Kikuchi‐fujimoto disease in fine‐needle aspiration smears: A clinico‐cytologic study of 76 cases of KFD and 684 cases of reactive hyperplasia of the lymph node

Kikuchi‐Fujimoto disease (KFD) is cytologically characterized by a polymorphous lymphoid cell population, abundant karyorrhectic debris and histiocytes, many of which are crescentic (Kikuchi histiocytes). As per reviewed literature, KFD may be confused with tuberculosis, lymphoma, and reactive hyperplasia of lymph nodes (RHLN). Since RHLN was found to be a major challenging factor during routine cytodiagnosis of KFD in our material, we tried to find out the differentiating clinico‐cytologic features between 76 KFD and 684 RHLN cases seen in Kuwait. 63.2% of KFD were in 3rd and 4th decades of life as compared to 40.2% of RHLN (P = 0.0002). Male to female ratio was 1: 2.45 for KFD and 1:1.09 for RHLN (P = 0.0022). Kuwaiti:non‐Kuwaiti ratio was 1:2.04 for KFD and 1.31:1 for RHLN (P < 0.0001). Capillary networks was present in 71.1% of KFD smears and 52.6% of RHLN (P = 0.0023). Tingible body macrophages and dendritic reticulum cells were detected in 17.1% and 22.4%, respectively, in KFD as opposed to 50.1% and 58.8%, respectively, in RHLN (P < 0.0001). Kikuchi histiocyte count ranged from 2 to 36% in KFD and was ≥10% in 31 (40.8%). Rare Kikuchi histiocytes were detected in 16 (2.3%) of RHLN cases but in none of them the count exceeded 1%, whereas their count was >1% in all KFD cases (P < 0.0001). Thus, KFD cases differed significantly from RHLN in respect of age and sex distribution, Kuwaiti:non‐Kuwaiti ratio, and cytomorphologic features such as capillary networks, Kikuchi histiocyte count, dendritic reticulum cells, and tingible body macrophages.

Laparoscopic Varicocelectomy in the Management of Chronic Scrotal Pain

Background and Objectives:

To evaluate the usefulness of laparoscopic varicocelectomy in the management of chronic scrotal pain.

Methods:

Between 2009 and 2011, 48 patients in total were treated with laparoscopic varicocelectomy for dull scrotal pain that worsened with physical activity and was attributed to varicoceles. All patients were followed up at 3 and 6 months and biannually thereafter with a physical examination, visual analog scale score, and ultrasonographic scan in selected cases.

Results:

The mean age was 38.2 years (range, 23–54 years). The mean follow-up period was 19.6 months (range, 6–26 months). Bilateral varicoceles were present in 7 patients (14.6%), and a unilateral varicocele was present in 41 (85.4%). The varicocele was grade 3 in 27 patients (56.3%), grade 2 in 20 (41.6%), and grade 1 in 1 (2.1%). The mean preoperative visual analog scale score was 4.8 on a scale from 0 to 10. The mean postoperative visual analog scale score at 3 months was 0.8. After the procedure, 42 patients (87.5%) had a significant improvement in the visual analog scale score (P < .001); 5 (10.4%) had symptom improvement, although it was not statistically significant; and 1 (2.1%) remained unchanged. During follow-up, we observed 5 recurrences (10.4%) whereas de novo hydrocele formation was identified in 4 individuals (8.3%).

Conclusion:

Laparoscopic varicocelectomy is efficient in the treatment of symptomatic varicoceles with a low complication rate. However, careful patient selection is necessary because it appears that individuals presenting with sharp, radiating testicular pain and/or a low-grade varicocele are less likely to benefit from this procedure.     

Influence of Single-file Endodontics on Apical Transportation in Curved Root Canals: An Ex Vivo Micro–Computed Tomographic Study

Introduction

More information regarding the ability of single files to maintain the original canal position is required before adopting a single-file approach to cleaning and shaping. This study compares apical transportation in curved root canals when instrumenting with a single WaveOne (WO) file (Dentsply Tulsa Dental Specialties, Tulsa, OK) in a reciprocating motion with that incurred when using a sequence of Twisted Files (TFs; SybronEndo, Orange, CA) in a continuous rotating motion.

Methods

Forty mesial canals of mandibular molars were evenly allocated into 2 balanced groups (n = 20) with a 17-mm average canal length and 20° average curvature. Canals were accessed in a conventional manner and instrumentation was completed with a single WO file or a series of TFs. The canals were instrumented according to the manufacturers' protocol. Apical transportation was assessed on a comparison of the pre- and postinstrumentation micro–computed tomographic scans at 1-, 2-, 3-, 4-, and 5-mm sections. One-way analysis of variance was performed to assess if a significant difference between systems exists.

Results

No significant difference (P > .05) was found between the WO and TF groups. Transportation in the mesial direction was of greater magnitude than distal transportation for both files systems. The mean transportation in the mesial direction was 100.1 ± 8.8 μm (WO group) and 101.0 ± 10.9 μm (TF group) (P = .5), whereas distal transportation was found to be 80.9 ± 14.6 μm (WO group) and 60.3 ± 11.0 μm (TF group) (P = .3).

Conclusions

The results suggest that no difference exists between the WO file system and the conventional multifile TF system when considering apical transportation in curved canals.

Emergency medical care in developing countries: is it worthwhile?

Prevention is a core value of any health system. Nonetheless, many health problems will continue to occur despite preventive services. A significant burden of diseases in developing countries is caused by time-sensitive illnesses and injuries, such as severe infections, hypoxia caused by respiratory infections, dehydration caused by diarrhoea, intentional and unintentional injuries, postpartum bleeding, and acute myocardial infarction. The provision of timely treatment during life-threatening emergencies is not a priority for many health systems in developing countries. This paper reviews evidence indicating the need to develop and/or strengthen emergency medical care systems in these countries. An argument is made for the role of emergency medical care in improving the health of populations and meeting expectations for access to emergency care. We consider emergency medical care in the community, during transportation, and at first-contact and regional referral facilities. Obstacles to developing effective emergency medical care include a lack of structural models, inappropriate training foci, concerns about cost, and sustainability in the face of a high demand for services. A basic but effective level of emergency medical care responds to perceived and actual community needs and improves the health of populations.     

Total anomalous pulmonary venous drainage with major aorto-pulmonary collaterals - a diagnostic dilemma

A term female newborn presented with right atrial isomerism and infra-diaphragmatic total anomalous pulmonary venous drainage associated with complex cardiac anatomy. The repair was performed utilizing circulatory arrest in deep hypothermia. However, in the post-operative period the patient could not be weaned off mechanical ventilation and underwent cardiac catheterisation. This revealed major aortopulmonary collaterals, which were occluded with coils. We review the literature with specific focus on the occurrence of this unusual combination and its implication in the management during the postoperative period.
