We report a case of scoliosis in a 12-year-old girl with Shprintzen–Goldberg syndrome. She was diagnosed with Shprintzen–Goldberg syndrome at birth. She was hospitalized for a surgical treatment because scoliosis gradually progressed. Preoperative X-ray confirmed 80° symptomatic scoliosis in T10–L5. Posterior correction and fusion were performed, and postoperative X-ray showed a correction to 43°in T10-L5. Limited subcutaneous tissues and fragile bones must be considered when selecting the appropriate surgical method. Accurate placement of a screw into thin pedicle is essential to obtain sufficient correction and fusion. The use of a navigation system is recommended.

The Past

There is still no common, universally recognized approach in the therapy of Graves' disease, Gravesism and simple strumas. A number of clinics surgical, therapeutic, nervous, and physiotherapeutic claim to play a role in the treatment of these diseases. The brilliant results of surgical treatment have sufficiently revealed the value of the surgical method, but comparatively young physiotherapy, in particular X-ray therapy, are now actively attracting the attention of specialists to resolve this issue. Thus, if, thanks to the accumulated observations, the participation of each of these clinics is undoubtedly necessary, then the share of participation and the place that belongs to each of them, despite the large number of works on this issue, is still a problem of the day. Only further accumulation of observations on clinical material can bring us closer to solving this problem. That is why it seems interesting to summarize the observations that have accumulated at the Leningrad Physiotherapeutic Institute over the past 6 years (1923-1928 will include). This development also has the advantage that it is made on polyclinic material, which, in contrast to the stationary one with prevailing severe forms, has a variety from initial to classically completed forms.

SummaryThe treatment of femoral head necrosis of adults is still rather problematic. Conservative treatment has been reported relatively unsuccessful and surgical treatment does not show convincing results either. The most effective seems to be a surgical treatment in early stages of the disease, however, the diagnosis still remains relatively complicated. For the late stages (2B and above) the most effective treatment option is represented by core decompression and vascular grafting. However, drilling and plombage (especially when using press-fit technique) seems to be successful, although not excellent. The authors describe their own method of drilling and plombage of the necrotic zone of the femoral head in 41 patients with X-ray detected necrotic changes of the femoral head. The pain measured by VAS was seen to decrease after surgery in all patients significantly. The Jacobs score was also observed to have increased (from fair to good outcome). We have not observed any large femoral head collapse after surgery, moreover, in some cases an improvement of the round shape of the femoral head was seen. It is important to mention that in all cases femoral heads with existing necrotic changes (flattening or collapse) were treated. Although the clinical improvement after surgery was not significantly high, the method we describe is a safe and simple method of diminishing pain in attempt to prepare the femoral head for further treatment in a future, without significant restriction of the indication due to necrosis (osteochondroplasty, resurfacing, THR).

Pharyngeal Tonsil

The pharyngeal tonsil is a lymphatic tissue mass located in the roof of the nasopharynx. The function of the pharyngeal tonsil is to prevent infections with the help of antibodies. Chronic inflammation and allergies lead to hyperplasia of the adenoids that is found almost exclusively in children. The treatment of choice is surgical treatment; conservative treatment is only indicated preoperatively or if surgery is contraindicated. In this paper, we will present a new surgical method for adenoidectomy performed trans-orally with coblation, under endoscopic control.

The detection of the X-ray pulsar signal is important for the autonomous navigation system using X-ray pulsars. In the condition of short observation time and limited number of photons for detection, the noise does not obey the Gaussian distribution. This fact has been little considered extant. In this paper, the model of the X-ray pulsar signal is rebuilt as the nonhomogeneous Poisson distribution and, in the condition of a fixed false alarm rate, a fast detection algorithm based on maximizing the detection probability is proposed. Simulation results show the effectiveness of the proposed detection algorithm.

Objective. To analyze safety and efficacy of X-ray surgical treatment of choledocholithiasis in case of failed endoscopic procedures. Material and methods. A retrospective analysis included 195 patients with choledocholithiasis who underwent X-ray surgical treatment. Primary X-ray surgical intervention was antegrade cholangiostomy. Data of antegrade cholangiography were used to determine type of endobiliary intervention. Antegrade mechanical and pneumatic choledocholithotripsy and lithoextraction, balloon dislocation of stones of the common bile duct into duodenum or jejunum, lithoextraction using rendezvous technique after endoscopic papillotomy through transpapillary drainage tube or a wire were applied. Results. Puncture and drainage of non-dilated bile ducts were successfully performed in 30 (15.4%) patients. There were 212 procedires of cholangiostomy in 195 patients including redo interventions. Complications after cholangiostomy were absent in 92.9% of cases. Minor complications occurred in 7.1% of cases. Antegrade mechanical and pneumatic choledocholithotripsy and lithoextraction was performed in 118 (98.3%) patients. Balloon dislocation of stones of the common bile duct into duodenum was applied in 52 (81.3%) patients. Lithoextraction using rendezvous technique after previous endoscopic papillosphincterotomy was performed in 12 (60%) patients. Six patients underwent transpapillary external-internal drainage of common bile duct. Five patients had stricture of biliodigestive anastomosis complicated by cholelithiasis. Lithotripsy and lithoextraction through antegrade approach or dislocation of stones into jejunum after previous balloon dilatation were performed in these patients. Postoperative mortality was 1.5%. Minimally invasive techniques were absolutely effective for choledocholithiasis in 187 (98.9%) patients. Conclusion. Antegrade X-ray surgical management is effective and safe in patients with choledocholithiasis and unsuccessful previous endoscopic procedures. Integral efficiency of antegrade management of cholelithiasis was 88.8%.

Abstract Background: A Jones fracture is a transverse fracture of the V. metatarsal bone, without significant dislocation in the diaphysis junction and metaphyseal metaphysis. This type of fracture is usually associated with a minimal injury mechanism, and is characterized with minimal swelling, absence of hematoma and prolonged healing. The aim of the presented study was to compare the surgical and conservative therapy of Jones fracture. The study was registered in the www.clinicaltrials.gov database, under the ClinicalTrials.gov ID: NCT04037540 on 27th July 2019. Methods: A total of 27 study subjects were randomized into two groups – Conservative (K): 12, and Operational (O): 15. The study subjects were followed after 6 and 12 weeks using X-ray and the American Orthopedic Foot and Ankle Score (AOFAS). In the absence of X-ray signs of healing and low AOFAS score in Group K, treatment was considered unsuccessful and the patient was indicated for surgical treatment. Results: Five patients in Group K showed no signs of healing on X-ray after 12 to 6 weeks. These patients also manifested poor AOFAS scores and were indicated for surgical treatment and excluded from the study. Fracture failure was observed in seven patients. Their AOFAS scores were at the least satisfactory and, the patients continued in conservative therapy. After 12 weeks, 6 patients manifested fracture healing on X-ray and the AOFAS score of 100. In one patient who refused surgery, the fracture was not healed after 12 weeks. In Group O, seven patients achieved fracture healing on X-ray after 6 weeks, 8 patients did not show fracture healing. The average AOFAS score after 6 weeks was 97 (excellent). After 12 months, 13 patients showed findings of fracture healing on X-ray. The average AOFAS score was 100 points (maximum). Conclusions: The results of the study show that 1) Surgical treatment leads to significantly faster signs of healing on X-ray than the conservative one 2) After six weeks of surgery, 93% (14 out of 15) of patients are able to fully load the limb.

1. The reported 22 cases of unilobar obstructive emphysema in infancy are reviewed. Eighteen of these cases were successfully treated by lobectomy or segmental resection. No cause of the obstruction was found in over 50% of the cases reported. 2. Two cases of unilobar obstructive emphysema in the newborn are presented. These patients were successfully treated by selectively decompressing the emphysematous lobe. 3. The non-surgical method of treatment is advocated in the newborn when lobar emphysema is newly established and reversible. It may be of value when surgery is indicated to improve the patient who is a poor risk. 4. The mechanism, by which selective decompression alleviates the partially obstructed bronchus, is open to conjecture. However, we postulate that the bronchus, is kinked by an overdistended emphysematous lobe and that retained viscid secretions augment the bronchial obstruction in the new born.

Diaphragmatic Hernias

Anterior diaphragmatic hernia (ADH) is a rare congenital pathology that occurs in children with a frequency of 1:4800 (1–6% of all congenital diaphragmatic hernias). There are many controversial aspects in the surgical treatment of patients with ADH: the choice of surgical approach, the method of diaphragmatic repair and the feasibility of excision of the hernial sac. Objective. To conduct a comparative analysis of the surgical treatment of patients with ADH in different clinics, assessing longterm outcomes. Patients and methods. The medical records of 7 children with ADH who underwent surgical repair in different clinics (in time period from 2009 to 2019) were retrospecively reviewed. Evaluating the long-term results of ADH repair was made by telephone and online surveys of the parents of patients and by outpatient examination of children (chest x-ray in two projections). Results. In a ten-year period, 7 patients (4 boys and 3 girls) were operated on with a diagnosis of “anterior diaphragmatic hernia” at the age of 3 months to 12 years. In most children, a hernia was discovered accidentally by chest x-ray. Laparoscopic correction was performed in 5 (71%) cases, thoracoscopic correction – in 2 cases (29%). The main difference in surgical tactics in ADH patients was the manipulation with the hernial sac – the hernial sac was excised in 4 (57%) patients, but it was left in three cases (43%). The defect closure was performed by “full-thickness” separated sutures that fix the diaphragm to the anterior abdominal wall during laparoscopy (5) and to the chest tissue during thoracoscopy (2); in some cases, additional fixation to the rib (4) was performed. Sutures were tied extracorporeally and buried in the subcutaneous layer in 6 (86%) patients. Average follow-up was 7 years. While evaluating long-term outcomes no ADH recurrence were found. Conclusions. There are still many controversial aspects in the surgical treatment of ADH patients. In our opinion, multicenter studies with complex analysis of long-term results are required to standardize the surgical treatment of such patients.

The issues of therapeutic or surgical treatment of chronic choleciscitis, the choice of the most effective therapeutic and surgical method of treatment cannot be considered finally resolved. On the contrary, all these questions are still extremely relevant and topical for the therapist and surgeon and do not leave the pages of the Russian and foreign medical press. And it is not surprising, as our research methods have improved, the boundaries of recognition of these diseases have expanded significantly, and we are convinced that chronic cholecystitis is one of the most common diseases.

In this paper, a nonlinear least squares estimator based on the extending cost function is derived, and its performance is analyzed in a Monte-Carlo simulation. Numerical results show that estimation error of the pulse time of arrival satisfies the normal distribution, the relation between the variance and the number of X-ray photon obtained by our simulation is compared with the analytical model. In addition, the effect of time bin size on the statically behavior of estimation error is also studied. This work holds great promise for designing the parameters of X-ray camera adopted in the pulsar navigation system.
