Posttransplant lymphoproliferative disorder in renal transplant recipients: Experience from a Tertiary Care Center.

Posttransplant lymphoproliferative disorders (PTLDs) are potentially fatal complications arising after solid organ or hematopoietic stem cell transplant. The most crucial factor in pathogenesis of PTLDs is either a primary infection with Epstein-Barr virus or reactivation of its latent state due to immune dysregulation. This complex pathobiology leads to a myriad of clinical manifestations due to uncontrolled lymphoproliferation that may be reactive, polymorphous or monomorphous.

Plasma cell rich acute rejection: Risk factors, treatment and outcomes.

Plasma cell-rich rejection is a rare and poorly defined entity. Its treatment is not clearly defined and has universally poor prognosis. More data should be published from various transplant centers around the world to identify the treatment that has the best outcomes and to formulate treatment guidelines for these cases.

Monoclonal gammopathy of renal significance: Spectrum of diseases and approach to a case.

The occurrence of kidney diseases associated with a monoclonal gammopathy in the absence of symptomatic multiple myeloma is increasingly recognized. When the kidney is involved, the monoclonal etiology of these diseases results in clinical and laboratory features distinct from those of other disease, necessitating the nomenclature monoclonal gammopathy of renal significance (MGRS). The detection of these monoclonal diseases involving the kidney is important since they are poorly responsive to conventional immunosuppression and instead require clone-directed therapy.

Carotid artery web with fetal posterior cerebral artery variant masquerading as recurrent ipsilateral cryptogenic ischaemic strokes.

A 31-year-old woman was referred to vascular surgeons with the history of recurrent ischaemic strokes in two cerebral artery territories over a span of 1 year. On investigation, she was found to have a right internal carotid artery web, with thrombus and a fetal right posterior cerebral artery (PCA), which explained the ischaemic strokes in right middle cerebral and PCA territory. The rare association of these two infrequent entities makes the case a singular one in the medical literature.

Coomb's negative cold agglutinin disease: A rare report of an incidentally detected case.

Cold agglutinin disease (CAD) is a rare type of autoimmune hemolytic anemia which usually results due to production of immunoglobulin M-type autoantibody against the I/i and H antigens on red blood cell membrane. They can be idiopathic or may be due to underlying lymphoproliferative disorders or atypical infections. It can have a varied presentation ranging from being incidentally detected to being totally transfusion dependent for a longer or shorter duration.

The tale of TILs in breast cancer: A report from The International Immuno-Oncology Biomarker Working Group.

The advent of immune-checkpoint inhibitors (ICI) in modern oncology has significantly improved survival in several cancer settings. A subgroup of women with breast cancer (BC) has immunogenic infiltration of lymphocytes with expression of programmed death-ligand 1 (PD-L1). These patients may potentially benefit from ICI targeting the programmed death 1 (PD-1)/PD-L1 signaling axis.

Factors determining outcome of post-angiogram-negative subarachnoid hemorrhage.

Aim: To determine the risk factors affecting outcome at the end of 90 days of post-angiogram-negative subarachnoid hemorrhage (SAH).

Methods: Non-traumatic SAH cases were reviewed from the case records of patients who had reported to the Department of Neurology of a tertiary care hospital and 50 angio-negative SAH cases were included after excluding all the cases with known cause of hemorrhage after doing computed tomography angiography (CTA)/digital subtraction angiography (DSA). The presence of hypertension, diabetes mellitus, coronary artery disease (CAD), history of alcohol and smoking, and various scales like Hunt and Hess Scale (HHS), World Federation of Neurological Surgeons (WFNS), and Fisher scale had been recorded at admission.

Functional impairment in bronchiectasis: Spirometry parameters versus St. George's Respiratory Questionnaire scores: Any co-relation?

Objectives: Bronchiectasis is a common respiratory disease which has significant morbidity and mortality. Health-related quality of life scores are not routinely used for the assessment of bronchiectasis. The present study was undertaken with an aim to assess the clinical profile and functional impairment using spirometry in patients with bronchiectasis and to co-relate functional impairment with their St.

Favourable outcome in a child with acute lymphoblastic leukaemia and pulmonary mucormycosis managed with combination antifungal therapy of liposomal amphotericin B and caspofungin.

Pulmonary mucormycosis (PM) accounts for more than half the cases of mucormycosis in paediatric haematological malignancies, with mortality reaching as high as 90%. Surgical debridement of lesion along with liposomal amphotericin B (L-AMB) constitutes the mainstay of management of mucormycosis and offers best chances of survival. There are no reliable data available in the literature justifying the use of combination antifungal therapy (CAfT).

Hypereosinophilia: a rare cause of stroke and multiorgan dysfunction.

Eosinophilia can occur due to a plethora of allergic, infective, neoplastic and idiopathic conditions. Hypereosinophilic syndrome (HES) is characterised by sustained eosinophilia and multiorgan dysfunction in the absence of an identifiable cause. It may range from a self-limiting condition to a rapidly progressive life-threatening disorder, of which ischaemic stroke is a rare presentation.

Variation in Dosimeter Calibration Factor (N) Over a Period of 20 Years.

Long delays in renewal of calibration of secondary standards radiation dosimeters in radiation oncology centers due to the COVID19 pandemic have aroused concerns regarding accuracy in dose delivery to patients. The concerns are mainly due to the uncertainty in the absorbed dose to water calibration factor (N) over a period of time. In this study, the Nfactor for two ion chambers, thimble type (Farmer) and parallel plate type (Markus), used in most of the radiotherapy centers, were retrospectively reviewed for 20 years.

Hypomagnesemia with Secondary Hypoparathyroidism and Hypocalcemia due to Novel Variants in the Transient Receptor Potential Cation Channel Subfamily M Member 6 ( ) Gene.

HOMG1 (hypomagnesemia 1, intestinal) or hypomagnesemia with secondary hypocalcemia is a rare autosomal recessive disorder of magnesium metabolism, characterized by impaired magnesium absorption. This disorder may mimic other conditions presenting with neonatal seizures. Here, we report an infant diagnosed to have hypomagnesemia with secondary hypocalcemia due to novel variants in gene.

Coronary Artery Aneurysm After Drug-Eluting Stent Implantation Causing Coronary-Bronchial Fistula.

Coronary artery aneurysm (CAA) after drug-eluting stent implantation is rare, with a reported incidence of 0.3% to 6.0%.

Subglottic concretion masquerading as foreign body in a child with β thalassemia major: an airway nightmare!

Subglottic concretion is a rare and perilous condition usually presenting with existing or impending airway obstruction. Due to long-standing nature of the condition, slow progression of symptoms and rarity of occurrence, the condition is either missed or misdiagnosed. Its resemblance in presentation and symptoms to that of foreign body (FB) bronchus can lead to a diagnostic misadventure.

Innovative technique of mini-simple limbal epithelial transplantation in pediatric patients.

In this article, we introduce a modified technique of minor ipsilateral simple limbal epithelial transplantation (mini-SLET) in pediatric patients of limbal stem cell deficiency (LSCD). Two children with unilateral partial LSCD underwent the innovative technique of mini-SLET, where harvested limbal tissues were placed over the raw cornea and were covered with amniotic membrane. Both patients were followed till 9 months.

Comparison of a Voiding Diary With Clinical Management Tool As an Outpatient Screening Tool for Childhood Functional Voiding Disorders.

Objective: To study the agreement of questionnaire-based assessment with voiding diary for differentiating primary mono-symptomatic nocturnal enuresis from voiding disorder in children.

Method: Children 5-12 years old with bedwetting after exclusion of secondary enuresis were enrolled and parents filled a clinical management tool (CMT) questionnaire and a 48-hours voiding diary. Point prevalence and agreement of classification as primary mono-symptomatic nocturnal enuresis or voiding disorder were compared.

Scrub typhus and lateral rectus palsy: an uncommon presentation of a common illness.

Scrub typhus is a zoonosis, which usually manifests as an acute febrile illness. It is caused by a rickettsia, , which is endemic in the Asian region. It can present with varied clinical manifestations, ranging from acute febrile illness to life-threatening multiorgan dysfunction syndrome.
