  • Histomonas meleagridis is a facultative anaerobic parasite, which can cause a common poultry disease known as histomoniasis. The species and age of the birds impacts on the susceptibility, with turkey being the most susceptible species. Chickens are less susceptible to H. meleagridis than turkeys and usually serve as reservoir hosts. Here, the diagnosis of an outbreak of histomoniasis in backyard Sanhuang chickens is described. The primary diagnosis was made based on clinical symptoms, general changes at necropsy, histopathology, and the isolation and cultivation of parasites. The pathogen was further confirmed by cloning, PCR identification, and animal inoculation tests. A strain of H. meleagridis, named HM-JSYZ-C, with a higher pathogenicity level in chickens was obtained. The study lays a foundation for further investigations into H. meleagridis and histomoniasis in chickens.

  • The causes of sciatica are variable and include musculoskeletal, dermatologic, infectious, neoplastic, and vascular disorders. In many cases, the symptom is usually caused by degenerative disease in the spine with the compression or irritation of spinal nerve. On the other hands, there are also several announced extra-spinal causes including aneurysm, diabetes, and radiation for sciatica in a low rate. Among the extra-spinal cases, aneurysms arising from iliac vessels are sometimes developing a diagnostic confusion with the spinal causes, and delayed diagnosis can lead to poor prognosis. It is very important to pay attention weather the aneurysmal cause is involved in the symptom of sciatica.

  • Diffuse alveolar hemorrhage (DAH) is a life-threatening and medical emergency that can be caused by numerous disorders and presents with hemoptysis, anemia, and diffuse alveolar infiltrates. Early bronchoscopy with bronchoalveolar lavage is usually required to confirm the diagnosis and rule out infection. Most cases of DAH are caused by capillaritis associated with systemic autoimmune diseases such as anti-neutrophil cytoplasmic antibody-associated vasculitis, anti-glomerular basement membrane disease, and systemic lupus erythematosus, but DAH may also result from coagulation disorders, drugs, inhaled toxins, or transplantation. The diagnosis of DAH relies on clinical suspicion combined with laboratory, radiologic, and pathologic findings. Early recognition is crucial, because prompt diagnosis and treatment is necessary for survival. Corticosteroids and immunosuppressive agents remain the gold standard. In patients with DAH, biopsy of involved sites can help to identify the cause and to direct therapy. This article aims to provide a general review of the causes and clinical presentation of DAH and to recommend a diagnostic approach and a management plan for the most common causes.

  • Cockroach antigen have been known as a cause of allergic disease. German ockroach(Blattella germanica L.) was chosen because it has the highest distribution range and poulation density. To identify the common and specific antigens of adult and larval stage of german cockroach, we made monoclonal antibodies which were confirmen by SDS-PAGE and EITB. Anti-B. germanica antibody producing hybridomas were 24 among the total 960wells. Only 4 hybridomas did not have cross reaction to other species of cockroach and hluse dust mites(Dermatophagodies farinae and D. pteronyssius). SDS-PAGE revealed about 20 bands from 90Kd to 15Kd to 15Kd. ETB showed specific antigens a6 60, 72 and 82Kd which were experimented by the culture supernatant of 4 selected hybridomas. Especially 60Kd coincided with a band of immunized mouse sera.

  • Fifty-two cases of spontaneous pneumothorax encountered in Seoul National University Hospital during the period from 1961 to 1968 were reviewed. The incidence was highest in the adult between 21 and 40 years of age, showing 50%. Four cases of bilateral spontaneous pneumothorax [7.7%] were noted. Pulmonary tuberculosis was the most common cause, 50% of the cases. Non-tuberculous group was 26 cases [50%], of which 15 cases were idiopathic, 5 emphysematous bullae or blebs, 5 inflammatory lung disease, mostly pneumonia, and one pulmonary paragonimiasis. Among 52 cases, the lung expanded completely with absolute bed rest in 7 cases, 3 out of 9 with needle aspiration and bed rest, 34 out of 41 with closed thoracotomy and underwater seal Stedman suction, and 7 cases were treated with open thoracotomy with resection of the lesions without complication. Among these cases treated with closed thoracotomy it took about 3 days in non-tuberculous group to expand the collapsed lung and more than 2 weeks in tuberculous group.

  • As diagnostic techniques have advanced, primary aldosteronism (PA) has emerged as the most common cause of secondary hypertension. The excess of aldosterone caused by PA resulted in not only cardiovascular complications, including coronary artery disease, myocardial infarction, arrhythmia, and heart failure, but also cerebrovascular complications, such as stroke and transient ischemic attack. Moreover, PA is associated more closely with these conditions than is essential hypertension. In this review, we present up-to-date findings on the association between PA and cerebrovascular diseases.

  • We experienced 48 operations in 46 surgical patients of bronchiectasis admitted to the Department of Thoracic and Cardiovascular Surgery of Jeonbug National University Hospital from January, 1975 to August, 1982. Among 46 patients, 27 patients [59%] was age group between 21 to 30 years. Common symptoms were cough with sputum, hemoptysis, dyspnea, fever and chilliness, and chest pain. The duration of the symptoms was variable between below one year and above 10 years. The most frequent associated disease, probably the cause of the bronchiectasis, was secondary bacterial infection after viral infection. The left lower lobe and lingular segment was involved most frequently, and the most frequent pathologic type was mixed type [40%]. Single lobectomy, and combined lobectomy and segmentectomy were performed in 77% of the patients. Bilateral resection was performed in three patients with good result. In those patients, the isolated pulmonary function test on each side of the lung performed 2 month later primary lung resection could make them be prevented from pulmonary insufficiency after secondary lung resection. The results were good except two patients who developed pulmonary insufficiency and chronic empyema with bronchopleural fistula.

  • Restless legs syndrome (RLS) is a sleep disorder characterized by an urge to move the legs or arms and uncomfortable paresthesia in the legs. Treatment of RLS can be various depending on the causes, severity, and frequency of the symptoms. In the case of secondary RLS, it is important to identify and manage the cause of RLS. Dopamine agonists have been used as firstline treatments for primary RLS treatment. However, due to augmentation, which is a common side effect of dopamine agonists, recent treatment guidelines are changing to prefer to anticonvulsants such as pregabalin and gabapentin. Iron, opioid, or benzodiazepine may be used when anticonvulsants or dopamine agonists are not adequately treated. Because RLS is a chronic disease, it is essential to establish a long-term treatment plan considering both efficacy and side effects.

  • Urinary tract infection (UTI) is a common bacterial illness in children. Acute pyelonephritis in children may lead to renal scarring with the risk of later hypertension, preeclampsia during pregnancy, proteinuria, and renal insufficiency. Until now, vesicoureteral reflux (VUR) has been considered the most important risk factor for post-UTI renal scar formation in children. VUR predisposes children with UTI to pyelonephritis, and both are associated with renal scarring. However, reflux nephropathy is not always acquired; rather, it reflects reflux-associated congenital dysplastic kidneys. The viewpoint that chronic kidney disease results from renal maldevelopment-associated VUR has led to questioning the utility of any regimen directed at identifying or treating VUR. Despite the recognition that underlying renal anomalies may be the cause of renal scarring that was previously attributed to infection, the prevention of renal scarring remains the goal of all therapies for childhood UTI. Therefore, children at high risk of renal scar formation after UTI should be treated and investigated until a large clinical study and basic research give us more information.
