[Physical Activity and Obesity - Underlying Mechanisms, Practical Actions].

Individuals with obesity who undergo surgical or pharmacological therapies achieve good results in terms of weight and cardiometabolic risk reduction. It is not uncommon for those affected to equate the extent of weight loss achieved, with long-term treatment success. What is overlooked is that, in addition to obesity, significant weight loss also carries a risk of sarcopenia.

[Paralytic ileus with fatal consequence under psychotropic medication].

In the area of Bielefeld there occurred a striking accumulation of four cases of death as a consequence of a paralytic ileus within a period of two years. All four patients suffered from a psychotic disorder and had taken psychotropic medication for many years. After exclusion of other causes, the anticholinergic effect of the psychotropic medication must be taken as the cause of death.

Perineural spread of salivary duct carcinoma to the internal auditory canal.

Salivary duct carcinomas (SDCs) are high-grade malignant tumors exhibiting aggressive growth with early regional and distant metastasis. We report a case of SDC in a 63-year-old male with early recurrent disease in the cerebellopontine angle (CPA) after total parotidectomy and adjuvant radiotherapy. The tendency of the tumor to recur or metastasize despite radical surgical measures and radiotherapy continues to pose a therapeutic challenge.

[Intratumoral Onyx embolisation in the management of juvenile nasopharyngeal angiofibroma].

Preoperative embolization for the treatment of juvenile nasopharyngeal angiofibroma was successfully accomplished with Onyx by intratumoral puncture for the first time. Extratumoral migration of Onyx particles was not observed, precluding the necessity to inflate the shield balloon. Postinterventional angiography showed complete occlusion of all supporting blood vessels.

[Cervical paravertebral lesion].

We present the case of a 56-year old male patient complaining of occasional shoulder pain and paresthesia in the left hand. Computer tomography and magnetic resonance imaging showed a left cervical lesion. Angiography was normal.

[Direct percutaneous embolization of a carotid body tumor with Onyx].

Carotid body tumors are highly vascularized lesions that require successful preoperative embolization to achieve favorable clinical results in terms of morbidity and complete tumor resection. The procedure of percutaneous embolization was performed using ethylene-vinyl alcohol copolymer (Onyx) in addition to balloon-catheter protection to prevent particle displacement into the internal carotid artery. The procedure resulted in nearly complete tumor embolization and facilitated the uneventful complete surgical resection.

[Hamartoma : a rare nasopharyngeal pathology as a cause of nasal obstruction].

We present a case of a 44-year-old man with complaints of double-sided nasal obstruction and a foreign body sensation. A polypoid lesion was seen in the nasopharynx and was later completely excised. Histologic examination showed a respiratory epithelial adenomatoid hamartoma.

Schwannoma of the larynx.

Objectives: Neurogenic tumors of the larynx are extremely rare. The goal of this report is to advert to this rare disease, to review and discuss diagnostics, differential diagnoses and treatment options.

Study Design: Retrospective case report and review of the literature.

[Heterotopic pancreatic tissue in the bifurcation of the bile duct : Rare diagnosis mimicking a Klatskin tumour].

Heterotopic tissue of the pancreas can be found in 1-2% of autopsies. The main locations are stomach, duodenum, jejunum, Meckel's diverticulum, and ileum. Less frequently it is observed in the liver, gallbladder, common bile duct, and papilla of Vateri.

Quality of life after surgical therapy of bronchogenic carcinoma.

Quality of life (QL) after the "curative" resection of non-small cell bronchogenic carcinoma was assessed by patients using the EORTC QL questionnaire (QLQ) and by a psychologist using the Spitzer Index. Quality of life was assessed in 52 patients on one occasion 12 months postoperatively and in 20 patients regularly starting with a preoperative assessment. Self- and external evaluation showed a significant correlation (r = 0.

[New methods for the morphometric analysis of anisotropic tissues].

Some unbiased, design-based stereological methods that have recently been developed for the study of anisotropic tissues like muscle, myocardium, brain, cartilage, and skin, are briefly reviewed. Vertical sections permit the unbiased estimation of surface density and mean volume-weighted particle volume from microscopic sections. The available experience includes various studies on malignant melanomas.
