Summary: A female patient with isovaleric acidaemia had a successful outcome from pregnancy.     

27-jähriger Reiserückkehrer mit hohem Fieber und septischem Schock im Verlauf

A 27-year-old man was admitted with high fever and shivers eleven days after returning from vacation in Indonesia. Physical examination, laboratory values, abdominal ultrasound, and chest x-ray were not conclusive. All blood cultures yielded growth of Salmonella enterica serovar Typhi, and typhoid fever was diagnosed. Subsequently, the patient developed septic shock and pulmonary edema.In this case report epidemiological, clinical, and therapeutic aspects of typhoid fever are discussed with special emphasis on criteria for severe typhoid fever, which is treated with additional glucocorticoids.     

The role of stem cells in suppurative environments

Purpose:  To evaluate all consecutive patients treated with infliximab for hidradenitis suppurativa (HS).
Patients and methods:  Within 1 year, all consecutive patients seen in our department for HS (1) resistant to usual medical therapies (2) which could not be easily cured by surgery (3) not treated with new medication within 2 months before inclusion were treated intravenously with infliximab (5 mg/kg) without corticosteroids premedication. Four infusions were planned (week 0, week 2, week 6 and week 10) before the interruption of therapy and follow-up. Clinical activity of HS and quality of life of the patients were assessed immediately before the first, the third and the fourth infusions of infliximab.
Results:  Seven patients were included. Five completed the four infusions. Two patients received only three infusions because of severe side effects. The Sartorius score moderately improved with infliximab (mean score at week 0: 94 ± 39, at week 6: 71 ± 38 and at week 10: 83 ± 48). At week 6, patients judged the efficacy of therapy as marked ( n  = 1), moderate ( n  = 4) or null ( n  = 2). At week 10, five patients were evaluated and judged this efficacy as marked ( n  = 2), moderate ( n  = 2) or null ( n  = 1). The mean Skindex-29 score varied from 22 ± 11 (E: 25 ± 9, S: 13 ± 5, F: 28 ± 12) at week 0 to 18 ± 10 (E: 22 ± 8, S: 12 ± 8, F: 22 ± 12) at week 10.
Conclusion:  The efficacy of infliximab in severe HS is partial. More experience is needed before finding a place for infliximab in the therapeutic armamentarium for HS.     

The diagnostic utility of immunohistochemistry and electron microscopy in distinguishing between peritoneal mesotheliomas and serous carcinomas: a comparative study.

The histologic distinction between peritoneal epithelioid mesotheliomas and serous carcinomas diffusely involving the peritoneum may be difficult, but it can be facilitated by the use of immunohistochemistry and electron microscopy. D2-40 and podoplanin are two recently recognized lymphatic endothelial markers that can be expressed in normal mesothelial cells and mesotheliomas. The purpose of this study is to compare the value of these new mesothelial markers with those that are commonly used for discriminating between mesotheliomas and serous carcinomas, and also to determine the current role of electron microscopy in distinguishing between these malignancies. A total of 40 peritoneal epithelioid mesotheliomas and 45 serous carcinomas of the ovary (15 primary, 30 metastatic to the peritoneum) were investigated for the expression of the following markers: D2-40, podoplanin, calretinin, keratin 5/6, thrombomodulin, MOC-31, Ber-EP4, B72.3 (TAG-72), BG-8 (Lewis(Y)), CA19-9, and leu-M1 (CD15). All 40 (100%) of the mesotheliomas reacted for calretinin, 93% for D2-40, 93% for podoplanin, 93% for keratin 5/6, 73% for thrombomodulin, 13% for Ber-EP4, 5% for MOC-31, 3% for BG-8, and none for B72.3, CA19-9, or leu-M1. All 45 (100%) serous carcinomas were positive for Ber-EP4, 98% for MOC-31, 73% for B72.3, 73% for BG-8, 67% for CA19-9, 58% for leu-M1, 31% for keratin 5/6, 31% for calretinin, 13% for D2-40, 13% for podoplanin, and 4% for thrombomodulin. After analyzing the results, it is concluded that Ber-EP4 and MOC-31 are the best negative mesothelioma markers for differentiating between epithelioid mesotheliomas and serous carcinomas. The best discriminators among the positive markers for mesotheliomas are D2-40, podoplanin, and calretinin. From a practical point of view, Ber-EP4 and MOC-31, in combination with calretinin, and/or D2-40 or podoplanin allow the differential diagnosis to be established between mesothelioma and serous carcinoma in nearly all instances. As a clear distinction could be made between these two malignancies in all of the cases in which electron microscopy was performed, this technique can be very useful in establishing the correct diagnosis when the immunohistochemical results are equivocal or further support of a diagnosis of either mesothelioma or serous carcinoma is needed.
