Plädoyer für die primäre Resektion mit primärer Anastomose bei der komplizierten Sigmadiverticulitis

Zusammenfassung Von 1973 bis 1986 wurden 107 Patienten mit einer komplizierten Sigmadiverticulitis operiert. Es handelte sich um 47 Frauen und 60 Männer bei einem Durchschnittsalter von 62 Jahren. Von 107 Patienten wiesen 14 eine perforierte Diverticulitis mit diffuser eitriger/kotiger Peritonitis auf, 68 Patienten eine perforierte Diverticulitis mit lokalisierter eitriger Peritonitis/paracolischem Absceß und 25 Patienten eine akute phlegmonöse Diverticulitis ohne Perforation. Zusätzliche pathologische Befunde waren: innere Fisteln (13 Patienten), nekrotisierende Fasciitis (3 Patienten), Stenose mit Ileus (3 Patienten) und synchrone Carcinome (7 Patienten). Die Gesamtletalität der 107 Patienten betrug 9,3% (=10 Patienten), die Morbidität der 97 überlebenden Patienten 34,0% (= 33 Patienten). Die Letalität bei 14 Patienten mit perforierter Diverticulitis und diffuser eitriger/kotiger Peritonitis lag bei 50%, die der 68 Patienten mit perforierter Diverticulitis und lokaler eitriger Peritonitis/ paracolischem Absceß bei 4,4%, die der 25 Patienten mit akuter phlegmonöser Diverticulitis ohne Perforation bei 0%. Von den 10 Patienten verstarben 7 bei Operation ihrer perforierten Diverticulitis mit diffuser eitriger Peritonitis, 1 (5) nach primärer Resektion mit primärer Anastomose, 3 (5) nach Operation nach Hartmann, 3 (4) nach alleiniger Anlage einer Colostomie. Bei Operation der perforierten Diverticulitis mit lokaler Peritonitis verstarben 3 Patienten, 2 (6) nach Operation nach Hartman und 1 (5) nach alleiniger Anlage einer Colostomie. Trotz einer hohen Zunahme der Zahl primärer Resektionen mit primärer Anasto mose im Zeitraum 1980–1986 ergab sich im Vergleich zum 7-Jahresabschnitt 1973–1979 ein Rückgang der Letalität von 35,7% auf 0% bei dieser Operation. Ihre Anwendung ist auch gerechtfertigt bei der perforierten Diverticulitis mit lokaler wie diffus eitriger oder kotiger Peritonitis.

Primary resection with primary anastomosis in complicated diverticulitis of the sigma

Summary Of the 107 patients with complicated diverticulitis operated from 1973–1986 47 were females and 60 males. In 14 of the 107 patients a perforated diverticulitis with diffuse purulent/faecal peritonitis was found, a perforated diverticulitis with localized purulent peritonitis/paracolic abscess in 68 patients and an acute phlegmonous diverticulitis without perforation in 25 patients. Additional pathologic findings were internal fistulae (13 patients), necrotizing fasciitis (3 patients), obstruction (3 patients) and synchronous carcinoma (7 patients). The overall mortality of the 107 patients was 9.3 % (=10 patients) and the morbidity of the 97 survivors 34% (=33 patients). The mortality of the 1.4 patients with perforated diverticulitis and diffuse purulent peritonitis was 50%, of the 68 patients with perforated diverticulitis and localized purulent peritonitis 4.4% and of the 25 patients with acute phlegmonous diverticulitis 0%. Seven of the 10 patients died after operation of the perforated diverticulitis with diffuse purulent peritonitis — 1 (5) after primary resection with primary anastomosis, 3 (5) after Hartmann procedure, 3 (4) after loop colostomy alone. Three patients died after operation of the perforated diverticulitis with localized purulent peritonitis — 2 (6) after Hartmann procedure, 1 (5) after loop colostomy alone. In spite of forcing the primary resection with primary anastomosis in the years from 1980–1986 the mortality decreased for these operations from 35.7% in 1973–1979 to 0% in 1980–1986. The indication of primary resection with primary anas tomosis is justified also for perforated diverticulitis with localized and diffuse peritonitis.

Autoimmune hepatitis type 1 and primary biliary cirrhosis have distinct bone marrow cytokine production

We have recently reported differences in the hematopoiesis between autoimmune hepatitis type 1 (AIH-1) and primary biliary cirrhosis (PBC). In view of the notion that cytokines are regulators of hematopoiesis, we investigated in our tertiary center the cytokine production in the bone marrow (BM) of the same consecutive cohort of patients (13 AIH-1, 13 PBC, 10 healthy and 7 patients with cirrhosis due to chronic hepatitis B). Interferon-gamma (IFN-gamma), interleukin-4 (IL-4), interleukin-10 (IL-10), tumor necrosis factor-alpha (TNF-alpha) and transforming growth factor-beta (TGF-beta) were determined in the supernatants of long-term BM cultures by ELISAs. IL-4, TNF-alpha and TGF-beta were found significantly increased in the BM of PBC patients compared to AIH-1 and both control groups. AIH-1 patients had significantly higher BM IL-10 compared to PBC patients and higher IL-10, IL-4 and TNF-alpha compared to controls. BM IFN-gamma was significantly higher in PBC and AIH-1 patients compared to controls. In AIH-1 patients, IL-10 was positively correlated with CD34+, CD34+/CD38- and CD34+/CD38+ cell proportions. In conclusion, the BM cytokine microenvironment of PBC and AIH-1 patients differs significantly compared to that of healthy individuals and cirrhotic patients of non-autoimmune etiology. Differences were also found between patients with PBC and AH-1. The implication of BM in the pathogenesis of autoimmune liver diseases is possible and needs further investigation.     

Spinothalamic and propriospinal neurones in the upper cervical cord of the rat: terminations of primary afferent fibres on soma and primary dendrites

Summary Experiments were performed on rats to determine whether primary afferents from the upper cervical region terminate directly on Spinothalamic and propriospinal neurones. The central terminations of primary afferents from the upper cervical region were identified by diffusely filling their axons with horseradish peroxidase. Spinothalamic neurones or propriospinal neurones were identified in the same experimental animals by using retrograde transport of wheat germ agglutinin conjugated to horseradish peroxidase. Approximately 3–11 % of Spinothalamic cells in laminae 4–6 of spinal segments C2–4 received apparent synaptic contacts from primary afferents on the soma or primary dendrites. Approximately 18–36% of propriospinal neurones with axons descending to lower thoracic or lumbar levels received apparent synaptic contacts on the soma or primary dendrites. These data provide anatomical evidence that Spinothalamic and long propriospinal neurones in the upper cervical cord are excited directly by primary afferents. The data also help to clarify the neural circuitry underlying somatic sensation and reflex movements evoked by neck receptors.

Information security concepts and practices: the case of a provincial multi-specialty hospital

In recent years, major and widely accepted information security understandings and achievements confirm that the problem is complex. They clarify that technologies are fundamental tools, but management processes have even bigger relevance, as also prestigious international magazines dossier clearly explained recently. Such a magazine attention outlines the wide impact that the subject has on watchful decision makers. ISO17799 is an emerging standard in information security. In principle there are no reasons for considering it not applicable to the health care sector. In practice, because of both the just conceptual level of the standard and the peculiarities of the health care data and institutions, a lot of analysis and design work need to be invested any time a health care institution decides to deal with the subject. CEN/ENV 12924 is another emerging standard certainly more on the spot of the health care. Nevertheless, it also asks for evident further investigation. The practical case of information security design, implementation, management, and auditing inside a multi-specialty provincial Italian hospital will be described.     

Electronic patient-provider communication: will it offset office visits and telephone consultations in primary care?

BACKGROUND AND AIM: Electronic patient-provider communication promises to improve efficiency and effectiveness of clinical care. This study aims to explore whether a secure web-based messaging system is an effective way of providing patient care in general practices. METHOD: We conducted a randomised controlled trail and recruited 200 patients from the waiting area in one primary clinic in Norway. Participants were randomised to either the intervention group, which received access to a secure messaging system, or the control group receiving standard care without such access. Primary outcome measures were number of online consultations, telephone consultations and office visits in the two groups. Data were derived from patient records and collected 1 year prior to (baseline), and 1 year after the intervention. RESULTS: Forty-six percent of the patients who were given access to the messaging system (n=99) used the online communication system on at least one occasion (ranging from 1 to 17 messages per patient per year). A total of 147 electronic messages were sent to six general practitioners during a 1-year trial period. Eleven percent of the messages were to schedule an appointment. In 10% of the messages, the GP was unable to respond adequately and recommended an office visit. The reduction in office visits over time was greater for the intervention group than for the control group (P=0.034). There was however no significant difference in the number of telephone consultations between the groups during the study (P=0.258). CONCLUSION: The use of a secure electronic messaging system reduced the number of office visits at the general practice, but not phone consultations.     

Primary gastric apoptosis-rich T-cell lymphoma co-expressing CD4, CD8, and cytotoxic molecules

In contrast to primary gastric lymphomas of B-cell type, little is known about primary gastric T-cell lymphomas. We describe three cases with remarkably similar features: diffuse growth, epitheliotropism, medium too large cell size, high apoptotic rates, and a CD3+, CD4+, CD8+, CD45RO+ immunophenotype. Clonal TCRγ gene rearrangement was shown in two cases. Epstein-Barr virus infection was excluded in two cases. Taking advantage of fresh-frozen material, we analyzed two cases further, revealing CD5–, CD16+, CD56–, CD57–, CD25+, CD30+, CD103 (αEβ7)+, bcl-2 protein+, CD95+, CD95 ligand(L)–. CD95L, however, was detected in histiocytic and fibroblastoid by stander cells. The lymphomas expressed granzyme B, perforin, and the TIA-1 antigen in various combinations. All three cases had a very unfavorable clinical course characterized by local recurrence and/or dissemination to other epithelial sites, leading to death within 6–12 months after the initial diagnosis despite surgery and aggressive antineoplastic treatment. These data suggest a novel variant of peripheral T-cell lymphoma operationally characterized as primary gastric, apoptosis-rich, CD103+, EBV-, T-cell lymphoma co-expressing CD4, CD8, CD16 and cytotoxic molecules.

Tonic differential supraspinal modulation of PAD and PAH of segmental and ascending intraspinal collaterals of single group I muscle afferents in the cat spinal cord

We compared in the anesthetized cat the effects of reversible spinalization by cold block on primary afferent depolarization (PAD) and primary afferent hyperpolarization (PAH) elicited in pairs of intraspinal collaterals of single group I afferents from the gastrocnemius nerve, one of the pairs ending in the L3 segment, around the Clarkes column nuclei, and the other in the L6 segment within the intermediate zone. PAD in each collateral was estimated by independent computer-controlled measurement of the intraspinal current required to maintain a constant probability of antidromic firing. The results indicate that the segmental and ascending collaterals of individual afferents are subjected to a tonic PAD of descending origin affecting in a differential manner the excitatory and inhibitory actions of cutaneous and joint afferents on the pathways mediating the PAD of group I fibers. The PAD-mediating networks appear to function as distributed systems whose output will be determined by the balance of the segmental and supraspinal influences received at that moment. It is suggested that the descending differential modulation of PAD enables the intraspinal arborizations of the muscle afferents to function as dynamic systems, in which information transmitted to segmental reflex pathways and to Clarkes column neurons by common sources can be decoupled by sensory and descending inputs, and funneled to specific targets according to the motor tasks to be performed.     

Primary Immunodeficiency Syndrome in Spain: First Report of the National Registry in Children and Adults

The Spanish Registry for Primary Immunodeficiency Diseases (REDIP) was organized in 1993. One thousand sixty-nine cases of primary immunodeficiency diseases (PID) were registered in patients diagnosed between January 1980 and December 1995. PID diagnosis was made according to the World Health Organization criteria. The most frequent disorders were IgA deficiency (n = 394) and common variable immunodeficiency (n = 213), followed by severe combined immunodeficiency (n = 61), C1 inhibitor deficiency (n = 52), X-Iinked agammaglobulinemia (n = 49), IgG subclass deficiency (n = 48), and chronic granulomatous disease (n = 32). A comparative study between REDIP and data recently obtained from the European registry (ESID Report, 1995) revealed important differences between phagocytic disorders and complement deficiencies reported in both registries, 4.9 vs 8.7 and 6.0 vs 3.6, while percentages of predominantly antibody deficiencies and T cell and combined deficiencies concurred with those reported in the European registry, 69.3 vs 64.7 and 14.7 vs 20.2, respectively. The heterogeneous nature of the geographical distribution of cases submitted may indicate underdiagnosis of PID in some country areas; surprisingly, the interval between the onset of clinical symptoms and diagnosis was significant, even in immunodeficiency diseases, such as IgA deficiency, which are easy to diagnose.
