Cryptogenic organizing pneumonia (COP) is an inflammatory lung disease involving the distal bronchioles, respiratory bronchioles, bronchiolar ducts, and alveolae. The etiology is usually unknown; however, there are several known causes and associated systemic diseases. Corticosteroid therapy is the best treatment option and the prognosis of COP is good, with recovery in up to 80% of patients. We described a patient with in-operable hepatocellular carcinoma (HCC) undergoing chemoembolization with doxorubicin in a drug-eluting bead (DEB). COP developed in the patient after chemoembolization but resolved spontaneously in several months.

Triamcinolone acetonide (TA) is a corticosteroid that is used in the systemic and topical treatment of many inflammatory diseases. In this study, a phonophoretic drug delivery system was designed to enhance the TA permeability and the influence of ultrasound was examined. In order to establish the transdermal delivery system for TA, a hydrophilic carbopol gel containing TA was prepared after adopting phonophoresis. A permeation study through mouse skin was performed at $37^{\circ}C$ using a Franz diffusion cell, and the ultrasound treatment was carried out for 10 h. The level of TA permeation through the skin was evaluated under various ultrasound conditions including the frequency (1.0, 3.0 MHz), intensity (1.0, $2.5W/cm^2 $), and duty cycle (continuous, pulse mode) using a 0.5% TA gel. The highest permeation was observed under the ultrasound treatment conditions of low frequency, high intensity, and in continuous mode.

PCP remains the leading cause of deaths in patients with AIDS. As familiarity with PCP increases, atypical manifestations of the diseases are being recognized with greater frequency. There are following "atypical" manifestations of PCP ; 1) interstitial lung response that include diffuse alveolar damage, bronchiolitis obliterance, interstitial fibrosis, and lymphoplasmocytic infiltrate 2) striking localized process frequently exhibiting granulomatous features 3) extensive necrosis & cavitation 4) extrapulmonary dissemination of the disease. A wide variety of pathologic manifestations may occur in PCP in human immunodeficiency virus-infected patienst and that atypical features should be sought in lung biopsies from patients at risk for PCP. We had experienced a case of PCP, which presented with severe hypoxia, progressive dyspnea and fine crackles. It was diagnosed as PCP in AIDS with manifestation of BOOP by open lung biopsy and showed good response to Bactrim & corticosteroid therapy.

With the aid of extracorporeal circulation, nine dogs underwent orthotopic cardiopulmonary transplantation after preservation of the donor heart in a hypothermic amino acid[glutamate, aspartate] enriched high potassium extracellular solution, and preservation of the donor lung with hypothermic low potassium dextran solution from June 1990 to May 1991. The mean body weights of dogs were 20kg and the recipients` preoperative hematologic and hemodynamic pictures were within normal range except slightly decreased level of albumin and total protein, which was supposed to be due to malnutrition. The following modifications of the original Stanford technique were emphasized: [1] the posterior mediastinum is dissected as little as possible with meticulous hemostasis; [2] the surgical procedure is kept away from the phrenic and vagus nerves; [3] the tracheal anastomosis may be wrapped with recipient`s pulmonary artery flap or surrouding soft tissues. A combination of Cyclosporine, Azathioprine, corticosteroid was used as perioperative immunosuppressive therapy. Postoperatively all recipients could be weaned from extracorporeal circulation, showing favorable vital signs, but within 24 hours, irreversible congetive heart failure, ascites, arrhythmias developed with a mean survival time 13.6$\pm$6.6[n=9, range=6~26] hours. Hemoglobin and platelet counts were significantly[p<0.05] decreased postoperatively, which is thought to be attributed to blood damage by cardiopulmonary bypass and hemodilution. Postmortem finding included multiple subendocardial patch hemorrhage in both atrial and ventricular cavities, pulmonary and liver congestion, and all tracheal anastomoses were intact. Further consideration about quality control of the animal, infection, rejection, the effect of cardiopulmonary bypass on the experimental animal is required to improve the results.

Purpose: With the popularity of implant therapy, clinicians need to know about treating the dental implant in patients with gingival involvement of oral lichen planus (OLP). The aim of this study is to evaluate the survival and success rates of dental implant and propose of clinical guidelines for implant treatment in OLP patient with gingival involvement. Methods: A literature search was performed in PubMed/Medline, and Cochrane database. Papers in English language published between 1990 and 2019 were evaluated. The focused questions were following; 1) Dose gingival OLP affect the survival and success rates of dental implants? 2) The management of OLP patients with gingival involvement receiving dental implant. Results: There was no study about the evaluation of dental implant only in gingival OLP patient. Five studies evaluating dental implants in OLP patients were included in this review. Implant survival rate was 100.0% in well-controlled OLP patients in all included studies. The use of topical/systemic corticosteroid in OLP patients was performed before and/or after implant placement in all included studies. Conclusions: The implant survival and success rates in well-controlled OLP patients did not different from that of non-OLP healthy subjects. The gingival OLP is associated with higher rate of peri-implant mucositis. Adequate management of gingival OLP lesions before and after implant insertion is required to reduce inflammation and associated bone loss.

Piriformis muscle syndrome is a condition that causes direct muscle pain around piriformis muscle or sciatica from irritated sciatic nerve and the diagnosis remains debatable. The main treatment is symptomatic relief from conservative therapy such as medication and piriformis stretching exercise, and various therapeutic injections including local anesthetic, corticosteroid, botulinum toxin can be considered for diagnostic and therapeutic purposes. In this case, a 54-year-old male who had sciatica and gait disturbance showed piriformis muscle hypertrophy in the pelvis MRI. From imaging studies, electrodiagnostic study and physical examination, he was diagnosed with piriformis muscle syndrome. He underwent trigger point injection and botulinum toxin injection into the piriformis muscle, and pain and gait disturbance significantly improved. This case reports a case of piriformis muscle syndrome with clinical symptom of gait disturbance, which was improved by botulinum toxin injection.

A 60-year-old man was diagnosed with stage IV squamous cell carcinoma of lung and treated with weekly doses of docetaxel and cisplatin. Tumor mass and mediastinal lymphadenopathy disappeared after 4.5 cycles of chemotherapy. At one week post final chemotherapy, the patients developed sudden shortness of breath. New, multifocal infiltrations developed on both lungs without definitive evidence of infection. Despite administration of broad spectrum antibiotics, the lung lesion did not improve, so bronchoalveolar lavage and computed tomography-guided lung biopsy were performed. The proportion of lymphocytes was increased markedly and histopathology revealed squamous cell carcinoma combined with bronchiolitis obliterans organizing pneumonia. After high dose corticosteroid therapy, dyspnea and the newly developed consolidation had decreased slightly. However, dyspnea and hypoxemia increased again because of aggravated lung cancer since chemotherapy had stopped. Chemotherapy couldn't be restarted due to the poor performance status of the patient. Later, patient died of respiratory failure from poor general condition and progression of lung cancer.

Non-islet cell tumor-induced hypoglycemia (NICTH) is associated with mesenchymal tumor types, including hemangiopericytoma, fibrosarcoma, mesothelioma, and neurofibroma, as well as carcinoma of the liver, adrenal glands, and kidneys. Non- islet cell tumors induce hypoglycemia by overproducing an abnormal form of insulin-like growth factor II (IGF m. Complete removal of the tumor or reduction of the tumor mass is a successful therapeutic strategy in cases of NICTH. However, if the tumor re-grows, curative resection is nearly impossible, and hypoglycemia occurs repeatedly. Glucocorticoids are effective in terms of long-term relief from hypoglycemia through promotion of gluconeogenesis in the liver, tumor suppression, production of 'big'-IGF-II, and correction of the attendant biochemical abnormalities involving the growth hormone (GH)-IGF axis. We found that administration of corticosteroid therapy to a patient suffering from NICTH resulted in improvement of hypoglycemia associated symptoms.
