Implication and utility of DAS-28 squeeze in rheumatoid arthritis: an Indian experience. Reumatismo 2022; 74. [PMID: 36101988 DOI: 10.4081/reumatismo.2022.1501] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2022] [Accepted: 08/10/2022] [Indexed: 11/22/2022] Open
Abstract
The purpose of this study was to compare and correlate disease activity score including 28 joints counts (DAS-28) Squeeze with DAS-28 and clinical disease activity index (CDAI) to assess disease activity (DA) in rheumatoid arthritis (RA) patients. A total of 100 RA patients were included in the study. All subjects were evaluated for disease activity using the DAS-28 Squeeze, DAS-28, and CDAI. Spearman’s rho (ρ) was calculated to determine the correlation between DAS-28 Squeeze, DAS-28, and CDAI. Cross-tabulation was performed to compare and calculate the kappa coefficient for the link between two indices. For each scale, Cronbach’s alpha was also calculated to test dependability. The average age of the study group was 43.9±11.3. The mean scores on the DAS-28 Squeeze, DAS-28, and CDAI were, respectively, 3.58±1.06, 5.06±1.56, and 22.81±14.92. p=0.001 indicated a significant correlation between DAS-28 Squeeze and DAS-28 (ρ=0.986) and CDAI (ρ=0.939) for DAS-28 Squeeze. There was a considerable correlation between all three measures at various DA levels. Cronbach’s alpha for DAS-28 Squeeze, DAS-28, and CDAI were respectively 0.716, 0.663, and 0.734. DAS-28 Squeeze exhibited a substantial positive association with DAS-28 and CDAI for assessing disease activity and appears to be a more useful and reliable method than DAS-28 and CDAI for monitoring disease activity in RA patients.

Thermal hysteresis in microtubule assembly/disassembly dynamics: The aging-induced degradation of tubulin dimers. Biochem Biophys Rep 2022; 29:101199. [PMID: 35036585 PMCID: PMC8749447 DOI: 10.1016/j.bbrep.2021.101199] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2021] [Revised: 12/29/2021] [Accepted: 12/31/2021] [Indexed: 11/08/2022] Open
Abstract
The assembly/disassembly of biological macromolecules plays an important role in their biological functionalities. Although the dynamics of tubulin polymers and their super-assembly into microtubule structures is critical for many cellular processes, details of their cyclical polymerization/depolymerization are not fully understood. Here, we use a specially designed light scattering technique to continuously examine the effects of temperature cycling on the process of microtubule assembly/disassembly. We observe a thermal hysteresis loop during tubulin assembly/disassembly, consistently with earlier reports on the coexistence of tubulin and microtubules as a phase transition. In a cyclical process, the structural hysteresis has a kinetic component that depends on the rate of temperature change but also an intrinsic thermodynamic component that depends on the protein topology, possibly related to irreversible processes. Analyzing the evolution of such thermal hysteresis loops over successive cycles, we found that the assembly/disassembly ceases after some time, which is indicative of protein aging leading to its inability to self-assemble after a finite number of temperature cycles. The emergence of assembly-incompetent tubulin could have major consequences for human pathologies related to microtubules, including aging, neurodegenerative diseases and cancer.

Abstract
Abstract
Background
Systematic reviews are usually considered as the highest level of evidence and are increasingly used in shaping cardiology policies and guidelines. However, as the rate of publishing systematic reviews increases annually, there are rising concerns regarding their quality and reporting standards.
Purpose
The current analysis provides an insight into the quality of published systematic reviews in cardiology and provides recommendations for researchers, clinicians, and stakeholders in this regard.
Methods
Using a comprehensive Medline/PubMed search, we retrieved all systematic reviews, published between 2009 and 2019 in five general cardiology journals with the highest impact factor as per the Clarivate Analytics 2019 Journal Impact Factor List (Circulation, European Heart Journal, Journal of the American College of Cardiology, Circulation Research, and JAMA Cardiology). We assessed the methodological characteristics, eligibility criteria, reporting standards, as well as review quality scores according to the AMSTAR tool.
Results
Among 352 retrieved reviews, 275 (75.3%) performed direct head-to-head analysis and 164 (46.6%) included only clinical trials. The median numbers of searched databases and included studies were 3 (IQR: 2, 3) and 13 (IQR: 7, 30). The primary outcomes were often hard clinical endpoints as mortality (39.2%) and stroke (11.9%). 64 (18.2%) registered their protocol, 208 (58.4%) used validated tools for risk of bias assessment, 177 (52.3%) assessed for publication bias, and 221 (62.8%) adhered to the PRISMA checklist. Thirty-five reviews detected significant publication bias, which was significantly associated with heterogeneity of the primary outcome. The AMSTAR quality scores were low or critically low in 71% of evaluated reviews. Further, 87 (24.7%) did not report on whether they received funding or not, 33 (9.4%) reported receiving no funding, and 232 adequately reported on their funding sources [70 (19.9%) from governmental/academic sources, 120 (34.1%) from pharmaceutical companies, and 42 (11.9%) from both sources]. analysis showed that reviews with advanced statistical analysis, those that included RCTs, adhered to the PRISMA checklist, or had higher AMSTAR quality scores had significantly higher citation metrics (p<0.05).
Conclusion
Due to the widespread low quality and poor reporting in cardiovascular systematic reviews, clinicians should be educated on the value of methodological quality in interpreting systematic review findings. In addition, academic societies and guideline writing groups should implement rigorous critical appraisal and peer review policies to improve the synthesis and utilization of systematic reviews in evidence-based cardiovascular medicine.

Association of Vitamin D Levels with Incident All-Cause Dementia in Longitudinal Observational Studies: A Systematic Review and Meta-analysis. JPAD-JOURNAL OF PREVENTION OF ALZHEIMERS DISEASE 2021; 7:14-20.

Abstract
BACKGROUND The role of vitamin D is not only limited to bone health and pathogenesis of chronic diseases. Evidence now suggests that it is also involved in the development of various dementias and Alzheimer's disease (AD). OBJECTIVE To carry out a systematic review and meta-analysis to evaluate the association between vitamin D levels and increased risk of incident all-cause dementia in longitudinal studies. DESIGN We conducted a systematic review and meta-analysis using the electronic bibliographic databases PubMed and Scopus. SETTING Prospective cohort studies. PARTICIPANTS Community-dwelling older adults. MEASUREMENTS Vitamin D serum concentrations were categorized in three groups: normal levels (>50 nmol/L), insufficient levels (25 - 49.9 nmol/L), and deficient levels (<25 nmol/L). We performed a meta-analysis using the general inverse variance method to calculate the pooled risk of AD and all-cause dementia according to vitamin D levels. Random-effects or fixed-effect model were used to calculate the pooled risk based on the heterogeneity analysis. RESULTS Five studies were included in the meta-analysis. The pooled risk of all-cause dementia and AD was significantly higher in those with deficient serum vitamin D level compared to those with normal level (1.33, CI95% [1.15, 1.54], and 1.87, CI95% [1.03, 3.41], respectively). Those with insufficient level also had a higher pooled risk of all-cause dementia and AD, but the strength of association was less robust (1.14 CI95% [1.02, 1.27] and 1.25, CI95% [1.04 - 1.51], respectively). CONCLUSION We found a gradient effect for the risk of all-cause dementia and AD according to the vitamin D level, with higher risk in those in the deficient levels group and intermediate risk in those with insufficient levels. Our findings were limited by the relatively small number of studies included in the meta-analysis and their geographic restriction.

Abstract
Abstract
Background
Patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) and having concomitant atrial fibrillation (AF) have a greater risk of adverse short- and long-term outcomes and death compared with patients in the same setting but without AF. On the other hand, the predictive value of CHA2DS2-VASc score in terms of in-hospital mortality and periprocedural adverse events following PCI among patients with ACS and AF is unknown.
Purpose
We retrospectively analyzed data of patients with the main admission diagnosis of ACS that underwent PCI and had AF during the 2004–2014 period from the large nationwide US National Inpatient Sample (NIS) database.
Methods
A CHA2DS2-VASc score was calculated for each patient and incorporated into a multivariable-adjusted logistic regression to determine its independent impact on in-hospital outcomes consisting of death, acute kidney injury (AKI), bleeding, vascular injury, and stroke/transient ischemic attack (TIA).
Results
A total of 283,890 patients with AF who underwent PCI following ACS were included in the analysis. The average reported prevalence of the AF in the whole cohort was 10.0% with a significant trend (p<0.001) of increase during the observed 10-year period. The average age of the cohort was 72.1±11 years, 63.4% were male while the median CHA2DS2-VASc score was 3 (IQR 2–4). Crude rates of adverse in-hospital outcomes were significantly higher among patient groups with higher CHA2DS2-VASc score (Table 1). Following adjustment for baseline covariates, incremental increase in CHA2DS2-VASc score was independently associated with an increased odds of in-hospital death (OR 1.20, CI 95% 1.18–1.22), periprocedural vascular injury (OR 1.18, 95% CI 1.17–1.20), bleeding (OR 1.17, 95% CI 1.16–1.18), stroke/TIA (OR 1.17, 95% CI 1.15–1.19), and AKI (OR 1.05, 95% CI 1.04–1.06) (Figure 1).
Conclusions
The CHA2DS2-VASc score provides important prognostic information in ACS patients with AF undergoing PCI and is independently associated with in-hospital death and periprocedural adverse events. Therefore, CHA2DS2-VASc score could be used as a practical and inexpensive tool for risk stratification in this population.

Endophytes enhance the production of root alkaloids ajmalicine and serpentine by modulating the terpenoid indole alkaloid pathway in Catharanthus roseus roots. J Appl Microbiol 2020; 128:1128-1142. [PMID: 31821696 DOI: 10.1111/jam.14546] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2019] [Revised: 10/15/2019] [Accepted: 11/28/2019] [Indexed: 12/15/2022]
Abstract
AIM The aim of this study was to identify and characterize promising endophytes capable of enhancing the content of root alkaloids ajmalicine and serpentine in low alkaloid yielding genotype of Catharanthus roseus cultivar Prabal and the possible mechanisms involved. METHOD AND RESULT Of the four strains isolated from alkaloid-rich genotype of C. roseus cultivar Dhawal, endophytic strains CATDLF5 (Curvularia sp.) and CATDLF6 (Choanephora infundibulifera) enhanced serpentine content by 211·7-337·6%, while CATDRF2 (Aspergillus japonicus) and CATDS5 (Pseudomonas sp.) increased the content of ajmalicine by 123·4-203·8% in cultivar Prabal. Upregulated expression of key genes, geraniol 10-hydroxylase, tryptophan decarboxylase and strictosidine synthase involved in terpenoid indole alkaloid (TIA) biosynthetic pathway was observed in endophyte inoculated plants. Upregulated Octadecanoid-derivative Responsive Catharanthus AP2/ERF domain transcription activators like ORCA3 while, and downregulation of transcriptional repressor, ZCTs (Cys2/His2-type zinc finger protein family) enhanced the expression of genes for secondary metabolite production in endophyte-inoculated plants. CONCLUSION The present work concluded that the selected endophytes of C. roseus can enhance the ajmalicine and serpentine contents by modulating the expression of structural and regulatory genes of TIA biosynthetic pathway in root. SIGNIFICANCE AND IMPACT OF THE STUDY Endophytes can play an important role to enhance in planta content of pharmaceutically important alkaloids in C. roseus and can therefore be useful in reducing the cost of production of important alkaloids.

Abstract
BACKGROUND Early diagnosis of skin cancer lesions by dermoscopy, the gold standard in dermatological imaging, calls for a diagnostic upscale. The aim of the study was to improve the accuracy of dermoscopic skin cancer diagnosis through use of novel deep learning (DL) algorithms. An additional sonification-derived diagnostic layer was added to the visual classification to increase sensitivity. METHODS Two parallel studies were conducted: a laboratory retrospective study (LABS, n = 482 biopsies) and a non-interventional prospective observational study (OBS, n = 63 biopsies). A training data set of biopsy-verified reports, normal and cancerous skin lesions (n = 3954), were used to develop a DL classifier exploring visual features (System A). The outputs of the classifier were sonified, i.e. data conversion into sound (System B). Derived sound files were analyzed by a second machine learning classifier, either as raw audio (LABS, OBS) or following conversion into spectrograms (LABS) and by image analysis and human heuristics (OBS). The OBS criteria outcomes were System A specificity and System B sensitivity as raw sounds, spectrogram areas or heuristics. FINDINGS LABS employed dermoscopies, half benign half malignant, and compared the accuracy of Systems A and B. System A algorithm resulted in a ROC AUC of 0.976 (95% CI, 0.965-0.987). Secondary machine learning analysis of raw sound, FFT and Spectrogram ROC curves resulted in AUC's of 0.931 (95% CI 0.881-0.981), 0.90 (95% CI 0.838-0.963) and 0.988 (CI 95% 0.973-1.001), respectively. OBS analysis of raw sound dermoscopies by the secondary machine learning resulted in a ROC AUC of 0.819 (95% CI, 0.7956 to 0.8406). OBS image analysis of AUC for spectrograms displayed a ROC AUC of 0.808 (CI 95% 0.6945 To 0.9208). By applying a heuristic analysis of Systems A and B a sensitivity of 86% and specificity of 91% were derived in the clinical study. INTERPRETATION Adding a second stage of processing, which includes a deep learning algorithm of sonification and heuristic inspection with machine learning, significantly improves diagnostic accuracy. A combined two-stage system is expected to assist clinical decisions and de-escalate the current trend of over-diagnosis of skin cancer lesions as pathological. FUND: Bostel Technologies.

Abstract
INTRODUCTION King's College Hospital has proudly provided a one-stop neck lump clinic since 2012. These multidisciplinary clinics allow for rapid diagnoses due to in-clinic investigations. In April 2013, ultrasound-guided core needle biopsies were introduced as an alternative/adjunct to fine-needle aspiration cytology and open biopsies for obtaining histological diagnoses. The aim of the study was to assess the impact of core needle biopsies on the diagnosis of neck lumps compared with fine-needle aspiration cytology and open biopsies between April 2015 and May 2016. MATERIALS AND METHODS Data were collected prospectively between April 2015 and May 2016 and analysed for numbers of fine-needle aspiration cytology, core needle biopsies and open biopsies performed and diagnoses made. RESULTS A total of 190 patients were seen on the clinic; 51 had fine-needle aspiration cytology and 19 procedures gave a diagnosis. Of the remainder of these patients, 21 went on to have a core needle biopsy and 12 biopsies gave a diagnosis. An additional eight patients only had a core needle biopsy, of which five biopsies gave a diagnosis. Of the ten patients who had an open biopsy, four had a previous fine-needle aspiration cytology and core needle biopsy, three only a core needle biopsy, two had neither and one had fine-needle aspiration cytology. CONCLUSION The introduction of core needle biopsies has reduced the number of open biopsies performed. With increasing acceptance of this minimally invasive technique, core needle biopsies appear to be forming the key diagnostic investigation in patients with neck lumps.

Abstract
Burden of Influenza is significantly higher in developing countries as compared to developed countries, but the data on the disease burden is less well defined in most of the developing countries including India, and consequently, constraints evolving strategies for prioritization of measures to prevent and control it. The swine flu or A(H1N1) pandemic is on the wane but the virus continues to circulate causing sporadic outbreaks even in 2013. The A(H1N1)pdm09 has replaced the previous circulating seasonal A (H1N1) virus and acquired the status of a seasonal virus. Limited influenza activity is usually seen throughout the year in India with a clear peaking during the rainy season. The rainy season in the country lasts from June to August in all the regions except Tamil Nadu where it occurs from October to December. IAP recommends the ideal time for offering influenza vaccines is just before the onset of rainy season. The efficacy/effectiveness data of trivalent inactivated influenza vaccines are also presented in different age groups and different categories of individuals. The IAP maintains its earlier recommendations of using the current trivalent inactivated influenza vaccine in all children with risk factors but not as a universal measure. IAP has now prioritized different target groups for influenza vaccination based on contribution of the group to the overall influenza burden, disease severity, and vaccine effectiveness in different age groups and categories. The current trivalent inactivated influenza vaccines incorporate the 2009 pandemic strain also, hence avert the need of a separate A (H1N1) vaccine. IAP stresses the need of more refined surveillance; large scale studies on effectiveness of seasonal influenza vaccines in Indian children, and more effective, properly matched, higher-valent influenza vaccines.

Abstract
Rhodococcus equi, a Gram positive organism, is a cause of infections in immunocompromised individuals. In humans, it mainly causes disease in those infected with human immunodeficiency virus (HIV), and generally presents as chronic pulmonary infection. It may also cause intracranial infections, which manifest as brain abscesses. This report describes a case of rhodococcus brain and pulmonary infection in a patient who did not have HIV or another disorder of cell mediated immunity. He was treated with intravenous imipenem, vancomycin, and rifampin for eight weeks and recovered from the infection.

Abstract
Although transcutaneous electrical nerve stimulation (TENS) is used extensively in inflammatory joint conditions such as arthritis, the underlying mechanisms are unclear. This study aims to demonstrate an opiate-mediated activation of descending inhibitory pathways from the rostral ventral medulla (RVM) in the antihyperalgesia produced by low- (4 Hz) or high-frequency (100 Hz) TENS. Paw withdrawal latency to radiant heat, as an index of secondary hyperalgesia, was recorded before and after knee joint inflammation (induced by intra-articular injection of 3% kaolin and carrageenan) and after TENS/no TENS coadministered with naloxone (20 microg/1 microl), naltrindole (5 microg/1 microl), or vehicle (1 microl) microinjected into the RVM. The selectivity of naloxone and naltrindole doses was tested against the mu-opioid receptor agonist [D-Ala2,N-Me-Phe4,Gly-ol5]-enkephalin (DAMGO) (20 ng, 1 microl) and the delta2-opioid receptor agonist deltorphin (5 microg, 1 microl) in the RVM. Naloxone microinjection into the RVM blocks the antihyperalgesia produced by low frequency (p < 0.001), but not that produced by high-frequency TENS (p > 0.05). In contrast, naltrindole injection into the RVM blocks the antihyperalgesia produced by high-frequency (p < 0.05), but not low-frequency (p > 0.05) TENS. The analgesia produced by DAMGO and deltorphin is selectively blocked by naloxone (p < 0.05) and naltrindole (p < 0.05), respectively. Thus, the dose of naloxone and naltrindole used in the current study blocks mu- and delta-opioid receptors, respectively. Hence, low-frequency and high-frequency TENS produces antihyperalgesia by activation of mu- and delta-opioid receptors, respectively, in the RVM.

Abstract
This study characterizes an animal model of persistent mechanical hyperalgesia induced by repeated intramuscular injections of low pH saline. Saline at pH 4, 5, 6, or 7.2 was injected twice, 2 to 10 days apart, into the gastrocnemius muscle of rats. To quantify hyperalgesia, paw withdrawal latency to radiant heat (heat hyperalgesia) and withdrawal threshold to mechanical stimuli (mechanical hyperalgesia) were measured. Two unilateral injections of low pH saline, 5 days apart, caused a pH-dependent bilateral mechanical, but not heat, hyperalgesia that lasted 30 days. Injections given 2 and 5 days apart produced a significantly greater mechanical hyperalgesia than injections given 10 days apart. Lidocaine injection into the gastrocnemius muscle or unilateral dorsal rhizotomy, 24 h after the second injection (pH 4), had no effect on the contralateral mechanical hyperalgesia. Minimal histopathology was observed in the injected muscle, and changes were similar between groups injected with pH 4 and pH 7.2. Thus, this new model of widespread, chronic muscle-induced pain is unrelated to tissue damage and is not maintained by continued primary afferent input from the site of injury.

Abstract
The prevalence of left ventricular (LV) thrombus after acute myocardial infarction (AMI) has been reported high at 20-60%. Current reperfusion therapies such as thrombolysis have shown a trend toward reducing the incidence of LV thrombosis. However, the prevalence of LV thrombus after primary percutaneous coronary intervention (PCI) for AMI has not been systematically studied. At Massachusetts General Hospital 71 consecutive patients who underwent primary PCI for acute ST elevation MI were reviewed for the prevalence of LV thrombus evaluated by echocardiography. Echocardiography was performed within 5 days of infarction. PCI was successful in all patients. The time delay from symptom onset to intervention was 191 minutes. Thrombolysis in Myocardial Infarction (TIMI) grade 3 flow was achieved in more than 80% of cases. Only 3 patients (4%) had echocardiographic evidence of LV thrombus. All 3 patients had anterior infarctions. The incidence among patients with anterior MI was 10% (3 of 30 patients). The prevalence of LV thrombus in patients treated with primary PCI for AMI is low (4%).

Abstract
A case of fourteen year old healthy girl with complaint of a discharging sinus on the lower right side of face is reported. All teeth were vital and there was no evidence of periodontitis. There was no history of extraction of a tooth. Total leucocyte count, differential leucocyte count, fasting blood sugar, chest x-ray and routine urine examination were within normal limits. Actinomycosis and scrofuloderma which simulate such a condition were ruled out by culture study. The intraoral periapical x-ray of mandibular molar showed questionable periapical changes at the time of presentation. But definite osteolysis was observed in the repeat radiograph after three months. It was decided to extract the second molar and curette the sinus tract. The extraction proved to be difficult. On examination of the extracted tooth, it was found that the mandibular second molar and second premolar were fused together. The radiograph of the tooth taken after extraction showed confluence of the premolar pulp with the periodontal membrane. On follow up, the lesion was found to heal satisfactorily.

Abstract
OBJECTIVE To compare angiographic and clinical outcomes of patients with acute myocardial infarction (AMI) who underwent primary percutaneous coronary intervention (PCI) versus rescue PCI following failed thrombolysis. BACKGROUND Patients presenting with AMI are treated either with primary PCI or with thrombolysis. When thrombolysis fails, rescue PCI is performed. METHODS AND RESULTS We compared the outcome of 105 consecutive patients with AMI who underwent either primary PCI (60 patients) or rescue PCI (45 patients) between January 1997 and January 1999. The patients were followed for up to 6 months. Time delay to reperfusion was significantly longer in the rescue PCI group (354 vs. 189 min; p < 0.001). The majority of patients received a stent (93%). Glycoprotein (GP) IIb/IIIa inhibitors were used in 53% of patients in the primary PCI group and in 22% in the rescue group. TIMI grade 3 flow was achieved in 93.3% of patients in the primary PCI group and in 88.8% in the rescue group (p = 0.08). Post-procedure ejection fraction was 53% in the primary PCI group and 47% in the rescue group (p = 0.014). A composite endpoint of death, recurrent MI, repeat PCI, coronary artery bypass grafting (CABG) and recurrent angina at 6 months occurred in 35% of the patients in the primary PCI group and 26.7% in the rescue group (p = 0.36). CONCLUSION Despite a significant delay to reperfusion and a lower immediate post-procedure ejection fraction, the clinical outcome of patients treated with rescue PCI following failed thrombolysis appears to be similar to that of patients treated with primary PCI at 6 months.

Abstract
Three dry adult human skulls, two with bilateral and one with unilateral duplication of the optic canal were found. Their gross morphologic features were studied. Optic canals were separated by a septum of variable thickness dividing the posterior part of the canal into a large canal in the usual position and a smaller one inferior to it. The skull with unilateral duplication of the right side had a bony bar forming the carotico-clinoid canal. One of the skulls was disarticulated and its sphenoid had bilaterally duplicated optic canals divided by thin septa, both having a slit. Conventional radiography and CT scans for the optic canal were performed on two of these skulls but not on the disarticulated bone, and the imaging representations of these features were correlated with the anatomic findings on the dry skull.

Abstract
OBJECTIVES To evaluate the effect of chronic irradiation on wound healing and random flap survival (FV), and the effect of transforming growth factor beta 1 (TGF-beta 1) in this setting using an animal model. DESIGN A randomized, controlled study with four groups of rats to study the effect of irradiation 4 months before surgical intervention. The effect of TGF-beta 1 on FV and wound healing also was evaluated in the irradiated and nonirradiated groups. SUBJECTS Ninety-five rats were available for evaluation. Group 1 (n = 10) was the control; group 2 (n = 28) received TGF-beta 1; group 3 (n = 28) received radiation therapy; and group 4 (n = 29) received radiation therapy and TGF-beta 1. INTERVENTION The irradiated groups received 15 Gy to their dorsal skin. Four months later all received McFarlane skin flaps. Groups 2 and 4 received topical TGF-beta 1, 4 micrograms, to the bed of the flap; groups 1 and 3 received saline. On postoperative day 7 all rats were evaluated for tensile strength and FV, and histologic staining with hematoxylin-eosin for collagen and TGF-beta 1 was done. The slides were evaluated in a "blinded" fashion. RESULTS Irradiation decreased tensile strength and FV, but not to a notable degree. Transforming growth factor beta 1 improved tensile strength in the irradiated (P = .04, Student's t test) and nonirradiated groups (P = .05, Student's t test). Transforming growth factor beta 1 also improved FV in all groups, but significantly in the irradiation plus TGF-beta 1 group (P = .001, Student's t test). The TGF-beta 1 group had the most mature collagen present at the wound edge. No qualitative difference was seen in the immunohistochemical staining for the four groups. CONCLUSIONS Transforming growth factor beta 1 improves wound healing and random FV in radiated and nonirradiated rat skin. Further study is needed to determine the radiation dose necessary to create an "impaired wound-healing model" in rats, and the optimum dose of TGF-beta 1 in this setting.

Abstract
It is known that the calcium channel blocker (CCB), nifedipine, can inhibit phagocyte oxidative burst in Plasmodium berghei-infected mice. The extent of immunopathological changes as seen by the course of infection and membrane lipid peroxidation in nifedipine-treated mice was examined in comparison with untreated mice at different parasite loads. The glutathione antioxidant system was also studied in these animals to assess its capacity to neutralize reactive oxygen species (ROS) in infected erythrocytes. The survival period of nifedipine-treated, infected mice decreased significantly. It was observed that the accumulation of reduced glutathione was greater and the decrease in glutathione peroxidase activity was less marked in drug-treated animals, suggesting better protection of the parasites against oxidative injury. The accumulation of the lipid peroxidation product, malonyldialdehyde was significantly lower in nifedipine-treated animals at all parasitemia levels studied, indicating decreased ROS generation and parasite damage. These observations reveal the shortcomings of using CCB to reverse the chloroquine resistance in malaria as this would minimize oxidative damage of parasitized red cells and phagocyte-mediated parasite killing.

Abstract
The effect of nifedipine (a calcium channel blocker) on the course of P. berghei infection was examined. It was observed that mice receiving a daily dose of 0.015 mg/kg of nifedipine had significantly shorter prepatent, patent and survival periods as compared to untreated P. berghei-infected animals (p < 0.001). This shows that the calcium channel blockers, in addition to possessing the property of reversing drug resistance during combined therapy with chloroquine, may also alter the pathophysiology of malaria infection. The decreased resistance of the host to the invading parasite suggests that the effect of CCB on the host-parasite interaction in human malaria needs to be investigated further before CCB can be used in combination with chloroquine for the treatment of chloroquine-resistant malaria or for chemoprophylaxis.

Abstract
The macrophages and neutrophils from nifedipine-treated mice, both Plasmodium berghei-infected and uninfected, showed suppressed capacity to generate oxygen free radicals as compared with untreated controls. Nifedipine treatment did not affect resting state free calcium levels in these cells. But the rise in intracellular calcium levels of macrophages and neutrophils following P. berghei infection was significantly less (P < 0.05) in nifedipine-treated mice as compared with untreated groups at various parasitaemia levels. Probably this reflects a more potent effect of nifedipine on these cells in the depolarized state. Similarly, the rise in intracellular calcium levels of these cells following formyl-Met-Leu-Phe (fMLP) stimulation was also significantly less in nifedipine-treated groups than in untreated controls at different parasitaemia levels. A positive correlation between this fMLP-stimulated rise in calcium levels and the chemiluminescence response of macrophages and neutrophils was observed in nifedipine-treated and untreated groups at various parasitaemia levels. Thus the respiratory-burst responses of these cells during P. berghei infection depend on the calcium homeostasis in the cells. The disturbances of the calcium-regulating mechanisms by nifedipine treatment resulted in subnormal phagocytic cell responses which lead to more severe and rapidly fatal P. berghei infection in these animals.

Abstract
Out of 5031 children admitted to S.N. Hospital, Agra during one year, there were 716 cases (14.2%) of accidents. Most cases were in the age group of 4-9 years; boys were affected more commonly than girls. The maximum cases occurred due to fall (44.4%), followed by road traffic accidents (26.4%) and burns (11.5%). The consequences in terms of morbidity and mortality was also high. Kerosene oil ingestion was the most common encountered form of poisoning. Incriminating environmental factors could be identified in 51.8% cases and included poorly protected roofs (23.7%), poor state of roads (10.0%), defective vehicles (7.5%), and houses opening directly on the streets (7.3%). More than half of the accidents took place at home (58.7%), followed by those on streets (30.3%) or at farmhouses (57%). Injuries caused by sharp and blunt objects were more common in villages. Only 21.4% children had received first aid, often by the family, before reaching the hospital. The overall mortality rate was 53.1/1000, but in cases of burns the mortality was (146.3/1000). This study suggests that falls and traffic accidents have the highest incidence and mortality in childhood accidents and modification of the home environment can be an effective measure to prevent such incidents.

Abstract
A total number of 8449 school children, in the 5-15 years old, group were examined clinically for evidence of valvular lesions and confirmed by roentgenographic electrocardiographic and echocardiographic findings. Twelve children (0.14%) were suffering from rheumatic heart disease (RHD). The disease was significantly more (p < 0.05) prevalent in the higher age group of 11-15 years as compared to younger children. Boys (0.18%) were affected more than girls (0.09%). The disease was more frequent among children belonging to economically backward group (0.34%) and those living in large families (0.28%). Children living in the slums had significantly (p < 0.05) higher prevalence (0.41%) than those residing in urban areas (0.06%). Only 3 out of 12 (25%) were previously diagnosed cases and remaining were diagnosed for the first time. Past history of rheumatic activity was seen in 41.67% cases. Mitral valve involvement was most frequent, being detected in 10 (83.33%) cases. Majority of cases (58.33%) had the development of symptomatic RHD within 2 years of having suffered from RF. Our study helped to detect the hitherto undiagnosed cases of RHD and showed that its prevalence was higher in older children and those from urban slums.

Abstract
One hundred and twenty children with persistent convulsions (lasting > or = 10 min) were treated with per rectal diazepam (dosage: 0.2 to 0.7 mg/kg/dose). Another group of 100 age matched children with convulsions, along with those who did not respond to rectal therapy were given intravenous diazepam in a dosage of 0.2 to 0.3 mg/kg/dose. Rectal treatment was effective in 80.83% cases while intravenous diazepam was effective in 90% cases which is statistically just significant (p < 0.05). No significant difference was observed in the efficacy of two routes of administration in controlling convulsions of different clinical types and various etiological groups (p < 0.05), except for primary generalized type where intravenous route was more effective than the rectal one (p < 0.05). No significant side-effect was observed with rectal therapy. Among the 23 (19.17%) children in whom rectal therapy failed, 12 (10%) responded to intravenous diazepam while the remaining 11 (9.17%) cases were resistant to both routes of administration.

Abstract
The oxidative metabolism of peritoneal macrophages (PM) and neutrophils from nifedipine (calcium channel blocker)-treated, Plasmodium berghei (NK 65)-infected and normal infected Swiss Albino mice was studied. A significant fall in oxidative metabolism as evidenced by decreased chemiluminescence (CL) response (P less than 0.001) was recorded both in PM and neutrophils from nifedipine-treated mice compared to the control animals. When the oxidative metabolism of these phagocytes was studied after infection of the host, higher CL response was recorded from both PM and neutrophils isolated during the early course of infection (0-1 and 5-10% parasitaemia) when compared to uninfected mice (P less than 0.001). A similar pattern was observed in the case of nifedipine-treated and infected mice even though the CL response was much lower. The increasing parasite load not only resulted in subnormal CL response but also prolonged the time required for the phagocytes to exhibit peak oxidative activity both in normal infected and CCB-treated infected mice, but the time taken to show peak CL response was shortened following drug administration compared to controls. These observations revealed the profound in vivo effect of CCB on the functioning of phagocytic leucocytes and thereby questions the use of CCB in combination with chloroquine for reversal of drug resistance.
