The aim of this study was to investigate hyperacusis measurement tools and to assess the correlation between diagnostic methods for hyperacusis in daily ENT practice. We studied two hyperacusis questionnaires: the Hyperacusis Questionnaire (HQ) and the Multiple-Activity Scale for Hyperacusis (MASH), audiometric measurements (uncomfortable loudness level (ULL) and dynamic range (DR)), and the questions 'Do you have a lower tolerance for noise... ?' and 'Are you afraid of noise?' Hyperacusis was assessed in 46 patients presenting with primary complaints of tinnitus. A validated Dutch version of the HQ is provided. A correlation was found between scores on the HQ and the MASH (p=0.000, R(2)=0.34). Significantly higher scores for both questionnaires were found in patients reporting decreased sound tolerance (p=0.000 and 0.002, respectively) or fear of noise (p=0.002 and 0.004, respectively). Overall, no correlations were found between scores on questionnaires and audiometric values including ULL and DR. The HQ and MASH were confirmed to be valid measurement tools for hyperacusis complaints. No correlations were found between audiometric measurements and hyperacusis complaints.

PurposeAdductor longus injuries are complex. The conflict between views in the recent literature and various nineteenth-century anatomy books regarding symphyseal and perisymphyseal anatomy can lead to difficulties in MRI interpretation and treatment decisions. The aim of the study is to systematically investigate the pyramidalis muscle and its anatomical connections with adductor longus and rectus abdominis, to elucidate injury patterns occurring with adductor avulsions.MethodsA layered dissection of the soft tissues of the anterior symphyseal area was performed on seven fresh-frozen male cadavers. The dimensions of the pyramidalis muscle were measured and anatomical connections with adductor longus, rectus abdominis and aponeuroses examined.ResultsThe pyramidalis is the only abdominal muscle anterior to the pubic bone and was found bilaterally in all specimens. It arises from the pubic crest and anterior pubic ligament and attaches to the linea alba on the medial border. The proximal adductor longus attaches to the pubic crest and anterior pubic ligament. The anterior pubic ligament is also a fascial anchor point connecting the lower anterior abdominal aponeurosis and fascia lata. The rectus abdominis, however, is not attached to the adductor longus; its lateral tendon attaches to the cranial border of the pubis; and its slender internal tendon attaches inferiorly to the symphysis with fascia lata and gracilis.ConclusionThe study demonstrates a strong direct connection between the pyramidalis muscle and adductor longus tendon via the anterior pubic ligament, and it introduces the new anatomical concept of the pyramidalis–anterior pubic ligament–adductor longus complex (PLAC). Knowledge of these anatomical relationships should be employed to aid in image interpretation and treatment planning with proximal adductor avulsions. In particular, MRI imaging should be employed for all proximal adductor longus avulsions to assess the integrity of the PLAC.

A 31-year-old West-African female attended our emergency department presenting with palpitations, headache, fatigue and night sweats during the last 2 weeks. Clinical examination revealed tachycardia and a painful, palpable infraumbilical mass. Ultrasound examination of the abdomen showed a smoothly rounded soft-tissue mass with a diameter of 5 cm. On contrast-enhanced CT, a prevertebral mass with intense contrast enhancement was seen, located caudal to the aortic bifurcation. On PET-CT, there were no distant 18F-FDG-avid locoregional nodes or masses. A tumourectomy was successfully performed, during which manipulation of the retroperitoneal tumour triggered a sharp rise in blood pressure. Histological analysis confirmed the diagnosis of a paraganglioma. The clinical complaints of headache, paroxysmal palpitations and night sweats disappeared postoperatively. This case is a classic presentation of a paraganglioma occurring in the organs of Zuckerkandl, a collection of paraganglia. The diagnosis should be suspected in the presence of a heterogeneous, hypervascular mass in the retroperitoneum and typical clinical symptoms of hypertension, headache and palpitations. Treatment involves surgical resection, after accurate preoperative management. Genetic counselling is required, allowing a personal and genotype-based follow-up.
