BACKGROUND: We compared the clinical outcomes of cardiac valve surgery in adult Jehovah's Witness patients refusing blood transfusion to those in non-Jehovah's Witness patients without any transfusion limitations. METHODS: From 2005 to 2014, 25 Jehovah's Witnesses (JW group) underwent cardiac valve surgery using a blood conservation strategy. Twenty-five matched control patients (non-JW group) were selected according to sex, age, operation date, and surgeon. Both groups were managed according to general guidelines of anticoagulation for valve surgery. RESULTS: The operative mortality rate was 4.0% in the JW group and 0% in the non-JW group (p = 1.000). There was no difference in postoperative major complications between the groups (p = 1.000). The overall survival rate at 5 and 10 years was 85.6% ± 7.9% and 85.6% ± 7.9% in the JW group, respectively, and 100.0% ± 0.0% and 66.7% ± 27.2% in the non-JW group (p = 0.313). The valve-related morbidity-free survival rates (p = 0.625) and late morbidity-free survival rates (p = 0.885) were not significantly different between the groups. CONCLUSIONS: Using a perioperative strategy for blood conservation, cardiac valve surgery without transfusion had comparable clinical outcomes in adult patients. This blood conservation strategy could be broadly applied to major surgeries with careful perioperative care.

The autoinfective filariform larva of Strongyloides stercoralis causes hyperinfection in immunosuppressed hosts. Here we report on the case of a male patient who was admitted to the emergency room at Gwangju Veterans Hospital with a complaint of dyspnea, and who was receiving corticosteroid therapy for asthma. Many slender larvae of S. stercoralis with a notched tail were detected in Papanicolaou stained sputum. They measured 269 +/- 21.2 micrometer in length and 11 +/- 0.6 micrometer in width. The esophagus extended nearly half of the body length. The larvae were identified putatively as autoinfective third-stage filariform larvae, and their presence was fatal. The autoinfective filariform larva of S. stercoralis has not been previously reported in Korea.

BACKGROUND: Little is known concerning hair diameter variation within the safe donor area for hair transplantation surgery. Thicker or thinner hair may be needed, depending on the recipient area, hairline design, and the purpose of surgery. METHODS: Twenty-seven patients (7 men and 20 women; mean age, 28 years; range, 20–47 years) were included in this study. The midoccipital point was used as the reference point on the horizontal plane at the upper border of the helical rim. The target area width was 15 cm (7.5 cm to the right and left of the reference point) and the height was 8 cm (2 cm above and 6 cm below the reference point). The study area was divided horizontally into 3 5-cm sections (A, B, C) and vertically into 4 2-cm sections (1–4), creating a total of 12 zones. Ten anagen hairs were randomly obtained from each zone and their diameters were measured. RESULTS: Hair diameter in the 4 vertical sections varied significantly, gradually decreasing from sections 1 (superior) to 4 (inferior) in all 3 horizontal sections (A, B, and C). CONCLUSIONS: Our results suggest that sections 1 and 2 of the occipital safe donor area would be useful for obtaining thicker hair, such as in procedures to treat male- and female-pattern hair loss, whereas hair from zones 3 and 4 could be useful for transplantation surgery requiring thinner hair, such as eyebrows, eyelashes, and female hairline correction. Our results may be clinically valuable for planning hair transplant surgery and choosing the optimal donor region.

Orbital tuberculosis is a rare form of extrapulmonary tuberculosis, even in endemic areas. It may involve the soft tissue, lacrimal gland, periosteum, or bones of the orbital wall. We present a case of orbital tuberculosis on the lower eyelid. An 18-year-old woman with no underlying disease visited our clinic for evaluation of an oval nodule (1.5× 1.2 cm) on the right lower eyelid. Incision and drainage without biopsy was performed 2 months ago in ophthalmology department, but the periorbital mass had deteriorated, as the patient had erythematous swelling, tenderness, and cervical lymphadenopathy. Visual acuity was normal; there were no signs of proptosis, diplopia, or ophthalmoplegia. Computed tomography revealed a small abscess cavity without bony involvement. We performed an excision and biopsy through a percutaneous incision under local anesthesia. Histological examination revealed a granuloma and was diagnosed as orbital tuberculosis. The patient was additionally treated with anti-tuberculosis therapy for 6 months and recovered without complication or recurrence by 7 months. Orbital tuberculosis occurs in patients with or without associated pulmonary tuberculosis, and should be considered as a differential diagnosis in patients with inflammatory orbital disease and an orbital mass. If recurrence occurs despite adequate initial treatment, we recommend an additional examination and excisional biopsy.

Indication for extracorporeal membrane oxygenation (ECMO) has been extended as the experience of ECMO in various clinical settings accumulates and the outcome after ECMO installation improves. We report two cases of successful mitral valve surgery for severe ischemic mitral regurgitation in patients on ECMO support for cardiogenic shock which developed upon coronary angiography.

OBJECTIVE: Selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), and noradrenergic and specific serotonergic antidepressant (NaSSA) are extensively used to treat the patients with depression. Although depressed patients are complaining of somatic pain as a complication of depression, there has not been any straight-forward comparative data of the effect of SSRIs, SNRIs, and NaSSA on pain. Therefore, in this study, we tried to figure out the effect of each drug i.e.SSRIs, SNRIs, and NaSSA, on pain by administrating each drug to three different groups of patient with depression. METHODS: We conducted a chart review of patients, who visited a university hospital. From January, 2010 to February, 2012, total 150 inpatients who had been diagnosed as major depression by Diagnostic and Statistical Manual of Mental Disorders-4th edition criteria, and administered any of three drugs [SSRIs (n=50), SNRIs (n=50), and NaSSA (n=50)] at least for fore weeks in the department of psychiatry in Chung-Ang University Hospital, were enrolled for this study. We compared and analyzed depressive symptoms and pain between three groups. Depressive symptoms and pain were evaluated by Korean version of the Hamilton Depression Rating Scale and visual analogue scale at baseline and fore weeks later. RESULTS: There was no difference in the age, gender, severity of depression and pain among three groups. However, there was difference in 50% depressive symptomatic improvement rate in the following four weeks among three groups. The number of patient found to achieve 50% symptomatic improvement in SSRIs, SNRIs, and NaSSA group was 17 (34%), 20 (40%), and 34 (54%) in each group, respectively, indicating significantly higher improvement rate in NaSSA compared to SSRIs. During four weeks of administration period, significant difference in 50% pain improvement rate was observed among three groups. The number of patient found to achieve 50% pain improvement in SSRIs, SNRIs, and NaSSA group was 14 (28%), 20 (40%), and 27 (54%) in each group, respectively, showing twice higher pain improvement rate in NaSSA compared to SSRIs. CONCLUSION: This result indicates better efficacy of NaSSA on pain improvement compared to SSRIs, and SNRIs in depressed patients. Although the effect of pain improvement has been mainly focused on SNRIs, result from this study suggests the need for further research and validation on the effect of NaSSA for pain control.

The 64-year-old female patient with cough and intermittent hemoptysis of six months duration visited our hospital. On chest computed tomography, a small, ovoid, 1.3cm sized and well enhanced lesion was detected on the distal trachea. Two multiple lobulated lesions on the sigmoid and transverse colon were revealed on the colonoscopy. The histological findings showed small and medium sized lymphocytes infiltration, CD20 and CD79a positive staining and multiple lymphoepithelial lesions on the distal trachea and colon tissues. Herein, a case of primary MALT lymphoma, with involvement of the trachea and colon, which was treated with rituximab (CD20 anti-monoclonal antibody), cyclophosphamide, adriamycin, vincristine and prednisolone (CHOP regimen), is reported.
