RESUMO
Thalassemia major is one of the health problems in Iraq, especially in Kurdistan. Pre-marriage mandatory preventive screening program was established in Kurdistan in 2008, which allowed us to study the prevalence of different hemoglobinopathies among newly married young adults in this region. A total of 1154 subjects (577 couples) attending the Koya district, premarital Health center, were screened using red cell indices. Those who had mean corpuscular volume (MCV)<80 fl and mean corpuscular hemoglobin (MCH)<27 pg had high-performance liquid chromatography and iron studies. Out of 1154 individuals that were evaluated, 183 (11.9%) had low MCV and MCH. Of the former 183 subjects, 69 (5.97%) had ß-thalassemia trait, 10 (0.86%) had δß-thalassemia trait, and no other hemoglobinopathies were recorded in our study. There was second-degree consanguinity in 4.7% of all 577 couples. In two couples, both partners had ß-thalassemia trait and both were consanguineous. Both couples decided to separate after counseling. Based on the current study, the role of the premarital screening program in decreasing the number of new thalassemia major cases among the Kurdish population is laudable. Therefore, mandatory premarital screening is advised in all parts of Iraq.

BACKGROUND AND PURPOSE: Injectable botulinum neurotoxin (BoNT) is the principal effective treatment for blepharospasm (BSP). This trial explores the safety and efficacy of topical acetyl hexapeptide-8 (AH8), a competitive SNAP25 inhibitor, as a potential new therapy in BSP. METHODS: Double-blind, placebo-controlled, randomized trial of daily topical application of AH8 in 24 patients with BSP. The primary outcome was time to return to baseline Jankovic Blepharospasm Rating Scale (JBRS) after a BoNT injection simultaneously with the initiation of AH8. Patients displaying a strictly regular pattern of response to 3-monthly injections of BoNT were included. RESULTS: There were no significant adverse events. There was a trend for longer time until return to baseline JBRS after injection in the active group compared to placebo (3.7 months vs. 3.0 months), and for better scores in the active group. One-third (4/12) of the patients in the active group had a considerable extension of symptom control after BoNT (range: 3.3-7.1 months). CONCLUSIONS: Topical AH8 is safe and promising for extending the duration of action of BoNT therapy for BSP.

BACKGROUND: Indwelling urinary catheters (IDCs) are a common invasive device in hospitalised patients. Their use is associated with increased risks of developing catheter associated urinary tract infections (CAUTI), and blood stream infections (BSI). AIMS: To examine the characteristics and outcomes of adult inpatients with an IDC inserted in hospital and identify risk factors for developing CAUTI and BSI. METHODS: We performed a retrospective observational study of 430 patients with IDC admitted to medical and surgical units of a leading (tertiary) hospital between Nov 2019 till April 2020. Multiple logistic regression analysis was performed to determine independent risk factors for developing urinary tract infection and blood stream infection. RESULTS: The prevalence of CAUTI in our study was 7.4%. Results of multiple logistic regression indicated that with each day of IDC in situ, the likelihood of UTI development increased by 9% (OR 1.09; 95% CI 1.00 to 1.18; p = 0.03). Age, gender, and catheter reinsertion were not associated with UTI development. CONCLUSIONS: Longer duration of IDC was associated with elevated risk of developing CAUTI. CAUTI rates were higher than some of those previously published. There was no statistical significance in frequency of CAUTI between medical and surgical patients. No statistically significant variables that contributed to the development of BSI were found. Interventions targeted at reducing catheter days should be used to improve CAUTI rates.

The Arabian tahr (Arabitragus jayakari) endemic to mountains of northern Oman and the United Arab Emirates, however, the species is faced with significant threats to its population. Because of its small and dwindling population, it is listed as Endangered. Here, we sequenced and assembled the mitochondrial (mt) genome of A. jayakari into 16,485 bp with 39.6% GC content. It also contains 13 protein-coding genes, 22 tRNA genes, and two rRNA genes. Phylogenetic analysis of A. jayakari with related 12 species mt genomes showed that A. jayakari forms a monophyletic clade with Hemitragus jayakri. In the current context of a changing environment, evolutionary analysis based on mitochondrial genome will aid in identifying evolutionary changes among different species and analyzing shared gene pools to counteract threats.
RESUMO
Adrenocortical carcinomas (ACCs) are rare malignancies with an incidence of one to two per million per year. Aldosterone-producing ACCs (APACs) are extremely rare with an incidence less than 1%. We describe a rare case of APAC, presenting with episodic lower-limb weakness and hypertension. Our patient was found to have serum aldosterone levels of 20.8 ng/dL (2.5-15.2) with persistent hypokalaemia and a 9.7×8.3×7.7 cm right adrenal mass, which was suspicious of malignancy on evaluation. He underwent a complete surgical resection which confirmed the diagnosis of ACC and normalised his aldosterone and potassium levels. He was then subjected to postoperative chemotherapy. Postoperative adjuvant chemotherapy with mitotane has a role in preventing recurrence.

BACKGROUND: Smoking is a well-known related factor for many health problems in a human being through different ways of exposure. OBJECTIVES: Thie aim of the study was to examine the effects of different types of cigarette smoking on hemoglobin level, high sensitive C-Reactive Protein (hsCRP), Malondialdehyde (MDA), and IgE levels in healthy adult subjects. METHODS: One hundred seventy-one healthy adult females and males were included in this study. They divided into four groups: cigarette, shisha, passive smokers, and non-smokers groups. Serum samples from all groups analyzed for hemoglobin, hsCRP, IgE, and malondialdehyde level. RESULTS: The mean MDA, IgE, and hemoglobin levels significantly increased in both smokers (cigarette and Shisha groups) and passive smokers than in non-smokers group (p<0.05). The hsCRP levels were significantly increased (p<0.05) in cigarette and Shisha smokers compared to non-smokers. At the same time, there was a non-significant relationship between passive smoker in comparison to non-smokers (p>0.05). CONCLUSION: This study concluded that smoking, including cigarette and shisha, even passive smoking harmed health through increasing Malondialdehyde, serum IgE and hs-CRP levels in the body.

BACKGROUND: The presence of subvisible particles (SVPs) in parenteral formulations of biologics is a major challenge in the development of therapeutic protein formulations. Distinction between proteinaceous and non-proteinaceous SVPs is vital in monitoring formulation stability. METHODS: The current compendial method based on light obscuration (LO) has limitations in the analysis of translucent/low refractive index particles. A number of attempts have been made to develop an unambiguous method to characterize SVPs, albeit with limited success. RESULTS: Herein, we describe a robust method that characterizes and distinguishes both potentially proteinaceous and non-proteinaceous SVPs in protein formulations using Microflow imaging (MFI) in conjunction with the MVAS software (MFI View Analysis Suite), developed by ProteinSimple. The method utilizes two Intensity parameters and a morphological filter that successfully distinguishes proteinaceous SVPs from non-proteinaceous SVPs and mixed aggregates. CONCLUSION: The MFI generated raw data of a protein sample is processed through Lumetics LINK software that applies an in-house developed filter to separate proteinaceous from the rest of the particulates.

Glioblastoma multiforme (GBM) is a high grade glial tumor, primarily located in cerebral hemispheres. The most common clinical presentations are slowly progressive neurological deficit such as motor weakness, seizure, and headaches that last less than three months. Calvarium and extra-axial invasion are very rare and generally occur after a brain biopsy or surgery, or secondary to radiotherapy of primary intra-axial glial tumors. We report a case of GBM with calvarium involvement in a 60-year-old man who presented with a frontal bump and left-sided clumsiness. Imaging studies revealed a tumoral lesion that destroyed the frontal bone with white matter involvement of the frontal lobe and extension into the corpus callosum. Histopathological examination of intra-axial and extra-axial lesions revealed pleomorphic high-grade tumor with large areas of necrosis and hemorrhage. Immunohistochemical (IHC) studies confirmed GBM that spread directly into the dura, galea, and calvarium (positive reaction for GFAP, S-100, CD68, OLIG2, and p53). The patient was treated with radiotherapy (60Gy/30 fractions) and concomitant temozolomide. Unfortunately, the patient died seven months after the initial diagnosis.

The synthetic polynucleotide polyadenylic-polyuridylic acid (polyA:polyU) has shown antitumor activity in murine studies and human breast cancer. PolyA:polyU was evaluated in 25 cancer patients receiving weekly intravenous doses between 3 and 600 mg/m2. PolyA:polyU was well tolerated up to 600 mg/m2, with no doselimiting toxicity (all < grade 3). Side effects included mild elevation in temperature, fatigue, and mild hyperglycemia. No changes outside of the normal range in hematocrit, WBC count, platelet count, total bilirubin, or alkaline phosphatase were observed. Of 25 patients, 18 completed at least one cycle of 6 weeks, and 5 completed two cycles (median 6 weeks). Four patients had stable disease over 11-13 weeks of treatment, and no clinical responses were observed. At 24 h after the first treatment, there were no significant increases in biologic response (beta 2-microglobulin and neopterin in serum, or 2',5'-oligoadenylate synthetase in peripheral blood mononuclear cells). A small increase in beta 2-microglobulin was observed 24 h after the week 3 treatment (1.1-fold, p < 0.01). By the third week of treatment, 2-5A synthetase levels decreased slightly (to 80% of baseline, p < 0.01). No changes in cytokines IL-6, IL-12, tumor necrosis factor (TNF), or IL-2 receptor in serum were detected after 24 h of treatment. Thus, at these doses, polyA:polyU had no marked modulation on biologic responses in vivo, although this preparation significantly induced 2-5A synthetase in peripheral blood mononuclear cells in vitro. PolyA:polyU was well tolerated. An MTD was not reached but was greater than 600 mg/m2 on this weekly schedule.

Based on preclinical studies demonstrating synergy between gallium and hydroxyurea, we evaluated the efficacy and toxicity of continuous intravenous gallium nitrate in combination with oral hydroxyurea in patients with refractory non-Hodgkin's lymphoma. Fourteen patients, median age 64 years (range 53-89), with stage III or IV low- or intermediate-grade lymphoma were treated with gallium nitrate and hydroxyurea in combination for 7 days at four different dose levels: (a) gallium nitrate, 200 mg/m2/day; hydroxyurea, 500 mg/day; (b) gallium nitrate, 250 mg/m2/day; hydroxyurea, 1,000 mg/day; (c) gallium nitrate, 300 mg/m2/day; hydroxyurea, 1,000 mg/day; and (d) gallium nitrate, 350 mg/m2/day, hydroxyurea, 1,000 mg/day. All patients had progressive disease and had been heavily pretreated. Six of 14 patients had objective tumor regression following treatment (one complete response, one near-complete response, and four partial responses) with a median duration of response of 7 weeks (range 3-38 weeks). An additional four patients had minor responses. Responses occurred at all dose levels and in both low- and intermediate-grade histologic subtypes. The predominant toxicities encountered were anemia and reversible nephrotoxicity. Combination gallium nitrate and hydroxyurea has significant activity in lymphoma and is well tolerated even by elderly patients. Because of the lack of cross-resistance to other drugs and the potential synergistic antineoplastic activity, gallium nitrate and hydroxyurea should be further evaluated in combination with other chemotherapeutic agents.

Goniothalamus scortechinii, Andrographis paniculata and Aralidium pinnatifidum were selected for the study based on their ethnomedicinal values. They were screened for anti-malarial activity towards Plasmodium falciparum in vitro using the lactate dehydrogenase (LDH) assay. The crude extract of G. scortechinii exhibited the most potent schizonticidal activity compared to the other extracts. It is effective against both the chloroquine resistant isolate, Gombak A and the sensitive strain, D10 of Plasmodium falciparum. Furthermore a better IC(50) value was obtained against the resistant strain, (9 microg/ml) compared to the sensitive strain, 40 microg/ml. When the crude extract was fractionated into 3 fractions, the chloroform fraction yielded the best activity, exhibiting equipotency against both strains of parasite used; IC(50) of 23.53 microg/ml against Gombak A and 21.06 microg/ml against D10.

Kidneys are complex organs with multiple vital functions. They are an essential part of the urinary system and also are necessary for regulation of body homeostasis like electrolytes, acid base balance and blood pressure. Diagnosis of renal injuries is based on clinical and histopathologic features. In a descriptive cross-sectional study conducted in Shahid Sadoughi Hospital, Yazd, Iran, pathology reports of all renal biopsies, by light microscopic examination, immunofluorecence and electron microscopy (EM) were perused. Data were registered in a questionnaire with questions on patients' demographic information such as age, sex and also questions on clinical signs and symptoms and pathologic findings such as H & E, Immunofluorescence (IF) and electron microscopy. All data were analyzed by SPSS-15 software with descriptive analysis. A total of 80 patients were included in this study, 42 men (52.5%) and 38 women (47.5%), aged 19-73 years (mean: 40.59 ± 16.36). Based on H & E, IF and electron microscopic findings, it seems that in 26.4% of cases the IFM was necessary and in 67.6% was helpful and in 6% was unnecessary for diagnosis. Between 42 patients, EM was necessary in 12% of patients, while in 71.5% was helpful and in 16.5% was unnecessary. Based on IFM the most common renal disease was FSGS (focal segmental glomerulosclerosis) with mean age of 41.3 years. IFM was necessary in RPGN, chronic glomerulonephritis, mesangial hypercellularity, minimal change disease, IgA nephropathy, and was helpful in FSGS, MPGN, tubulointerstitial nephritis, diffuse sclerosing glomerulonephritis and membranous glomerulopathy but was unnecessary in lupus nephritis. EM was necessary in mesangial hypercellularity, chronic glomerulonephritis and diffuse sclerosing glomerulopathy and was helpful in FSGS, MPGN, lupus nephritis and membranous glomerulopathy while it was unnecessary in minimal change disease and IgA nephropathy.

BACKGROUND: Refusal of the oral polio vaccine (OPV) is a difficulty faced by the Polio Eradication Initiative (PEI) in multiple endemic areas, including the Khyber Pakhtunkhwa Province (KPP), Pakistan. In 2007, we investigated community perceptions of the OPV and estimated the prevalence of OPV refusal in three districts in Swat Valley, KPP, a polio-endemic area. METHODS: Qualitative data concerning community perceptions were collected by focus group discussions among lady health workers (LHWs) and mothers with children <1 year old and by key informant interviews with local health managers and officials. Quantitative data collection followed using a questionnaire survey of 200 LHWs and a cluster sampling survey of 210 mothers (per district) with children <1 year old. RESULTS: The qualitative assessments identified the grounded theory of OPV refusal involving facts known by the residents that are related to the OPV (too frequent OPV campaigns, an OPV boycott in northern Nigeria in 2003 and that birth control is viewed as is against Islam), the local interpretations of these facts (perceptions that OPV contained birth control or pork, that OPV was a foreign/central plot against Muslims, and that the vaccination was against the Hadith and the fate determined by God) and different manifestations of OPV refusal. Among the three districts studied, the proportion of LHWs who encountered OPV refusal ranged from 0 to 33%, whereas among the districts, the proportions of mothers unwilling to give OPV to their children ranged from 0.5 to 5.7%. Refusal of other injectable vaccines was almost equally prevalent for reasons that were very similar. CONCLUSIONS: The PEI needs to reflect local value system in the path to polio eradication in the studied districts in the Swat Valley. The religious and cultural values as well as the interpretation of the international political situation are of particular importance.

Hypertrophy of adenoids is usually caused by repeated throat infections, especially viral and bacterial infections, that in microscopic examination reveal reactive lymphoid follicular hyperplasia. Herein, we present an 11-year-old boy who developed hearing loss in his left ear three months before admission, and in direct examination the adenoids were hypertrophied. Histopathological study of the resected adenoid revealed caseating granulomatous inflammation. Based on histopathological and clinical findings, primary tuberculosis of adenoids was suggested which was confirmed by PCR.

The pandemic spread of tuberculosis (TB) and human immunodeficiency virus (HIV) represents a serious world problem. The diagnosis of TB in developing countries remains difficult, particularly in patients with concomitant HIV infection. Anergia to tuberculin frequently occurs in HIV-positive patients with pulmonary or extrapulmonary disease, and radiographic images are atypical or nondiagnostic. Children are often in an even more unfavorable situation: they cannot expectorate, and the biological samples required for bacteriological examination and culture are more difficult to obtain. We present in this work the correlation between the presence of serum antimycobacterial antibodies [as demonstrated by an in-house enzyme-linked immunosorbent assay (ELISA)] in 41 out of 279 HIV-infected children, and clinical, bacteriological, radiological, and pathological data that support the diagnosis of TB in these children. The prevalence of antimycobacterial antibodies in our group of HIV-positive children was 23.3%. In only 4 of the total cases investigated could the diagnosis of TB not be supported by the results of standard tests for TB. The control group showed an insignificant interference from bacillus Calmette-Guerin (BCG) vaccination.
