1.  Malignant eccrine spiradenoma with carcinomatous and sarcomatous elements. 
Journal of Clinical Pathology  1997;50(10):871-873.
A case of a 60 year old man with malignant eccrine spiradenoma involving the perineum is described. Areas of typical eccrine spiradenoma were admixed with carcinomatous and sarcomatous elements. Immunohistochemical and ultrastructural analysis revealed no evidence of epithelial differentiation in the sarcomatous areas. The tumour qualified for the designation carcinosarcoma arising in eccrine spiradenoma. The clinical course was aggressive with rapid development of nodal and pulmonary metastases.

3.  Unusual traits associated with Robinow syndrome. 
Journal of Medical Genetics  1997;34(9):736-740.
We report on some members of two unrelated families showing the characteristic features of Robinow syndrome. In a consanguineous Kuwaiti family, the index case with Robinow syndrome showed some unusual features including severe IUGR, laxity of ligaments, hyperextensible joints, redundant skin folds, severe normocytic anaemia, repeated infection, increased percentage of total T cells and CD4 positive population, reduced percentage of CD8 positive cells, and EMG abnormality. In a Pakistani family with a high degree of multigenerational consanguinity, a single case with the Robinow phenotype also had congenital heart disease, mainly involving the right side of the heart, with pulmonary stenosis, tricuspid atresia, ASD, VSD, double outlet right ventricle, and right atrial isomerism. This report suggests that the disease profile of Robinow syndrome may be extended to accommodate the unusual traits mentioned above. The association of the Robinow phenotype with congenital heart disease in case 2 of this report is consistent with the previously reported finding that congenital heart disease, particularly involving the right side of the heart, may be a prominent component of Robinow syndrome in a subset of patients.

4.  Evaluation of antibodies reactive with Campylobacter jejuni in Egyptian diarrhea patients. 
Serum and stool samples were collected from 128 individuals: 96 diarrhea patients and 32 apparently healthy controls. Stool specimens were cultured for enteric bacterial pathogens, while sera were screened by enzyme-linked immunosorbent assay for Campylobacter jejuni-reactive antibodies. Of 28 diarrhea patients who demonstrated C. jejuni-reactive antibodies (titers, > 100), 14 were culture positive for this organism. The 32 healthy controls showed significantly lower antibody titers (P < 0.05) with the exception of 10 subjects who were culture positive for C. jejuni and had reactive immunoglobulin M (IgM) (6 subjects) and IgG (7 subjects). IgA was not detected in those 10 individuals (asymptomatic). Avidity was expressed as the thiocyanate ion concentration required to inhibit 50% of the bound antibodies. The avidity was higher in symptomatic patients than asymptomatic healthy controls. IgG was less avid (0.92 M) compared to IgM (0.1 M) and IgA (1.1 M), with no correlation between antibody titer and avidity. However, the thiocyanate ion concentration required for the complete inhibition of IgG (5 M)-bound antibodies was higher than that of IgA (2 M) and IgM (3 M). This study also shows that C. jejuni antibodies were variably cross-reactive with Escherichia coli, Shigella flexneri, Shigella sonnei, and Neisseria meningitidis in addition to Campylobacter coli and Campylobacter rectus.

Hepatitis B virus (HBV) is endemic in the Kingdom of Saudi Arabia. The acquisition of infection occurs early in life. The availability of safe and efficacious vaccines has led to the feasibility of an effective control of HBV infection. This study compares the pattern of HBsAg positivity among selected groups of patients with similar groups in other regions in the Kingdom of Saudi Arabia.
This study is conducted to determine the prevalence of HBsAg positive subjects among selected groups of patients attending the main general hospital in the Hail region.
Subjects and Methods:
This retrospective study included 14029 subjects that were tested for HBsAg at King Khalid General Hospital, during the period from April 1994 to April 1996.
Results and Discussion:
The overall prevalence of HBsAg positive subjects was 3.5%. The prevalence for Saudis was about 3.2% for Saudis. Pakistanis had the highest prevalence of 11.8%. The prevalence was 3.02% for blood donors, and 2.1 % among pregnant women. No significant difference was found among different age groups. Hail region had a lower prevalence of HBsAg positive cases compared to that estimated by previous studies in the Kingdom, suggesting success in efforts applied by the Ministry of Health (110H) for prevention of Hepatitis B viral infection.
We can conclude that the prevalence of HBsAg positive subjects is declining in the Hail region, Kingdom of Saudi Arabia (KSA). This decline suggests the success of preventive efforts such as vaccination of newborns with the HBsAg vaccine. However, screening of pregnant women for HBsAg scents to be necessary.
