RESUMO

Cryptococcal infection is a life-threatening, opportunistic infection in human immunodeficiency virus-infected individuals. The infection most commonly begins in the respiratory tract, with secondary involvement of the brain, skin, and lymph nodes. We report a rare case of isolated cervical cryptococcal lymphadenitis diagnosed on fine needle aspiration cytology, which was the initial presentation of secondary immunodeficiency in the patient. Periodic acid-Schiff stain, India ink preparation, and culture were done to confirm the diagnosis. He was diagnosed as HIV-positive on further investigation.

RESUMO

INTRODUCTION: The outbreak of coronavirus disease 2019 (Covid-19) severely impacted global health and economic status. The native receptor-ligand interaction of Angiotensin-converting enzyme 2 (ACE2) and S protein induces host cell pathogenesis via immunosuppression. MATERIAL AND METHODS: The emerging evidence reports the sex disparity in Covid-19 induced mortality rate which affects abundantly men population. Although the biological interaction of Covid-19 with receptor upregulates the viral genome protein interactions and initiates the predictive multiorgan failure followed by acute kidney injury (AKI) in Covid-19 infected male population. CONCLUSION: Besides, the knowledge and lessons learned from the study depict that cellular and molecular links may explain the risk and severity of Covid-19 and AKI in the male population and lead to management of Covid-19 induced AKI. Therefore, this review explored the pathways associated with the pathogenesis of two diseased conditions with sex disparity.

RESUMO

INTRODUCTION: Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is the sudden worsening of symptoms of COPD like shortness of breath, increased quantity and color of sputum, and systemic inflammation, and has a significant impact on survival. Biomarkers such as high-sensitivity C-reactive protein (hsCRP) and procalcitonin have been studied in AECOPD patients as prognostic markers. Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are two new inflammatory markers and play a significant role in prognosis in patients with AECOPD. NLR and PLR are easily available and cost-effective markers and have the potential for helping in the risk stratification of hospitalized AECOPD patients. AIM: Study of inflammatory markers in COPD and their correlation with clinical outcome. METHODS: A prospective observational comparative study was conducted on 100 patients of COPD at the Department of General Medicine, Vardhman Mahavir Medical College and Safdarjung Hospital, New Delhi, and all necessary investigations were done. RESULTS: A total of 100 patients of COPD were taken, 50 patients were in a stable state (controls) and the same number of patients were in an acute exacerbation state (cases). Mean levels of NLR, hsCRP, and procalcitonin in cases were significantly higher as compared to controls whereas levels of PLR in cases and controls were comparable with no significant difference between them. Levels of both of these inflammatory markers (NLR and PLR) were positively correlated with levels of hsCRP and levels of procalcitonin. Of the total 50 patients, 23 (56.00%) patients needed mechanical ventilation and 11 (22%) needed inotropic support. Only 6 out of 50 patients (12.00%) died. Levels of NLR and PLR were positively correlated with the duration of hospitalization. Levels of NLR and PLR were not significantly associated with the need of inotropic support and mortality, levels of NLR were also not significantly associated with the need of mechanical ventilation whereas levels of PLR were significantly higher in patients who required mechanical ventilation. CONCLUSION: Levels of NLR were raised in patients with AECOPD (cases) than stable state COPD patients (controls). So levels of NLR can be used as a marker to predict acute exacerbation and there was a positive correlation of NLR and PLR with levels of hsCRP and procalcitonin.

RESUMO

Metastatic neuroendocrine tumors to breast are very rare with less than 30 cases reported worldwide. The first case was reported in 1957 according to literature. Among these 13 cases reported as breast lump as initial presentation. As the tumor is not so common, the radiological features are not well defined leading to misdiagnosis. Bilateral breast metastasis from pancreatic neuroendocrine tumors has not been mentioned in the literature. Here, we present a case of pancreatic neuroendocrine tumor with metastasis to bilateral breast.

RESUMO

Entamoeba histolytica is an intestinal parasite causing significant morbidity and mortality in the developing world. More tools are needed to understand the epidemiology and molecular pathogenesis of amebiasis. Virulence pattern of E. histolytica could be linked with the genotype of a strain. Several loci showing insertion polymorphism of retrotransposable short interspersed nuclear elements EhSINE1 and EhSINE2 have been reported among laboratory strains of E. histolytica. The present study was undertaken to validate this observation in clinical isolates from north India. Our results indicate that the Indian samples show a different propensity of SINE retention or loss at two of the polymorphic loci compared with non-Indian samples. Statistical analysis of different loci revealed Locus 17 of EhSINE1as a potential geographical marker for distinguishing Indian isolates from non Indian isolates.

RESUMO

Pyrenochaeta romeroi is a rare fungal agent of chronic, suppurative subcutaneous infections leading to mycetoma. It is an unusual cause of deep, non-mycetomatous infections. We herein present review of the literature along with a case of 61-year-old Indian female with rheumatoid arthritis who developed subcutaneous phaeohyphomycosis caused by Pyrenochaeta romeroi. It posed a diagnostic challenge, as the culture from fine-needle aspirate revealed a non-sporulating dematiaceous mould, which was the only supportive tool for its diagnosis and initiation of the therapy. However, it was the molecular sequencing which played the pivotal role in clinching the final aetiological diagnosis. To the best of our knowledge, this is the 20th case of Pyrenochaeta species infection occurring worldwide and first case report of subcutaneous phaeohyphomycosis caused by Pyrenochaeta romeroi in a rheumatoid arthritis patient.

RESUMO

OBJECTIVE: To study alterations in and factors affecting blood levels of homocysteine and its related vitamins (B12 and folic acid) in patients with metabolic syndrome. Methods: In this case-control study, conducted in a referral hospital in north India, blood levels of vitamin B12, folic acid and homocysteine were compared and also correlated with anthropometric parameters, blood sugar, lipids (total, LDL and HDL cholesterol) and hematological variables. METHODS: Seventy five subjects (50 patients and 25 controls; mean age 48.6±11.5 years; 57% males) were studied. As compared to controls, patients with metabolic syndrome had higher blood levels of homocysteine (16.77±6.6 vs 6.48±0.87 units; P<0.0001), lower levels of B12 (183.7±37 vs 346.4±74.4 units; P<0.0001) and lower levels of folic acid (3.25±1.9 vs 5.31±0.75 units; P<0.0001). All 3 levels were abnormal in 64% patients and none of controls (P<0.0001). Blood levels of homocysteine, folic acid and vitamin B12 correlated with weight, waist circumference, body mass index, fasting blood sugar and lipid levels. These levels also correlated with hematological parameters (hemoglobin, mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration). CONCLUSIONS: Indian patients with metabolic syndrome have a strong association with elevated blood levels of homocysteine and reduced levels of vitamin B12 and folic acid. Further studies are needed to test the hypotheses that these metabolites have a greater role in Asians and there may be a greater beneficial role of folic acid supplementation.

RESUMO

Histoplasmosis is a progressive disease caused by dimorphic intracellular fungi and can prove fatal. Usually, it is present in immunocompromised individuals and immunocompetent individuals in the endemic zones. We report an unusual presentation of progressive disseminated histoplasmosis. The patient in the present case report was immunocompetent child and had fever, bone pains, gradual weight loss, lymphadenopathy and hepatosplenomegaly. Disseminated histoplasmosis (DH) was diagnosed on microscopic examination and fungal culture of bone marrow, blood, skin biopsy and lymph node aspirate. The patient died on seventh day of amphotericin B. In the absence of predisposing factors and classical clinical presentation of febrile neutropenia, lung, adrenal and oropharyngeal lesions, the disease posed a diagnostic challenge. Progressive disseminated histoplasmosis in children can be fatal despite timely diagnosis and therapy. In India, disseminated histoplasmosis is seen in immunocompetent hosts. All the pediatrics immunocompetent cases from India are also reviewed.

RESUMO

Metastasizing pleomorphic adenoma is recognized as a subtype of pleomorphic adenoma in WHO classification 5th edition of salivary glands. The controversy pertaining to the entity is the benign features of the disease even at a metastatic site. We present a rare case of left recurrent pre-auricular swelling in a young male reported as metastasizing pleomorphic adenoma. A nineteen-year-old male presented with left preauricular swelling seven years ago which was diagnosed as pleomorphic adenoma and underwent complete excision of tumour. The tumour recurred twice - two and five years after the surgery. At the second recurrence, the level II neck dissection showed multiple encapsulated deposits of pleomorphic adenoma having similar morphology in the cervical soft tissue with no features of high-grade transformation.

RESUMO

Background: Hemoglobin A1c (HbA1c) serves as a pivotal marker for long-term glycemic control. The Diabetes Control and Complications Trial (DCCT) established its relevance, yet gaps exist in understanding potential seasonal variations in HbA1c levels among diabetic patients. The study highlights the need to explore potential seasonal variations in HbA1c levels and their impact on diabetic patients. Materials and methods: This is an observational study conducted in a tertiary care hospital from January to December 2019, the study analyzed HbA1c levels in 8138 patients. Blood samples were collected using Potassium EDTA-containing vials and processed with an automated analyzer. Seasonal variations were explored using time series analysis. Results: Mean HbA1c levels peaked during the monsoon (June to September) and were lowest in autumn (October to November). Subgroup analysis revealed differences in patients with HbA1c values below and above 6.5 %. Those with controlled blood sugar showed higher levels in winter (December to February) and monsoon (June to September), while patients with HbA1c values ≥ 6.5 % exhibited significantly lower levels in monsoon (June to September) and autumn (October to November) compared to summer (March to May). Conclusion: In contrast to global trends, Indian patients demonstrated distinct seasonal variations in HbA1c levels. The highest levels during the monsoon (June to September) may be linked to reduced outdoor activity and dietary changes. The study emphasizes the need for tailored diabetes management considering seasonal influences. Further extensive, longitudinal studies across diverse Indian regions are recommended to comprehensively grasp the impact of seasonal changes on diabetes outcomes.

RESUMO

Introduction The ectopic pelvic kidneys have a higher likelihood of developing renal stones due to urinary stasis caused by the abnormal position of the renal pelvis, altered course of the ureter, and kidney malrotation. This retrospective study highlights the safety, efficacy, and feasibility of performing transperitoneal laparoscopic pyelolithotomy in cases of pelvic ectopic kidney. Methodology The 15 patients with ectopic pelvic kidneys and nephrolithiasis underwent laparoscopic pyelolithotomy. The kidney was exposed either by moving the bowel or using a trans-mesocolic approach. A surgical procedure was performed to remove stones from the renal pelvis using laparoscopic forceps. Following the placement of a double J stent, the incision in the renal pelvis was closed. The procedure was completed after the intraperitoneal drain was inserted. Results A total of 15 patients underwent the transperitoneal laparoscopic pyelolithotomy procedure, with a male-to-female ratio of 3:2. The average age of the patients was 41 (25-58) years, while the average size of the stones was 3.8 cm. Additionally, seven (46.6%) patients had the presence of caliceal stones in conjunction with the pelvic stone. Out of the 15 patients, some had stones on the left side (n = 9, 60%), while others had stones on the right side (n = 6, 40%). The operation with an average duration was 125 minutes with a range of (90-190). Fourteen (93.3%) patients were found to be free of stones. A patient required extracorporeal shock wave lithotripsy (ESWL) to address a small caliceal residual stone measuring 8 mm. After just one session of ESWL, this stone was completely cleared. All stones were successfully removed, resulting in a 100% stone-free rate. Conclusions Laparoscopic pyelolithotomy is a highly effective and efficient procedure for treating large and numerous stones in the ectopic pelvic kidney. This method has a significant level of efficiency in removing stones with limited consequences.

RESUMO

Objective: The most important determinant of patient outcome in cases of breast carcinoma is the regional lymph node status. Intraoperative assessment of sentinel lymph nodes (SLNs) allows the surgeon to perform axillary lymph node dissection in the same sitting if required. The commonly performed intraoperative methods for SLN evaluation are touch imprint cytology (TIC) and frozen section. The present study aimed to determine the sensitivity, specificity, and accuracy of TIC with histopathological diagnosis as gold standard. Material and Methods: The lymph nodes sent for intraoperative examination were bisected along the long axis and touched onto clean glass slides followed by Toluidine blue and rapid Papanicolaou staining. The imprints were reviewed and the interpretation was conveyed to the surgeon. Thereafter, the biopsy was fixed in 10% formalin followed by paraffin embedding with hematoxylin and eosin staining. The specificity, sensitivity, diagnostic accuracy, positive predictive value, and negative predictive value were evaluated with histopathological diagnosis as gold standard. Results: A total of 60 patients who underwent resection surgery were included in the study. Majority (36.7%) of patients were in the age group 41-50 years with a mean age of 48.1 ± 10.6 years. There were 54 cases (90%) and 6 cases (10%) of invasive carcinoma of no special type (ductal) and lobular carcinoma, respectively. According to modified Bloom-Richardson scoring, the cases were categorized as Grade 1-6 cases (10%), Grade 2-36 (60%), and Grade 3-18 (30%). The sensitivity and specificity of TIC were 87.5% and 100%, respectively. The diagnostic accuracy of TIC in the diagnosis of metastasis in SLN was 90%. Conclusion: TIC is an easy-to-perform, cost-effective, rapid, and accurate technique for axillary lymph node evaluation, which also overcomes the need for a cryostat.

RESUMO

Objective: In an era of minimally invasive and rapid diagnostic technologies, fine-needle aspiration cytology (FNAC) is most useful when it comes to patients with lymphadenopathies especially of the cervical region. Liquid-based cytology (LBC) is an alternative processing method which is used for both gynecological and non-gynecological samples. Because of the remarkable advantages of LBC smears in gynecological samples, nowadays, many studies have been done to assess its utility in various other lesions. Hereby, with the help of this study, we would like to evaluate the efficiency of LBC smears in comparison to conventional FNAC smears conventional smears (CS) on lymph node aspirates. Material and Methods: A retrospective study was done over a 1-year period in which 253 cases of lymph node aspirates were included in the study. The slides were prepared using standard conventional and LBC techniques and compared for adequacy, cellularity, cell architecture, necrosis, background debris, presence of cells in monolayer sheets, and nuclear/cytoplasmic details. Results: Of the total 253 cases, 171 (67.6%) were and 67 (26.5%) were diagnosed as non-neoplastic and malignant, respectively. Although the LBC smears were useful in the diagnosis of malignant cases, they did pose some challenges especially in the non-neoplastic lymph node aspirates due to loss of the background necrosis. In addition, the cellular yield in LBC smears was low in comparison to CS. Conclusion: LBC smears from lymph node aspirates results in better diagnostic accuracy for malignant cases due to better cellular and nuclear details. However, for non-neoplastic etiology, it should not be considered better than CS as loss of the background necrosis and inflammation may result in an incorrect diagnosis.

RESUMO

Introduction Bladder cancer is a significant health issue with an increased recurrence and progression rate, requiring invasive follow-up, which shows a poor prognosis. In addition, the prognostic role of mutant fibroblast growth factor receptor 3 (FGFR3) and tumor protein P53 (TP53) is controversial; therefore, we investigated the methylation status and their altered gene expression in low- and high-grade non-muscle-invasive bladder cancer (NMIBC) subjects. Materials and methods This case-control study was conducted between 2020 and 2023, in which n = 115 tumor tissues (NMIBC n = 85) and (controls n = 30) were examined for FGFR3 and FGFR promoter methylation and expression using methylation-specific PCR (MSP) and real-time PCR. The multivariate regression analysis and Kaplan-Meier (KM) plots were used to establish the association of FGFR3 and TP53 with clinicopathological features and survival outcomes of NMIBC patients. Results High-grade NMIBC tumors showed substantial methylation patterns, with TP53 hypomethylated (p = 0.034) and FGFR3 hypermethylated (p = 0.046), as well as significant mRNA expression of Tp53 and FGFR3 (p = 0.001). The multivariate analysis shows FGFR3 and Tp53 were associated with recurrence-free survival with sensitivity (p = 0.045 (78%); 0.034 (70.7%)) and progression-free survival (p = 0.022(61.5%); 0.038 (69.2%)).  Conclusion The findings of this investigation indicate that FGFR3 hypermethylation and TP53 hypomethylation are independent prognostic indicators that aid in the evaluation of disease outcomes in high-grade NMIBC tumors.

RESUMO

INTRODUCTION: Bladder cancer disproportionately affects men and often presents as nonmuscle-invasive bladder cancer (NMIBC). Despite initial treatments, the recurrence and progression of NMIBC are linked to autophagy. This study investigates the expression of autophagy genes (mTOR, ULK1, Beclin1, and LC3) in low and high-grade NMIBC, providing insights into potential prognostic markers and therapeutic targets. MATERIAL AND METHODS: A total of 115 tissue samples (n = 85 NMIBC (pTa, pT1, and CIS) and n = 30 control from BPH patients) were collected. The expression level of autophagy genes (mTOR, ULK1, Beclin1, and LC3) and their proteins were assessed in low and high-grade NMIBC, along with control tissue samples using quantitative real-time polymerase chain reaction and western blotting. Association with clinicopathological characteristics and autophagy gene expression was analyzed by multivariate and univariate survival analysis using SPSS. RESULT: In high-grade NMIBC, ULK1, P = 0.0150, Beclin1, P = 0.0041, and LC3, P = 0.0014, were substantially downregulated, whereas mTOR, P = 0.0006, was significantly upregulated. The KM plots show significant survival outcomes with autophagy genes. The clinicopathological characters, high grade (P = 0.019), tumor stage (CIS P = 0.039, pT1 P = 0.018, P = 0.045), male (P = 0.010), lymphovascular invasion (P = 0.028) and autophagy genes (ULK1 P = 0.002, beclin1 (P = 0.010, P = 0.022) were associated as risk factors for survival outcome in NMIBC patients. CONCLUSION: The upregulated mTOR, downregulated ULK1, and beclin1 expression is linked to a high-grade, CIS and pT1 stage, resulting in poor recurrence-free survival and progression-free survival and highlights the prognostic significance of autophagy gene in nonmuscle-invasive bladder cancer.

RESUMO

Background Intracapsular femoral neck fractures account for a majority of hip fractures. This study aimed to investigate the efficacy of valgus osteotomy as a primary treatment for intracapsular femoral neck fractures in adult patients aged 15-60 years, assessing its impact on functional outcomes and fracture union. Methodology A retrospective clinical analysis was conducted at the Department of Orthopedics and Traumatology, Osmania Government General Hospital, Hyderabad, India, focusing on patients treated with primary intertrochanteric valgus osteotomy for intracapsular femoral neck fractures. The study reviewed medical charts and radiographs of six patients aged between 15 and 60 years, diagnosed with recent isolated intracapsular femoral neck fractures, presenting between May 2019 and October 2021. The intervention involved Pauwels' intertrochanteric valgus osteotomy with various fixation methods. Main outcome measures included radiographic union, functional ability assessed by the Harris Hip Score, and evaluation for complications. Results All six patients achieved radiographic union at fracture and osteotomy sites, totaling a 100% success rate. The average follow-up duration was 14.8 months (12-20 months), with an average time of 5.1 months (2.5-6 months) from surgery to radiographic union. One patient experienced union with retroversion, while another developed avascular necrosis (AVN) by the study's conclusion. No instances of hardware failure or non-union were observed. The average Harris Hip Score obtained during the most recent clinical follow-up was 84, ranging from 69 to 94. All six patients regained independent walking ability without any support by the end of the follow-up period. Conclusion The combination of primary Pauwels' intertrochanteric valgus osteotomy with fixed-angle plating proves to be a highly effective method for addressing recent intracapsular femoral neck fractures, resulting in a 100% success rate in achieving union among the patient cohort.

RESUMO

Objective: Knowledge of proper collection, storage, preservation, and processing techniques is critical to ensuring proper handling and analysis of fluid cytology specimens. This study was conducted to determine the effect of anticoagulation, pre-smearing acetic acid treatment technique, and saline rehydration technique on morphological assessment, reproducibility, and reporting in fluid cytology. Material and Methods: The study was carried out in the cytopathology laboratory over 2 months (April-May 2022), where 100 effusion samples were analyzed. At least 20-40 mL of fluid was collected in heparinized and non-heparinized containers for each patient. Samples were processed in cytospin and stained with Giemsa and Papanicolaou stains. For 70 hemorrhagic specimens, an extra smear was prepared from the sediment and subjected to the saline rehydration technique as per the Indian Academy of Cytologists (IAC) guidelines. Seventy-three hemorrhagic specimens whose quantity received was more than 35 mL were subjected to the pre-smearing technique. These smears were evaluated for (a) the presence or absence of blue background/any other background staining, (b) cellularity, (c) cell morphology and (d) the presence/absence of microclots. Results: Heparinized samples showed no compromise in cellular morphology or cellularity although a blue background was observed in an occasional case. The pre-smearing technique had less background hemorrhage and preserved cell characteristics. The post-smearing saline rehydration technique did not compromise the cellularity but distorted morphology and showed background staining. Conclusion: The pre-smearing acetic acid treatment showed better-preserved cellularity and cytomorphology with the absence of background staining when compared to the post-smearing saline rehydration technique.

RESUMO

The interstitial lung diseases (ILDs) are a large, heterogeneous group of several hundred generally rare pulmonary pathologies, which show injury, inflammation and/or scarring in the lung. Although the aetiology of these disorders remains largely unknown, various cellular mechanisms have an important role in pathogenesis of fibrosis on the background of occupational, environmental and genetic factors. We have tried to provide new insights into the interactions and cellular contributions, analysing the roles of various cells in the pathogenesis of idiopathic pulmonary fibrosis.

RESUMO

Vulval fibroadenoma is an extremely rare lesion, mostly seen in young adults. A 51-years-old woman presented with a painless, mobile, and pedunculated vulval mass. Fine-needle aspiration (FNA) was performed and was diagnosed as a benign fibroepithelial lesion possibly fibroadenoma vulva, which was later confirmed as fibroadenoma vulva histopathologically. It is just not rare to find fibroadenoma vulva, but this should also be kept as a differential when diagnosing such cytomorphology in FNA lesions. This is important to avoid unnecessary incisional biopsy before excision.

RESUMO

INTRODUCTION: A retrospective study of 28 patients with obstetric combined vesicovaginal fistula (VVF) and rectovaginal fistula (RVF) treated at our centre throughout the last two decades (2002 to 2022) has been conducted. MATERIAL AND METHOD: In 12 patients, a preoperative diverting colostomy was performed. Six patients had single-stage surgery (both VVF and RVF repair in the same operation) of which two cases required transabdominal repair and four required transvaginal repair. RESULT: All single-stage repairs (n=6) were successful in curing urine and faecal incontinence. In 22 patients, VVF was corrected initially via the transvaginal method with Martius flap interposition, followed by RVF repair three months later. In 2/22 patients, there was a leak after RVF repair; therefore, proximal diverting colostomy was performed, and RVF repair was repeated after six months. CONCLUSION: All cases had effective VVF and RVF repairs, and both urine and faecal incontinence were completely cured. This study suggests the collaborative engagement of a urologist and a surgical gastroenterologist results in an advantageous outcome for the surgical treatment of these intricate obstetric fistulas.
