Correlation of tumour markers in ascitic fluid and serum: are measurements of ascitic tumour markers a futile attempt?

Correlations between tumour markers in ascitic fluid and serum were investigated to determine whether ascitic fluid analysis had any diagnostic advantage over serum in 91 adults with ascites (55 malign; 36 benign). Serum and ascitic fluid were analysed for carcinoembryonic antigen (CEA), cancer antigen (CA) 125, CA19.9, CA72.4, CA15.3, alpha-fetoprotein (AFP) and cytokeratin-19 fragment (CYFRA). The tumour markers were skewed between the groups so were logarithmically transformed. Correlations between serum and ascitic fluid were tested using Pearson's correlation coefficient. Serum and ascitic fluid levels of CEA, CA125, CYFRA and AFP in the malign group were statistically different and CEA, CA19.9, CA5.3, CYFRA and AFP were statistically different in the benign group. For both groups, all tumour markers were highly correlated in serum and ascitic fluid, with the exception of CYFRA in the malign group. These results indicate that, where malignant ascites is suspected, analysing tumour markers in ascitic fluid does not have any advantage over serum analysis.

How to increase the diagnostic value of malignancy-related ascites: discriminative ability of the ascitic tumour markers.

Making a differential diagnosis between malignant and non-malignant ascites is an important clinical issue, but cytological examination has a relatively low diagnostic sensitivity. This study aimed to find a discriminative model that distinguished between malignancy-related and non-malignant ascites. The study included 107 patients: 50 with non-malignant and 57 with malignant ascites. Ascites was analysed using a range of tumour markers and standard cytology. Standardized canonical discriminant function coefficients were used to distinguish between ascites types. The combination of carbohydrate antigen (CA) 15-3, carcinoembryonic antigen (CEA) and cytokeratin 19 fragments (CYFRA-21.1) discriminated between malignancy-related ascites and non-malignant ascites with an accuracy of 98.8% compared with an accuracy of 77.8% for cytological examination. In conclusion, the use of a discriminant function constructed from a combination of CA15-3, CEA and CYFRA-21.1 could distinguish malignant from non-malignant ascites with greater accuracy than cytological examination. Further studies in larger population groups are warranted.

Intramedullary angioma with bilateral arm hypothermia.

Spinal cavernous malformations are collections of abnormal blood vessels in the spinal cord. They are rare and frequently accompany cranial cavernous angiomas. They exhibit clinical features representing the region of the spine affected by the cavernous malformation. We present a 12-year-old boy with bilateral hypothermia predominantly in the left arm and motor weakness of the upper extremities, and lesser involvement of the lower extremities The case had normal cranial magnetic resonance imaging, but MRI of cervical region revealed an intramedullary cavernous haemangioma confirmed with histopathological examination. The lesion was totally excised and hypothermia completely improved within 2 weeks after operation. We suggested that hypothermia in the extremities may be added as a rare finding to the list of the clinical features in cervical myelopathy.

Clinicopathologic evaluation of nodular cutaneous lesions of Behçet syndrome.

Among the cutaneous manifestations, nodular lesions are rather common in Behçet syndrome. The histologic nature of these lesions has been a matter of controversy. To establish their distinguishing features, biopsy specimens from nodular lesions of 24 patients with Behçet syndrome, 25 with nodular vasculitis (NV), and 20 with erythema nodosum (EN) were compared. Statistical analysis revealed insignificant differences between most of the histologic features of Behçed syndrome and NV. However, neutrophil-predominating infiltrate in the subcutis was more common in Behçet syndrome, while necrosis and granuloma formation were encountered more frequently in NV. The differences between Behçed syndrome and EN were more significant. Septal panniculitis, lymphocyte-predominating infiltrate, absence of many vascular changes as well as vasculitis, and necrosis were features in favor of EN. Nodular lesions of Behçet syndrome are mainly neutrophilic vascular reactions with histologic features similar to NV but significantly differing from EN associated with other systemic diseases.

Short term cyclosporin A treatment of Behçet's disease.

Eleven separate three-month courses of cyclosporin A, an oral solution 10 mg/kg/day, were administered to eight patients with Behçet's disease with sight-threatening posterior uveitis. It was found to be effective in arresting the inflammatory activity in the eye as well as the mucocutaneous lesions of Behçet's disease. Improvement in visual acuity was observed within one week of starting therapy. Severe exacerbations in the ocular and mucocutaneous lesions occurred on withdrawal of the drug. At this dosage side effects included hirsutism in all women, and a slight rise of serum bilirubins in two patients and of blood urea in one patient. The latter two conditions responded rapidly to dose adjustment.

Diabetic sclerodactyly.

Sclerodactyly is a chronic skin disorder seen together with long-term degenerative microvascular complications of diabetes mellitus. In this study, the relationship between sclerodactyly and various clinical and laboratory characteristics of diabetes mellitus have been investigated. One hundred and forty-two diabetic patients (63 type 1 and 79 type 2) and 72 healthy controls were evaluated clinically. Among the 142 diabetic patients, skin biopsies were taken from 21; 38 underwent soft tissue X-ray examination and 78 underwent periungual capillaroscopy. Among the healthy controls those with sclerodactyly were on the average 12 years older than those without (T: 3.38; P < 0.01). On the other hand, among the patients with either type 1 or type 2 diabetes mellitus the ages were similar between those with and without sclerodactyly. There were no statistically significant differences in the prevalence of diabetic complications. The presence of complications, increased proximal nail fold capillarity, HbA1c levels, radiological and histopathological findings were not different among those patients who had or did not have sclerodactyly.

Low dose cyclosporin A versus pulsed cyclophosphamide in Behçet's syndrome: a single masked trial.

A single masked trial of cyclosporin A 5 mg/kg/day versus monthly 1 g intravenous boluses of cyclophosphamide was conducted among 23 patients with Behçet's syndrome and active, potentially reversible uveitis. The trial was unmasked after a mean of 12 (SD 2) months for the cyclosporin A group (n = 12) and a mean of 10 (SD 3) months for the cyclophosphamide group (n = 11). During the initial 6 months the visual acuity significantly improved (p < 0.001) in the cyclosporin A group whereas this was not observed in the cyclophosphamide group. The subsequent follow-up of patients up to 24 months suggested that the initial improvement in visual acuity with cyclosporin A was not sustained. More extensive and especially long-term studies of cyclosporin A in the uveitis of Behçet's syndrome are warranted.

Sebum production is increased in Behçet's syndrome and even more so in rheumatoid arthritis.

Sebum production is under hormonal control. We had shown that male sex is associated with more severe disease in Behçet's syndrome and the acneiform skin lesion of this disorder is not different from ordinary acne, an androgen-dependent lesion. Sebum excretion rate was higher in patients with Behçet's syndrome than in healthy controls, children and patients with ankylosing spondylitis. On the other hand, patients with rheumatoid arthritis had high levels of sebum excretion rate comparable to those found in patients with acne vulgaris. These suggest the presence of a sebotrophic hormone and/or other hormonal effects in Behçet's syndrome and rheumatoid arthritis.

HLA antigens in recurrent oral ulceration: evidence against a common disease spectrum with Behçet's syndrome.

Among 50 patients with recurrent oral ulceration (ROU) the prevalence of HLA B5 was not increased as was the case among 50 patients with Behçet's Syndrome (BS) compared to 52 healthy controls. On the other hand, HLA DR4 was present in 16 of 30 (53%) patients with ROU whereas the same allele was present in 16% of BS patients and 22% of the healthy controls. These findings suggest that ROU and BS are not in the same disease spectrum.

Topical alpha interferon in the treatment of oral ulcers in Behçet's syndrome: a preliminary report.

The effect of topical recombinant interferon alfa 2c hydrogel (IFN alpha 2C) in the aphthous lesions of the mouth in Behcet's syndrome was assessed in twenty patients in a twelve-week open trial. IFN alpha 2C applied to the mouth for four weeks significantly reduced the number of aphthae in the post-treatment phase compared to the pretreatment and treatment phases. No side effects were recorded. Topical IFN alpha 2C seems to be effective in the treatment of the aphthae in Behcet's syndrome.

Male patients with Behçet's syndrome have stronger pathergy reactions.

The effects of patient's sex and age at onset on the pathergy reaction (cutaneous hypersensitivity to a needle prick) and its correlation with disease activity in Behcet's syndrome was investigated by two independent observers in a blind protocol. Among 92 male patients the pathergy reaction was more strongly positive (p less than 0.025) than among 67 female patients of similar age and disease duration. The age at onset did not affect the severity of the pathergy reaction, although, the early onset females (age at onset 24 years or less) had the lowest prevalence of pathergy positivity (52%), compared to early onset males and late onset (age at onset 25 years or more) males and females (73-75%). As previously reported the disease was more severe among males and among those with early onset of either gender. On the other hand, no correlation between the strength of the pathergy reaction and clinical severity could be discerned.

Intramedullary spinal tuberculoma: a case report.

STUDY DESIGN: A case report showing an intramedullary thoracic spinal tuberculoma secondary to pulmonary tuberculosis in a 16-year-old patient with findings of subacute spinal cord compression. OBJECTIVES: The significance and the use of magnetic resonance imaging in the diagnosis of intramedullary tuberculoma, and the treatment of the patient that involves surgically the excision of intramedullary lesion followed by appropriate antituberculous therapy. SUMMARY OF BACKGROUND DATA: Tuberculomas of spinal cord are rare entities. The possibility of intramedullary tuberculoma should be seriously considered when an intraspinal mass is found, provided that pulmonary tuberculosis is present in the history of the patient. METHOD: Th4-Th5 laminectomy was performed. Intramedullary tuberculoma was excised through a myelotomy. Antituberculous treatment was applied after the surgery. RESULTS: Excellent clinical outcome was obtained with a combination of both medical and surgical treatments. CONCLUSION: The intramedullary spinal tuberculoma, although a rare entity, must be considered in the differential diagnosis of the spinal cord compression in patients with a history of tuberculosis, human immunodeficiency virus, and those who have a bad socioeconomic condition and bad nutrition habit. When confronted with a progressing neurologic deficit, a combination of microsurgical resection and antituberculous chemotherapy with the avoidance of steroids should be the choice of treatment for intramedullary tuberculomas.

Behçet's syndrome. The Cerrahpasa experience. Members of the Behçet's Syndrome Research Centre.

Behçet's syndrome (BS) is a systemic vasculitis of unknown etiology. There are several reasons for doubting a primary autoimmune pathogenesis of this condition. Recent information suggests evidence for genetic anticipation. Although there is heightened inflammatory activity, as exemplified by the pathergy reaction, wound healing in BS is normal. BS also runs a more stormy course in adults and in the young. However, the amount of androgen receptors in scrotal skin have not found to be increased. Another unsolved problem is the nature of acne-like lesions and how they differ from acne vulgaris (AV). Only lesions in "non-acne" areas were compared between the two conditions, and no differences were detected. Mortality is increased in BS, especially among males. Azathioprine proved to be effective in disease control after 8 years of follow-up. We have also recently finished a 24 week controlled trial of two doses of thalidomide, 100 mg and 300 mg per day. Both doses were superior to placebo, with no real differences in efficacy, in controlling the oral and genital ulcers.

Primary multiple hydatid cysts localizing in the petroclival area.

Hydatid cyst of the posterior fossa is very rare. In this report we present a 22-year-old female who had primary multiple hydatid cysts localizing in the petroclival areas. The report is noteworthy because of the unusual location, and the cranial and spinal dissemination of cysts despite previous treatment.
