Cryptosporidiosis leading to an unsuspected diagnosis of AIDS.

We describe a 68-year-old woman with an episode of diarrhoea, malaise and weight loss, caused by infection with Cryptosporidium. The diagnosis was hampered because this patient had a low risk of HIV infection, a two-year history of Crohn's disease, and a simultaneous candidal infection. An infection with Cryptosporidium was demonstrated with electron microscopic examination, and subsequent tests revealed positive HIV serology. AIDS was probably contracted through her husband.

[Less operations required due to perioperative frozen section examination of sentinel nodes in 275 breast cancer patients].

OBJECTIVE: To determine the reliability of a peroperative frozen section examinations of sentinel lymph nodes in mammary carcinoma. DESIGN: Retrospective. METHOD: In the Reinier de Graaf Hospital and Diagnostic Centre SSDZ Delft, the Netherlands, the results of frozen section from sentinel lymph node investigations of mammary carcinomas from 1997-2000 were compared with the final pathological results. If axillary dissection had been performed on these patients, the histopathological findings of the dissected lymph nodes were also studied. RESULTS: Frozen sections were made of 287 sentinel lymph nodes from 275 patients. A tumour was found in the sentinel lymph nodes of 64 patients and these patients immediately underwent a complete axillary lymph node dissection. For 31 of these patients a tumour was also found in the other lymph nodes. In 29 of these 31 patients, histological examination had shown extranodal extension. The frozen sections from the sentinel nodes of the remaining 211 patients were considered negative. However, in 13 of these patients, the paraffin sections of the sentinel node nevertheless showed a tumour and the remaining axillary lymph nodes were removed in a second operation. In the last 89 patients studied, the sentinel lymph nodes were cut at four levels and stained immunohistochemically at one level for cytokeratins. Accordingly micrometastases were found in the sentinel lymph nodes of 4 of the 13 patients with (false-)negative frozen sections. False-positive results did not occur. CONCLUSION: The major advantage of the sentinel node method in breast cancer is that for women without metastasis present in the sentinel node, axillary dissection is avoided. By means of a peroperative examination of frozen sections, 83% of the patients with a metastasis in the sentinel lymph node (or about one quarter of all patients) were spared from having a second operation for axillary dissection at a later stage.

[Tubercular granulomas of the liver in a Somalian patient notwithstanding a chronic hepatitis C].

A 44-year-old male Somalian immigrant was admitted to hospital for evaluation of upper abdominal pain and painful joints (neck and shoulders). Chronic active hepatitis caused by hepatitis C virus was diagnosed. Further examination was instituted because of the simultaneous finding of granulomas in a liver biopsy. In hepatitis C liver granulomas may be found. Infection by Mycobacterium tuberculosis was established, however, after extensive investigation. Treatment was started with tuberculostatic drugs, after which the complaints of the patient disappeared, liver enzyme levels decreased and granulomas in the liver disappeared. No side effects of the tuberculostatic treatment were seen on the course of the hepatitis C.

Bacterial peptidoglycan polysaccharides in sterile human spleen induce proinflammatory cytokine production by human blood cells.

Peptidoglycan (PG) is the major component of the cell wall of gram-positive bacteria. In vitro, PG isolated from conventional bacterial cultures can induce secretion of proinflammatory cytokines by human monocytes, indicating that PG may be involved in immune responses against infections by gram-positive bacteria. To investigate the biologic activity of PG in human tissues, an improved method was developed to isolate significant amounts of PG from sterile human spleen tissue. Biochemical analysis demonstrated that PG isolated from human spleen is largely intact. Human whole blood cell cultures were able to produce the proinflammatory cytokines tumor necrosis factor-alpha and interleukin-1 and -6 after stimulation with PG isolated from human spleen. Cytokine induction was not sensitive to inhibition by polymyxin B, in contrast to lipopolysaccharide. Collectively, the data show that intact PG in sterile human tissue is biologically active and may induce local proinflammatory cytokine production.

Subtotal liver calcification due to epithelioid hemangioendothelioma.

A hepatic epithelioid hemangioendothelioma leading to almost complete calcification of the right and left liver lobes in a 75-year-old female is reported. Over a period of 16 years the liver progressively calcified, but its function remained normal by compensatory hypertrophy of the caudate lobe. Multiple partially calcified metastases were present in the lungs, peripancreatic region and along the left principal bronchus. Extreme liver calcification has only rarely been reported. The case presented here reflected slow tumor growth and subsequent long disease course. The vascular nature of the tumor was confirmed by immunohistochemical and ultrastructural analysis.

Histopathology of murine ankylosing enthesopathy.

Ankylosing enthesopathy is a spontaneously occurring progressive stiffening of the ankle and/or tarsal joints in mice of C57Black background. In C57BL/10 mice and mice of the same genetic background that had been made transgenic for HLA-B27, the start of the disease was detected by weekly testing for decreased mobility in the ankle/tarsus region. Ankylosing enthesopathy was found to begin with a short phase of proliferative inflammation of the joints and adjacent tissues, with some fibrinous exsudation, some leucocytic infiltration and slight bone erosion. This inflammation is soon accompanied and followed by proliferation of cartilaginous cells at the bone insertions of joint capsule ligaments (entheses). Ossification of the cartilage proliferations and some desmal ossification lead to large osteophytes that inhibit mobility. Fusion of osteophytes occasionally leads to marginal ankylosis. The histopathology of the successive stages of murine ankylosing enthesopathy and the preponderance in males and HLA-B27 transgenic mice are reminiscent of ankylosing spondylitis in man. The spine, however, was not affected.

[Gas gangrene of ischemic myocardial tissue caused by Clostridium septicum].

A 86-year-old woman hospitalized for analysis of persistent abdominal discomfort died, apparently of myocardial infarction, shortly after admission. Autopsy revealed extensive myocarditis caused by infection with Clostridium septicum. As a portal of entry a carcinoma of the colon was found. The association of colon carcinoma and bacteraemia with C. septicum is well established while colon carcinoma can lead to cardiac hypoxia through blood loss and anaemia. However, myocarditis caused by this organism is extremely rare.

HLA-B27 as a relative risk factor in ankylosing enthesopathy in transgenic mice.

HLA-B27 is a risk factor for several human diseases through a mechanism that is not yet understood. This article describes a naturally occurring joint disease in laboratory mice, ANKENT. ANKENT begins with mild inflammation and culminates in irreversible stiffening of the ankle and/or tarsal joints in one or both hind paws. The macroscopic and histologic features of ANKENT, its relationship to age, gender, and environment, and some immunologic aspects are considered. With respect to genetics, it is demonstrated that an HLA-B27 transgene is a relative risk factor for ANKENT. Its impact depends on the H-2 haplotype, reaching a relative risk value of 9.4 for C57Bl/10, H-2b males (p < 0.025). Several features of ANKENT are reminiscent of human AS: joint pathology, age and gender distribution, the presence of non-MHC as well as MHC risk factors (including HLA-B27), and the suspicion that environmental factors are involved.
