3.Neck circumference and incidence of cerebrovascular disease over 12 years among Korean adults
Osong Public Health and Research Perspectives 2022;13(1):71-79
Neck circumference is associated with a distinctive fat storage process that confers additional metabolic risk. Hence, this study aimed to investigate the correlation between baseline neck circumference and the incidence of cerebrovascular disease using a prospective community-based sample of Korean adults over 12 years of follow-up, after controlling for selected covariates. Methods: Participants with non-cerebrovascular disease were divided into 4 groups (Q1–Q4) based on their baseline neck circumference. Cox proportional hazards analysis was used to calculate hazard ratios and 95% confidence intervals (CIs) to evaluate the relationship between neck circumference and cerebrovascular disease incidence over a 12-year period. Results: Among this study’s 3,662 participants, 128 (3.50%) developed cerebrovascular disease. The incidence of cerebrovascular disease increased from 2.2% in Q1 to 4.3% in Q2, 2.5% in Q3, and 5.0% in Q4. When compared to Q1, the relative risks of cerebrovascular disease development were 0.57 (95% CI, 0.25–1.31), 0.86 (95% CI, 0.38–1.96), and 0.79 (95% CI, 0.30–2.07) in man and 1.86 (95% CI, 0.66–5.20), 3.50 (95% CI, 1.25–9.86), and 4.71 (95% CI, 1.50–14.77) in woman in Q2, Q3, and Q4, respectively, after adjusting for most risk factors related to cerebrovascular disease. Conclusion: The relationship between neck circumference and cerebrovascular disease was stronger in woman than in man, indicating potential differences between the sexes. These results are meaningful for evaluating and surveilling neck circumference as a promising tool for identifying subgroups of vulnerable and at-risk populations.

Morgellons disease is a rare disease with unknown etiology. Herein, we report the first case of Morgellons disease in Korea. A 30-year-old woman presented with a 2-month history of pruritic erythematous patches and erosions on the arms, hands, and chin. She insisted that she had fiber-like materials under her skin, which she had observed through a magnifying device. We performed skin biopsy, and observed a fiber extruding from the dermal side of the specimen. Histopathological examination showed only mild lymphocytic infiltration, and failed to reveal evidence of any microorganism. The polymerase chain reaction for Borrelia burgdorferi was negative in her serum.

As the mitral valve disease becomes long-standing, the patient may develop pulmonary hypertension. It was reported that after surgical correction, the elevated pulmonary vascular resistance(PVR) would fall quickly in association with the fall in left atrial pressure(LAP). This study was performed to evaluate the changes in mean pulmonary artery pressure(PAP) and PVR immediately after mitral valve replacement(MVR). Fifty six patients undergoing mitral valve replacement(MVR) were divided into two groups on the basis of the presence or absence of significant pulmonary hypertension, defined as a resting mean pulmonary arterial pressure greater than 30mmHg. After induction of anesthesia, PAP, PVR, cardiac output(CO) were measured and compared with values in postbypass period. PAP and PVR were significantly decreased(PAP from 39.64+/-1.88 to 29.18+/-1.65 mmHg, P 0.001, PVR from 6.16+/-1.14 to 3.53+/-0.62 units, P<0.05) in Group II(PAP> or = 30mmHg, n=23), whereas not changed in Group I(PAP30 mmHg, n=33)(P<0.05). Persistance of an elevated PVR may cause right ventricular failure and low-output syndrome, so that an attempt to reduce the PVR is needed postoperatiavely. This study demonstrated that the PAP and PVR fall significantly after MVR especially in patients with severe pulmonary hypertension.

PURPOSE: Despite the increasing use of continuous renal replacement therapy (CRRT) in the neonatal intensive care unit (NICU), few studies have investigated its use in preterm infants. This study evaluated the prognosis of preterm infants after CRRT and identified risk factors of mortality after CRRT. MATERIALS AND METHODS: A retrospective review was performed in 33 preterm infants who underwent CRRT at the NICU of Samsung Medical Center between 2008 and 2017. Data of the demographic characteristics, predisposing morbidity, cardiopulmonary function, and CRRT were collected and compared between surviving and non-surviving preterm infants treated with CRRT. Univariable and multivariable analyses were performed to identify factors affecting mortality. RESULTS: Compared with the survivors, the non-survivors showed younger gestational age (29.3 vs. 33.6 weeks), lower birth weight (1359 vs. 2174 g), and lower Apgar scores at 1 minute (4.4 vs. 6.6) and 5 minutes (6.5 vs. 8.6). At the initiation of CRRT, the non-survivors showed a higher incidence of inotropic use (93% vs. 40%, p=0.017) and fluid overload (16.8% vs. 4.0%, p=0.031). Multivariable analysis revealed that fluid overload >10% at CRRT initiation was the primary determinant of mortality after CRRT in premature infants, with an adjusted odds ratio of 14.6 and a 95% confidence interval of 1.10–211.29. CONCLUSION: Our data suggest that the degree of immaturity, cardiopulmonary instability, and fluid overload affect the prognosis of preterm infants after CRRT. Preventing fluid overload and earlier initiation of CRRT may improve treatment outcomes.

Sarcoidosis is a rare multisystemic granulomatous disease. The lungs, lymph nodes, eyes, skin and liver are the most commonly involved. There are two distinct forms of sarcoidosis in children. One is early-onset(younger) childhood sarcoidosis characterized by skin rash, uveitis, and arthritis occurring before age 4 years. The other is late-onset(older) childhood sarcoidosis characterized by involvement of the lungs, the common radiographic finding is bilateral hilar lymph node enlargements, similar to the adult manifestation. We report a case of late-onset childhood sarcoidosis in a 6-year-old girl which is the first pediatric pulmonary sarcoidosis reported in Korea.

Acute phlegmonous gastritis is an uncommon disease, often fatal condition characterized by suppurative bacterial infection of the gastric wall. It has a high mortality rate mainly because the diagnosis is usually made late. Until recently, gastrectomy in combination with antibiotics was recommended. We had experienced a case of 66-year-old man presented with epigastric pain, nausea, vomiting, and hematemesis, followed by aspiration pneumonia. At upper gastrointestinal endoscopy, the gastric lumen was narrow, and the mucosa was severely inflamed, which was erythematous, swelled, and showed necrotic areas covered with purulent exudate. Klebsiella oxytoca and Acinetobacter lwoffii were isolated in the gastric tissue culture. Contrast-enhanced computerized tomography scan of abdomen demonstrated diffuse gastric wall thickening and an intramural abscess in the gastric antral wall. Although delayed gastric emptying by gastroparesis prolonged the in-hospital period, the only medical treatment with antibiotics alone successfully cured the patient without gastrectomy.

Nevus Sebaceus is a hamartoma that has a well-documented neoplastic potential. Multiple tumors may occasionally arise, but the coexistence of 3 or more tumors is extremely rare. We report a case of nevus sebaceus in a 55-year-old female associated with syringocystadenoma papilliferum, trichoblastoma, basal cell carcinoma, sebaceous adenoma and sebaceous epithelioma.
