How uncomplicated total thyroidectomy could aggravate the laryngopharyngeal reflux disease?

Swallowing, voice disorders, throat discomfort and subjective neck discomfort are usually reported by patients with a known thyroid nodule and are correlated to nodular thyroid disease itself. Moreover, in endemic goitrous areas, total thyroidectomy (TT) is the most frequently performed surgical procedure. We are used to relate swallowing, voice and throat discomfort to the mechanical effects of nodular goiter or to thyroidectomy itself, but in both these cases the relationship between symptoms and the thyroid mass or its removal is not always clear or easily demonstrated. How can we explain the persistence of local neck symptoms after TT? And how can TT worsen the dysphagic or dysphonic disorders attributed to the goiter’s effect over the surrounding structures? During these years, many articles have analyzed the relationship between the thyroid disease and the laryngopharyngeal reflux, finding more and more evidences of their consensuality, leading to important new management considerations and notable medico-legal implications; if the reason of local neck symptoms is not the thyroid disease, we have to study and specially cure the reflux disease, with specific test and drugs. Therefore, the aim of our study, relying on the published literature, was to investigate how, in demonstrated presence of reflux laryngopharyngitis in patients with nodular goiter and local neck symptoms before and after uncomplicated TT, the surgery could influence our anti-reflux mechanism analyzing the anatomical connection as well as the functional coordination; can we play a part in the post-operative persistence of swallowing and voice alterations and throat discomfort

Two cases of monomicrobial intraabdominal abscesses due to KPC - 3 Klebsiella pneumoniae ST258 clone

<p>Abstract</p> <p>Background</p> <p>Knowledge of the etiology of pyogenic liver and pancreatic abscesses is an important factor in determining the success of combined surgical and antibiotic treatment. Literature shows geographical variations in the prevalence and distribution of causative organisms, and the spread of <it>Klebsiella pneumoniae </it>carbapenemase-producing bacteria is an emerging cause of abdominal infections.</p> <p>Case presentation</p> <p>We herein describe two cases of intra-abdominal abscesses due to monomicrobial infection by <it>Klebsiella pneumoniae </it>Sequence Type 258 producing <it>K. pneumoniae </it>carbapenemase 3 (KPC-Kp). In case 1, a 50-year-old HIV-negative Italian woman with chronic pancreatitis showed infection of a pancreatic pseudocystic lesion caused by KPC-Kp. In case 2, a 64-year-old HIV- negative Italian woman with pancreatic neoplasm and liver metastases developed a liver abscess due to KPC after surgery. Both women were admitted to our hospital but to different surgical units. The clonal relationship between the two isolates was investigated by pulsed-field gel electrophoresis (PFGE). In case 2, the patient was already colonized at admission and inter-hospital transmission of the pathogen was presumed. A long-term combination regimen of colistin with tigecycline and percutaneous drainage resulted in full recovery and clearance of the multidrug-resistant (MDR) pathogen.</p> <p>Conclusions</p> <p>Timely microbiological diagnosis, the combined use of new and old antibiotics and radiological intervention appeared to be valuable in managing these serious conditions. The emergence and dissemination of MDR organisms is posing an increasing challenge for physicians to develop new therapeutic strategies and control and prevention frameworks.</p

Local neck symptoms before and after thyroidectomy: a possible correlation with gastroesophageal reflux and reflux laryngopharingitis.

P02.25 LOCAL NECK SYMPTOMS BEFORE AND AFTER THYROIDECTOMY: A POSSIBLE CORRELATION WITH GASTROESOPHAGEAL REFLUX AND REFLUX LARYNGOPHARYNGITIS. Alessia Cusimano1, Achille Mastrosimone2, Eugenio Fiorentino1 1Policlinico Of Palermo, Palermo/ITALY, 2Policlinico Of Palermo, Agrigento/ITALY Background: Swallowing, voice disorders and throat discomfort are usually reported by patients with a thyroid nodule. it may frequently occur in patients who have undergone uncomplicated TT complain of symptoms such as swallowing disorders, hoarseness, a sensation of strangling or of a lump in the neck, a cough and sore throat, all usually attributed to oro- tracheal intubation. Swallowing, voice and throat discomfort should thus be in some way related to the mechanical effects of nodular goiter or to thyroidectomy; it has never been suggested that the same symptoms might refer to a different concomitant medical problem with an overlapping clini- cal presentation. Reflux laryngopharyngitis is the most frequent caused by the laryngopharyngeal reflux (LPR), a term which refers to the backflow of gastric juice into the laryngopharynx. LPR has been considered one of the atypical clinical presentations of gastroesophageal reflux (GER) affecting the larynx and pharynx; several otolaryngologists maintain that LPR differs from GER and concerns reflux in otolaryngology patients more often in the absence of gastrointestinal symptoms. Methods: in a period of 6 months, 144 patients undergone to TT, interviwed according to the Reflux Symptome Index, investigated through videolaryn- goscopy and videofluoroscopic swallowing studies Results: 3 months after surgery, swallowing and voice disorders and throat discomfort symptoms persisted in a large number of patients, associated with the laryngopharyngitis revealed by the findings at VLS and alterations at VFSS. Discussion: this is the first study correlating local neck symptoms in patients with non-toxic nodular goiter to refextra-esophageal reflux, a new hypothesis.

Gastrooesophageal reflux and "Epileptic" attacks: casually associated or related? Efficiency of antireflux surgery, a case report

P02.30 GASTRO-OESOPHAGEAL REFLUX AND “EPILEPTIC” ATTACKS: CASUALLY ASSOCIATED OR RELATED? EFFICIENCY OF ANTIREFLUX SURGERY A CASE REPORT Achille Mastrosimone1, Alessia Cusimano2, Silvia Marino2, Gianni Pantuso2, Eugenio Fiorentino2 1Policlinico Of Palermo, Palermo/ITALY, 2University Of Palermo, Palermo/ITALY Background: Although a possible link between gastro-oesophageal reflux disease (GORD) and obstructive sleeping apnoea has already been reported in the literature, there has never been any suggestion of an association with epilepsy, and epileptic attacks have not so far been included among gastro- oesophageal reflux disease symptoms. Methods: We report the case of a patient with gastro-oesophageal reflux disease associated with a sliding hiatus hernia, a short oesophagus and oesoph- agitis, who for the last ten years had not only presented the typical symptoms of gastrooesophageal reflux, but also symptoms of obstructive sleep apnoea and epileptic- like attacks occurring occasionally and only during sleep. Results: Partial posterior fundoplication was performed and considerably reduced the reflux symptoms, and in addition brought about a drastic decrease in the number of epileptic-like attacks. Discussion: Our case suggests that epileptic-like episodes in patients with obstructive sleeping apnoea may well be linked to the simultaneous presence of GORD associated with hiatus hernia, and surgical treatment of GORD may bring about an improvement of the neurological problems.

Selective killing of spinal cord neural stem cells impairs locomotor recovery in a mouse model of spinal cord injury

Abstract Background Spinal cord injury (SCI) is a devastating condition mainly deriving from a traumatic damage of the spinal cord (SC). Immune cells and endogenous SC-neural stem cells (SC-NSCs) play a critical role in wound healing processes, although both are ineffective to completely restore tissue functioning. The role of SC-NSCs in SCI and, in particular, whether such cells can interplay with the immune response are poorly investigated issues, although mechanisms governing such interactions might open new avenues to develop novel therapeutic approaches. Methods We used two transgenic mouse lines to trace as well as to kill SC-NSCs in mice receiving SCI. We used Nestin CreERT2 mice to trace SC-NSCs descendants in the spinal cord of mice subjected to SCI. While mice carrying the suicide gene thymidine kinase (TK) along with the GFP reporter, under the control of the Nestin promoter regions (NestinTK mice) were used to label and selectively kill SC-NSCs. Results We found that SC-NSCs are capable to self-activate after SCI. In addition, a significant worsening of clinical and pathological features of SCI was observed in the NestinTK mice, upon selective ablation of SC-NSCs before the injury induction. Finally, mice lacking in SC-NSCs and receiving SCI displayed reduced levels of different neurotrophic factors in the SC and significantly higher number of M1-like myeloid cells. Conclusion Our data show that SC-NSCs undergo cell proliferation in response to traumatic spinal cord injury. Mice lacking SC-NSCs display overt microglia activation and exaggerate expression of pro-inflammatory cytokines. The absence of SC-NSCs impaired functional recovery as well as neuronal and oligodendrocyte cell survival. Collectively our data indicate that SC-NSCs can interact with microglia/macrophages modulating their activation/responses and that such interaction is importantly involved in mechanisms leading tissue recovery
