Abstract
PURPOSE To investigate inflammation and cell adhesion molecules in the vagina after ovarian ischemia-reperfusion (IR) injury. METHODS 20 Wistar albino female rats were divided into two groups: control, and IR groups. In IR group, blood flow was restricted for 2 hours for ovarian ischemia. Then, tissues were re-blood 2 hours for reperfusion. Vagina tissues were excised and processed for histopathological analysis. Histopathological and biochemical follow-ups were performed. RESULTS Both malondialdehyde and myeloperoxidase values were increased in IR group compared to control group. Glutathione content was decreased in IR group compared to control group. Epithelial degeneration, inflammation, dilatation, and nuclear factor-κB (NF-κB) expression were increased in IR group compared to control group. E-cadherin expression was significantly decreased in IR group. In the IR group, E-cadherin showed a positive reaction in adenomas, gland-like cryptic structures, cellular junctions with clustered inflammatory cells. In the IR group, NF-κB expression was increased in basement membrane, inflammatory cells, in blood vessels. CONCLUSIONS Ovarian ischemia caused degeneration of epithelial cells in the vaginal region and disruptions in the cell junction complex, which leads to activation of E-cadherin and NF-κB signaling pathway and alterations in reproductive and embryonal development in the vaginal region.

Abstract
PURPOSE We aimed to reveal the effects of rosmarinic acid (RA), which has come to the forefront with its antitumor and antioxidant properties in many studies recently in the ovarian adenocarcinoma cell line, on the epidermal growth factor receptor (EFGR) signaling pathway in the presence of doxorubicin (DOX). METHODS Ovarian adenocarcinoma cell line (OVCAR3) and human skin keratinocyte cell line human skin keratinocyte cell line (HaCaT) were used as control. (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) test was applied to determine the effect of RA and DOX on the proliferation of OVCAR3 and HaCaT cells. Bcl2 expression and epidermal growth factor receptor (EGFR) and western blot analysis were performed to determine the expression levels of the markers. RESULTS It was determined that RA (IC50 = 437.6 μM) and DOX (IC50 = 0.08 μM) have the ability to inhibit the proliferation of OVCAR3 cells and induce apoptosis in a 72-hour time and dose-dependent manner. Western blot showed that the expression level of Bcl-2 and EGFR in OVCAR3 cells was down-regulated by RA and DOX. CONCLUSIONS Apoptosis in OVCAR3 cells can potentially be induced by RA via the EGFR pathway, and RA may be a potent agent for cancer therapy.

Abstract
Abstract Drought is one of the most damaging abiotic stress that hinder plant growth and development. The present study aimed to determine the effects of various Ca/Mg quotients under polyethylene glycol (PEG)–induced osmotic stress on growth, uptake and translocation of Ca and Mg in Avena sativa (L). Plants were grown in nutrient solution supplemented with three different Ca/Mg molar quotients (0.18, 2, and 4). After 30 days plants were exposed to two different PEG (Polyethylene glycol) concentrations (0.6 MPa & 0.2 MPa) for 8 days, and solutions were renewed after 4 days. A solution containing Ca and Mg nutrients has mitigated the negative impact caused via osmotic stress on relative growth rate (RGR), absolute growth rate (AGR), crop growth rate (CGR), leaf area ratio (LAR), Leaf index ratio (LAI), root-shoot ratio (RSR), water use efficiency (WUE) and net assimilation rate (NAR). In addition, it adversely affected germination parameters, including final emergence percentage (FEP), mean germination time (MGT), Timson germination Index (TGI), germination rate index (GRI) and percent field capacity (%FC), of oat (Avena sativa L.). Mg and Ca in shoot and root and Ca translocation factor decreased with increasing Ca in solution, while Mg translocation factor increased with increasing Ca in nutrient solution. In this work, the combined effects of various Ca/Mg quotients and osmotic stress produced by polyethylene glycol (PEG) in different concentrations (0.6 MPa, 0.2 MPa) on the growth and element uptake of Avena sativa L. are examined. As a result, the Ca/Mg Quotient may naturally combat the moderate drought stress experienced by field crops.

Abstract
Nosocomial infection is a major challenge for the appropriate management of burns. The present study aimed to investigate incidence, risk factors, and causative organisms of nosocomial infection in burn patients of Khulna, Bangladesh. This cross-sectional study was conducted among patients admitted to the Burn and Plastic Surgery Department of Khulna Medical College Hospital (KMCH) from January to December 2020. Relevant data were collected from the patients' hospital records. Samples of wound swabs and blood were collected and cultured in the microbiology laboratory of KMCH. Logistic regression models were used to determine risk factors for infective complications in burn patients. All statistical analyses were carried out using SPSS version 26.0. A total of 100 burn patients were included. Mean age was 29.2 years with a male-female ratio of 1.3:1. Flame burns were most prevalent among the patients (41%), followed by scald (23%) and electric burns (15%). Almost 40% patients had full thickness burn. The incidence of nosocomial infection was 42% (wound infection 33% and septicemia 9%). Total body surface area of burn >40% (OR 7.56, 95% CI 2.89-19.81), full thickness burn (OR 34.40, 95% CI 3.25-97.14) and prolonged hospital stay (aOR 1.31, 95% CI 1.15-1.51) were significant risk factors for nosocomial infection. Staphylococcus aureus was the most commonly isolated organism (45%), followed by Streptococcus (24%), Pseudomonas aeruginosa (19%) and Escherichia coli (12%). As the epidemiology of nosocomial infection is not the same in different health facilities, a facility-based comprehensive burn management protocol considering the local epidemiology and causative organisms of burn wound infection is crucial for the prevention and management of nosocomial infections in burn patients.

Abstract
BACKGROUND Mucosal melanoma (MM) is a rare melanoma subtype with distinct biology and poor prognosis. Data on the efficacy of immune checkpoint inhibitors (ICIs) is limited. We determined the efficacy of ICIs in MM, analysed by primary site and ethnicity/race. PATIENTS AND METHODS Retrospective cohort study from 25 cancer centres in Australia, Europe, USA and Asia. Patients with histologically confirmed MM were treated with anti-PD1+/-ipilimumab. Primary endpoints were response rate (RR), progression-free survival (PFS), overall survival (OS) by primary site (naso-oral, urogenital, anorectal, other), ethnicity/race (Caucasian, Asian, Other) and treatment. Univariate and multivariate Cox proportional hazard model analyses were conducted. RESULTS In total, 545 patients were included: 331 (63%) Caucasian, 176 (33%) Asian and 20 (4%) Other. Primary sites included 113 (21%) anorectal, 178 (32%) urogenital, 206 (38%) naso-oral and 45 (8%) other. 348 (64%) received anti-PD1 and 197 (36%) anti-PD1/ipilimumab. RR, PFS and OS did not differ by primary site, ethnicity/race or treatment. RR for naso-oral was numerically higher for anti-PD1/ipilimumab (40%, 95% CI 29-54%) compared with anti-PD1 (29%, 95% CI 21-37%). 35% of patients that initially responded progressed. Median duration of response (mDOR) was 26 months (95% CI 18-NR [Not Reached]). Factors associated with short PFS were ECOG PS ≥3 (p<0.01), LDH >ULN (p=0.01), lung metastases (p<0.01) and ≥1 previous treatments (p<0.01). Factors associated with short OS were ECOG PS ≥1 (p<0.01), LDH >ULN (p=0.03), lung metastases (p<0.01) and ≥1 previous treatments (p<0.01). CONCLUSIONS MM has poor prognosis. Treatment efficacy of anti-PD1+/-ipilimumab was similar and did not differ by ethnicity/race. Naso-oral primaries had numerically higher response to anti-PD1/ipilimumab, without difference in survival. The addition of ipilimumab did not show greater benefit over anti-PD1 for other primary sites. In responders, mDOR was short and acquired resistance was common. Other factors, including site and number of metastases were associated with survival.

Abstract
An observational longitudinal study was conducted in the Department of Neonatology and Child Developmental Center, Mymensingh Medical College Hospital (MMCH), Bangladesh during the period of September 2016 to February 2018 to find out the neuro-developmental outcome of high risk neonates at the age of 6 months. Five hundred seventy six (576) high risk neonate who were admitted in the neonatology department in Mymensingh Medical College Hospital were selected as study population by Purposive sampling technique. After admission written informed consent from parents or guardians obtained and Data was collected in a pre-designed case record form. At 6th months of age total 400 baby were came to Child Development Centre and their motor, cognition and behavior development were assessed by Bayley Scale of Infant Development and severity of cognitive, motor and behavior impairment were graded. All data were compiled, tabulated and then analyzed by computer software SPSS version 20.00. Mean age was 7.2±3.3 days. Among studied newborns 18.1% were preterm and 81.9% were term. Most of the newborn were male (63.0%). Developmental delay was found in 81.5% and neuro-developmental outcome was found normal in only 18.5% newborns. Significant delayed motor performance was found in 52% newborns where 17% had mild delay. Significantly delayed mental performance was found in 57.0% and 28.52% had mildly delayed mental performance. Non-optimal behavior was found in 57.0% newborns and14% had questionable behavior. Very low birth weight, preterm very low birth weight, home delivery, perinatal asphyxia and neonatal seizure were found to have significant relation with developmental delay. Most of the high risk neonates develop developmental delay.

Abstract
BACKGROUND Anti-programmed cell death protein 1 (PD-1) antibodies (PD1) prolong recurrence-free survival in high-risk resected melanoma; however, approximately 25%-30% of patients recur within 1 year. This study describes the pattern of recurrence, management and outcomes of patients who recur with adjuvant PD1 therapy. PATIENTS AND METHODS Consecutive patients from 16 centres who recurred having received adjuvant PD1 therapy for resected stage III/IV melanoma were studied. Recurrence characteristics, management and outcomes were examined; patients with mucosal melanoma were analysed separately. RESULTS Melanoma recurrence occurred in 147 (17%) of ∼850 patients treated with adjuvant PD1. In those with cutaneous melanoma (n = 136), median time to recurrence was 4.6 months (range 0.3-35.7); 104 (76%) recurred during (ON) adjuvant PD1 after a median 3.2 months and 32 (24%) following (OFF) treatment cessation after a median 12.5 months, including in 21 (15%) who ceased early for toxicity. Fifty-nine (43%) recurred with locoregional disease only and 77 (57%) with distant disease. Of those who recurred locally, 22/59 (37%) subsequently recurred distantly. Eighty-nine (65%) patients received systemic therapy after recurrence. Of those who recurred ON adjuvant PD1, none (0/6) responded to PD1 alone; 8/33 assessable patients (24%) responded to ipilimumab (alone or in combination with PD1) and 18/23 (78%) responded to BRAF/MEK inhibitors. Of those who recurred OFF adjuvant PD1, two out of five (40%) responded to PD1 monotherapy, two out of five (40%) responded to ipilimumab-based therapy and 9/10 (90%) responded to BRAF/MEK inhibitors. CONCLUSIONS Most patients who recur early despite adjuvant PD1 develop distant metastases. In those who recur ON adjuvant PD1, there is minimal activity of further PD1 monotherapy, but ipilimumab (alone or in combination with PD1) and BRAF/MEK inhibitors have clinical utility. Retreatment with PD1 may have activity in select patients who recur OFF PD1.

Abstract
Global population is ageing and Bangladesh has one of the fastest growing ageing populations in this region. Growth in the elderly population relative to other age groups challenges existing health services, family relationships and social security. Combined with this, depression has become a major mental health problem for elderly people especially for urban elderly for nuclear family norm in urban areas. The study was descriptive type of cross-sectional in nature and was conducted in Rangpur Medical College Hospital, Rangpur & Prime Medical College Hospital, Rangpur, Bangladesh. The objective of this study was to assess the lifestyle and level of depression in urban elderly. Depression was measured by questionnaire of geriatric depression scale among 254 respondents. 87.8% of the respondents were age between 60-70 years. Majorities (63%) of the respondents were male, 54% of the respondents lived in nuclear type family and the rest (46%) in joint type of family. Among respondents near half (47.2%) of the respondents found Mild depressive, around one third (32.7%) were severe depressive, and the rest (20.1%) were normal. There was significant association between occupational status of the respondents and depression (x² = 45.600, df=14, p=0.000). Farmers unemployed found severely depressive (52.1%) followed by day-labourer (50%) and businessmen (37.5%). There was significant association between financial self dependency and depression of the respondents (x²= 34.072, df=4, p=0.000). Severe depression (43.8%) was found among those who were not financially self dependent. There was also significant association between monthly income and depression of the respondents (x²= 67.327, df=8, p=0.000). The study also found that lower income group (<Tk 10000) suffer more from severe depression (42.1% vs. 16.67%) than that of higher income group (Tk 50000-99999). Another significant association found between respondents living with family and depression (x²=16.025, df=2, P=0.000). Respondents those not living with family were suffering more from severe depression (55.55%). Association between social activity and depression (x²=31.724, df=4, p=0.000) revealed that those not involved in social activities were in severe depression (40.55%). The study concluded that lifestyle factors and socio-demographic conditions directly influence the state of depression. Those who lead a healthy social life with friends and family, with a stable income source are less prone to severe depression and vice versa. The study recommended the formulation of strategies for the well being of urban elderly that should include social awareness about positive lifestyle changes, social mobilization, health assurance, and response from the government so that depression and its associated serious diseases can be prevented.

Abstract
Disorders of sodium and water metabolism are frequently encountered in hospitalized patients. Hyponatremia in critically ill patients can cause significant morbidity and mortality. Inappropriate treatment of hyponatremia can add to the problem. The diagnosis and management of salt and water abnormalities in critically ill patients is often challenging. The increasing knowledge about aquaporins and the role of vasopressin in water metabolism has enhanced our understanding of these disorders. The authors have outlined the general approach to the diagnosis and management of hyponatremia. A systematic approach by clinicians, using a detailed history, physical examination, and relevant diagnostic tests, will assist in efficient management of salt and water problems.

Abstract
The chest X-ray (CXR) is an important diagnostic tool in diagnosing and monitoring a spectrum of diseases. Despite our universal reliance on the CXR, our ability to confidently diagnose and accurately document our findings can be unreliable. We sought to assess the diagnostic accuracy and certainty of making a diagnosis based on 10 short clinical histories with one CXR each. We conclude from our study that specialist registrars (StRs) and consultants scored the highest marks with the highest average certainty levels. Junior trainees felt least certain about making their diagnosis and were less likely to be correct. We recommend that StRs and consultants review all the CXRs requested to ensure accuracy of diagnosis. There also needs to be discussion with the Joint Royal Colleges of Physicians Training Board (JRCPTB) about the need of including a separate CXR competency as part of a trainee's generic curriculum on the e-portfolio, something which is currently lacking.

Abstract
BACKGROUND Central venous cuffed tunnel catheters are commonly used for short term or long term hemodialysis access. However, catheter-associated bacteremia is a common complication. It has been suggested that the addition of antibiotics to the catheter during the interdialytic interval results in a decrease in bacterial colonization and thereby a decrease in catheter associated infections. To test this hypothesis, a prospective, randomized study was performed comparing a gentamicin citrate mixture to standard heparin as the catheter lock. The effect of covering the catheter hub in a sterile bag on the infection rate was additionally tested. METHODS From January 1999 to April 2000, all patients who underwent tunnel catheter placement or change (55 catheters) in the Nephrology Interventional Laboratory at Louisiana State University Health Sciences Center in Shreveport, were prospectively randomized as follows: group 1 (n=14): Antibiotic lock with tricitrasol (46.7%), gentamicin (40 mg/ml) and saline in a ratio of 1:5:5 and catheter hub covered with a sterile plastic bag after cleaning with a 10% povidone iodine solution; group 2 (n=22): Heparin lock and sterile plastic bag over catheter hub after cleaning with povidone iodine; and group 3 (n=19): Heparin lock alone. The primary end points of the study were catheter-associated bacteremia and thrombosis. Catheter loss due to access maturation, transplant or transfer were censored. RESULTS There were a total of 4,805 at risk patient-days. The total number of catheter associated bacteremias were one in group 1, four in group 2 and four in group 3. The number of catheter associated bacteremias per 1000 patient-days in each group was 0.62, 3.05, and 2.11 respectively. The sixty day percent survival of catheters in each group was 74 +/- 12, 55 +/- 12 and 59 +/- 11 respectively. CONCLUSIONS 1) Tricitrasol and gentamicin as an antibiotic lock reduced the incidence of catheter associated bacteremia; 2) Covering the catheter hub with a sterile bag did not provide an additional advantage; 3) The antibiotic lock improved overall survival of catheters.

Abstract
INTRODUCTION The Memokath 051™ is a semipermanent inert metal alloy ureteric stent which can bridge strictures and, compared to double J stents, causes less bladder irritation and pain, is more resistant to external compression forces and may be more effective in patients with malignant ureteric obstruction. We present our experience with this novel stent in such cases. METHODS All suitable patients referred to us with malignancy-associated ureteric strictures over a 4-year period had ureteric Memokath 051™ stents inserted. Data on aetiology and position of the strictures as well as length of the Memokath stents used and their efficacy and complications were recorded prospectively. RESULTS 42 ureteric Memokath 051™ stents were inserted in 37 patients (mean age 64 years). 40.5% of strictures were related to gynaecological cancer, 21% to bowel cancer, 14% were post radiation, 14% occurred in prostate cancer patients and 9.5% were found in other cancers. The mean follow-up was 22 months (range 5-60 months). The main complications were stent migrations in 5, urinary tract infections in 3 and blockage of stent due to progressive transitional cell carcinoma of the ureter in 2 cases. CONCLUSION Memokath 051™ ureteric stents are safe, effective and durable in the long-term treatment of malignant strictures.

Abstract
Leeches are a class of segmented invertebrates, known for their blood-feeding habits and used in phlebotomy to treat various ailments since antiquity. In Europe, medicinal leeches have recently been rediscovered and are used by maxillofacial and other microsurgeons to aid salvage of compromised venous engorged tissue and amputations, such as digits, ears, and nasal tips. Because of their important salivary components, blood-sucking (sanguivorous) leeches, such as Hirudo medicinalis and related species, have engendered great interest from pharmaceutical companies searching for anticoagulants to prevent blood clotting during microsurgeries. Scientific research reveals that the beneficial effects of leeching, in addition to decongestion, include injection of a cocktail of several medicinally useful bioactive molecules present in their saliva. Owing to its therapeutic potential, the research is continuing as many new salivary compounds are being isolated and synthesized.

Abstract
Primary smooth muscle tumor of the pleura is exceptionally rare. The authors describe a primary smooth muscle tumor of the pleura that was discovered incidentally on chest X-ray in a 73-year-old man. Magnetic resonance imaging demonstrated a 12 x 18 x 15-cm pleura-based mass arising from the posterior mediastinum. Computerized tomography (CT) guided needle cores from the pleura showed a primary smooth muscle tumor of undetermined malignant potential. Further excision of the whole tumor showed an intimate relation to pleura, and the diagnosis of leiomyosarcoma was made. The clinical, radiological, histopathological, immunohistochemical, and ultrastuctural findings were consistent with a primary smooth muscle tumor of the pleura. This is the seventh case in the literature of a primary smooth muscle tumor of the pleura, which, to the best of the authors' knowledge, is the first such case of the pleura to be diagnosed on CT-guided needle biopsy. In conclusion, this method of investigation is recommended since it is minimally invasive but has a rewarding yield in providing the most likely diagnosis, predicting prognosis, and management planning.

Abstract
e19535 Background: New Tx options have become available on the market or as investigational agents in Canada for relapsed/refractory MM in the last few years. These new Tx options include IMiDs [thalidomide, lenalidomide (Revlimid)] and a proteosome inhibitor [bortezomib (Velcade)]. These new agents are changing both the Tx patterns as well as the clinical outcome of this disease. New combination regimens of both new agents and older generic drugs are also being investigated. Methods: This retrospective analysis included all relapsed/refractory MM Pts who initiated drug Tx between Jul-06 and Jun-07 at Princess Margaret Hospital, Toronto, ON. Historical data collection focused on prior Tx (types), duration and efficacy. Results: This analysis included all prior historical Tx data Dec-96 to Jul-07) from 151 Pts. 62% of Pts were male. Time from diagnosis to 1st initial Tx was 1.7 (SD±4.2) months. Of the 25 Pts who had cytogenetics analyzed by FISH, 6 Pts had deletion 13q, 4 Pts had translocation involving chromosome 14 [including partner gene translocations on chromosomes 4 (2 Pts) and 11 (1 Pt)] and no Pts had deletion p53. 76.8% of Pts received at least 1 stem cell transplant (SCT) with 7.9% of Pts receiving 2 SCTs prior to current study Tx. Historical 1st line & 2nd line Txs, respectively, were cyclophosphamide ± steroid (14.6%, 28.3%), IMiD-based (17.2%, 40.2%), melphalan + prednisone (14.6%, 9.8%), vincristine + adriamycin + dex (69.5%, 5.4%), steroid monotherapy (23.8%, 22.8%), bortezomib based (0.7%, 15.2%), and other (6.0%, 6.5%). Overall best RRs (≥MR) during historical 1st & 2nd line Tx were 92.6% and 83.3% (≥ minimal response), respectively, with a corresponding 15.6% & 11.9% combined CR + near CR rate, respectively, across all regimens reported. Historical median TTP following 1st, 2nd, and 3rd line of Tx were 21.5 (95% CI: 18.9, 24.3), 20.2 (95% CI: 16.9, 22.8), and 10.0 (95% CI: 5.5, 16.6) months, respectively. Conclusions: This is the first known historical analysis of real world MM Txs in Canada from a large tertiary centre. Historical data suggests the common use of older drugs such as alkylating agents. This usage pattern may be different than in other countries where the accessibility of newer agents to treat MM is easier than in Canada. [Table: see text]

Abstract
e19503 Background: New Tx options, including IMiDs [thalidomide, lenalidomide (Revlimid)] and bortezomib (Bz) (Velcade), have in the last few years become available on the market or as investigational agents in Canada for relapsed or refractory MM. These new agents are changing the Tx pattern and the clinical outcome of this disease. Methods: This retrospective chart review included all relapsed/refractory MM Pts who initiated drug Tx between Jul-06 and Jun-07 inclusive at Princess Margaret Hospital, Toronto, ON. Results: A total of 151 Pts were treated for relapsed/refractory MM between Jul-06 & Jun-07. 57 Pts (40 receiving IMiD, 14 Bz, 3 other) were on clinical trials and thus not included in the analysis due to proprietary restrictions. Mean age, % male and BSA was 64.8 (SD±9.5) yrs, 68.1%, 1.9 (SD±0.2), respectively. Time from diagnosis to current therapy was 46.3 (SD±24.7) months. Nearly half the Pts were receiving treatment for 1st disease relapse (48.9%), 24.5% for 2nd relapse, 14.9% for 3rd relapse, and the remainder for ≥ 4th relapse. 74.5% of Pts had received at least 1 stem SCT prior to current study Tx. Current Txs included cyclophosphamide ± steroid (36.2%), Bz-based (26.6%), IMiD-based [17.0% (thalidomide only)], steroid monotherapy (13.8%), melphalan + prednisone (1.1%) and other (5.3%). Overall best RR was 43.6%, and 41.5% of Pts experienced PD up to the follow-up period. Mean TTP was 9.6 (SE±0.5) months. 30.9% of Pts received ESAs, 12.8% of Pts required RBC or platelet transfusion, 6.4% of Pts received G-CSF, and 47.9% of Pts received supportive pain medication. 27.7% of Pts required unscheduled hospitalization (56.4% due to MM and 7.7% due to Tx). Incidence of any grade drug-related varicella zoster, increased neuropathic pain, and thromboembolic events were 6.4%, 16.0%, 2.1%, respectively. Four Pts died while on current Tx and 14 died during the follow-up period of up to Dec-07. Conclusions: Bz was rarely used prior to public funding in Jul-06. Since then Bz (either as monotherapy or in combination) is the most commonly used novel Tx outside a clinical study and is replacing the use of the older agents. As the first analysis of current real world MM Txs in Canada from a large tertiary academic centre, this data is reflective of emerging treatment trends. [Table: see text]

Abstract
Peritonitis is the "Achilles heel" of patients on peritoneal dialysis. Fungal peritonitis though not that common is associated with increased morbidity and mortality. We report the first case in the literature of a patient who developed peritonitis caused by Curvularia geniculata. We discuss the reported cases of Curvularia lunata peritonitis in literature and emphasize the early removal of catheter and treatment with intravenous amphotericin B.

Abstract
The pilot study in Punjab, Pakistan was one of the five paired demonstration projects sponsored by FIGO in the "Save the Mothers" maternal mortality project. The goal of the project was to bring basic and comprehensive emergency obstetric care (EmOC) to a semiurban and rural area some 30 km from Lahore, where effectively there was none. The aim was to achieve this by using the existing facilities within the rural health system without the deployment of extra specialist staff other than as initial facilitators. This report shows trebling of some performance indicators and an improvement in met need. There is coincidentally a similar increase in the uptake of general medical services. Reducing maternal mortality requires building local capacity for EmOC; the essential components being the premises, trained personnel, equipment, and availability of drugs and blood. Availability and provision of EmOC coupled with changes in the attitude of the population resulted in marked improvement of process indicators.

Abstract
Single-nucleotide polymorphisms in the genes that code for coagulation factor V (factor V (Leiden)) and II (prothrombin G20210A), as well as the methyltetrahydrofolate reductase (MTHFR) have been implicated in the majority of cases of hereditary thrombophilia. In our hemodialysis patient population, comprised mainly of African Americans, we have seen a high incidence of early vascular access thrombosis without any identifiable predisposing factors. In some instances, there is recurrent access thrombosis that may be related to an inherited condition. In this study we evaluated the presence of these gene mutations and their association with increased risk of recurrent vascular access thrombosis in our hemodialysis patient population. Our results show that factor V Leiden and factor II prothrombin point mutations did not appear to increase the risk of vascular access thrombosis in African Americans with end-stage renal disease on hemodialysis. Patients heterozygous for the MTHFR gene, also did not show a significant increased risk for synthetic graft thrombosis.

Abstract
We report the case of a young white male who developed the nephrotic syndrome after being stung by a wasp. A percutaneous renal biopsy was done revealing minimal change glomerulonephritis. The patient was treated with oral prednisone with resolution of proteinuria. Corticosteroids were gradually tapered, the patient did not experience a relapse, and remains in good health with normal renal function. Herein, we also include a review of the literature on wasp bite associated nephrotic syndrome in patients who underwent a renal biopsy.

Abstract
Isothermal microcalorimetry may be used to determine kinetic and thermodynamic parameters for chemical reactions. This paper reports rate constants, determined as a function of temperature, and the activation enthalpy for the degradation of solid benzoyl peroxide as determined by isothermal microcalorimetry. Studies were conducted on aqueous suspension phase, solid benzoyl peroxide. In addition, supporting evidence is cited from work carried out in this laboratory on the solution phase degradation of benzoyl peroxide using UV-visible spectrophotometry. The activation energy obtained by microcalorimetry was E(a)=137.8+/-6.6 kJ mol(-1) and the activation energy obtained from UV-visible spectrophotometry was E(a)=112.7+/-4.2 kJ mol(-1).

Abstract
Recent developments in the analysis of microcalorimetric data output allow the possibility of determining both thermodynamic and kinetic parameters for complex reaction systems. Such experiments routinely take around 50 h, hence qualifying for the description rapid. The methods have earlier been applied to a study of the stability of benzoyl peroxide itself in aqueous suspension. This paper reports the results of isothermal microcalorimetric study of the stability of benzoyl peroxide in the presence of a wide range of excipients and in formulated materials. The results are shown to assist in formulation design, are achieved rapidly and are derived from direct experimental study of the complex systems themselves. That is, no ancillary information is required nor are the studies invasive or destructive.

Abstract
Our understanding of ocular manifestations in immunologic and rheumatologic inflammatory disorders has continued to expand over this past year. Studies that support the proposed immunologic pathogenesis of Vogt-Koyanagi-Harada disease are discussed. An article on the course of Behçet's disease is reviewed as well as another article discussing severe visual loss in patients with a familial occurrence of Behçet's disease. The prognostic factors for visual outcome in sarcoid uveitis are presented. An unusual case of giant cell arteritis and the most significant symptoms and diagnostic clues in helping make the diagnosis of giant cell arteritis are discussed.
