Delayed neuropathy after organophosphorus insecticide (Dipterex) poisoning: a clinical, electrophysiological and nerve biopsy study.

Clinical, electrophysiological and histological findings in four patients accidentally poisoned with the organophosphorus insecticide Dipterex are reported. Three to five weeks after insecticide ingestion signs of a distal sensorimotor (preponderantly motor) neuropathy occurred. The patients complained of paraesthesia in the lower limbs, and two of them of very disagreeable pricking sensation in the soles of the feet, responsive to carbamazepine. They showed distal weakness mainly of the legs, footdrop , difficult gait and muscle hypotonia. Ankle jerk was abolished while other tendon reflexes persisted. Two months or even later after poisoning, knee jerks in all the patients were very brisk and more and less accompanied by other pyramidal signs (patellar clonus, abolishment of abdominal cutaneous reflexes, Babinski's sign). Clinical, electrophysiological and nerve biopsy data revealed a "dying-back" neuropathy in our patients. Distal muscle fatigue was confirmed by failure of neuromuscular transmission on repetitive nerve stimulation.

Sensorimotor neuropathy in a patient with Marinesco-Sjögren syndrome.

A case of Marinesco-Sjögren syndrome, displaying the characteristic signs (ataxia, congenital cataract and mental retardation) is presented. Electrophysiological examination pointed to the presence of a sensorimotor peripheral neuropathy with an underlying mixed process of segmental demyelination and axonal degeneration (probably secondary). The sural nerve and gastrocnemius biopsy confirmed these data, showing that in this case the segmental demyelination process was accompanied by axonal degeneration.

Nucleosides and nucleotides. 121. Synthesis of oligonucleotides carrying linker groups at the 1'-position of sugar residues.

Novel 2'-deoxyuridine analogues carrying aminoalkyl linkers at the 1'-position of the sugar residues were synthesized and incorporated into oligonucleotides, then intercalating groups such as an anthraquinone derivative and a pyrene derivative were attached to the amino groups. Duplexes consisting of the oligonucleotides carrying the linker groups and a complementary ribonucleotide were more stable than an unmodified parent duplex, but the duplexes consisting of the oligonucleotides and a complementary deoxyribonucleotide were less stable. The oligonucleotides carrying the linker groups were more resistant to nuclease P1 and venom phosphodiesterase than an unmodified oligonucleotide. Furthermore, a duplex formed by the oligonucleotide analogue and the complementary ribonucleotide was a substrate for ribonuclease H.

Promoting the advancement of minority women faculty in academic medicine: the National Centers of Excellence in Women's Health.

Minority physicians provide care in a manner that promotes patient satisfaction and meets the needs of an increasingly diverse U.S. population. In addition, minority medical school faculty bring diverse perspectives to research and teach cross-cultural care. However, men and women of color remain underrepresented among medical school faculty, particularly in the higher ranks. National data show that although the numbers of women in medicine have increased, minority representation remains essentially static. Studying minority women faculty as a group may help to improve our understanding of barriers to diversification. Six National Centers of Excellence in Women's Health used a variety of approaches in addressing the needs of this group. Recommendations for other academic institutions include development of key diversity indicators with national benchmarks, creation of guidelines for mentoring and faculty development programs, and support for career development opportunities.

Using women's health research to develop women leaders in academic health sciences: the National Centers of Excellence in Women's Health.

While the number of women entering U.S. medical schools has risen substantially in the past 25 years, the number of women in leadership positions in academic medicine is disproportionately small. The traditional pathway to academic leadership is through research. Women's health research is an ideal venue to fill the pipeline with talented women physicians and scientists who may become academic leaders in positions where they can promote positive change in women's health as well as mentor other women. The Office on Women's Health (OWH) in the U.S. Department of Health and Human Services has contracted with 18 academic medical centers to develop National Centers of Excellence in Women's Health. Emphasizing the integral link between women's health and women leaders, each of the Centers of Excellence must develop a leadership plan for women in academic medicine as part of the contract requirements. This paper describes the training programs in women's health research that have developed at five of the academic medical centers: the University of Wisconsin, Magee Women's Hospital, the University of Maryland, Medical College of Pennsylvania Hahnemann University, and the University of Illinois at Chicago. We discuss some of the challenges faced for both initiation and future viability of these programs as well as criteria by which these programs will be evaluated for success.

A study on awareness of AIDS among school students and teachers of higher secondary schools in north Calcutta.

Higher Secondary School students and their teachers were studied to assess the knowledge about AIDS and attitude towards AIDS patients. Only 13.5% senior school students and 16.2% teachers had clear knowledge regarding AIDS--its general aspects, transmission and prevention. Girls had higher and clear knowledge than boys. 45.8% of girls, 38.8% of boys students and 20.3% of teachers had positive attitudes towards nursing an AIDS case. It is suggested that schools have to device ways to open up more effective communication with students in relation to education on sex and AIDS. Training on AIDS should be emphasized on school teachers who on their turn can teach the students in a correct way about AIDS.
