are associated with refractive error.

Efficacy of periarticular local infiltrative anaesthesia (modified Ranawat cocktail regimen) for postoperative pain control and reducing morbidity in total knee arthroplasty: a tertiary centre retrospective study.

INTRODUCTION: surgical pain is managed with multi-modal anesthesia in total knee arthroplasty (TKA). It is dubious whether including local infiltrative anaesthesia (LIA) before wound closure provides adequate pain control and decreases morbidity. MATERIAL AND METHODS: this was a retrospective conducted to assess postoperative pain control, morbidity index, and opioid consumption in 116 patients who underwent TKA and were divided into two groups based on LIA (Modified Ranawat Regimen) or normal saline infiltration in the wound. RESULTS: the mean NRS score was significantly lower in LIA group (3.2) as compared to the control group (3.9) in the first 24 hours. Functional milestones were relatively achieved earlier in LIA group but the values were not significant. Tramadol consumption was remarkably higher in the control group as compared to LIA group on day 1 and 2. As per the morbidity index the mean score on day one was 16.18 and 23.40 which decreased to 6.37 and 9.21 by day three in LIA and control group respectively indicating morbidity has decreased but more so in LIA group. CONCLUSION: our study concludes that use of modified cocktail regimen in the knee effectively decreased morbidity with excellent to good results, declining NRS score, minimal rescue analgesia requirement, early ambulation with better safety.

INTRODUCCIÓN: el dolor quirúrgico se trata con anestesia multimodal en la artroplastia total de rodilla (ATR). Es dudoso que incluir anestesia local infiltrativa (LIA) antes del cierre de la herida proporcione un control adecuado del dolor y disminuya la morbilidad. MATERIAL Y MÉTODOS: se realizó una retrospectiva para evaluar el control del dolor posoperatorio, el índice de morbilidad y el consumo de opioides en 116 pacientes sometidos a ATR y se dividieron en dos grupos según el LIA (régimen de Ranawat modificado) o la infiltración de solución salina normal en la herida. RESULTADOS: la puntuación media NRS fue significativamente menor en el grupo LIA (3.2) en comparación con el grupo control (3.9) en las primeras 24 horas. Los hitos funcionales se alcanzaron relativamente antes en el grupo LIA, pero los valores no fueron significativos. El consumo de tramadol fue notablemente mayor en el grupo de control en comparación con el grupo de LIA los días 1 y 2. Según el índice de morbilidad, la puntuación media el día uno fue 16.18 y 23.40, que disminuyó a 6.37 y 9.21 en el día tres en el grupo de LIA y control, respectivamente, lo que indica que la morbilidad ha disminuido, pero más en el grupo LIA. CONCLUSIÓN: nuestro estudio concluye que el uso de un régimen de cóctel modificado en la rodilla disminuyó efectivamente la morbilidad con resultados excelentes a buenos, una disminución de la puntuación NRS, un requisito mínimo de analgesia de rescate y una deambulación temprana con mayor seguridad.

Morpho-molecular characterisation of two new and two previously reported species of Acanthogyrus (Acanthogyrus: Quadrigyridae) from freshwater fishes in India.

Of the total 47 species in the subgenus Acanthosentis, 43 have been reported from the freshwater fishes of Asia. Amin et al. (2017) provided a key to the 23 species of the genus Acanthogyrus reported from the Indian subcontinent. The present study reports two new species: Acanthogyrus bispinosa n. sp. and A. garciai n. sp. from Cirrhinus mrigala Hamilton and Labeo calbasu Hamilton, respectively, and two previously described species: A. golvani Gupta and Jain, 1980 and A. hereterospinus Khan and Bilqees, 1990 from L. rohita Hamilton and L. catla Hamilton, respectively. A. bispinosa n. sp. comprises 3 circles of 6 proboscis hooks each. Trunk spines in A. bispinosa n. sp are divided into two groups: anterior and posterior separated by unarmed region, which has not been previously reported in the subgenus. Anterior spines are present in 7-8 and 7-10 circles in females and males, respectively, whereas posterior spines are in 23-28 and 31-38 circles in males and females, respectively. A. garciai n. sp. comprises 3 circles of 6-8 hooks each and a single set of trunk spines is present in A. garciai n. sp., comprising 35-42 and 25-45 circles in males and females, respectively. All four species were also characterised based on the 18S, 28S, and ITS1-5.8S-ITS2 rRNA molecular markers. The Bayesian inference tree generated based on these markers showed distinct identities of all the species, with a significant molecular divergence, ranging from 3.2 to 53.6%.

Outcomes of TB contact tracing and predictors of success: a 10-year retrospective cohort analysis in Birmingham, UK.

BACKGROUND: Contacts of TB cases in Birmingham and Solihull, UK, are offered screening for TB infection. Between 1990 and 2010, only 59.1% of contacts completed screening. The service has since increased screening staff numbers, changed screening locations and increased screening follow-up. Our primary aim was to identify whether screening completion rates have improved. Our secondary aim was to identify predictors of screening completion.METHODS: This was a retrospective analysis of all contacts of TB patients in Birmingham and Solihull between 1 January 2011 and 31 December 2020, stratified by pulmonary and extrapulmonary TB (PTB or EPTB) index infection. Multiple logistic regression analysis for predictors of screening completion was performed.RESULTS: A total of 3,255 index cases and 27,820 contacts were identified. TB incidence has declined, in keeping with national trends. Screening completion has improved from 59.1% of contacts to 74.9% overall since service improvements were made, with improvement in screening completion for contacts of both PTB and EPTB index cases (OR 1.087, 95% CI 1.074-1.101; P < 0.001) and (OR 1.048, 95% CI 1.019-1.078; P = 0.001), respectively.CONCLUSIONS: Changes made to the TB service have improved screening outcomes over the last decade. Significant predictors of screening completion have been identified, highlighting areas for targeted resource allocation.

Evaluation of hospital environment for presence of Mucorales during COVID-19-associated mucormycosis outbreak in India - a multi-centre study.

BACKGROUND: An unprecedented rise in the number of COVID-19-associated mucormycosis (CAM) cases has been reported in India. Myriad hypotheses are proposed for the outbreak. We recently reported uncontrolled diabetes and inappropriate steroid therapy as significant risk factors for the outbreak. However, Mucorales contamination of hospital environment was not studied. AIM: To perform a multi-centre study across India to determine possible Mucorales contamination of hospital environment during the outbreak. METHODS: Eleven hospitals from four zones of India representing high to low incidence for mucormycosis cases were included in the study. Samples from a variety of equipment used by the patients and ambient air were collected during May 19th, 2021 through August 25th, 2021. FINDINGS: None of the hospital equipment sampled was contaminated with Mucorales. However, Mucorales were isolated from 11.1% air-conditioning vents and 1.7% of patients' used masks. Other fungi were isolated from 18% of hospital equipment and surfaces, and 8.1% of used masks. Mucorales grew from 21.7% indoor and 53.8% outdoor air samples. Spore counts of Mucorales in air were significantly higher in the hospitals of North and South zones compared to West and East zones (P < 0.0001). Among Mucorales isolated from the environment, Rhizopus spp. were the most frequent genus. CONCLUSION: Contamination of air-conditioning vents and hospital air by Mucorales was found. Presence of Mucorales in these areas demands regular surveillance and improvement of hospital environment, as contamination may contribute to healthcare-associated mucormycosis outbreaks, especially among immunocompromised patients.

Understanding the building blocks of the paediatric dentistry curriculum for undergraduate students in an Australian University.

PURPOSE: To investigate the attitude of final-year dental students towards their paediatric dentistry training and their confidence in treating child patients. METHODS: A 55-item questionnaire was distributed online and physically to the final-year BDSc (Hons) students at The University of  Queensland (Australia). The questionnaire consisted of four parts including theoretical knowledge, clinical observational experience, preclinical training and clinical training in paediatric dentistry. Self-reported confidence was recorded using five-point Likert scale questions ranging from 'not confident at all' to 'completely confident', which were allocated the numbers 1-5, respectively. Jamovi and GraphPad Prism were used for data analysis and creation of graphs. RESULTS: A total of 47 students completed the questionnaire giving a response rate of 77%. Approximately two-thirds of participants had previous experience working with children and 70% had observed a practitioner providing paediatric dental treatment. The students reported the lowest level of clinical confidence for pulp therapy (M = 2.32; SD = 1.08). The clinical confidence in dental trauma management was also reported to be low (M = 2.50; SD = 1.15). The clinical administration of local anaesthetic (LA) had the highest level of confidence (M = 3.95; SD = 1.03). The students reported that they were highly confident in the theoretical knowledge of behaviour guidance techniques (M = 3.64; SD = 0.97) and preclinical training involving examination, treatment planning and preventative procedures (M = 4.33, SD = 0.67). CONCLUSION: This study showed that students reported low levels of confidence in pulp therapies and trauma management in children as compared to other aspects of paediatric dentistry. Students indicated the need for more preclinical and clinical training sessions, as well as more opportunities to perform a wider variety of treatments on paediatric patients.

Universal use of surgical masks is tolerated and prevents respiratory viral infection in stem cell transplant recipients.

Prevention of respiratory viral infection in stem cell transplant patients is important due to its high risk of adverse outcome. This single-centre, mixed methods study, conducted before the severe acute respiratory syndrome coronavirus-2 pandemic, explored the barriers and facilitators to a policy of universal mask use by visitors and healthcare workers, and examined the impact of the first year of introduction of the policy on respiratory viral infection rates compared with preceding years, adjusted for overall incidence. Education around universal mask use was highlighted as being particularly important in policy implementation. A significant decrease in respiratory viral infection was observed following introduction.

DNA banking, its current awareness and national status in biomedical research in India, a survey.

A Biobank/Biorepository is an organized collection of resources that can be accessed to retrieve biological material and data for research purpose. Human specimen repositories (adult and paediatric) take lead amongst the various types of biorepositories. Patient's bio samples are a rich source of genetic information and therefore can form the basis of diagnostics, forensics and multidimensional disciplines of biomedical research. The advent of molecular techniques and the technological upsurge in the management of genetic resources has facilitated the human DNA sampling and data collection leading to the emergence of DNA banking. DNA banking has paved a new path in precision oncology and personalized medicine. This article highlights the current scenario concerning the general awareness, scientific consciousness and current national and international practices being initiated and in practice for the establishment of bio banking facilities particularly DNA bio banking.

Hydrogen sulphide and salicylic acid regulate antioxidant pathway and nutrient balance in mustard plants under cadmium stress.

Cadmium (Cd), a pervasive noxious heavy metal, is a key threat to agricultural system. It is rapidly translocated and has detrimental effects on plant growth and development. Hydrogen sulphide (H2 S) is emerging as a potential messenger molecule for modulating plant tolerance to Cd. Salicylic acid (SA), a phenolic signalling molecule, can alleviate Cd toxicity in plants. The present study investigated the mediatory role of H2 S (100 µM) and SA (0.5 mM), individually and in combination, in modulating antioxidant defence machinery and nutrient balance to impart Cd (50 µM) resistance to mustard. Accumulation of Cd resulted in oxidative stress (TBARS and H2 O2 ), mineral nutrient imbalance (N, P, K, Ca), decreased leaf gas exchange and PSII efficiency, ultimately reducing plant growth. Both H2 S and SA independently attenuated phytotoxic effects of Cd by triggering antioxidant systems, enhancing the nutrient pool, eventually leading to improved photosynthesis and biomass of mustard plants. The positive effects were more pronounced under combined application of H2 S and SA, indicating a synergistic relationship between these two signalling molecules in mitigating the detrimental effects of Cd on nutrient homeostasis and overall health of mustard, primarily by boosting antioxidant pathway. Our findings provide new insights into H2 S- and SA-induced protective mechanisms in mustard plants subjected to Cd stress and suggest their combined use as a feasible strategy to confer Cd tolerance.

Serotype and genotype diversity of dengue viruses circulating in India: a multi-centre retrospective study involving the Virus Research Diagnostic Laboratory Network in 2018.

OBJECTIVES: A retrospective study was undertaken to investigate the circulating dengue virus (DENV) serotypes and genotypes in India in 2018. METHODS: In total, 4963 samples referred to virus research diagnostic laboratories (n=21), the Indian Council of Medical Research-National Institute of Virology (ICMR-NIV) and ICMR-NIV field units (n=2) for diagnosis of dengue in 2018 were tested using a real-time reverse transcription polymerase chain reaction assay for the presence of DENV serotypes. Representative samples were sequenced for the envelope (E) gene. RESULTS: Regional diversity was observed with regard to the dominant circulating serotypes. DENV-2 was found to be the most common serotype in many states. Thrombocytopenia, petechiae and malaise were associated with DENV-2 infection. Phylogenetic analyses of DENV E gene sequences revealed the circulation of genotypes I and V of DENV-1, two lineages of DENV-2 genotype IV, DENV-3 genotype III and DENV-4 genotype I. CONCLUSIONS: This study found regional differences in the prevalence of circulating DENV serotypes in India, and provides baseline data for continuous molecular surveillance. Molecular surveillance may have implications for predicting large-scale outbreaks of dengue if regional shifts in the predominantly circulating serotypes and genotypes are detected during the early phase of the dengue season.

Lactobacillus fermentum (MTCC-5898) alleviates Escherichia coli-induced inflammatory responses in intestinal epithelial cells by modulating immune genes and NF-κB signalling.

AIM: Dietary intervention using probiotic bacteria has emerged as a promising preventive strategy in addressing foodborne infections or gastrointestinal disorders. This study investigated the immunomodulatory effects of Lactobacillus fermentum (MTCC-5898) on Escherichia coli-induced inflammatory responses in intestinal epithelial cells. METHODS AND RESULTS: The immune response of intestinal cells (Caco-2) in the presence of probiotic Lact. fermentum was determined during exclusion, competition and displacement of E. coli as the inflammatory agent. To achieve this objective, transcriptional modulation of key immune-related genes (cytokines, pattern recognition receptors and NF-κB), release of cytokines and nuclear translocation of the NF-κB subunit p-65 were studied. Expression of pro-inflammatory cytokines IL-8, TNF-α, IFN-ϒ and IL-23 was high in E. coli-exposed intestinal cells. However, overexpression of these E. coli-induced pro-inflammatory cytokines was prevented by Lact. fermentum during exclusion and competition assays. It also modulated the transcriptional expression of regulatory cytokines (IL-10 and TGF-ß), pattern recognition receptors (TLR-2 and TLR-4) and genes associated with master inflammatory regulators (NF-κB and SIGIRR) to reduce E. coli-induced inflammation. The protective effect of Lact. fermentum was further confirmed by suppression of nuclear translocation of cytoplasmic NF-κB subunit (p-65). CONCLUSION: Lactobacillus fermentum alleviated E. coli-induced inflammatory responses by modulating the NF-κB signalling besides pro-inflammatory and regulatory cytokines expression. SIGNIFICANCE AND IMPACT OF THE STUDY: Lactobacillus fermentum holds significant promise as a potent nutraceutical that prevents and manages inflammatory gut-associated dysfunctions.

Comparative effectiveness of antiretroviral drug classes for the treatment of HIV infection in patients with high viral loads: a multicentre retrospective cohort study.

OBJECTIVES: We aimed to compare the effectiveness of antiretroviral therapy (ART) classes for achieving HIV RNA suppression to < 50 HIV-1 RNA copies/mL within 6 months of initiation with high viral loads (VLs). Secondary objectives were to compare viral suppression (VS) at 12 weeks and 12 months, partial HIV RNA suppression to < 200 copies/mL, time to VS, time to rebound, and change in CD4 cell count. METHODS: This was a multicentre, retrospective, observational study. Adult patients were included if they initiated ART between January 2005 and December 2016 with a VL ≥ 100 000 copies/mL. RESULTS: There were 220 patients included in the study. The median VL was 252 919 [interquartile range (IQR) 149 472-500 000] copies/mL. Nonnucleoside reverse transcriptase inhibitor (NNRTI) recipients were more likely to achieve VS by 6 months compared to those initiating ART containing protease inhibitors (PIs) [75.4% vs. 44.1%, respectively; odds ratio (OR) 3.34; 95% confidence interval (CI) 1.62-6.90] or integrase strand transfer inhibitors (INSTIs) (75.4% vs. 55.8%, respectively; OR 2.40; 95% CI 1.03-5.58). VS at 12 weeks was more frequent with INSTI-containing regimens than with PIs (28.9% vs. 9.0%, respectively; OR 4.10; 95% CI 1.69-9.92). VS at 12 months did not significantly differ between treatment regimens. Median time to complete VS for INSTI, PI and NNRTI recipients was 22.3 (95% CI 13.4-33), 30.1 (95% CI 25-36) and 19.9 (95% CI 16-22.3) weeks, respectively. There were no significant differences in time to viral rebound or change in CD4 cell counts. CONCLUSIONS: Patients with high VLs initiated on NNRTIs were more likely to achieve VS by 6 months on ART compared to INSTI and PI recipients.

Robotic lateral pelvic lymph node dissection after chemoradiation for rectal cancer: a Western perspective.

AIM: There are limited outcome data for lateral pelvic lymph node dissection (LPLND) following neoadjuvant chemoradiotherapy (nCRT), particularly in the West. Our aim was to evaluate the short-term perioperative and oncological outcomes of robotic LPLND at a single cancer centre. METHOD: A retrospective analysis of a prospective database of consecutive patients undergoing robotic LPLND for rectal cancer between November 2012 and February 2020 was performed. The main outcomes were short-term perioperative and oncological outcomes. Major morbidity was defined as Clavien-Dindo grade 3 or above. RESULTS: Forty patients underwent robotic LPLND during the study period. The mean age was 54 years (SD ± 15 years) and 13 (31.0%) were female. The median body mass index was 28.6 kg/m2 (IQR 25.5-32.6 kg/m2 ). Neoadjuvant CRT was performed in all patients. Resection of the primary rectal cancer and concurrent LPLND occurred in 36 (90.0%) patients, whilst the remaining 4 (10.0%) patients had subsequent LPLND after prior rectal resection. The median operating time was 420 min (IQR 313-540 min), estimated blood loss was 150 ml (IQR 55-200 ml) and length of hospital stay was 4 days (IQR 3-6 days). The major morbidity rate was 10.0% (n = 4). The median lymph node harvest from the LPLND was 6 (IQR 3-9) and 13 (32.5%) patients had one or more positive LPLNs. The median follow-up was 16 months (IQR 5-33 months), with 1 (2.5%) local central recurrence and 7 (17.5%) patients developing distant disease, resulting in 3 (7.5%) deaths. CONCLUSION: Robotic LPLND for rectal cancer can be performed in Western patients to completely resect extra-mesorectal LPLNs and is associated with acceptable perioperative morbidity.

Robotic rectal cancer surgery: comparative study of the impact of obesity on early outcomes.

The aim of this study was to compare the outcomes of robotic total mesorectal excision (TME) in obese versus non-obese patients. A total of 533 patients, of whom 161 were obese (30·2 per cent) underwent robotic proctectomy during the study interval. Patient obesity was not associated with adverse short-term clinical outcomes after robotic rectal cancer surgery. Indicated in the obese perhaps?

A multicentre observational study on the epidemiology, risk factors, management and outcomes of mucormycosis in India.

OBJECTIVES: To describe the epidemiology, management and outcome of individuals with mucormycosis; and to evaluate the risk factors associated with mortality. METHODS: We conducted a prospective observational study involving consecutive individuals with proven mucormycosis across 12 centres from India. The demographic profile, microbiology, predisposing factors, management and 90-day mortality were recorded; risk factors for mortality were analysed. RESULTS: We included 465 patients. Rhino-orbital mucormycosis was the most common (315/465, 67.7%) presentation followed by pulmonary (62/465, 13.3%), cutaneous (49/465, 10.5%), and others. The predisposing factors included diabetes mellitus (342/465, 73.5%), malignancy (42/465, 9.0%), transplant (36/465, 7.7%), and others. Rhizopus species (231/290, 79.7%) were the most common followed by Apophysomyces variabilis (23/290, 7.9%), and several rare Mucorales. Surgical treatment was performed in 62.2% (289/465) of the participants. Amphotericin B was the primary therapy in 81.9% (381/465), and posaconazole was used as combination therapy in 53 (11.4%) individuals. Antifungal therapy was inappropriate in 7.6% (30/394) of the individuals. The 90-day mortality rate was 52% (242/465). On multivariate analysis, disseminated and rhino-orbital (with cerebral extension) mucormycosis, shorter duration of symptoms, shorter duration of antifungal therapy, and treatment with amphotericin B deoxycholate (versus liposomal) were independent risk factors of mortality. A combined medical and surgical management was associated with a better survival. CONCLUSIONS: Diabetes mellitus was the dominant predisposing factor in all forms of mucormycosis. Combined surgical and medical management was associated with better outcomes. Several gaps surfaced in the management of mucormycosis. The rarer Mucorales identified in the study warrant further evaluation.

Hand hygiene compliance of patients' family members in India: importance of educating the unofficial 'fourth category' of healthcare personnel.

INTRODUCTION: In India, due to manpower constraints, patients' family members are often actively involved in healthcare activities of their near and dear ones. They have significant contact with the patient at all World Health Organization (WHO) 'five moments for hand hygiene'. This study analysed the impact of decade-long awareness campaigns on the hand hygiene compliance (HHC) by our patients' carers. METHODS: Trained infection control nurses observed the HHC at each of the five moments for patients' attendants in different hospital settings from January 2014 to December 2018. Compliance was calculated as percentage of events divided by total opportunities. FINDINGS: A total of 7302 opportunities were observed with an overall compliance of 46.1% (35.5% in 2014 to 48.2% in 2018, P < 0.0001). Compliance at WHO moments 1, 2, 3, 4, and 5 was 51.0%, 47.4%, 67.6%, 48.8%, and 24.3% respectively. Among family members, mothers of newborns had a much higher HHC (77%) than others (44.5%) (P < 0.0001). Also, the compliance was higher in medical versus surgical wards and in paediatric wards versus adult wards (P < 0.0001 in both). CONCLUSION: This is the first study on family members' HHC in a hospital setting in a low- and middle-income country. The study shows that family members, once trained, exhibit fairly good HHC while caring for their patients, especially mothers of newborns. It is worthwhile empowering and educating patient attendants about the importance and process of hand hygiene as it is likely to result in immense benefit for patients.

Selective central vascular ligation (D3 lymphadenectomy) in patients undergoing minimally invasive complete mesocolic excision for colon cancer: optimizing the risk-benefit equation.

AIM: Complete mesocolic excision (CME) with central vascular ligation (CVL) has been advocated for right colon adenocarcinoma (RC), but the radicality of vascular dissection remains controversial. Our aim is to report outcomes of selective CVL (D3 lymphadenectomy) during minimally invasive CME for RC. METHOD: A prospective database identified patients who were treated for RC between 2009 and 2016. Minimally invasive CME was standard. The radicality of lymphadenectomy was defined as high ligation (HL) versus CVL based on operative reports and videos. Two blinded radiologists independently evaluated the pre- and postoperative CT scans for radiographically abnormal nodes. RESULTS: Of 197 patients who underwent CME, HL was performed in 56 (28%) and CVL in 141 (72%). There were no baseline differences in age, sex, body mass index, American Society of Anesthesiologists score or pathological staging, and there were no major intra-operative complications in either group (including no major vascular injuries). The median total number of nodes retrieved was 27 and 31 (P = 0.011) in HL and CVL groups, resepctively, with pathologically positive nodes identified in 33.9% and 39.8% (P = 0.704), respectively. Preoperative imaging identified abnormal cN3 nodes in 1.5% of patients; all of whom underwent CVL. No abnormal cN2 or cN3 nodes remained on postoperative imaging. The 60-day mortality was 0.5%, and major morbidity was 4%. One patient (0.5%) had an anastomotic recurrence after a median follow-up of 22 months. CONCLUSION: With imperfect preoperative clinical nodal staging, and in the absence of randomized data, the low morbidity and oncological outcomes observed support the approach of CME with HL as a minimum standard, with CVL (D3 lymphadenectomy) in selected cases.

Cladosporium sphaerospermum causing brain abscess, a saprophyte turning pathogen: Case and review of published reports.

Emergence of saprophytic fungi thriving in dead plant material and soil as opportunistic human pathogens is of great concern. Cladosporium species are environmental saprophytes reported to cause various superficial and invasive fungal infections worldwide. C. sphaerospermum, a predominantly indoor fungus has been reported from cases of meningitis, subcutaneous and pulmonary fungal infections in the past. Herein we report the first case of cerebral abscess due to C. sphaerospermum in an immunocompetent host who was successfully managed by combined medical and surgical therapy.
