Recent Progress, Challenges, and Opportunities of Membrane Distillation for Heavy Metals Removal.

Water is essential for the presence of life on this earth. However, water contamination due to the presence of heavy/toxic metals is one of the serious environmental issues for living beings. Several methods have been devoted to separating or removing those heavy metals from wastewater. Among them, membrane distillation (MD) has become one of the most attractive approaches due to its higher rejection rate than processes driven by pressure, lower energy consumption than traditional distillation processes. MD has gained significant attention for removing heavy metals than other techniques like ion exchange and adsorption in the last two decades. This review provides insight knowledge to the reader and focuses on how heavy metals impact humans and the environment, sources of heavy metals, current and especially removal methods using the MD method. Moreover, recent studies, challenges, and opportunities on MD membrane modules and heavy metal removal systems are discussed. More importantly, in this review, we have identified the gaps and opportunities that are required for enhancing the MD approach and its practical suitability for heavy metal removals. MD module and system showed high performance, proving their possible applications to remove heavy metal ions in water/wastewater treatment.

Exploring the structure of pure germanophospate glasses with different concentrations probed by magic angle spinning NMR spectroscopy.

Phosphate-based glasses such as pure germanophosphate can be achieved at moderately low temperature by means of affordable chemical substances. Nowadays, they become more stimulating because they can be easily doped with alkali, transition metal ions, and rare earth oxides to afford the anticipated physical and/or chemical features for nanoscience applications. Herein, we report an experimental study dealing with the structure of pure germanophosphate glass samples of GeO 2 prepared with different concentrations ranging from 20 up to 70 mole%. 31 P magic angle spinning (MAS) nuclear magnetic resonance (NMR) spectroscopy has been employed to characterize the co-formed glasses by two different glass-forming oxides. The components of the phosphate species ( Q n ) in each sample were determined by analyzing the MAS NMR spectra. Interestingly, 31 P MAS NMR spectrum for each sample was found to be characteristic powder patterns of the middle units Q2 . Q2  unit found herein has one oxygen atom bonded towards one germanium atom (non-bridging) and the other two oxygens are bonding towards two phosphorus atoms (bridging) of phosphate group (PO4 ). The results show that Q2 split into two units, Q2 I and Q2 II, due to different shielding of the phosphorus nucleus provided by the next nearest neighbor atoms. The chemical shift is interpreted in terms of the structure of each building unit of the phosphate group. The results obtained herein shed light on the way how to explore the revealed structure of the prepared glasses for the development of supported catalysts. Indeed, owing to their high chemical/thermal stability, the co-formed germanophosphate glasses obtained may prove as useful substrates for potential nanocatalysts.

Combining morphometrics with molecular taxonomy: how different are similar foliose keratose sponges from the Australian tropics?

Sponge taxonomy can be challenging as many groups exhibit extreme morphological plasticity induced by local environmental conditions. Foliose keratose sponges of the sub-family Phyllospongiinae (Dictyoceratida, Thorectidae: Strepsichordaia, Phyllospongia and Carteriospongia) are commonly found in intertidal and subtidal habitats of the Indo-Pacific. Lacking spicules, these sponges can be difficult to differentiate due to the lack of reliable morphological characters for species delineation. We use molecular phylogenies inferred from the nuclear Internal Transcribed Spacer 2 region (ITS2) and morphometrics (19 characters; 52 character states) to identify evolutionarily significant units (ESUs; sensu Moritz) within foliose Phyllosponginiids collected from seven geographic locations across tropical eastern and Western Australia. The ITS2 topology was congruent with the tree derived from Bayesian inference of discrete morphological characters supporting expected taxonomic relationships at the genus level and the identification of five ESUs. However, phylogenies inferred from the ITS2 marker revealed multiple sequence clusters, some of which were characterised by distinct morphological features and specific geographic ranges. Our results are discussed in light of taxonomic incongruences within this study, hidden sponge diversity and the role of vicariant events in influencing present day distribution patterns.

Hierarchical settlement behaviours of coral larvae to common coralline algae.

Natural regeneration of degraded reefs relies on the recruitment of larvae to restore populations. Intervention strategies are being developed to enhance this process through aquaculture production of coral larvae and their deployment as spat. Larval settlement relies on cues associated with crustose coralline algae (CCA) that are known to induce attachment and metamorphosis. To understand processes underpinning recruitment, we tested larval settlement responses of 15 coral species, to 15 species of CCA from the Great Barrier Reef (GBR). CCA in the family Lithophyllaceae were overall the best inducer across most coral species, with Titanoderma cf. tessellatum being the most effective species that induced at least 50% settlement in 14 of the coral species (mean 81%). Taxonomic level associations were found, with species of Porolithon inducing high settlement in the genus Acropora; while a previously understudied CCA, Sporolithon sp., was a strong inducer for the Lobophyllidae. Habitat-specific associations were detected, with CCA collected from similar light environment as the coral inducing higher levels of settlement. This study revealed the intimate relationships between coral larvae and CCA and provides optimal coral-algal species pairings that could be utilized to increase the success of larval settlement to generate healthy spat for reef restoration.

Efficacy of topical application of Pimecrolimus cream in the treatment of discoid lupus erythematosus.

The interventional type of study to assess the efficacy of Pimecrolimus cream in the treatment of patient of localized discoid lupus erythematosus (DLE) was carried out for a period of July 2008 to June 2009. It was observed that before treatment, erythema was severe in 43.2% cases, moderate in 51.4% cases and mild type erythema was present in 5.4% cases. The post- treatment revealed, 29.7% severe type erythema, none evidenced moderate type erythema, only 43.2% had mild type and 27% cases no erythema at all. Before treatment, infiltration was severe in 27% cases, moderate in 54.1% cases and only 18.9% had mild type infiltration. But after treatment, 10.8% had severe type infiltration, 18.9% had moderate, 51.4% had mild and 18.9% had no infiltration at all. Similar response to treatment was noticed with squamation which exhibited a drop from 37.8% to 18.9% in severe cases and from 62.2% to 10.8% in moderate cases. There was a 45.9% mild case and 24.3% had no squamation. The scoring result of photosensitivity, itching, disfigurement evidenced analogously score reduction of 2.0, 3.05 and 3.12 respectively. In conclusion, it was interpreted that score of patients of DLE, before treatment was 6.83 ± 1.30 and after treatment was 3.83 ± 1.18. Unpaired 't' test was found statistically significant (p<0.05) between before and after treatment by drug. Improvement was shown in 26(70.27%) cases and 11(29.73%) cases shown no improvement at all. Marked improvement observed on the 2nd follow up visit at the end of 12 weeks. Response was good in 23(88.46%) cases, fair 2(7.69%) and poor 1(3.85%) cases. The study suggests that pimecrolimus 1% cream has significant efficacy profile for treatment option of cutaneous lupus erythematosus.

Nonspirometric aspects of pulmonary function in subjects with dust industries.

Bangladesh is a developing country. Many workers are involved in different industries which are polluted with dust e.g. saw mill, rice mill, jarda factory etc. The present study may give a preliminary idea about the lung function status of those workers. The study has been designed to analyze the lung function status of those workers by measuring TCO2 aiming to recommend necessary steps to improved the quality of life of workers of dust industry in our socioeconomic context. This study was to evaluate pulmonary functional status of those workers who are exposed to dust in industries like saw mill 26.00 mmol/l, rice mill 31.10 mmol/l and jarda factory 22.11 mmol/l. In all groups p values were >0.1 which was not significant except jarda factory worker in which p value was <0.001 and it was highly significant. This study was carried out to increase the awareness of the workers and to reduce the cost of employment.

Minor criteria for atopic dermatitis in children.

Atopic dermatitis (AD) is a common pruritic, eczematous skin disorder that runs a chronic and relapsing course. Major and minor criteria exist as guideline for arriving at a diagnosis of AD. Minor features vary with ethnicity and genetic background and can be used to aid diagnosis. A descriptive study was conducted including 210 patients of 1-12 years age who had concurrent or past history of AD according to criteria of Hanifin and Rajka. This study was conducted in the department of Dermatology of three different Hospitals of Bangladesh. Out of 33 sub-criteria of Hanifin and Rajka, 20 of which were examined encompassed tendency towards cutaneous infection, environmental factor, high IgE level, intolerance of wool, xerosis, infra-orbital fold, ichthyosis, early age of onset, itch on sweating, palmer hyperlinearity, food hypersensitivity, keratosis pilaris, pityriasis alba, facial erythema, cheilitis, hand eczema, foot eczema, intolerance of lipid solvent, scalp scaling and infra-auricular fissure. Out of 20 examined minor criteria, most common was cutaneous infection in 168(80.0%) patients followed by coursed influenced by environmental factor in 140(66.7%), high IgE level in 126(60.0%), intolerance of wool in 105(50.0%), xerosis in 92(43.8%), infra-orbital fold in 83(39.5%), ichthyosis in 72(34.3%), early age of onset in 65(31.0%), itch on sweating in 56(26.7%), palmary hyperlinearity in 52(24.8%), food hypersensitivity in 40(19.0%), keratosis pilaris in 31(14.8%), pityriasis alba in 30(14.3%), facial erythema in 25(1.9%), cheilitis in 22(10.5%), hand eczema in 19(9.0%), foot eczema in 16(7.6%), intolerance of lipid solvent in 14(6.7% ), scalp scaling in 11(5.2%) and infra-auricular fissure in 10(4.8%). These features were present singly or in combination. The result evidenced that minor criteria are many a times important for the diagnosis where major criteria are uncertain.

Prevalence and Pattern of Dyslipidemia in Diabetes Mellitus Patients Admitted in the Department of Cardiology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh.

Patients with Diabetes Mellitus are at high risk of cardiovascular events because of abnormal lipid metabolism. Dyslipidemia is common in patients with Diabetes Mellitus (DM). However; in Bangladesh this issue is not yet properly addressed. The aim of this study is to determine the prevalence and patterns of dyslipidaemia in patients with DM in a divisional city Mymensingh. This cross-sectional study was conducted in randomly selected eligible patients from the indoor registry of the Department of Cardiology, Mymensingh Medical College Hospital (MMCH), Bangladesh from April 2012 to March 2013. A well structured questionnaire and blood investigation for lipid profile and blood sugar were the tools of data collection from 120 randomly selected DM patients registered in the department of cardiology, MMCH. Out of 120 enrolled participants the prevalence of dyslipidemia in DM patients was 86.0%, prevalence of dyslipidemia in males was 88.0% while in females was 85.0% but the difference was not significant (p=0.42). Regarding age group, BMI and duration of DM, there is no significant association exists with dyslipidemia. About half of the studied DM patients have high serum total cholesterol level (50.83%), while 22.5% had low serum HDL-C levels and 35.0% had high serum LDC-C level, most of patients had serum triglyceride levels above normal range (67.5%) and so the common patterns of dyslipidemia in this study were serum triglyceride level followed by total cholesterol. High prevalence of dyslipidemia among diabetes mellitus in Mymensingh city were observed and so the common patterns of dyslipidemia is triglyceride followed by total cholesterol. This study emphasizes the importance of screening of lipid profile as these abnormalities may lead to development of cardiovascular diseases.

Profile of lichen planus in Bangladesh.

Lichen planus is one of the common inflammatory disorders of skin, mucous membrane, nail and hair characterized by violaceous, polish, pruritic, polygonal, flat-topped papules usually distributed bilaterally symmetrically over the extremities. Our objectives in this study were to explore the prevalence of lichen planus in large area of Dhaka in Bangladesh and to establish the clinical characteristics of lichen planus. This descriptive type of cross sectional study was carried out from September 2006 to August 2008 in the Department of Dermatology and Venereology of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka Medical College Hospital (DMCH) and Combined Military Hospital (CMH) in Dhaka. Patients suffering from lichen planus were selected as study population. By face to face interview and clinical observations, data were collected from sample. A total 120 patients of lichen planus were selected, on the basis of age, 30(25%) were 10-30 years of age, 75(62.56%) were 30-50 years and 16(13.33%) were over 50 years of age. The mean age of the patient was 40+/-4 years. Out of 120 patients, 80(66.66%) were male and 60(33.33%) were female and eight patients (6.67%) had positive family history among highest age group (30 to 50 years). In case of duration of disease, highest percentage (68%) of cases was 15 days to 6 months and considering clinical sign, koebnerization was present 45(37.5%) cases and Wickhams striae 22(18.33%) cases. Regarding site of onset of lesion, lesions were highest 100(83.33%) in upper limbs, next lower limbs, trunk, oral mucosa etc. The distribution of clinical pattern of lichen planus showing classic pattern (68.33%) was the most common type, followed by hypertrophic, actinic, ashy dermatoses, lichen plano-pilaris, erosive or ulcerative etc. This clinico-epidemiological study of lichen planus attending in the different hospital in Dhaka, Bangladesh has shown that lichen planus is usually associated with 30 to 50 years of age group, with higher male prevalence than female, 15 days to 6 months are mainly duration of disease, koebnerization and Wickhams striae are common clinical signs, upper limbs is mainly the site of onset of lesion, and classic pattern is the most common clinical type in lichen planus.

Various factors of attempted suicide in a selected area of Naogaon district.

This descriptive type of study was carried out to determine the various factors of attempted suicide in a selected area at Patnitala and Dhamuirhat upazilla health complex of Naogaon district. All reported alive cases of attempted suicide (self poisoning, hanging, self burning or immolation, drowning etc) during the period from March to June 2003 were interviewed purposely. Data were collected by face to face interview and also from hospital records. Of the interviewed cases, the mean age was 21.4 years. Household workers, day labours, students and agricultural workers (42.6%, 23.9%, 15.5% and 11.3% respectively) were the major victims and nearly 60% had nuclear family. The highest number (77.5%) used organophosphorus compound. Highest number (25.4%) mentioned that husband mainly provoked for suicidal attempt, followed by mother and father. It was evident that 71.8% of suicidal attempt was due to their emotional stress, followed by family violence, disturbed family, social deprivation, stressful events and health problems (50.7%, 49.3%, 36.6%, 25.4%, and 8.5% respectively). It was evident that attempted suicide is proportionately higher among adolescents of unmarried, with early age at marriage, with higher income and with nuclear family compared with adult. Emotional stress, disturbed family, social deprivation, health related problems are appeared to be important reasons for attempted suicide among adolescents whereas family violence in adults.

Single dose (400 mg) versus 7 day (200 mg) daily dose itraconazole in the treatment of tinea versicolor: a randomized clinical trial.

Tinea (pityriasis) versicolor is a superficial fungal infection and one of the most commonly found pigmentary disorders of skin caused by the yeast Malassezia. Multiple topical as well as systemic therapies are available for treatment. Systemic therapies are used for extensive disease, frequent relapse or where topical agents have failed. The aim that translates the rationale of the study was to compare the efficacy, safety, tolerability and cost effectiveness of single dose 400mg versus 7 day 200 mg daily dose of itraconazole in the treatment of tinea versicolor. A clinical study was done to compare the efficacy of single dose (400 mg) of itraconazole and 7 day 200 mg daily dose of itraconazole in the treatment of extensive tinea versicolor. Total 60 patients (aged 18-50 years) were selected for the study during the period of June 2007 to May 2008 in the department of Dermatology of three different hospitals in Bangladesh. Cases having with extensive involvement, diagnosed clinically and confirmed by wood's lamp and KOH microscopy were taken. Patients were randomly allocated into equal groups. Group A was given single dose 400 mg itraconazole and Group B was given 7 day 200 mg daily itraconazole. Fifty three (88%) male and 7(12%) female were included in the study. The mean age of group A was 32.37+/-9 years and in group B 33.23+/-8 years. The mean duration of the disease in group A was 2.63+/-2 months and 2.76+/-2 months in group B. In group A clinical responders was found cure 22(73.33%) and improvement 5(16.33%) and in group B it was found cure 24(79.99%) and improvement 4(13.33%). The measure at the End point (EP1) equals to 90% response and in-group B it was found cure 24 (79.99%) and improvement 4(13.33%). (Here the End point EP2) equals to 93.33%. The EP clinical analysis however shows 91.66% response. Both single dose and 7 day daily dose of itraconazole can be effective in the treatment of tinea versicolor with extensive involvement but single dose appears to be better for improving compliance and decreasing the cost of treatment.

Efficacy of Itraconazole in the Prevention of Recurrence of Tinea Versicolor: A Three Year Follow Up.

Pityriasis versicolor (PV) also known as tinea versicolor, which is chronic and superficial fungal skin disease caused by Malassezia yeasts. A permanent cure may difficult to achieve and this may explain the long-term nature of the disease. Consequently, a preventive treatment regimen may help to prevent the recurrence of pityriasis versicolor. Whether, the recurrence of tinea versicolor could be prevented by monthly itraconazole treatment regimen after a short course of itraconazole therapy. Open treatment followed by a randomized, single blind placebo control trial. Multi-center trial was characterized by an open, active treatment phase with itraconazole followed by a randomized placebo controlled treatment for prevention of recurrence. A total 200 patients (150 male and 50 female) were included in this study and was given 200mg itraconazole daily for 7 days (treatment phase). Patients in whom tinea versicolor was mycologically cured divided into Group A and Group B. Active open treatment was followed by preventive itraconazole treatment 200mg twice daily in Group A and placebo in Group B monthly for 6 consecutive months. The patients were diagnosed clinically and confirmed by Wood's lamp examination and KOH microscopy. Clinical improvement in 90%, negative Wood's lamp examination in 86.5% and Mycological cure in 85.5% were found at the end of open treatment. The mycological cure, 171 subjects were taken into this study for preventive treatment phase and divided into two groups- Group A & Group B. Preventive treatment was given in Group A and placebo in Group B. After the preventive treatment, the end point (After 6 months), clinical improvement, negative Wood's lamp examination and mycological cure were found in 81(90%), 76(84.4%) and 75(83.3%) in Group A and 44(55%), 41(51.3%) and 42(52.5%) in Group B respectively. In preventive treatment phase, 1 patient in Group A did not complete the study. No patient experienced any serious adverse effects. Prevention of recurrence of Pityriasis versicolor with itraconazole is as effective as treatment.

Genetic variation in strains of zebrafish (Danio rerio) and the implications for ecotoxicology studies.

There is substantial evidence that genetic variation, at both the level of the individual and population, has a significant effect on behaviour, fitness and response to toxicants. Using DNA microsatellites, we examined the genetic variation in samples of several commonly used laboratory strains of zebrafish, Danio rerio, a model species in toxicological studies. We compared the genetic variation to that found in a sample of wild fish from Bangladesh. Our findings show that the wild fish were significantly more variable than the laboratory strains for several measures of genetic variability, including allelic richness and expected heterozygosity. This lack of variation should be given due consideration for any study which attempts to extrapolate the results of ecotoxicological laboratory tests to wild populations.

Serum Albumin Level and In-Hospital Outcome of Patients with First Attack Acute Myocardial Infarction.

Acute myocardial infarction (AMI) patients constitute a large proportion of admissions in coronary care unit and their management and risk stratification is of immense importance. A decrease in serum albumin concentration might be associated with an increased risk in the incident of both cardiovascular diseases and worse hospital outcome. We assessed whether serum albumin levels at admission was associated with in-hospital adverse outcome in patients with first attack of acute myocardial infarction (AMI). The aim of the study was to evaluate association of serum albumin level with in-hospital outcome in patients with first attack of acute myocardial infarction. This cross-sectional analytical study was conducted in the department of cardiology in Mymensingh Medical College Hospital, Mymensingh, Bangladesh from March 2017 to February 2018. Total 374 patients of first attack of acute myocardial infarction included considering inclusion and exclusion criteria. The sample population was divided into two groups: Group I (Patients with acute myocardial infarction with serum albumin <3.5gm/dl) and. Group II (Patients with acute myocardial infarction with serum albumin ≥3.5gm/dl). Serum albumin level was measured within 24 hours of admission and the incidence of in-hospital major cardiac outcomes was observed. In this study mean±SD serum albumin level of Group I, Group II were 3.02±0.12gm/dl, 4.48±0.50gm/dl respectively. In Group I patient, 52(59.80%), 7(8.00%), 10(11.50%), developed heart failure, cardiogenic shock, arrhythmias respectively and 8(9.20%) died and in Group II patient 20(7.90%), 7(2.80%), 8(3.20%) developed heart failure, cardiogenic shock, arrhythmias respectively and 4(1.60%) died out of them and all of these outcome were statistically significant. Mean±SD duration of hospital stay of the study population according serum albumin level, in Group I, 5.76±1.83 days, in Group II, 4.40±1.22 days which was statistically significant (p<0.05). In conclusion, patient with first attack of acute myocardial infarction serum albumin level below 3.50gm/dl increased the risk of worse in-hospital outcome.

Elevated chromosome translocation frequencies in New Zealand nuclear test veterans.

In 1957/58 the British Government conducted a series of nuclear tests in the mid-Pacific codenamed Operation Grapple, which involved several naval vessels from Britain and New Zealand. Two New Zealand frigates with 551 personnel onboard were stationed at various distances between 20 and 150 nautical miles from ground zero. In the present study we applied the cytomolecular technique mFISH (multicolour fluorescent in situ hybridisation) to investigate a potential link between chromosome abnormalities and possible past radiation exposure in New Zealand nuclear test veterans who participated in Operation Grapple. Compared to age matched controls, the veterans showed significantly higher (P < 0.0001) frequencies of chromosomal abnormalities (275 translocations and 12 dicentrics in 9,360 cells vs. 96 translocations and 1 dicentric in 9,548 cells in the controls), in addition to a significant excess of CCRs (complex chromosomal rearrangements) in the veterans. A Kolmogorov-Smirnoff test showed that the distributions of translocations for the two groups were significantly different.

Predictive Factors of Liver Dysfunction After Right Hemihepatectomy for Adult Living Donor Liver Transplantation.

BACKGROUND: Living liver donors represent a special group of patients. They are healthy individuals who are exposed to a major surgery, in which the dominant liver proportion is extracted as a graft. Of all potential donor-related morbidities, posthepatectomy liver dysfunction (PHLD) is the most significant as it may be directly related to donor mortality. We aimed to review our data of adult living donor liver transplantation (LDLT) utilizing the right hemiliver grafts to determine the incidence and potential predictors for the development of PHLD, defined according to the International Study Group of Liver Surgery. METHODS: We reviewed the data of all adult living donors who underwent right hemihepatectomy during the period between May 2004 and 2016. RESULTS: During the study period, 434 cases underwent right hemihepatectomy for adult LDLT. We divided our cases into 2 groups according to the occurrence of PHLD. A significant lower residual liver volume and percentage were noted in PHLD group. Longer intensive care unit stay and hospital stay, and more postoperative morbidities, were observed in PHLD group. PHLD occurred in 50 cases (11.5%), and most of them were grade A (47 cases [10.8%]). Two cases (0.5%) had grade B requiring diuretic therapy, and 1 case (0.2%) had grade C requiring ultrasound guided tube drainage and surgical exploration finally. CONCLUSIONS: We should not underestimate the risks of liver donation surgery, especially when utilizing the right hemiliver graft. Donor safety should be ensured by accurate preoperative volumetric assessment of the remnant liver and remnant liver volume limitations must be strictly followed.

Living-Donor Liver Transplantation in Hepatitis C Virus Era: A Report of 500 Consecutive Cases in a Single Center.

BACKGROUND: Living donor liver transplantation (LDLT) is considered a safe alternative to deceased donor liver transplantation (DDLT). In Egypt, DDLT program is still awaited, making LDLT the only hope for patients with end-stage liver disease, mainly due to chronic hepatitis C virus (HCV) infection. The current study is conducted to evaluate our experience of LDLT and discuss the lessons learned from 500 consecutive cases in HCV area. METHODS: We reviewed the data of patients who underwent LDLT at Gastrointestinal Surgery Center, Mansoura University during the period between May 2004 and March 2017. RESULTS: During the study period, 500 cases underwent LDLT at our unit. The median age was 51 years, and most of our cases were males (446, 89.2%) and had HCV infection (453, 90.6%). The median MELD score was 15. Median ICU stay was 5 days, and hospital stay was 22 days. Postoperative morbidities occurred in 220 cases (44%). Early mortality occurred in 69 patients (13.8%), and late mortality occurred in 45 patients (9%). The 1-, 3-, 5-, and 7-year overall survival rates of all cases were 80.9%, 78.2%, 75.7%, and 75%, respectively. Preoperative creatinine, worm ischemia, blood transfusion, ICU stay, postoperative morbidities, and small for size syndrome were independent predictors for overall survival. CONCLUSIONS: In countries lacking DDLT, LDLT is the only effective alternative. LDLT requires a teamwork to achieve successful outcomes. LDLT should only be performed in centers with the adequate experience to avoid and decrease the hazards related to this procedure.

Efficacy of combination therapy for the management regime of Alopecia areata.

Alopecia areata is a world wide cosmetic problem. Cases are seen in Bangladesh. Due to financial constraint and lack of modern facilities the patients of this country needs cheap, easily available and conveniently usable treatment modality. The present study revealed that the oral administration of prednisolone for 06 weeks followed by topical application of 02% minoxidil for another period of 14 weeks is noninvasive and could act as better remedy for alopecia areata. It is claimed that steroid could induce hair growth through immunosuppression rather than a direct effect on hair growth promotion. When applied together steroid it induced regrowing hair gave more encouraging result. The combination therapy indicated that the gradual loss of hair could be minimized and regrowth of hair could be made possible. To fulfill the demand for the best compliance of treatment modality further study should be directed and dictated amongst a large group of population.

Role of cardiac troponin I in staging and prognosis of congestive heart failure subjects.

Congestive heart failure is the one of the major cardiovascular disorder that is increasing in incidence and cause of death globally. Mortality rate has increased 40%-50% in advanced cardiac failure and 15%-25% in mild to moderate cardiac failure within one year of diagnosis. There is no established biochemical marker for the diagnosis, prognosis and staging of heart failure. Cardiac Troponin I may be a novel useful tool in identifying patients with Heart failure who are at increased risk for progressive ventricular dysfunction and death. Thirty six congestive heart failure cases and thirty six healthy controls were included in this study and serum cardiac troponin I and Ejection fraction were measured. All the study subjects were grouped according to the NYHA class they belong. Cardiac troponin I was significantly higher in CHF cases than the controls. Troponin I also significantly differed among groups. EF of cases was significantly lower than the controls and also differed among groups. A significant negative correlation between cardiac troponin I and progressive decline of ejection fraction was evident in this study. Cardiac troponin I increased progressively with progression of heart failure. Thus, Cardiac troponin I could be used to stratify patients undergoing heart failure in to high and low risk groups for future cardiac events. Cardiac troponin I could also be used as a very important marker for the prognosis of the patients with congestive heart failure.

Spot morning urine protein creatinine ratio and 24 hour urinary total protein excretion rate.

Proteinuria helps to establish the diagnosis of most renal diseases and also to predict the outcome of such diseases. Proteinuria is biochemically represented by measuring the protein concentration in timed collection of 24 hour urine. But, 24-hour timed urine collection is time consuming, cumbersome and often unreliable due to collection errors and also results in undue delay on diagnostic process. An alternate approach avoiding arduous and inaccurate timed urine collection can be the measurement of protein creatinine ratio in spot morning urine. This study was aimed to evaluate whether the spot morning urine protein creatinine ratio can be a reliable alternative to 24-hour urinary total protein (UTP) estimation. The study was carried out in the department of Biochemistry, Bangabandhu Sheikh Mujib Medical University, Dhaka on 50 (fifty) non-diabetic Chronic Renal Disease (CRD) patients with an age ranging from 18 -70 years. The study subjects were grouped into mild, moderate and severe CRD on the basis of GFR. Urinary protein and creatinine concentrations were measured in spot morning urine samples and their ratios were calculated. Urinary protein measured in 24-hour timed collected urine samples gave the 24-hour UTP excretion rate. In our study, spot morning urine protein creatinine ratio significantly correlated with 24-hour UTP excretion rate in all CRD patients. Severe CRD patients gave significant positive correlation (p<0.05), whereas mild and moderate CRD patients gave very highly significant positive correlation (p<0.001). Therefore, it may be suggested that protein creatinine ratio in spot morning urine can be accepted as a reliable and alternative to 24-hour UTP excretion rate in non-diabetic chronic renal disease patients. This simple and inexpensive procedure will thus simplify the way of establishing the severity of renal disease along with its prognosis.
