Health care seeking behaviour of pulmonary tuberculosis patients in Jabalpur district, Madhya Pradesh

Background: Successful tuberculosis control requires specific behaviors from patients and health providers. Therefore, understanding behaviors is fundamental to design interventions to strengthen tuberculosis control programs, including communication interventions. The aim of this study was to assess the healthcare-seeking behavior of pulmonary tuberculosis (PTB) patients in Jabalpur district.Methods: Cross-sectional study was conducted among category I new sputum positive PTB patients identified from nine designated microscopy centres from November 2013 to October 2014. Calculated sample size of 135 with a multistage random sampling method was used. Student’s t-test and Chi-square test were used along with descriptive statistics.Results: Mean age of patients was 33.87 (14.3) years, males constituted 66.7%, 72.5% patients belonged to below class IV socioeconomic status. Cough was experienced by 91.1% subjects, followed by fever (69.6%). First action was consulting a health care provider (HCP) in 41.5% followed by self-medication (21.5%). It took two attempts for 76% of patients to reach a formal health care provider. Private health care providers were consulted as first choice among HCPs by 86.7% patients, initial diagnosis was made by them in 25.9% cases. Sixty-three percent of patients were not satisfied with care at government hospitals, 41.5% had not heard of tuberculosis before their diagnosis, 59.5% of patients got information about tuberculosis from their relatives suffering from it.Conclusions: Cough is the most common and earliest symptom responsible for seeking care in pulmonary tuberculosis. Government health facilities contribute maximum to diagnosis but private health facility is the first choice for initial consultation. Patients’ perception of suggestive symptoms needs to be changed.

Patient and health provider factors affecting diagnostic delays of pulmonary tuberculosis in Jabalpur district of Madhya Pradesh, India: a cross-sectional study

Background: Delay in diagnosis of pulmonary tuberculosis (PTB) causes patients to have more severe disease, more complications and lead to higher mortality with disease spread. The aim of the study was to estimate patient proportion having delayed diagnosis of PTB and to estimate patient’ and health providers’ delay and associated factors.Methods: This cross sectional study was conducted on sample of 135 new sputum positive PTB patients from nine designated microscopy centres of Jabalpur district. Data collected on modified world health organization questionnaire. The criterion for defining delay was formulated keeping in mind the Revised TB Control Programme algorithm for diagnosis of PTB in PTB suspects. Mann Whitney U and Kruskal Wallis tests were used (α=5%).Results: Mean age was 33.87 (14.3) years. Males constituted 66.7%. Proportion of diagnostic delay was 87.4%. Median patient and health care personnel (HCP) interval were 39 days (IQR 22-75) and 34 days (IQR 12-79) respectively. Factors significantly associated with patient delay were poor knowledge about TB, smoking, symptoms perceived non serious, first action with symptom onset, and mode of transport patient used to reach the nearest public health facility. Stigma didn’t affected patient interval. Factors significantly associated with health providers’ delay were first consultations with; a non-formal HCP, private health facility, non-allopathic practitioner; consultation with multiple HCP’s; living more than half an hour away from public health facility.Conclusions: Unacceptable high delay in diagnosis, more from patient side. More attempts at increasing awareness are needed.

An Optimal Capillary Screen Cut-off of Thyroid Stimulating Hormone for Diagnosing Congenital Hypothyroidism: Data from a Pilot Newborn Screening Program in Delhi

Objective: To determine an appropriate cut-off of capillaryThyroid stimulating hormone (TSH) for congenitalhypothyroidism.Study design: Cross-sectional.Participants: 174,000 neonates born in different hospitals ofDelhi, India, from November 2014 to October 2016.Main outcome measures: Correlation between initial andrepeat capillary TSH level and subsequent venous free thyroxine(fT4) level.Results: 102 newborns with initial/ repeat capillary TSH level of≥20 mIU/L (n=174) were confirmed to have congenitalhypothyroidism at mean (SD) age of 5 (4) days. A goodcorrelation between capillary TSH level and confirmatory venousfT4 level and postnatal age of sampling was obtained (r -0.6,-0.4). The area under the ROC curve (AUC) was 0.81 (95%CI0.75 to 0.88), indicating referral capillary TSH level of 20 mIU/L tobe a good predictor of subsequent high venous TSH level.Conclusion: A cut off of ≥20 mIU/L for capillary TSH screeningbeyond 24 hours of life is optimal in the Indian setting for decidingfurther recall and workup, keeping a balance between sensitivityand recall rate.

The efficacy of azithromycin in pityriasis rosea: A randomized, double-blind, placebo-controlled trial.

Background: Macrolides are prescribed in the treatment of pityriasis rosea despite conflicting results of the limited number of studies evaluating their role in its treatment. Aim: A randomized double-blind placebo-controlled trial was conducted to evaluate the effect of azithromycin on the clinical course of pityriasis rosea. Methods: Seventy patients of pityriasis rosea were given either azithromycin (n = 35) or placebo (n = 35) and were followed-up at 2, 4 and 6 weeks. Pruritus was assessed in both groups using the visual analogue scale (VAS) . Change in the pityriasis rosea severity score (PRSS) and in the VAS were recorded as outcome measures and were compared statistically. Results: The decrease in PRSS from baseline through 2, 4 and 6 weeks within both treatment (P < 0.001) and placebo (P < 0.001) arms was found to be statistically significant; however, this change was not significantly different in the two groups (P = 0.179). Similarly, the decrease in VAS was found to be statistically significant within both groups (P < 0.001); however, the change was comparable between the two groups (P < 0.937). Analysis by Fisher's exact test did not find a significant difference between the two groups for PRSS and VAS. Conclusion: Azithromycin is not effective in pityriasis rosea and the use of macrolides for this disease should not be encouraged in clinical practice.

Female pattern hair loss.

Female pattern hair loss (FPHL) is a common cause of hair loss in women characterized by diffuse reduction in hair density over the crown and frontal scalp with retention of the frontal hairline. Its prevalence increases with advancing age and is associated with significant psychological morbidity. The pathophysiology of FPHL is still not completely understood and seems to be multifactorial. Although androgens have been implicated, the involvement of androgen-independent mechanisms is evident from frequent lack of clinical or biochemical markers of hyperandrogenism in affected women. The role of genetic polymorphisms involving the androgen and estrogen receptors is being increasingly recognized in its causation and predicting treatment response to anti-androgens. There are different clinical patterns and classifications of FPHL, knowledge of which facilitates patient management and research. Chronic telogen effluvium remains as the most important differential diagnosis. Thorough history, clinical examination, and evaluation are essential to confirm diagnosis. Patients with clinical signs of androgen excess require assessment of biochemical parameters and imaging studies. It is prudent to screen the patients for metabolic syndrome and cardiovascular risk factors. The treatment comprises medical and/or surgical modalities. Medical treatment should be initiated early as it effectively arrests hair loss progression rather than stimulating regrowth. Minoxidil continues to be the first line therapy whereas anti-androgens form the second line of treatment. The progressive nature of FPHL mandates long-term treatment for sustained effect. Medical therapy may be supplemented with cosmetic concealment in those desirous of greater hair density. Surgery may be worthwhile in some carefully selected patients.

Evaluation of antidiabetic antihyperlipidemic and pancreatic regeneration, potential of aerial parts of Clitoria ternatea

The aim of the present study was to investigate the pancreatic regeneration potential of of diferent fractions of the ethanol extract Clitoria ternatea L., Fabaceae. The antidiabetic and antihyperlipidemic potential was evaluated in streptozotocin-induced diabetic rats and correlated with its in vivo and in vitro antioxidant activity. The extract and its fractions were initially screened for acute and sub-chronic antidiabetic activity in the dose range of 100200 mg/kg. The most potent extract and fractions were further evaluated for pancreatic β-cells regeneration activity along with antioxidant and antihyperlipidemic activity. The polyphenolic, flavonoid and flavanone contents were assessed and correlated with its antidiabetic activity. The most significant pancreatic regeneration activity, antidiabetic and antihyperlipidemic activity and was shown by ethanol extract and butanol soluble fraction at a dose level of 200 mg/kg, while rutin was found to be least potent. In conclusion, pancreatic regeneration studies of ethanol extract treated rats show nesidioblastosis. It is also suggested that the factors causing regeneration are present within the pancreas. The newly generated islets may have formed from the ductal precursor cells and reduced oxidative stress helps in restoration of β-cell function.

Spectrum of Lysosomal Storage Disorders at a Medical Genetics Center in Northern India.

Background: There is limited literature available on the phenotypic and mutation spectrum of Indian patients with Lysosomal storage disorders (LSD). Objective: To elucidate the clinical, biochemical and mutation spectrum and to study the management options in Indian patients with lysosomal storage disorders. Design: Descriptive study. Subjects and Methods: All patients with lysosomal storage disorders diagnosed in the Medical Genetics department of a tertiary care institute in North India over a three year period from January 2008 to December 2010. Results: Out of the total of 93 patients clinically suspected to have LSDs, 68 (mean age at presentation 4.5 years) were confirmed to have LSDs based on the laboratory/neuroimaging findings and documentation of deficient enzymatic activity in the peripheral blood (leucocytes or plasma) and/or skin fibroblasts. The commonest clinical features at presentation were growth retardation (failure to thrive 47.2% and short stature 17.6%), hepatosplenomegaly (41.2%) and neuroregression (33.8%). A history of consanguinity was present in 32.4% of the families. Prenatal diagnosis was done in a total of 6 affected families; two pregnancies were found to be affected (one each with Gaucher disease and Tay Sachs disease) and in both cases the parents opted for termination of pregnancy. Of the remaining four pregnancies which were found to be unaffected and therefore continued, three were confirmed to be normal on post-natal follow up. Enzyme replacement therapy (ERT) is being given for a total of 8 LSD patients and all of them are showing a gradual amelioration of their symptoms and an improvement in the quality of life. Conclusions: Lysosomal storage disorders constitute an important group of genetic metabolic disorders for many of which therapeutic options are now available.

Oxidative stress and leukocyte migration inhibition response in cutaneous adverse drug reactions.

Background: Cutaneous adverse drug reactions (CADRs) may either be immunological or non-immunological. The precise mechanisms, however, are largely obscure. Other concomitant mechanisms may amplify and/or contribute to the severity and duration of a reaction. One such mechanism could be oxidative stress, a state of imbalance between reactive oxygen species, and their subsequent detoxification by antioxidants. Aims: (a) to assess the oxidative stress status in the blood of cutaneous drug reaction patients by assaying for reduced glutathione (GSH) and malondialdehyde (MDA) levels, (b) to determine the leukocyte migration inhibition (LMI) response in these patients in response to the suspected drug (s), and (c) to look for the association between oxidative stress parameters and LMI. Methods: Ethical committee approval was obtained for this study. Fresh venous blood samples were obtained from the patients of CADRs (group A) during the acute phase of reaction and healthy control subjects (group B). MDA levels, a measure of oxidative lipid damage, and reduced GSH levels, a measure of anti-oxidant capacity, were assayed in the blood samples of both groups using spectrophotometry. LMI response was measured by challenging the patients' peripheral blood mononuclear cells with the suspected drug to confirm immunological perturbation. Results: Totally 66 participants, 33 cases in group A and equal number of controls in group B, were studied. The mean MDA levels were found to be raised (P < 0.001), but GSH levels were significantly reduced in group A when compared with group B (P = <0.001). LMI response against drug(s) was performed in 33 cases (group A), out of which 25 cases showed a positive LMI response as follows: fixed drug eruption (10/25), SJS (5/25), urticaria (3/25), exfoliative dermatitis (2/25), morbilliform rash (2/25), erythroderma (1/25), vasculitis (1/25), and dapsone syndrome (1/25). The mean MDA levels were found to be significantly higher in the LMI positive CADRs (P < 0.001) when compared with LMI-negative ones, while no significant difference was seen for GSH (P = 0.100). Furthermore, there was a significant positive correlation between MDA levels and LMI response (r = 0.831, P < 0.001). On the other hand, a negative but statistically insignificant correlation was found between GSH and LMI response (r = -0.248, P = 0.271). Conclusion: CADR patients were found to be under oxidative stress based on MDA and GSH levels in the peripheral blood. There is a significant positive correlation of LMI response (against the causative drug) with MDA levels, which strongly associates oxidative stress with the immunopathogenesis in CADRs.

Epidermal nevus syndrome associated with unusual neurological, ocular, and skeletal features.

Epidermal nevus syndrome (ENS) is a rare disease, the pathogenesis of which is largely elusive. We, hereby, report an exclusive case of a 20-year-old man with verrucous ENS presented with dark colored papules and plaques along the Blaschko's lines present over the head and neck area along with fleshy growth in both eyes since birth. Limb length discrepancy and kyphoscoliosis were remarkable. Skin biopsy was compatible with verrucous epidermal nevus while the biopsy of the ocular lesion confirmed complex choristoma. MRI brain revealed calcification in the right temporal lobe. Bilateral arachnoid cyst in the middle cranial fossa, scleral osteoma in the posterior part of the right eyeball, and deformed calvarium were evident on CECT skull and orbit. The present illustration emphasizes the importance of a punctilious work up of the case.

Nail avulsion: Indications and methods (surgical nail avulsion).

The nail is a subject of global importance for dermatologists, podiatrists and surgeons. Nail avulsion is a frequently undertaken, yet simple, intriguing procedure. It may either be surgical or chemical, using 40% urea. The former is most often undertaken using the distal approach. Nail avulsion may either be useful for diagnostic purposes like exploration of the nail bed, nail matrix and the nail folds and before contemplating a biopsy on the nail bed or for therapeutic purposes like onychocryptosis, warts, onychomycosis, chronic paronychia, nail tumors, matricectomy and retronychia. The procedure is carried out mostly under local anesthesia with or without epinephrine (1:2,00,000 dilution). Besides the above-mentioned indications, the contraindications and complications of nail avulsion are briefly outlined.

Utility of MLPA in mutation analysis and carrier detection for Duchenne muscular dystrophy.

CONTEXT: Multiplex ligation probe amplification (MLPA) is a new technique to identify deletions and duplications and can evaluate all 79 exons in dystrophin gene in patients with Duchenne muscular dystrophy (DMD). Being semi-quantitative, MLPA is also effective in detecting duplications and carrier testing of females; both of which cannot be done using multiplex PCR. It has found applications in diagnostics of many genetic disorders. AIM: To study the utility of MLPA in diagnosis and carrier detection for DMD. MATERIALS AND METHODS: Mutation analysis and carrier detection was done by multiplex PCR and MLPA and the results were compared. RESULTS AND CONCLUSIONS: We present data showing utility of MLPA in identifying mutations in cases with DMD/BMD. In the present study using MLPA, we identified mutations in additional 5.6% cases of DMD in whom multiplex PCR was not able to detect intragenic deletions. In addition, MLPA also correctly confirmed carrier status of two obligate carriers and revealed carrier status in 6 of 8 mothers of sporadic cases.

Lack of association of primary iron overload and common HFE gene mutations with liver cirrhosis in adult Indian population.

Aim To find out the association of common HFE mutations (viz., C282Y and H63D) with primary iron overload (PIL) in liver cirrhosis (CLD) patients of Indian origin. Methods Polymerase chain reaction-restriction fragment length polymorphism method was used for screening C282Yand H63D mutation in 496 CLD patients (hepatitis B virus associated cirrhosis (HBVc)=74, hepatitis C virus associated cirrhosis (HCV)=50, alcoholic cirrhosis with hepatitis (ALcW) = 38, alcoholic cirrhosis without hepatitis (ALc)=92, cryptogenic cirrhosis (CC)=242) and 502 healthy controls. Transferrin saturation of >45 or serum ferritin of >300 ng/mL (males)/>200 ng/mL (females) with normal total exogenous iron intake was suggestive of PIL. Histological liver iron grading was done by Perl’s Prussian blue stain. Results Of 496 patients, 13 (2.6; 9 CC, 2 ALc, 1 HBVc, 1 AlcW) had PIL. However, only two (15.3) of 13 patients (1 CC and 1 HBVc) were positive for H63D heterozygous mutation. All the subjects were found to be C282Y wild type, except a single case of double heterozygous (C282Y/H63D) who however, did not have PIL. Overall frequency of H63D allele in patients and controls was not significantly different (5.95 and 4.58 respectively, p=0.17). A highly significant H63D allele frequency (p<0.005) was observed in HBVc (10.82) and ALcW (11.84) groups but they were not associated with PIL. Conclusion The frequency of PIL, and the HFE gene mutaion (C282Y) are both rare in Indian patients and explain why hemochromatosis is a rare cause of liver cirrhosis in India. A highly significant H63D allele frequency in HBV and alcohol-related cirrhosis suggest a possible predisposing role for liver fibrosis of this allele.
