["Kids Save Lives"-resuscitation training for schoolchildren : Systematic review]. / "Kids Save Lives" ­ Wiederbelebungstrainings für Schulkinder : Systematische Übersichtsarbeit.

BACKGROUND: Even in western developed countries, the probability of survival after out-of-hospital cardiac arrest (OHCA) is only 6-10%. In order to improve survival after OHCA, early initiation of cardiopulmonary resuscitation (CPR) by laypersons is essential. Introduction of CPR training in schoolchildren seems to be effective to increase lay-CPR rates. OBJECTIVE: The objective of the present investigation was to elucidate educational aspects of teaching schoolchildren in CPR and to summarize campaigns related to a comprehensive establishment of lay-CPR worldwide. MATERIALS AND METHODS: A literature research in PubMed was performed, the cutoff date was 27 February 2017. Overall, 192 abstracts were analyzed; 51 articles were considered relevant and included in the manuscript. An additional keyword research in Google revealed >230,000 entries, and 20 of those were included in the present manuscript. RESULTS: A minimum age of 12-13 years is required to achieve a comparable quality of CPR to adult basic life support (BLS). Key issues are (i) the correct detection of a cardiac arrest, (ii) a correctly performed call for help, (iii) thoracic compressions and (iv) if applicable, the initiation of adequate mouth-to-mouth ventilation. Practical training showed a significantly higher CPR quality compared to theoretical training only or to the use of instruction or online videos only. Worldwide implementation of a 2-h BLS training per year in children from the age of 12 or younger is recommended by the "Kids Save Lives"- statement since 2015. In Germany, implementation at the level of the federal states has progressed to different degrees.

The use of ultrasonography in the diagnosis of calculous gallbladder disease.

During a 12-month period from September 1976 to September 1977, 114 patients in a community hospital had ultrasonography as part of their diagnostic work-up for suspected gallbladder disease. While 65 per cent had an additional study, such as an oral cholecystogram or intravenous cholangiogram, 35 per cent had ultrasonography as the only study to make the diagnosis. All patients in this group had laparotomy and cholecystectomy to confirm or disprove the diagnosis of calculous gallbladder disease. The overall accuracy rate of ultrasonography for calculous gallbladder disease was 90 per cent, which compares favorably with the standard oral cholecystogram. Ultrasonography has some distinct advantages in certain clinical situations such as acute cholecystitis, jaundice, pancreatitis and pregnancy. A review of our clinical experience in the everyday use of ultrasonography for calculous biliary disease has been discussed, and guidelines for the use of ultrasonography as part of the diagnostic armamentarium for gallbladder disease are presented.

A direct approach to the more severely deformed cleft lip nose.

Extending the external incision onto the external aspect of the cleft lip nose directly exposes the tip cartilages, which can then be completely elevated, repositioned, and reshaped. The expanded skin allows redraping to the desired contour.

Trabecular or Merkel-cell carcinoma of the skin.

The Merkel-cell tumor (trabecular carcinoma) is an unusual skin appendage malignancy that often recurs locally after initial excision. Occasional regional node metastasis occurs with the larger lesions. This report details our experience with six patients who developed this lesion. Illustrated is a spectrum of malignancy from a locally limited tumor to ones that led to death of the patients. Recognition of this rare tumor is important to ensure proper local treatment with close follow-up observation of the patient.

Heel coverage by a plantar myocutaneous island pedicle flap.

Defects of the heel represent a difficult reconstructive problem. Previously described methods have not always been ideal especially for the posterior heel. The weight-bearing functional requirements of the heel tissue over the calcaneus are a sensitive, well padded, durable cover. The technique of choice should provide local similar tissue plus involve a single reliable operative procedure. Skin grafts placed on the calcaneus or on a muscle transposition flap, such as the flexor digitorum brevis, abductor hallucis, or abductor digiti minimi muscle, provide a thin, insensitive, and dissimilar surface. The cross-foot, cross-leg, cross-thigh, and buttock flaps provide more bulk and thicker skin. These flaps involve a prolonged hospitalization, multiple procedures, increased morbidity, and insensitive tissue. The dorsal foot island flap and microvascular free flaps are a one-stage procedure with less morbidity. The donor tissue is still too dissimilar to provide the protection and durability to this area. Random plantar flaps have provided a functional replacement with similar tissue having adequate sensation. However, these random flaps are not always reliable, have limited motion, and are limited usually to small defects. Recently the myocutaneous flap has been proposed using the flexor digitorum brevis muscle. This neurovascularized flap is larger and more reliable. Our dissection study of plantar tissue using microlatex injected feet has expanded the plantar flap for easier heel coverage and provided a predictable flap area. By mobilizing the pedicle proximally to the posterior tibial artery, the flap has an expanded coverage arc. Thus the heel is covered with a sensitive and durable tissue to allow weight bearing, frictional trauma, and ambulation.
