Abstract
Decreased circulating branched chain amino acids (BCAA) represent a prominent change in amino acid profiles in patients with end-stage liver disease (ESLD). These alterations are considered to contribute to sarcopenia and hepatic encephalopathy and may relate to poor prognosis. Here, we cross-sectionally analyzed the association between plasma BCAA levels and the severity of ESLD and muscle function in participants of the liver transplant subgroup of TransplantLines, enrolled between January 2017 and January 2020. Plasma BCAA levels were measured by nuclear magnetic resonance spectroscopy. Physical performance was analyzed with a hand grip strength test, 4 m walking test, sit-to-stand test, timed up and go test, standing balance test and clinical frailty scale. We included 92 patients (65% men). The Child Pugh Turcotte classification was significantly higher in the lowest sex-stratified BCAA tertile compared to the highest tertile (p = 0.015). The times for the sit-to-stand (r = -0.352, p < 0.05) and timed up and go tests (r = -0.472, p < 0.01) were inversely correlated with total BCAA levels. In conclusion, lower circulating BCAA are associated with the severity of liver disease and impaired muscle function. This suggests that BCAA may represent a useful prognostic marker in the staging of liver disease severity.

Abstract
Glycogen storage disease type 1a (GSD Ia) is an inborn error of metabolism caused by mutations in the G6PC gene, encoding the catalytic subunit of glucose-6-phosphatase. Early symptoms include severe fasting intolerance, failure to thrive and hepatomegaly, biochemically associated with nonketotic hypoglycemia, fasting hyperlactidemia, hyperuricemia and hyperlipidemia. Dietary management is the cornerstone of treatment aiming at maintaining euglycemia, prevention of secondary metabolic perturbations and long-term complications, including liver (hepatocellular adenomas and carcinomas), kidney and bone disease (hypovitaminosis D and osteoporosis). As impaired vitamin A homeostasis also associates with similar symptoms and is coordinated by the liver, we here analysed whether vitamin A metabolism is affected in GSD Ia patients and liver-specific G6pc−/− knock-out mice. Serum levels of retinol and retinol binding protein 4 (RBP4) were significantly increased in both GSD Ia patients and L-G6pc−/− mice. In contrast, hepatic retinol levels were significantly reduced in L-G6pc−/− mice, while hepatic retinyl palmitate (vitamin A storage form) and RBP4 levels were not altered. Transcript and protein analyses indicate an enhanced production of retinol and reduced conversion the retinoic acids (unchanged LRAT, Pnpla2/ATGL and Pnpla3 up, Cyp26a1 down) in L-G6pc−/− mice. Aberrant expression of genes involved in vitamin A metabolism was associated with reduced basal messenger RNA levels of markers of inflammation (Cd68, Tnfα, Nos2, Il-6) and fibrosis (Col1a1, Acta2, Tgfβ, Timp1) in livers of L-G6pc−/− mice. In conclusion, GSD Ia is associated with elevated serum retinol and RBP4 levels, which may contribute to disease symptoms, including osteoporosis and hepatic steatosis.

Abstract
Background: Retinol binding protein 4 (RBP4) carries retinol in plasma, but is also considered an adipokine, as it is implicated in insulin resistance in mice. Plasma RBP4 correlates with total cholesterol, low density lipoprotein (LDL)-cholesterol and triglycerides, and may confer increased cardiovascular risk. However, controversy exists about circulating RPB4 levels in type 2 diabetes mellitus (T2DM) and obesity. Here, we analyzed the relationships of RBP4 and retinol with lipoprotein subfractions in subjects with and without T2DM. Methods: Fasting plasma RBP4 (enzyme-linked immunosorbent assay) and retinol (high performance liquid chromatography) were assayed in 41 T2DM subjects and 37 non-diabetic subjects. Lipoprotein subfractions (NMR spectroscopy) were measured in 36 T2DM subjects and 27 non-diabetic subjects. Physical interaction of RBP4 with lipoproteins was assessed by fast protein liquid chromatography (FPLC). Results: Plasma RBP4 and retinol were strongly correlated (r = 0.881, p < 0.001). RBP4, retinol and the RBP4/retinol ratio were not different between T2DM and non-diabetic subjects (all p > 0.12), and were unrelated to body mass index. Notably, RBP4 and retinol were elevated in subjects with metabolic syndrome (p < 0.05), which was attributable to an association with elevated triglycerides (p = 0.013). Large VLDL, total LDL and small LDL were increased in T2DM subjects (p = 0.035 to 0.003). Taking all subjects together, RBP4 correlated with total cholesterol, non-HDL cholesterol, LDL cholesterol, triglycerides and apolipoprotein B in univariate analysis (p < 0.001 for each). Age-, sex- and diabetes status-adjusted multivariable linear regression analysis revealed that RBP4 was independently associated with large VLDL (β = 0.444, p = 0.005) and small LDL particles (β = 0.539, p < 0.001). Its relationship with large VLDL remained after further adjustment for retinol. RBP4 did not co-elute with VLDL nor LDL particles in FPLC analyses. Conclusions: Plasma RBP4 levels are related to but do not physically interact with large VLDL and small LDL particles. Elevated RBP4 may contribute to a proatherogenic plasma lipoprotein profile.

Abstract
Endothelial-dependent regulation of vascular tone occurs in part via protein kinase G1α-mediated changes in smooth muscle myofilament sensitivity to Ca(2+). Tissue-specific differences in PKG-dependent relaxation have been attributed to altered expression of myofilament-associated proteins that are substrates for PKG binding. These include the alternative splicing of the myosin targeting subunit (MYPT1) of myosin light chain phosphatase to yield leucine zipper positive (LZ(+)) and negative (LZ(-)) isovariants, with the former being required for PKG-mediated relaxation, and/or altered expressions of telokin, vasodilator-stimulated phosphoprotein (VASP) or heat shock protein Hsp20. During human pregnancy the uterine and placental circulations remain distinct entities and, as such, their mechanisms of vascular tone regulation may differ. Indeed, the sensitivity of myometrial arteries to endothelial-dependent agonists has been suggested to be greater than that of placental arteries. We tested the hypothesis that this was related to tissue-specific changes in PKG-mediated myofilament Ca(2+)-desensitization and/or the expressions of PKG-interacting myofilament-associated proteins. Permeabilized human placental and myometrial arteries were constricted with maximal activating Ca(2+) (pCa 4.5), or sub-maximal Ca(2+) (pCa 6.7) and the thrombane mimetic U46619, and exposed to 8-Br-cGMP. In each case, relaxation was significantly greater in myometrial arteries (e.g. relaxation in pCa 4.5 to 8-Br-cGMP was 49 ± 9.7%, n = 7) than placental arteries (relaxation of 23 ± 6.6%, n = 6, P < 0.05). MYPT1 protein levels, or MYPT1 LZ(+)/LZ(-) mRNA ratios, were similar for both artery types. Of other proteins examined, only Hsp20 expression was significantly elevated in myometrial arteries than placental arteries. These results demonstrate that the reduced human placental artery relaxation to PKG stimulation lies partly at the level of myofilament (de)activation and may be related to a lower expression of Hsp20 than in myometrial arteries.

Abstract
BACKGROUND If parturients prone to develop caval compression in the supine position were identified before delivery, this might be a method of predicting hypotension during caesarean section under spinal anesthesia. Colloid preloading is superior to crystalloid in reducing the risk for spinal anesthetic-induced hypotension. It is postulated that parturients preoperatively susceptible to the supine position would benefit the most from colloid preloading. METHODS Fifty-five healthy parturients scheduled for elective cesarean section under spinal anesthesia were preoperatively investigated with a supine stress test with measurement of maternal heart rate, blood pressure, right uterine artery pulsatility index and symptoms in the left lateral and supine positions. They were then randomized to receive a colloid or crystalloid preload before anesthesia. RESULTS The stress test was positive, indicating a reduced tolerance to the supine position, in 36%. The sensitivity and specificity of the stress test for clinically significant hypotension (symptomatic hypotension) for patients randomized to the crystalloid group (n=25) were 69 and 92% respectively. Patients with a positive stress test receiving a crystalloid preload showed a higher frequency of hypotension compared to all other groups, 90% vs. 33%, (P=0.003) and also a greater need for ephedrine, mean dose (SD): 20.0 (9.7) vs. 8.4 (9.0) mg (P=0.002). CONCLUSIONS Pregnant women with a positive preoperative supine stress test constitute a subset at increased risk for clinically significant hypotension during cesarean delivery under spinal anesthesia. These women seem more likely to benefit from prophylactic colloid solution than women with a negative stress test.

Abstract
BACKGROUND Hypotension associated with spinal anesthesia for cesarean section is still a clinical problem. Colloid solutions seem preferable to crystalloid solutions for preloading. In most studies the overall rate of hypotension is reported. Few studies have, however, investigated the maternal and neonatal consequences of different levels of maternal hypotension. METHODS In this randomized, double-blinded study 110 patients presenting for elective cesarean section received either 1000 ml acetated Ringer's solution or 1000 ml 3% dextran 60 solution immediately before spinal anesthesia. The effect on overall hypotension, clinically significant hypotension (hypotension associated with maternal discomfort defined as nausea, retching/vomiting, dizziness or chest symptoms) and severe hypotension (systolic arterial pressure <80 mmHg) was studied. RESULTS Dextran reduced the incidence of overall hypotension from 85 to 66% (P=0.03), reduced the incidence of clinically significant hypotension from 60 to 30% (P=0.002) and reduced the incidence of severe hypotension from 23 to 3.6% (P=0.004) compared to Ringer's solution. There were neither differences in neonatal outcome between treatment groups nor between neonates grouped after severity of maternal hypotension. CONCLUSION Clinically significant hypotension seems to be a more suitable outcome variable than overall hypotension. The protective effect of the colloid solution increased with increased severity of hypotension.

Abstract
PURPOSE To determine whether temporal and spatial changes in the distribution of the long and short alternatively spliced variants of type XII collagen are associated with any specific morphogenetic events in pre- and postnatal development of the cornea and surrounding tissues. METHODS The distribution of alternatively spliced variants of type XII collagen in fetal and newborn rabbit tissues was analyzed immunohistochemically using monoclonal antibodies that recognize either only the long form or both the short and the long forms of type XII collagen. RESULTS During early fetal development of the cornea in rabbit (days 14 -17), the short form of type XII collagen was detected in the corneal stroma, the sclera, and the stroma in the rudimentary eyelid folds, whereas the long form was present only in the sclera. The long form was first evident in the cornea at day 24 but only in the posterior stroma. At later stages of prenatal development, the distribution of the long variant gradually extended toward the anterior stroma and in the newborn rabbit, the long variant was distributed throughout the entire stroma. However, in the eyelid, although the short form was present along the entire subepidermal regions both during fetal and neonatal development, the long form was transiently expressed between days 21 and 24 and was restricted to the subepidermal regions at the junction of the opposing eyelids. The long form of type XII collagen was first detectable in the basal epithelial cells and in its basement membrane (BM) at day 12 after birth, just before the opening of the eyelids. It continued to be present in the corneal BM zone in the adult rabbit but was not present in the limbal or conjunctival BM zone. CONCLUSIONS The expression and distribution of the alternatively spliced forms of type XII collagen are developmentally and differentially regulated in the cornea, the sclera, and the eyelid. Although the short form is expressed in the stromal matrices of the cornea and surrounding tissues from early stages of corneal development, the appearance and distribution of the long variant form of type XII collagen coincide with the pattern of stromal condensation. Its first appearance in the corneal epithelial BM precedes the eyelid opening by 1 to 2 days, possibly suggesting that it may be involved in the tighter anchoring of the corneal epithelium to the underlying tissue or in promoting stromal condensation to assist in the separation of the corneal epithelium from the juxtaposed palpebral conjunctival epithelium of the eyelid.

Abstract
OBJECTIVE To determine the frequency of calpain III mutations in a heterogeneous limb-girdle muscular dystrophy (LGMD) population. BACKGROUND Mutations of the calpain III gene have been shown to cause a subset of autosomal recessive LGMDs. Patient populations studied to date have been primarily of French and Spanish origin, in which calpain III may cause 30% of autosomal recessive MDs. The incidence of calpain III mutations in non-French/Spanish MD patients has not been studied thoroughly. No sensitive and specific biopsy screening methods for detecting patients with abnormal calpain III protein are available. Thus, detection of patients relies on direct detection of gene mutations. METHODS The authors studied the calpain III gene in 107 MD patient muscle biopsies exhibiting normal dystrophin. Muscle biopsy RNA was produced for each patient, and the entire calpain III complementary DNA was screened for mutations by reverse-transcriptase PCR/single-strand conformation polymorphism using three different conditions. RESULTS The authors identified nine patients (eight unrelated) with causative mutations. Six of the seven distinct mutations identified are novel mutations and have not been described previously. CONCLUSION The results suggest that approximately 9.2% of patients in the heterogeneous population with an LGMD diagnosis will show mutations of the calpain III gene. Interestingly, two patients were heterozygous for a single mutation at the DNA level, whereas only the mutant allele was observed at the RNA level. This suggests that there are undetectable, nondeletion mutations that ablate expression of the calpain III gene.

Abstract
SUBJECT In 1992-93 all deaths (n=97) of women 15 to 49 years old in three islands of Cape Verde were investigated to determine the cause of death, the maternal mortality ratio, the reliability of cause-of-death ascertainment, and the level of avoidability. METHOD Data were obtained through interviews with the deceased person's family members and other knowledgeable persons (verbal autopsy) and through hospital files. RESULTS The overall mortality rate was 163 per 100,000 women 1549 years old, and the maternal mortality ratio was 127 per 100,000 live births. A plausible diagnosis could be determined in 77%. The most frequent causes of death were circulatory disorders, external causes, maternal causes, infectious diseases. and neoplasms. CONCLUSIONS It was estimated that three of four of the deaths were avoidable with locally available resources. Since access to health care in the study area is not a major hindrance, a further decrease of female mortality depends mainly on improved quality of care in health facilities.

Abstract
PURPOSE The authors have developed monoclonal antibodies (mAbs) to characterize the sequential biochemical changes in corneal epithelial cells after they differentiate from stem cells, located in the limbus, and migrate centripetally to follow the pathway of terminal differentiation. The purpose of this study was to identify a protein (recognized by mAb HE1/11F) with increased expression associated with the transition of the limbal epithelium to corneal epithelium. METHODS The distribution and identification of the protein(s) were performed using an indirect immunohistochemical staining technique and a western blot analysis, respectively. A rabbit corneal epithelial cDNA library, constructed in the Uni-Zap XR vector, was screened with mAb HE1/11F to select cDNA clones expressing polypeptide(s) recognized by this mAb. Additional overlapping cDNA clones were obtained from a primer extension cDNA library to determine the sequence of the complete open reading frame encoding the protein recognized by mAb HE1/11F. RESULTS Rabbit corneal epithelium exhibited strong immunostaining with mAb HE1/11F, however, the limbal epithelial cells stained weakly. HE1/11F recognized 160-kDa (HEBM1) and 100-kDa (HEBM2) polypeptides in the corneal epithelial extracts. The amino acid sequence of the protein deduced from the nucleotide sequence of the cDNA exhibited a close homology to that of a RhoA (Ras-related small GTPase)-associated serine-threonine kinase (ROCK-I or Rho-associated coiled-coil kinase). A 160-kDa RhoA-binding polypeptide with a molecular mass similar to that of HEBM1 and ROCK-I was detected in the corneal epithelial extracts. These findings strongly suggested that HEBM1 was rabbit ROCK-I. The identity of HEBM1 was further confirmed from the reactivity of mAb HE1/11F with ROCK-I immunoprecipitated from rabbit corneal epithelial extracts using anti-ROCK-I antibodies. CONCLUSIONS The increased expression of a protein identified as ROCK-I from cDNA analyses is associated with rabbit corneal epithelial differentiation and transition from the limbal to corneal surface. Therefore, a RhoA signaling pathway is likely to be associated with corneal epithelial differentiation (maturation). A close homology among the cDNA sequences of rabbit, mouse, rat, and human ROCK-I indicates that this RhoA-associated kinase is a well-conserved protein.

Abstract
Risk factors for perinatal death in the Cape Verde islands were assessed among 104 bereaved mothers and 292 mothers of surviving infants in an area-based case-control study in 1992-93. Prospectively gathered information on risk factors was obtained from medical records supplemented with post-partum interviews and anthropometric measurements of mothers and infants. No autopsies were performed. Multiple logistic regression analysis was applied. Out of 23 alleged maternal and two alleged infant risk factors, the following seven proved significantly and independently correlated with perinatal death: first pregnancy (odds ratio [OR] = 2.9); previous hypertensive disease (OR = 4.2); previous perinatal death (OR = 4.6); pre-eclampsia (OR = 7.0); non-cephalic fetal presentation (OR = 17.1); male infant (OR = 2.1) and maternal post-partum fever (OR = 3.1). The perinatal mortality rate was calculated as 37-46/1000 total births. A reduction in the mortality rate warrants antenatal and obstetric care with emphasis on primiparous women; improved detection and treatment of hypertensive disorders and genital infections; and improved intrapartum fetal observation and resuscitation routines.

Abstract
PURPOSE To characterize diversities in the extracelhtlar matrices (ECMs) of the corneal and the surrounding limbal epithelium and stroma. METHODS Immunohistochemical analyses were employed for screening monoclonal antibodies (mAbs) developed against ECM components of the human corneal epithelial basement membrane (BM) zone. In the current study, mAb BM8 was used as the monospecific probe to characterize its antigen (AgBM8) immunochemically, and to immunoselect a complementary DNA (cDNA) clone encoding AgBM8. Direct biochemical and cDNA sequence analyses were performed for the further characterization of AgBM8. An indirect colloidal gold-conjugated antibody technique was employed for immunoelectron microscopic analysis to study the distribution of AgBM8 in the corneal ECMs. RESULTS The protein AgBM8, isolated from rabbit corneal stromal and epithelial tissues, was identified as the long-splice variant form of type XII collagen based on its size (approximately 340 kDa disulfide-linked subunits), the presence of collagenous domain(s) and a noncollagenous domain of approximately 300 kDa in its subunit structure, and its internal amino acid sequences. The identity of AgBM8 was further confirmed from the amino acid sequence (517 amino acids) deduced from the sequence of a cDNA immunoselected with mAb BM8. Immunofluorescence analyses indicated that the long form of type XII collagen is present in the ECMs of corneal stroma and in the sclera, as well as in the corneal epithelial BM zone but is absent in the limbal and conjunctival epithelial BM zones. It was not detectable in the subepithelial loose connective tissues in the limbus and in the bulbar conjunctiva. Immunoelectron microscopic analyses indicated that the long variant form of type XII collagen is present in corneal epithelial BM, Bowman's membrane, and the interfibrillar matrix of the corneal stroma. In the stroma, colloidal gold was distributed along the collagen fibrils with a periodicity of 150 to 200 nm. CONCLUSIONS The long variant form of human type XII collagen, a member of the fibril-associated collagens with interrupted triple helices, referred to as FACITs, contributes to the differences in the BM zones of the cornea and limbus. Although many of the dense connective tissues in adult animals contain the short variant form of type XII collagen, human corneal stroma, the BM zone, and the sclera contain the long variant form as the predominant form of type XII collagen. In the corneal stroma, type XII collagen may be organized along the collagen fibrils in a uniform head-to-tail pattern.

Abstract
The authors report a case of a 6-year-old boy in whom aberrant thymic tissue was misdiagnosed as an intrathyroidal solid lesion. The patient underwent hemithyroidectomy and did well. Because cervical ectopic thymus rarely produces symptoms, the true incidence in children is unclear. Surgeons need to consider this rare entity, not to mistake it as a thyroid neoplasm, and not to perform extensive thyroid resection.

Abstract
A single-tube nested PCR method was developed for the detection of Neisseria gonorrhoeae. The optimized assay had a detection limit of less than 0.3 cell. Five different storage conditions for gonococcal specimens were compared with respect to the PCR detection of bacteria. For air-dried gonococcal slides containing three bacteria, DNA was detected after 8 weeks at ambient temperature, and for slides containing 300 bacteria, DNA could be detected after 24 weeks at ambient temperature. Air-dried storage combined with analysis by the single-tube nested PCR and a commercially available PCR (Amplicor) was used to test 350 cervical specimens from women in the West African island nation of Cape Verde. The in-house PCR detected 17 cases of N. gonorrhoeae infection, while the Amplicor system detected 14 cases of N. gonorrhoeae infection. No specimen was negative by the in-house PCR assay and positive by the Amplicor PCR. This sensitive nested PCR assay, combined with air-dried storage, allows for the detection of gonococci when specimen storage and transport times are extended and freezing conditions are not available.

Abstract
The prevalence of antenatal risk factors and their association with adverse pregnancy outcome were prospectively studied in the county of Praia, Cape Verde. Of 4693 women registering for antenatal care, 8% were randomly selected from October 1991 through December 1992. Eventually 358 women were observed until puerperium when a physical examination and a structured interview took place. Three out of four women of the cohort were exposed to risk factors according to the existing risk classification in Praia, and 9% presented high risk factors. Thirty two percent of the cohort faced adverse pregnancy outcomes. Adverse pregnancy outcomes were significantly increased among women who presented high risk factors, but 82% of all adverse outcomes occurred among other women. The antenatal risk classification investigated cannot be considered an effective tool for detection of women at risk of adverse pregnancy outcome.

Abstract
BACKGROUND Fifteen years after the implementation of an antenatal risk screening program in Cape Verde, the first assessment of an association between maternal obstetric characteristics and preterm birth or low birthweight (LBW) infants was undertaken. METHODS A cohort of 353 systematically selected antenatal clinic attenders in the county of Praia, Cape Verde, was studied prospectively during the period October 1991 through December 1992. The cohort was followed past the perinatal period and information was obtained according to a pretested structured questionnaire. In the analysis of preterm birth and LBW, multiple logistic regression was listed to estimate the relative risks of ll background variables. RESULTS The prevalence of preterm birth (<37 gestational weeks) was 12%, and the prevalence of LBW infants was 8%. Low birthweight (<2500 grams) was significantly associated with low maternal age (< or = 19 years, RR=3.7); nulliparity (RR=5.2) and obstetric history of previous LBW infant (RR-6.5). The risk of preterm birth was significantly increased if the woman had an obstetric history of hypertension or convulsions (RR=2.6). CONCLUSIONS In the setting studied, teenage women and women with previous pregnancy hypertension should be given selective attention in antenatal care to achieve improved pregnancy outcome. Primary prevention is needed to lower the prevalence of teenage pregnancies.

Abstract
A 45-year-old chemical worker (exposure to vinyl chloride: 500-1612 mg VC/m3 over 248 months) fell ill with a haemangiosarcoma of the liver. This is the first case observed in workers exposed to VC in East Germany. We did not succeed in making the definite histological diagnosis until after the patient's death. The first pathological findings were revealed through the increase in the gamma glutamyl transpeptidase, through sonography and computer tomography of the liver. Numerous tumor biopsies produced either no material or healthy liver tissue, which led to difficulties in therapy. The only chance of effective treatment is an early liver transplantation.

Abstract
19% of the male and 49% of the female AKR mice with spontaneously developed lymphomas show an involvement of the central nervous system (CNS) in the form of a tumor cell infiltration of the leptomeninx. A significantly higher rate of lymphomas was achieved by syngeneic transplantation of lymphoma cells (intraperitoneal inoculation) in the CNS with 87% in both sexes. Morphologically, there were no differences between the leptomeningeal infiltrations in spontaneously developed and transplanted lymphomas. Spontaneous and induced lymphomas of the AKR mouse may be suitable as a simple model for investigations on CNS lymphomas in experimental oncology.

Abstract
Hodgkin's disease is relatively rare in children. The lymph node biopsies of 66 children with Hodgkin's disease were reclassified and discussed in relation to age and sex. The youngest patient was a 2-year-old boy. Mixed cellularity was the most common histologic type (37.9%-25 cases) showing a slight preponderance of boys (14 cases). Nodular sclerosis comprised 31.8% (21 cases) and the lymphocyte predominant type was found in 19.7% (13 cases) in contrast to the low incidence of the lymphocyte depletion type (6.1%-4 cases). At the age of 2 to 10 years Hodgkin's disease prevailed in boys. Our results are discussed regarding the findings of the literature.

Abstract
A 66-year-old female patient complained of loss of body weight and fatigue. The clinical examination revealed a thrombocytosis with a maximum count of 3.200 . 10(9) platelets and a leukocytosis with maximally 25 . 10(9) white cells in the peripheral blood. The bone marrow showed a large increase of megakaryocytes. Under the diagnosis of megakaryocytic myelosis a chemotherapy with 186 mg busulfan was performed. In the course of this treatment the clinical picture of a sepsis occurred which could not be controlled by antibiotics. The patient died four months after her admission to the clinic. The essential findings in autopsy were a caseous tuberculosis of the lymph nodes with haematogenic generalization which appeared as a septic tuberculosa gravissima ("typhobacillosis" Landouzy). The bone marrow was atrophic. Spleen liver and lymph nodes were without evidence for a myeloproliferative disorder. Thus, the initial diagnosis had to be changed to a megakaryocytic pseudomyelosis with massive thrombocytosis as a reaction to the tuberculous infection. The differential diagnosis of megakaryocytic myelosis, other disorders of the myeloproliferative syndrome, and the reactive thrombocytosis are discussed.

Abstract
The value of the Kiel classification of non-Hodgkin's lymphomas (NHL) in neuro-oncology is supported by a systematic prospective study of the CNS in 131 autopsies with NHL. In 31 (23.7%) cases the CNS was involved, mainly in lymphoblastomas (11) and immunocytomas (10). Tumour manifestations of the CNS were found in 17 (20%) out of 84 low grade and 13 (34%) high grade malignant NHL. In plasmocytomas of the bone marrow the CNS was rarely affected. As only one fourth of the CNS infiltrations in lymphomas showed naked-eye appearances, a careful histologic examination of the brain, spinal cord, nerve roots and spinal ganglia, respectively, is necessary for evaluation of the CNS involvement in NHL. The cause of the different incidence of CNS manifestation in various types of NHL is obscure. Further investigations including immunologic, clinical and therapeutic studies have to be carried out for solving this problem.

Abstract
A case of 75 year-old man is reported, who died of a tuberculous leptomeningomyeloencephalitis complicating a generalized primary lymph node plasmacytoma. The malignant lymphoma has been diagnosed in a lymph node biopsy from the right supraclavicular region seven years before the death and was treated with cytostatics over a period of four and a half months. Autopsy revealed the neoplastic involvement of supraclavicular and axillary lymph nodes, tumour infiltration of the sternum and diffuse neoplastic plasmacytosis of the bone marrow. The lymph node plasmacytoma has to be differentiated from reactive lymph node plasmacytosis, angioimmunoblastic lymphadenopathy with excessive plasmacytosis, lymphoplasmacytic immunocytoma, metastasis of an extramedullary plasmacytoma or of a multiple myeloma, and from a lymph node involved by plasma-cell leukemia.

Abstract
The clinical and post-mortem findings in a 59-year-old female patient with an anomalous origin of the left coronary artery are described. This case in the age over fifty is the fourth to be published. The clinical picture was characterized as an antero-lateral myocardial infarction with disturbances of the conduction and with a mitral insufficiency. At autopsy fibrotic areas resulting from myocardial infarction were found in the ventricular septum and in the anterior as well in the posterior muscular wall of the heart. The histological alterations of the arterial wall suggested that the function of the central part of the left coronary artery was that of a vene, while the peripheral parts served as arterio-venous anastomoses. The occurrence of this anomaly in our autopsy material was 0.1 0/00. The pathophysiology is discussed.
