Atypical hemolytic uremic syndrome (aHUS), a rare form of thrombotic microangiopathy, is distinguished from the typical form by the absence of a preceding verotoxin-producing Escherichia coli infection. Notably, aHUS occurs in association with genetic or acquired disorders causing dysregulation of the alternative complement pathway. Patients with aHUS may show the presence of anti-complement factor H (CFH) autoantibodies. This acquired form of aHUS (antiCFH-aHUS) primarily affects children aged 9-13 years. We report a case of a 13-year-old Lao girl with clinical features of aHUS (most likely anti-CFH-aHUS). The initial presentation of the patient met the classical clinical triad of thrombotic microangiopathy (microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney injury) without preceding diarrheal illness. Low serum levels of complement 3 and normal levels of complement 4 indicated abnormal activation of the alternative complement pathway. Plasma infusion and high-dose corticosteroid therapy resulted in improvement of the renal function and hematological profile, although the patient subsequently died of infectious complications. This is the first case report that describes aHUS (possibly anti-CFH-aHUS) in Laos.

We report two rare cases of spontaneously regressed Rathke's cleft cyst (RCC). A 52-year-old woman presented with headache. A pituitary hormone study was normal. Brain magnetic resonance imaging (MRI) showed a $0.45-cm^3$ cystic sellar lesion. The cyst was hyperintense on T1-weighed imaging and hypointense on T2-weighted imaging without rim enhancement, comparable to a RCC. Six months later, brain MRI showed no change in the cyst size. Without any medical treatments, brain MRI 1 year later revealed a spontaneous decrease in cyst volume to $0.05cm^3$. A 34-year-old woman presented with headache and galactorrhea lasting 1 week. At the time of the visit, the patient's headache had disappeared. Her initial serum prolactin level was 81.1 ng/mL, and after 1 week without the cold medicine, the serum prolactin level normalized to 11.28 ng/mL. Brain MRI showed a RCC measuring $0.71cm^3$. Without further treatments, brain computed tomography 6 months later showed a spontaneous decrease in cyst volume to $0.07cm^3$. Another 6 months later, brain MRI revealed that the cyst had remained the same size. Neither patient experienced neurological symptoms, such as headache or visual disturbance, during the period of cyst reduction. The RCCs in both patients underwent spontaneous regression without any medical treatment during a period of 6 months to 1 year. Although spontaneous regression of a RCC is rare, it is still possible and a sufficient follow-up period should be considered.

Chylothorax is a rare disease and massive lymph fluid loss can cause life-threatening condition such as severe malnutrition, weight loss, and impaired immune system. If untreated, mortality rate of chylothorax can be up to 50%. This is a case report of a 3-year-old child with iatrogenic chylothorax. Despite conservative treatment and procedures, like perm catheter insertion, the patient failed to improve the respiratory symptoms over 3 months of period. As an alternative to surgical option, such as pleurodesis and thoracic duct ligation which has high complication rate, the patient underwent lymphovenous anastomosis (LVA) and lymph node to vein anastomosis (LNVA). Follow-up at fourth month showed clear lungs without breathing difficulty despite perm catheter removal. This is the first report to show the effectiveness of LVA and LNVA against iatrogenic chylothorax.

High-grade serous carcinoma (HGSC) is the most common type of pelvic cancer among women. Serous tubal intraepithelial carcinoma (STIC) is a precursor lesion of HGSC. Herein, we report a rare occurrence of STIC in patients undergoing surgery for benign indications without a family history of ovarian cancer. A 77-year-old woman underwent total laparoscopic hysterectomy and bilateral salpingo-oophorectomy for uterine prolapse. Pathological examination revealed bilateral STIC without ovarian abnormalities, and no other abnormal findings were noted. Another patient, a 49-year-old woman, underwent laparoscopic total hysterectomy and bilateral salpingectomy for uterine fibroids. STIC lesions were observed in both fallopian tubes. Subsequently, a staging was performed. No additional lesions were found, and the patient was followedup through imaging and blood tests. As reports of STIC lesions are rare, data on their clinical outcomes and management strategies are limited. In this report, we present cases of incidental STIC in benign surgery and discuss its proper interpretation and management. Through the early detection of STIC lesions, patients with risk factors can be identified in advance, which will allow prevention and early detection of ovarian cancer. Opportunistic salpingectomy was also actively discussed in this regard.

A 25-year-old man returned to Seoul National University Children's Hospital with mild dyspnea on exertion. He had undergone an arterial switch operation at 1 month after birth to correct a complete transposition of the great arteries and a ventricular septal defect. When the patient was 15 years old, dilatation of the neo-aortic sinus and annulus was first identified; since then, it had gradually increased. Given the young age of the patient and the degree of aortic regurgitation (AR), which was mild to moderate, we opted to perform a valve-sparing neo-aortic root replacement with aortic valve repair. Postoperative echocardiography showed successful reductions in the sizes of the aortic sinus and annulus, with only mild AR remaining.

Postoperative atlantoaxial rotatory subluxation (AARS) is a rare complication that develops almost exclusively in children following oropharyngeal and otologic surgeries, proposing that oropharyngeal inflammatory responses and excessive head rotation are responsible factors. However, there have been no reports of AARS after excision of a nevus on the head and neck. Here, we present two cases of AARS following limited head rotation during simple nevus excision. Patient 1, a 9-year-old girl, complained of neck pain and limited range of motion after excision of the nevus on the neck. After 2 months, computed tomography and magnetic resonance imaging finally revealed AARS with a ruptured transverse atlantal ligament. A month of halo traction was required for the treatment. Patient 2, an 11-year-old girl, presented with immediate pain and limited neck extension after tissue expander insertion under the upper chest and excision of the nevus on her left cheek. The diagnosis was promptly made using cervical spine radiography. A cervical collar was applied for 1 month. Both patients recovered without any complications after treatment. This report highlights the importance of suspicion for AARS after surgery regardless of surgical duration or amount of head rotation.

This case report presents 2 patients with gastroesophageal junction cancer who both underwent totally minimally invasive esophagectomy with colon interposition. Patients 1 and 2, who were 43-year-old and 78-year-old men, respectively, had distinct clinical presentations and medical histories. Patient 1 underwent minimally invasive robotic esophagectomy with a laparoscopic total gastrectomy, colonic conduit preparation, and intrathoracic esophago-colono-jejunostomy. Patient 2 underwent completely robotic total gastrectomy, colon conduit preparation, and intrathoracic esophago-colono-jejunostomy. The primary challenge in colon interposition is assessing colon vascularity and ensuring an adequate conduit length, which is critical for successful anastomosis. In both cases, we used indocyanine green fluorescence angiography to evaluate vascularity. Determining the appropriate conduit is challenging; therefore, it is crucial to ensure a slightly longer conduit during reconstruction. Because totally minimally invasive colon interposition can reduce postoperative pain and enhance recovery, this surgical technique is feasible and beneficial.

코로나바이러스-19 (COVID-19)는 일반적으로 성인에 비해 소아에서 임상적으로 경한 양상을 보이며, 대부분의 소아에서 약 7일간의 격리가 끝나면 증상이 호전되어 특별한 이벤트 없이 퇴원하게 된다. 우리는 통상적인 임상경과와는 다르게, 격리 해제시점 또는 퇴원을 고려하고 있는 시점에 갑자기 악화된 임상증상을 보이는 3명의 청소년 환아들을 경험하였다. 세 명의 아이들은 공통적으로 신경학적 질환을 기저질환으로 가지고 있었다. Case 1은 울리히 선천성 근디스트로피로 진단받고 밤에만 이중양압기로 호흡보조를 받던 17세 남환의 경우로, 첫 COVID-19 증상 이후 9일이 지나고 증상 호전되어 퇴원을 준비하던 중 심폐정지가 발생하였다. Case 2는 뇌출혈 및 뇌경색 이후 병상에 누워 지내며 기관절개관 삽입 후 가정용 인공호흡기로 호흡보조를 받던 12세 여자 환아로, 증상이 호전되어 퇴원하였으나 첫 COVID-19 증상 이후 11일이 지난 후 심폐정지가 발생하였다. Case 3의 경우 조산아로 출생하여 뇌실출혈 및 수두증 진단받고 병상에 누워 지내나 호흡보조는 받지 않았던 12세 남자 환아로, 첫 증상 이후 호전추세였으나 10일 후 다기관 기능부전 확인되어 입원 진행하였다. 항바이러스제, 스테로이드제, 경험적 항생제가 투여되었고 중환자실 치료를 시행하였다. 세 환아들 중 2명 (case 1, 3)은 치료를 통해 호전되었으나, 1명 (case 2)는 심부전 진행하여 사망하였다. 이러한 경험에 비추어 볼 때, COVID-19 격리 기간이 끝나고 퇴원 가능한 시점이라도 갑작스러운 증상 악화를 보일 가능성이 있기에, 긴장을 놓지 않고 임상 증상의 변화를 확인하고 필요시 빠른 조치를 취해야 할 것으로 생각된다. 특히 신경학적 또는 호흡기적 만성 질환을 갖는 아이들에게 주의가 더 필요할 것으로 생각된다.

Objectives : This study describes a plan that was designed to prevent a measles outbreak that showed a changed outbreak pattern. This study is based on the epidemiological investigation of a measles outbreak in a preschool in Incheon, Korea, 2006. Methods : The subjects were 152 students at a preschool where a measles outbreak occurred. A questionnaire survey was conducted and serological testing for measles-specific IgM was preformed. Results : Of the fifteen confirmed, identified cases, eleven patients had been vaccinated with one dose, one patient had received two doses and three patients were unvaccinated. The three unvaccinated cases consisted of one 5-year-old child, one 3-year-old child and one 16-month-old infant. For the cases with one dose of the vaccination, there were 11 cases, which consisted of six 5-year-old children, two 4-year-old children, two 3-year-old children and one 2-year-old child. The case with two doses of the vaccination was one 4-year-old child. The attack rate of measles was 100% in the 0-dose group, 11.2% in the 1-dose group and 2.0% in the 2-dose group. The vaccine's efficacy was 88.8% in the 1-dose group and 98.0% in the 2-dose group. The vaccine effectiveness for the 2-dose group was higher than that of the 1-dose group. Conclusions : High coverage with a 2-dose vaccination should be maintained, and the vaccination should be given at the suitable time to prevent a measles outbreak with a changed outbreak pattern.
