Abstract
Although the incidence of new end-stage renal disease (ESRD) patients in Pakistan is estimated at 100 patients per million (ppm), the prevalence of those alive on renal replacement therapy (RRT) is around 40 ppm, reflecting the severe shortage of facilities. A national program was launched in 1998 to provide free RRT, but the funds were extremely limited, leading to the flourishing of suboptimal treatment in private dialysis and transplant centers. The Sindh Institute of Urology and Transplantation (SIUT), started as a small unit in 1975, took the lead in recruiting nongovernmental funds for RRT. Through the devotion of several groups, it was possible to raise funds from individuals, pharmaceutical firms, and other organizations, which permitted the development of SIUT into an independent, large, and fully equipped institution that provides free RRT including dialysis and transplantation to many thousands of patients. This prompted the government to increase its contributions to encourage SIUT to pursue its unique path.

Abstract
A 22-y-old male developed fever, arthralgias and skin rash 2 d after tonsillectomy. Blood culture grew Neisseria meningitidis. He responded well to antibiotics. Only 1 other case of meningococcal sepsis following adenotonsillectomy has previously been reported. These cases suggest a temporal association of meningococcemia with tonsillectomy.

Abstract
SETTING Sputum samples were collected from suspected tuberculosis patients attending out-patient clinics at the Ojha Institute of Chest Diseases, Karachi, Pakistan. OBJECTIVE To evaluate the performance of the FASTPlaqueTB assay for rapid diagnosis of pulmonary tuberculosis. DESIGN A comparative study of 584 sputum samples using acid-fast smear microscopy, Lowenstein-Jensen culture and FASTPlaqueTB. RESULTS A total of 514 samples yielded complete results. Seventy specimens were lost to analysis due to the overgrowth of contaminants. The addition of antimicrobials inhibited growth of gram-positive contaminants, and reduced the overall contamination rate from 18.2% to 7.2%. Mycobacterium tuberculosis was isolated from 175 smear-positive and 70 smear-negative specimens. FASTPlaqueTB detected M. tuberculosis in 81.6% of specimens, with a specificity of 97.7%. The sensitivity and specificity of the assay for smear-positive specimens were respectively 87.4% and 88.2%. For smear-negative specimens, the sensitivity of the assay was 67.1% and the specificity was 98.4%. The combined sensitivity of smear and FASTPlaqueTB for M. tuberculosis was 90%. Test results were available in 48 hours. CONCLUSION FASTPlaqueTB is a sensitive and specific test for rapid diagnosis of pulmonary tuberculosis in high prevalence areas. The test is sensitive enough to confirm a large number of clinically suspected smear-negative cases and improve case finding.

Abstract
Filariasis is a major health problem in South Asia, particularly India, Sri Lanka and Bangladesh. Pakistan was presumed to be not affected. We report for the first time confirmed cases of tropical pulmonary eosinophilia (TPE) in indigenous patients as a result of infection with Wuchereria bancrofti. Following clinical examination, total leukocyte and eosinophil counts were recorded. Parasitological examinations included blood for microfilariae and stool and urine for eggs of intestinal parasites. Total immunoglobulin (Ig) E and specific antifilarial IgG were measured. Suspected cases of TPE were treated with diethylcarbamazine, 6 mg/kg for four weeks and were followed up to 2 and 4 weeks after treatment. Four persons fulfilled the criteria for TPE. Their response to treatment was marked with clinical improvement, reduction in eosinophil count and reduced titers of specific antifilarial antibodies. Two persons had W. bancrofti antigen in their sera confirmed by filariasis antigen detection test. Tropical pulmonary eosinophilia due to Wuchereria. bancrofti, although rare, is present in Pakistan.

Abstract
Apolipoprotein H (apoH, protein; APOH, gene) binds to negatively charged phospholipids, which triggers the production of a subset of autoantibodies against phospholipid in patients with autoimmune diseases. We have demonstrated that two naturally occurring missense mutations in the fifth domain of apoH, Trp316Ser and Cys306Gly, disrupt the binding of native apoH to phosphatidylserine [Sanghera, D. K., Wagenknecht, D. R., McIntyre, J. A. & Kamboh, M. I. (1997) Hum. Mol. Genet. 6, 311-316]. To confirm whether these are functional mutations, we mutagenized APOH cDNAs and transiently expressed them in COS-1 cells. The cardiolipin ELISA of wild-type and mutant recombinant apoH confirmed that the Gly306 and Ser316 mutations are responsible for abolishing the binding of recombinant apoH to cardiolipin. These mutations, however, had no effect on the levels of expression or secretion of recombinant apoH in transfected COS-1 cells. While the Cys306Gly mutation disrupts a disulfide bond between Cys306 and Cys281, which appears to be critical for clustering positively charged amino acids, the Trp316Ser mutation affects the integrity of an evolutionarily conserved hydrophobic sequence at position 313-316 (Leu-Ala-Phe-Trp), which is hypothesized to interact with anionic phospholipid. To test this hypothesis, we exchanged the remaining three hydrophobic amino acids with neutral amino acids by site-directed mutagenesis (Leu313Gly, Ala314Ser and Phe315Ser). Binding of the Leu313Gly and Phe315Ser mutants to cardiolipin was significantly reduced to 25% and 13%, respectively, of that of the wild-type. On the other hand, the Ala314Ser mutation showed normal cardiolipin binding. Taken together with our previous findings, these results strongly suggest that the configuration of the fifth domain of apoH, as well as the integrity of the highly conserved hydrophobic amino acids at positions 313-316, is essential for the binding of apoH to anionic phospholipid.

Abstract
BACKGROUND Harterâs Self-Perception Profile for children (SPPC) is a self-reporting inventory for ascertaining childrenâs perception of themselves in various specific domains of their life, as well as their sense of global selfworth. A few studies have examined the psychometric properties of this instrument in the Western setting, but none have investigated this in an Arabic culture. PATIENTS AND METHOD Psychometric properties of the SPPC were examined, using a sample of 100 schoolchildren aged 8 to 16 years in the United Arab Emirates. RESULTS The internal consistency reliability was found to be excellent with Chronbachâs alpha, ranging from 0.86 to 0.92. Significant age and gender differences were found with the internal consistency reliability scores, being higher in children aged 13 to 16 years (0.88 to 0.93) when compared to younger children, especially boys aged 8 to 12 years (0.54 to 0.66), suggesting a need to exercise caution while using this scale in young boys in this culture. Behavioral conduct subscale was found to have the highest reliability score and the strongest correlation to global self-worth (r=0.54) for both younger and older children in our sample. This is in contrast to findings from similar studies carried out on American and Dutch samples, where this subscale was found to have the lowest reliability score and the weakest correlation with oneâs global self-worth. CONCLUSION The findings indicate that the SPPC is a reliable and internally valid instrument for use in the Arab culture.
