A long nose with a drooping tip is a major aesthetic problem. It creates a negative and aged appearance and looks worse when smiling. In order to rectify this problem, the underlying anatomical causes should be understood and corrected simultaneously to optimize surgical outcomes. The causes of a drooping tip of a long nose are generally classified into two mechanisms. Static causes usually result from malposition and incorrect innate shape of the nasal structure: the nasal septum, upper and lower lateral cartilages, and the ligaments in between. The dynamic causes result from the facial expression muscles, the depressor septi nasi muscle, and the levator labii superioris alaeque nasi muscle. The depressor septi nasi depresses the nasal tip and the levator labii superioris alaeque nasi pulls the alar base upwards. Many surgical methods have been introduced, but partial approaches to correct such deformities generally do not satisfy East Asians, making the problem more challenging to surgeons. Typically, East Asians have thick nasal tip soft tissue and skin, and a depressed columella and alar bases. The authors suggest that multifactorial approaches to static and dynamic factors along with ancillary causes should be considered for correcting the drooping tip of the long noses of East Asians.

Neonatal hemochromatosis is a very rare disorder with an unclear etiology with an extremely poor outcome. We report a case of female newborn who presented with direct hyperbilirubinemia without any evidence of congenital infection, immune related hemolysis or exogenous iron uptake. Diagnostic studies revealed highly elevated ferritin level. T2 weighted image of abdominal Magnetic Resonance Imaging (MRI) showed decreased signal intensity of entire left lobe and a part of right lobe of liver with normal spleen. Liver biopsy showed a large amount of hemosiderin in the hepatocytes and Kupffer cells. All the biochemical and excretory liver functions normalized with conservative managements.

Esophageal candidiasis is an opportunistic infection, often reported in patients who have acquired immune deficiency syndrome (AIDS), a neoplastic disease, or undergoing protracted antibiotic therapy. Impaired cell mediated immunity was often considered as the major predisposing factor in patients of esophageal mucosal colonization of Candida spp. However, it is increasingly reported that the occurrence of esophageal candidiasis with no underlying disease or immune suppression. We have experienced a case of esophageal candidiasis in a 15-year-old girl who was immunologically normal and have no underlying disease and whose main symptoms were epigastric and retrosternal pain with dysphagia. This case suggests the possibilities of candidal infections in children without predisposing factors such as immune compromised conditions, so it will be needed to differentiate the esophageal candidiasis among healthy children with symptoms of odynophagia and dysphagia.

The timely detection of blood-borne pathogens is one of the most important functions of the microbiology laboratory. Recently, methicillin-resistant staphylococci have become the most important pathogens seen by the laboratory. The purpose of this study was to evaluate Staphy agar, a novel screening medium, for the detection methicillin-resistant Staphylococcus aureus, S. epidermidis, or other coagulase-negative staphylococci (CNS) from positive blood cultures showing Gram-positive cocci in clusters. Eighty-six blood cultures that yielded Gram-positive cocci in clusters were included in this study. The organisms were finally identified by the Vitek system, and oxacillin resistance was confirmed by polymerase chain reaction (PCR)-based mecA gene detection. The identification and oxacillin resistance of all S. aureus strains showed complete agreement with the Vitek and PCR results. The presumptive detection of S. epidermidis and other CNS were consistent with the Vitek system in 94.7%, and the screening of oxacillin resistance was consistent with the result of PCR in 92.1% of 38 strains. The Staphy agar method is reliable and rapid for differentiating Gram-positive cocci in clusters in blood and for determining their methicillin resistance.

6.Treatment of delayed venous congestion of the nipple-areolar complex after reduction mammoplasty

Reduction mammoplasty is a popular operation worldwide. Early complications include bleeding, wound dehiscence, and nipple-areolar complex (NAC) ischemia. Although uncommon, NAC ischemia can lead to necrosis of the NAC. NAC congestion is usually recognized intraoperatively or within a few hours of the operation. A 21-year-old woman with severe macromastia received bilateral reduction mammoplasty using a Wise-pattern reduction with a superomedial pedicle. NAC congestion of the left breast was identified 40 hours after the operation. Delayed venous congestion of the NAC after reduction mammoplasty has not been previously reported; in this case, delayed congestion may have been caused by partial venous obstruction aggravated by the progression of tissue edema near the pedicle. Through use of the delayed suture technique, application of nitroglycerin cream, intravenous administration of prostaglandin E1, and use of a portable negative-pressure wound therapy device, the patient’s NAC was salvaged with satisfactory nipple projection and minimal scarring.
8.Successful umbilicus salvage following concurrent infraumbilical single-port myomectomy and free transverse rectus abdominis myocutaneous flap elevation: a case report

Performing a concurrent gynecologic operation and mastectomy with immediate breast reconstruction using a free transverse rectus abdominis myocutaneous flap may increase the risk of complications such as umbilical necrosis due to vascular compromise. Imaging studies such as preoperative computed tomography angiography and intraoperative indocyanine green testing can provide information regarding the umbilical blood supply, facilitating decision-making for pedicle selection. Therefore, in situations where a coordinated operation is unavoidable, a thorough preoperative and intraoperative evaluation of the umbilical blood supply is recommended to avoid complications.

Region specific brain organoids are brain organoids derived by patterning protocols using extrinsic signals as opposed to cerebral organoids obtained by self-patterning. The main focus of this review is to discuss various region-specific brain organoids developed so far and their application in modeling neurodevelopmental disease. We first discuss the principles of neural axis formation by series of growth factors, such as SHH, WNT, BMP signalings, that are critical to generate various region-specific brain organoids. Then we discuss various neurodevelopmental disorders modeled so far with these region-specific brain organoids, and findings made on mechanism and treatment options for neurodevelopmental disorders (NDD).

Orthognathic surgeries often utilize rigid fixation for stabilization of the osteotomy site. The longterm fate of rigid fixations is still under investigation, and whether they should be routinely removed is under debate despite their low complication rates. Here, we report a case where a 26-year-old man suffered high-velocity trauma to his face 7 years after a two-jaw surgery. Computed tomography examination revealed a zygomaticomaxillary complex fracture, and open reduction and internal fixation was performed along with anterior maxillary wall reconstruction using absorbable mesh. Intraoperative examination revealed a broken L-shaped titanium plate near the fracture site with multiple bony fragments near each titanium screw. The rigid titanium system may have caused comminution of the fracture pattern, worsening the severity of the fracture.
