In this report, we present a scalp defect reconstruction with lateral arm free flap. We highlight the difficulty in obtaining a recipient vein and the venous drainage managed through an open end of the donor vein. A 52-year-old woman presented with a pressure sore on the left scalp. A lateral arm free flap was transferred to cover this $8{\times}6cm$ defect. The arterial anastomosis was successful, but no recipient vein could be identified within the wound bed. Instead, we used a donor venous end for the direct open venous drainage. In order to keep this exposed venous end patent, we applied heparin-soaked gauze dressing to the wound. Also, the vein end was mechanically dilated and irrigated with heparin solution at two hour intervals. Along with fluid management and blood transfusion, this management was continued for the five days after the operation. The flap survived well without any complication. Through this case, we were able to demonstrate that venous congestion can be avoided by drainage of the venous blood through an open vessel without the use of leeches.

Purpose: Aplasia Cutis Congenita (ACC) is a rare disease characterized by the focal defect of the skin at birth, frequently involving scalp, but it may affect any region of the body. There are no etiology known but some conditions such as intrauterine vascular ischemia, amniotic adherences and viral infections are associated. The ideal treatment for the ACC is not known. Superficial and relatively small sized defects (< $3{\times}5\;cm$) may heal spontaneously and large defects related with risks of infection and bleeding may require aggressive surgical treatment. Hyalomatrix$^{(R)}$ is a bilayer of an esterified hyaluronan scaffold beneath a silicone membrane. It has been used as a temporary dermal substitute to cover deep thickness skin defect and has physiological functions derive from the structural role in extracellular matrix and interaction with cell surface receptor. This material has been used for the wound bed pre-treatment for skin graft to follow and especially in uncooperative patient, like a newborn, this could be a efficient and aseptic way of promoting granulation without daily irritative wound care. For this reason, using Hyalomatrix$^{(R)}$ for the treatment of ACC was preferred in this paper. Methods: We report a case of a newborn with ACC of the vertex scalp and non-ossified partial skull defect. The large sized skin and skull defect ($6{\times}6\;cm$) was found with intact dura mater. No other complications such as bleeding or abnormal neurologic sign were accompanied. Escharectomy was performed and Hyalomatrix$^{(R)}$ was applied for the protection and the induction of acute wound healing for 3 months before the split-thickness skin graft. During the 3 months period, the dressing was renewed in aseptic technique for every 3 weeks. The skin graft was achieved on the healthy granulation bed. Results: The operative procedure was uneventful without necessity of blood transfusion. Postoperative physical examination revealed no additional abnormalities. Regular wound management was performed in out-patient clinic and the grafted skin was taken completely. No other problems developed during follow-up. Conclusion: Hyalomatrix$^{(R)}$ provides protective and favorable environment for wound healing. The combination of the use of Hyalomatrix$^{(R)}$ and the skin graft will be a good alternative for the ACC patients with relatively large defect on vertex.

The authors aimed to analyze the quality improvement efficiency of wound dressing with 2-octyl cyanoacrylate(2-OCA) in stereotactic image guided linear or sigmoid incisions in a cohort of consecutive craniotomy patients, and to compare clinical results with those of iodine-dressing and silk sutured patients underwent conventional craniotomy surgery with large pedicle flap incisions without stereotactic guidance. In methods, 26 patients were involved as the study group at one hospital. We retrospectively compared their results with those of 38 consecutive control patients at the same unit. The suggested new medical material, 2-octyl cyanoacrylate(2-OCA), resultantly decreased or prevented the contaminated fluid influx from scalp outside. The mean infection rate for the control group (7.89%) was relatively higher than that of the study group (3.85%). In addition, the use of stereotactic image guided craniotomy was significant to reduce operation time, to simplify operative procedures and to decrease potential risk factors.

Studies of interictal epileptiform discharges are essential for improving the diagnosis, classification, and management of epilepsy. In this case series we sought to identify the clinical and neurophysiological significance of bifid spikes, whose pattern bears a strong resemblance to the cardiac M pattern. We hypothesize that, analogous to the cardiac M pattern, the cerebral M pattern is generated by a conduction defect associated with asynchronous spatiotemporal averaging of electrical signals in the cortex, resulting in the signals reaching the scalp with different latencies. Unlike the cardiac M pattern, the pathology underlying the cerebral M pattern is unknown, although congenital CNS anomalies may be a culprit.

Angiosarcoma is a very rare soft tissue sarcoma that originates from endothelial cells and typically has a poor prognosis. It is most commonly found in elderly white men and can occur anywhere in the body, particularly in the head, neck, and scalp. Patients who have undergone previous radiation treatment or who have chronic lymphedema also face an elevated risk of this condition. Various genetic changes are suspected to contribute to the development of angiosarcoma, and these changes have been identified as potential targets for treatment. For localized disease, wide surgical resection is often the prudent course of action. A multidisciplinary approach, which may include surgery, radiotherapy, systemic chemotherapy, or immunotherapy, is typically the most effective way to achieve favorable outcomes. In this review, we discuss the general understanding of angiosarcoma and its management, with a particular focus on the current evolving treatments for the disease.

Greying of hairs or Canities (Sheeb) is a hair disorder characterized by premature graying of scalp hair, beard, moustache etc. In Unani system of medicine (USM), the causes of premature greying of hairs, concept behind graying of hairs, principles of treatment, preparations that prevent premature greying of hairs, regimen, systemic and local treatment to stimulate pigmentation and the most interesting point is the use of different type of hair dyes (khizabat) is all illustrated. Classical texts described black, red, blond and white hair dye preparations with formulae and method of use. Initially for the hair graying management, utilizing simple and complex substances from plants, minerals, metals and mixture of these was the main method, which satisfied the desire to change the colour of the hair. With the advancement in chemical science, dyes formulaes, method of formation and application are changed. But due to the awareness about demerits of chemical dyes, people are looking back towards the natural ways to combat hair greying and herbal hair dye is an alternative. This paper is an overview of Unani drugs of local and internal use for hair greying with special attention towards herbal dyes. Most commonly used herbs in khizaab with their actions and constituents has been summarized. This is an effort to globalize the benefits of Unani herbs in hair greying problem. In short, International demand for hair dyes has been steadily growing and there is a wide scope for exploring different aspects of hair greying treatment and dyes in USM.

Acute viral meningitis and myositis are rare complications of varicella-zoster virus (VZV) reactivation. A 71-years-old immunocompetent man, who presented with lower back pain radiating to the left lower extremities, developed vesicles on the L5 dermatomal area. The next day, he had complained of aberrant vesicles on the trunk, face and scalp, with generalized myalgia, headache and dizziness. He was confirmed with VZV meningitis and myositis, as demonstrated by the presence of VZV DNA in the blood and cerebral spinal fluid using a polymerase chain reaction (PCR) amplification. PCR has been used in patients with a VZV infection associated neurological symptoms, and provides a useful tool for the early diagnosis of VZV-associated neurological disease. The patient was treated with bed rest, with intravenous acyclovir for the VZV infection, and intravenous Patient-controlled Analgesia for pain management and the prevention of postherpetic neuralgia. When he visited the outpatient department 3 months later, the skin lesion, leg pain, headache and myalgia had all improved, without sequelae. Here, this case is reported, with a discussion of the relevant literature on its diagnosis and management.

The customer of massage chair is expanding day by day from middle age to all ages. In 2018, the market size was 700 billion KRW, an increase of 30 times over 10 years. However, most related SMEs suffer from excessive competition by the market monopoly of some major companies. In this situation, in order for a related company to survive, it is necessary to steadily research and develop new products. Founded in 2009, company L produces massage chairs for health and relaxation of customers. L's products use a sound wave vibration module that is favorable for human body, unlike other products that use vibration motor type. However, frequent breakdowns of massage chair due to the vulnerability of plate (leaf) springs, which play an important role in sound wave vibration modules, made sap its competitiveness. In this paper, we propose a method to design desirable plate spring structure by sequentially experimenting with five different plate springs. The results of this study are expected to contribute to improve the quality of plate spring and the reliability of sound wave vibration module. In the future, it is necessary to find a way to use it in the development of foot massage or scalp management device as well as continuous research to find optimal plate spring structure through various analysis.
