Isolated vertigo is an important symptom of posterior circulation stroke. It has been reported that 11.3% of patients with isolated vertigo have a stroke and that most lesions are located in the cerebellum, particularly in the posterior inferior cerebellar artery. We report the case of a 63-year-old man with multiple atherosclerotic risk factors and atrial fibrillation who showed repeated episodes of isolated vertigo. His repeated vertigo was short-lasting and was often triggered by body position, mimicking benign paroxysmal positional vertigo. Cranial computed tomography on the third hospital day showed left cerebellar infarction within the territory of the posterior inferior cerebellar artery. The vertigo was ameliorated on the fifth hospital day and warfarin was prescribed for secondary prevention. Clinicians should pay special attention to cases in which a patient presents isolated vertigo, even if it shows transient recurrence or is triggered by a positional change, especially in patients with multiple cerebrovascular risk factors.
- Independent risk factors for contralateral patent processus vaginalis undetected by pre-operative ultrasonography in boys with unilateral inguinal hernia. [Journal Article]
- PSPediatr Surg Int 2019; 35(5):591-595
- CONCLUSIONS: We propose that surgeons should consider contralateral evaluation during operation in case with large ipsilateral hernial sac, although CPPV was not detected by pre-operative US.
- A study of contralateral persistent processus vaginalis in laparoscopic hernia repair in children. [Journal Article]
- HHernia 2019 Jan 24
- CONCLUSIONS: The diameters of a hernia and CPPV were identified in the current study, and the diameter was not correlated with increasing age. The incidence of CPPV was more common in patients with left inguinal hernias than in those with right inguinal hernias, and it gradually decreased with increasing age.

Camel contagious ecthyma (CCE) is a viral disease of camelids that is caused by a Parapoxvirus (PPV) which is a DNA virus of the viral family: Poxviridae. Diseases affecting camels in Nigeria are scarcely reported. CCE or the laboratory detection of camel PPV (CPPV) has not been reported in Nigeria. This study investigated and described the clinical presentation of CCE and molecular detection of CPPV in Nigeria. Suspected cases of CCE were reported in a farm, live animal market and abattoir, in three different states (Bauchi, Plateau and Zamfara) in Northern Nigeria. Skin scabs, lungs, liver and intestine samples were collected. Polymerase chain reaction (PCR) was carried out using the primers which targets the RPO30 gene fragment of the genus PPV. The clinical signs observed from the suspected cases of CCE were proliferative skin lesions, papules, scabs on the lips and nares. CPPV was detected in 80.0% (4/5) of the samples collected by PCR. CCE was diagnosed based on clinical signs and PCR results. This is the first report of CCE in Nigeria. Further studies should be carried out to genetically characterize the CPPV circulating in Nigeria.
- Patent Contralateral Processus Vaginalis in Infants and Children: Is Herniotomy Justified? [Journal Article]
- OMOman Med J 2018; 33(6):481-485
- CONCLUSIONS: Inguinal herniotomy for CPPV seems not to be necessary in all cases. This would decrease the use of anesthesia and surgical morbidity in young infants and save hospital resources through avoidance of unnecessary operations.
- Incidence of pediatric metachronous contralateral inguinal hernia and the relationship with contralateral patent processus vaginalis. [Journal Article]
- SESurg Endosc 2019; 33(4):1087-1090
- CONCLUSIONS: Not all CPPVS progress into an MIH, and approximate one of 15 CPPVs would progress into MIH. If patient with initial left-sided inguinal hernia is younger than 3 years old, when the morphology of CPPV is cavernous type identified by laparoscopic exploration, the contralateral repair would be recommended.
- Diagnostic accuracy of preoperative ultrasonography in predicting contralateral inguinal hernia in children: a systematic review and meta-analysis. [Meta-Analysis]
- EREur Radiol 2019; 29(2):866-876
- CONCLUSIONS: Diagnostic accuracy of preoperative ultrasonography to detect CPPV seems promising, though may result in an overestimation of MCIH prevalence, since CPPV does not invariably lead to MCIH. Unequivocal ultrasonographic criteria are mandatory for proper diagnosis of CPPV and subsequent prediction of MCIH.• Diagnostic accuracy of preoperative ultrasonography for detection of CPPV in children with unilateral inguinal hernia is high. • Preoperative ultrasonographic evaluation of the contralateral groin assumedly results in an overestimation of MCIH prevalence. • Unequivocal ultrasonographic criteria are mandatory for proper diagnosis of CPPV and risk factor identification is needed to predict whether CPPV develops into clinically apparent MCIH.

To evaluate the efficacy of laparoscopic percutaneous extraperitoneal closure (LPEC) for unilateral inguinal hernia in children and effect of intraoperative laparoscopic exploration for finding contralateral patent processus vaginalis (CPPV) on prevention of the metachronous contralateral hernia (MCH). We retrospectively analyzed unilateral inguinal hernia ligation in children, which can be diveded into two groups: a total of 252 cases with open surgical ligation from January 2010 to December 2012 (open group), a total of 184 cases underwent laparoscopic percutaneous peritoneal hernia sac high ligation LPEC from January 2013 to March 2015 (LPEC group). Then, we observed postoperative complications, recurrence of hernia, and the postoperative MCH in the two groups and analyzed the influence factors of the MCH. In Open groups and LPEC groups, the complication incidences, respectively, were 4.4 and 1.6 per cent, having statistical difference (P > 0.05), the average postoperative follow-up duration, respectively, were 42 months and 22 months, whereas the overall incidence of MCH, respectively, were 5.2 and 0.5 per cent (P < 0.05). In the first 24 months follow-up time, the overall incidence of MCH, respectively, were 3.6 and 0 per cent. Laparoscopic evaluation was positive for CPPV in 67 cases. We found the prevalence of 56.1 per cent of CPPV in LPEC groups aged 0.6 to 2 years old, finding the incidence gradually decline with the increase of age, until 14.3 per cent to 10 to 12 years old group. Our study shows LPEC has proven efficacy in treatment of unilateral inguinal hernia in children, and routine laparoscopic exploration with this simple maneuver should be actively performed to observe CPPV in all chidren.

Ring expansion metathesis polymerisation (REMP) has proven to be a viable approach to prepare high purity cyclic polymers. Macrocyclic polymers with a fully conjugated defect free backbone are of particular interest as these polymers have no end groups that can act as charge traps. In this work soluble macrocyclic poly(p-phenylenevinylene)s ( cPPVs) have been prepared directly via the REMP of substituted paracyclophanedienes. Single-molecule spectroscopy of the two topological forms of PPV i.e., linear ( lPPV) and cyclic ( cPPV) revealed that lPPV exists in an extended conformation whereas the cPPV adopts a restricted ring-like conformation. Despite such large differences in the chain conformation, the spectral properties of the two compounds are unexpectedly very similar, and are dominated by torsional deformations in relatively short conjugated segments.

- Does the laparoscopic treatment of paediatric hydroceles represent a better alternative to the traditional open repair technique? A retrospective study of 1332 surgeries performed at two centres in China. [Multicenter Study]
- HHernia 2018; 22(4):661-669
- CONCLUSIONS: LPEC is safe, feasible and effective for treating hydroceles in children and has the same recurrence rate as OR. However, LPEC is superior in operation time, hospital stay, occurrence of scrotal oedema, incision infection and occurrence of metachronous hernia or hydrocele. The transumbilical single-site two-port procedure has the same cosmetic effect as the single-port LPEC. According to our experience, the two-port LPEC approach is better for diagnosing cPPV and reducing metachronous hernia or hydrocele than the single-port LPEC procedure.
