Background: Untreated dental caries or even dental manipulations, such as a tooth extraction, might cause direct spread of an odontogenic infection and consequently the development of life-threatening conditions such as deep neck infections (DNI). The most common source of DNI is of odontogenic origin (38.8–49%). Abscess formation or cellulitis can lead to life-threatening complications, despite new diagnostic imaging technology and widespread availability of antibiotics. 

Objectives: To demonstrate the dangers of DNI, which can create life-threatening situations.

Methods: Five cases of DNI of odontogenic origin, which were referred to the oral and maxillofacial surgery unit, are presented. 

Results: Clinical manifestations included trismus, dysphagia, dysphonia, dyspnea, and infection symptoms. In all cases, computed tomography confirmed diagnosis and extent of abscess. Complications included mediastinitis, respiratory distress, osteomyelitis of the jaws, and in rare cases the mandibular condyle. Treatment included securing the airway, immediate surgical drainage, removal of the infection source, and antibiotic therapy. All patients were discharged in stable and improved condition.

Conclusions: DNI treatment on an emergency basis requires proper diagnosis and effective management. To confirm diagnosis and prevent serious complications, it is essential for physicians to recognize the spaces of the head and neck that are likely to be affected by DNI. 

 

Background: The effect of repeated intravenous amantadine (IVAM) in advanced Parkinsonism has not been studied in depth.

Objectives: To report the experience of our medical center with repeated IVAM infusions in patients with advanced Parkinsonism.

Methods: Thirty patients with advanced Parkinsonism of various etiologies were enrolled in an open-label retrospective study. All patients were treated with IVAM infusions in a neurological daycare center. Treatment was initiated with a loading dose of 200/400 mg per day for 5 days followed by a once-daily maintenance dose of 200/400 mg every 1 to 3 weeks. Patients and their caregivers participated in a structured interview and independently completed a clinical global impression of changes scale questionnaire on various motor and non-motor symptoms.

Results: Patient mean age was 73.3 ± 9.7 years, average disease duration was 6.2 ± 5.7 years, and mean Hoehn and Yahr score was 3.2 ± 0.84. Mean duration of the IVAM treatment was 15.1 ± 11.6 months. An improvement in general function was reported by 91% of the patients and 89% of the caregivers. Most of the patients reported improvement in tremor and rigidity, as well as in gait stability, freezing of gait, and reduced falls. The treatment was safe with few side effects.

Conclusions: Our data suggest that repeated IVAM infusions could be an effective treatment against various motor symptoms and for improvement of mobility in patients with advanced Parkinsonism. Further randomized clinical trials with a larger sample size using objective measures are warranted to validate our results.

Background: Current guidelines for choosing between revascularization modalities may not be appropriate for young patients.

Objectives: To compare outcomes and guide treatment options for patients < 40 years of age, who underwent percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) between 2008 and 2018.

Methods: Outcomes were compared for 183 consecutive patients aged < 40 years who underwent PCI or CABG between 2008 and 2018, Outcomes were compared as time to first event and as cumulative events for non-fatal outcomes.

Results: Mean patient age was 36.3 years and 96% were male. Risk factors were similar for both groups. Drug eluting stents were implemented in 71% of PCI patients and total arterial revascularization in 74% of CABG patients. During a median follow-up of 6.5 years, 16 patients (8.6%) died. First cardiovascular events occurred in 35 (38.8%) of the PCI group vs. 29 (31.1%) of the CABG group (log rank P = 0.022), repeat events occurred in 96 vs. 51 (P < 0.01), respectively. After multivariate adjustment, CABG was associated with a significantly reduced risk for first adverse event (hazard ratio [HR] 0.305, P < 0.01) caused by a reduction in repeat revascularization. CABG was also associated with a reduction in overall repeat events (HR 0.293, P < 0.01). There was no difference in overall mortality between CABG and PCI.

Conclusions: Young patients with coronary disease treated by CABG showed a reduction in the risk for non-fatal cardiac events. Mortality was similar with CABG and PCI.

Giacomo Ceruti was a renowned painter in northern Italy during the middle third of the 18th century, although he is not well-known today. He produced pictures in several different genres but his reputation after his death was based primarily on his portrayal of beggars and poor working people; hence, his posthumous nickname, il Pitocchetto, the little beggar. Of medico-artistic interest is the realism with which he depicted the hands of his impoverished subjects, a quality that enables them to be examined for signs of pathology or trauma.

The present article displays some representative examples of hand deformities in Ceruti’s paintings, thus extending into the 18th century the authors' previous research on medical aspects of art works from the 15th to the 17th century.

Background: The policies and practices related to medical cannabis are currently in flux. These changes have been associated with many controversies, and there is a lack of consensus within the medical community regarding medical cannabis practices.

Objectives: To validate clinical vignettes that can be used to examine and improve medical cannabis practices.

Methods: Ten physicians participated in a Delphi survey of two consequent rounds in which they quantified the eligibility of medical cannabis therapy for six clinical vignettes describing both chronic pain and cancer patients.

Results: Higher consensus was achieved for the vignettes of cancer patients, which were additionally rated as more eligible for medical cannabis therapy. The highest level of consent (4.3 out of 5) was achieved regarding a vignette of a metastatic cancer patient. While in some cases physicians consolidated their ratings toward the group's average, in other cases they remained stable in their responses.

Conclusions: While controversies related to medical cannabis are expected to remain rampant, the validated vignettes may facilitate assessment of clinical practices, which is essential for a successful implementation of medical cannabis policies. These vignettes may additionally be used in medical training for appropriate patient selection for medical cannabis authorization.

Background: Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo. It is assumed that sleep is involved in the pathogenesis of BPPV, and that habitual head-lying side during sleep correlates with the affected side in the posterior semicircular canal BPPV.

Objectives: To investigate the relationship between the preferred sleeping position and the affected semicircular canal in patients with BPPV.

Methods: We performed a retrospective data review of patients seeking help for vertigo/dizziness who had undergone clinical evaluation including a Dix–Hallpike test. Patients diagnosed with posterior canal BPPV (p-BPPV) were asked to define their preferred lying side (right, left, supine, or variable) during the night sleep. Affected semicircular canal (right posterior or left posterior) was registered along with demographic data.

Results: In all, 237 patients were diagnosed with p-BPPV. Patients with horizontal semicircular canal BPPV (n=11) were excluded. Patient mean age was 57 years (range 14–87). There were 150 patients with right p-BPPV and 87 patients with left p-BPPV. Among the patients, 122 (52%) habitually slept on the right side. Of those, 102 (84%) were diagnosed with right p-BPPV (P = 0.0006), while 82 patients (34%) habitually slept on the left side. Fifty-three (65%) were diagnosed with left p-BPPV (P < 0.0001). There were no differences in right vs. left p-BPPV in the 33 patients (14%) who expressed no preference concerning their sleeping positions.

Conclusions: Our study highlights the etiology of BPPV and showed that changing sleep position habits might be helpful in preventing recurrent BPPV.

Background: Statins and selective serotonin reuptake inhibitors (SSRIs) have beneficial effects on health outcomes in the general population. Their effect on survival in debilitated nursing home residents is unknown.

Objectives: To assess the relationships between statins, SSRIs, and survival of nursing home residents.

Methods: Baseline patient characteristics, including chronic medications, were recorded. The association of 5-year survival with different variables was analyzed. A sub-group analysis of survival was performed according to baseline treatment with statins and/or SSRIs.

Results: The study comprised 993 residents from 6 nursing homes. Of them, 285 were males (29%), 750 (75%) were fully dependent, and 243 (25%) were mobile demented. Mean age was 85 ± 7.6 years (range 65–108). After 5 years follow-up, the mortality rate was 81%. Analysis by sub-groups showed longer survival among older adults treated with only statins (hazard ratio [HR] for death 0.68, 95% confidence intervals [95%CI] 0.49–0.94) or only SSRIs (HR 0.6, 95%CI 0.45–0.81), with the longest survival among those taking both statins and SSRIs (HR 0.41, 95%CI 0.25–0.67) and shortest among residents not taking statins or SSRIs (P < 0.001). The survival benefit remained significant after adjusting for age and after conducting a multivariate analysis adjusted for sex, functional status, body mass index, mini-mental state examination, feeding status, arrhythmia, diabetes mellitus, chronic kidney disease, and hemato-oncological diagnosis.

Conclusion: Treatment with statins and/or SSRIs at baseline was associated with longer survival in debilitated nursing home residents and should not be deprived from these patients, if medically indicated. 

Background: The need for postnatal monitoring of infants exposed to intrauterine beta blockers (BBs) has not been clearly defined.

Objectives: To evaluate infants exposed to intrauterine BBs in order to estimate the need for postnatal monitoring.

Methods: This retrospective case-control study comprised 153 term infants born to mothers who had been treated with BBs during pregnancy. Treatment indications included hypertension 76 mothers (49.7%), cardiac arrhythmias 48 (31.4%), rheumatic heart disease 14 (9.1%), cardiomyopathy 11 (7.2%) and migraine 4 (2.6%). The controls were infants of mothers with hypertension not exposed to BBs who were born at the same gestational age and born closest (before or after) to the matched infant in the study group.

Results: Compared to the control group, the infants in the study group had a higher prevalence of early asymptomatic hypoglycemia (study 30.7% vs. control 18.3%, P = 0.016), short symptomatic bradycardia events, other cardiac manifestations (P = 0.016), and longer hospitalization (P < 0.001). No life-threatening medical conditions were documented. The birth weight was significantly lower for the high-dose subgroup compared to the low-dose subgroup (P = 0.03), and the high-dose subgroup had a higher incidence of small-for-gestational-age (P = 0.02).

Conclusions: No alarming or life-threatening medical conditions were observed among term infants born to BB treated mothers. These infants can be safely observed for 48 hours after birth close to their mothers in the maternity ward. Glucose follow-up is needed, especially in the first hours of life.

Background: Anastomotic leakage (AL) is a major complication following colorectal surgery, with many risk factors established to date. The incidence of AL varies in the medical literature and is dependent on research inclusion criteria and diagnostic criteria.

Objectives: To determine the incidence of and the potential risk factors for AL following colorectal surgery at a single academic medical center.

Methods: We retrospectively reviewed all operative reports of colorectal procedures that included bowel resection and primary bowel anastomosis performed at Sheba Medical Center during 2012. AL was defined according to the 1991 United Kingdom Surgical Infection Study Group criteria. Data were assessed for leak incidence within 30 days. In addition, 17 possible risk factors for leakage were analyzed. A literature review was conducted.

Results: This cohort study comprised 260 patients, and included 261 procedures performed during the study period. The overall leak rate was 8.4%. In a univariate analysis, male sex (odds ratio [OR] 3.37, 95% confidence interval [95%CI] 1.21–9.43), pulmonary disease (OR 3.99, 95%CI 1.49–10.73), current or past smoking (OR 2.93, 95%CI 1.21–7.10), and American Society of Anesthesiologist score ≥ 3 (OR 3.08, 95%CI 1.16–8.13) were associated with an increased risk for anastomotic leakage. In a multivariate analysis, male gender (OR 3.62, 95%CI 1.27–10.33) and pulmonary disease (OR 4.37, 95%CI 1.58–12.10) were associated with a greater risk.

Conclusions: The incidence of AL in the present study is similar to that found in comparable series. Respiratory co-morbidity and male sex were found to be the most significant risk factors.

Background: Transesophageal endoscopic ultrasound-guided fine-needle aspiration using a bronchoscope (EUS-B-FNA) allows clinicians to determine mediastinal staging and lung mass evaluation of lesions not accessible by endobronchial ultrasound (EBUS) or where endobronchial ultrasound-guided transbronchial needle aspiration might not be safe.

Objectives: To evaluate the safety, diagnostic accuracy, and feasibility of EUS-B-FNA.

Methods: The study comprised patients who underwent a pulmonologist-performed EUS-B-FNA of mediastinal lymph nodes and parenchymal lung lesions between June 2015 and September 2017 at the Carmel Medical Center, Haifa, Israel.

Results: EUS-B-FNA was performed in 81 patients. The transesophageal procedure was performed for easier accessibility (49.4%) and in high-risk patients (43.3%). The most frequently sampled mediastinal stations were left paratracheal and sub-carinal lymph nodes or masses (38.3% and 56.7%, respectively). There were no complications (e.g., acute respiratory distress, esophageal perforation, or bleeding). An accurate diagnosis was determined in 91.3% of cases.

Conclusions: Pulmonologist-performed EUS-B-FNA is safe and accurate for evaluating mediastinal and parenchymal lung lesions and lymphadenopathy. Diagnostic accuracy is high. EUS-B-FNA may allow access to sites not amenable to other forms of bronchoscopic sampling, or may increase diagnostic accuracy in patients where anatomic position predicts a low diagnostic yield.

Background: The frequency of increased high-sensitivity C-reactive protein (hs-CRP) and the time course of evolution of their levels in patients with acute idiopathic pericarditis (AIP) are not well established.

Objective: To assess the time course of evolution of hs-CRP levels and the possible clinical significance of maximal hs-CRP levels in patients with AIP

Methods: We retrospectively reviewed the medical files of 241 patients admitted to the hospital with a diagnosis of AIP between March 2006 and March 2017. Data on demographics, time of symptom onset, laboratory and imaging findings, and outcome were collected.

Results: Data on serum hs-CRP levels were available for 225 patients (age 18–89 years, 181 men). Fever, pleural effusion, and age were independently associated with hs-CRP levels. Major cardiac complications (MCC) (death, cardiac tamponade, cardiogenic shock, large pericardial effusion, ventricular tachycardia, pericardiocentesis, or pericardiectomy) were more common in patients with hs-CRP levels above the median compared to those below (21.2% vs. 4.5%, respectively, P < 0.001). Hs-CRP levels were independently associated with MCC (odds ratio [OR] 1.071, 95% confidence interval [95%CI] 1.016–1.130, P = 0.011). Hs-CRP levels were elevated in 76.0%, 92.3% and 96.0% of the patients tested <6 hours, 7-12 hours, and >12 hours of symptom onset, respectively (P = 0.003). The frequency of elevated hs-CRP among patients tested > 24 hours was 98.1%.

Conclusions: Hs-CRP levels rise rapidly among patients with AIP. Maximal hs-CRP levels are associated with MCC. A normal hs-CRP level is rare among patients tested > 24 hours of symptom onset.

In non-ambulatory patients with cerebral palsy, the presence of scoliosis has a major impact on health and quality of life. The aim of this review is to raise awareness of caregivers from various professions to the extent of the problem, to explain the natural history of neuromuscular scoliosis and its pathophysiology, and to describe up-to-date optional conservative and surgical treatments.
