Impact of fermented organic formulations combined with inorganic fertilizers on broccoli (Brassica oleracea L. var. italica Plenck) cv. Palam Samridhi.

A two-year field experiment (2018-19 and 2019-20) was laid out in a randomized complete block design (RCBD) with a spacing of 60 × 45 cm involving three replications with ten treatments having cow manurial amendments along with integrated nutrient management in a plot size of 3.0 m × 1.8 m. The effect of the integration of cow manurial amendments and mineral fertilizers on soil fertility, nutrient uptake, yield, and economics of broccoli was studied. The experiment was laid out during the rabi season in the mid-hills of Himachal Pradesh. T8 [90% RDN (112.5 N: 67.5 P: 46.8 K kg/ha) + 5% jeevamrit (1.5 l/m2) + 5% jeevamrit foliar spray] obtained the greatest organic carbon (20.93 g kg-1), available N (375.13 kg ha-1), P (48.46 kg ha-1), K (260.53 kg ha-1) in the soil as well as more uptake of N (60.58 kg ha-1), P (7.25 kg ha-1) and K (37.88 g ha-1) by the plants. Further, this treatment obtained the greatest value for yield (186.77 q ha-1 and 12.44 kg plot-1), net income (₹ 245840) and cost-benefit ratio (1.93). Outcomes of this investigation suggested that combined usage of cow manure, jeevamrit, beejamrit, and ghanjeevamrit with inorganic fertilizers proved to be useful for enhancing soil health, increasing nutrient uptake, and ensuring sustainable production of broccoli.

Metastatic Malignant Phosphaturic Mesenchymal Tumor of Mandibular Alveolus: a Rare Case Report and Review of Literature.

Malignant phosphaturic mesenchymal tumors (PMT) of the head and neck region are extremely rare, which cause paraneoplastic syndrome characterized by hypophosphatemia and osteomalacia. We report a 48-year-old gentleman who had persistent knee and calf pain associated with weakness in lower limbs on presentation. He had hypophosphatemia and elevated FGF-23 and 68 Ga-DOTANOC PET scan showed soft tissue density mass with increased peripheral radiotracer uptake in the left mandibular alveolus and adjoining floor of the mouth, revealing the primary tumor. It also showed a non-avid, histological inconclusive nodule of 17 × 12 mm in size in the lower lobe of the right lung. The patient was treated with composite resection and bilateral level I-III neck dissection with microvascular free fibula osteocutaneous flap mandibular reconstruction. Histopathological examination showed malignant PMT with positive soft tissue margins and bilateral metastatic cervical lymphadenopathy. The patient received adjuvant radiation therapy and sequential post therapy scans showed no evidence of locoregional disease, however showed progressive functional pulmonary metastatic disease which did not respond to chemotherapy. We also made a brief review of literature of head and neck malignant PMT focusing on presentation, primary and adjuvant treatment, and response to treatment.

Head and Neck Surgery During COVID-19 Pandemic: Experience from a Tertiary Care in India.

Head and neck pathologies requiring surgical intervention are considered a high-risk subsite in the context of COVID-19 pandemic by virtue of its close proximity to the mucosa of the upper aerodigestive tract. Retrospective review of all head and neck surgical procedures is undertaken during the pandemic from 23rd April 2020 to 30th September 2020. One hundred procedures were performed on 98 patients. COVID-19 status determined by SARS-Cov-2 RT-PCR at baseline was negative for 81, positive in 8 and unknown in 11. The RT-PCR negative subgroup included 40 diagnostic procedures and 41 ablative and or reconstructive procedures for head and neck neoplasms. None of the patients or health-care workers converted to COVID-19-positive status during the duration of the hospital stay. There were no cases with 30-day mortality. Clavien-Dindo grading for postoperative complications was as follows: 1-4, 2-12, 3a-2, 3b-1. Eleven patients with unknown COVID-19 status at baseline underwent emergency tracheostomy in a COVID-19 designated operating room for upper airway obstruction secondary to head and neck cancer. Of the 8 procedures conducted on known cases of COVID-19, 6 were tracheostomies performed for COVID-19 ARDS. The rest were maxillectomy for acute invasive mucormycosis and incision and drainage for parotid abscess. A matched-pair analysis was performed with similarly staged historical cohort operated during January to December 2016 to compare peri-operative complication rates (Clavien-Dindo Score). Incidence of complication with higher Clavien Dindo Score (>/=3a) was found to be lower in those patients operated during the pandemic (p=0.007). By meticulous preoperative COVID-19 screening and isolation, head and neck surgical procedures can be continued to avoid delay in diagnosis and treatment without jeopardising the risk of transmission of COVID-19 to the patients or health-care workers.

68Ga-Prostate-Specific Membrane Antigen PET/CT in Sinonasal Glomangiopericytoma-Exploring Theranostic Avenues!

ABSTRACT: Prostate-specific membrane antigen (PSMA) is expressed in the tumor-associated endothelial neovasculature of various nonprostatic benign and malignant neoplasms. A 25-year-old man with recurrent sinonasal glomangiopericytoma underwent whole-body 68Ga PSMA PET/CT to explore its theranostic role. There was intense PSMA uptake (SUVmax = 23.9) noted in the tumor. The uptake was more than that of the salivary glands, lacrimal glands, aorta, spleen, and the liver. Performance of PSMA PET/CT in sinonasal glomangiopericytoma opens up new frontiers concerning radiological imaging, early recurrence identification, and perhaps even radioligand therapy of residual/recurrent tumors.

Prevalence of Synchronous ESCN in Head and Neck Cancer: A Single-Institution Perspective.

OBJECTIVES: The primary objective was to determine the prevalence of synchronous esophageal squamous cell carcinoma in head and neck squamous cell carcinoma (HNSCC) patients. The secondary objective was to determine risk factors for the development of synchronous esophageal squamous cell carcinoma (ESCN). STUDY DESIGN: Cross sectional observation study. METHODS: A prospective cross sectional, observational study on consecutive 300 newly diagnosed oral cavity, oropharynx, hypopharynx, and laryngeal squamous cell carcinoma patients who underwent trans-nasal esophageal endoscopy with white light imaging and narrow band imaging. RESULTS: Among 300 patients, index HNSCCs were located in the oral cavity (n = 154, 51.3%), oropharynx (n = 63, 21%), larynx (n = 53, 17.7%), and hypopharynx (n = 30, 10%). The prevalence of synchronous ESCN was 2.7% (n = 8), including four low-grade, two high-grade dysplasia, and two squamous cell carcinomas. On logistic regression analysis, moderate to heavy alcohol consumption (OR 8.7, P = .01) and primary HNSCC involving supraglottis [(OR 12.5, P = .02) were risk factors for synchronous ESCN. The association of pyriform sinus carcinoma and synchronous ESCN was of borderline significance (P = .054, OR 10.92). CONCLUSION: The prevalence of synchronous ESCN in HNSCC was 2.7%. Routine trans-nasal esophagoscopy should be performed in all newly diagnosed patients with carcinoma of the supraglottis and pyriform sinus, and those with consumption of moderate to heavy alcohol for the screening of synchronous ESCN.

Beneficial effect of candesartan and lisinopril against haloperidol-induced tardive dyskinesia in rat.

INTRODUCTION: Tardive dyskinesia is a serious motor disorder of the orofacial region, resulting from chronic neuroleptic treatment of schizophrenia. Candesartan (AT1 antagonist) and lisinopril (ACE inhibitor) has been reported to possess antioxidant and neuroprotective effects. The present study is designed to investigate the effect of candesartan and lisinopril on haloperidol-induced orofacial dyskinesia and oxidative damage in rats. MATERIALS AND METHODS: Tardive dyskinesia was induced by administering haloperidol (1 mg/kg i.p.) and concomitantly treated with candesartan (3 and 5 mg/kg p.o.) and lisinopril (10 and 15 mg/kg p.o.) for 3 weeks in male Wistar rats. Various behavioral parameters were assessed on days 0, 7, 14 and 21 and biochemical parameters were estimated at day 22. RESULTS: Chronic administration of haloperidol significantly increased stereotypic behaviors in rats, which were significantly improved by administration of candesartan and lisinopril. Chronic administration of haloperidol significantly increased oxidative stress and neuro-inflammation in the striatum region of the rat's brain. Co-administration of candesartan and lisinopril significantly attenuated the oxidative damage and neuro-inflammation in the haloperidol-treated rat. CONCLUSIONS: The present study supports the therapeutic use of candesartan and lisinopril in the treatment of typical antipsychotic-induced orofacial dyskinesia and possible antioxidant and neuro-inflammatory mechanisms.
