The Presence of Portal Vein Thrombosis Alters the Classic Enhancement Associated with Diagnosis of Hepatocellular Carcinoma

Digestive Diseases and Sciences - To determine whether the presence of portal vein thrombosis (PVT) where venous flow within the liver may be altered may delay the diagnosis of HCC and be...     

Child sexual abuse--children and families referred to a treatment project and the effects of intervention.

The characteristics of a series of 274 families who were referred to a sexual abuse treatment programme were analysed. Information was obtained on 411 abused children and 362 non-abused children. Different forms of sexual abuse were noted, with 77% of girls and 23% of boys affected. Boys tended to be abused at a younger age, more severely, and for longer periods than girls. There was a predominance of lower social class groups among the parents, and a wide variety of family structures, with reasonable stability over time. Ninety six per cent of perpetrators were men, and biological and step-parents predominated. Contributing factors in both the family history and the current perpetrators and their wives included sexual abuse, violence, chaotic families, marital problems, sexual difficulties, alcoholism, and subnormality. Follow up of 120 families, 180 victims, and 226 siblings showed that prosecution occurred in 60% of cases, with a high percentage of perpetrators being imprisoned. Treatment was offered to 87% of families, but because the treatment programme was in the early stages of development a variable number of children and parents were offered family treatment or treatment in groups for parents and children separately. There was an improvement in the victim's circumstances in 61% of cases, and a noticeable reduction in "sexualised" and general emotional difficulties among victims, but there was reabuse rate of 16%. Protection of children was achieved through changes of family attitude and changes in family structure including divorce and separation: 14% of victims were rehabilitated to both parents, 33% to mothers only, and 26% to new families or other residences. Consensus in the family that abuse had occurred was seen as an important factor in determining which children could be rehabilitated with both their parents, with their mothers only, or with new families; which families could be offered or accepted treatment; and whether positive changes in the family occurred.     

Safety, efficacy, and lipid profile of doxazosin at a VA medical center

The Veterans Administration Lakeside Medical Center (VALMC) is a 500-bed hospital located in downtown Chicago providing a broad scope of inpatient and outpatient medical services for more than 12,000 veterans. The VALMC Pharmacy and Therapeutics Committee requested a study to evaluate doxazosin mesylate (Cardura) to determine if this agent would be an acceptable alternative to other formulary agents. It appears that doxazosin provides several therapeutic advantages, including once-daily dosing, when compared with other more costly antihypertensive agents.     

Prevalence,pattern, sensitivity and resistance to antibiotics of different bacteria isolated from port site infection in low risk patients after elective laparoscopic cholecystectomy for symptomatic cholelithiasis at tertiary care hospital of Kashmir

The aim of this study was to determine specific pattern of port site microbial colonisation, sensitivity and resistance to different antibiotics of bacteria isolated from port site infection (PSI) in low risk patients after elective laparoscopic cholecystectomy in surgical wards at tertiary care hospital of Kashmir. This is a prospective study. The study included 675 consecutive patients of postoperative PSI after elective laparoscopic cholecystectomy for symptomatic cholelithiasis over a period of 12 months. Culture swabs were taken from port sites with signs of PSI and transported to the microbiology laboratory. The positive swab cultures were subjected to antibiotic susceptibility test. The data obtained was analysed by using appropriate statistical analytical tests. The incidence of PSI after elective laparoscopic cholecystectomy is 6·7%. The commonest organism responsible for PSI is pseudomonas, 19 (42·2%) cases. Most of the strains of organisms isolated were resistant to commonly used antibiotics in the hospital,pseudomonas was found 100% resistant to the combination of ampicillin + sulbactum and ceftriaxone and it was sensitive to imipenem, amikacin and vancomycin in 89·47,57 and 52·63% of cases respectively. Our study will be helpful in choosing effective empirical prophylactic antibiotic therapy in cases of elective laparoscopiccholecystectomy and will have a great impact on morbidity and mortality in them because of PSI.     

Multi-constituent synergism is responsible for anti-inflammatory effect of Azadirachta indica leaf extract

Context: Azadirachta indica A. Juss. (Meliaceaes) leaves have been used traditionally to treat swelling and rheumatism in Indian cultures.

Objective: To fractionate A. indica leaf extracts using bioactivity guided manner for identification of the active anti-inflammatory principles.

Materials and methods: Polarity-gradient sequential extracts (petroleum ether, chloroform, methanol, and water) of A. indica leaves were screened for their anti-inflammatory potential using the carrageenan-induced rat paw edema model (1?g/kg). The chloroform extract was sequentially fractionated to obtain n-hexane (F-1), n-hexane-chloroform (F-2), and chloroform (F-3) fractions and their inhibitory effect on rat paw edema was evaluated (500?mg/kg). Inhibitory effect of F-2 on granuloma formation, plasma interleukin (IL-1), and tumor necrosis factor (TNF-α) was assessed at the doses of 100, 200, and 400?mg/kg using the cotton pellet assay in rats. Three sub-fractions (SF-1, SF-2, and SF-3) were obtained upon chromatography of F-2, and their inhibitory effect on cyclooxygenase was assessed at 200?µg/mL concentration. The sub-fractions were subjected to gas chromatography–mass spectrometry (GC-MS).

Results: All the extracts showed significant anti-inflammatory effect; however, chloroform extract was the most effective against paw edema (53.25% inhibition). The three fractions of chloroform extract showed significant effect, while F-2 being the most potent (51.02%). F-2 demonstrated dose-dependent inhibition of granuloma and cytokines. Interestingly, all the sub-fractions of F-2 inhibited COX-1 and COX-2 with almost equal potential. GC-MS revealed that chemically the sub-fractions were totally different from each other.

Discussion and conclusion: Anti-inflammatory effect of A. indica is a result of cumulative and synergistic effects of diversified constituents with varying polarities that collectively exert the effect via suppression of cyclo-oxygenases and cytokines (IL-1 and TNF-α).
