Late-onset posttraumatic septal hematoma and abscess formation in a six-year-old Tamil girl--case report and literature review

Nasal septal hematoma with abscess (NSHA) is an uncommon complication of trauma and studies on children are especially rare. We discuss the case of a 6-year-old girl, who was initially evaluated independently by three doctors for minor nasal trauma but had to be re-hospitalized 6 days later with NSHA. Although septal hematoma had initially been excluded (5, 7 and 24 hours after trauma), a secondary accumulation of blood seems to have occured. Delayed hematoma formation has been described in the orbit as a result of possible venous injuries after endoscopic sinus surgery. However, such an observation is new for septal hematoma in children. Thus, we recommend re-evaluation for septal hematoma 48h to 72h after paediatric nasal trauma. Such a scheduled re-examination offers a chance to treat delayed subperichondral hematoma on time before almost inevitable superinfection leads to abscess formation and destruction of the nasal infrastructure. We suggest that parents should be vigilant for delayed nasal obstruction as possible herald of hematoma accumulation within the first week.

Clinical presentation of a traumatic cervical spine disc rupture in alpine sports: a case report

ABSTRACT: Isolated non-skeletal injuries of the cervical spine are rare and frequently missed. Different evaluation algorithms for C-spine injuries, such as the Canadian C-spine Rule have been proposed, however with strong emphasis on excluding osseous lesions. Discoligamentary injuries may be masked by unique clinical situations presenting to the emergency physician. We report on the case of a 28-year-old patient being admitted to our emergency department after a snowboarding accident, with an assumed hyperflexion injury of the cervical spine. During the initial clinical encounter the only clinical finding the patient demonstrated, was a burning sensation in the palms bilaterally. No neck pain could be elicited and the patient was not intoxicated and did not have distracting injuries. Since the patient described a fall prevention attempt with both arms, a peripheral nerve contusion was considered as a differential diagnosis. However, a high level of suspicion and the use of sophisticated imaging (MRI and CT) of the cervical spine, ultimately led to the diagnosis of a traumatic disc rupture at the C5/6 level. The patient was subsequently treated with a ventral microdiscectomy with cage interposition and ventral plate stabilization at the C5/C6 level and could be discharged home with clearly improving symptoms and without further complications.This case underlines how clinical presentation and extent of injury can differ and it furthermore points out, that injuries contracted during alpine snow sports need to be considered high velocity injuries, thus putting the patient at risk for cervical spine trauma. In these patients, especially when presenting with an unclear neurologic pattern, the emergency doctor needs to be alert and may have to interpret rigid guidelines according to the situation. The importance of correctly using CT and MRI according to both - standardized protocols and the patient's clinical presentation - is crucial for exclusion of C-spine trauma.

Pica and refractory iron deficiency anaemia: a case report

ABSTRACT: INTRODUCTION: Iron deficiency is the most common cause of anaemia worldwide. Pica, the ingestion of substances that are inappropriate for consumption, is associated with iron deficiency and may be under-diagnosed. CASE PRESENTATION: A 34-year-old woman presented with iron deficiency anaemia refractory to treatment for more than a decade. The clinical presentation, endoscopic findings and laboratory investigations were consistent with pica. Subsequent geophysical analysis confirmed that the ingested material was kaolin, a negatively charged silicate. CONCLUSION: Prolonged unexplained iron deficiency anaemia should prompt clinicians to remember and inquire about pica. In our patient, this would have averted numerous unnecessary investigations and prevented a decade-long suffering.

Simultaneous, bilateral anterior ischemic optic neuropathy (AION) in polycythemia vera: a case report

BACKGROUND: Polycythemia vera (PV) is a hemopoetic disorder. Apparently, although thrombosis accounts for the majority of morbidity, AION has not been associated with PV so far. PATIENT AND FINDINGS: A 63 y-old woman with PV was hospitalized because of acute liver failure. She also experienced bilateral painless loss of vision. Bilateral, pale optic disc swelling with flame-like hemorrhages, more pronounced in the right eye, constricted visual fields, and relative afferent papillary defect (RAPD) on the right side were present. Computer tomography scan revealed no signs of intraorbital pathology, elevated intracranial pressure or hemorrhages. CLINICAL COURSE: We interpreted the findings as AION associated with the hyperviscosity syndrome. Liver transplantation had to be carried out in the next days. Three weeks later, vision improved slightly, but RAPD persisted, and disc pallor developed in both eyes. The patient died two months later. DISCUSSION: Central retinal artery and vein occlusions have been described as complications of Essential thrombocythemia, but not of PV. We observed a rare case of bilateral neuropathy suggestive of AION. This condition has so far not been associated with PV.

[Case report of osteo-odonto keratoprosthesis (Strampelli) and of Dacron keratoprosthesis (Pintucci)]

BACKGROUND: In severe forms of ocular surface disorders keratoprostheses provide the ultimate possibility to restore vision. They are made of an optical cylinder integrated with a supporting biocompatible or biological haptic. CASE REPORT: We report on two patients with different types of keratoprostheses. An 88-year-old woman with ocular pemphigoid received in 1970 a bilateral osteo-odonto-keratoprosthesis (Strampelli). A 59-year-old man with refractory corneal ulcer after corneal grafting received in 2003 a keratoprosthesis with supporting Dacron tissue (Pintucci). RESULTS: The course 35 years after implantation of the osteo-odonto-keratoprosthesis was uneventful. Histologically there were no signs of loosening, rejection or infection. The autologous dentin, which was used for the fixation, was still present. The eye with the Dacron fixated prosthesis (Pintucci) had to be enucleated due to a loosening with endophthalmitis one and a half year after implantation. CONCLUSIONS: Keratoprostheses with autologous fixation often show good long-term results. On the other hand, prostheses with synthetic material are more often complicated by dislocation and inflammation.

[Primary malignant melanoma of the parotid gland: a case report and review of the literature]

Malignant melanomas (MMs) of the parotid gland are relatively uncommon. They occur almost invariably as metastases from a primary tumour located in the region of the scalp or the mucous membranes of the nose, paranasal sinuses, or throat. Primary MMs arising in the parotid gland are extremely rare. It is assumed that they originate in the glandular tissue or in intraglandular lymph nodes. We present a case report and review of the literature on the diagnosis, treatment, and prognosis of intraparotid malignant melanoma. Diagnosis is based primarily on B-scan ultrasonography and fine-needle aspiration cytology. Patients with a cytological diagnosis of MM are further evaluated by magnetic resonance imaging and positron emission tomography and receive a thorough ear-nose-throat and dermatological examination. The treatment of choice is total parotidectomy and selective neck dissection. The effectiveness of adjuvant treatments such as radiotherapy, chemotherapy, or immunotherapy remains controversial. Patients with primary MMs of the parotid gland appear to have a better prognosis than those with parotid metastases from melanomas of the skin or mucous membranes.

Lhermitte-Duclos disease with atypical vascularization--case report and review of the literature

OBJECTIVE: A case of Lhermitte-Duclos disease (LDD, dysplastic gangliocytoma) with atypical vascularization is reported. LDD is a rare cerebellar mass lesion which may be associated with Cowden's syndrome and the PTEN germline mutation. CASE MATERIAL: A 61-year-old male presented 15 years before with a transient episode of unspecific gait disturbance. Initial magnetic resonance (MR) imaging revealed a right-sided, diffuse, nonenhancing cerebellar mass lesion. No definitive diagnosis was made at that time, and the symptoms resolved spontaneously. 15 years later, the patient presented with acute onset of vomiting associated with headache and ataxic gait. MR imaging showed a progression of the lesion with occlusive hydrocephalus. The lesion depicted a striated pattern characteristic for LDD with T1-hypointense and T2-hyperintense bands, nonenhancing with contrast. After resection of the mass lesion, the cerebellar and hydrocephalic symptoms improved rapidly. The pathological examination confirmed the diagnosis of dysplastic gangliocytoma (WHO Grade I) with enlarged granular and molecular cell layers, reactive gliosis and dysplastic blood vessels. No other clinical features associated with Cowden's syndrome were present. CONCLUSIONS: This case illustrates that LDD with atypical vascularization is a slow-growing posterior fossa mass lesion which may remain asymptomatic for many years. Timing of surgical treatment and extent of resection in patients with LDD is controversial. The typical features on standard T1-/T2-weighted MR imaging allow a diagnosis without surgery in most cases. The authors believe that the decision to treat in these cases should be based on clinical deterioration.

Surgical approach for synovial cyst of the atlantoaxial joint: a case report and review of the literature

STUDY DESIGN: Case report and review of the literature. OBJECTIVE: We describe the first case of a synovial cyst arising from pseudarthrosis of a previous dens fracture. The literature is reviewed and etiological, diagnostic, and therapeutic options of atlantoaxial cysts are discussed. SUMMARY OF BACKGROUND DATA: Symptomatic synovial cysts of the atlantoaxial joint are rare. To the authors' knowledge only 24 cases have been reported.A 60-year-old patient presented with bilateral hand numbness, quadrihyperreflexia, and gait deterioration. Magnetic resonance imaging of the cervical spine disclosed a cystic mass located at the transverse ligament of dens axis causing bulbomedullary compression. METHODS: Surgery was performed via transoral image guided approach. The ventral atlas arch, dens, transverse ligament, tectorial membrane, and the compressing cyst were removed, followed by a C0-C3 fusion. RESULTS: Two months postsurgery the patient recovered completely from the cervical myelopathy with transient remnant dysparesthesia of the finger tips. CONCLUSION: Magnetic resonance imaging findings are not specific enough to establish a preoperative diagnosis. Radical resection via image-guided transoral route followed by posterior fusion allows complete resection of the cystic lesion and results in excellent long-term decompression.
