S2k Guidelines for Cutaneous Basal Cell Carcinoma - Part 2: Treatment, Prevention and Follow-up.

Basal cell carcinoma (BCC) is the most common malignant tumor among fair-skinned individuals, and its incidence had been steadily rising in the past decades. In order to maintain the highest quality of patient care possible, the German S2k guidelines were updated following a systematic literature search and with the participation of all professional societies and associations involved in the management of the disease. Part 2 addresses issues such as proper risk stratification, the various therapeutic approaches, and prevention as well as follow-up of patients with basal cell carcinoma.

Measuring and Comparing the Cost-Effectiveness of Surgical Care Delivery in Low-Resource Settings: Cleft Lip and Palate as a Model.

Cleft lip and palate (CLP) care is the longest sustained global effort in humanitarian surgical care. However, the relative cost-effectiveness of surgical delivery approaches remains largely unknown. We assessed the cost-effectiveness of two strategies of CLP surgical care delivery in low resource settings: medical mission and comprehensive care center. We evaluated the medical records and costs for 17 India-based medical missions and a Comprehensive Cleft Care Center in Guwahati, India, from Operation Smile, a humanitarian nongovernmental organization. Age, sex, diagnosis, and procedures were extracted and cost/Disability-Adjusted Life Year (DALY) averted was calculated using a provider's perspective. The disability weights for CLP from the Global Burden of Disease (GBD) 2010 update were used as the reference case. Sensitivity analysis was performed using various disability weights, age-weighting, discounting, and cost perspective. The medical missions treated 3503 patients for first-time cleft procedures and averted 6.00 DALYs per intervention with a cost-effectiveness of $247.42/DALY. The care center cohort included 2778 patients with first-time operations for CLP and averted a mean of 5.96 DALYs per intervention with a cost-effectiveness of $189.81/DALY. The Incremental Cost-Effectiveness Ratio (ICER) of choosing medical mission over care center is $462.55. The care center provides cleft care with a higher cost-effectiveness, although both models are highly cost-effective in India, in accordance with WHO guidelines. Compared to other global health interventions, cleft care is very cost-effective and investment in cleft surgery might be realistic and achievable in similar resource-constrained environments.

Percentile-based assessment of craniosynostosis.

Perioperative assessment of craniosynostosis is based mostly on subjective scores. In this study, we sought to find an objective method to assess cranial deformation based on normative craniofacial percentiles. Anthropometric datasets from 104 (79 males, 25 females) patients with craniosynostoses were included. Anthropometric data were compared with normative age-dependent percentiles. Deviations above the 90th or below the 10th percentile were defined as significant cranial deformation. The cohort comprised 69 children with sagittal, 22 metopic, nine coronal, two bicoronal, one lambdoid, and one with coronal + lambdoid craniosynostosis. Most children with sagittal synostosis were above the 90th percentile for cranial circumference and length, whereas only 27.9% were below the 10th percentile for cranial width. Most (83%) children with scaphocephaly had cranial indices below the 10th percentile. For trigonocephaly, we found normal cranial circumference values in most patients (10th-90th percentile), 40.9% were above the 90th percentile for cranial length, and 63.1% and 57.9% were above the 90th percentiles for sagittal and transverse circumferences. For unicoronal synostosis transverse circumference was above the 90th percentile in 83.3% of children. Matching of anthropometric data of craniosynostosis patients with craniofacial norms could be useful in grading the clinical picture and potentially adapting the operative procedure.

Accuracy of photographic assessment compared with standard anthropometric measurements in nonsynostotic cranial deformities.

OBJECTIVE: Anthropometric landmarks of the skull have traditionally been used to describe cranial deformities resulting from nonsynostotic plagiocephaly or brachycephaly. Recently, digital photography has become an important tool for characterizing facial and cranial pathologies. The purpose of this study was to compare standard anthropometric cranial measurements with measurements taken from cranial photographs. PATIENTS: Standardized digital images in the supracranial view and cranial anthropometric measurements were obtained from 122 children between the ages of 3 and 15 months. The photographs were assessed using Quick Ceph® software. The cephalic index and cranial vault asymmetry index were used to indicate the degree of cranial deformity. Children were classified into plagiocephaly, brachycephaly, and the combination of both. To determine interobserver variability, two clinicians separately measured the cephalic index and cranial vault asymmetry index from digital photographs in 70 infants of the plagiocephalic group. RESULTS: To compare interassay reliability for these methods of obtaining the cephalic index and cranial vault asymmetry index, the differences between photographically and anthropometrically derived values were plotted against anthropometrically derived values alone (Bland-Altman plots). The photographic method satisfied the limits of agreement (cephalic index, 7.51%; cranial vault asymmetry index, 6.57%) and showed slightly lower values represented by the respective bias (cephalic index, 1.79%; cranial vault asymmetry index, 3.03%). Comparison between observers revealed excellent agreement, detected by the intraclass correlation coefficient of .982 for the cephalic index and .946 for the cranial vault asymmetry index. CONCLUSION: Our results demonstrate that digital photography is a reliable tool for quantifying cranial deformities. Furthermore, it is rapid, noninvasive, and reproducible. However, we continue to use both methods in clinical practice.

Retrospective analysis of autologous blood use in bimaxillary repositioning osteotomy surgery: a quality improvement study.

BACKGROUND: Multiple studies have considered the necessity of preoperative autologous blood donation before bimaxillary orthognathic osteotomies. In the context of a quality improvement project, this topic was also investigated in our institution. Furthermore, the transfusion practice was analyzed and the correlations between patient, operative variables, and blood loss were studied. STUDY DESIGN AND METHODS: In accordance with the recommendations of the Federal Medical Association and the Federal Ministry for Health and Social Security, a transfusion demand list was compiled using data of 82 patients who underwent bimaxillary orthognathic surgery between 1997 and 2005. The maximum blood loss tolerable without transfusion (MBL) was calculated for each patient on the basis of sex, weight, height, and preoperative hematocrit (Hct). This was compared with the actual transfusion and blood loss data. RESULTS: An autologous blood donation was carried out in 65 of 82 patients (79.3%). Sixty-two of 65 autologous blood donors (95.4%) and 2 of 17 patients (11.8%) without autologous blood donation received transfusion. The actual blood loss did not exceed the calculated MBL in 48 of the 82 cases. Nevertheless, 31 of these 48 patients (64.6%) received transfusions. For patients with a low calculated MBL, only a trend to a higher transfusion rate was observed, although the actual blood loss in these cases more often exceeded the individually calculated MBL (p < 0.01). In addition, transfusion triggers (Hct 0.22 or hemoglobin 7.5 g/dL) were also more often seen in cases with low calculated MBL (p < 0.05). CONCLUSIONS: In this study, an inappropriate transfusion practice in patients undergoing bimaxillary orthognathic osteotomies after preoperative autologous blood donation was detected. Calculation of the individual MBL should be used to help identify patients at high risk for transfusion and guide adequate methods to decrease the need of homologous blood.
