Current trends in tonsillitis and tonsillectomy

IntroductionThe aim of this study was to assess tonsillitis and tonsillectomy trends, both from a local and national perspective.MethodsRetrospective analysis was carried out of tonsillitis admissions and tonsillectomy rates over a ten-year period in a university teaching hospital from 2003 to 2012.ResultsSince 2003 tonsillitis admissions have increased locally by 118% in adults and 179% in children despite negligible changes in tonsillectomy rates. Similar trends have been observed nationally.ConclusionsThe findings of this study may be considered to be the result of current National Health Service policy. A reconsideration of agreed indications for tonsillectomy could potentially reduce hospital admissions of patients with tonsillitis in the long term.     

Acute cervical osteomyelitis and prevertebral abscess after routine tonsillectomy

BACKGROUND CONTEXT: Tonsillectomy is among the most commonly performed surgical procedures. The development of severe infection after tonsillectomy is a very rare but potentially fatal complication that has not been described in the orthopedic, neurosurgical, or spine literature. PURPOSE: To present acute cervical osteomyelitis and prevertebral abscess formation as a complication of a routine tonsillectomy. STUDY DESIGN: Case report, literature review. METHODS: A case report was prepared on the clinical and radiographic data of a patient presenting with prevertebral abscess and acute cervical osteomyelitis 6 weeks after routine tonsillectomy. A review of relevant literature was additionally performed. RESULTS: The patient presented 6 weeks after tonsillectomy with evidence of a deep cervical infection. Operative debridement with anterior and posterior surgical stabilization was performed. The patient completed a 6-week course of intravenous antibiotics. At 24-month follow-up, the patient showed no signs of infection and demonstrated a stable fusion mass. CONCLUSIONS: The development of prevertebral abscess and acute cervical osteomyelitis has been discussed in a small number of otolaryngology case reports and has not been previously reported in the orthopedic, neurosurgical, or spine literature. Symptoms may be nonspecific, and so a high index of clinical suspicion is needed. Delay in treatment may lead to significant morbidity and even mortality. Successful treatment can be obtained through operative debridement and intravenous antibiotic therapy.     

Intracerebral Aspergillus abscess: Case report and review of the literature

Intracranial aspergillosis is a rare pathologic condition, difficult to treat and often fatal, which generally affects immunodepressed patients. A case of brain abscess secondary to pulmonary localization in a patient with a non-Hodgkin lymphoma is described. The most significant clinico-pathological findings of intracranial aspergillosis are examined in the light of the relevant literature.     

The rising rate of admissions for tonsillitis and neck space abscesses in England, 1991–2011

Introduction

Sore throats and tonsillitis represent a considerable health burden as well as a significant source of expenditure for the National Health Service (NHS). As part of the recent NHS savings drive, the introduction of ‘procedures of low clinical effectiveness’ (PoLCE) lists has reinforced a large reduction in the number of tonsillectomies performed. We carried out a cross-sectional study of trends in emergency sore throat admissions in the context of the number of tonsillectomies performed.

Methods

Hospital Episode Statistics (HES) data were extracted. Office for National Statistics data were also used.

Results

Between 1991 and 2011, the overall tonsillectomy rate fell by 44%. In the same time, the admission rate for tonsillitis rose by 310% (Pearson’s r=–0.67, p=0.01). The peritonsillar abscess admission rate rose by 31% (r=–0.79, p<0.01). Between 1996 and 2011, the overall tonsillectomy rate fell by 41% and the retro and parapharyngeal abscess admission rate rose by 39% (r=–0.55, p=0.026). There was a 14% overall increase in tonsillectomy and sore throat associated bed days. This was despite the large fall in tonsillectomy numbers and the reduction in length of hospital stay.

Conclusions

Efforts to reduce the tonsillectomy rate are correlated with a significant rise in emergency admissions. The rise in the retro and parapharyngeal abscess rate is perhaps most alarming given the very high mortality of these conditions. Bed day data suggest that no net saving has been made despite the new measures.     

Xanthogranulamatous pyelonephritis with psoas abscess: 2 cases and review of the literature

Xanthogranulomatous pyelonephritis (XGP) is a rare form of chronic pyelonephritis. With the review of the literature, we reported two cases of XPN with psoas muscle abscesses caused by Staphylococci aereus in one of the patient and Serratia mascerentes in the other. Both of the patients had renal calculus. We performed nephrectomy with psoas abscess drainage and started appropriate antibiotics, but one of the patients died of septic shock. Other patient is free of symptoms at the end of 5 years follow-up.     

Asymptomatic brain abscess as a complication of halo orthosis: Report of a case and review of the literature

The halo external orthosis has been used extensively for cervical immobilization after spine surgery or trauma, usually without serious complications. However, nine brain abscesses have been reported as complications following the use of halo orthosis. We report on a 53-year-old man who underwent anterior cervical fusion for cervical myelopathy, followed by the application of a halo orthosis. Approximately 4 weeks postfusion, loosening of the right anterior pin was recognized and the pin was tightened, as the pin-site was clean. One week later, purulent material was discharged from the pin hole when the pin was removed after it had loosened again. Enhanced computed tomography (CT) demonstrated an abscess on the right side of the brain. After the administration of antibiotics, the abscess resolved without surgical intervention. We describe asymptomatic brain abscess complicating the use of a halo orthosis and review the clinical features, symptoms, and outcomes; we also discuss the mechanism that induced brain abscess. Most reported cases of abscess have been associated with pin-site infection or tightening after late pin loosening. The present case indicates the importance of early recognition of symptoms and signs associated with brain abscess in patients with a halo orthosis.

Haematoma and abscess after neuraxial anaesthesia: a review of 647 cases

Although rare, spinal haematoma and abscess after central neuraxial blocks may cause severe permanent neurological injury. Optimal treatment and outcome remain unclear. In order to identify possible predisposing patient characteristics and describe the ensuing clinical course, we searched Medline, Embase, and the Cochrane Library for reports of spinal haematomas and abscesses associated with central neuraxial blocks. Extracted data included patient characteristics, symptoms, treatment, and outcome. We analysed 409 reports, including 647 patients (387 patients with spinal haematoma and 260 patients with spinal abscess). Spinal haematoma and abscess occurred predominantly after epidural anaesthesia (58% and 83%, respectively). Neurological recovery was correlated with the severity of initial neurological deficit. When decompression of spinal haematoma was delayed for >12 h after clinical diagnosis, neurological outcome was worse compared with earlier decompression (odds ratio 4.5, 95% confidence interval 2.1–9.9, P<0.001, n=163). After spinal haematoma, 47% of published patients had full recovery, 28% had partial recovery, and in 25% no recovery was observed. Good outcome after conservative management was observed in patients with mild symptoms or with spontaneous recovery during the diagnostic and therapeutic workup. After spinal abscess, 68% of reported patients recovered fully, 21% showed partial recovery, and no recovery was reported in 11%. Persistent neurological symptoms after spinal haematoma and abscess are common and correlate with the severity of initial neurological deficit. Neurological outcome seems worse when decompressive surgery of haematoma is delayed. Notwithstanding the considerable risk of selection bias and publication bias, conservative management may be feasible in patients with mild symptoms or spontaneous recovery.     

Endoscopic treatment of pituitary abscess: two case reports and literature review

Pituitary abscess is a rare entity and the correct diagnosis is still difficult before surgery. More than 210 cases have been reported in the medical literature, mostly in the form of isolated case reports. We report two cases of pituitary abscess treated endoscopically and we review the literature. A 30-year-old woman and a 35-year-old man were admitted with a history of pituitary dysfunction. Patient 1 presented with polyuria, polydipsia, amenorrhea, headache, and visual impairment. Magnetic resonance imaging showed a cystic intra- and supra-sellar lesion with ring enhancement after contrast injection. Patient 2 presented with frontal headache, proptosis, painful ophthalmoplegia, visual impairment, and fever. Eight years before the patient had undergone a transphenoidal surgery for Prolactinoma. Magnetic resonance imaging revealed a sellar lesion extending into the cavernous sinus and carotid artery bilaterally. Both patients underwent endoscopic transnasal-transsphenoidal exploration. Intraoperative diagnosis of pituitary abscess was made. The postoperative courses were uneventful. Antibiotic therapy was performed in both cases. Only three cases of endoscopic treatment of pituitary abscess have been reported in the literature. We recommend early management by endoscopic transphenoidal surgery for pituitary abscess: this technique is safe, with minimal blood loss, short operating time, low morbidity, and brief hospital stay.     

Intra-abdominal abscess due to patient non-compliance after construction of an ileal neobladder: Case report and review of the literature

PURPOSE: A case report of patient with an intra-abdominal abscess 8 weeks after radical cystectomy and construction of an ileal neobladder is presented. METHODS/RESULTS: The patient was admitted with nausea, vomiting and singultus. A perforation of the neobladder due to overdistension was assumed to be the underlying cause of the intra-abdominal abscess formation as the patient admitted infrequent voiding during the day and no emptying of the neobladder at night. The patient underwent explorative laparotomy and 4200 mL of pus was removed from the abdominal cavity. The patient made an uneventful recovery and was discharged from hospital after 5 weeks. Neobladder function remained stable and the patient was leading a normal life at 24 months follow-up. CONCLUSIONS: The present case demonstrates the need for careful patient selection prior to radical cystectomy with continent urinary diversion. Reduced compliance and mental disabilities of a patient can increase the complication rate.     

Non-traumatic rupture of voluminous non-typhoid Salmonella splenic abscess presenting with peritonitis: Case report and review of the literature

Introduction and importanceSplenic abscess (SA) is an uncommon, life-threatening disease with about 600 reported cases in the literature. It is caused by various infective pathogens and generally occurs in immunocompromised patients. SA is a rare complication of non-typhoid Salmonella (NTS) infection. Diagnosis of ruptured SA is a challenge because the absence of specific symptoms and signs. Abdominal computed tomography (CT) scan represents the gold standard in diagnosing of SA. Splenectomy is the treatment of choice of ruptured SA with peritonitis.Case presentationA 26-year-old Caucasian female was admitted to the Emergency Department with a three-day history of abdominal pain and fever. Physical examination revealed severe and generalized abdominal pain on superficial and deep palpation with obvious muscle guarding and rebound tenderness. Abdominal CT scan showed ruptured SA. Laboratory tests reported anemia (hemoglobin 10.4 g/dl). The patient was taken emergently to the operating room for splenectomy. The postoperative course was uneventful, the patient was discharged on the 7th post-operative day. Diagnosis of NTS SA was made by pus cultures.Clinical discussionSA is a rare complication of NTS infection associated with high morbidity and mortality rates. Although different types of treatment of SA are reported in the literature, splenectomy represents the treatment of choice of ruptured SA.ConclusionNTS SA is difficult to diagnose because of its rarity and non-specific clinical presentation, often fatal if left untreated. Although there is no gold standard for treating SA, splenectomy with peritoneal lavage is mandatory in case of ruptured SA with peritonitis.     

Spontaneous urinoma debuting as retroperitoneal abscess: report of 2 cases and literature review

Spontaneous urinoma is a urological entity that can be complicated by a retroperitoneal abscess. Urinoma can be iatrogenic, traumatic, or can be caused by obstructive uropathy. We report two cases of spontaneous urinomas, describing a not previously published cause of urinoma: pyeloureteritis. (I) A 55-year-old Caucasian female started with intense left-sided flank pain for 3 days. CT scan revealed a voluminous retroperitoneal abscess, which extended through the posterior pararenal space and the left lumbar paravertebral musculature. (II) A 48-year-old Caucasian male presented with constitutional symptoms over the previous 2 months and investigations showed a voluminous urinoma and marked pyeloureteritis findings on CT scan. Both patients were managed by endoscopic placement of a double-J stent and drainage of the collection (open and percutaneous approach, respectively). Urinoma was confirmed by fluid biochemical analysis, which demonstrated that fluid creatinine was markedly raised as compared to the serum creatinine. Urinoma in the absence of obstruction or trauma is rare. These two case reports highlight one of the conditions leading to urinoma and the management of retroperitoneal abscess. Pyeloureteritis is a cause of spontaneous urinoma and it should be considered in the lack of another obstructive cause.     

Complications after pancreaticoduodenectomy: intraabdominal abscess

The development of intraabdominal abscess (IAA) following pancreaticoduodenectomy (PD) is an important problem. It is a common cause of readmission to the hospital following discharge. Rates of IAA do not appear to depend on whether the pancreas is anastomosed to the stomach or jejunum, nor whether a duct-to-mucosa or invagination technique is used. Most surgeons favor the use of closed-suction drains after PD. The use of fibrin glue sealant does not appear to reduce the rate of IAA. The use of preoperative biliary stenting increases wound infection rates, but not IAA rates. The use of internal and external pancreatic duct stents with PD to prevent IAA have yielded mixed results.     

Odontoid-sparing transnasal approach for drainage of craniocervical epidural abscess; a novel technique and review of the literature

Background Context

Surgical approaches to the craniovertebral junction (CVJ) are challenging. Available approaches include posterior, transoral, endonasal, and anterior extended retropharyngeal approach. Resection of the odontoid process is necessary to gain access to the pathology posterior to it. The resultant cranio-atlanto-axial instability usually necessitates subsequent posterior stabilization.

Chronic intramedullary abscess (Streptococcus sanguis). A case report and review of the literature

OBJECTIVE: Chronic intramedullary spinal cord abscesses are very rare. We present here a new case of this pathology, revealed by a progressive spinal cord compression. This case is particular because of the long follow up before surgery (two years). CASE REPORT: This 69-year-old patient presented a gradually progressive paraparesis and sensory loss associated with leg pain. The past medical history was dominated by a epidermoid cancer of the tongue. MRI showed an intramedullary mass at T10. On the T1-weighted sequences, the lesion was isointense with the spinal cord, Gadolinium infusion showed homogeneous enhancement of the lesion. T2-weighted sequences showed decreased signal within the lesion and an increased signal peripherally (edema). Corticosteroid infusions relieved the symptoms so the patient declined surgery. Two episodes of regressive paraplegia were treated by the same infusions. The patient accepted surgery after a third episode. RESULTS: The intervention was performed two years after the first signs and revealed a hard white mass attached to the spinal cord. Pathologic examination showed infectious inflammation. Bacteriological cultures found a Streptococcus sanguis. Two years later the patient could walk; a minimal deficit persists. CONCLUSION: First, the diagnosis was evoked but not retained because of the long course. The corticosteroid infusions gave relief and did not increase the deficit. The MRI findings remained unchanged. Intramedullary spinal cord abscesses are very rare. This pathology must be recognized because without treatment morbidity is high with a potentially fatal outcome.     

Nocardia brain abscess mimicking brain tumour in immunocompetent patients: report of two cases and review of the literature

Summary Nocardia brain abscess is a rare intracranial lesion and has been reported in immunocompromised patients. An optimal treatment approach has not been established. However, early diagnosis and appropriate antimicrobial therapy are very important factors for a good outcome. We report two unusual cases of Nocardia brain abscess simulating brain tumour in immunocompetent patients. One of the cases was presumed to be a primary brain tumour and the other a metastatic brain tumour. They underwent surgical gross total resection. After Nocardia asteroides was seen on Grams stain and subsequently identified by culture, appropriate antibiotic therapy was initiated.
