Sphenoid sinus aspergillosis is notorious for its serious complications, such as permanent cranial nerve deficits and possible death. The most common associated symptoms are headache, followed by visual changes, and cranial nerve palsies. Because of an insidious onset, frequently resulting in missed and delayed diagnosis, sphenoid sinus aspergillosis is a potentially lethal medical condition. We report a case of visual loss secondary to isolated sphenoid sinus aspergillosis. A 69-year-old man presented to our hospital with the complaint of headache. The headache started one year previously and was described as severe dull pain localized bilaterally to the temporo-orbital region. The patient took daily NSAIDs for the pain. The neurological examination was normal. The MRI of the brain showed a left sphenoid sinusitis. A transnasal endoscopic superior meatal sphenoidotomy was performed. Aspergillosis was confirmed after a surgical biopsy was obtained. The patient was discharged from hospital without antifungal therapy. One month later, the patient complained of headache and loss of vision bilaterally. The orbital MRI showed a left cavernous sinus and bilateral optic nerve invasion. The loss of visions was permanent. In our case, the diagnosis was delayed; antifungal agents were not administered after surgery and the patient lost his vision as a result. Therefore, early diagnosis and proper treatment are important. Although the treatment of an invasive type of aspergillus has not been established, surgical removal of a nidus and aggressive antifungal therapy are recommended.

Alzheimer's disease (AD) is a progressive neurodegenerative disorder of insidious onset that causes gradual loss of memory and cognitive function, and it is the most common form of dementia in the elderly. AD is characterized by neuritic plaques and neurofibrillary tangles in the brain, together with loss of neuronal cells. The major neuropathological hallmark of AD is the accumulation of extracellular neurotoxic ${\beta}-amyloid$ ($A{\beta}$) peptides, such as $A{\beta}1-42$, in the brain. In the present study, we investigated the effect of sargachromenol (SCM), sargaquinoic acid (SQA) and sargahydroquinoic acid (SHQA) isolated from Sargassum serratifoilum ethanol extract (SSE) on $A{\beta}$ production in vitro using APP751-transfected Chinese hamster ovary cells (CHO-751). CHO-751 cells were treated with various concentrations of SSE, SCM, SQA and SHQA, and the level of extracellular $A{\beta}1-42$ was evaluated by enzyme-linked immunosorbent assay. SSE and SHQA reduced the production of $A{\beta}1-42$ in CHO-751 cells. Therefore, SHQA isolated from S. serratifolium has potential as an inhibitor of neurotoxic $A{\beta}$ peptide production.

Amiodarone is widely used to control fatal arrhythmia. However, amiodarone therapy is associated with a relatively high incidence of pulmonary toxicity, up to 5 to 10%. Typical symptoms are nonspecific and often manifest as nonproductive cough, dyspnea and interstitial infiltrates in patients with acute pneumonitis or chronic fibrosis. However, hemoptysis is a very rare symptom of amiodarone pulmonary toxicity. We report a case of amiodarone pulmonary toxicity, who presented with hemoptysis and was successfully treated with the cessation of amiodarone, with review of the relevant literature.

Purpose : To propose the diagnosis, 'hypertrophy of the anterior cruciate ligament(ACL)', and its clinical, radiological and pathological characteristics. Materials & Method : Since Dec. 1995, we have experienced 10 patients(12 knees) with hypertrophy of the ACL. There were 2 males and 8 females, and the age of the patients ranged from 35 to 67 years. Characteristics of clinical, radiological and pathological findings were analysed. Results : The chief complaint was insidious onset of dull pain on the knee which became worse with activity. The constant physical finding was painful limitation of full extension of the knee. Sagittal MR images showed diffuse swelling of the ACL, similar finding that could be seen in acute ACL tear. Arthroscopically, noted was a marked enlargement of the ACL causing notch impingement. Biopsies of the hypertrophied ACL showed increased collagenous tissue with variable degree of myxoid degeneration. With partial excision of the hypertrophied ACL with or without notchplasty, the symptoms improved in all. Conclusion : Hypertrophy of the ACL, a newly proposed diagnosis, should be considered be determining the cause of the painful knee, and further study should be done about its pathogenesis.

Anterior knee pain syndrome would best be defined as a painful condition that arises in or around the patellofemoral joint and is insidious in onset and bilateral, with an enigmatic entity with multiple causes. Although its etiology is uncertain, the cause is often considered to be abnormal lower limb biomechanics, pathology of extensor mechanism, disorder of patellofemoral joint, malalignment or lateral tracking of the patella, soft tissue tightness, muscle weakness. The measurement of patellar alignment has come to be accepted as an integral part of the examination of anterior knee pain syndrome. Various measurement techniques exist, both clinical and radiological, and these have been frequently used in the diagnosis and treatment of the condition.?Treatment depends on the underlying cause of anterior knee pain and should be directed to the cause rather than to the results. Most often, this involves non-surgical measures, such as anti-inflammatory medications, quadriceps exercises, and hamstring stretching. Shin splint, or medial tibial stress syndrome refers a syndrome of pain running along the inner distal 2/3 of tibia shaft. Shin splint is a common problem for athletes whose sport involves a repeated, jarring impact to the leg. A major factor determining the efficacy of the treatment is that correct diagnosis be made of the problem. The varied etiology has led to the development of several theories as to the cause, treatment, rehabilitation and prevention of shin splint. The management is rest, ice massages, pain relief by medication, and muscle strengthening exercise. Proper rehabilitation and preventative measures can ensure that there is no further recurrence.

The lungs are frequently the site of adverse drug reactions because of their higher oxygen concentration, the distinctive properties of the pulmonary circulation, and the close proximity of the alveolar epithelium to the blood. Amiodarone, an iodinated benzofuran derivative, is an effective antiarrhythmic drug commonly used for refractory tachyarrhythmia. However, it has a wide range of adverse effects, the most serious of which is lung disease. Most patients present with the insidious onset of dyspnea and a nonproductive cough, and generally recover after withdrawing the drug. We recently experienced four fatal cases of amiodarone pulmonary toxicity. Therefore, we discuss these unusual drug-induced pulmonary toxicity cases with a review of the relevant literature.
