    Notes: Summary A 39-year-old patient with acquired immunodeficiency syndrome was diagnosed as having intestinal Enterocytozoon bieneusi microsporidiosis after persistent watery diarrhea for 30 months and a 16-kg weight loss. Microsporidian parasites were found by light and electron microscopy in tissue specimens of the duodenum, jejunum, and terminal ileum, and by light microscopic examination of stool specimens. When duodenal tissue sections obtained 16 months previously were reviewed retrospectively, E. bieneusi was also found. Until now, diagnosis of intestinal microsporidiosis has been based on examination of bioptic specimens of the upper small intestine because the sensitivity of new coprodiagnostic techniques has not been determined. Our findings of ileal microsporidiosis show that examination of the terminal ileum and ileal biopsy collection in tandem with colonoscopy is indicated for patients infected with human immunodeficiency virus and suffering from unexplained chronic diarrhea. The long-term course of our patient demonstrates that E. bieneusi, although not necessarily life threatening, can cause protracted debilitating diarrhea and wasting in severely immunodeficient patients.

    Description / Table of Contents: Zusammenfassung Anläßlich von 1802 Urinuntersuchungen bei 216 ambulanten Trägern von Nierenallotransplantaten wurden 274 signifikante Bakteriurien festgestellt. Bei 30 Patienten wurden rezidivierende oder chronisch persistierende Harnwegsinfekte beobachtet, wobei 399 Befunde von Urinuntersuchungen ausgewertet wurden (13,3 Untersuchungen pro Patient). Es handelte sich um 15 Patienten mit klinischer und/oder pathologisch-anatomisch verifizierter Transplantatpyelonephritis und um 11 Patienten mit Cystitis. Vier Patienten mit urologischen Komplikationen nach Transplantation wurden von der Studie ausgeschlossen. Besonderes Gewicht für die Diagnose einer Transplantatpyelonephritis erlangen kontinuierliche Leukozyturie und der Nachweis antikörperbedeckter Urinbakterien. Beide Befunde wurden bei allen Patienten mit Transplantatpyelonephritis mehrfach erhoben. Wichtige klinische Symptome sind Fieber und Dysurie. Im Gegensatz zur Kontrollgruppe mit Cystitis kann bei 13 von 15 Patienten mit Transplantatpyelonephritis eine Abnahme der Transplantatfunktion festgestellt werden; zwei Patienten wurden erneut dialysebedürftig. Eine weitere schwerwiegende Komplikation stellt die Urosepsis bei acht von 15 Patienten dar. Die Ergebnisse weisen mit 15 Erkrankungen bei 26 Patienten auf die Häufigkeit einer Transplantatpyelonephritis bei chronischer Harnwegsinfektion nach Nierentransplantation hin. Begünstigt wird ihr Auftreten durch eine Abflußbehinderung in den ableitenden Harnwegen (acht von 15 Patienten) und durch hochdosierte immunosuppressive Therapie: acht der 15 Patienten erhielten beim Auftreten der Pyelonephritis mehr als 10 mg Prednison/die. Durch Infektkontrolle konnte die Nierenfunktion bei drei Patienten gehalten werden, bei Abschluß der Untersuchung war die Funktionseinbuße des Transplantates bei vier Patienten teilweise reversibel.
    Notes: Summary Examinations of the urine in 216 kidney allograft recipients resulted in significant bacteriuria in 274 samples of 1,802 urines tested. Bacteruria was found in 30 patients with recurrent or chronic persistent infections of the urinary tract; this patient group was studied by examination of 399 urine samples (mean 13.3 samples per patient). Four patients suffered from urologic complications after kidney grafting and were excluded from the study; 15 patients were diagnosed clinically and/or histologically with transplant pyelonephritis, 11 patients with cystitis. Of main importance for the diagnosis of transplant pyelonephritis were findings of persistent leucocyturia and the presence of antibody-coated bacteria. Both of these findings were repeatedly seen in all patients with transplant pyelonephritis. Clinical symptoms included fever and dysuria. In contrast to patients suffering from cystitis, transplant function detoriated in 13 of 15 patients with transplant pyelonephritis; two patients had to be treated by hemodialysis. Septicemia occurred in eight of the 15 patients studied. The data illustrate the frequency of transplant pyelonephritis as observed in 15 of 26 patients accompaining chronic urinary tract infection after kidney allograft transplantation. As a predisposing factor, obstruction of the urinary tract was diagnosed in eight of the 15 transplant recipients with pyelonephritis. The prednisone dose was higher than 10 mg in eight of 15 patients at the time transplant infection was diagnosed. Successful antibiotic treatment resulted in stable transplant function in three patients; four patients exhibited even lower serum creatinine levels after therapy.

    Notes: Summary Recurrence of the original disease in the transplanted kidney is observed in 5.6%–9.3% of the patients. However, the clinical significance of recurrence is often minor. Diagnosis is easy in diseases with specific renal lesions, e.g., in dense deposit disease and IgA-nephropathy, but may be difficult if such a marker is missing. Recurrence is of special clinical importance in the following conditions: Membranoproliferative GN type I (in 33%, often severe) and type II (=dense deposit disease, recurrence in 90%, often minor), focal segmental glomerulosclerosis (in 48% of patients with a rapid course (〈3 years) and in 12% of patients with a longer duration of the original disease; often severe), membranous nephropathy (recurrence rather rare, but often serious), and primary hyperoxaluria (in 100%). Mesangial IgA deposits recur in half of the patients with IgA-nephropathy and anaphylactoid purpura, but clinical findings are often minimal. Recurrence in anti-GBM-nephritis and SLE is rare. The study of recurrence may contribute to a better understanding of many renal diseases.

    Notes: Abstract Six children with isolated neuronal intestinal dysplasia (NID) and unusual complications are presented. Three had meconium peritonitis, one of them in association with a solid pyloric atresia, one midgut volvulus, one rectal stenosis, and one jejunojejunal intussusception. These cases show that patients with isolated NID may present with a heterologous pattern of symptoms very different from those generally reported, indicating that NID may not be a distinct clinical entity. The symptomatology of NID seems to be directly correlated with the degree of functional defect of gut motility. NID should be suspected in any case of functional small-bowel obstruction.

    Notes: Summary A detailed description of the pathologic and radiologic features of two premature sibs with diastrophic dwarfism is presented. They were born after 28 and 35 weeks gestation respectively and each survived for only one hour. The parents are first cousins. Histological investigation revealed a generalized disturbance of the hyaline and elastic cartilage, with vacuolar degeneration of the intercellular substance. Formation of cysts and clefts ensued mainly in the central portions of articular cartilage and led to massive destruction and deformation of the large joints, especially of the hips. Also, the zones of resting, proliferative and columnating cartilage were shortened and revealed a reduced number of chondrocytes in the vacuolated ground substance. Many of the deformed, shortened tubular bones presented marked bowing of the diaphyses. The first child had a marked scoliosis that had already developed in the uterus. In both cases the cervical spine was extremely kyphotic, due to hypoplasia of the ventral portion of the vertebral bodies C4–C6. The resulting severe narrowing of the spinal canal and compression of the cord may very likely be responsible for the death of our patients.

    Notes: Summary Proteinuria and microhaematuria were observed in three siblings and one first-degree cousin. Histological examination of three kidney biopsies and one autopsy specimen shows the same diffuse glomerular lesions in all patients, characterized by mainly subendothelial but frequently transmembranous and mesangial deposits of a unique fibrillar structure, visible by electron microscopy. Examination by immunfluorescence gave inconstant findings. No serological abnormalities could be established. To our knowledge, such a pecular form of familial glomerulopathy has not been described so far.

    Notes: Abstract A hydropic stillborn female fetus of 22 weeks' gestation with shortlimbed skeletal dysplasia and brachyphalangy is described. The markedly shortened phalanges of both hands had a most unusual angel-like configuration radiologically. Histological examination and comparison with a normal hand of the same gestational age revealed this appearance to be due to disturbed enchondral ossification with premature calcification of epiphyseal cartilage and thickening and outfolding of diaphyseal bone as wing-shaped appositions. Magnetic resonance imaging of the fetus demonstrated marked hyperplasia of cartilage, most impressive in the pelvis. This new type of lethal bone dysplasia may be placed in the group of metatropic dysplasias and similar disorders.

    Description / Table of Contents: Zusammenfassung In der Literatur sind vier Fälle mit Entwicklung einer akuten myeloischen und sechs Fälle mit Entwicklung einer chronischen myeloischen Leukämie unter Immunosuppression mit Azathioprin und Prednison bei nierentransplantierten Patienten beschrieben. Wir berichten über zwei weitere akute Leukämien während chronischer Immunosuppression bei Zustand nach Nierentransplantation. Der erste, 29jährige Patient entwickelte zehn Jahre nach erfolgreicher Nierentransplantation die Zeichen einer akuten lymphatischen Leukämie. Beim zweiten, 47jährigen Patienten wurden fünf Jahre nach erfolgreicher Nierentransplantation Hepatosplenomegalie und Pancytopenie beobachtet; nach Splenektomie wurde die Diagnose einer subakuten myeloischen Leukämie gestellt. Beide Patienten standen unter langdauernder immunosuppressiver Therapie (Azathioprin und Prednison),die in beiden Fällen nach der Diagnose einer Leukämie abgesetzt wurde. Ein Zusammenhang zwischen dem Auftreten der Leukämie und der chronischen Immunosuppression wird postuliert.
    Notes: Summary Four cases of acute myelogenous leukemia and six cases of chronic myelogenous leukemia after treatment with azathioprine and prednisone for renal allotransplantation have been described in the literature. We report another two cases of acute leukemia 10 and 5 years after successful renal allotransplantation. Patient 1, a 29-year-old farmer, exhibited the signs of acute lymphatic leukemia resistent to treatment with cytostatic agents. Death was due to pneumonia. Patient 2, a 47-year-old salesman, developed pancytopenia together with splenomegaly. After splenectomy an atypical subacute myeloid leukemia became apparent which was not treated due to withdrawal of the patient. He died 2 months after diagnosis. Both patients received long-term immunosuppressive therapy with azathiopine and prednisone until the leukemia was diagnosed. A relationship between long-term immunosuppression and the occurrence of leukemia is postulated.

    Notes: Summary In the 33rd week of pregnancy an amniocentesis was performed because of low estriol. X-ray indicated the presence of anencephaly and a premature delivery was induced. Necropsy, in addition to anencephaly, showed a wide variety of malformations. The fetal karyotype determined from cultured amniotic fluid cells revealed a ring chromosome 13.
