Comparative Study between the Use of Pigtail Catheters and Traditional Chest Tube Drain in Cases with Pneumothorax.

Background Pneumothorax is a condition in which air or other gas is present in the pleural cavity. Mainstay of management of pneumothorax is to remove the air from the pleural space usually done by chest tube insertion. There is still uncertainty whether minimal invasive management with pigtail catheter is sufficient for the management of pneumothorax. Objective To find the effectiveness, safety, tolerability, efficacy of pigtail catheters and large bore chest tubes. Method Prospective comparative study was done in Dhulikhel Hospital between August 2019 till August 2021. Chest tube insertion used to be the only available treatment modality till December 2020 (15 months). Following January 2021 after obtaining ethical clearance for use of pigtail insertion for pneumothorax, this treatment modality was done (8 months). Result Among 76 patients, 52(68.4%) underwent a large bore chest tube and 24 (34.6%) pigtail catheter patients. Mean age of the patients was 48 years (SD 18.01). Duration of hospital stay and length of hospital stay was more in large bore catheters and less in pigtail catheters. Eight hours post tube placement of the expansion of the lungs was present in pigtail and was statistically significant. Pain killer used in pigtail catheters was limited to Non-steroidal anti-inflammatory drugs, for large bore catheter opioids were added and were statistically significant. Conclusion Pigtail catheter is nearly effective as compared to traditional wide bore catheters.

Physician's Perception about the Use of PPE, COVID-19 Prevention and Management in Bangladesh.

This study aims to explore physician's perceptions about the use of Personal Protective Equipment (PPE), COVID prevention, and management during the COVID pandemic since knowledge on these might explain the reason behind infection and death of physicians in Bangladesh at an unexpected rate. This cross-sectional study was conducted based on an online questionnaire on 346 physicians (n=346) by the Department of Gastroenterology of Mymensingh Medical College Hospital, Bangladesh from 15th July 2020 to 14th September 2020. Physicians of different health care facilities across Bangladesh were invited to take part. Knowledge on specific points of the questionnaire was evaluated, scored, and compared between different groups by Independent sample t-test. Mean knowledge score between the respondents working up to 8 hours and beyond 8 hours per day was 17.28±1.28, 16.90±1.40 respectively (p=0.03). Mean knowledge score observed between graduate and post-graduate physicians and work experience of 5 years and beyond 5 years were 17.26±1.36 vs. 17.16±1.27; (p=0.40), 16.87±1.75 vs. 17.27±1.21; (p=0.11) respectively. Physician's safety should be first concern that is highlighted through proper use of PPE and prevention of COVID. Patient management skills would be better if physicians are trained well on infection prevention and control which in turn will reduce infection and death of physicians.

Value of Serum Adenosine Deaminase (ADA) in Distinguishing between Tuberculous and Non-tuberculous Lymphadenopathies.

Persistent lymphadenopathy with or without fever is often a diagnostic challenge to the physician which are usually caused by infection like tuberculosis, hematological malignancy (lymphoma, leukemia), connective tissue diseases (SLE, RA, Sjogren's syndrome etc.), sarcoidosis, storage diseases, drugs (like phenytoin) in Bangladesh. To establish the cause of lymphadenopathy, we need to do a good number of investigations including invasive tests like FNAC or histopathology of the involved lymph node. In many instances these are not possible due to unavailability or cost. But for last few years the adenosine deaminase is an enzyme involved in purine catabolism and its significance in the diagnosis of tuberculosis has been demonstrated by many studies. In addition to tuberculosis, elevated serum adenosine deaminase has also been found in lymphoma, sarcoidosis and some connective tissue diseases. The study was intended to assess if there are any significant diagnostic difference in the level of elevated adenosine deaminase between tubercular and different types of non tubercular lymphadenopathy. It included 68 patients, equally divided into two groups, tuberculous lymphadenitis and non-tuberculous lymphadenopathy. Epitheloid granuloma with caseation necrosis in biopsy or FNAC was taken as case definition of tuberculous lymphadenitis. Causes of non-tuberculous lymphadenopathy were established on the basis of clinical findings, laboratory investigations and histopathological diagnosis of biopsy or FNAc materials. This cross-sectional observational study was done in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh over a period of one year and participants of 18 years and above of both genders were included as per consecutive sampling technique. Serum ADA concentrations were estimated by enzymatic method. Mean serum ADA concentration was 25.52±7.11 in tuberculous lymphadenitis and in non-tuberculous lymphadenopathy patients it was 27.29±15.91U/L with no significant difference (p=0.480). The non-tuberculous lymphadenopathy group consisted of Hodgkin disease (n=9), non-Hodgkin lymphoma (n=10), sarcoidosis (n=2), reactive lymphadenitis (n=9) and other lymphadenopathy group (n=4) (that consisted one case of each of follicular hyperplasia, adult Still disease, sinus histiocytosis and Castleman's disease). The mean ADA of these groups was 32.77±13.14U/L, 46.40±46.10U/L, 13.94±2.81U/L and 21.75±3.17U/L respectively. Tuberculous lymphadenitis patients had significantly higher serum ADA than persistent reactive lymphadenitis. On the other hand, there were statistically significant elevation of serum ADA in non-Hodgkin lymphoma and sarcoidosis than in tuberculous lymphadenitis.

Glycaemic Status of Asthma Patients Using Inhaled Fluticasone.

Inhaled fluticasone is used in asthma for long duration. However, it's adverse effect on glycaemia is debatable. This study observed the outcome of inhaled fluticasone in asthma patients. A cross sectional comparative study was conducted among the normoglycaemic asthma patients aged 18 years and above attending outpatient department of Internal Medicine and Respiratory Medicine department of Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from June 2017 to May 2018. Study group were getting inhaled fluticasone for minimum three months whereas comparative group were not on any steroids. Each group had 35 eligible participants (n=70). Spirometry and plasma glucose at fasting and 2-hour after 75gm oral glucose intake were measured along with HbA1c%. Statistical analysis was done using SPSS 21.0. In study group mean plasma glucose at fasting was 5.27±0.48mmol/L, 2-hour after 75gm oral glucose was 6.04±1.21mmol/L and mean of HbA1c was 5.57±0.41% whereas in comparative group these were5.17±0.59mmol/L, 5.69±1.09mmol/L, 5.47±0.40% respectively (p=0.25, 0.20, 0.75 respectively). There was no specific co-relation between duration of use of fluticasone inhaler and glycaemic parameters like plasma glucose at fasting, 2-hour after 75gm oral glucose and HbA1c% (r=0.016, p=0.46; r=0.015, p=0.47; r=0.019, p=0.42 respectively). Use of inhaled fluticasone for 3months or more has insignificant effect on plasma glucose levels of asthma patients. Duration of use of inhaled fluticasone has no specific correlation with plasma glucose and HbA1c values.

Fixation of subcondylar fractures of the mandible: a randomized clinical trial comparing one trapezoidal plate with two miniplates.

Subcondylar fracture of the mandible accounts for 25-35% of all mandibular fractures. In the past, most subcondylar fractures were managed non-surgically. The traditional method of fixation for subcondylar fractures uses two miniplates; however some bench studies have reported that trapezoidal plates are superior. The aim of this study was to compare the outcomes of subcondylar fractures fixed either with two non-parallel straight miniplates or with one trapezoidal plate. A randomized clinical trial was designed and implemented. Fifty-two consecutive patients with subcondylar fractures were recruited. All patients underwent surgery via a retromandibular approach. The time taken for fixation of the plate after fracture reduction and postoperative outcomes and complications were compared between the groups. The trapezoidal plates were superior in terms of ease of adaptation and time taken for fixation (P= 0.0001). Plate fracture was observed only in the two miniplates group, in four (16%) patients. Outcomes were similar in the two groups in terms of occlusion, mouth opening, protrusion, and lateral excursion. In conclusion, both systems - two miniplates and the trapezoidal plate - provide functionally stable fixation. The outcome was significantly better for the trapezoidal plate than for two miniplates regarding the time taken for insertion and ease of adaptation, but not for other parameters.

Toxoplasmosis Presenting as Nonhealing Cutaneous Ulcer.

INTRODUCTION: Systemic manifestation of toxoplasmosis is commonly seen in immune-compromised individuals. Skin manifestations are seen commonly in conjunction with systemic features. Isolated cutaneous toxoplasmosis is extraordinarily rare in immunocompetent patients. Case Description. A 64-year-old female presented to the Dermatology Outpatient Department (OPD), with a nonhealing ulcer over dorsum of the left hand for one year. The patient did not have any systemic diseases. Serology tests were negative. An incisional biopsy of the lesion revealed dense inflammatory cell infiltrates comprising predominantly of plasma cells and lymphocytes, multinucleated giant cells, and focal abscess formation in the dermis. Periodic Acid Schiff (PAS) stain showed organisms in the dermis with morphological resemblance to tachyzoites of Toxoplasma gondii. CONCLUSION: Though rare, a possibility of primary cutaneous toxoplasmosis should always be considered and looked for, even in immunocompetent patients presenting with chronic nonhealing ulcers.

A Rare Case of Fibrous Hamartoma of Infancy: A Clinicopathological Diagnosis at a Tertiary Hospital, Eastern Nepal.

BACKGROUND: Fibrous hamartoma of infancy is a rare soft tissue lesion of infants and young children with characteristic triphasic morphology. CASE DESCRIPTION: An 18-month-old female child was presented with complaints of swelling over right leg shin since birth. On examination, a lump of size 7x3 cm was identified which was mobile and nontender. Local excision was performed and tissue sent for histopathological examination. On gross examination, a globular, capsulated, firm to hard tissue had cut section revealing solid grey-white to grey-brown lesion with myxoid areas identified. Microscopic examination revealed a poorly circumscribed lesion comprising intersecting trabeculae of fibrous tissue, areas of immature oval and stellate cell within myxoid matrix, and varying amounts of interspersed mature fat cells. CONCLUSION: Even though fibrous hamartoma of infancy is a rare benign entity with limited clinical knowledge, proper diagnosis is mandatory as its prognosis is excellent.

Impact of the learning environment on career intentions of paediatric interns.

BACKGROUND: High childhood disease burdens in South Africa (SA) prioritise the need for careers in paediatrics. Experiences of junior doctors during internship may influence career trajectories in a direction that is discordant with national health priorities. OBJECTIVE: To explore the influence of the learning environment and demography on career intentions of SA paediatric interns. METHODS: This cross-sectional study involved sampling intern groups at the start and completion of internship in paediatrics to determine their career intentions. A validated version of the Postgraduate Hospital Educational Environmental Measure was used to measure perceptions of the learning environment (LE) in the post-paediatric internship cohort. Measures of the LE in combination with demographic factors were compared with career intentions. Associations were determined by t-tests or analysis of variance and χ2 tests. RESULTS: A total sample size of 422 was obtained from two separate cohorts, which were demographically similar except for age. Most interns (88.4%) intended to remain in SA, with 72.6% indicating an intention to practise in the public healthcare sector. There was a high intention to specialise (85.9%), and 60.2% were keen on a career that involved children. Previous educational exposure and demographic factors other than gender did not significantly influence career intentions. Perceptions of the LE significantly influenced decisions to stay in SA's public sector and to care for children. The decision to specialise, however, was not influenced by demographic variables or perceptions of the LE. CONCLUSIONS: Paediatric interns from diverse sociocultural and educational backgrounds had similar career intentions. Most interns were keen to work with children in SA's public sector. However, learning experiences during internship significantly influence these intentions and have the potential to drive young doctors away from SA, its public health service and paediatric care. Ensuring that training and support of interns are optimised is essential if SA is to align its healthcare needs with the aspirations of its future healthcare workers.

The significance of cytomegalovirus in children with pneumonia admitted for mechanical ventilation.

BACKGROUND: The pathogenic role of cytomegalovirus (CMV) among children with pneumonia is not clear. OBJECTIVES AND DESIGN: We describe the outcome of children on mechanical ventilation with 'probable' CMV-related pneumonitis (CMV DNA polymerase chain reaction [PCR] positive as well as clinical and imaging features of CMV on ganciclovir) and children with pneumonia and CMV infection (CMV DNA PCR-positive without clinical and imaging features of CMV and not on ganciclovir therapy) at a paediatric intensive care unit in South Africa between 2011 and 2013. CMV viral loads were measured in non-bronchoscopic bronchoalveolar lavage fluid (NBBALF), plasma and whole-blood samples. RESULTS: Of the 97 children enrolled, 38 had CMV-related pneumonitis, 27 had pneumonia and CMV infection and 32 had pneumonia without CMV infection (negative CMV DNA PCR). Survival in the three groups was respectively 73.7% (P < 0.05), 92.6% (P < 0.05) and 88.0%. The difference in outcome could be accounted for by variance in the prevalence of human immunodeficiency virus (HIV) infection (respectively 60.5% and 29.6%, P < 0.05). A higher CMV viral load in NBBALF and plasma was seen in cases of CMV-related pneumonitis than in pneumonia with CMV infection: respectively log 5.20 vs. log 4.10 (P < 0.05) and 4.56 vs. 3.47 (P < 0.05). CONCLUSIONS: HIV-infected children on mechanical ventilation with CMV-related pneumonitis on ganciclovir have poor outcomes. Randomised placebo-controlled studies on ganciclovir are required.

The clinical profile and outcome of children with West syndrome in KwaZulu-Natal Province, South Africa: A 10-year retrospective review

Background. West syndrome (WS) is a rare epileptic encephalopathy of infancy. There is currently no research on the incidence or prevalence of WS in Africa.Methods. We aimed to describe the outcome of children with WS at a quaternary-level hospital in KwaZulu-Natal, South Africa (SA). This was a retrospective chart review conducted on patients diagnosed with WS over a 10-year period. Eight children (males, n=7; African, n=6; Asian, n=2) identified with WS out of 2 206 admitted with epilepsy. The median age (range) at diagnosis was 7.5 (1 - 9) months. The average time between onset of epileptic spasms and diagnosis was 3.1 months.Results. Six patients had abnormal neuroimaging (atrophy (n=2); corpus callosum agenesis (n=2); tuberous sclerosis (n=1); focal dysplasia (n=1)). Drug management included sodium valproate (n=8), topiramate (n=7) and levetiracetam (n=3). Subsequent definitive treatment was intramuscular adrenocorticotrophic hormone (n=3), vigabatrin (n=2) and oral prednisone (n=4). Four (50%) patients had complete seizure remission (neuromigratory disorder (n=2); tuberous sclerosis (n=1); and idiopathic (n=1)) and 4 had partial remission (neonatal complications (n=3); idiopathic (n=1).Discussion. Most of our patients had symptomatic WS, with 50% remission on treatment. Outcomes were poorer in our study when compared with those in published data.Conclusion. Further collaborative studies are still needed to evaluate the true impact and prevalence of WS in SA

Can sliding-window correlations reveal dynamic functional connectivity in resting-state fMRI?

During the last several years, the focus of research on resting-state functional magnetic resonance imaging (fMRI) has shifted from the analysis of functional connectivity averaged over the duration of scanning sessions to the analysis of changes of functional connectivity within sessions. Although several studies have reported the presence of dynamic functional connectivity (dFC), statistical assessment of the results is not always carried out in a sound way and, in some studies, is even omitted. In this study, we explain why appropriate statistical tests are needed to detect dFC, we describe how they can be carried out and how to assess the performance of dFC measures, and we illustrate the methodology using spontaneous blood-oxygen level-dependent (BOLD) fMRI recordings of macaque monkeys under general anesthesia and in human subjects under resting-state conditions. We mainly focus on sliding-window correlations since these are most widely used in assessing dFC, but also consider a recently proposed non-linear measure. The simulations and methodology, however, are general and can be applied to any measure. The results are twofold. First, through simulations, we show that in typical resting-state sessions of 10 min, it is almost impossible to detect dFC using sliding-window correlations. This prediction is validated by both the macaque and the human data: in none of the individual recording sessions was evidence for dFC found. Second, detection power can be considerably increased by session- or subject-averaging of the measures. In doing so, we found that most of the functional connections are in fact dynamic. With this study, we hope to raise awareness of the statistical pitfalls in the assessment of dFC and how they can be avoided by using appropriate statistical methods.

The research component of specialist registration--a question of alligators and swamps? A personal view.

The recent implementation of the research requirement for specialist registration presents difficulties with regard to the provision of research supervision, particularly in those medical schools that previously followed the path of qualification via the Colleges of Medicine of South Africa examinations. The differences between the requirements for research supervision as stated in the Health Professions Council of South Africa memorandum and those of the Committee for Higher Education are causing disparities between medical schools similar to those that led to the memorandum in the first place. While the research component of specialist training can only improve the quality of both patient care and academic endeavour, it requires an enormous investment of time on the part of both the specialist trainees and their supervisors. In order to deal with this, specific issues outlined in the article need to be addressed.

Screening retreatment tuberculosis patients for drug resistance in mid-west Nepal: how well are we doing?

SETTING: Multidrug-resistant tuberculosis (MDR-TB, defined as resistance to isoniazid and rifampicin) is poorly detected in Nepal; one reason may be poor functioning of culture and drug susceptibility testing (CDST) services for retreatment tuberculosis (TB) patients. OBJECTIVES: To determine, among retreatment TB patients in mid-west Nepal, 1) the number of patients registered for treatment between July 2011 and July 2012; 2) the number submitting sputum specimens for CDST to the Central Reference Laboratory (CRL), Kathmandu, along with the results; and 3) the length of time for submission and receipt of specimens. DESIGN: Retrospective cohort study involving the review of treatment and laboratory registers from the Nepalgunj TB Referral Centre and the CRL. RESULTS: Of 431 retreatment patients, 66 (15%) submitted sputum samples, of which 63 reached the CRL. Of these, 39 (62%) were culture-positive; 13 (33%) patients had MDR-TB. The CDST results of 19 patients were received back at the TB Referral Centre. The median turnaround time from sending specimens to receipt of results at the TB Referral Centre was 119 days. CONCLUSION: Less than 10% of retreatment TB patients in mid-West Nepal had CDST results recorded, leading to the underdiagnosis of MDR-TB in the region. Urgent solutions are needed to rectify this problem.

Contexte : La tuberculose multi-résistante (TB-MDR, définie comme une résistance à l'isoniazide et à la rifampicine) est mal détectée au Népal; une des raisons pourrait être le mauvais fonctionnement des services de culture et de tests de sensibilité aux médicaments (CDST) pour les tuberculeux en retraitement.Objectifs : Déterminer parmi les patients tuberculeux du Centre Ouest du Népal 1) le nombre de patients enregistrés pour un traitement de juillet 2011 à juillet 2012; 2) le nombre de patients ayant eu un examen de crachats pour CSDT au laboratoire central de référence (CRL) à Katmandou ainsi que les résultats; et 3) le délai de fourniture et de réception des échantillons.Schéma : Etude rétrospective de cohorte par revue des registres de traitement et de laboratoire du centre de référence de la TB Nepalgunj et du CRL.Résultats : Sur 431 patients en retraitement, 66 ont fourni des échantillons de crachats dont 63 (15% du total) sont parvenus au CRL. Parmi eux, 39 (62%) étaient positifs; 13 patients (33%) avaient une TB-MDR. Les résultats du CDST sont parvenus au centre de référence de la TB pour 19 patients. Le délai médian entre l'envoi des échantillons et la réception des résultats au centre de référence de la TB était de 119 jours.Conclusion : Dans le Centre Ouest du Népal, moins de 10% des patients ont eu des résultats d'examens de CSDT, ce qui induisait un sous-diagnostic de la TB-MDR dans cette région. Il est urgent de trouver des solutions à ce problème.

Marco de referencia: La detección de la tuberculosis multidrogorresistente (TB-MDR), que se define como la presencia de resistencia a isoniazida y rifampicina, es precaria en Nepal. Una de las causas podría ser una deficiencia en el funcionamiento de los servicios de cultivo y pruebas de sensibilidad a los medicamentos (CDST), en el caso del retratamiento de los pacientes tuberculosos.Objetivos: Determinar los siguientes aspectos de los pacientes registrados en retratamiento en el occidente medio de Nepal: 1) el número de pacientes registrados en tratamiento entre julio del 2011 y julio del 2012; 2) el número de pacientes cuyas muestras de esputo se remitieron al Laboratorio Central de Referencia (CRL) en Katmandú para CDST y los resultados obtenidos; y 3) el tiempo transcurrido entre la obtención de la muestra y la recepción de los resultados.Métodos: Fue este un estudio retrospectivo de cohortes en el cual se examinaron los registros de tratamiento y de laboratorio del Centro de Referencia de Tuberculosis de Nepalgunj y del CRL.Resultados: De los 431 pacientes en retratamiento, en 66 se recogieron muestras de esputo y de estas muestras, 63 llegaron al CRL (15%). De esos, 39 obtuvieron un cultivo positivo (62%) y 13 pacientes exhibieron TB-MDR (33%). En el Centro de Referencia de TB, se recibieron los resultados del cultivo y las pruebas de sensibilidad de 19 pacientes. La mediana del tiempo necesario a la obtención del resultado desde el envío de las muestras fue 119 días.Conclusión: En menos del 10% de los pacientes en retratamiento se practicaron el CDST a los medicamentos antituberculosos en el occidente medio de Nepal, lo cual origina una deficiencia en el diagnóstico de la TB-MDR en la región. Se precisan con urgencia intervenciones que solucionen esta carencia.

How to change perceptions on feeding in neonatal care

The transmission of HIV through breastmilk; with the potential to infect the newborn; has had a major impact on child health worldwide. Although South African studies confirmed that exclusive breastfeeding reduced rates of mother-to-child transmission of HIV; the recommendation of formula feeding for HIV-exposed newborn infants; provided their mothers had the facilities for safe preparation of formula milk and complied with the AFASS criteria (formula feeding to be Acceptable; Feasible; Affordable; Sustainable; Safe); was introduced. Observations made by the nursing staff; fully aware of the risks of formula feeding; in the neonatal unit at King Edward VIII Hospital in 2009 showed that an increasing number of small; sick newborns were being formula fed.By conducting focus group discussions with nurses; mothers and counsellors and teasing out the confusions and misconceptions; relevant information was imparted to the groups to allow them to re-consider their misconceptions. Within a period of 2 months nurses were confident about re-counselling mothers with respect to appropriate feeding choices. HIV-positive mothers were trained to flash-heat their milk. Subsequently; policies for the unit were derived from the focus group discussions. In addition; regional hospitals in the Durban area (eThekweni) considered the introduction of flash-heating to their units. The South African Department of Health opted for infants to receive prophylaxis with daily nevirapine as long as they are breastfed; and the Nutrition Directorate decided to withdraw the issue of free replacement feeds in HIV-exposed babies. KZN was the first province to institute this policy. The Department of Health has recommended that neonatal units no longer encourage HIV-infected mothers to flash-heat their breastmilk unless the infant is not receiving ARV prophylaxis or the mother is not on treatment

HIV-Associated Tuberculosis in the Newborn and Young Infant.

Each year, approximately 250 000 women die during pregnancy, delivery, or postpartum. Maternal mortality rates due to tuberculosis (TB) and HIV in Sub-Saharan Africa now supersede obstetric-related causes of mortality. The majority of cases occur in population-dense regions of Africa and Asia where TB is endemic. The vertical transmission rate of tuberculosis is 15%, the overall vertical transmission rate of HIV in resource-limited settings with mono- or dual-ARV therapy varies from 1.9% to 10.7%. If the millennium development goals are to be achieved, both HIV and TB must be prevented. The essential aspect of TB prevention and detection in the newborn is the maternal history and a positive HIV status in the mother. Perinatal outcomes are guarded even with treatment of both diseases. Exclusive breast feeding is recommended. The community and social impact are crippling. The social issues aggravate the prognosis of these two diseases.

Clinical manifestations and outcome in HIV-infected young infants presenting with acute illness in Durban, South Africa.

OBJECTIVES: In young infants, early development of symptomatic HIV infection increases the risk of morbidity and mortality. A prospective study was conducted over a 1-year period in a region with a high burden of HIV in order to describe the clinical presentation of HIV infection in infants aged between 0 and 59 days on attendance at hospital and the factors associated with the need for urgent hospital management. METHODS: Sick young infants presenting to the King Edward VIII Hospital, Durban between February 2003 and January 2004 were enrolled. After systematic evaluation by a primary health worker, an experienced paediatrician determined the primary diagnosis and need for urgent hospital management. Comparisons of these assessments were stratified by HIV status. Children were classified as HIV-uninfected (HIV ELISA-negative), HIV-exposed-but-uninfected (HIV ELISA-positive and HIV RNA PCR-negative), HIV-infected (HIV ELISA-positive and HIV viral load >400 copies/ml). RESULTS: Of 925 infants enrolled, 652 (70·5%) had their HIV status determined: 70 (10·7%) were HIV-infected, 271 (41·6%) HIV-exposed-but-uninfected, and 311 (47·7%) HIV-uninfected. Factors associated with an increased probability of being HIV-infected included if the mother had children from more than one sexual partner, if the infant had had contact with a tuberculosis-infected person or if the HIV-infected mother and/or her exposed infant failed to receive nevirapine prophylaxis. Signs of severe illness were more frequently encountered in HIV-infected than in HIV-exposed-but-uninfected infants, including the prevalence of chest in-drawing (20·3% vs 8·8%, p = 0·004) and severe skin pustules (18·6% vs 8·6%, p = 0·01). Among infants requiring urgent hospital management, observed or reported feeding difficulties and severe skin pustules were more common in HIV-infected than uninfected infants. More HIV-infected infants (12·9%) required hospitalisation than those who were HIV-exposed-but-uninfected (7·7%) or uninfected (7·4%). Primary diagnoses of pneumonia, sepsis or oral thrush were more frequently seen in HIV-infected than exposed-but-uninfected or HIV-uninfected children. CONCLUSION: Early recognition and triaging of infants suspected of having HIV infection provides an opportunity for early diagnosis and treatment which could prevent the adverse impact of rapidly progressive HIV disease.

Prevalence of metabolic syndrome (METS) using IDF 2005 guidelines in a semi urban south Indian (Boloor Diabetes Study) population of Mangalore.

OBJECTIVE: To identify metabolic syndrome (MetS) prevalence using International Diabetes Federation (IDF) 2005 guidelines in a semi urban south Indian (Boloor Diabetes Study) population of Mangalore. METHODS: Population of randomly selected adults > or =20 years living in Boloor locality who were available for the house to house survey were assessed for the following: anthropometric variables; blood pressure; fasting blood glucose and lipid profile. Among 800 responders; 300 men, 500 women, 551 were examined (68.8%). Fasting plasma glucose as well fasting lipid profile could be done for 451 (147 men, 304 women) 81.85%; Data was analysed for prevalence of MetS and its individual components. Diagnosis of MetS was based on IDF 2005 criteria for Asian men and women. Intergroup comparisons were performed using student 't' test and Chi-square test. RESULTS: MetS was prevalent in 134 of 451 (29.7%); men 39 (26.5%) and women 95 (31.2%). Prevalence of individual components of MetS were as follows: increased waist circumference, (common component) present in all; elevated TG in 38.8%; low HDL-C in 59.7%; increased FPG in 57.4%; elevated SBP in 80.5% and DBP in 56.7%; body mass index (BMI) > or =25 kg/sq.m (obesity) in 58.9% Barring increased waist circumference which is the essential criteria for diagnosis of Mets, Systolic hypertension emerged as the most frequent component in the population followed by low HDL-C and elevated FPG. Elevated TG was less prevalent in this population. CONCLUSION: Prevalence of MetS in this semi urban population (Boloor) of Mangalore compares with MetS prevalence identified in cross sectional studies in India. Prevention and treatment of the predictive factors: dyslipidemias, hyperglycaemia, hypertension, together with enhanced physical activity may together reduce the prevalence of MetS.

Dialysis access pattern in incident haemodialysis patients at B & B Hospital, Kathmandu, Nepal.

The clinical practice guideline for vascular access in haemodialysis recommends the use of arteriovenous fistula (AVF) over a central venous catheter. AVF needs to be created sufficiently in advance of anticipated haemodialysis. However, many incident haemodialysis patients are still being dialyzed with central venous catheter at the time of first haemodialysis. This paper aims at presenting the pattern of dialysis vascular access in incident haemodialysis patients at our institution from July 2002 to July 2008 in a cohort of patients who were referred to us for creation of native AVF. A total of 100 patients (56 male and 44 female) with the mean age of 54 years were studied. Only 110.0% of patients were found to have AVF created in advance and the rest (89.0%) were dialyzed via central venous catheter. Of the 11 patients with AVF; 5 fistulas were created 3 months prior to the dialysis, 3 fistulas between 1 and 3 months prior and 3 less than a month of anticipated dialysis. Interestingly, 35.0% of total patients were seen by nephrologists only a month prior to the dialysis. Hence, an early referral of the chronic renal failure patients to the nephrologists and vascular access surgeons may overcome this problem.
