ABSTRACT
Aspergillus infection is relatively rare disease, and we present a case of orbital aspergillus infection who presented with right orbital pain and swelling. Right orbital lesion was identified on CT, MRI, and PET-CT imaging followed by confirmation of aspergillus on histopathological examination. We demonstrate that Tc-99 m ubiquicidin scan can yield positive results in aspergillosis too, enabling its differentiation from non-infective pathologies.

The main aims of the study were to study the Radiological findings of Temporal Bone in Atticoantral type of chronic suppurative otitits media; and to correlate the findings of HRCT temporal bone showing Atticoantral type of chronic suppurative otitits media; with intra-operative findings in Tympanomastoid surgeries
ABSTRACT
Background: There is limited data from India regarding medical management of congenital hyperinsulinism (CHI). Objective: To study the molecular diagnosis, medical management and outcomes of children with CHI. Study design: Ambispective. Participants: Children with CHI admitted in from December, 2011 till March, 2020 at a tertiary care referral hospital. Outcomes: Clinical and genetic profile, treatment, and response Results: 42 children with a median age of 3 days (range 1 day to 6 years) were enrolled, of which 23 (54.7%) were diazoxideresponsive. Mutations were identified in 28 out of 41 (68.2%) patients. The commonest gene affected was ABCC8 in 22 patients. The pathogenic variant c.331G>A in ABCC8 gene was identified in 6 unrelated cases from one community. Good response to daily octreotide was seen in 13 of the 19 (68.4%) diazoxide-unresponsive patients. Monthly long-acting octreotide was initiated and daily octreotide could be stopped or tapered in 9 patients. Sirolimus was tried with variable response in 6 patients but was discontinued in 5 due to adverse effects. Four patients had focal CHI, of which one underwent partial pancreatic resection. The disease severity reduced with age and neurodevelopment was good in the patients with identifiable genetic defects who were optimally managed. Conclusions: Medical management of CHI is effective, if compliance can be ensured, with good quality of life and neurological outcomes.
ABSTRACT
@#A 35-year-old female presented with abdominal pain, fever, projectile vomiting, and a diffuse tender epigastric mass. She was diagnosed to have acute persistent pancreatitis with a pancreatic pseudocyst. Elevated serum calcium levels provided an etiologic link between hypercalcemia and pancreatitis. On examination, a nodule was found in the left side of her neck which was later diagnosed as a giant left inferior parathyroid adenoma. This report highlights the critical analysis of history, examination, and investigations to reach an ultimate diagnosis. Pseudocyst drainage and parathyroidectomy resolved her symptoms.

Purpose@#Neuroblastoma (NB) is childhood’s most common extracranial solid malignancy. We have compared two imaging modalities, 131I-MIBG and 18F-DOPA PET/CT, to evaluate NB. Also, feasibility of the application of standardised scoring systems, SIOPEN and Curie scoring systems, in 18F-DOPA PET/CT was explored. @*Methods@#Patients with histopathology-proven NB underwent 131I-MIBG (planar and SPECT/CT) and 18F-DOPA PET/CT scans, as per standard imaging protocols. Duration between scans ranged from 1 to 30 days (median = 8 days). Number of lesions in Curie and SIOPEN scoring systems applied on both modalities was compared. @*Results@#Forty-six patients were included (M:F = 29:17) with a median age of 36 months. Both 131I-MIBG and 18F-DOPA scans were positive in 39 patients and negative in four patients. 18F-DOPA PET/CT was positive in additional three patients, in which 131I-MIBG was negative (p = 0.25). Overall, 18F-DOPA identified significantly greater number of lesions than 131I-MIBG, especially metastatic skeletal lesions (p 0.05). CS and SIOPEN scores were significantly higher in bone marrow-positive patients. @*Conclusion@#18F-DOPA PET/CT detected more lesions than 131I-MIBG but had little impact on staging of the disease. For evaluation of NB, both scans can be used interchangeably as per the availability. Furthermore, both SIOPEN and Curie scoring systems, standardised for MIBG, can also be used to semi-quantify disease extent in 18F-DOPA PET/CT.
ABSTRACT
Although prostate cancer can metastasize to any part of the body, laryngeal cartilage metastasis is extremely rare and few cases have been published so far. Here we present the case of a 65-year-old male patient, recently diagnosed with prostate adenocarcinoma, referred for staging with 68Ga-PSMA PET/CT. He was found to have extensive skeletal metastasis along with cartilage metastasis involving both thyroid and cricoid cartilages.
ABSTRACT
PURPOSE@#The effective half-life of radioiodine is an important parameter for dosimetry in differentiated thyroid cancer patients, particularly in children. We determined the pre-therapy and post-therapy effective half-life in different types of lesions, i.e., remnant, node, or lung metastases.@*METHODS@#Of 84 patients recruited, 27 were < 18 years (group 1) and the remaining 57 were between 18 and 21 years (group 2). A total of 114 studies were conducted and 253 lesions were analyzed. Serial whole-body scans were acquired at 24, 48, and ≥ 72 h after administration of iodine-131. Region of interests was drawn over lesions to determine counts in the lesion. Time versus counts graphs were plotted and mono-exponentially fitted to determine effective half-life.@*RESULTS@#The post-therapy effective half-life was found to be lesser than pre-therapy effective half-life in all types of lesions and in all groups. Median effective half-life was found maximum in intact lobe, minimum in the lung, and intermediate in remnant and nodes. In the assessment of all lesions together, pre- and post-therapy median and interquartile range (IQR) effective half-life were 59.8 (37–112) h and 48.6 (35.2–70.8) h (p < 0.0001) in group 1, 73.9 (46.2–112.7) h and 60 (57.4–85.9) h (p < 0.0001) in group 2, and 68.6 (41.53–112.36) h and 54.7 (36–80.6) h (p < 0.0001) in combined group, respectively. Importantly, the pre- and post-therapy median effective half-life serially dropped after each successive cycles of iodine-131.@*CONCLUSIONS@#There was a significant difference in pre-therapy and post-therapy effective half-life in all types of lesions. These results may have implications in calculating the correct therapeutic dose in children and in young adults.
ABSTRACT
Immunoglobulin G4 (IgG4)–related diseases are a spectrum of systemic inflammatory conditions of unknown etiology, which are characterized by infiltration of tissues by IgG4 plasma cells and sclerosing inflammation (Cheuk and Chan Adv Anat Pathol 17:303-32, 2010). Although this condition was initially described in relation to autoimmune pancreatitis, now it has been reported in almost every organ system of body (Zen and Nakanuma Am J Surg Pathol 34:1812-9, 2010, Masaki et al. Ann Rheuma Dis 68:1310-5, 2009). Orbital involvement by IgG4 disease can involve extraocular muscles (EOM), lacrimal glands, conjunctiva, eyelids, infraorbital nerve, orbital fat, and nasolacrimal system (McNab and McKelvie. Ophthal Plast Reconstr Surg 31:167-78, 2015, Katsura et al. Neuroradiology 54:873-82, 2012). The basis of using â¶â¸Ga-DOTANOC PET/CT in IgG4 orbital disease is the known expression of somatostatin receptors in chronic inflammatory cells (Cuccurullo et al. Indian J Radiol Imaging 27:509-16, 2017) and also avidity shown previously in other IgG4-related diseases (Cheng et al. Clin Nucl Med 43:773-6, 2018).
ABSTRACT
¹â¸F-DOPA PET/CT is commonly done in patients with persistent hyperinsulinemic hypoglycemia of infancy (PHHI) to look for any focal lesion in the pancreas.We present the findings in a 20-day-old neonate with PHHI who underwent ¹â¸F-DOPA PET/CT. The scan showed diffuse uptake in the pancreas with no focal lesion, physiologic excretion into the genito-urinary system, and interestingly tracer accumulation was seen in the inferior vena cava and ilio-femoral veins which is a non-physiological site for tracer accumulation. The uptake corresponded to a large venous thrombus which was confirmed by a venous Doppler.

Background: Beta blockers have been used in the treatment of hypertension, since last four decades and are widely accepted as the first-line treatment for hypertension. Nebivolol, a third generation ?-blocker has highest ?1 selectivity and is devoid of intrinsic sympathomimetic activity. Along with peripheral vasodilatation and nitric oxide (NO)-induced benefits such as antioxidant activity and reversal of endothelial dysfunction, nebivolol promotes better protection from cardiovascular events. The objective of the study was to compare the effects of atenolol and nebivolol on both blood pressure and lipid profile in patients of mild to moderate hypertension.Methods: This was a prospective, randomized, parallel, open labelled study. Patients were recruited from the medicine out-patient department (OPD) and cardiology OPD. A total of 100 patients were enrolled in the study. 50 patients were allocated to atenolol group and 50 patients to nebivolol group. BP and baseline investigations such as lipid profile were performed. Tests to determine lipid profile were performed on the first visit (Week 0) and at 24 weeks. Continuous variables between the two treatment groups were analyzed by unpaired t-test. Efficacy endpoints within the group were analyzed by using paired t-test.Results: All the lipid levels except HDL-C were increased with atenolol therapy. At 24 weeks, atenolol therapy led to increase in LDL-C, VLDL-C, TC and TG which was highly significant (p<0.0001). HDL levels were decreased at 24 weeks which was also statistically highly significant (p<0.0001). The mean values of lipids in nebivolol group at baseline and at 24 weeks. At 24 weeks, nebivolol therapy led to changes in LDL-C, VLDL-C, HDL-C, TC and TG which was not statistically significant (p>0.05).Conclusions: From study it can be concluded that atenolol and nebivolol are equally effective in reducing BP but atenolol worsens lipid profile as compared to nebivolol.
ABSTRACT
Multiple endocrine neoplasia type 1 (MEN1) syndrome is characterized by combined occurrence of tumors of endocrine glands including the parathyroid, the pancreatic islet cells, and the anterior pituitary gland. Parathyroid involvement is the most common manifestation and usually the first clinical involvement inMEN1 syndrome, followed by gastroentero-pancreatic neuroendocrine tumors (NETs). Here we present a case where the patient initially presented with metastatic gastric NET and a single parathyroid adenoma was detected incidentally on â¶â¸Ga-DOTANOC PET/CT done as part of post ¹â·â·Lu-DOTATATE therapy (PRRT) follow-up. Further ¹â¸F-fluorocholine PET/CT showed four adenomas for which the patient subsequently underwent subtotal parathyroidectomy.

Acetaminophen is a very commonly used analgesic and antipyretic drug across various age groups. Although mild to moderate cutaneous reactions have been reported quite frequently, serious reactions like Stevens –Johnson syndrome and Toxic epidermal necrolysis (TEN) are very rare. We report the case of a 10 year old child who had TEN after ingestion of tablet acetaminophen. This case report highlights the need to be critically aware of this rare and serious adverse effect of this commonly used over the counter drug.
ABSTRACT
Background: The present study was planned to evaluate the preventive effects of gamma linolenic acid (GLA) on STZ induced diabetic neuropathy Methods: Streptozotocin (STZ) induced diabetic neuropathy in rats was monitored by measuring blood sugar levels, body weight, motor nerve conduction velocity (MNCV) and nociception. Forty rats were divided into 4 groups of 10 each. Group 1: control (vehicle), Group 2: STZ (50 mg/kg, i.v., single injection), Group 3: Gamma linolenic acid (50 mg/ kg, p.o., daily + STZ), Group 4: STZ + Insulin (4 units/kg, s.c., bid). Similar protocol was used for other parameters also. Results: Gamma linolenic acid pretreatment failed to reduce blood sugar levels in diabetic rats but prevented deterioration of motor nerve conduction velocity as compared to STZ diabetic rats. A significant weight gain was observed in STZ diabetic rats pretreated with GLA as compared to rats received STZ alone. Hyperalgesia induced by STZ was antagonized by GLA Conclusions: Thus gamma linolenic acid prevents the development of neuropathic changes induced by STZ in rats.
ABSTRACT
Objective: To investigate chick pancreatic lipase inhibitory activities of the Abroma augusta (A. augusta). Methods: A. augusta was first extracted with methanol and subjected to phytochemical screenings. Quantitative estimation of flavonoids, phenolics and alkaloids was done. Pancreatic lipase from chick pancreas was isolated and used as substrate for anti-lipase studies. Results:A. augusta extract effectively inhibited concentration dependent lipase activity, whereby extract at concentration 100 μg/mL inhibited 88.6% enzyme activity. Conclusions: From these results, it could be concluded that A. augusta can be used as a potential source anti-lipase agents.
ABSTRACT
Tuberculosis is highly prevalent amongst children in India. Contact survey has not received much attention in the Revised National Tuberculosis Control Program guidelines. This study was conducted to look for tuberculosis in asymptomatic family members of pediatric tuberculosis patients at a government hospital attached to a medical college in Central India. 168 siblings and 162 parents of 86 index cases of tuberculosis were studied. 64 tuberculosis infected siblings and 7 sputum positive parents were identified.
ABSTRACT
By convention, soft tissue tumors include the peripheral nerve sheath tumor (PNST) although they arise from neuroectoderm. PNSTs display a wide spectrum of morphology and biological behavior. Malignant transformation in benign tumors, especially neurofibroma, is an acknowledged phenomenon.This article describes clinico-pathological features of 126 PNSTs with their morphological variants and those associated with neurofibromatosis 1 (NF1) encountered in a single center over a 6-year period. Benign PNSTs were more common [118 (93.65%)] when compared with their malignant counterparts [8 (6.34%)]. Histological variants including plexiform schwannomas and diffuse, plexiform and pigmented forms of neurofibromas, though rare, were observed. Eleven (8.73%) patients with NF1 showed a strong association with plexiform neurofibroma. A malignant transformation in pre-existing neurofibroma was seen in 1 patient with NF1. This series highlights the clinico-pathological spectrum of PNSTs, their morphological variants and the incidence of associated NF1. The importance of detecting plexiform variants lies in their vastly different prognostic implications particularly when occurring in the setting of NF1.
