As wireless and mobile technologies have advanced significantly, lots of large sized healthcare organizations have implemented so called mobile hospital (m-Hospital) which provides a location independent and point of care (POC) clinical environment. Implementation of m-Hospital enhances quality of care because health professionals such as physicians and nurses can use hospital information systems at the very place where patients are located without any delay. This paper presents a real-time patient monitoring system based on wireless network technologies. A general framework for the patient monitoring process is introduced and the architecture and components of the proposed monitoring system is described. The system collects and analyzes biometric signals of in-patients who suffer from cancer. Specifically, it continuously monitors oxygen saturation of patients in bed and alarms health professionals instantly when an abnormal status of the patient is detected. The monitoring system has been used and clinically verified in a university hospital.

The calcaneal insufficiency avulsion fracture usually occurs in an area of fused apophysis in adults without significant history of trauma or overuse activities. It is an uncommon injury which has been described in patients with complicated diabetes, Charcot neuroarthropathy, amyloidosis with neuropathy, severe osteoporosis, and other conditions. Discussion of the issue of fracture location is still not sufficient. We report on a case of a 50-year-old male who experienced a non-traumatic diabetic calcaneal insufficiency fracture. Intraoperatively, a biopsy specimen was obtained from the exposed fracture site for histological study. We assume that the calcaneal fused apophyseal line is the weak point of failure due to various incomplete mixtures of trabecular bone, woven bone, and cartilaginous tissues, and may fail when repeated tensile stress is imposed.

Fractures of C1 are not uncommon, constituting only 10% of all cervical spine injuries. There is a high prevalence of concomitant fractures of the second and first cervical vertebral complex. Surgical treatment is controversal. Mainstay of treatment is various combination of traction and cervical orthosis according to degree of displacement and location of fracture. We experienced unusual type of fracture, anterior arch fracture of C1 who had a history of total laminectomy of C1,2 due to cervical cord tumor(neurilemmoma arising from C2 root). We performed C1,2 lateral mass screw fixation with posterior fusion with good postoperative outcome.

Most of physical therapists has thought be exposed themselves to risk of hospital infection but it is reported that have been low concern about infection management. Above like this haven t done systematical education on hospital infection, also physical therapist's information management of infection disease is found very low. It is lack of driving information about disease condition of the patients. Physical therapists has thought their working room may be polluted a lots of micro-organism(%). The control situation of infection waste articles, only 53% responded that the controller has managed very intensive so we can feel to need more intensive It's reported that air culture investigation of physical therapy room has never initiated. To wash the hand, before, after treatment of the patients of physical therapist, is very low frequency. And 73% have responded that the time to wash the hand stays 15-45 second. It is examined that 70% physical therapy room is equipped with washing system, a response of 58% disinfects physical therapy room 1-2times per one month. 36% responded disinfection of treatment modality have done everyday, 25% responded have never done. The location physical therapy room is above one floor - 65%. A response of 57% is ventilation system sufficiency, it is considered that physical therapists needs more efforts on management of hospital infection.

Complete colonic duplication is a very rare congenital anomaly that may have different presentations according to its location and size. Complete colonic duplication can occur in about 15% of all gastrointestinal duplications. Double termination of tubular colonic duplication in the perineum is even more uncommon. We present a case of a Y-shaped tubular colonic duplication which presented with a rectovestibular fistula and a normal anus. Radiological evaluation and initial exploration for sigmoidostomy revealed duplicated colons with a common vascular supply. Endorectal mucosal resection of theduplicated distal segment till the colostomy site with division of the septum of the proximal segment and colostomy closure proved curative without compromise of the continence mechanism. Tubular colonic duplication should always be ruled out when a diagnosis of perineal canal is considered in cases of vestibular fistula alongwith a normal anus.

Background: The aim of this study was to analyze the clinicopathological and immunohistochemical features of primary central nervous system lymphoma (PCNSL) cases occurring in Indian patients and also study the utility of the crush smear preparation in intraoperative diagnosis. Materials and Methods: The immune status, clinical, radiological details, immunohistochemical profile, histopathological findings and cytological features in smear preparation of 32 cases of PCNSL were analyzed. Patients with systemic NHL and skull-base lymphomas were excluded. Results: The mean age of our patients was 52 years with a male: female ratio 1:1. A periventricular location was found in 62.5% of patients. None of our PCNSL cases were associated with AIDS. All cases except one were diffuse large B-cell lymphomas. Intraoperative diagnosis using crush smears allowed correct prediction in 93% of cases. Conclusions: Our study shows that PCNSL is seen predominantly in immunocompetent patients in India. The age of presentation is relatively young as compared to the West. Our study also stresses the utility of crush smear preparation in establishing an intraoperative diagnosis.

Athke's cleft cysts are believed to be derived from remnants of Rathke's pouch, a dorsal invagination of the stomodeum. Although these cysts are characteristically small, asymptomatic and intrasellar in location, they occasionally provoke symtoms with enlargement to compress surrounding structures. It is characteristically lined by stratified squamous epithelium with keratinization on a layer of connective tissue. The cells of the anterior pituitary lobe, from which pituitary adenomas develop, are also formed by the proliferation of the anterior wall of Rathke's pouch. Thus, Rathke's cleft cyst and pituitary adenomas are considered to have a common ancestry. We report a rare case in which the preoperative diagnosis was pituitary adenoma, but the pathologic diagnosis was a combination of a Rathke's cleft cyst and a coincidental pituitary adenoma.

Objective : Chronic subdural hematomas (CSDH) are more common on the left hemisphere than on the right. We verified this left predilection of CSDH and tried to explain the reason for this discrepancy. Methods : We investigated the laterality of CSDH in 182 patients who were treated from January 2005 to December 2009. We examined the symmetry of the cranium and the location of the lesion. Results : CSDH was more common on the left-side. The cranium was symmetric in 63 patients, asymmetric in 119 patients. The asymmetric crania were flat on the right-side in 77 patients, on the left-side in 42 patients. The density of the CSDHs was hypodense in 29 patients, isodense 132 patients, and the others in 21 patients. Bilateral hematomas were more common in the hypodense group. In the right flat crania, the hematoma was more commonly located on the opposite side of the flat side. While in the left flat crania, the hematoma was more common on the same side. Conclusion : CSDHs occurred more frequently on the left side. The anatomical asymmetry of the cranium influences the left predilection of CSDH.

Leiomyoma is a benign smooth muscle tumor that usually arise in the uterus, skin and gastrointestinal system. Only 2 percent are located in the head and neck. Leiomyomas of oral cavity are uncommon as only two cases have been reported in the Korean literature. The common location of oral cavity has been tongue, but other sites include buccal mucosa, lips, palate. mouth floor, and gingiva. Our patient was 30 years old female who complained of swelling and discomfort in the mouth floor. Microscopically this tumor showed bundles of intertwining spindle cells within fibrous connective tissue stroma. The nuclei were generally pale staining and blunt ended. Masson's trichrome stain was positive for muscle, and immunohistochemical study for ${\alpha}$-smooth muscle actin revealed strong positivity. It was treated by surgical excision. We experienced a case of leiomyoma of oral cavity, so we report with literature reviews
