Abstract
BACKGROUND Cervical epidural anaesthesia (CEA) using local anesthetics (LA) is a well established technique for the surgeries in the neck, chest and upper arms. Recently ropivacaine is introduced with better safety profile. OBJECTIVES The aim was to observe the safety of Cervical epidural anaesthesia as an anaesthetic technique and to compare the efficacy of epidural 0.25% bupivacaine with 0.375% ropivacaine for radical mastectomies. METHODS A double blind study was conducted on 40 ASA grade I / II females who received CEA with 10 ml of 0.25% of bupivacaine +25μg of fentanyl in group B (n=20) and 10 ml of 0.375% of ropivacaine +25μg of fentanyl in group R (n=20) epidurally. Assessment of the block, vital monitoring and complications noted. RESULTS No significant differences observed in the onset of sensory block (5.05 min and 5.4 min in group B and R respectively, P>0.05).The mean motor blockade score, time to achieve complete blockade and time to grade I motor recovery was significantly longer in group B (2.3, 22.5 and 79.5 minutes respectively) as compared to group R (1.5, 18.3 and 66.3 minutes respectively, P<0.05). Respiratory distress developed in two patients of group B that required general anaesthesia (GA) with intubation. CONCLUSION Use of 0.37% ropivacaine is safer than 0.25% bupivacaine for CEA for radical mastectomy. It provides good surgical anaesthesia with lesser degree of motor blockade and the respiratory effects.

Abstract
Sequestrated meningocoele is an uncommon developmental anomaly in which meningothelial elements are found in the skin or subcutaneous tissue without underlying bony defect. By contrast, naevus sebaceous of Jadassohn (NSJ) is a circumscribed hamartomatous lesion occurring in about 0.3% of newborns. We report a child with a histologically confirmed sequestrated meningocoele within an NSJ on his scalp vertex. Such an occurrence has not been reported previously.

Abstract
Kernel size and morphology influence the market value and milling yield of bread wheat (Triticum aestivum L.). The objective of this study was to identify quantitative trait loci (QTLs) controlling kernel traits in hexaploid wheat. We recorded 1000-kernel weight, kernel length, and kernel width for 185 recombinant inbred lines from the cross Rye Selection 111 × Chinese Spring grown in 2 agro-climatic regions in India for many years. Composite interval mapping (CIM) was employed for QTL detection using a linkage map with 169 simple sequence repeat (SSR) markers. For 1000-kernel weight, 10 QTLs were identified on wheat chromosomes 1A, 1D, 2B, 2D, 4B, 5B, and 6B, whereas 6 QTLs for kernel length were detected on 1A, 2B, 2D, 5A, 5B and 5D. Chromosomes 1D, 2B, 2D, 4B, 5B and 5D had 9 QTLs for kernel width. Chromosomal regions with QTLs detected consistently for multiple year-location combinations were identified for each trait. Pleiotropic QTLs were found on chromosomes 2B, 2D, 4B, and 5B. The identified genomic regions controlling wheat kernel size and shape can be targeted during further studies for their genetic dissection.

Abstract
Classification schemes proposed for vascular lesions are the subjects of significant controversy. Cutaneous epithelioid angiomatous nodule (CEAN) was described in 2004, but there is no agreement as to whether this is a distinct entity or a type of either epithelioid hemangioma or angiolymphoid hyperplasia with eosinophilia. We present a typical case of CEAN and discuss nine other cases from our institution. We then provide two opposing viewpoints concerning its classification.

Abstract
The dosage of (131)I for the treatment of metastatic well-differentiated thyroid cancer is typically selected empirically. Benua and Leeper implemented a method to estimate the maximum dosages of (131)I that could be administered to a patient so as not to exceed a maximum tolerated radiation absorbed dose (MTD), which was defined as 200 rads (cGy) to the blood. The objective of this study was to determine the frequency of (131)I treatments in which the patient (1) would have exceeded the MTD (i.e., overtreatment) or (2) would have been able to receive higher dosages of (131)I thereby delivering a potentially higher radiation absorbed dose to their metastases (i.e., undertreatment) had the patient been administered various assumed empiric dosages of (131)I. The dosimetrically-determined maximum tolerated radioactivities (MTA) to deliver 200 rads to the blood (MTD) were tabulated at our facility. Data were then grouped to determine the percentage of patients who would have received less than or more than the MTD for various assumed empiric dosages of (131)I. A total of 127 dosimetries were performed. For assumed empiric dosages of (131)I (100 mCi, 150 mCi, 200 mCi, 250 mCi, and 300 mCi), the percentage of treatments for which patients would have exceeded the MTD were less than 1%, 5%, 11%, 17%, and 22%, respectively, and could have received a higher dosage of (131)I were more than 99%, 95%, 89%, 83%, and 78%, respectively. A significant number of patients receiving various empiric dosages of (131)I may exceed 200 rads (cGy) to the blood (potential overtreating). Likewise, the majority of patients may be able to receive much higher dosages of (131)I relative to empiric dosages thereby delivering potentially higher radiation absorbed doses to the metastases without exceeding 200 rads (cGy) to the blood (potential undertreating).

Abstract
UNLABELLED Brown fat uptake of 2-deoxy-2-[F-18]fluoro-D: -glucose (FDG) on a positron emission tomography (PET) scan limits the ability to assess for cancer. Drugs such as benzodiazepine, propranolol, and reserpine have been proposed to reduce this uptake, but the studies have been either small clinical or preclinical trials. As an alternative, we evaluated the effect of controlling the patient's environmental temperature on brown fat uptake of FDG. METHOD From January 1, 2002 to November 30, 2004, patients were identified who had (1) a pattern of FDG uptake in the neck/paravertebral areas suggestive of brown fat, (2) a repeat FDG-PET scan after control of the patient's environmental temperature, and (3) no evidence of cancer in the neck/paravertebral areas by other diagnostic methods. For the follow-up PET scan, all patients wore warm clothing and avoided exposure to cold air during their transit to our facility. After arrival, patients were kept in a separate temperature-controlled room (at least 75 degrees F) for 15 minutes to two hours before FDG injection as well as during the uptake phase. Four physicians blindly and retrospectively assessed the FDG uptake in the neck and paravertebral regions on all initial and temperature-controlled PET scans by visually grading the radioactivity on a semiquantitative scale (0 = background, 1+ = background but <liver, 2+ = equal to liver, 3+ >liver). The changes in maximal SUVs were determined in the left and right neck region. Data were evaluated using a two-tail t-test. RESULTS Ten patients met the above criteria. The median age was 32 years with a range of 11-58 years. In comparing the semiquantitative uptake and the SUVs of FDG in the neck and paravertebral areas on the initial PET scan to the temperature-controlled PET scan, the mean decrease and the standard deviation of the decrease demonstrated a statistically significant decrease in with P values range from <0.02 to <0.001. CONCLUSION Controlling the patient's environmental temperature prior to the dosing and during the uptake phase can significantly reduce FDG uptake in brown fat in the neck and paravertebral areas. Further studies are warranted to determine the most effective protocol to control the patient's environmental temperature in order to minimize brown fat uptake.

Abstract
This case report describes a patient with Sjögren syndrome (SS) whose sole presenting feature was bilateral and painful submandibular gland enlargement. Extensive workup for alternate etiologies was negative and while serologies specific for SS were unremarkable, the diagnosis was eventually suggested by excisional biopsy. This case highlights the difficulty in making an early diagnosis of SS and demonstrates the important role of excisional biopsy in that diagnosis.

Abstract
AIMS To assess if the rising incidence of hepatocellular carcinoma in the United States can be accounted for by immigration and an ageing population, or is a true increase among the USA-born residents. METHODS Design--A retrospective chart review. Setting--Urban, multiethnic hospital and specialty clinics in a large indigent health system in Houston, Texas. Subjects--Approximately 23,000 admissions and 143,000 out-patient clinic visits each year from 1992 through 2001 were assessed. A total of 494 patient records were selected and reviewed because of suspicion of hepatocellular carcinoma. Analysis- Hepatocellular carcinoma was confirmed by histopathology, alpha-fetoprotein level >400 ng/mL, and suggestive imaging studies. The age-adjusted incidence was determined and causative factors were identified. RESULTS About 111 cases of confirmed hepatocellular carcinoma were found. The age-adjusted incidence rose from 3.44 per 100,000 hospital admissions during 1992-1996 (95% confidence interval: 2.86-4.02) to 5.19 during 1997-2001 (95% confidence interval: 4.41-5.97). The proportion of patients of non-USA place of birth decreased between 1992-1996 and 1997-2001 (46-24%, respectively, P = 0.03). Fifty-two per cent and 68% were hepatitis C virus-positive respectively; 37% and 34% were hepatitis B surface antigen-positive respectively; 46% and 59% had a history of alcohol abuse; and 22% and 11% had no identifiable risk factors. CONCLUSIONS The incidence of hepatocellular carcinoma within the greater Houston area has increased during the past decade, rising by 51% from 1992-1996 to 1997-2001. This increase is not from immigration or population ageing but represents a true rise among the native born population. Hepatitis C and alcoholic cirrhosis are associated with a majority of cases, particularly in the latter half of the decade.

Abstract
OBJECTIVE To screen a collection of isolates of Haemophilus ducreyi for expression of the cytolethal distending toxin (CDT). METHODS 45 clinical isolates of H ducreyi were screened for cytotoxic activity by examining the effect of culture supernatants on Hela cells. Expression was confirmed using immunoblotting with CDT specific monoclonal antibodies and the presence of the cdt genes determined by amplification of the cdt genes in a multiplex polymerase chain assay. RESULTS Of the 45 clinical isolates, six isolates from differing geographical origins did not demonstrate cytotoxic activity. Expression of CDT was also not detected in these six isolates using immunoblotting and the genes cdtA, cdtB, and cdtC were not amplified using PCR. The remaining isolates demonstrated cytotoxic activity, expressed the CDT proteins, and the presence of the cdt genes was confirmed. CONCLUSIONS CDT is considered a virulence factor of H ducreyi but was found to be absent in 13% of isolates from different geographical origins.
