1.Biomarkers of adult asthma and personalized medicine.
Allergy, Asthma & Respiratory Disease 2016;4(1):4-13
The concept of personalized medicine for disease diagnosis, treatment, and management, considering individual variability, including susceptibility, clinical manifestations, and drug responsiveness, is a global emerging trend in medicine, which is also inevitable. However, clinical applications of personalized medicine in the real-world practice have been limited to certain cancers so far. Furthermore, this new concept to the diagnosis and treatment of adult asthma has not been applied to clinical use. Asthma is a multifactorial and heterogeneous disease. It seems to encompass a broad spectrum of clinical manifestations with different underlying pathophysiological mechanisms. Thus, it is not easy to categorize by their clinical features alone. Endotypical categorization that considering specific pathophysiological mechanisms will be more helpful in applying the concept of personalized medicine. The success of personalized medicine depends on patient selection for precise prescription of asthma medications. In the recent years, many investigators and physicians have devoted a lot of effort to the discovery of reliable biomarkers in asthmatic patients, which will be able to actualize the personalized medicine in near future. Despite such great efforts toward investigation of good biomarkers, few things have turned out to be practical in the clinic. Easily interpretable biomarkers of asthma are necessary to assess early detection, determination of treatment, prognosis prediction, and monitoring of exacerbation. Herein, we review recent studies regarding disease classifications and biomarkers of asthma.

Spontaneous lateral sphenoid cephalocele (SLSC) is the herniation of intracranial contents through a bony defect in the lateral sphenoid, without predisposing factors. SLSC pathogenesis is associated with idiopathic intracranial hypertension (IIH); however, the relationship between IIH and SLSC is not fully understood due to the limited number of published case reports. Here, we report a unique case of SLSC in a 39-year-old female who presented with a combination of a lateral sphenoid cephalocele and multiple radiologic findings indicative of IIH, some of which have never been described in previously published case reports. This case highlights the possibility that chronically elevated intracranial pressure may be a determining factor in SLSC development.

We report a very rare case of unilateral blepharoptosis and swelling as an unusual complication of a filler injection. The patient received a filler injection into the forehead 4 years previously by an unlicensed practitioner. In the operation, an encapsulated yellowish cyst with inflammation was found to be adhered to the orbital septum and was excised. To prevent additional inferior migration of the remaining foreign body in the forehead, the retro-orbicularis fascia and preaponeurotic fat pad area were sutured, with the exception of the levator aponeurosis. This cyst-like mass was histopathologically proven to be a multiple pseudocyst. After excision, the swelling disappeared and the ptotic eyelid also improved. The galea is connected with the posterior orbicularis fascia. The galea and posterior orbicularis fascia layer can function as a pathway through which the injected material can migrate from the forehead to the upper eyelid. Weakening of the orbicularis retaining ligament and leakage of the foreign body through the supraorbital foramen may also cause filler migration. This case underscores the need for clinicians to be aware of the potential migration of filler even many years after an injection. We advise that filler injections should be performed by trained physicians and that it should be made known that migration is possible.

Sebaceous neoplasms are rare adnexal tumors that can present a challenge to clinicians. Only four cases of sebaceous carcinoma with sebaceoma have been reported in the literature. Herein, we describe the case of a sebaceous carcinoma originating from a sebaceoma in a solitary nodule of the posterior neck. Immunohistochemically, the tumor cells were strongly positive for epithelial membrane antigen and p53. It is possible that adnexal carcinomas may arise from malignant transformation of their benign counterparts as well as de novo. Malignant transformation was likely in this case because the lesion was composed of distinct benign and malignant components, and the benign component showed the typical histopathological features of sebaceoma. This case underscores the fact that partial and superficial biopsies sometimes may not provide the correct diagnosis. If a surgeon suspects malignancy based on a clinical examination, then it is mandatory to perform a deep biopsy.

Necrotizing fasciitis (NF) is defined as rapidly progressive necrosis of subcutaneous fat and fascia. Although NF of the face is rare, its mortality rate is nearly 30%. It usually originates from dental infection and can lead to involvement of the neck, mediastinum, and chest wall. Complications resulting from pre-existing systemic diseases can increase the mortality rate. Known complication factors for NF include diabetes, malnutrition, advanced age, peripheral vascular disease, renal failure, and obesity. Here, we report a case of NF originating from dental infection in an 88-year-old woman already diagnosed with hypertension, thoracic aortic aneurysm, and renal diseases. Such conditions limited adequate surgical and antibiotic treatment. However, interdisciplinary treatment involving multiple departments was implemented with good results.

OBJECTIVE: To examine the cardiorespiratory responses of patients with spinal cord injury (SCI) paraplegia using a motor driven rowing machine. METHOD: Ten SCI patients with paraplegia [A (n=6), B (n=1), and C (n=3) by the American Spinal Injury Association impairment scale] were selected. Two rowing techniques were used. The first used a fixed seat with rowing achieved using only upper extremity movement (fixed rowing). The second used an automatically moving seat, facilitating active upper extremity movement and passive lower extremity movement via the motorized seat (motor rowing). Each patient performed two randomly assigned rowing exercise stress tests 1-3 days apart. The work rate (WR), time, respiratory exchange ratio (R), oxygen consumption (VO2), heart rate (HR), metabolic equivalents (METs), and rating of perceived exertion (RPE) were recorded. RESULTS: WR, time, VO2, and METs were significantly higher after the motor rowing test than after fixed motor rowing test (p<0.05). HR after motor rowing was significantly lower than fixed rowing (p<0.05). CONCLUSION: Cardiorespiratory responses as VO2, HR and METs can be elicited by the motor rowing for people with paraplegic SCI.
