A rare case report - Ovary attached to testicle inside hernia sac.

We report the case of a 67-year-old man, father of 3 children with left indirect inguinal hernia containing uterus with cervix, fallopian tube and an ovary attached to the testicle, also spread ovarian tissue and right congenital cryptorchidism. Coincidentally detected during an operation for left inguinal hernia. Persistent Mullerian duct syndrome is a rare form of male pseudo-hermaphroditism detected coincidently during surgical operation on cryptorchidism or inguinal hernia.

In Vitro Action of Meconium on Bronochomotor Tonus of Newborns with Meconium Aspiration Syndrome.

AIM: Here we studied the role of meconium in the respiratory system on live and exited newborns (weight 250-3000 g). Throughout this study is followed the response of tracheal rings in acetylcholine and histamine in different molar concentrations (10-1, 10-2, 10-3, 10-4 mol/dm3). METHODS: To study the smooth tracheal musculature we used 23 tracheal preparations obtained from the newborns exited from meconium aspiration. RESULTS: Based on the functional analysis of the tracheal specimen we have concluded that the meconium aspiration did not change the smooth musculature response on acetylcholine and histamine when compared to control group, exited from lung inflammatory processes (e.g., pneumonia, bronchopneumonia, atelectasis, cerebral hemorrhage), where tracheal smooth musculature response is significant (P for other causes is not significant (P > 0.01). CONCLUSION: The conclusions suggest that meconium did not potentiate the constrictor action of acetylcholine and histamine in the tracheobronchial system and did not cause modulation of bronchomotor tonus in case of his aspiration. Meconium causes mild relaxation of smooth tracheal musculature with a mechanism which is not mediated by cyclooxygenase products, from tracheal epithelium or proteins. Also, direct activity in the smooth musculature of several tested acids seems to have no significant impact in increasing the tonus of respiratory airway of smooth tracheal musculature.

Influence of hypoxia in bronchial response to bronchoconstrictor substances at newborn with distress respiratory syndrome (DRS).

OBJECTIVE: In this work, role of hypoxia in respiratory system on live and exited newborns weight 250-3000g.) which have died due to different reasons is studied. METHODS: Response of tracheal rings in acetylcholine and histamine in different molar concentrations (10(-4), 10(-3), 10(-2), 10(-1) mol/dm3) was monitored. Study of the tracheal smooth musculature (TSM) tonus was performed in 12 tracheal preparations obtained from the newborns exited due to different reasons. RESULTS: Based on the functional analysis of the isolated tracheal preparations, we have concluded that the cases born with lung atelectasis have caused significant response ofTSM to Acetylcholine and Histamine (p > 0.01). In cases of control group, which has exited due to different reasons from lung inflammatory processes (e.g.: pneumonia, bronchopneumonia, cerebral hemorrhage), Acetylcholine and Histamine have also caused significant constriction of tracheal smooth musculature. CONCLUSION: Results suggest that exited cases with lung atelectasis (hypoxemia) and cases of lung inflammatory processes have significant constrictor action to Acetylcholine and Histamine in tracheobronchial system.

The prevalence of helicobacter pylori infection in patients with reflux esophagitis - our experience.

INTRODUCTION AND AIM: The role of Helicobacter pylori in esophageal disease has not been clearly defined. To clarify this issue, we analyzed 120 patients with histologically confirmed esophageal disease. MATERIAL AND METHODS: In this prospective study, 120 patients who underwent upper endoscopy examination were included; among them 70 patients with clinically, endoscopically and histologically confirmed GERD, and 50 patients with BE. This investigation was performed in the Clinic of Gastrohepatology in Prishtina, during the period: June 2009-December 2011. Each patient was investigated for H. pylori infection, by performing biopsy for HUT test. RESULTS: In BE group, H. pylori infection was present in 16.0% of patients. In GERD group, H. pylori infection was present in 42.9%, and in patients of the control group, in 52.0% of cases. So, in BE group, the prevalence of H. pylori infection showed less significant difference, compared to the control group (P = 0.003) and in GERD group (P = 0.0035). Between GERD group and the control group there was no significant difference (GERD vs. G control. P = 0.421). CONCLUSION: The prevalence of H. pylori infection in patients with BE (16%) was lower in comparison with patients with GERD (42.9%) and with control group (p <0.01). The prevalence of H. pylori infection in patients with BE, especially those with LSBE (9.1%) was very low, which indicates a possible protective role of this microorganism.

Research on alteration of neurons in vagal nuclei in medulla oblongata in newborns with respiratory distress.

Neuronal and axonal degenerative changes in motor vagal neurons (DMNV) and sensory vagal neurons (nTS) in the medulla oblongata in newborns were studied. Material was taken from the autopsies of newborns, live and dead newborns, in different gestational weeks (aborted, immature, premature and mature). 46 cases were studied. Material for research was taken from the medulla oblongata and lung tissue. Serial horizontal incisions were made in the medulla oblongata (± 4 mm), commencing from the obex, where the DMNV and nTS vagal nuclei were explored. Fixed cuttings in buffered formalin (10%) were used for histochemical staining. Serial cuttings were done with a microtome (7 µm). Pulmonary infections, being significant (p < 0.05), have an important place when studying respiratory distress (RD) in newborns. Morphological changes of nerve cells in DMNV and nTS nuclei in the medulla oblongata in newborns in different gestational weeks are more emphasized in matures in comparison to aborted and immature (p < 0.05). Depending on the lifetime of dead newborns, neuronal morphological changes in vagus nerve nuclei are significant (p < 0.05). Therefore, it can be concluded that pulmonary infections are often caused due to dramatic respiratory distress in newborns, while hypoxaemic changes in the population of vagus nerve neurons in respiratory distress are more emphasized in matures.

What are Predictive Factors for Developing of Barrett's Esophagus in Patients with Gerd-our Experience.

INTRODUCTION: Barrett's esophagus (BE) is a condition in which the normal squamous epithelium of the esophagus is replaced with metaplastic intestinal-type epithelium. This epithelium can progress sequentially from metaplasia to low-grade dysplasia, then to high-grade dysplasia and finally to invasive adenocarcinoma. Many factors that appear to be risk factors for the presence of BE include obesity, the presence of hiatal hernia, and interestingly, the absence of Helicobacter pylori infection. THE AIM: The aim of this study was to determine the predictive factors for progression of gastroesophageal reflux disease (GERD) to BE. METHODS: 42 patients with endoscopically diagnosed and histopathologically verified BE were included in this prospective study. We analysed predictive factors such as: age, sex, obesity, alcohol consumption and smoking, reflux symptom duration in this patients, prevalence of short and long segment of BE, and the presence of hiatal hernia. After endoscopic examination of these patients, the presence of BE was verified with histopathological examination and finally, infection with H. pylori was determined. RESULTS: Among 42 subjects, 25 (59%) were males and 17 (41%) were females, with mean age of 52.8±3.28 years. Obesity was present in 24 of 42 patients (57%). 27 of 42 patients (64%) were smokers. Symptom duration in this patients was approximately 9.4 years. From total number of patients, 52% were with SSBE and 48% patients were with LSBE. Hiatal hernia was present in 64% of patients, of which 66% were with LSBE and 34% with SSBE. In these patients, prevalence of infection with H. pylori was present in 12% of cases, 9.5% in patients with SSBE and 2.5% in patients with LSBE. CONCLUSIONS: The important risk factors for appearance of BE in GERD patients were male sex, middle age, smooking and alcohol consumption. Obesity is an important factor for development of BE. Most of patients with BE also had hiatal hernia, in majority of cases these were patients with LSBE. The prevalence of infection with H. Pylori in patients with BE was lower and this may predict a protective role of this microorganism.

In vitro research of the alteration of neurons in vagal core in medulla oblongata at asphyxic deaths.

The aim of this study was to research the morphological changes of neurons in the vagus nerve nuclei in medulla oblongata in asphyxia related death cases. Morphological changes that were investigated were mainly in the dorsal motor respiratory center (DMRC), nucleus tractus solitarius (nTS) and nucleus ambigus (nA) in the medulla oblongata. In our research, the autopsy material from asphyxia related death cases was used from various etiologies: monoxide carbon (CO), liquid drowning, strangulation, electricity, clinical-pathological death, firing weapon, explosive weapon, sharp and blunt objects and death cases due to accident. The material selected for research was taken from medulla oblongata and lungs from all lobes. The material from the medulla oblongata and lungs was fixed in a 10% solution of buffered formalin. Special histochemical methods for central nervous system (CNS) were employed like: Cresyl echt violet, toluidin blue, Sevier-Munger modification and Grimelius. For stereometrical analysis of the quantitative density of the neurons the universal testing system Weibel M42 was used. The acquired results show that in sudden asphyxia related death cases, there are alterations in the nuclei of vagal nerve in form of: central chromatolysis, axonal retraction, axonal fragmentation, intranuclear vacuolization, cytoplasmic vacuolization, edema, condensation and dispersion of substance of Nissl, proliferation of oligodendrocytes, astrocytes and microglia. The altered population of vagus nerve neurons does not show an important statistical significance compared to the overall quantity of the neurons in the nuclei of the vagus nerve (p<0.05).

The study of volume density of tracheal ganglions in vitro in new born babies with respiratory distress syndrome.

Volume density of respiratory organs was studied in vitro in newborn babies at different age of gestation (abort, immature, premature and mature) using stereometric method. The total of 23 cases was subject to this study. The respiratory organs (trachea, lungs) were taken from autopsies of newborn babies exited from different causes. For this purpose the tissues were fixed in formalin (10%) solution, cut serially in 7micro and 10micro slabs. Volume density of the respiratory system was assessed stereometricaly using Universal testing system Weibel M 42. We observed that volume density of epithelia, musculature and glands were proportionally present in the tracheal tissue. Cellular interstitial tissue is consistently increasing and corresponds to the developmental stages of the newborn babies. The density of tracheal ganglions is greater in premature ages of immature and premature newborns (p<0,05). Decreased number of ganglion cells is observed in mature ages (p<0,05). This is caused by intensive ramification of ganglions from serosa to deeper layers of trachea right to epithelium. Medium diameter of tracheal ganglions is greater in mature newborn babies and corresponds to developmental ages of babies.

Role of meconium in the reaction of airways smooth musculature in the newborn with meconium aspiration syndrome (MAS).

The role of meconium in the respiratory system was studied in newborns, who died from various causes (250 up to 3000 g of weight). We monitored tracheal rings response to dopamine, serotonin and ethanol in different concentrations (dopamine: 0,05 mg/ml, 0,5 mg/ml, 5 mg/ml; serotonin (5-HT): 10-4, 10-3, 10-2, 10-1 mol/dm3; ethanol: 0,02 ml, 0,5 ml, 1,0 ml; 96%). Tracheal smooth musculature tonus (TSM) was examined in 48 tracheal preparations taken after the newborn exitus due to different reasons. Based on functional researche of isolated preparations of tracheas, it may be concluded that: aspiration of meconium has not changed the response of TSM to dopamine, serotonin and ethanol (p>0,1) in comparison with the control group, which have died due to different lung inflammatory processes (e.g. pneumonia, bronchopneumonia, atelectasis, cerebral hemorrhage). The results suggest that meconium does not potentiate the constricting action of dopamine, serotonin and ethanol in tracheobronchial system. Meconium causes mild relaxation of the TSM through a mechanism that is not intermediated by the products of cyclooxygenases (prostaglandins, prostacyclins) from the tracheal epithelium or proteins. Also, as it seems, the direct activity of many tested acids in the smooth musculature has no significant impact on increase of the airways tonus in MAS syndrome.

In vitro examination of degenerative evolution of adrenergic nerve endings in pulmonary inflammatory [corrected] processes in newborns.

Morphological aspect of tracheal preparations and pulmonary tissue was studied in vitro. The material was obtained from autopsy of newborns that died from different causes. Examinations were made in different gestational periods (immature 23-29 weeks; premature 30-37 weeks; mature >38 weeks). Material for examination was obtained up to 6 hours after death. Pulmonary and tracheal tissue was incubated for fixation in buffered formalin (10%). Special histochemical and histoenzymatic methods were used for coloring of pulmonary and tracheal tissue and the activity of ATP-ase and dopaoxidase was monitored. Cut out models were made in series of 7 micro, 10 micro and 20 micro. In peripheral axons of tracheobronchial pathways, degenerative alterations of adrenergic nerve endings in lung inflammatory processes were documented. These morphologic neuronal changes were described: Walerians degeneration, neuro-axonal degeneration and segment demyelinisation. These changes are well seen with argentafine coloring (Sevier-Munger modification for nerve endings) and with dopaoxidase reaction. In mature newborns that died from respiratory distress syndrome, we found different forms of metabolic and toxic degenerative damage in peripheral axons, such as: segment demyelinisation, neurotubular fragmentation, Schwann cell proliferation, fragmentation and bulging out of axonal neurotubules and neurofilaments. In tracheo-bronchial tissue, chromafine granules are homogeneously distributed on Lamina propria layer and through glandular structures. This gives as a contradiction, according to some authors, that adrenergic nerve fibers for muscle tissue are absent and that adrenaline and noradrenaline diffuse in muscle tissue from interstice.

In vitro examination of ontogenesis of developing neuronal cells in vagal nuclei in medulla oblongata in newborns.

The development of neuron cells in vagal nerve nuclei in medulla oblongata was studied in vitro in live newborns and stillborns from different cases. Morphological changes were studied in respiratory nuclei of dorsal motor centre (DMNV) and nucleus tractus solitarius (NTS) in medulla oblongata. The material from medulla oblongata was fixated in 10 micro buffered formalin solution. Fixated material was cut in series of 10mu thickness, with starting point from obex in +/- 4 mm thickness. Special histochemical and histoenzymatic methods for central nervous system were used: cresyl echt violet coloring, tolyidin blue, Sevier-Munger modification and Grimelius coloring. In immature newborns (abortions and immature) in dorsal motor nucleus of the vagus (DMNV) population stages S1, S2, S3 are dominant. In neuron population in vagal sensory nuclei (NTS) stages S1, S2 are dominant. In more advanced stages of development of newborns (premature), in DMNV stages S3 and S4 are seen and in NTS stages S2 and S3 are dominant. In mature phase of newborns (maturity) in vagal nucleus DMNV stages S5 and S6 are dominant, while in sensory nucleus NTS stages S4 and S5 are dominant. These data suggest that neuron population in dorsal motor nucleus of the vagus (DMNV) are more advanced in neuronal maturity in comparison with sensory neuron population of vagal sensory nucleus NTS. This occurrence shows that phylogenetic development of motor complex is more advanced than the sensory one, which is expected to take new information's from the extra uterine life after birth (extra uterine vagal phenotype).

Examination of ontogenetic-morphologic growth of adrenergic receptor system in the isolated preparation of trachea in vitro.

Morphological development of the bronchial respiratory system of the living newborns and dead newborns was studied. Tracheal smooth musculature was studied in 19 experimental preparations which were obtained from autopsy of newborns that died from different causes. Based on the morphological research of the isolated preparation of human trachea the following was stated: numerical density of the tracheal ganglions is higher in the premature. Decrease of ganglion cells number is noticed in mature newborns. This can be explained with the fact that in the phase of intensive ramification, ganglions penetrate from the serous layers in the deeper layers of the trachea--in the direction of epithelium. Main diameter of tracheal ganglions is bigger in premature; this is proportional with the developmental phase of newborns. Based on histological, histochemical and hystoenzymatic analyses, three types of synaptic-axonal neurotransmitter vesicles are visualized in our material: small granularvesicles (SGV), large granular vesicles (LGV) and aminoacid vesicles, with gamma-amino butyric acid and glycine (GABA). Vesicles give positive reaction with argentaffin, argyrophilin and dopa-oxidase. Argentaffin and argyrophile reactions are positive in synapses, hydrocyte cartilage, epithelium, smooth musculature, SGV, LGV, GABA of the tracheal-bronchial pathways. ATP is positive in hydrocyte cartilages and tracheobronchial mucus glands. On airways most of the nerve endings are vesicular (motor) type. Non-vesicular (sensory) types of nerve endings are present in perichondrial localization. These morphological data indicate interaction between adrenergic, cholinergic and third nonadrenergic-noncholinergic system in airways.
