Zika virus (ZIKV) was identified in 1947 in a rhesus monkey during an investigation of the yellow fever virus in the Zika Forest of Uganda; it was also isolated later from humans in Nigeria. The main distribution areas of ZIKV were the African mainland and South-East Asia in the 1980s, Micronesia in 2007, and more recently the Americas in 2014. ZIKV belongs to the Flaviviridae family and Flavivirus genus. ZIKV infection, which is transmitted by Aedes mosquitoes, is an emerging arbovirus disease. The clinical symptoms of ZIKV infection are fever, headache, rashes, arthralgia, and conjunctivitis, which clinically resemble dengue fever syndrome. Sometimes, ZIKV infection has been associated with Guillain-Barré syndrome and microcephaly. At the end of 2015, following an increase in cases of ZIKV infection associated with Guillain-Barré syndrome and microcephaly in newborns in Brazil, the World Health Organization declared a global emergency. Therefore, considering the global distribution and pathogenic nature of this virus, the current study aimed at reviewing the virologic features, transmission patterns, clinical manifestations, diagnosis, treatment, and prevention of ZIKV infection.

This study aims to define and compare sensory phenotypes in cervical radiculopathy patients exhibiting neuropathic pain (NP) components with healthy volunteers using clinical examination and quantitative sensory test (QST) findings. Another aim of the study is to show whether symptomatic components of the pain detect questionnaire (PDQ) are correlated with the QST findings, which may help clinicians indicate patients with sensory abnormalities without the use of specialized tests.

The optimal analgesia for video-assisted thoracoscopic surgery (VATS) is still unknown.

Background and objective Accidental dural puncture (ADP) and consequent post-dural puncture headache (PDPH) related to epidural needle use have prompted the design of a pencil-point epidural needle. The aim of this prospective, randomized, single-blind pilot study was to assess the efficacy, ease of use, patient satisfaction, and adverse events associated with this newly designed pencil-point epidural needle compared to a Tuohy conventional epidural needle in parturients receiving combined spinal-epidural (CSE) anesthesia for labor. Methods After obtaining the Institutional Research Board approval, 100 parturients were randomized to receive CSE anesthesia with either the new pencil-point epidural needle (Gertie Marx, IMD Inc., Huntsville, UT) (P group) or Tuohy needle (T group). We documented patients' height, weight, loss of resistance (LOR), number of attempts required, onset time of spinal anesthesia, difficulties with insertion of spinal needle, difficulties with insertion of the epidural needle and catheter, duration of the procedure, overall satisfaction of the provider and patient, ADP, PDPH, paresthesia, and pain. Results There was no difference in body mass index (BMI), LOR, number of attempts, and onset time of spinal anesthetic between the study groups. Success in obtaining cerebrospinal fluid (CSF) on the first attempt was 50/51 (98%) in the T group vs. 44/49 (89.8%) in the P group (p=0.108). The need for subsequent epidural needle readjustment to obtain CSF was higher in the P group (16/49, 32.7%) vs. the T group (3/51, 5.9%, p<0.001). Success on the first attempt with epidural catheter threading was lower with the pencil-point epidural needle compared to the Tuohy needle (69% vs. 98%, p<0.001). The anesthesiologist switched from the assigned pencil-point epidural needle to the Tuohy needle due to technical difficulties in 8/49 (16.3%) cases. The duration of the procedure was longer in the P group (16.43 ±6.33 minutes) compared to the T group (11.49 ±1.87 minutes) (p<0.001). User satisfaction was lower in the P group compared to the T group (34.7% vs. 90.2%, p<0.001). Patient satisfaction was lower with the pencil-point epidural needle compared to the Tuohy needle (75.5% vs. 92.2%, p0.03). There was no difference in complication rates from the CSE procedure between groups (pain, paresthesia, ADP, and PDPH). Conclusion In this pilot study, the use of the pencil-point epidural needle for CSE was associated with less successful epidural catheter placement as well as low user and patient satisfaction compared to the Tuohy epidural needle. Modifications in the pencil-point epidural needle design are needed to improve efficacy and enhance user acceptance before a larger study can be conducted to evaluate the rates of ADP and PDPH.

Pain management, as a key component of enhanced recovery after surgery (ERAS), can effectively relieve perioperative pain and anxiety. However, there are few studies on the application of pain management based on ERAS in pediatric surgery patients. We aimed to examine the effect of ERAS-based perioperative pain management in children with obstructive sleep apnea (OSA) undergoing adenotonsillectomy.

Vulvar Basal Cell Carcinoma (BCC) accounts for only 0.4% of all BCCs. We present a case of BCC that developed on the vulvar area with a pinkish lesion and pruritus for about 2 years and was successfully treated with Mohs micrographic surgery.

Epidural analgesia could influence the postoperative oncologic outcomes in patients with specific types of non-metastatic solid neoplasms. The present study aimed to investigate the impact of anesthetic technique on survival in elderly patients with ovarian cancer (OC). The records of all women with OC older than 60 years of age undergoing tumor debulking surgery at the University Medical Center of the Johannes Gutenberg University Mainz (Mainz, Germany) between January 2008 and December 2019 were obtained. The study cohort was divided into two groups based on the use of perioperative epidural anesthesia or not. First, Kaplan-Meier analysis was performed to analyze the prognostic influence of anesthetic technique on survival. Second, multivariate Cox proportional hazards model was adjusted for multiple conventional prognostic factors concerning three main categories: i) Current clinical-pathological tumor characteristics; ii) anesthesiologic parameters, including mean age, American Society of Anesthesiologists Performance Status and preexisting comorbidities summarized in the Charlson Comorbidity Index; and iii) oncological and surgical parameters such as oncological radicality and Surgical complexity Score. A total of 110 patients were included in the study and 71 (64.5%) of them received epidural analgesia. The median survival time was 26.0 months from primary debulking surgery and no significant differences in progression-free (PFS) and overall survival (OS) were noted between the 'Epidural' and 'non-Epidural' cohorts. After adjustment for the selected risk factors from the three categories, the effects of epidural analgesia on PFS and OS remained non-significant [PFS: hazard ratio (HR), 1.26; 95% CI, 0.66-2.39; and OS: HR, 0.79; 95% CI, 0.45-1.40]. The present results did not support the independent association between epidural-supplemented anesthesia and improved PFS or OS in elderly patients with standardized ovarian cancer debulking surgery.

Ramsay Hunt syndrome, a late manifestation of varicella-zoster virus infection, occurs when the virus reactivates, infects, and produces an inflammatory reaction in the seventh cranial nerve geniculate ganglion. The detection is made clinically on the basis of the following three features: facial nerve palsy, the presence of characteristic herpetic vesicles around the mouth, and pain in the ear. However, it is often diagnosed quite late and sometimes even missed, increasing the chances of complications that have long-term effects. The two significant complications following the development of Ramsay Hunt syndrome are facial nerve palsy and hearing impairment. Ramsay Hunt syndrome is among the principal causes of facial nerve palsy, implicated in around 2-10% of all cases. While hearing loss though prevalent, is a less common complication than facial palsy. This review aimed to analyze the clinical presentation and prognostic features of the complications of Ramsay Hunt syndrome mentioned above, that is, hearing loss and facial nerve palsy. It was seen that while the association of Ramsay Hunt syndrome with facial nerve palsy has been studied quite extensively, the literature on hearing loss as a sequela is quite lacking. The course and outcome of facial nerve palsy is determined by the early clinical picture, while the otological symptoms rely on the extent of nerve involvement. Early diagnosis and treatment go a long way in preventing these complications and increasing the chances of complete recovery. Treatment options most commonly studied included antiviral drugs such as acyclovir, steroids, and anti-inflammatory agents.

To find out the anatomic variations of nose/paranasal sinuses and how they affect the sinuses in chronic rhinosinusitis (CRS). This observational cross-sectional study included adults with CRS, refractory to optimum medical management, planned for functional endoscopic sinus surgery (FESS). Pre-operative naso-endoscopy and computed tomography (CT) were utilized to estimate the extent of CRS, and to note the anatomic variations of the sinuses. The findings were corroborated within the practical scope of FESS. The anatomic variations were evaluated to establish how they affected the related sinus(es). Most of the 53 patients were young adults presenting with nasal obstruction (77%), discharge (76%) and headache (68%). On diagnostic naso-endoscopy, prominent agger bulge (83% of the nasal sides), prominent uncinate (18%), inferior turbinate hypertrophy (34%), concha bullosa (38%), mucopus and polyp in the middle meatus (51%, 19%; respectively), and gross septal deviation (55%) were noted. The spheno-ethmoid and frontal recesses were predominantly unremarkable. CT revealed inferior turbinate hypertrophy (38% of the nasal sides), agger (100%), and lateralized/collapsed uncinate (8%). Ethmoids and maxillary sinuses were diseased in 50% and 65% respectively, with blocked ostiomeatal complex in 32% and prominent bulla in 48%. Frontal and sphenoid sinuses were least involved (10%, 2%; respectively). Enlarged agger caused maxillary sinusitis (87%), whereas anterior ethmoiditis resulted from enlarged agger (100%), bulla (89%) and frontal cells (51%). Identification of the anatomic variations of the nose/paranasal sinuses through CT and naso-endoscopy (diagnostic, per-operative) is crucial to understand the pattern, extent and severity of the involvement of sinuses in CRS.

This study aimed to investigate the relationships of lumbar spine-hip discoordination during sit-to-stand (STD) and stand-to-sit (SIT) with pain and functional disability in chronic nonspecific low back pain (CNLBP) patients.
