Abstract
Shoulder pain is a common musculoskeletal pain in the general population and results in significant disability, quality of life impairment and financial burden to the health care system. This cross-sectional study was carried out among purposively selected 61 adult patients with shoulder pain and or limited range of motion in the Department of Radiology and Imaging, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from September 2018 to August 2020 to determine the usefulness of USG in detection of common shoulder abnormalities, as an initial imaging modality using MRI as reference standard. The majority of the patients 25(40.98%) were in age group of 51-60 years with mean age of 52.98±10.85 years. In the dectection of rotator cuff pathology, the overall sensitivity, specificity and accuracy of USG for any complete tear were 100.0% each, for any partial tear were 79.71%, 96.57% and 91.80%, for any rotator cuff tear were 83.33%, 96.25% and 91.80%, and for any tendinosis were 90.48%, 99.37% and 96.31% respectively. The sensitivity, specificity and accuracy of USG were 88.23%, 92.59% & 90.16% for long head of biceps tendon sheath effusion, 100.0% each for long head of biceps tendon dislocation, 71.11%, 87.50% and 75.41% for glenohumeral joint effusion, and 58.06%, 96.67% and 77.05% for bursal effusion respectively. From this study, it is concluded that high resolution USG showed high sensitivity, specificity and accuracy compared to MRI in detecting common shoulder abnormalities, and could be considered as the first line imaging modality in the evaluation of shoulder pain.

Abstract
Abstract The current study aimed to investigate the relationship between polymorphisms in detoxifying (GSTM1, GSTT1, and GSTP1) genes and their association with colorectal cancer (CRC) in tobacco addicts of Pashtun ethnicity. Polymorphisms in the selected genes were genotyped in a case-control study consisting of 100 histologically confirmed male CRC patients and 100 birth-year and gender-matched healthy controls using the PCR−RFLP method. The GSTM1 null, and GSTT1 null genotypes were significantly contributed to the risk of CRC in the cases (OR= 3.131, 95% CI: 1.451−6.758, P = 0.004, and OR= 3.541, 95% CI: 1.716−7.306, P = 0.001, respectively), whereas the association observed for GSTP1 Val/Val (1.139, 95% CI: 0.356−3.644, P = 0.826) did not show statistical significance. The combined GSTM1 null and GSTT1 null showed a 41-fold increased risk (95% CI: 4.945−351.950, P = 0.001), while, the combined GSTM1 null and GSTP1 Ile/Val or Val/Val variant genotypes exhibited about 3-fold (95% CI: 1.196−7.414, P = 0.019) increased risk to CRC. Similarly, the combined GSTT1 null and GSTP1 Ile/Val or Val/Val variant genotypes showed about a 3-fold (95% CI: 1.285−8.101, P = 0.013) increased risk of CRC. In the combination of three GST genotypes, the GSTM1 null, GSTT1 null, and GSTP1 Ile/Val or Val/Val variant genotypes demonstrated a more than a 22-fold (95% CI: 2.441−212.106, P = 0.006) increased risk of CRC. Our findings suggest that GSTM1 and GSTT1 polymorphism and its combination with GSTP1 may be associated with CRC susceptibility in the Naswar addicted Pashtun population of Khyber Pakhtunkhwa, Pakistan.

Abstract
Outcome of acute ST-elevation myocardial infarction patients varies time to time. The present study was intended to find out the short-term treatment outcome of the patients admitted in hospital. This descriptive study was carried out in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from 15 January 2014 to 14 July 2014. A total of 100 patients admitted with Acute ST-elevation Myocardial Infarction confirmed on the presence of the (a) Typical chest pain of acute ST-elevation Myocardial Infarction (b) Electrocardiogram (ECG) evidence of ST segment elevation in two or more contiguous leads (c) Raised cardiac marker (Troponin I) were included in the study. Patients were randomly enrolled according to the inclusion and exclusion criteria and observe for one week. Data were processed and analyzed by using computer bases software SPSS version 19.0. Descriptive statistical methods were applied for data analysis. P value was considered as statistically significant when it is less than 0.05. Short-term treatment outcome of acute ST-elevation myocardial infarction include mechanical, arrhythmic, ischemic and inflammatory sequelae, as well as left ventricular mural thrombus. In addition to these broad categories, heart failure, arrhythmia, death are other common complications of AMI. The initiation of the complications usually results in explicit sign and symptoms of the acute MI patients. Learning of the complications in the post infarction period and the clinical syndromes develop with each complication, will allow the health care worker to evaluate and manage the complication appropriately.

Abstract
Radial artery occlusion (RAO) is now a major concern in transradial approach (TRA). RAO limits future radial artery use for further TRA, for as a conduit during CABG, for invasive hemodynamic monitoring and for creation of arteriovenous fistula for hemodialysis in Chronic Kidney Disease (CKD) patients through same vascular approach. The effect of duration of hemostatic compression of RAO is unknown in Bangladesh. This prospective observational study was conducted in the department of Cardiology, National Institute of Cardiovascular Diseases, Dhaka, Bangladesh (NICVD) from September 2018 to August 2019, to evaluate the effect of duration of hemostatic compression on the incidence of radial artery occlusion (RAO) after transradial percutaneous coronary intervention. A total of 140 patients underwent percutaneous coronary intervention (PCI) through TRA. RAO was defined as an absence of antegrade flow or monophasic flow or invert flow on Duplex study. In this study 70 patients (Group I) received 2 hours hemostatic compression after transradial PCI. Another 70 patients (Group II) received 6 hours hemostatic compression after transradial PCI. Radial arterial blood flow assessed at early (24 hours) and late (30 days) by color duplex study after the procedure in both groups. Early radial artery occlusion occurred in 4.3% of patients in Group I and 12.8% of patients in Group II, (p=0.04). Late radial artery occlusion occurred in 2.8% of patients in Group I and 11.4% of patients in Group II, the difference was statistically significant (p=0.04). From multivariate logistic regression analysis duration of hemostatic compression time 6 hours (p=0.01), post-procedural nitroglycerine use (p=0.03) and procedure time (p=0.03) were predictors of RAO. Shorter duration of hemostatic compression is associated with a lower incidence of early and late radial artery occlusion after transradial intervention.

Abstract
Hepatocellular carcinoma (HCC) is the fifth most common cancer in the world and the leading cause (possibly third) of cancer mortality. In a present scenario, HCC displays a challenging clinical problem worldwide. Good-quality ultra sound with careful evaluation of the hepatobiliary system can be a screening examination for HCC in patients at risk. The aim of the study was to determine the diagnostic accuracy of the Doppler sonography for differentiation of hepatocellular carcinoma (HCC) from other focal liver lesions. It was a cross-sectional survey, conducted in the Department of Radiology& Imaging, Mymensingh Medical College, Mymensingh, Bangladesh from January 2017 to December 2018. A total of 70 patients with space occupying lesions on ultrasound were included in this study while pregnant women were excluded. All patients were examined by gray scale ultrasonography, color Doppler and FNAC. To visualize the blood flow, standard color Doppler sonography was used for each lesion. Within the lesions, pulsed Doppler samples were assessed whenever possible on the basis of pulsatile flow & finally resistive index (RI) of intra-tumoral and peritumoral arterial flow was studied. After evaluating by Doppler sonography (CDFI and Spectral analysis), FNAC was done and the specimen was sent to the Department of Pathology for Cytopathological examination. Cytopathology were assessed for confirmation of positive and negative cases of HCC. The detection rate of arterial flow in malignant tumors was 85.1% and in benign lesions were 30.4%. Doppler spectrum analysis showed that the resistive index in primary malignant tumors were 0.76±0.12 and in metastatic tumors were 0.80±0.12 and below 0.6 in benign lesions. The difference was significant (p<0.001). This difference was related with its Cytopathological report. The arterial flow identified by CDFI within the liver lesion with RI >0.6 can be regarded as a criterion of malignant tumors and RI<0.6 can be regarded as benign lesions. This study concluded that the combination of color Doppler flow imaging and RI are more useful in differential diagnosis of liver neoplasms.

Abstract
From 2000 onwards dengue fever has been occurring at regular intervals in Bangladesh. Ultrasonography is a useful diagnostic procedure. This study was done, keeping this background in mind. Objective of this study was to identify the role of ultrasonography as a useful tool in early diagnosis of dengue haemorrhagic fever. This was a cross-sectional descriptive type of observational study. Results of ultrasonography, haematogy an immunology were observed in 2004 and 2019 in 32 patients on each occasion. In 2004 out of 32 patients 29 had positive ultrsonographic findings supported by corresponding haematological and immunological findings. In 2019 ultrsonography was done in three out of thirty two patients, all three had had positive ultra sonographic findings which were supported by haematological and immunological findings. Dengue fever has serious complications like plasma leakage which manifest in the form of ascites, pleural effusion, thick gallbladder wall etc. If such complications can be detected at an early stage many lives can be saved.

Abstract
Moringa oleifera Lam. has been used as a traditional medicine for the treatment of several
diseases. In this study, the antioxidant activity and simultaneous HPLC profiling of
polyphenolic compounds in 80% ethanol and water extracts of M. oleifera tender and
mature leaves available in Bangladesh were investigated. The 80% ethanol extract of M.
oleifera tender leaves contained high concentration and more amount of 3,4-
dihydroxybenzoic acid, (-) epicatechin and rosmarinic acid (201.32±1.94, 213.08±1.96
and 133.84±1.42 mg/100 g of dry extract, respectively) than that of mature leaves
(82.55±1.09, 141.86±1.10 and 16.23±0.76 mg/100 g of dry extract, respectively). On the
other hand, the water extract of M. oleifera tender leaves contained a high concentration of
catechin hydrate, trans-ferulic acid and quercetin (530.05±1.91, 166.38±0.90 and
771.74±1.34 mg/100 g of dry extract, respectively) than that of mature leaves
(207.21±0.90, 62.42±0.45 and 483.25±1.04 mg/100 g of dry extract, respectively). It was
also found that 3,4-dihydroxybenzoic acid, catechol, p-coumaric acid and trans-cinnamic
acid were detected only in 80% ethanol extract of M. oleifera leaves but syringic acid was
identified in the water extract. In DPPH free radical scavenging activity test, IC50 values
of 80% ethanol extract of tender leaves (EETL), 80% ethanol extract of mature leaves
(EEML), water extract of tender leaves (WETL) and water extract of mature leaves
(WEML) were found to be moderately significant (105.50±1.05, 115.00±1.14,
216.00±1.34 and 269.50±1.56 μg/mL, respectively) when compared to the IC50 value of
ascorbic acid, 3.32±0.07 μg/mL. The polyphenolic compounds are responsible for
antioxidant activity. On the basis of the present study, it can be suggested that the leaves
show antioxidant activity and it’s contained a significant amount and different types of
polyphenolic compounds. Standardized polyphenolic compounds from M. oleifera leaves
could be used as a better source of natural antioxidant supplement.

Abstract
The aim of this cross-sectional study was to find out the role of Magnetic resonance imaging (MRI) in the assessment of time of brain insult in cerebral palsy (CP). The study was conducted in the Department of Radiology & Imaging, Mymensingh Medical College Hospital, Mymensingh and a total number of 35 patients with were enrolled from January 2015 to December 2016. Maximum patients (57.2%) were under five years followed by 34.3% were of 5 to <8 years and 8.7% were of 8 to <12 years of age and mean age was 4.7 years. Majority of the patients were male 28(80%) and female were 7(20%). Among the patients 23(65.7%) came from poor, whereas 11(31.4%) came from middle class and only one (2.9%) from rich socioeconomic group. According to gestational age of the patients, 26(74.3%) were term (≥37weeks) at delivery and rest (25.7%) were preterm (<37 weeks). Delayed cry after birth were present in 32 (80%) patients. Regarding types of cerebral palsy spastic diplegia, spastic quadriplegia, hemiplegia and extrapyramidal were found 3(8.6%), 25(71.4%), 4(11.4%) and 3(8.6%) respectively. Abnormal MRI was reported in 94.2% patients and gave clues to time of insult in 79.9% (excluding the 14.3% miscellaneous findings). The findings were mal-developments (5.7%), periventricular white matter lesions (25.7%), cortical or deep grey matter lesions (48.6%), miscellaneous (14.3%) and normal (5.7%). Brain mal-developments were more seen in term than in preterm born children (5% vs. 0%). Periventricular white matter lesions were seen significantly more in preterm than in term born children (77.8% vs. 3.9%). Cortical or deep grey matter lesions occurred significantly more in term than in preterm born children (60% vs. 20%). Based on the study it can be concluded that Magnetic Resonance Imaging (MRI) can help in the assessment of time of insult to the developing brain in cerebral palsy (CP).

Abstract
Uterine fibroids often cause symptoms of pelvic pain, pressure, and bleeding and a significant cause of morbidity for women of reproductive age. A new, Food and Drug Administration approved noninvasive treatment option is magnetic resonance guided focused ultrasound surgery, which has the potential to become a treatment of choice for selected patients. The purpose of the study was to compare and evaluate the usefulness of MRI and transabdominal ultrasonography for the diagnosis of uterine fibroids. A cross sectional study was carried out in the department of Radiology & Imaging of Mymensingh Medical College Hospital, during the period of January' 2010 to December 2011. A total number of 40 consecutive patients having suspected uterine fibroids underwent MRI and transabdominal ultrasonography and they were followed up from the admission upto the tissue diagnosis of uterine fibroids for histopathological correlation were included in this study. The test of validity of MRI and transabdominal ultrasonography in diagnosis of uterine fibroids was calculated. In the diagnosis of uterine fibroids, USG was 88.2% sensitive, 66.7% specific, 85.0% accurate, 93.8% positive predictive values and 50% negative predictive values. However MRI was 97.1% sensitive, 83.3% specific, 95.0% accurate, 97.1% positive predictive values and 83.3% negative predictive values for prediction of uterine fibroids. The study shows that the MRI is more efficient diagnostic modality than transabdominal ultrasonography in detecting uterine fibroid presence and evaluation.

Abstract
The thermodynamic temperature of the point of inflection of the melting transition of Re-C, Pt-C and Co-C eutectics has been determined to be 2747.84 ± 0.35 K, 2011.43 ± 0.18 K and 1597.39 ± 0.13 K, respectively, and the thermodynamic temperature of the freezing transition of Cu has been determined to be 1357.80 ± 0.08 K, where the ± symbol represents 95% coverage. These results are the best consensus estimates obtained from measurements made using various spectroradiometric primary thermometry techniques by nine different national metrology institutes. The good agreement between the institutes suggests that spectroradiometric thermometry techniques are sufficiently mature (at least in those institutes) to allow the direct realization of thermodynamic temperature above 1234 K (rather than the use of a temperature scale) and that metal-carbon eutectics can be used as high-temperature fixed points for thermodynamic temperature dissemination. The results directly support the developing mise en pratique for the definition of the kelvin to include direct measurement of thermodynamic temperature.

Abstract
Urethritis is one of the most important causes of morbidity and mortality in developing countries. The aim of this study was to detect common bacterial causes of urethritis in men by Gram stain, culture and multiplex PCR.185 male patients who presented at the Skin and venereal clinic of the Dhaka Medical College, Bangladesh with clinical symptoms suggestive of urethritis were enrolled in this study. Urethral discharges were tested for detection of Neisseria gonorrhoeae by Gram stain, culture and PCR. Multiplex PCR assay was done to detect DNA of Chlamydia trachomatis, Ureaplasma urealyticum and Mycoplasma genitalium. Out of 185 participants, 30.27% and 14.6% were infected by Neisseria gonorrhoeae and Chlamydia trachomatis respectively. None of the individuals was found positive for either Ureaplasma urealyticum or Mycoplasma genitalium. Among the Neisseria gonorrhoeae positive patients 27.57% were positive from Gram stain, 26.49% were culture positive, 30.27% were positive by PCR (p<0.001). 32.65% of the Neisseria gonorrhoeae isolates were penicillinase producers and 83.67% were susceptible to ceftriaxone. Considering culture as the gold standard, the sensitivity and specificity of PCR for the detection of Neisseria gonorrhoeae was 100%, and 94.85% respectively with an accuracy of 96.22%. 3.73% of the 134 smear negative and 5.15% of the 136 culture negative samples were positive by PCR. PCR was the most sensitive and rapid method for the diagnosis of urethritis. Multiplex PCR may be a useful approach to laboratory diagnosis of urethritis in men for its high sensitivity and specificity.

Abstract
Efforts have been made in Pakistan to create ethical guidelines for research and medical practice. This study explored the perceptions of and factors affecting the process of obtaining informed consent to surgery among inpatients and families at a tertiary-care hospital in Karachi. A random sample of 400 post-surgery adult patients answered a pre-tested, structured questionnaire. Overall, 233 patients (58.3%) had signed the surgery consent form themselves, while 167 relatives (41.7%) had signed on behalf of the patient. Perceived factors significantly associated with patients not signing the consent form themselves were: language used (adjusted OR = 4.6), medical terminology used (aOR = 2.7), insufficient time allocation (aOR = 3.8), cultural/traditional reasons (aOR = 1.5) and low education (aOR = 2.4). Inappropriate timing for taking consent and not being informed/asked about consent were not statistically significant factors. Health-care practitioners should encourage patients to sign the consent form themselves.

Abstract
Recirculation is an important issue in haemodialysis (HD) patients as increased percent recirculation causes decreased dialysis delivery of the patients. The purpose of the study was to determine the amount and factors of recirculation in those patients. The study was a cross sectional one carried in the Department of Nephrology, Dhaka Medical College and Hospital during October 2010 to September 2011. A total of 118 end stage renal disease patients with arterio-venous fistula who were on HD for more than 3 months were purposively selected. The degree of recirculation was measured with urea based two needle technique method. For each patient distances between arterial and venous and distances of needles from fistula and its directions were recorded. Echocardiography and A-V fistula Colour Doppler Ultrasound were also performed. The mean A-V fistula recirculation was 8.1 +/- 5.5% with a range 0-66%. The most common factors were close proximity and improper arterial and venous needles placement. No difference was observed between diabetic and non diabetic also between hypertensive and normotensive. A-V fistula recirculation is common occurrence in HD patients and the most common factors of recirculation are misplacement and close proximity of needles therefore emphasis should be given on education and training of HD staffs.

Abstract
To ensure that potential kidney donors in Bangladesh have no renal impairment, it is extremely important to have accurate methods for evaluating the glomerular filtration rate (GFR). We evaluated the performance of serum creatinine based GFR in healthy adult potential kidney donors in Bangladesh to compare GFR determined by DTPA with that determined by various prediction equations. In this study GFR in 61 healthy adult potential kidney donors were measured with 99mTc-diethylenetriamine penta-acetic acid (DTPA) renogram. We also estimated GFR using a four variable equation modification of diet in renal disease (MDRD), Cockcroft-Gault creatinine clearance (CGCrCl), Cockcroft-Gault glomerular filtration rate (CG-GFR). The mean age of study population was 34.31 +/- 9.46 years and out of them 65.6% was male. In this study mean mGFR was 85.4 +/- 14.8. Correlation of estimated GFR calculated by CG-CrCl, CG-GFR and MDRD were done with measured GFR DTPA using quartile. Kappa values were also estimated which was found to be 0.104 for (p = 0.151), 0.336 for (p = 0.001) and 0.125 for (p = 0.091) respectively. This indicates there is no association between estimated GFR calculated by CG-CrCl, CG-GFR, MDRD with measured GFR DTPA. These results show poor performance of these equations in evaluation of renal function among healthy population and also raise question regarding validity of these equations for assessment of renal function in chronic kidney disease in our population.

Abstract
BACKGROUND Learning of basic clinical skills is introduced in Years 1 and 2 of the MBBS Program; the Aga Khan University, Pakistan, through a structured Clinical Skills Teaching program. Acquisition of competence in performing these skills is assessed through use of the Objective Structured Clinical Examination (OSCE). Self-assessment is defined broadly as the involvement of learners in judging whether or not learner-identified standards have been met. OBJECTIVE Compared Year 2 students' self-assessment of clinical skills with examiners' assessment of performance in an OSCE using a standard rating scale. METHODS A self-assessment questionnaire was completed by all Year 2 students immediately after the OSCE. Students assessed their performance at three stations, using a performance rating scale. Examiners observed and evaluated the students during history-taking and physical examination using the same rating scale. RESULTS There were significant positive correlations between examiners' assessments of performance and students' self-assessed ratings in taking consent, obtaining demographic information, history of presenting problems and summarization. Significant differences were observed in pre-procedural skills, comment on prostate, liver palpation percussion and spleen percussion. CONCLUSIONS Findings highlight the strengths and weaknesses in clinical competence at the end of Year 2 and provide a direction to improve the gaps in the Clinical Skills Teaching program.

Abstract
In a hospital setting antimicrobial resistant organisms especially Methicillin resistant Staphylococcus aureus (MRSA) has emerged as an important variable influencing patients' outcome and overall resource utilisation. The present study was undertaken to find out the proportion of MRSA and other organisms and their antimicrobial resistance pattern in admitted cases with postoperative wound infections. A total of 50 wound swabs were collected irrespective of age and sex of the patients from National Institute of Traumatology and Orthopaedics Rehabilitation (NITOR). The laboratory work was performed in the department of microbiology of National Institute of Cardiovascular Diseases (NICVD). Isolation, identification and susceptibility testing was done according to the guideline of the National Committee for Clinical Laboratory Standards (NCCLS, 1998). Out of the 50 samples 34 yielded growths of which 15 had growth of single organism and 19 had mixed growth of 2 to 3 organisms. Four different types of organisms were identified. Highest percentage was Escherichia coli 55.9%, followed by Pseudomonas sp. 52.9%, Proteus sp. 38.2%, and Staphylococcus aureus 17.6%. Of the 6 isolates of S aureus 5 (83.3%) were MRSA. Therefore it can be concluded that MRSA is existing in the hospital premises of NITOR, which can endanger the life of many. This study emphasises that susceptibility testing of all clinical isolates is essential to reduce the morbidity, mortality and longer duration of hospital stay. In addition proper management of the cases can decrease the spread of multiple drug resistant organisms in the community.

Abstract
OBJECTIVES To evaluate the effect of vitamin A supplementation 24 h after delivery on breastmilk retinol concentration. METHODS Fifty low income women were randomly assigned to a single oral dose of 209 micromol of Vitamin A or none at delivery. Maternal serum and breastmilk retinol levels and infant morbidity and anthropometry were serially assessed. RESULTS Mean (95% CI) serum retinol levels increased in the supplemented mothers at 2.77 (2.3, 3.2) compared to 1.15 (0.9, 1.4) micromol/l in controls (P < 0.05) and remained at a significantly higher level of 1.59 (1.4, 1.8) micromol/l compared to 1.33 (1.8, 1.5) micromol/l in the control group (P < 0.001) up to a period of three months. Breastmilk retinol concentration was also greater at 24 h after supplementation, mean (CI) 11.34 (9.0, 13.7) micromol/l, compared to 2.95 (2.3, 3.6) micromol/l in the control group (P < 0.0001), and remained higher for the next six months at 1.06 (0.9, , 1.3) micromol/l compared to 0.73 (0.6, 0.8) micromol/l in the control group (P < 0.02). Infants of the supplemented mothers had reduced mean duration of respiratory tract infection of 3.1 (2.7, 3.5) days compared to 3.7 (3.3, 4.2) days (P < 0.03) and mean incidence of febrile illness 0.1 (0.1, 0.1) compared to control infants 0.3 (0.3, 0.3) days, (P < 0.002). CONCLUSION Vitamin A supplementation of malnourished mothers maintains higher breastmilk retinol concentration for at least six months and reduces the duration of respiratory tract infection and febrile illness in their breastfed infants.

Abstract
Little is known about the zinc content of breast milk in developing countries. Zinc content in breast milk was analyzed in 34 mothers of low socio-economic status; 17 were primiparae and 17 multiparae. Women in their 6th to 36th week of lactation provided 3 samples of breast milk at different times within a single day. The mean zinc concentration in breast milk (micrograms/ml) was 1.89 +/- 0.64 with a range from 0.17 to 4.38 micrograms/ ml. Zinc content in the morning, midday and evening samples were 2.1 +/- 0.84, 1.74 +/- 0.53, 1.84 +/- 0.69 respectively. There was significant variation between morning and midday samples (p = 0.038). Maternal age, parity, nutritional status or age of the child did not affect the zinc content of milk in the population studied.

Abstract
Faecal alpha 1 antitrypsin was measured in two groups of children with diarrhoea aged 6 months to 6 years during the acute and recovery stages of the illness. Group 1 comprised 19 children with a history of measles in the two weeks preceding admission to hospital. In this group there were six cases of Shigella species, six enterotoxigenic Escherichia coli, and five rotavirus, and two did not yield an aetiologic agent. Group 2 comprised 15 children with diarrhoea only. In this group there were five cases of Shigella species, five enterotoxigenic Escherichia coli, and five rotavirus. Children with rotavirus diarrhoea belonging to both groups showed a transient high faecal clearance of alpha 1 antitrypsin during the acute stage. Post measles cases of diarrhoea showed significantly higher faecal clearance of alpha 1 antitrypsin than group 2 subjects in both the acute and recovery stages. The faecal clearance of alpha 1 antitrypsin in both groups was significantly higher during the acute stage compared with the recovery stage. Highest faecal clearances of alpha 1 antitrypsin were observed in children with post measles shigellosis in the acute stage and they also had persistently raised concentrations, thus suggesting prolonged protein losing enteropathy.
