RESUMEN

This study was conducted to describe the morphometrics of nuchal ligament and investigate the effects of different neck and body positions on the nuchal ligament in greyhounds. Nine adult greyhounds cadavers without any locomotion abnormalities were dissected through the neck musculature on the left side to expose the nuchal ligament. Three pins were placed to mark regions of interest on the nuchal ligament: at one cm cranial to the site of origin (the most dorsal point of the spinous process of the first thoracic vertebra), at the midpoint of the nuchal ligament and one cm caudal to the nuchal ligament site of insertion (close to the caudal aspect of the spinous process of the axis). Each cadaver was positioned on a masonite board and placed on a table on the floor in their lateral recumbency and seven different standardized body positions; P1-P7 were mimicked using goniometers and metal wires. Photographs were taken by positioning and fixing the camera above the nuchal ligament region. The length and widths (W1, W2 and W3) of nuchal ligament were measured using Image Pro software (Image-Pro Express version 5.0) on standardized photographs of each of seven different body and neck positions. The length of nuchal ligament in relation to the neutral position (P1) was less (- 7%, p > 0·05) in P6 (neck elevated) and increased in all other positions (+1%, p > 0·05 for P2, +19%, p < 0·05 for P3, +37%, p < 0·05 for P4, +1%, p > 0·05 for P5, +40%, p < 0·05 for P7). Nuchal ligament width at the middle (W2) decreased significantly with P4 (- 26%, p < 0·05), and P7 (- 32%, p < 0·05). Also, nuchal ligament width at the site of origin (W3) decreased significantly with P4 (- 24%, p < 0·05) and P7 (-35%, p < 0·05). These findings reflect the need for clinical and biomechanical studies to describe in-depth the gross anatomy of the nuchal ligament in greyhounds. They suggest that different neck and body positions change the shape, and hence, the function of the nuchal ligament during movement.

RESUMEN

Little attention has been paid to the normal fusion of the vertebrae of greyhounds despite the common occurrence of sacrocaudal fusion. The current study aimed to investigate and provide data on the morphology of different types of fused sacra (B, C and D) in greyhounds and also to determine the potential association between the sex, body mass and morphology of fused sacra (S. Weight, S. Length and S. Width) in greyhounds. The sacra were collected from 171 greyhounds from Melbourne, Australia. After classifying the sacra based on the occurrence and types of the sacrocaudal fusion, they were measured for weight of the sacrum, length of sacrum and the width of sacrum. Multiple linear regression analyses were used to quantify the association between weight of the sacrum (as the outcome variable) type of sacrum (A, B, C and D), body mass and sex (as explanatory variables). The results proved that there are measurable differences between each type of fused sacra (B, C and D) and the standard sacra (A). In addition, this study showed that sex or body mass do not influence the occurrence of different types of fusion. The results of this study showed that the occurrence of sacrocaudal fusions was independent of body size in this population of greyhounds. Sacrocaudal fusion might affect the biomechanics in greyhounds independently of effects of body size.

RESUMEN

The aim of this study was to compare efficacy and safety of different combination regimens in re-treatment of HCV in the setting of inaccessibility of resistance testing. This real-life prospective study included 86 chronic HCV infected patients who experienced failure of treatment treated at Faculty of Medicine Ain shams Research Institute (MASRI) since 2018. 64% of the patients were males, with median age 50.2 years. They were re-treated using 1 of 3 proposed regimens of DAA combinations. One group received PAR/OMB/SOF/RBV for 12 weeks, another group received SOF/DAC/SIM/RBV for 12 weeks and a third received SOF/DAC/RBV for 24 weeks. Response to different regimens was assessed by comparing sustained virologic response (SVR) of each. Monitoring the occurrence of adverse events was performed. SVR was achieved in all but 3 patients (96.5% SVR), one in the SOF/DAC/SIM/RBV group and two in the SOF/DAC/RBV group. The group receiving RBV had more anaemia and hyperbilirubinemia. The first treatment regimen used was a significant predictor to SVR achievement. This study presents alternative treatment regimens for re-treatment of HCV patients in areas with limited resources in the case of non-availability of other regimens as velpatasvir, voxilaprevir, grazoprevir, elbasvir.

RESUMEN

This study was conducted to provide structural and morphological data on the sacra of greyhounds. Descriptive quantitative investigation was carried out on 171 sacra of greyhound`s cadavers and then classified into standard and fused sacra based on the number of fused sacral vertebrae. The weight, length and width of sacrum of sacra were measured. Both standard (59%) and fused sacra (41%) were identified. The average length and width of the standard sacrum were found to be 46.14 ± 2.53 mm and 57.89 ± 3.54 mm, respectively. The sacral length was 1.61-mm longer in males (p < .01), and the sacral width was 0.46-mm shorter in males but not significant (p = .51). The average weight of a standard sacrum was 26.54 ± 4.55 g and was 1.18 g heavier in males but not statistically significant (p = .24). Results showed that one-kilogram increase in the body mass was associated with a 0.3 mm (p < .001) increase in sacral length, and a 0.54 mm (p < .001) increase in sacral width, respectively. The morphological data of the standard and fused sacra provided in this study might help the veterinary community to improve treatment and rehabilitation and help the trainer to design the right training protocol for racing greyhounds. In addition, the results of this study are a step to understand the sacrum's functions and how the greyhound's body functions and future studies are required to investigate the biological importance of these findings.

RESUMEN

The lumbosacral joint is where the 7th lumbar vertebra (L.7) articulates within the sacrum. It is a clinically important area in the dog because of its relatively large range of motion. The current study aims to determine the possible differences in the length of the L.7 vertebra and the angle of the lumbosacral junction among greyhounds of standard and those of fused sacra, and to determine the potential association of sex, body mass and type of fused sacrum (standard and fused) on the morphology of the L.7 vertebra and the angle of the lumbosacral junction. Radiographs of 55 greyhound cadavers were used for radiographing; all radiographic images were stored and measured using X-ray acquisition software, and then analysed using descriptive statistics, multiple linear regression and logistic regression. The results of this study showed a significant increase (p < .008) in the length of the L.7 vertebra and the angle of the lumbosacral junction (p < .028) in greyhounds with fused sacra comparing with those of standard sacra, but the L.6 length was not significant (p = .431). Differences have been found in the length of L.7 vertebra and the angle of the lumbosacral junction in greyhounds. It was found that in greyhounds, any variation in the sacrum's anatomical features may alter the structure of the surrounding anatomical structures such as the L.7 vertebra and lumbosacral junction.

RESUMEN

Carpal conformation is often considered as a contributory factor to performance and lameness in the horse; however, few attempts have been made to objectively measure radiographic variations of carpal conformation in horses due to insufficient measurable carpal parameters. This pilot study used carpal radiographic images acquired from 10 cadaveric equine forelimbs transected at the antebrachial midshaft from 7 adult horses (7.2 ± 2.6 years), positioned at 'zero lateromedial' (ZLM) and 'zero dorsopalmar' (ZDP) views, to investigate the anatomy of the equine carpus and develop parameters that could be objectively used to assess carpal conformation in horses. Dorsal carpal angle (DCA: 176.61 ± 0.66º), distal radial slope carpal angle (DRSCA: 145.59 ± 2.19º), intermediate carpal bone proximal tuberosity-radial angle (CiPxTRA: 115.69 ± 3.15º) and third carpal bone palmar facet angle (C3PalFCA: 84.43 ± 1.13º) were all developed from the ZLM view while medial carpal angle (MCA: 183.34 ± 1.02º), disto-dorsal slope angle of the third carpal bone (C3DDSA: 8.27 ± 0.92º) and width ratio of distal radius to proximal metacarpus (WDR:WPM = 1.13±0.03) were 3 of the 10 parameters developed from the ZDP view. Easy to identify and measurable parameters will help to provide quantitative assessment of carpal conformation in the horse with potential of eliminating subjective observational variation errors between clinicians. These newly developed parameters will be useful in further studies to measure variations in the conformation of the equine carpus in live horses and comparison between subjective visual assessment and objective radiographic evaluation methods.

RESUMEN

BACKGROUND: Patients' experience of symptoms often goes undetected during consultation in an outpatient clinic, and the use of a patient-reported outcome measure (PRO) in such a setting could be useful to aid treatment decision-making. A new PRO measure, the HM-PRO (Hematological Malignancy Specific Patient-Reported Outcome Measure) has been recently developed to evaluate hematological malignancy (HM) patients' health-related quality of life (HRQoL) and their symptom experience in daily clinical practice as well as in research. The objectives of the study were to assess: the internal consistency of the scores for Part A (impact) and its four domains (physical behavior; social well-being; emotional behavior; and eating and drinking habits) and Part B (signs and symptoms); and the test-retest reliability of the individual items of the newly developed hematological malignancy specific composite measure, the HM-PRO. METHODS: This was a prospective longitudinal observational study where 150 patients with different HMs and different stage of disease (male n = 98 (65.3%); mean age 64.9 ± 14.4 years, range 17.9-89.2 years; mean time since diagnosis 3.7 ± 4.9 years, range 0.04-25.8 years) completed the HM-PRO at baseline (assessment 1 at t1) and after 7 days (assessment 2 at t2). Data analysis was performed using IBMSPSS 23 statistical software. RESULTS: The Cronbach's alpha estimates of the HM-PRO for both assessment points (t1 and t2) were above 0.9 for Part A, and above 0.8 for Part B, showing strong stability of the measurement. The level of agreement for the reproducibility between the two assessments, using intra-class correlation coefficients (ICC), was very strong with Part A: ICC = 0.93 (95% CI = 0.90-0.95), and Part B: ICC = 0.91 (0.88-0.93). The ICC for the four domains of Part A ranged from 0.85-0.91. The ICC was greater than 0.8 for overall score of Part A and Part B for all the 10 diagnoses, confirming strong reliability. CONCLUSION: This study clearly indicates that the HM-PRO possesses strong test-retest reliability for both Part A and Part B. The Cronbach's alpha confirmed acceptable internal consistency. The extensive reliability testing described in this study supports the generic nature of the HM-PRO for use in hematological malignancies in both routine clinical practice, to aid treatment decisions, as well as in research.

RESUMEN

BACKGROUND: Validity is the ability of an instrument to measure what it claims to measure. It means the degree to which the empirical evidence supports the trustworthiness of interpretations based on the calculated scores. The hematological malignancy (HM) specific patient reported outcome measure (HM-PRO), is a newly developed instrument for use in daily clinical practice as well as in research. This study, provides the evidence for construct validity of the HM-PRO, specifically focusing on the convergent and divergent validity compared to the other established instruments used in hematology. METHODS: This validation study adopted a prospective cross-sectional design where a heterogeneous group of patients diagnosed with different HMs and different disease state were recruited. A total of 905 patients were recruited from seven secondary care hospitals in the UK and online through five patient organizations. Patients were asked to complete the HM-PRO and other cancer specific PRO's, FACT-G and EORTC QLQ C-30. Data analysis was performed using IBM SPSS 23 statistical software. RESULTS: A total of 486 males (53.7%) and 419 females (46.3%), with a mean age of 64.3 (± 12.4) years and mean time since diagnosis of 4.6 ( ± 5.2) were recruited. The total score of Part A of the HM-PRO highly correlated with the five functional scales of the EORTC QLQ-C30 (Physical = -0.71, Role = -0.72, Emotional = -0.64, Cognitive = -0.58, Social = -0.74-p < 0.001). With respect to correlation with FACT-G, the total score of Part A of the HM-PRO highly correlated with Physical (-0.74), Emotional (-0.57), Functional (-0.66) domains and overall score of FACT-G (-0.74). Similarly, the total score of Part B of the HM-PRO highly correlated with three symptoms scales of EORTC QLQ-C30 (Fatigue scale = -0.74, Nausea and Vomiting = -0.52, Pain = -0.59-p < 0.001) and individual symptom items (Dyspnea = 0.51, Insomnia= 0.43, Appetite loss = 0.54-p < 0.001). CONCLUSION: The construct validity evidence presented in this research is a testimony to the HM-PRO's ability to measure HRQoL issues which it intends to measure. This is of utmost importance when a PRO is used in routine clinical practice so that the interpretation of the scores or response to an individual item is understood by the clinicians/nurses as intended by the patients.

RESUMEN

BACKGROUND: Our aim was to identify health-related quality-of-life (HRQoL) issues and symptoms in patients with haematological malignancies (HMs) and develop a conceptual framework to reflect the inter-relation between them. METHODS: A total of 129 patients with HMs were interviewed in a UK multicentre qualitative study. All interviews were audio recorded, transcribed and analysed using NVivo-11. RESULTS: Overall, 34 issues were reported by patients and were grouped into two parts: quality of life (QoL) and symptoms. The most prevalent HRQoL issues were: eating and drinking habits; social life; physical activity; sleep; and psychological well-being. Furthermore, most prevalent disease-related symptoms were: tiredness; feeling unwell; breathlessness; lack of energy; and back pain. The most prevalent treatment side effects were: tiredness; feeling sick; disturbance in sense of taste; and breathlessness. CONCLUSIONS: Both HMs and their treatments have a significant impact on patients' HRQoL, in particular on issues such as job-role change, body image and impact on finances.

RESUMEN

BACKGROUND: Remdesivir, a nucleotide analogue prodrug that inhibits viral RNA polymerases, has shown in vitro activity against SARS-CoV-2. METHODS: We provided remdesivir on a compassionate-use basis to patients hospitalized with Covid-19, the illness caused by infection with SARS-CoV-2. Patients were those with confirmed SARS-CoV-2 infection who had an oxygen saturation of 94% or less while they were breathing ambient air or who were receiving oxygen support. Patients received a 10-day course of remdesivir, consisting of 200 mg administered intravenously on day 1, followed by 100 mg daily for the remaining 9 days of treatment. This report is based on data from patients who received remdesivir during the period from January 25, 2020, through March 7, 2020, and have clinical data for at least 1 subsequent day. RESULTS: Of the 61 patients who received at least one dose of remdesivir, data from 8 could not be analyzed (including 7 patients with no post-treatment data and 1 with a dosing error). Of the 53 patients whose data were analyzed, 22 were in the United States, 22 in Europe or Canada, and 9 in Japan. At baseline, 30 patients (57%) were receiving mechanical ventilation and 4 (8%) were receiving extracorporeal membrane oxygenation. During a median follow-up of 18 days, 36 patients (68%) had an improvement in oxygen-support class, including 17 of 30 patients (57%) receiving mechanical ventilation who were extubated. A total of 25 patients (47%) were discharged, and 7 patients (13%) died; mortality was 18% (6 of 34) among patients receiving invasive ventilation and 5% (1 of 19) among those not receiving invasive ventilation. CONCLUSIONS: In this cohort of patients hospitalized for severe Covid-19 who were treated with compassionate-use remdesivir, clinical improvement was observed in 36 of 53 patients (68%). Measurement of efficacy will require ongoing randomized, placebo-controlled trials of remdesivir therapy. (Funded by Gilead Sciences.).

RESUMEN

BACKGROUND: The quality of life of patients at all stages of hematological malignancy is greatly affected by the disease and its treatment. There is a wide range of health-related quality of life (HRQoL) issues important to these patients. Any new instrument developed to measure HRQoL of such patients should be content valid, i.e., the items should be comprehensively relevant to the patients and their health condition. The aim of the present study was to examine content validity of a hematological malignancy specific patient reported outcome measure (HM-PRO) developed for use in routine clinical practice. METHODS: Following literature review and semi-structured interviews, the generated themes and sub-themes were discussed to develop the prototype version of the HM-PRO. A 4-step approach was used for content validation: initial testing and cognitive interviewing; item rating; content validity panel meeting; final field testing and cognitive interviewing. Additional questions related to patients' perception of recall period and preferred sentence structure (i.e., question or statement) of the items were also asked during cognitive interviews. RESULTS: The content analysis of 129 transcribed semi-structured interviews resulted in the prototype version of the instrument consisting of 58 items grouped into two parts: Part A (impact/HRQoL - 34 items) and Part B (signs and symptoms - 24 items). The initial testing showed intra-class correlation coefficient (ICC) of >0.8 for both Part A and Part B. Item rating for language clarity, completeness, relevance, and response scale by experts and patients showed content validity index for scales average >0.8 for both Part A and Part B, except 0.64 for relevance for Part A by the patient panel. The final testing of the revised version of the instrument showed the Cronbach's alpha value of 0.91 for Part A and 0.76 for Part B, suggesting high internal consistency, and ICC of 0.91 for Part A and 0.76 for Part B. The recall period of "today" for Part-A and "last 3 days" for Part-B were the patients' preferred "recall period." Furthermore, the patients expressed preference to the HM-PRO items as statements. CONCLUSION: The findings of this study confirm that the HM-PRO possesses a strong content validity, includes all the issues important to patients and is easy to read, understand and respond to spontaneously.

RESUMEN

Toxocariasis is a zoonotic disease with a worldwide distribution caused by the parasitic roundworms, Toxocara canis, commonly found in the intestine of dogs. Identification of frequent shedders for Toxocara canis eggs and the associated risk factors overwhelmingly remain an important cornerstone of conducting evidence-based deworming regimens to reduce the environmental contamination with the parasite eggs. The present study was undertaken to prevalence rate of shedding of Toxocara canis eggs in dogs in Egypt combined with the possible risk factors naturally associated with the infection A total number of 296 fecal samples of dogs were collected in the period from July 2016 to June 2017 and properly screened for the presence of possible infection with an. Importantly, The overall prevalence of Toxocara canis eggs was 53.04% whereas, seasonal dynamics, dog breeds, the irregular anthelmintic use, defecation sites, and unconfined management of dogs were among the risk factors with a significant association with Toxocara canis infection. Taken together, our present data reveal the high overall prevalence of Toxocara canis eggs shedding in in several Egyptian provinces and provide novel information that should pay our attention of the local authorities combined with the public engagement towards implementation of effective control strategies against this disease of zoonotic importance.

RESUMEN

Aim: To determine measurement equivalence of paper and electronic application of the hematological malignancy-patient-reported outcome (HM-PRO), a specific measure for the evaluation of patient-reported outcomes in HMs. Patients & methods: Following International Society of Pharmacoeconomics and Outcomes Research ePRO Good Research Practice Task Force guidelines, a total of 193 adult patients with different HMs were recruited into a multicenter prospective study. The paper and the electronic version of the instrument were completed in the outpatient clinics in a randomized crossover design with a 30 min time interval to minimize the learning effect. Those who completed the paper version first, completed the electronic version after 30 min and vice versa. Instrument version and order effects were tested on total score of the two parts of the HM-PRO (Part A: quality of life and Part B: signs & symptoms) in a two-way ANOVA with patients as random effects. Intraclass correlation coefficients (95% CI) and Spearman's rank correlation coefficients were used to evaluate test-retest reliability and reproducibility. The effects of instrument version and order were tested on total score of the two parts of HM-PRO. Results: The questionnaire version and administration order effects were not significant at the 5% level. There were no interactions found between these two factors for HM-PRO (Part A [quality of life]; p = 0.95); and (part B [signs and symptoms]; p = 0.72]. Spearman's rank correlation coefficients were greater than 0.9, and intraclass correlation coefficients ranged from 0.94 to 0.98; furthermore, the scores were not statistically different between the two versions, showing acceptable reliability indexes. Noteworthy, the difference between the completion time for both paper (mean = 6:38 min) and electronic version (mean = 7:29 min) was not statistically significant (n = 100; p = 0.11). Patients did not report any difficulty in completing the electronic version during cognitive interviews and were able to understand and respond spontaneously. Conclusion: Measurement equivalence has been demonstrated for the paper and electronic application of the HM-PRO.

RESUMEN

There is scarce data available on helminth infection of poultry in the region of Aswan province, Upper Egypt. A total of 276 poultry (156 baladi chickens and 120 domestic pigeons) were collected from different villages in Aswan province to screen the presence of intestinal helminths during the period from April 2016 to March 2017. The current investigation revealed that the overall prevalence was 55.79% (154/276). Additionally, 59.09% baladi chickens had mixed infections with four cestodes and three nematodes. Among cestodes, Raillietina tetragona was the most prevalent species (16.02%) followed by Raillietina echinobothrida (10.98%), Cotugnia digonopora (6.41%), and Raillietina cesticillus (1.28%). The most prevalent nematodal species were Heterakis gallinarum (15.38%), Ascaridia galli (8.97%), and Subulura brumpti (1.28%). In pigeons, 52.5% were found to be infected by four cestodes: Raillietina echinobothrida (22.5%), Cotugnia digonopora (13.33%), Raillietina tetragona (9.16%), and Raillietina cesticillus (3.33%) as well as one species of nematodes, Ascaridia columbae (9.16%). There was a close relationship between the occurrence of intestinal helminths and the age of domestic birds revealing that the high prevalence was found in adults rather than young birds. Meanwhile, it has been found that the highest prevalence was found in summer, while the lowest infection rate was recorded in winter. Further studies are needed to determine the effects of the parasites on the health and productivity of poultry in such area.

RESUMEN

New-onset pancytopenia in pregnancy is challenging in the clinical setting particularly as the management and outcome of pregnancy are entirely dependent on the underlying aetiology. In the absence of increased peripheral destruction, for example, hypersplenism, bone marrow (BM) failure should be considered as the cause of pancytopenia. Profound folate or B12 deficiency may result in BM failure and are relatively easy to diagnose and manage. Other causes include aplastic anaemia (AA), infiltration by a haematological malignancy and other non-haematological disorders. We report a 26-year-old woman presenting with severe pancytopenia due to folate deficiency with complete recovery observed after folic acid replacement. This case highlights the importance of recognising folate deficiency as a reversible cause of pancytopenia, since prompt replacement can lead to rapid normalisation of counts with no subsequent clinical sequelae. We also consider the indications for measuring serum folate in pregnancy.

RESUMEN

The present study was the first attempt to survey the diversity of fish zoonotic parasites in the southern region of Saudi Arabia, particularly the Najran area, from October 2012 to October 2013. Approximately 163 fish representing seven species (two of freshwater fish and five of marine fish) were examined for fish-borne trematode metacercariae using the compression technique, and for zoonotic nematode larvae. Adult flukes were obtained from cats experimentally infected with the metacercariae on day 25 post-infection The prevalence of each parasite species was recorded. The parasites found belonged to two taxa: Digenea (Heterophyes heterophyes and Haplorchis pumilio) in muscle tissue; and nematodes (larvae of Capillaria sp.) in the digestive tract. The morphological characteristics of the fish-borne trematode metacercariae and their experimentally obtained adults were described. This is the first report of these parasites in fish in Saudi Arabia. Moreover, Myripristis murdjan presented higher prevalence of Capillaria sp. infection (22.7%), while Haplorchis pumilio was the dominant metacercarial species (7.9%). Although the number of documented cases continues to increase, the overall risk of human infection is slight. The increasing exploitation of the marine environment by humans and the tendency to reduce cooking times when preparing seafood products both increase the chances of becoming infected with these parasites. Furthermore, our results indicate that certain fish production systems are at risk of presenting fish zoonotic parasites, and that control approaches will benefit from understanding these risk factors.

O presente estudo representa a primeira tentativa para investigar a diversidade dos parasitas zoonóticos em peixes na Região Sul da Arábia Saudita, em particular na área de Najran, de outubro de 2012 a outubro de 2013. Aproximadamente, 163 peixes representando sete espécies (duas de água doce e cinco marinhas) foram examinados para as metacercária, dos trematódeos de peixes, usando-se a técnica de compressão e para as larvas de nematoides. Os trematódeos adultos foram obtidos em gatos experimentalmente infectados com metacercárias no 25° dia após a infecção. A prevalência de cada espécie parasita foi registrada. Os parasitas encontrados pertenciam a dois taxa: Digenea (Heterophyes heterophyes e Haplorchis pumilio) no tecido muscular; e nematoides (larvas de Capillaria sp.) no trato digestivo. As características morfológicas das metacercárias dos trematódeos de peixes e dos adultos experimentalmente obtidos são descritas. Esse é o primeiro relato desses parasitas em peixes da Arábia Saudita. Além desses, Myripristis murdjan apresentou alta prevalência de infecção por Capillaria sp. (22,7%), enquanto Haplorchis pumilio foi a espécie de metacercárias dominante (7,9%). Embora o número de casos documentados continue a aumentar, o risco global de infecção humana é pequeno. A exploração crescente do ambiente marinho pelos seres humanos e a tendência de redução do processo de cozimento no preparo de alimentos oriundos do mar aumentam as chances de infecção por esses parasitas. Os resultados deste estudo também indicam que certos sistemas de produção de pescados estão em risco de apresentar parasitas zoonóticos, e que o seu controle trará benefícios na compreensão destes fatores de risco.

RESUMEN

Coprological examination of 15 Indian peacocks, Pavo cristatus, revealed the presence of a coccidium species of the genus Eimeria, which apparently represents a previously undescribed species. Sporulation is exogenous and fully developed oocysts of Eimeria pavoaegyptica sp. nov. are ellipsoidal, with a dimension of 15 (13-16) × 12 (10-12.9) μm and with a shape index of 1.25 (1-1.3). The sporulated oocysts have no micropyle but enclose one large rectangular-shaped polar granule and an oocyst residuum. The oocysts have a distinct two-layered wall, which is ~1.7 μm thick. The outer layer has a smooth texture; it fills ~¾ of the total thickness and appears bicolored. The sporocysts are boat-shaped, of about 10 (9-11) × 4 (4-4.7) μm; their average shape-index is 2.5 μm with a small pointed Stieda body and a smooth, thin single-layered wall. No substieda body is detected. The sporocysts contain numerous, nearly uniform granular residua. The sporozoites are banana-shaped, 6 × 3 μm and each has two different-sized refractile bodies.

RESUMEN

OBJECTIVE: This random retrospective cross-sectional study was done to determine the incidence of uterine malformation in 4 groups of women desiring to conceive during their reproductive years, all of them living in La Crete, a community in Northern Alberta, Canada, with endogamous marriage practices in a 500 year old restricted gene pool. METHODS: During 2003-2006, eight hundred women, suspected of having uterine malformation, were scanned using 2-D abdominal and transvaginal sonography (TVS). A sub-group of 156 patients was identified with suspected uterine malformations and referred for further diagnostic investigation, including MRI, 3-D sonography, hysterosalpingography, hysteroscopy and laparoscopy. This group included 30 women without previous pregnancies (Group 1), 31 women with previous pregnancies and live births (fertile) (Group 2), 40 women with live births and more than 2 miscarriages (Group 3) and 55 women with recurrent miscarriages (infertile) (Group 4). RESULTS: The overall frequency of uterine malformations was recorded at 19.5% in La Crete women. Ninety five women with recurrent or some miscarriages had more uterine malformation than the other groups. The incidence in Groups 3 and 4 (infertile) was 60.8% and 39.2% in the fertile Groups 1 and 2. The p <0.01 was significant at 95% confidence interval. CONCLUSION: This study has provided new insights into the increasing number of uterine malformations in the population of La Crete. It was 19.5%, 5.5 times higher than that of the general population of (0.1% to 3.5%). This might indicate an increase in uterine malformations among women in a restricted gene pool community. A combination of TVS, hysterosalpingography, 3-D sonography and MRI are necessary for the precise classification of uterine malformations. Uterine malformations are not rare, but may be increasingly related to consanguinity. The finding of uterine malformation is more frequent in patients with recurrent miscarriages, especially women with septated, unicornuate, or didelphys uteri.
