Valor de la escala ASPECTS de circulación posterior y del índice puente-mesencéfalo en imágenes de TC sin contraste y angiografía por TC en pacientes con oclusiones de la arteria basilar recanalizados tras trombectomía mecánica

Purpose

Endovascular treatment with mechanical thrombectomy devices demonstrated high recanalization rates but functional outcome did not correlate with high rates of recanalization obtained. Patient selection prior to the endovascular treatment is very important in the final outcome of the patient. The primary aim of our study was to evaluate the prognostic value of posterior circulation Alberta Stroke Program Early CT Score (pc-ASPECTS) and Pons-Midbrain Index (PMI) scores in patients with Basilar Artery Occlusion (BAO) treated with successful angiographic recanalization after mechanical thrombectomy.

Mumps and rubella morbidity

This paper studies all cases affected by 5 parotiditis from January to September 1986 (1767 cases) and 1987 (124 cases), as well as all patients with rubella reported in the same period in 1986 (584 cases) and 1987 (5 cases) in the province of Pinar del Río. The rise in the incidence of the two diseases with an annual basis per 100,000 population during 1986 in the different municipalities is emphasized. The overtly downward trend of these two diseases in 1987 after the administration of the triple viral vaccine--93% for mumps and 99.15% for rubella--is discussed. It was found that these two diseases affected more often school children (5-14 years). It was found that these two diseases are not frequent under the first year of life (76.4 and 120.1 cases per 100,000 population respectively). The percentage of vaccine effectiveness was documented--97.4% for parotiditis and 100% for rubella.     

Identity formation in adolescence: Case study of gender identity disorder and treatment through an intermediate-care day hospital

A review of the literature on gender identity disorders is integrated with a case study presentation of a psychiatrically disturbed nineteen-year-old transvestite youth. Accommodations and interventions made both with this patient and in the day care program for psychiatrically disturbed youths that allowed him to live at home and be maintained despite severe pathology are discussed. Amaro Reyes, M.D. was formerly an attending Psychiatrist in the Community Division of Bronx Children's Psychiatric Center     

Spontaneous pyomyositis and AIDS: An infrequent association

Summary Pyomyositis is an acute bacterial infection of striated muscle. It is common in the tropics, but rarely reported in temperate climates. We present two cases in patients with the acquired immune deficiency syndrome (AIDS), one an active homosexual, and one an intravenous drug user. A brief review of the clinical findings and diagnostic procedures is included. We conclude that pyomyositis should be included in the list of locations of pyogenic infections that can occur in AIDS patients.

Spontane Pyomyositis und AIDS: ein seltenes Zusammentreffen

Zusammenfassung Die Pyomyositis ist eine akute bakterielle Infektion der quergestreiften Muskulatur. Im Gegensatz zu den Tropen, wo sie häufig auftritt, wird die Pyomyositis in gemäßigten Klimazonen nur selten beobachtet. Wir stellen zwei Patienten mit Pyomyositis und AIDS vor: der eine Patient ist Homosexueller, der andere intravenös drogenabhängig. Klinische Befunde und diagnostisches Vorgehen werden kurz dargestellt. Nach unserer Meinung sollte die Pyomyositis in die Liste pyogener Infektionslokalisationen bei AIDS-Patienten eingereiht werden.

     

Supravalvular aortic stenosis and coronary aneurysm]

A 32-year old woman, with endocarditis caused by Streptococcus mitis, and systolic murmur is presented. The Doppler examination was found a systolic gradient of 150 mmHg. Aortography showed a multiple membranous supravalvular aortic stenosis, with aneurysmal dilatation of the left main coronary artery and circumflex artery, associated with bicuspid aortic valve and mild aortic insufficiency. The patient died suddenly by cardiac arrest in stand by to cardiac surgery. Anatomic comprobation was not possible. The coronary artery anomalies associated with the supravalvular aortic stenosis syndrome are reviewed.     

Distribution of spermatogenesis in the testicles of azoospermic men: the presence or absence of spermatids in the testes of men with germinal failure [published erratum appears in Hum Reprod 1998 Mar;13(3):780]

The aim of the study was to determine whether a prior diagnostic testicle biopsy can predict success or failure of testicular sperm extraction (TESE) with intracytoplasmic sperm injection (ICSI) in patients with non-obstructive azoospermia caused by testicular failure, and what is the minimum threshold of sperm production in the testis which must be surpassed for spermatozoa to reach the ejaculate. Forty- five patients with non-obstructive azoospermia caused by testicular failure underwent diagnostic testicle biopsy prior to a planned future TESE-ICSI procedure. The diagnostic testicle biopsy was analysed quantitatively, and correlated with the quantitative findings of spermatogenesis in patients with normal spermatogenesis, as well as with the results of subsequent attempts at TESE-ICSI. Men with non- obstructive azoospermia caused by germinal failure had a mean of 0-6 mature spermatids/seminiferous tubule seen on a diagnostic testicle biopsy, compared to 17-35 mature spermatids/tubule in men with normal spermatogenesis and obstructive azoospermia. These findings were the same for all types of testicular failure whether Sertoli cell only, maturation arrest, cryptorchidism, or post-chemotherapy azoospermia. Twenty-two of 26 men with mature spermatids found in the prior testis biopsy had successful retrieval of spermatozoa for ICSI, 12 of their partners became pregnant, and are either ongoing or delivered. The study suggests that 4-6 mature spermatids/tubule must be present in the testis biopsy for any spermatozoa to reach the ejaculate. More than half of azoospermic patients with germinal failure have minute foci of spermatogenesis which are insufficient to produce spermatozoa in the ejaculate. Prior diagnostic testicle biopsy analysed quantitatively (for the presence of mature spermatids) can predict subsequent success or failure with TESE-ICSI. Incomplete testicular failure may involve a sparse multi-focal distribution of spermatogenesis throughout the entire testicle, rather than a regional distribution. Therefore, it is possible that massive testicular sampling from many different regions of the testes may not be necessary for successful TESE-ICSI.      

Adhesion inhibitory activity of β-lactoglobulin isolated from infant formulae

β-Lactoglobulin was isolated from infant formulae that were ultra high temperature (UHT) -treated, sterilized or spray-dried. The effect of the isolated β-lactoglobulin on SfaII-fimbriae-mediated adhesion of Escherichia coli to human ileostomy glycoproteins was studied in vitro. β-Lactoglobulin isolated from sterilized formulae was found to perform significantly less well than preparations from spray-dried formulae (p = 0:05). Great heterogeneity was observed in the adhesion inhibitory capacity of β-lactoglobulin isolated from UHT-treated formulae. Therefore, no significant difference was observed between UHT-treated and sterilized formulae or spray-dried formulae (p < 0:10). It can be hypothesized that β-lactoglobulin from spray-dried and some UHT-treated infant formulae may affect the colonization of mucous membranes by E. coli strains causing neonatal septicaemia and meningitis.
