[Diffuse Leptomeningeal Glioneuronal Tumor with Subarachnoid Hemorrhage:A Case Report].

Diffuse leptomeningeal glioneuronal tumor(DLGNT)is a rare primary neoplasm of the central nervous system, and is a condition that is newly listed in the 2016 World Health Organization(WHO)classification of tumors of the central nervous system. We report an adult case of DLGNT that was characteristically merged with subarachnoid hemorrhage. A 46-year-old woman reported persistent dizziness upon walking. MRI of the brain revealed a diffuse, infiltrating lesion with high intensity on FLAIR around the cerebellopontine angle to the lateral ventricle and in the leptomeninges of the spinal cord. The lesion on the cerebellopontine angle showed high intensity on T1 weighted images with contrast enhancement. Since diffuse glioma and meningeal carcinomatosis were suspected, we performed an endoscopic biopsy for the lesion in the right lateral ventricle. Although the tumor was tentatively diagnosed as WHO grade II diffuse astrocytoma, a definitive diagnosis could not be obtained. One month after surgery, the patient presented with acute headache and dizziness. CT showed subarachnoid hemorrhage in the cerebellopontine angle. To decompress the intracranial pressure and prevent re-bleeding, and to obtain enough tissue samples for definitive diagnosis, we removed the enhanced lesion and hematoma at the cerebellopontine angle. Tumor tissue was composed of oligodendroglial-like cells and was positive for GFAP, Olig2, synaptophysin, and S100 protein, although it was negative for IDH1<sup>R132H</sup>. Fluorescent <i>in situ</i> hybridization showed <i>KIAA1566-BRAF</i> fusion; however, neither 1p loss nor 1p19q co-deletion was observed. Together with histological and radiological findings, the tumor was ultimately diagnosed as DLGNT. The patient received maintenance chemotherapy with temozolomide, and the tumor was stable at 18 months after surgery.

Single-center study: dynamic contrast-enhanced ultrasound in the diagnostic assessment of carotid body tumors.

Carotid body tumors (CBTs) depict the most common paraganglioma of the head and neck that can metastasize in up to 15% of cases. They develop either sporadically or hereditarily and may produce catecholamines ("functioning CBTs") resulting in associated symptoms like headache, palpitations or flush. Non-functioning CBTs usually present as slowly and often tender growing mass which may affect adjacent cranial nerves. CBTs can be visualized by ultrasound, CT, MRI or angiography. Pre-surgical interventional embolization, surgical resection and radiation therapy are therapeutical options. The aim of this retrospective single-center study is to assess the safe and real-time evaluation of CBTs by contrast-enhanced ultrasound (CEUS).

Adherence of heart failure patients to heart failure medications and its determinants in the Aseer region, Southern Saudi Arabia.

Heart failure is a complex clinical syndrome of cardiovascular disease. Heart failure occurs when the heart muscle is weakened and cannot pump enough blood to meet the body's needs for blood and oxygen. It is characterised by several attacks of dyspnoea, chest pain, orthopnea and pulmonary or systemic congestion. The heart inability to fulfill the demands of the body further failure of heart to pump the blood with normal efficiency. Lack of patients' adherence to their treatment may affect their clinical compensation.

Haemophilus haemolyticus: an atypical pathogen of septic arthritis of the knee joint.

Septic knee arthritis is a common disease, mostly due to bacterial infections. We describe a rare case of Haemophilus haemolyticus causing unilateral septic arthritis of a native knee. The affected patient presented with persistent severe knee pain after repeated intra-articular injections. Patient history included knee arthroscopy and a known rheumatoid arthritis treated by steroids. Since conservative treatment was ineffective and infection could not be excluded, diagnostic arthroscopy was performed. Synovial fluid and biopsies verified the uncommon microorganism and antibiotic therapy was initiated. Clinical findings and blood results showed rapid improvement. The patient was discharged in a good condition after 6 weeks. A review of the current literature describes only one joint infection with H. haemolyticus as underlying cause. In immunocompromised patients with septic knee arthritis also atypical pathogens must be considered. Nevertheless, the established treatment algorithm with arthroscopy and anti-infective therapy seems to be effective leading to satisfactory results.

A rare penetrating injury through the axilla caused by stilt pole in a Bajau Laut boy.

An 8-year-old child of Bajau Laut descent (a stateless tribe in Eastern Borneo and the Sulu archipelago) presented following a fall, with penetrating injury through the axilla caused by a stilt pole, exiting at the supero-anterior aspect of the left shoulder. Due to the lack of comprehension of modern medical treatment and poor language skills, the parents refused to consent for detailed radioimaging studies, nor surgical removal and exploration in the operating theatre. The removal of retained stilt pole was done in casualty area in Hospital Tawau, followed by local exploration under sedation and local analgesia. Despite the horrific injury, there was no limb-threatening neurovascular injury sustained. Management of such injury in the nomadic Bajau Laut population provides valuable insight and about the challenges and decisions of management.

[The reconstruction of Myerson type Ⅲ chronic Achilles tendon rupture by using the total arthroscopic technique combined with free semitendinosus tendon and gracilis tendon autograft].

To evaluate the clinical outcome of the reconstruction of Myerson type Ⅲ chronic Achilles tendon rupture by using the total arthroscopic technique combined with free semitendinosus tendon and gracilis tendon autograft. Clinical data of 32 patients(32 ankles) with Myerson type Ⅲ chronic Achilles tendon rupture who were treated by using the total arthroscopic technique combined with free semitendinosus tendon and gracilis tendon autograft at Department of Hand and Foot Microsurgery, Xuzhou Central Hospital from September 2013 to September 2018 were analyzed retrospectively.There were 28 males and 4 females, aged 45.5 years old(range: 22 to 69 years old), 12 cases in the right side and 20 in the left.All patients were treated by using the total arthroscopic technique combined with free semitendinosus tendon and gracilis tendon autograft for Myerson type Ⅲ chronic Achilles tendon rupture reconstruction.The functional recovery of the ankle was evaluated according to ankle-hindfood score of American Orthopaedic Foot and Ankle Society (AOFAS) Ankle Hindfoot Scale, Achilles tendon total rupture score (ATRS), visual analogue scale (VAS).Arner-Lindholm score was used to evaluate the excellent and good rate.The quantitative data were compared using -test or Wilcoxon test. The 32 patients were followed up for 33 months (range: 15 to 72 months).No serious postoperative complications such as infection, sural nerve injury or tend re-rupture outcomes were reported.Three patients complained of mild pain when after a minimum sitting, walking or jogging, which were completely relieved by simple physical therapy or continuous stretching of Achilles tendon.At the last follow-up, the VAS decreased from 3 (5) ( (()) ) preoperative to 0 (3) (1.357, 0.01) and AOFAS ankle hindfoot scale improved from 58.6±13.5 preoperative to 95.5±4.0 (16.9, 0.00), ATRS improved from 47.5±9.3 preoperative to 96.6±3.3 (25.661, 0.01).According to the score of Arner-Lindholm, 20 cases were excellent, 12 cases were good, and the excellent and good rate was 100%. The reconstruction of Myerson type Ⅲ chronic Achilles tendon rupture by using the total arthroscopic technique combined with free semitendinosus tendon and gracilis tendon autograft has the advantages of safety, reliability, effectiveness and minor injury.

Chronic pain in patients with hemophilia: is it preventable?

: Current management of chronic pain in patients with hemophilia (PWH) focuses on pain relief with analgesics and symptom control. The clinical practice of managing chronic pain in PWH varies considerably across hemophilia treatment centers. Here, we aim to study the appropriate intervention of hemophilic arthropathy for prevention and treatment of chronic pain in PWH. Medline, Embase, Cochrane databases were searched for randomized controlled trials, and the European Hemophilia Therapy Standardization Board, The World Federation of Hemophilia, Nordic Hemophilia Guidelines, American Society of the International Pain Physicians and the Medical and Scientific Advisory Council guidelines were studied through November 2019 for chronic pain in PWH for a narrative review. We found no standardized approach for the prevention and management of chronic pain in PWH. Evidence suggests that prophylactic factor concentrate therapy, programmed exercise and educational intervention may help PWH manage their chronic pain.
