ABSTRACT
Objective To assess the risk of nosocomial infection in patients with multiple myeloma during their first hospitalization. Methods Totally 480 patients with multiple myeloma who were hospitalized for the first time in department of hematology of West China Hospital, Sichuan University from August 2021 to August 2022 were included, and the nosocomial infection during treatment was statistically analyzed. The patients were divided into infected group and uninfected group. The independent influencing factors of nosocomial infection were analyzed and a prediction model was established. The reliability of the prediction model was analyzed by receiver operating characteristic curve (ROC). Results The incidence rate of nosocomial infection was 31.2% among 480 patients hospitalized for the first time. There were statistically significant differences in age, ISS staging, controlling nutritional status (CONUT) score, agranulocytosis, hemoglobin, and albumin between the infected group and the uninfected group (P<0.05). Logistic multivariate regression analysis showed that age, ISS staging, CONUT score, agranulocytosis, hemoglobin level, and albumin level were all independent correlated factors of nosocomial infection in patients with multiple myeloma hospitalized for the first time (P<0.05). The area under the ROC curve (AUC), sensitivity and specificity of multivariate logistic regression prediction model were 0.88 (95%CI: 0.840-0.920), 85.00% and 76.36%, respectively. Conclusion The incidence rate of nosocomial infection is high among patients with multiple myeloma in the first hospitalization. The prediction model established according to independent correlated factors of nosocomial infection has high predictive value on the occurrence of nosocomial infection.
ABSTRACT
AIM: To investigate the differences in varying stages of non-proliferative diabetic retinopathy(NPDR)using optical coherence tomography angiography(OCTA).METHODS: Cross-sectional study. A total of 77 cases(77 eyes)of diabetic patients were included, and they were divided into non-diabetic retinopathy(NDR; 23 eyes)and non-proliferative diabetic retinopathy(NPDR; 54 eyes)groups, further subdivided into mild NPDR(20 eyes), moderate NPDR(20 eyes), and severe NPDR(14 eyes). Foveal avascular zone(FAZ)area, superficial and deep capillary plexus densities(SSP and DSP), and visual acuity(LogMAR)were compared between NDR and NPDR groups. Furthermore, the visual acuity, FAZ area and levels of SSP and DSP were compared in different degrees of NPDR. Correlation analysis were conducted to elucidate relationships between FAZ area, visual acuity, SSP, DSP, and severity of the disease.RESULTS: Compared with the NDR group, the visual acuity(LogMAR)and macular FAZ area increased, while SSP and DSP were decreased in the NPDR group(P&#x003C;0.05); there were significant differences in visual acuity, FAZ area and SSP and DSP levels in different degrees of NPDR(P&#x003C;0.05). Visual acuity(LogMAR)and FAZ area displayed a positive correlation with the severity of disease, while SSP and DSP showed a negative correlation.CONCLUSION: With the progression of NPDR, the visual acuity(LogMAR)and FAZ area increased, and the SSP and DSP decreased.
ABSTRACT
Abstract Objective: To describe the challenges pediatric dentists face while caring for their patients during the pandemic. Material and Methods: A descriptive qualitative study was conducted with purposefully sampled pediatric dentists. Data were collected through in-depth, semi-structured interviews until the content of the collected data reached theoretical saturation. Data were transcribed verbatim, coded, and analyzed using content analyses. Results: Seven participants (four females and three males) between 29 and 50 years participated in the study. Three themes emerged from the analyses: Anxiety and fear; PPE (Personal Protective Equipment) and its impact on care delivery; and 3) Behavior management. Conclusion: Dental care delivery was challenging for pediatric dentists. They experienced high anxiety levels and modified their services according to the recommended guidelines while making accommodations to lessen patients' COVID-19-related anxiety. The additional mandated PPE use affected the communication between the dentists and their patients, affecting their dentist-patient bonding.

Primary central nervous system diffuse large B-cell lymphoma (PCNS-DLBCL) is an uncommon extranodal lymphoma that accounts for more than 95% of all the CNS lymphomas. Unlike its systemic/nodal counterpart, which is currently subtyped into cell-of origin (COO) subtypes, its feasibility and utility are largely debatable in PCNS-DLBCL. Objectives: To classify PCNS-DLBCL into COO-subtypes based on immunohistochemical algorithms by Hans and Choi and evaluate concordance between the two. A further aim is to investigate the clinicoradiological and histomorphological parameters of the subtypes thus obtained. Materials and Methods: As many as 143 cases of primary CNS lymphoma were evaluated by immunohistochemistry for CD10, BCL6, MUM1, GCET, and FOXP1 and based on which the said 143 cases were further classified into COO subtypes using Hans and Choi algorithms. Results: Mean age was 53.8 years with marginal male preponderance and predominantly centroblastic morphology (75.5%). CD 10 was positive in 8.9% of the cases, BCL6 in 58.6%, MUM1 in 89.9%, GCET in 32.9%, and FOXP1 in 79.5%. As much as 84.9% cases were of non-germinal center B-cell (GCB) subtype and 15.1% cases were of GCB subtype as determined based on Hans algorithm. Furthermore, 90.7% cases were of activated B-cell (ABC) subtype and 9.3% cases were of GCB subtype according to Choi algorithm. A 91.8% concordance was observed between Hans and Choi algorithms. Among the 6 discordant cases, 5 cases were subtyped as GCB by Hans and ABC by Choi and 1 case as ABC by Hans and GCB by Choi. Conclusion: Most of PCNS-DLBCLs are of non-GCB/ABC COO subtype, but inconsistences abound in the utility of IHC algorithms in PCNS-DLBCL COO subtypes.
ABSTRACT
Context: Oral squamous cell carcinoma (OSCC) comprises more than 90% of oral cancers and is the most common carcinoma affecting the oral cavity. Early stage T1/T2 OSCC have a heterogeneous prognosis and a significant number of patients develop loco regional recurrence (LRR) and have reduced disease free survival (DFS) with increased disease related mortality. Aims and Objectives: To assess the impact of the three parameters used in Brandwein-Gensler risk model along with lympho-vascular invasion (LVI), depth of invasion (DOI) and lymph node metastases in predicting LRR in early stage OSCC. Materials and Methods: This was a retrospective study on early stage T1/2 OSCC patients over a period of 2 years who received treatment by surgical resection and had follow-up data. LRR was assessed based on recurrence of OSCC at the initial site or in regional lymph nodes. Results: Out of 1135 OSCC cases during our study period a total of 207 cases befitted our inclusion criteria. Recurrence was noted in 113 (54.6%) cases. Univariate analysis identified LVI (P < 0.00001), DOI (P < 0.00001), nodal involvement (P < 0.00001), worst pattern of invasion (WPOI) (P < 0.00001), lymphocytic host response (LHR) (P = 0.004), perineural invasion (PNI) (P = 0.012) as strong statistically significant risk factors for LRR. Conclusion: Adequate assessment of simple parameters on routine H and E by incorporating Brandwein-Gensler histological risk scoring model at the initial presentation can help prognosticate and predict LRR and select patients for post-surgical adjuvant therapy.
ABSTRACT
The International League Against Epilepsy (ILAE) task force on neonatal seizures has recently published draft guidelines and consensusbased recommendations on the treatment of neonatal seizures. This update provides a summary of the recommendations and the changes in management compared to the previous WHO ILAE guidelines, published in 2011, with emphasis on practical decision making requirements for a pediatrician.
ABSTRACT
Objectives: We studied the modifiable prognostic factors that extend native liver survival at 2 years after Kasai portoenterostomy (KPE). Methods: We reviewed hospital records of patients with neonatal cholestasis, with focus on infants diagnosed with biliary atresia in a tertiary care hospital between January, 2014 and May, 2021. We determined the association of outcome with clinical and laboratory variables. Results: Infants who underwent KPE at a median (IQR) age of 76 (72-79) days had best outcomes, with minimal severe post-KPE complications and 2- year survival rate of 84.6%, compared to other infants (younger and older age at KPE). The median (IQR) weight at KPE in this group was 4.66 (4.2, 5.0) kg. Conclusions: In contrast to traditional recommendations, babies with median age at KPE of 76 days had superior native liver survival (84.6%) and reduced post-KPE complications, as compared to earlier KPE age. Nutritional status and weight of infant at KPE could be associated with this survival difference. This observation needs confirmation through multicentric prospective studies in different settings.
ABSTRACT
ABSTRACT Objective: The recurrent laryngeal nerve (RLN) may be involved by papillary thyroid carcinoma ≤ 1 centimeter (PTC ≤ 1 cm). Current study investigated the predictive factors of RLN invasion in PTC ≤ 1 cm, the risk factors of disease recurrence in RLN invaded cases and the results of surgical management for RLN invasion. Materials and methods: Data of 374 PTC ≤ 1 cm patients were retrospectively collected. We performed univariate and multivariate analysis to identify predictive factors of RLN invasion and risk factors of disease recurrence. The abilities of factors in predicting RLN invasion were evaluated. Surgical outcomes and recurrence free survival (RFS) of patients were analyzed. Results: A total of 28 patients suffered RLN invasion, among which seven had disease recurrence. Preoperative vocal cord palsy (VCP), gross extrathyroidal extension, larger tumor size and tumor on the dorsal side of thyroid were verified as predictive factors of RLN invasion. RLN involved patients had poorer RFS, but better than those who also had upper-aerodigestive tract invasion. Upper-aerodigestive tract invasion, lateral neck lymph nodes metastasis (LNM) and BRAF V600E mutation were independent risk factors of disease recurrence in RLN invaded cases. Tumor shaving showed better RLN function preservation without increasing recurrent risk. Conclusions: Current study confirmed the rarity of RLN invasion in PTC ≤ 1 cm. Various aggressive features were verified as predictive factors of RLN invasion. Tumor shaving showed superiority in preserving nerve function without increasing recurrent risk. Special attentions should be paid for disease recurrence when RLN invasion accompanied by upper-aerodigestive tract invasion, lateral neck LNM or BRAF V600E mutation.
ABSTRACT
Introduction: The external laryngeal nerve passes through the “space of Reeve” cricothyroid space. It has also been described as lying in the Joll’s triangle. It is often inadvertently neglected during thyroid surgeries. It has been named after a singer who lost her voice after a thyroid surgery, as the “nerve of Galli Curci” Aim: To identify the dangerous length of the external laryngeal nerve in relation to the thyroid pole. Material and Methods: Fifty laryngeal nerves were dissected using conventional method of dissection, in twentyfive embalmed cadavers used for teaching purpose at Karpaga Vinayaga Institute of Medical Sciences and Research, Madurantakam. The observations were noted and photographs taken. The course and relations were carefully noted. Results: 38 specimens (76%) had the superior laryngeal nerve measuring 4cm. in 8 specimens (16%) it was 3.5 cm and in 04 specimens (8%) it measured 3.8 cm. It was observed that the external laryngeal nerve crossed the superior thyroid pole at less than 1cm only in three (6%) of the fifty nerves. Conclusions: The critical length of the nerve would be dangerous if the nerve crosses the superior thyroid pedicle close to thyroid pole at less than 1 cm. The consequences of neglecting the critical length would injure the nerve and cause dysphonia or raspy voice.
ABSTRACT
Purpose: Inherited retinal dystrophies (IRD) are a heterogeneous group of retinal diseases leading to progressive loss of photoreceptors through apoptosis. Retinitis pigmentosa (RP) is considered the most common form of IRD. Panel?based testing in RP has proven effective in identifying the causative genetic mutations in 70% and 80% of the patients. This is a retrospective, observational, single?center study of 107 RP patients who had undergone next?generation sequencing?based targeted gene panel testing for IRD genes. These patients were inspected for common phenotypic features to arrive at meaningful genotype–phenotype correlation. Methods: Patients underwent complete ophthalmic examination, and blood was collected from the proband for DNA extraction after documenting the pedigree. Targeted Next Generation Sequencing (NGS) was done by panel?based testing for IRD genes followed by co?segregation analysis wherever applicable. Results: Of the 107 patients, 72 patients had pathogenic mutations. The mean age of onset of symptoms was 14 ± 12 years (range: 5–55). Mean (Best Corrected Visual Acuity) BCVA was 6/48 (0.9 logMAR) (range 0.0–3.0). At presentation, over one?third of eyes had BCVA worse than 6/60 (<1 logMAR). Phenotype analysis with the gene defects showed overlapping features, such as peripheral well?defined chorioretinal atrophic patches in patients with CERKL, PROM1, and RPE65 gene mutations and large macular lesions in patients with RDH12 and CRX gene mutations, respectively. Nummular or clump?like pigmentation was noted in CRB1, TTC8, PDE6A, and PDE6B. Conclusion: NGS?based genetic testing can help clinicians to diagnose RP more accurately, and phenotypic correlations can also help in better patient counselling with respect to prognosis and guidance regarding ongoing newer gene?based therapies.
ABSTRACT
Background: Mental health is important at every stage of life, from childhood and adolescence through adulthood. Worldwide interest in geriatric depression has increased but studies to assess the depression among the elderly population in urban slums has hardly been done. So this study would shed light on the risk factors of depression among geriatrics in urban slums. Aim & Objective: To study the epidemiological determinants such as age, marital status, education, financial dependency, economic status and chronic illness in relation to of depression among the geriatric population (60–80 years). Settings and Design: Community-based, cross-sectional study for 24 months with a samplesize of 209. Methods & Material: Urban slum area represented by one health post was selectedas the study area which caters to around 96,630 slum residents. Pre-tested semi-structuredinterviews were conducted after selecting households by systematic random sampling. Statistical analysis: Data was analyzed using SPSS version 21. A chi-square test was applied. Result: The present study shows overall prevalence of depression among the elderly above 60 years of age to be 48.6%. Depression is found to been significantly associated with an increase in age, living alone (72.7%), lower class economic status (100%), financial dependency (54%), history of chronic family illness (54.7%) and with no formal education (62.1%) among elderly dwelling in slums. Conclusions: There is a high prevalence of depression in the community and hence, a need to sensitize Primary level Health Care Services to institute screening tests considering the association of these determinants with depression and link them to specialized services for further management.
ABSTRACT
Purpose: To report the spectrum of posterior segment manifestations and visual outcomes in a large series of patients with systemic lupus erythematosus (SLE). Methods: Retrospective study at a tertiary referral eye center in south India between 2016 and 2022. Results: Charts of 109 patients diagnosed to have SLE were retrieved from our medical database. Only nine cases of SLE (8.25%) had posterior segment involvement. The male: female ratio was 1:8. The mean age was 28 years. Unilaterality was the most common presentation in eight cases (88.89%). Lupus nephritis was the most common systemic presentation in five cases (55.56%). Antiphospholipid antibodies (APLA) positivity was seen in two cases (22.22%). Ocular manifestations included microangiopathy (cotton wool spots) in one case, occlusive retinal vasculitis with cotton wool spots in four cases (five eyes), optic disc edema with combined venous and arterial occlusion (one case), central retinal vein occlusion with cotton wool spots and hemorrhages (one case), macular edema (four cases), posterior scleritis with optic disc edema and exudative retinal detachment in the posterior pole (one case), and tubercular choroidal granuloma (one case). Treatment included systemic steroids, hydroxychloroquine sulfate (HCQS), and immunosuppression in all cases, blood thinners in two cases, and laser photocoagulation in four cases. HCQS?related retinal toxicity was not seen in any of the 109 cases. Ocular manifestation was the initial presentation of SLE in one case. Visual outcome was poor in three cases. Conclusion: Presence of posterior segment findings in cases with SLE may suggest a severe systemic disease. Early detection and aggressive treatment result in better visual outcomes. Ophthalmologists could play a vital role in guiding systemic therapy.
ABSTRACT
Background & objectives: Oral squamous cell carcinoma (OSCC) is widely prevalent in the Indian subcontinent mainly due to habit-associated aetiologies. Immune regulation and angiogenesis are the part of tumourigenesis that play a crucial role in metastasis and survival. However, the concurrent expression of vascular endothelial growth factor (VEGF) and CD3 (immune regulator receptor on T-lymphocyte) in the same OSCC tissue samples has not been reported in the Indian population. The present study evaluated the expression of CD3+ T-cells and VEGF in OSCC tissue samples and studied the clinicopathological correlation and survival analysis in an Indian population. Methods: This was a retrospective study conducted on 30 formalin-fixed and paraffin embedded sections which were histologically diagnosed as OSCC cases comprising of 15 metastatic OSCC and 15 non- metastatic OSCC with available clinical data and survival status. Results: Reduced expression of CD3+ T-cells and increased VEGF expression were observed in metastatic OSCC samples. The correlation of expression of CD3+ T-cells and VEGF with clinicopathological parameters showed a significant association between these markers with age, nodal status, site of the lesion and survival. Interpretation & conclusions: Reduced expression of CD3+ T-cells in OSCC was found to be associated with a significantly poor survival. VEGF was found to be over expressed in metastatic OSCC as compared to that in non-metastatic OSCC. The study findings suggest that the evaluation of CD3 and VEGF in incisional OSCC biopsies can be considered for predicting the survival outcome and metastasis
ABSTRACT
Mental disorders in India form a major public health concern and the efforts to tackle these dates back to four decades, by way of the National Mental Health Programme (NMHP) and its operational arm, the District Mental Health Programme (DMHP). Although the progress of NMHP (and DMHP) was relatively slower till recently, the last 4-5 years have seen rapid strides with several initiatives, including (i) expansion of DMHPs to 90 per cent of the total districts of the country, (ii) the National Mental Health Policy and (iii) strengthening the Mental Health Legislation by way of providing explicit provisions for rights of persons with mental illnesses. Among others, factors responsible for this accelerated growth include the easily accessible digital technology as well as judicial activism. Federal and State cooperation is another notable feature of this expansion. In this review, the authors summarize the available information on the evolution of implementation and research aspects related to India’s NMHP over the years and provide a case for the positive turn of events witnessed in the recent years. However, the authors caution that these are still baby steps and much more remains to be done.
ABSTRACT
Autologous serum eye drops provide lubrication and promote epithelial healing. They have been successfully used in the management of ocular surface disorders such as dry eye disease, persistent epithelial defects and neurotrophic keratopathy for many decades. A great deal of variation in the methods of preparation of autologous serum eye drops, the end concentration and the duration of use exists in published literature. In this review, simplified recommendations for preparation, transport, storage and use of autologous serum are described. Evidence for the use of this modality in aqueous deficient dry eye disease is summarized, along with expertise-based rationale.
ABSTRACT
Evaporative dry eye (EDE) due to meibomian gland dysfunction (MGD) is one of the common clinical problems encountered in ophthalmology. It is a major cause of dry eye disease (DED) and of ocular morbidity. In EDE, inadequate quantity or quality of lipids produced by the meibomian glands leads to faster evaporation of the preocular tear film and symptoms and signs of DED. Although the diagnosis is made using a combination of clinical features and special diagnostic test results, the management of the disease might be challenging as it is often difficult to distinguish EDE from other subtypes of DED. This is critical because the approach to the treatment of DED is guided by identifying the underlying subtype and cause. The traditional treatment of MGD consists of warm compresses, lid massage, and improving lid hygiene, all measures aimed at relieving glandular obstruction and facilitating meibum outflow. In recent years, newer diagnostic imaging modalities and therapies for EDE like vectored thermal pulsation and intense pulsed light therapy have emerged. However, the multitude of management options may confuse the treating ophthalmologist, and a customized rather than a generalized approach is necessary for these patients. This review aims to provide a simplified approach to diagnose EDE due to MGD and to individualize treatment for each patient. The review also emphasizes the role of lifestyle modifications and appropriate counseling so that patients can have realistic expectations and enjoy a better quality of life.
ABSTRACT
Purpose: To understand the bacterial microbiome changes associated with Sjogren’s syndrome (SS) and non?Sjogren’s syndrome (NSS) aqueous?deficient dry eyes compared to healthy eyes. Methods: Bacterial microbiome was generated from the deoxyribonucleic acid of tear film samples in healthy (n = 33), SS (n = 17), and NSS (n = 28) individuals. Sequencing of the V3?V4 region of the 16S rRNA gene was performed on the Illumina HiSeq2500 platform. Quantitative Insights Into Microbial Ecology (QIIME) pipeline was used to assign taxa to sequences. Statistical analysis was performed in R to assess the alpha diversity and beta diversity indices. Significant changes between the healthy, SS, and NSS cohorts were depicted by principal coordinate analysis (PCoA), differential abundance, and network analysis. Results: Tear microbiome was generated in healthy, SS, and NSS samples. Phyla Actinobacteria, Firmicutes, and Bacteroidetes showed significant changes in SS and NSS compared to healthy. Genera Lactobacillus and Bacillus were predominantly present in all samples. PCoA and heat map analysis showed distinct clusters for SS and NSS from the healthy cohort. Genera Prevotella, Coriobacteriaceae UCG?003, Enterococcus, Streptomyces, Rhodobacter, Ezakiella, and Microbacterium significantly increased in abundance in SS and NSS compared to a healthy cohort. Bacteria–bacteria interaction in SS, NSS, and healthy cohorts was predicted by CoNet network analysis. This analysis predicted a major hub of interaction for the pro?inflammatory bacterium Prevotella in the SS and NSS cohorts. Conclusion: The results of the study indicate significant changes in the phyla and genera in SS and NSS compared to healthy. Both discriminative analysis and network analysis indicated a possible association of predominant pro?inflammatory bacteria with SS and NSS.
ABSTRACT
Purpose: An undergraduate research conducted during the pre?covid times, to highlight the importance of screen time and its association with dry eye in medical students. The aim was to study the prevalence of dry eye among medical students using the ocular surface index (OSDI) questionnaire. Methods: This was a cross?sectional study. This study was conducted among medical students using an OSDI questionnaire in the pre?covid times. Based on the pilot study, the minimum sample size calculated was 245. A total of 310 medical students participated in the study. These medical students answered the OSDI questionnaire. The OSDI score was used to categorize students with dry eye as mild (13–22 points), moderate (23–32 points), and severe (33–100 points). In addition, the associations between the OSDI score and possible risk factors such as gender, contact lens/spectacle wear, laptop/mobile usage, and duration of exposure to air conditioners were also studied. Results: The analysis of the study revealed that out of 310 students, dry eye was seen in 143 (46.1%) and severe dry eyes were seen in 50 (16.1%). A high OSDI score (>13 points) was associated with the usage of a laptop/mobile for more than 6 h in 40 (52.6%) (P < 0.001). Conclusion: The prevalence of dry eye among medical students was 46.1% in the present study. Longer duration of usage of visual display units (laptop/mobile) was the only factor that showed a statistically significant association with dry eye in our study.
ABSTRACT
Head-and-neck cancer is the fifth most frequently occurring cancer in India. Among the various treatment options, side effects such as trismus are mostly caused due to radiation therapy. Physical therapy is known to be beneficial in treating post-cancer treatment side effects. To the best of our knowledge, this is the first study report highlighting the efficacy of MaRhyThe© in treating radiation induced trismus. A multimodal approach (MaRhyThe©, Cupping therapy, Myofascial Release, and exercises) has shown to be beneficial in treating trismus, shoulder disability, pain, muscle spasm, and improving the quality of life in the head-and-neck cancer patient.
ABSTRACT
The present study assessed incidence, risk factors, in-hospital and short-term outcomes associated with no-reflow in patients undergoing percutaneous coronary intervention (PCI) in STEMI, NSTEMI, unstable angina and stable angina. Out of 449 patients, 42 (9.3%) developed no-reflow. Hypertension, dyslipidemia, obesity and smoking were significant risk factors. There was significant association of no-reflow with left main disease, multiple stents, target lesion length_x0001_ 20 mm and higher thrombus grade. Interestingly, 93 patients (23.4%) of normal flow had myocardial perfusion grade (MPG) of 0/1 with mortality in 9 (10%) patients. No-reflow is associated with poor in-hospital and short-term outcomes with higher incidence of death, cardiogenic shock, heart failure and MACE. Knowledge of risk factors of no-reflow portends a more meticulous approach to improve final outcomes. MPG could be better predictor of outcomes in these patients.
