Background: Lymph node (LN) retrieval and assessment is essential for accurate staging and treatment planning in colorectal cancer (CRC). According to U.S. National Cancer Institute recommendations, the minimal number of LNs needed for accurately staging of node-negative CRC is 12. Awareness and implementation of the guidelines has been shown to improve after assigning an opinion leader who has a special interest in CRC.

Objectives: To evaluate the impact of dialogue between surgeons and pathologists in LN evaluation.

Methods: Consecutively treated CRC patients at the Department of Surgery B at Rambam Medical Center from January 1, 2000 through July 30, 2005 were identified from hospital discharge files. Demographic, surgical, and pathological data were extracted. Patients were divided into two groups. Group I patients underwent surgery before the initiation of a structured surgical oncology service (January 1, 2000 to October 30, 2004). Group II patients underwent surgery after the initiation of the service (November 1, 2004 to July 30, 2005).

Results: The study comprised 212 patients (Group I: n=170; Group II: n=42). The median number of LNs examined was 9 in Group I and 14 in Group II (P = 0.003). Only 35% of patients in Group I received adequate LN evaluation compared to 79% in Group II (P = 0.0001). Patients with left-sided or rectal cancer were less likely to receive adequate LN evaluation than patients with right-sided cancers.

Conclusions: A durable improvement in LN evaluation was realized through a multi-pronged change initiative aimed at both surgeons and pathologists.

 Background: Renal tubular dysgenesis is a rare lethal kidney abnormality clinically manifested by olighydramnios, anuria and respiratory distress. Most of the information on this entity is provided by case reports and short series.

Objectives: To evaluate the incidence and comparative frequency of clinical manifestations in different etiologic-pathogenic variants of RTD[1] in Israel and in summarized published data.

Methods: Stillborn and neonatal autopsy material from nine medical centers in northern and central Israel was studied. Information concerning pregnancy, labor and postnatal status and autopsy findings of cases with histologically, histochemically and immunohistochemically confirmed RTD were obtained from corresponding reports and from published material.

Results: From the 1538 autopsies of fetuses (≥ 20 weeks gestation) and neonates that were performed between 1976 and 2007 we identified 12 cases of RTD (0.78%). Abnormality occurred more often (1.4%) in the Upper and Western Galilee than in Israel as a whole.

Conclusions: Our study and a review of the literature showed that the autosomal recessive variant of RTD was more frequent than twin-twin transfusion induced. Most symptoms were similar in all variants of RTD, but their frequency was different in each of them.
