A retrospective observational study of people with Type 1 diabetes with self-reported severe hypoglycaemia reveals high level of ambulance attendance but low levels of therapy change and specialist intervention.

AIM: To evaluate the impact of severe hypoglycaemia on NHS resources and overall glycaemic control in adults with Type 1 diabetes. METHODS: An observational, retrospective study of adults (aged ≥ 18 years) with Type 1 diabetes reporting one or more episodes of severe hypoglycaemia during the preceding 24 months in 10 NHS hospital diabetes centres in England and Wales. The primary outcome was healthcare resource utilization associated with severe hypoglycaemia. Secondary outcomes included demographic and clinical characteristics, diabetes control and pathway of care. RESULTS: Some 140 episodes of severe hypoglycaemia were reported by 85 people during the 2-year observation period. Ambulances were called in 99 of 140 (71%) episodes and Accident and Emergency attendance occurred in 26 of 140 (19%) episodes, whereas 29 of 140 (21%) episode required no immediate help from healthcare providers. Participants attended a median of 5 (range 0-58) diabetes clinic consultations during the observation period; 13% (70 of 552) of all consultations were severe hypoglycaemia-related. Of the HbA1c measurements recorded closest prior to severe hypoglycaemia (n = 119), only 7 of 119 measurements were < 48 mmol/mol (< 6.5%) and mean HbA1c was 70 (sd 19) mmol/mol (8.5%, sd 1.7%). Some 119 changes to diabetes treatment were recorded during the observation period (median/person 0;, range 0-11), of which 52 of 119 changes (44%) followed severe hypoglycaemic events. CONCLUSIONS: We observed a high level of ambulance service intervention but surprisingly low levels of hypoglycaemia follow-up, therapy change and specialist intervention in people self-reporting severe hypoglycaemia. These results suggest there may be important gaps in care pathways for people with Type 1 diabetes self-reporting severe hypoglycaemia.

Bethesda 2014: improving on a paradigm shift.

The third iteration of the Bethesda System terminology manual was recently published. This update included changes in the reporting of benign endometrial cells, and guidance for special adequacy situations and for cases in which low grade squamous intraepithelial lesions are accompanied by some cells suggesting that a high grade lesion might also be present. In addition, the manual was increased in size to include more illustrations with special studies and comparisons to histology, a greatly increased reference list, and a new chapter devoted to the modern practice of risk-based management. The third edition of the Bethesda manual is meant to serve as a primary reference for the practice of gynecologic cytology designed to provide a uniform system of reporting Worldwide for clinical, teaching, and research purposes.

Training and practice of cytotechnologists: a discussion forum focused on Europe.

OBJECTIVES: To discuss the role and training of cytotechnologists (CTs) in Europe, to identify areas of good practice and to provide an informed opinion to those providing guidelines for training and practice in Europe. METHODS: All members of the Editorial Advisory Board of Cytopathology were invited to take part in a 'discussion forum' for which six topics were circulated in advance concerning the roles of CTs with regard to: (1) pre-screening slides; (2) 'signing out' reports; (3) carrying out ancillary techniques; (4) supervising laboratory staff; (5) taking part in rapid on-site evaluation (ROSE) of fine needle aspirates (FNAs); and (6) whether CTs were trained specifically in cytopathology or in general histopathology. Notes of the meeting were circulated by email and a final report was agreed by 22 participants from 17 predominantly European countries. RESULTS: Training for CTs throughout Europe was variable, especially for non-gynaecological cytology, which was inconsistent with the range of activities required. The participants recommended graduate entry, preliminary training in general laboratory technology, and subsequent training to take account of the probability and, in some centres, the reality of primary cervical cancer screening changing from cytology to human papillomavirus (HPV) testing. They further recommended that CTs should perform HPV tests and take part in ROSE for FNAs, and they supported the European Federation of Cytology Societies developing guidelines for training and practice. CONCLUSION: With CT training added to a university-based education in laboratory or biomedical science, a career in cytotechnology should be an attractive option involving a diverse range of laboratory and clinically based activities.

Fifteen-year trends and predictors of preparation for pregnancy in women with pre-conception Type 1 and Type 2 diabetes: a population-based cohort study.

AIMS: To investigate trends in indicators of preparation for pregnancy in women with Type 1 and Type 2 diabetes and explore their predictors. METHODS: Data on 2293 pregnancies delivered during 1996-2010 by women with Type 1 (n = 1753) and Type 2 (n = 540) diabetes were obtained from the Northern Diabetes in Pregnancy Survey. Multiple logistic regression was used to analyse the relationship between potential predictors and three indicators of inadequate pregnancy preparation: non-attendance for pre-conception care; no pre-conception folate consumption; and peri-conception HbA(1c) ≥ 53 mmol/mol (≥ 7%). RESULTS: Overall, 40.3% of women with diabetes attended pre-conception care, 37.4% reported pre-conception folate consumption, and 28.2% had adequate peri-conception HbA1c . For all patients, pre-conception folate consumption improved over time, while peri-conception glucose control did not. Attendance for pre-conception care for women with Type 1 diabetes significantly declined. Residence in deprived areas, smoking and younger maternal age (for women aged < 35 years) were independently associated with all three indicators of inadequate preparation for pregnancy. Additional predictors of inadequate peri-conception HbA(1c) were: Type 1 diabetes (adjusted odds ratio 5.51, 95% CI 2.71-11.22), longer diabetes history (adjusted odds ratio 1.16, 95% CI 1.09-1.23 per year increase for those with < 15 years' diabetes duration), non-white ethnicity (adjusted odds ratio 3.13, 95% CI 1.23-7.97) and higher BMI (adjusted odds ratio 1.05, 95% CI 1.01-1.09 per 1-kg/m(2) increase). Non-attendance for pre-conception care was additionally associated with Type 2 diabetes (P = 0.003) and multiparity (P < 0.0001). CONCLUSIONS: There are socio-demographic inequalities in preparation for pregnancy among women with diabetes. Women with Type 2 diabetes were less likely to attend pre-conception care. Pre-conception services need to be designed to maximize uptake in all groups.

Cupriavidus pauculus (Ralstonia paucula) concomitant meningitis and septicemia in a neonate: first case report from India.

Ralstonia paucula (formerly classified as CDC (Centre for Disease Control) group IVc-2, Wautersia paucula; recently renamed as Cupriavidus pauculus) is an environmental Gram-negative bacillus isolated from water sources and can cause serious human infections. Patients recover bacteriologically indicating low virulence. A total of 32 cases have been reported world-wide, but no isolation has ever been reported from cerebrospinal fluid or in India. The first case of R. paucula meningitis and septicemia is being reported here along with the brief summary of cases reported world-wide.

Do patients with allergic rhinitis have a particular personality trait?

OBJECTIVES: This study investigated the personality traits of patients with allergic rhinitis. It also examined the association between personality type and the type of allergic rhinitis, and compared this with the general population. METHODS: A descriptive observational pilot study was carried out on 50 consecutive cases of allergic rhinitis who presented to the allergy clinic between June and October 2010. These patients were compared with a control group comprising 50 individuals from the general population that had no symptoms of allergic rhinitis. Both groups completed the International Personality Disorder Examination questionnaire for the assessment of personality traits. RESULTS: Persons falling into cluster C personality type showed a positive correlation with the type and severity of allergic rhinitis. The majority of control group individuals fell into cluster A. This indicated a correlation between allergic rhinitis and a dominant anxious trait compared with the control group. CONCLUSION: In psycho-allergological research, the potential relevance of personality factors in the maintenance and exacerbation of atopic symptoms is still a matter of debate. More attention should be paid to the psychological status of allergic rhinitis patients, and appropriate treatment should be provided to improve their symptoms and quality of life.

Thyroid Bethesda reporting category, 'suspicious for papillary thyroid carcinoma', pitfalls and clues to optimize the use of this category.

OBJECTIVE: The Bethesda System of Reporting Thyroid Cytopathology classifies the indeterminate categories based on their differing risks of malignancy, as atypia of undetermined significance (AUS), follicular neoplasm/suspicious for follicular neoplasm (FLUS) and suspicious for malignancy. The vast majority of cases of the last category are suspicious for papillary thyroid carcinoma (PTC). The aim of the present study was to identify the pitfalls and clues to improve the usage of the suspicious category as well as improve its outcome of malignancy. METHODS: We reviewed the cytological features on air dried Diff-Quik® and alcohol-fixed Papanicolaou smears from 54 thyroid fine needle aspirates (FNAs) with surgical follow-up that were originally diagnosed as suspicious. Procedure data/specimen adequacy was correlated and follow-up histology reports were reviewed after our cytological review was completed. Incidental PTC that was not the target of the FNA was excluded from the calculations for correlation. RESULTS: In our cytological review, we retained a diagnosis of suspicious in 18 of the 54 cases and the remaining 36 were re-categorized as follows: 6 malignant, 10 neoplasm (which is used in our centre instead of FLUS) and 20 AUS. The reasons for overcall of suspicious cases included pseudopapillae, syncytial sheets, nuclear grooves and pinpoint nucleoli in chronic lymphocytic thyroiditis and Hürthle cell neoplasms, and intranuclear inclusions in parathyroid adenoma, hyalinizing trabecular adenoma and mesenchymal repair. The primary reasons for undercall of PTC as suspicious included cystic aspirates with minor features of PTC such as histiocytoid cells, bubblegum colloid, syncytial sheets and cellular swirls. Cases with cytoplasm similar to Hürthle cells were also noted to cause difficulty in accurate classification. CONCLUSIONS: Recognition of these pitfalls and clues can help improve diagnosis, patient treatment and consequently reduce the number of unnecessary thyroidectomies.

Tracheal resection with end-to-end anastomosis for post-intubation cervical tracheal stenosis: study of 14 cases.

BACKGROUND AND OBJECTIVES: The incidence of acquired laryngeal stenosis is increasing. This retrospective study aimed to assess the long term results of circumferential resection with end-to-end tracheal anastomosis for isolated post-intubation stenosis of the cervical trachea, and to review the relevant literature. METHODS: Twelve male and two female patients (aged 16-30 years, mean age 24 years) treated between February 2003 and December 2008 were included. Hospital and office records were reviewed and relevant surgical details recorded. RESULTS: Indications for tracheal resection anastomosis were post-intubation stenosis (78.57 per cent) and trauma (21.42 per cent). One to five tracheal rings were resected (i.e. 1-2.5 cm of cervical trachea). Tracheal anastomosis was considered successful if the patient remained asymptomatic for 24 months of close follow up (involving regular flexible bronchoscopy and neck X-ray). The anastomotic success rate was 92.85 per cent. CONCLUSION: Tracheal resection and end-to-end anastomosis is relatively safe and reliable for definitive treatment of benign tracheal stenosis in appropriate patients. Local application of mitomycin C prevents granulation and aids long term airway patency.

Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA): experience of an academic centre in the USA.

OBJECTIVES: Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has become widely accepted as an effective modality for obtaining tissue for primary diagnosis and staging. We have been using EUS-FNA since July 2001 and herein we summarize our experience over a 5-year period. METHODS: A computer-based search for in-house EUS-FNA was performed in the pathology database from July 2001 to October 2006. To calculate the sensitivity, specificity and accuracy of EUS-FNA, the cytology diagnosis was compared with the surgical follow-up. RESULTS: A total of 951 EUS-FNAs were performed during the study period and included 279 pancreatic solid lesions, 186 pancreatic cyst lesions, 249 lymph node aspirations, 111 gastrointestinal (GI) tract submucosal lesions, and 126 miscellaneous lesions. EUS-FNA had a very high sensitivity and accuracy for solid pancreatic lesions (94.7 and 97.7%, respectively), low sensitivity and accuracy but high specificity (47, 64.8 and 95%, respectively) for cystic lesions. Cyst fluid carcinoembryonic (CEA) levels were significantly higher in mucinous neoplasms than non-neoplastic cysts. EUS-FNA also had very high sensitivity and specificity for detecting metastatic carcinoma in lymph nodes (95 and 100%, respectively). GI submucosal spindle cell tumours were further classified with immunohistochemical stains performed either on a cell block or a core biopsy obtained via EUS guidance. CONCLUSIONS: EUS-FNA has a very high sensitivity and accuracy for pancreatic solid lesions, but the sensitivity for cystic lesions is generally low. Cyst fluid chemical analysis for CEA is helpful, but the overlap between mucinous neoplasm and non-neoplastic cysts is significant. Recognizing GI contamination is important and immunohistochemical stains are useful for GI submucosal spindle cell lesions.

Does anesthetic induction for Cesarean section with a combination of ketamine and thiopentone confer any benefits over thiopentone or ketamine alone? A prospective randomized study.

BACKGROUND: The aim of this study was to evaluate the benefit of a combination of thiopentone and ketamine over either of these drugs alone as an induction agent for Cesarean section. METHODS: Randomized prospective study of 3 groups of 20 patients (Group I: thiopentone alone; Group II: ketamine alone; Group III thiopentone and ketamine combination). RESULTS: Systolic blood pressure (BP) (as measured at baseline, after induction, at intubation, and at 5 min, 10 min, 15 min, 20 min, 25 min, 30 min): baseline BP did not differ significantly across groups. However, postinduction values were significantly higher for Group II (ketamine alone) (P>0.001), but these values normalized by 30 min postinduction. Diastolic BP (as measured at baseline, after induction, at intubation, and at 5 min, 10 min, 15 min, 20 min, 25 min, 30 min): baseline BP did not differ significantly across groups. After induction, diastolic BP increased significantly in all groups. In Group I and Group III, these values returned to baseline after 10 min, and in Group II at the 30 min postinduction stage. Heart rate (measured at the same time as BP): at rest, presented no significant difference in heart rate across groups. At induction, all groups showed a significant rise in heart rate. At intubation, Group I showed an increase in heart rate, Group II a decrease in heart rate, and Group III no change. These intergroup variations were statistically significant. Apgar scores and umbilical venous gas measurements: although there were intergroup variations, these were not statistically significant. Postoperative pain assessment (subjective) VAS scores: the VAS pain scores 3 h after surgery were significantly higher in Group I, both at rest and coughing, at 24 h after surgery the difference persisted for scores at rest, but equalized during coughing. Postoperative pain assessment (objective) time to first analgesic demand: the duration of time to demand for first analgesic was significantly longer in Group II (ketamine only). Postoperative pain assessment (objective) total consumption of analgesic: patients of Group I consumed a significantly higher amount of analgesics than the other groups. Intraoperative event recall, awareness: no patient reported any adverse events of this nature. CONCLUSIONS: We conclude that though there were no adverse events and a significantly lower analgesic requirement, the use of ketamine alone as an induction agent in Cesarean section should be avoided, as it causes significant maternal hemodynamic changes. The addition of a reduced dose of ketamine to thiopentone in the induction cocktail confers the benefit of reducing analgesic requirement without side effects. The treatment is safe and effective for the mother and child.

Sublingual hydatid cyst: case report and literature review.

OBJECTIVES: To demonstrate the importance of detailed clinical analysis in the differential diagnosis of a cyst in the floor of the mouth, and to provide an update on current knowledge and treatment of sublingual hydatid cyst. CASE REPORT: A 23-year-old man presented complaining of a swelling in the midline of the sublingual region, present for four months and progressively increasing in size. Ultrasonography of the neck revealed a well defined, hypoechoic lesion in the sublingual region, containing a calcific focus. Fine needle aspiration cytology showed numerous round to oval structures resembling brood capsules, with scolices and occasional hooklets. T1- and T2-weighted, multiplanar magnetic resonance imaging scans showed a well defined, multiloculated lesion in the sublingual region. CONCLUSION: Hydatid disease may present as a slow-growing cyst in the sublingual region. Aspiration cytology should preferably be avoided until radiological imaging studies are complete. A high index of suspicion is necessary to diagnose hydatid disease in an unusual location.

The 'Sartorius Switch' and its relevance for the radiologist.

We report the case of a 43 year old female patient, who underwent a left groin dissection 5 years after her original diagnosis of a 3.8mm Breslow thickness malignant melanoma of her left leg, where the appearance of a post-operative computed tomography (CT) scan caused diagnostic misunderstanding. This case demonstrates the importance of providing the radiologists with accurate information regarding surgical procedures prior to imaging such that misinterpretations of this kind can be avoided. Whilst the detail of an operation may be obvious to the surgical team, one cannot expect radiologists to be aware of either standard procedural detail, or indeed new surgical developments.

Extracranial cysticercosis of the parotid gland: a case report with a review of the literature.

OBJECTIVE: A case of solitary extracranial cysticercosis of the parotid gland is reported. A discussion concerning the clinical features, imaging modalities, diagnostic methods and management of cysticercosis, along with a review of relevant literature is also presented. CASE REPORT: A young female patient presented with features resembling acute parotitis. Solitary cysticercosis of the parotid gland was diagnosed, based on fine needle aspiration cytology and radiological investigations. Medical therapy was effective, consequently surgery was deferred. CONCLUSION: This is the first report of solitary extracranial cysticercosis of the parotid gland. A high index of suspicion for such parasitic infestations is essential even in non-endemic areas due to the ease of worldwide travel.
