Duplicated superficial branch of the radial nerve and brachioradialis muscle belly: prevalence and significance.

BACKGROUND: The superficial branch of the radial nerve (SBRN) is a sensory nerve innervating the dorsoradial part of the hand. It originates in the cubital fossa, runs under the belly of the brachioradialis muscle (BM), emerges from underneath in the distal third of the forearm and continues in the subcutaneous tissue towards the hand. There exist several anatomical variations of its branching and course, including a rare variation of its duplication combined with a duplication of the brachioradialis muscle belly. The aim of this study was to find out the prevalence of this variation on a sample of cadaveric human bodies which has not been reported yet. MATERIALS AND METHODS: We have carefully dissected 208 cadaveric upper limbs (Central European population). All cases of limbs containing the variation of a double SBRN and/or a double BM belly were measured and documented. RESULTS: We have identified 2 cases of a double SBRN combined with a double BM belly (0.96%). Both were present in the right forearm of a male donor and in both cases the nerve was impinged by muscle bundles connecting the 2 muscle bellies together. Moreover, we have encountered 1 case of a double SBRN without a double BM belly (0.48%), i.e. the total prevalence of a double SBRN was 1.44%. CONCLUSIONS: The duplicated SBRN with the duplicated BM is a relatively rare anatomical variation that might cause complications while performing various surgical procedures in the forearm, moreover it might be a rare cause of Wartenberg's syndrome.

Nursing diagnoses (NANDA-I) in hematology-oncology: a Delphi-study.

PURPOSE: To identify NANDA-I diagnoses that are most relevant to hematology-oncology nursing in Europe. METHODS: In a two-round, electronic, quantitative Delphi study, 28 experts from nine European countries assessed the relevance of NANDA-I diagnoses and health problems. FINDINGS: This study identified 64 relevant diagnoses and three health problems. All experts listed 11 diagnoses: "imbalanced nutrition: less than body requirements,""diarrhea,""fatigue,""risk for bleeding,""risk for infection,""impaired oral mucous membrane,""risk for impaired skin integrity,""impaired skin integrity,""hyperthermia,""nausea,""acute pain," and the health problem "pruritis." CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: The "NANDA-I classification 2009-2011" describes, in almost all disease- and treatment-related problems, nursing diagnoses as relevant to the adult patient with hematological malignancy. These diagnoses are therefore recommended.
