Postoncological lacrimal duct reconstruction: A practical classification system for reconstructive planning and short-term results of a case series.

Background: Surgical resection of skin tumors in the medial canthal area may damage the lacrimal duct and can result in chronic epiphora. Postoncologic reconstruction of the lacrimal duct has not been studied extensively. The current study discusses the anatomical and functional features of the lacrimal duct.

[A long-standing swelling on the shoulder].

We present a 49-year-old woman with a cutaneous horn on the right shoulder since 20 years. Cutaneous horn is a clinical diagnosis referring to a benign or malignant lesion of the skin with a conical projection of cornified material. It is most common on sun-exposed skin.

Are routine preoperative liver function tests in patients with uncomplicated symptomatic gallstone disease necessary?

Background: The aim of this study was to evaluate the value of preoperative liver function tests (LFTs) in patients with uncomplicated gallstone disease and scheduled for laparoscopic cholecystectomy.

Methods: All 1112 patients who underwent a laparoscopic cholecystectomy for symptomatic gallstone disease during a 6-year cohort were retrospectively reviewed. Only patients who presented with uncomplicated disease were selected.

The Development of the Cleft Aesthetic Rating Scale: A New Rating Scale for the Assessment of Nasolabial Appearance in Complete Unilateral Cleft Lip and Palate Patients.

Objective: The development of the Cleft Aesthetic Rating Scale, a simple and reliable photographic reference scale for the assessment of nasolabial appearance in complete unilateral cleft lip and palate patients.

Design: A blind retrospective analysis of photographs of cleft lip and palate patients was performed with this new rating scale.

Setting: VU Medical Center Amsterdam and the Academic Center for Dentistry of Amsterdam.

Validation of volume measurements for fetal echocardiography using four-dimensional ultrasound imaging and spatiotemporal image correlation.

Objectives: To assess the accuracy and reliability of four-dimensional (4D) ultrasound imaging using spatiotemporal image correlation (STIC) employing three different techniques to measure volumes in vitro.

Methods: Customized miniature balloons attached to a pump system were used to mimic fetal cardiac chambers. After the balloon model had been immersed in a bath filled with viscous gel, 4D datasets were acquired and three methods were used for volume analysis: three dimensional (3D) slice method, Virtual Organ Computer-aided AnaLysis (VOCAL) and VOCAL combined with inversion mode.
