Radial nerve palsy in humeral shaft fractures with internal fixation: analysis of management and outcome.

INTRODUCTION: The incidence of radial nerve injury after humeral shaft fractures is on average 11.8% (Shao et al., J Bone Jt Surg Br 87(12):1647-1652, 2005) representing the most common peripheral nerve injury associated with long bone fractures (Korompilias et al., Injury, 2013). The purpose of this study was to analyze our current policy and long-term outcome, regarding surgically treated humeral shaft fractures in combination with radial nerve palsy. MATERIALS AND METHODS: We retrospectively analyzed the data of patients with surgically treated humeral shaft fractures from 01/01/2003 to 28/02/2013. The analysis included fracture type, soft tissue injury regarding closed and open fractures, type of fixation, management, and outcome of radial nerve palsy. RESULTS: A total of 151 humeral shaft fractures were fixed in our hospital. In 20 (13%) cases, primary radial palsy was observed. Primary nerve exploration was performed in nine cases. Out of the 13 patients with follow-up, 10 showed a complete, 2 a partial, and 1 a minimal nerve recovery. Two of them underwent a revision procedure. Secondary radial nerve palsy occurred in 9 (6%) patients postoperatively. In five patients, the radial nerve was not exposed during the initial surgery and, therefore, underwent revision with nerve exploration. In all 5, a potential cause for the palsy was found and corrected as far as possible with full recovery in 3 and minimal recovery in one patient. In four patients with exposure of the nerve during the initial surgery, no revision was performed. All of these 4 showed a full recovery. CONCLUSION: Our study showed an overall rate of 19% radial nerve palsy in surgically treated humeral shaft fractures. Most of the primary palsies (13%) recovered spontaneously, and therefore, nerve exploration was only exceptionally needed. The incidence of secondary palsy after surgery (6%) was high and mainly seen after plate fixation. In these cases, we recommend early nerve exploration, to detect and treat potential curable neural lesions.

Shorter time since inflammatory bowel disease diagnosis in children is associated with lower mental health in parents.

AIM: This study assessed the mental health of parents of children with inflammatory bowel disease (IBD), compared their mental health with age-matched and gender-matched references and examined parental and child predictors for mental health problems. METHODS: A total of 125 mothers and 106 fathers of 125 children with active and inactive IBD from the Swiss IBD multicentre cohort study were included. Parental mental health was assessed by the Symptom Checklist 27 and child behaviour problems by the Strengths and Difficulties Questionnaire. Child medical data were extracted from hospital records. RESULTS: While the mothers reported lower mental health, the fathers' mental health was similar, or even better, than in age-matched and gender-matched community controls. In both parents, shorter time since the child's diagnosis was associated with poorer mental health. In addition, the presence of their own IBD diagnosis and child behaviour problems predicted maternal mental health problems. CONCLUSIONS: Parents of children with IBD may need professional support when their child is diagnosed, to mitigate distress. This, in turn, may help the child to adjust better to IBD. Particular attention should be paid to mothers who have their own IBD diagnosis and whose children display behaviour problems.

[Bipartite carpal scaphoid with osteonecrosis of the proximal pole - differential diagnosis of pseudarthrosis]. / Os scaphoideum bipartitum mit Osteonekrose des proximalen Anteils - Differenzialdiagnose zur Pseudarthrose.

We report on the case of a young patient with bipartite carpal scaphoid with osteonecrosis of the proximal pole. The important differentiation of this entity to the pseudarthrosis of the scaphoid is discussed.

X-linked inhibitor of apoptosis (XIAP) deficiency: the spectrum of presenting manifestations beyond hemophagocytic lymphohistiocytosis.

X-linked inhibitor of apoptosis (XIAP) deficiency caused by mutations in BIRC4 was initially described in patients with X-linked lymphoproliferative syndrome (XLP) who had no mutations in SH2D1A. In the initial reports, EBV-associated hemophagocytic lymphohistiocytosis (HLH) was the predominant clinical phenotype. Among 25 symptomatic patients diagnosed with XIAP deficiency, we identified 17 patients who initially presented with manifestations other than HLH. These included Crohn-like bowel disease (n=6), severe infectious mononucleosis (n=4), isolated splenomegaly (n=3), uveitis (n=1), periodic fever (n=1), fistulating skin abscesses (n=1) and severe Giardia enteritis (n=1). Subsequent manifestations included celiac-like disease, antibody deficiency, splenomegaly and partial HLH. Screening by flow cytometry identified 14 of 17 patients in our cohort. However, neither genotype nor protein expression nor results from cell death studies were clearly associated with the clinical phenotype. Only mutation analysis can reliably identify affected patients. XIAP deficiency must be considered in a wide range of clinical presentations.

[Glomangiomatosis on the hand. A case report]. / Glomangiomatose der Hand. Ein Fallbericht.

Glomus tumours are solitary benign lesions most frequently located subungually on fingers and toes. In the rare case of a glomangiomatosis, the typical glomus cells are found on the altered vessel wall of the angiomatosis. Due to the rarity of this disease, no therapeutic golden standard has been mentioned in the literature, and a conservative treatment is usually adopted. The case of a 20-year-old craftsman with congenital, painful glomangiomatosis on his left dominant hand, progressively limiting the functionality of this limb, is reported. Two years after unsuccessful partial tumour resection, a surgical treatment based on radical tumour resection in terms of a finger amputation was performed. The 1-year follow-up showed no signs of pain for the patient.

[A young child with acute abdomen and iron deficiency anemia]. / Ein Kleinkind mit akutem Abdomen und Eisenmangelanämie.

The case of a 20 month-old girl that was admitted to the emergency ward because of worsening of her general condition in the setting of acute non-bloody gastroenteritis is reported. The clinical examination revealed signs of severe dehydration and a prominent tender abdomen. Laboratory evaluation showed leucocytosis, elevated C-reactive protein and severe hypochromic microcytic anemia. Abdominal X-ray revealed diffuse meteorism. The child underwent laparascopic evaluation. A perforated Meckel's diverticulum was found. Perforation and anemia due to occult bleeding are unusual presentations of Meckel's diverticulum. The differential diagnosis of children presenting with an acute abdomen with special focus on Meckel's diverticulum is discussed.
