Infective Endocarditis by Pseudomonas Species Following Percutaneous Transluminal Mitral Commissurotomy.

Infective mitral valve endocarditis developed in a 35-year-old male patient after a percutaneous transvenous mitral commissurotomy (PTMC). The echocardiogram demonstrated vegetation in the anterior leaflet of the mitral valve and blood culture showed growth of Pseudomonas species which was sensitive to Ceftazidime, Ciprofloxacin, Cotrimoxazole and Imipenem and resistant to Amikacin, Ceftriaxone, Gentamycin and Nitilmycin. The patient underwent treatment with intravenous ceftazidime and ciprofloxacin for six weeks and patient improved significantly and got cure of the disease. Infective mitral valve endocarditis should be recognized as a potentially lethal complication after PTMC. The important measures to prevent bacteremia during PTMC and the appropriate role of antibiotics and operation are discussed

Complementary and Alternative Medicine in Cardiovascular Care.

Complementary and alternative medicine (CAM) refers to a broad set of health care practices that are not part of a country’s own tradition and are not integrated into the dominant health care system. Herbal remedies, dietary supplements, acupuncture, homeopathy, ayurveda, unani, traditional Chinese medicine, prayer, yoga and meditation are the common examples. CAM therapies often represent an enormous area of unregulated and widely practised therapeutics with an inadequate scientific literature. However, there is emerging evidence that some of the CAM therapies are effective in certain clinical conditions. Presently, throughout the world, there is rampant growth of CAM industries, and increasing number of reputed pharmaceutical companies are producing herbals and dietary supplements. Herbal products used for cardiovascular purposes include garlic, hawthorn, ginkgo, horse chestnut and arjun. These substances are often popularly believed to be ‘natural’, hence safe. But adverse reactions including deaths have been reported with some of the CAM products. There is also growing concern for significant drug interaction among commonly used herbals, dietary supplements and cardiovascular drugs. At present, CAM therapies may best be regarded as an adjunct to standard medical care. More scientific research and strict regulation by standard national and international authorities are needed to ensure their efficacy and safety in cardiovascular care.

A clinical review of large cerebello pontile angle tumors.

The study was designed as retro-prospective and the study period was 3.5 years. A total of 66 (42 prospective and 24 retrospective) consecutive patients were included in the study. The commonest tumor in CPA is the Schwannoma (76%) followed by Meningioma (13.3%) and Epidermoid (4.44%). Unusual forms are Ependymoma and Hemangiopericytoma. Amongst the troublesome clinical features headache, hearing loss, vertigo and imbalance, vomiting and tinnitus were more important besides visual failure and features of lower cranial nerve involvement. The objective of the study is to "Review the Large Cerebello Pontile Angle tumors clinically". In this study 66 large CPA tumors were included and analyzed. Analysis of variance (ANOVA) was implied for the test of significance. On the whole, n=66 Schwannoma represents 76.70% and Meningioma 15.38%. Of these there are 45 cases with histological verification. The most common presenting (average duration is 1.3 years) symptoms were Headache (94.54%) and Hearing loss of varying grade (85.45%). Vertigo or imbalance was present in 67.27% cases. Vomiting was found in 54.54% of the times and difficulties in deglutition or voice change were complained of in 29.09% cases. Tinnitus was found only in 27.27% cases and it was the complaint mostly in lower diameter tumors. By maximum diameter, there were 24 cases measuring 3-4 cm, 15 more than 4 cm and only one case <3 cm sized tumors. Volume-wise tumors with volume <10 cc were 5 cases, 10-20 cc were 10, 20-30 cc were 13, 30-40 cc were 6 and >40 cc were 6. Similarly tumor volume and posterior fossa volume ratio was as follows: <10% were 6 cases, 10-20% were 15 cases, 20-30% were 7 cases and >30% were 6 cases. Amongst the schwannomas, the consistency of the tumor has been shown to be important factor for LCN involvement. The softer variety involved LCN more often than the harder (p<0.05). The involvement of the different groups of lower cranial nerve ranged from 7% to 92%.
