Knowledge and practices regarding toxoplasmosis in housewives: A cross sectional study in a northern Mexican city.

We aimed to determine the knowledge and practices regarding toxoplasmosis among housewives in the northern Mexican city of Durango. One hundred eighty-five women (mean age: 41.27 ± 12.40 years old) with an occupation of housewife were studied. A self-administered questionnaire was used. This tool included items about the parasite Toxoplasma gondii, its transmission routes, general clinical, diagnostic, and treatment aspects of toxoplasmosis, and practices to avoid infection. A minority (<10%) of women knew about the parasite, the disease, how the transmission occurs, the clinical manifestations, how an infection is diagnosed, the treatment, and how to avoid toxoplasmosis. Some women knew that cats can transmit T. gondii infection (20%), and that the parasite can be found in cat feces (20.5%). Only 7.6% of women knew that infection with T. gondii can be transmitted by consumption of contaminated food or water. Only 1.1% of women knew about the prevalence of T. gondii infection. Some (4.9%) women used to taste raw meat while cooking, and 7.6% used to undercook meat. In addition, 20% of women used to eat raw dried meat, and 13.5% consumed untreated water. Less than 90% of women always washed their hands before cooking, and washed fruits or vegetables. The majority (75.1%) of women never wore gloves when handling raw meat. About one quarter (27.6%) of women always froze meat. And 16.2% of women cleaned cat feces. This is the first study regarding knowledge and practices about toxoplasmosis in housewives. Poor knowledge regarding T. gondii infection, toxoplasmosis, and practices to avoid infection among the housewives studied was found. High risk practices for infection were identified. Strategies to improve toxoplasmosis-related knowledge and practices to avoid T. gondii infection and its sequelae in housewives are highly needed.

Whole-Genome Sequences of Salmonella enterica Serovar I 4,[5],12:i:- Isolates from Swine.

Salmonella enterica (non-Typhi) is one of the top five pathogens causing enteric infections worldwide. Draft whole-genome sequences of multidrug-resistant (MDR) Salmonella enterica serovar I 4,[5],12:i:- isolates from swine tissue samples collected at slaughter were evaluated for antimicrobial resistance genotypes. In recent years, Salmonella enterica serovar I 4,[5],12:i:- has increased in prevalence in humans and animals and has been linked to the consumption of contaminated pork.

Contribution of early SPECT/CT to 99mTc-MIBI double phase scintigraphy in primary hyperparathyroidism: Diagnostic value and correlation between uptake and biological parameters / Aportación del SPECT/TC precoz a la gammagrafía de doble fase con 99mTc-MIBI en pacientes con hiperparatiroidismo primario: valor diagnóstico y correlación de la captación con parámetros biológicos

Aim. To evaluate the value of 99mTc-MIBI double-phase scintigraphy (DPS) and early SPECT/CT in the pre-surgical assessment of patients with primary hyperparathyroidism (PHPT). Also, to calculate the correlation between uptake and some biological parameters. Material and methods. Forty patients with PHPT were included: 37 solitary adenomas, 1 hyperplasia, and 2 double adenomas. Fifteen patients had ectopic glands. DPS and early SPECT/CT were acquired in all patients. Ultrasound was performed in 31/40. All patients underwent surgery, intra-operative iPTH measurements, and histopathological examinations. Qualitative DPS uptake was assessed and correlated to pre-surgical calcium, iPTH levels, gland weight, and maximum diameter. Results. In the planar study, there were 23 positive cases, 8 doubtful, and 9 negatives. With the SPECT/CT, 8/9 negatives cases were located. All doubtful cases were confirmed as positives. Gland location improved in 16 cases (12 ectopic). DPS+SPECT/CT failed to detect a solitary adenoma and at least one gland in three cases of multiglandular disease (MGD). The sensitivity by patient was: DPS 72.5%, DPS+SPECT/CT 90%, and ultrasound 42%. Ultrasound and scintigraphy (DPS+SPECT/CT) were concordant in 16/31 patients. For the rest of them, scintigraphy proved correct in 14/15, and both techniques failed in one case. There was a significant correlation between level of uptake and iPTH level, gland weight, and maximum diameter. Conclusion. Early SPECT/CT improves sensitivity and the locating of parathyroid pathological glands and increases diagnostic confidence. iPTH level, glandular size, and weight are related to the qualitative assessment of 99mTc-MIBI uptake in early DPS (AU)

Objetivo. Evaluar la gammagrafía de doble fase con 99mTc-MIBI (GDF) y el SPECT/TC precoz, en la valoración prequirúrgica del hiperparatiroidismo primario (HPTP), calculando la correlación entre grado de captación y algunos parámetros biológicos. Material y métodos. Se incluyeron 40 pacientes: 37 adenomas solitarios, dos adenomas dobles, una hiperplasia. Quince tenían glándulas ectópicas. En 40 pacientes se realizaron GDF y SPECT/TC; en 31/40, ecografía. Todos los pacientes fueron intervenidos, realizando determinación de PTHi intraoperatoria y examen histopatológico. Se evaluó cualitativamente la captación en la GDF, correlacionándose con calcio y PTHi prequirúrgicos, peso y diámetro máximo glandulares. Resultados. En el estudio planar se obtuvieron 23 casos positivos, 8 dudosos, y 9 negativos. Con SPECT/TC se localizaron 8/9 de los negativos. Todos los dudosos se confirmaron como positivos. La localización glandular mejoró en 16 casos (12 ectópicos). La GDF+SPECT/TC fallaron en la detección de un adenoma solitario y en la visualización de alguna de las glándulas en tres casos de enfermedad multiglandular (EMG). La sensibilidad por pacientes fue: GDF 72,5%, GDF+SPECT/TC 90%, ecografía 42%. Ecografía y gammagrafía (GDF+SPECT/TC) concordaron en 16/31 pacientes. De los no concordantes, la gammagrafía acertó en 14/15 y ambas técnicas fallaron en uno. Hubo correlación significativa entre captación y PTHi, peso y diámetro máximo glandulares. Conclusion. El SPECT/TC precoz mejora la sensibilidad y la localización de las paratiroides patológicas y aumenta la confianza diagnóstica. PTHi, tamaño y peso glandulares se correlacionan con la valoración cualitativa de la captación precoz de 99mTc-MIBI en la GDF (AU)

The value of early SPECT/CT and hand-held γ-camera in radio-guided surgery: a case of a hard-to-locate parathyroid adenoma.

A patient with primary hyperparathyroidism underwent radio-guided surgery by means of a γ-probe and a hand-held γ-camera. Before surgery, a parathyroid double-phase planar scintigraphy and an early SPECT/CT with 99mTc-MIBI were performed and suggested an ectopic parathyroid adenoma with early washout. The hand-held γ-camera was very useful for the localization of a parathyroid adenoma, which could not be found with the probe probably due to its faint uptake and to a high blood pool activity because it was localized next to the great vessels. Besides, it demonstrated the complete extirpation of the parathyroid tissue.

[Thoracopleuromyoplasty as definitive cure for chronic pleural empyemas, after preparation by open thoracostomy]. / La thoracopleuromyoplastie comme correction définitive des empyèmes pleuraux chroniques, après préparation avec thoracostomie ouverte.

Between 1979 and 1986, 30 patients with chronic pleural empyema (19 with pyothorax secondary to tuberculosis and 11 with pleural empyema following pulmonary resection) underwent two-stage treatment. The first stage consisted of open thoracostomy and was followed, 2 to 7 months later, by thoracopleuromyoplasty with latissimus dorsi, serratus anterior and pectoralis major muscles either alone or in combination. There was no operative mortality in this series of 30 operated patients. Definitive obliteraion of the pleural cavity and closure of the bronchial fistulae were obtained in 26 of the 30 patients. Partial necrosis of the muscle graft in the other 4 patients required further open drainage and an additional myoplasty. The long-term functional results in the cases of post-resection empyema were compatible with the restriction created by the pulmonary resection and, in the cases of empyema with a residual lung, with the restriction of the volume and perfusion of pulmonary parenchyma.
