Family vitiligo impact scale: A scale to measure the quality-of-life of family members of patients with vitiligo

Background: Vitiligo places a significant psycho-social burden on caregivers and family members. Aims: The aim of the study was to develop and preliminarily validate a scale to measure the psychosocial impact of vitiligo on adult family members. Methods: Themes that emerged from qualitative interviews and a focus group discussion with family members were used to generate items for a preliminary scale, followed by pre-testing and scale development. The new scale was then tested with two comparator scales and a global question. Results: A preliminary scale with 32 items was pilot tested on 30 participants. Following this, the scale was condensed to 16 items in 12 domains that were administered to 159 participants. Scale scores ranged from 0 to 48 with a mean of 19.75 ± 12.41. The scale had excellent internal consistency with Cronbach’s alpha coefficient of 0.92 (0.70–0.95) and also showed good test-retest reliability at two weeks (r = 0.946). The scale showed criterion, convergent and known group validity. Limitations: It was conducted in a large teaching hospital which may have resulted in selection of patients with persistent or progressive disease and more worried family members. Vitiligo is highly stigmatized in our country and the performance of the scale may need to be evaluated in other communities and cultures as well where stigma is less oppressive. Conclusion: Family Vitiligo Impact Scale appears to be an easy-to-complete, reliable and valid instrument to measure the psychosocial impact of vitiligo in family members of patients. It may be useful as an outcome measure in both clinical and research settin

Antibiotic stewardship initiative in a Medicine unit of a tertiary care teaching hospital in India: A pilot study

Background & objectives: The models for implementation of antibiotic stewardship programme (ASP) in the acute care settings of developing countries are lacking. In most of the hospitals, patient turnover is high and a proper system for recording antibiotic-related information and tracking hospital-acquired infections is not in place. This pilot study was conducted in a tertiary care teaching hospital in north India to assess the feasibility of implementation of an ASP in a Medicine unit and to evaluate the effect of implementation as per the criteria applicable in this set up. Methods: A pre-post-quasi-experimental non-randomized study was conducted in two phases. In the first phase, current practices in the Medicine wards were observed. In the second phase, the ASP was implemented in a single Medicine unit, along with prospective audit and feedback, tracking of the process, as well as outcome measures. Patient risk stratification, blood culture on day one, day 3 bundle, dose optimization, de-escalation and intravenous to oral conversion of antibiotics were the key elements focused upon. Results: There was a significant improvement in the appropriateness of antibiotic prescription (66 vs. 86%, P<0.001) and reduction in the mean number of antibiotics used per person (4.41 vs. 3.86, P<0.05) along with decrease in the duration of hospital stay (17 vs. 14 days, P<0.05). There was a significant improvement in sending of blood cultures on day one during the stewardship phase (P<0.001). Interpretation & conclusions: The ASP approach used in our pilot study may be feasible and beneficial. However, it needs further confirmation in other settings and on a large scale.

Distribution of Chlamydia trachomatis omp A genotypes in patients attending a sexually transmitted disease outpatient clinic in New Delhi, India

Background & objectives: Limited data are available on the typing of Chlamydia trachomatis in India. Serovars D to K of C. trachomatis are chiefly responsible for urogenital infections. Thus, this study was conducted to determine the distribution of C. trachomatis serovars in patients with urogenital infections and to characterize omp A gene of the detected C. trachomatis isolates by sequence analysis. Presence of other co-infections was also evaluated. Methods: Endocervical swabs were collected from 324 women and urethral swabs/urine were collected from 193 men attending the sexually transmitted diseases outpatient clinic. The samples were screened for C. trachomatis by cryptic plasmid PCR and omp A gene PCR. Genotyping was performed by PCR-restriction fragment length polymorphism (RFLP) and sequencing of the omp A gene. Samples were screened for genital mycoplasmas, Neisseria gonorrhoeae, Treponema pallidum and human immunodeficiency virus (HIV). Results: C. trachomatis was found in 15.0 per cent men and 10.8 per cent women. Serovar D was the most prevalent followed by serovars E, F, I and G. Twenty two C. trachomatis isolates were selected for omp A gene sequencing. No mixed infection was found. Variability in omp A sequences was seen in 31.8 per cent cases. Both PCR-RFLP and omp A gene sequencing showed concordant results. The presence of Ureaplasma spp. and Mycoplasma hominis was observed in 18.7 and 9.5 per cent patients, respectively. Co-infection of C. trachomatis was significantly associated with Ureaplasma urealyticum and HIV. Interpretation & conclusions: The high occurence of C. trachomatis infections warrants its screening in addition to other sexually transmitted infections namely U. urealyticum and HIV. Genotyping of the omp A gene may provide additional information for vaccine development.

Comparison of grading of aortic stenosis between transthoracic and transesophageal echocardiography in adult patients undergoing elective aortic valve replacement surgeries: A prospective observational study

Introduction: Intraoperative trans-esophageal echocardiography (TEE) has been found to underestimate severity of aortic stenosis (AS) compared to trans-thoracic echo (TTE). We conducted a prospective study comparing pre induction TTE and intra operative TEE grading of AS in patients posted for aortic valve replacement surgeries. Methods: Sixty patients with isolated AS who were undergoing aortic valve replacement were enrolled in our study. Baseline TTE was done and after induction of anesthesia, TEE was done. Mean gradient across aortic valve, peak jet velocity, aortic valve area (AVA) by continuity equation and dimensionless index (DI) were assessed in both. Results: Mean gradient decreased from 56.4 in TTE to 39.8 mm Hg in TEE leading to underestimation of AS in 74.5% of patients (P < 0.0). Mean of peak jet velocity also decreased from 500 in TTE to 386cm/s in TEE (P < 0.01). In 76 % of patients this led to reduction of AS grade from severe to moderate. Mean AVA was 0.67 cm2 in TTE and 0.69 cm2 in TEE. Though there was 0.02 cm2 increase, it was not statistically significant (P = 0.07). All the patients remained as severe AS in TEE. DI mean was 0.19 in both TTE and TEE (P = 0.14).It led to underestimation of severity in 6% of patients in TEE. Conclusion: Our study shows that AVA measurement by continuity equation and DI are reliable in grading aortic stenosis while performing intraoperative TEE. Mean gradient and jet velocity can be significantly reduced.

Mutations in FGFR3 gene associated with maxillary retrognathism

Context: Understanding the role of fibroblast growth factor receptor (FGFR) in the regulation of bone development and disease will ultimately lead to better prevention and treatment of related bone deformities and disorders. Aims: To evaluate the role of gene FGFR3 in individuals with retrognathic maxilla by polymerase chain reaction (PCR) technique at molecular level and evaluate the significance of the same. Settings and Design: Hospital based fundamental research involving individuals having maxillary retrognathism. Methodology: A total of 62 individuals (30M and32F) who were willing to take part in the study were selected from cephalometric measurements of N I A and the length PNS to ANS. The institution based basic genetic research study involved collection of fresh blood samples, DNA extraction, PCR analysis, and amplification using the specifically designed forward and reverse primers for targeting the commonly occurring mutations in FGFR3 gene. Further the products were sequenced to evaluate the presence of any novel mutations. Results: The targeted single-nucleotide polymorphisms, at position 1138 in exon 10 of the FGFR3 gene were not identified in the analyzed blood samples. The detailed sequencing of full gene revealed the presence of 2 novel mutations, Exon 3: A213G and Exon 3: A223A/G in one individual. Conclusions: The present study indicated 2 novel mutations in gene FGFR3 in individual with maxillary retrognathism. The genetic–environmental interactions might have played a significant role in the expression of retrognathic maxilla.

Sonication of antibiotic loaded cement spacers: A valuable technique for detection of infection persistence in two-stage revision for infected joint arthroplasty

We evaluated the diagnostic utility of sonication of antibiotic loaded cement spacers comparing with periprosthetic tissue cultures for the detection of persisting infection in 14 patients undergoing staged procedures. Sonication improved microbial detection of intraoperative cultures from 14.2% to 28.5% (P = 0.481). Routine sonication of spacers is recommended.

Objective: To compare the adequacy and efficacy of differentdoses of vitamin D3 in pre-pubertal girls.Design: Cluster Randomized controlled trial.Setting: Public school in Delhi, India, between August 2015 andFebruary 2016.Participants: 216 healthy pre-pubertal girls, aged 6.1-11.8 years.Intervention: Daily supplementation with 600 IU (n=74), 1000 IU(n=67) or 2000 IU (n=75) of vitamin D3 under supervision for 6months.Outcome measures: Primary: Rise in serum 25 hydroxy VitaminD (25(OH)D); Secondary: Change in bone formation andresorption markers.Results: Following 6 months of supplementation, the mean (SD)rise in serum 25(OH)D was maximum with 2000 IU (24.09 (8.28)ng/mL), followed by with 1000 IU (17.96 (6.55) ng/mL) and 600 IU(15.48 (7.00) ng/mL). Serum 25(OH)D levels of ?20 ng/mL wereseen in 91% in 600 IU group , 97% in 1000 IU group and 100% in2000 IU group. The overall mean (SD) rise in urinary calciumcreatinine ratio (0.05 (0.28) to 0.13 (0.12) mg/mg), and serumprocollagen type I N-terminal propeptide (538.9 (199.78) to 655.5(218.24) ng/mL), and reduction in serum carboxy-terminaltelopeptide (0.745 (0.23) to 0.382 (0.23) ng/mL) was significant(P<0.01). The change in the above parameters was comparableamong the three groups after adjustment for age.Conclusion: Daily vitamin D supplementation with 600 IU to 2000IU for 6 months results in Vitamin D sufficiency in >90% of pre-pubertal girls

Coagulase‑negative staphylococci causing blood stream infection at an Indian tertiary care hospital: Prevalence, antimicrobial resistance and molecular characterisation.

Introduction: Recent years have seen a rise of coagulase‑negative staphylococci (CoNS) from common contaminants to agents of nosocomial blood stream infections (BSI’s). Molecular typing and establishing a correlation with antibiotic resistance is essential particularly in countries like India where genotyping studies for drug‑resistant CoNS are sparse. Methods: A prospective study was done over 18 months, wherein 42,693 blood samples were received, and 59 patients with BSI due to CoNS were evaluated. The isolates recovered were identified by a biochemical test panel and matrix‑assisted laser desorption ionization – time of flight mass spectrometry followed by antimicrobial susceptibility testing by Kirby–Baur disc diffusion method and E‑test strips. Staphylococcal chromosomal cassette mec (SCCmec) element was characterised by multiplex polymerase chain reaction for all methicillin‑resistant (MR) isolates. Results: The majority of CoNS isolated were constituted by Staphylococcus haemolyticus (47.5%) followed by Staphylococcus epidermidis (33.9%), Staphylococcus hominis (11.86%), Staphylococcus cohnii (5.08%) and Staphylococcus warneri (1.69%). Among all isolates 57.6% were MR with statistically significant higher resistance versus methicillin sensitive‑CoNS. This difference was significant for erythromycin (76% vs. 44%, P = 0.011), rifampicin (50% vs. 12%, P = 0.002) and amikacin (26.5% vs. 4%, P = 0.023), ciprofloxacin (64.7% vs. 20%, P = 0.001) and cotrimoxazole (55.9% vs. 20%, P = 0.006). SCCmec type I was predominant (61.8%, P = 0.028) and exhibited multidrug resistance (76.2%). Coexistence of SCCmec type I and III was seen in 8.82% MR isolates. Conclusion: CoNS exhibit high antimicrobial resistance thereby limiting treatment options. The presence of new variants of SCCmec type in hospital‑acquired CoNS may predict the antibiotic resistance pattern. This is the first evaluation of the molecular epidemiology of CoNS causing BSI from India and can serve as a guide in the formulation of hospital infection control and treatment guidelines.

Prevalence of metabolic syndrome and cardiovascular changes in patients with chronic plaque psoriasis and their correlation with disease severity: A hospital-based cross-sectional study.

Background: Previous epidemiological studies suggest an association between psoriasis and metabolic syndrome and risk of subclinical atherosclerosis. However, there is a paucity of data in the Indian population on these associations. Objectives: To evaluate the prevalence of metabolic syndrome and subclinical atherosclerosis in patients with chronic plaque psoriasis compared to healthy controls and to correlate the prevalence of metabolic syndrome with severity of psoriasis. Methods: A hospital-based cross-sectional study was performed on 140 patients with chronic plaque psoriasis and 140 controls. Psoriasis was categorized as mild, moderate and severe based on psoriasis area and severity index (<10, 10–14 and ≥15, respectively) and as disease of short (<1 year), intermediate (1–3 years) and long duration (>3 years). In all patients and controls, body mass index was calculated, blood pressure and waist circumference were measured and fasting blood sugar and lipid profi le were estimated. Metabolic syndrome was diagnosed by the presence of 3 or more of the modifi ed National Cholesterol Education Program’s Adult Treatment Panel III criteria. A subset of 30 psoriatic patients and 30 healthy controls were selected by the systematic sampling method for cardiac evaluation including electrocardiography, echocardiography and carotid intima-media thickness measurement. Results: The prevalence of metabolic syndrome was signifi cantly more in psoriatic patients than in controls (39.3% vs. 17.1%, odds ratio = 3.13). Psoriatic patients also had a signifi cantly higher prevalence of hypertension, abdominal obesity and diabetes. There was a signifi cant trend to increase in prevalence of metabolic syndrome, hypertension and type 2 diabetes with increased severity and longer duration of the psoriasis. Patients with psoriasis had signifi cantly higher carotid intima-media thickness (mean 0.61 mm ± 0.01 mm vs. 0.37 mm ± 0.01 mm) than controls. Limitation: This was a hospital-based cross-sectional study with a relatively small sample size. A prospective study with a larger sample would have validated the results further. Conclusion: There is a signifi cantly higher prevalence of metabolic syndrome in psoriasis patients as compared to controls; the prevalence of metabolic syndrome and its components increases with severity and duration of psoriasis. There is a higher prevalence of subclinical atherosclerosis in patients with psoriasis thus increasing the risk of cardiovascular disease. We suggest that patients with moderate to severe psoriasis be screened routinely for metabolic syndrome and cardiovascular disease and encouraged to correct modifi able cardiovascular risk factors.

Age of Onset of Puberty in Apparently Healthy School Girls from Northern India.

Objective: To determine the age of pubertal onset and menarche in school-going girls, and to assess the impact of obesity on pubertal timing. Design: Cross-sectional Setting: Seven schools across Delhi, India. Participants: 2010 school girls, aged 6-17 years Methods: Anthropometric measurement and pubertal staging was performed for all subjects. Menarche was recorded by ‘status quo’ method. Body mass index was used to define overweight/obesity. Serum gonadotropins and serum estradiol were measured in every sixth participant. Main outcome measure: Age at thelarche and menarche—analyzed for entire cohort and stratified based on body mass index. Results: Median (95% CI) ages of thelarche, pubarche and menarche were 10.8 (10.7-10.9) y, 11.0. y (10.8-11.2) y and 12.4 y (12.2-12.5) y. Overweight/obese girls showed six months earlier onset of thelarche and menarche than those with normal BMI (P<0.05). Serum gonadotropins did not vary significantly in overweight/obese subjects. Conclusion: The study provides the normative data for pubertal growth in Indian girls. Pubertal onset occurs earlier in overweight and obese girls.

Declining trends of Syphilis seroprevalance among antenatal clinic cases and STD clinic cases in a tertiary care centre: From January 2002 to December 2012.

Syphilis affects nearly 1.36 million pregnant women, majority of these cases being concentrated in the developing countries. We aimed at analysing the 11 years’ trends in syphilis seroprevalence in antenatal clinics (ANC) and STD clinic cases. Laboratory data of syphilis cases from 2002-2012 were retrospectively analysed. Out of the total 73642 cases, 393 (0.53%) tested positive for Syphilis. A statistically signifi cant decline in syphilis prevalence was found in both ANC and STD clinic cases. The efforts of various interventional programs should continue to make the screening and treatment facilities readily accessible to continue the decline in syphilis seropositivity.

Prevalence of tuberculosis in Faridabad district, Haryana State, India.

Background & objectives: Epidemiological information on tuberculosis (TB) has always been vital for planning control strategies. It has now gained further importance for monitoring the impact of interventions to control the disease. The present study was done to estimate the prevalence of bacillary tuberculosis in the district of Faridabad in Haryana State of India among persons aged older than 15 years. Methods: In this cross-sectional study, residents of Faridabad district were assessed for the prevalence of tuberculosis. Twelve rural and 24 urban clusters with estimated populations of 41,106 and 64,827 individuals were selected for the study. Two sputum samples were collected from individuals found eligible for inclusion. The samples were also cultured by modified Petroff’s method and were examined for growth of Mycobacterium tuberculosis once a week for eight weeks. A person found positive by smear and/or culture was identified as sputum-positive pulmonary TB positive. Results: A total of 105,202 subjects were enumerated in various clusters of the Faridabad district. There were 50,057 (47.58%) females and 55,145 (52.42%) males. Of these 98,599 (93.7%) were examined by the study group (47,976 females; 50,623 males). The overall prevalence of sputum smear or culture positive pulmonary tuberculosis in our study was found to be 101.4 per 100,000 population. Interpretation & conclusions: The present results showed that the prevalence of sputum positive pulmonary tuberculosis was higher in Faridabad district than the notification rates recorded by the World Health Organization for the contemporary period, a disparity that could be explained by a difference in case detection strategy employed for the study.

Institutional experience of mucormycosis over a period of 10 years - retrospective case series.

Mucormycosis is an invasive fungal infection seen in immunocompromised patients. Most common presentation is face or orbital pain, headache, lethargy, visual loss, proptosis, or palatal ulcer. Because of its angioinvasive properties, it can rapidly spread to intracranial tissues and orbit. It can lead to fatal complications such as blindness, intracranial infections, convulsions and even death. Aim of current study was to diagnose this condition; a high index of suspicion is required. Blackish crusts are characteristically seen and Potassium hydroxide (KOH) staining of these crusts can give a rapid diagnosis. Methods: Study Design was retrospective review of the charts. We reviewed the charts between January 2001 and December 2010 and compiled together 60 cases of mucormycosis. Results: The most common presentation was orbital cellulitis. Some patients presented with features of acute sinusitis. The most common cause of immunosuppression was diabetes mellitus. Patients were started on amphotericin. The prognosis was bad in 7 patients who lost vision and 8 patients died. Conclusion: Diagnosis in the early stage needs a high degree of suspicion. The underlying illness, the time between the onset of the disease and the establishment of treatment, and the occurrence of cerebral ischemic events play a role in worse survival rates.

Central venous catheter related bloodstream infections in medical intensive care unit patients in a tertiary referral centre.

Aims. To determine the incidence of central line associated bloodstream infections (CLABSIs) in the medical intensive care unit (ICU) and ward setting at All India Institute of Medical Sciences (AIIMS), New Delhi. Settings and Design. The study was conducted in the medical ICU, a 9-bedded ICU at the AIIMS, a tertiary care teaching hospital. The study design was a prospective observational study. Methods. One hundred patients admitted to medical ICU and the ward at AIIMS with an indwelling, non-tunnelled central venous catheter (CVC) in place at admission and those with a hospital stay with indwelling CVC for more than 48 hours were monitored. These patients were followed daily for the development of new onset sepsis 48 hours after insertion of CVC, in which case three sets of blood samples for culture were drawn over a span of 24 hours. Statistical Methods. Incidence of CLABSIs was measured per 1000 central line days. Results. One hundred patients hospitalised for an aggregate 1119 days acquired 29 hospital-acquired infections (HAIs), a rate of 38.8% or 31.2 HAIs per 1000 hospital days. The incidence of bloodstream infections (BSIs) in this group was 6.8%. No case of laboratory confirmed CLABSIs could be demonstrated. Incidence of clinical sepsis was 27.6% or 8.2 per 1000 CVC days. There were 9 cases out of the 29 patients (39.7%) who had evidence of HAIs with no apparent focus of infection. Only one of these cases had evidence of BSI with isolation of Staphylococcus aureus in both CVC tip culture and the simultaneous blood culture; however the antibiograms were different. Conclusions. The low rate of BSIs in the present study and the absence of occurrence of a laboratory confirmed CLABSI should be interpreted in the light of the small sample size of the study and the multitude of antibiotics received before the development of HAI.

Prospective study estimating healthcare associated infections in a paediatric hemato-oncology unit of a tertiary care hospital in north India.

Background & objectives: Healthcare associated infections (HAIs) are responsible for morbidity and mortality among immunocompromised and critically ill patients. We undertook this study to estimate the burden of HAIs in the paediatric cancer patients in a tertiary care hospital in north India. Methods: This prospective, observational study, based on active surveillance for a period of 11 months was undertaken in a 4-bedded isolated, cubicle for paediatric cancer patients. Patients who stayed in the cubicle for ≥48 h, were followed prospectively for the development of HAIs. Results: Of the 138 patients, 13 developed 14 episodes of HAIs during the study period. Patient-days calculated were 1273 days. Crude infection rate (CIR) and incidence density (ID) of all HAIs were 9.4/100 patients and 11/1000 patient-days, respectively. Of the 14 episodes of HAIs, seven (50%) were of blood stream infections (HA-BSI), five (36%) of pneumonia (HAP) and two (14%) urinary tract infections (HA-UTI). The CIRs of HA-BSI, HAP and HA-UTI were 5.1, 3.6 and 1.4/100 patients, respectively. The corresponding IDs were 5.5, 3.9 and 1.6/1000 patient-days, respectively. Mean length of stay was significantly higher in patients who developed an HAI [13.8 (range 7-30), median (Interquartile range) 12 (11-14)] vs 7.5 days [range 2-28, median (interquartile range) 7 (5-9); P<0.0001]. Also mortality was significantly higher in patients who developed an HAI [23% (3/13) vs 3% (4/125), P<0.05]. Interpretation & conclusions: The incidence of HAIs in the paediatric cancer patients in the study was 11/1000 patient days, of which HA-BSIs were the commonest. HAIs were associated with an increase in morbidity and mortality amongst this high risk patient population.

Comparison of Analgesic Effect of Direct Breastfeeding, Oral 25% Dextrose Solution and Placebo during 1st DPT Vaccination in Healthy Term Infants: A Randomized, Placebo Controlled Trial.

Objective: To compare analgesic effect of direct breast feeding, 25% dextrose solution and placebo as we give 1st intramuscular whole cell DPT injection to 6week - 3month old infants. Design: Randomized, placebo controlled trial. Setting: Immunization clinic of Department of Pediatrics, LLRM Medical College. Participants: Infants coming for their 1st DPT vaccination were randomized in to three groups of 40 each. Outcome measures: The primary outcome variable was the duration of cry after vaccination. Secondary outcome variables were Modified Facial Coding Score (MFCS) and latency of onset of cry. Results: 120 babies were equally enrolled in breast feed group, 25% dextrose fed group and distilled water fed group. Median (interquartile range) of duration of cry was significantly lower in breast fed (33.5 (17-54) seconds) and 25% dextrose fed babies (47.5 (31-67.5) seconds) as compared to babies given distilled water (80.5 (33.5-119.5) seconds) (P<0.001). MFCS at 1 min and 3 min was significantly lower in direct breast fed and dextrose fed babies. Conclusions: Direct breastfeeding and 25% dextrose act as analgesic in young infants undergoing DPT vaccination in young infants less than 3 month of age.

Association of Chlamydia trachomatis infection with human papillomavirus (HPV) & cervical intraepithelial neoplasia - A pilot study.

Background & objectives: Human papillomavirus (HPV) is the necessary cause of cervical cancer and Chlamydia trachomatis (CT) is considered a potential cofactor in the development of cervical intraepithelial neoplasia (CIN). The objective of this pilot study was to determine the association of CT infection with HPV, other risk factors for cervical cancer, and CIN in symptomatic women. Methods: A total of 600 consecutively selected women aged 30-74 yr with persistent vaginal discharge, intermenstrual/postcoital bleeding or unhealthy cervix underwent conventional Pap smear, Hybrid Capture 2® (HC2) testing for HPV and CT DNA and colposcopy, with directed biopsy of all lesions. Results: HPV DNA was positive in 108 (18.0%) women, CT DNA in 29 (4.8%) women. HPV/CT co-infection was observed in only four (0.7%) women. Of the 127 (21.2%) women with Pap >ASCUS, 60 (47.2%) were HPV positive and four (3.1%) were CT positive. Of the 41 women with CIN1 lesions, 11 (26.8%) were HPV positive, while two were CT positive. Of the 46 women with CIN2+ on histopathology, 41 (89.1%) were HPV positive, two (4.3%) were CT positive and one was positive for both. The risk of CIN2+ disease was significantly increased (P<0.05) by the following factors: age <18 yr at first coitus, HPV infection and a positive Pap smear. Older age (>35 yr), higher parity, use of oral contraceptives or smoking did not show any significant association with HPV or abnormal histopathology. Parity >5 was the only risk factor positivity associated with CT infection (P<0.05). Interpretation & conclusions: Our findings showed that CT infection was not significantly associated with CIN, and most of its risk factors, including HPV infection, in symptomatic women. Longitudinal studies with carefully selected study sample would be able to answer these questions.

Vitiligo impact scale: An instrument to assess the psychosocial burden of vitiligo.

Background : Vitiligo is a disease that significantly impairs quality of life. Previous studies have shown that vitiligo has an impact that may not correlate with the size and extent of depigmentation, indicating a need for an independent measure of the psychosocial burden. Aims : To develop a rating scale to assess the psychosocial impact of vitiligo. Methods : The study was undertaken in three broad phases: item generation, pre- and pilot testing, and test administration. Items were generated largely from a qualitative study using semi-structured interviews of patients. Face and content validity were assessed through pre- and pilot testing in 80 patients and the final version was administered to 100 patients who also received the Dermatology Life Quality Index (DLQI) and the Skindex-16. Each patient also underwent a physician global assessment (PGA) of the impact of vitiligo. Test-retest reliability was assessed in 20 patients. Results: Of 72 items initially generated for the scale, 27 were retained in the final version. Subjects were able to comprehend the items and took about 5-7 min to complete the instrument. The scale was internally consistent (Cronbach's α = 0.85). Scores on the scale correlated moderately well with the DLQI and the Skindex (Spearman rank correlation: 0.51 and 0.65, respectively). The scale was able to discriminate between patients having mild and those having moderate and severe impact as assessed by PGA. The test-retest reliability coefficient (Spearman rank correlation) was 0.80. Conclusion: The Vitiligo Impact Scale appears to be a valid measure of the psychosocial impact of vitiligo and this instrument may be useful both in the clinic and in clinical trials.

Prevalence and aetiology of anaemia in lymphoid malignancies.

Background. We prospectively studied the prevalence, type and causes of anaemia in newly diagnosed patients with lymphoid malignancies. Methods. Between January 2007 and June 2008, a total of 316 newly diagnosed, consecutive patients (aged 15 years or above) of Hodgkin lymphoma, non-Hodgkin lymphoma and chronic lymphocytic leukaemia with anaemia (haemoglobin <11 g/dl), were analysed to determine the prevalence and a subgroup of 46 patients was analysed for the cause of anaemia. Results. Hodgkin lymphoma, non-Hodgkin lymphoma and chronic lymphocytic leukaemia were the diagnoses in 81 (25.8%), 203 (64.7%) and 30 (9.6%) patients, respectively. Anaemia was present in 134 patients (42.4%). Anaemia of chronic disease was present in 33/46 (71.7%) and iron deficiency in 18/46 (39.1%) patients. Vitamin B12 and/or folate deficiency was detected in 10/46 (21.7%) patients (B12 deficiency alone in 7, folate deficiency alone in 1 and combined B12 and folate deficiency in 2). Autoimmune haemolytic anaemia was detected in 5/46 (10.9%) although direct Coombs test was positive in 17/46 (37%) patients. Among patients with Hodgkin lymphoma and non-Hodgkin lymphoma, anaemia due to bone marrow involvement was present in 16/40 (40%). In most patients with bone marrow involvement, anaemia was due to other causes. In only 3 patients, anaemia was attributable to bone marrow involvement alone. Anaemia was multifactorial in 18/46 (39.1%) patients. Nutritional deficiency alone or in combination was present in 22/46 (47.8%) patients. Conclusion. Anaemia is common in lymphoid malignancies at initial presentation. Besides managing anaemia of chronic disease and bone marrow involvement, nutritional and autoimmune causes should be ruled out.
