3.Hypoventilation and hypokalemia in a patient with poor oral intake in the postanesthesia care unit: A case report.
Anesthesia and Pain Medicine 2012;7(2):170-173
We encountered a case of hypoventilation and hypokalemia in a patient with poor oral intake in the postanesthesia care unit (PACU). A 44-year-old woman underwent a total abdominal hysterectomy under general anesthesia. She was transferred to the PACU after 2 hr of surgery. After 11/2 hr, the patient exhibited hypoventilation, muscle weakness, and mental changes. She was reintubated and transported from the PACU to the intensive care unit. The arterial blood gas analysis results were as follows: pH, 7.27; PaCO2, 65 mmHg; PaO2, 68 mmHg; and serum potassium levels, 2.48 mmol/L. After 6 hr, she recovered with full consciousness.

Pseudohypoparathyroidism (PHP) is a rare clinical syndrome characterized by hypocalcemia, hyperphosphatemia and increase of serum parathyroid hormone in association with unique clinical features. We recently experienced a typical PHP type Ia patient who presented with recurrent seizure and muscle spasms and electroencephalogram (EEG) showed generalized spike-and-wave discharges. With the correction of hypocalcemia, seizures did not recur and epileptiform discharges disappeared. We suggest that the possibility of PHP should be considered in patients with seizures showing hypocalcemia and hyperphosphatemia.

OBJECTIVE: To make a guideline for cytogenetic study and diagnosis through systematic analysis of types and the incidences of chromosomal abnormalities obtained from various types of congenital disorder in Korea. METHODS: The cytogenetic study was performed on 14,402 patients with suspected chromosomal abnormalities at our genetic laboratory of the medical research center between January 1, 1974 to December 31, 2004 and additionally the FISH (Fluorescence in situ hybridization) study was done on 272 patients between January 1, 1998 to December 31, 2004. RESULTS: Total number of case requiring cytogenetic study were 33 in starting year (1974) and by 1983, the number increased rapidly to 481 cases. The number of case was maximum of 894 cases in 1993 and it started to decline from 1996 to 714. Overall chromosomal aberrations were 2,100 cases (14.58%). Autosomal chromosomal abnormalities were 1,257 cases (8.73%). Among those cases, Down syndrome was 848 cases (5.89%), Edward syndrome was 38 cases (0.26%), and Patau syndrome was 6 cases (0.04%) in order of frequency. Sex chromosomal abnormalities were 843 cases (5.85%) in total. Among those cases, Turner syndrome was 527 cases (3.66%), Kleinfelter syndrome was 267 cases (1.85%). Chromosomal abnormality rate in 535 couples with recurrent spontaneous abortions was 5.98% (32 couples). And chromosomal aberration in 1068 cases with primary amenorrhea was 63.95% (683 cases). The diagnostic rate of microdeletion syndrome by FISH method was 22.71%, and marker chromosome was 20.56%. CONCLUSION: From cytogenetic analysis of 14,402 cases performed in single institute during 31 years, we performed a study on the types and the incidences of chromosomal abnormalities. We hope we could suggest a guideline for studies and treatments of congenital disorders in Korea. Along with the cytogenetic study, FISH study was also required.

Almost all reported incidences of herpes simplex virus (HSV) infection in newborns result as a complication of rupture of the amniotic membranes or the delivery of the baby, but infection via the placenta and amniotic membranes is rare. Ventriculomegaly was detected at 36 weeks of gestation by prenatal ultrasonography, and an emergency cesarean section was then performed at 36 weeks of gestation. We report a case of herpes simplex encephalitis detected at 36 weeks of gestation by prenatal ultrasonography, which was confirmed by a postnatal serologic test and CSF test with a brief review of literature.

Malignant fibrous histiocytoma, a type of sarcoma, is a malignant neoplasm with uncertain origin that arises in both the soft tissues and the bone. The occurrence of primary malignant fibrous histiocytoma of the pleura is extremely rare. We report a case of a 65-year-old Korean man who is being diagnosed with primary malignant fibrous histiocytoma of the pleura.

PURPOSE: Porcine proliferative enteropathy (PPE) is known as one of the most important risk factors causing economic losses in swine industry worldwide. This study was conducted to evaluate the efficacy of a commercial oral attenuated Lawsonia intracellularis vaccine (Enterisol Ileitis) against PPE under a commercial pig farm condition in Korea. MATERIALS AND METHODS: Thirty two-day-old 672 piglets were randomly allocated into vaccinated and control groups. All piglets in the vaccinated group were inoculated with a commercial attenuated L. intracellularis vaccine as following the manufacturer's instruction. Body weights of all pigs in both groups were measured on the vaccination day and 6, 14, and 20 weeks post vaccination and an average daily weight gain (ADWG) was calculated. Health status was observed biweekly during the whole trial. RESULTS: The vaccinated group showed significantly higher body weight (p<0.05) and ADWG (p<0.05) than those of the control group. The vaccinated group had significantly reduced impairments in activity, growth, defecation frequency, and stool hardness (p<0.05). Additional health benefits and improved weight gain by the vaccination produced a 4.2:1 return of investment, and the higher gross margin was $4.80 per pig. CONCLUSION: Our finding suggests that the L. intracellularis vaccine program has effects on the substantial health and economic benefits in the Korean swine industry.

Primary adrenocortical carcinoma is a rare tumor, and is characterized by a peri-tumor mass effect and hormone excess signs. Adrenocortical carcinoma most commonly secretes cortisol, but tumors that secrete other adrenal hormones (aldosterone, androgen) are rare. Herein, we report the case of a 70-year-old woman with cortisol, androgen, and aldosterone-secreting adrenal carcinoma. The patient complained of generalized weakness, moon face, and central obesity. On laboratory examination, hypokalemia and metabolic alkalosis was detected. On the hormone test, cortisol, DHEA-S, and aldosterone were all increased. Abdominal CT showed a large right adrenal mass. She underwent right adrenalectomy and the histology revealed the presence of an adrenocortical carcinoma. After adrenalectomy, the patient was treated with hydrocortisone and mitotane.

OBJECTIVE: The object of this study was to evaluate the indications, effectiveness and complications associated with arterial embolization as a safe and effective alternative treatment of obstetrical hemorrhage. METHODS: From September 1998 to October 2005, 42 patients who had a pregnancy related hemorrhage which did not respond to treatment using obstetric maneuvers and uterotonic drugs were included in our study. The patients underwent angiographic embolization for the management of intractable obstetrical hemorrhage at Department of Obstetrics and Gynecology, Yonsei University Medical Center. All available medical records and telephone interviews were reviewed and detailed to collect adequate clinical data such as clinical status, underlying conditions, amount of transfusion, embolization sites, materials of embolization, hospital stay, the success rate and the complications. RESULTS: We have experienced clinically successful embolization in 40 (95.2%) of 42 patients of obstetrical hemorrhage resulting from various causes. After embolization, the patient's vital sign was stabilized. The causes of hemorrhage were atony of uterus (n=17), cervical pregnancy (n=5), abnormal placentation (n=5), laceration of uterine cervix and vagina (n=6). The average amount of blood transfusion was 10.3 unit (range; 0-63 unit). The average duration of hospitalization was 7.4 days (range; 4-18 days). We were able to follow up on 32 patients. The main complications after embolization were hypomenorrhea (n=6), numbness of lower extremities (n=3). In all cases menses resumed spontaneously after procedures. CONCLUSION: The arterial embolization is one of the safe and the effective procedures and offers patients a fertility-preserving alternative to hysterectomy for treatment of intractable postpartum hemorrhage.
