This study aims to comprehensively understand the Gosikhurd Dam ecosystem (GDE) ecosystem by employing the Ecopath with Ecosim software (version 6.6.5) to construct a trophic mass balancing model. This model consisted of 16 functional groups of organisms, and their interactions and trophic levels were explored. The study focuses on various performance indicators to assess the ecosystem's maturity and complexity. To achieve these objectives, monthly fish samples were collected from June 2022 to May 2023. Performance indicators such as the connectance index (CI), system omnivory index (SOI), Finn's cycling index (FCI), mean path length (FML), ascendency, overhead, and Shannon diversity index were calculated to assess ecosystem maturity and complexity. The Finn's cycling index (FCI) and the mean path length (FML) were calculated as 1.81 and 2.20, respectively, indicating the ecosystem's responsiveness to environmental changes and overall system health and stability. Ascendency and overhead values were also analysed, with ascendency being relatively higher (41.58%), reflecting a system that utilises less than half of its total capacity. The overhead value (58.42%) indicated that the ecosystem is relatively stable and capable of adapting to external perturbations. Furthermore, the Shannon diversity index was 1.67, illustrating less diversity and validating the ecosystem's immaturity. The study identifies critical species and their roles in shaping the ecosystem dynamics, highlighting the importance of zooplankton, zoobenthos, and tilapia as keystone species. These indices propound that GDE is in its developmental stage and lacks complexity compared to mature ecosystems. The findings provide valuable insights into the current state of the ecosystem and can guide future management and conservation efforts., (© 2024.

Purpose: High-flow nasal cannula (HFNO) reduces the need for invasive mechanical ventilation in COVID-19 patients with hypoxemic-respiratory failure. During HFNO entrainment of room air dilutes the delivered fractional inspiratory oxygen (FiO 2 ), thereby preventing improvement in oxygenation. The placement of a mask over HFNO to improve oxygenation has provided conflicting results. We aimed to determine and compare the effect of placing various mask types over HFNO on oxygen saturation (SPO 2 )., Materials and Methods: In this prospective physiological study 40 patients with COVID-19-associated hypoxemic respiratory failure on HFNO with O 2 concentration <92% were included. The effect of placing different masks over HFNO on oxygenation, respiratory rate, heart rate, blood pressure, patient comfort, and partial pressure of carbon dioxide level (pCO 2 ) was recorded after a prespecified time interval., Results: We observed a significantly higher mean SPO 2 and lower mean respiratory rate on using various study masks over HFNO compared to HFNO alone. On comparing various mask types, the use of N95 masks and nonrebreather (NRB) masks with O 2 showed a significant increase in O 2 concentration and reduction in respiratory rate compared to surgical mask (SM) and NRB without O 2 . The proportion of patients who achieved SPO 2 of >92% was higher with the use of N95 masks (47.5%) or NRB with O 2 (45%) over HFNO compared to SM (35%) and NRB without O 2 (35%). No significant change was observed in heart rate, blood pressure, and CO 2 level with the use of any mask over HFNO., Conclusion: This study demonstrates improvement in oxygenation and reduction in respiratory rate with the use of various masks over HFNO in patients of COVID-19-related hypoxemic-respiratory-failure. Significantly greater benefit was achieved with the use of N95 or NRB with O2 compared to SM or NRB without O2., (© Journal of the Association of Physicians of India 2024.)

Introduction Identification of coronavirus disease 2019 (COVID-19) patients at risk of worse clinical outcomes is crucial to improving patient care. Various biochemical markers have been used to predict outcomes in such patients. We aimed to evaluate the role of serum PCT (procalcitonin) and the utility of PCT clearance (PCTc) in predicting the outcome of patients with COVID-19 illness. Methods We prospectively included 39 patients with severe or critical COVID-19 illness with an age equal to more than 18 years. In addition to routine baseline investigations, serum PCT was measured at admission (PCT1) and day 5 of hospitalization (PCT2). PCTc was calculated using the formula [Formula: see text]. Results We observed that serum PCT at admission was significantly higher in non-survivors (median: 1.9 ng/ml IQR: 0.51-4.23) compared to survivors (median 0.35 (IQR: 0.1-1.2), p 0.002). On serial serum-PCT estimation, non-survivors had persistently elevated serum-PCT (median PCT1:1.9 ng/ml (IQR: 0.51-4.23) to median PCT2: 1.9ng/ml (IQR: 0.83-2.72), p 0.51) than survivors (median PCT1:0.35ng/ml (IQR: 0.1-1.19) to median PCT2: 0.15ng/ml (IQR: 0.05-0.29), p 0.01). However, no difference in serum PCTc was observed between the two groups (median: 35.3% (IQR: 12.5-84.9) in survivors vs. 71.7% (33.3-91.7) in non-survivors, p = 0.165). Conclusion Serum PCT is a potential biochemical marker that could predict outcomes in COVID-19 patients. Measurement of serial serum PCT and estimation of PCT clearance may serve as better predictors than a single value; however, well-designed studies are required to identify the definite role of serum PCT in COVID-19 patients of varying severity., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Mehfooz et al.)

Antiviral combinations have been proposed as treatment for influenza in order to increase the antiviral activity by action at different sites of action as well as obviate the emergence of drug resistance to the commonly used antiviral agents like oseltamivir. Nitazoxanide has been found to exhibit anti-influenza viral activity with clinical benefit in a previous study. We recruited 242 cases of SARI, among whon 67 were confirmed to have influenza viral infection. In a randomized blinded fashion, 34 patients received a combination of nitazoxanide and oseltamivir whereas 33 cases received oseltamivir alone. Clinical parameters were followed in both groups and the nasal swabs were re-tested on day 6 for influenza positivity and the cycle threshold (CT) values. No significant differences were observed in terms of time for resolution of fever, other symptoms, and SOFA scores. Nine patients succumbed during the course of the illness that included three in the oseltamivir group and six in the combination group. All but one of those who expired had an underlying co-morbid illness. Our preliminary data suggest that the addition of nitazoxanide does not improve outcomes in hospitalized patients with influenza. Larger studies are recommended for statistically robust conclusions., (Copyright © 2024 Copyright: © 2024 Indian Chest Society.)

Infections in critically-ill patients caused by extensively-drug-resistant (XDR)-Pseudomonas aeruginosa are challenging to manage due to paucity of effective treatment options. Cefepime/zidebactam, which is currently in global Phase 3 clinical development (Clinical Trials Identifier: NCT04979806, registered on July 28, 2021) is a novel mechanism of action based β-lactam/ β-lactam-enhancer combination with a promising activity against a broad-range of Gram-negative pathogens including XDR P. aeruginosa. We present a case report of an intra-abdominal infection-induced sepsis patient infected with XDR P. aeruginosa and successfully treated with cefepime/zidebactam under compassionate use. The 50 year old female patient with past-history of bariatric surgery and recent elective abdominoplasty and liposuction developed secondary pneumonia and failed a prolonged course of polymyxins. The organism repeatedly isolated from the patient was a New-Delhi metallo β-lactamase-producing XDR P. aeruginosa resistant to ceftazidime/avibactam, imipenem/relebactam and ceftolozane/tazobactam, susceptible only to cefepime/zidebactam. As polymyxins failed to rescue the patient, cefepime/zidebactam was administered under compassionate grounds leading to discharge of patient in stable condition. The present case highlights the prevailing precarious scenario of antimicrobial resistance and the need for novel antibiotics to tackle infections caused by XDR phenotype pathogens., (© 2023.

Background and objective There is a dearth of studies on the clinical presentation of patients with post-pulmonary tuberculosis (PTB) sequelae and its impact on their quality of life (QoL). In light of this, we conducted this study to analyze the clinical profile and QoL in patients with post-PTB sequelae. Methods Patients with a history of treated PTB and evidence of radiological damage were enrolled prospectively from November 2018 till June 2020 to study their clinical profile and QoL as per the eligibility criteria. A detailed clinical history was taken along with posteroanterior-view chest X-rays and CT scans of the thorax with bronchial angiography in patients with hemoptysis. QoL was assessed using the Hindi version of St. George's Respiratory Questionnaire (SGRQ) for which permission was obtained from the St. George's University of London. SGRQ scores were calculated using score calculation algorithms (Microsoft Excel-based) and missing data imputation as recommended by its developer. Results A total of 174 patients were included in the analysis. The analyzed population was relatively younger (mean age: 44.27 years) with BMIs leaning toward the lower side of normal (median: 19.6 kg/m²); the majority of the patients were males (59%) and non-smokers (77%). PTB had been diagnosed clinico-radiologically in the majority (68%) of patients with non-compliance to antitubercular treatment (ATT) being reported by only 9% of patients. Multiple courses of ATT were received by about one-third of patients, mainly on a clinico-radiologic basis. Systemic hypertension (HTN) (11%) and diabetes mellitus (DM) (9%) were the most common comorbidities. The most common symptom complex found was cough, expectoration, and dyspnea (n=102, 59%). At least one incidence of massive hemoptysis was reported by 20% of patients. Bronchial artery embolization (BAE) was performed for moderate to massive hemoptysis in 26% of patients with a success rate of >90%. One-fifth of the study participants required hospitalization for exacerbation of respiratory symptoms with more than half of these (59%) requiring ventilatory support. Health-related QoL was significantly impaired as reflected by a median SGRQ total score of 45.53. The most affected domain of QoL was the activity domain (mean score: 45.47). Females had worse QoL as compared to males (p=0.0062), and so did underweight patients (p=0.048). The prolonged duration of the illness also significantly impaired the QoL (p<0.001, r=0.313). Conclusion The sequelae of PTB are under-recognized even among physicians and are frequently misdiagnosed as active PTB. The QoL is more severely affected due to residual damage. This study highlights the clinical profile of this patient population and underscores the need to recognize post-PTB sequelae as a separate entity. An important remedy to mitigate its long-term consequences is its inclusion and recognition in national and international TB guidelines to facilitate its early identification and promote further research to address its evidence-based management., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Thoker et al.)

Objective: To study bronchoalveolar lavage (BAL) findings in various respiratory diseases in children in Kashmir India., Design: Prospective observational study., Setting: Paediatric department of the tertiary care hospital., Patients: Children of both genders from 1 month to 17 years of age INTERVENTION: All studied patients underwent flexible bronchoscopy and BAL., Outcome Measure: To observe the BAL findings in various respiratory diseases in the studied population., Results: A total of 283 patients underwent BAL procedure. The positive BAL report was received in 131 (46%) patients. Out of these, 55 (42%) patients had positive BAL culture/ microscopy for different bacterial (50) and fungal species ( Candida spp (3), Mucormycosis (1) and Aspergillus (1)). MTB was isolated in 25 (19%) patients. Twenty-three (17.5%) patients had bronchoalveolar lavage fluid (BALF) positive for pulmonary hydatidosis. Foamy macrophages were seen in 13 patients, significant eosinophilia in nine patients and hemosiderin-laden macrophages were seen in three patients., Conclusion: We found BALF a very useful sample for the evaluation of many infective and non-infective respiratory diseases in our region, which otherwise lacks high end diagnostics. 46% of our patients had some abnormalities in the BAL specimen. It provided us with valuable information regarding organism profile and drug sensitivity in case of lung infection. BALF analysis was also found useful in the diagnosis of some non-infective pulmonary disorders like acute eosinophilic pneumonia, aspiration syndromes and bronchial asthma., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Background: The prevalence of pulmonary embolism (PE) in patients of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) varies over a wide range. Early detection and treatment of PE in AECOPD is a key to improve patient outcome. The purpose of the study was to investigate the prevalence and predictors of PE in patients of AECOPD in a high burden region of North India., Materials and Methods: This prospective study included patients of AECOPD with no obvious cause of exacerbation on initial evaluation. Apart from routine workup, the participants underwent assessment of D-dimer, compression ultrasound and venous Doppler ultrasound of the lower limbs and pelvic veins, and a multidetector computed tomography pulmonary angiography., Results: A total of 100 patients of AECOPD with unknown etiology were included. PE as a possible cause of AE-COPD was observed in 14% of patients. Among the participants with PE, 63% (n = 9) had a concomitant presence of lower extremity deep venous thrombosis. Hemoptysis and chest pain were significantly higher in patients of AECOPD with PE ([35.7% vs. 7%, P = 0.002] and [92.9% vs. 38.4%, P = 0.001]). Likelihood of PE was significantly higher in patients who presented with tachycardia, tachypnea, respiratory alkalosis (PaCO2 <45 mmHg and pH >7.45), and hypotension. No difference was observed between the two groups in terms of in-hospital mortality, age, sex distribution, and risk factors for embolism except for the previous history of venous thromboembolism (35.7% vs. 12.8% P = 0.03)., Conclusion: PE was probably responsible for AECOPD in 14% of patients with no obvious cause on initial assessment. Patients who present with chest pain, hemoptysis, tachypnea, tachycardia, and respiratory alkalosis should be particularly screened for PE., Competing Interests: None

Introduction: Patients with sleep-related breathing disorders (SRBD) have various structural and functional abnormalities of the upper airway during sleep which may get reflected on their pulmonary function tests. The aim of the study was to find the correlation between the spirometric indices and snoring, grades of apnea-hypoapnea index (AHI), and STOPBANG. There is scarcity of literature showing correlation of STOP BANG with spirometric variables., Material and Methods: Patient with SRBD fulfilling the inclusion and exclusion criteria were enrolled. The pretest probability sleep score STOPBANG and polysomnography (PSG) were calculated for all the patients. Spirometric indices like forced expiratory volume in one sec (FEV1), forced vital capacity (FVC), postbronchodilator ratio FEVI/FVC (PBDR), and peak expiratory flow rate (PEFR) were studied. Their association with snoring, different grades of obstructive sleep apnea (OSA), and STOPBANG were evaluated using statistical analysis., Results: A total of 70 patients were enrolled. Abnormalities of spirometric indices were found to be common in patients with SRBD but their association with snoring, grades of OSA, and STOPBANG were not statistically significant. There is no statistically significant correlation between body mass index (BMI) and grades of AHI., Conclusion: This study found no statistically significant correlation between spirometric parameters and STOPBANG and degree of AHI. Primary care physicians should be aware that obstructive lung disease does coexist with the sleep disordered breathing but as per this study, their statistically significant association needs further validation., Competing Interests: There are no conflicts of interest., (Copyright: © 2021 Journal of Family Medicine and Primary Care.)

Background: Data regarding the agreement among multiple operators for measurement of quadriceps muscle thickness by bedside ultrasonography (USG) are sparse., Aim: To statistically assess the agreement among 5 operators for measurement of quadriceps muscle thickness on bedside USG., Methods: This was a cross-sectional observational study. The 5 operators of varied experience (comprised of 1 critical care consultant, 2 fellows, and 2 nurses) independently measured quadriceps muscle thickness in triplicate for 45 critically ill patients each, using USG. Intra- and interrater agreement rates among the 5 operators were assessed using intraclass correlation coefficient (ICC) and expressed with 95% confidence interval (CI)., Results: The 5 operators produced a total of 135 readings and 675 observations for ICC calculations to determine the intraoperator and interoperator variations respectively. For intraoperator agreement, the overall ICC (95%CI) was 0.998 (0.997, 0.999) for operator 1, 0.998 (0.997, 0.999) for operator 2, 0.997 (0.995, 0.999) for operator 3, 0.999 (0.998, 0.999) for operator 4, and 0.998 (0.997, 0.999) for operator 5. For interoperator agreement, the overall ICC (95%CI) was 0.977 (0.965, 0.986; P < 0.001) for reading 1, 0.974 (0.960, 0.984; P < 0.001) for reading 2, and 0.975 (0.961, 0.985; P < 0.001) for reading 3., Conclusion: USG measurement of quadriceps muscle thickness was not dependent on clinical experience, supporting training for nurses in it., (©The Author(s) 2019.

Background: Perioperative use of intravenous magnesium as part of multimodal analgesia has been increasing in recent years in an effort to decrease the use of opioids. The aim of this study was to evaluate the effectiveness of magnesium sulfate infusion in lowering analgesic requirement and decreasing the intensity of pain score after cesarean delivery., Methods: Sixty-four patients who underwent cesarean delivery under spinal anesthesia were included in this medical record review: 32 patients received magnesium infusion after cesarean delivery for treatment of mild preeclampsia (Mg group); 32 patients received routine post-cesarean delivery care (control group). Primary outcome was total analgesic consumption and secondary was visual analogue scores (VAS) of pain in each group during the first 24 hours following delivery. These measures were compared using Student's t-tests and Mann-Whitney U-tests., Results: Our study found that patients in the Mg group had significantly less requirement for analgesia than the control group. In the 24 h after cesarean delivery, the Mg group received significantly less intravenous ketorolac (the standard initial rescue analgesic agent) when compared to the control group (79 ± 23 mg vs. 90 ± 0 mg; P = 0.008). The Mg group also received significantly less intravenous morphine equivalents than the control group (median 5.0 (IRQ: 0.0 - 10.0) vs. 9.3 (IRQ: 6.0 - 21.1); P = 0.001) during the first 24 h after cesarean delivery. The Mg group also had significantly lower VAS pain scores than the control group (median 1.75 (IRQ: 0.4 - 2.6) vs. median 3.2 (IRQ: 2.3 - 4.5); P < 0.001)., Conclusions: Our results suggest that magnesium sulfate infusion decreases total analgesic requirements and lowers VAS pain scores during the first 24 h after cesarean delivery.

The effect of addition of multiwalled carbon nanotubes (CNTs) on the piezoelectric properties of polypropylene (PP) monofilaments has been investigated. Various amounts of CNTs (0%, 0.01%, 0.1% and 1% weight ratios) were melt-blended with PP and the resulting nanocomposites were extruded in a continuous process with simultaneous on-line poling to produce monofilaments. Concurrent stretching at a draw ratio of 5:1 and polarisation at applied electric fields of 15 kV of PP/CNT filaments was observed to enhance the piezoelectric properties. The microstructure and crystallinity of the filaments was analysed using scanning electron microscopy (SEM), differential scanning calorimetric (DSC) and Fourier transform infrared spectroscopy (FTIR) techniques. Voltage generation by the CNT-modified PP filaments was determined by the application of predetermined load impact. The results show that the incorporation of CNTs in the PP fibre structure has a considerable impact on the enhancement of piezoelectric properties of the PP filament obtained that the peak voltage generation was almost four fold (from 0.76 V to 2.92 V) when 0.1 wt% of CNTs added into the polymer. This is owing to the fact that carbon nanotubes act as nucleating agent for enhancing the crystallisation during the melt extrusion process.

Self-polarised poly(vinylidene fluoride), (PVDF), films were prepared via a facile phase-inversion technique wherein the polymorphism of the films was controlled from exclusive α- (>90%) to β-phase (>98%) by simply varying the quenching temperature from 100 °C to -20 °C, respectively. At low temperatures, the β-phase crystallites were found to be self-aligned, with the PVDF thin films possessing a high piezoelectric coefficient of up to -49.6 pm V(-1). The extraordinarily high β-phase and piezoelectric coefficient of these PVDF films make them suitable for electroactive and energy harvesting applications.

Background: Chronic obstructive pulmonary disease (COPD) is characterized by an interaction of various environmental influences especially cigarette smoking and genetic determinants. The prevalence of this disease is ever increasing and characterization of the genetic determinants of the disease has been undertaken globally. The 'A disintegrin and metalloprotease 33' (ADAM 33) gene is one candidate gene that has been studied., Objective: Our objective was to investigate whether single nucleotide polymorphisms in ADAM33 gene are associated with COPD in long-term tobacco smokers in the ethnic Kashmiri population of northern India., Materials and Methods: This was a randomized case-control study, which included 78 stable COPD (GOLD stage11-IV) patients, who were compared with 77 age- and sex-matched long-term tobacco smokers (>20 pack years) without any evidence of COPD. Polymorphic analysis for three single nucleotide polymorphisms (SNPs), (T1, T2, and Q1) of the ADAM33 gene was done by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) followed by sequencing. The data were analyzed by descriptive statistics and comparative evaluation was done by parametric/non-parametric tests., Results: The analysis of the T1, T2, and Q1 SNPs, revealed that the frequencies of the T2GG, T1GG, and the Q1AG genotypes were significantly higher in patients with COPD in comparison with the controls (P < 0.001). Similarly, the T1G and T2G allele frequency was higher in the patients than in the controls (p = 0.177 and 0.43, respectively)., Conclusion: Three SNPs of the ADAM33 gene were significantly associated with COPD in the Kashmiri population of India. This study establishes the possible role of ADAM33 SNPS in the causation of COPD. Further studies across different geographical areas in the country will unravel the contribution of this gene in the causation of COPD in India.

Pepper gas is used for riot control in many parts of the world. Yet, its effects on bystanders are largely unreported. We fielded a questionnaire-based survey of 500 bystanders exposed to gas when police used pepper grenades against belligerent 'stone-pelters' in the northern Indian state of Jammu & Kashmir. Of 294 non-combatants who consented to participate in our survey, 97 per cent developed cough and irritation of the throat within few seconds of breathing the pungent smelling gas. They reported respiratory problems, dermatologic symptoms, sleep disturbances, and mood changes with varying frequency. Sixteen reported exacerbations of underlying respiratory disorders, with one temporally related to death. Symptoms led 51 to get medical attention. Nearly all respondents reported that symptoms recurred on re-exposure. We conclude that use of pepper grenades can cause serious acute symptoms in non-combatants accidentally exposed. We recommend alternate methods of riot control - water cannons, baton charges, tasers, plastic or rubber bullets, and so on - that have no collateral side effects on non-combatants be considered for routine use.

Objective: To determine the occurrence of subclinical rickets and its causing factors among adolescent students of schools in Kaghan Valley, Pakistan., Study Design: Observation cross-sectional study., Place and Duration of Study: Department of Biochemistry and Health Sciences, Hazara University, Mansehra, Ayub Medical College and Teaching Hospital, Abbottabad, from March to April 2012., Methodology: Sixty seven students (34 boys and 33 girls) age between 11 - 16 years included in the study from different schools of Kaghan Valley, Pakistan. Characteristic, serum biochemical and nutritional status were measured for all the participants. On the basis of biochemical finding the boys and girls students were divided in to two groups, normal subjects and subclinical rickets (absent symptoms with altered biochemistry)., Results: Twenty six participants, 19 (73%) girls and 07 (27%) boys had biochemical abnormality but no clinical signs and symptoms of rickets. Low vitamin D and high alkaline phosphatase level were observed in 26 (100%), 21 (81%), low calcium in 17 (65%) and low phosphorus 7 (27%) subjects with subclinical rickets. None had high parathormone level above normal range. Nutritional intake of calcium, phosphorus and vitamin D was found less than the recommended daily intake in all the participants., Conclusion: Subclinical rickets is common problem among adolescent students especially in girls which is due to low nutritional intakes and avoidance of sunshine due to environmental and traditional impacts.

Objective: The study on sub clinical rickets is unique in the sense that it has not been preplanned conducted anywhere especially in Pakistan. The objective of present study was to explore the prevalence, gender and geographical distribution of sub clinical rickets and their related factors among school students., Methods: Out of total participants, 189(90%) students were finally included in the study from rural, urban and suburban high schools of Hazara Division, KPK. The age of boys and girls students was 11 years to 16 years. Anthropometrics data along with daily intakes of meal and availability of sun shine was noted on record form. Sub clinical cases were diagnosed with abnormal biochemical findings without physical indications of rickets., Results: Sub clinical rickets was found in 51(27%) students, out of which 15(8%) were boys and 36(19%) girls. Geographically, 26 cases of sub clinical rickets were from rural schools, 16 of urban and 09 found in suburban school. All sub clinical cases had serum level of sunshine vitamin D in between ≥18nmol/l to ≤39 nmol/l, but none of them had parathyroid level increased from upper normal range. Estimated quantities of vitamin D, calcium and phosphorus in daily intakes meal of boy's and girl's student were almost same and found less than recommended amount., Conclusion: Sub clinical rickets is camouflagic rickets among Hazarian school students, especially in girl gender. The major cause contributed to this problem is lack of synergistic effect of Sunshine Vitamin D.

A 16-year-old female presented with a 6-month history of a gradually increasing swelling of the left side of her face. A panoramic radiographic view of the mandible showed diffuse radiolucency in the ramus of the mandible with a loss of cortication on the superior and anterior portion of the condyle. The computed tomography (CT) scan revealed destruction of the mandibular bone and a large retromandibular and inferior temporal fossa mass with areas of breakdown. The biopsy was consistent with tubercular osteomyelitis. Antitubercular therapy resulted in a marked reduction of the size of the swelling over a 9-month period., (Copyright © 2014 Asian-African Society for Mycobacteriology. Published by Elsevier Ltd.

A young woman was admitted with respiratory failure. Prior to her admission, she had been treated for clinical bronchial asthma for about 2 years for recurrent wheezing. Endotracheal intubation was difficult. A fibroptic bronchoscopy, while the patient was ventilated, revealed a central tracheal tumour compromising >90% of the tracheal lumen. The tumour was cored out during rigid bronchoscopy while ventilating the patient through tracheostomy. Histopathology of the tumour was suggestive of adenoid cystic carcinoma.

Background: Previously, Balki determined the Pearson correlation coefficient with the use of ultrasound (US) was 0.85 in morbidly obese parturients. We aimed to determine if the use of the epidural depth equation (EDE) in conjunction with US can provide better clinical correlation in estimating the distance from the skin to the epidural space in morbidly obese parturients., Methods: One hundred sixty morbidly obese (≥40 kg/m(2)) parturients requesting labor epidural analgesia were enrolled. Before epidural catheter placement, EDE was used to estimate depth to the epidural space. This estimation was used to help visualize the epidural space with the transverse and midline longitudinal US views and to measure depth to epidural space. The measured epidural depth was made available to the resident trainee before needle insertion. Actual needle depth (ND) to the epidural space was recorded., Results: Pearson's correlation coefficients comparing actual (ND) versus US estimated depth to the epidural space in the longitudinal median and transverse planes were 0.905 (95% CI: 0.873 to 0.929) and 0.899 (95% CI: 0.865 to 0.925), respectively., Conclusion: Use of the epidural depth equation (EDE) in conjunction with the longitudinal and transverse US views results in better clinical correlation than with the use of US alone.

A young man presented with erythematous rash that appeared 3 days following upper respiratory symptoms and fever. Diffuse exanthematous rash was seen over whole body, most pronounced over the trunk. A subconjunctival haemorrhage also appeared in the left eye following incessant cough. Reverse transcription-PCR of the nasopharyngeal secretions revealed influenza A (2009 pandemic H1N1). The patient responded to oseltamivir therapy. Influenza should be considered in patients presenting with exanthematous skin rash.

Neutral pion transverse momentum spectra were measured in p+C and p+Pb collisions at sqrt[S{NN}]=17.4 GeV at midrapidity (2.3 less than or approximately equal eta{lab} less than or approximately equal 3.0) over the range 0.7 less than or approximately equal p{T} less than or approximately equal 3.5 GeV/c. The spectra are compared to pi{0} spectra measured in Pb+Pb collisions at sqrt[S{NN}]=17.3 GeV in the same experiment. For a wide range of Pb+Pb centralities (N{part} less than or approximately equal 300), the yield of pi{0}'s with p{T} greater than or approximately equal 2 GeV/c is larger than or consistent with the p+C or p+Pb yields scaled with the number of nucleon-nucleon collisions (N{coll}), while for central Pb+Pb collisions with N{part}greater than or approximately equal 350, the pi{0} yield is suppressed.

Two-particle correlations of direct photons were measured in central 208Pb+208Pb collisions at 158A GeV. The invariant interferometric radii were extracted for 100

Three-particle correlations have been measured for identified pi(-) from central 158A GeV Pb+Pb collisions by the WA98 experiment at CERN. A substantial contribution of the genuine three-body correlation has been found as expected for a mainly chaotic and symmetric source.
