ABSTRACT
Introduction: Myxoid soft‑tissue tumors are a diverse group of tumors which have similar histomorphology but have varied geneticsequence and clinical outcome, hence differentiating and diagnosing them is a challenge for any pathologist. This study describes the varioushistomorphological spectrum and vascular pattern of various myxoid soft‑tissue tumors. Materials and Methods: This was a retrospective and prospective observational study of myxoid soft‑tissue tumors over a period of 13 years. A total of 224 cases with myxoid morphology were included and were examined morphologically with a special focus on the vascular pattern. SPSS v 24 was used for statistical analysis. Results: The predominant lesions were benign in 164 (73.21%) cases, followed by malignant lesions in 43 (19.19%) cases and intermediate lesions 17 (7.58%) cases. Both benign and malignant lesions showed a male preponderance and were seen to arise predominantly from the extremities. The most common benign myxoid lesions in this study were of neural origin with myxoid neurofibroma constituting 65 (29. 01%) cases, followed by schwannoma 38 (16.9%) cases. Myxoid dermatofibrosarcoma protuberans was the most common intermediatelesion. Tumors with adipocytic differentiation were the predominant lesions among the malignant group, i.e myxoid liposarcoma seen in 17 (7.5%) cases. Conclusions: Vascular pattern in the myxoid lesions are subtle yet crucial in arriving at a histo‑morphological diagnosis. Further studies correlating the vascular pattern with the genetic profile of these tumours can help arriving at a histo‑morphological diagnosisof myxoid lesions.
ABSTRACT
Introduction:Head‑and‑neck cancer (HNC) treatments are elusive, and the hunt for an appropriate radiation strategy continues.Hypofractionation has the potential to provide several advantages, including a shorter overall duration that reduces rapid repopulation, dosage escalation with a higher biologically effective dose, and patient convenience. Hypofractionation is also beneficial in minimizing the danger of catching an infectious agent by reducing the number of hospital visits during the height of the COVID‑19 epidemic. Materials and Methods: Between January 2020 and August 2021, 120 patients with squamous cell carcinoma of the head‑and‑neck subsites were randomly allocated to either the hypofractionated arm A (n = 60) or the standard fractionation arm B (n = 60) with concomitant treatment. Results:Locoregional tumor response, acute and late toxicity, and compliance were the study’s endpoints. The normal tissue toxicities of each patient undergoing radiation were monitored weekly. Clinical and radiographic evaluations of locoregional control were conducted. Conclusion:Hypofractionation effectively overcomes tumor repopulation in rapidly growing tumors such as HNC, and we conclude in our study that the hypofractionated chemoradiation schedule appears to be more efficacious, with relatively superior locoregional control when compared to conventional chemoradiation with comparable normal tissue toxicities and compliance
ABSTRACT
Injuries due to a lightning strike are uncommon presentations in the emergency department. Common injuries caused by lightning include burns, muscle pains, cardiac arrest, hearing loss, seizures, behavioral changes and ocular cataracts. We report a case of a 26-year-old primigravida with history of 3 months of amenorrhea who was struck by lightning as she was standing beside a tree. It left her unconscious, immediately after which she was taken to the emergency department of Maharana Bhupal Govt Hospital (MBGH Hospital), Udaipur, Rajasthan. Entry wound was from right ear and the exit wound was on abdomen. Examination confirmed linear first- and superficial second-degree burns. The electrocardiogram (ECG) showed deep and symmetrical T-wave inversion in precordial and lateral leads. There was an associated elevation of troponin T levels (peak: 432 ng/L), suggestive of myocarditis. On otoscopic examination, she was found to have rupture of tympanic membrane bilaterally. A transthoracic echocardiography revealed reduced ejection fraction of the left ventricle to 25% with global left ventricle hypokinesia, moderate mitral regurgitation and tricuspid regurgitation. This case aims to raise awareness among the healthcare providers regarding multiple organ involvement in lightning injury.

ABSTRACT
Scrub typhus, a rickettsial disease endemic in several parts of India, usually presents with acute symptoms. It is caused by small intracellular Gram-negative bacteria belonging to the Rickettsiaceae family. Optic neuritis and lateral rectus palsy may be associated with a range of autoimmune disorders, infectious diseases and raised intracranial tension. In this case, we report optic neuritis and lateral rectus palsy induced by Orientia tsutsugamushi. We report a case of a 23-year-old woman presenting with complaints of high-grade fever, vomiting and generalized swelling since 5 days. During this febrile period, on 4/10/2021, she complained of difficulty in vision and double vision. She was found to be positive for scrub typhus on 5/10/2021. Optic neuritis was diagnosed on the basis of ophthalmologic examination and magnetic resonance imaging (MRI) brain. Investigation was done to rule out autoimmune disorders (vasculitis and connective tissue diseases). Rickettsial optic neuritis was confirmed by detection of specific antibodies in serum and the negativity of other serologic tests. Fever, eschar, history of tick exposure and supportive diagnostic tests usually lead to the diagnosis. This case aims to raise awareness among the healthcare providers for this type of association. Scrub typhus should be included in the differential diagnosis when a patient presents with fever with or without eschar and isolated or multiple cranial nerve palsy
ABSTRACT
BACKGROUND: Rheumatic heart disease is a major health problem in our country. There is evidence from South India that its prevalence is declining. This study attempts to confirm whether this is so in North India as well. METHODS AND RESULTS: A total of 118,212 (68,357 males, 49,855 females) schoolchildren in the age group of 4-18 years were examined for the presence of heart disease. Evaluation, including echocardiography, confirmed that of a total of 389 suspected to have heart disease, 61 had rheumatic heart disease. Thus, the prevalence of rheumatic heart disease was found to be approximately 0.5 per 1000 children. CONCLUSION: In a fairly large school survey conducted by us, the prevalence of rheumatic heart disease turned out to be approximately 0.5 per 1000 children. This is the lowest figure reported from our country so far and confirms the decline of this disease in our country.
