A comparison of the quality of images of chest X-ray between handheld portable digital X-ray & routinely used digital X-ray machine

Background & objectives: Chest X-ray (CXR) is an important screening tool for pulmonary tuberculosis (TB). Accessibility to CXR facilities in difficult-to-reach and underserved populations is a challenge. This can potentially be overcome by deploying digital X-ray machines that are portable. However, these portable X-ray machines need to be validated before their deployment in the field. Here, we compare the image quality of CXR taken by a newly developed handheld X-ray machine with routinely used reference digital X-ray machine through the conduct of a feasibility study. Methods: A total of 100 participants with suspected pulmonary TB were recruited from the outpatient departments of a medical college and a community health centre in Agra. Each participant underwent CXR twice, once with each machine. Both sets of de-identified images were independently read by two radiologists, who were blinded to the type of X-ray machine used. The primary outcome was agreement between image qualities produced by these two machines. Results: The intra-observer (radiologist) agreements regarding the status of the 15 CXR parameters ranged between 74 per cent and 100 per cent, with an unweighted mean of 87.2 per cent (95% confidence interval: 71.5-100). The median Cohen’s kappa values for intra-observer agreement were 0.62 and 0.67 for radiologists 1 and 2, respectively. In addition, on comparison of the overall median score of quality of the image, the handheld machine images had a higher score for image quality. Interpretation & conclusions: The current study shows that a handheld X-ray machine, which is easy to use and can potentially be carried to any area, produces X-ray images with quality that is comparable to digital X-ray machines routinely used in health facilities.

Study of resveratrol against bone loss by using in-silico and in-vitro methods / Estudo do resveratrol contra a perda óssea usando métodos in silico e in vitro

By applying the in-silico method, resveratrol was docked on those proteins which are responsible for bone loss. The Molecular docking data between the resveratrol and Receptor activator of nuclear factor-kappa-Β ligand [RANKL] receptors proved that resveratrol binds tightly to the receptors, showed the highest binding affinities of −6.9, −7.6, −7.1, −6.9, −6.7, and −7.1 kcal/mol. According to in-vitro data, Resveratrol reduced the osteoclasts after treating Marrow-Derived Macrophages [BMM] with Macrophage colony-stimulating factor [MCSF] 20ng / ml and RANKL 50ng / ml, with different concentrations of resveratrol (2.5, 10 μg / ml) For 7 days, the cells were treated with MCSF (20 ng / ml) and RANKL (40 ng / ml) together with concentrated trimethyl ether and resveratrol (2.5, 10 μg / ml) within 12 hours. Which, not affect cell survival. After fixing osteoclast cells with formaldehyde fixative on glass coverslip followed by incubation with 0.1% Triton X-100 in PBS for 5 min and after that stain with rhodamine phalloidin staining for actin and Hoechst for nuclei. Fluorescence microscopy was performed to see the distribution of filaments actin [F.actin]. Finally, resveratrol reduced the actin ring formation. Resveratrol is the best bioactive compound for drug preparation against bone loss.

Com a aplicação do método in-silico, o resveratrol foi ancorado nas proteínas responsáveis pela perda óssea. Os dados de docking molecular entre o resveratrol e o ligante do receptor ativador do fator nuclear kappa-Β [Receptor Activator of Nuclear Factor kappa-B Ligant (RANKL)] provaram que o resveratrol se liga fortemente aos receptores, mostraram as afinidades de ligação mais altas de −6,9, −7,6, −7,1, −6,9, - 6,7 e -7,1 kcal / mol. De acordo com dados in-vitro, o resveratrol reduziu os osteoclastos após o tratamento de macrófagos derivados da medula óssea [Bone Marrow derived Macrophage (BMM)] com fator estimulador de colônias de macrófagos [Macrophage Colony-Stimulating Factor (MCSF)] 20ng / ml e RANKL 50ng / ml, com diferentes concentrações de resveratrol (2,5, 10 μg / ml). Durante sete dias, as células foram tratadas com MCSF (20 ng / ml) e RANKL (40 ng / ml) juntamente com éter trimetílico concentrado e resveratrol (2,5, 10 μg / ml) em 12 horas, processo que não afeta a sobrevivência celular. Após a fixação de células de osteoclastos com fixador de formaldeído em lamela de vidro seguido de incubação com 0,1% Triton X-100 em PBS por 5 min, foi realizado posteriormente o procedimento para corar com rodamina faloidina a actina e Hoechst os núcleos. A microscopia de fluorescência foi realizada para ver a distribuição dos filamentos de actina [F.actina]. Finalmente, o resveratrol reduziu a formação do anel de actina. O resveratrol é o melhor composto bioativo para o preparo de medicamentos contra a perda óssea.

Assessing engagement of scheduled tribe communities in the functioning of Village Health Sanitation & Nutrition Committees in India

India is home to the largest population of indigenous tribes in the world. Despite initiative of the National Rural Health Mission, now National Health Mission (NHM) and various tribal development programmes since India’s Independence, disparity in healthcare for Scheduled Tribes (STs) prevails. The constitution of Village Health Sanitation and Nutrition Committees (VHSNCs) in 2007 by the NHM is a step towards decentralized planning and community engagement to improve health, nutrition and sanitation services. VHSNCs are now present in almost all States of the country. However, several reports including the 12th Common Review Mission report have highlighted that these committees are not uniformly following guidelines and lack clarity about their mandates, with no clear visibility of their functioning in tribal areas. Therefore, this review was conducted to assess the participation of the VHSNCs in tribal dominated States in order to know in detail about their functioning and gaps if any that require intervention. Several deviations from the existing guidelines of NHM were identified and we concluded that in order to sustain and perform well, VHSNCs not only require, mobilization and strict monitoring but also motivation and willingness of its members to bring in a radical change at the grassroot level. With continuous supervision and support from both the Government and various non- governmental organizations, handholding, strategic deployment of workforce, community participation and sustained financial support, VHSNCs would be able to facilitate delivery of better healthcare to the indigenous population

Impact of alien fishes on the distribution pattern of indigenous freshwater fishes of Punjab, Pakistan / Impacto de peixes invasores no padrão de distribuição de peixes de água doce em Punjab, Paquistão

Pakistan is the country with mega freshwater fish diversity of native and alien species. In the presence of enormous native fishes varies species of exotic fishes have been introduced into the freshwater bodies of Pakistan which are competing with native freshwater fish fauna and making them deprive of food and habitat as well. Intentional or accidental introductions of animals, plants and pathogens away from their native niche is considered as major leading problem for biodiversity of invaded habitat. Three years study (from January 2017 to December 2019) was conducted in freshwater bodies of Province Punjab, Pakistan. Study was designed to know exotic species impacts on the distribution of native species of fishes. During current survey a total of 68 (indigenous and exotic) fish species belonging to 14 families were recorded from head Qadirabad, head Baloki, Islam headworks and Rasul barrage. Statistical analysis showed that Shannon-Wiener diversity index was the highest (1.41) at both Rasul barrage and Islam headworks but, invasive species were present in very less number in these study sites i.e. Oreochromis mozambicus, O. niloticus, Hypophthalmichthys nobilis, Carassius auratus, Ctenophryngdon idella, Cyprinus carpio and H. molitrix. The diversity index showed that comparatively low diversity was present in both area head Qadirabad (1.30) and head Baloki (1.4) due to high pressure of invasive species. Direct observation of species and statistical analysis showed that aliens’ species produced negative impact on the local fish fauna diversity, evenness, and numbers. It is concluded that many factors are impacts on the diversity of native fishes, but alien (invasive) species also play a major role to reduction of native species, because aliens’ species produce competition for native species. So it is urgent need to analysis the aliens and native food web and roosting sites in Pakistan, in future.

A Comparative Study of Oral Ivermectin and Topical 5% Permethirn Cream in the Treatment of Scabies in Patient Suffering from Diabetes Mellitus.

Scabies is one of the commonest diseases among all age groups. Topical permethrin is a widely used treatment option for scabies. Ivermectin is a newer oral agent for the treatment of scabies. This study was done to compare the efficacy of permithrin and oral Ivermectin in the treatment of Scabies in patient suffering from Diabetes mellitus. This comparative clinical trial was carried out in the outpatient department of Dermatology & Venereology, Diabetic Association Medical College Hospital (DAMCH), Faridpur from January 2012 to December 2012. A total 60 cases were enrolled purposively and divided into 2 groups. Group I received 2 doses oral Ivermectin and group II treated with 5% permethirn cream. Patients were followed up at the 3rd and 4th week. Total 86.6% patients of Ivermectin group and 90% of permethrin group were cured. Though permethrin showed somewhat more effective, the difference was not statistically significant. The study found that both ivermectin and permethrin were similarly effective in the treatment of scabies in patients suffering from Diabetes Mellitus.

Ocular thelaziasis in a 7-month-old infant.

Human thelaziasis is a zoonotic eye disease caused by a nematode parasite called Thelazia. In India, seven human cases of Thelazia have been reported earlier. This is the fi rst case report of an infant infected with Thelazia. During the month of July, 2012, the infant was presented with an eye problem to the eye clinic from a village of Dibrugarh. Five worms (three female and two male) were recovered from the left eye of the infant. Thelazia infection is rare in infant, and report of this case is suggestive of prevalence of infection in the area and warrants further investigation.

Gender Disparity in Autopsy Findings: How Much is It.

Bangladesh is densely populated country where male and female ratio is closer to each other. This descriptive study investigates the gender disparity of postmortem examination findings among 7 districts in the Rajshahi division of Bangladesh. Postmortem (PM) examination stations were located in Rajshahi, Rangpur, Bogra and Dinajpur Medical Colleges & Pabna, Natore and Chapai Nawabganj Sadar Hospitals. The findings of the autopsy reports (Total 3164) over the two years (2004 & 2005) were collected retrospectively from the register book of the authority. In this study we wanted to find out gender disparity - if exists in PM examination findings and, to what extent. Manually verified data were analyzed employing SPSS/WIN V-11.5. An obvious gender disparity existed in overall occurrence of unnatural deaths, male predominate female victims (M: F ratio = 1.51:1). A significant association existed in death circumstances & gender (p<0.0001); male (634) outnumbered female (250) in homicidal deaths, in suicidal deaths female (612) outnumbered male (364) and in accidental deaths male (583) outnumbered female (135). This classical gender difference in death circumstances remains similar to our national context. Findings of this study revealed an obvious gender difference in the overall numbers of cadaveric PM examination. Males were more victimized than females in majority of medico-legal aspects analyzed, except in suicidal cases.

Survey of mosquito species in Nagaland, a hilly state of north east region of India.

In an entomological study conducted during monsoon and post- monsoon season in the hilly state of Nagaland, a total number of 58 mosquito species under 11 genera were recorded. Out of these, 21 species viz., Aedes aegypti, Ae. nigrostriatus, Ae. annandalei, Ae. vittatus, Ae.caecus, Ae. vexans, Armigeres kuchingensis, Culex fuscocephala, Cx. pseudovishnui, Cx. murrelli, Cx. brevipalpis, Cx. epidesmus, Cx. minor, Cx. whitmorei, Coquilittidae crassipes, Malaya jacobsoni, Ml. genurostris, Toxorhynchites splendens, Uranotaenia campestris, Mansonia dives and Ma. annulifera were recorded for the first time from this state. Eleven mosquito species recorded earlier were not detected in the present study. Thus, with the addition these 11 species, the total mosquito fauna of the state goes up to 69. All the recognized vectors of malaria in the northeast and the vectors of Japanese encephalitis and dengue are recorded in the present study.

Surgical experience with a huge supratentorial primitive neuroectodermal tumour in a 3 years old boy.

The concept of Primitive Neuroectodermal Tumor (PNET) has been evolving for many years, since its nomenclature has been done. A 3 years old boy presented with unable to stand and walk, vertigo, vomiting and visual disturbances. MRI of brain revealed suggestive of malignant tumour with intratumoral hemorrhage involving the frontotemporo- parietal region. A gross total removal of tumor was achieved through craniotomy. The pathological finding was consistent with PNET. This case is an exclusive one as it was huge size. Supratentorial PNETs are rare tumour and carry poor prognosis. Newer modalities of treatment should be tried to improve survival.

Introduction of routine zinc therapy for children with diarrhoea: evaluation of safety.

On 8 May 2004, the World Health Organization (WHO) and the United Nations Children's Fund (UNICEF) recommended routine administration of zinc in the management of children, aged less than five years, with acute diarrhoea. In making the recommendation, WHO and UNICEF also suggested careful monitoring for adverse events associated with routine administration of zinc, particularly unusual or excess vomiting. The study assessed, in a phase IV trial, i.e. post-marketing surveillance of zinc, the occurrence of adverse events during the first hour after the administration of the first dose of zinc in children with acute or persistent diarrhoea. The study was conducted at the Dhaka Hospital of ICDDR,B and at an outpatient clinic operated by a local health NGO-Progoti Samaj Kallyan Protisthan (PSKP), Dhaka, Bangladesh. Eligible children, aged 3-59 months, were treated with 20 mg of zinc sulphate provided in a dispersible tablet formulation. The children were observed for 60 minutes following the initial treatment with zinc for adverse events, with particular attention given to vomiting or regurgitation. During the one-year observation period, 42,440 children (male 57% and female 43%) received zinc, and 20,246 (47.8%) of them were observed. Regurgitation and/or vomiting occurred in 4,392 (21.8%) of the children; 90.8% of these children had vomiting only once, 8.7% twice, and 0.5% more than twice. No children revisited the hospital for recurrent vomiting following their discharge. A significant proportion of infants and children may experience vomiting or regurgitation, usually once, following the administration of the first dose of zinc. This is a transient phenomenon that did not impact on continuation of treatment with zinc.

Biodiversity of mosquitoes in Manipur State and their medical significance.

Entomological studies conducted during monsoon and post-monsoon season in Manipur State revealed the presence of fifty-five species of mosquitoes under ten genera. Out of the seventeen Anopheles species recorded, Anopheles aconitus, An. dirus and An. nivipes were recorded for the first time from the state. The present study has confirmed the existence of An. dirus, the major malaria vector in the Northeast from a selected area of the state. Among Culicines, four species viz., Aedes nigrostriatus, Malaya genurostris, Aediomyia catasticta and Toxorhynchites splendens which were not reported earlier from this state have been recorded in the present study. With the addition of these seven species of mosquitoes to the earlier record of mosquitoes so far reported from Manipur, the mosquito fauna swells up to one hundred and eleven including the major vectors of malaria of the Northeast and the potential vectors of Japanese encephalitis and dengue virus transmission in India.

Low osmolar oral rehydration salts solution in the treatment of acute watery diarrhoea in neonates and young infants: a randomized, controlled clinical trial.

To compare the efficacy and safety of low osmolar oral rehydration salts solution (ORS-75) (mmol/L: Na+ 75, osmolarity 245) with that of World Health Organization-recommended ORS (ORS-90) (mmol/L: Na+ 90, osmolarity 311 ) in the treatment of acute watery diarrhoea in neonates and very young infants, a randomized double-blind, controlled clinical trial was carried out at the Clinical Research and Service Centre of ICDDR,B: Centre for Health and Population Research, Dhaka, Bangladesh, during January 1998-December 1999. Infants, aged < or = 2 months, presenting with a history of watery diarrhoea of < or = 72 hours, with no or some dehydration and without any systemic illness, were randomly assigned to receive either ORS-75 or ORS-90 for the correction and subsequent prevention of dehydration. Infants were studied for a maximum of five days. Total stool output, stool frequency, and requirement for ORS were outcome measures. Serum electrolytes were measured at 24 hours after admission to monitor serum sodium imbalance. Seventy-three infants received ORS-75, and 71 received ORS-90. Both the groups were comparable in their baseline characteristics. Diarrhoea resolved within five days in 53% and 66% of infants receiving ORS-75 and ORS-90 respectively (p = 0.3). Total stool volume [median (inter-quartile range) 132 (65-280) vs 139 (70-259) g/kg, p = 0.9], during the study period, was not significantly different between the two groups. Total stool frequency [31 (16-51) vs 35 (16-53), p = 0.9] and total ORS intake [192 (96-374) vs 209 (134-317) mL/kg, p = 0.7] were similar between the groups. No infants developed late evidence of hypernatraemia, irrespective of treatment. The results of the study indicate that ORS-75 is as safe as standard ORS-90 in the treatment of acute watery diarrhoea in neonates and very young infants and is effective in correcting and preventing dehydration.

A focus of lymphatic filariasis in a tea garden worker community of central Assam.

A survey for lymphatic filariasis was conducted among tea garden workers of central Assam. Of the 656 night blood samples examined, 31 were found positive for Wuchereria bancrofti parasite (microfilaria rate 4.7%). Microfilaria rate was higher in male (7.3%) than females (2.1%). Culex quinquefasciatus was incriminated as vector mosquito.

Entomological observations on dengue vector mosquitoes following a suspected outbreak of dengue in certain parts of Nagaland with a note on their susceptibility to insecticides.

Three species of Aedes viz., Aedes albopictus, Aedes aegypti and Aedes annandalei were detected from different breeding sources in and around human habitats during entomological study conducted following an outbreak suspected to be of dengue (which occurred during, 1994) in parts of Medziphema PHC area of Nagaland in two different points of time ie., in the year, 1994 and, 2000. The potential dengue vector, Aedes albopictus showed high preponderance by breeding in all types of containers searched with high Breteau Index (BI) value of 85.0 and 72.72 recorded in, 1994 and, 2000 respectively whereas the BI value for other potential vector, Aedes aegypti was recorded low (4.9) in the year, 1994 with a substantial increase (31.81) in, 2000. The change in ecosystem along with the process of urbanization has facilitated the growth of these dengue vector mosquitoes in the area of investigation. Adults of both Aedes aegypti and Aedes albopictus were found to be susceptible to DDT, dieldrin and malathion in insecticide bioassay carried out using WHO test kit.
