Latex agglutination test: an adjunct to the laboratory diagnosis of pyogenic bacterial meningitis.

Gram stain, culture and latex agglutination test (LAT) of cerebrospinal fluid were performed in 50 patients clinically diagnosed as suffering from pyogenic bacterial meningitis. Using all the three techniques, an aetiological diagnosis was made in 27 (54%). Neisseria meningitidis, Streptococcus pneumoniae and H. influenzae were the infecting organisms in 21 cases (44%). There were 12 additional cases in which LAT was the only clue to the diagnosis as compared to conventional techniques. Propionibacterium acnes was isolated from one case of anaerobic meningitis. It is concluded that LAT is an adjunct to conventional techniques in the diagnosis of pyogenic bacterial meningitis, where the latter tests fail.

Mycoplasma infections of the human respiratory tract.

The knowledge on the role of M. pneumoniae in human respiratory tract infections especially in infants and children has advanced in the past two decades. The understanding of its incidence, clinical presentations, pathology & pathogenesis, laboratory diagnosis, complications and late sequelae, treatment, prevention and epidemiological aspects place it as an important aetiological agent in the pediatric patients. It should be considered in the differential diagnosis of all pneumonias. Further studies are needed to solve many observations on the role of mycoplasma in diseases of man.

Comparative bioequivalence study of different brands of acetyl salicylic acid in human volunteers.

A double blind cross over randomized study was conducted in 7 normal healthy volunteers. Single dose (700 mg) of buffered aspirin or aspirin with calcium carbonate or aspirin with caffeine was administered orally, at least 3 days apart. Blood samples were drawn at different time intervals after administration of drug for estimation of salicylate levels. The values of different pharmacokinetic parameters (AUC0-infinity, Cmax and tmax) did not show any significant difference, suggesting that these three brands of aspirin are biologically equivalent.

Chlamydia trachomatis infection among pregnant women: prevalence and prenatal importance.

BACKGROUND: Chlamydia trachomatis infection in pregnant women is suspected to result in low birth-weight and premature infants. We conducted studies to ascertain the prevalence of this infection among pregnant women in our setting and whether its presence is a risk factor for low birth-weight or prematurity. METHODS: In the first study, 94 pregnant women between 26 and 30 weeks of gestation were screened for infection with Chlamydia trachomatis. The second investigated a cohort of 172 pregnant women presenting in spontaneous labour. The infection status was related to perinatal outcome in terms of birth-weight and gestation. In both the studies, Chlamydia trachomatis infection was diagnosed using the Chlamydiazyme test performed on endocervical swabs. RESULTS: The prevalence of Chlamydia trachomatis infection in mid-pregnancy and at labour was 17% (16/94) and 18.6% (32/172), respectively. Women with infection were relatively older than those without it [mean (SD) age: 26.6 (4.5) years v. 24.8 (3.6) years, p = 0.01]. The mean (SD) birth-weight [2869 (611) g v. 2814 (496) g], gestation [38.5 (2.6) weeks v. 38.3 (2.0) weeks], and incidence of low birth-weight [18.7% v. 20.7%] as well as prematurity [9.4% v. 10.7%] were similar among neonates born to women with or without infection. Neonates born to infected mothers experienced purulent conjunctivitis more frequently than those born to non-infected mothers [12.5% v. 2.8%, p = 0.04]. CONCLUSION: Chlamydia trachomatis is a relatively common infection in pregnant women. However, it was not associated with either low birth-weight or prematurity.

Sub-polar lepromatous leprosy presenting as urticarial wheals: a case report.

A 40-year male lepromatous leprosy patient presented with four, slightly erythematous patches, with multiple urticaria-like wheals, distributed over the body symmetrically and with thickened right ulnar and right common peroneal nerves. He was previously diagnosed as a case of chronic idiopathic urticaria. Slit skin smear from the patches and urticarial wheals showed a BI of 3+ and skin biopsy showed some features of borderline lepromatous leprosy (BL).

Necrotic erythema nodosum leprosum.

A 30 year-old farmer presented himself with mild degree fever, joint pain and multiple ulcers of 15 days' duration. Ulcers were multiple, well-defined, irregular in shape with necrotic base and elevated, sloppy margins over anus, forearms, wrists, buttocks, lower half of thighs and shins. A few of the ulcers were covered with black-coloured scab. They were tender and with serosanguinous discharge. Black atrophic scars and ill-defined, irregular, brown black-pigmented macules of various sizes were present over thighs and legs. Excision biopsy of the ulcer showed features of erythema nodosum leprosum. The patient was treated with systemic corticosteroids.
