The KBG syndrome: confirmation of autosomal dominant inheritance and further delineation of the phenotype

We report on a Turkish family in which the father and his two sons were diagnosed as having the KBG syndrome. Large upper central incisors were the diagnostic finding in all three patients along with mental retardation, cryptorchidism, skeletal abnormalities, and short stature. Our report clearly confirms that the inheritance is autosomal dominant in KBG syndrome, although a high male to female ratio has been observed in published cases.     

Primary nephrotic syndrome during childhood in Turkey

BACKGROUND: Minimal change nephrotic syndrome (MCNS) is the most common cause of primary nephrotic syndrome (NS) during childhood. However, recent studies from different countries have reported an increasing incidence of focal segmental glomerulosclerosis (FSGS) in children. METHODS: This is a retrospective study in which 392 Turkish children who were diagnosed with NS during the last 10 years and were followed for at least 2 years, were evaluated. Mean age of the study group was 4.6 +/- 3.4 years (range 0.9-16 years) and 232 were male and 160 were female. RESULTS: In total, 280 patients were diagnosed as MCNS with their initial presentations, laboratory features, and clinical course. Kidney biopsy was performed in the remaining 112 children according to current recommendations. The results showed that membranoproliferative glomerulonephritis (MPGN) was the most common histopathologic diagnosis, 38 (34%) of the 112 patients were found to have MPGN. The number diagnosed as FSGS was 26 (23%). A significant difference was found between the age groups for both MPGN and FSGS, the former being more common in children >6 years of age and the latter more frequent in children 相似文献   

Laparoscopic Anterior Resection: New Anastomosis Technique in a Pig Model

Background and Objectives:

Bowel anastomosis after anterior resection is one of the most difficult tasks to perform during laparoscopic colorectal surgery. This study aims to evaluate a new feasible and safe intracorporeal anastomosis technique after laparoscopic left-sided colon or rectum resection in a pig model.

Methods:

The technique was evaluated in 5 pigs. The OrVil device (Covidien, Mansfield, Massachusetts) was inserted into the anus and advanced proximally to the rectum. A 0.5-cm incision was made in the sigmoid colon, and the 2 sutures attached to its delivery tube were cut. After the delivery tube was evacuated through the anus, the tip of the anvil was removed through the perforation. The sigmoid colon was transected just distal to the perforation with an endoscopic linear stapler. The rectosigmoid segment to be resected was removed through the anus with a grasper, and distal transection was performed. A 25-mm circular stapler was inserted and combined with the anvil, and end-to-side intracorporeal anastomosis was then performed.

Results:

We performed the technique in 5 pigs. Anastomosis required an average of 12 minutes. We observed that the proximal and distal donuts were completely removed in all pigs. No anastomotic air leakage was observed in any of the animals.

Conclusion:

This study shows the efficacy and safety of intracorporeal anastomosis with the OrVil device after laparoscopic anterior resection.     

Adherence to transition guidelines in European paediatric nephrology units

Background

There is increasing focus on the problems involved in the transition and transfer of young adult patients from paediatric to adult renal units. This situation was addressed by the 2011 International Pediatric Nephrology Association/International Society of Nephrology (IPNA/ISN) Consensus Statement on transition.

Methods

We performed a survey of transition practices of 15 paediatric nephrology units across Europe 2 years after publication of the consensus statement.

Results

Two thirds of units were aware of the guidelines, and one third had integrated them into their transition practice. Forty-seven per cent of units transfer five or fewer patients with chronic kidney disease (CKD) stage 5 per year to a median of five adult centres, with higher numbers of CKD stages 2–4 patients. Seventy-three per cent of units were required by the hospital or government to transfer patients by a certain age. Eighty per cent of units commenced transition planning after the patient turned 15 years of age and usually within 1–2 years of the compulsory transfer age. Forty-seven per cent of units used a transition or transfer clinic. Prominent barriers to effective transition were patient and parent attachment to the paediatric unit and difficulty in allowing the young person to perform self-care.

Conclusions

Whereas awareness of the consensus statement is suboptimal, it has had some impact on practice. Adult nephrologists receive transferred patients infrequently, and the process of transition is introduced too late by paediatricians. Government- and hospital-driven age-based transfer policies distract focus from the achievement of competencies in self care. Variable use of transition clinics, written patient information and support groups is probably due to economic and human-resource limitations. The consensus statement provides a standard for evolving and evaluating transition policies jointly agreed upon by paediatric and adult units.     

De novo amyloidosis in a renal transplant patient

Systemic AA amyloidosis is a serious complication of many chronic inflammatory disorders and chronic infections. Renal involvement is seen in the majority of the patients and can lead to end‐stage renal disease. Renal transplantation can be performed in these patients; however, amyloidosis can recur in the transplanted kidneys. On the other hand, de novo AA amyloidosis in renal transplant patients has been rarely reported. We report a 17‐yr‐old patient with end‐stage renal disease due to genitourinary anomalies who developed recurrent pyelonephritis after transplantation. Three yr after transplantation, renal biopsy was performed for proteinuria and AA amyloidosis was identified in the renal allograft. Although rare, chronic infections might cause de novo amyloidosis in renal transplant patients. Therefore, amyloidosis should be kept in mind in those types of patients who present with proteinuria.
