1.Acute pyogenic bone and joint infections.
Annals of the Academy of Medicine, Singapore 1987;16(2):252-255
Acute infections of bone and joints is a curable condition and the chance of cure is related to a number of factors like type and virulence of the organism, resistance of the host, choice of antibiotics, early drainage of the joint in septic arthritis and appropriate treatment after early diagnosis with adequate dosage and duration of antibiotic therapy. Late diagnosis and inadequate treatment can often lead to high mortality and morbidity and leave the patient with crippling sequelae like chronic osteomyelitis, joint destruction, pain, shortening, deformity and limp.

Objective: To investigate hepatoprotective activity of the methanolic extract of Fagonia indica Burm. on CCl4 induced hepatotoxicity in albino rats. Methods: Animals in Group 1 served as vehicle control, Group 2 served as hepatotoxin (CCl4 2ml/kg, s.c) treated group, Group 3 served as standard (Silymarin 50mg/kg, p.o.) treated group. Group4 and 5 served as methanolic extract of Fagonia indica (MEFI) in different doses (200 mg/kg and 400 mg/kg b.w., p.o).The degree of protection was determined by measuring levels of biochemical marker like SGOT, SGPT, ALP, Bilirubin (Total & Direct) and Cholesterol. The histopathological studies also show the hepatic protection of the test extracts. Results: The levels of the biochemical parameters such as SGPT, SGOT, ALP, Total bilirubin, Direct bilirubin and Cholesterol were significantly increased in CCl4 treated rats when compared with the normal group (P<0.05), but the MEFI (400 mg/kg, bw) treated rats showed maximum reduction of SGOT (114.83±1.51), SGPT (164.33±1.25), ALP (154.83±1.53), Total bilirubin (1.55±0.01), Direct bilirubin (0.65±0.009) and Cholesterol (193.00±1.06) in a significant manner. Histopathological studies also reveal the hepatoprotection property of MEFI in a dose dependent manner. Conclusions: These results suggest that MEFI in different doses showed significant hepatoprotective activity against CCl4 induced hepatotoxicity and this might be due to the presence of flavonoids and tannins. Further research is sought to explore the exact mechanism of action and phytoconstituents responsible for the pharmacological response.

Unilateral adrenalectomy was performed in six black Bengal goat (Capra hircus)to study electrocardiograph in connection with mineral metabolism with special reference to sodium and potassium and some other factors of physiological importance. The parameters were studied at every 12 hrs interval upto 120 hrs and 24 hrs interval from 120 to 240 hrs.Physiological parameters, like body weight and rectal temperature, changed non-significantly (p<0.05)after adrenalectomy. Among minerals, plasma sodium (p<0.01)and plasma potassium (p<0.05) concentration were changed significantly between hours leaving impression in ECG as widening of QRS complex and peaked T wave with increased amplitude found after unilateral adrenalectomy. Heart rate also increased significantly (p<0.01)between hours.

Background:
Hemophilia B (HB) is an X-linked bleeding disorder resulting from coagulation factor IX defects. Over 3,000 pathogenic, HB-associated mutations in the F9 gene have been identified. We aimed to investigate the role of F9 variants in 150 HB patients using sequencing technology.
Methods:
F9 gene sequences were amplified from peripheral blood-derived DNA and sequenced on an Applied Biosystems (ABI) 3500 Sanger sequencing platform. Functional and structural predictions of mutant FIX were analyzed.
Results:
Among 150 HB patients, 102 (68%), 30 (20%), and 18 (12%) suffered from severe, moderate, and mild HB, respectively. Genetic analysis identified 16 mutations, including 3 novel mutations. Nine mutations (7 missense and 2 stop-gain) were found to be pathogenic.Only 3 mutations (c.127C>T, c.470G>A, and c.1070G>A) were associated with different severities. While 2 mutations were associated with mild HB cases (c.304C>T and c.580A>G), 2 (c.195G>A and c.1385A>G) and 3 mutations (c.223C>T, c.1187G>A, and c.1232G>A) resulted in moderate and severe disease, respectively. Additionally, 1 mutation each was associated with mild-moderate (c.*1110A>G) and mild-severe HB disease (c.197A>T), 4 mutations were associated with moderate-severe HB cases (c.314A>G, c.198A>T, c.676C>T, and c.1094C>A). FIX concentrations were lower in the mutated group (5.5±2.5% vs. 8.0±2.5%). Novel p.E66D and p.S365 mutations were predicted to be pathogenic based on changes in FIX structure and function.
Conclusion
Novel single nucleotide polymorphisms (SNPs) largely contributed to the pathogenesis of HB. Our study strongly suggests that population-based genetic screening will be particularly helpful to identify risk prediction and carrier detection tools for Indian HB patients.

Vertebrovertebral arteriovenous fistulas (VVAVFs) are rare entities that lack consensus guidelines for their management. Our case describes the successful treatment of a traumatic VVAVF via a contralateral deconstructive endovascular approach. A 64-year-old female presented following a traumatic fall. Computed tomography angiogram highlighted a 2 cm pseudoaneurysm of the right vertebral artery (VA) with epidural contrast enhancement and a hematoma with flow voids within the epidural space. Digital subtraction angiography showed a VVAVF at C2-3 with retrograde filling of the distal right VA. Having undergone several unsuccessful passes of the proximal dissection flap in the right VA, the patient underwent a contralateral deconstructive approach with correction of the VVAVF without complication. The remaining feeding branches had occluded after 1 week. The patient made a complete recovery without neurological sequelae at 3-month follow-up.

Autism is a complex neurodevelopmental disorder, the prevalence of which has increased drastically in India in recent years. Neuroligin is a type I transmembrane protein that plays a crucial role in synaptogenesis. Alterations in synaptic genes are most commonly implicated in autism and other cognitive disorders. The present study investigated the neuroligin 3 gene in the Indian autistic population by sequencing and in silico pathogenicity prediction of molecular changes. In total, 108 clinically described individuals with autism were included from the North Karnataka region of India, along with 150 age-, sex-, and ethnicity-matched healthy controls. Genomic DNA was extracted from peripheral blood, and exonic regions were sequenced. The functional and structural effects of variants of the neuroligin 3 protein were predicted. One coding sequence variant (a missense variant) and four non-coding variants (two 5'-untranslated region [UTR] variants and two 3'-UTR variants) were recorded. The novel missense variant was found in 25% of the autistic population. The C/C genotype of c.551T>C was significantly more common in autistic children than in controls (p = 0.001), and a significantly increased risk of autism (24.7-fold) was associated with this genotype (p = 0.001). The missense variant showed pathogenic effects and high evolutionary conservation over the functions of the neuroligin 3 protein. In the present study, we reported a novel missense variant, V184A, which causes abnormal neuroligin 3 and was found with high frequency in the Indian autistic population. Therefore, neuroligin is a candidate gene for future molecular investigations and functional analysis in the Indian autistic population.
