Management of Multi Drug Resistance Tuberculosis in the Field: Tuberculosis Research Centre Experience

Setting: Multi-drug TB resistant (resistant to isoniazid and rifampicin) patients identified from a rural and urban area. Objective: To study the feasibility of managing MDR TB patients under field conditions where DOTS programme has been implemented Methods: MDR TB Patients identified among patients treated under DOTS in the rural area and from cases referred by the NGO when MDR TB was suspected form the study population. Culture and drug susceptibility testing were done at Tuberculosis Research Centre (TRC). Treatment regimen was decided on individual basis. After a period of initial hospitalization, treatment was continued in the respective peripheral health facility or with the NGO after identifying a DOT provider in the field. Patients attended TRC at monthly intervals for clinical, sociological and bacteriological evaluations. Drugs for the month were pre-packed and handed over to the respective center. Results: A total of 66 MDR TB patients (46 from the rural and 20 from the NGO) started on treatment form the study population and among them 20 (30%) were resistant to one or more second line drugs (Eto, Ofx, Km) including a case of “XDR TB”. Less than half the patients stayed in the hospital for more than 10 days. The treatment was provided partially under supervision. Providing injection was identified to be a major problem. Response to treatment could be correctly predicted based on the 6-month smear results in 40 of 42 regular patients. Successful treatment outcome was observed only in 37% of cases with a high default of 24%. Adverse reactions necessitating modification of treatment was required only for three patients. Implications Despite having reliable DST and drug logistics, the main challenge was to maintain patients on such prolonged treatment by identifying a provider closer to the patient who can also give injection, have social skills and manage of minor adverse reactions

Search for new physics in events with two soft oppositely charged leptons and missing transverse momentum in proton-proton collisions at root s=13 TeV

A search is presented for new physics in events with two low-momentum, oppositely charged leptons (electrons or muons) and missing transverse momentum in proton-proton collisions at a centre-of-mass energy of 13TeV. The data collected using the CMS detector at the LHC correspond to an integrated luminosity of 35.9 fb(-1). The observed event yields are consistent with the expectations from the standard model. The results are interpreted in terms of pair production of charginos and neutralinos ((chi) over tilde (+/-)(1) and (chi) over tilde (0)(2)) with nearly degenerate masses, as expected in natural supersymmetry models with light higgsinos, as well as in terms of the pair production of top squarks ((t) over tilde), when the lightest neutralino and the top squark have similar masses. At 95% confidence level, wino-like (chi) over tilde (+/-)(1)/(chi) over tilde (0)(2) masses are excluded up to 230GeVfor a mass difference of 20GeV relative to the lightest neutralino. In the higgsino-like model, masses are excluded up to 168GeV for the same mass difference. For (t) over tilde pair production, top squark masses up to 450GeVare excluded for a mass difference of 40GeV relative to the lightest neutralino. (C) 2018 The Author(s).

Unusual metastatic presentation of carcinoma hypopharynx

Cutaneous metastases from hypopharyngeal cancers is rare constituting about 0.8-1.3% and represent a sub-group of head and neck cancer patients who have very poor prognosis even when treated. We report a case of 65-year-old male diagnosed as carcinoma hypo pharynx stage IV who was on radiotherapy when he developed cutaneous metastasis over the chest wall, which initially presented as small nodules and later progressed into a proliferative lesion. Patient received further radiation to the metastatic lesion, but the disease was progressive, demonstrating that head and neck squamous cell cancer patients with skin metastasis fare poorly
