Non invasive and surgical measurement of length of soft tissue from the tip of interdental papilla to the alveolar crest

AbstractBackgroundVarious methods, including clinical and radiographic techniques, can be used to assess periodontal regeneration in interproximal areas. The goal of the present study was to compare the papilla length relative to the alveolar bone crest measured by clinical, intrasurgical, and radiographic techniques.Materials and methodsThe study sample included 250 interproximal papillae in 68 patients with generalized chronic periodontitis. The papilla length from the alveolar bone crest was measured clinically (as the actual papilla length, APL), intrasurgically (as the bone probing length, BPL), and radiographically (as the radiographic bone length, RBL). Measurements were standardized by using acrylic resin stents, XCP rinn, a paralleling technique, and/or a radiographic grid.ResultsThe mean (± standard deviation) for RBL was 4.9±0.8mm, BPL was 5.1±0.6mm, and APL was 5.1±0.6mm. Correlations between RBL and APL and between BPL and APL were 0.918 and 0.943, respectively (both P<0.01).ConclusionsIf the clinical recordings are appropriately standardized, then noninvasive radiographic methods can be used to evaluate the papilla length with good accuracy

Prolylcarboxypeptidase (PRCP) as a new target for obesity treatment

Recently, we serendipitously discovered that mice with the deficiency of the enzyme prolylcarboxypeptidase (PRCP) have elevated α-melanocyte-stimulating hormone (α-MSH) levels which lead to decreased food intake and weight loss. This suggests that PRCP is an endogenous inactivator of α-MSH and an appetite stimulant. Since a modest weight loss can have the most profound influence on reducing cardiovascular risk factors, the inhibitors of PRCP would be emerging as a possible alternative for pharmacotherapy in high-risk patients with obesity and obesity-related disorders. The discovery of a new biological activity of PRCP in the PRCP-deficient mice and studies of α-MSH function indicate the importance and complexity of the hypothalamic pro-opiomelanocortin (POMC) system in altering food intake. Identifying a role for PRCP in regulating α-MSH in the brain may be a critical step in enhancing our understanding of how the brain controls food intake and body weight. In light of recent findings, the potential role of PRCP in regulating fuel homeostasis is critically evaluated. Further studies of the role of PRCP in obesity are much needed

Effectiveness of crossword puzzle as an adjunct tool for active learning and critical thinking in Pharmacology

Background: Modern pedagogic methodologies are being introduced in Medical education and there is a growing evidence of crossword puzzle as an educational tool for active learning, problem solving and critical thinking. The aim of the study was to study the effectiveness of crossword puzzle as an adjunct to the conventional lecture for active learning and critical thinking in Pharmacology. This was a parallel group; pre and post assessment, educational intervention study conducted among second year undergraduate medical students.Methods: Second year medical students were randomly selected and assigned to two groups A (Cross word puzzle) and B (control), after an hour conventional lecture on “Drugs for Hypertension” In both the groups, pre- and post-intervention knowledge was assessed using the MCQ test. A self-designed crossword puzzle on the lecture topic was used as an intervention and students were allowed to read textbooks with a crossword puzzle in intervention group A, whereas control group B were allowed to read textbook only. After 45 minutes, the post-intervention assessment was done in both groups with the same set of MCQ and students’ feedback on crossword usefulness was obtained.Results: The average MCQ test score in Group A improved significantly from 6.65±3.4 pre-intervention to 11.26±2.5 post-intervention (p <0.05) with absolute learning gain 30.73 % and relative learning gain 69.32 %. The average test score in Group B also improved significantly from 5.7±2.9 pre-intervention to 9.59±2.5 post-intervention (p <0.05) with absolute learning gain 25.93 % and relative learning gain 68.23%. There was a significant improvement in the MCQ scores in both the groups after intervention. But the post-intervention MCQ scores in group A (crossword puzzle) was higher and statistically significant (P <0.05) in comparison to group B.Conclusions: Cross-word puzzle promotes active self-learning and develops critical thinking among medical students. It could be used as supplementary educational tool in pharmacology to enhance problem-solving skills along with the information provided through traditional teaching lectures or could be used as a micro task

Effect of periodontal therapy on maxillary sinus mucous membrane thickening in chronic periodontitis: A split-mouth study

Background. This study evaluated the effect of periodontal therapy on mucous membrane thickening in maxillary sinus in chronic periodontitis patients using radiovisiography (RVG) and cone-beam computed tomography (CBCT). Methods. The study population included 30 patients diagnosed with chronic periodontitis, exhibiting bilateral mucosal thickening of maxillary sinus. The selected sites were randomly assigned to group I (control group - not receiving periodontal therapy) and group II (test group - receiving periodontal therapy). The clinical parameters and mucosal thickening of the maxillary sinus were evaluated at baseline and after 9 months. Results. There was a significant decrease in the PPD, CAL as well as mucosal thickening in group II while, group I showed an increase in these parameters. In group II at the end of 9 months the mean mucosal thickening reduction as assessed by CBCT was 0.76±0.18, 0.73±0.24, 0.88±0.42 and 1.13±0.43 mm at the most anterior point (AP), the most posterior point (PP), the mid-point (MP), point of maximum thickness (MT) as well as in the length of the thickened mucosal lining, respectively. Conclusion. The results of our study indicated a reduction in the mucosal thickening of the maxillary sinus after surgical periodontal therapy. The trial was registered with the Clinical Trial Registry of India (Trial REF/ 2016/02/010805)

Oral tablets were the commonest prescribed dosage form.Conclusions: Antihistaminics and antifungals dominated the prescribing pattern in this study with restraint on polypharmacy, but showed ample scope for improvement to prescribe generic and selection of essential drugs

ETIOPATHOGENESIS & SHATKRIYAKALA OF MUTRAKRUCCHA (DYSURIA ): A REVIEW STUDY

Now a days, it is seems that several patients are suffering from different types of disorders of Mutravaha Srotas. So, each physician should know the details like nidana (etiological factor), samprapti (pathogenesis), lakshanas(symptoms), sadhyaa-sadhyata (prognosis), updrava(complication), chikitsa (management) of disorders. Mutrakrucha  is one of the important disease of mutravaha srotas. The word †MUTRAKRUCHA †means dysuria is a symptom of pain , discomfort ,or burning when urinating. Cause due to infection  can occure in any part of urinary tract including kidney ,ureter , bladder, urethra. burning micturation is an cardinal features.Exercises, strong potential drugs, excessive indulgence of row alcohol, Ingestionof flesh of wet landed animals &amp; fishes, Eating again before digestion of previous food &amp; indigestion. This factors causes dushti of mutravaha srotas are also may be considered as nidana of Mutrakrucha. Due to this causative factors the doshas get aggravated.  Mutrakrichha, the vitiated Pitta Dosha along with Vata (mainly Apana Vayu) on reaching Vasti (bladder) afflicts the Mutravaha Srotas due to which the patient feels difficulty in micturition along with symptoms like Peeta mutrata, Sarakta mutrata, Sadaha mutrata, Saruja mutrata and Muhur-muhur mutrata. The above mentioned symptomatology has close resemblance with urinary tract infections. up with urine &amp; hence painful urination is accompanied by changes in urine flow such as dribbling , difficulty intiating flow , increased frequency or need to  urinate . Here due to influence over apana vata cited at Basti pradeha(Bladder)the pathology continues &amp; painful urination  is caused. here. Shatkriyakala explains the pathogenesis of a disease in stages right from the incubation period to complete manifestation &amp; later consequences of disease. Hence, I am  review this , mentioned Shatkriyakala of Mutrakrucha  which should be important to managed in early stage (sanchay avastha) and to prevent further complication

Is malaria the cause for decline in the wild population of the Indian White-backed vulture (Gyps bengalensis)?

The populations of three species of Gyps vultures have shown a decline of more than 95% between 1988 and 1999 in the Indian subcontinent and are now classified as 'critically endangered'. The indiscriminate and widespread veterinary use of diclofenac has been implicated for the decline of the White-backed vulture (Gyps bengalensis) in Pakistan, India and Nepal. Similar trends in population decline as seen in the northern regions have also been recorded in Central and South India, but the cause for the decline was not investigated. Here we report a study carried out in a densely forested and sparsely populated region in Central India. An intracellular malarial parasite was identified from the tissues of both live and dead Whitebacked vultures. Further, amplification and sequence analysis of the consensus sequence of the mitochondrial small and large sub-unit rRNA genes indicated a 95-96% similarity with the mitochondrial sequence of Plasmodium falciparum (DQ642845) and other Plasmodium species. In addition, amplification and sequencing of a 502 bp fragment of the mitochondrial cyt b gene identified the haemoprotozoan with Plasmodium sp. AP70, an avian malarial parasite. During the course of this study we also rescued two terminally ill vultures with symptoms of malaria, and treatment with anti-malarials led to their recovery. None of the affected vultures had diclofenac residues, thus implying that malaria could be an additional cause for the decline for the White-backed vulture population

Gamma Radiation Induced Formation of Iodine Monochloride in Iodine in Some Aromatic Chlorinated Solvents

Abstract: Gamma radiation induced formation of ICl in aerated and deaerated solutions of iodine in some aromatic chlorinated solvents has been studied for different concentrations and γ dosages. G values for formation of ICl and decomposition of I 2 were determined in gamma radiolysis of aerated and deaerated solutions of I 2 in 1,2-dichlorobenzene(1,2-DCB), 1,3-dichlorobenzene(1,3-DCB), 2-chlorotoluene, 3-chlorotoluene and benzotrichloride. G(ICl) values have been found to decrease in the following order 2-chlorotoluene &lt; 3-chlorotoluene &lt; 1,2-DCB &lt; 1,3-DCB &lt; benzotrichloride. G(ICl) is slightly higher in aerated solutions than in deaerated solutions and is found to be dependent on the structure of the parent organic molecule

Site selection for vascular access creation in hemodialysis in end stage renal disease

Background: Chronic kidney failure is characterized with progressive and irreversible diminishing of glomerular filtration rate. AVF has been unanimously considered the gold standard vascular access of choice for hemodialysis. Arterio-venous fistula (AVF) for hemodialysis should be created in patients with endogenous creatinine clearance < 20 mL/min/1,73m2. Aim of current study was to choose the proper site for arteriovenous fistula creation with minimal complications.Methods: It was a prospective study, carried out in the dept. of surgery from April 2008 to August 2013. A total of 140 patients were studied over the period. The fistulae were created using radial artery cephalic vein side to side and brachial artery cephalic vein side to side or end to side anastomosis. Statistical analysis used: Mean, Standard deviation, Standard error.Results: A total 140 patients were studied, out of them 104 were males and 36 were females. The radiocephalic site was used for 82 (58.57%) patients and 58 (41.43%) patients were operated on brachiocephalic site. The mean inner diameter of radial artery, brachial artery and cephalic vein (intima to intima) at elbow and wrist were 21.49001 ± 0.901 (SE - 0.28492), 3.72533 ± 1.06837 (SE - 0.30841) and 0.68079 ± 0.49551 (SE - 0.116790) respectively. The mean flows velocity of brachial and radial artery were 76.10526 ± 4.54477 (SE - 1.04264) and 52.64286 ± 5.5968 (SE - 1.495810) respectively. The success rate of AV fistula on table was 97.85% (137 out of 140). The incidence of complication was 18.57%.Conclusion: The site for fistula creation depends on the quality of the artery and vein. To achieve good success rates preoperative color Doppler is essential to evaluate the vessels. The complication rates can be minimised by following standard operating protocols.
