Sarcomatous Transformation of Recurrent Scapular Osteochondroma in a Patient with the Hereditary Multiple Osteochondromas: A Case Report and Literature Review.

Hereditary multiple osteochondromas (HMO) is an autosomal dominant disease diagnosed by the presence of two or more than two osteochondromas on radiographs. The majority of cases are asymptomatic. The presence of bony growth, pain, and compression of the surrounding structure are the usual presentations. Malignant transformation into chondrosarcoma is the most feared complication. A rapid increase in size, recurrence after the surgical excision, and infiltrating mass may suggest the conversion into chondrosarcoma. Radiological imaging helps in diagnosing malignant transformation. MRI is the investigation of choice to exclude cancer. We hereby present a case of multiple osteochondromas with suspected malignant transformation due to rapidly increasing painful osseous swelling.

Expression kinetics of natural resistance associated macrophage protein (NRAMP) genes in Salmonella Typhimurium-infected chicken.

BACKGROUND: Salmonella enterica serovar Typhimurium (Salmonella Typhimurium) is a zoonotic pathogen responsible for severe intestinal pathology in young chickens. Natural resistance-associated macrophage protein (NRAMP) family has been shown to be associated with resistance to intracellular pathogens, including Salmonella Typhimurium. The role of NRAMP proteins in macrophage defence against microbial infection has been ascribed to changes in the metal-ion concentrations inside the bacteria-containing phagosomes. The present study was conducted to investigate tissue-specific (liver, spleen and caecum) expression kinetics of NRAMP gene family (NRAMP1 and NRAMP2) in broilers from day 0 to day 15 after Salmonella Typhimurium challenge concomitant to clinical, blood biochemical and immunological parameters survey. RESULTS: Clinical symptoms appeared 4 days post-infection (dpi) in infected birds. Symptoms like progressive weakness, anorexia, diarrhoea and lowering of the head were seen in infected birds one-week post-infection. On postmortem examination, liver showed congestion, haemorrhage and necrotic foci on the surface, while as the spleen, lungs and intestines revealed congestion and haemorrhages. Histopathological alterations were principally found in liver comprising of necrosis, reticular endothelial hyperplasia along with mononuclear cell and heterophilic infiltration. Red Blood Cell (RBC) count, Haemoglobin (Hb) and Packed Cell Volume (PCV) decreased significantly (P < 0.05) in blood while heterophil counts increased up to 7 days post-infection. Serum glucose, aspartate transaminase (AST) and alanine transaminase (ALT) enzymes concentrations increased significantly throughout the study. A gradual increase of specific humoral IgG response confirmed Salmonella infection. Meanwhile, expression of NRAMP1 and NRAMP2 genes was differentially regulated after infection in tissues such as liver, spleen and caecum known to be the target of Salmonella Typhimurium replication in the chicken. CONCLUSION: Thus the specific roles of NRAMP1 and NRAMP2 genes in Salmonella Typhimurium induced disease may be supposed from their differential expression according to tissues and timing after per os infection. However, these roles remain to be analyzed related to the severity of the disease which can be estimated by blood biochemistry and immunological parameters.

Effect of Naringenin (A naturally occurring flavanone) Against Pilocarpine-induced Status Epilepticus and Oxidative Stress in Mice.

BACKGROUND: Epilepsy is a disorder of the central nervous system characterized by recurrent seizures. It is a very common disease in which approximately 30% of patients do not respond favourably to treatment with anticonvulsants. Oxidative stress is associated with neuronal damage arising from epileptic seizures. The present study investigated the effects of naringenin in pilocarpine-induced epilepsy in mice. Naringenin, one of the most frequently occurring flavanone in citrus fruits, was evaluated for its shielding effect against the pilocarpine induced behavioural, oxidative and histopathological alterations in rodent model of epilepsy. METHODOLOGY: Epilepsy was induced by giving pilocarpine (300mg/kg) and sodium valproate (300mg/kg) was given as standard anti-epileptic drug Pilocarpine was administered (300 mg /kg body weight) intraperitoneally to the mice on 15th day while naringenin was administered orally (20 and 40 mg/kg body weight) for 15 days prior to administration of pilocarpine. RESULTS: The intraperitoneal administration of pilocarpine enhanced lipid peroxidation, caused reduction in antioxidant enzymes, viz., catalase, superoxide dismutase and glutathione reductase. Treatment of mice orally with naringenin (20 mg/kg body weight and 40 mg/kg body weight) resulted in a significant decrease in lipid peroxidation. There was significant recovery of glutathione content and all the antioxidant enzymes studied. Also in case of behavioural parameters studied, naringenin showed decrease in seizure severity. All these changes were supported by histological observations, which revealed excellent improvement in neuronal damage. CONCLUSION: The higher dose of naringenin was more potent in our study and was comparable to the standard drug (sodium valproate) in effectiveness. SUMMARY: Naringenin ameliorated the development of ROS formation in hippocamus.Naringenin helped in recovery of antioxidant enzymes.Naringenin decreased seizure severity.Naringenin treatment reduced lipid peroxidation.

Histomorphological studies of broiler chicken fed diets supplemented with either raw or enzyme treated dandelion leaves and fenugreek seeds.

AIM: Herbal plants and their derived products are extensively used particularly in many Asian, African, and other countries of the world as they are considered as ideal feed additives because of their non-residual effect and ability to influence the ecosystem of gastrointestinal microbiota in a positive way. Further, the enzymatic treatment of these herbs helps in their efficient utilization by the host. Dandelion leaves and fenugreek seeds have been reported to have positive effect in terms of improving the performance of broiler chicken, but not much literature is available regarding their effect on gut histomorphology; therefore, the present study was conducted to explore the effect of these herbs either alone or in combination with or without enzyme treatment on histomorphology of liver and small intestine of broiler chicken. MATERIALS AND METHODS: To achieve the envisaged objective, 273-day-old commercial broiler chicks were procured from a reputed source and reared together until 7 days of age. On the 7(th) day, the chicks were individually weighed, distributed randomly into 7 groups of 3 replicates with 13 chicks each. Birds in the control group were fed diets without additives (T1). The other six treatment groups were fed the basal diet supplemented with 0.5% dandelion leaves (T2), 1% fenugreek seeds (T3), combination of 0.5% dandelion leaves and 1% fenugreek seeds (T4), enzyme treated dandelion leaves 0.5% (T5), enzyme treated fenugreek seeds 1% (T6), and combination of enzyme treated dandelion leaves (0.5%) and (1%) fenugreek seeds (T7). The histomorphological study of liver and small intestines was conducted among different treatment groups. RESULTS: The results revealed the hepato-protective nature of both dandelion leaves and fenugreek seeds either alone or in combination with or without enzyme treatment when compared with the control group. Moreover, the histomorphological findings of jejunum revealed the beneficial effect of dandelion leaves, fenugreek seeds and enzymes on the intestinal mucosa in terms of cellular infiltration, architecture of villi, villus height/crypt depth ratio, thereby improving the intestinal health. CONCLUSION: The dandelion leaves and fenugreek seeds have hepato-protective nature and beneficial effect on the intestinal morphology particularly when included along with enzymes in the diet of broiler chicken.

An unusual vesical calculus.

We report a 52 year old patient presenting with a bladder stone formed over a migrated intrauterine device (Copper-T). Her history was pertinent for intrauterine contraceptive (IUCD) device placement 10 years back. Investigations included plain ultrasound of abdomen, X-ray of abdomen, urinalysis, and urine culture. Ultrasound and plain X-ray of the pelvis confirmed a bladder stone formed over a migrated copper-T intrauterine device. The device was removed through suprapubic cystolithotomy. Of all the reported cases of vesical stone formation over a migrated IUCD, this case is unique as the patient was an elderly - 52 year old - female. All previously reported cases are of younger age.

Cystic hygroma--an unusual cause of induced abortion.

A male infant was diagnosed prenatally at 20 weeks of gestation with posterior cervical cystic hygroma. The mother was a 31-year-old gravida, who had an otherwise normal systemic examination. A therapeutic abortion was arranged and fetus was aborted. Sonographic findings were confirmed on examination of aborted fetus
