The author obtained index of red cell volume distribution width(RDW) and other red cell indices in 210 patients of various hematoncologic conditions and 200 healthy control group using, an automated blood analyzer, Coulter Counter Model S-plus II. This study performed to classify various etiologic anemia based on the MCV and RDW, to evaluate availability to the differential diagnosis in korean anemic distoders somewhat different from etiologies of anemias in foreginers. In the most of cases, the increase or decrease of MCV were always combined the pararell changes of MCH and MCHC: But the values of MCV and RDW were not correlated in control group and patient group. So the terms of heterogenous of homogenous anemia were meaningful morphologic classification than hypochromic or normochromic anemia. The heterogenous microcytic anemia contained iron deficiency anemia. In heterogenous normocytic anemia, myelophthisic anemia, acute leukemia were contained. In heterogenous macrocytic anemia, megaloblastic anemia, hemolytic anemia were contained. The homogenous microcytic anemia was observed in anemia of chronic disorders. In homogenous normocytic anemia, acute blood loss, chronic leukemia, multiple myeloma were contained. The aplastic anemia was belonged to homogenous macrocytic anemia. The diagnostic significance of RDW in hemoglobinopathies is most importhant. But this study was not contained hemoglobinopathies. Instead RDW was very helpful to differential diagnosis of most common anemias, iron deficiency anemia and anemia due to chronic disorders in Korea.

A clinical review of 31 cases of multiple myeloma which were diagnosed by criteria of the SWOG between May 1983 and February 1990 at Yeungnam University Hospital was done. The results were as followings: 1. The peak incidence was in 7th decade and male to female ratio was 1.8:1. 2. The most common presenting symptom at first diagnosis was bone pain (58%), but fever, dyspnea, dizziness and palpable mass were also noted. 3. The distribution of laboratory findings as following diagnostic criteria of Southwest oncology group (SWOG): Plasmacytoma on tissue biopsy was noted 6 cases, bone marrow plasmacytosis with more than 10% plasma cells was 22 cases, monoclonal globulin spike on serum electrophoresis was 24 cases, lytic bone lesions was observed 22 cases. 4. Initial clinical stages were classified as 2 cases in stage I, 3 cases in stage II, 26 cases in stage III (84%). 5. Immunoelectrophoresis revealed the distribution of IgG 64%, light chain 22%, IgA 10%, Kappa to Lambda ratio of 1.1:1. 6. Hematologic & biochemical findings revealed anemia with <8.5% of hemoglobin in 42%, hypercalcemia with <10.6 mg% of serum calcium in 22%, azotemia >2.0 mg% of serum creatinine in 19%. 7. The multiple punched out lesion of bone x-ray examination were noticed skull (65%), rib (42%), L-spine (35%), pelvis (23%), T-spine (19%). The initial skeletal roentgenographic findings showed osteoporosis, osteolytic lesion and fracture in 55%, only osteolytic lesion in 23%, only osteoporosis in 10%. 8. Complications of multiple myeloma, such as 10 cases of renal impairment, 8 cases of infection, 16 cases of compression fracture of spine were observed.

Spontaneous intracranial hypotension (SIH) is usually a benign disease which mostly present as orthostatic headache and resolves by conservative treatment or epidural blood patch. However, in severe cases large subdural hematoma or brain caudal herniation can progress to brain herniation and neurologic complications. We introduce a rare case of SIH which presented as acute mental deterioration with unilateral acute subdural hematoma. A 60 years old female visited to emergency room for stuporous mental change and unilateral acute subdural hematoma. Decompressive craniectomy and hematoma removal was performed to release brain herniation and increased intracranial pressure. There was temporary improvement of consciousness, but sustained leakage of cerebrospinal fluid (CSF) and caudal brain herniation worsened patient's condition. After recognizing that CSF leakage and hypovolemia was the underlying disease, emergent epidural blood patch and early cranioplasty was performed. After treatment CSF volume was normalized and patient recovered completely without neurologic deficits. Acute mental deterioration with unilateral subdural hematoma is a rare presentation for SIH. Treatment strategy for subdural hematoma with concomitant SIH patients, should be planned carefully with concerns to CSF hypovolemia and intracranial pressure.

BACKGROUND: The Mega Acer Kit(R) (MAK) is a newly designed heated and humidified breathing circuit that warms fluid passing through the circuit lumen. In this study, we investigated the system's efficacy for the perioperative prevention of hypothermia and fluid warming. METHODS: Ninety patients undergoing spinal surgery were enrolled in this study and randomly assigned to 3 groups based on the fluid warming device used: no fluid warming system (Group C, n = 30), via a Standard Ranger (Group R, n = 30), or via the MAK (Group M, n = 30). Distal esophageal temperatures (Teso) and infusion fluid temperature (TF) were recorded at 15 min intervals for duration of 180 min during surgery. If Teso was < 35.0degrees C, a forced-air convective warming device was used. RESULTS: Final Teso values were 34.8 +/- 0.3degrees C, 35.1 +/- 0.1degrees C, and 35.8 +/- 0.3degrees C in groups C, R, and M, respectively (P < 0.01). Teso was significantly higher in group M when compared with that in groups C and R throughout the study period (P < 0.05). The number of patients requiring a forced-air convective warming device was significantly lower in group M (n = 0) when compared with that in groups R (n = 17) and C (n = 30) (P < 0.05). The final infusion fluid temperature was higher in group M when compared with that in groups C and R throughout the study period (35.4 +/- 1.0 vs. 23.0 +/- 0.3 and 32.8 +/- 0.6degrees C; P < 0.01). CONCLUSIONS: The MAK is more effective for preventing hypothermia and for warming fluid than the Standard Ranger.

OBJECTIVE: Sacral insufficiency fracture (SIF) contributes to severe low back pain. Prolonged immobilization resulting from SIF can cause significant complications in the elderly. Sacroplasty, a treatment similar to vertebroplasty, has recently been introduced for providing pain relief in SIF. The purpose of this study is to investigate the clinical short-term effects of percutaneous sacroplasty on pain and mobility in SIF. METHODS: This study is conducted prospectively with data collection. Sixteen patients (3 men and 13 women) with a mean age of 77.5 years (58 to 91) underwent sacroplasty. Patients reported visual analogue scale (VAS; 0–10) and Oswestry disability index (ODI; 0–100%) scores. VAS and ODI scores were collected preoperatively and again at one day, one month, and three months postoperatively. Questionnaires measuring six activities of daily living (ADLs) including ambulating, performing housework, dressing, bathing, transferring from chair, and transferring from bed were collected. Ability to perform ADLs were reported preoperatively and again at three months postoperatively. RESULTS: The mean preoperative VAS score (mean±SD) of 7.5±0.8 was significantly reduced to 4.1±1.6, 3.3±1.0, and 3.2±1.2 postoperatively at one day, one month, and three months, respectively (p<0.01). The mean ODI score (%) also significantly improved from 59±14 preoperatively to 15.5±8.2 postoperatively at one month and 14.8±8.8 at three months (p<0.01). All ADL scores significantly improved at three months postoperatively (p<0.01). CONCLUSION: Percutaneous sacroplasty alleviates pain quickly and improves mobility and quality of life in patients treated for SIF.

PURPOSE: Adjuvant radiotherapy of breast cancer using a photon tangential field incurs a risk of late heart and lung toxicity. The use of free breathing (FB), expiration breath hold (EBH), and deep inspiration breath hold (DIBH) during tangential breast radiotherapy as a means of reducing irradiated lung and heart volume was evaluated. METHODS: In 10 women with left-sided breast cancer (mean age, 44 years) post-operative computed tomography (CT) scanning was done under different respiratory conditions using FB, EBH, and DIBH in 3 CT scans. For each scan, an optimized radiotherapy plan was designed with 6 MV photon tangential fields encompassing the clinical target volume after breast-conserving surgery. RESULTS: The results of dose-volume histograms were compared using three breathing pattern techniques for the irradiated volume and dose to the heart. A significant reduction dose to the irradiated heart volume for the DIBH breathing technique was compared to FB and EBH breathing techniques (p<0.05). CONCLUSION: This study demonstrated that the irradiated heart volume can be significantly reduced in patients with left-sided breast cancer using the DIBH breathing technique for tangential radiotherapy.

Diffuse pulmonary nodular lesions have many causes. When they are caused by infection, the likely organisms are M. tuberculosis and various fungi. Silicosis, eosinophilic granuloma and pulmonary metastasis should be considered for differential diagnosis. Differential diagnosis needs detailed clinical history, physical examination and various laboratory tests. A case of persistent diffuse pulmonary nodular lesions which had persisted 5 years is reported. The patient was a 25 years old man with minimal pulmonary symptoms. Detailed past history and physical examination suggested thyroid tumor. Chest radiography showed numerous evenly sized well-defined nodules scattered in entire lung fields. Previous chest X-rays showed similar nodular lesions, which had lasted for 5 years. The number of nodules was slightly increased. Neck CT showed heterogenous mass in left lobe of thyroid gland and multiple lymphadenopathies along both internal jugular chains. Total thyroidectomy was performed. A case of lung metastasis which progressed slowly in papillary thyroid cancer is reported.

Cryoglobulinemia is the presence of globulins in the serum that precipitate on exposure to cold temperatures (cryoglobulins). Pulmonary complications of cryoglobulinemia include interstial infiltration, impaired gas exchange, small airway disease and pleurisy. Only one other acute respiratory distress syndrome(ARDS) case has been described in patients with cryoglobulinemia. A 55-years old man was admitted with dyspnea. He had been diagnosed as being a hepatitis B virus antigen carrier 15 years age. On the first admission, chest radiography showed a bilateral pleural effusion and a patchy infiltration on both lungs. On protein-and immuno-electrophoresis, cryoglobulinemia was confirmed. The patient was treated with corticosteroid and plasmapheresis. Forty-five days after the diagnosis, the patient complained of progressive dyspnea and showed a diffuse bilateral pulmonary infiltration on chest radiography. Despite intensive care with mechanical ventilation, the patient died as consequence of hypoxemia and multiple systemic organ failure. On a pathologic examination of the postmortem lung biopsy, multiple necrotizing vasculitis and increased infiltration of the lymphocytes and monocytes were observed. In conclusion, ARDS developed as a result of pulmonary hemorrhage due to cryoglobulinemia-associated vasculitis.
