Atypical Abnormal Pulmonary Vein Drainage with Atrial Septal Defect: Surgical Treatment

Sinus venosus atrial septal defect (SV‐ASD) usually coexists with partial anomalous pulmonary vein connection (PAPVC). It is a difficult diagnosis in transthoracic echocardiography (TTE) due to eccentric position of defects. We present a rare case of atypical anatomical variation in PAPVC, which was never described before. Two right pulmonary veins drained into superior vena cava, which overrode SV‐ASD and interatrial septum, a third pulmonary vein into the right atrium. Complete diagnosis could not be set after TTE, nor transesophageal echocardiography, whereas angio‐CT was finally conclusive. This diagnostic approach allowed the surgical planning.     

A comparative study of angiogenic and cytokine responses after laparoscopic cholecystectomy performed with standard- and low-pressure pneumoperitoneum

Background  Surgical procedures enhance production of pro- and anti-inflammatory cytokines and angiogenic factors that play a pivotal role in the immunological response to surgical trauma and take part in the pathogenesis of tumor growth and adhesions formation. The purpose of the study was to access the influence of low-pressure CO₂ pneumoperitoneum on the inflammatory and angiogenic responses during the postoperative period after laparoscopy. Methods  The study group consisted of 40 patients, operated on due to cholelithiasis using standard-pressure (n = 20) and low-pressure (n = 20) CO₂ pneumoperitoneum. Serum concentration of interleukin (IL)-6, IL-8, IL-10, vascular endothelial growth factor (VEGF)-A, and endostatin were measured before and at 6, 24, and 48 h after surgery with commercially available enzyme-linked immunosorbent assay (ELISA). Results  Concentrations of IL-6 increased significantly after the operations in both groups. No differences were observed between the groups in regards to IL-6, IL-8, and IL-10 levels. Concentrations of VEGF-A measured at 6 and 48 h were significantly lower in patients who underwent laparoscopies performed with low-pressure pneumoperitoneum. No significant variations were observed in endostatin serum concentration. Concentrations of the studied parameters were not influenced by duration of surgery or by age, gender, or body mass index (BMI) of the patients. Conclusions  The results obtained in our study do not show any significant differences between studied operative procedures with regards to systemic inflammatory response. Changes in the concentrations of VEGF-A and endostatin observed in the studied population may suggest this technique is more favorable with regards to angiogenesis process intensity, along with all its consequences and implications.     

Experiences with psychotherapy for depression in routine care: a naturalistic patient survey in Germany

The present survey assessed consumer satisfaction of patients having undergone psychotherapy for depression as well as service characteristics including treatment access, communication of diagnosis and treatment rationale, quality assurance and adverse events. The study was conducted in the form of a 15‐item questionnaire that was published in one of Germany's leading health magazines. 473 persons responded (81.5% women, age range 17–83). 49.8% of the respondents reported substantial or reasonable improvement; two out of three patients stated they had been satisfied with their therapy. Improvement and satisfaction were greater in those patients who had been informed about diagnosis and treatment; they were lower when unpleasant experiences were reported. Methodological restrictions of the study are outlined and hypotheses about potential strengths and deficits in the delivery of psychotherapy for depression in Germany are proposed.

Aortic pulse wave velocity and carotid-femoral pulse wave velocity: similarities and discrepancies.

The objectives of this study were to determine the relationship between carotid-femoral (cfPWV) and aortic pulse wave velocity (aPWV) and to compare their modulators and association with coronary artery disease (CAD). We studied 107 consecutive patients (68 men) with a mean age of 60.49+/-8.31 years who had stable angina and had been referred for coronary angiography. cfPWV and aPWV were measured simultaneously during cardiac catheterization using the Complior device and aortic pressure waveform recordings, respectively. Based on the presence or absence of significant coronary artery stenosis (CAS) patients were subdivided into a CAS+ or CAS- group. The mean values of cfPWV and aPWV were 10.65+/-2.29 m/s and 8.78+/-2.24 m/s, respectively. They were significantly higher in the CAS+ (n=71) compared with the CAS- (n=36) group and predicted significant CAS independently of cardiovascular risk factors and mean or systolic aortic blood pressure. aPWV and cfPWV were significantly correlated (r=0.70; p<0.001) but the degree of correlation differed significantly (p<0.03) between the CAS+ (r=0.74, p<0.001) and CAS- group (r=0.46, p=0.003). Age and mean aortic blood pressure were independent predictors for aPWV as well as cfPWV. In the receiver operating characteristic (ROC) analysis, aPWV and cfPWV had similar accuracy in identification of significant CAS (AUC [area under the ROC curve]=0.76 and 0.69, respectively; p=0.13). However, neither cfPWV nor aPWV was effective at differentiating the extent of CAD. In conclusion, aPWV and cfPWV are highly correlated parameters with similar determinants and comparable accuracy in predicting significant CAS. The strength of correlation between these two indices differed significantly between subjects with and those without CAS.     

Characterization of Cl-/HCO3- exchange in cultured bovine pigmented ciliary epithelium

Many recent data indicate that transport of Cl- across the ciliary epithelium plays an important role in aqueous humor formation. We used 36Cl to investigate the pathways for Cl- transport in confluent monolayers of cultured bovine pigmented ciliary epithelial cells. Cl- uptake mainly occurred via a mechanism with typical characteristics of an anion exchanger, and could be stimulated by an outwardly directed HCO3- gradient. One mM SITS and 1 mM DIDS inhibited Cl- uptake by some 80-90%, the latter with an IC50 of about 20 microM. HCO3- stimulated Cl- uptake could be partly inhibited for furosemide and to a lesser extent by bumetanide, indicating an action of loop-diuretics on the anion exchanger. 36Cl- uptake was cis-inhibited by the halides Cl-, I- and Br-, by NO3-, formate and acetate. Inhibition of Cl- uptake by extracellular HCO3- was less effective in the absence of extracellular Na+, suggesting that not only HCO3- but also NaCO3- binds to the carrier. SO2/4-, cyclamate and gluconate did not significantly reduce Cl- uptake via the anion exchanger. DIDS-senstive Cl- uptake showed saturation kinetics with respect to the Cl- concentration with an apparent Km of 8 mM. Cl- efflux could be stimulated by external Cl- and HCO3- and was inhibited by DIDS. Thus, cultured bovine pigmented ciliary epithelial cells express a Cl-/HCO3- exchanger. A possible role of this carrier system for aqueous humor formation is discussed [corrected].     

Arthroscopic verification of meniscus repair]

The purpose of this study was to verify the arthroscopic meniscus repair by second-look arthroscopy. From November 2001 to October 2005, 28 meniscus (18 medial and 10 lateral) were repaired in 26 patients (two patients had both menisci in one knee repaired). There were 11 females and 15 males. The average age at surgery was 25.5 (range, 13 to 52 years of age). The indication for repair was a full-thickness, vertical tear > or = 8 mm. Meniscus repair was combined with partial meniscectomy of posterior horn because of horizontal tear in 3 cases. In 1 zone 14 meniscus were injured and in 2 zone--also 14 meniscus, according to Cooper's classification. All patients had anterior cruciate ligament rupture. The average time interval between the injury and the repair was 22 weeks (range, 2 weeks to 2 years). The inside-out suture was used in 18 repairs, all inside--3 repairs, outside-in--2 repairs and a mixed technique--5 repairs. Arthroscopic evaluation of meniscus repair was performed on average after 15 weeks (range, 2 months to 37 weeks) since the suture. That was done during the second stage of treatment--ACL reconstruction. There were 78.6% of completely healed repairs, 10.7% of incompletely healed and 10.7% were not healed.     

Grenzen und Möglichkeiten der Glaskörperchirurgie bei diabetischer Retinopathie

Hintergrund: Verschiedene Indikationen für glask?rperchirurgische Eingriffe bei Komplikationen der diabetischen Retinopathie haben sich etabliert. Jedoch gibt es wenig Daten zu der Frage, in welchen Situationen auf einen Eingriff wegen aussichtsloser funktioneller Prognose verzichtet werden sollte. Material und Methode: Die Krankengeschichten von 389 Patienten, die zwischen 1990 und 1994 in unserer Klinik wegen Komplikationen der diabetischen Retinopathie vitrektomiert worden sind, wurden retrospektiv analysiert. Die Nachbeobachtung betrug mindestens 6 Monate, im Median 26 Monate. Mit multivariaten, logistischen Regressionsanalysen wurden Faktoren ermittelt, die mit schlechten postoperativen, funktionellen Ergebnissen korrelieren. Ein mathematisches Modell wurde entwickelt, welches die Einsch?tzung der Prognose für verschiedene Ausgangssituationen erlaubt. Ergebnisse: Bei 45 Augen (12%) stieg der postoperative Visus nicht über 1/50. Risikofaktoren waren Ablatio der Makula, Ausdehnung der Ablatio, Rubeosis und Dauer der Visusminderung. ?hnliche Risikofaktoren gelten auch für Revisionsoperationen. Bei einem Auge mit totaler Traktionsablatio von über 6 Monaten Dauer und Rubeosis liegt die berechnete Wahrscheinlichkeit für einen postoperativen Visus über 1/50 lediglich bei 2%. Schlu?folgerungen: Bei totaler Traktionsablatio, insbesondere bei Rubeosis und l?ngerem Bestehen der Ablatio, ist die Prognose extrem schlecht. Auf operative Ma?nahmen sollte hier verzichtet werden.
