Cerebellum is unique in restraining amyloid-induced neurodegenerative changes. Amyloidosis and oxidant imbalance is common in aluminum exposure. Interestingly, aluminum itself does not pose any redox activity still it is associated with oxidant imbalance, and, it can aggravate the situation of already existing oxidant threat. Male rats were exposed to aluminum for 4 weeks along with exposure to 4 different doses of ethanol. After the treatment period, cerebellar level of protein, reduced glutathione (GSH), lipid perioxidation (TBARS) were measured. Activities of catalase, superoxide dismutase (SOD), glutathione reductase (GR) and glutathione perioxidase (GPx) were also estimated from the homogenized cerebellar tissue. In the present regimen of aluminum exposure, the cerebellum has shown significant reduction only in GPx activity. However, when aluminum was coexposed with ethanol, it contributed significantly to increase the cerebellar oxidant imbalance by (a) compromising the GSH restoration system, (b) reducing enzymatic peroxide scavenging system of cerebellum, (c) restricting the capability to cope with oxidative stress, as well as (d) downgrading the resistance to oxidative damage in response to chemical stress. Present study demonstrates that coexposure of aluminum with pro-oxidant favored development of aluminum-induced oxidative stress in cerebellum. These observations enlighten the role of pro-oxidants in the process of oxidative degeneration of cerebellum. With further studies, the present observation can be useful to understand the mechanism of neurodegenerative disorders and ways to ameliorate them. © 2012 Pleiades Publishing, Ltd.

Background: Negative pressure wound therapy (NPWT) is an established modality in the treatment of chronic wounds, open fractures, and post-operative wound problems. This method has not been widely used due to the high cost of equipment and consumables. This study demonstrates an indigenously developed apparatus which gives comparable results at a fraction of the cost. Readily available materials are used for the air-tight dressing.Materials and Methods: Equipment consists of suction apparatus with adjustable pressure valve set to a pressure 125-150 mmHg. An electronic timer switch with a sequential working time of 5 min and a standby time of 3 min provides the required intermittent negative pressure. Readily available materials such as polyvinyl alcohol sponge, suction drains and steridrapes were used to provide an air tight wound cover.Results: A total of 90 cases underwent 262 NPWT applications from 2009 to 2014. This series, comprised of 30 open fractures, 21 post-operative and 39 chronic wounds. The wound healing rate in our study was comparable to other published studies using NPWT.Conclusion: The addition of electronic timer switch will convert a suction apparatus into NPWT machine, and the results are equally effective compared to more expensive counter parts. The use of indigenous dressing materials reduces the cost significantly.

Oxidant imbalance is one of the causative mechanisms of aluminum-induced neurotoxicity. In this study, we investigated aluminum-induced oxidant imbalance in non-neuronal tissues (liver, kidney and testis) and temporal cortex in rats. The differences in adaptations to superoxide and peroxide handling capacities (SPHC) of studied organs due to aluminum insult were also evaluated. Male Wistar rats were exposed to aluminum (10 mg/Kg body wt/day) for 4 weeks through orogastric intubation. Liver showed significant decrease in reduced glutathione level, while significant alteration in lipid peroxidation was observed in temporal cortex in aluminium-exposed animals. Superoxide dismutase activity was significantly altered in liver and temporal cortex and catalase activity significantly reduced in the liver due to aluminum exposure, while glutathione reductase and glutathione peroxidase activities were altered in all the tested organs. Among the organs, glutathione-independent SPHC was relatively higher in liver and kidney, while glutathione-dependent SPHC was relatively higher in testis and temporal cortex. As compared to control, aluminum-exposed rats demonstrated reduction in glutathione-dependent SPHC in temporal cortex and increment of the same in testis, while increment in glutathione- independent SPHC was observed in liver. In conclusion, aluminum-induced alteration in oxidant handling capacity could be the cause of oxidative stress both in the neuronal and non-neuronal tissues.

The objective of the present study is to study the prevalence of sub clinical hypothyroidism and its association with dyslipidemia. Thyroid hormone maintains the development and metabolism of the body. Thyroid dysfunction has been associated with complications like infertility, diastolic hypertension, ischemic heart disease, psychiatric disorders. 1157 subjects attending the NRI Hospital, Guntur for routine check up were taken into study. The patients were not under any medication. TSH and lipid profile was determined for all the subjects. The thyroid screening was done on Centaur CP and lipid profile on Dade Behring auto analyzer. FT 4 was estimated in subjects with TSH level 5.5 to 10μIU/ml to confirm SCH. Result: The prevalence of Sub clinical Hypothyroidism (SCH) was 8.29% and the SCH was associated with increased dyslipidemia. Total cholesterol, triglyceride, LDL were raised up to 317 mg/dl, 575mg/dl and 201mg/dl respectively. TSH level significantly correlated with total cholesterol and LDL cholesterol.

Superoxide and peroxide handling capacity (SPHC) is an important determinant of oxidative stress. Neurotoxic impacts of aluminum are associated with oxidant imbalance. Here, we studied the influence of aluminum on oxidative stress parameters, antioxidative enzymes and SPHC of thalamic area on pro-oxidant (ethanol) and antioxidant (α-tocopherol) exposure. Two sets of male Wistar rats were divided into 8 groups (6 each) and exposed to aluminum (10 mg/Kg body wt.), ethanol (0.6 g/Kg body wt.) and α-tocopherol (5 IU/day) for 4 wk, each having respective control group. Levels of reduced glutathione (GSH), lipid peroxidation (TBARS) along with activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and glutathione reductase (GR) of thalamic area were estimated for each group. Glutathione-independent superoxide peroxide handling capacity (GI-SPHC) and glutathione-dependent superoxide peroxide handling capacity (GD-SPHC) were calculated from the GPx, CAT and SOD values. Concomitant exposure to aluminum and ethanol demonstrated significant increase in SOD activity and significant decrease in GPx activity compared to the control group, while lone aluminum-exposed rats showed raised GR activity, without alterations in GPx and SOD activities. However, significant reduction of both GI- and GD- SPHC were found in ethanol-exposed groups. α-Tocopherol supplementation could resist most of the alterations. In addition, current antioxidant exposure reduced the inherent GD-SPHC, and thus, made thalamic area more vulnerable to oxidant threat. The present study corroborates the thalamic susceptibility to aluminum-augmented oxidant imbalance and suggests cautious use of antioxidant supplementation against neurodegenerative disorders. © 2015, National Institute of Science Communication.

Encephalocraniocutaneous lipomatosis (ECCL) is a rare sporadic neurocutaneous syndrome characterized by presence of central nervous system, ocular and cutaneous anomalies. The exact pathogenesis is still not known. We present the third case from the Indian subcontinent, who is a five year old girl with history of right sided seizures. Dermatological examination showed alopecia on right side of the scalp and ipsilateral limbal dermoid and nodular skin tags over the upper eyelid. The computerized tomography scan of the brain revealed porencephalic cyst, cerebral calcifications and atrophy of right brain. The histopathology of the skin lesions showed lipomatous hamartoma and features of non scarring alopecia. The constellation of these findings and in adherence to the diagnostic criteria of ECCL proposed in 2009, we consider this report as a definite case of ECCL. © Indian Journal of Dermatology 2013.

Ubiquitous presence along with uncontrolled use of aluminum and increasing trends of ethanol consumption in India increased the chance of coexposure to aluminum and ethanol. Possibilities are there, that both of them follow common mechanisms to produce neurotoxicity. The phosphomonoesterases and glutamate transaminases are studied in rat brain cerebrum after combined exposure to aluminum and varied doses of ethanol for 4 weeks. Dose dependent decreases in growth have been observed. The impact of aluminum on cerebral acidic and alkaline phosphomonoesterases activities were shown to be altered in a dose dependent fashion by the coexposure to ethanol. Aspartate aminotransferase and alanine aminotransferase of the cerebrum were responding differentially to aluminum exposure in the presence of different doses of ethanol exposure. It has been suggested that the ethanol-induced augmentation of impacts of aluminum on the cerebrum is dose dependent and there might be a critical level of ethanol exposure for the observed effect on cerebrum.

A 35-year-old male presented with pain and swelling of his right foot and ankle. His pain developed gradually and without overt pedal deformity. The radiologic examination revealed complete fusion of all tarsal bones of his right foot. Comparative radiographs of his left foot also showed complete tarsal coalition. Ankle osteoarthritis was diagnosed, and supportive treatment enabled the patient to return to an asymptomatic status and continue the duties of his employment. This case is presented to describe an adult patient with bilateral, massive tarsal coalition who was essentially asymptomatic until degenerative arthritic changes developed in one of his ankles.

Synovial chondromatosis is a rare, generally benign condition which affects the synovial membranes and commonly involves the large joints such as the knee, and hip. It is usually mono-articular and more common in males. Synovial chondromatosis is characterized by the presence of multiple cartilaginous nodules in the joint synovium. The definitive diagnosis is achieved after the pathological examination of the synovial tissue. It can be very destructive and can cause severe osteoarthritis, pain and malignant transformation. We present a rare case of primary synovial chondromatosis of the shoulder joint in a 31-year-old male patient.A 31-year-old man presented with pain and restricted movements of left shoulder for past 6 months, which was insidious in onset and gradually progressive. He had no history of trauma, fever, loss of appetite or weight loss. No tenderness or warmth over shoulder joint was observed. Restriction of movements was observed in all directions. No abnormality was detected in central nervous, cardiovascular, respiratory, genitourinary, or gastrointestinal systems. Routine pre-operative investigations (including liver function and renal function tests) were within the normal limit, serological investigation for rheumatoid arthritis was negative. Excision biopsy of loose bodies was performed. Biopsy reported histological features ofsynovial chondromatosis.Synovial osteochondromatosis of shoulder joint, subscapular recess and along the long head of biceps is a rare case (less than 5% cases reported till date). Understanding the pathology, recognizing the radiographic and MRI appearance of primary synovial chondromatosis and differentiating it from secondary form, malignancy and other synovial pathologies are important in the diagnosis and clinical management of these patients.
