OBJECTIVE: To assess the utility of nasotracheal tubes in postoperative oxygen supplementation in dogs following corrective surgery for brachycephalic syndrome. DESIGN: Retrospective study 2003-2007. SETTING: University teaching hospital. ANIMALS: Thirty-six client-owned dogs that underwent corrective surgery for brachycephalic syndrome. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Medical records were reviewed for animals that underwent surgical interventions for brachycephalic syndrome including palatoplasty, ventriculectomy, and rhinoplasty. Data collected included signalment, presenting complaints, analgesic and surgical interventions, type of supplemental oxygen therapy, complications and mortality occurring during hospitalization. A nasotracheal tube (NTT) was placed in 20 dogs at the end of surgery; 16 dogs received other forms of oxygen supplementation (8) or no oxygen supplementation (8) during recovery. The total number of postoperative complications was similar in both groups (8/20 dogs with NTTs and 7/16 in those without NTTs). However, respiratory distress was observed in 5 dogs without NTTs but was not observed in any dog while an NTT was in place. One dog in each group died postoperatively. CONCLUSION: Placement of an NTT was found to be easy and may offer benefit in dogs with brachycephalic syndrome as a noninvasive means of delivering oxygen. The use of NTT may minimize severe postoperative morbidity, in particular by reducing postoperative respiratory distress.

The lower tuberculosis incidence reported in human immunodeficiency virus (HIV)-positive individuals receiving combined antiretroviral therapy (cART) is difficult to interpret causally. Furthermore, the role of unmasking immune reconstitution inflammatory syndrome (IRIS) is unclear. We aim to estimate the effect of cART on tuberculosis incidence in HIV-positive individuals in high-income countries.

In girls and adolescents with Turner syndrome (TS), is there a correlation between serum AMH levels and karyotype, spontaneous puberty and other biochemical markers of ovarian function, or growth hormone (GH) therapy? SUMMARY ANSWER: Serum anti-Müllerian hormone (AMH) correlates with karyotype, pubertal development, LH, FSH and are measurable in a higher percentage of TS patients under GH therapy. WHAT IS KNOWN ALREADY: Most girls with TS suffer from incomplete sexual development, premature ovarian failure and infertility due to abnormal ovarian folliculogenesis. Serum AMH levels reflect the ovarian reserve in females, even in childhood. STUDY DESIGN, SIZE, DURATION: Cross-sectional study investigating 270 karyotype proven TS patients aged 0-20 years between 2009 and 2010. PARTICIPANTS/MATERIALS, SETTINGS, METHODS: Studies were conducted at three University Children's hospitals in Europe. Main outcome measures were clinical data concerning pubertal development as well as laboratory data including karyotype, serum AMH, LH, FSH, estradiol (E2), inhibin B and IGF. RESULTS AND THE ROLE OF CHANCE: Serum AMH was detectable in 21.9% of all TS girls and correlated strongly with karyotypes. A measurable serum AMH was found in 77% of TS girls with karyotype 45,X/46,XX, in 25% with 'other' karyotypes and in only 10% of 45,X TS girls. A strong relationship was also observed for measurable serum AMH and signs of spontaneous puberty such as breast development [adjusted odds ratio (OR) 19.3; 95% CI 2.1-175.6; P = 0.009] and menarche (crude OR 47.6; 95% CI 4.8-472.9; P = 0.001). Serum AMH correlated negatively with FSH and LH, but did not correlate with E2 and inhibin B. GH therapy increased the odds of having measurable AMH in TS (adjusted OR 4.1; 95% CI 1.9-8.8; P < 0.001). LIMITATIONS, REASONS FOR CAUTION: The cross-sectional design of the study does not allow longitudinal interpretation of the data; for that further studies are needed. High percentage of non-measurable AMH levels in the cohort of TS require categorized analysis. WIDER IMPLICATIONS OF THE FINDINGS: Serum AMH levels are a useful marker of the follicle pool and thus ovarian function in pediatric patients with TS. These findings are in line with the published literature. The finding that GH therapy may affect AMH levels is novel, but must be confirmed by future longitudinal studies.

BACKGROUND: The recurrent ~600 kb 16p11.2 BP4-BP5 deletion is among the most frequent known genetic aetiologies of autism spectrum disorder (ASD) and related neurodevelopmental disorders. OBJECTIVE: To define the medical, neuropsychological, and behavioural phenotypes in carriers of this deletion. METHODS: We collected clinical data on 285 deletion carriers and performed detailed evaluations on 72 carriers and 68 intrafamilial non-carrier controls. RESULTS: When compared to intrafamilial controls, full scale intelligence quotient (FSIQ) is two standard deviations lower in carriers, and there is no difference between carriers referred for neurodevelopmental disorders and carriers identified through cascade family testing. Verbal IQ (mean 74) is lower than non-verbal IQ (mean 83) and a majority of carriers require speech therapy. Over 80% of individuals exhibit psychiatric disorders including ASD, which is present in 15% of the paediatric carriers. Increase in head circumference (HC) during infancy is similar to the HC and brain growth patterns observed in idiopathic ASD. Obesity, a major comorbidity present in 50% of the carriers by the age of 7 years, does not correlate with FSIQ or any behavioural trait. Seizures are present in 24% of carriers and occur independently of other symptoms. Malformations are infrequently found, confirming only a few of the previously reported associations. CONCLUSIONS: The 16p11.2 deletion impacts in a quantitative and independent manner FSIQ, behaviour and body mass index, possibly through direct influences on neural circuitry. Although non-specific, these features are clinically significant and reproducible. Lastly, this study demonstrates the necessity of studying large patient cohorts ascertained through multiple methods to characterise the clinical consequences of rare variants involved in common diseases.

A chronic pain syndrome, similar to the complex regional pain syndrome (CRPS) described in human beings, was diagnosed in a cow with persisting severe pelvic limb lameness. Diagnosis was based on the disproportionate relationship between the severity and duration of pain and the lesion, the failure of conventional analgesic and surgical therapy and the presence of characteristic clinical features. Multimodal therapy, i.e. a mixture of methadone, ketamine and bupivacaine was administered continuously for 17 days via an extradural catheter to counteract nociceptive hypersensitization. Doses were adjusted daily after assessing the effect, using a composite pain score. Physiotherapy was also performed. The diagnosis of CRPS in cattle is unusual. In this case, treatment was successful and the cow was discharged mildly lame and in improving physical condition. Long-term extradural analgesia proved to be safe and effective in the treatment of this syndrome, which was nonresponsive to conventional therapy.

Nasal polyposis is a very common and multifactorial disease. Whereas eosinophil-dominated polyps often are sensitive to anti-inflammatory treatment like corticosteroids, the therapy of polyps without eosinophils is more difficult and disappointing. We report the clinical course of a 29-year-old albino patient suffering from a extreme manifestation of Woakes' syndrome, which is characterized by severe recurrent nasal polyps, often without eosinophils on histological examination and with broadening of the nose. In this case, the recurrent fibrotic polyps without eosinophils were resistant to conventional medical and surgical treatment and required further treatment with radiotherapy with awareness of all possible future sequelae. The pathoetiology and treatment of Woakes' syndrome as well as of albinism were discussed.

The Hungry Bone Syndrome (HBS) represents an important cause of prolonged hypocalcemia after parathyreoidectomy (PTX) due to primary, secondary or tertiary hyperparathyreoidism. The sudden postoperative withdrawal of parathyroid hormone (PTH) induces a stop in osteoclastic bone resorption without affecting the osteoblastic activity. Consequently, an increased bone uptake of calcium, phosphate and magnesium is observed. Risk factors for the development of HBS include: Large parathyroid adenomas, age > 60 years, high preoperative levels of serum PTH, calcium and alkaline phosphatase. In these patients a careful monitoring of clinical symptoms of hypocalcemia as well as the laboratory parameters are warranted during the immediate postoperative period. Treatment with oral calcium, and especially in patients with renal failure, additionally active vitamin D should be started as soon as possible after PTX. In severe cases of HBS, the administration of intravenous calcium is necessary. The duration of therapy is governed by symptoms and severity of the HBS and may last for up to 12 or more months. While prevention of HBS in high risk patients includes preoperative Vitamin D, the role of bisphosphonates has yet to be established.

The acute compartment syndrome describes a posttraumatic or inflammatory edema, which leads to a painful constraint of muscular movement and paresthesia. An increase in pressure in the anatomical compartment is postulated. The main symptoms include local swelling, sensory loss, local muscle weakness as well as late livid discoloration. Therapy of choice is an early fasciotomy with decompression to avoid serious complications like muscle necrosis. Here we report a 22 year old patient who postoperatively suffered from a bilateral paresis of the foot jack. Further examinations by electromyography and magnetic resonance imaging (MRI) led to the diagnosis of an acute bilateral compartment syndrome.

A 59-year-old woman was examined because of weight gain, increasing fatigue and secondary amenorrhoea, which occurred after a complicated delivery at age 18. The finding of an increased TSH concentration was initially considered as primary hypothyroidism and substitution therapy was commenced. Because of the concomitant secondary amenorrhoea the patient was referred for additional endocrinological investigations.

AIMS: To determine the effect of anti-ischaemic drug therapy on long-term outcomes of asymptomatic patients without coronary artery disease (CAD) history but silent exercise ST-depression. METHODS AND RESULTS: In a randomized multicentre trial, 263 of 522 asymptomatic subjects without CAD but at least one CAD risk factor in whom silent ischaemia by exercise ECG was confirmed by stress imaging were asked to participate. The 54 (21%) consenting patients were randomized to anti-anginal drug therapy in addition to risk factor control (MED, n = 26) or risk factor control-only (RFC, n = 28). They were followed yearly for 11.2 +/- 2.2 years. During 483 patient-years, cardiac death, non-fatal myocardial infarction, or acute coronary syndrome requiring hospitalization or revascularization occurred in 3 (12%) of MED vs. 17 (61%) of RFC patients (P < 0.001). In addition, MED patients had consistently lower rates of exercise-induced ischaemia during follow-up, and left ventricular ejection fraction remained unchanged (-0.7%, P = 0.597) in contrast to RFC patients in whom it decreased over time (-6.0%, P = 0.006). CONCLUSION: Anti-ischaemic drug therapy and aspirin seem to reduce cardiac events in subjects with asymptomatic ischaemia type I. In such patients, exercise-induced ST-segment depression should be verified by stress imaging; if silent ischaemia is documented, anti-ischaemic drug therapy and aspirin should be considered.

Ischemic colitis results from insufficient blood supply to the large intestine and is often associated with hypercoagulable states. The condition comprises a wide range presenting with mild to fulminant forms. Diagnosis remains difficult because these patients may present with non-specific abdominal symptoms. We report a 51- year-old female patient with known Leiden factor V mutation as well as systemic lupus erythematous along with antiphospholipid syndrome suffering from recurrent ischemic colitis. At admission, the patient complained about abdominal pain, diarrhea and rectal bleeding lasting for 24 hours. Laboratory tests showed an increased C-reactive protein (29.5 mg/dl), while the performed abdominal CT-scan revealed only a dilatation of the descending colon along with a thickening of the bowel wall. Laparotomy was performed showing an ischemic colon and massive peritonitis. Histological examination proved the suspected ischemic colitis. Consecutively, an anti-coagulation therapy with coumarin and aspirin 100 was initiated. Up to the time point of a follow up examination no further ischemic events had occurred. This case illustrates well the non-specific clinical presentation of ischemic colitis. A high index of suspicion, recognition of risk factors and a history of non-specific abdominal symptoms should alert the clinicians to the possibility of ischemic disease. Early diagnosis and initiation of anticoagulation therapy or surgical intervention in case of peritonitis are the major goals of therapy.

Even though depressions and depressive symptoms are frequently observed in patients with medical diseases, their psychological problems are often neither diagnosed nor treated. Diagnosis of mood state might be easy in isolated cases yet it often is not since the precise nature of normal mood cannot be expressed in quantitative terms. Furthermore, depression can only be diagnosed based on the doctor's clinical appraisal and the patient's own description of his/her complaints. There is no gold standard on which depressive symptoms can be based on--and further on, depression is not a diagnosis. Instead, it is a syndrome that calls for differential diagnoses before treatment can be offered. Diagnosing depressive comorbidity in patients with medical complaints is even more difficult because of the overlap between symptoms of depression and accompanying symptoms of the somatic illness e.g. lack of energy. Although depressive states have been known to be a risk factor for the prognosis of patients with coronary heart disease for a long time, there is a paucity of research about the therapy these patients undergo due to the fact that tricyclic anti-depressants can have cardiotoxic effects on patients with heart disease. The treatment of depression in these patients has become a much lower risk since the introduction of serotonin reuptake inhibitors. There is widespread evidence that depressive comorbidity has a negative impact on the prognosis of medical disorders. Despite the complex nature of diagnosing depression, proper diagnosis and treatment is increasingly important in internal medicine and especially cardiology.

Although Henoch-Schönlein syndrome can occur at any age, it is overwhelmingly a disease of childhood. Indeed, Henoch-Schönlein syndrome is the most common vasculitis that affects children. The clinical features of this vasculitis are well documented, and the diagnosis is generally not difficult. This article briefly reviews both common and uncommon clinical aspects of the condition and information concerning therapy. A further focus of this review is recent information concerning abnormalities of immunoglobulin IgA1 glycosylation and the role of aberrantly glycosylated immunoglobulins in the development of Henoch-Schönlein syndrome. The final focus of the article is acute hemorrhagic edema, a benign vasculitis limited to the skin, which is characterized by circinate, medallion-like purpura, and ecchymoses and occurs in children younger than 4 years of age. The nosologic position of acute hemorrhagic edema, which has also been called Finkelstein-Seidlmayer syndrome, as a variant of Henoch-Schönlein syndrome is the subject of considerable debate, but most authors agree that there are sufficient clinical and prognostic differences to consider it a separate entity.

OBJECTIVE: To simultaneously determine perceived vs. practiced adherence to recommended interventions for the treatment of severe sepsis or septic shock. DESIGN: One-day cross-sectional survey. SETTING: Representative sample of German intensive care units stratified by hospital size. PATIENTS: Adult patients with severe sepsis or septic shock. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Practice recommendations were selected by German Sepsis Competence Network (SepNet) investigators. External intensivists visited intensive care units randomly chosen and asked the responsible intensive care unit director how often these recommendations were used. Responses "always" and "frequently" were combined to depict perceived adherence. Thereafter patient files were audited. Three hundred sixty-six patients on 214 intensive care units fulfilled the criteria and received full support. One hundred fifty-two patients had acute lung injury or acute respiratory distress syndrome. Low-tidal volume ventilation < or = 6 mL/kg/predicted body weight was documented in 2.6% of these patients. A total of 17.1% patients had tidal volume between 6 and 8 mL/kg predicted body weight and 80.3% > 8 mL/kg predicted body weight. Mean tidal volume was 10.0 +/- 2.4 mL/kg predicted body weight. Perceived adherence to low-tidal volume ventilation was 79.9%. Euglycemia (4.4-6.1 mmol/L) was documented in 6.2% of 355 patients. A total of 33.8% of patients had blood glucose levels < or = 8.3 mmol/L and 66.2% were hyperglycemic (blood glucose > 8.3 mmol/L). Among 207 patients receiving insulin therapy, 1.9% were euglycemic, 20.8% had blood glucose levels < or = 8.3 mmol/L, and 1.0% were hypoglycemic. Overall, mean maximal glucose level was 10.0 +/- 3.6 mmol/L. Perceived adherence to strict glycemic control was 65.9%. Although perceived adherence to recommendations was higher in academic and larger hospitals, actual practice was not significantly influenced by hospital size or university affiliation. CONCLUSIONS: This representative survey shows that current therapy of severe sepsis in German intensive care units complies poorly with practice recommendations. Intensive care unit directors perceive adherence to be higher than it actually is. Implementation strategies involving all intensive care unit staff are needed to overcome this gap between current evidence-based knowledge, practice, and perception.
