Common intracranial complications following head injury are meningitis, usually associated with a basilar skull fracture or open-depressed skull fracture; delayed hematoma; hydrocephalus; and vascular injuries. Prophylactic antibiotics are not recommended for the management of basilar skull fractures. The best means of preventing infection from open-depressed skull fractures is operative debridement and thorough irrigation, though recent evidence suggests that select cases can be safely managed without operation. Serial CT scans should be obtained in severely head-injured patients to identify delayed hematomas. CT and MRI scans obtained several weeks or months after severe head injury frequently reveal enlarged ventricles, though only a small percentage of these patients have clinical hydrocephalus. Those that do, often benefit from a shunt. Vascular injuries frequently are not detected until ischemic symptoms develop hours or days after the injury. Recommended treatment for intimal tears or dissection is full anticoagulation, but in those with cerebral contusions or other intracranial lesions, this may present an unacceptable risk for intracranial hemorrhage. Pulmonary infections frequently occur following head injury, and can be associated with admission to the ICU and intubation. A large percentage of these infections are caused by enteric gram-negative organisms, and aggressive treatment with appropriate antibiotics is necessary. Aspiration of gastric contents is common in head-injured patients and is frequently complicated by bacterial superinfection. The routine use of antacids and H2 blocking agents leads to bacterial colonization of the stomach with anaerobes and gram-negative aerobes. Thus, empiric therapy for aspiration pneumonia should include clindamycin. Sinusitis is a frequent cause of fever and leukocytosis in patients with nasotracheal or nasogastric tubes in place for several days and often subsides spontaneously with removal of the tubes. Pulmonary edema is often caused by excessive fluid administration during resuscitation of these patients, and can be avoided by monitoring central venous pressures. Pulmonary edema may also be caused by ARDS, excessive catecholamine release, or primary cardiac failure. Most of these patients will benefit from early intubation and PEEP. Pulmonary emboli most often originate from deep venous thrombi, and there is increasing evidence that prophylaxis with low-dose heparin and pulsating boots can significantly reduce the incidence of both complications. Erosive gastritis is found in the majority of severely head-injured patients and may be due to ischemia of the gastric mucosa as well as gastric hyperacidity.(ABSTRACT TRUNCATED AT 400 WORDS)

Osteoplastic flap of the frontal sinus, described by Macbeth over 40 years ago, still is the best surgical approach for the diagnosis and definitive treatment of chronic disease. Forty-seven patients were treated with this technique between 1978 and 1995. The conditions treated were, by order of frequency: 16 fronto-ethmoidal mucocele, 12 osteoma, 12 hypertrophic sinusitis, and less frequent disorders, such as osteomyelitis (2), fibrous histiocytoma (2), tuberculosis (1), frontal fracture (1) and dilated pneumosinus (1). The surgical approach was coronal in 28 patients, brow in 18 and hemicoronal in 3. In some cases, other approaches were associated: 13 lateral rhinotomy, 6 sublabial and 1 intranasal. Nasofrontal duct obstruction was found in 89% of cases and erosion of one or more sinus walls in 70%. Intraoperative complications included 4 small dural tears, 1 with leakage of cerebrospinal fluid. Postoperative complications included 4 frontal deformity, 2 persistent frontal anesthesia, 1 supraorbital nerve neuralgia, 1 post-anticoagulant epistaxis and 1 death from pulmonary embolism.

We report 3 patients with Proteus syndrome (PS) who died suddenly from pulmonary embolism (PE). The first patient was a male diagnosed with PS at 12 years who had varicose veins, portal vein thrombosis, right iliac vein occlusion and recurrent PE. At age 25 years, he was admitted to the hospital with a severe headache. Despite therapeutic doses of warfarin, investigations for an acute episode of breathlessness showed PE and he was unable to be resuscitated. The second case was a 9-year-old male with PS who collapsed at home and could not be revived. Autopsy revealed that the cause of death was a PE associated with thrombosis of the deep veins (DVT). The third patient was a 17-year-old female undergoing inpatient treatment for sinusitis when she unexpectedly arrested. She could not be revived and a full autopsy revealed a large PE with no identified DVT. We conclude that PE is a serious complication of PS and recommend vigilance concerning the signs and symptoms of thrombosis and PE in individuals with PS, including children. Aggressive evaluation and treatment should be considered urgently in patients with PS and signs or symptoms of DVT.

Clinical experience has shown that allergic and non-allergic respiratory, metabolic, mental, and cardiovascular disorders sometimes coexist with bronchial asthma. However, no study has been carried out that calculates the chance of manifestation of these disorders with bronchial asthma in Saarland and Rhineland-Palatinate, Germany. Using ICD10 diagnoses from health care institutions, the present study systematically analyzed the co-prevalence and odds ratios of comorbidities in the asthma population in Germany. The odds ratios were adjusted for age and sex for all comorbidities for patients with asthma vs. without asthma. Bronchial asthma was strongly associated with allergic and with a lesser extent to non-allergic comorbidities: OR 7.02 (95%CI:6.83-7.22) for allergic rhinitis; OR 4.98 (95%CI:4.67-5.32) allergic conjunctivitis; OR 2.41 (95%CI:2.33-2.52) atopic dermatitis; OR 2.47 (95%CI:2.16-2.82) food allergy, and OR 1.69 (95%CI:1.61-1.78) drug allergy. Interestingly, increased ORs were found for respiratory diseases: 2.06 (95%CI:1.64-2.58) vocal dysfunction; 1.83 (95%CI:1.74-1.92) pneumonia; 1.78 (95%CI:1.73-1.84) sinusitis; 1.71 (95%CI:1.65-1.78) rhinopharyngitis; 2.55 (95%CI:2.03-3.19) obstructive sleep apnea; 1.42 (95%CI:1.25-1.61) pulmonary embolism, and 3.75 (95%CI:1.64-8.53) bronchopulmonary aspergillosis. Asthmatics also suffer from psychiatric, metabolic, cardiac or other comorbidities. Myocardial infarction (OR 0.86, 95%CI:0.79-0.94) did not coexist with asthma. Based on the calculated chances of manifestation for these comorbidities, especially allergic and respiratory, to a lesser extent also metabolic, cardiovascular, and mental disorders should be taken into consideration in the diagnostic and treatment strategy of bronchial asthma.

A 51-year-old man was diagnosed with eosinophilic granulomatosis with polyangiitis 6 years ago due to asthma, sinusitis, hypereosinophilia, and peripheral neuropathy based on the diagnostic criteria of American College of Rheumatology, and corticosteroid therapy achieved a remission. One year ago, he was hospitalized due to deep venous thrombosis (DVT) and pulmonary embolism, and rivaroxaban was administrated. He was admitted to our hospital for acute onset of diplopia and right hemiparesis. Peripheral blood examinations disclosed leukocytosis with hypereosinophilia. Perinuclear anti-neutrophil cytoplasmic antibodies were positive. Diffusion-weighted imaging showed multiple fresh ischemic lesions. Chronic ischemic lesions were seen in subcortical cerebral region. No stenosis or occlusion was shown in extracranial and intracranial arteries on magnetic resonance angiography. Ultrasonography of leg vein showed DVT. Right-to-left shunt through patent foramen ovale after Valsalva maneuver was seen on transesophageal echocardiography. Treatment with corticosteroid and cyclophosphamide alleviated clinical deterioration. Rivaroxaban was changed to warfarin. Diplopia and muscle strength of right limbs were improved. This is a first case of multiple cerebral infarction caused by paradoxical embolism due to patent foramen ovale with DVT based on hypercoagulable state of hypereosinophilia. Overall this case illustrates that eosinophilic granulomatosis with polyangiitis can be a risk factor for multiple cerebral infarction in the systemic phase and that transesophageal echocardiography and ultrasonography of leg vein should be conducted in stroke patient with eosinophilic granulomatosis with polyangiitis.
