A Case of Pulmonary Paragonimiasis with Recurrent Pleural Effusion and Cured by Four Cycles of Chemotherapy / 결핵및호흡기질환

Paragonimiasis is a parasitic infection that occurs following the ingestion of infectious Paragonimus metacercariae, which occurs as a result of eating raw or undercooked freshwater crabs or crayfish. Pulmonary paragonimiasis is the most common clinical manifestation of this infection. Human paragonimiasis occurs sporadically. We experienced a case of pulmonary paragonimiasis in a 35-year-old woman with left lower chest pain. The patient had hypereosinophilia and a pleural effusion. The diagnosis was confirmed by positive ELISA (Enzyme-linked immunosorbent assay) that detected Paragonimiasis westermani antibody in the serum. We treated the patient with praziquantel for two days at a daily dosage of 75 mg/kg. Left pleuritic pain and pleural effusion improved after treatment. However, similar symptoms and pleural effusion developed recurrently for the first 3 courses of treatment with praziquantel. Upon the fourth round of treatment, the patient made a full recovery.

Sinus Histiocytosis with Massive Lymphadenopathy: A Case Report with Pleural Effusion and Cervical Lymphadenopathy

Sinus histiocytosis with massive lymphadenopathy (SHML) is a rare disorder characterized by a nonneoplastic proliferation of distinctive histiocyte cells within lymph node sinuses and lymphatics in extranodal sites. SHML occurs worldwide and is primarily a disease of childhood and early adulthood. A 26-yr-old man presented with painless palpable lymph node in cervical area. Radiographic studies revealed pleural effusion with lymphadenopathy and calcification in mediastinum. The cervical lymph node biopsy showed dilated sinuses filled with histiocytes with clear cytoplasm. The cells stained positive with CD68 and S-100. These cytologic and immunohistochemical findings were considered consistent with the diagnosis of SHML.

Sarcoidosis Initially Presenting as a Nasal Cavity Mass Misdiagnosed as Tuberculosis / 결핵및호흡기질환

We experienced a rare case of sinonasal sarcoidosis initially presenting as nasal cavitary mass. When the clinical course was different from that of typical tuberculosis, physician should think the possibility of sarcoidosis, and re-biopsy or retrospective review of pathological findings might be helpful.

A Case of Pseudoalveolar Sarcoidosis with Unilateral Pulmonary Infiltration / 결핵및호흡기질환

A sarcoidosis is a multisystemic granulomatous disorder that has a predilection for pulmonary involvement, and the common radiological findings for the disease are bilateral nodular or reticulonodular patterns. Pseudoalveolar sarcoidosis is a rare presentation of sarcoidosis. The radiological finding is an alveolar pattern that involves or compresses the alveoli by clustered interstitial granuloma. A 58-year-old man was admitted due to incidental findings of a unilateral consolidative lesion as seen on chest radiography. A chest computed tomography (CT) examination showed multiple bronchoalveolar consolidations that were suspicious of a malignancy. However, a percutaneous needle biopsy revealed non-caseating granuloma with an asteroid body that was compatible with sarcoidosis. After one month, the consolidative lesions improved without any treatment.

Two Cases of Iatrogenic Pneumothorax after Intra-Muscular Stimulation (IMS) Therapy / 결핵및호흡기질환

Recently, intra-Muscular Stimulation (IMS) therapy is being increasingly used for musculoskeletal pain. This procedure is generally regarded as a safe procedure for the general public. Some cases of iatrogenic pneumothorax caused by acupuncture have been reported in the medical literature. However, a case of an IMS therapy associated pneumothorax has not reported. We experienced two cases of iatrogenic pneumothorax after IMS therapy. A 62 year-old man received IMS therapy on the right shoulder due to posterior neck pain. After IMS therapy, acute dyspnea and chest discomfort developed. The other patient was a 74 year-old woman who also received IMS therapy. This patient experienced a nonproductive cough and acute dyspnea after the treatment. As the popularity of this form of alternative medicine increases, we might expect to see more cases of iatrogenic pneumothorax. Physicians should be aware of the adverse events associated with IMS therapy.

Two Cases of Fractured and Embolized Implanted Central Venous Chemoports in Lung Cancer / 결핵및호흡기질환

Totally implanted central venous access devices for chemotherapy (chemoport) are being used increasingly in lung cancer patients. Vascular catheters are associated with various complications including infection, thrombosis as well as spontaneous fractures and embolization of the catheter, which is known as 'pinch-off syndrome'. 'Pinch-off syndrome' refers to the compression of a subclavian central venous catheter between the clavicle and first rib resulting in an intermittent or permanent obstruction, which can lead to tears, transection, or embolization. We report two cases of fractured and embolized implanted subclavian venous catheters in which the fragments were removed percutaneously. A 62-year-old man presented with back pain with a duration of a few weeks. The chest radiograph revealed complete transsection and embolization of the catheter into the right atrium. In addition, a 47-year-old woman with a chemoport had a grade 3 pinch-off sign in a chest radiograph demonstrating complete transsection and embolization of the catheter into the pulmonary artery. Both cases were managed by retrieving the embolized distal fragment percutaneously and removing the proximal section of the catheter.

A study of clinically relevant initial loading dose of propofol during upper gastrointestinal endoscopy using sedation with propofol / 대한내과학회지

BACKGROUND: Sedation with propofol during esophagogastroduodenoscopy (EGD) has been increased. However, the use of propofol during EGD may have significant side effects such as hypoxemia and hypotension. We studied the dose of propofol for adequate sedation without side effects during EGD. METHODS: From June to August 2003, 46 healthy persons who visited St. Carollo hospital health management center for diagnostic EGD were enrolled for this study. Twenty four persons (Group A) were given a initial loading dose of propofol 60 mg (in person below 60 kg by body weight) and 80 mg (in person above 60 kg by body weight). Twenty two persons (Group B) were given a initial loading dose of propofol 80 mg and 100 mg at the same way. Additional dose of propofol which was injected once a minute until adequate sedation by 20 mg and maintenance dose during EGD were compared between two groups. Respiration rate, pulse rate, blood pressure, arterial oxygen saturation and ejection fraction of left ventricle were monitored. RESULTS: There were no significant differences between two groups in monitored parameters. Persons in group B were given significantly lower additional dose (p<0.001) and maintenance dose (p<0.05) of propofol. However total amount of propofol during EGD was not significantly different between two groups. CONCLUSION: In relatively young (under 60 years of age) and healthy persons without significant medical problem, 80 mg and 100 mg of propofol (in person below 60 kg and above 60 kg by body weight) as initial loading dose of propofol during EGD are more clinically relevant than 60 mg and 80 mg of propofol (in person below 60 kg and above 60 kg by body weight).

The Effect of Primary Percutaneous Coronary Intervention after the Administration of Tirofiban Alone or Tirofiban Combined with Low dose Alteplase in Patients with Acute Myocardial Infarction on ST Elevation Resolution, TIMI Flow and Short-Term Clinical O

BACKGROUND AND OBJECTIVES: The combination of platelet glycoprotein IIb/IIIa inhibitors and a low dose thrombolytic agent may produce early Thrombolysis In Myocardial Infarction (TIMI) 3 flow and a high rate of ST elevation resolution in an ST elevation acute myocardial infarction (STEMI). The clinical effect of tirofiban combined with low dose alteplase, prior to primary percutaneous coronary intervention (PCI) in STEMI, were evaluated on the ST elevation resolution, TIMI flow and 30-day clinical outcomes. SUBJECTS AND METHODS: Following aspirin, clopidogrel and standard heparin, 45 patients with STEMI were randomized into 2 groups; tirofiban administration (Group I; n=23, 64+/-10 years; 15 male) or combined administration of tirofiban with 40 mg alteplase prior to primary PCI (Group II; n=22, 59+/-11 years; 19 male). The pre- and post-interventional TIMI flow grades, ST elevation resolution and bleeding complications were compared between the two groups. The major adverse cardiac events (MACE) were compared between the two groups during 30-days of clinical follow-up. RESULTS: Group II had a higher pre-interventional TIMI flow (TIMI flow> or =2: 34.8% vs. 90.9%, p<0.0001) and rate of ST elevation resolution (49.0+/-27.8% vs. 66.6+/-27.2%, p=0.045) than Group I. A major bleeding complication developed in 1 (5.0%) Group II patient, and minor bleeding complications developed 1 patient from each group (Group I; 9.5% vs. Group II; 10%, p=0.959). CONCLUSION: Combined administration of tirofiban with alteplase prior to primary PCI leads to a higher TIMI flow and more frequent ST elevation resolution, without bleeding complications, compared to a single administration of tirofiban.
