Abstract
OBJECTIVE To study the vascular patterns of ovarian tumors by color Doppler imaging (CDI) and compare the findings of conventional sonographic studies and CDI with histopathologic findings for the same tumors. METHODS Fifty nonpregnant women scheduled for elective surgery for ovarian tumors were examined by sonographic scanning and CDI by the same physician. Sonographic morphology scores [SMSs] were used, and the pulsatility index (PI) and resistance index (RI) were calculated after locating vessels in and around the tumors by CDI. RESULTS It was possible to obtain CDI results in 26 of the 50 women. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were 100%, 71.43%, 73.33%, and 100%, respectively, for SMS. With CDI, the sensitivity, specificity, PPV, and NPV were 100%, 85.72%, 95%, and 100% for PI and 100%, 71.43%, 90.48%, and 100% for RI. RI sensitivity and specificity were identical to those of SMS, i.e., 100% and 71.43%, respectively, but PI specificity was better (85.72%). CONCLUSION In this study, CDI was definitely better than SMS when color flow could be obtained through the tumors. The overall efficiency in diagnosing the nature of tumors is very high if SMS and CDI are both used in patients having ovarian tumors.

Abstract
BACKGROUND People who are prescribed self-administered medications typically take less than half the prescribed doses. Efforts to assist patients with adherence to medications might improve the benefits of prescribed medications, but also might increase their adverse effects. OBJECTIVES To update a review summarizing the results of randomized controlled trials (RCTs) of interventions to help patients follow prescriptions for medications for medical problems, including mental disorders but not addictions. SEARCH STRATEGY Computerized searches were updated to September 2004 without language restriction in MEDLINE, EMBASE, CINAHL, The Cochrane Library, International Pharmaceutical Abstracts (IPA), PsycINFO and SOCIOFILE. We also reviewed bibliographies in articles on patient adherence and articles in our personal collections, and contacted authors of original and review articles on the topic. SELECTION CRITERIA Articles were selected if they reported an unconfounded RCT of an intervention to improve adherence with prescribed medications, measuring both medication adherence and treatment outcome, with at least 80% follow-up of each group studied and, for long-term treatments, at least six months follow-up for studies with positive initial findings. DATA COLLECTION AND ANALYSIS Study design features, interventions and controls, and results were extracted by one reviewer and confirmed by at least one other reviewer. We extracted adherence rates and their measures of variance for all methods of measuring adherence in each study, and all outcome rates and their measures of variance for each study group, as well as levels of statistical significance for differences between study groups, consulting authors and verifying or correcting analyses as needed. MAIN RESULTS For short-term treatments, four of nine interventions reported in eight RCTs showed an effect on both adherence and at least one clinical outcome, while one intervention reported in one RCT significantly improved patient compliance, but did not enhance the clinical outcome. For long-term treatments, 26 of 58 interventions reported in 49 RCTs were associated with improvements in adherence, but only 18 interventions led to improvement in at least one treatment outcome. Almost all of the interventions that were effective for long-term care were complex, including combinations of more convenient care, information, reminders, self-monitoring, reinforcement, counseling, family therapy, psychological therapy, crisis intervention, manual telephone follow-up, and supportive care. Even the most effective interventions did not lead to large improvements in adherence and treatment outcomes. Six studies showed that telling patients about adverse effects of treatment did not affect their adherence. AUTHORS' CONCLUSIONS Improving short-term adherence is relatively successful with a variety of simple interventions. Current methods of improving adherence for chronic health problems are mostly complex and not very effective, so that the full benefits of treatment cannot be realized. High priority should be given to fundamental and applied research concerning innovations to assist patients to follow medication prescriptions for long-term medical disorders.

Abstract
Microbicides are a new category of compounds being developed as a prophylactic approach for the prevention of transmission of sexually transmitted diseases (STDs), including the human immunodeficiency virus (HIV). These are primarily being developed as women-controlled methods, with the target of designing new compounds or formulations that can be used without the knowledge of a male partner. Microbicide screening can be initially based on their hyaluronidase-inhibiting (HI) activity, as this enzyme plays a major role in the sperm and microbe penetration into the substrate. Derivatives of hesperidin, a citrus flavonoid glycoside, have been reported in the literature for their HI effects. Hesperidin was thereby sulphonated under strictly controlled conditions and the active fraction isolated and characterized, based on its HI activity. This derivative was screened for antimicrobial and enzyme-inhibitory activities, specifically for the reproductive tract. Sulphonated hesperidin (SH) was found to completely inhibit the sperm enzymes hyaluronidase, giving an indication toward its contraceptive effects. It was also been found to inhibit various sexually transmitted pathogens, including Chlamydia trachomatis, Neisseria gonorrhoea, HIV, and Herpes Simplex virus type 2 (HSV-2). Its safety assessment was based on its noninterference in sperm motility and its penetration through the cervical mucus, and no effect on the growth of lactobacilli, the normal vaginal flora. It was also found to be nontoxic to the HIV substrate cells (MT2 cells). The study concludes that sulphonated hesperidin can be developed as a potential microbicide for a dual prophylaxis of contraception and transmission of STDs and AIDS.

Abstract
BACKGROUND Many unlinked total elbow replacement designs with radically differing articular geometries exist, suggesting that there is no consensus regarding an optimal design. A feature inherent to the articular design is the intrinsic constraint afforded to the joint by the implant. Our aim was to compare the intrinsic constraints of unlinked implants with that of the normal ulnotrochlear joint. METHODS We tested twelve cadaveric ulnotrochlear joints with a custom-made multiple-axis materials testing machine. With compressive loads ranging from 10 to 100 N, the joints were moved in either valgus or varus directions at 90 degrees of flexion. The ulnotrochlear components from a single example of five medium-sized unlinked elbow replacements (Ewald, Kudo, Pritchard ERS, Sorbie-Questor, and Souter-Strathclyde) were also tested. The recorded measurements included the torques and forces, angular displacement, and axial displacement of the humerus relative to the ulna. RESULTS In general, the peak torque and the constraint ratio significantly increased with increasing compressive load for the implants as well as for the normal elbow. In valgus displacement, the Souter-Strathclyde implant had the highest and the Sorbie-Questor had the smallest peak torque and the Souter-Strathclyde had the highest and the Ewald had the smallest constraint ratio. In varus displacement, the Kudo had the highest and the Ewald had the smallest peak torque and constraint ratio. CONCLUSIONS The constraint ratio is a characteristic that is useful for describing elbow joint behavior and for comparing the behavior of implants with that of the human elbow. Of the unlinked implants tested, the Souter-Strathclyde and Kudo prostheses most closely approximated the behavior of the human elbow joint. Implants that resemble the human elbow in appearance do not replicate normal behavior consistently, whereas other implants that do not resemble the human elbow closely do not deviate markedly from human behavior. Thus, much basic information about elbow form and function is needed to improve the performance of total elbow prostheses.

Abstract
A case of ossifying spinal lipoma is reported. The patient presented with a large swelling over the lumbar region with a dermal sinus in the centre. Imaging revealed an intradural lipoma connected with a large subcutaneous lipoma in which there was a prominent island of bone. The lipoma was excised and there were no postoperative neurological deficits. To the best of our knowledge, this is the first report of a spinal ossifying lipoma associated with a dermal sinus.

Abstract
We have mapped the quantitative trait loci (QTLs) conferring resistance to sorghum downy mildew (Peronosclerospora sorghi; SDM) and Rajasthan downy mildew (P. heteropogoni; RDM), two species of DM prevalent throughout India. QTL mapping was carried out on a backcross population of 151 individuals derived from a cross between CM139 (susceptible parent) and NAI116 (highly resistant to both SDM and RDM). Heritability estimates were 0.74 for SDM and 0.67 for RDM. Composite interval mapping combined with a linkage map constructed with 80 simple sequence repeat (SSR) markers resulted in the identification of three QTLs (one each on chromosomes 2, 3 and 6) for SDM resistance and two QTLs (one each on chromosomes 3 and 6) for RDM resistance, all of which were contributed by NAI116. The significance of the major QTL on chromosome 6 (bin 6.05) that confers resistance to diverse DMs in tropical Asia, including SDM and RDM in India, was also verified. The results confirmed that some common QTLs contribute to both SDM and RDM resistance, while additional loci might specifically govern resistance to SDM. The QTL information generated in this study provide information that will aid in undertaking an integrated breeding strategy for the transfer of resistance to SDM and RDM in maize lines using marker-assisted selection.

Abstract
OBJECTIVE India has more than 20,000 registered pharmaceutical manufacturers. Consequently, there is a flood of brand names to choose from. We conducted this study to analyse and sort out the multitudinous brand names thronging the Indian market, and identified those that could create a possible confusion. MATERIALS AND METHODS Recent issues of drug formularies like Indian Drug Review, Drug Index, and Monthly Index of Medical Specialities-India were checked and all the brand names given were included. Some other brand names that are available with the pharmacists but are not included in these indexes were also included in the study for analysis. OBSERVATIONS Potentially confusing brand names were sorted out and categorised according to the severity of damage they can cause if misinterpreted by the pharmacist or the patient. Subgroups were made according to the brand name, the generic name, and the manufacturers of the drug. CONCLUSION Several brand names are strikingly identical, similar looking (orthographic), or similar sounding (phonological). Preventing this possible confusion is not the work of any one person involved. We describe the role of prescribing doctors, dispensing pharmacists, consumer patients, and the manufacturing companies to prevent "wrong prescribing" due to similarities in brand names.

Abstract
Malignant peripheral nerve sheath tumors (MPNSTs) are rare neoplasms, usually arising from somatic soft tissues or peripheral nerves. Primary MPNST of the scalp is extremely rare, with only a single case reported so far. Here, we describe an unusual case of scalp MPNST in a 50-year-old male. The tumor was associated with bony projection, intracranial extension and underlying bone destruction. The tumor was treated with complete surgical excision followed by adjuvant radiotherapy. Histologically, the tumor showed malignant spindle cells with focal S-100 positivity on immunohistochemistry and a diagnosis of MPNST was made. This case is being reported for its rarity and presence of associated bony projection, which to the best of our knowledge, has not been described before in soft tissue sarcomas.

Abstract
Congenital generalized lipodystrophy (CGL) is an autosomal recessive disorder characterized by extreme lack of body fat and severe insulin resistance since birth. Recently, mutations have been reported in 1-acylglycerol-3-phosphate-O-acyltransferase 2 (AGPAT2) and Berardinelli-Seip congenital lipodystrophy 2 (BSCL2 or Seipin) genes in affected subjects from pedigrees linked to chromosomes 9q34 and 11q13, respectively. The AGPAT2 catalyses the acylation of the lysophosphatidic acid at the sn-2 position to form phosphatidic acid, a key intermediate in the biosynthesis of triacylglycerol and glycerophospholipids. High expression of AGPAT2 mRNA in adipose tissue compared to other isoforms suggests that the mutations might affect the adipose tissue the most. The function of BSCL2 remains unknown. Several CGL pedigrees reveal no mutation in either of the above genes and are not linked to these loci, suggesting additional genetic loci for CGL. Thus, several distinct mechanisms can lead to extreme lack of adipose tissue in humans and cause CGL.

Abstract
Cerebrotendinous xanthomatosis (CTX) is exceptionally rare in the Indian population. We present and discuss the clinical, radiological and histopathologic findings in 2 siblings with CTX. Both the patients had juvenile cataract, mental retardation and marked cerebellar ataxia. The Achilles tendon swelling was present in only 1 patient (Case 2). MR imaging showed typical bilateral and symmetrical involvement of the dentate nuclei, inferior olives, brainstem and cerebellar hemispheric white matter. Although the diagnosis of CTX was made in the 3rd decade in both our cases, early diagnosis is possible if neuroimaging is done in the early course of the disease.

Abstract
We report two cases of lumbar spinal dermoid cysts with asymptomatic rupture and migration of free fat droplets into the central canal. No fatty droplets were seen within the lumbar subarachnoid space. The presence of fat droplets within the central canal is unusual because the central canal is rudimentary in adults. We suggest that hydromyelia secondary to tumour and specific tumour morphology might facilitate the selective rupture of dermoids into the central canal. We recommend a follow up of these patients to detect any possible intracranial migration of fat droplets and resultant complications.
