RESUMO
BACKGROUND: Increased intestinal permeability (IP) has been implicated in the etiopathogenesis, disease activity and relapse of Crohn's disease (CD). Glutamine, the major fuel for the enterocytes, may improve IP. AIM: We evaluated the effect of oral glutamine on IP and intestinal morphology in patients with CD. METHODS: In a randomized controlled trial, consecutive patients with CD in remission phase with an abnormal IP were randomized to a glutamine group (GG) or active control group (ACG) and were given oral glutamine or whey protein, respectively, as 0.5 g/kg ideal body weight/day for 2 months. IP was assessed by the lactulose mannitol excretion ratio (LMR) in urine, and morphometry was performed by computerized image analysis system. RESULTS: Patients (age 34.5 ± 10.5 years; 20 males) were assigned to the GG (n = 15) or ACG (n = 15). Fourteen patients in each group completed the trial. The LMR [median (range)] in GG and ACG at 2 months was 0.029 (0.006-0.090) and 0.033 (0.009-0.077), respectively, with P = 0.6133. IP normalized in 8 (57.1%) patients in each group (P = 1.000). The villous crypt ratio (VCR) [mean (SD)] in GG and ACG at 2 months was 2.68 (1.02) and 2.49 (0.67), respectively, (P = 0.347). At the end of 2 months LMR improved significantly in GG from 0.071 (0.041-0.254) to 0.029 (0.006-0.090) (P = 0.0012) and in ACG from 0.067 (0.040-0.136) to 0.033 (0.009-0.077) (P = 0.0063). VCR improved in the GG from 2.33 (0.77) to 2.68 (1.02) (P = 0.001), and in ACG from 2.26 (0.57) to 2.49 (0.67) (P = 0.009). CONCLUSIONS: Intestinal permeability and morphology improved significantly in both glutamine and ACG.

Background: An electronic intradepartmental consultation system for anatomic pathology (AP) was conceived and developed in the laboratory information system (LIS) in 2019. Previously, all surgical pathology intradepartmental consultative activities were initiated and documented with paper forms which circulated with the pertinent microscopic slides and were eventually filed. In this study, we discuss the implementation and utilization of an electronic intradepartmental AP consultation system. Methods: Workflows and procedures were developed to organize intradepartmental surgical pathology consultations from the beginning to the end point of the consultative activities entirely using a paperless system that resided in the LIS. Results: The electronic consult system allowed electronic documentation of all steps of intradepartmental consultative activities. The system provided tracking ability for consulted cases and improved access to consult discussion for all departmental personnel, staff, and trainees. Consultation work queue was created for each pathologist and a summary of individual consultative workload was possible. Documentation of anatomic pathology quality assurance for intradepartmental consultative activity was easily assessed. Conclusions: The electronic intradepartmental consult system has allowed our department to electronically track intradepartmental consult cases, store the consultative opinion text with the case, record the pathologists involved, and document the consultation for internal quality assurance review as well as for accrediting organizations. Summarization of pathologist workload related to consultative activity was quantifiable and optimization of the consultative process was maximized for education in an academic setting.
RESUMO
Butea monosperma (Lam.) (family: Fabaceae) popularly known as 'Palas' or 'fire of forest' has been used traditionally as a hepatoprotective agent. This study evaluated the hepatoprotective and antitumorigenic properties of the aqueous extract and butanol fractions of B. monosperma flowers in animal models. Dried flowers of B. monosperma were extracted with water and fractionated further using n-butanol. The hepatoprotective activity of the aqueous extract was initially confirmed in a carbon tetrachloride-induced liver damage model of rats. Oral administration of the aqueous extract produced a strong hepatoprotective effect similar to silymarin and normalized the serum levels of ALT, AST, bilirubin and triglyceride in rats. However, it did not affect the levels of glutathione and malondialdehyde which are oxidative stress markers in liver. Intraperitoneal administration of the aqueous extract in the X15-myc oncomice not only maintained liver architecture and nuclear morphometry but also down-regulated the serum VEGF levels. Immunohistochemical staining of liver sections with anti-Ribosomal protein S27a antibody showed post-treatment abolition of this proliferation marker from the tumor tissue. The butanol fractions, however, did not show antitumorigenic activity. Thus, the aqueous extract of B. monosperma flowers is not only hepatoprotective but also antitumorigenic by preserving the nuclear morphometry of the liver.

Sellar paragangliomas are very rare lesions with only 11 previous cases described in the literature. We present a further case of sellar paraganglioma. The patient is a 17-year-old man who developed headache, visual blurring, and diplopia. MRI showed a sellar lesion. Trans-nasal trans-sphenoid biopsy showed features of paraganglioma. He was treated by Stereotactic radiotherapy. Four months after treatment he developed bone metastases which was palliated by radiation, zoledronic acid, and chemotherapy. This is the first case of sellar paraganglioma showing metastases to bone.

BACKGROUND: Comparative trials of ursodeoxycholic acid (UDCA), vitamin E and weight management programs among patients with nonalcoholic fatty liver disease (NAFLD) are lacking. AIM: To find an effective single agent or combination of agents for management of NAFLD. METHODS: In this retrospective study, consecutive patient with histologically confirmed NAFLD with raised ALT were included. The patients received either weight management (exercise and therapeutic lifestyle changes [TLC] diet with a target to reduce body weight 10% in 6 months) (group I) ; weight management + UDCA (300 mg BID) (group II); or weight management + UDCA + vitamin E (400 mg OD) (group III). Outcome measure was normalization of ALT. RESULTS: 42 patients (18, 12 and 12 in groups I, II and III, respectively) were included between 1996 and 2004. All patients in group III normalized their ALT levels, which was significantly higher than numbers in group I (8/18) and group II (5/12); (p=0.003). Post treatment ALT was significantly lower in group III (28.6 [9.3]) as compared to group I (59.3 [32.2]) and group II (49.0[31.8]); (p=0.01). Type of therapy received was the only factor predictive of ALT normalization. CONCLUSION: Combination regimen containing vitamin E appears to be effective in normalizing ALT among NAFLD patients.

We hereby report the occurrence of mediastinal liposarcoma in a 11-year-old female child. Dyspnea and wheezing of long-standing duration were the presenting complaints and a preoperative biopsy failed to yield the diagnosis. Histologic examination revealed heterogeneous areas with well-differentiated liposarcoma-like areas, areas resembling myxoid liposarcoma, and areas of dedifferentiation. Osteosarcomatous foci and whorled areas reminiscent of meningioma were identified in the dedifferentiated areas. Liposarcomas in the mediastinum are extremely rare tumors of childhood and the present case showed unusual histologic features. Complete surgical excision with clear surgical margins remains the primary modality of treatment, although chemotherapy and radiotherapy have been tried.
