Evaluation of prostate-specific antigen and total serum acid phosphatase in prostatic carcinoma

Background: The importance of prostatic carcinoma and its detection has increased manifold over the last few decades. Total serum acid phosphatase (ACP) was the world’s first emerged clinically useful tumor marker in the 1940s and 1950s in patients with prostatic diseases. With the introduction of the prostatic specific antigen (PSA) test in the 1980s, which performed significantly better in screening and treatment programs bringing disfavor to the advent of ACP. Aims and Objectives: To determine serum PSA and total serum ACP in patients with prostatic cancer and benign prostatic diseases, followed by evaluation of these tumor markers. Materials and Methods: This study was conducted on 30 patients with histologically proven cases of prostatic carcinoma and compared against 30 patients as control with benign prostatic pathology, residing in Punjab who were admitted and treated with symptoms complex of prostatism or retention urine or other urinary complaints as the primary symptoms. PSA and ACP in serum were determined using ELISA test kit and King and Kind method, respectively. Results: The mean level of serum PSA was 81.19 ± 49.02 for cancer prostate and 4.975 for benign prostatic diseases, while the mean level of serum ACP was 5.22 ± 1.70 and 2.52 ± 2.27, respectively, for the cancer prostate and benign prostatic diseases showing statistically difference between study and control groups was highly significant as P < 0.0001. Conclusion: Statistical analysis and results of the present study indicated that although serum ACP has better specificity to PSA, yet later is a very sensitive tumor marker in prostate diseases for screening, diagnosis, and post-treatment follow-up.

Short Communication Infodemic: The epidemic of information during COVID-19

India is one of the world抯 worst affected countries due to COVID-19 pandemic. The world is struglling to fight agaisnt centuries pandmemic. Globally goverments have been imposed lockdown and restrictions to control situation and minimise spread of infection. Social media was found the most practical and efficiant mediam to share information and opnions about pandmemic. At time of social distancing, social media helped people to share their feelings and find support. Same time overuse of social media palteform created panic and misinformation across countries. People sharing unconfirmed information about covid pandmemic and goverments were found it difficult to handle

Effect Of Photodynamic Therapy In The Management Of Periodontal Disease - A Systematic Review

Background:Periodontitis is multifactorial disease which is initiated with plaque formation that will initiate an inflammatory response which can cause destruction of tissues & tooth supporting structure. If left untreated it will cause gingival recession and bone destruction which will lead to tooth mobility. Sometimes it is difficult to eliminate periodontal pathogens completely from deepest areas of periodontal pockets, to overcome these issues photodynamic therapy (PDT) was used as it is local non-invasive treatment modality without any side effects. Aim:The aim of present study was to investigate the effectiveness of Photodynamic Therapy (PDT) as an Adjunct To Scaling & Root Planing in the managementOf Periodontal Disease. Material And Methods:Literature was searched systemically and studies were identified based on the-PICO (Glossary of Evidence Based Terms 2007). Electronic database search of Pubmed, Google scholar, Medline and scopus was performed using (MESH) terms-Photodynamictherapy,periodontitis, microbiological assessment. Articles published between year 2009-2019 were reviewed. Patient treated with SRP alone on one side and other side with SRP+ PDT. Recording of Clinical parameters like PPD,CAL,BOP,PS,GR were done from baseline to 3,6 month. Microbiological and biochemical analysis were also evaluated to check level of RANKL/OPG, IL-1?, TNF-?, Aggregatibacter actenomycetocomitans, Porphyromonas gingivalis, Tanerella forsythia Conclusion::A large evidence suggest that PDT when used along with SRP resulted in significantimprovement in clinical parameters.Significant improvement in biochemical parameters such as IL-1? , Tnf-? , RANKL/OPG were also seen after periodontal therapy along with PDT when compared with SRP alone.

Primitive neuroectodermal tumors of kidney: Our experience in a tertiary care center.

OBJECTIVES: Primitive neuroectodermal tumors (PNET) are rare highly aggressive neoplasms. The diagnosis is made by histopathology with the support of immunohistochemistry (IHC) and cytogenetics. The aggressive multimodality treatment is recommended for the management of these tumors. The purpose of our study is to review our experiences in the diagnoses and treatment of PNET of the kidneys. MATERIALS AND METHODS: We retrospectively reviewed the data of all the patients, who were treated for the PNET of the kidneys at our institute between April and March 2011 and compared with the available literature. RESULTS: A total of eight patients were treated for PNET of the kidney. Out of the eight patients, four were males and four females. Nearly 50% of our patients had inferior vena caval thrombus at the time of presentation. The diagnosis was made on histopathology supported by IHC. Out of the eight patients, one patient had intraoperative death due to massive pulmonary thromboembolism and another died on the 7th post‑operative day due to disseminated intravascular coagulation and multiorgan failure. Rest six patients were treated with post‑operative chemotherapy or a combination of chemotherapy and radiotherapy. For these six patients, overall median survival was 45 months with a 3 year disease‑free survival of 66% and 5 year survival of 44%. CONCLUSIONS: PNET of the kidneys are rare peripheral neuroectodermal tumors with an aggressive clinical course. These tumors carry a very poor prognosis. An aggressive treatment approach using a combination of surgery, chemotherapy and radiotherapy is recommended for a reasonable survival in these tumors.

Protective efficacy of Emblica officinalis against Klebsiella pneumoniae induced pneumonia in mice.

BACKGROUND & OBJECTIVES: Emblica officinalis (amla), which is a good source of vitamin C, has been shown to be beneficial due to its immune system enhancing property coupled with its tonifying and antiageing effect. The present study was conducted to evaluate the effect of E. officinalis feeding on the susceptibility of experimental mice to respiratory tract infection induced by Klebsiella pneumoniae. METHODS: The effect of short- (15 days) and long (30 days)-term feeding of amla in mice on the course of K. pneumoniae ATCC43816 infection in lungs was studied, in terms of bacterial colonization, macrophage activity, malondialdehyde (MDA) and nitrite production in broncheoalveolar lavage fluid (BALF). Tumour necrosis factor (TNF)-alpha level in serum was also assessed. RESULTS: Though there was a decrease in bacterial colonization after short-term feeding, it was not significant. On the contrary, the decrease in bacterial load was significant (P < 0.05) on long-term feeding. The operative mechanisms in terms of lipid peroxidation, phagocytosis and nitrite production were studied by estimating their levels in broncheoalveolar lavage fluid (BALF). Maximum decrease in malondialdehyde (MDA) levels and increase in phagocytic activity and nitrite levels on long-term feeding was seen. INTERPRETATION & CONCLUSION: These results suggest that dietary supplementation with amla protects against bacterial colonization of lungs on long-term feeding in experimental model. Further studies need to be conducted to understand the actual mechanism.

Comparison of sealing efficacy of materials placed in lateral root perforations--an in vitro study.

An endodontic perforation interferes with the principal goal of sealing the root canal system. An in vitro study was conducted on comparative efficacy of three materials-Dispersalloy, Cavit and Prisma VLC Dycal when placed in lateral root perforations in cervical third areas. Root canals were prepared and irrigated thoroughly. Perforations were made with No. 2 round bur and sealed with Dispersalloy, Cavit and Prisma VLC Dycal. Dispersalloy Group I showed best sealing ability. Prisma VLC Dycal Group I too was comparable to Dispersalloy Group I in its sealing ability, followed by Cavit Group II, Prisma VLC Dycal Group II, Dispersalloy Group II in that order. Cavit Group I was least effective in sealing perforations.

Effect of vitamin D supplementation in lactating rats on the neonatal growth.

In lactating rats consuming a commercial diet adequate in calcium, phosphorus and vitamin D, the effect of supplementation of 3000 IU and 7,500 IU of vitamin D3 on the lactational performance of the dams and soft tissue and skeletal growth in the pups has been investigated. On 28th day of age, the pups in the supplemented groups were significantly heavier than in the control group. Study of the indices of cellular growth in the liver and gastrocnemius muscle revealed that the increase in the soft tissue weight was due to a significant increase in protein, RNA and DNA contents (cellular hyperplasia) without any change in protein/DNA ratio (cell size). In the tibia, compared to controls, the dry bone weight and ash weight were more in the supplemented groups, but ash weight/dry bone weight ratio was not altered. The improvement in the neonatal growth was most probably due to the greater milk yield observed in the dams in supplemented groups and not due to any anabolic effect in the pups since direct administration of 500 IU or 1,000 IU of vitamin D3 in 10 day old pups did not increase their body weight.

Effects of feeding low protein diet with and without leucine supplementation on protein status of lactating females and their pups.

Female rats were fed low protein diet (10% casein) either as such or supplemented with 3% leucine during pregnancy and lactation. Changes in litter size and the survival rate, growth and protein status of the pups were noted. The milk yield and hepatic and mammary gland protein status of the mothers were also studied. Feeding low protein diet reduced litter size, increased their mortality and resulted in poor growth of the pups. It also resulted in poor hepatic and mammary gland protein status of the mothers, as well as reduced their milk yield. On adding 3% leucine to 10% casein in the diet, the changes observed in the low protein group, did not alter in any manner.

Adrenocortical involvement in aluminium phosphide poisoning.

The effect of aluminium phosphide (AlP) which is a systemic poison on the adrenal cortex was studied in 30 patients of AlP poisoning. A significant rise in the plasma cortisol level (greater than 1048 nmol/l) was observed in the twenty patients. Mortality was 50 per cent. Autopsy study could be undertaken only in 10 patients. Histopathology showed mild to moderate changes. In the rest (10 patients), the adrenal cortex was critically involved and the cortisol level failed to rise beyond normal levels (less than 690 nmol/l). The histopathology revealed severe changes (complete lipid depletion, haemorrhage, necrosis etc.) and all these patients died. In the critically ill patients, the cortisol levels remained low because of severe adreno-cortical involvement. The changes in the adrenal cortex could be due to shock or to cellular toxic effect of phosphine. The histopathological changes in various viscera showed congestion, edema and cellular infiltration. In the heart, there were patchy areas of necrosis, while the liver showed fatty changes and the lungs showed, in addition areas of gray/red hepatization. There was no adrenal apoplexy or extensive haemorrhage that could explain shock in these patients. Cardiogenic shock could not be confirmed due to lack of facilities for haemodynamic monitoring, but there was histopathological evidence in support of cardiovascular shock.

Effect of acute environmental heat stress on urinary water and electrolyte excretion in the rat.

Plasma cortisol and urinary excretion of water, sodium, potassium, calcium and magnesium have been studied in the rat after application of heat stress. There was a significant increase in plasma cortisol level after exposure to heat. During heat stress complete cessation of urine formation was observed. In the next 30 min there was statistically significant increase in the urinary excretion of water, sodium and calcium but not of potassium and magnesium. Urinary calcium/magnesium ratio was also significantly elevated. The increase in urinary water and electrolyte excretion seemed to be mediated through prostaglandins since it could be abolished by administration of indomethacin prior to the application of heat stress. On the basis of these results, the possible role of heat stress in the genesis of urolithiasis has been discussed.

Effect of dietary restriction with and without leucine supplementation on hepatic protein status in rats.

In the present study effect of dietary restriction with and without leucine supplementation was observed on body and liver weights, and liver protein status, in adult rats. Animals were fed on two diets ad lib or were on 50 per cent and 25 per cent intakes. Dietary restriction resulted in loss of body and liver weights, hepatic protein, free-alpha-amino nitrogen and RNA contents and liver cell size (liver weight/DNA ratio). When compared with the control group, the decrease in these parameters was more in the dietary restricted leucine supplemented group. However, hepatic DNA content was not changed with the change in dietary regimen. The results suggest that leucine supplementation with dietary restriction may be more harmful for the animal than dietary restriction alone.

Adenosine deaminase activity in leprosy (a preliminary study).

Adenosine deaminase (ADA) activity was studied in 25 patients having different types of leprosy and 25 healthy volunteer as control. There was definite rise of ADA activity in BL (72.9 +/- 6.85), LL (56.7 +/- 3.35) and BT (39.1 +/- 8.28) which was statistically significant when compared to ADA activity in healthy control (9.7 +/- 0.53).

Acute effects of neurogenic stress on urinary electrolyte excretion.

Plasma Cortisol and urinary excretion of water, sodium, potassium, calcium and magnesium have been studied in the rat after application of 2 types of neurogenic stress:--(a) tight rubber band tourniquet and (b) electric shock. Plasma cortisol levels increased significantly after application of either type of stress. During both type of stress, there was statistically significant increase in the urinary excretion of water, sodium and calcium but not of potassium and magnesium. Urinary calcium/magnesium ratio was also significantly elevated. The results suggest that stress may be one of the factors involved in the genesis of urolithiasis.
