Lymphadenovarix in the axilla – an unusual presentation of filariasis

Clinical manifestations of lymphatic filariasis depend on the area of lymphatic involvement and the duration of infection. A 21 year old man, resident in a filariasis endemic region, presented with multiple matted lymph nodes with cystic areas forming a large mass in his left axilla. An ultrasound scan of the axilla using a 7.5 MHz transducer revealed grossly dilated lymphatics but no filarial dance sign. Fine needle (21 G) aspiration cytology (FNAC) from the dilated lymphatics and solid areas in the lymph node mass revealed multiple microfilariae in a background of reactive lymphoid cells. Peripheral blood smears revealed microfilaremia with significant eosinophilia. Diagnosis of left axillary Bancroftian lymphadenovarix was made. On the administration of oral diethylcarbamazine, the diameter of the lymphatic vessels in the lymphadenovarix reduced considerably in size and microfilaremia disappeared. We report this case because axillary lymphadenovarix is a rare presentation of filariasis. This case is also unique since microfilariae were demonstrated in the fluid aspirated from the dilated lymphatics of the lymphadenovarix in the absence of live adult worms

Merging fragments of classical logic

We investigate the possibility of extending the non-functionally complete logic of a collection of Boolean connectives by the addition of further Boolean connectives that make the resulting set of connectives functionally complete. More precisely, we will be interested in checking whether an axiomatization for Classical Propositional Logic may be produced by merging Hilbert-style calculi for two disjoint incomplete fragments of it. We will prove that the answer to that problem is a negative one, unless one of the components includes only top-like connectives.Comment: submitted to FroCoS 201

Two types of materials, L-arginine phosphate (LAP) and doped triglycine sulfate (TGS), are examined for their growth characteristics and relevant properties for second harmonic generation and IR detector applications, respectively

Spontaneous cecal perforation secondary to acute fulminant gastroenteritis: report of a rare case

Acute gastroenteritis and food poisoning are the two common diagnoses considered when two or more family members present with vomiting, diarrhea, and abdominal pain. Acute fulminant gastroenteritis is usually seen in immunocompromised patients and is associated with significant morbidity and mortality. We report a 15-year-old boy who presented with acute onset abdominal pain, vomiting, and diarrhea, along with three other family members. He developed abdominal distension and signs of hollow viscus perforation after 3 days; by that time he had developed  respiratory distress requiring ventilatory assistance. During laparotomy, a 1-cm cecal perforation with feculent peritoneal contamination was noted. Limited ileocolic resection and ileostomy was performed and ileostomy closure was carried out at 6 weeks. This case is being reported to highlight the unusual presentation of fulminant gastroenteritis, leading to spontaneous cecal perforation.Keywords: acute gastroenteritis, fulminant gastroenteritis, spontaneous cecal perforatio

Carbon emissions and radiative forcings from tundra wildfires in the Yukon–Kuskokwim River Delta, Alaska

Tundra environments are experiencing elevated levels of wildfire, and the frequency is expected to keep increasing due to rapid climate change in the Arctic. Tundra wildfires can release globally significant amounts of greenhouse gasses that influence the Earth's radiative balance. Here we develop a novel method for estimating carbon loss and the resulting radiative forcings of gaseous and aerosol emissions from the 2015 tundra wildfires in the Yukon–Kuskokwim Delta (YKD), Alaska. We paired burn depth measurements using two vegetative reference points that survived the fire event – Sphagnum fuscum and Dicranum spp. – with measurements of local organic matter and soil carbon properties to estimate total ecosystem organic matter and carbon loss. We used remotely sensed data on fire severity from Landsat 8 to scale our measured losses to the entire fire-affected area, with an estimated total loss of 2.04 Tg of organic matter and 0.91 Tg of carbon and an average loss of 3.76 kg m−2 of organic matter and 1.68 kg m−2 of carbon in the 2015 YKD wildfires. To demonstrate the impact of these fires on the Earth's radiation budget, we developed a simple but comprehensive framework to estimate the radiative forcing from Arctic wildfires. We synthesized existing research on the lifetime and radiative forcings of gaseous and aerosol emissions of CO2, N2O, CH4, O3 and its precursors, and fire aerosols. The model shows a net positive cumulative mean radiative forcing of 3.67 W m−2 using representative concentration pathway (RCP) 4.5 and 3.37 W m−2 using RCP 8.5 at 80 years post-fire, which was dominated by CO2 emissions. Our results highlight the climate impact of tundra wildfires, which positively reinforce climate warming and increased fire frequency through the radiative forcings of their gaseous emissions.</p

Postoperative pain relief following abdominal operations: A prospective randomised study of comparison of patient controlled analgesia with conventional parenteral opioids

BACKGROUND: Parenteral opioids are traditionally used for pain management following abdominal operations. Patient Controlled Analgesia (PCA) is replacing the conventional method for postoperative pain relief nowadays. AIMS: To find out the effectiveness of PCA in postoperative pain relief following abdominal operations. SETTINGS AND DESIGN: This prospective randomised study was conducted in the Jawaharlal Institute of Post Graduate Medical Education and Research, Pondicherry, India. MATERIALS AND METHODS: Sixty-two consecutive patients undergoing abdominal operations were randomly divided into PCA group (n=32) who received intravenous PCA morphine and IM group (n=30) who received conventional intramuscular morphine in the postoperative period. Morphine consumption, pain relief, detailed pulmonary function tests and side-effects of morphine were assessed. STATISTICAL ANALYSIS: This was performed by "Epi Info 2000 version 6". Chi-square and Students 't' tests were used to relate the variables. RESULTS: The total morphine consumption of the PCA group was significantly lesser than IM group (mean 30.84 mg versus 37.36 mg P-0.015) and it was less at different intervals in the postoperative period. The PCA group had better pain relief when compared to the IM group (mean pain score 3.42 versus 4.97 P&lt;0.001). Pulmonary function parameters did not show a significant difference at different intervals in the postoperative period except for Peak Expiratory Flow Rate. None of the patients had major morphine-related complications. CONCLUSIONS: Intravenous PCA provides better pain relief with less morphine consumption as compared to the conventional IM method. Recovery of postoperative pulmonary functions showed no significant difference in the two groups apart from Peak Expiratory Flow Rate, which showed significant early recovery in the PCA group

IMECE2008-67935 DYE DOPED CLAD MODIFIED EVANESCENT OPTICAL FIBER (CMEOF) SENSOR ARRAY FOR THE DETECTION OF AQUEOUS-AMMONIA

ABSTRACT We are currently developing pH sensitive dye doped clad modified evanescent optical fiber (CMEOF) sensor array for the detection of aqueous-ammonia. The quasi-distribution of CMEOF ammonia sensors allows efficient measurement of aqueous-ammonia at several locations using a single fiber optic line. CMEOF sensors are fabricated by immobilized pH sensitive dyes in sol-gel and applying the dye doped sol-gel as a thin film around a bare core optical fiber. The CMEOF sensors are then sealed from water using a gas permeable membrane, PDMS-vinyl. The dyes in each CMEOF sensor are tailored to operate at slightly different wavelengths by appropriate choice of dyes. Wavelength-division-multiplexing (WDM) and linear system of equations (LSE) are used to interrogate each CMEOF sensor and determine the concentration of aqueous-ammonia at each sensor location

Complexity and Expressivity of Branching- and Alternating-Time Temporal Logics with Finitely Many Variables

We show that Branching-time temporal logics CTL and CTL*, as well as Alternating-time temporal logics ATL and ATL*, are as semantically expressive in the language with a single propositional variable as they are in the full language, i.e., with an unlimited supply of propositional variables. It follows that satisfiability for CTL, as well as for ATL, with a single variable is EXPTIME-complete, while satisfiability for CTL*, as well as for ATL*, with a single variable is 2EXPTIME-complete,--i.e., for these logics, the satisfiability for formulas with only one variable is as hard as satisfiability for arbitrary formulas.Comment: Prefinal version of the published pape
