Therapeutic effects of functional electrical stimulation on motor cortex in children with spastic Cerebral Palsy

In the present study we have evaluated the electroencephalogram (EEG) signal recorded during ankle dorsal and plantar flexion in children with spastic Cerebral Palsy (CP) after Functional Electrical Stimulation (FES) of the Tibialis Anterior (TA) muscles. The intervention group had 10 children with spastic diaplegic/hemiplegic CP within the age group of 5 to 14 years of age who received both FES for 30 minutes and the conventional physiotherapy for 30 minutes a day, while the control group had 5 children who received only conventional physiotherapy for 60(30 + 30) minutes a day only. Both group were treated for 5 days a week, up to 12 weeks. The EEG data were analyzed for Peak Alpha Frequency (PAF), sensorimotor rhythm (SMR), mu wave suppression and power spectral density (PSD) of all the bands. The results showed a decrease in SMR and mu wave suppression in the intervention group as compared to the control group, indicating a positive/greater improvement in performance of motor activities. Therefore, from this study we could conclude that FES combined with conventional physiotherapy improves the motor activity in children with spastic CP.

A novel fibrinogen γ chain frameshift deletion (c.637delT) in a patient with hypodysfibrinogenemia associated with thrombosis

Inherited fibrinogen (FG) disorders are rare and result in quantitative or/and qualitative FG deficiency. While the majority of patients with clinically relevant FG deficiencies demonstrate a bleeding phenotype, a subset of patients are at increased risk of thrombosis.

PATIENTS AND METHODS

We report a 54-years old man presenting with a thrombophilic phenotype characterized by two episodes of unprovoked venous thrombosis and a deep vein thrombosis several weeks after myocardial infarction. Recently, he developed A. carotis communis thrombosis and died. Coagulation tests were done using standard procedures. FG genes were screened using direct sequencing. Effect on fibrin clot structure was analyzed by scanning electron microscopy (SEM) and FG chain polymerization was analysed using SDS-PAGE.

RESULTS

While thrombophilia testing was negative, we found a decreased concentration of clottable FG (126-148 mg/dl) compared to FG antigen (182-194 mg/dl of normal). The thrombin time was slightly prolonged, while aPTT and reptilase time were within the normal range. A novel deletion in FGG gene (c.637delT) resulting in a frameshift and the premature termination of the γ chain at amino acid position p.228 was identified. SDS-PAGE showed a time-shift in γ-γ and α-α cross linking. SEM showed no statistically significant differences between the patient´s and a healthy control´s fibrin clot structure.

CONCLUSIONS

In addition to the reduction of FG concentration expected by the nature of the mutation also a functional defect (hypodysfibrinogenemia) was found. Moreover this mutation seems to increase the risk of thrombosis warranting long term anticoagulation possibly in a combination with antiplatelet drugs.

Neoplasm-induced bleeding in inherited, heterozygous FXIII-A deficiency

Inherited mild factor XIII deficiency belongs to one of the most underdiagnosed bleeding disorders so far. This is, because most patients do not develop bleeding complications in daily life.

A man (age: 64 years) without a history of bleeding presented with painful swelling of neck, weight loss, anemia and episodic bleeding from the right tonsil necessitating tonsillectomy. Histologic and immunohistochemical evaluation revealed cytokeratinpositive epitheloid angiosarcoma. Blood coagulation status showed significantly elevated D-dimer and decreased FXIII levels (FXIII-activity 35%, FXIIIA-Ag 16–26%). Plasma mixing studies excluded neutralizing antibodies against FXIII.

A novel heterozygous F13A1 gene nonsense mutation (p.Glu103Ter, c.307G>T) was found confirming heterozygous FXIII-A deficiency. The same mutation was detected in two further asymptomatic relatives. For further clinical management the patient was transfused with FXIII-concentrate and showed an adequate increase of FXIII ruling out FXIII deficiency to be induced by increased turnover. Despite this haemostatic management and antifibrinolytic treatment the patient had to undergo several revisions due to delayed, Hb relevant bleeding after cervical lymph nodes extirpation and resection of tonsil. Two chemotherapy cycles with paclitaxel and palliative radiotherapy of the neck area were performed, but the patient died unfortunately two months after diagnosis.

It is a unique case showing the combination of a highly aggressive angiosarcoma and presence of inherited FXIII deficiency. It is also a rare example demonstrating the benefit of FXIII genotyping besides the expected acquired FXIII deficiency possibly due to neoplasm induced increased consumption by elevated crosslinking of fibrin fibers.

Novel point mutation in fibrinogen (Innsbruck; BβArg44Gly). Phenotypic differences compared to another mutation (fibrinogen Nijmegen) at the same position

This is a report of a novel fibrinogen point mutation (fibrinogen Innsbruck), a C/G point mutation at position 220 of exon two of the fibrinogen Bβ-chain leading to BβArg44Gly. The heterozygous mutation was found in a 16-year-old adolescent, hospitalized for the management of juvenile depression, who suffered from multiple epistaxis episodes during his stay at the university hospital in Innsbruck, Austria. Fibrinogen (based on the Clauss method) and fibrinogen antigen levels were highly discrepant (86 vs. 223 mg/dl) with thrombin time and reptilase time being in the respective upper reference ranges. Densitometric analysis of electrophoretic band pattern showed a reduction of α-polymers, indicating an impaired fibrin polymerization. This is in agreement with structural analysis, which showed a disturbance of the flexibility and structure of the region surrounding the fibrinoeptide B cleavage site. Fibrinogen Nijmegen, a mutation at the same position, is causative for thrombosis, whereas fibrinogen Innsbruck appears to lead to a bleeding tendency, illustrating that even mutations at the same position can cause contrary symptoms.

Prevention of Parastomal Hernia Using Pre-peritoneal Mesh - Long Term Outcome of a Prospective Study

BACKGROUND

Parastomal hernia is a frequent complication after stoma formation. The objective of this prospective study was to find long-term outcome of prophylactic mesh placement in the pre-peritoneal space in order to prevent parastomal hernia.

METHODS

Patients undergoing elective formation of permanent stoma were included in the study. A polypropylene mesh was placed in the pre-peritoneal space without any anchoring stitches and bowel was taken out through a central circular hole made in the mesh. These patients were followed up for 5 years-by clinical examination and CT scan when needed.

RESULTS

A total of 42 patients were included in the study. These patients were followed up for a median period of 60 months (range 32-100 months). Twelve patients died before the 5-year follow up due to causes unrelated to stoma. As two patients were unable to be contacted, 28 patients remained in the long-term follow up. Three cases of parastomal hernia were detected after 5 years. None of these patients required repairing of the parastomal hernia. However, a previous study conducted 3 years ago found 4 cases of parastomal hernia that was treated by resiting the stomas. Therefore the total number of parastomal hernia detected in our series is 7 (incidence 25%).

CONCLUSION

Putting a pre-peritoneal polypropylene mesh is an easy, quick and inexpensive method, and easy to learn. The outcome is better than creating stomas without mesh, but further studies are needed to explore potential benefits of different types of mesh and their methods of positioning and anchoring.

Assessment of stigma associated with tuberculosis in Mexico

BACKGROUND

Stigma is a major barrier to health care access and impacts the quality of life for individuals affected by tuberculosis (TB). Assessing TB stigma is essential to addressing health disparities. However, no such instrument was available in Mexico at the time of our study. This study examined the adaptability of the TB and human immunodeficiency virus (HIV) stigma scales previously used in Thailand.

METHODS

The original scale, developed in English, was linguistically adapted to Spanish and administered to 217 individuals affected by TB in five states in Mexico. The TB-HIV stigma subscales were designed to assess individual and community perspectives. Additional data collected included general information and socio-demographics. Assessment of psychometric properties included basic statistical tests, evaluation of Cronbach's alpha and factor analysis.

RESULTS

We found no significant statistical differences associated with higher stigma scores by location, age, marital status, education and stigma scores. Factor analysis did not create any new factors. Internal consistency reliability coefficients were satisfactory (Cronbach α = 0.876-0.912).

CONCLUSION

The use of the stigma scales has implications for 1) health improvements, 2) research on stigma and health disparities, and 3) TB and HIV stigma interventions. Further research is needed to examine transferability among larger and randomly selected Spanish-speaking populations.

A novel nested reverse-transcriptase polymerase chain reaction method for rapid hepatitis C virus detection and genotyping

PURPOSE

Rapid and specific detection of viral nucleic acid is increasingly important in the diagnosis of infectious diseases. The objective was to develop a rapid, efficient process of nucleic acid based detection of hepatitis C virus (HCV) infection for its diagnosis and treatment follow-up.

MATERIALS AND METHODS

A two-step nested reverse-transcriptase polymerase chain reaction (RT-PCR) has been standardised on a sample set of 125 individuals from different liver clinics in Kolkata. The method utilises a novel fast nested RT-PCR for HCV detection and genotyping from HCV infected patient plasma with high processivity.

RESULTS

The overall time required from ribonucleic acid (RNA) isolation to nested PCR amplified product detection is reduced to 42% when compared with conventional nested RT-PCR amplification. The method is sensitive as conventional PCR and detected all HCV RNA positive samples. Sequencing, phylogenetic analysis of the PCR amplified product by this method showed concordant genotypes with conventional PCR.

CONCLUSION

Though being a two-step process, this method is fast, cost-efficient, reliable and feasible for regular HCV RNA screening and apt even in resource limited settings. This method could be translated to regular nucleic acid screening for other infectious diseases as regular PCR regimen.

Design and development of an in-line sputtering system and process development of thin film multilayer neutron supermirrors

Neutron supermirrors and supermirror polarizers are thin film multilayer based devices which are used for reflecting and polarizing neutrons in various neutron based experiments. In the present communication, the in-house development of a 9 m long in-line dc sputtering system has been described which is suitable for deposition of neutron supermirrors on large size (1500 mm × 150 mm) substrates and in large numbers. The optimisation process of deposition of Co and Ti thin film, Co/Ti periodic multilayers, and a-periodic supermirrors have also been described. The system has been used to deposit thin film multilayer supermirror polarizers which show high reflectivity up to a reasonably large critical wavevector transfer of ∼0.06 Å(-1) (corresponding to m = 2.5, i.e., 2.5 times critical wavevector transfer of natural Ni). The computer code for designing these supermirrors has also been developed in-house.

Cause of and contributing factors to maternal deaths; a cross-sectional study using verbal autopsy in four districts in Bangladesh

Verbal autopsy used at community level is an accepted method to identify cause of death and factors contributing to death. Maternal deaths occurring in four districts in Bangladesh over a period of 24 months were identified and community health workers were trained to conduct a verbal autopsy. Of 571 maternal deaths identified almost half (273, 47.8%) occurred at facility level, 97 (17.0%) died en route to a healthcare facility and 201 (35.2%) maternal deaths occurred at home. The majority of maternal deaths occurred in the postpartum period (78.8%) in the first 6 hours after giving birth (41.6% of all postpartum deaths). Women who had accessed care at a healthcare facility were less likely to die in the first 6 hours when compared with women who died at home (relative risk 0.70; 95% confidence interval 0.56-0.88) 70.4% (402) of deaths were classified as direct maternal deaths, 12.4% (71) as indirect and 13.8% (79) as unspecified. The most common cause of death was haemorrhage (38%), followed by eclampsia (20%) and sepsis (8.1%). Almost three out of four women who died had sought care for complications during the index pregnancy. Most mothers who died in Bangladesh had accessed care. It is now crucial that the quality of care received at health facility level is improved. This includes a refocus on strengthening healthcare providers' knowledge and skills to recognise and manage complications and provide emergency obstetric care. The enabling environment must be in place as well as ensuring a fully functional referral pathway between healthcare facilities.

The many faces of Pulmonary Langerhans Cell Histiocytosis

Langerhans Cell Histiocytosis is a rare disease with variable presentation and prognosis in adults and in children. Histiocytosis of the ocular choroidal tissue has never been reported before in adults. We present two cases, one with choroidal involvement with asymptomatic nodulo-cystic changes in the lungs and another case with advanced single organ pulmonary involvement. We discuss the various treatment modalities and highlight the lack of adequate guidelines to treat adults. Most of the current guidelines are based on evidence derived from pediatric literature. We would also like to draw attention to the asymptomatic nature of the lung involvement and suggest that imaging of the lung be obtained in all cases of Langerhans Cell Histiocytosis.

Service satisfaction in E_Electricity service in Odisha (a state of India) by structural equation modeling

Purpose

– The purpose of this paper is to develop a new model, namely service quality measurement for E_Electricity utility service in Odisha a state of India for the measurement of service quality.

Design/methodology/approach

– Service quality regulation is an important and timely issue in many industries. The question of governance of power sector is an important question before researchers, policy makers and administrators for the obvious reason of its being an important input for socio-economic development of a nation. Power sector involves complex activities like generation, transmission, distribution and final delivery of service to end-users, i.e. consumers. Initially, private sector was the main player in the power sector when the electricity came to be used in India during the pre-independence period. The trajectory of power industry, from its inception to the present, has been complex rather than being simplistic for the reason that the pendulum of industry's ownership and regulation swings between privatization and nationalization. The consumers are main sufferer in this type of situation, and the satisfaction level decreases day by day. So government has changed it's strategies by implementing e-governance to electricity sector for achieving maximum consumer satisfaction. The first step to e-governance is change management within the government, enhancing citizens' access to information and improving government-to-citizen (G2C) interactions. This work seeks to propose a theoretical scale to measure e-government service quality and validate the measured instrument for electricity utility service by structural equation modeling.

Findings

– The results indicate that basically the E_electricity service has a positive and direct influence on dimensions (web site design, fulfillment, privatisation and information).

Research limitations/implications

– Only Odisha state is considered for measuring online service quality in electricity utility service.

Originality/value

– As the electricity utility industry is doing monopoly business in India and all states basically in Odisha due to that the customer dissatisfaction is the most important obstacle. So the policy makers must concentrate on the dimensions and the sub-dimension before regulating new policies.

A preliminary report on the genetic variation in pointed gourd (Trichosanthes dioica Roxb.) as assessed by random amplified polymorphic DNA

Pointed gourd (Trichosanthes dioica Roxb.) is an economically important cucurbit and is extensively propagated through vegetative means, viz vine and root cuttings. As the accessions are poorly characterized it is important at the beginning of a breeding programme to discriminate among available genotypes to establish the level of genetic diversity. The genetic diversity of 10 pointed gourd races, referred to as accessions was evaluated. DNA profiling was generated using 10 sequence independent RAPD markers. A total of 58 scorable loci were observed out of which 18 (31.03%) loci were considered polymorphic. Genetic diversity parameters [average and effective number of alleles, Shannon's index, percent polymorphism, Nei's gene diversity, polymorphic information content (PIC)] for RAPD along with UPGMA clustering based on Jaccard's coefficient were estimated. The UPGMA dendogram constructed based on RAPD analysis in 10 pointed gourd accessions were found to be grouped in a single cluster and may represent members of one heterotic group. RAPD analysis showed promise as an effective tool in estimating genetic polymorphism in different accessions of pointed gourd.

Coagulation factor XIII deficiency. Diagnosis, prevalence and management of inherited and acquired forms

The plasma circulating zymogenic coagulation factor XIII (FXIII) is a protransglutaminase, which upon activation by thrombin and calcium cross-links preformed fibrin clots/fibrinolytic inhibitors making them mechanically stable and less susceptible to fibrinolysis. The zymogenic plasma FXIII molecule is a heterotetramer composed of two catalytic FXIII-A and two protective FXIII-B subunits. Factor XIII deficiency resulting from inherited or acquired causes can result in pathological bleeding episodes. A diverse spectrum of mutations have been reported in the F13A1 and F13B genes which cause inherited severe FXIII deficiency. The inherited severe FXIII deficiency, which is a rare coagulation disorder with a prevalence of 1 in 4 million has been the prime focus of clinical and genetic investigations owing to the severity of the bleeding phenotype associated with it. Recently however, with a growing understanding into the pleiotropic roles of FXIII, the fairly frequent milder form of FXIII deficiency caused by heterozygous mutations has become one of the subjects of investigative research. The acquired form of FXIII deficiency is usually caused by generation of autoantibodies or hyperconsumption in other disease states such as disseminated intravascular coagulation. Here, we update the knowledge about the pathophysiology of factor XIII deficiency and its therapeutic options.

Ascites, anemia and (intestinal) atresia

We report a neonate who presented antenatally with fetal ascites and fetal anemia. The cause of this remained uncertain until 2 weeks later when bowel dilatation was noted on antenatal ultrasound. Clinical signs of intestinal obstruction became evident after delivery, and ileal atresia was found at laparotomy, which was resected with primary anastomosis. Recent reports in the literature have suggested a possible connection between fetal ascites, anemia and dilated bowel with neonatal intestinal obstruction. In these cases and ours, the likely sequence of events was that of in utero midgut volvulus with bleeding into ischemic bowel, hemorrhagic ascites resulting in fetal anemia and progressive bowel dilatation occurring as a consequence of intestinal atresia. Early treatment in our patient with intrauterine blood transfusion may have altered the natural history of her condition, allowing pregnancy to progress to term with a subsequent improved outcome.

Observational assessment and correlates to blood pressure of future physicians of Bengal

INTRODUCTION

Hypertension is a modern day epidemic and growing public health problem. A sizable proportion of world populations suffer from prehypertension or hypertension.

OBJECTIVES

The present study was carried out to detect the prevalence of undiagnosed hypertension among undergraduate medical students and to identify the associated risk factors.

MATERIALS AND METHODS

The study was observational in nature and was done in medical colleges of Bengal. Study tool was a predesigned, pretested, validated, and semi-structured questionnaire containing both open-ended and close-ended questions. Data were collected through self-administration, clinical, and anthropometric examination. The data were then tabulated, analyzed and interpretation was done by using percentage and Chi-square test.

RESULTS

Most of the students (63%) were young adults, predominantly males (67%) and day scholars (71%). Almost one-third of them either suffered from hypertension or at risk of hypertension. Hypertension was found higher among male students. Family history of hypertension or diabetes mellitus was not associated with hypertension. Vegetarian or nonvegetarian diet or extra-salt consumption was also not associated with hypertension. Smoking was shown positively associated with hypertension but alcohol consumption was not. Higher per capita monthly income and overweight or obesity were shown positively associated with hypertension.

CONCLUSION

The overall prevalence of hypertension in this study was 13% and there were positive association of hypertension with multiple socio-demographic factors like age, sex, type of family, per capita monthly income, residence, BMI, smoking, etc.

Occult HBV infection among anti-HBc positive HIV-infected patients in apex referral centre, Eastern India

BACKGROUND

The prevalence of occult HBV, defined by the presence of HBV DNA in individuals with antibodies to HBV core antigen and with absence of HBV surface antigen, but its clinical significance and virological features in HIV-infected patients is still unclear.

AIM

To investigate the prevalence, clinical significance and molecular characterization of occult hepatitis B virus infection in ART-Naive HIV-positive individuals.

MATERIAL AND METHODS

Among the 1077 HIV-infected patients with different risk factors for HIV infection, 297 were HBsAg-ve ART-naive, of them 112 was randomly selected for the study. HBV DNA was tested by in-house PCR and quantified by qPCR. Molecular characterization was performed by sequencing the envelope and overlapping polymerase genes.

RESULTS

We found the prevalence of occult HBV to be 10.7% among a randomly selected group of HBsAg-ve/antiHBc+ve HIV-infected patients. Overall 33.9% (38 of 112) of the patients were antiHBc positive indicating exposure to HBV infection. HBV DNA was detected in 12/38 (31.5%) antiHBc positive samples and 50% of them had CD4 T cell count < 200 cells/mm(3). HCV coinfection was low (2.7%). No surrogate marker for OBI could be identified. Presence of antiHBs antibodies did not rule out OBI. Liver biopsy in six cases showed varying stages of chronic hepatitis. Several mutations were detected but not the common immune escape mutant G145R.

CONCLUSION

In conclusion the prevalence of OBI was significantly high among HIV coinfected patients, which highlights the importance of HBV DNA testing in these patients and indicates need for further prospective studies in larger cohorts to assess its clinical significance.

Associations between pollen counts, pollutants, and asthma-related hospital admissions in a high-density Indian metropolis

BACKGROUND

The seasonal pattern of asthma-related hospitalization has often been correlated with ambient allergen/pollutant levels.

OBJECTIVE

To examine the relationship between asthma-related hospital admissions (ARHA) and outdoor pollen, spore, and pollutant levels for adult patients in a densely populated Indian megacity Kolkata.

METHODS

ARHA data were obtained from two major teaching hospitals of the city. Pollen and spores causing allergic sensitization were identified by skin prick tests (SPTs) among respiratory allergic subjects (N = 1353). Outdoor concentrations of aeroallergens were determined using a Burkard sampler for five consecutive years (2004-2009). Levels of NO(2), SO(2), suspended particulate matters (SPMs), and respirable particulate matters (RPMs) were made available by West Bengal Pollution Control Board (WBPCB, Government of West Bengal). Poisson multivariate Poisson regression (with adjustments for overdispersion) was used to model the data. Results. We found that ARHA in Kolkata increased with predictable regularity in March and September, while remaining low in January and July. SPT showed highly positive skin reactions with grass/weed and palm pollens in respiratory allergic patients, while Aspergilli spores also evoked good sensitivity. In our regression model, the airborne pollen types, Cheno-Amaranthaceae and Cyperaceae, and the inorganic pollutant, SO(2) and RPM, were significantly associated with ARHA (p < .05).

CONCLUSION

ARHA in the megacity of Kolkata shows two seasonal peaks that can be correlated with outdoor grass/weed pollen and RPM concentrations. In contrast, the city's ambient fungal spore counts were not found to be significantly associated.

Evaluation of Cerebrospinal fluid adenosine deaminase activity as a complimentary tool in the early diagnosis of tuberculous meningitis in children

The diagnosis of tuberculous meningitis cannot be made or excluded on the basis of clinical findings. Definite laboratory diagnosis is cumbersome and time consuming. Delay in diagnosis and institution of proper treatment is directly related to poor outcome and sequalae. Adenosine deaminase activity (ADA) was estimated in cerebrospinal fluid (CSF) in addition to routine CSF analysis of 32 patients of tuberculous meningitis (TBM) and 7 patients of partially treated pyomeningitis (PTM), 10 patients aseptic meningitis (AM) and 13 patients pyogenic meningitis (PM). Mean ADA levels in CSF of TBM patients were higher (15.42 U/L) as compared to 7.21 U/L, 6.41 U/L and 7.50 U/L in PTM, AM and PM respectively. This difference of ADA values in CSF between TBM and other types of meningitis was statistically significant (p<0.01). ADA values were also compared with other biochemical and cytological parameters of CSF & a positive correlation was found with CSF protein level. Sensitivity and specificity of ADA levels in CSF of children to diagnose tuberculous meningitis was 75% and 90% respectively at 10 U/L cut off of ADA levels in CSF.

A case of leptospirosis in a child with unusual clinical manifestation

Leptospirosis is a re-emerging zoonotic disease with a worldwide distribution. In the mild form it may present as flu like illness. Severe form characterized by jaundice, renal dysfunction and hemorrhagic diathesis is referred to as Weil’s syndrome. Very few cases have been reported in India, and pediatric cases are extremely rare. We report a case of leptospirosis in a 12 year old girl who presented with irregular fever, malaise and spontaneous bleeding from nose. She also had headache, vomiting, subconjunctival hemorrhage, photophobia, pain abdomen, cervical lymphadenopathy, myalgia, and arthralgia. She developed severe coagulopathy, bilateral pleural effusion, ascitis, acalculous cholecystitis ultimately leading to ARDS and later multi-organ failure. ELISA for IgM leptospira was sent which came to be positive. She was given several units of packed cell, platelet concentrate, and plasma transfusion, and later mechanical ventilation and inotropic support. The patient was put on intravenous penicillin G.. which was continued for 10 days. Three weeks following admission, she had made a complete recovery and was discharged.
