Introduction: Antiepileptics and antidepressant medications are known for managing neuropathic pain. We aim to compare the effects of pregabalin with low‑dose amitriptyline and gabapentin with low‑dose amitriptyline in managing neuropathic pain in cancer patients undergoing palliative care. Materials and Methods: We conducted our study on 160 cancer patients who were having neuropathic pain and were undergoingpalliative care treatment in our institute. It was a hospital‑based, randomized, tertiary cancer center‑based observational study. After taking approval from the institutional ethics committee and taking written informed consent from patients, the patients were divided into two groups and the effect of medicines on incidence of neuropathic pain was observed; the incidence of burning sensation and the incidence of adverse effects of medications were also analyzed. Statistical analysis was done using paired t‑test and SPSS version 20 software. Results: The onset of relief in pain was earlier in the pregabalin group as compared to the gabapentin group. There was more reduction in a burning sensation in the pregabalin group as compared to the gabapentin group. The incidence of headaches was the same in both groups. Nausea and vomiting were more in the pregabalin group but the overall difference in adverse effects was not statistically significant (P > 0.05) Conclusions: In the management of neuropathic pain in cancer patients who are undergoing palliative care, a combination of pregabalin with amitriptyline was found to be more effective in pain relief than gabapentin with amitriptyline.

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.

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

Introduction: Chemo-radiation preceded by induction chemotherapy is reported valuable alternative to laryngectomy in laryngeal cancer for larynx preservation.This study was performed to assess the influence chemo radiation on preservation of larynx. Materials and Methods: Two hundred and fifty sequential patients treated from January 2012 to December 2012 in our institute were reviewed and who were available for follow-up in this retrospective study. Total dose of 66-70 Gray was used at 2 gray per fraction daily for five days week were used. Larynx preservation rate at3 years of median follow-up were analyzed. Results: Among 250 patients, larynx preservation was possible in 170 patients (68%). With chemo-radiation, excellent preservation of larynx was achieved in stage II (78%) disease, while in advanced stage III and stage IVA, larynx preservation was67.06% and 64.35%, respectively. Conclusion: Chemo-radiation (either neoadjuvant chemotherapy followed by chemoradiation or concurrent chemo-radiation) has better larynx preservation rate in early as well was advanced laryngeal cancer patients.

Introduction: Concurrent chemo-radiation is the main treatment in locally advanced cervical cancer. The change of bladder and rectum volume may lead to change in the positions of these structures and target volume during MUPIT implant which may lead to variation in dose to the organ at risk and target. Materials and Methods: Ten patients of gynecological malignancy were included. MUPIT template was positioned under anesthesia. CT scan was done for the contouring of bladder, rectum, and target and for planning purpose which generates plan (P1). CT scan was repeated before the third fraction of the treatment (CT2). The resultant plan (P2) was analyzed qualitatively and quantitatively. Results: Bladder volume variations of 88.18% to -68.15% were noted. This change in volume lead to differences in the maximum dose in bladder between fractions. The maximum dose variation ranged from 62.53% to -21.49%. The rectal volume variation ranges 11.71% to -46.20% due to the rectal filling. High variation in maximum dose to the rectum were observed which might be due to rectal filling. CTV volume is increased by 19.48% while in other by 19.05% and in all other patients the volume is decreased. CTV volume maximum decreased by 30.54% which might be due to decrease in edema developed during procedure. The volume variation in CTV is in range of19.48% to -30.54%. Conclusion: It is proposed that re-planning using repeat CT scan is required before third fraction implementation.

Purpose/Objective(s): In India > 1 million new cases of cancer diagnosed every year. 40-50% of these cases are of head and neck cancer because of tobacco overuse. In our institute we have almost 1000-1300 new cases of Carcinoma Buccal Mucosa reported every year. From which 70-75% are surgically operable. For post-operative Radiotherapy treatment, we treat most of our patients by 2 Dimensional conventional treatments. Purpose of this study is to assess toxicity & long term results of postoperative carcinoma buccal mucosa cases treated by 2 Dimensional conventional treatment planning. Materials/Methods: From January 2009 to January 2012, almost 1980 postoperative cases of Carcinoma Buccal mucosa were referred for radiotherapy treatment. From which 1584 cases were suitable for postoperative 2 Dimensional Conventional planning. In selected cases, 71%, 18%, 11% cases were of Stage IV, III, II (close margin) respectively. Postoperative chemotherapy and radiotherapy was indicated in 475 patients. For all patients Plaster of Paris cast was prepared & X-ray was taken on Simulator machine. Target volume was drawn on x-ray & treatment plan generated on contour drawn with 90-95% isodose line covering the target, with hot spot of +10% on 2D Plato treatment planning system. All patients were treated with unilateral Anterior Posterior Lateral wedge pair technique for buccal mucosa and unilateral lower neck was given in indicated patients. Dose prescribed was 60 Gy/30#, 2Gy/#, 5 days a week, total 6 weeks treatment. Treatment plan verified on day 2 and treatment started. In patients where postoperative chemotherapy and radiotherapy was used, chemotherapy was given Cisplatin 30mg/m2 every weekly for 6 weeks. In most of the patients, treatment break was not required. All patients completed treatment successfully. Patients were assessed for locoregional control, acute & late toxicity and followed up for 3 years for disease free survival and overall survival. Results: Grade II & III acute mucositis was 82% & 18% respectively in 1109 patients who received only postoperative radiotherapy. For patients who received postoperative radiotherapy and chemotherapy Grade II and Grade III acute mucositis was seen in 75% & 25% respectively and side effects related to Cisplatin were managed conservatively. Almost all patients had Grade II skin reactions. Grade III skin reactions were observed in 8% of patients on post operative radiotherapy alone and 19% of patients on postoperative radiotherapy and chemotherapy but were manageable. All patients tolerated treatment well. For 1584 patients, follow up dropout rate was 20%. None of the patients developed significant late toxicity. As opposite parotid spared, no late complication of xerostomia observed. For 1268 patients, 1-, 2-, 3- year locoregional control rates were 82%, 75%, 68% respectively. Disease free survival rate was 63% (799 patients) & overall survival was almost 55% (697 patients) at median follow up for 40 months. Conclusion: 2D Conventional Radiotherapy Treatment Planning in our set up has shown very good results with almost 50% survival rates. It is less toxic treatment with fewer complications & less time consuming. It is highly cost effective treatment approach & results are very much encouraging.

Objective: To study the prescription patterns in a psychiatry outpatient department in a tertiary care teaching hospital. Methodology: An observational study was conducted from August 2007 to January 2008 in a psychiatry outpatient department in a tertiary care teaching hospital. A total of 300 patients suffering from 3 major classes of psychiatric illnesses (Schizophrenia & other psychotic disorders, Mood disorders, Anxiety disorders as diagnosed by Psychiatrists). The data from the prescription card of the patients was noted in a structured pro forma. Results: Prescription analysis showed that average number of drugs per encounter (Mean ± SD) was 2.53 ± 0.97. Not a single drug was prescribed by generic name. Injection was prescribed in 5% of prescriptions. 67.41% of drugs were prescribed from hospital formulary while 60.03% of drugs were actually dispensed from the hospital pharmacy. In Schizophrenia and other psychotic disorders, most common antipsychotic drug prescribed was Trifluoperazine followed by Chlorpromazine. In mood and anxiety disorders, most common drug prescribed was Imipramine and Chlordiazepoxide respectively. Conclusion: The present study could serve as a platform upon which further studies in prescription analysis of psychotropic drugs can be undertaken to investigate the scope for improvement in prescribing practices in psychiatry.
RÉSUMÉ
Background: In developing countries like ours with a large number of tuberculosis (TB) cases and limited resources, the diagnosis of TB relies primarily on smear microscopy for Acid Fast Bacilli (AFB) but its sensitivity is limited in paucibacillary cases. Aim: To evaluate the increase in efficacy of smear microscopy when smears are prepared from clinical samples after concentration by Petroff’s method and stained by Auramine O (AO) fluorescent dye as against Ziehl Neelsen (ZN) staining of similar taking culture as the gold standard. Methods: Smears were prepared from 393 clinical samples both by direct and after Petroff’s concentration and examined by fluorescent microscopy and Ziehl Neelsen method .The concentrated material was also cultured on Lowenstein Jensen media and the results of the two microscopy methods were compared with the culture results taken as the gold standard. Results: Mycobacterial growth was detected in 137(35.77%) specimens, out of which three were non-tubercular mycobacteria. Using culture as the reference method, the sensitivity of direct staining was 55.55% for ZN and 71.85% for AO. Direct fluorescent microscopy detected 9.29% paucibacillary sputum samples that were missed on ZN staining. On concentration, the sensitivity increased by 6.67% for ZN and 11.11% for AO. The sensitivity of AFB smear microscopy increased by 27.41% and was statistically significant (p=<.001) when both methods were combined. The specificity was 99.19% for both ZN and AO. Conclusion: Fluorescent microscopy has higher sensitivity and comparable specificity which is further enhanced by concentration. Now with the advent of newer inexpensive Light Emitting Diode (LED) based fluorescent microscopes (FM), which are easier to use, fluorescent microscopy can be widely used even in peripheral laboratories where culture facilities are not available.
