Association between malaria parasite density and hematological profile in malaria infected children at a Nigerian Private hospital
Authors: Adetunji Oyedeji Olusola 
Published: January 2024

Background & objectives:
The correct association between Plasmodium falciparum parasite density and the cellular constituents of blood is not known in entirety in Nigerian children. Thus, we decided to study the association between cellular blood constituents and malaria parasite density in malaria infected children attending a Nigerian hospital.

Methods:
A study of all children diagnosed with malaria fever at the Pediatric out-patient clinic, Cedar Crest Hospital, Abuja, Nigeria, was conducted. Packed cell volume, white blood cells with differentials and platelet counts and malaria parasite densities obtained from blood samples were studied. Malaria parasite densities more than 2 pluses were classified as significant parasitemia and 1 plus as non-significant. Information obtained was recorded and analysed with SPSS 22 software.

Results:
A total 143 children (74 boys and 69 girls) diagnosed with malaria of ages between 5 months to 17 years (mean 5.24 ±4.60) were studied. The majority of 141 (98.6%) had non-significant P. falciparum parasitemia, while 2 (2.4%) had significant parasitemia. Of the 143 children with malaria, 116 (81.1%) had a normal leucocyte count. All children with significant parasitemia had a normal leucocyte count. Of the 143 children, 11 (7.7%) had anemia and 10 (7.0%) thrombocytopenia. Anemia, monocytosis and thrombocytopenia were significantly associated with significant malaria parasitemia (p<0.05). Mean platelet counts was significantly less amongst those with significant parasitemia (p<0.01).

Interpretation & conclusion:
All patients with significant malaria parasitemia had normal leucocyte count. Significant malaria parasitemia is significantly associated with anemia, thrombocytopenia and monocytosis. Blood film appearances showing these changes are suggestive of significant malaria parasitemia.

Authors: Jena Sasmita Rani , Kaliyamoorthy M , Bhattacharyya T K , Baruah Kalpana 
Published: January 2024

ABSTRACT

Background & objectives:
In Port Blair, the capital of Andaman & Nicobar Islands, in the Bay of Bengal, there was a sudden increase in fever cases resembling the symptoms of dengue in the monsoon period of 2022. Hence, an investigation was carried out to find out both epidemiological and entomological reasons behind the outbreak.

Methods:
An Entomological survey was carried out in 24 wards of Port Blair Municipal Council (PBMC) area, epidemiological data of last six years (January to December of 2017–2021 & January to October of 2022) and patient details of the year 2022 were collected. Both the epidemiological and entomological data were analyzed concerning time and place.

Results:
During this outbreak period tyres (22.4%) came out as a major breeding habitat followed by small discarded materials (17.5%), metal drums (15.3%), and plastic drums (11.7%). In rainy season peri-domestic breeding (55%) was more than the domestic breeding (45%) habitat. Ae. aegypti had a high preference for indoor large containers (100-1000 L) like plastic tank, metal drum and cement tank whereas Ae. albopictus prefers to breed in medium sized plastic container (20-100 L) and outdoor water receptacles like tyres, flower pots, domestic discarded materials etc.

Interpretation & conclusion:
By source reduction, indoor space spray and outdoor fogging vector density was controlled which curtailed the transmission and within 8 weeks decreasing trend of dengue cases were noticed. A regular entomological survey is very important to know the seasonality and key breeding habitats of the vector for proper planning of vector control.

Authors: Wiwanitmkit Somsri , Wiwanitkit Viroj 
Published: January 2024

ABSTRACT

Background & objectives:
The goal of this study was to see how well an AI language model called Chat Generative Pre-trained Transformer (ChatGPT) assisted healthcare personnel in selecting relevant medications for filariasis therapy. A team of medical specialists and tropical medicine experts reviewed ChatGPT's recommendations for ten hypothetical filariasis clinical situations.

Methods:
The purpose of this study was to look at the effectiveness of an AI language model called Chat Generative Pre-trained Transformer (ChatGPT) in supporting healthcare providers in picking appropriate drugs for filariasis treatment. Ten hypothetical filariasis clinical cases were submitted to ChatGPT, and its recommendations were evaluated by a panel of medical professionals and tropical medicine experts.

Results:
ChatGPT gave appropriate suggestions for potential medication repurposing in filariasis treatment in all ten clinical scenarios. Its drug recommendations were in line with current medical research and literature. Despite the lack of particular treatment regimens, ChatGPT's general ideas proved useful for healthcare practitioners, providing insights and updates on prospective drug repurposing tactics.

Interpretation & conclusion:
ChatGPT shows promise as a useful method for repurposing drugs in the treatment of filariasis. Its thorough and brief responses make it useful for finding possible pharmacological candidates. However, it is critical to recognize ChatGPT's limitations, such as the requirement for additional clinical information and the inability to change therapy. Further research and development are required to optimize its use in filariasis therapy settings.
Unveiling Malaria's Silent Threat: From Socioeconomic Divides to Religious Influences, A Path to Effective Prevention in India
Authors: Aiman Ume , Azad Zainab , Awais Abdul Raffay 
Published: January 2024

ABSTRACT
Malaria remains a formidable public health challenge in India, particularly in low-socioeconomic regions, where it exacts a heavy toll on lives every year. This pressing issue gains prominence in light of a recent study conducted by Ronald et al. in Uganda, which illuminates the factors contributing to the elevated prevalence of malaria in economically disadvantaged areas. The study underscores the efficacy of interventions such as insecticide-treated nets (ITNs) and indoor residual spraying (IRS) in curtailing malaria incidence. Additionally, the World Health Organization's endorsement of the RTS, S/AS01 (RTS, S) malaria vaccine presents a promising development in the battle against this devastating disease. This letter underscores the imperative nature of implementing comprehensive strategies in India, which encompass widespread ITN distribution, the expansion of IRS programs, and the integration of the RTS, S/AS01 vaccine into the national immunization regimen. These concerted efforts are pivotal in furnishing cost-effective preventive measures to counter the mounting wave of malaria cases in India. Confronting malaria through a multifaceted approach stands as an essential approach to mitigate the disease's burden and ultimately safeguard the lives of India's vulnerable populations.
In silico screening of potential plant peptides against the Non-structural proteins of Dengue virus
Authors: Reena G , Ranjani R , Gowtham D , Sangeetha K 
Published: January 2024

ABSTRACT

Background & objectives:
Peptides isolated from different sources of plants have the advantages of specificity, lower toxicity, and increased therapeutic effects; hence, it is necessary to search for newer antivirals from plant sources for the treatment of dengue viral infections.

Methods:

In silico screening of selected plant peptides against the non-structural protein 1, NS3 protease domain (NS2B-NS3Pro) with the cofactor and ATPase/Helicase domain (NS3 helicase domain/NS3hel) of Dengue virus was performed. The physicochemical characteristics of the peptides were calculated using Protparam tools, and the allergenicity and toxicity profiles were assessed using allergenFP and ToxinPred, respectively.

Results:
Among the tested compounds, Ginkbilobin demonstrated higher binding energy against three tested non-structural protein targets. Kalata β-8 demonstrated maximum binding energy against NSP-1 and NSP-2, whereas Circulin A acted against the NSP3 protein of the dengue virus.

Interpretation & conclusion:
Hence, the three compounds identified by in silico screening can be tested further for in vitro studies, which could act as potential leads as they are involved in hampering the replication of the dengue virus by interacting with the three prime non-structural proteins.
Sarcomatoid variant of Xp11 translocation renal cell carcinoma: A rare case report in an adult female
Authors: Jagdale Rakhi V. , Jain Supriya , Pol Jaydeep N. , Khochikar Makarand V. 
Published: January 2024

ABSTRACT
Xp11 translocation renal cell carcinoma (XPTRCC) is a very rare kidney neoplasm, which has been predominantly reported in young patients. Sarcomatoid transformation in renal cell carcinomas is known. However, its occurrence in XPTRCC is unreported so far in the literature. We report a unique case of sarcomatoid transformation in a XPTRCC in a 23-year-old female, who presented with a huge right-sided renal mass and had metastatic deposits in lungs. Morphologically, clear cell morphology with papillary architecture along with foci of sarcomatoid transformation and rhabdoid differentiation were noted. Immunohistochemistry showed Pax-8 and TFE-3 expression in all components including the sarcomatous areas, whereas CK and EMA were expressed in conventional clear cell component. We present an extremely rare case of sarcomatous transformation in XPTRCC and discuss the case as determined by histopathology and immunocytochemistry. To our knowledge, this is the first case of sarcomatoid transformation XPTRCC being reported in the world literature.
An unreported case of intraoperative frozen section diagnosis of a sclerosing stromal tumor of the ovary- A report with a review

Published: January 2024

ABSTRACT
Sclerosing stromal tumor is a benign sex cord-stromal tumor, that commonly occurs in the second and third decades of age. Intraoperative diagnosis of this entity poses a great challenge because of the rare occurrence and can mimic malignant lesions. A 15-year-old female presented with a right ovarian mass. Serum markers were within normal limits. The radiological evaluation showed a large heterogeneously enhancing solid cystic abdominopelvic mass of size 16 × 14 × 9 cm with non-visualization of both ovaries separately and a few areas of calcification with mild ascites. An open cystectomy was performed. A part of the cyst wall was sent for an intraoperative frozen section. It was reported as sclerosing stromal tumor, and the post-operative specimen also confirmed the same. Areas of calcification and ossification were also identified as additional findings. We reported this case because of the uncommon occurrence, highlighting additional histological features, and also did a literature review, especially focussing on the intra-operative diagnosis.
Hemophagocytic lymphohistiocytosis following enteric fever: A rare autopsy case report
Authors: Fernandes Gwendolyn , Mhashete Pooja , Patwardhan Pranav Pramod 
Published: January 2024

ABSTRACT
Hemophagocytic lymphohistiocytosis (HLH) is a severe and frequently underdiagnosed disorder of systemic immune dysregulation resulting in hypercytokinemia and histologically evident hemophagocytosis, We report a case of a 34-year-old man who presented with breathlessness, generalized weakness, and fever of unknown origin with pancytopenia. Clinically the patient was admitted for febrile illness, and treated symptomatically but his general condition worsened leading to death within 21 hours of admission. A complete autopsy was performed. The deceased had a significant past history of repeated episodes of fever, weight loss, and axillary lymphadenopathy over a period of 8 months with multiple hospital admissions. He was also diagnosed with enteric fever (Widal test and Typhi IgM positive) at the start of these episodes. Hemogram during this period revealed persistent pancytopenia. Serum ferritin, serum triglycerides, and liver function tests were consistently deranged. Investigations for the etiology of fever and blood cultures were negative while the bone marrow aspirate revealed a normocellular marrow. CT abdomen-pelvis showed mild hepatomegaly with enlarged retroperitoneal lymph nodes. Infective endocarditis, lymphoma, and bronchopneumonia were being considered the clinical diagnoses. The significant autopsy findings were hepatosplenomegaly with retroperitoneal lymphadenopathy and multiple gastric ulcers. On microscopy, the liver, spleen, bone marrow, and lymph nodes showed characteristic hemophagocytosis. Post-mortem histopathological examination clinched the diagnosis of HLH and fulfilled six out of eight diagnostic criteria of the HLH-2004 protocol. We discuss the clinical course and diagnosis of this unique case and strive to create awareness about secondary HLH induced by common diseases, such as enteric fever.
Ossifying fibromyxoid tumor: A rare case report with review of literature and its differential diagnosis
Authors: Dhandapani Karthik , Gandhi Jahnavi , Gami Amisha 
Published: January 2024

ABSTRACT
Ossifying fibromyxoid tumor (OFMT) is a rare mesenchymal tumor of uncertain histogenesis with intermediate malignant potential presenting commonly in the fifth to sixth decade in the proximal limb and limb girdle. A 65-year-old male patient presented with a slow-growing gluteal mass. Wide local excision performed showed a well-defined tumor in the subcutaneous plane with a partially hard outer shell. Microscopy showed a moderately cellular tumor having cords and nests of round to ovoid cells with moderate cytoplasm and bland nuclei embedded in a myxo-hyaline matrix. An incomplete peripheral rim of ossification was seen. Pleomorphism/high cellularity was not seen. Mitosis was <2/50 high-power field. On immunohistochemistry, both S100 and desmin were positive. A diagnosis of typical OFMT was rendered. Even though rare with many morphological mimics, OFMT should be diagnosed with precision as most of these tumors are low-grade tumors that require only wide local excision and close follow-up without any adjuvant therapy.

Authors: Han Yongliang , Wei Shufei , Zhang Yihang , Wang Liangliang , Xu Xiao 
Published: January 2024

ABSTRACT
Extranodal nasal-type natural killer (NK)/T-cell lymphoma is a type of non-Hodgkin lymphoma. Neoplastic lymphocytes are positive for CD4, CD56, and CD20, a specific B-cell marker. CD20 positive NK/T-cell lymphoma is rare, with only nine reported cases. This paper reports a case of nasal-type NK/T-cell lymphoma with CD20 positivity in a 47-year-old woman. The patient presented with bilateral nasal congestion and bloody nasal cavity secretions for 2 months. Computed tomography revealed thickening of the nasal mucosa and posterior wall of the nasopharyngeal crest, and the left and right cervical lymph nodes were enlarged. On histopathology, the lesion was composed of medium-sized atypical lymphoid cells and vascular infringement. Immunohistochemical staining showed that the tumor cells were positive for CD20, CD3, CD56, and Epstein–Barr virus (EBV)-encoded RNA in situ hybridization. The patient was treated with radiotherapy for 2 months and is currently well.
MiT family translocation-associated renal cell carcinoma: A report of two cases in children
Authors: Mukherjee Sriranjan , Basu Keya , Basu Kalyani S. , Chatterjee Uttara 
Published: January 2024

ABSTRACT
Renal cell carcinoma is uncommon in children and must be distinguished from the more common Wilms’ tumor. Here, we present two cases of renal cell carcinoma in children both of whom presented with hematuria. Accurate diagnosis is essential in order to differentiate it from epithelial predominant Wilms’ tumor which has vastly different prognosis and treatment. Immunohistochemistry for TFE3 is useful in establishing the diagnosis.
Peripheral blood smear – An expeditious test in the preliminary diagnosis of bone marrow embolism in a case of multiple fractures: A case report
Authors: Rajashekar Rajalakshmi B. , Suchitha S , Shetty Mahesh S , Gowda Apoorva P. 
Published: January 2024

ABSTRACT
Bone marrow embolism is known to occur after fractures of long bones such as the femur and pelvis. We report a case of multiple fractures in a 32-year-old female patient, demonstrating bone marrow elements in the peripheral blood as early as 2 hours after trauma. This is the first case being reported with an ante-mortem demonstration of circulating marrow emboli in the peripheral blood, while the previously reported cases have demonstrated the emboli in post-mortem examination. A careful correlation of the clinical history of trauma, hematology auto-analyzer results, and the presence of bone marrow particles and fat globules in peripheral blood helped in arriving at the diagnosis of fat embolism in our case irrefutably.

Published: January 2024

ABSTRACTObjective:To study the spectrum and distribution of histopathological changes and evaluate immunohistochemistry markers p53 protein and Ki67 antigen in various lesions of gall bladder.Materials and Methods:A total of 804 consecutive gall bladder specimens were evaluated. Forty cases were selected for immunohistochemical analysis to evaluate expression of p53 and ki67 proliferation index, including 20 carcinoma gall bladder cases and 20 cases of inflammatory pathology associated with metaplasia, atypia, hyperplasia, dysplasia, and adenoma. p53 immunostaining was categorized as wild type and mutant type. ki67 of >20% was considered high expression.Results:The majority of the gall bladder lesions were inflammatory in origin, most common being chronic cholecystitis. In the group of 20 gall bladder carcinoma cases, 65% were p53 mutant and the remaining 35% cases had a p53 wild-type immunophenotype. 55% cases showed high expression for ki67 labeling. However, significant correlation (P< 0.05) was seen with lympho-vascular invasion. Among non-malignant lesions, normal/wild-type p53 expression was seen with increasing intensity and positivity in lesions with atypia and intra-epithelial neoplasms. Ki67 index also showed the same trend in all cases.Conclusions:p53 and ki-67 expression increases in inflammation, and further increment occurs in premalignant and malignant lesions of the gall bladder epithelium and can be used as a marker of aggression of histopathological lesions. The results emphasize the potential of Ki-67 and p53 as biomarkers of carcinogenesis in gall bladder carcinoma.
Shaggy aorta—An autopsy analysis
Authors: Zare Pranita , Vaideeswar Pradeep 
Published: January 2024

ABSTRACT

Aims:
Shaggy aorta is defined as “very extensive atheromatous disease with diffuse ulcers associated with soft, loosely held debris and a paucity of actual thrombus” and often results in visceral or peripheral arterial embolization (shaggy aorta syndrome). Most of the studies are clinico-radiological with hardly any assessment of the pathological features. We present an autopsy analysis of shaggy aorta.

Materials and Methods:
A retrospective study of autopsied cases of shaggy aorta over 15 years was conducted. The involvement of the various segments of the aorta (ascending, transverse, thoracic, and abdominal) was correlated with the clinical manifestations and cardiac/extra-cardiac findings at autopsy. The mortality was categorized as those related to shaggy aorta (Group I), related to cardiac diseases (Group II), and those unrelated to cardiovascular diseases (Group III).

Statistical Analysis:
Nil.

Results:
In a span of 15 years, there were 76 cases of shaggy aorta affecting predominantly males (85.5%) and patients in the sixth decades of life (mean age of 64.5 years). The important associated cardiovascular risk factors included hypertension, tobacco use, and diabetes mellitus. Predominant involvement of the entire aorta and arch + descending aorta was seen in 39.5% and 35.5% of the cases, respectively. Regardless of extreme severity, only half of the patients (37 cases, 48. 7%) had clinical presentation due to shaggy aorta.

Conclusions:
The occurrence of shaggy aorta may be more common than expected, and it would be important to keep this possibility in mind even in asymptomatic elderly patients with cardiovascular risk factors since aorto-arterial manipulations and anti-coagulant therapy can prove detrimental in such patients.

Published: January 2024

ABSTRACT

Background:
The incidence of meningoencephalitis (ME) in India is poorly understood, and the exact etiological diagnosis is often not possible. This study was planned to elucidate the bacterial and viral etiological diagnosis of ME in children less than 5 years of age.

Materials and Methods:
The present study was conducted in Virus Research and Diagnostic Laboratory (VRDL), Department of Microbiology, King George’s Medical University, Lucknow, from July 2020 to June 2022. Serum, cerebrospinal fluid (CSF), and nose/throat swabs were collected from all the enrolled cases of meningoencephalitis in children below 5 years of age and tested for various etiological agents by ELISA and/or real-time PCR.

Results:
Of 130 enrolled cases, 50 (38.5%) cases tested positive for one or more etiological agents. Etiological agents of ME detected were Japanese encephalitis virus (JEV) (8.46%), adenovirus (6.92%), influenza virus (5.38%), dengue virus (3.85%), Parvo B-19 virus (3.08%), Orientia tsutsugamushi (3.08%), Herpes Simplex Virus-1 (HSV-1) (1.54%), measles virus (1.54%), and Varicella-Zoster Virus (VZV) (1.54%). Rubella virus, Chikungunya virus (CHKV), Mumps virus, Enteroviruses, Parecho virus, John Cunningham virus (JC), BK virus, Nipah virus, Kyasanur Forest Disease virus (KFD), Chandipura virus, Herpes Simplex Virus (HSV-2), SARS CoV-2, N. Meningitides, and H. Influenzae were tested but not detected in any of the cases.

Conclusion:
We identified the etiological agents in 50/130 (38.5%) suspected ME cases in children less than 5 years of age, using molecular and ELISA-based diagnostic methods. The four most common pathogens detected were JEV, adenovirus, influenza virus, and dengue virus.
Primary neurolymphomatosis presenting as foot drop: A rare case report
Authors: Bakshi Neha , Chand Vineeta , Anand Rajiv , Duggal Rajan 
Published: January 2024

ABSTRACT
Neurolymphomatosis (NL) is the direct infiltration of the peripheral nervous system (PNS) by lymphoma cells and represents the least common form of PNS involvement by lymphoma. Clinical presentation is varied, and early diagnosis remains challenging. Nerve biopsy remains the diagnostic gold standard, use of magnetic resonance imaging (MRI) and fluorodeoxyglucose–positron emission tomography (FDG-PET) may help in diagnosis and selecting targets for biopsy. We report an account of an older male patient who presented with subacute onset multifocal neuropathy involving bilateral lower limbs and left foot drop. The patient was initially misdiagnosed as chronic inflammatory demyelinating polyneuropathy; however radiological assessment revealed fusiform thickening of the L5 nerve root and biopsy from the site revealed extensive infiltration by diffuse large B cell type non-Hodgkin lymphoma (NHL). High index of suspicion is vital to ensure correct diagnosis, timely treatment, and to improve patient survival.
