Health (Health) , 2013, DOI: 10.4236/health.2013.53057
Abstract:

Objectives: The purpose of this study was to investigate the methods of sheath removal (femostop, compressor and manual compression) among Jordanian patients post cardiac catherization. Material and Methods: A descriptive explorative design utilized to collect data from 87 patients underwent cardiac catherization. Data collected on demographics, health remarks and complication pre and post cardiac catherization and in relation to sheath removal methods and complications. Results: The majority of the patients (94.2%, n = 80) had a manual sheath removal compared to 1% (n = 1) compression and 7% (n = 6) had femostop method. Kruskal-Wallis H test revealed there were significance difference in PTT and ACT reports in relation to type of procedures (0.24, p 0.015; 0.32, p = 0.005 respectively). However, there were no significant differences between methods of sheath removal methods in relation to pain level, MAP before, MAP after, and heart rate with p value > 0.05. Patient’s age had negative association with HR after the procedure (BTAU = -0.19, p = 0.02), while no significant differences found in post catherization complication (hematoma and pain level) and all other health remarks (p > 0.05) in regards to patients’ age and gender. Moreover, patients’ MAP readings were significantly different in relation to number of rest hour that patients had post cardiac catherization (p = 0.049). Conclusion: The study found that most patients and health professionals preferred manual removal methods of sheath post cardiac catherization. Cardiac health professionals, has to consider health remarks and demographic characteristics of their patients when planning care for their patients and more research needed to explore these issues.

Abstract: This paper focuses on the case of intrabony mandibular schwannoma in a 39 yrs healthy male who was addressed by his dentist for an asymptomatic radiolucency of the left mandibular corpus. Computed Tomography Dentascan showed a soft tumour continuous to the path of the inferior alveolar nerve. Confirmation was made after surgical excision and careful histological examination. Radiolucent images of the mandible are frequently met by dentists and oro-facial surgeons, and suggest first odontogenic cysts because of their high frequency. But even if sheath nerve tumours are very rare, this case report reminds the necessity to keep them in mind.

Abstract: Rectus sheath hematoma (RSH) is a rare bleeding site which can be life-threatening. Our aim was to analyze clinical features, diagnosis, treatment and outcome of these cases in a general hospital. Results: During a period of 24 months, 8 cases of RSH were diagnosed (0.1% of all inpatients). Mean age was 79.4 years (y, SD +/- 14.1). 75% were female. 7 patients (pts) were on therapy with oral anticoagulants (OAC), 2 had a history of additional therapy with aspirin (ASA), 4 had low molecular weight heparin (LMWH) for bridging of OAC therapy. 4 pts had INR values between 3.1 - 4.4. One pt with liver cirrhosis (Child A), mild thrombocytopenia had ASA and LMWH prophylactically. Five pts (63%) were coughing. Main symptom was localized pain in 7 pts. One pt was incidentally diagnosed on a CT scan performed for different reason. 7 pts had a palpable mass of the abdominal wall. 5 RSH were diagnosed with CT, 2 with ultrasound, 1 clinically. All pts were treated conservatively. In 7 pts vitamine K and Beriplex® was substituted to reverse OAC. 4 pts received blood transfusions (1 - 4 units). The mean change of hemoglobin (Hb) was 37 g/l (SD +/- 22 g/l). The renal function was impaired in 7 pts (mean creatinine clearance 51 ml/min +/- 12.4) and declined further. 3 out of 8 pts died (38%, age 90 - 92 y, all female). In these patients, the observed change in Hb was 42 - 58 g/l. 2 pts had combination of VKA and LMWH. 1 pt had VKA only. Conclusion: Acute abdominal pain in pts with any form of OAC or therapy to inhibit platelet function should always raise suspicion about RSH. Extensive blood loss, shock and aggravation of

Abstract: Background: Hematoma in the rectus sheath is not common but if happens it will become major bleeding. Sometimes anticoaglation of deep vein thrombosis (DVT) causes the hematoma in the rectus sheath. Case Report: A 74-year-old female patient after total knee arthroplasty (TKA) due to osteoarthritis. Postoperation, residual DVT was noted in the right soleus vein on ultrasonography of the veins of the lower limbs. Anticoaglation was started 7.5 mg/day Arixtra for treatment of DVT. Anticoaglation was administered throughout rehabilitation, and abdominal pain developed on postoperative day 9. Since respiratory distress developed on day 10, then thoracoabdominal contrast CT was performed. Although no PE was observed, a hematoma was detected in the rectus sheath, and it perforated into the abdominal cavity. The hemoglobin level was reduced by about 4 g/dL, and the patient was admitted to the ICU. Surgical treatment was not performed, anticoagulant treatment was discontinued, and conservative treatment was administered. During management in the ICU, a total of 24 units of red blood cells were transfused. Conclusions: Rectus sheath hematoma should be in mind of surgeons during differential diagnosis of acute abdominal pain especially in patients receiving anticoagulants. Early recognition can be of great importance for patients’ recovery, preventing from severe complications. Management is usually supportive although surgical intervention in some patients should be considered.

Mushtaq Chalkoo, Shahnawaz Ahangar, Asim Rafiq Laharwal, Aasim Mushtaq Patloo, Abbass Mohd, Shabir Ahmed Dar
Surgical Science (SS) , 2011, DOI: 10.4236/ss.2011.23028
Abstract: Malignant peripheral nerve sheath tumor is a rare soft tissue sarcoma. Breast is an extremely rare location of this lesion and presentation as a breast lump in the absence of pain or previous benign neural tumor is even rarer. We report such a lesion in a 60 year-old female who presented with hard and painless breast lump for 2 years. Histopathology revealed a malignant spindle cell tumor of low grade potential. It was subsequently confirmed to be malignant peripheral nerve sheath tumor (MPNST) on the basis of immunopositivity for vimentin, neurone specific enolase and S-100.

Abstract: Plexiform schwannoma is a benign tumour arising from the sheath of myelinated nerve fibres that may occur in any part of the body. It is very rare in the head and neck region and poses diagnostic challenges. Here we present two unusual cases. The first is about a fifteen-year-old boy with a large plexiform schwannoma in the right retro maxillary region, extending up to but not invading the orbit. Initial cytology reported it as a pleomorphic adenoma, but histological findings after excision confirmed it to be a benign plexiform schwannoma. A zygomatic osteotomy was required to excise the tumour in its entirety. The second reported case is about solitary lesion on the tongue of a 46-year-old Chinese man, clinically mimicking a mucocoele. This case report highlights the diagnostic challenges posed by plexiform schwannoma, and the role of imaging and cytopathology, as well as the importance of definitive histopathological analysis. It also describes the surgical management of these lesions, and provides a review of the literature, in particular of cases occurring in the head and neck region.

International Journal of Otolaryngology and Head & Neck Surgery (IJOHNS) , 2015, DOI: 10.4236/ijohns.2015.44054
Abstract: Augmentation of nasal tip and/or dorsum forms the keystone of any Septorhinoplasty surgery. The grafts available for augmentation are numerous and varied. Choice of the graft depends upon the type of augmentation required, patient characteristics and, most importantly, the surgeon. In this article, we would like to present our experience with various augmentation grafts. In our experience, autografts are best grafts for augmentation. But in cases of revision surgeries or deficiency of autografts, allografts can be used. Our choice of allograft is Poly Diaxone Sheath or PDS.
