Diagnosis and treatment of an obsessive-compulsive disorder following traumatic brain injury: A single case and review of the literature

A 27-year-old patient with traumatic brain injury and neuropsychiatric symptoms fitting the obsessive-compulsive disorder was investigated. Brain CT-scan revealed left temporal and bilateral fronto-basal parenchymal contusions. Main Outcome Measure was the Yale-Brown Obsessive Compulsive Scale at pre- and post-treatment and at 6 months follow-up. The combination of pharmacotherapy and psychotherapy resulted in lower intensity and frequency of symptoms. Our case illustrates the importance of a detailed diagnostic procedure in order to provide appropriate therapeutic interventions. Further studies are needed to guide the clinician in determining which patients are likely to benefit from a psychotherapeutic intervention in combination with pharmacotherapy.

[Coumarin-induced necrotic purpura of the skin -- case report and review of the literature]

We report the case of a 28-year old woman with extensive red-black colored lesions of the skin on the left thigh, which appeared without trauma. The disease arrived during longterm coumarin therapy because of a deep vein thrombosis and an antiphospholipid syndrome. After consideration of the differential diagnoses and due to the typical clinical picture we made the diagnosis of coumarin necrosis. We review the clinical and therapeutic features for this rare complication.

Severe esophageal injuries occurring after general anesthesia in two cats: case report and literature review

Two healthy cats underwent elective surgical procedures under general anesthesia. One developed severe esophagitis leading to esophageal rupture, mediastinitis, and pyothorax. The other cat developed esophageal stricture, diverticulum formation, and suspected iatrogenic perforation. Both cats had signs of dysphagia and regurgitation beginning a few days after anesthesia. The first cat also had severe dyspnea due to septic pleural effusion and pneumomediastinum. In the second cat, endoscopy revealed diffuse esophagitis, an esophageal stricture, and a large esophageal diverticulum. Rupture of the esophageal wall occurred while inflating the esophagus for inspection. Due to the poor prognosis, both cats were euthanized. Necropsy revealed severe esophageal changes. Postanesthetic esophagitis has been previously described in dogs and cats; however, severe life-threatening esophageal injuries rarely occur as a sequel to general anesthesia. To the authors' knowledge, esophageal rupture secondary to perianesthetic reflux has never been reported in cats.

Mycobacterium microti infection in the cat: a case report, literature review and recent clinical experience

OVERVIEW: Mycobacterium microti infection is infrequently described in cats in the veterinary literature. It can be one of a large number of possible differential diagnoses in a feline patient with dermal nodules and non-healing draining ulcers, and can occasionally spread to involve the lungs and/or other areas of the body. CASE SUMMARY: This report describes the clinical signs, eventual diagnosis and variable response to treatment in a cat in Switzerland with recurrent cutaneous M microti infection. Only after several diagnostic and therapeutic attempts, over more than 2 years, was the species of Mycobacterium finally identified and targeted therapy given. PRACTICAL RELEVANCE: For any cat in which there is even a low suspicion of mycobacterial infection, the authors recommend that an aggressive diagnostic approach is taken. Tissue specimens should be collected and frozen early on, and, as soon as acid-fast bacilli are detected, samples should be sent to a mycobacterial reference laboratory for definitive identification. LITERATURE REVIEW: A review of the literature relating to the aetiopathogenesis, diagnosis and management of M microti infection in cats and dogs is included. This is supplemented with clinical and therapeutic experience gained from this case and other, unpublished cases managed over the past 15 years by one of the authors (DGM).

High-grade supraclavicular soft tissue sarcoma as secondary malignancy after successful treatment of acute myeloid leukemia: case report and literature review

It is well known that the treatment protocols for hematopoetic neoplasms carry a high risk of long-term oncogenicity. However, few reports have been published of sarcomas as secondary malignancies. An unusual case report of a soft tissue sarcoma appearing as a secondary cancer is presented, with a review of the published data. The present report involves a soft tissue sarcoma of the neck that occurred 18 years after curative treatment of acute myeloid leukemia by induction chemotherapy and bone marrow transplantation. Consecutive graft-versus-host disease affected the cervical skin. Soft tissue sarcomas appearing as secondary tumors are rare in oncology. The presented case describes the appearance of a sarcoma 18 years after curative treatment of acute myeloid leukemia. This is only the second case of this type reported in published studies.

Metastases and primary tumors around dental implants: A literature review and case report of peri-implant pulmonary metastasis

Ischemic muscle necrosis leading to life-threatening hyperkalemia. Case report and review of the literature

Objective: Description of a cat with ischemic muscle necrosis that suffered from cardiopulmonary arrest due to hyperkalemia. Pathogenesis, clinical signs and therapy of ischemic muscle necrosis are discussed and possible causes, symptoms and treatment of hyperkalemia are shown. Material and methods: case report of a four-year-old male castrated domestic shorthair cat. Results: The cat was successfully resuscitated and hyperkalemia was treated with different treatment modalities. Conclusion: Ischemic muscle necrosis can lead to severe live-threatening hyperkalemia which has to be anticipated, monitored and treated adequately. Aggressive fluid therapy might be responsible for a higher risk of hyperkalemia in predisposed cases. Clinical relevance: Potassium concentrations and acid-base disturbances must be closely monitored in patients with ischemic muscle necrosis

Biphosphonate-associated osteonecrosis of the maxilla. Case report and review of the literature

In recent years, a growing number of reports in the literature have linked osteonecrosis of the jaw bones with intravenously administered bisphosphonates prescribed for the treatment of hypercalcemia of malignancy due to bone lesions of multiple myeloma or bone metastases in patients with breast or prostate cancer. Furthermore, an association between chronic oral bisphosphonate use in patients with osteoporosis or Paget's disease, and bone necrosis in the mandible or maxilla has been demonstrated in numerous case reports and case series in the last couple of years. Therapeutically, osteonecrosis of the jaws seems to be difficult to treat surgically, often resulting in a recurring or even progressing lesion. In the present case report of a bisphosphonate-associated osteonecrosis of the maxilla in a patient with osteoporosis, the current literature will be discussed, and open research questions and potential problems for our daily dental practice routine will be addressed.

[Possible genetic link between Darier's disease and depression : Review of the literature and case history.]

Darier's disease is a rare, inherited autosomal dominant skin disorder caused by a mutation in the sarcoendoplasmatic reticulum calcium transporter (SERCA)-2-gene. In a number of pedigrees, Darier's disease closely relates with affective disorder. The most likely hypothesis for this is a susceptibility gene for affective disorder near the SERCA-2-gene. A 6.5-megabase region could be identified as a susceptibility locus. This region constitutes a susceptability locus also in affective disorder without Darier's disease. The underlying gene has not yet been identified.

[Intraoral lipoma in the region of the mental nerve--report of a case and review of the literature]

The intraoral lipoma is a benign, slowly growing, painless soft tissue neoplasia, which can cause esthetic or functional problems for the patient, depending on its size. All parts of the body can be affected, whereas the oral cavity is rarely involved. Clinically, the tumour often exhibits an exophytic growth pattern, a soft consistency, a broad base connected to the underlying tissue, and frequently has a reddish-yellowish colour. Instead of a superficial mucosal involvement, a deep localization in the soft tissues is also possible. Depending on the localization of the tumour, the diagnosis and the resulting therapy can turn out to be a challenge for the clinician. A clear differentiation to malign neoplasias of the fat tissues and other soft tissue expansions is essential. The following case report presents a female patient who is affected by a lipoma in the proximity of the mental nerve. The diagnostic work-up and resulting therapy including a review of the current literature are presented and discussed.

Rituximab for acute plasma-refractory thrombotic thrombocytopenic purpura. A case report and concise review of the literature

Thrombotic thrombocytopenic purpura (TTP) is a rare disease which responds well to plasma exchange treatment in the majority of patients. We report on a patient with acute TTP caused by severe autoantibody-mediated ADAMTS-13 deficiency, in whom remission was not achieved by initial treatment consisting of plasma exchange (PE), plasma infusion and corticosteroids, followed by vincristine and splenectomy. In view of the ongoing activity of TTP, treatment was initiated with rituximab, a chimaeric monoclonal antibody directed against the CD 20 antigen present on B lymphocytes. The patient received 4 weekly infusions of 375 mg/m2, each administered after the daily PE session and withholding PE until 48 hours later. Three weeks after the last infusion of rituximab a complete clinical and laboratory remission of this first episode of acute refractory TTP was documented. A concise review of the literature on the role of rituximab in patients with a first episode of acute plasma-refractory TTP suggests that rituximab in that situation may produce clinical remission in a significant proportion of patients, result in a lowered plasma requirement and avoid the complications of salvage immunosuppressive therapy. The use of rituximab in acute refractory TTP appears to be safe, with no excess infectious complications. We conclude that rituximab should be considered in TTP patients with acquired ADAMTS-13 deficiency who fail to respond clinically after 7-14 days of standard treatment with daily PE and glucocorticoids.

Multiple spinal extradural meningeal cysts presenting as acute paraplegia. Case report and review of the literature

Multiple spinal extradural meningeal cysts are rare. To the authors' knowledge, there have been only four reported cases in the world literature. The authors report a case of multiple spinal extradural meningeal cysts in a 31-year-old woman presenting with acute paraplegia. Magnetic resonance imaging of the thoracolumbar spine revealed multiple extradural cystic lesions extending from T-7 to T-8 and from T-12 to L-3. Intraoperative findings demonstrated a white, fibrous, and tense cyst filled with cerebrospinal fluid-like colorless fluid. Excision of the posterior wall of the symptomatic cyst was followed by immediate neurological improvement. The examination of the pathological specimen showed a thick duralike layer of collagen and an inner membrane of arachnoid that is often not found in these lesions. The final diagnosis was based on combined imaging, intraoperative, and histopathological findings. The authors review the literature and discuss the etiological, diagnostic, and therapeutic aspects of this lesion.

Therapy resistant neonatal seizures, linear vesicular rash, and unusually early neuroradiological changes: incontinentia pigmenti : A case report, literature review and insight into pathogenesis

CASE PRESENTATION: A substance abusing G2P1 mother spontaneously delivered at term an appropriate for gestational age girl. Neonatal seizures appeared at 21 hours and empiric anticonvulsive and antimicrobial treatment was started. At 25 hours, first vesicles appeared. While routine evaluations remained normal, a head CT revealed multifocal ischemic injuries, and a later MRI showed multifocal petechiae and diffusion abnormalities in the corticospinal tracts. The clinical diagnosis of incontinentia pigmenti (stage 1) was secured by histopathology. Follow-up at 13 months showed global developmental delay. DISCUSSION: We discuss the unusually early bilateral, fronto-occipital corticomedullar ischemias (CT day 3). On the MR imaging (day 7) extensive symmetric cerebral corticomedullar destruction and diffusion sequences with corticospinal tracts abnormalities are seen, which then evolve (day 26) to extensive symmetric cerebral destruction. We review the literature, genetics, suspected pathophysiology and possible neonatal manifestation. CONCLUSION: Incontinentia pigmenti is rare and, therefore, diagnosis is frequently delayed. Nevertheless, in the setting of therapy refractory seizures, excluded infections, and linear vesicular rash, a high index of suspicion is needed. This is the first report of simultaneous corticomedullar involvement as early as the third day of life.
