Treatment of sialorrhea with botulinum toxin A injection in children.

Niger J Clin Pract 2021 Jun;24(6):847-852

Department of Pediatric Pulmonology, Meram Medical Faculty, Necmettin Erbakan University, Konya, Turkey.

Aims: We aimed to evaluate the effectivity and safety of botulinum toxin A (BT-A) to reduce sialorrhea in children with hypersalivation due to neurological diseases.

Methods: Patients who had a complaint of severe sialorrhea were included in the study. Drooling severity of the patients was evaluated using the classification of Thomas-Stonell and Greenberg. The frequency of aspiration before and after the procedure was recorded. The 24-hour saliva amount and mean duration of two consecutive aspirations were recorded. BT-A was injected into the bilateral parotid and submandibular glands by a otorhinolaryngologist under the guidance of ultrasound guidance (USG).

Results: When patients' mean drooling severity scores, drooling frequency scores, mean duration of two consecutive aspirations, and amount of saliva collected before and after procedure were compared, a statistical significance was observed. One-year hospital records before after and injection were examined and it was observed that after BT-A injection, hospital visits were statistically significantly low (P = 0.017).

Conclusion: BT-A injection into salivary glands is well tolerated, is minimally invasive, has low complication rates and should be performed into both parotid and submandibular glands under USG. Although there is still no consensus on the ideal dose and frequency of injections, it is thought that a dose of 1U/kg/gland can be used with safety in pediatric age groups and the dimensions of the salivary glands and quantitative measurements of the amount of saliva should be utilized. Larger studies involving more patients are required in order to constitute a standard injection protocol.

Liver pseudolymphoma (reactive lymphoid hyperplasia): Difficulty in radiological and pathological diagnosis.

Curr Med Imaging 2021 May 4. Epub 2021 May 4.


Pseudolymphoma of the liver (reactive lymphoid hyperplasia) (RLH) is a rare condition. It is usually asymptomatic and detected incidentally on radiological imaging. Imaging features are similar to hepatic adenoma, hepatocellular carcinoma, cholangiocarcinoma, and malignant lymphoma and are not specific for pseudolymphoma of the liver. Percutaneous core biopsy is insufficient to distinguish pseudolymphoma of the liver from low-grade malignant lymphoma and extranodal marginal lymphomas. In this article, we present a case of hepatic RLH of a patient who presented with a skin rash on the leg and was detected incidentally on radiological imaging.

The effects of sevoflurane anesthesia on hemodynamics and cerebral artery diameters in endovascular treatment of intracranial aneurysm: A pilot study.

Ulus Travma Acil Cerrahi Derg 2021 Mar;27(2):200-206

Department of Anaesthesiology and Reanimation, Necmettin Erbakan University Faculty of Medicine, Konya-Turkey.

Background: Cerebral autoregulation is a steady-state of cerebral blood flow despite major changes in arterial blood pressure. Inhalation anesthetics are cerebral vasodilators. In <1 MAC values, the net effect is a moderate decrease in cerebral blood flow and maintenance of responsiveness to carbon dioxide. This study aims to investigate the effects of steady-state sevoflurane anesthesia on hemodynamic and cerebral artery diameter measurements in patients undergoing flow diverter device placement under general anesthesia.

Methods: Forty-six patients aged 18-70 years who underwent flow diverter devices under general anesthesia were included in this study. Routine monitoring was performed on the patients. Mean arterial pressure (MAP) values were recorded. Internal carotid artery, middle cerebral artery and anterior cerebral artery diameter measurements were made from digital subtraction angiography (DSA) images of patients with anterior aneurysms. Baseline artery, right posterior cerebral artery and left posterior cerebral artery diameter measurements were made from DSA images of patients with posterior aneurysms. These measurements were recorded as preoperative measurements. The same measurements were made from the DSA images performed before the Flow diverter device placement procedure performed under steady-state sevoflurane anesthesia for the same patients. These measurements were recorded as peroperative measurements.

Results: The average age of the patients was 56.6±15.1. The MAP of the patients before induction was 76.28±5.13 mmHg, MAP after induction was 64.36±3.23 mmHg, and MAP during sevoflurane anesthesia was 68.26±4.30 mmHg, there was a statistically significant difference. There was a statistically significant difference between the preoperative and perioperative values of anterior cerebral artery diameters. There was a strong relationship between the MAP change percentage and the ICA diameter change percentage (p<0.001, p=-0.785) and a moderate relationship between the MCA diameter change percentage (p=0.033, p=-0.338).

Conclusion: In patients undergoing flow diverter devices, <1 MAC sevoflurane has a hemodynamic effect and creates significant vasodilation in the cerebral artery diameters.

Hydatid Cyst Treatment and Management in Retroperitoneal Organs; Is Percutaneous Drainage an Option?

Urol J 2020 Nov 18;17(6):657-663. Epub 2020 Nov 18.

Department of General Surgery, Meram Medical Faculty, Necmettin Erbakan University, Konya, Turkey.

Purpose: To evaluate patients who cyst hydatid (CH) in their retroperitoneal space and organs in order to determine a standard treatment option for CH.

Materials And Methods: The files of 56 patients who were treated for CH in our clinic were evaluated retrospectively. All patients underwent either percutaneous drainage (PD) or surgery. Patients were divided into two groups as PD (Group one) and surgery groups (Group two). Preoperative and postoperative results were compared statistically.

Results: 31 of 56 patients were male. Mean age of the patient was 39.7 (10-85). 16 patients had been treated with PD and 40 with different surgical interventions such as total cystectomy, partial cystectomy, partial nephrectomy, total nephrectomy, surrenalectomy, and laparoscopic partial surrenalectomy. Patients' followed up was 18 months (6-38m). Relapse was seen in 1 patient who underwent PD. On comparing the results, hospitalization period was prolonged in the surgical group with enlarged cyst presence.

Conclusion: CH presence in the retroperitoneal area is rare. PD, a minimally invasive method, has the potential to be the standard treatment option as it can be performed safely in selected patients. However, currently surgical treatment is considered as the first treatment option after CH diagnosis.

Ultra-mini Percutaneous Hepatolithotomy in Patients With Large and Multiple Hepatolithiasis.

Surg Laparosc Endosc Percutan Tech 2020 Sep 8;31(1):76-84. Epub 2020 Sep 8.

General Surgery, Meram Medical Faculty, Necmettin Erbakan University, Konya, Turkey.

Background: In this study, we applied the ultra-mini percutaneous hepatolithotomy (UM-PHL) technique on hepatolithiasis patients with multiple and large stones on which other minimally invasive methods failed, and our aim was to report its results, sharing in series for the first time.

Materials And Methods: Preoperative and postoperative data, laboratory parameters, radiologic findings, and preoperative and postoperative details were recorded for a total of 14 patients for whom the UM-PHL technique was applied between April 2017 and December 2019. As all patients had multiple stones and extreme stone load and had bile duct surgery, they did not have a normal anatomy. All patients were radiologically confirmed to have had preprocedural magnetic retrograde cholangiopancreatography.

Results: Operation duration of the patients was 137.6±44.9 minutes, while intraoperative blood loss was 69.2±24.9 mL, drainage catheter removal time was 2.85±0.86 days, and the hospitalization time was 4.28±2.55 days. Intraoperative balloon dilation was applied to enlarge the stricture area in 5 patients (35.7%). On the basis of the Clavien-Dindo classification, grade 2 complication was observed in 2 patients (14.2%) due to postoperative cholangitis. Patients were followed up for an average of 15 months, and nonsymptomatic radiologic stone recurrence was detected in the 12th month control of 1 patient (7.1%).

Conclusion: The UM-PHL technique is a successful method that facilitates stone clearance by providing minimal dilatation through percutaneous intervention and by using instruments with small diameter, and it can safely be applied with its low complication level, low recurrence ratio, and short hospitalization time.
