A total of 651 cases of leprosy were hospitalised from Jan 1987 to Dec 1992. Each patient underwent haemogram, total and differential white cell count, urinalysis, liver function tests, skin slit smear for AFB and skin biopsy. Nerve conduction studies, electomyographic studies and nerve/nerve sheath biopsies were undertaken as and when indicated. These patients were managed with multidrug therapy. Paucibacillary (PB) leprosy accounted for 476 (73.1%) cases which comprised of indeterminate leprosy 90 (13.8%), tuberculoid leprosy 14 (2.2%), borderline tuberculoid leprosy 310 (47.6%) and neuritic leprosy 62 (9.5%). The remaining 175 patients (26.9%) were multibacillary (MB) which included borderline leprosy 9 (1.4%), borderline lepromatous leprosy 129 (19.8%) and lepromatous leprosy 37 (5.7%) patients. There were total 153 patients in 1987. This number declined to 44 in 1992. PB declined from 113 in 1987 to 39 in 1992 and MB cases from 40 to 5.KEY WORDS: Leprosy 相似文献

The relationship between follicular fluid aspirate volume and oocyte maturity in in-vitro fertilization cycles 总被引:1,自引:5,他引:1

As a consequence of multiple follicular growth during ovarian stimulation
for in-vitro fertilization (IVF), follicles of varying sizes often yield
oocytes that vary in maturity and morphology of the oocyte-cumulus-corona
complex. The objective of this prospective study was to explore the
relationship between follicular fluid aspirate volume and the oocyte's
developmental potential in an IVF treatment cycle. In total 9933 follicles
were studied from 400 patients who underwent 535 consecutive IVF treatment
cycles at St James's University Hospital, Leeds, UK, between February 1995
and February 1996. The volume of each individual follicle aspirated was
recorded and related to the probability of obtaining an oocyte, its
fertilizing capacity, the cleavage rate and the quality of embryos derived.
We found no statistically significant difference in oocyte recovery rates
between follicles with an aspirate volume < or = 1 ml and follicles with
a volume > 1 ml. Although oocytes obtained from follicles with an
aspirate volume > or = 1 ml showed a significantly lower fertilization
rate, they went on to cleave at the same rate as oocytes obtained from
larger follicles and resulted in embryos of comparable quality.
Furthermore, there was no statistically significant difference in the
implantation, clinical pregnancy or live birth rates per cycle between
embryos derived from follicles with an aspirate volume < or = 1 ml and
those derived from follicles with an aspirate volume > 1 ml. We conclude
that follicular size and the oocyte's developmental potential in the
stimulated ovary are not closely related and can be independent. This is in
contrast to the Graafian follicle and the pre-ovulatory oocyte in the
natural cycle.

Use of 16S rRNA gene sequencing for rapid identification and differentiation of Burkholderia pseudomallei and B. mallei 下载免费PDF全文

Burkholderia pseudomallei and B. mallei, the causative agents of melioidosis and glanders, respectively, are designated category B biothreat agents. Current methods for identifying these organisms rely on their phenotypic characteristics and an extensive set of biochemical reactions. We evaluated the use of 16S rRNA gene sequencing to rapidly identify these two species and differentiate them from each other as well as from closely related species and genera such as Pandoraea spp., Ralstonia spp., Burkholderia gladioli, Burkholderia cepacia, Burkholderia thailandensis, and Pseudomonas aeruginosa. We sequenced the 1.5-kb 16S rRNA gene of 56 B. pseudomallei and 23 B. mallei isolates selected to represent a wide range of temporal, geographic, and origin diversity. Among all 79 isolates, a total of 11 16S types were found based on eight positions of difference. Nine 16S types were identified in B. pseudomallei isolates based on six positions of difference, with differences ranging from 0.5 to 1.5 bp. Twenty-two of 23 B. mallei isolates showed 16S rRNA gene sequence identity and were designated 16S type 10, whereas the remaining isolate was designated type 11. This report provides a basis for rapidly identifying and differentiating B. pseudomallei and B. mallei by molecular methods. 相似文献

The diagnosis and management of childhood tuberculosis (TB) are major challenges in countries such as Malawi with high incidence of TB and human immunodeficiency virus (HIV) infection. Diagnosis of TB in children often relies only on clinical features but clinical overlap with the presentation of HIV and other HIV-related lung disease is common. The tuberculin skin test (TST), the standard marker of M. tuberculosis infection in immune competent children, has poor sensitivity in HIV-infected children and is not usually available in Malawi. HIV test should be routine in children with suspected TB as it improves clinical management. HIV-infected children are at increased risk of developing active disease following TB exposure which justifies the use of isoniazid preventive therapy (IPT) once active disease has been excluded but this is difficult to implement and appropriate duration of IPT is unknown. HIV-infected children with active TB experience higher mortality and relapse rates on standard TB treatment compared to HIV-uninfected children, highlighting the need for further research to define optimal treatment regimens. HIV-infected children should also receive appropriate supportive care including cotrimoxazole prophylaxis and anti-retroviral treatment (ART) if indicated. There are concerns about concurrent use of some anti-TB drugs such as rifampicin with some ARTs. 相似文献

To evaluate the reliability of phosphorus-31 magnetic resonance (MR) spectroscopy in the assessment of acute testicular ischemia, vascular integrity, and spermatogenesis, the authors studied in vivo canine and primate testicles grouped as follows: group 1 testes (n = 8), in situ canine controls; group 2 (n = 11), canine testes subjected to warm ischemia; group 3, canine (n = 4) and primate (n = 4) testicles from hormone-treated animals. Group 1 control testicles showed high monophosphoester (MP) levels; low levels of inorganic phosphate (Pi), phosphodiester (PD), and phosphocreatine; and high levels of adenosine triphosphate (ATP). Group 2 testes revealed a time-dependent decay of MP/Pi ratios (from 2.1 to 0.70). Regeneration of ATP was noted in the acute reperfusion period. After 6 weeks of pituitary gonadotropin suppression, group 3 testes showed a significant decrease (P less than .05) in MP/PD ratios from a control level of 2.6 +/- 0.3 and a decrease in the MP/beta-ATP ratio from 2.4 +/- 0.1 to 1.8 +/- 0.3. P-31 MR spectroscopy appears to be a potential method for noninvasively assessing testicular ischemic injury and the metabolic integrity of spermatogenesis. 相似文献

SUMMARY The aim of this review is to sort out from the huge amount of facts related to digoxin in the literature those pertinent to current clinical practice. Seven aspects of digoxin are discussed: its mechanism of action, therapeutic controversy, clinical efficacy, avoidance of toxicity, manifestations of toxicity, indications, and its use in coronary artery disease 相似文献
