Abstract
While the association between low birth weight (LBW; <2500 g) and development of adult chronic renal disease (CKD) is inconsistently reported, less information is available regarding association of high birth weight (HBW; ≥4000 g) with CKD. We undertook a systematic review and meta-analysis on studies published before 30 September 2015 and report associations between birth weight and renal function. Blood (glomerular filtration rate (GFR)) and urine (microalbuminuria/albumin excreation rate (AER)/urinary albumin creatinine ratio (ACR)) parameters were used to define CKD. Three different effect size estimates were used (odds ratio, regression coefficient and mean difference). The odds of developing CKD in the life course among those born LBW was 1.77 (95% CI: 1.42, 2.20) times and 1.68 (1.27, 2.33) times, assessed by blood and urine parameters respectively. Higher risk was also observed among Asian and Australian populations (blood: OR 2.68; urine: OR 2.28), individuals aged ≤30 years (blood: OR 2.30; urine: OR 1.26), and ≥50 years (blood: OR 3.66; urine: OR 3.10), people with diabetes (blood: OR 2.51), and aborigines (urine: OR 2.32). There was no significant association between HBW and CKD. For every 1 kg increase in BW, the estimated GFR increased by 2.09 mL/min per 1.73 m(2) (1.33-2.85), and it was negatively associated with LogACR (ß -0.07, 95% CI: -0.14, 0.00). LBW inborn had lower mean GFR -4.62 (-7.10, -2.14) compared with normal BW. Findings of this study suggest that LBW increased the risk of developing CKD, and HBW did not show any significant impact.

Abstract
Evidences on diagnosis of tuberculosis (TB) following the World Health Organization (WHO) criteria in children with severe acute malnutrition (SAM) are lacking. We sought to evaluate the WHO criteria for the diagnosis of TB in such children. In this prospective study, we enrolled SAM children aged <5 with radiological pneumonia. We collected induced sputum and gastric lavage for smear microscopy, mycobacterial culture, and Xpert MTB/RIF. Using the last 2 methods as the gold standard, we determined sensitivity, specificity, and positive and negative predictive values of WHO criteria (n = 388). However, Xpert MTB/RIF was performed on the last 214 children. Compared to mycobacterial culture-confirmed TB, sensitivity and specificity (95% confidence interval) of WHO criteria were 40 (14% to 73%) and 84 (80% to 87%), respectively. Compared to culture- and/or Xpert MTB/RIF-confirmed TB, the values were 22% (9% to 43%) and 83 (79% to 87%), respectively. Thus, the good specificity of the WHO criteria may help minimize overtreatment with anti-TB therapy in SAM children, especially in resource-limited settings.

Abstract
AIM To establish a predictive nomogram for high-grade prostate cancer (HGPCa) in biopsy-naive patients based on the Prostate Imaging-Reporting and Data System version 2 (PI-RADS v2), magnetic resonance imaging (MRI)-based prostate volume (PV), MRI-based PV-adjusted prostate-specific antigen density (PSAD), and other classical parameters. MATERIAL AND METHODS Between August 2014 and August 2015, 158 men who were eligible for analysis were included as the training cohort. A prediction model for HGPCa was built using backward logistic regression and was presented on a nomogram. The prediction model was evaluated by a validation cohort between September 2015 and March 2016 (n=89). Histology of all lesions was obtained with MRI-directed transrectal ultrasound (TRUS)-guided targeted and sectoral biopsy. RESULTS The multivariate analysis revealed that patient age, PI-RADS v2 score, and adjusted PSAD were independent predictors for HGPCa. The most discriminative cut-off value for the logistic regression model was 0.33; the sensitivity, specificity, positive predictive value, and negative predictive value were 83.3%, 87.4%, 88.4%, and 81.2%, respectively. The diagnostic performance measures retained similar values in the validation cohort (AUC=0.83). CONCLUSION The nomogram for forecasting HGPCa is effective and potentially reducing harm from unnecessary prostate biopsy and over-diagnosis.

Abstract
A total of 60 animals (38 cows, 22 heifers) were selected and were divided into three groups of 20 animals each (containing both anoestrus and repeat breeder) in which treatment was performed for 60 days. Group I: control (farmer practice), T1 group: group I + hormone (double synch), and T2 group: group I + hormone (Estra double synch). The growth performances were measured in terms of body weight and average daily gain (ADG). Blood collection was done at the start and end of the experiment for assessment of blood biochemical, hematological, and reproductive status of the animals. Results revealed significant improvement in growth and reproductive performances in treatment group as compared to control group. Higher percentage of conception was achieved in group III (60%) followed by group II (55%). The least percentage was in group I (15%), i.e., in control group. So it was found that the effect of treating the reproductive-disordered animals with Estra double synch gave comparatively better result than double synch hormonal application.

Abstract
AIM This study was conducted to find out the seroprevalence of Rotavirus(RV) infection among the pig population of Arunachal Pradesh. MATERIALS AND METHODS Serums samples were collected from piglets of age ranging from 1 week to 6 months and the sows associated with the piglets that were reared under organized and unorganized system of management in six different districts of Arunachal Pradesh. The prevalence of RV specific antibodies was detected using a polyclonal antibody-based indirect enzyme-linked immunosorbent assay (i-ELISA). RESULTS The study revealed that out of 394 serum samples, 255 (64.72%) samples were found to be positive for RV-specific antibody in i-ELISA. Considering the samples from different districts, Papumpare district of Arunachal Pradesh showed highest numbers of seropositive animals (68.75%) followed by upper Subansiri (64.91%) while West Siang district showed lowest positivity rate (61.22%). CONCLUSION As considerable seropositivity was recorded among pig population of Arunachal Pradesh in this study, there is urgent need to establish high-impact and cost-effective public health intervention tools, key among them being the introduction of strict hygiene practice and RV vaccination program, to greatly reduce the number of deaths due to diarrheal diseases. To the authors' knowledge, this is the first report on the prevalence of RV infection from pigs of Arunachal Pradesh.

Abstract
To our knowledge, there are no data on the role of overweight and obesity in childhood pneumonia. We sought to determine that impact of overweight and obesity in such children. In this retrospective chart analysis, we enrolled hospitalized children aged 6 to 59 months in the Dhaka Hospital of the icddr,b, Bangladesh (International Centre for Diarrhoeal Disease Research, Bangladesh), from January 2010 to June 2014. Children with pneumonia having overweight and obesity (body mass index Z score [BMIZ] >2.00) constituted cases (n = 25), and those who had pneumonia without overweight and obesity (BMIZ -2.00 to 2.00) constituted controls (n = 75). Controls were 3-fold of the cases and were randomly selected. Demographic, clinical, and laboratory data of the cases and the controls were compared. The cases more often had diarrhea and dehydration (36% vs 12%, P = .013), hypoxemia (SpO2 < 90% in room air; 28% vs 7%, P = .009) on admission, and required to change antibiotics (32% vs 11%, P = .023) during hospitalization compared to the controls. However, in logistic regression analysis the cases were independently associated with diarrhea (P < .001) and hypoxemia (P = .024) on admission. Our data suggest that overweight and obesity in children with pneumonia is prone to be associated with hypoxemia on admission, which may guide clinicians in promptly managing pneumonia in order to evade its ramification in such children. However, future research with larger samples is imperative to consolidate or refute our observation.

Abstract
Breast tuberculosis (TB) is rare form of extra-pulmonary TB. It is most commonly seen in women of reproductive age group, especially in young, multiparous women who are breast feeding. In geriatric women, breast TB in some cases simulates with breast carcinoma due to common signs which include hard breast lump with nodular surface, ulceration, fixity to skin, discharging sinus, retraction of nipple, axillary lymphadenopathy etc. Hence, it is very difficult to differentiate breast TB from breast cancer, especially in elderly women on clinical ground only, and therefore, histopathological diagnosis is mandatory. Fine needle aspiration cytology is frequently inconclusive due to very small amount of tissue material, and open biopsy or lumpectomy followed by histopathological examination is necessary to confirm the diagnosis of breast TB. Six-month course of anti-tuberculous therapy - ATT (rifampicin, isoniazid, pyrazinamide and ethambutol) is adequate for complete resolution. Here, we report a case of breast TB in an elderly women presenting with left sided breast lump with ulceration of overlying skin and ipsilateral axillary lymphadenopathy. This case of tuberculous mastitis was suspected to be carcinoma due to presence of hard, tender, breast lump with irregular margin, nodular surface, ulceration, purulent discharge and ipsilateral axillary lymphadenopathy in absence of any constitutional symptoms of TB, and heterogenous, hypoechoic mass on USG, which was confirmed by histopathological examination of resected breast lump and responded fully to ATT.

Abstract
Metastasis is the complex process by which primary tumor cells migrate and establish secondary tumors in an adjacent or distant location in the body. Early detection of metastatic disease and effective therapeutic options for targeting these detected metastases remain impediments to effectively treating patients with advanced cancers. If metastatic lesions are identified early, patients might maximally benefit from effective early therapeutic interventions. Further, monitoring patients whose primary tumors are effectively treated for potential metastatic disease onset is also highly valuable. Finally, patients with metastatic disease can be monitored for efficacy of specific therapeutic interventions through effective metastatic detection techniques. Thus, being able to detect and visualize metastatic lesions is key and provides potential to greatly improve overall patient outcomes. In order to achieve these objectives, researchers have endeavored to mechanistically define the steps involved in the metastatic process as well as ways to effectively detect metastatic progression. We presently overview various preclinical and clinical in vitro and in vivo assays developed to more efficiently detect tumor metastases, which provides the foundation for developing more effective therapies for this invariably fatal component of the cancerous process.

Abstract
Objectives: To determine the incidence of common peroneal nerve (CPN) injury following short saphenous vein surgery (SSV) in a UK district general hospital, and establish possible risk factors, and preventative strategies to minimize the risk of nerve injury following this type of surgery. Methods: Retrospective review of all cases of SSV surgery performed in a single institution during the period January 2002–October 2004. Results: Sixty-four patients underwent SSV surgery during the review period. Three patients (4.7%) developed a CPN injury postoperatively. One patient recovered fully after 24 h, whereas the other two patients' symptoms recovered within six months. All three patients had a saphenopopliteal junction (SPJ) located high above the popliteal skin crease. Conclusions: CPN injury during SSV surgery occurs with an appreciable frequency. In view of this, there is a need for a revised approach to the management of SSV disease, possibly incorporating less-invasive techniques such as endovenous closure.

Abstract
Since its original discovery in 2002, AEG-1/MTDH/LYRIC has emerged as a primary regulator of several diseases including cancer, inflammatory diseases, and neurodegenerative diseases. AEG-1/MTDH/LYRIC has emerged as a key contributory molecule in almost every aspect of cancer progression, including uncontrolled cell growth, evasion of apoptosis, increased cell migration and invasion, angiogenesis, chemoresistance, and metastasis. Additionally, recent studies highlight a seminal role of AEG-1/MTDH/LYRIC in neurodegenerative diseases and obesity. By interacting with multiple protein partners, AEG-1/MTDH/LYRIC plays multifaceted roles in the pathogenesis of a wide variety of diseases. This review discusses the current state of understanding of AEG-1/MTDH/LYRIC regulation and function in cancer and other diseases with a focus on its association/interaction with several pivotal protein partners.

Abstract
Background Although Streptococcal bacteremia is common in diarrheal children with high morbidity and mortality, no systematic data are available on Streptococcal bacteremia in diarrheal children. We sought to evaluate the factors associated with Streptococcal bacteremia in diarrheal children under five years of age and their outcome. Methods We used an unmatched case-control design to investigate the associated factors with Streptococcal bacteremia in all the diarrheal children under five years of age through electronic medical record system of Dhaka hospital of International Centre for Diarrhoeal Disease Research, Bangladesh. We had simultaneously used a retrospective cohort design to further evaluate the outcome of our study children. All the enrolled children had their blood culture done between January 2010 and December 2012. Comparison was made among the children with (cases = 26) and without Streptococcal bacteremia (controls = 78). Controls were selected randomly from hospitalized diarrheal children under five years of age. Results Cases had proportionately higher deaths compared to controls, but it was statistically insignificant (15% vs. 10%, p = 0.49). The cases more often presented with severe dehydration, fever, respiratory distress, severe sepsis, and abnormal mental status compared to the controls (for all p<0.05). In the logistic regression analysis, after adjusting for potential confounders, it has been found that Streptococcal bacteremia in diarrheal children under five years of age was independently associated with nutritional edema (OR: 5.86, 95% CI = 1.28–26.80), hypoxemia (OR: 19.39, 95% CI = 2.14–175.91), fever (OR: 4.44, 95% CI = 1.13–17.42), delayed capillary refill time (OR: 7.00, 95% CI = 1.36–35.93), and respiratory distress (OR: 2.69, 95% CI = 1.02–7.12). Conclusions and Significance The results of our analyses suggest that diarrheal children under five years of age presenting with nutritional edema, hypoxemia, fever, delayed capillary refill time, and respiratory distress may be at risk of Streptococcal bacteremia. It underscores the importance of identification of these simple clinical parameters for the prompt recognition and management in order to reduce the morbidity and death of such children especially in resource limited settings.

Abstract
BACKGROUND Diarrheal disease is the second leading cause of disease in children less than 5 y of age. Poor water, sanitation, and hygiene conditions are the primary routes of exposure and infection. Sanitation and hygiene interventions are estimated to generate a 36% and 48% reduction in diarrheal risk in young children, respectively. Little is known about whether the number of households sharing a sanitation facility affects a child's risk of diarrhea. The objective of this study was to describe sanitation and hygiene access across the Global Enteric Multicenter Study (GEMS) sites in Africa and South Asia and to assess sanitation and hygiene exposures, including shared sanitation access, as risk factors for moderate-to-severe diarrhea (MSD) in children less than 5 y of age. METHODS/FINDINGS The GEMS matched case-control study was conducted between December 1, 2007, and March 3, 2011, at seven sites in Basse, The Gambia; Nyanza Province, Kenya; Bamako, Mali; Manhiça, Mozambique; Mirzapur, Bangladesh; Kolkata, India; and Karachi, Pakistan. Data was collected for 8,592 case children aged <5 y old experiencing MSD and for 12,390 asymptomatic age, gender, and neighborhood-matched controls. An MSD case was defined as a child with a diarrheal illness <7 d duration comprising ≥3 loose stools in 24 h and ≥1 of the following: sunken eyes, skin tenting, dysentery, intravenous (IV) rehydration, or hospitalization. Site-specific conditional logistic regression models were used to explore the association between sanitation and hygiene exposures and MSD. Most households at six sites (>93%) had access to a sanitation facility, while 70% of households in rural Kenya had access to a facility. Practicing open defecation was a risk factor for MSD in children <5 y old in Kenya. Sharing sanitation facilities with 1-2 or ≥3 other households was a statistically significant risk factor for MSD in Kenya, Mali, Mozambique, and Pakistan. Among those with a designated handwashing area near the home, soap or ash were more frequently observed at control households and were significantly protective against MSD in Mozambique and India. CONCLUSIONS This study suggests that sharing a sanitation facility with just one to two other households can increase the risk of MSD in young children, compared to using a private facility. Interventions aimed at increasing access to private household sanitation facilities may reduce the burden of MSD in children. These findings support the current World Health Organization/ United Nations Children's Emergency Fund (UNICEF) system that categorizes shared sanitation as unimproved.

Abstract
Pulmonary involvement by Aspergillus sp. mainly includes allergic bronchopulmonary aspergillosis, aspergilloma, and invasive aspergillosis. Aspergilloma (Fungal ball) is the most common form of aspergillous pulmonary involvement, which occurs in preexisting pulmonary cavities, especially secondary to pulmonary tuberculosis. Ankylosing spondylitis is a rare cause of upper lobe fibro-cavitary lesions in pulmonary parenchyma. It may also lead to development of fungal balls in pulmonary cavities. Most common presentation is mild to massive hemoptysis; dyspnoea, chronic cough, expectoration may be other presentation; even the patient may remain asymptomatic. Intaracavitary mobile mass is a valuable sign for fungal ball, best detected by computed tomography (CT) scan of thorax. Lobectomy is the treatment of choice to stop the hemoptysis, if the general condition of the patient is fit; otherwise associated co-morbidities complicate the post-operative scenario. In this situation, bronchial artery embolization may be used as a temporary measure to control hemoptysis. Here, we report a case of bilateral aspergillomas within the cavities located in upper lobes of both lungs in a 74 years old male who was suffering from ankylosing spondylitis for last 42 years.

Abstract
Adherence of an embryo to the uterus represents the most critical step of the reproductive process. Implantation is a synchronized event between the blastocyst and the uterine luminal epithelium, leading to structural and functional changes for further embryonic growth and development. The milieu comprising the complex process of implantation is mediated by estrogen through diverse but interdependent signaling pathways. Mouse models have demonstrated the relevance of the expression of estrogen-modulated paracrine factors to uterine receptivity and implantation window. More importantly, some factors seem to serve as molecular links between different estrogen pathways, promoting cell growth, acting as molecular chaperones, or amplifying estrogenic effects. Abnormal expression of these factors can lead to implantation failure and infertility. This review provides an overview of several well-characterized signaling pathways that elucidates the molecular cross talk involved in the uterus during early pregnancy.

Abstract
We aimed to evaluate the factors associated with nosocomial infections (NIs) in under-5 children and in bacterial isolates from their blood, urine, and stool. We reviewed all under-5 hospitalized children with clinically diagnosed NIs in the inpatient ward at Dhaka Hospital of International Centre for Diarrhoeal Disease Research, Bangladesh, between January and December 2012. Comparison was made among the children with (cases = 71) and without NI (controls = 142). NI was defined as the development of new infection 48 hours after admission. Bacterial isolates in urine, blood, and stool were found in 11/52 (21%), 9/69 (13%), and 2/16 (12%) respectively. In logistic regression analysis, the children with NI were independently associated with severe acute malnutrition, congenital anomaly, invasive diarrhea, urinary tract infection on admission, and use of intravenous cannula during hospitalization. Thus, identification of these simple clinical parameters may help in preventive measures being taken to reduce the rate of NIs in such children.

Abstract
Bullous pemphigoid is a chronic, autoimmune, acquired subepidermal blistering disorder. It is idiopathic in origin, and mainly seen in elderly individuals. Association between bullous pemphigoid and internal malignancies is reported in the literature, but the exact causal relation is not established. Paraneoplastic bullous pemphigoid is rarely reported in lung cancers, especially in squamous cell variety. So their presence should raise the suspicion of various internal malignancies including lung cancer. It is presented mainly with tense, large blisters over the erythematous base or over normal skin. Subepidermal blisters with tissue eosinophilia are characteristic histopathological features of bullous pemphigoid. Direct immunofluorescence shows linear deposits of IgG - complement complex along the dermoepidermal junction. Conventional treatment of bullous pemphigoid along with treatment of lung cancer (surgery, chemotherapy, radiotherapy) may result in successful resolution of skin lesions. Here, we report a rare association of paraneoplastic bullous phemphigoid and squamous cell carcinoma of lung in a 76-year-old male to increase the awareness among the clinicians regarding this variety of cutaneous paraneoplastic manifestation of lung cancer.

Abstract
This study evaluated the effect of different flours on the physicochemical, textural, and sensory properties of chicken patties. pH; cooking yield %; water holding capacity (WHC); proximate analysis (cooked); cholesterol content; and storage stability studies of control (Con) and sorghum flour (SF; 10%w/w), finger millet flour (FMF; 10%w/w), and carrageenan (Cgn; 0.5% w/w) treated chicken patties were observed in this study. Texture profile analysis (TPA) parameters like hardness, springiness, cohesiveness, gumminess, chewiness, and sensory parameters were estimated on cooked patties. Highly significant (P < 0.01) difference in fat %, total ash %, and cholesterol content; significant (P < 0.05) difference in moisture % (cooked); and no significant (P > 0.05) difference in pH, WHC, and protein % among control and treatments were noticed. Storage stability was dependent on treatments and storage periods. Significant difference (P < 0.05) was observed in different TPA parameters among the treatments, except for hardness value. Sensory scores showed no significant difference (P > 0.05) between Con and treatments.

Abstract
Background Appropriate intervention is critical in reducing deaths among under-five, severe acutely malnourished (SAM) children with danger signs of severe pneumonia; however, there is paucity of data on outcome of World Health Organisation (WHO) recommended interventions of SAM children with severe pneumonia. We sought to evaluate outcome of the interventions in such children. Methods We prospectively enrolled SAM children aged 0–59 months, admitted to the Intensive Care Unit (ICU) or Acute Respiratory Infection (ARI) ward of the Dhaka Hospital of the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b), between April 2011 and June 2012 with cough or respiratory difficulty and radiological pneumonia. All the enrolled children were treated with ampicillin and gentamicin, and micronutrients as recommended by the WHO. Comparison was made among pneumonic children with (n = 111) and without WHO defined danger signs of severe pneumonia (n = 296). The outcomes of interest were treatment failure (if a child required changing of antibiotics) and deaths during hospitalization. Further comparison was also made among those who developed treatment failure and who did not and among the survivors and deaths. Results SAM children with danger signs of severe pneumonia more often experienced treatment failure (58% vs. 20%; p<0.001) and fatal outcome (21% vs. 4%; p<0.001) compared to those without danger signs. Only 6/111 (5.4%) SAM children with danger signs of severe pneumonia and 12/296 (4.0%) without danger signs had bacterial isolates from blood. In log-linear binomial regression analysis, after adjusting for potential confounders, danger signs of severe pneumonia, dehydration, hypocalcaemia, and bacteraemia were independently associated both with treatment failure and deaths in SAM children presenting with cough or respiratory difficulty and radiological pneumonia (p<0.01). Conclusion and Significance The result suggests that SAM children with cough or respiratory difficulty and radiologic pneumonia who had WHO-defined danger signs of severe pneumonia more often had treatment failure and fatal outcome compared to those without the danger signs. In addition to danger signs of severe pneumonia, other common causes of both treatment failure and deaths were dehydration, hypocalcaemia, and bacteraemia on admission. The result underscores the importance for further research especially a randomized, controlled clinical trial to validate standard WHO therapy in SAM children with pneumonia especially with danger signs of severe pneumonia to reduce treatment failures and deaths.

Abstract
BACKGROUND In developing countries, there is no published report on predicting factors of severe sepsis in severely acute malnourished (SAM) children having pneumonia and impact of fluid resuscitation in such children. Thus, we aimed to identify predicting factors for severe sepsis and assess the outcome of fluid resuscitation of such children. METHODS In this retrospective case-control study SAM children aged 0-59 months, admitted to the Intensive Care Unit (ICU) of the Dhaka Hospital of the International Centre for Diarrhoeal Disease Research, Bangladesh from April 2011 through July 2012 with history of cough or difficult breathing and radiologic pneumonia, who were assessed for severe sepsis at admission constituted the study population. We compared the pneumonic SAM children with severe sepsis (cases = 50) with those without severe sepsis (controls = 354). Severe sepsis was defined with objective clinical criteria and managed with fluid resuscitation, in addition to antibiotic and other supportive therapy, following the standard hospital guideline, which is very similar to the WHO guideline. RESULTS The case-fatality-rate was significantly higher among the cases than the controls (40% vs. 4%; p<0.001). In logistic regression analysis after adjusting for potential confounders, lack of BCG vaccination, drowsiness, abdominal distension, acute kidney injury, and metabolic acidosis at admission remained as independent predicting factors for severe sepsis in pneumonic SAM children (p<0.05 for all comparisons). CONCLUSION AND SIGNIFICANCE We noted a much higher case fatality among under-five SAM children with pneumonia and severe sepsis who required fluid resuscitation in addition to standard antibiotic and other supportive therapy compared to those without severe sepsis. Independent risk factors and outcome of the management of severe sepsis in our study children highlight the importance for defining optimal fluid resuscitation therapy aiming at reducing the case fatality in such children.

Abstract
Molecular identification of the invasion plasmid antigen-H (ipaH) gene has been established as a useful detection mechanism for Shigella spp. The Global Enteric Multicenter Study (GEMS) identified the etiology and burden of moderate-to-severe diarrhea (MSD) in sub-Saharan Africa and south Asia using a case-control study and traditional culture techniques. Here, we used quantitative polymerase chain reaction (qPCR) to identify Shigella spp. in 2,611 stool specimens from GEMS and compared these results to those using culture. Demographic and nutritional characteristics were assessed as possible risk factors. The qPCR identified more cases of shigellosis than culture; however, the distribution of demographic characteristics was similar by both methods. In regression models adjusting for Shigella quantity, age, and site, children who were exclusively breast-fed had significantly lower odds of MSD compared with children who were not breast-fed (odds ratio [OR] = 0.47, 95% confidence interval (CI) = 0.28-0.81). The association between Shigella quantity and MSD increased with age, with a peak in children of 24-35 months of age (OR = 8.2, 95% CI = 4.3-15.7) and the relationship between Shigella quantity and disease was greatest in Bangladesh (OR = 13.2, 95% CI = 7.3-23.8). This study found that qPCR identified more cases of Shigella and age, site, and breast-feeding status were significant risk factors for MSD.

Abstract
BACKGROUND Although cigarette smoking affects all biological systems of the human body including the gastrointestinal tract, there is a lack of evidence regarding its effect on the severity of diarrhoeal disease and whether a dose-response relationship exists. We therefore tested for the presence of specific causative pathogens for infectious diarrhoea, assessed the independent effect of smoking on its severity and tested whether any dose-response relationship existed while controlling for subjects' age, sociodemographic characteristics and presence of causative pathogens in an urban setting in Bangladesh. METHODS A total of 20,757 patients aged 15 years and above with diarrhoea were enrolled into the Diarrhoeal Disease Surveillance System, managed by the International Centre for Diarrhoeal Disease Research, Bangladesh, from 1993 to 2012. We collected data on individuals' current daily consumption of cigarettes and bidis (traditional hand-rolled cigarettes) and conducted an ordered logistic regression to determine the effect of smoking on diarrhoeal disease severity and whether a dose-response relationship exists. RESULTS We identified 19 % of patients with diarrhoea as smokers, of whom 52 % smoked 1-9 cigarettes per day. While 97 % of smokers were male, 41 % were aged 15-30 years of age. Smokers were found to have a significantly lower severity of diarrhoeal disease (OR: 0.92, 95 % CI: 0.85-0.99, p = 0.025) after adjusting for age, wealth quintile, illiteracy and the presence of specific causative pathogens (Vibrio cholerae and Shigella). We observed no dose-response relationship between the number of cigarettes smoked per day and disease severity when adjusting for the same covariates. Smokers were more frequently infected with Shigella (7 vs. 6 %, p < 0.001) and less often with Vibrio cholerae (22 vs. 26 %, p < 0.001) than their non-smoking counterparts. CONCLUSIONS The aetiology and severity of diarrhoeal disease differed between smokers and non-smokers in our sample. However, we found no dose-response relationship between disease severity and the number of cigarettes smoked per day.

Abstract
We aimed to evaluate sociodemographic, epidemiological, and clinical risk factors for pulmonary tuberculosis (PTB) in children presenting with severe acute malnutrition (SAM) and pneumonia. Children aged 0 to 59 months with SAM and radiologic pneumonia from April 2011 to July 2012 were studied in Bangladesh. Children with confirmed PTB (by culture and/or X-pert MTB/RIF) (cases = 27) and without PTB (controls = 81; randomly selected from 378 children) were compared. The cases more often had the history of contact with active PTB patient (P < .01) and exposure to cigarette smoke (P = .04) compared with the controls. In logistic regression analysis, after adjusting for potential confounders, the cases were independently associated with working mother (P = .05) and positive tuberculin skin test (TST; P = .02). Thus, pneumonia in SAM children is a common presentation of PTB and further highlights the importance of the use of simple TST and/or history of contact with active TB patients in diagnosing PTB in such children, especially in resource-limited settings.

Abstract
Background and Aims: Data on Bacterial isolates from tracheal aspirates in children with severe pneumonia requiring intubation and mechanical ventilation especially in developing countries are very limited. We examined the microbial spectrum of bacteria isolated from tracheal aspirate of those children. The antibiotic susceptibility profiles of those bacteria were also examined.Methods: We evaluated the data of all mechanically ventilated children aged 0-59 months admitted to Intensive Care Unit (ICU) of Dhaka Hospital of the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b) between August 2009 and July 2013 having their tracheal aspirate culture done. Data were extracted from electronic medical records of the Dhaka Hospital.Results: Among 836 admitted pneumonia children in the ICU, we identified 35 children who fulfilled the inclusion criteria. Among them 34 (97%) had positive bacterial growths: Klebseilla species in 14 (40%), Escherichia coli in 11 (31%), Acinetobacter in 8 (23%) and Streptococcus species in 8 (23%). Additionally, Enterococcus, Staphylococcus aureus, Pseudominas and Proteus species were identified in 6 (17%), 4 (11%), and 2 (6%) of the children respectively. The susceptibility of the gram-negatives, except Klebseilla, to ampicillin, cotrimoxazole, gentamycin, ciprofloxacin, azithromycin, and ceftriaxone ranged from 0- 54%, while that for ceftazidime and amikacin ranged from 12-80%. The sensitivity of Klebseilla to these antibiotics ranged from 0-100%.Conclusions: Our data suggests that gram-negative bacteria, Klebseilla followed by Escherichia coli, and Acenetobacter are the predominant bacteria associated with severe pneumonia in ventilated children. The increased number of infections caused by Gram-negative bacteria is being accompanied by rising rates of multi-drug resistance which underscores the importance of aggressive antimicrobial therapy in the management of such children.Bangladesh Crit Care J September 2014; 2 (2): 60-64

Abstract
Introduction Hypernatremia (serum sodium ≥150mmol/L) is one of the most life-threatening complications of childhood diarrhea, and its management remains challenging, even in a highly advanced critical care setting. This case report describes the acute clinical course and 3-month neurological follow-up after discharge of an infant with extreme hypernatremia in an intensive care unit in Dhaka, Bangladesh. Case presentation A 6-month-old Asian Bangladeshi girl of middle-class socioeconomic status was admitted to the intensive care unit of our institution in 2012 with acute watery diarrhea, lethargy and hypernatremia (208mmol/L serum sodium). She had a history of taking excess oral rehydration salt: five packets each, inappropriately prepared, rice-based, properly diluted, glucose-based oral rehydration salt. Her hypernatremia was treated exclusively with oral rehydration salt solution. She experienced seizures on the third day of her hospitalization and was treated with anticonvulsant drugs. Later in the course of her hospitalization, Enterobacter spp bacteremia was detected and successfully treated with ciprofloxacin. Although magnetic resonance imaging of her brain at discharge showed cerebral edema, brain magnetic resonance imaging appeared normal at a follow-up examination 3 months after discharge. Electroencephalograms taken at discharge and at her 3-month follow-up examination also appeared normal. Conclusions Successful management of extreme hypernatremia with only oral rehydration salt did not result in observable neurological consequences, which emphasizes the importance of the use of oral rehydration salt for the clinical management of childhood hypernatremia.
