INTRODUCTION: Interdigital pilonidal sinus is an acquired condition secondary to penetration of hair fragments into the skin of the web spaces of the hands commonly observed in hairdressers, and occasionally, among pet groomers. Local literature reports or guidelines to ensure practice of protective measures for this population of workers are currently lacking. CASE SUMMARY: A 24-year old pet groomer consulted due to occasional white hair strands emerging from two openings in the third interdigital space of his dominant hand. Histopathologic examination of the sinus tract showed an acanthotic, hyperplastic epidermis with scale crust, and nodular dermal infiltrates composed of epithelioid histiocytes, plasma cells, lymphocytes, and eosinophils. Transepidermal extrusion of polarizable hair cortical material was also evident establishing the diagnosis of an interdigital pilonidal sinus. Sinusectomy and debridement with healing by secondary intention resulted in an optimal wound closure and full motion of the affected hand after one week and minimal scarring with no recurrence after seven months. CONCLUSION Surgical excision followed by proper wound care is essential to avoid recurrence. In conclusion, since interdigital pilonidal disease is a rare condition, awareness among physicians would lead to accurate diagnosis, optimal treatment, and proper patient education.

This study examined the behavioral change and memory impairment following transient forebrain ischemia in 20 male rats: ten rats were subjected to sham operation. Inchemia was induced by a combination of bilateral common carotid artery occlusion and induced hypotension. During the recovery period, behavioral change was evaluated by open-field method. Histopathological examination was performed 7 days after ischemic insult. The results were as follows 1) Hippocampus CA 1 neuron was the most vulnerable to 10-minute forebrain ischemia. 2) There was increase in locomotor activity and rearing during early post-ischemic period. 3) Ischemia resulted in suppressed preening and grooming. From the above mentioned results, authors suggested that transient forebrain ischemia produced severe neuronal damage in CA l sector of hippocampus, therefore produced behavioral change and memory impairment.

OBJECTIVE: This study was aimed to investigate the effectiveness of cognitive training to Instrumental Activities of Daily Living (IADL) in community-dwelling elderly. METHODS: The participant were 786 elders who were aged over 59 years visiting local rest area from February 2015 to November 2015. The demographic data was collected. IADL were evaluated by Seoul-Instrumental Activities of Daily Living (S-IADL). Cognitive functions were evaluated by Korean Version of Mini Mental Status Examination for Dementia Screening (MMSE-DS). Before and after cognitive training, we analysed these data. RESULTS: In all 15 items of S-IADL, 4 items (using the telephone, grooming, managing belongings, talking recent events) were specially improved (p<0.05). CONCLUSION: After cognitive training, indoor activities of S-IADL were improved but some items, especially outside activities were not improved for community dwelling elderly. In future, other programs to increase outside activities or social activities should be included in cognitive training programs for community dwelling elderly.

BACKGROUND: The aim of this study was to investigate the development of neuropathic pain by radiofrequency thermocoagulation on a rat infraorbital nerve (IoN). METHODS: Male Sprague-Dawley rats (n = 35) were divided into three groups, consisting of the S, T and sham operation. In the experimental groups, rats were thermocoagulated by subjecting them to 70oC for 60 sec (S group, n = 12) or 20 sec (T group, n = 11) on IoN. In the control group (sham operation, n = 12), IoN was not thermocoagulated. The ipsilateral grooming count and escape threshold by von Frey filament (mechanical allodynia) was measured at 1, 3, 5, 7, 9, 11, 13 postoperative days. After two weeks, a 5% formalin solution was injected into the rat upper lips and grooming time was measured for 45 minutes. RESULTS: Grooming count and mechanical allodynia significantly increased in the thermocoalgulation groups (S and T groups) compared to control group (sham operation) for the postoperative days. Nerve injury by radiofrequency thermocoagulation enhanced the grooming time after formalin injection in the rat upper lips. CONCLUSIONS: These results lend support to the hypothesis that thermal injury using radiofrequency thermocoagulation can induce neuropathic pain in rat IoN and this type of nerve injury increases the responsiveness of chemical nocieptive stimuli.

Hair has a significant physical, psychological and social impact on an individual's daily life and well being. Understanding the basic structure and the factors that affect hair fiber integrity leads to better handling and care of our hair.
Hair is a slowly renewable protein fiber which grows at a rate of about 1 cm per month. Once hair emerges from the scalp, it is a non living matter.' From the scalp exit point to the distal portion of the hair strand, any injury to the hair structure is irreversible. Subjecting the hair fiber to the least amount of dailytrauma helps to minimize any damage to the hair fiber.
Hair fiber is mainly keratin protein and a small amount of lipid and other components. It is made up of an inner cortex, medulla and an external cuticle layer. The hair cuticle is made up of overlapping cell layers (approximately 5-10 layers) which covers the entirehair fiber. Each cuticular cell has inner layers (A layer and the endocuticle), outer sublamellar structures and an outer membrane, containing lipids mainly 18-methyl eicosanoic acid which imparts a hydrophobic nature to the cuticle.' The condition of the cuticle mainly determines the cosmetic appearance of the hair and being the most external layer, is the part of the hair most vulnerable to the effects of daily grooming, cosmetic treatments and the environment.
The cortex has a winded helical configuration of long microfibers linked to each other to form larger structures which gives the hair its tensile strength and elasticity." The inner location of the cortex makes it less prone to damage thus injury to the cortex signifies more severe damage to the outer cuticles allowing extension to the inner cortex. The medulla is the innermost cylindrical part of the hair fiber whose function is not as clear as the other two structures.

BACKGROUND: The growing number of spinal cord injured individuals facing old age makes the understanding of age related limitations increasingly important. This study was to investigate the age-related differences in rehabilitation outcome according to the level of cervical spinal cord injury and each category of activity of daily living(ADL). METHODS: Subjects were 79 adults with tetraplegia all of whom were admitted in National Rehabilitation Hospital. The level of injury was classified into upper cervical(C4, C5), mid-cervical(C6), and lower cervical(C7, C8) spinal cord injury. Eight ADL categories including feeding, grooming, bathing, dressing, toileting, bed-transfer, toilet/tub transfer, and indoor mobility were assessed using the scale of Spinal Cord Independence Measure. Age related differences were examined by separating the sample into two age groups(> or =40 and <40 years) RESULTS: There was no age related difference in rehabilitation outcome in upper cervical cord injury patients. In mid-cervical cord injury level, ADL capacities differed only in the feeding and grooming activities. In lower cervical cord injury level, older patients showed lower rehabilitation outcome than younger counterparts in all ADL categories examined. CONCLUSION: Along with injury level, age should be considered when formulating rehabilitation plans and functional prognostic statements in tetraplegic patients.

PURPOSE: This study was conducted to compare the recovery state of 6 month between s-ICH and s-SAH patients. The patients' recovery state was measured with 2 dimensions: functional and cognitive. METHODS: Non-experimental prospective design was adopted by including 108 hemorrhagic stroke patients(s-ICH: 52 vs s-SAH: 56) admitted to Intensive Care Unit of one university hospital. RESULTS: The study results showed that overall functional recovery state of s-SAH patients was better than that of s-ICH patients, and s-SAH patients also showed better recovery states in all of the sub-dimensions of functional recovery, such as feeding, grooming, and toileting, than those of s-ICH in 6 month. On the contrary, the study results showed that overall cognitive recovery states of 6 month between two groups were not significantly different. However, according to the results comparing the sub-dimensions of cognitive recovery, s-SAH patients' recovery states on attention, communication and memory were significantly better than those of s-ICH patients, while recovery states on problem solving, safety behavior, and social behavior between 2 groups were not significantly different. CONCLUSION: From the study results, it was noted that s-SAH patients showed better recovery states in cognitive dimension as well as in functional dimension compared with s-ICH patients.

BACKGROUND: This study was conducted to examine the effects of ad libitum consumption of highly palatable food (HPF) during adolescence on the adverse behavioral outcome of neonatal maternal separation. METHODS: Male Sprague-Dawley pups were separated from dam for 3 hours daily during the first 2 weeks of birth (maternal separation, MS) or left undisturbed (nonhandled, NH). Half of MS pups received free access to chocolate cookies in addition to ad libitum chow from postnatal day 28 (MS+HPF). Pups were subjected to behavioral tests during young adulthood. The plasma corticosterone response to stress challenge was analyzed by radioimmunoassay. RESULTS: Daily caloric intake and body weight gain did not differ among the experimental groups. Ambulatory activities were decreased defecation activity and rostral grooming were increased in MS controls (fed with chow only) compared with NH rats. MS controls spent less time in open arms, and more time in closed arms during the elevated plus maze test, than NH rats. Immobility duration during the forced swim test was increased in MS controls compared with NH rats. Cookie access normalized the behavioral scores of ambulatory and defecation activities and grooming, but not the scores during the elevated plus maze and swim tests in MS rats. Stress-induced corticosterone increase was blunted in MS rats fed with chow only, and cookie access normalized it. CONCLUSION: Prolonged access to HPF during adolescence and youth partly improves anxiety-related, but not depressive, symptoms in rats that experienced neonatal maternal separation, possibly in relation with improved function of the hypothalamic-pituitary-adrenal (HPA) axis.

BACKGROUND: The pathophysiological and neurochemical changes following spinal injury are not yet elucidated. This study was designed to evaluate the morphological changes of the dorsal horn of the spinal cord and profiles of pain behaviors following intraspinal injection of NMDA in rats. METHODS: Rats were randomized into three groups: a sham-operated control group and groups where the rats received 10 mM or 100 mM N-methyl-D-aspatate (NMDA) injected into their spinal dorsal horn. Following injection, hypersensitivity to cold and mechanical stimuli and excessive grooming behaviors were assessed serially for four weeks. Morphological changes of the spinal cord were evaluated four weeks after intraspinal injection. RESULTS: Few animals in the NMDA groups developed hypersensitivity to cold and mechanical stimuli. The number of groomers and the severity of excessive grooming were significantly higher in the 100 mM NMDA group than those values of the control and 10 mM NMDA groups. The size of the neck region (lamina III-IV) was significantly smaller in the 100 mM NMDA group than in the control and 10 mM NMDA groups. CONCLUSIONS: In conclusion, intraspinal injection of NMDA in rats leads to the pathological sequela in the spinal cord and to excessive grooming behavior. These results support the use of NMDA and excessive grooming behavior after excitotoxic SCI as a model to study chronic pain after SCI.

BACKGROUND: Gabapentin is a novel anti-epileptic drug, which is used in clinical practice to treat epilepsy. This drug is also used as an analgesic in pain patients. The antinociceptive effect of this drug was assessed using the formalin test in the rat. METHODS: In order to investigate the effects of gabapentin on the trigeminal nerve territory, we injected 0.5 % formalin into the upper lip. Adult, male, Sprague-Dawley rats received a 50mul subcutaneous injection of 5% formalin into one vibrissal pad and the consequent, facial grooming behavior was monitored. Consistent with previous investigations using the formalin model, animals exhibited biphasic nocifensive grooming (phase 1, 0-12 min; phase 2, 12-60 min). RESULTS: The intraperitoneal administration gabapentin 5 minutes prior to the formalin injection led to a significant, dose-dependent reduction in grooming time during phase 2. In high doses, gabapentin also reduced the time of grooming during phase 1. CONCLUSIONS: The Intraperitoneal injection of gabapentin has an analgesic effect in the facial formalin rat model and this analgesic effect increases dose-dependently.
